Abstract

In order to investigate the behavior of the solar home systems, 10 data loggers have been installed in three different villages in Kolaka district in Southeast Sulawesi in March 2001. The solar home systems installed in Kolaka consists of a 50 Wp Solarex MSX 50 modules, 70 Ah battery, 10A/12volt battery charge regulator (BCR) and three 6W fluorescent lights. This paper will present and elaborate the performance of solar home systems, which includes Vbattery, VLoad, ILoad, Imodule and comparison between theoretical calculation and field measurement. Results of monitoring nine solar home systems in Kolaka district in Indonesia are presented. Data logger information shows typical load patterns, and differences between users. The information allows for break-down of a number of different energy loss categories. Some of these losses can be reduced by the user.

Abstract

Renewable energy sources make a distinction as a promising solution towardssustainable and environmentally friendly energy production. Developing biodiesel isvery important for Indonesia due to various reasons including the abundanceavailability of the raw materials; an alternative renewable fuel to strengthen thecountry energy security and it is a solution to improve local air quality in severalIndonesian major cities. Biodiesel offers a realistic short-term alternative tosubstitute fossil fuels, and it will also be a necessary addition to the emissionfree technology for the future. This paper is intended to provide assessment andinvestigation of the use of different composition of biodiesel and its impact to theenvironment.Key words: Energy security, renewable energy, Biodiesel.

Abstract

Indonesia through government programmes and private sector activities. An assessment on performance of photovoltaic systems and study of their impacts was established in Kolaka, South-east Sulawesi. At the moment there are 2270 solar home systems (SHS) in this location. During the research and study, there are 9 data loggers have been installed in nine solar home systems in 4 villages of Kolaka. These data loggers were used to monitor and measure some parameters such as solar insolation , VBattery,VLoad, ILoad, IModule, and room temperature. Besides performance data collection above, a quantitative research method was done to explore the quality of life of rural and remotepeoples. 175 questionnaires were used to collect the data from households in 4 villages Polinggona, Popalia, Petudua dan Pewisoa Jaya. This paper will discuss resuts of the measurement of solar home systems, the impact on daily life of villagers and global and local environmental impact of the use of solar home systems.Kata Kunci: PLTS, data-logger, alat pengontrol baterai

Abstract

Railway crossing gates are one of the railway infrastructure facilities. Currently, there are still many problems, especially in traffic accidents. The cause of traffic accidents at railway crossings generally occurs due to the lack of facilities and infrastructure (rail crossing gates) and negligence of guards in carrying out their duties. Therefore, it is necessary to design an automatic railway crossing gate. The prototype of the automatic railway crossing controller uses proximity and infrared sensors to detect the arrival and departure of trains. When the infrared or proximity sensor detects the arrival of a train, the Programmable Logic Controller (PLC) activates Pulse Width Modulation (PWM), buzzer, and Light Emitting Diode (LED), so that the crossing motor goes down. After the crossing touches the limit switch, the motor stops and the buzzer and Light Emitting Diode (LED) remain on. The infrared or proximity sensor detects the departure of the train so that it reverses the motor so that the crossing goes up, then turns off the buzzer and Light Emitting Diode (LED). In this way, it is hoped that this design can be used to increase the efficiency of the system's operational costs and optimize the railway crossing system and is expected to reduce the number of traffic accidents at railway crossings.
