Abstract:

Indonesia is a beautiful archipelago country. It has many habitat type and ecosystem. The most interesting area is karst. By its special characteristics like high concentration of calcium (Ca), makes karst area has a specific and uniquely ecosystem. Gunungsewu is the largest karst area in Indonesia. The surface ecosystem of karst (eksokarst) in Indonesia is very dry, however we can find Leopard (Panthera pardus L), especially in Southern part of Karst Gunungsewu. That is why we are interested to study about it. In this study, we use observation and interview method. From the temporally result (research still on progress), we know that in Purwodadi, Tepus area live two sub-species of Leopards, those are Spotted Leopard (Panthera pardus pardus) and Javanese Black Leopard (Panthera pardus melas) with porcupine (Hystrix javanica), squirrel (Caloscurus notatus), Mongoose (Paradoxurus hermaphroditus), and other small mammals and some birds as their prey. In some cases, we find Leopard eats the dead human body but they rarely eat cattle although it takes in the middle of the farms. The habitat of Leopard was fragmented. Now they only life in five fragmented part of karst Gunungsewu and their habitat degrade slowly from year to year. From the results, we can conclude that conservation in Karst of Gunungsewu especially in Purwodadi, Tepus, Gunungkidul is badly needed. It must be done soon because Leopard becomes extinct. We can use local wisdom to conserve it because it has proven can make a good interaction between human and Leopards in their habitat. Keyword: predator, tropical, karst, Gunungsewu

Abstract:

Siklon Tropis Savannah melewati Daerah Istimewa Yogyakarta pada tanggal 17 Maret 2019. Curah hujan yang disebabkan oleh Siklon Tropis Savannah terekam pada stasiun Geofisika badan meteorologi, klimatologi dan Geofisika (BMKG) Yogyakarta sebesar 170,6 mm/hari dan terekam pada Stasiun Cuaca Beton milik Kelompok Studi Karst Fakultas Geografi Universitas Gadjah Mada sebesar 78,3 mm/hari. Curah hujan menunjukkan bahwa siklon tropis ini menyebabkan terjadinya hujan ekstrim. Siklon Tropis Savannah menyebabkan bencana banjir di beberapa wilayah Daerah Istimewa Yogyakarta salah satunya terjadi di Karst Window Kalinongko, Kawasan Karst Gunungsewu, Kabupaten Gunungkidul. Karst Window Kalinongko terdampak banjir dari meluapnya sungai bawah tanah. Proses terjadinya banjir di Karst Window Kalinongko disebabkan oleh aliran air yang melebihi kapasitas pengaliran dari lorong konduit pada sungai bawah tanah. Sistem konduit yang penuh kemudian meluap ke permukaan dan menggenang pada bagian dolin di sekitar Karst Window Kalinongko. Waktu surut banjir airtanah di Karst Window Kalinongko adalah selama 10 hari. Banjir Siklon Tropis Savannah yang menggenang memiliki volume sebesar 4.894.258 m3, luasan area terdampak seluas 13.723 m2, dan ketinggian genangan 6 meter. Dampak genangan banjir airtanah yang disebabkan Siklon Tropis Savannah di Karst Window Kalinongko merendam lahan sawah seluas 10.586 m2 dan perkebunan seluas 3.137 m2.

Abstract:

Karst area is highly susceptible to changes to climate parameters. One of the parameters is rainfall variability. In addition to shaping the condition of water resources, rainfall in the Gunung Sewu karst area determines the nature of crop and livestock of the agriculture sectors―the local population's main economic activities, warranting the significance of the rainfall variability studies. Rainfall variability in karst areas also affects disaster conditions such as drought and floods. However, due to insufficient meteorological data in quality and quantity, there has been no rainfall variability studies conducted in this locality. The research intended to analyze rainfall variability in the Gunung Sewu karst area in 1979‒2013 by utilizing rainfall predictions from satellite images that many scholars had tested in different locations and recognized as having good quality. In the analysis, mean monthly rainfall was calculated, and the trends of annual rainfall and average rainfall intensity, dry and rainy seasons, the number of rainy days, and the effect of ENSO (El Niño Southern Oscillation) on rainfall were analyzed. The research data were 35 years of daily rainfall records derived from the National Centers for Environmental Prediction (NCEP) Climate Forecast System Reanalysis (CFSR). The analysis results showed that the mean rainfall, number of rainy days, and rainfall intensity had an increasing trend. Also, El Niño quantitatively influenced the rain in the Gunung Kidul karst area.

