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: Analisis Sistem Pemasaran Beras Ciherang di Kecamatan Cibeber, Kabupaten Cianjur
Abstrak: Rice is the basic commodity that became the staple food for the Indonesian. The purposes of this research were analyzing marketing channels, function, structure and marketing institutions of farmer Ciherang Variety in Cibeber Subdistrict. Beside that, the purposes of this research were analyzing the marketing efficiency by marketing margin, farmer’s share and benefit cost ratio approaching. The research was conducted in 3 villages that are Cisalak, Karangnunggal, Salamnunggal with 30 farmers as the respondents and there are 7 marketing institutions in the subdistrict. Generally, the market structure in this subdistrict is oligopsonistic . Based on the marketing function and the profitable ratio about marketing cost, the channels that through farmers-middlemen-major collector and rice mills in village-retailer-consumer rice in Jakarta is the most efficient channels. The farmer should have made farmer groups or cooperation as part of the marketing system to improve the bargaining position and easier capitalization like through the warehouse system in Cianjur.

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.
