Penelitian ini bertujuan untuk mengetahui manajemen pakan ternak sapi potong di peternakan rakyat di Desa Sejaro Sakti Kecamatan Indralaya Kabupaten Ogan Ilir. Metode yang digunakan dalam penelitian ini adalah metode survei yang terdiri dari data primer dan data sekunder. Data primer diperoleh langsung di lapangan melalui wawancara dengan setiap peternak sapi potong, sedangkan data sekunder didapat dari instansi-instansi yang terkait. Data yang diperoleh kemudian diolah dan disajikan dalam bentuk deskripsi dan gambar. Hasil yang didapat selama pelaksanaan yaitu jenis ternak sapi yang dipelihara di desa ini adalah sapi Bali dan sapi Peranakan Ongole. Manajemen pakan yang diterapkan peternak masih belum tepat, di mana ternak hanya digembalakan untuk mencari makan sendiri pada siang hari, jumlah pakan yang diberikan belum memenuhi kebutuhan, ternak tidak diberi pakan berupa konsentrat, serta frekuensi dan cara pemberian pakan yang belum tepat. Kesimpulan dari penelitian ini adalah peternak rakyat di Desa Sejaro Sakti belum menerapkan manajemen pakan yang baik terhadap ternak sapi potong.Kata kunci: Desa Sejaro Sakti, Indralaya, Kabupaten Ogan Ilir, manajemen pakan, Sapi Potong ABSTRACTThis study aims to determine the management of beef cattle feed on people's farms in Sejaro Sakti Village, Indralaya District, Ogan Ilir. The method used in this study is a survey method consisting of primary data and secondary data. Primary data was obtained directly in the field through interviews with each beef cattle breeder, while secondary data is obtained from relevant agencies. The data obtained is then processed and presented in the form of descriptions and figure. The results obtained during the implementation of the type of cattle kept in this village are Bali cattle and Ongole Breeds cattle. Feed management applied by farmers was not the intensif system, where livestock was only grazed to feed themselves during the day, not given concentrated feed, as well as the frequency and method of feeding are not appropriate. The conclusion of this study is that community farmers in Sejaro Sakti Village have not applied good feed management to beef cattle.Key words: Sejaro Sakti Village, Indralaya, Ogan Ilir, Feed Management, Beef Cattle

Abstract. Pujiastuti Y, Arsi, Sandi S. 2020. Characteristics of Bacillus thuringiensis isolates indigenous soil of South Sumatra (Indonesia)  and their pathogenicity against oil palm pests Oryctes rhinoceros (Coleoptera: Scarabaeidae). Biodiversitas 21: 1287-1294. Bacillus thuringiensis is a gram-positive, entomopathogenic bacterium that could be isolated from soil and be used to control various plant pests. Oryctes rhinoceros is an important pest in oil palm. Application of B. thuringiensis-based bioinsecticides is an alternative in controlling these pests. The purposes of this study were to isolate and identify B. thuringiensis bacteria from the soil of South Sumatra, production of B. thuringiensis-based bioinsecticides and to test their toxicity to O. rhinoceros larvae. The study was conducted in several cities/districts in the province of South Sumatra. Soil samples were taken from various habitats and B. thuringiensis isolates were grown on NGKG agar media. Among 76 soil samples (6 districts and 2 cities) B. thuringiensis colonies were obtained leading to 24 isolates of B. thuringiensis. Toxicity screening tests for armyworm Spodoptera litura were 55.79% (53 isolates) and their mortality to 25.26% O. rhinoceros larvae (24 isolates). From these isolates whose effectively killed O. rhinoceros larvae, 10 isolates were taken and propagated with Nutrient Broth (NB) and biourine enriched with 5% molasses. Number of spores produced was counted during 24, 48 and 72 hours. Furthermore, a bioassay test was carried out on O. rhinoceros larvae for 7 days. Isolate of KJ3P1 caused the highest mortality of O. rhinoceros larvae after 7 days of observation. SDS Page resulted in KJ3P1 and KJ3R5 isolates showing several bands whose content of various types of protein molecular weight. Isolation of B. thuringiensis in South Sumatra produced 2 isolates potentially to be active ingredients in production of bioinsecticides which were effective in killing O. rhinoceros larvae.

