Judul: Internal and External Analysis of Coffee Value Chain in Bogor Regency
Abstrak: Kopi merupakan salah satu komoditi perkebunan yang berperan strategis dalam perekonomian daerah, khususnya di Kabupaten Bogor. Sebagian besar kopi di kabupaten tersebut diperoleh dari perkebunan rakyat. Adanya peningkatan produksi harus didukung oleh rantai pasok melalui peningkatan rantai nilai kopi. Oleh karena itu, penelitian ini bertujuan untuk mengidentifikasi rantai nilai kopi dan menganalisis kondisi internal dan eksternal rantai nilai komoditas tersebut dengan analisis SWOT. Jenis data yang digunakan adalah data primer dan sekunder. Data primer diperoleh melalui kuesioner dan wawancara ke aktor rantai pasok kopi kemudian dianalisis dengan pendekatan rantai nilai. Selanjutnya analisis internal dan eksternal berupa analisis kekuatan, kelemahan, peluang dan ancaman rantai nilai kopi. Hasil penelitian ini berupa rantai nilai utama adalah aktivitas penanaman dan perawatan kopi yang ditunjang oleh aktivitas pengembangan teknologi untuk pengolahan kopi dari hulu ke hilir. Analisis SWOT dari internal yaitu kelompok tani yang memiliki keahlian pengolahan dan varietas kopi petani telah terakreditasi, sedangkan ekternal yaitu perhatian dan dukungan dari dinas terkait dalam berbagai hal., Coffee is a plantation commodity that plays a strategic role in the regional economy, especially in Bogor Regency. Most of the coffee in the Regency is obtained from smallholder plantations. There are raising production must be backed by supply chain through improving value chain. Therefore, this study aims to identify the value chain and analyze the internal and external conditions of the coffee value chain with a SWOT analysis. The type of data were primary and secondary data. Primary data obtained through questionnaires and interviews with supply chain actors were then analyzed using the value chain approach. Furthermore, internal and external analysis in the form of analysis of strengths, weaknesses, opportunities and threats of the coffee value chain. The results of this study in the form of the main value chain are coffee planting and maintenance activities supported by technology development activities for processing coffee from upstream to downstream. SWOT analysis from internal is farming community have processing skill and faming community’s had have accredited resources that support while external is attention and support from related agencies in various ways.

Judul: Competitiveness Analysis of Robusta Coffee Commodities in Pamijahan District, Bogor Regency, West Java
Abstrak: Kopi merupakan salah satu komoditas perkebunan yang dapat dikembangkan dan menjadi komoditas ekspor perkebunan unggulan Indonesia. Semakin tingginya minat masyarakat untuk menikmati kopi membuat kopi menjadi primadona komoditas perkebunan yang banyak dibudidayakan oleh petani. Hasil produksi kopi haruslah memiliki daya saing agar mampu bersaing dengan kompetitor yang semakin meningkat ditambah dengan adanya kebijakan pemerintah terkait penghapusan Eksportir Terdaftar Kopi (ETK). Tujuan dari penelitian untuk menganalisis keunggulan komparatif dan kompetitif serta dampak kebijakan pemerintah terhadap daya saing usahatani kopi robusta di Kecamatan Pamijahan, Kabupaten Bogor. Metode sampel digunakan untuk mengumpulkan data melalui kuesioner kepada petani kopi robusta. Analisis daya saing menggunakan metode Policy Analysis Matrix (PAM). Hasil penelitian menunjukkan usahatani kopi robusta di Kecamatan Pamijahan memiliki daya saing berupa keunggulan komparatif yaitu DCR diperoleh 0,05 dan keunggulan kompetitif dengan nilai PCR diperoleh 0,05. Dampak kebijakan penghapusan ETK yang berlaku secara keseluruhan memberikan dampak yang positif bagi petani terhadap input, output dan input-output.

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.
