Abstract

Electrical security system is the human effort to maintain security and comfort in their environment in which he works. Not least in the laboratory instrumentation and electrical Agricultural Mechanization Polytechnic State of Lampung. As anticipate things that are not desirable in respect of negligence that often occur in the laboratory such as; AC (Air Conditioning), solder, lights and other equipment that is still alive when it is not used anymore, then used as a reference for making an electrical security system as anticipation  Health, Safety, Work in the laboratory. The purpose of this tool is to make the security system of electricity in the laboratory of agricultural mechanization and the anticipation of Health, Safety, Work and to minimize damage to equipment as well as conserve electrical power used in addition to the manufacture of the tool also has a specific purpose; - By creating this system also can be used as a modeling tool or practicum for students primarily in Agricultural Engineering study program. - In order for students able to apply to the world of work, and apply to the community - Conducting development tools, according to the results of analysis of technical specifications as a means of research and community service for lecturers and laboratory assistant (PLP) Thus negligence or omission that could cause a short circuit in the electrical network, equipment breakdowns that led to a fire in a laboratory can be reduced or minimized, and it can save power consumption when the excessive electrical equipment is not used. Keywords: electrical security system, electrical power

Abstract

The vulcanization process is a chemical reaction between rubber and sulfur to form cross-links and produce a three-dimensional structure. Temperature control in the vulcanization process is important to support the quality of the goods produced. In the coconut coir rubber production unit laboratory, the vulcanization oven is still conventional and manual for temperature control, therefore an operator is required to be on standby when the vulcanization oven is operated. The negligence of the operator will be fatal both in terms of the quality of the rubberised coir produced and the risk of fire. One of the causes of frequent fires in vulcanization ovens is the difficulty in setting the temperature in the oven process. To anticipate the occurrence of fires in the vulcanization oven, it is necessary to modify and add a temperature control to the oven. Based on the above problems, modifications need to be made which include the addition of a temperature control system and fire protection that combines temperature control, electric motor, fan, and indicator sirens in rubberized coconut fiber ovens so that the quality of the products produced remains good and avoids fire hazards. With this system, it is hoped that it can provide a sense of security and comfort for operators and contribute to the world of education, especially for students of the Agricultural Mechanization Study Program and other study programs at Lampung State Polytechnic.
