Abstract

Seng Bumiayu Market is a building that is still under construction, use and installation of electricity in the market building must be considered from the planning according to the Indonesian National Standard (SNI) and the General Electrical Installation Requirements (PUIL). the availability of electricity can be fulfilled optimally and the installation has been installed capable of supporting the operation of equipment that complies with standards so that security and safety can be guaranteed. The settlement method used to facilitate planning is collecting data, calculating and determining the characteristics of the building plan, determining load requirements, drawing a single line diagram, estimating the budget. The results of the calculation of the total load for lighting, exhaust fans and contact boxes are 13,327 watts, the selection of conductors and protection for lighting uses the NYM 2 x 2.5 mm2 type and the socket uses the NYM 3 x 2.5 mm2 type with MCB protection, the SDP panel uses type NYY 4 x 10 mm2 with MCCB safety and the voltage drop from the SDP panel to the load panel is 2.9 volts. Increasing the reliability and convenience of the installation system in the Seng Bumiayu Market building requires a generator set with a minimum power capacity of 15 kVA and calculating the budget for obtaining Rp. 600,000,000.-. The results of calculating load requirements, selection of conductors, safety requirements, voltage drop values ​​are in accordance with PUIL and SNI.

Abstract

One way to reduce carbon dioxide emissions from power plants powered by fossil fuels is by utilizing new renewable energy sources to generate the electrical energy needed each day. The Faculty of Engineering 03 UNTIDAR Building has a roof area of 997.4 m2 and a solar irradiation potential of 4.89 kWh/m2 per day, so it is very probable to build a rooftop PLTS to supply the building's lighting demand. Therefore, a plan for installing a rooftop PLTS system was implemented in this study in order to contribute to the utilization of new, renewable energy and the reduction of carbon dioxide emissions. The method employed in this planning is descriptive analysis, which includes analyses of the locations for installing solar modules, the building's daily electricity usage, the technical design of the rooftop PLTS system, analyses of the energy produced, and analyses of the potential to lower carbon dioxide emissions. According to the planning results, the rooftop PLTS has a capacity of 124 kWp and can generate 135,299,299.29 kWh of electrical energy annually utilizing 231 units of 540 W solar modules that are divided into 10 strings. 8,267.97 kWh are typically exported each month to PT. PLN as electrical energy. While the potential reduction in carbon dioxide emissions is calculated to be 135,299.29 tons of CO2 annually.

Abstract

Utilization of elevation angles and azimuth angles is a very important part in maximizing solar energy into electrical energy in photovoltaic (PV). One way to maximize PV power output is to design a single axis tracker system and take into account the azimuth and elevation angles of the sun using the sun position calculator application. The single axis tracker system is set based on the position of the angle of inclination of the surface of the PV 45°, then the angle of 90° and the angle of inclination of 135°. The test results show that the single axis tracker PV system design can work based on the angle settings that have been programmed. Then the use of a battery control system to support the PV reliability system automatically cuts off electricity when the battery voltage drops below 12 V during cloudy weather conditions and excessive battery usage. The integration of the PZEM-017 module with the battery will support monitoring of battery power usage in real time. PV energy data conversion performance uses single axis tracker technology for maximum power reaching 631.72 Watt DC at 12.00 pm and the lowest power reaching 56.02 Watt DC at 6.00 pm.
