The Local Government has undertaken various steps in its development but the production, however, does not meet the market demand since the farmers have no incentives to increase production. The unproportional income received by farmers compared to those earned by Aloe vera entrepreneurs could also be the cause of farmers not to increase production. Aloe vera flour industry which is expected to increase farmers interest to boost Aloe vera production faces marketing constraints. Both agribusiness development strategy and Aloe vera flour industrial development are needed to encourage farmers to increase production. Based on the above problems, this study aims at: (1) Predicting the demand outlook of Aloe vera, (2) Identifying Aloe vera market chain that benefits farmers, (3) Determining financial feasibility of Aloe vera flour industry, (4) Developing Aloe vera agribusiness development strategy. This research was conducted in Pontianak using both primary and secondary data.

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.
