Judul: Evaluation of Goat Welfare with AWIN in the Bontil Group Livestock
Abstrak: Penerapan kesejahteraan ternak pada peternakan rakyat perlu dilakukan untuk meningkatkan produksi dan produktivitas peternakan. Penelitian ini bertujuan mengevaluasi kesejahteraan ternak kelompok ternak Bontil Grup di Kabupaten Ponorogo. Penelitian menggunakan dua perlakuan yaitu periode laktasi (L) dan non laktasi (NL) masing-masing tujuh kandang. Jumlah kambing L 55 ekor dan NL 46 ekor. Data dianalisis menggunakan analisis uji-t untuk data parametrik dan dilakukan analisis deskriptif kualitatif. Penilaian Animal Welfare Indicator (AWIN) meliputi penilaian berbasis ternak diantaranya cacat tanduk, abses, berlutut di rak pakan, kondisi rambut, oblivion, stress termal, latensi kontak pertama, dan kelumpuhan. Penilaian individu ternak yaitu feses, panjang kuku, ambing tidak simetri, kotoran mata dan kotoran hidung. Hasil analisis menyatakan bahwa terdapat perbedaan nyata pada indikator kotoran mata (P<0,05). Kandang laktasi memiliki nilai yang baik pada indikator kotoran mata, sedangkan pada kandang non laktasi baik pada kondisi rambut, latensi kontak pertama, panjang kuku, dan ambing tidak simetri. Kondisi kesejahteraan ternak di Bontil Grup termasuk baik, akan tetapi perlu ditingkatkan pada aspek indikator kotoran mata, kondisi rambut, latensi kontak pertama, panjang kuku, dan ambing tidak simetri., The application of livestock welfare on smallholder farms needs to be done to increase livestock production and productivity. This study aims to evaluate the welfare of livestock in the Bontil Group livestock group in Ponorogo Regency. The study used two treatments, lactating (L) and non lactating (NL) goats, each with seven pens. The number of goats is L 55 and NL 46. Data were analyzed using t-test analysis for parametric data and qualitative descriptive analysis was performed. The Animal Welfare Indicator (AWIN) assessment includes livestock-based assessments including horn defects, abscesses, kneeling on the feed rack, hair loss, oblivion, thermal stress, first contact latency, and paralysis. The individual assessment of livestock is feces, nail length, asymmetrical udder, eye discharge and nose discharge. Significant differences were determined at P<0.05. The results of the analysis stated that there was a significant difference in the eye discharge indicator (P<0.05). The lactation cage had good scores on the eye discharge indicator, while the non-lactation cage had good hair conditions, first contact latency, nail length, and asymmetrical udder. The welfare condition of livestock in the Bontil Group is good, but needs to be improved on the indicators of eye discharge, hair fur, first contact latency, nail length and asymmetrical udder.

Judul: Evaluation of Animal Welfare Aspect at Jonggol Animal Science Teaching and Research Unit (JASTRU)
Abstrak: Penerapan aspek kesejahteraan hewan (Kesrawan) dalam pemeliharaan ternak domba dapat meningkatkan performa ternak yang dipelihara. Penelitian ini bertujuan mengevaluasi penerapan aspek kesejahteraan hewan pada ternak domba yang dipelihara berbasis padang penggembalaan di Unit Pendidikan dan Penelitian Peternakan Jonggol (UP3J). Metode penelitian dilakukan melalui observasi dan wawancara dengan analisis data secara deskriptif. Hasil penelitian menunjukkan tingkat kesejahteraan ternak domba dalam kategori normal berdasarkan penilaian prinsip good feeding, good housing, good health, dan appropriate behavior sesuai panduan Animal Welfare Indicator (AWIN). Penerapan penilaian pada good feeding diperoleh Body Condition Scores (BCS) ternak dengan skor 3 dan 4 (kondisi ternak gemuk). Selanjutnya, terkait indikator bak minum di dalam kandang, terdapat 8 tempat minum dengan 62% dalam kondisi bersih dan 37% kondisi sebagian kotor. Indikator Good housing menunjukkan kondisi wol dan kuku dalam kondisi normal, serta laju respirasi domba dalam keadaan normal. Indikator Good Health menunjukkan domba dalam keadaan normal, yaitu tidak terdapat luka, cedera dan tidak menderita sakit. Sedangkan pada indikator Appropriate behavior diperoleh kondisi ternak domba dalam keadaan normal (skor 2). Data menunjukan bahwa penerapan aspek kesejahteraan hewan di UP3J jonggol dalam kategori baik/cukup dan Sumber Daya Manusia (SDM) di Unit Pendidikan dan Penelitian Peternakan Jonggol (UP3J) secara umum telah memahami konsep kesejahteraan hewan., Animal welfare aspects (Kesrawan) in sheep husbandry can improve the performance of the animal. This study aims to evaluate the application of animal welfare aspects on sheep husbandry at JASTRU farm. The research method was carried out through observation and interviews, and the data was analyzed descriptively. The results showed that the welfare level of the sheep was in the normal category based on the assessment of the principles of good feeding, good housing, good health, and appropriate behavior according to the Animal Welfare Indicator (AWIN) guidelines. The application of assessment on good feeding obtained Body Condition Score (BCS) for cows with a score of 3 and 4 (fat sheep condition). Furthermore, regarding the drinking tub indicator in the housing, there are 8 drinking places with 62% clean conditions and 37% dirty conditions. The Good housing indicator shows the condition of the wol and hooves under normal conditions, as well as the respiration rate of the sheep under normal conditions. The Good Health indicator shows that the sheep are in normal condition there are no cuts, wounds and no pain. While on the indicators of appropriate Behavior, the condition of the sheep is in normal condition (score 2). The data shows that the application of animal welfare aspects on JASTRU farms is in the good/adequate category and Human Resources (HR) in JASTRU farms generally understand the concept of animal welfare.

Judul: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
