Metode (P&O) memiliki keterbatasan meningatkan efisiensi dan memiliki masalah osilasi, kecepatan pelacakan titik daya maksimum, konvergensi terutama saat mengalami perubahan kondisi atau radiasi cepat. Penelitian ini dilakukan untuk melihat kinerja algoritma perturb and observe dan melakukan modifikasi untuk meningkatkan kinerjanya mengatasi osilasi, konvergensi, efesiensi pelacakan serta kecepatan pelacakan. Kinerja dari algoritma akan di lihat melalui simulasi dan dievalusi untuk melihat seberapa besar peningkatan kinerja yang dapat di capai dari menggunakan algoritma P&O yang di modifikasi. Simulasi mununjukkan algoritma P&O modifikasi memiliki keungulan dari P&O konvensional. Maximum Power Point Tracking (MPPT) is a technique to optimize the power from photovoltaic. The perturb and observe algorithm MPPT is a widely used and fairly simple method. P&O method has limitations to increase efficiency and has oscillation problems, maximum power point tracking speed, convergence especially when experiencing rapid changes in condition or radiation. This reserch is conducted to see the performance of the perturb and observe algorithm and make modifications to improve its performance to overcome oscillations, convergence, tracking efficiency and tracking speed. The performance of the algorithm will be seen through simulation and evaluated to see how much performance improvement can be achieved from using the modified P&O algorithm.

Abstract

Penelitian ini bertujuan untuk mengevaluasi kinerja algoritma MPPT dengan metode P&O konvensional dan modifikasi pada sistem photovoltaic. Pengujian dilakukan dengan variasi iradiasi 200-600 W/m². Hasil menunjukkan metode P&O modifikasi mengurangi osilasi dan meningkatkan waktu pelacakan. Pada iradiasi 600 W/m², metode modifikasi mencapai MPP dalam 325 ms dengan daya 9.85 W, sedangkan konvensional memerlukan 345 ms dengan daya 8.775 W. Peningkatan iradiasi berbanding lurus dengan daya output dan berbanding terbalik dengan waktu pelacakan MPP. Penelitian ini membuktikan efektivitas metode P&O modifikasi dalam meningkatkan efisiensi dan stabilitas sistem MPPT pada aplikasi photovoltaic. This study evaluates the performance of Maximum Power Point Tracking (MPPT) algorithms using conventional and modified Perturb and Observe (P&O) methods in photovoltaic systems. Tests were conducted across irradiance levels of 200-600 W/m². Results demonstrate that the modified P&O method significantly reduces oscillations and improves convergence speed compared to the conventional approach. At 600 W/m² irradiance, the modified method achieves MPP in 325 ms with 9.85 W power output, while the conventional method requires 345 ms, producing 8.775 W. Increased irradiance correlates positively with power output and negatively with MPP tracking time. This research validates the effectiveness of the modified P&O method in enhancing efficiency and stability of MPPT systems in photovoltaic applications.

Abstract

This research aims to optimize the performance of a photovoltaic system using the Incremental Conductance algorithm (INC). The incremental conductance method is susceptible to oscillations in the steady state and tracking accuracy under solar radiation variations. This research investigates how Incremental conductance can be modified to improve its performance in reducing oscillations and accelerating cycle speed. Tests were carried out at irradiation variations of 200, 400 and 600 W/m². The INC method produces conventional tracking times of 500 ms, 555 ms, and 300 ms with maximum power of 1.89 W, 5,542 W, and 8,232 W at increased irradiation. Meanwhile the INC modification method shows a significant improvement with tracking times of 345 ms, 330 ms, and 205 ms, producing maximum power of 2.73 W, 7.36 W, and 9.9 W. When reducing irradiation, the modification method achieves tracking times of 195 ms and 455 ms. These results show that the INC modification method is superior in reducing oscillations, speeding up tracking time, and producing higher maximum power so as to increase the overall efficiency of the photovoltaic system

Abstract

This paper presents the design and implementation of a single-phase five-level inverter using the Cascaded H-Bridge (CHB) topology. The primary objective of this research is to evaluate the inverter’s performance based on the Total Harmonic Distortion (THD) of the output voltage waveform under resistive load conditions. The proposed system consists of two H-Bridge modules powered by independent 23 V DC sources, controlled by an Arduino Mega 2560 and supported by gate driver circuits. The inverter is tested using incandescent lamp as the load. The results show a clearly stepped five-level AC output waveform, characteristic of CHB inverters. THD analysis indicates a distortion level of approximately 12.72%, which is higher than the IEEE 519 standard for sensitive equipment but acceptable for general resistive applications. The results confirm the feasibility of CHB-based inverter construction for practical use, while also highlighting opportunities for further optimization, especially in reducing harmonic content. This work contributes to the field of power electronics by providing a practical foundation for developing low-THD, cost-effective multilevel inverters.

Abstract

This study aims to analyze the regional development strategy of Bukittinggi City based on the Regional Revenue and Expenditure Budget (APBD) for 2024 and its budget allocation changes. The main problem of the research is how APBD changes reflect development priorities and their implications for the regional economy. This study employs a quantitative descriptive method with financial ratio analysis and comparative evaluation between the budget before and after amendments. Secondary data was obtained from official documents of the Amended Regional Budget Regulation for Fiscal Year 2024 of Bukittinggi City. The research findings indicate an increase in regional revenue of IDR 17.42 billion (2.30%), primarily from intergovernmental transfers which increased by IDR 19.17 billion (56.90%). Capital expenditure experienced a significant increase of IDR 3.36 billion (5.00%), particularly in road, network, and irrigation spending which increased by 86.52%. These findings indicate that the Bukittinggi City Government prioritizes infrastructure development as the main strategy to enhance connectivity and regional economic growth, consistent with regional development theory emphasizing the importance of capital investment in stimulating long-term economic growth.

Abstract

Anggaran Pendapatan dan Belanja Daerah (APBD) adalah alat penting untuk mewujudkan tata kelola pemerintahan yang baik (good governance), terutama dalam hal akuntabilitas dan transparansi. Tujuan dari penelitian ini adalah untuk memeriksa akuntabilitas keuangan daerah dalam pengelolaan APBD Pemerintah Kabupaten Merangin dengan melihat bagaimana perencanaan, pelaksanaan, pelaporan, dan pertanggungjawaban keuangan daerah berkorelasi satu sama lain. Penelitian ini menggunakan metode kualitatif dengan studi pustaka. Peraturan perundang-undangan, literatur akademik, laporan keuangan daerah, dan dokumen Peraturan Daerah tentang Perubahan APBD Kabupaten Merangin Tahun Anggaran 2025 diselidiki dan dianalisis. Kajian menunjukkan bahwa Pendapatan Asli Daerah (PAD) telah meningkat, defisit anggaran telah ditangani, dan alokasi belanja modal untuk pembangunan telah meningkat. Namun, pengelolaan keuangan daerah masih menghadapi banyak masalah. Beberapa di antaranya adalah ketergantungan yang besar terhadap dana transfer pemerintah pusat dan dominasi belanja operasi, terutama belanja pegawai. Akibatnya, untuk mewujudkan pengelolaan APBD yang lebih akuntabel, berkelanjutan, dan berfokus pada kemakmuran masyarakat, diperlukan peningkatan kemandirian fiskal, efisiensi belanja, dan kualitas perencanaan dan transparansi anggaran.
