Abstract

The development of electric vehicles in Indonesia began in 1997 by the IndonesianInstitute of Sciences (LIPI) but since 2013 has slowed down. Presidential Regulation 55/2019strengthens the development of electric vehicles in Indonesia which followed by severalsupporting regulations. Currently, the development of electric vehicles, both in terms of researchand industry or commercial products, is getting better. This paper reviews the current status ofelectric bicycles and electric motorcycles in Indonesia which are commercially available. Theresearch was conducted by through online survey during 2020-2021 which produced adatabase of electric bicycles/motorcycles. Currently, there are 64 electric bicycles and 44electric motorcycles. These vehicles use either two or three wheels with electric drive capacitybetween 180 W to 4200 W. The most common electric motor used is BLDC at 87%. The electricbike/motorcycle has speed ranges between 20 km/h to 70 km/h with battery capacity of 5,2 Ahto 70 Ah with milage ranging from 15 km to 200 km. The information presented will helpstakeholders to get a quick overview of the development of electric bicycles/motorcycles in thecountry and serves as benchmark for developing electric bicycles or motor to meet domesticneeds.

Abstract

Solar photovoltaic is one solution to provide green and sustainable electricity. Currently, most of PV application requires inverter as the electrical appliances are mostly powered by AC voltage. The inverter is the most complex components in a solar PV system as it contains complex electronic circuitry and also expensive. One solution to eliminate the use of an inverter is DC house in which power is distributed in DC voltage. For the urban consumer, which uses a wide range of electrical appliances, DC house requires the availability of DC powered electrical appliances. However, information about the availability of DC powered equipment is still limited. This paper reviews the availability of DC powered electrical appliances to get insight into the current status of this device. This study conducted an online survey targetting popular e-commerce which sells electrical appliances. The study showed that almost all electrical equipment commonly installed in the urban house of Indonesia are now available as DC powered appliances.

Abstract

Solar Power Plant (PLTS) as one of the renewable energy sources that is being focused on itsdevelopment. This article discusses the design and simulation of the performance of a 1 kWp rooftopsolar power plant using a Helisocope. The input data required by the Helioscope is PLTS technicalspecifications such as solar panel technology, inverter type, number and type of modules selectedand land area. The location data required by the PLTS system includes the coordinates, the type ofroof of the building, the environment around the PLTS and meteorological data. The 1 kWp PLTS roofsystem designed at the location that the author uses uses 7 pcs Canadian Solar 195 Wp panels, 1pcs 1 kW AEC inverter, installed on the roof of the building facing north, and connected to the PLNnetwork via a net meter. This 1 kWp rooftop PLTS is capable of producing an average daily averageof 5,48 kWh, 41,07 kWh weekly, 164,29 kWh monthly, and annual 1971,5 kWh. Energy productionvaries by an average of 8% per month with the minimum production in January of 135,1 kWh and thehighest in July of 184,5 kWh. The designed 1 kWp PLTS roof produces a performance ratio of 73,6%with the irradiation received in a year reaching 1859,2 kWh/m2. The initial investment required to builda 1 kwp PLTS roof is IDR. 20.000.000.

Abstract

Solar Power Plant (PLTS) is a renewable energy that converts sunlight into electricity.However, the construction of PLTS requires a large area of land so that for urban areas it is noteasy to get the required land. One of solution to this problem is to use the roof of the parkingbuilding as a rooftop solar power plant, the energy produced by the rooftop solar power plantcan be exported to the network because generally the energy demand for parking buildings isnot much. This paper discusses PLTS on the roof of parking buildings that have been built allover the world. The results of a review were obtained as many as 40 PLTS on the roof of theparking building which were built from 2010 to 2022 with a total capacity of 207,49 MW. ThisPLTS parking facility was built in the form of PLTS on the roof of the parking building, carportand parking canopy. Institutions that have built PLTS above their parking facilities includeairports, banks, malls, governments, water companies, recycling companies, pharmaceuticalcompanies, financial companies, car companies, hospitals, schools, stadiums and universities.

Abstract

The Ramada Bintang and Ramada Camakila hotels have pools of nearly equal water, but these two pools have different pumping and pumping systems. Ramada Bintang uses two pumps 5 Pk works 12 hours while Ramada Camakila uses two pumps 1.5 Pk work 24 hours, the condition of both pools have the same clarity and water quality. In this study, electrical energy measurements were performed on each pump and calculated chlorine, ph and number of people taking bath in each swimming pool. The average electricity consumption per day on the Ramada Bintang hotel pumping system is Rp. 106,080 while Ramada Camakila Rp. 74,640, so the difference in electricity consumption for a year in both hotels is Rp. 10,579. 068 with the same water quality ratio.

Abstract

The cleanliness of the solar panels is one of the factors that affect the energyproduction of a solar power plant. Solar panel cleaning is a solution to keep solar panels cleanso that energy production can be optimal. This article reviews research developments andcommercial products for solar panel cleaning, with the result showing various applicabletechniques and commercial products for solar panel cleaning purposes. There are two distincttechniques used in solar panel cleaning, manual and automatic. The manual cleaning method isa method that conducts any action to operate the system manually by humans. The automaticcleaning method is a method that is controlled directly by the system without the need forhuman interference. Commercial solar panel cleaning products include telescopic polesequipped with brushes and water pumps, a robot that is permanently attached to the solar panelsupport construction equipped with dry clean and water clean methods, a robot with portablesystems using long roller brushes, a convenient robot which has a remote vacuum cleanersystem, to a mobile cleaning system using a robotic arm.

Abstract

Solar Power Generation System (PLTS) is a power generation system that utilizes sunlight as a renewable energy source and a rooftop as a place for solar panels. This paper presents the results of a study of the potential of a rooftop-based solar power plant in the city of Denpasar by taking a location on the roof of the SD Negeri 5 Pedungan Diponegoro No. 60 Denpasar road using PLTS objects that have been installed. The study was carried out with the help of Heliospoce software. Based on the study, information was obtained that the potential of solar energy was 1912.8 kWh / m2 / year or an average of 5.2 kWh / m2 / day in the city of Denpasar. Sunlight that can produce electricity starts at 07.00 -18.30 WITA. The installed energy potential of PLTS is 3214.6 kWh with an angle corresponding to the roof angle of 30.96o. The result of the potential energy produced will be greater if the installation of PV uses the optimal angle (15o) that is equal to 3407kWh.
