Abstract

Energy wasted in the household streams can be easily found in the water faucets, showers, toilet sprinkles, and other equipment in plumbing systems where water only flows to clean out before it becomes a waste substance. Energy from flowing waters can be collected and converted to more useful forms of energy like electricity as it can be immediately utilized or stored. In the further development of the mini compact turbine generator (MCTG), the water flowing through every part of the house plumbing system is intended to be collected as electrical power. Unfortunately, the voltage produced by the conventional MCTG is insufficient for immediate applications in various electrical devices. In addition, the generated voltage does not conform to the voltage rating of the battery’s terminal as a medium for storing electrical energy. This research proposes the performance improvement of the MCTG output to produce a higher voltage by adding a DC boost converter, which can operate in a single or cascaded configuration to address issues with the MCTG output voltage and the boost converter’s efficiency when operating in high duty cycle values. Designs and simulations were conducted to obtain the expected criteria for electrical voltage generation. Several topologies tested included the single converter system, cascaded converter system, cascaded converter system with a selector, and parallel system. The results demonstrated that the parallel system worked better than the three topologies as it could yield voltage according to the reference voltage of 14 V and efficiency above 0.9 on the broader range of rotations of the MCTG rotor shaft.

Abstract

 Baterai lithium-ion-polymer atau lithium-polymer merupakan salah satu jenis dari baterai berbasis lithium-ion. Saat ini, baterai berbasis Lithium-ion banyak digunakan pada berbagai macam perangkat portabel hingga kendaraan listrik. Pengisi daya atau charger untuk baterai berbasis Lithium-ion yang umum digunakan saat ini menggunakan metode constant current – constant voltage (CC-CV). Metode ini dianggap efektif untuk menghindari undercharging dan overcharging. Pada battery pack terdapat akumulasi resistansi yang dapat menyebabkan penurunan tegangan pada cell baterai, dan dapat mempercepat proses transisi dari mode CC menjadi mode CV. Percepatan transisi tersebut dapat mengakibatkan proses pengisian daya berlangsung lebih lama. Pada penelitian ini dibahas bagaimana proses kompensasi resistansi pada charger dengan topologi PLL, untuk mengompensasi akumulasi resistansi pada battery pack pada saat proses pengisian daya berlangsung. Pada simulasi didapatkan hasil bahwa pengisi daya dengan kompensasi resistansi menghasilkan waktu pengisian daya 17.82% lebih cepat, sedangkan pada uji coba alat didapatkan waktu pengisian daya 15.58% lebih cepat, kedua hasil tersebut jika dibandingkan dengan pengisi daya dengan topologi PLL tanpa kompensasi resistansi.

Abstract

Solar Power Plants are an environmentally friendly energy source that utilizes sunlight energy which is converted into electricity. However, solar panels must maintain their performance. One of the impacts is that solar panels cannot work optimally if the temperature of the solar panels exceeds the safe temperature. This research examines the factors that cause the performance of solar panels to not work optimally, when the surface temperature of the solar panels is too hot and exceeds the safe temperature limit, then tools are needed to help the solar panels so that the working temperature is not too high. The technology used to control the temperature of solar panels is by utilizing IoT by maximizing the DS18B20 sensor and voltage sensor, to read the surface temperature of the panel, which will then wet the surface of the solar panel with distilled water and well water automatically if the surface temperature of the panel exceeds the safe temperature on the solar panel. And later you can monitor the temperature of the panel with a smartphone and also observe whether distilled water and well water can reduce the temperature on the surface of the panel. When collecting data, it can be compared to when without using cooling, the temperature on the panel is above 33 degrees. Meanwhile, when using a cooler the temperature obtained decreases. The well water cooler produces a temperature of 32 degrees, while the distilled water cooler produces a temperature of 30.5 degrees. It can be concluded that distilled water can reduce the temperature of the panel, so it can make the panel work optimally. So, in order to maximize the performance of the panels to utilize solar power, in this research, distilled water is very good for lowering the temperature on the surface of the panels.

Abstract

Kebutuhan energi yang semakin meningkat tidak sejalan dengan ketersediaan sumber energi yang ada di alam, sehingga manusia dituntut untuk terus berinovasi mencari sumber energi alternatif, termasuk juga dengan pemanfaatan energi terbuang dari suatu sistem, yang kemudin energi terbuang tersebut digunakan sebagai sumber energi untuk sistem lainnya. Penelitian mengenai pembangkit listrik portabel dengan sumber energi goncangan ini bertujuan untuk memanfaatkan energi yang terbentuk akibat adanya goncangan seperti ketika bersepeda melalui jalanan yang tidak rata, atau bahkan goncangan pada tas punggung ketika digunakan saat kita berjalan. Teori utama yang mendukung penelitian ini adalah teori Hukum Lenz dan Hukum Faraday. Hukum Lenz membahas mengenai arus akibat ggl induksi yang memiliki arah tertentu. Dalam Hukum Lenz dijelaskan bahwa arus induksi memiliki arah yang selalu menjauhi sumber medan magnet yang memengaruhinya. Pada Hukum Faraday, sumber energi yang dapat diproses untuk menghasilkan perubahan besarnya medan magnet terhadap waktu, berdasarkan pada kedua hukum tersebut, dapat dimanfaatkan untuk membangkitkan listrik.Listrik yang dibangkitkan pada penelitian ini masih sangat kecil, namun ada potensi yang perlu untuk dikembangkan lebih lanjut. Pembangkit yang digunakan pada penelitian ini ada dua jenis, pertama yaitu pembangkit dengan satu kumparan besar tunggal, kedua yaitu pembangkit dengan tiga kumparan yang terhubung seri antar-kumparannya. Pengujian tanpa beban menghasilkan tegangan terbangkit terbesar sebesar 2,07 volt pada frekuensi goncangan 240 BPM pada pembangkit dengan selongsong satu kumparan tunggal. Pengujian dengan beban menghasilkan daya terbangkit tertinggi pada saat 240 BPM yaitu sekitar 11,1 mW, dan tegangan terbesar 1,64 volt, pada selongsong satu kumparan tunggal.

