Abstract

Biodiversity conservation in national parks has not shown an expected result. Biological natural resources degradation is still on going and its almost entirely due to human activities. Some researchers have indicated that socio-economic aspect is significantly related with the success of conservation. However, the researches have not yet shown in detail, which variabels were related with the succes conservation variables and how significant were the relations. This research was intended to identify the socio-economic variable(s) that would successfully determine biodiversity conservation in national park. The research was conducted in Gunung Halimun Salak Nasional Park, Ujung Kulon National Park, and Gunung Ciremai National Park from July to October 2015 using direct observation, literature study, and interview methods involving 150 respondents, selected based on random sampling in several resorts in the three national parks. Data were analyzed using pearson correlation tests using SPSS PSAW statistic 18. The achievement of biodiversity conservation was determined by the decrease in the number of individual species, increase in the rate of encroachment, increase of illegal natural resource utilization, increase violation of regulation, positive interaction, and biodiversity utilization. Results showed that variables leading to the succesful biodiversity conservation were: 1) determinant variable to decrease in the number of species is religion & customary system; 2) determinant variables to increase in encroachment rate is age and distance; 3) determinant variable to increase illegal natural resource utilization is land ownership; 4) determinant variable to increase violation of regulation is family dependant; 5) determinant variables to positive interaction is age and distance; 6) determinant variable to biodiversity utilization is education.Keywords: biodiversity conservation, determinant variables, national park, socio-economic variables

Abstract

Indonesia merupakan salah satu negara yang memiliki kekayaan jenis satwa liar tertinggi di dunia. Namun demikian, hingga saat ini pemanfaatan satwa liar di Indonesia, khususnya di kawasan konservasi masih belum optimal. Banyak yang beranggapan bahwa pemanfaatan satwa liar di kawasan konservasi harus dilarang karena akan mengganggu keseimbangan lingkungan. Anggapan ini tidak sepenuhnya benar karena pemanenan yang dilakukan pada saat ukuran populasi satwa mencapai daya dukung habitatnya, justru akan menjadikan individu-individu satwa memiliki bobot dan kesehatan yang lebih baik bila dibandingkan bilamana tidak dilakukan pemanenan. Pemanenan dianggap sebagai hama atau pengganggu bagi masyarakat sekitarnya. Upaya pemanenan ini ditujukan untuk menyeimbangkan ukuran populasi pada konteks rantai makanan ekosistem alaminya.

Abstract

 Javan Hawk Eagle is one of the three keys species of the Gunung Halimun Salak National Park and endemic to the island of Java. Protecting the active Javan Hawk Eagle nesting tree is one of the efforts to increase the success rate of Java Hawk Eagle breeding so that information on the distribution and characteris-tics of Javan Hawk Eagle nesting tree is needed. Field exploration was carried out to determine the existence of the Javan Hawk Eagle nest. There were 10 individuals of Javan Hawk Eagle nesting trees which consisted of 5 species namely Rasamala, Huru, Damar, Leng-sar and Manggong with tree architecture models of rauh, massart, scarrone and aubreville, tree height between 26-55 m and height of nests between 18-41m. The Javan Hawk Eagle nesting trees grow in primary, secondary, and plantation forests in a height between 670- 1295 masl, with a steep and very steep slope, the majority of the dis-tance from the river is less than 100 m and the majority of the dis-tance with ecotone is less than 600 m. Javan Hawk Eagle nest on Damar is the first finding at Gunung Halimun Salak National Park.

Abstract

Perluasan perkebunan kelapa sawit yang terus terjadi dianggap memengaruhi keanekaragaman dan kekayaan satwa liar khususnya herpetofauna. Herpetofauna memiliki peran yang penting dalam ekosistem sehingga upaya pelestariannya dalam kajian ekologis perlu menjadi perhatian. Penelitian ini bertujuan untuk mengetahui dampak perkebunan kelapa sawit terhadap keanekaragaman jenis dan komposisi jenis herpetofauna. Pengambilan data dilakukan dengan menggunakan metode Visual Encounter Survey (VES) dengan membandingkan lima tipe tutupan lahan dengan tutupan lahan semak belukar, yang merupakan tipe tutupan lahan sebelum dialihkan menjadi perkebunan sawit. Perubahan dari semak belukar menjadi perkebunan kelapa sawit berdampak positif pada keanekaragaman jenis herpetofauna. Jumlah jenis herpetofauna pada kondisi semak belukar sebanyak 6 jenis dengan indeks kekayaan jenis sebesar 1,48, indeks keanekaragaman jenis sebesar 0,83, dan indeks kemerataan jenis sebesar 0,46. Setelah menjadi perkebunan kelapa sawit, terjadi penambahan 4 jenis herpetofauna, serta peningkatan indeks kekayaan jenis sebanyak 1,09, indeks keanekaragaman jenis sebanyak 1,08, dan  indeks kemerataan jenis sebanyak 0,37. Dengan demikian, jumlah jenis herpetofauna setelah konversi lahan menjadi 10 jenis dengan indeks kekayaan jenis sebesar 2,57, indeks keanekaragaman jenis sebesar 1,91, dan indeks kemerataan jenis sebesar 0,83. Hasil penelitian menunjukkan bahwa perubahan dari semak belukar menjadi perkebunan sawit menyebabkan perubahan pada komposisi jenis herpetofauna sebesar 63%.

