Judul: Pengelolaan dan Nilai Ekonomi Rusa (Cervidae) sebagai Objek Wisata di Penangkaran Rusa Lembah Paniisan Subang
Abstrak: Penangkaran Rusa Lembah Paniisan melakukan upaya pengembangbiakan, pelestarian, dan pemanfaatan berkelanjutan terhadap rusa totol (Axis axis) dan rusa timor (Cervus timorensis), termasuk sebagai objek wisata. Penelitian ini bertujuan mengidentifikasi pengelolaan rusa sebagai objek wisata, menganalisis persepsi pengunjung terhadap pemeliharaan rusa dan preferensi untuk berwisata, serta menghitung nilai ekonomi penangkaran. Metode yang digunakan yaitu survey, observasi lapang, wawancara, dan studi pustaka. Hasil menunjukkan pengelolaan rusa (pakan, kandang, kesehatan, dan reproduksi) tergolong baik serta memiliki tingkat keberhasilan penangkaran dengan kategori tinggi, namun masih diperlukan peningkatan pada beberapa indikator. Pengunjung berpersepsi baik terhadap pemeliharaan rusa dan memiliki preferensi tinggi terhadap kegiatan wisata yang melibatkan interaksi dengan rusa. Nilai ekonomi wisata penangkaran berdasarkan kesediaan membayar pengunjung untuk mendukung pemeliharaan rusa sebesar Rp. 13.262.500 dan untuk mendukung pengembangan wisata sebesar Rp. 8.805.000. Wisata dapat dikembangkan melalui pengembangan teknis pengelolaan rusa dan pembuatan paket wisata berdasarkan segmentasi pasar., Paniisan Valley Deer Breeding focuses on the breeding, preservation, and sustainable utilization of spotted deer (Axis axis) and Timor deer (Cervus timorensis), including using the deers as tourist attraction. This study aims to identify the management of deer as a tourist attraction, analyze visitors' perceptions of deer maintenance and their preferences for tourism, and calculate the economic value of the breeding program. The methods used include surveys, field observations, interviews, and literature studies. The results indicated that deer management (feed, enclosures, health, and reproduction) was good and has a high breeding success rate, though improvements were needed in several indicators. Visitors had positive perception of deer maintenance and high preference for tourism activities involving interaction with deer. The economic value of breeding tourism based on visitors' willingness to pay to support deer maintenance was Rp. 13,262,500 and to support tourism development was Rp. 8,805,000. Tourism could be developed by improving the technical aspects of deer management and creating tour packages through market segmentation.

Judul: Welfare Management and Economic Benefit Value of Deer in Lembah Paniisan Deer Captivity Subang
Abstrak: Rusa timor (Cervus timorensis) dan rusa totol (Axis axis) termasuk spesies rusa yang dikembangbiakkan di Indonesia. Jumlah populasi rusa di alam semakin terancam akibat perusakan habitat dan perburuan liar sehingga perlu adanya upaya konservasi ex-situ, salah satunya yaitu Penangkaran Rusa Lembah Paniisan. Penelitian ini bertujuan mendeskripsikan pengelolaan kesejahteraan dan menilai tingkat kesejahteraan rusa, menganalisis tingkat keberhasilan penangkaran, serta menghitung nilai manfaat ekonomi rusa dan dampak sosial ekonominya bagi masyarakat. Metode yang digunakan yaitu observasi lapang, wawancara, dan studi pustaka. Hasil penelitian menunjukkan bahwa pengelolaan kesejahteraan rusa tergolong sangat baik dengan capaian implementasi sebesar 85,10. Tingkat keberhasilan penangkaran tergolong ke dalam kategori tinggi. Nilai manfaat ekonomi rusa dihitung berdasarkan biaya pemeliharaan sebesar Rp5.650.196,08/ekor/tahun, berdasarkan harga pasar sebesar Rp28.800.000– Rp67.500.000/pasang. Nilai keuntungan usaha penangkaran untuk penjualan individu rusa tahun 2022 sebesar Rp45.903.529,41 dan tahun 2023 sebesar Rp61.204.705,88, serta keuntungan penjualan produk turunan rusa sebesar Rp50.900.000/tahun. Nilai manfaat ekonomi penangkaran bagi masyarakat yang terlibat sebagai pekerja dihitung berdasarkan nilai share and covering. Nilai share terhadap total pendapatan rumah tangga sebagai perawat satwa tergolong rendah (47,08%) dan sangat rendah (20,03%) bagi tenaga kerja. Covering pendapatan penangkaran perawat satwa (66,10%) dan tenaga kerja (24,93%) tidak dapat menutupi total pengeluaran rumah tangga., The timor deer (Cervus timorensis) and the spotted deer (Axis axis) are species of deer bred in Indonesia. The number of deer populations in the wild is increasingly threatened by habitat destruction and wild hunting that requires ex-situ conservation effort, one of which is Lembah Paniisan Deer Captivity. The study aims to describe the welfare management and assess the level of welfare of deer, analyze the success rate of captivity, and calculate the value of the economic benefits of the deer and its socio-economic impact on community. The methods used are literature study, field observation, and interview. The results show that animal welfare management was rated as very good with an implementation reach of 85,10. The success rate of captivity belongs to the high category. The economic benefit value of the deer is calculated based on maintenance costs of Rp5,650,196.08/acre/year, based on the market price of Rp28,800,000–Rp67,500,000/pair. Profit value for individual deer sales of Rp45,903,529.41 in 2023 and Rp61,204,705.88 in 2022 and sales of deer-derived products of Rp50,900,00/year. The economic benefits of incarceration for the community involved as a worker are calculated based on share and covering. The share of total household income as a animal keeper is low (47.08%) and very low (20.03%) for the labor force. Covering the captivity income of animal keeper (66.10%) and labor (24.93%) could not cover the total household expenditure.

Judul: Membran Komposit Kitosan-Zeolit untuk Aplikasi Direct Methanol Fuel Cell
Abstrak: Direct methanol fuel cell (DMFC) is a fuel cell that utilize methanol as the fuel source. The electrolyte membrane used in the DMFC system in this research was chitosan-zeolite composite membrane. The composite membrane was synthesized with chitosan-zeolite composition variation of 1:1, 1:2, 1:3, and 2:1. The membranes were analyzed by Fourier transform infrared spectrophotometer (FTIR) and scanning electron microscope, and for the specific gravity. Membrane performances were tested with methanol uptake, methanol permeability, conductivity, and potential difference in the DMFC system. The FTIR spectrum showed no formation of new functional groups inducating that the composite membrane was a result of physical mixing. Morphological analysis showed that the membrane was nonporous. Chitosan-zeolite 1:3 composite membrane had the highest specific gravity and methanol uptake, 1.4226 g/mL and 41.44%, respectively. The highest proton conductivity was showed by the 1:2 chitosanzeolite composite membrane, namely 7.2946× 10-7 S/cm. Based on this research results, chitosan-zeolite composite membrane can be applied in DMFC system.