Abstract:

The Maros Karst is known for having a unique geomorphological structure with a diversity of endemic flora and fauna. The hydrology of this karst area is generally dominated by underground rivers with various freshwater ecosystems, which are generally dominated by endemic fish typical to Sulawesi. This study aims at identifying endemic fish of Maros Karst rivers using morphological and phylogenetic analysis as the baseline for further endemic fish conservation. Morphological analysis was done by comparing fish samples’ morphological characteristics with those from fish taxonomy references. Phylogenetic analysis was carried out using mitochondrial DNA (mtDNA) analysis with the target gene Cytochrome C oxidase 1 (CO1). The results showed there are five endemic fish species from four families and three orders from the Maros Karst area with a genetic distance value between 0.0 to 0.275. These species make particular adaptations both morphologically and genetically to the karst ecosystem. However, it is necessary to understand the evolution of these fishes to establish effective conservation measures. Therefore, it is necessary to have a management strategy to ensure the sustainability of endemic fish populations and as well as the sustainability of the karst ecosystem as a whole. © 2021 Friends Science Publishers

Abstract:

Indonesia is estimated to have 14,5 million hectares of karst areas. The characteristic of karst vegetation is specific, one of which is the dominance of small trees. With all of the potency, their vegetation acts as a significant carbon sequester and store it in biomass. This study aims to estimate and discuss biomass estimation in the karst forest within the Nature Recreational Park of Beriat, a protected area in South Sorong, West Papua. A total of 28 plots were made in the forest using the purposive random sampling method. Tree biomass (DBH ≥10 cm) was estimated using five different allometric equations. The results showed that the biomass was estimated at ca. 264 Mg ha-1 (95 % CI: 135-454 Mg ha-1). While small trees (DBH 10 – 30 cm) only contribute 30 % of the total biomass, about 38 % of the biomass is the contribution of large trees (DBH >50 cm), where Pometia pinnata contributes ca. 39 % of the biomass at plot-level. The use of various allometric equations results in different biomass estimates and biases with deviations ranged from -14.78 % to +17.02 % compared to the reference equation. Therefore, the selection of allometric equations used must be considered carefully to reduce uncertainties in biomass estimation.

Abstract:

Karst zoning and channel aquifers in the karst basin at Sendang Biru Beach, Tambak Rejo Village have been investigated. Sendang Biru Beach has a cave appearance as a karst morphological feature and is composed of limestone. Seasonal karst water sources come from springs, surface runoff, underground rivers, channels in valleys, basins, and slopes that often experience drought. The purpose of this study is to identify the presence of karst aquifers and karstification zones that are prone to damage or disasters in the karst environment. The method used is a geophysical combination of Electrical Resistivity Tomography (ERT), Induced Polarization (IP), and Self Potential (SP). The results showed that the eastern part's karstification zone was characterized by moderate to high resistivity and a chargeability zone with a moderate to high range. In addition, the existence of karst aquifer channels in the anomalous zone of low resistivity, high chargeability, and negative natural potential. This zone is located in the Qas Formation, with the water flowing from west to east and from west to south. The inundated karst aquifer that spreads in a circular pattern with different depths interspersed by limestone cracks causes a heterogeneous karstification process.

Abstract:

Tropical Cyclone Cempaka occurred on November 27, 2017 in the Indian Ocean, just south of Central Java. This incident induced high rainfall leading to flash floods in the southern part of Central Java, including Gunungsewu Karst Area. The highest rainfall recorded on November 28, 2017, in this area was 239 mm/day (Automatic Rainfall Recorder/ARR Station in Pindul Cave) and 341 mm/day (ARR Station in Tepus). The extreme rainfall also caused groundwater flood in Ngreneng Karst Window. This study aimed to analyze the mechanism of this flood. The results of the analysis showed that it was caused by water filling up the conduit passage in the entire Bribin-Baron underground river system. The flow of the conduit pushed the diffuse flow into the surface fast, and the water that came out of Ngreneng Karst Window was thereby clear. The inundation lasted for ten days and submerged up to 26.4 ha of the study area.

