Abstrak: The smallscale domestic beef catte producers have supplied only 70 percent of the national neeed (Ditjennak 2008).This condition potentially caused problem to meet the increasing demand of beef. Smallholder farmers have special characteristics that raise livestock traditionally with a limited scale. The existence of such characteristics can cause problems in the beef marketing chain. Domestic beef marketing chain in Indonesia is identified as a long marketing chain by the number of middlemen. Many market participants from centers of production to centers of consumption causes the magnitude margins and high transaction costs. Thus, the performance of marketing system is inefficient and lead to higher beef prices. Value chain analysis is an analysis that summarizes the marketing activities and the ability of the institutions supporting marketers in accessing environment. The most important thing in the value chain analysis is a relationship management / coordination among the actors of the starting raw material to the finished product. One strategy that can improve the quality of the relationship / coordination is a partnership. With the partnership, the chain becomes shorter marketing so that value chain performance can be improved. Therefore, the purpose of this study is to: 1) describe the role of the value chain of the beef marketing chain formation, 2) analyze the role of marketing partnerships on the performance of actors in the value chain of beef cattle, 3) analyze the cost structure and marketing margins are formed in chains value of beef cattle. The research was conducted in the District Wanayasa, Banjarnegara, Java Tengah.Peternak selected based on the scale of effort, time and transactions made during the transaction. The analysis used is the value chain model adapting Kaplinsy & Morris (2000). The first phase of the analysis is the entry point of analysis is the analysis of the business characteristics of the cattle farmers, the next is the mapping value chain, in this analysis mapped marketing channels and institutions or actors involved, the final analysis is the analysis of value chain performance (performance) that analyzes the performance of actor in accessing supportive environment and marketing efficiency was calculated through marketing margins, farmers share, a matter of profit / cost, and the ratio R / C. Based on the analysis of the characteristics of farmers (entry point), farmers are not partnered cattle ranchers seek independent both of production and marketing, so that all risks and benefits borne alone. Parnership farmers are keeping cattle, meanwhilethe other party provided the capital such as breeding . System developed in partnership Wanayasa District is rowdy or systems can be classified as a partnership Operational Sustainability (KOA). In tis partnership type, there are to parties, farmers and capital owner. Capital owner is a big farmers/traders who provide cattle and guarantee the marketing of beef cattle. Meanwhile farmers obligate to provide input of beef cattle farming and sell cattle to te capital owners. Furthermore, the characteristics of both farmers who work in partnership system and farmers who do not work in the partnership scheme vii specify the number of partner agencies and the length of the channel is formed.

Judul: Efficiency Analysis of Beef Supply Chain at Bogor City
Abstrak: Daging sapi merupakan produk unggulan komoditas ternak karena dikonsumsi oleh masyarakat luas. Analisis rantai pasok daging sapi dilakukan dengan analisis kualitatif dan kuantitatif. Analisis kualitatif dilakukan dengan menggunakan pendekatan Food Supply Chain Networking (FSCN) yang terdiri dari analisis sasaran rantai pasok, struktur jaringan rantai pasok, manajemen rantai pasok, sumber daya rantai pasok, dan proses bisnis rantai pasok. Analisis kuantitatif dilakukan untuk mengetahui efisiensi dari rantai pasok dengan menggunakan perhitungan marjin pemasaran dan farmer’s share. Hasil analisis kuantitatif adalah saluran 1 yang beranggotakan peternakan – penggemukan – pedagang besar – pedagang kecil – konsumen merupakan saluran pemasaran paling efisien dengan marjin pemasaran 78% dan farmer’s share 22%. Saluran 5 yang beranggotakan peternakan – penggemukan – pedagang besar – industri pengolahan – pedagang kecil – Hotel, Restoran, dan Katering (Horeka) – konsumen merupakan saluran pemasaran yang paling tidak efisien dengan marjin pemasaran 83% dan farmer’s share 17%. Maka dari itu, untuk mengetahui kondisi rantai pasok lebih lanjut diperlukan observasi langsung dan kordinasi dengan pihak-pihak terkait.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
