<p>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. </p><p><strong>Keyword</strong>: predator, tropical, karst, Gunungsewu</p><p> </p>

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.

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.

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

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.

Studies on karst is a study that can be done hotisticaliy, because in the karst region them are various potentials such as; prehistoric archaeological remains which are quite old, there am groups of people who have local knowledge seekers swallow nest, traditional agricultural activities and the utilization of the site of the settlement (settlement area), as well as habits embodied in traditions and art. Through archaeological approach to spatial {spatial archeology), the archaeological research in East Kutai Karst, not only reveal the spatial and temporal aspects alone, but as a whole want to explain culturally and physically; synchronic and diachronic this region inhabited by humans. Mangkulirang karst area is so vast traffic would require a study to obtain an explanation; subsistence, technology and the ancient environment, as well as the adaptation of the system that have become extinct Cave sites and niches in the Mangkulirang a valuable contribution to the knowledge of the history and prehistory of cultural processes. Any kind of potential above require management in the context of synergy, participation and shared responsibility with the local authorities, cross-institutional and community organizations, as well as cross-sectoral and multi-disciplinary to minimize conflicts of the various interests in the karst region in the management and preservation of cultural heritage Indonesia. AbstrakKajian tentang karat adalah kajian yang dapat dilakukan secara holistik, karena di daiam kawasan karst tendapat berbagai potensi seperti; tinggalan arkeologis prasejarah yang cukup tua, terdapat keiompok-kelompok masyarakat yang memiliki kearifan lokal, para pencari sarang waist, aktivitas pertanian tradisional dan pemanfaatan menjadi lokasl pemukiman, serta kebiasaan-kebiasaan yang dlwujudkan daiam bentuk tnadisl dan kesenian. Melalui pendekatan arkeologi kemangan, maka penelitian arkeologi di Karst Kutai Timur, tidak hanya mengungkapkan aspek spasial dan temporal saja, tetapl secara utuh ingin menjelaskan secara kultural maupun fisikal; sinkronik maupun diakronik kawasan ini dihunl manusia. Kawasan karst Mangkulirang yang begitu luas tentunya memerlukan iintas kajian untuk memperoleh penjelasan; subsistensi, teknologi dan lingkungan purba, serta sistem adaptasi yang teiah punah. Situs gua dan cernk di kawasan Mangkulirang dapat memberlkan kontribusl berharga tarhadap pengetahuan sejarah dan proses budaya prasejarahnya. Sagaia jenis potensi di atas memerlukan pengeioiaan daiam rangka sinergitas, peran serta dan tanggung jawab bersama dengan pemerintah daerah, iintas kelembagaan dan organisasi masyarakat, maupun lintas sektoral dan multi disiplin untuk meminimalisir benturan atas berbagai kepentingan di kawasan karst dalam rangka pengelolaan dan pelestarian cagar budaya Indonesia.

Flying over the patchwork quilt of land uses that comprise Southeast Asia, one often sees extensive tracts of rugged topography with plateaux pitted with depressions, deep gorges, rivers arising at the bases of mountains, and towers arising from alluviated plains. These are the karst lands, formed on limestone bedrock and subject to the solutional erosion of that bedrock above and below ground. With a total area of about 400 000 km2, Southeast Asia contains some of the more extensive karst regions in the world. Many of these karst areas are of high relief with spectacular arrays of tower and cone karst. Many have now been inscribed on the World Heritage list in recognition of their unique geomorphology and biology. They are scattered throughout the islands of the Malay archipelago as well as the adjoining fringe of the Asian mainland. Karst is found in Malaysia, the Philippines, Thailand, Brunei, Indonesia, Cambodia, Viet Nam, Lao PDR, and Papua New Guinea. Geologically the carbonate rocks hosting karst range in age from Cambrian to Quaternary, a span of about 500 million years (Letouzey, Sage, and Muller 1988). Over that time limestone solution and other landscape processes have produced an array of karst landforms including towers, cones, plateaux, and dolines, underlain by extensive cave systems. There have also been strong external influences of tectonism, eustatic, and climatic change. Today human modification of karst processes and landforms is proceeding at a rapid pace. Despite their characterization as the ‘botanical hothouse extreme’ (Jennings 1985) the karstlands of Southeast Asia are most diverse, reflecting the influence of varied geology, uplift history, eustatic change, and climates past and present. Karst landscapes range in elevation from sea level to nearly 4000 m, and comprise extensive plateaux with dolines, tower karst, cone karst, and lowlying swampy terrain. The carbonate rocks on which they have formed range widely in age, and can be soft and impure or hard and crystalline. Many areas have been wholly or partially blanketed by volcanic ash during their evolution.

In this abstract, a case study from offshore Indonesia is showcased with examples emphasizing integrated wave field separation methods with the objective of diffraction imaging towards refined karst feature and fault identification. For imaging optimally all diffraction energy, pre-migration and post-migration methods have been integrated. The dataset and examples in this abstract are in a complex geological setting in a very shallow water environment, with a subsurface that is characterized by large carbonate pinnacles containing large amount of karst features with thinning and thickening carbonate layers. For the purpose of refined imaging of diffraction energy only, the total wave field has been separated into specular reflections and diffractions prior to migration and these have been integrated with existing post-migration wave field separation methods. Both the pre-migration and post-migration wave field separation methods have their advantages and disadvantages and is discussed later in this abstract. Diffraction energy, in general is much lower in amplitude than the specular reflections and separately imaging these, unveils higher resolution small scale geological features such as karst features and faults complementing the total wave field PSDM data. With existing industry available methods applying wave field separation in either pre-migration or post-migration stage, limitations have been observed, and therefore we propose in this abstract to integrate both methods and take advantage of the improvements showcased with examples throughout the abstract.

The formation has multiple lost circulation zones below the 9 5/8" casing shoe that is prone to total and partial losses due to combination depleted formation in the upper side and the nature of karst or fractured carbonate formation in middle and lower part of the interval. In addition, the bottom part of the hole section has problematic wellbore instability. These hazards lead to the necessity to closely monitor and control the pressure profile throughout the operation to find balance between loss circulation and wellbore stability to ensure an efficient and safe operation. An automated MPD system is used to precisely control bottom hole pressure. MPD system was used to drill 8-1/2" section of ZX well smoothly to target depth and geological objective was achieved without NPT. MPC was performed successfully for 7" liner cementing. This was the first MPC operation in offshore Madura and the application mitigated the loss circulation and avoided the unnecessary remedial cementing job. The paper will share the success story of MPD application in drilling narrow window ERD well in offshore Madura, Indonesia. It aims to describe the application of MPD for this specific ERD case from planning phase to execution phase as well as the lesson learned.
