Abstract:

Tujuan tulisan ini memaparkan hasil identifikasi dan potensi pemanfaatan limbah perikanan di Banda Aceh. Hasil kajian menunjukkan bahwa limbah yang dihasilkan dari usaha perikanan (penangkapan, budidaya, pengolahan) dan usaha non-perikanan sebagian besar belum dimanfaatkan secara optimal. Limbah yang dihasilkan dari usaha penangkapan adalah limbah padat berupa sisa ikan hasil pembongkaran dengan status sudah dimanfaatkan untuk pakan unggas. Limbah dari usaha pengolahan antara lain limbah padat berupa sisa ikan bagian kepala, isi perut dan tulang dengan status belum dimanfaatkan karena terbatasnya pengetahuan dan keterampilan dalam mengadopsi teknologi. Limbah dari usaha budidaya berupa padatan yang sudah dimanfaatkan sebagai pupuk kompos, sedangkan limbah dari budidaya kepiting soka belum dimanfaatkan. Jenis usaha yang berpotensi untuk dikembangkan dengan memanfaatkan limbah tersebut adalah: 1) usaha tepung ikan; 2) usaha pembuatan pakan ikan dan unggas; 3) usaha olahan makanan ringan (snack) tulang ikan; 4) usaha kerajinan aksesoris berupa tas atau dompet; 5) usaha pembuatan tepung bahan baku citosan.Title: Potential Use of Fisheries Waste in Banda AcehThis paper aimed to describe the identification of fisheries waste management in Banda Aceh. Results showed that waste from fisheries (catching, aquaculture, fish processing) and non-fisheries activities largely untapped optimally. Solid waste from marine captured fisheries is demolition of the remaining fish with status already used for poultry feed. Waste from processing businesses include solid waste such as leftover fish head, entrails and bone status untapped due to limited knowledge and skills in adopting technology. Waste from aguaculture in the form of solids that have been used as compost, while soft-shelled crab waste from aquaculture untapped. Type of business which have potential to be developed by utilizing the waste are: 1) business of fish meal; 2) business of making fish feed and poultry; 3) business of processed snack fish bone; 4) craft business accessories such as handbags or wallets; 5) business of making starch feedstock citosan.

Abstract:

Energy is a very fundamental necessity in human life. Current energy usage is highly dependent on the surrounding environment. Especially in remote areas, which require simple energy instruments such as batteries or fuel cells. The Fuel cell is an energy instrument that transfers electricity from a rechargeable source using external materials. Microbial Fuel Cell (MFC) is an alternative form of environmentally friendly energy that is commonly used as a source of energy in the future. MFC is an energy instrument that can convert chemical energy into electrical energy through catalytic reactions by utilizing microorganisms. Plant waste tofu and fishery waste is a waste that contains a lot of carbohydrates, proteins, and fats that usually cause heavy pollution to the waters. By utilizing the liquid waste itself is one way of solving problems in the environment and lack of energy by using the MFC system. For the experiment, this time aimed to compare the electrical energy generated between waste plant tofu and sewage fisheries. In a strong MFC experiment current on plant waste knows an increase as much as 1.47% of fisheries waste, while for voltages in the trial MFC waste fisheries have increased by 1.19% from tofu plant waste.

Abstract:

Abstract Chlorella sp. can growth in various media that contains enough nutrients, such as N, P, K and other micro-elements. Growth of Chlorella sp. requires the availability of nutrients that can be derived from the chemical decomposition and solution results or waste. Liquid fertilizer waste sardinella fish (Sardinella sp.) is wasted and without any economic value is a new breakthrough in utilizing any part in the fisheries sector so as to maximize the potential of fisheries. Utilization of this, one of which is to make Liquid fertilizer waste sardinella fish (Sardinella sp.) which serve as nutrients for the growth of Chlorella sp. with 7 treatments and repeated 3 times. The treatment used is the doses of liquid fertilizer waste sardinella fish (Sardinella sp.) differently, namely A (0,25 ml/L), B (0,5 ml/L), C (1,75 ml/L), D (1 ml/L), E (1,25 ml/L), F (1,5 ml/L), G (Walne), H (without fertilizer). The results showed that the addition of liquid fertilizer waste sardinella fish (Sardinella sp.) with different doses give a real impact (p<0,05) for growth population of Chlorella sp. The best doses of liquid fertilizer waste sardinella fish (Sardinella sp.) for the population growth rate of Chlorella sp. was 0.75 ml / L is the treatment of C with the highest population of 3500x103 cells / ml.

