The research methods was using three treatments and four replications. T0 = fermentation of cocoa pod in 10 days, T1 = fermentation of cocoa pod in 15 days, and T2 = fermentation of cocoa pod in 20 days. The mixture was put into a container aerobically. The variables observed were dry matter (DM), crude protein (CP), crude fiber (CF), crude fat (CFt), ash and lignin content. This study was designed using the completely randomized research design with a unidirectional pattern analysis of variance (oneway ANOVA). Significant variables went through Duncan's Multiple Range Test (DMRT). The result showed that the lower lignin content was T2 = fermentation of cocoa pod in 20 days = 6.40 ± 0.12%. It could be concluded that the addition of fungus Pleurotus ostreatus on cocoa pod fermented during 20 days was the lower lignin content in fermentation of cocoa pod.</p> Engkus Ainul Yakin, Sri Sukaryani, Abbas Ummami ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 http://jurnal.unimor.ac.id/JTAST/article/view/601 Fri, 31 Jul 2020 00:00:00 +0000 THE EFFECT OF L-LYSINE HCL SUPPLEMENTATION ON THE BODY WEIGHT GAIN, FEED CONSUMPTION AND FEED EFFICIENCY OF BROILERS http://jurnal.unimor.ac.id/JTAST/article/view/582 <p>The purpose of this study was to determine the effect of l-lysine supplementation in feed on the body weight gain, feed consumption, and feed efficiency of broilers. The experiment was conducted at the Laboratory of Animal Husbandry Study Program, Agriculture Faculty, University of Timor, Kefamenanu from December 2019 to January 2020. This study used 80 day-old chicks (DOC) broilers. The method used is a Completely Randomized Design with four treatments and four replications. The treatments give were: T0 (control feed), T1 (control feed + 0.35% l-lysine), T2 (control feed + 0.70% l-lysine), T3 (control feed + 1.00% l -lysine). Data were processed using Variance Analysis, and Duncan test. The results of the statistical analysis showed that the supplementation of l-lysine in the feed had a significant effect on weight gain, feed consumption, and feed efficiency (P&lt;0.05). It was concluded that supplementation of 0.70% l-lysine HCl in feed gave optimum results to weight gain, feed consumption, and feed efficiency of broilers.</p> Agustina Foni, Charles Venirius Lisnahan, Oktovianus Rafael Nahak ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 http://jurnal.unimor.ac.id/JTAST/article/view/582 Fri, 31 Jul 2020 00:00:00 +0000 MEAT AND FAT COLORS CHARACTERISTICS OF MALE BALI CATTLE FATTENED WITH GREEN FEED IN SMALLHOLDER FARMS http://jurnal.unimor.ac.id/JTAST/article/view/592 <p>The study was conducted for 3 months from March to June 2013,&nbsp;using nine (9) male Bali cattle&nbsp;aged 2.5 - 3.5 years or average&nbsp;3.0 years old based on dental estimates. The initial body weight range was 227-290 kg or an average of 257.40 ± 23.60 kg. Livestock was raising carried out in the Bero Sembada Farmers Group, Laen Manen District, Belu Regency, East Nusa Tenggara.&nbsp;The method used was an experimental method with treatments adjusted for habits of breeders in fattening cattle, which included feed management, housing, and health. The type of feed given during the study was <em>Centrosema pubences</em>, <em>Clitoria ternatea</em>, Fresh <em>Zea mays</em>&nbsp;straw, <em>Pennisetum purpuphoides</em>, <em>Leucaena leucocephala</em>, natural grass,&nbsp;<em>Pennisetum purpureum</em>&nbsp;and&nbsp;<em>Sesbania grandiflora</em>.&nbsp;The variables measured in this study include the color of the meat and fat. Measurement of the color of meat and fat using the standard color of meat and fat issued by the Indonesian National Standardization Agency (SNI: 3932: 2008, Regarding Quality Standards for Carcass and Meat of Beef Cattle). The data collected were analyzed using descriptive statistical procedures. The results of the study showed that male Bali cattle fattened with forage produced a meat color score average of 9.00 or dark red color, while the average fat color score produced was 5.33 or yellowish-white color. It can be concluded that the characteristic color of meat from male Bali cattle fattened with forage on smallholder farms is dark red, while the color of fat is yellowish-white.