The tofu industry in Indonesia is growing rapidly. Tofu liquid waste is usually discharged into the waters and causes water pollution. An efficient way to overcome this problem is to utilize tofu liquid waste. Tofu liquid waste contains proteolytic bacteria that are useful in industry. The increase in bacterial growth is done by adding substances, one of which is the addition of Monosodium Glutamate (MSG). MSG contains glutamate which plays a role in protein synthesis. This study aims to isolate proteolytic bacteria and determine the effect of MSG on the growth of proteolytic bacteria in tofu liquid waste. The research methods included isolation, purification, morphological characterization, calculation of the Proteolytic Index (IP), testing the effect of MSG concentration on growth and protease activity, and data analysis. The MSG concentration used was 0 gr/L; 0.5 gr/L; 1 g/L and 1.5 g/L. The design used was Completely Randomized Design (CRD). The results obtained four isolates with different morphological characteristics. The isolate that had the highest IP value was the fourth isolate of 3,206 and was used for the test. The effect of MSG on growth and protease activity was highest at a concentration of 1.5 g/L at 24 hours. The highest protease enzyme activity was 0.0756 U/mL.

In this work it was investigated the potential of Mucorales fungi isolated from the Caatinga of Pernambuco state for production of biosurfactants using renewable substrates. The strains (Mucor circinelloides UCP 0005, M. circinelloides UCP 0006 and Rhizopus arrhizus UCP 1609) were cultivated in alternative culture media consisting of instant noodle waste (INW), corn steep liquor (CSL) and post-frying soybean oil (PFSO), according to conditions established by a 23 full-factorial design (FFD). The production of biosurfactants was evaluated by determining surface tension and emulsification index (EI24) and statistical analysis was performed using Pareto diagram. The presence of the main sources of carbon and nitrogen in production medium was confirmed by FTIR spectroscopy. According to the results, the three fungi evaluated were able of produce biosurfactant in media containing renewable sources. However, the strain that showed the greatest reduction in surface tension (72 to 27 mN/m) was M. circinelloides UCP 0006 in condition 3 of the FFD (1% INW and 4% CSL, in absence of PFSO). The infrared analysis of the INW showed the presence of carbohydrates, fatty acids and proteins, proving that this is a suitable substrate for the cultivation of fungi. The biosurfactants produced by M. circinelloides UCP 0005 and M. circinelloides UCP 0006 were able to form water-in-oil emulsions and the biosurfactant from R. arrhizus UCP 1609 formed oil-in-water emulsions. The present study demonstrated that the three Mucorales fungi tested were able to produce biosurfactants from renewable sources, with emphasis on M. circinelloides UCP 0006.

Rawa Pening is a semi natural lake which is utilized for hydro-electric power plant, caged fish culture, irrigation, and tourism. It belongs to one of the fifteen lakes which receives national priority to be saved and preserved because of its very poor condition as a result of eutrophication, sedimentation and degraded water quality. Eutrophication of Rawa Pening comes from the Water Catchment Area, originating from farms, animal husbandry, domestic and industrial waste around the lake, and also from the water body itself, that is from caged fish culture. The fertility criteria of the lake water can be determined on the basis of the abundance and variety of phytoplankton and the total phosphorus content. The aim of this research is to find out the water fertility criteria of Lake Rawa Pening based on the abundance and variety of phytoplankton, and the phosphorus content. Research began in July 2012 on three stations. Station I is an area with fishcage culture; Station II is an area without fishcage culture, and Station III is the river inlet or water catchment area. Each station consisted of three different sampling areas. The phytoplankton abundance at the station without fishcage culture is higher (19012 ind/l) than at the fishcage culture station (14356 ind/l) as well as at the inlet station (11058 ind/l), but the diversity index at the no fishcage station is lowest (1.80) compared to the fishcage culture station (2.32) and the inlet station (2.05). The fertility criteria of Rawa Pening based on the phytoplankton abundance and P-total of its water is eutrophic going towards hypereutrophic.

