Abstract

Electric vehicle is the one of important solution to reduce pollution result from fuel vehicle gas emission. By means of electrical motor the electric vehicle have  the power that convert from electrical energy to mechanical energy to turn its wheels.Many fields in electrical engineering support the electric vehicle development including electrical motor technology, power converter, digital processor based control system, and also battery technology for saving the electric energy.  Now the limited fosil based energy, the demanding of environment friendly of electric vehicle, and also technology support could motivate almost of  the auto mobile producers to give the attention  in electrical vehicle. This paper will try to explain the historical development of electric vehicle until now with the various of electric vehicles that have been produced  for instance hybrid, plug-in hybrid, and null emission electric vehicle will be presented.Keywords: electric vehicle development, hybrid electric vehicle, plug-in hybrid electric vehicle, null emission  electric vehicle

Abstract

The objective of this studywas to obtain atechnical and economic analysis of solar-powered lighting (SPL) implementation at Bali above Seawater Toll-Road. The SPL was designed to operate 12Hours/day with average illumination ≥15-lux. Those requirements can be met byan SPL unit that consists of 2-pieces 87-W LED lights mounted on 10-m double arms pole with 2.37-m arm length and 15º tilt angle. Each LED light was powered by a 260-Wp solar panel, 24V-180AH battery and 10-A solar charge controller. Every SPL unit should be installed on the toll-road median with 22.5-m pole-spacing and required 361-units to illuminate throughout 8,122.5-m toll-road length. Benefits of SPL implementation wereelectricity saving 256.15MWh/yr and carbon emission reduction 217.98TonesCO2/yr. However, the SPL electrical-based costwas 3.9 times more expensive than conventionalstreet lighting. And based onthe investment feasibility analysis using NPI and PI techniques showed that the SPL implementation was not feasible.

Abstract

PT. Indonesia Power unit Pesanggaran is one of the power generation companies in Bali, which has also participated in the development of renewable energy by installing solar PV with a capacity of 24 KW. In this research, reviews was conducted to know the condition of the solar PV plant. Review is carried out by conducting observation in the field, reviewing technical data of solar PV components, and also interviews with the staff who operate and maintain the solar PV. Through reviews it was found that the design and installation of solar PV plant is good and follows good practice of solar PV installation for optimum energy production. Due to plant location at GPS coordinate of -8,72, 115,21 therefore the solar module has been installed facing north or azimuth 0o. This module is placed on the roof of Building A, thereby reducing the cost to construct mechanical supports. The solar module was installed with a slope angle of 22o approaching the optimum slope angle. The components of the PV plant are good as they bear international standards. The solar module is CHN240-60P polycrystalline silicon with 60 cells that caccries CE certificate (Conformité Europeenne). Also, the inverter is three units of ABB PVS300-TL-800W-2 with AC output of 8,000 W which are also carries CE certificate and others. The quality of technical specifications of solar PV components and also installation of the plant has direct influence on the energy production of the plant and these have been properly implemented on the 24 KW Indonesia Power solar PV plant.

Abstract

Solar Power Plant (PLTS) is a technology to convert solar energy into electricity. RUEN statesthat the potential for solar electricity in Indonesia is estimated at 207.89 GW and it has beendetermined that the national PLTS capacity target in 2025 is 6.5 GW and continues to increaseto 45 GW in 2050. One of the efforts that can be made to achieve this target is to usegovernment buildings as a place to install PLTS. This study was conducted to find out howmuch potential electrical energy is generated on the rooftop PLTS of the North TapanuliRegent's office which has a roof slope of 52.70. It was found that the PLTS of the NorthTapanuli Regent's office has the potential to generate 39.6 kWp of electrical power. Thesimulation shows the energy data produced by the PV system is 45,646 kWh in one year andhas a role in supplying electrical energy up to 52.9%. So the total of the PV system with Gridelectrical energy supplied to the load is 86,233 kWh/year.

Abstract

The development of electric vehicles in Indonesia started after the issuance ofPresidential Decree 55/2019 about battery-based eletric vehicles. The development of electricvehicles must be supported with the charging infrastructure so users do not experienceproblems in charging the vehicles and therefore more people will switch to electric vehicle. Thispaper discusses the current status of charging infrastructure for electric vehicle in Indonesia.Currently, there are several type of vehicle charging facilites consist of 7.000 public electriccharging station or SPLU, 97 public electric vehicle charging station or SPKLU, 9 public electricvehicle battery exchange station or SPBKLU distributed across Sumatra, Java, Bali, NTB,Sulawsi and Kalimantan. In the case of Bali, there are 166 of SPLU, 5 of SPKLU, and there isno SPBKLU yet. The total accumulative energy consumed through the charging stations in Baliis 169.481 kWh. The figure is low due to lack of information about the charging station and thefact that the number of electric vehicles in Bali is still low.

Abstract

In the RUPTL PT PLN Years 2017 untill 2026, the goverment aim to reach 5000 MW of PV plant potential in 2025. But, until November 2016, the number of PV plant in Indonesia is around 11 MW. To reach the 5000 MW target, many approach must be use. One of the approach is install PV plant on goverment buildings. Pusat Pemerintahan Kabupaten Badung (Puspem Badung) is a goverment buildings complex which located in Badung Regency, Bali is one of the goverment building that can be use for this approach. This paper aim to know the potency of electrical power dan electrical energy produced by Puspem Badung if the PV plant installed on the north, east, west, and south side of the roof. Electrical energy produced by PV plant is simulated by using System Advisor Model (SAM). From the simulation results, north side of the roof can produce energy of 1.847.361 kWh/year. From the analysis, the total energy that can be produced by PV plant is 6.169.092 kWh/year. This amount can supply Puspem Badung energy need by 124,72 %.

Abstract

Solar power plants in their application have reached the aviation business. There arealready many airports everywhere that use solar power plants as their electrical energy supply.Airports and airfields have a very high opportunity to accommodate solar technology because ofopen land space. The purpose of this research is to review the advantages or disadvantages ofairports solar power plants and conduct a survey of any airports in the world that already havesolar power plants. This research used data collected from journals, articles, and news on theinternet. Those data include airports that use solar power plants, solar power plantsestablishment year, airport category, airport location, airport solar power plants capacity, solarpower plants type. Hence, the review describes the advantages and disadvantages of PLTSand its specific site everywhere. The results show that 192 airports already use PLTS as anelectrical energy supplier. The Asian continent has 43 airports, and there are 5 airports solarpower plants in Indonesia. Most of the solar power plant uses an on-grid system

Abstract

Green building is an alternative to anticipate damage to the earth due to development activities. This studyreviews the development of green building inkIndonesia with a systematic literature method. The reviewthat was carried out included regulations, implementation and implementation of green building inIndonesia. The development of government regulations on green buildings requires that every buildingmeet the criteria of a green building. There are 20 buildings that have been certified green building by 2018with the gold to platinum category. Research in the field of green building has also developed with 53scientific publications. From the latest reviews, it is found that the implementation of green building inIndonesia has been carried out in various aspects of the building. In the future, policies and regulations atthe national and regional levels are integrated with each other to implement green buildingcomprehensively in Indonesia.
