Abstract

Tujuan penelitian adalah untuk menganalisis prospek konservasi tumbuhan di areal Nilai Konservasi Tinggi (NKT) perkebunan kelapa sawit dengan berdasarkan nilai kelestarian spesies tumbuhan dan struktur populasi. Penelitian dilakukan di areal NKT tiga perusahaan perkebunan kelapa sawit dan hutan sekunder di Provinsi Riau. Pengumpulan data dilakukan dengan analisis vegetasi berukuran 1,28-2,56 ha/plot di areal NKT dan 3,84 ha/plot di hutan sekunder. Analisis data dilakukan dengan menggunakan kerapatan relatif, dan analisis kondisi regenerasi yang dimasukkan dalam lima kategori (good, poor, fair, none, new). Analisis data terkait penilaian prospek areal NKT dilakukan dari hasil analisis efektivitas areal NKT dan kelestarian tumbuhan. Penilaian prospek areal NKT dikelompokkan menjadi tiga kategori yaitu prospektif, cukup prospektif, dan belum prospektif. Hasil penelitian menunjukkan bahwa areal NKT belum efektif dan kondisi spesies tumbuhan penting yang belum lestari. Areal NKT belum efektif dinilai dari perbandingan nilai komunitas vegetasi antara areal NKT dengan hutan sekunder termasuk rendah (<25%). Areal NKT PT A yang berbentuk hutan memiliki nilai efektivitas lebih tinggi dibandingkan dengan areal NKT lainnya dan hutan sekunder. Hasil penelitian menunjukkan bahwa kondisi regenerasi spesies tumbuhan penting paling banyak termasuk kedalam kategori none (57,14%). Kategori ini menunjukkan spesies tumbuhan belum lestari dikarenakan hanya ditemukan pada satu tingkat pertumbuhan yaitu pohon. Tujuan keberadaan areal NKT adalah menjaga dan melestarikan keanekaragaman tumbuhan yang ada di perkebunan kelapa sawit belum terlaksana dengan baik.

Abstract

Hunting tourism is a form of sustainable use of wildlife that can be done through commercial hunting, thus commercial hunting can contribute to the national economy. Indonesia has 11 public hunting areas but none are well-operated. Beside public hunting area, Indonesia also has private hunting areas. One such place is Desa Pelangi Sentul Private Hunting Area, located in Babakan Madang Sub-Districts of Bogor District, West Java. The objective of this study was to examine the financial benefits of private hunting area in Desa Pelangi Sentul Private Hunting Area through the calculation of Net Present Value (NPV), Benefit Cost Ratio (BCR), and Internal Rate of Return (IRR). The financial analysis showed that Desa Pelangi Sentul Private Hunting Area exertion gained NPV Rp 13 413 719 092 , BCR 1.563, and IRR 18% .This means the exertion is acceptable. Sensitivity analysis also showed that De’Pes Private hunting Area exertion could be held until the benefit decreased 10% with the investation cost fixed, and the investatioin cost increased until 180% with the fixed benefit.

Abstract

Trade of reptiles in regional and international have been increased every year. The trade of reptileswas three divided, that is pet reptile, consumption reptile and reptile skin. The trade of skin reptile was greater than pests, because the skin of reticulated python is the most popular and to be excellent among exporters. Quotas export is all of number of quota exporter should be traded by exporter to international. This study aimed to identify of key variables exporter and formulation of calculation quota exporters of reticulated python. The methods used in this research were examination of administrative documents exporters and direct observation to the enclosure to 44 exporter skin of phyton reticulated. The key variables have corelate with the calculation of quota exporter are export realization ofthe previous year (X1), labor (X2), crusted product (X4), investment value (X5), yield (X6), PNBP (X7), state of export (X8), time of realization (X9), conservation activities (X10), chemicals (X11), and electricity (X12). Based on the analysis of linier regression formula obtained quota determination exporter: Y = 2.001 + 0.002 X3 + 0.072 X4 + 0.080 X5 + 0.030 X6  – 0.384 X9  + 0.059 X10. The result of regression equation of adjusted R square is 0.916. It means that the quation of regression linear is 91.6% for calculation of quotas as it could be explained by finished product, products crusted, yield, investment, time of realization and conservation activities, while 8.4% is explained by variables that are not included in of this research. Variables were positively related to the calculation of export quotas include finished product (X3), product crusted (X4), investments (X5), yield (X6), and conservation activities (X10), while the variables that have a negative relationship is time of realization ( X9).

Abstract

Beberapa penelitian sebelumnya menyebutkan bahwa perubahan tutupan lahan menjadi perkebunan kelapa sawit menyebabkan kehilangan jenis satwaliar, salah satunya dari kelompok mamalia. Oleh karena itu, diperlukan data mengenai bagaimana besarnya kehilangan jenis tersebut. Penelitian ini menduga besaran kehilangan dan perolehan jenis mamalia akibat adanya pembangunan perkebunan kelapa sawit. Data diambil dengan pengamatan langsung (metode strip transect) secara paralel di perkebunan kelapa sawit PT. Rambang Agro Jaya, Sumatera Selatan. Penelitian ini dilakukan pada tutupan lahan antara sebelum (semak belukar) dan setelah adanya perkebunan kelapa sawit. Hasil penelitian ini menunjukkan bahwa perubahan dari semak belukar menjadi perkebunan kelapa sawit tidak mengubah jumlah jenis mamalia, namun meningkatkan indeks kekayaan jenis dan menurunkan indeks kekayaan jenisnya. Indeks kesamaan jenis antara semak belukar dan perkebunan kelapa sawit adalah 0,56. Pembangunan perkebunan kelapa sawit juga menyebabkan kehilangan dan perolehan jenis mamalia dengan persentase yang sama, yaitu 67%. Keberadaan mamalia setelah adanya perkebunan kelapa sawit diduga disebabkan karena ketersediaan pakannya.