O objetivo do presente trabalho foi ajustar, avaliar e selecionar funções de afilamento para a estimativa de diâmetros ao longo do fuste para espécies florestais comercialmente exploradas na Amazônia Mato-grossense. O estudo foi desenvolvido em unidades de manejo florestal, em áreas de Floresta Amazônica, localizadas no município de Santa Carmem, estado do Mato Grosso. Para o ajuste das funções de afilamento, foram cubadas 449 árvores das espécies florestais Goupia glabra, Qualea albiflora, Trattinnickia burseraefolia, Erisma uncinatam e Mezilaurus itauba. Foram ajustados os modelos não segmentados de Schöepfer (1966), Kozak et al. (1969), Hradetzky (1976) e Demaerschalk (1972) adaptado por Moura (1994) e o modelo segmentado de Max e Burkhart (1976). Para avaliar a acuracidade dos ajustes, foi utilizado o coeficiente de determinação ajustado, o erro padrão de estimativa em porcentagem e a análise gráfica dos resíduos, além do valor ponderado dos escores estatísticos e do cálculo das estatísticas auxiliares: desvio, desvio padrão das diferenças, somatório dos quadrados dos resíduos relativos e resíduos percentuais. A função de afilamento de Demaerschalk (1972) adaptada foi a mais acurada para estimar os diâmetros ao longo do fuste de espécies florestais da Amazônia Mato-grossense. Essa função permite descrever a forma dos troncos e possibilita a determinação de sortimentos para múltiplos produtos da madeira.Palavras-chave: Floresta Amazônica; taper; valor ponderado de escores estatísticos. AbstractEvaluation of taper functions for diameter estimated of commercial forest species in amazon matogrossense biome. The aim of this work was to adjust, evaluate and select taper functions for estimating diameters along the stem for commercially exploited species in the Amazon Rainforest in Mato Grosso State. The research was conducted in forest management units in areas of the Amazon Rainforest, located in Santa Carmen, Mato Grosso State. To adjust the taper functions, 449 trees were cubed, of the following species: Goupia glabra, Qualea albiflora, Trattinnickia burseraefolia, Erisma uncinatam and Mezilaurus Itauba. The non-segmented models of Schöepfer (1966), Kozak et al. (1969), Hradetzky (1976), and Demaerschalk (1972), adapted for Moura (1994), and segmented model of Max e Burkhart (1976) were fitted. In order to evaluate the accuracy of adjustments we used the determination coefficient, standard error of estimate in percentage and graphical analysis of the waste, weighted value of statistical scores, and auxiliary statistics: standard deviation, standard deviation of differences, sum of squared residuals and relative percent residue. The function of taper Demaerschalk (1972) was the most accurate to estimate the diameter along the stem for forest species of Amazon Matogrossense. Such function allows to describe the shape of the stem as well as the possibility of determining assortments for multiple products of wood.

The main problems of mankind in recent decades are the accumulation of various industrial, agricultural, and food production wastes. Their ineffective disposal and management practices have a detrimental effect on human health and cause environmental pollution, which requires urgent action. Food waste has become a complex phenomenon lately, attracting the attention of scientists, consumers, and activists. This study aims to apply the biotechnology of converting food waste into crystals of polylactic acid (PLA), a monomer for biodegradable plastic. A food waste sample is taken from the student canteen; wash, to remove impurities and fermentation of carbohydrate waste by autotrophic lactic acid bacteria in a natural process for about seven days in the optimal temperature range. Finally, lactic acid molecules polymerized by condensation reaction to form poly L-lactic acid (PLA) crystals, and then a biodegradable bioplastic.

Corn straw as agricultural waste is a source of feed for ruminants which has a high fiber content and still contains good nutritional value and is sufficiently available. Unfortunately, this potency has not been fully utilized by the farmer as animal feed. This condition is found in almost all regions in NTB because we still see a lot of corn straw or corn waste in general, a lot of which is wasted even burned by the community. One of the efforts that need be made so that it can be used as a source of feed is by knowing the production of corn straw and its potential as feed for ruminants in Bolo District, Bima Regency. The research was carried out by survey method by using a questionnaire. The research results showed that the area of maize plants in Bolo District was 4,041.88 hectares with a harvest area of 3,024.76 hectares. The production of corn waste consisting of stalks, leaves, husks, cobs and silk was 3,629.66 tons in dry matter. The population of ruminants (cattle, buffalo, goats and sheep) is 10,008 heads with the largest livestock population is the cattle. From the calculation between the amount of corn waste production and the ruminant livestock population in Bolo District, Bima Regency, it can be concluded that corn waste has a high potential as feed, which is 19 percent.

