“…Figure 5 demonstrates that the species richness index (Dmg) of mammals is moderate in the lowland forest but low in coastal and mangrove ecosystems. The Margalef species richness index (Dmg) can be categorized as low, moderate, and high, if the values are < 3.5, > 3.5 -< 5, and > 5, respectively (Arini & Wahyuni, 2016). Moreover, mangrove and coastal forest zones are habitats for a variety of other fauna species, such as birds, reptiles, fish, and invertebrates due to the availability of food sources and several species of vegetation, despite the low species richness of mammals (Rajpar & Zakaria, 2014;Zakaria & Rajpar, 2015).…”

The Protected Forest of RPH (Forest Management Resort) Sumbermanjing Kulon is an area, which is susceptible to land conversion due to human activities, such as road construction and tourism. These conditions might harm the habitat of several animals and disturb their movements, specifically in the mammal group. Therefore, the purpose of this research is to determine the distribution and diversity of mammals as the basis for the proper management of the RPH. This research was conducted on a variety of forest habitats located on plot 97A, which covers an area of 331.5 Ha. Moreover, data were collected by creating line transects in this location and then analyzed by constructing a map of the mammals' distribution using the Shannon-Winer diversity index, evenness, and species richness. According to the results, 23 species of mammals were scattered in three types of habitats. The low category of mammal species diversity index was discovered in the mangrove forest (0.69), while the tropical rainforest (2.48) and coastal forest (2.18 were moderate). Furthermore, the mammal species evenness index in the lowland tropical rainforest, mangrove, and coastal forests indicated relatively even results while the highest mammal species richness index was detected in the lowland tropical rainforest. The mammal diversity results can be used by area managers for sustainable management.

“…Namun jika jumlah rusa melebihi daya dukung, maka harus ada penambahan pakan atau pengurangan jumlah rusa supaya seimbang. Ketersediaan pakan sangat mempengaruhi perkembangan dan status dari satwa liar (Arini & Wahyuni, 2016). Semua jenis satwa liar akan merasa nyaman ditempatnya jika pakan cukup dan bebas dari ancaman.…”

Javan Deer (Rusa timorensis de Blainville, 1822) is listed as the protected animal. Breeding effort should be conducted to conserve the Javan deer and can be developed into a business. The investment cost of deer captive breeding in Tahura Wan Abdul Rachman Lampung is prohibitive, therefore, the research to determine the technical and financial feasibility was conducted. The method used was a cropping system for feed productivity analysis, and Net Present Value (NPV), Break Event Point (BEP), Benefit Cost Ratio (BCR) and Payback Period (PP) for analysis of investment criteria. The study showed that the productivity of feed 135.302 kg/year and daily consumption was 5,5 kg. Analysis with interest rate of 12 % revealed that the BEP value for deer volume was 817 deer, BEP deer price was Rp. 1.634.405.600, admission ticket was 1.634.406, the ticket price was Rp. 377.130/ticket. The volume of car parking services was 2.724.009 cars, BEP car price for parking was Rp. 3.570.130/car, the volume of motorcycle parking services was 4.086.014 BEP motorcycle of parking was Rp. 1.912.928. NPV was minus (3.987.612.310), BC/R 0, PP was 34 years. It concluded that although technically feasible, Javan deer breeding was not feasible financially. ABSTRAK Rusa Jawa Rusatimorensis (de Blainville,1822) termasuk satwa yang dilindungi, kegiatan penangkaran bertujuan menjaga kelestarian jenis dan penangkaran dapat dikembangkan menjadi bisnis. Biaya investasi penangkaran rusa Tahura Wan Abdul Rachman Lampung tergolong tinggi makadilakukan penelitian bertujuan untuk mengetahui kelayakan teknis maupun finansial. Metode penelitian ialah sistem pangkas untuk analisis produktivitas pakan sertametode analisis kriteria investasi dengan pendekatan Net Present Value (NPV), Break Event Point (BEP), Benefit Cost Ratio (BCR) dan Payback Period (PP). Hasil analisis diketahui produktivitas pakan 135.302 kg/tahun, tingkat konsumsi 5,5 kg/ekor/hari. Analisis finansial dengansuku bunga 12% menunjukkan nilai BEP untuk volume rusa 817 ekor, BEP harga rusa Rp. 1.634.405.600, BEP volume karcis masuk 1.634.406 lembar, BEP harga karcis Rp. 377.130, BEP volume jasa parkirmobil 2.724.009, BEP harga Rp. 3.570.130, BEP volume jasa parkir motor 4.086.014, BEP harga Rp. 1.912.928. Nilai NPV minus (3.987.612.310), nilai B/C R 0, PP 34 tahun. Disimpulkan bahwa secara teknis usaha penangkaran rusa jawa layak namun secara ekonomi tidak layak Kata kunci : Manfaat, rusa, konservasi, penangkaran Tanggal diterima: 8 Agustus 2017; Tanggal direvisi: 28 Mei 2018; Tanggal disetujui:

“…Sebagaimana yang dikemukakan oleh (Odum, 1993) bahwa keanekaragaman jenis mempunyai sejumlah komponen yang dapat memberikan reaksi secara berbeda-bedterhadap faktor-faktor geografi, perkembangan atau fisik. Indeks kelimpahan pada semua tingkat pertumbuhan menunjukan nilai dalam kisaran 0,78 -0,95 yang berarti pola penyebaran individu tiap jenis hampir merata (Arini dan Wahyuni, 2016). Selain itu pancang memiliki indeks kelimpahan tertinggi sebesar 0,95 yang nilainya sama dengan indeks kelimpahan pancang di hutan alam pada penelitian Arbainsyah et al, (2014).…”

ABSTRAKHutan sekunder di Indonesia yang mencakup 24,2 % luas daratan Indonesia sebagian besar merupakan bekas pengusahaan hutan. Wacana pengelolaan kawasan hutan ke dalam Kesatuan Pengelolaan Hutan (KPH) sebagai unit pengelolaan hutan terkecil telah ditetapkan, termasuk pada area hutan sekunder bekas pengusahaan hutan. Pemahaman tentang vegetasi hutan sekunder bermanfaat dalam menentukan arah pengelolaannya di masa depan. Penelitian ini bertujuan untuk menganalisis komposisi, keragaman dan struktur pohon hutan sekunder bekas pengusahaan hutan di Nunuka Bolaang Mongondow Utara, Sulawesi Utara. Pengumpulan data berupa jumlah dan nama jenis pohon dilakukan dalam plot ukur 20 m x 20 m sejumlah 30 buah. Penelitian dilaksanakan pada bulan Nopember 2014. Tercatat sebanyak 84 jenis pohon di dalam plot pengukuran. Perhitungan Indeks Nilai Penting (INP) menunjukkan jenis pionir yaitu Anthocephalus macrophyllus mendominasi tingkat pertumbuhan pohon. Sementara itu tingkat tiang dan pancang didominasi oleh satu jenis yaitu Eugenia sp. Indeks Shannon-Wiener menunjukkan keragaman vegetasi termasuk rendah dan sedang. Sementara itu kelimpahan jenis pada tingkat pohon, tiang dan pancang termasuk hampir merata. Kerapatan vegetasi pada seluruh tingkat pertumbuhan sebesar 485,83 individu pohon/ hektar, rata-rata bidang dasar sebesar 35,15 m 2 /hektar. Struktur tegakan berdasarkan grafik kelas diameter tidak menyerupai huruf J terbalik sebagaimana sebaran diameter pohon di hutan alam primer. Namun struktur tegakan berdasarkan INP pada tingkat pohon dan pancang justru menyerupai huruf J terbalik. Kata kunci: komposisi jenis, struktur, hutan sekunder, Bolaang Mongondow Utara ABSTRACT
