Application of Prim Algorithm to Optimize PT Inalum Housing Electricity Network: Case Study in Block-P

Introduction

The efficient management of electricity networks is crucial for ensuring reliable and cost-effective power supply to residential areas. In this context, the application of advanced algorithms and techniques can play a significant role in optimizing the design and configuration of electricity networks. This thesis aims to explore the application of the Prim algorithm in optimizing the PT Inalum housing electricity network in Block-P, Grinding Regency. The study focuses on analyzing the potential of the Prim algorithm in reducing the length of electric cables needed to connect all houses in the block, thereby minimizing material and labor costs.

Why Prim Algorithm?

The Prim algorithm is a greedy algorithm used to find a minimum spanning tree (MST) on a weighted graph. In the context of electricity networks, MST represents the optimal network configuration that connects all points (houses) with the shortest cable length. The Prim algorithm works by selecting repeatedly the edge (cable) with the smallest weight (length) that connects the node (house) that has not been connected to the minimum spanning tree being built. This approach ensures that the algorithm efficiently explores the graph and identifies the optimal solution.

Building an Electric Network Model with Graph

The PT Inalum housing electricity network in Block-P is represented as an undirected weighted graph. Each house in the block is represented by a node (vertex) in the graph, and each electric cable is represented by an edge (link) that connects the two nodes. The weight of each edge represents the length of the electric cable that connects the two houses. This graph-based representation enables the application of graph theory and algorithms to analyze and optimize the electricity network.

Analysis and Results

This study analyzed the Block-P electricity network using the Prim algorithm and compared the results with the previously installed power cable configuration. The key findings of this study are:

Cable Length Saving

The Prim algorithm produces optimal solutions with shorter cable lengths compared to existing configurations. This means significant savings in material and labor costs in the construction of electricity networks. By reducing the length of electric cables, the algorithm can help minimize the environmental impact of electricity network construction and reduce the financial burden on homeowners.

Energy Efficiency

Optimal electricity network configurations can minimize power loss and increase system efficiency. This can have a positive impact on energy consumption and electricity costs. By reducing energy losses, the algorithm can help reduce greenhouse gas emissions and contribute to a more sustainable energy future.

Ease of Maintenance

Optimal network configurations can facilitate the maintenance and repair process if there is damage in the future. By reducing the complexity of the network, the algorithm can help minimize the time and resources required for maintenance and repair, ensuring that the electricity network remains reliable and efficient.
