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

Solar panel sumbernya diambil dari energi matahari yang fluktuatif dengan kondisi alam, maka dibutuhkan konverter untuk menaikan dan menurunkan tegangan untuk menyesuaikan kebutuhan perangkan yang akan digunakan. Berkaitan dengan itu tujuan riset mengebangkan dan mendesain Buck-Boost Converter yang menggunakan sistem close loop tegangan diatas 12 Volt untuk solar panel. Arus searah (DC) akan diatur melalui konverter DC ke DC, ini merupakan suatu device yang mengubah/ mengkonversi energi listrik dari DC ke DC (menaikan atau menurunkan) tanpa mengubah polaritas sumber dan meningkatkan efisiensi daya. Metode penelitian melalui tahapan analisis permasalahan, desain pengembangan, unjuk kerja, evaluasi, dan kesimpulan. Analisi data kuantitatif deskriptif menceritakan data sesuai dengan keadaan sebenarnya/ kondisi nyata. Kesimpulan riset untuk pengujian konverter DC to DC system close loop untuk solar panel, berdasarkan pengujian menggunakan catu daya pada kondisi buck mampu menurunkan tegangan sampai 4,1 Volt dengan nilai error 5,707%. Pada konsisi boost mampu menaikan tegangan 54,7 Volt dengan nilai error 0,25%. Efisiensi ketika menggunakan solar panel 100 Wp pada kondisi buck dengan variasi duty cycle mempereloh nilai Vout menurun dari Vin. Kemudian kondisi boost dengan variasi duty cycle menaikan Vout dari Vin . Hal ini menunjukan sesuai dengan penelitian bahwa konverter buck untuk menurunkan dan konverter boost untuk menaikann tegangan.

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.
