Judul: Welfare Management and Health Status of Deer at Captivity Hutan Penelitian Dramaga, Bogor
Abstrak: Keberadaan rusa timor (Rusa timorensis), rusa sambar (Cervus unicolor), dan rusa bawean (Axis kuhlii) di alam perlu dipertahankan. Salah satu lembaga yang mendukung kegiatan konservasi eksitu tersebut adalah Penangkaran Rusa Hutan Penelitian Dramaga, Bogor. Penelitian ini dilakukan dengan menilai penerapan manajemen kesejahteraan satwa dan status kesehatan satwa. Data kesejahteraan rusa diperoleh melalui observasi lapang, wawancara dan pengisian kuisioner. Status kesehatan rusa berdasarkan kejadian infeksi cacing saluran pencernaan (helminthosis) diperoleh dengan melakukan pengambilan sampel feses, kemudian dianalisis secara mikroskopis melalui metode McMaster, flotasi sederhana dan saringan bertingat modifikasi. Hasil penelitian menunjukkan bahwa pengelolaan kesejahteraan rusa di penangkaran rusa Hutan Penelitian Dramaga tergolong “baik” dengan skor tingkat kesejahteraan satwa mencapai 73,03. Telur cacing parasit yang ditemukan yaitu Trichuris, Strongyloides dan Trematoda yang menginfeksi rusa, dengan derajat infeksi TTGT tergolong dalam kategori rendah., The existence of timor deer (Rusa timorensis), sambar deer (Cervus unicolor), and bawean deer (Axis kuhlii) in the wild needs to be preserve. One of the responsible institutions in ex-site conservation activities is deer captivity of Dramaga Research Forest, Bogor. The study was conducted to assess the implementation of animal welfare and animal health status. Data of deer walfare management was obtained by field observations, interview, and filling the questionnaire. Deer health status based on the gastrointestinal endoparasites infection (helminthosis) was obtained by collected faecal sample, then it was analyze with microscopic evaluation by McMaster, simple flotation and modification of sedimentation technique. The study shows that deer welfare management in deer captivity of Dramaga Research Forest was classified as a “good” with a score of animal walefare’s level up to 73,03. All animals were parasitized by Trichuris, Strongyloides, and Trematode with low infection intencity level EPG.

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: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
