Judul: Study on the Supply Chain of Sweet Potato Flour Industry
Abstrak: Indonesian people are well known in consuming rice as their staple food. As the national food security becomes very demanding on the rice sufficiency, this situation is growing a problem as rice supply is becoming limited. The government has actually made a serious effort to solve this problem by establishing food diversification programs, such as developing flour agro industry based on local commodities to support the national food security. One of the most potential local commodities of carbohydrate source is sweet potato, as Indonesia is the 4th biggest sweet potato producer in the world (FAO 2007). The implementation of supply chain management in developing the sweet potato flour agro industry is becoming very important. Various parties will be involved in this industry, their requirements need to be fulfilled, and their expectations need to be satisfied. Starting from the farmers producing sweet potato tubers, until the industry producing the sweet potatoes flour. Managing supply chain is about meeting supply to demand, to result higher supply chain surplus among all the parties involved so that this agro industry is hopefully becoming attractive for the parties involved. This research is presenting the characteristic of sweet potato, sweat potato flour, and its potency as the raw material for food industry. The present condition of sweet potato business and sweet potato flour supply chain was also studied, taking West Java as a sample case of study. And as an addition, an efficient supply chain management of sweet potato flour agro industry is designed to become a recommendation, or one of consideration for building the sweet potato flour agro industry. According to this research, sweet potato has good potency to be the raw material of flour industry, but the present supply chain needs to be improved to get the optimum result and advantage.

Abstrak: Sweet potato productivity is not balanced with proper utilization. The current utilization sweet potato in Indonesia are still many processed into refined products household. Sweet potato potential can be maximized when processed into semi-finished materials that sweet potato flour is more economically valuable. Sweet potato flour industry has not been quite a lot and still dominated by small and medium industries. Problems which are commonly among other processed that are not hygienic, fluctuating product quality, and sewage treatment potluck. The problems is caused by there is no awareness of owners implement systems plant layout. This research aims to make the design plant layout of the processing plant sweet potato flour that has layout and material flow so that the process is faster dan tidy. The research is divided into two stages, the planning and implementation stages of the design plant layout. Design of plan layout made at the planning stages. From the design plant layout then caried out the aplication form of trial production. Ends with technological analysis and product analysis. Result of the analysis set Ciampea worthy as the plant site. Based on the selection process of the production and selection of equipment generating plant with an installed capacity of 107 kg/day and a maximum capacity of 214 kg/day. Design the layout using a systemic approach to see the connection between the activity and the relationship between space. The result of design layout is factory site plan along with the material flow from the receipt of raw materials to product storage (Lampiran 5). Based on the result of product analysis indicates that the product has been produced according to the standard flour products dan standard sweet potato flour product in Indonesia.

Judul: Posisi Filogeni Orlitia borneensis dan Hieremys annandalei (Testudines) Berdasarkan Gen 16s rRNA
Abstrak: Urutan DNA mitokondria (mtDNA) banyak digunakan sebagai penanda molekuler dalam menentukan hubungan filogeni suatu organisme karena struktur organisasinya yang stabil. Seiring dengan kemajuan bioteknologi, pengelompokkan kura-kura Bataguridal masih menjadi perdebatan. Hal ini disebabkan oleh perbedaan karakter yang diamati. Beberapa hasil penelitian mengelompokkan kura-kura ini ke dalam famili Emydidae tetapi ada yang menempatkan kurakura ini ke dalam famili tersendiri yaitu famili Bataguridae. Pada penelitian ini digunakan urutan nukleotida gen 16S rRNA O. borneensis dan H. annandalei (Testudines) yang disejajarkan dengan urutan nukleotida beberapa spesies Testudines lainnya yang terdapat di Genbank. Hasil rekonstruksi pohon filogeni berdasarkan urutan nukleotida 16S rRNA menunjukkan bahwa O. borneensis dan H. annandalei berkerabat dengan Chinemys reevesi (famili Bataguridae). Hasil amplifikasi gen 16S rRNA O. borneensis dan H. annandalei menunjukkan komposisi nukleotida didominasi oleh nukleotida adenin dan timin dengan nilai perbandingan antara A/T dan G/C = 60.1%:39.9% untuk O. borneensis dan 63%:37% untuk H. annandalei. Rasio transisi terhadap transversi (ts/tv) gen 16S rRNA berkisar antara 0.67 sampai dengan 6.75. Nilai jarak genetik terkecil terjadi antara Trachemys scripta dan Chrysemys picta dan antara Dogania subplana dan Tracemys scripta yaitu sekitar 0.005 sedangkan nilai jarak genetik terbesar terjadi antara Pelomedusa subrufa dan Emydura subglobusa yaitu sekitar 0.869.