Abstract

Tarsius lariang (T. lariang) is an endemic species in Lore Lindu National Park (LLNP). Available information regarding T. lariang is limited to only morphological, anatomical, cytogenetic, and voices issues. Knowledge for its geospatial characteristics such as spatial preferences and spatial distribution is rare. The main objective of this study is to identify the spatial distribution pattern of T. lariang in LLNP. An additional objective is to identify the environmental factors affecting its spatial distribution patterns. Field observation for distribution pattern was done at the observation plot that were using systematic sampling with random start. Furthermore, the density estimation in each point was calculated using Triangle Count and Concentration Count method, while insect abundance was estimated using light traps sample data. Finally, spatial pattern was estimated using nearest neighbor index, while the environmental affecting factors were identified by using spatial analysis and correlation analyses. From 45 observation points, the T. lariang distribution pattern was clumped. It is also recognized that the significant factors affecting the spatial distribution were insect abundance, proximity from the commercially utilized land, and land surface temperature.

Abstract

Illegal wildlife trade is a criminal act of enormous value, almost equivalent to drug trafficking. One species vulnerable to being traded illegally is the moluccan eclectus which has a high number of enthusiasts. Law enforcement in cases of illegal wildlife trade in Indonesia is difficult because there is no standardization in calculating the economic value of wild animals. The economic valuation approach is one approach in quantifying the economic value of wildlife. This study aims to analyze the economic value of moluccan eclectus based on the market price approach, analyze the economic value of moluccan eclectus based on the maintenance cost approach, and compare the two approaches in the economic valuation of moluccan eclectus. Data were collected by two methods, namely literature study and interviews. The literature study collects data in the form of moluccan eclectus market prices circulating in the domestic and international markets. Meanwhile, interviews were conducted with managers of conservation institutions at Siantar Zoo, Medan Zoo, Tasikoki Animal Rescue Center (PPS) Manado, Taman Mini Indonesia Indah Bird Park in Jakarta, Kekewang Zoo in North Sulawesi, and Andy Hoo Captivity in East Java to obtain data on maintenance cost. Data analysis was carried out quantitatively and qualitatively. The results showed that the economic value of moluccan eclectus based on the market price approach reached IDR 16,138,820/individual. Meanwhile, based on the maintenance cost approach, the economic value of moluccan eclectus reaches IDR 6,313,333/individual. Based on the accuracy of the results, both approaches have the same level of accuracy. Meanwhile, based on the effectiveness and cost-efficient aspects of data collection and analysis, the market price approach is relatively better than the maintenance cost approach. Key words: Economic valuation, illegal wildlife trade, moluccan eclectus

Abstract

The movement of Sumatran elephants from forests to villages and agricultural lands triggers elephant-human conflicts. The increase in conflict between Sumatran elephants and humans has caused a drastic decline in the Sumatran elephant population. The decline in the Sumatran elephant population indicates the importance of the conservation efforts carried out on the results of research studies related to the traces of Sumatran elephant activities. This study aims to analyze the relationship between activity traces and the characteristics of the Sumatran elephant habitat at Pemerihan Resort. The research was carried out from July 2021 to January 2022. The direct observation carried out in the observation line is 1 km long and 250 m wide (4 transect lines) with 4 repetitions. The results showed that the spatial distribution of Sumatran elephant activity traces is related to habitat characteristics, namely land cover type (secondary forest), topographic class (flat), distance from water sources (<1000 m), and distance from settlements (1000-2000 m). Traces of activity can be interpreted as an indicator of knowing the presence of Sumatran elephants that can prevent and minimize conflict levels. Management of the habitat and population of Sumatran elephants through enrichment of feed and captive activities is needed as a form of Sumatran elephant conservation efforts. Keywords: activity traces, habitat, Pemerihan Resort, Sumatran elephant

Abstract

Sun bear (Helarctos malayanus) and sumatran elephant (Elephas maximus sumatranus) are two species with high population decline due to poaching and illegal wildlife trade. It is still difficult to enforce laws related to hunting and wildlife trade due to legal standardization that can be used as an economic basis for lawsuits. One method of quantifying the economic value of animals can be done through an economic valuation process. This study aims to examine the economic value of sun bears and sumatran elephants based on a maintenance cost approach. The research was conducted at the conservation institutions of Medan Zoo, Siantar Zoo, and PPS Tashikoki from February – May 2021. The method used in the study was to manage conservation institutions to obtain the amount of cost allocation for animal care that refers to the five principles of animal welfare. The results showed that the sun bear's economic value based on its maintenance cost for 2 years reached Rp. 76,760,000 and for the sumatran elephant, it reached Rp. 621,730,000. The highest maintenance cost allocation for these two species is in the feed allocation. This high economic value indicates a disproportionate amount of fines given to the perpetrators of hunting and illegal wildlife trade, which has implications for weak legal products and does not cause a deterrent effect.
