Judul: Online chili (Capsicum annuum. L) agribusiness consultation based on mobile system
Abstrak: A mobile based Chili online agribusiness consultation system is a consultation system which serves the information and knowledge for farmers and stake holder involved in chili Agribusiness so they can access all needed information in processing, marketing, and developing their agricultural products by using mobile device such as: hand phone, PDA that have GPRS (General Packet Radio Services). The purpose of the research is to make the farmers as direct independent users in getting the information, by using information technology, so the mobile device it can be communication media and knowledge based consultation devices. The developing of mobile based consultation system is for supporting the activities of Agribusiness that include market information, weather information, and government policy about the farm production result that will be observed to give solution for Agribusiness doers, especially for the chili farmers in consulting all information needed to develop the result of Agriculture. This system is built by using System Development Life Cycle (SDLC) approach. It is an adaptive extreme Programming which is one of Agile’s methodologies that consist of explorating, planning, iteration launching software. The source of knowledge is gotten from the experts, police makers, customer, research institution, University, and from books, research journals, bulletin, and online information system.

Judul: Pengembangan Sistem Pakar Agribisnis Cabai (Capsicum annuum. L) Berbasis Android
Abstrak: The objective of the research was to develop a consultation system for Chili Pepper (Capsicum annuum. L) agribusiness based on android. The method included problem identification, the search knowledge sources, knowledge acquisition, knowledge representation and consultation system development based on android. Knowledge from the expert and other’s materials has been captured and represented to develop the system. The system development was done by using extreme programming (XP) which included the stages of analysis, design and implementation. The results of this research is a chili pepper agribusiness expert system based on android which consists of nine consultation modules like choosing the best cultivar, fertilizing recommendation, land preparation, identified disease, controlling insect pest, farmers income and profit gain, after harvest’s technique, government policy, and price information based on user’s location. The system was running well on the android phone. Users can download the application from http://apps.cs.ipb.ac.id or http://appsriset.ipb.ac.id as a mirror link, then install it on their smartphone or computer tablet .

Judul: Penggunaan Teorema Homeomorphy 2-Manifold dan Teorema Euler Poincare pada Torus 𝑇�� dan Simplicial Complex 𝐾��
Abstrak: Two dimensional topological spaces are said to be homeomorphic if they have the same topological invariant, where one of topological invariant used is an Euler characteristic. Homeomorphy 2-Manifold’s Theorem and Euler Poincare’s Theorem are used to distinguish two topological spaces. Homeomorphy 2-Manifold’s Theorem uses Euler characteristic to identify two dimensional topological spaces. Euler Poincare’s Theorem is an alternative way to find Euler characteristic with Betti number, which is topological invariant as well. The objective of this paper is to investigate the homeomorphism of torus 𝑇����� and simplicial complex 𝐾�����. Topological space torus and simplicial complex 𝐾����� have the same Euler characteristic, which is two. Based on Homeomorphy 2-Manifold’s Theorem topological space torus 𝑇����� and simplicial complex 𝐾����� is homeomorphic.