Abstract:

Global warming is a common problem that occurs in all parts of the world that triggers significant climate changes such as temperature increases, humidity changes, natural disasters, and can cause the extinction of flora and fauna, one of which is the swallow in Ciampea Karst, which has been damaged so that uninhabitable. In addition, the exploitation of limestone caves by humans causes swallows to feel uncomfortable and the need for artificial habitats. The goal is that the swallow's need for replacement habitat is fulfilled so that the Ciampea Karst ecosystem is not disturbed. The resulting architectural form is a technology-based captivity that takes swallows as the main subject of the project. The method used begins with the phenomenon and urgency of swallows that occur in Ciampea Karst area. Then analyzed and generated ideas in the form of captivity. However, it is not only limited to captivity, there is also an interaction space for humans in the form of swallow galleries, so that visitors can see the swallow's life. The overall shape of the building is based on an analysis study of the shape of the swallow's flying movement, so that the building adapts many forms of arches that are flexible in accordance with the swallow's daily activities. For the breeding method, it begins by using adaptation techniques first, namely by breeding the seriti bird that takes care of swallow eggs taken from the limestone caves of the Ciampea Karst. In addition to methods in design, the use of technology in building materials, especially in captivity and galleries, also uses natural materials such as natural exposed wood and brick walls. So, to show the side 'beyond ecology', it is not only limited to ecology in the use of materials, but there is an indirect interaction space between humans and swallows that functions to fight against human anthropocentric attitudes, while helping humans to feel the swallow's life in an architectural building.

AbstrakPemanasan global merupakan permasalahan umum yang terjadi di seluruh belahan dunia yang memicu terjadinya perubahan iklim yang cukup signifikan seperti kenaikan suhu, perubahan kelembaban, bencana alam, dan dapat menyebabkan kepunahan flora dan fauna, salah satunya burung walet di Karst Ciampea, yang sudah mengalami kerusakan sehingga tidak layak huni. Selain itu, eksploitasi gua kapur oleh manusia menyebabkan walet merasa tidak nyaman dan diperlukannya habitat buatan. Tujuannya agar kebutuhan walet akan habitat pengganti terpenuhi sehingga ekosistem Karst Ciampea tidak terganggu. Bentuk arsitektur yang dihasilkan berupa penangkaran berbasis teknologi yang mengambil walet sebagai subjek utama proyek. Metode yang digunakan berawal dari fenomena dan urgensi walet yang terjadi di kawasan Karst Ciampea. Kemudian dianalisa dan dihasilkan ide berupa penangkaran. Tetapi, tidak hanya berbatas pada penangkaran, tersedia juga ruang interaksi untuk menusia yang berupa galeri-galeri walet, sehingga pengunjung dapat memandang kehidupan walet. Bentuk bangunan keseluruhan didasarkan pada studi analisa bentuk gerakan terbang walet, sehingga bangunan mengadaptasi banyak bentuk lengkungan yang leluasa sesuai dengan aktivitas keseharian walet. Untuk metode penangkaran, diawali dengan menggunakan teknik adaptasi terlebih dahulu, yaitu dengan menangkarkan burung seriti yang mengasuh telur walet yang diambil dari gua-gua kapur Karst Ciampea. Selain metode dalam perancangan, penggunaan teknologi pada material bangunan terutama penangkaran dan galeri juga banyak menggunakan bahan alami seperti kayu dan dinding bata ekspos yang bersifat alami. Sehingga, untuk menampilkan sisi ‘melampaui ekologi’, tidak hanya terbatas pada ekologi dalam penggunaan material, tetapi terdapat ruang interaksi yang tidak langsung antara manusia dengan walet berfungsi untuk melawan sikap antroposentris manusia, sekaligus membantu manusia untuk turut merasakan kehidupan walet dalam suatu bangunan arsitektur.

