Abstract

This research aims to evaluate the comparison of two power conversion methods, utilizing diodes and thyristors, in circular saw machines used in the furniture industry. The research used a quantitative approach through controlled experiments, testing five machines from each method based on power consumption, cutting speed, and cutting productivity. The test results showed that machines with thyristor-based power conversion showed higher cutting speed and productivity compared to diode-based machines, although their power consumption was slightly higher. Statistical analysis using Welch’s t-test indicated no significant difference in energy efficiency between the two methods. This study recommends the use of thyristor power conversion for industrial applications that require high speed and productivity, while the diode method is more suitable for low-power requirements.

Abstract

The Human Development Index (HDI) is an important indicator for assessing the success of regional development, particularly in the aspects of health, education, and economy. However, as an aggregate indicator, HDI cannot yet specifically represent the unique development needs of each region. Therefore, a decision support system (DSS) approach is needed to analyze HDI components more deeply and objectively. This study aims to compare two multicriteria decision-making methods-Simple Additive Weighting (SAW) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS)-in ranking the HDI of regencies/cities in Central Java Province in 2024. The HDI data was obtained from the Central Statistics Agency (BPS) 2024, covering the three main dimensions of HDI. The analysis results show differences in ranking orders between the two methods, indicating that the choice of analytical method can influence development interpretations and priorities. This study makes a significant contribution by providing a data-driven approach to support more targeted regional development policies.
