Abstract

Overheating can significantly reduce the efficiency and power output of solar panels, leading to the development of various cooling techniques. This paper compares four cooling methods: heatsink with fan, fin heatsink, water cooling, and floating solar panels. The study evaluates these methods based on temperature reduction, cooling efficiency, electrical performance, and practical considerations. Active systems, like water cooling and heatsink with fan, showed higher performance improvements but required more resources and were more complex to operate. On the other hand, passive systems such as fin heatsink, and floating panels offered simpler and more sustainable solutions with moderate efficiency gains. This review highlights the balance between efficiency, sustainability, and practicality, providing valuable insights for choosing the best cooling method for solar panels. The findings also point to future opportunities for advancements through hybrid systems and new materials to enhance performance and sustainability in solar energy systems.

Abstract

Dye-Sensitized Solar Cells (DSSCs) have garnered significant attention due to their cost-effectiveness and potential for sustainable energy applications. TiO2 and ZnO nanostructures are widely employed as photoanodes, given their unique optical and electronic properties. This paper compares the findings of ten studies with similar research scopes, highlighting enhancements in DSSC efficiency using modified TiO2 and ZnO. Results are presented through comparative analysis and graphical representations, focusing on energy conversion efficiency. Through a detailed comparative analysis, this research identifies key trends and material innovations for advancing DSSC technology. Currently from these studies TiO2 with synthesis dye still hold the highest efficiency compared to ZnO and Synthesis TiO2/ZnO nanocomposite whether using synthesis and natural dye and by using counter electrode of Mg and Fe in TiO2 based have the least efficiency. DSSCs efficiency still lower than silicon based and thin-film solar cells but have the potential to be the cheapest solar cells. DSSCs need to improve efficiency to be able to go to marketplace and it needs further research and combination of dye and counter electrode or even the new breakthrough.

Abstract

The shift to renewable energy faces the challenge of intermittency, which requires effective Energy Storage Systems (ESS). Sand-Based Thermal Energy Storage (TES) presents a cost-effective and environmentally friendly solution, although it suffers from the low thermal conductivity of sand. This research seeks to enhance the thermal efficacy of sand batteries by incorporating waste iron shavings from lathes as a composite material and examining its suitability for pilot-plant scale heating.A 96-liter sand battery container was used with varying mixtures of iron waste at 0%, 10%, 20%, and 30% relative to the volume of sea sand. The charging process used a 4000-watt power supply for simulation and 4000 Wp solar panels for validation. The discharge process was implemented to provide heat to a copra drying oven. The findings indicate that incorporating waste iron significantly improves the heat transfer rate and temperature uniformity during charging. The composition with 30% iron (P-30) demonstrated the most favorable thermal properties. During discharge tests, the system maintained the copra drying oven temperature within 56-57°C for over 12 hours, meeting the required drying temperature standards. This study proves that sand batteries with a waste iron composite represent an effective, cost-effective, and sustainable TES solution for thermal applications in the context of renewable energy.

Abstract

This service activity provides benefits to CV Pandawa Farm, because it uses cow dung into environmentally friendly fuel energy. Sarnubi CV Pandawa Farm's Cattle Farm is a cattle farm that has been established for more than 10 years. more than 30 individuals. The location of this farm is in the Sukawinatan area which is not far from the Palembang City Waste Landfill. The environmental conditions of this farm are not good because health management of cow dung has not been implemented here. Processing cow dung into biogas can have a good impact on the environment because it maintains environmental cleanliness. Apart from that, biogas can be used to replace fossil fuels. CV Pandawa Farm does not yet understand how to process cow dung into biogas. In this socialization, counseling was provided by providing knowledge and understanding of how to process cow dung waste combined with tofu industry waste into biogas using a Fixed Dome Digester

Abstract

Hidrogen merupakan gas ramah lingkungan yang dapat dihasilkan melalui proses elektrolisis air untuk memisahkan hidrogen (H₂) dan oksigen. Pada penelitian ini digunakan elektroliser sel kering dengan membran polyvinyl alcohol (PVA) sebagai pemisah antara dua elektroda baja tahan karat 316 guna memperoleh komposisi hidrogen yang lebih tinggi. Penerapan membran PVA terbukti mampu meningkatkan produksi hidrogen secara signifikan dibandingkan tanpa penggunaan membran. Selain itu, pemanfaatan elektrolit KOH dalam proses elektrolisis mampu meningkatkan arus listrik, yang secara linier berbanding lurus dengan kenaikan kebutuhan daya listrik serta menghasilkan produksi gas hidrogen yang lebih besar. Gas hidrogen yang dihasilkan kemudian dikonversi menjadi energi listrik menggunakan sel bahan bakar hidrogen untuk menyuplai stasiun pengisian daya dan telepon sebagai beban, dengan status pengisian dikategorikan berhasil (CS) atau gagal.

Abstract

Indonesia's dependence on fossil fuels underscores the need for the development of environmentally friendly alternative energy sources. This research examines the utilization of rotten tomato waste (Solanum lycopersicum) and starfruit (Averrhoa bilimbi L.) juice as natural electrolytes in the production of bio-batteries, with the addition of potassium hydroxide (KOH) to enhance their performance. Both materials contain organic acids such as citric acid and ascorbic acid, which support electrochemical reactions. The experimental variations included electrolyte solution volumes of 200–400 mL and KOH concentrations of 0.1 M, 1.0 M, and 2.0 M. The parameters tested included pH, conductivity, voltage, current, power, capacity, and the duration of the LED light, as specified in SNI IEC 60086-1:2015. The results show that for rotten tomato extract, the optimal combination of 350 mL with 2.0 M KOH yields the highest conductivity of 15.37 mS/cm and a capacity of 2.87 mAh. For starfruit juice, the optimal combination of 200–250 mL with 1.0 M KOH provides the highest capacity. The addition of KOH generally increases conductivity and power output, but high concentrations (2.0 M) in starfruit extract reduce efficiency due to over-ionization. This research proves that rotten tomato waste and starfruit juice with the addition of KOH have the potential to be efficient, inexpensive, and environmentally friendly bio-battery raw materials and support the utilization of organic waste as a renewable energy source.