Abstract:

Fisheries management has evolved in Malawi from a traditional system to a centralized regime and lately to co-management fisheries systems, although, success stories about sustainability of the fishery resources are few. Open access nature of fisheries resources has posed a challenge to management regimes. Resource over exploitation has continued in a majority of fisheries worsened by large stretches of the shoreline manned by a single fisheries field staff, and limited capacity by DoF to monitor and manage the fishery. However, isolated localities have upheld management styles that have facilitated sustainable exploitation. Mbenji Island fishery ‘managers’ have ensured high compliance to fisheries rules and regulations among fishers through strict enforcement and maintained abundant fish stocks amid visibly declining levels of fish in vast localities of Lake Malawi and other water bodies in Malawi. There is,therefore, need to take the Mbenji Island success story to other fishing communities to learn from their fisheries management strategies. Information Communication Technology (ICT) as a powerful means in mobilizing communities to take charge of their own development should support ‘best practices’ and offer fishing communities access to the same type of services and advantages. If appropriately applied,ICT can provide for real-time monitoring of fisheries resources as fishers alarm law enforcers to move in at appropriate times. Fishers also strike deals on mobile phones for the day's catch even before landing at shore. This reduces post-harvest waste from delayed handling of fish. Computers have been used for data management, storage and analysis as well as accessing internet services. Studies have shown commonalities in fisher communities in terms of socio-economic and cultural characteristics. On the basis of such an advantage, more could be shared among such communities. Management success can be adopted by other communities of fishers through use of ICT such as radio programs (supplemented by phone-in sessions) undertaken by local-level resource users. These programs provide locally available information and knowledge on best practices aimed at sustainability with means within communities. This encourages community members in other localities to come together to seek the way forward on the basis of lessons from successful communities aired on local radio stations (both community or national radio stations). It is easier to adopt practices that have worked in near vicinities. After all,what is currently called co-management is seemingly based on indigenous knowledge of fishers and other resource users. Mbenji Island is one of the custodians of ICT option in small-scale fisheries management of Lake Malawi. Information Communication Technology provides opportunity for both the Malawi Department of Fisheries (DoF) and fishers with information about fisher community activities including catch and market regardless of distance.

Abstract:

In recent years, the problem of food waste has attracted considerable interest from food producers, processors, retailers, and consumers alike. Food waste is considered not only a sustainability problem related to food security, but also an economic problem since it directly impacts the profitability of the whole food supply chain. In developed countries, consumers are one of the main contributors to food waste and ultimately pay for all wastes produced throughout the food supply chain. To secure food and reduce food waste, it is essential to have a comprehensive understanding of the various sources of food wastes throughout the food supply chain. The present review examines various reports currently in the literature and quantifies waste levels and examines the trends in wastage for various food sectors such as fruit and vegetable, fisheries, meat and poultry, grain, milk, and dairy. Factors contributing to food waste, effective cost/benefit food waste utilisation methods, sustainability and environment considerations, and public acceptance are identified as hurdles in preventing large-scale food waste processing. Thus, we highlight the need for further research to identify and report food waste so that government regulators and food supply chain stakeholders can actively develop effective waste utilisation practices.

Abstract:

Critical land area in Indonesia was recorded 23.25 million ha in 2000, and increased to 77.8 million ha in 2007, efforts are needed to optimize it. However, the existence of agricultural waste, livestock waste and sewage abundant fishery potential to increase soil fertility has not been utilized to the maximum. This study aimed to determine the macro nutrient content available in waste after the fermentation process. This research is an experimental research conducted in a laboratory to find out the content of: N, P, K, C / N ratio. The method for making liquid organic fertilizer is fermentation for one month using EM4 effective microorganisms, then analyzed using Spectrometry and Titrimetry Kjeldahl. The results showed that the highest N content was in bio urine fermentation (0.126%), fish waste (0.035%) and mixed waste (0.028%); The highest P was found in cattle rumen (7.239 mg / L), bio urine (5.234 mg / L), and seaweed (4.689 mg / L), and highest K was found in fruit waste (7, 801 mg / L). The highest C / N ratio was found in seaweed (55,643%) and fruit waste (27,857%). The conclusion is that agricultural waste, livestock waste, and fisheries waste after 1 month of fermentation contain adequate nutrients for optimizing critical land.