Abstract:

The definition of a karst drainage basin in the aquifer of the karst area is an absolute thing to do as a water resource management unit. This research aimed to characterize the hydrogeology of the Gunungsewu Karst Area in the upper reach of the Gremeng Karst Drainage Basin. For this purpose, it was divided into three stages, namely geological survey, speleological survey, and artificial tracer test. The results indicate that the area observed lies in two or more geological formations: Semilir Formation, composed of sandstone and tuff from the ancient volcano Wonodadi eruptions, and Wonosari Formation, in which carbonate rocks consisting of massive coral limestone and bedded chalky limestone predominate. In volcanic rocks, the surface rivers have developed into allogenic streams flowing from underlying beds exposed updip. The contact between the two different formations results in the formation of ponors and springs. The artificial tracer test revealed two underground river systems with single conduits controlled by the allogenic rivers and large slope gradients in the study area.

Abstract:

Analysis of groundwater availability for irrigation purposes pertains to not only quantity but also quality. The characteristics of groundwater quality essentially define crop productivity and determine whether or not crops can grow. This research was designed to identify the suitability of karst groundwater for irrigation temporally (in one year), with an example of Gremeng Resurgence in Gunungsewu Karst Region, Indonesia. It drew on data on electrical conductivity and several major ions, such as potassium, magnesium, sodium, and calcium, by analyzing % sodium content (Na%), Sodium Adsorption Ratio (SAR), and groundwater suitability for irrigation using the Wilcox and USSL diagrams. These analyses revealed that the water quality observed varied by seasons owing to the effects of dilution by rain and water-rock interaction in the karst region. However, this temporal variation was not substantial so that the classes of groundwater suitability only ranged between good and excellent, and the salinity hazard levels differentiated into low until medium.

Abstract:

Abstract One of the poverty areas in Indonesia is in Gunungkidul district, an arid area in the karst mountain area. The scarcity of surface water is the main obstacle to economic development activities in the Karst Mountains of Gunungkidul, especially for agriculture and animal husbandry. The vulnerability of nature, agro-climate, and geographical conditions are not suitable for agricultural economic activities. The income of the agricultural community in the karst mountain area is minimal, which causes high poverty. The highly volatile rainfall in the region and extreme climate change can be destructive. Hence, poverty occurs in Gunungkidul, where dry land and Karst Mountains dominate geographical conditions exacerbate this condition. This study investigates the pattern of household expenditure and analyzes the factors that increase household income. This study applied descriptive analysis and income determination function. The results showed that more than half of household expenditure was for food needs. Non-farming activities have a high contribution to household income. Therefore, to increase household income, households must engage in off-farm jobs. The higher the household income, the food security will be sustained.

The growing public interest in travelling has become a different strength for the tourism industry currently. The existence of a person on a trip that can be shown on social media can be a force that indirectly becomes a promotional tool. The tourist village that is currently trending is a form of tourism which consists of natural tourism which is integrated with other tours, to provide a unique value compared to additional terms. The Karst area in Maros and Pangkep Regencies has the potential to be used as a tourist area, but currently, these karst areas have been widely used as raw material for the cement industry. One of the villages that has natural karst tourism in Maros Regency is the village of Botolempangan which has been planned by the village government as a tourism village because it has various unique natural resources that can become new income alternatives for the community, so it is essential to be developed as well as a reason to maintain the area. Karst which began to be eroded by industrial companies. The purpose of this study was to identify tourism potential and analyze the development strategy of the tourist village of Botolempangan. The research method used is observation, in-depth interviews and FGD. The analysis used is a descriptive qualitative analysis and SWOT analysis. Based on the results of the study, it shows that the village of Botolempangan has tourism potential in the form of natural karst tourism, cave tourism (leang), fisheries tourism, Sulawesi endemic monkeys, natural scenery, outbound, camping and educational tours. Based on the SWOT analysis, there are four strategies that can be carried out to develop the tourist village of Botolempangan, i.e. 1). The increased synergy between the government, universities and the community, especially managers in maximizing the supporting factors for the implementation of tourism villages 2). We are managing the Botolempangan karst area into a tourism village that is integrated with nature tourism, fisheries tourism, culinary tours and educational tours 3). Optimizing village budgets to improve tourist facilities and providing education for managers in supporting tourism 4). Increased promotions that prioritize the uniqueness of the region, facilities and the convenience of visiting through social media and partnerships with a local travel.

