Abstrak: Sericulture are planting the mulberry as silkworm feed, producing the silkworm eggs and maintaining of silkworm till to fornlating the cacoon. It like a household business that relatively easy because it have a simple technology and intensive labour. The aim of this research were analyzed the characteristic of silkwomi farmer and analyzed feasibility of sericulture. The study was carried out on March 2006 at Silkworm Farmer Cooperation Sabilvlungan I11 and it was designed as a case study. It used primary and secondary data. The analysis data were descriptive and feasibility analysis. The silkwornl Iarnler were divided to three business scale according to square of mulberry garden. The characteristic of sikworm farmer were age, education level, experienced of sericulture, earning and status of land. Feasibility analysis is formulated based on two assum?tion. Follnulating of two assumption is adjusted to the real condition at research place. First, counting the cash flow without land rent and wage of fanlily's labour. This assumption showed that the sericulture is feasibled to ran with discount rate 12%. But, in second assumption that counting cash flow with land rent and wage of fmily's labour, it showed that sericulture is unfeasibled to ran with same discount rate 12%. Key Words : silkwornz, sericulturc., feasibility analysis

Abstrak: Sericulture development has a promising prospect because it support several business unit : cocoon producing, spinning and weaving The objective of this research was to analyse the level of added value from silk activity in business unit h m silkworm to cocoon, cocoon to silk yam, and the silkworm to silk cloth at KOPPUS Sabilulungan III, Tasikmalaya This research was designed as a case study research and conducted from March until April 2006. The data consisted of primary and secondary data This research used descriptive analysis and hayami method for added value analysis. The result indicated that activity in KOPPUS Sabilulungan III consisted of sericulture, spinning and weaving. Added value in each business unit wexe low : 2333% in sericulture, 25,51% in spinning unit and 39,68% in weaving unit To generate the . added value there has to be improvement in maintenance system in sericulture, optimalization of utility in spinning unit and diversification product in weaving unit Keywords : added value, silk

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