Abstract Frid, C. L. J., and Paramor, O. A. L. 2012. Feeding the world: what role for fisheries? – ICES Journal of Marine Science, 69: 145–150. Fisheries (wild capture and aquaculture) deliver more than 110 million tonnes of food and around 15% of the dietary protein to the 7 billion people currently living on the planet. With the global population expected to peak at 9 billion by 2050, and >80% of global fish stocks currently fully or overexploited (and aquaculture is at least in part dependent on capture fisheries), the contribution of fisheries looks set to decline. The challenge is therefore determining how better management, an ecosystem perspective, and more efficient utilization of fisheries waste can support fisheries products continuing to contribute significantly to “feeding the world” up to and beyond the population peak.

Abstract:

AbstractInteractions between seabirds and commercial fishing activities have been well documented but little information is available regarding the impacts of more traditional fishing practices on seabird populations. We interviewed fishermen, administered questionnaires, and made field-based observations to determine the extent to which artisanal fisheries interact with and affect seabirds in the fjords and channels of the Chonos archipelago in southern Chile. Our surveys indicated a positive perception of seabirds as useful indicators of marine productivity and in their role scavenging fish waste and discards associated with fishing operations. However, the surveys also revealed that fishermen routinely establish seasonal camps for collecting seabird eggs and adults for food or bait and introduce feral predators to seabird breeding colonies on islands. Understanding the traditional practices of fishermen is critical for the future of community-based conservation of the region's marine resources and biodiversity.

Abstract:

This study aims to (1) analyze the authority of actors to access (control) rights-based marine resources, (2) to analyze the power of actors to access marine resources based on structures and relational resources. This Research was conducted at seawater of Palabuhanratu, Sukabumi, West Java. We use qualitative methods in the present study. The results showed that among local fishers, immigrant fishers (settle), outside fishers (not settle), and managers of the thermal power station (PLTU) have different interests in using marine resources. The Fishers groups have an interest in utilizing marine and fisheries resources (including fishing areas and fish), while PLTU managers have interests in the construction of power plants, barge transportation (coal transportation), development of dams, construction of barge ship ports that buy 3 million seas. The approved PLTU activities must access fisheries against marine resources, coupled with the indication of PLTU waste pollution that harms fishers. The results of the analysis of rights-based licensing for each actor have legislation that is built on official law. The relations of the power's actors to access marine resources based on the structures and relational was held through types of power, i.e., technology, capital, markets, knowledge, authority, social identity and social relationships.

Abstract:

Following the growth of the global population and the subsequent rapid increase in urbanization and industrialization, the fisheries and aquaculture production has seen a massive increase driven mainly by the development of fishing technologies. Accordingly, a remarkable increase in the amount of fish waste has been produced around the world; it has been estimated that about two-thirds of the total amount of fish is discarded as waste, creating huge economic and environmental concerns. For this reason, the disposal and recycling of these wastes has become a key issue to be resolved. With the growing attention of the circular economy, the exploitation of underused or discarded marine material can represent a sustainable strategy for the realization of a circular bioeconomy, with the production of materials with high added value. In this study, we underline the enormous role that fish waste can have in the socio-economic sector. This review presents the different compounds with high commercial value obtained by fish byproducts, including collagen, enzymes, and bioactive peptides, and lists their possible applications in different fields.

Abstract:

The Maracanaú WSP in Fortaleza, the largest pond system in northeast Brazil, treating combined domestic and industrial (mainly textile) wastewater, was studied during a 13 month period. BOD and COD removal was 93 and 84%, respectively. On average the algal biomass represented 58% of total BOD in the ponds (3.3 mg per 100 μg of chlorophyll a). Ammonia removal was high (95%) but phosphorus was poor (20%). Faecal coliform removal reached 6 log10 units and the count in the final effluent was ≤1,000 cells/100 ml. This performance was expected since the hydraulic retention time was greater than 100 days. Informal fish culture of Nile tilapia (Oreochromis niloticus) was practised by local fishermen in the secondary and tertiary maturation ponds with yields of 1,706 and 241 kg/ha, year, respectively. Capture per unit efforts (CPUE) were similar to those found in local inland fisheries. However fish biometry showed a poorly attractive product for commercial purposes, with mean individual fish weights of less than 100 g.

