Abstract

Banteng (Bos javanicus d’Alton)  dikonservasi  serta didomestikasi sebagai sapi bali (Bos taurus Linnaeus) sejak 3.500 SM. Tujuan penelitian ini adalah memperoleh informasi hasil analisis morfometrik banteng dankeragaman genetik populasi banteng di dalam kawasan konservasi dan lembaga konservasi serta hubungan kekerabatan antara populasi banteng dengan sapi bali melalui jarak genetik antar populasi dan jarak genetikantar individu dengan metode multiple alignment sekuen dari program Clustal X 1.83 serta analisis filogenetik menggunakan metode neighbor-joining. Morfometrik banteng di Kebun Binatang Surabaya dan Kebun Binatang Ragunan telah mengalami perubahan secara fisik dan biologis, hal ini terjadi karena jarak genetik di dalam populasi sebesar 0,000. Di kawasan konservasi, morfometrik banteng paling besar dari Taman Nasional Baluran dilihat dari ukuran telapak kaki dan jarak kaki.  Hasil multiple alignment 657 urutan basa fragmen D-loop DNA mitokondria, terdiri dari enam haplotipe yaitu banteng 3 macam haplotipe dansapi bali 5 macam haplotipe, dengan demikian sapi bali memiliki keragaman genetik lebih tinggi. Jarak genetik antar haplotipe sangat kecil (0,000-0,009), sehingga hubungan kekerabatan antara banteng dan sapibali sangat dekat. Dengan demikian untuk program pemuliaan, sapi bali dapat dilakukan perkawinan silang dengan banteng dari taman nasional.

Abstract

Kajian keragaman genetik dari populasi trenggiling (Manis javanica Desmarest, 1822) belum banyak dilakukan. Penelitian ini menganalisis sekuen fragmen D-loop DNA mitokondria trenggiling, yang bertujuanuntuk menyelidiki diversitas genetika trenggiling dari dua populasi, yaitu kawasan konservasi dan lembaga konservasi di Sumatera Utara dan Jawa. Fragmen D-loop DNA mitokondria yang teramplifikasi sepanjang 1129 pasang basa, terdapat 55 haplotipe dengan 120 situs, dan 12 haplogroup.  Tiga frekuensi haplotipe tertinggi dijumpai pada H-19 (9,09%), H-15 dan H-43 (3,64%), dan lainnya 1,8%. Jarak genetik antarhaplotipe trenggiling berkisar antara 0,001-0,099 dengan rata-rata 0,012. Jarak genetik haplogroup dengan reference berkisar 0.001-0,019; jarak genetik dalam haplogroup berkisar antara 0,003-0,015; jarak genetikantar haplogroup berkisar 0,003-0,021, dan jarak genetik antara haplogroup dengan outgroup berkisar 0,0940,109. Diversitas nukleotida (Pi) sebesar 0,008 dan diversitas haplotipe (Hd) 0,994±0,006, yangmenunjukkan keragaman genetik yang tinggi. Hasil Tajima test pada jarak genetik antar haplotipe populasi trenggiling menunjukkan nilai D: -2,337 (berbeda nyata pada taraf P<0,1), sedangkan hasil Fu and Lis testmenghasilkan D: -4,444 dan F: -4,337 (berbeda nyata pada taraf P<0,02). Hal ini merupakan indikator tingginya keragaman genetik dan ekspansi populasi trenggiling.

Abstract

Forest land converted into palm oil plantations have caused habitat fragmentation of elephant and land degradation. These lead to land use conflict between human and elephant. The conflict often caused the elephant killed and destructed agricultural land. The study was aimed to estimate potential use and carrying capacity of elephant habitat. Data collection of undergrowth vegetation were analyzed using twelve square plots of 1 x 1m, the distance between the plot of 50 m, tree vegetation of seedlings size 1 x 1 m, saplings 5 x 5 m, and trees 20 x 20 m, the distance between the plot of 200 m and of 1000 m lenght. Vegetation used as elephants feed were observed using purposive sampling and systematically procedure. The analysis showed that biomass of plants producing elephant fodder in Tambang Besi were of Cyperus rotundus (3600.26 kg/ha), Cynodon dactylon (346.74 kg/ha), Melaleuca leucadendron (255.21 kg/ha), and Melastoma malabatricum (156.40 kg/ha). While, the highest biomass in Tebing Penigasan plot is Cyperus rotundus (3575 kg/ha), and in Barak Gajah Plot is Isachne globusa (4013.33 kg/ha). The carrying capacity of elephants habitat of Tambang Besi, Tebing Penigasan, and Barak Gajah plots are 0.78, 0.29, and 0.41 individual/ha/day, respectively.

