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.

Protected forest areas have the main function of protecting life support systems. The protected forest area of ??Ekasari Jembrana Bali has an area of ??1.603 hectares. In the Ekasari protected forest there are many illegal logging actions. In 2020 there were two cases of wood theft. The types of wood stolen were reed and rosewood. In addition to these two cases, in 2018 to 2019 there were more than 10 cases of illegal logging that occurred, it is necessary to have a tool that is able to detect the occurrence of illegal logging in protected forests. The working system of this tool uses a Pi NoIR camera module to take pictures and a sound sensor FC-04 to detect the sound of a chainsaw with a value of 55 dB. This tool uses a Raspberry Pi microcontroller which functions to receive and process data, so that it is able to display warnings on websites and telegram applications. This tool has a detection range of 1,1304 hectares, so 1.418 tools are needed in the entire protected forest area of ??Ekasari Jembrana Bali.

Technological advances have been utilized in various fields, including in agriculture.The technology that is currently widely used is the Internet of Things (IoT). With this technology,farmers can monitor and control remotely so that their work becomes more efficient and optimal.In this study, a control and monitor system was developed for paprika hydroponics. This systemwas built using a Rasberry Pi as a data processing center equipped with Arduino uno as ananalog data reader and relay control, a DS18B20 sensor as a water temperature reader, a pH4502C sensor as a water acidity reader, and a TDS/EC sensor as a water nutrient ppm valuereader. This system is realized in the form of a prototype system for hydroponic paprika. Thesystem works automatically to monitor and control water temperature, water pH, nutrient ppmvalue, water level and automatic watering. The system is also equipped with a notificationfeature so that farmers can obtain information via telegram media such as water temperature,water pH, nutrient ppm value, water level, and watering notifications. This prototype is alsoequipped with a webcam camera as a feature that functions to detect ripe peppers in terms offruit color. The camera will detect the color of the peppers, and if the peppers are red, thepeppers are categorized as ripe, and farmers will receive notifications via telegram in the formof image data and notifications that ripe peppers have been detected.

The single phase to ground fault on the 150 kV transmission line GIS Pesanggaran –Nusa Dua Substation has a high fault impedance so that the distance relay as anauxiliary safety device cannot detect the disturbance. Directional Ground Relay (DGR)was chosen as an auxiliary protection relay to secure the system from single phase toground faults. Installation of auxiliary protection relays requires planning and relaysetting steps to obtain Iset, TMS and trip time. The calculations that have been carriedout get the results of DGR setting with a pickup current range of 0.0522 – 0.0722 A.DGR will work after 2.297 seconds if the differential relay as the main protection relaydoes not work or fails and the distance relay as a backup protection does not succeed insecuring a single phase fault to ground as well.

The increasing need for electrical energy every year results in the availability of energysources is dwindling. Therefore, the need for energy conservation to streamline the use ofelectrical energy without reducing its comfort or productivity. The main factor of energyconservation is energy auditing. Plasa Telkom Teuku Umar is a company engaged intelecommunications. The convenience of employees and customers takes precedence overthis0company.0The best service0must also be followed by the efficient use of facilities. For thisreason, an electrical energy audit is needed. In this study, it was attached0to theair0conditioning0system and lighting system. It is attached to the air conditioning system andlighting system. Tools0that can be0used for measurement in the field are Lux Meter, (lightintensity measurement), Tang Ampere (electric current measurement), and Thermometer (roomtemperature measurement). The study was conducted by0calculating and comparing0electricalenergy consumption in lighting and air conditioning systems between before and after anenergy audit. Calculate the pre- and post-audit IKE (Energy Consumption Intensity) andcompare it to the IKE standard. The results of the study found energy savings of 36.06%. Fromelectricity usage of 16.86 kWh/m2/bln pre audit to 10.78 kWh/m2/mo post audit.

The rooftop on-grid PLTS system is commonly used by people from the household,commercial, to industrial sectors to reduce electricity bills from PLN. Based on PERMEN ESDM49 of 2018, the export value of electrical energy to the PLN electricity grid is 65%, and if energyexports are greater than energy bills, the rest will be stored and accumulated in the followingmonth. This is only valid for a maximum of 3 months, in the 4th month the remaining energyexport savings will be eliminated. Determining the right PLTS capacity makes the contribution ofPLTS in making bill savings more optimal. The office of BAPPEDA LITBANG Probolinggo Citywas used as the research location. The PLTS Scenario 1 design uses a capacity according tothe energy needs of the office, which is 21.6 kWp, and the PLTS Scenario 2 capacity is greaterthan the office energy requirement of 32.4 kWp. Based on the investment feasibility analysisusing the NPV, PI, and DPP methods, it shows that the Scenario 1 and Scenario 2 PLTSdesigns are feasible to run. PLTS Scenario 1 and Scenario 2 investment is Rp. 267,000,000and Rp. 395.85 million, respectively. The benefit of saving bills for 30 years of PLTS operation,in Scenario 1 is Rp. 406,863,069 or 152% of the total investment, while Scenario 2 is Rp.595,619,904 or 150% of the total investment.

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
