Abstrak: West Lampung Regency has a great potency in agricultural sector. The dominant commodities which developed by the people were: coffee, pepper, clove, oil palm and coconut. The value added of whole products are very low because there are no agroindustries. So that the regency government will build the integrated agribusiness area development based on coconut commodity. The pusposes of the research were: 1) to identify the potential location, 2)to identify the prospective products, 3)to identify the public opinion, 4) to identify the prospect of market and 5) arrange the direction of development. The research was conducted in coastal district of West Lampung Regency on January-Marh 2008. This study used Scalogram, LQ, Land suitability Analysis. The results of those analysis were overlaid to find the alternative location. The choosing of prospective products using Analytical Hierrarchy Process (AHP) with expert respondent on coconut agoindustry. Chain of marketing, Industrial Tree, and Trend Analysis were used to describe the market prospect of coconut products. The result showed that there are 3 potential locations, group of villages Biha, Marang, Sumber Agung, and Negeri Ratu Ngambur, group of villages Way Redak, Kampung Jawa, Pasar Krui, Seray, and Walur, and The Third alternative : group of villages Pardasuka, Pagar Bukit dan Sukanegara. Coconut Oil and Dessicated Coconut were the first and second prospective products. Another prospective produtcs were Carbon Active Coco Milk and Coir Fiber. There are 3 level of collecting traders from village, district until sending trader, and the sending trader enjoyed the biggest profit. Projection trend showed, that export tend to increase. Public perception (farmers and traders) showed that farmers in district of Bengkunat, Pesisir Selatan, Pesisir Tengah and Karya Penggawa know better about (Kawasan Usaha Agro Terpadu ) KUAT program than Pesisir Utara and Lemong district. It was caused by the distant of location and the infrastructure. The direction of development based on 3 alternative location, choosen product which requires tight quality handled by KUAT Management, on the other hand the side products are handled by farmers/group of farmer. All the activities are designed in a cluster which including many stakeholders participation.

Judul: Dynamical System of Hepatitis B in Three Groups with Vaccination
Abstrak: The aim of this study is to modify the hepatitis B transmission model in three age groups involving vaccination from the model conducted by Zhoe and Zhang.The method used is to analyze the stability of the fixed point and its basic reproduction number (R_0). Performed stability analysis and numerical simulation to see population dynamics. Next, a sensitivity analysis of the parameters was carried out to see its effect on R_0. From the analysis obtained two fixed points, namely non-endemic and endemic fixed points. Non-endemic fixed points are locally asymptotically stable if R_0 <1 Meanwhile, the endemic fixed point is locally asymptotically stable if R_0 > 1. Hepatitis vaccination affects the number of susceptible population, because the more successful the vaccination, the smaller the number of susceptible populations so that the smaller the population will be infected.
