Judul: The principles of animal welfare on the use of Southern pig-tailed macaque (Macaca nemestrina) at Macaca nemestrina Training Place, Pariaman Town
Abstrak: Beruk merupakan jenis monyet yang mempunyai ekor pendek seperti ekor babi, sehingga sering disebut pigtail monkey. Beruk termasuk ke dalam kategori Endangered oleh International Union for Conservation of Nature (IUCN). Salah satu pemanfaatan beruk dilakukan di tempat pelatihan beruk, Kota Pariaman. Beruk dilatih untuk dimanfaatkan menjadi rekan kerja di perkebunan kelapa. Pemanfaatan beruk sebaiknya tetap mengacu pada prinsip kesejahteraan hewan dimana satwa liar harus dipelihara pada lingkungan yang dapat memberikan pilihan bagi satwa untuk dapat berperilaku seperti di habitanya. Studi pustaka ini bertujuan mengetahui prinsip-prinsip kesejahteraan hewan dan dampaknya terhadap pemanfaatan beruk di tempat pelatihan beruk. Data yang dikumpulkan dianalisis dan dibandingkan dengan hasil penelitian lainnya secara naratif deskriptif. Prinsip lima kebebasan menjadi parameter kesejahteraan beruk yaitu bebas dari rasa lapar dan haus, bebas dari rasa tidak nyaman, bebas dari rasa sakit, luka dan penyakit, bebas dari rasa takut dan stress, dan bebas untuk mengekspresikan tingkah laku alamiah. Hasil analisis menunjukan bahwa pemenuhan prinsip kesejahteraan hewan pada pemanfaatan beruk di tempat pelatihan beruk masih belum memadai. Kesejahteraan hewan yang buruk dapat berdampak pada kesehatan dan pemeliharaan hewan tersebut, Macaca nemestrina (beruk) is a type of monkey that has a short tail like a pig-tailed. Therefore, it is often called by pigtail monkey. The International Union for the Conservation of Nature and Natural Resources (IUCN) listed Southern pigtailed macaques into endangered category. One of the uses of Southern pig-tailed macaque was carried out at Beruk training place, Pariaman City. Southern pigtailed macaques were trained to be used as working partners in the coconut plantations. The use of Southern pig-tailed macaques should be appropriate where the wild animals must be kept in an environment that could provide choices for animals to behave the same as in their own habitat. This study aims to determine the principles of animal welfare and the use of Southern pig-tailed macaques at Beruk training place. The collected data will be analyzed and compared to the result of other studies by a descriptive narrative. The five freedoms of animal welfare will be a parameter of Southern pig-tailed macaques’ welfare, namely freedom from hunger and thirst, freedom from discomfort, freedom from pain, injury and disease, freedom from fear and distress, and freedom to express normal behavior. The results of analysis showed that the principles of animal welfares in the use of macaques at beruk training place is not fulfilled. The lack of animal welfare could affect to the animals health and well being

Judul: Positive Reinforcement Training sebagai Upaya Refinement Pemeriksaan Fisik Macaca nemestrina Usia Muda di Kandang Koloni
Abstrak: Beruk (Macaca nemestrina) merupakan satwa primata yang dapat berperan sebagai hewan model dalam penelitian biomedis. Penerapan kesejahteraan hewan dalam pemeliharaan dan penggunaan beruk dapat diterapkan melalui positive reinforcement training (PRT) sebagai upaya refinement dalam pemeliharaan kesehatan, termasuk mendukung tindakan pemeriksaan fisik. Penelitian ini bertujuan membentuk tingkah laku kooperatif pada beruk usia muda untuk memudahkan pelaksanaan pemeriksaan fisik. Penelitian dilakukan pada empat ekor beruk jantan di kandang koloni, dengan melakukan proses habituasi, temperament assessment (TA), pengamatan perilaku dengan metode focal sampling (FS), menggunakan novel object untuk mengidentifikasi potensi hewan untuk dilatih, dan PRT untuk membentuk perilaku yang mendukung pemeriksaan fisik berupa palpasi. Penilaian TA dilakukan untuk mengategorikan temperamen beruk sebagai temperamen open, moderate, dan inhibited sehingga dapat mengkaji potensi hewan untuk dilatih. Tahapan PRT meliputi enam tahap target training, dilanjutkan dengan dua tahap position training. Hasil TA menunjukkan bahwa dua ekor beruk memiliki temperamen open, satu ekor temperamen moderate, dan satu ekor temperamen inhibited. Hasil penelitian menunjukkan bahwa tiga ekor beruk dengan temperamen open dan moderate berhasil mencapai tahap akhir PRT dan satu ekor beruk temperamen inhibited tidak berhasil menyelesaikan PRT. Namun, terlihat adanya inkonsistensi karena sifat beruk usia muda yang playful dan pengaruh faktor distraksi dari sekitar kandang., Pigtailed-macaque (Macaca nemestrina) is a nonhuman primate that is distributed in Southeast Asia. These primates serve as an animal model in biomedical research. Implementation of animal welfare in the care and use of this animal may be through positive reinforcement training (PRT) as a refinement for conducting physical examinations. The objective of this research was to form cooperative behavior in adolescent pigtailed macaques by PRT to facilitate the implementation of physical examinations without restraint. The study was performed on four adolescent male pigtail macaques housed in colony setting. The study comprised of a habituation process, behaviour observation using focal sampling and temperament assessment using novel objects to identify trainability of animals, and PRT to shape behavior that will support palpation examination without restraint. Temperament assessment categorized animals into open, moderate, and inhibited. The result showed that the temperaments of two were open, one was of moderate temperament, and one of inhibited temperament. The training stages in PRT include six stages of target training followed by two stages of position training. The study resulted in three macaques (of open and moderate temperament) completed all training stages where as one macaque (inhibited temperament) did not. The PRT process in adolescent macaques showed inconsistent progress, which may be due to the playful nature of pigtailed macaques at this age and other factors relevant to social grouping setting of the animals.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
