This weakness is very influential on the performance and the success rate of the union’s agribusiness and the success rate of the program itself. Given these problems, it is necessary to create an information system and decision-making that can be used by the union or its extension companion in its business operations.

Yogyakarta, whereas experts for the AHP questionnaire consisted of the Director of Finance Directorate of Directorate General of Agricultural Infrastructure, Head of Yogyakarta Assessment Institute for Agricultural Technology, and Head of Sub Directorate Agribusiness Finance of Finance Directorate of Directorate General of Agricultural Infrastructure Ministry of Agriculture. Meanwhile the system specification detail developed in Bogor and Jakarta from November 2012 through June 2013. The study stages starting from requirement analysis, problem formulation, system identification, and so on until the users evaluation. The aspects of concern in this study consists of database management system (DBMS), model base management system (MBMS), and the dialogue system. The DBMB regarding the adequacy of PUAP data stored in the system, the MBMS regarding the suitability of the model to the union’s needs (eligibility criteria, as well as the format and type of report), while the dialogue system regarding ease of use of the system by the union. Information Systems and Decision Making for Gapoktan Pengembangan Usaha Agribisnis Perdesaan (PUAP) named as SIPK-GP 1.13 is the information system for performance management of the union and decision support in selecting the business focus of farmers’ group members. The user interface as the major part of SIPK-GP 1.13 which serves as medium of communication between the users with the model. The SIPK-GP 1.13 is a package of windows based information systems and decision-making with Indonesian as the default language. This makes the operation of SIPK-GP 1.13 becomes easy. Media interaction with the system is done by using a keyboard and mouse. The system can be operated on a computer with at least has a Pentium 4 processor, 1 GB of RAM, and

The objectives of this research were: (1) to describe the performance communication of Gapoktan, (2) to describe the characteristic, role and ability of Gapoktan, (3) to analysis the correlation between all variables. This research resulted several important usults, namely: The communication of Gapoktan was good and the communication change agents were not enough until less than not enough.

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.