Abstract:

Organic waste is the largest composition of waste generated by the people of Indonesia, which is around 50-60%. This type of waste, especially food waste, is easy to smell if it is stored for too long so that it has the potential to pollute the environment. On the other hand, organic waste has good nutrients that can be generated, including through BSF (Black Soldier Fly) maggot bioconversion treatment. The BSF maggot bioconversion method is a method of processing organic waste which is carried out by converting organic matter into other products that are useful and have added value by utilizing biological processes from microorganisms and enzymes. Organic waste treatment with this method is generally carried out on a community-based basis and is integrated with the development of agriculture, fisheries and animal husbandry, because maggot cultivation produces commodities of economic value such as compost and maggot larvae. Compost contains very good nutrients so that it can be used for organic farming and maggot contains high protein that can be used for animal feed and fisheries. The implementation of this program was piloted in the boarding school community, namely the Az-Zakaria Islamic Boarding School which is managed by the Az-Zakaria Islamic Education Foundation (YPI) in Sindangbarang Village, Jalaksana District, Kuningan Regency. The result of this implementation is the formation of a new group of entrepreneurs engaged in the cultivation and utilization of BSF maggots.

Abstract:

Worldwide fisheries generate large volumes of fishery waste and it is often assumed that this additional food is beneficial to populations of marine top-predators. We challenge this concept via a detailed study of foraging Cape gannets Morus capensis and of their feeding environment in the Benguela upwelling zone. The natural prey of Cape gannets (pelagic fishes) is depleted and birds now feed extensively on fishery wastes. These are beneficial to non-breeding birds, which show reduced feeding effort and high survival. By contrast, breeding gannets double their diving effort in an attempt to provision their chicks predominantly with high-quality, live pelagic fishes. Owing to a scarcity of this resource, they fail and most chicks die. Our study supports the junk-food hypothesis for Cape gannets since it shows that non-breeding birds can survive when complementing their diet with fishery wastes, but that they struggle to reproduce if live prey is scarce. This is due to the negative impact of low-quality fishery wastes on the growth patterns of gannet chicks. Marine management policies should not assume that fishery waste is generally beneficial to scavenging seabirds and that an abundance of this artificial resource will automatically inflate their populations.

Nelayan mengetahui sumberdaya laut secara rinci, juga lingkungan mereka dan aktifitas penangkapan yang mereka lalukan, dan pengetahuan ini jarang dikoleksi secara sistimatik. Penelitian ini dilakukan untuk menguji persepsi nelayan terhadap perubahan hasil tangkapan dan penyebabnya. Kami mewawancarai nelayan pantai Haive Besar dengan menggunakan kuisioner yang sifatnya semi terstruktur. Informasi pribadi nelayan seperti umur dan pengalaman menangkap ikan, aktifitas penangkapan seperti alat yang digunakan dan daerah penangkapan, serta pengetahuan mereka tentang perubahan ekosistem menjadi topik pertanyaan di dalam kuisioner. Nelayan dengan usia karir menengah (21-35 tahun) lebih banyak dibandingkan nelayan usia karir muda dan karir tua. Nelayan mendeteksi perubahan pada ekosistem daerah penangkapan mereka seperti banyaknya sampah, limbah minyak, rusak dan berkurangnya habitat karang dan lamun serta kekeruhan. Dampak yang nelayan rasakan adalah hasil tangkapan yang semakin berkurang bahkan tidak ada lagi. Persepsi nelayan terhadap perubahan ekosistem dan hasil tangkapan mereka menjadi dasar bagi penelitian selanjutnya seperti fisheries assessment. FISHERS’ PROFILE AND PERCEPTION ON THE SHIFTING OF CATCH ON THE COAST OF AMBON BAY. Fishers have detailed knowledge of their resources, their environment, and their fishing practices that is rarely systematically collected. This study was undertaken to examine perceptions of fishers on the shifting of catch and the occasion of the changing. We conducted an interview with coastal Hative Besar fishers using a semi-structured questioner. Fishers’ profiles such as age and years at fishery, gears and fishing grounds was one part of the questions. Other part was fishers’ ecological knowledge focused on environmental condition and shifting catch. More fishers with middle career (21-35 year in fishery) than young and old careers were interviewed. Environmental changes included waste in the water, oil, corals and seagrasses degradation, and turbidity affected the catch of fishers. Fish became difficult to be found. We learn from this study that fishers’ perception is an important tool for further fisheries assessment study.

