Abstract

Energi fosil adalah energi yang paling banyak digunakan, namun ketersediaan bahan bakar fosil semakin menipis. Energi terbarukan dapat digunakan sebagai salah satu pemenuhan energi. Panel surya adalah salah satu energi terbarukan yang bekerja dengan mengubah energi matahari menjadi energi listrik. Pemanfaatan panel surya biasanya dihubungkan langsung dengan beban tanpa konverter pada tegangan rendah. Digunakan boost converter untuk menaikkan tegangan DC. Tegangan keluaran panel surya tergantung pada iradiasi dan beban yang disuplai panel surya. Untuk menjamin tegangan keluaran panel surya konstan, diperlukan umpan balik tegangan pada konverter DC-DC. Pada Penelitian ini dirancang boost converter mengunakan umpan balik tegangan pada panel surya. Tahapan perancangan diawali menghitung komponen boost converter, verifikasi menggunakan software PSIM dan implementasi perangkat keras. Boost converter telah berhasil dibuat dan mampu menghasilkan tegangan keluaran lebih besar sebesar 21,9 – 41,8 volt. Penguatan boost converter dari duty cycle 0%-80% adalah 0,96 – 5,56. Dari pengujian menggunakan umpan balik tegangan variasi iradiasi, beban, iradiasi dari matahari, dan partial shading, tegangan keluaran konverter mampu dijaga konstan 24 volt dengan error rata-rata 0,36%, 0,35%, 0,95%, dan 0,11%. Efisiensi rata-rata boost converter tanpa umpan balik tegangan 85,37% dan dengan umpan balik tegangan 90,26%.

Abstract

This study presents a comprehensive bibliometric review of scholarly literature on agile methodologies within the context of information systems (IS) development, covering publications from 2000 to 2025. Using the Scopus database as the primary source, a total of relevant articles, conference papers, and reviews were analyzed through performance analysis and science mapping techniques with VOSviewer. The findings reveal that information systems development, information management, and software engineering are the most central and frequently occurring themes, acting as conceptual anchors for the field. Co-occurrence analysis identifies three thematic clusters: (1) technological and infrastructure dimensions, focusing on computational tools, artificial intelligence, and decision support systems; (2) organizational and managerial aspects, encompassing knowledge management, risk management, and user participation; and (3) software engineering and design methodologies, including agile frameworks and cross-domain applications. Overlay visualization indicates a thematic shift from early technical foundations toward broader socio-technical and strategic considerations, while density mapping highlights emerging areas such as agile manufacturing systems and outsourcing. Co-authorship and country collaboration networks show strong global research connectivity, with the United States, United Kingdom, and China leading in output and collaboration influence. The study contributes to both theory and practice by providing a structured knowledge map that integrates technical, organizational, and strategic perspectives of agile IS development, offering guidance for future research and practical implementation. Limitations include reliance on a single database, keyword-based search constraints, and the quantitative nature of bibliometric methods.

Abstract

This study examines the effects of ChatGPT integration, team collaboration, and communication patterns on student project performance in a Software Engineering Practicum course at a private university in West Java, Indonesia. The emergence of generative AI tools such as ChatGPT presents new opportunities for enhancing learning engagement and teamwork in higher education. Using a quantitative approach, data were collected from 150 students through a Likert-scale questionnaire, and analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS 3). The findings reveal that ChatGPT integration has a significant positive impact on both team collaboration and communication patterns, which in turn strongly influence project performance. Among all variables, communication patterns emerged as the strongest predictor of success, followed by team collaboration and ChatGPT integration. Furthermore, team collaboration mediates the relationship between ChatGPT use and project performance, indicating that AI tools are most effective when embedded within social learning processes. The model demonstrated high explanatory power (R² = 0.790) and strong predictive relevance (Q² = 0.785). These results highlight that ChatGPT acts not as a replacement for human effort, but as a cognitive collaborator that strengthens teamwork and communication, ultimately enhancing learning outcomes in AI-assisted project-based education.