An experimental finfish aquaculture farm was operated in a small lake at the Experimental Lakes Area in northwestern Ontario, Canada. In this study, we used the distinct and enriched carbon and nitrogen isotope ratios (δ13C and δ15N) of rainbow trout ( Oncorhynchus mykiss ) feed and waste to determine whether the operation provided a novel source of energy for native biota. For 1 year prior to and for 3 years during the cage culture, we collected littoral, pelagic, and profundal invertebrates and minnows from the experimental and reference lakes. In both the second and third years of aquaculture, there was a significant increase in δ15N of all organisms sampled in the experimental lake; mean δ15N values of littoral, pelagic, and profundal invertebrates and minnows shifted towards the signature of the fish feed by up to 4.2‰. Significant increases in δ13C of up to 2.6‰ were observed in Mysis , profundal chironomids, and minnows but not in littoral invertebrates or zooplankton. Aquaculture waste became a progressively more important component of minnow diets over the course of this study. The dissolved and (or) particulate wastes of the cage operation became a novel source of energy for the native biota in this experimental lake.

Environmental pollution caused by waste is pollution that very dangerous for living things. In particular, water pollution, waste that is disposed of through waterways will disrupt the water ecosystem which will have an impact on human life. On the other hand, the development of entrepreneurship such as home industry has a positive impact on society, especially in terms of the economy. Therefore, water pollution indicators are needed that can be used as guidelines in treating wastes such as BOD and COD. In this study, analyzed the levels of BOD and COD from home industry wastewater in the Cawang area. The home industry includes laundry, cracker business, restaurants, printing houses, photocopying, and snack businesses. Based on the results of data analysis, the highest BOD level was 45.827 in samples taken at night. And, the highest COD levels were 95.923 in samples taken at night. These data indicate that the levels of BOD and COD in the water in the home industry waste disposal sites are below the standard threshold for wastewater quality. The levels of BOD and COD are in the safe category for aquatic biota. Keywords: BOD levels, COD levels, Waste, Water pollution

Electrical and electronic gadgets (or E-gadgets) have become indispensable components of our daily life these days. As today’s electrical and electronic devices become tomorrow’s waste, the potential hazards of these materials in an open environment are significant, as they can contaminate soil, drinking water, air and thus directly affecting human health and surrounding biota. With time, the random disposal of these wastes may lead to a disastrous situation. Although Nepal is one of the least developed countries, also in terms of electrical and electronic equipment, we are importing the high-tech E-gadgets from the developed nations and using them without a proper vision for their after-use management and their impacts on socio-economic values as well as health and environment. It has become an urgent need of the hour to address E-waste challenges taking into consideration the best suited international policies and practices.

The bivalve anadara grandis is one of the most abundant shells which are easy to find in Indonesian waters. The number of clams consumed is directly proportional to the amount of clamshell waste, which the most part is only disposed into waste. Coral reef has a very important purpose in supporting activities in coastal areas. Artificial reef is a structure that has aim to restore the biological purpose coral reef that have been damaged. This study aims to compare the effectiveness of the use of normal concrete (made from sand, cement dan splits only) than clamshell mixture as materials of artificial reef. A field research was conducted in Pasir Putih, Situbondo, with visual descriptive method (transect with a quadrant of 25 x 25cm) and underwater camera as an aid to facilitate the observation. During the 4-month observation of the drowning, nine types of biotas were found in attaching, with the dominant biota attached to these artificial reef were bivalves, barnacles, and bryozoan. Results show that the total number and density of calcareous biota attached on clamshell concretes are higher than those of standard concretes. So, it could be concluded that the concrete reefs made of clamshells resulted in attachment of biota slightly higher than it of normal concretes and the benefits of both materials can form the coral reef ecosystem well. In particular, the use of artificial reef with a mixture of clamshells is better than normal concrete because its more effective for algae attachment and cheaper because low budget due to the material availability of clamshell presently as damage and wastes in coastal area.

