Abstract

Gedung Komplek Badan Pendidikan Kristen PENABUR Harapan Indah merupakan pusat data dan informasi penting sekolah, dimana tingginya penggunaan perangkat elektronik sebagai beban nonlinier menjadi penyebab utama timbulnya harmonik yang dapat mengganggu sistem distribusi kelistrikan baik kerugian secara teknis maupun finansial. Oleh karena itu, investigasi pengaruh beban nonlinier terhadap tegangan, frekuensi, faktor daya, dan THD menjadi penting untuk dilakukan pengukuran. Metode penelitian dilakukan secara eksperimen dengan menggunakan alat ukur Power Quality Analyzer Fluke 43B pada titik beban panel listrik yang telah terpasang trafo 1100 kVA, kapasitor bank 525 V 50 Hz dengan turned reactor sebagai filter harmonik pasif. Data hasil pengukuran diambil satu kali pada setiap waktu pengukuran. Hasil penelitian menunjukkan bahwa kondisi gedung mengalami ketidakseimbangan antara jumlah beban yang menyebabkan gelombang arus tidak sinusoidal dan bernilai positif akibat beban nonlinear. Namun, penggunaan trafo, kapasitor bank, dan turned reactor sebagai filter harmonik pasif memberikan dampak yang signifikan pada hasil pengukuran yaitu: nilai tegangan memenuhi standar SPLN-1-1995 tertinggi sebesar 227,1 V pada fasa T dengan batas izin antara 198-231 V; nilai rata-rata frekuensi memenuhi standar IEC sebesar < 50 Hz; nilai  memenuhi standar IEEE 519-1992 sebesar 3,41% dengan batas izin < 5%, dan nilai  memenuhi standar sebesar 7,13% dibawah batas izin < 15%; nilai faktor daya memenuhi standar SPLN 70-1 sebesar 0,98 mendekati angka1(satu) dan bernilai positif.

Abstract

Penelitian ini bertujuan untuk menganalisis koreksi faktor daya pada transformator 3 MVA yang melayani beban motor 3 fasa dengan menggunakan Kapasitor bank yang dikendalikan oleh regulator RVT2-12. Faktor daya yang rendah pada beban induktif seperti motor 3 fasa menyebabkan inefisiensi dan peningkatan biaya operasional. Dengan menambahkan Kapasitor bank dalam langkah-langkah 2x50 KVAR, daya reaktif dapat dikompensasi sehingga faktor daya mendekati nilai 1, meningkatkan efisiensi sistem. Metodologi yang digunakan dalam penelitian ini meliputi pengukuran faktor daya awal, perhitungan daya reaktif yang dibutuhkan untuk mencapai faktor daya target, dan penentuan jumlah langkah Kapasitor bank yang diperlukan. Simulasi penambahan Kapasitor bank dilakukan untuk melihat perubahan faktor daya, diikuti dengan implementasi kontrol otomatis menggunakan RVT2-12 untuk mengatur penambahan atau pengurangan Kapasitor bank berdasarkan kebutuhan sistem. Hasil penelitian menunjukkan bahwa dengan penambahan 6 langkah Kapasitor bank (setara dengan 600 KVAR), faktor daya dapat ditingkatkan dari 0,77 menjadi 0,89. Implementasi RVT2-12 memastikan penyesuaian yang tepat dan efisien terhadap perubahan beban, menjaga faktor daya dalam kisaran yang diinginkan secara otomatis. Kesimpulannya, penambahan Kapasitor bank yang dikendalikan oleh regulator RVT2-12 terbukti efektif dalam meningkatkan faktor daya dan efisiensi sistem tenaga listrik pada transformator 3 MVA dengan beban motor 3 fasa. Studi ini memberikan panduan praktis untuk implementasi koreksi faktor daya dalam aplikasi industri, mengurangi inefisiensi dan biaya operasional yang terkait dengan faktor daya rendah.

Abstract

Energy transportation and distribution are crucial components in the national energy system, serving as the main link between energy sources and consumers. The efficiency of both systems is crucial to maintain the stability of energy supply and minimize energy loss during the distribution process. This study aims to explore the importance of energy transportation and distribution in the context of national energy security and the geographical and energy infrastructure challenges in Indonesia. Using a literature study method, this study collects and analyzes literature from various academic sources and relevant reports. The results show that an efficient energy transportation and distribution system plays a major role in reducing the energy gap between regions, expanding energy access to remote areas, and supporting sustainable economic development. In addition, Indonesia's geographical challenges as an archipelagic country, such as the distance between islands and population inequality, widen the energy infrastructure gap between the western and eastern regions. Investment in energy infrastructure development, especially in disadvantaged areas, and the integration of renewable energy are important steps in strengthening national energy security. This study concludes that in order to achieve better and more equitable energy security, inclusive and sustainable energy infrastructure development policies and strategies are needed.

Abstract

According to research published in the Journal of Applied Phycology, algae have the ability to produce biofuels with five times higher energy efficiency compared to soybean plants, making it a highly efficient and sustainable option for renewable fuels. The goal of this research is to use biotechnology to create biofuels from algae as a renewable energy. This study used a laboratory experimental design with a quantitative approach. Population: Microalgae or green algae that have high potential in lipid production, such as Chlorella vulgaris or Spirulina platensis, which are commonly used in biofuel research. Sample: Several species of algae were selected to test their effectiveness as biofuels, including genetically engineered species and natural species as a comparison. The results of the ANOVA analysis showed significant differences in lipid levels between treatment groups. The results of the T/Post-hoc test confirmed that the genetically engineered species had higher lipid levels, supporting the efficiency of biofuels. The regression results showed a strong positive correlation (R² = 0.68), which supports other studies that found that microalgae can produce biomass in a relatively short time with a controlled environment, making it efficient for large-scale biofuel production. The conversion efficiency of lipids to biofuels reached 85.5%, indicating that the transesterification method used in this study is very effective in converting algae lipids to biodiesel. The use of biotechnology in the production of biofuels from algae has great potential as an efficient and sustainable renewable energy source.

Abstract

The global transition toward low-carbon energy has positioned hydrogen (H₂) as a key renewable fuel, particularly for applications in fuel cells that require ultra-high purity. Ensuring hydrogen quality is essential to prevent catalyst poisoning and system degradation, as defined in ISO 14687:2019 standards. This study presents a simulation-based analysis of hydrogen purity using a Gas Chromatography–Mass Spectrometry (GC–MS) modeling approach to evaluate three production pathways: green hydrogen (from electrolysis), grey hydrogen (from steam methane reforming), and a fuel cell–grade feedstock.The simulation predicts impurity profiles such as O₂, N₂, CO, CO₂, CH₄, sulfur compounds, and water vapor, comparing each with ISO threshold limits. Results indicate that green hydrogen generally complies with ISO standards, while grey hydrogen exceeds CO₂ and sulfur limits. The fuel cell–grade sample shows near-complete conformity due to simulated purification processes such as pressure swing adsorption.These findings highlight that analytical modeling can effectively predict hydrogen quality and compliance potential across different production routes. The study emphasizes that advancing hydrogen technology requires not only cleaner production methods but also reliable analytical simulations to support quality assurance and sustainability in future hydrogen economies.
