Judul: Hot Pepper (Capsicum Annuum. L) Online Agribussiness Consultasion System
Abstrak: The objective of the research was to develop an online consultation system for Chili Pepper (Capsicum annuum. L) agribusiness. The method included problem identification, the search knowledge sources, knowledge acquisition, knowledge representation and online consultation system development. Knowledge from the expert and other’s materials has been captured and represented using production rules for develop the system. The system was developed using extreme programming (XP) which included the stages of analysis, design and implementation. The results of this research is on line chili pepper agribusiness consultation system consisting of consultation modules like choosing the chili pepper variety, determination of fertilizer dosage, pest and deasese handly, cultivation knolwedge, farming bussiness analysis, climate conditions, governement policies, and chili pepper price information.The prototype of the system has been implemented using PHP and MySQL and running well on the internet. User can access the system using internet browser at www.cabe.ipb.ac.id.

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.
