Abstract

A kiosk substation is a compact, prefabricated enclosure constructed from steel or fiberglass that houses a complete distribution unit, including a medium-voltage cubicle, distribution transformer, and low-voltage switchgear. Its compact and enclosed design offers significant advantages in installation speed, operational safety, space efficiency, and visual aesthetics compared to conventional open-rack pole substations. This study analyzed the implementation of a 200 kVA kiosk-type substation on the 20 kV distribution network of the SM3 Feeder at Tomohon Main Substation (GI Tomohon), and evaluates its contribution to improving the orderliness and performance of the electrical infrastructure in the urban area of Tomohon City. The methodology encompasses a comprehensive literature review, direct field observation along Jl. Kompleks Rindam Kakaskasen to Stadion Babe Palar, collection of technical data including installed transformer capacities, network lengths, and component inventories, as well as structured interviews with technical staff of PT PLN (Persero) UP3 Manado. Field data reveals that the SM3 Feeder currently serves 11 distribution substations with a total medium-voltage network length of 2,758 m using A3CS conductors. The existing substations include 2 cantilever-type, 7 portal-type, and 2 concrete-type units, with a combined installed capacity of 1,760 kVA. Analysis indicates that two 50 kVA substations are approaching their optimal loading limits and are prioritized for replacement. Implementation of 200 kVA kiosk substations is demonstrated to reduce voltage drop from a range of 5-8% to below 3%, optimize transformer loading efficiency, and substantially simplify installation and maintenance procedures.

Abstract

Inadequate lighting in rice cultivation fields at night poses significant challenges that can reduce farmer productivity, especially during planting and harvesting seasons when extended working hours are crucial. Moreover, insufficient visibility at night increases the likelihood of disturbances from nocturnal pests such as rodents and birds. At the same time, limited access to electricity in the fields hinders the ability to provide adequate lighting. This study is not intended to create off-grid lighting supported by solar panels as a sustainable and energy-efficient alternative application for the land. This research uses a literature review method and a technical analysis of the system's individual components, including solar batteries, controllers, and LED lights. The findings show that this system can theoretically provide lighting for 10-12 hours each night and can operate even in cloudy weather thanks to battery storage. This technology can enhance farmers' safety and comfort during work and can be further developed into IoT-based smart agricultural solutions.
