Complete feed (CF) utilization is expected to have impact on higher productivity due to increased intake and digestibility. The objective of research was to evaluate the effects of different level protein of CF based-on fermented ammonization (amofer) rice straw to Simmental offspring intake and digestibility Twenty males Simmental offspring with average live weight 372.15± 26.64 kg (coefficient of variance 7.16%) were used in this study. Feed treatment consisted of BC Nutrifeed 132 concentrate as control feed (T0) and CF based-on amofer rice straw consisted of T1, T2, T3 and T4 which had crude protein content 11, 12, 13 and 14% respectively and also total digestible nutrients (TDN) ± 62%. Completely randomized design with five treatments and four replicates were designed for this research. Data was analyzed by analysis of variance (ANOVA) at 95% significance level. The results showed that different crude protein did not affect the intake of dry matter, organic matter, crude protein and TDN. It was significantly affected the digestibility of dry matter, organic matter and crude protein (p<0.01). The highest digestibility was obtained to treatment with 12% crude protein and ± 62% TDN. Conclusion of this study was different level of crude protein constituted in CF which produced from specific material resource was proven to have impact in increasing cattle’s digestibility.Doi: 10.12777/ijse.4.2.2013.86-91 [How to cite this article: Mayulu, H., Sunarso, S., Christiyanto, M. and Ballo, F.

Publisher : Chemical Engineering Diponegoro University

Forage demand can be supplied from rice straw which processed with certain feed technology innovation. Some advantages can be derived under this technology i.e. increasing nutrient content, optimizing the utilization, improving the efficiency and reducing production cost by minimizing feed cost. Ammoniation fermentation (amofer) as an applied technology could give solution over the limitation of rice straw availability. The objective of this research was to determine the potency of rice straw processed with amofer (amofer-rice straw) as raw material to formulate complete feed. The experiment was carried out with randomized block design with three treatments and six replications. Amofer treatment was carried out by adding urea 3% from the total material and then placed into plastic jar +12 liter and then incubated under an-aerobic process for 18 days. Fermentation material i.e. biology starter by 1% of total material was added at the ninth day. Dry Matter (DM) content resulted from each treatments was 87,28%, 85,96% and 84,61% for T1, T2 and T3, respectively. Crude Protein (CP) content was T1=24,48%, T2=21,04%; and T3=24,46%, Crude Fiber (CF) content was T1=31,30%; T2=31,30%; and T3=31,39%. Total Digestible Nutrient (TDN) for version 1 was T1=57,29; T2=56,19; and T3=56,89 and version 2 was T1=53,11%; T2=52,28%; and T3=51,10%. The average value of Non Nitrogen Free Extract (NNFE) was T1=23,49%; T2=28,08%; and T3=26,57%. The utilization of amofer as applicable technology is considered as the most appropriate method to increase the quality of rice straw by significantly increase nutrient content in term of crude protein (CP) and reduce crude fiber (CF) content. This increasing quality can be seen from the result of proximate analysis, NNFE and TDN content

Publisher : Chemical Engineering Diponegoro University

By-product derived from palm oil plantation and mill is very potential for energy and protein source for ruminant feed. However, it is still underutilized due to low content of crude protein (CP) with high crude fiber (CF). Ammoniation or fermentation technology could optimize the quality of by-product by increasing digestibility, reducing CF and increasing CP content. The objective of this research was to determine the nutrient and potency value of palm oil plantation and mill’s by-product applied with amofer technology for ruminant feed. Sample was prepared in two methods: 1) sample without amofer application, 2) sample with amofer application under anaerobic method and incubated for 18 days. Ammoniation was carried out by adding urea of 3% from the total material and then incubated for nine days. At the ninth day, some microorganisms starter i.e. cellulolytic, amillolytic and proteolytic were added by 1% of the total material. Proximate analysis was carried out in laboratory to examine the nutrient value. The crude protein content at each part of feed material before and after amofer treatment was follow: palm midrib: 3.16%:17%; palm leaves 6.53%:26.51%; empty fruit bunch 7.01%:1673%; palm pressed fiber 5.56%:16.00%. While the crude fiber at each part of feed material was: palm midrib 37.85%:30.86%; palm leaves 30.39%:24.41%; EFB 40.22%:34.98%; PPF 50.39%: 41.70%. The application of amofer could increase the amount of feed material (ton/ha/y): dry matter (DM) 14.82:15.89; CP 0.79:2.87; total digestible nutrient (TDN) 7.63:8.5. Moreover, amofer application could also increase the nutrient content of palm oil plantation and mill’s by-product by increasing CP and reducing CF. This increasing was also followed by the increasing of DM, CP, and TDN which indicated that those feed sources were recommended as ruminant feed material

