Abstract

Kampung Nambangan Perak is located in Kelurahan Kedung Cowek, Bulak District, Surabaya, East Java. The majority of Nambangan residents work as fishermen. The Nambangan community is still unfamiliar with the use of alternative energy such as solar cells to replace fuel oil. The road access of village environment was only illuminated independently by installed map of people’s residents. The dim road conditions can cause a sense of alertness to residents and road users who spent the night. In addition, the installation of lamps with greater power can burden the economy of residents due to rising electricity prices. Based on field observations and direct interviews with local residents, there were three focuses aspects of this community service program, namely the introduction of alternative energy to residents, installation and guidance of lamp maintenance equipped with solar panels. Along with the implementation of guidance and education program for the Nambangan community, it is hoped that the residents will understand and feel familiar with the availability of alternative energy. The residents are also expected to be able to apply the use of alternative energy in their daily life. In addition, residents are expected to be able to carry out the process of assembling and maintaining alternative energy sources, especially solar panels.

Abstract

The Shredded fish is produced by machines automatically, which can facilitate the production process. Previously the process was done conventionally in one production run. This problem prompted researchers to create a machine by combining three tool systems to become a shredded fish processing machine, including a system for separating meat and fish bones, a cooking furnace system, and a shredded dryer/spinner system that can be controlled electrically in the production process, in addition to the shredded produced more cleanly and efficiently in one production process. This machine utilizes the power of an electric motor of ¾ Hp, which is the driving force for the meat separator machine with a rotation speed of 2840 rpm and a production capacity of 30 Kg/hour.
