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: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