Publisher : Chemical Engineering Diponegoro University

A development of oil palm pruner and harvester machinery design implemented in the field still faces a problem due to the lack of effective and efficient design which is need to be solved. It was noted that in order to develop the design, an early data and information of physical and mechanical properties of palm oil frond and stem fruits is critically important. The objective of the research was to obtain the physical and mechanical properties of palm oil frond and stem in order to develop the design of pruner and harvester machinery. The result showed that tool machinery was been advantageous by the physical properties of the plant i.e. the total weight of frond and leaf which enable to support the cutting process. The average of total weight of frond and leaf was 16.8 kg. The diagonal cutting trajectory was been more advantageous because of total weight and frond shape toward to the different of the plant tissue area. The measurement result shows that cutting curve follows the time required for cutting. The comparison among cutting curve shows differences in cutting thickness or length. In this case, the thickness is linear with cutting time. Besides, those curves show differences at the height which determine the maximum value of tested material cutting resistance. Alternative solution for machinery development design is pruner-harvester for height plant below 6 m and among 6 to 12 m. For below 6 m, pruner-harvester was designed by incorporating motor as power source and cutter-disc as the knife cutter. That condition was relied on that estate which was maintenance intensively commonly used cutter-disc. Pruner-harvester above 6 m and up to 12 m was improved based on manual egrek-designed by adding fresh fruit bunch alley supply glide in order to keep the fruits still in intact form. The consideration was based on affectivity and efficiency. It also considers homogenous ecological of palm oil plant which should be maintained to reduce global warming effect. Information obtained in this research could become positive consideration and alternative solution to provide problem solvingat early development design of palm oil pruner and harvester machinery.Doi: http://dx.doi.org/10.12777/ijse.4.2.2013.69-74[How to cite this article: Intara, Y.I., Mayulu, H., and Radite, P.A.S.

Ruminants have a complex digestive system so they can utilize forage nutrients to convert them into food products of high economic value (meat and milk) and papaya leaves have the potential to be an alternative source of new feedstuff. The research was conducted at the Laboratory of Animal Feed Chemistry, Faculty of Animal Husbandry, Hasanuddin University Makassar (for proximate analysis), Laboratory of Animal Nutrition and Feed, Faculty of Animal Husbandry, Gadjah Mada University, Yogyakarta (for quantitative and qualitative analysis). The study was used proximate analysis to determine the nutritional content of papaya leaf, in vitro analysis to measure dry matter digestibility (DMD) and organic matter digestibility (OMD), and Thin-Layer Chromatography (TLC) for quantitative and qualitative tests of alkaloid compounds. The results showed that the DMD values of dry leaf and fresh leaf DMD were 72.74% and 78.44%, respectively. The highest score of rations DMD and OMD was R2FPL (69.98%) and R2DPL (61.92%), respectively. A qualitative test of papaya leaf bioactive compounds using UV 254 light obtained 3 spots with a detectable Rf value of 0.72 and a quantitative test with piperine test parameters showed the results of the analysis were "not detected". The results showed that papaya leaves were suitable as an alternative feedstuff for ruminants (cattle, buffalo, goats, and sheep).

Berbagai upaya telah dilakukan untuk meningkatkan produktivitas, produksi maupun populasi sapi potong dalam rangka mendukung program kecukupan daging (PKD) 2010, yang direvisi menjadi 2014. Produksi daging dalam negeri diharapkan mampu memenuhi 9095% kebutuhan daging nasional. Karena itu, pengembangan sapi potong perlu dilakukan melalui pendekatan usaha yang berkelanjutan, didukung dengan industri pakan yang mengoptimalkan pemanfaatan bahan pakan lokal spesifik lokasi melalui pola yang terintegrasi. Hingga kini, upaya pengembangan sapi potong belum mampu memenuhi kebutuhan daging dalam negeri, selain rentan terhadap serangan penyakit. Hal ini dapat disebabkan oleh berbagai kelemahan dalam sistem pengembangan peternakan. Oleh karena itu, perlu diupayakan model pengembangan dan kelembagaan yang tepat berbasis masyarakat dan secara ekonomi menguntungkan. Pemerintah sebaiknya menyerahkan pengembangan peternakan ke depan kepada masyarakat melalui mekanisme pasar bebas. Pemerintah lebih berperan dalam pelayanan dan membangun kawasan untuk memecahkan permasalahan dasar dalam pengembangan peternakan sehingga dapat mengaktifkan mekanisme pasar. Usaha peternakan hendaknya dapat memacu perkembangan agroindustri sehingga membuka kesempatan kerja dan usaha. Implikasi kebijakan dari gagasan ini adalah perlu dibuat peta jalan pembangunan peternakan nasional dan diuraikan secara rinci di setiap wilayah pengembangan ternak.

Meat needs (Broilers) have increased and meat consumption is influenced by consumer preferences caused by shifting consumption patterns, and is supported by low prices compared to beef. The shift is influenced by prices, substitute goods, tastes, season, age, education, number of dependents, income, and increasing population so that preferences, and attributes that consumers consider in buying broiler meat in traditional markets need to be studied. The study used a purposive sampling method, with the criteria of the Adji Dilayas Sanggam Market, Senja Market, and the Milono Market in Berau Regency, having broiler meat traders. Determination of respondents using proportional sampling techniques, each market 12 respondents (36 respondents), meet the smallest number of traders considered to meet the minimum sample criteria. Sources of data obtained from primary data and secondary data. The results showed that broiler meat that has a golden color, clean skin, medium carcass size, physically not bruised, fresh meat, and especially the chest. Chi Square analysis showed that all attributes were significantly different (p <0.05), meaning that there were differences in preferences for the attributes of broiler meat in traditional markets. Fishbein Multiatribute Analysis proves that meat freshness, flesh color, carcass physicality, skin cleanliness, carcass size, and carcass portion are the most considered, and or not considered attributes.
