Implementation of Appropriate Technology Polycrystalline Photovoltaic as New Renewable Alternative Energy in Public Street Lighting (PJU) at Pakuniran Probolinggo Area

Public road lighting (PJU) in the Pakuniran area, Probolinggo, East Java, more precisely in Gondosuli Village, is not sufficient. An environment without street lighting will be like a dead zone and can occur in many cases of crime, and traffic accidents and will hurt social life at night. Therefore, the community service team at the State University of Malang (UM) through student service provided a solution to reaching the road by utilizing new, renewable energy from polycrystalline solar panels to turn on the lights at night. The results of observations and site surveys show that several points require PJU installation with polycrystalline technology. The implementation carried out in Gondosuli Village was carried out in several stages, namely: observation, preparation of PJU designs, training and maintenance, performance testing, and evaluation tools. This activity, which was completed within 2 months, resulted in 5 PJUs being placed at several points with minimal lighting conditions and received a positive response from the community.


INTRODUCTION
Street lighting is designed to make life easier and help people see objects on the street at night or in dark environments.An environment without street lighting will become like a dead zone and can result in many cases of crime (Ullah & Oktaviandra, 2020), traffic accidents (Nadhiroh, Aji, Kusnadi, & Dwiyaniti, 2022) and will hurt social life at night (Hutajulu dkk., 2022).An area with good public lighting will be a better and more beautiful face of the environment.It also has a better impact on public social life.One of the regional infrastructure developments is the construction and installation of public lighting (Ferza & Pranasari, 2020).The implementation of public street lighting construction requires good planning, as well as the installation of street light lighting which has high performance and strong power, is quite light, and has low operating costs (Sukma, Azis, & Pebrianti, 2021).Gondosuli Village is a village located in Pakuniran District, Probolinggo Regency, East Java Province, Indonesia.This village is in the highlands and has an area of around 542.67 hectares (Sya'roni, Mulyati, & Hidayat, 2021).Gondosuli Village borders Batu Gajah Village to the north, Pakis Village to the east, Ranon Village to the south, and Bima Village to the west (Sari, 2021).Gondosuli village is a strategic location to connect villages.To improve the economy and strengthen the tourism industry, the Gondosuli village government has developed several development programs, including building PJUs, developing tourist villages, and building supporting infrastructure such as roads and bridges (Abdillah, Afandi, Falah, & Firmansah, 2020;Abdillah dkk., 2022;Habibi dkk., 2022).
Village Public street lighting is one the important things because it is related to the safety and security of road users, especially at night which requires good lighting (Faiz dkk., 2023;Hartono, Prabowo, Sudarmaji, & Hariyadi, 2021;Pulungan, Hamdani, Yuhendra, & Islami, 2021).Lack of lighting on the road can have dangerous impacts on society, one of which is increasing the risk of road accidents and increasing the crime rate on the road (Lutfiah & Suyandi, 2021;Novendra, 2021).Therefore, Mr. Muhammad as the head of Gondosuli village conveyed the importance of PJU, among other things : 1. Security: PJU is very important to improve security in Gondosuli Village.With PJUs, vehicle drivers and pedestrians will more easily see the road, obstacles, and other potential dangers at night.This will help reduce the risk of accidents and criminal acts in the area (Manggalou, Nafi'ah, & Uang, 2023).2. Accessibility: PJU will also improve accessibility in Gondosuli Village.With lights on the main roads and public areas, village residents will feel more comfortable doing activities outside the house at night because Gondosuli is a strategic area that connects several areas in the district, Pakuniran.This will facilitate local economic activities and strengthen social and cultural life in the region.3. Tourism: Gondosuli Village has great tourism potential, especially in the fields of natural and cultural tourism.With PJU, tourist attractions in the area can remain open longer at night, thereby increasing people's income and welfare and attracting more tourists to visit.4. Development: PJU will also support development in Gondosuli Village.Having lights on main roads and public areas will facilitate access to public infrastructure and services such as schools, clinics, and shopping centers.This will accelerate economic growth in the region.In this context, PJU is very important to be able to carry out activities in the area at night, so that it will strengthen the tourism industry (Lestariningsih, Triono, Hidayatullah, & Wicaksono, 2023), security, accessibility and improve community welfare where there is minimal street (Handoko & Handayani, 2023) lighting in Gondosuli.Therefore, partners convey problems related to PJU construction as one of the important needs of the region.
Figure 2. Pakuniran area of Gondosuli Village Figure 2 is a road in the Pakuniran area, precisely in Gondosuli village, which still lacks public street lighting (PJU).Based on the results of interviews conducted with partners, several problems were found, including the need for public street lighting (PJU) (Rosalina dkk., 2023), the need for environmentally friendly equipment by implementing an environmentally friendly PLTS independent electricity source (Baskoro, Handoko, Agung, Widyartono, & Kartini, 2021;Falah, Syah, dkk., 2023), then the need for training in the use, maintenance, and repair of the technology offered (Falah, Handoko, Syah, Azizah, & Gumilar, 2023).
After seeing and considering the problems faced by partners, the service team has a solution, namely a technology or Public Street Lighting (PJU) system to provide a sense of security and comfort when carrying out activities in the area at night, so that it will strengthen the tourism industry and improve community welfare.and can improve security, facilitate the economy, encourage tourism, and reduce crime rates.Public Street Lighting (PJU) is assisted by Polycrystalline Photovoltaic PLTS to make it more environmentally friendly (Harahap, Adam, & Oktrialdi, 2022;Pawitra, Kumara, & Ariastina, 2020;Windarta, Sinuraya, Abidin, Setyawan, & Kusuma, 2019).The hope is that the PJU PLTS Polycrystalline Photovoltaic will be able to improve the quality of lighting in several Pakuniran areas in Gondosuli Village.
