Abstract

The use of energy is important today due to the rapid decrease in fossil energy entire the world. The world should consider of using energy as efficient as possible. Waste energy from engines and other energy converters is released as hot air in the atmosphere. Waste heat energy is able to recover by using water heat exchanger. This research aims to experimentally examining the use of waste heat from room air conditioner as home energy source. A cross flow concentric pipe heat exchanger is used as the condenser for a room air conditioner to cover the exhaust energy from the condenser. The results shows that by using a concentric pipe condenser, the exhaust energy is benefit to decrease the paid energy equal to Rp. 57.000,-  monthly electricity bill. The other supplementary beneficial equal to Rp. 564.249,- electricity bill gained from exhaust energy of the air conditioner.    Keywords: : hot air, energy source

Abstract

Currently, people at Lekke Village use electricity supplied by Micro hydro Power Plant. The plant of this turbine is located at about 5-6 km from the village and operates only about 10-12 hours per day, from 06.00 PM in evening to 06.00 AM in the morning. The remote location of the micro hydro plant decreases the received voltage at the community. Besides, the unstable condition of turbine installed at Lekke Village resulted in the fluctuation of the output frequency and voltage.  At dry season, the decrement of water flow makes the decrement of the supplied power from the micro hydro plant. While in rainy season, the turbine sometimes fail to operate properly because of garbage, dry leaves, etc. which fall into the river and blocked its flow. Due to this condition, the needs of electricity at Lekke Village are crucial and needs the installation of solar power to meet the community needs. This activity trains local people to have a basic ability on how to build hybrid power installation of turbine and solar power. For this purpose Pengabdian Kepada Masyarakat (PKM) Team from Enginering Faculty of Atmajaya Makassar University is funded by Dirjen Pendidikan Tinggi, Riset dan Teknologi Kementerian Pendidikan dan Kebudayaan through Kegiatan Bantuan Pendanaan Program Penelitian Kebijakan Merdeka Belajar Kampus Merdeka dan Pengabdian Masyarakat Berbasis Hasil Penelitian dan Purwarupa PTS Ditjen Diktiristek.  This training provides 2 basic skills to local people: 1). How to install Solar Power to be used at Sound System and lighting in the St.Anna church; 2) How to build the control system for the hybridization of micro hydro power-solar power.  This training conducts in 2 consecutive session which is training session and installation session. Training session provide basic knowledge of micro hydro power-solar power to the local people and at the installation session the local people together with the trainer work together to install the solar power at St. Anna Church. This activity installs 2X140 WP solar panel with capacity equal to 140 Watt. The solar panel supported by 2x60 Watt batteries. After the installation, the installed system at St.Anna Church able to work 24 hours, supply 70 Watt Sound System and activate 10 lighting points where each point needs 7 Watt. The hybrid installation equipped with a controller that gives ability to select the input power from micro hydro power or from solar power

Abstract

The digital to analog converter module uses the binary weighted resistance method and the ladder method designed by Aries Kamolan makes it easy to convert data and see the process of changing digital data to analog data. By using this module, it is hoped that people will easily learn and be interested in this field and can distinguish digital data and analog data. The youth community who are members of the Bonggakaradeng Youth Association (HPBK) which is secretariat at BTN Risky housing, Kapasa sub-district, Tamalanrea sub-district, Makassar City,  were chosen to be partners in this service because there are still many communities who cannot distinguish digital data and analog data and the use of these data and how to convert digital data to analog. The solution overcomes this problem by providing counseling and training to them using digital to analog converter modules using the binary weighted resistance method and the ladder method. The goal is that partners can easily perform data conversion and see the process of converting digital data to analog and introduce electrical engineering in the community. This activity went well even though the number of participants was not too much, but it seemed enthusiastic for HPBK members to take part in this training. HPBK members also want to know the basics of electrical science and the various electrical components in the module. They also expect this kind of activity again.