Plastic pollution is ubiquitous throughout the world’s ecosystem. Increase in the world’s plastic production and use, inefficient recycling, indiscriminate disposal, synthetic nature and non-biodegradability of plastics have made it a considerable threat to biodiversity. The impact of plastic wastes on humans and the environment is becoming apparent. However, information on the impacts of plastic wastes on biodiversity is mostly directed towards marine environment with scarce information on land biodiversity although terrestrial environment is the major source of marine contamination. Terrestrial plastic waste contaminants are derived from long term used plastic containers and single-use plastic products, which are introduced by anthropological means, flood water, sewage and wind dispersal. Gradual breakdown of large plastic wastes give rise to microplastics, which increase its abundance in the environment. Plastics threaten wildlife in terms of entanglements, ingestion and chocking, which often results in loss of body parts or mortality. Plastics as vectors of invasive species in marine ecosystem have been widely established. Although not much is known on the importation of invasive species on terrestrial ecosystem by plastic wastes, there is possibility that plastic waste can be a potential vector of terrestrial alien species. Contamination of soil with microplastics alters soil habitats and disturbs the natural biophysical properties of the soil environment that leaves a negative impact on soil biota by reducing their activities and indirectly affecting food production. Accumulation of plastic wastes provides breeding ground for disease vectors, which has contributed to increased prevalence of emerging infectious diseases. This review examines the impact of plastic wastes on terrestrial biodiversity as it affects soil organisms, land animals and breeding of disease vectors.

Abstract: Toxicity Test Of Acute Industrial Waste Water On Tilapia Fish (Oreochromis Niloticus). The sasirangan industrial liquid wastes containing high ammonia and high pH when discharged into the receiving water body without treatment will result in changes in water quality and even the death of aquatic biota so that an acute toxicity test is necessary. This study aims to determine the value of LC50 from waste sasirangan against tilapiaI. This research used the experimental method of Post Control Only Control Group Design design. Samples taken as much as 100 liters of waste in one industry sasirangan existing in the city of Banjarmasin. Concentrations of the sasirangan waste solution to be used in the acute toxicity test are: 4, 8, 12, 16 and 20%. Parameters studied include ammonia, DO, pH, and temperature. To determine the value of LC50 using probit analysis. The results showed that LC50 for exposure time 24, 48, 72 and 96 hours were 14.73%, 10.21%, 8.26%, and 7.35%, respectively. The results of the analysis show that pH and ammonia content of industrial effluent sasirangan affect the death of tilapia fish. This research is hoped that the sasirangan industry does not dispose of its waste directly to the water body but needs to process it first. For further research it can complement the untested parameters such as BOD, COD, and TSS that affect fish survival.

The management of long-lived mining wastes is a complex environmental challenge, but the subject is little discussed among the public, scientific community, and policymakers. The negative environmental impacts caused by mining wastes are severe and cause damage to human health and the loss and degradation of natural ecosystems. With the objective of stimulating discussion to advance the development of measures to contain threats to biodiversity and to mitigate negative impacts, we present an overview of total volumes of mining waste disposal in tailings dams and dump piles, discriminating them by ore type and biome. We highlight the major environmental risks and challenges associated with tropical forests, savannas, and freshwater ecosystems and possible limitations and advances in public policies and governance. The scale of this challenge is global, as some data show, for example, Brazil generated 3.6 billion tons of solid mining waste in dump piles in the period between 2008 and 2019. The volume is equivalent to 62% of the global mass of nonfuel minerals removed from the planet’s crust in 2006. Numerous socio-environmental disasters are caused by catastrophic mining dam failures, and over the last 34 years, an average of one failure has occurred every three years in Brazil.

The disposal of vegetable wastes in nature is harmful for marine habitats and biota. These types of waste are frequently used as fuel, generating polluting products, with undesired side effects on the environment. Therefore, it is essential to find better alternatives for the capitalisation of these waste products. Their diversified chemical composition can become a potential resource of high added value raw materials. The knowledge of the physicochemical properties of these wastes is therefore essential. The present work aimed for characterising the physicochemical properties of a plant residue belonging to the Asteraceae Family, collected from a vegetable market in Fez city, Morocco. The vegetal tissues were analysed by Scanning Electron Microscopy coupled with EDX, X-ray Diffraction, Fourier Transform Infrared Spectroscopy, Inductively Coupled Plasma Atomic Emission Spectroscopy, and by Thermogravimetric/Differential thermal analyses. Other additional parameters were also measured, such as moisture, volatile matter, ash, and fixed carbon contents. Acidic and basic surface functions were evaluated by Boehm’s method, and pH points at zero charge were equally calculated. The results revealed a strong congruence between the morphological and structural properties of this plant. These vegetal wastes comprise a homogeneous fibrous and porous aspect both in surface and in profile, with a crystalline structure characteristic of cellulose I. A mass loss of 86.49% for leaves and 87.91% for stems in the temperature range of 100 °C to 700 °C, and pHpzc of 8.39 for leaves and 7.35 for stems were found. This study clarifies the similarities and differences between the chemical composition and morphological structure of these vegetal wastes, paving the way for future value-added applications in appropriate fields.