Abstract

Peningkatan kerusakan hutan menyebabkan semakin sempitnya habitat orangutan dan diantara upaya konservasi yang dapat dilakukan adalah pengelolaan habitat yang tersisa berdasarkan aspek ekologi orangutan dan kuantitatifnya. Penelitian ini dilakukan di Mentoko, Taman Nasional Kutai, Kalimantan Timur, meliputi penelitian perilaku orangutan dan analisis vegetasi habitat orangutan. Penelitian bertujuan untuk mengetahui pola penggunaan spasial dan pola penggunaan waktu serta ritme orangutan dalam habitat alami. Hasil penelitian menunjukkan bahwa presentase aktivitas harian orangutan di Mentoko lebih banyak berada pada ketinggian 20-30 meter dari tanah dan rata-rata 44,4% dari seluruh kegiatan mereka dihabiskan untuk aktivitas makan, 39,2% untuk istirahat, 11% aktivitas bergerak, dan 5,4% untuk aktivitas lainnya. Pada kondisi yang ideal tanpa gangguan, penggunaan habitat terkait ketinggian orangutan dalam beraktivitas cenderung bervariasi dari posisi rendah sampai tinggi sesuai posisi sumber pakan. Sebaliknya apabila kondisi tidak aman maka akan beraktivitas pada tempat yang lebih tinggi. Pilihan ketinggian posisi untuk membuat sarang, selama pengamatan ketinggian rata-rata dalam membuat sarang lebih dari 20 meter dimana sebenarnya pada kondisi tanpa pengamatan, orangutan seringkali membuat sarang pada ketinggian 8-10 meter dari permukaan tanah dalam penggunaan ruang, orangutan melakukan regenerasi antara 0,65-1,11 km adalah habitat yang terdiri dari 51 jenis pohon dengan indeks keanekaragaman jenis 3,75 yang terdiri atas 25 famili, 36 spesies pada tingkat pertumbuhan tiang dari 19 famili dan 39 spesies pada tingkat pertumbuhan anakan dari 22 famili.

Abstract

Memahami umur satwa merupakan aspek penting untuk mengidentifikasi struktur umurnya. Struktur umur adalah salah satu parameter demografik yang penting untuk dipelajari terkait tujuan pengelolaan populasi. Salah satu teknik estimasi usia dapat didekati dari ukuran organ (morphometric). Penelitian ini dilakukan dari Mei hingga Agustus 2007 pada Pusat Penyelamatan Satwa Cikananga, Jawa Barat dan Kalaweit Pusat, Sumatera Barat. Penelitian ini menggunakan 14 parameter dan 40 sampel dari siamang (Symphalagus syndactylus Raffles, 1821), terdiri dari 24 jantan dan 16 betina. Hasil analisis statistik (regresi linier berganda dengan metode bertahap) korelasi antara umur (Y) dengan lingkar wajah (LM) diperoleh persamaan regresi untuk Umur = -14,546 + 0,801 LM untuk jantan (1-15 tahun), panjang tangan (PTT) dengan Umur = -2,091 + 0,496 PTT untuk jantan (1-6 tahun), lingkar dada (LD) dengan Umur = -15,328 + 0,533 LD untuk betina (2-14 tahun), lingkar dada dengan Umur = -5,331 + 0,312 LD untuk jantan dan betina (1-15 tahun). Ukuran morfologikal dalam hal ini lingkar wajah, panjang tangan, lingkar dada merupakan pertumbuhan panjang hewan yang mudah dilihat dengan mata dan merupakan parameter penentuan kelas umur pada siamang sumatera (Symphalagus syndactylus Raffles, 1821). Parameter morfometrik yangdigunakan merupakan bagian-bagian tubuh yang mudah terlihat dan mudah diukur dan merupakan bagian terpenting dalam sebuah teknik penentuan umur menggunakan metode morfometrik.