Abstract:

Understanding the stage of karst aquifer development (karstification) is of vital importance because this parameter can reflect the character of flow system release, from which relevant management patterns are derived. Master Recession Curve (MRC) construction is considered ideal for identifying at which stage karstification works because MRC relies on recession curves as its primary input. Recession curves are the most stable component of flow hydrographs in representing aquifer characteristics. The study focused on springs located in a karst hydrogeological subsystem, namely, Guntur Spring in the Panggang Hydrogeological Subsystem (Gunungsewu Karst Area). It was designed to determine (1) the flow characteristics and (2) the degree of karst aquifer development at Guntur Spring. It utilized a one-year flow hydrograph with a 30-minute logging interval as the main data. The flood hydrograph showed that a fissure system dominated the flow characteristics. Moreover, the MRC construction results indicated that the karstification level at Guntur Spring was 5.0, confirming the dominant fissure system and also signs of the recent development of conduit flows.

Abstract:

The Gunungsewu karst area is not only known for its unique landscape but also its recurring drought events. To meet the water supply, the local population utilizes several water potentials, namely doline pond, spring, and underground river. This study was designed to analyze the hydrogeological conditions of Mbangsri Cave, following its accidental discovery by the community at the end of 2018. The hydrogeological analysis was conducted by geological surveys, which consisted of rocks collection and structural measurements, cave mapping, and recharge area delineation based on remote sensing images acquired by unmanned aerial vehicles. The results showed that Mbangsri Cave, in the hydrogeological perspective, had low water resources potential. It is believed to be the result of (1) relatively small catchment area, (2) a fault in the southern part of Mbangsri Cave, creating a small groundwater basin, and (3) the thin epikarst layer, limiting the water storage.

Abstract:

Karst of Sangkulirang Mangkalihat is one of the greatest karst areas in Indonesia and has hundreds of caves. Some of those caves are located at Suaran Block, one of the main karst block at this karst. This paper aims to study the speleogenesis process, as the fundamental process on karst landscape and cave development in that area. Speleogenetic process can be examined from the shape of the cave passage using uniformitarianism approach. That principle creates speleomorphology as the study of cave passage form and the factors that affect it. The examination of the cave passages uses cave maps to see the form and direction of them. As the result, caves at Suaran Block are formed mainly driven by geological structures such as fault – fissures and bedding plane which is indicated by linear form of the cave passage and water flow which shows sinusoidal form of the cave passage. Some caves are shaped by the combination of geological structure and water flows make them have mixed-induced speleogenesis.

Abstract:

Trees are significant components of ecosystems built by several widespread species. For instance, Papua forest is known to comprise abiotic and biotic elements. Also, certain plants have grown in popularity to a point where they are discovered almost everywhere. The purpose of this study, therefore, was to investigate tree diversity, distribution, and the importance of conservation. Data were collected in four locations using a total of 24 sample plots spread across Idoor, Karst, Persemaian, and Torembi, where seven, four, seven, and five plots were allocated, respectively. These forests formed a mixed natural plantation comprising 76 species from 35 families. Furthermore, Idoor and Karst generated the highest species diversity and varied significantly compared to Persemaian, while Torembi showed similarities with the other three locations. This condition formed three ecosystem communities across Persemaian, Karst, Idoor, and Torembi. Also, the composition of the dominant species showed variations at the seedling and sapling levels believed to structure the understory, while the pole and tree levels characterized the overstory. The total species status was described as critically endangered (CR) of two species, vulnerable (VU) of six species, least concern (LC) of 28 species, and data deficient (DD) species. Therefore, location management is advised to not only pay significant attention in terms of economic benefits but also ecological, including the provisions for ex-situ and in-situ conservation to support sustainable forest management.