Abstract

The distribution system is divided into primary and secondary distribution networks. The primary distribution network is the network from the main substation transformer (GI) to the distribution substation, while the secondary is the channel network from the distribution substation transformer to the consumer or load. The primary distribution network is better known as the medium voltage network (JTM 20kV) while the secondary distribution is the low voltage network (JTR 220/380V). The distribution network is the part of the electric power system that is closest to customers or loads compared to the transmission network. Currently, network electricity conditions throughout Indonesia are experiencing a decline of 5% which is due to various factors such as the medium-scale diameter of the conductors used, so at the farthest SR the value of overvoltage is 10%, the allowable voltage drop and must anticipate an increase in electrical load of 22.7 %, the placement of the transformer is not optimal and the distance the electrical energy travels from the transformer to the load is not paid enough attention so that the capacity of a transformer is not optimal and the voltage drop is also greater. Given these conditions, re-evaluation and planning is needed that takes into account planning criteria such as allowable voltage drops and continuity of electricity services so that optimization of the network used can emerge.

Abstract

Di Indonesia dengan tuntutan energi listrik yang terus meningkat, produksi bahan bakar yang berupa batu bara dan minyak bumi mungkin akan mencapai batasnya dalam beberapa dasawarsa, disertai peningkatan sejumlah kasus cuaca ekstrim dan pemanasan global. Oleh karena itu, perlu dicari semacam solusi terhadap pemenuhan listrik dengan pemanfaatan energi alternative terbarukan yang cukup berpotensi di Indonesia. Salah satu energi alternatif terbarukan yang saat ini adalah penggunaan teknologi turbin angin dimana energi angin yang diperoleh bebas dari alam, akan diubah sedemikian rupa hingga menjadi energi listrik. Dalam tesis ini dipelajari tentang efek dari penggunaan turbin angin dengan jarak hub yang berbeda di sebuah wilayah produksi pembangkitan listrik tenaga angin, untuk mencari jarak dan jumlah turbin terbaik yang digunakan. Disajikan sebuah formulasi matematis dalam membangun sistem multi-turbin. Mengingat turbin angin dengan jarak dan jumlah turbin yang bervariasi maka model tersebut diselesaikan menggunakan metode Algoritma Particle Swarm Optimization (PSO). Dengan hasil konfigurasi turbin yang terbaik akan diperoleh biaya yang minimum dan  pembangkitan daya yang maksimum.

Abstract

Integrasi Continuous Emission Monitoring System (CEMS) pada Gas Turbine Compressor (GTC) ke dalam Sistem Informasi Pemantauan Emisi Kontinu (SISPEK) Kementerian Lingkungan Hidup dan Kehutanan (KLHK) menjadi langkah penting bagi PT Donggi-Senoro LNG dalam memastikan pemantauan emisi yang akurat dan kontinyu. Penelitian ini bertujuan untuk mengevaluasi proses integrasi CEMS di 3 GTC yang terpasang di fasilitas tersebut, yang bertujuan mendukung kepatuhan terhadap regulasi emisi di Indonesia. Hasil penelitian menunjukkan bahwa setelah integrasi, pemantauan emisi real-time melalui CEMS mengalami peningkatan signifikan dalam hal keandalan dan akurasi data. Kesalahan yang disebabkan oleh input manual dapat diminimalkan, sementara pengiriman data otomatis ke SISPEK memastikan perusahaan mematuhi persyaratan pelaporan pemerintah. Selain itu, sistem ini mampu mendeteksi anomali atau penyimpangan emisi lebih cepat, memungkinkan respon yang lebih cepat untuk menjaga kualitas operasi. Secara keseluruhan, integrasi CEMS ini tidak hanya berkontribusi pada peningkatan efisiensi operasional, tetapi juga mendukung upaya keberlanjutan lingkungan dan pemenuhan standar regulasi emisi yang ditetapkan oleh KLHK, yang semakin memperkuat komitmen perusahaan terhadap kelestarian lingkungan. Kata kunci: CEMS, SISPEK, Gas Turbine Compressor, emisi, PT Donggi-Senoro LNG, pemantauan lingkungan
