Judul: Nutritional Garrying Gapacity of Social Forestry In Lampung Barat District
Abstrak: The Government of Lampung Barat District issued Social Forestry Program to address forest degradation problem that caused by illegal logging. Therefore, nutritional carrying capacity of Social Forestry was important to be analyzed to understand the advantage of Social Forestry for farmer. The objectives of this research were to 1) analyze the characteristics of farmer household, 2) analyze the commodity diversity of Social Forestry, 3) analyze nutritional carrying capacity of Social Forestry, 4) analyze household food access based on income and food expenditure, and 5) analyze factors related to nutritional carrying capacity and food access of farmer household. The research was conducted by using cross sectional study design. The sample was 90 Social Forestry's farmer households chosen by using purposive sampling method. The result of the research shows that almost all samples are small family which has elementary school-education-Ievel and are Sundanese and Javanese.

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.