ABSTRAK Kali Wiso merupakan sungai yang berada di tengah kota Jepara. Perairan ini menjadi tempat pembuangan limbah-limbah secara langsung. Limbah tersebut diantaranya limbah domestik, limbah pasar, limbah kapal, serta limbah TPI. Berdasarkan masukan limbah tersebut menjadikan muara ini tercemar. Perairan yang tercemar dapat dilihat dari pengamatan secara fisika, kimia, maupun biologis. Kondisi perairan yang tercemar secara biologis dilihat dari keberadaan bakteri patogen yang ada di perairan. Indikator bakteri yang digunakan yaitu bakteri coliform, karena sifatnya yang berkorelasi positif dengan bakteri patogen lainnya. Pemanfaatan perairan ini digunakan untuk kegiatan pelabuhan, tempat bersandar kapal nelayan, serta kegiatan perikanan yang ada di sekitar perairan Jepara. Oleh karena itu perlu diketahui kepadatan bakteri coliform sehingga dapat bermanfaat sesuai dengan peruntukannya. Tujuan dari penelitian ini adalah untuk mengetahui total bakteri coliform serta mengetahui adanya bakteri Escherichia coli. Penelitain ini dilakukan pada bulan Maret 2016 di Muara Kali Wiso dengan dua kali pengulangan dalam kondisi pasang dan surut. Metode yang digunakan yaitu survei dengan teknik sampling purposive sampling. Metode analisa laboratorium yang digunakan berdasarkan SNI -01-2332-1991. Kepadatan bakteri coliform pada perairan muara Kali Wiso yaitu >110.000 sel/100ml dan bakteri Escherichia coli sebesar >110.000 sel/100ml. Pada kondisi pasang dan surut kepadatan bakteri coliform dan Escherichia coli memiliki nilai perikaraan yang sama, namun tidak menandakan bahwa total bakteri keduanya sama. Kepadatan bakteri coliform dan Escherichia coli telah melebihi batas kriteria mutu air yang telah ditetapkan. Keberadaan bakteri patogen ini bisa mengkontaminasi biota-biota yang ada di perairan. Sehingga jika biota tersebut dikonsumsi oleh manusia bisa menyebabkan gangguan kesehatan secara tidak langsung.

The aim of this study was to investigate the effects of reusable organic wastes on soil organisms, with a focus on changes in the soil food web. Bone meal, de-oiled cake, and oyster shell were applied at 5 t ha–1, and the abundance and biomass of soil organisms were measured at 4, 8, and 13 weeks after treatment in soil under eggplant cultivation. The abundance of microflora and fauna was higher in the soils treated with bone meal or de-oiled cake than in untreated soils, suggesting that soil organisms are affected by the quality of applied organic wastes. Increases in the abundance of bacterivorous nematodes were observed under treatment with bone meal or de-oiled cake, but there was little change in the abundance of predatory nematodes. A positive response of microarthropods in the Collembola and Oribatida was apparent, and these organisms are involved as secondary consumers in the soil food web, but the predaceous Gamasida were relatively unaffected. The abundance of protozoa, microbivorous nematodes, Collembola, and Oribatida was correlated with the abundance of bacteria and fungi, indicating that both bacteria- and fungi-based food webs formed. The abundance of the secondary consumers was not significantly correlated with that of the predators. The study suggested that, in the short-term, organic waste alters the primary and secondary consumers but its effect may not extend to predators.