National park has a beach about 48 km long with a stretch of coral reef 5-10 meters out to sea into creating high productivity in these waters, especially various types of reef fish such as grouper. The highest numbers of catches are in district Banyuputih where the glaze was located 1734.65 tons in 2011, followed by the District Besuki with catches of 964.20 tons. In general activities in the nickel smelting are result some waste such as heavy metals such as Cu, Fe, Zn, Mn, waste heat from cooling water and wastewater canal SO2. Heavy metals and waste heatare potential adverse impact on the coral reefs, fish capture fisheries and the other marine commodities. While waste SO2 causes acid rain damage potential plant of agriculture, fisheries not only in the park but it could be damaging crops in the National Park that have an effect on the scenery, the number of visitors, and reduce operating revenues derived from the national park. We use the concept of gaming between actors to estimate the associated policy goal of this smelter. As for observing the behavior of the system over the next 10-30 years used the dynamics modeling system with 3 scenarios. Optimist scenario(there is Green smelter), excisting scenario(Condition without smelter) and pessimist scenario(there is non green smelter).

Abstract:

The study explored fisherfolk’s perception and attitude in regard to solid waste disposal and the implications of these for public health, aquatic resources, and sustainable development (SD) in a Ghanaian fishing community. Qualitative data were obtained from 37 purposively targeted participants comprising 34 fisherfolk, an environmental health expert, a water and sanitation expert, and a fisheries and aquatic sciences expert through in-depth interviews and focus group discussions. Data were analysed thematically guided by the most significant stories. While the fisherfolk perceived waste as useless and a nuisance, the experts saw it as a nuisance and/or resource. The fisherfolk did not sort their waste in line with best practices, nor were they willing to pay for waste collection services, citing poverty as the main reason. While most fisherfolk disposed of their waste into bins as approved, others did so onto the street, into the drains, lagoon, and sea. While the fisherfolk were aware that indiscriminate waste disposal led to diseases such as malaria and cholera, their perceptions of the effect of the same on aquatic resources were mixed. The fisherfolk’s conception and perception of waste led to attitudes, behaviours, and practices that polluted the environment (air, land, and water resources), resulting in public health challenges, a threat to navigation, fish population, and other biodiversity, which were inimical to livelihoods and sustainable development. The government and municipal authority should collaborate with the experts in environmental health, water and sanitation, fisheries and aquatic sciences, and traditional authorities to sensitise the fisherfolk on the sustainability implications of unapproved solid waste disposal practices to change their attitude for the better. They should also provide more waste disposal infrastructure and enforce the laws to ensure compliance with best practice for sustainable development. The study supports the compatibility and mutuality between Sustainable Development (SDG) 6 on water, sanitation, and hygiene and SDG 14 regarding sustainable use of the oceans, seas, and marine resources.

Abstract:

Many advantages of burden wastes which adversely impact to the environment in the form of solid waste. Green shellfish wastes are used for resources of chitosan. The aim of this works is to identify the effectiveness of chitosan application into 2 kinds of moist foods; wet noodles and meatballs. The concentration of chitosan are 0%, 0.5%, 1%, 1.5%, and 2%. The samples are immersed for 0,15, 30, 45, and 60 minutes. The study has found the water content of chitin is 8.31% and chitosan is 6.83%. The degree of deacetylation of chitin is 37.81% and chitosan is 82%. The best concentration of chitosan for wet noodle is 1.5% -2% with the immersion of 45 -60 minutes, and for meatballs is 1.5%-2% with the immersion of 15 minutes. The organoleptic test, on day-3 noodle and meatball, is still in good condition. If no chitosan added the noodles sample is day-1 is in fair condition, while meatball should be consumed directly because in day-1 is becoming chewy with a sour taste, and on day-2 are overgrown with mushrooms.