Abstract:

ABSTRAKSemen adalah serbuk atau tepung yang terbuat dari kapur dan material lainnya yang dipakai untuk membuat beton, merekatkan batu bata ataupun membuat tembok (Kamus Besar Bahasa Indonesia, 2008). Semen merupakan suatu bahan yang bersifat hidrolis, yaitu bahan yang akan mengalami proses pengerasan pada pencampurannya dengan air ataupun larutan asam. Bahan baku pembuatan semen antara lain : clinker/terak semen sebanyak 70% - 95% (hasil olahan pembakaran batu kapur, pasir silika, pasir besi dan tanah liat), gypsum 5% dan material tambahan lain (batu kapur, pozzolan, abu terbang dan lain- lain). Seiiring dengan peningkatan pembangunan insfrastruktur yang menjadi fokus Pemerintah saat ini, maka kebutuhan bahan baku bangunan khususnya semen mengalami peningkatan. Peningkatan kebutuhan ini membuat perusahaan semen meningkatkan produksi yang pada akhirnya juga akan mengurangi cadangan batugamping yang ada di alam. Sumber daya geologi terdiri atas sumber daya mineral, sumber daya energi, sumber daya air, dan bentang alam. Batugamping sebagai salah satu bahan baku dominan pembuatan semen merupakan sumber daya mineral dan bentang alam yang harus dilindungi. Kementerian Energi dan Sumber Daya Alam sejak tahun 2012 telah menerbitkan aturan terkait pemanfaatan dan perlindungan Kawasan Bentang Alam Karst (Permen ESDM N0. 17 Tahun 2012). Perlindungan terhadap Kawasan Bentang Alam Karst bertujuan untuk melindungi fungsinya sebagai pengatur alami tata air dan keunikan/nilai ilmiah dalam pengembangan ilmu pengetahuan. Sedangkan upaya pemanfaatan sebagai bahan galian maupun bahan baku industri diatur deliniasinya, sehingga tidak menganggu zona konservasi. Diharapkan dengan keluarnya Permen ESDM N0. 17 Tahun 2012 dapat menjadi solusi bagi pemanfaatan dan perlindungan Kawasan Bentang Alam Karst di Indonesia. Kata kunci: Sumber daya geologi, Semen, Kawasan Bentang Alam Karst ABSTRACTCement is powder made from lime and other materials used to make concrete, glue bricks or make walls (KBBI, 2008). Cement is a material that is hydraulic in nature, that is, a material which will undergo a hardening process in its mixing with water or acid solution. The raw materials for making cement include: clinker I slag of cement as much as 70% - 95% (the results of the combustion of limestone, silica sand, iron sand and clay), 5% gypsum and other additional materials (limestone, pozzolan, fly ash and etc). Along with the increase in infrastructure development which is the focus of the Government at this time, the need for building materials, especially cement, has increased. This increase in demand has made cement companies increase production, which in turn will also reduce the limestone reserves that exist in nature. Geological resources consist of mineral resources, energy resources, water resources, and landscapes. Limestone as one of the dominant raw materials for making cement is a mineral and landscape resource that must be protected.The Ministry of Energy and Natural Resources since 2012 has issued regulations relating to the use and protection of Karst Landscape Areas (Permen ESDM No. 17 of 2012). Protection of the Karst Landscape Area aims to protect its function as a natural regulator of the water system and its unique I scientific value in the development of science. Meanwhile, the delineation of utilization efforts as minerals and industrial raw materials is regulated so that it does not disturb the conservation zone. Expected with the regulations (Permen ESDM No. 17 of 2012) can be a solution for the use and protection of the Karst Landscape in Indonesia.

Abstract:

Flow moving slowly (infiltration), and known as steady flow or baseflow is the only supplier of water in underground flows in the form of karst fields during the dry season. Certainly, the character contribution of this flow plays a major role in supporting the supplier of clean water. Understanding related to the character of baseflow in detail has a very high urgency to be studied. This Research aims to do a temporal analysis of baseflow contributions on epikarst water springs in Gunungsewu Karst Area, Indonesia. The research takes place in Guntur Springs that occupy the hydrogeological subsystem. Data used in this Research includes flow data from Guntur Springs for one year. The method used in this Research is automated base flow separation by digital filtering. Results of the analysis show that baseflow contribution in Guntur Springs are between 79.57% and 93.96%.