Abstract

The use of alternative feed for Sunda pangolin in captivity is one way to cope with a shortage of feed. The aims of the research was to determine the impact of the use of alternative feed toward feed consumption and daily weight gain of pangolin in captivity. The research was conducted at Research Forest Dramaga, Bogor. The research material used by 4 individual pangolin consists of 2 males and 2 females with an average weight of 4.28 ± 0.22 kg. Research using 4x4 Latin Square Design, with 7 days of preliminary period and 14 days of data collection. The treatment applied were 4 alternative feeding i.e A= 50% kroto + 50% egg; B= 50% kroto + 50% tofu; C= 50% kroto + 20% egg + 30% tofu; D= 50% kroto + 18% egg + 26% tofu + 6% termites. The results showed that the effect of alternative feed not significantly (P<0.05) on feed consumption and body weight gain pangolin. Pangolin with treatment C consumed feed based on dry matter as much as 63.08 grams per day or 10.46% from body weight and the biggest weight gain 35.0 grams per individual per day.

Abstract

Illegal wild animal trade is a conservation threat, predominantly in Indonesia. Most of the animals traded is the pangolin which almost all parts of the body are used, especially the scales. This research used a bibliometric review that uses Scopus, The Web of Science platform, and Google Scholar to analyze publications for one decade to map trends and gaps in pangolin research. The result of this research showed that the total of publications significantly increased over several decades, but the topic for pangolin research is not learned in the same proportion (only 37% of them discussed the population appraisal of pangolin in the wild, the remainder mostly discussed status and conservation of pangolin in 41%, and the effect of illegal pouching and trading in 22%). There is an inconsistency between the researchers in developed countries and developing countries where more research is conducted in developed countries than in developing countries. The data from the analysis research collected systematically in developing countries were not published proficiently, therefore it caused several publications to fall into the grey literature category. There are some research gaps, which are research topics are not diverse and have too many things in common, other than that the population data are not aligned with the biodiversity distribution and conservation priorities, especially concerning endangered species such as pangolins. The success of conservation relied on the policymakers and practitioners, and the implications of this research gave suggestions for the management to overcome the pangolin trade polemic that has become increasingly widespread recently.

Abstract

The analysis of public information disclosure policy implementation is a crucial step in improving services and providing strategic references for government public information programs. The Forest Management Technical Personnel Information System (SIGANISHUT) was developed under the Ministry of Environment and Forestry (MoEF) Regulation No. 8 of 2021. This study examined the implementation of public information disclosure within SIGANISHUT, which is managed by the Directorate of Fees and Forest Product Distribution, Directorate General of Sustainable Forest Management. Using qualitative methods—including in-depth interviews, literature reviews, and observations—this study found that SIGANISHUT is managed with a user-centered approach. However, challenges persist regarding resource availability and disposition. The system requires additional personnel and increased budget allocation to support field-level policy socialization. Despite these challenges, policy implementers demonstrate accountability in implementing MoEF Regulation No. 8 of 2021 and respond effectively to user complaints and operational issues. From a bureaucratic perspective, the current framework adheres to the Standard Operating Procedures outlined in the regulation, with a well-coordinated division of responsibilities among implementers. SIGANISHUT streamlines bureaucracy by reducing service times through digital integration.With sufficient support and well-designed policies, the legislative mandate on public information disclosure can be implemented more effectively and efficiently. This study underscores the importance of continuous evaluation and development to ensure SIGANISHUT meets stakeholder expectations and contributes to transparency and accountability in sustainable forest management.

Abstract

Currently, ecotourism has become an important industry because of its rapid development. Many tourism practices have adverse environmental impacts. Due to the increasingly destructive commercialization of the natural resources on which we depend, there are several negative impacts. Aek Nauli Research Forest (ANRF), with an area of 1,900 hectares, is one of the natural tourist destinations around the Lake Toba Tourism area managed by the Aek Nauli Research Institute for Environmental and Forestry Development (BP2LHK). The location of the study is in Girsang District, Sipangan Bolon, Simalungun Regency, North Sumatera Province. The tourist objects are natural panorama, elephant conservation education tour, and siamang animal ape park. On average, the number of visitors of ANRF on regular days is 100-300 visitors/day and on holidays reaches 300-1,700 visitors/day. The increase in the number of visitors is perceived to have an impact on environmental sustainability. This study aims to determine the capacity of the ANRF ecotourism area to accommodate the number of tourists per day simultaneously. The method used is the effective carrying capacity by Cifuentes method based on several stages of analysis, namely Physical Capacity (PCC), Real Capacity (RCC), Management Capacity (MC), and Effective Capacity (ECC). The environmental carrying capacity analysis results showed that the PCC, RCC, ECC were 26,106 visitors/day, 3,007 visitors/day, 2,505 visitors/day respectively while MC was 0.83. This value can be used to advise managers to limit visitors, particularly during peak season, in order to preserve objects and the quality of visits.