Abstract Cleaner production is an environmental processing strategy that is implemented on an ongoing basis to increase eco-efficiency in order to reduce risks to human health and the environment. The tofu industry in its production process produces waste, both solid and water. Disposal of waste directly to water bodies will damage the environment by creating unpleasant odors and the hot temperature of waste water which can affect the growth of aquatic biota. Tofu production produces 150 L of liquid waste from the soaking and filtering process. Meanwhile, 50 kg of solid waste is produced from milling soybeans. Solid waste will be used as animal feed and liquid waste will be processed into liquid compost. Keywords: Tofu Production, Cleaner Production, Liquid Compos, Waste Minimization, Mass Balance. Abstrak Produksi bersih merupakan strategi pengolahan lingkingan yang diterapkan secara berkelanjutan untuk meningkatkan ekofisiensi agar dapat mengurangi resiko terhadapat kesehatan manusia dan lingkungan. Industri tahu dalam proses produksinya menghasilkan limbah, baik padat maupun air. Pembuangan limbah langsung ke badan air akan merusak lingkungan dengan timbulnya bau tidak sedap dan suhu air limbah yang panas dapat mempengaruhi pertumbuhan biota air. Produksi tahu menghasilkan limbah cair sebanyak 150 L dari proses perendaman, dan penyaringan. Sedangkan limbah padat yang dihasilkan sebanyak 50 kg yang berasal dari penggilingan kacang kedelai. Limbah padat akan dijadikan pakan ternak dan limbah cair akan diolah menjadi pupuk kompos cair. Kata Kunci : Industri Tahu, Produksi Bersih, Pupuk Kompos, Minimasi Limbah, Neraca Massa.

HYDRODYNAMICS EFFECT TO THE DISTRIBUTION OF THERMAL WASTE IN THE OCEAN. The ocean is a thermal waste disposal site derived from thermal power plants. The ecosystems and marine biota could be disrupted even massive damaged if this waste was disposed into the ocean without proper processing. All activities in the ocean need a well understanding of hydrodynamics to avoid or minimize any negative effects that may occur. It needs dispersion modeling of heat water prior to the construction of the power plant in order to reduce the impact of environmental damage.

The addition of 60Co and 134Cs to the anaerobic hypolimnion of a thermally stratified Canadian Shield lake in summer initially isolated the exposure of biota to only zooplankton that undergo vertical migration into this region of the lake. Once the radionuclides became mixed throughout the water column with autumn turnover, other biota were exposed to the radionuclides. In general, 60Co concentrations in biota were low because of the rapid loss to the sediments. Exceptions were for initial 60Co concentrations in filter-feeders (cladocerans and clams) during autumn turnover. Concentrations of 134Cs were higher in biota the following spring and summer, reflecting the tendency of 134Cs to remain in the water column. Concentrations of 134Cs still continued to increase in forage fish 1 year following the radionuclide addition. The addition of radionuclides to the hypolimnion resulted in higher concentrations in forage fish than when added to the epilimnion. Radionuclide concentrations in biota varied with taxon and were greatest in periphyton. This study demonstrates that radionuclides that may enter the bottom waters of a lake as a result of nuclear fuel waste disposal will be available to biota and result in a radiation dose to aquatic biota and to humans via the water-fish-human pathway.

The prime constraint upon the development of a tidal power generating barrage is the use of the Mersey estuary as a waste disposal facility. Historical disposal of persistent wastes continues to cause environmnetal problems, even though modern practices have resulted in a reduced pollution load. Mercury and lead have the greatest environmental significance, although with reference to barrage operation the nutrient status and increased transmission of light through less turbid water will be of equal or greater importance. A constraint upon the recreational use of the impounded water body will be the unacceptable numbers of faecal bacteria. A criterion for the design of the barrage should be the maximisation of the volume of water entering on each tidal cycle to disperse nutrients and pollutants and import as much oxygen as possible. This will minimise the increase of retention time and reduce the probability of methylation of mercury within the sediment. Additionally it will have implications for the feeding behaviour of the internationally important wildfowl populations.