Tujuan penelitian ini adalah untuk  mengetahui kualitas serat kasar, lemak kasar dan BETN terhadap lama penyimpanan wafer rumput kumpai minyak dengan  perekat karaginan. Penelitian ini dilaksanakan di Laboratorium Nutrisi dan Makanan Ternak Program Studi Peternakan, Fakultas Pertanian, Universitas Sriwijaya selama 2 bulan dari bulan November sampai Desember 2014.  Penelitian ini menggunakan Rancangan Acak Lengkap yang terdiri dari 4 perlakuan dan 5 ulangan. R1 (wafer rumput kumpai minyak dengan perekat karaginan penyimpanan 0 minggu), R2 (wafer rumput kumpai minyak dengan perekat karaginan penyimpanan 2 minggu), R3 (wafer rumput kumpai minyak dengan perekat karaginan penyimpanan 4 minggu) dan R4 (wafer rumput kumpai minyak dengan perekat karaginan penyimpanan 6 minggu).  Parameter yang diamati adalah kadar serat kasar, lemak kasar dan BETN. Hasil penelitian ini dapat disimpulkan bahwa wafer rumput kumpai minyak dengan perekat karaginan dapat dipertahankan kualitasnya selama 6 minggu penyimpanan (R4). Wafer tersebut tidak berpengaruh nyata (P>0,05) terhadap kadar serat kasar, lemak kasar dan BETN dengan kandungan serat kasar (17,99%), lemak kasar (8,84%) dan BETN (36,75%).

Liquid smoke is one of the feed additive that can be given to animals. The aim of the study was to determine the influence of liquid smoke given through drinking water on meat quality and production of fecal ammonia in broiler. Variables observed were meat pH, water holding capacity, cooking loss, the tensile strength of meat, cut off strength of meat, blood urea nitrogen and creatinine concentrations, and fecal ammonia. The experiment was assigned in a completely randomized design with 5 treatments, and 4 equal replicates. The treatments tested were symbolized as R0, R1, R2, R3, and R4, based on the level of liquid smoke added into drinking water (v/v) namely, 0%, 0.25%, 0.50%, 0.75%, and 1.00%, respectively. The data were subjected to analysis of variance, and continued to Duncan's multiple range test to determine the difference between treatment mean values at 5% probability. The results indicated that addition of liquid smoke up to 1% did not affect the meat pH, water holding capacity, cooking loss, the tensile strength of meat, blood urea nitrogen, and creatinine content, but it decreased the cut off strength of meat and fecal ammonia. It was concluded that an optimal dose of granting liquid smoke through drinking water was 1%.

Tujuan penelitian ini untuk mengetahui kecernaan secara in vitro wafer ransum komplit dengan menggunakan bahan perekat yang berbeda.  Penelitian ini dilakukan di laboratorium Nutrisi dan Makanan Ternak Program Studi Peternakan Fakultas Pertanian Universitas Sriwijaya pada bulan November - Desember tahun 2014.  Rancangan yang digunakan pada penelitian ini adalah Rancangan Acak Lengkap (RAL) yang terdiri atas 5 perlakuan dengan 4 ulangan yang terdiri dari RK (ransum komplit + karagenan 2%), RG (ransum komplit + gaplek 5%), RO (ransum komplit + onggok 4%) dan RT (ransum komplit + tapioka 5%).  Parameter yang diamati adalah Koefisien cerna Bahan Kering, Koefisien cerna Bahan Organik, Konsentrasi N-NH3, dan Konsentrasi VFA.  Hasil penelitian menunjukkan bahwa wafer ransum komplit dengan bahan perekat yang berbeda berpengaruh sangat nyata(P<0,01) terhadap Koefisien cerna Bahan Kering, Koefisien cerna Bahan Organik, Konsentrasi N-NH3, dan Konsentrasi VFA. Kesimpulan dari hasil penelitian ini bahwa uji in-vitro wafer ransum komplit dengan bahan perekat tapioka mampu meningkatkan Kecernaan Bahan kering (KcBK) sebesar 5,28%, Kecernaan Bahan Organik (KcBO) 3,48% dan konsentrasi Asam Lemak Terbang (VFA) 9,902 mM, dan N-NH3 1,2 mM secara in-vitro.
