Judul: Analisis Rantai Pemasaran Beras IR-42 (Distribusi dari Kabupaten Subang Ke DKI Jakarta)
Abstrak: Subang in Pasar Induk Beras Cipinang, DKI Jakarta, is known as the supplier of IR-42 rice. IR-42 is one of premium rice ini Indonesia that the price of this rice is higher than the other. However, benefits of the high price of this rice is not earned equally by all actors in the marketing chain. In the other hand, the benefit of the high price of the rice is not The objective of this study is to analiyze the caharacteristics of the IR-42 rice marketing chain from Subang Region to DKI Jakarta, and also to analyze the marketing efficiency rate of the rice marketing chain from Subang to Pasar Induk Beras Cipinang. The characteristics of this marketing channel is analyzed by the supply chain frame work developed by Vorst (2006). While, the analysis of the marketing efficiency is used because it is not possible to measure its performance by the supply chain performance, because there is no supply chain network in this marketing chain.The result of this study indicates that the integrated channel is more efficient than any channel. Developing this marketing channel is important, especially related to its coordination and collaboration among all the actor in this marketing channel

Judul: Kajian Distribusi Beras di Wilayah DKI Jakarta Melalui Pasar Induk Beras Cipinang.
Abstrak: DKI Jakarta is classified as rice consumer area based on its deficiency in rice production as compared to the number of population. Therefore, its dependency to other food producer area, particularly rice producer area, is relatively high. This condition leads to a mutual interaction in food/rice distribution between DKI Jakarta and its surrounding areas. Government of DKI Jakarta has appointed Pasar Induk Beras Cipinang/Cipinang Rice Market (PIBC) as the rice distributor in Jakarta Area. PIBC is managed by a local-owned enterprise, PT. Food Station Tjipinang Jaya, that maintains food security (rice) in Jakarta Area. As a main rice market in Jakarta Area, PIBC controls rice price stability in Jakarta and it will influence the price directly or indirectly in other areas. Price fluctuations often occur and tend to be seasonal due to supply and demand pressures during certain period. Because of inefficiency in rice distribution channels, there is a large disparity between producers and consumers prices. This study aims to: 1) analyze the rice distribution in Jakarta area through PIBC, 2) analyze the spatial interaction of rice distribution between regions, that is from the hinterland to PIBC in Jakarta, to identify the producer area that having the highest driving force, 3) analyze the land carrying capacity in the producer area, 4) analyze the patterns of price data and the level of revenue distribution obtained by farmer in the highest driving force areas, and 5) formulate the policy direction of agricultural sector and rice distribution in DKI Jakarta. Rice distribution mapping was made based on income and expenditure data of PIBC in 2011 and 2012 and treated with spatial analysis using geographic information system applications, while marketing flow and the involved institutions were obtained from interviews with entrepreneurs in PIBC and literature study. Analysis of interaction between regions is carried out using gravity model analysis. The information on the area that has the highest driving force to send its rice production to Jakarta was obtained from the analysis of interaction between regions. Based on these results, an analysis of the land carrying capacity in the rice production area was conducted to determine its ability to further supply the rice to Jakarta. The analysis of price data patterns was performed to reveal the price fluctuations and the price disparity between farmer and consumers prices. The analysis of marketing margins and the farmer's share was used to determine the efficiency of the rice marketing from producers to consumers. The analysis result shows that the marketing flow/rice distribution in Jakarta through PIBC involving various marketing institutions such as local merchants as supplier to PIBC, an agent in the Jakarta area, and retailers consisting of retailers in the supermarket, housing, and traditional markets in Jakarta. The rice supply to the PIBC comes mainly from West Java namely Karawang, Bandung, Cianjur, Cirebon, and Serang-Banten. The rice distribution from PIBC to Jakarta area reached 49 percent of PIBC total expenditures in 2012 with the highest spread in East Jakarta, followed by West Jakarta, South Jakarta, North Jakarta, Central Jakarta and the Thousand Islands respectively. Based on spatial interaction analysis,

Judul: Synthesis of Apatite - Chitosan Composite Using Duck Eggshell and Chitosan with Temperature and pH Control
Abstrak: Composite of apatite-chitosan was prepared by using chitosan as polymer matrix. Calcium phosphate was prepared from CaO and (NH4)2HPO4, which the ratio Ca : P had to be 1.67. Chitosan is produced by deacetilase from biopolymer chitin. Duck eggshell (95% CaCO3) as starting material was converted to be calcium oxide (CaO) through calcinations with temperature 1000oC for 5 hours. In-situ and ex-situ methods were prepared from apatite and chitosan (dissolved with acetate acid 2%). Calcium phosphate prepared for bone implantation, but it is too fragile and brittle to be implant into the body. So addition of chitosan can decrease crystalinity and increase mechanic characteristic (tougher). Composite apatite-chitosan was resulted by fast precipitation. Fast precipitation was held in a breaker glass with nitrogen atmosphere, under controlled temperature at 37oC and pH 7, in order to increase amount of hydroxyapatite. Precipitation with CaO which was dropped by (NH4)2HPO4. Hydroxyapatite and chitosan were appearing at samples with in-situ and ex-situ methods which indicating by peak matching of XRD (closed lattice parameter, crystal size), overlapping at FTIR spectra and supporting by SEM picture (homogenous and agglomerated particle). However, it still needs further research to examine biocompatibility osteoconductive degree of sample by in-vivo and in-vitro test.
