Judul: The Development of Management System of Beef Logistics in Jakarta.
Abstrak: Tingginya konsumsi daging sapi oleh penduduk DKI Jakarta dan tidak adanya populasi sapi potong di DKI Jakarta menjadikan DKI Jakarta sebagai pasar utama daging sapi (Deptan, 2004). Dalam upaya pemenuhan kelancaran pasokan daging sapi di DKI Jakarta, terdapat beberapa masalah, antara lain : (I) masih belum terkendalinya seluruh pemenuhan daging sapi !rnta, secara aman layak dan sehat; (2) belum tertatanya seluruh jalur distribusi, sehingga menyebabkan ekonomi biaya tinggi; dan (3) masih kurangnya kelancaran distribusi pada hari-hari besar, sehingga menyebabkan ekonomi biaya tinggi. Berdasarkan hal-hal tersebut di atas, maka penelitian ini difokuskan pada permasalahan, antara lain : (1) masih belum optimalnya ptran kelembagaan di dalam supply chain untuk memenuhi daging sapi di Kota Jakarta secdara aman, layak dan sehat, (2) masih belum adanya sistem pengambilan keputusan secara cepat untuk memenuhi kebutuhan daging sapi di Kota Jakarta., One of the problems faced by Jakarta city is the availability of beef supply, especially healthy beef, safo and lawful. Jakarta needs logistics network of healthy heefto develop highly strong mechanism of food. The pattern and mechanism of livestock supply from the source countryside and the request of beef consumption by the people of Jakarta is one of the distribution in che supply chain management of beef in Jakarta. Unfortunately, until now there is still no beef logistic model which supplies the beef continually and controlled. However, there is no quick decision making tools available recently in fulfilling the beef requirements. The supporting model of the management of beef logistics in DKI Jakarta consists of three factors which are suplier model, consumer model and focal company model based on using analysis hierarchi process (AHP) methode to choose the priority of strategy by using the quality, cost, and delivery (QCD) indicators. These models are joined in supply chain management and assumption model to gain the minimum total cost. This formula model was used to count the minimum cotal cost in the combination of transportation concept, distribution, lint: system and inventory concept.

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.