Abstract:

Air pollution is a major environmental problem in Indonesia. Potentially toxic elements (PTEs) which bounded to particulate matter (PM) samples were collected from Maros karst area, the second largest karst in the world. The seasonal levels of PTEs and ecological risk assessment were used to investigate the pollution levels near the residential areas using pollution load index (PLI) and potential ecological risk index (PERI). Spatial distributions of ecological risks based on the PTEs concentration have been explored with Empirical Bayesian Kriging method. The result indicated the mean concentration of PTEs (Cr, Pb, Cu, As and Zn) were significantly higher in dry season than wet season. Based on the PERI and PLI values, the PTEs accumulation are more severe near industrial activities and traffic roads. Hotspots of the PTEs were located in the East and Southeast area. The implications of this study could be used to optimize the management strategies in controlling the PTEs pollution and become a scientific reference for taking environmental protection policies

Abstract:

The protection of resources and the safety of visitors are two essential elements in the sustainability of any tourism destination. The Sangkulirang-Mangkalihat karst has the potential to be developed as a UNESCO Global Geopark based on the diversity and unique nature of its geological heritage. Proper management efforts should be carefully planned to ensure sustainability of the geosite. Intact natural conditions can be a potential hazard to visitors and, conversely, the presence of visitors can interfere with the natural preservation of the sensitive karst area. Physical, biological, and human activities that may endanger visitors should be identified and limiting the number of visitors received by each geosite should also be considered. This paper aims to identify the potential tourism hazards of physical, biological, and human activities and to calculate the tourist’s carrying capacity of three geosites (Tewet cave, Nyadeng lake, and Bloyot cave) in the Sangkulirang-Mangkalihat karst. The identification of potential hazards was conducted in each geosite and analyzed and assessed using management options referencing UNEP, NPSA, and APEC, whereas the carrying capacity was assessed with reference to the Cifuentes formulation. Meanwhile, the carrying capacity was assessed at three levels, namely physical carrying capacity (PCC), real carrying capacity (RCC), and effective carrying capacity (ECC). The highest physical and biological hazards were the ravines in the Tewet cave, as well as a moderate level of risk, such as slippery, steep terrain and the presence of crocodiles. Meanwhile, the potential hazards faced by Nyadeng lake and Bloyot cave were classified as low risk. The carrying capacity assessments indicated that Bloyot cave is able to accommodate the largest number of visitors on a daily basis. Therefore, the carrying capacity results of each geosite can serve as a reference for managers to limit the number of visitors to the site in order to ensure the sustainability of Sangkulirang-Mangkalihat geosites.

Abstract:

Abstract Pindul cave located in Gunungkidul Regency, Gunungsewu Karst Area, Indonesia has a unique characteristic which is dominated by surface rivers (allogenic recharge) and groundwater (autogenic recharge). The main purpose of this study is to analyze temporal variation of flood water hydrogeochemistry in Pindul Cave. Water sampling for flood hydrogeochemistry analysis is taken in the wet season for three selected flood events. Parameters of hydrogeochemistry analysis consist of major dissolved element (Ca2+ and HCO3 −); conductivity; total dissolved solid; SI calcite; log PCO2; and pH. The result shows that there was correlation between flood discharge and hydrogeochemistry parameters. The hydrogeochemistry of flood events in Pindul Cave typified by a low value of calcium and bicarbonate and high CO2 gas content in water that indicated the dillution by precipitation processes. Pindul Cave also show the negative value of calcite during flood event which mean that groundwater is unsaturated, so it becomes aggressive towards calcite. According to the flood water hydrogeochemistry characteristics, Pindul Cave is dominated by conduit flow from the large-fracture that already developed.

Abstract:

The Towakkalak System located in the Maros karst of South Sulawesi is currently the richest of Southeast Asia in obligate subterranean species. It comprises several caves and shafts that give access to the subterranean Towakkalak river as well as many unconnected fossil caves, stream sinks, and springs located within its footprint. The total length of the caves linked to the active system is 24,319 m and comprises two of the longest caves of Indonesia, Gua Salukkan Kallang and Gua Tanette. Studies of its fauna began in 1985. There are 10 stygobionts and 26 troglobionts that are known from the system. The smaller adjacent system of Saripa has 6 stygobionts and 18 troglobionts, of which 1 and 3, respectively, are absent from Towakkalak. Like all tropical cave inventories, our dataset has limits due to identification uncertainties, gaps in habitat (waters, guano) and taxonomic coverage (micro-crustaceans, mites), sampling methods (pitfall trapping, Karaman–Chappuis), and problems of ecological assignment. A number of additional species are therefore expected to be found in the future. The Towakkalak and Saripa cave systems are included in the Bantimurung-Bulusaraung National Park and are under efficient protection, but parts of the Maros karst outside the park are under serious threat, mainly from quarrying.