Abstract

The implementation of micro-hydro power plants (MHPPs) offers a strategic solution for achieving energy independence, particularly within remote communities. This study proposes the development of a hydroelectric power generator with a vertical axis turbine, designed not only as a source of clean energy but also to minimize visual pollution. The system maximizes submerged components, thereby reducing its visual impact. Although MHPPs technology is widely applied to address electrification challenges in remote areas, the system proposed in this study, with its components predominantly submerged below the water surface, offers a visually unobtrusive solution that is also well-suited for urban environments. However, conventional locked-blade turbines often experience significant efficiency losses due to counter-flow pressure acting on blades moving against the water stream, highlighting the need for an adaptive mechanism to minimize drag and optimize energy capture. The hydroelectric power generator using vertical axis turbine with adaptive blades consistently demonstrated better performance than a system using locked blades. The adaptive-blade configuration outperformed the locked-blade system, exhibiting a 5.1% increase in average turbine efficiency and a 3.5% improvement in overall system efficiency.

Abstract

Peningkatan kebutuhan energi listrik mendorong pemanfaatan sumber energi terbarukan yang lebih efisien dan berkelanjutan. Salah satu alternatif yang memiliki potensi besar adalah Pembangkit Listrik Tenaga Surya (PLTS) terapung berbasis panel surya bifacial yang mampu memanfaatkan radiasi matahari dari kedua sisi modul. Penelitian ini bertujuan merancang dan mengimplementasikan sistem PLTS terapung berbasis panel surya bifacial pada keramba di Waduk Cengklik serta menganalisis pengaruh media reflektor terhadap karakteristik keluaran sistem. Metode penelitian meliputi perancangan sistem, implementasi perangkat keras berbasis Arduino Uno, validasi sensor PZEM-004T, serta pengujian performa menggunakan tiga media reflektor, yaitu air, seng, dan galvalum. Hasil penelitian menunjukkan bahwa sensor PZEM-004T memiliki tingkat kesalahan rata-rata sebesar 0,14% untuk tegangan, 0,80% untuk arus, dan 0,88% untuk daya sehingga layak digunakan sebagai instrumen pengukuran. Analisis performa menunjukkan bahwa media air menghasilkan daya beban rata-rata tertinggi sebesar 44,06 W dengan rugi-rugi daya terendah sebesar 4,38 W dibandingkan media seng dan galvalum. Kondisi tersebut mengindikasikan bahwa pemanfaatan radiasi pantul (albedo) dari permukaan air berkontribusi terhadap peningkatan keluaran daya panel surya bifacial. Pengujian kinerja harian selama tiga hari juga menunjukkan bahwa peningkatan intensitas radiasi matahari diikuti oleh kenaikan tegangan, arus, dan daya keluaran sistem, sedangkan pada kondisi tanpa radiasi matahari beban sepenuhnya disuplai oleh baterai. Secara keseluruhan, sistem yang dikembangkan mampu menghasilkan daya maksimum hingga 60 W, melampaui target penelitian sebesar 50 W, sehingga implementasi PLTS terapung berbasis panel surya bifacial pada keramba berpotensi menjadi solusi penyediaan energi listrik yang andal dan berkelanjutan di kawasan perairan.

Abstract

Food security and energy independence are key pillars of sustainable village development toward the Golden Indonesia 2045 vision. The "Lestari Farm" Farmers Group in Karanganyar Village, Plupuh, Sragen, faces structural constraints in expanding its integrated hydroponic and catfish aquaculture operations. Major challenges include high electricity costs for circulation pumps (accounting for 30%–35% of total operational expenses), commodity mortality risks caused by power outages, uncontrolled water quality (yielding predominantly Grade B/C products), and manual, unsegregated financial management. This partnership program aims to implement "SI-HEBAT" (Sistem Hidroponik & Perikanan Energi Baru Terbarukan / Renewable Energy Hydroponic & Fishery System) technology, which integrates a 300 Wp off-grid solar power system with an Internet of Things (IoT) ESP32-based automated nutrient control system. The methodology employed is Participatory Action Research (PAR), encompassing stages of community engagement, technology fabrication, technical training, digital management mentoring, and the establishment of a sustainability unit. The results demonstrate 100% efficiency in operational electricity costs, a reduction in crop/fish mortality rates to less than 5%, and a quality upgrade to predominantly uniform Grade A harvests. Furthermore, the partner successfully adopted digital financial bookkeeping via an app and launched rebranded, labeled product packaging.
