Abstract

The battery is a back-up for the DC electrical system which is closely related to the protection system in a generator, so to find out the routine maintenance system of the 110 VDC battery system used at the Mount Wugul PLTM. This maintenance will measure the voltage and quality of the battery water in the battery. The aim of the research is to test the 110 VDC battery for daily maintenance, a visual inspection is carried out to ensure the physical condition of the battery is in good condition, to ensure the 110V DC battery remains in a stable condition and is ready to supply DC power to auxiliary equipment when an emergency occurs. From the test results, it was found that the voltage drop in cells number 1 and 7 was recorded at 0.3661 VDC and 1.1948 VDC respectively. It was necessary to take corrective action or replace the battery cells. By measuring the specific gravity of each battery cell, the average value of the specific gravity of the battery was 1,214.59, which is included in the recharge category, meaning that the battery needs to be re-charged. So the results of measuring these two voltages show that the respective voltage balance between positive to ground and negative to ground is in accordance with standards

Abstract

This study aims to examine the effectiveness of the Green Science Learning model integrated with the local wisdom values of the Pancurawis Temple myth in developing environmental care attitudes among early childhood students. The research was conducted at TK Masyitoh Miftahul Huda Langkap, Bumiayu District, during the even semester of the 2024/2025 academic year using a quasi-experimental design with a nonequivalent control group design. The research subjects consisted of two groups: an experimental group that utilized Green Science Learning oriented toward the Pancurawis Temple myth, and a control group that used conventional learning methods. The research instrument was an observation sheet measuring children's environmental care attitudes. The results showed a significant difference between the experimental and control groups (t = 4.927, p < 0.05). The mean score of the children’s environmental care attitude in the experimental group was higher (M = 84.60) than that of the control group (M = 69.80), with an effect size of 2.03 (categorized as very large). These findings confirm that integrating local wisdom values into the Green Science Learning model is effective in fostering environmental care attitude from an early age.