</p> Paulus Klau Tahuk, Agustinus Agung Dethan, Stefanus Sio ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 http://jurnal.unimor.ac.id/JTAST/article/view/592 Fri, 31 Jul 2020 00:00:00 +0000 THE EFFECT USING OF DIFFERENT COWS MANURE LEVELS AND RICE HUSK ON THE QUALITY OF BIOARANG BRIQUETTES PRODUCED http://jurnal.unimor.ac.id/JTAST/article/view/604 <p>Energi merupakan persoalan yang krusial karena pertumbuahan penduduk yang pesat serta menipisnya cadangan energi. Kebutuhan bahan bakar pun semakin meningkat sehingga energi fosil semakin menipis. Diperlukan inovasi untuk menyediakan bahan bakar alternatif untuk mengatasi kebutuhan energi rumah tangga, salah satu bahan bakar alternatif yang dapat digunakan adalah briket. Briket dapat dijadikan salah satu bahan bakar alternatif yang diharapkan mampu mengatasi krisis energi karena berasal dari bahan yang ada disekitar. Pemanfaatan limbah peternakan dan pertanian merupakan salah satu alternatif yang sangat tepat untuk mengatasi naiknya harga dan kelangkahaan bahan bakar minyak. Pemanfaatan limbah dan penggunaan energi terbarukan perlu dipadukan. Pada penelitian ini bertujuan untuk memanfaatkan limbah menjadi energi terbarukan. Metode yang digunakan dalam penelitian ini adalah&nbsp; rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan yang diulang sebanyak 4 kali. R<sub>1</sub> : Arang kotoran sapi 80% + Arang sekam padi 15% + 5% Tepung kanji, dengan perlakuan R<sub>2</sub> : Arang kotoran sapi 70% + Arang sekam padi 25% + 5% Tepung kanji; R<sub>3</sub> : Arang kotoran sapi 60% + Arang sekam padi 35% + 5% Tepung kanji; R<sub>4</sub> : Arang kotoran sapi 50% + Arang sekam padi 45% + 5% Tepung kanji. Komposisi kedua briket tersebut memiliki masa jenis yang sama (100 g) dengan tekanan 30 kg/cm<sup>2</sup>. Variabel yang diteliti adalah kadar air, kadar abu, laju pembakaran dan nilai kalor. Data yang diperoleh diolah dengan menggunakan sidik ragam sesuai Rancangan Acak Lengkap (RAL) dan uji jarak berganda Duncan. hasil menunjukkan bahwa penggunaan kotoran sapi dan sekam padi dengan level yang berbeda berpengaruh nyata (P&lt;0,05) terhadap variabel yang diteliti. Disimpulkan bahwa bahwa penggunaan 50% arang kotoran sapi, 45% arang sekam padi, dan 5 % tepung kanji menghasilkan kualitas briket terbaik dengan nilai kadar air 3,11%, kadar abu 23,72%, laju pembakaran 0,26 g/detik dan nilai kalor 1247 kal/g.</p> Gerson Frans Bira, Paulus Klau Tahuk, Yosef J.

The experiment was conducted at the Laboratory of Animal Husbandry Study Program, Agricultural Faculty, University of Timor, Kefamenanu from December 2019 to January 2020. The experiment used 80 fourteen-day broilers. The method used in this research was an experimental method with a completely randomized design (CRD) consisting of 4 treatments and 4 replications. The treatments given were: T0 (control feed), T1 (T0 + 0.30% dl-methionine), T2 (T0 + 0.50% dl-methionine), and T3 (T0 + 0.70% dl-methionine). The variables observed were body weight gain, feed consumption, and feed efficiency. The results of the experiment showed that the treatment significantly affected the body weight gain, feed consumption, and feed efficiency of broilers (P&lt;0.05). It was concluded that commercial feed supplemented with dl-methionine by 0.70% increased the growth performance of broilers.</p> Deddyano Kandido Son, Charles Venirius Lisnahan, Oktovianus Rafael Nahak ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc-sa/4.0 http://jurnal.unimor.ac.id/JTAST/article/view/583 Fri, 31 Jul 2020 00:00:00 +0000