Abstract:

This study analyzed the root causes of poverty in the cage fishing community at Limboto Lake; economic potentials; government programs related to poverty alleviation that has existed along with the causes of failure to exclude the cage fishing community from poverty puddles; and priority ideas from the fishing community that can overcome existing poverty puddles. Data collection was done through observation, interviews, focused group discussion, and literature review. The results showed that there are many aspects of the root causes of the poverty of fishing community at Limboto Lake coastal, namely policies that do not favor fishing community; low quality of human resources; the attitude of fast satisfied fishers; consumptive lifestyle; marketing of fish crops through intermediaries; and natural factors. Meanwhile, the real, local potentials are fisheries potential; crafts of water hyacinth based; lake tourism; the potential of water resources; and the potential for limestone as a raw material for cement. Several government programs related to poverty reduction failed to free the cage fishermen community from the puddle of poverty. Firstly; the program is project-oriented that emphasized the project administration rather than the target of releasing fishers from poverty; secondly, elite dominations, so that sure fishermen elites more enjoy the existing programs on behalf of their community. The priority idea of the fishing community to overcome existing problems is to increase knowledge and skills. Increasing utilization of lake biological resources; open access to domestic and international markets; developing opportunities for alternative economic activities around the lake area; the establishment of a local organization of lake lovers; processing domestic waste, and assisting the business of fish cultivation in Limboto Lake.

Abstract:

Food is wasted throughout the entire food supply chain—from agricultural production to the household level. This has negative impacts on natural resources and the environment. At the same time, food waste is undermining the global target of food security. In turn, reducing food waste can minimise the environmental effects of agriculture on climate, biodiversity, soils, water bodies and the atmosphere. All of this is reflected in the fact that food waste is subject to various legal acts of the European Union and that it is also a major subject in the new EU Farm to Fork Strategy from May 2020. Supported by an analysis of the diffuse empirical data on food waste, the purpose of this article is to analyse the current EU legislation on food waste and its reduction to answer the following research questions: How is food waste integrated into European policies? What is the impact of European legislation on food waste? Is European legislation sufficient to trigger not only food waste reduction but also comprehensive changes in the agricultural and food sector to support global climate and environmental targets as set in the Paris Agreement and the Convention on Biological Diversity? Which instruments are the most suitable to do so? Methodologically, a qualitative governance analysis is applied. It is found that relevant legal acts for governing food waste include circular economy and waste law, the Common Agricultural Policy and the Common Fisheries Policy as well as food law, while international environmental targets serve as an overarching measure for governance analysis. The legal analysis shows that existing legislation lacks steering effect to significantly reduce food waste. To overcome current governance problems, the article introduces economic policy instruments. It is concluded that quantity control focusing on overarching parameters such as fossil fuels or animal-derived products has not only the potential to reduce food waste by increasing food prices but can also address the multiple interlinked environmental challenges of the agricultural and food sector.

Abstract:

Asahan Regency is a national strategic area because it has superior sectors such as plantation, marine, agriculture, fisheries and industry. This caused a lot of waste to arise in Asahan Regency. One of the efforts made by the Department of Environment to reduce the volume of waste is to make the Waste Bank an innovative program of community-based waste management. The Waste Bank at the Environmental Service was given the name "Srikandi" which was still less effective and efficient. Because at this time the process is done manually. For that we need to design a system by implementing the waterfall method, which is a sequential software development process, where progress is seen as continuously flowing down (such as waterfalls) through the phases of planning, modeling, implementation (construction), and testing. Hunger by implementing the waterfall method and the C2C e-commerce model in designing and building the E-Recycle Bank system. As a result, the system will make it easier for "Srikandi" Waste Bank officers to manage waste data so as to produce more effective and efficient data, besides that it can also be used as a container for the promotion of waste recycling products for the Asahan Regency

Abstract:

On April 13, 2021, the Japanese government officially decided to release Fukushima Daiichi Nuclear Power Plant into the sea, which is harmful to the marine environment. Japan is adjacent to the East China Sea. The East China Sea is China’s main marine ecological aquaculture area. The discharge of nuclear waste water in Japan will inevitably have an impact on the status of China’s aquatic product industry and aquatic product trade. Based on the current situation of China’s aquatic products industry and the competitiveness of China’s aquatic products in foreign trade, this paper predicts the impact of Japan’s nuclear waste water discharge on China’s aquatic products trade. Therefore, China should actively use technological innovation, regulatory upgrading, optimization of fisheries technology and other policies in advance to deal with the impact of this nuclear waste water discharge.

