This study intends to find out the impact of green tea leavesâ€™ concentration and heating temperature on the physical quality of the antimicrobial edible film (AmEF) made from chicken bone gelatin. This study also utilizes chicken bone waste, in oder to increase both monetary value and the usefulness of that waste. The bone gelatin will then be utilized as AMeF and combined with green tea leavesâ€™ extract (Camellia sinensis) that used as sausage wrapper. Several stages have been taken placed as follow: chicken bone gelatin production; green tea leaves extraction; and tea leavesâ€™ extract-AMeF production. cCompletely randomized design with the factorial pattern was used in this study. Data was statistically analyzed using uni-variate analysis with 5% significance rate. Duncanâ€™s Multiple Range Test (DMRT) will later be used to further test if there is a difference between each treatment. The physical qualities of AmEF that tested in this study include clarity, color, and thickness. The result of this study shows that a clarity value of AmEF was ranged between 0.62-2.12 abs, color was 0.87-2.60 abs, and 0.015-0.023 mm of thickness. The addition of tea extract and heating temperature have significant (P<0.05) effect on the clarity and color while have no effect on the thickness.

This study aims to analyze the potential of the sugar mill waste, namely baggase and molasses as a mixture of cow manure as a substrate in a methanogenic fermentation. This study uses 4 treatment that is P0 as controls (100% cow manure), later in other treatment using a mixture of cow manure comparison: baggase: molasses, P1 (50:20:30), P2 (50:30:20) and P3 ( 50: 40; 10). Parameters measured were nitrogen, carbon, ratio C / N and pH value. The analyze used in this research is statistic analysis. The results were obtained P3 which is a mixture of substrate (50:40:10) has an average value of the content of nitrogen, carbon, ratio C / N, and high pH value is compared to the other treatments. Ratio C / N at P3 of 24.47 closest Ratio C / N ideal for methanogenic fermentation which amounted to 25. The pH value of the treatment amounted to 7.05 billion P3 also meet the standards for process fermentation ranging from 6.6 to 7.6.

Ternak domba di Desa Sriharjo masih dipelihara secara tradisional di pekarangan rumah di kandang berlantai tanah. Tujuan dari pengabdian kepada masyarakat ini adalah pendampingan pembuatan kandang domba sehat di Desa Sriharjo, Kecamatan Imogiri, Kabupaten Bantul. Mitra kegiatan pengabdian adalah 30 peternak anggota kelompok ternak Taruna Tani Hijaunya Cinta, desa Sriharjo. Kegiatan yang dilakukan meliputi sosialisasi, pelatihan, studi banding dan dilanjutkan pendampingan peternak membangun kandang sehat. Pemahaman masyarakat terhadap kandang sehat diukur melalui wawancara serta pengisian kuesioner sebelum dan sesudah pengabdian. Hasil pengabdian ini adalah peternak telah berhasil membangun kandang panggung percontohan yang berlokasi di pekarangan yang tidak terlalu dekat dengan rumah penduduk. Hasil survey menunjukkan bahwa sebelum PKM sebanyak 10% dan setelah PKM semua (100%) peternak memahami tentang pengertian dan manfaat kandang sehat. Disimpulkan bahwa kandang domba sehat telah berhasil dibangun dan fungsinya telah dimengerti oleh semua peternak domba di desa Sriharjo.

Tunnel or tubular type of bio-digester has been widely developed in many countries for producing a renewable clean fuel gas named biogas. This digester type only requires minimum maintenance and simple construction for ensuring its lower cost compared to others with similar capacity. Mostly, polyethylene (PE) plastic bag is used for construction materials of the tubular digesters. In this research, the tubular type has been constructed using large diameter PVC (Poly Vinyl Chloride) pipe for increasing the durability and safety. The performance of PVC digesters have been tested by measuring biogas production rate and CH concentration in the gas. COD (Chemical Oxygen Demand) and BOD (Biological Oxygen Demand) drop between inlet and outlet sludge have been measured for examining the digester ef- ficiency. Then, the performance was compared with PE plastic digesters data from several literatures which still needs some improvements for enhancing its capability and performance.

