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

Mushroom production requires a specially designed medium for mushroom growth. Factory-scale composting methods utilize several media, which involve water to maintain moisture and chemical/organic fertilizers. The water used for mushroom cultivation contains hazardous substances, which, if dissolved and flowing into sewers, water sources, or community irrigation, can cause several problems, resulting in liquid pollutants. The purpose and main contribution of this research is to develop and implement pollutant monitoring system in mushroom factory liquid waste based on Arduino with the integration of four sensor parameters. The 4D method used includes the stages of define, design, develop, and disseminate. The goal is to develop pollutant monitoring system using four sensors. The feasibility analysis results have a percentage above 80% in the good category and are suitable for use. Accuracy analysis results are >80% in the good category. Temperature and pH also tend to be stable without significant changes. The pH value tends to be stable in the neutral range of 7.2–7.3, which is generally still suitable for supporting the survival of aquatic organisms. The dissolved oxygen (DO) levels in water are generally low, in the range of 2.46 to 3.01 mg/L, which is already below the standard for good water quality (generally >5 mg/L). Meanwhile, the turbidity parameter indicates pollution, marked by very high turbidity reaching 300 NTU. Then it shows a drastic decrease from very high conditions at the beginning of 300 NTU to approaching zero after further distance, indicating an effective natural sedimentation process in improving water clarity.