As a result of very rapid technological advances in this day and age, the ecosystem of life on earth is disrupted. Not only on land, there is damage to ecosystems in the sea, especially those caused by human activities that make the sea a place for waste disposal, both in the form of garbage and industry. The disruption of the ecosystem causes the life of marine biota to be preserved and educated to the public. One way to overcome the marine biota ecosystem caused by the lack of public awareness of the life of the marine biota is through education combined with tourism or seaside recreation. The issue of going beyond ecology to architecture for goodness and life as the theme of Stupa 8, provides ideas on how architecture can play a role in helping to maintain the ecosystem of life in the sea. As an effort to answer how architecture can play a role in community life, from the issues raised, an approach is used using contextual design methods. This method is used so that there is a context of marine life in the Sunda Kelapa environment which is the location of the site. Contextual is used as a design method by taking into account existing activities and the history of the existence of the Sunda Kelapa port and the existence of the first aquarium in Jakarta. With the presence of a marine biota museum that will be designed in the Sunda Kelapa Harbor area, it will complement the existence of a maritime museum, a hexagonal market as a means of tourism and community recreation. By utilizing multi-media technology in demonstrating museum materials and the existence of an aquarium, it is hoped that it can attract people to want to visit the museum. And especially can play a role in educating the public to be more concerned about marine life that is increasingly polluted. Keywords: Technology Advancement; Beyond Ecology; History and Culture; Plastic waste Pollution AbstrakKemajuan teknologi yang sangat pesat pada zaman sekarang ini, membuat ekosistem kehidupan di bumi menjadi terganggu. Bukan hanya di darat saja terjadi kerusakan ekosistem di laut pun terutama yang disebabkan oleh ulah manusis yang menjadikan laut sebagai tempat pembuangan kotoran baik berupa sampah maupun industri. Salah satu cara mengatasi ekosistem biota laut yang disebabkan oleh kurangnya kesadaran masyarakat terhadap kehidupan biota di laut adalah melalui edukasi yang digabungkan dengan wisata atau rekreasi tepi laut. Isu melampaui ekologi menuju arsitektur untuk kebaikan dan kehidupan sebagai tema soal Stupa 8, memberikan pemikiran bagaimana arsitektur dapat ikut berperan dalam menjaga ekosistem kehidupan di laut. Dalam menjawab peran arsitektur dapat dalam kehidupan di masyarakat, berdasarkan isu dilakukan pendekatan yang menggunakan metode perancangan kontekstual. Metode ini digunakan agar terjadi konteks dari kehidupan biota laut terhadap lingkungan Sunda Kelapa yang menjadi lokasi tapak. Kontekstual yang dijadikan metode perancangan dengan memperhatikan kegiatan yang sudah ada serta sejarah keberadaan Pelabuhan Sunda Kelapa serta pernah adanya aquarium pertama di Jakarta. Kehadiran museum biota laut di area Pelabuhan Sunda Kelapa ini, akan melengkapi keberadaan museum bahari, pasar hexagonal sebagai sarana wisata dan rekreasi masyarakat di kawasan kota tua. Dengan memanfaatkan teknologi multi media dalam peragaan materi museum serta adanya aquarium diharapkan dapat menjadi daya tarik masyarakat untuk ingin berkunjung ke museum. Dan terutama dapat berperan mengedukasi masyarakat agar lebih peduli terhadap kehidupan laut yang semakin tercemar.

Summary Organic fertilization has been shown to benefit soil biota. A field experiment was established in 1991 at the AGES experimental research station Ritzlhof to investigate the effects of long-term fertilization on soil biota and crop yields. Experimental plots were cultivated using a crop rotation with maize, wheat, barley, and pea. Eight treatments consisted of compost application (urban organic waste, green waste, cattle manure, and sewage sludge compost). Composts were applied exclusively (organic) or amended with mineral nitrogen (N) fertilizers (80 kg N ha−1, organic-mineral) and compared to 0 (control) and mineral (40, 80, and 120 kg N ha−1) fertilization. Earthworm activity and biomass, litter decomposition, crop growth, and yield parameters were investigated under winter barley (Hordeum vulgare L.) in 2014 after uniform mineral fertilization and 1.5 years after the last compost application. Earthworm activity was significantly increased under long-term organic-mineral fertilization compared to the control, whereas earthworm biomass was unaffected by compost application. Litter decomposition rate was highest in the control. Only barley stem growth was affected by fertilization, whereas other barley parameters including yield were unaffected. The results showed that long-term fertilization affects soil biota even if compost is not applied every year.

The aim of the work is to investigate the influence of man-made edaphotopes of colliery spoil heap on biota by bioindication method. The physicochemical properties of edaphotopes were investigated: humidity, substrate temperature, humus content at different intervals of their depth and on different sections of the waste heap. The storage technologies of mineral waste in the dumps disregard its further use and transforming that occurs over time. It was revealed that on the northern slope exposures the greatest amount of moisture was concentrated and temperature regimes were acceptable for the activity of the soil biota, which was proved by the largest amount of biomass. New dependences of humus content in edaphotopes of the heap in different intervals of their depth from biomass of humus-forming organisms were established. Slight successional processes on the surface of the heap were observed, where young flora began to develop. This positive phenomenon will contribute to the humus of the genetic horizons and the development of tree and shrub vegetation. Favourable conditions for the development of neo-terrain and the formation of a new landscape in mining regions were confirmed.