Energy issue, particularly related to fossil fuel, is one the main issues today. Biogas is a new and renewable energy issued in National Research Agenda (ARN) 2010-2014 to overcome the energy crisis problem. A so called purification process is used to remove contaminants in biogas, including H2S in order to improve the standard requirement of biogas application. In this research, H2S concentration in biogas system is measured and monitored by H2S monitoring system.The hardware system comprises of piping and microcontroller AVR 8535 systems while the software system comprises of codes written in Delphi 7.0 and Code Vision AVR Eval. The result of the system is displayed on LCD or computer to enable the monitoring process by operator. The monitoring of H2S sensor responses will be carried out for recycled BFA size of 60+100 mesh and -200 mesh.Experiment has been conducted for sensor warming up time and response time for H2S and CH4 sensor, calibration process for H2S sensor and filter column. Based on sensor calibration experiment, transfer function of TGS825 sensor from calibration is y = 0.0203x + 27.153. The best adsorption model which represents BFA adsorption of biogas from tofu waste in the research is Thomas model.

Kepincangan pada sapi perah yang dapat diebabkan kuku abnormal dapat mempengaruhi kesehatan dan produksi susu. Penelitian ini bertujuan membandingkan kasus kepincangan akibat kuku abnormal pada sapi perah yang dipelihara di kandang dengan alas karet dan beton. Penelitian ini menggunakan 104 ekor sapi perah dari 23 peternak, yang terdiri dari 72 ekor dipelihara dengan alas kandang karet dan 32 beton. Semua sapi diperiksa kukunya, kemampuan berdiri dan berjalan. Hasil penelitian menunjukkan bahwa prevalensi kasus kuku abnormal sebanyak 26 dari 105 ekor sapi (25%) yang terdiri dari 16/72 ekor (22,2%) pada kandang alas karet dan 10/32 ekor (31,3%) pada kandang alas beton. Kondisi kuku tersebut menyebabkan sebanyak 8 ekor sapi (30,8%) kesulitan berdiri atau kesulitan berjalan dan (69,2%) masih dapat berdiri dan berjalan dengan normal. Sebanyak 6/16 ekor (37,5%) sapi pada kandang alas karet dan 2/10 ekor (20%) sapi pada kandang alas beton menunjukkan kesulitan berdiri dan berjalan. Abnormalitas kuku pada penelitian ini kemungkinan disebabkan kuku tidak dipotong tepat waktu karena peternak kurang berpengalaman. Kesimpulan dari peneltian ini adalah prevalensi problem kuku abnormal adalah 25% yang didapatkan lebih banyak terjadi pada kandang alas beton. Kepincangan akibat kuku abnormal terjadi pada 30,8% sapi perah kuku abnormal dan kejadian didapatkan lebih banyak pada sapi yang dipelihara di kandang dengan alas karet.

he experiment was conducted to determine biogas quality produced from mixture of dairy manure and bagasse with different C/N ratio level, and to know the optimal mixture ratio. There were three group treatments based on C/Nratio level : C/N ratio 22, 30, and 35 with three replications each. Nine units of 20 litre batch-feeding digesters were used during 30 days examination. The main data were BOD, COD, pH and VFA values, total biogas volume, andmethane value. C/N ratio of dairy manure and bagasse was 22, 12, and 198. Dry matter mixture was 7%. BOD value was decreased 54.33%, 27.89%, and 42.86%, COD value was decreased 35.85%, 8.29%, and 27.88% and biogas wasproduced as much as 29.42 litre, 68.51 litre, and 114.73 litre by each treatment with methane values of 24.16%, 27.5%, and 23.38%. VFA value were 27.19 ml mol, 27.86 ml mol, and 30.73 ml mol respectively during operation. BOD andCOD value decrease, pH value, biogas temperature, and total biogas volume was different among treatment. The optimal mixture was C/N ratio 30 treatment. The results indicated that bagasse could be used as material mixture in biogas production.(Key words : Biogas, Dairy manure, Bagasse, C/N ratio, Methane)