Abstract:

Abstract Aquaculture is currently the fastest growing food-producing sector in the world. The growth of this industry has been rapid for the last 25 years, however, aquaculture still relies heavily on feed input from wild capture fisheries. Landings in wild capture fisheries have been stagnant for the last two decades; therefore, new alternatives for conventional fish meal and fish oil need to be found. In this review, various alternatives are described and their advantages and disadvantages are evaluated. Single cell oils (SCO) and single cell proteins (SCP) produced by microorganisms are recognized as the alternative with the most potential for replacing fish meal and fish oil in aquacultures. However, production costs of SCOs and SCPsare still higher than production costs of Omega-3 rich oils from other sources (wild capture, plant derived oils and genetically modified plants); therefore, currently used substrates need to be replaced with cheaper agriculture and industrial biomass residues applicable for microbial fermentation. In order to evaluate various biodegradable residues and find the most suitable ones for SCO and SCP production, methods analysing resource availability are reviewed.

Abstract:

The potential wealth of marine resources such as marine fisheries resources is owned by Indonesia. The wealth of marine resources has not been utilized and managed optimally. Today, there are many businesses driven in various fields. The business of building floor crafts from sea shells (anadara grandis) can be pioneered into one form of business. Buton Regency is an archipelago, more than 80% of its territory consists of sea. During this time, shellfish cultivated by fishermen only used the meat, while the shell removed and became waste. This research aims to utilize shell waste into floor material. The method used in this research was exploration method. The data began with the selection of materials, work tools, and stages of manufacture. Information from various sources is captured and interpreted into a creative idea. The process of analysis was done qualitatively, so it was obtained and raised the shape of the floor. This study concludes that the use of waste shellfish shells into composite floor material is done in three stages. In the first stage, prepared work tools such as glass molds, measuring cups, stirring spoons, brushes, flooring boards, measuring tools, hammers, cutter knives, sandpaper and plastic. The second stage is prepared work materials such as shells, hardener, resin oil, and mirror glass. The third stage is made of floor like shell stage filled with resin oil; The printed floor stage is like smearing a glass mirror on the mold, the resin oil is mixed with hardener, the composite mixture is poured into the mold, the shells are placed in the mold, the shells are poured again with resin oil, and hardener; Stage of removing from glass mold and; finally the floor is given the ballast.

Abstract:

The potential of fishery resources in Gorontalo is quite abundant because of its strategic geographical position bordering Tomini bay. Gorontalo, especially in the Dungingi District, is one of the regions with promising potential fisheries resources where fishery application activities are not only focused on fish cultivation but also processing fishery products. However, people's understanding of fish processing that can only be obtained from their meat makes the community's income in the Libuo Village, Dungingi District Gorontalo City tend to be unstable. The Libuo community as fishery product processing actors need to be given an understanding of the potential and diversification of fishery products that can be produced from by-products that can be obtained from bones, scales, stomach contents, heads, and fish skins so that the application of zero waste can be implemented. Also, as an effort to increase public understanding related to the shelf life of fishery products which tends to be fast, the use of carrageenan as an alternative to edible coatings needs to be introduced to the community as a form of food safety of fishery products. Thus the benefits will be gained from increasing the added value of fisheries and a better level of food safety.

Abstract:

Water quality, particularly coastal areas, is systematically tropogenic. The decline in water quality is caused by industrial waste pollution, soil erosion carried by the river, and the depletion of mangrove areas. The decrease of water quality can affect the fishery cultivation activities that exist in the region. It also affects the quality of the cultivated fish. Fish cultivated in ponds with poor water quality can be harmful to the health of the people who consume the fish. One effort to manage the feasibility of pond waters is by identifying the quality. The purpose of this research is to know the profile of pond water quality and to know the diversity potential of aquaculture. Based on the nature of the problem this research is a field research, while the purpose of this study is descriptive and explanatory research. The method used in this research is research by using survey method. Aquatic profile results are essential to improve the quality and quantity of Fisheries, especially in diversifying fisheries.
