I. Introduction
The Ijen sub-district is located at an altitude of 1,000 to 1,500 meters above sea level, 8°03'30"
south latitude, 114°14'30" east longitude and has 9.58% of land for Tegal, 23.56% of plantation land for PTPN XII, 62.5% of forest area, and 3.91% of land for buildings [1]. In order to support the economic activities of the community in Ijen sub-district, a large territory with a population that keeps expanding each year needs appropriate energy delivery. The Ijen sub-district offers tourism potential from natural resources in the form of hot springs in Blawan, according to the findings of geological and geophysical studies [2]. In order to provide the best possible service, it is now essential to maintain the distribution of electricity and the collecting of consumer data. The electrical distribution line is known to be 67.65 kilometers long from the substation feeder to the trouble-prone Ijen sub-district. Distribution network disruptions are typically brought on by natural calamities, protection system failures, and striking trees with cables [3]. The producers and consumers are directly impacted by any disturbances that take place. While the disruption damages the energy distribution system on the producer's side, blackouts on the consumer's side shorten the useful life of the user's electrical equipment. This study is based on previously conducted research that was connected to many research topics [4].

Article history:
Accepted In the Ijen sub-district, care must be taken to avoid overlapping uses
of PTPN XII-owned plantations, resident fields, and the medium- voltage power distribution network. To lessen the interference factor in the distribution of electricity, the proper power distribution path must be chosen. The contact between trees and lightning is one of the variables that disturbs the distribution pathway. It is well known that the Jampit distribution substation in the Ijen district is situated in a region with plantations and private fields, making it susceptible to lightning and contact with trees. The position of distribution substations, medium-voltage overhead lines, and the location of energy users are among the issues examined in this study. In order to create a map of the electricity distribution network at Jampit distribution substations that pass through agricultural land and plantation areas, ArcGIS is used to help process spatial data including regional administration data, type of conductor, power capacity, distribution substation poles and electricity users.

II. Method
There are several stages of research on the topic of utilizing ArcGIS to map energy distribution networks at distribution substations.
Figure 1. Flowchart of electricity distribution network mapping at Jampit distribution substation The processed data includes primary and secondary data, primary data includes spatial administrative data for the Ijen sub-district and data on existing electricity distribution channels.
Meanwhile, secondary data includes GPS measurement data at distribution substations, medium- voltage overhead lines and low-voltage overhead lines.
A. Data Collection and Field Data Analysis
In order to get coordinates in the field using a GPS navigation instrument, the data was received from PT. PLN and direct measurements made in the Ijen sub-district region. The coordinates of the sites at the Jampit distribution substation are measured in order to create the GPS data collection area. Additionally, documentation related to customer information, high-voltage overhead wires, and low-voltage overhead lines is carried out.
B. Data Processing
a) RBI Map Scanning
The 1:250,000 scale Bakosurtanal map obtained was then scanned to get an image of the map in .jpg format. This procedure is carried out to produce a digital map in the .dwg format that serves as the foundation for a geographic information system.
b) Coordinate Transformation
The map obtained in the form of .jpg is then transformed to match the coordinates in the field.

c) Digitization Process
The map that has been rubber sheeted is then digitized to obtain a digital map. The digitized layers are sub-district boundaries, district boundaries, roads, rivers and settlements. The results of the digitization are in the form of a thematic map which contains the distribution of electricity customers at the Jampit distribution substation.
III. Results and Discussion
It has been determined through the mapping of the power distribution network in the Ijen District at the Jampit distribution substation that the construction of Medium-voltage Overhead Line poles in plantation areas and people's fields overlaps with other land uses. Tall species including pine, mahogany, sengon, teak, and coffee plantations make up the majority of the plant diversity in the Ijen District area. The following table lists the different types of conducting cables and installed power based on primary data collected from a number of customers:

According to Table 1, the distribution substation in Jampit has a capacity of 100kVA and a terminal voltage distribution of 211V. Table 2's information on the medium voltage network reveals the type of conductor used, which is All Aluminum Alloy Conductor Shielded (AAACS). This type of conductor has an overhead line height of 12 meters, a cable cross-sectional area of 150mm2, and a maximum current distribution capacity of 325A. At distribution substations, customer data consumes 900VA of power. The distribution channel for electricity from the main substation to the Jampit distribution substation is known in Figure 1 to pass through plantation areas and agricultural fields based on the results of mapping the network's location within the Ijen subdistrict against the area's current land cover.

IV. Conclusion
From the results of the mapping of electricity distribution channels at the distribution substation of Ijen sub-district, the following conclusions were obtained:
a. From the results of the mapping of the medium-voltage overhead line that distributes electricity from the main substation, it is known that the plantation land cover and yard land overlap with the electricity distribution line in Ijen sub-district. The topology pattern of the power grid system uses a radial system, where this pattern is widely used in rural areas. The advantages of the radial system of electricity network topology include cheap investment and simpler system control.
b. The geographic information system at the Jampit distribution substation provides information on the distribution of electricity customer locations, power consumption values and types of conductors on medium voltage electricity distribution lines. This makes it easier to plan and add new electricity networks in the Jampit distribution substation area.