The extensive production of polymer plastics and their use in different commercial applications had burdened the municipal in cost and operation of the waste management system. This unwanted waste had also posed a significant threat to the environmental surroundings which destroyed biota. Hence, alternatives called bio-plastic evolved as the development of renewable resource by utilizing agricultural, eggshells and exo-skeleton seafood (chitosan) wastes instead of petroleum sources. The aim of this research is to use the eggshells and chitosan as fillers in potato starch to overcome the inherent drawbacks of bio-plastic. The experimental study was done on tensile strength, water absorption and biodegradability for potato starch-based bio-plastic with eggshells or chitosan. The results showed that by adding the eggshells into the potato starch-based bio-plastic had increased the tensile strength by 4.94% compared with chitosan only 1.28%. The reduction of water absorption by 10.95% was determined using eggshells as fillers. Meanwhile, the used of chitosan resulted in 27.59% reduction in water absorption. In eggshells, the weight loss in biodegradability test was 21.06% compared to chitosan of 7.9% within 20 days. It can be concluded that eggshells as fillers performed much better that chitosan in potato starch-based bio-plastic. It also can be deduced that adding fillers in starch-based bio-plastics can improve the bio-plastic performance.

Advanced agronomic methods, urbanisation, and industrial expansion contaminate air, water and soil, globally. Agricultural and industrial activities threaten living biota, causing biodiversity loss and serious diseases. Strategies such as bioremediation and physiochemical remediation have not been effectively beneficial at treating pollutants. Metal-based nanoparticles (NPs) such as copper, zinc, silver, gold, etc., in various nanoformulations and nanocomposites are used more and more as they effectively resist the uptake of toxic compounds via plants by facilitating their immobilisation. According to studies, bio-based NP synthesis is a recent and agroecologically friendly approach for remediating environmental waste, which is effective against carcinogens, heavy metal contamination, treating marine water polluted with excessive concentrations of phosphorus, nitrogen and harmful algae, and hazardous dye- and pesticide-contaminated water. Biogenic resources such as bacteria, fungi, algae and plants are extensively used for the biosynthesis of NPs, particularly metallic NPs. Strategies involving green synthesis of NPs are nontoxic and could be employed for commercial scale production. Here, the focus is on the green synthesis of NPs for reduction of hazardous wastes to help with the clean-up process.

The article summarizes the accounting and informational evaluation of the financial and economic efficiency of agricultural enterprises environmental management. There is a tendency to reduce the use of pesticides in agro-industrial production, which indicates the desire of producers to produce organic products with a minimum amount of chemicals. The national trend of introduction of waste-free or low-waste production is analyzed. A set of indicators for assessing the effectiveness of the environmental management system of agricultural enterprises based on indicators of impact on the environment and biota (allows to determine the depth of environmental impact from the activities of agricultural enterprises), indicators of attracting production potential of the enterprise for greening between the consumed and reproduced resource of the enterprise) and nature conservation and indicators of financial costs for nature conservation (determine the amount of costs incurred by the agricultural enterprise for the preservation of the environment and biota). To assess the effectiveness of the environmental management system of agricultural enterprises, it is proposed to determine its comprehensive indicator according to these three components. The ranking scale of the complex indicator is developed and its dependence on the coefficient of emissions of hazardous substances into the air by the agricultural enterprise is determined; the coefficient of wastewater emissions into the environment by an agricultural enterprise; the coefficient of waste-free production by an agricultural enterprise; the coefficient of impact on the environment due to accidents at the enterprise; the coefficient of costs for the protection of the natural environment and biota; coefficient of investments involved in the protection of the natural environment and biota; current liquidity ratio; the coefficient of renewal of obsolete fixed assets for environmentally friendly; depreciation ratio; depreciation ratio of fixed assets; coefficient of environmental friendliness of production processes. A ranking scale for each of the components of the integrated indicator is proposed. The prospect of further research is determined, which is based on the need to test the evaluation of the effectiveness of the environmental management system on the proposed indicators on the example of agricultural enterprises of Ukraine.
