I Gusti Ngurah Ady Kusuma

In Bali’s regency called Tabanan, nowadays there are emerging home industries producing the Kerupuk Ladrang. Kerupuk Ladrang is crispy chips made of wheat flour with some eggs and spices. For our project, we have chosen two home industries as our partner industries. The first one is the “Biang Bagus” home industry which is owned and managed by Mrs. Gusti Ayu Putu Sukarini and the second one is the “Bu Gusti” home industry which is owned and managed by Ni Gusti Ayu Komang Niri. This project, namely Program Kemitraan Masyarakat, aims in improving the production process by solving the problems that are faced by the two partners. The given solutions are by providing the better production tools and equipment, facilitating the two partners with modern marketing skills (eg. for marketing in the social medias) with some training programs, as well as providing them an Android based software application to be used as a tool in purchase-order process. In short, there are four main things done for the partners: providing them with new and better tools and equipment, services, training and guidance. The results shown the two partners have improved their production process which is now become more efficient and faster. Both of the partners are now having broader views, especially in using the modern technologies, which in this case the social medias and the Android based application software. The project is hoped to be continued so that the revenue of the two partners is increased.

Towards an immunity-based approach for preserving energy of data-gathering processes in wireless sensor network environments

Wireless sensor networks (WSN) consists of large number of sensor nodes with limited energy and computing resources. These facts have highlighted open problem to prolong the lifetime of sensor nodes while still maintaining the functional roles of WSN in reporting important events to a base station. These papers propose an approach for WSN inspired by the concept of immunity-based system where a set of reactions is performed in the appearance of nonself substances called syndromes. The notion of reactive cluster is introduced where only sensor nodes affected by the syndrome appearances need to perform reactions by establishing clusters among them. Since communication costs significant energy, each sensor nodes as an immune cell need to reduce impacts of the syndromes for itself and other sensor nodes in the routing paths to the sink node. It is done establishing adaptive data aggregation strategies. Depend on the critical level of the corresponding syndrome and error of wireless communications that may occur, the length of the aggregation window is adjusted. We show that the proposed approach shows promising results in minimizing dead sensor nodes, avoiding network congestion while still maintaining the functional roles of WSN in reporting important events to the sink node.
