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: Karakteristik Nilai Kuat Tumpu Baut pada Kayu Meranti Merah (Shorea spp.) dan Merbau (Intsia spp.) menurut Beberapa Diameter Baut dan Arah Pembebanan Serat Kayu
Abstrak: Kekuatan tumpu baut merupakan salah satu faktor yang mempengaruhi kekuatan sambungan kayu dalam menahan beban pada konstruksi bangunan struktural. Penelitian ini bertujuan untuk mengetahui nilai kekuatan tumpu baut menggunakan tiga ukuran diameter baut dengan arah pembebanan serat kayu pada jenis kayu (meranti merah dan merbau). Pengujian yang dilakukan terdiri atas sifat fisis, sifat mekanis, dan kuat tumpu baut dengan bentuk ukuran telah dimodifikasi yang mengacu pada standar BS-373 (1957) dan ASTM D 5764-97a (Reapproved 2002). Hasil penelitian menunjukan bahwa kayu merbau memiliki nilai kuat tekan sejajar dan tegak lurus serat serta kuat tumpu baut lebih besar dibandingkan kayu meranti merah. Faktor yang mempengaruhi kuat tumpu baut adalah jenis kayu, diameter baut, dan arah pembebanan. Ukuran diameter baut memberikan pengaruh yang nyata terhadap kuat tumpu baut dimana terdapat kecenderungan diameter baut yang semakin besar akan mengakibatkan nilai kekuatan tumpu baut semakin menurun.