The karst area in Panggang Subsystem, Gunungsewu has specific hydrogeological properties, including predominant epikarst springs with minimal discharge in dry seasons. Since this situation inevitably leads to drought, the installation of deep wells to extract water from deep aquifers is proposed as an alternative solution to water provision. This study determined the location of these wells using general geological and geomorphological surveys, followed by analyzing the results of geophysical measurements. The results showed potential aquifers in the sand layer of tertiary volcanic aquifers under the limestone formation that makes the karst region. Although three borewells were constructed at three different points, only two of them succeeded and are ready for use to meet the clean water needs of the population at the research site.

Abstract:

Abstract The karst landform holds considerable water resource potential and is known for its underground rivers. On the other hand, the high porosity carbonate rocks on this landform cause the decrease of the natural protection function against groundwater pollution. Hence, the analysis of groundwater vulnerability in the karst area is prominent before making the spatial planning regulation. This recent study aimed to analyze the groundwater vulnerability in the karst area located in a part of Umbulrejo Village, Yogyakarta, Indonesia, and proposed action in groundwater protection. The method used in this research was based on the COP method. The data acquisition was conducted by survey method both for primary and secondary data. The COP (Concentration of flow, overlaying layers, and precipitation) analysis was supported by ArcGis software. The analysis of groundwater vulnerability showed that there were two vulnerability classes, i.e., very high (48.6%) and high (51.4%). These results were influenced mainly by the close distance of the recharge area to swallow holes and the lithology type (karst), which contributed to a very high value in reducing protection against groundwater. A proposed action to support groundwater protection is regulating the land utilization in the area of the settlements.

Abstract:

Irrigation, a critical element in farming, can fulfill crop water needs and increase agricultural productivity during the dry season, provided that the two necessary factors are met, namely water supply and water quality. Water quality is a principal factor in assessing whether or not a water body is usable as a source of irrigation. Excess or lack of elements in irrigation water may affect irrigated crops and soil. For maximum harvests, studies scrutinizing the suitability of water supply for irrigation become necessary. Beton Spring has a large discharge, which the people of Ponjong District, Gunungkidul Regency, rely on for their irrigation and fish farming practices. Uniquely, this karst spring receives allogenic recharges from outside the karst area. This research was intended to assess the suitability of water quality of Beton Spring for temporal irrigation purposes by Sodium analysis (Na%), Sodium Adsorption Ratio (SAR), USSL, and Wilcox. The elements observed in the analysis were Ca2+, Na+, Mg2+, K+ and electrical conductivity. Based on the overall analysis results of the water quality series—Sodium analysis (the water samples were classified as Excellent), SAR (Excellent), USSL (moderate to good), and Wilcox (Excellent to Good), Beton Spring produces good-quality water that is suitable for irrigation.

Abstract:

Marine lake in a karst landscape is one of the macro karst forms known as doline and is only found in some locations in the world. Moreover, the theory of marine doline formation is always associated with global sea-level rise which differs from one place to another due to several factors. This research was conducted to understand the formation process of marine lakes in Misool and how the water fills the basins formed especially at Holocene time. This was achieved by obtaining information on the longest underwater terrace which is also the longest standing water position recorded on the sea wall. The marine terraces were measured by sounding profiles to the sea bordering the seven marine lakes including Lenmakana, Balbullol, Lenkafal, Keramat, Karawapop, Keramat-2, and Keramat-3 as well as Harapan Jaya Sea. A total of 24 profiles were measured and stable isotopes δ18O and δD of water samples were used to determine the origin of water in the lakes. The results showed the longest terrace was at the depth of ˗33 and ˗3 m while the references from the area closest to Misool showed the same water level positions at 10,500 BP and 6,985 BP. Furthermore, the composition of δ18O and δD from lake water indicated the water samples were a mixture of groundwater and seawater with the seawater having the more dominant concentration and this allows it to fill the lake first through a previously formed cavity system.
