Abstract

Dedication has potential in terms of region, physical, social, economic and environmental. Opportunities are still wide open to process plastic waste into other products such as plastic waste as the basic material for making plastic bricks or paving blocks as the main material and the mix of available plastic waste in waste banks is estimated to increase every year. It is hoped that the aim of the service will be a sustainable program and can become a selling point to produce an independent village and can process plastic waste into basic material for paving blocks to support village development as a substitute for sand and cement so that all plastic waste does not end up in piles in waste management and landfills. . The data analyzed is the result of combustion residue on plastic where the plastic deposits after evaporating cannot be used again, therefore we use the plastic deposits in the paving block pressing process. After implementing the treatment, the processing of these plastic paving blocks using a pyrolysis and melting process in a mold mixed with used oil is very effective, where PET is very hard and takes a long time to melt, while LDPE is very easy to decompose and melts when mixed with used oil, whereas HDPE plastic is very easy to use. melted but very fragile in the mold. Where the inside of the paving is still not completely dry and the drying process is quite long. However, this type of PET plastic is very strong, sturdy and heavy. This is because the related tests have not been carried out to test the hardness of paving and materials as well as testing during floods where this paving is relatively lighter than cement paving on the market. Therefore, it is necessary to carry out chemical tests for paving mixed with PET LDPE and HDPE. In this case the Service only carries out treatment of plastic which has been a waste problem until now for special development and infrastructure needs by utilizing non-organic waste.

Abstract

This study aims to optimize the thermal performance of a parallel-type solar water heating system employing six flat-plate solar collectors with stainless steel pipes. Experimental testing was conducted in Pontianak City, Indonesia, under tropical equatorial conditions during three time sessions from 11:00 AM to 2:00 PM. The system was designed as a passive configuration to enhance heat absorption and uniform flow distribution. Data were recorded at 5-minute intervals, including water temperature variation, solar radiation intensity, and thermal efficiency. The results indicate that the water temperature increased significantly with a temperature difference (ΔT) ranging from 3.4˚C to 13.6˚C, while the thermal efficiency varied between 1.74% and 6.31%, reaching its maximum during the 1:00–2:00 PM session. Solar radiation intensity was observed in the range of 65–89 Lux, which showed a direct influence on system performance. Although efficiency decreased slightly under high thermal load conditions, the overall results demonstrate that the proposed parallel collector configuration performs effectively even in the afternoon period. These findings confirm that a parallel-type flat-plate solar water heater using stainless steel pipes has strong potential as an energy-efficient and environmentally friendly water heating system for tropical regions.

Abstract

The utilization of solar energy through solar panels as a source of electrical energy for households and street lighting is increasing rapidly. However, solar panels face problems related to working temperature. When the absorption of solar radiation is too high, it results in a decrease in efficiency. High temperatures cause solar panels to produce lower energy than in cold conditions. Therefore, the purpose of this study was to explore the effect of aluminum cooling fins on solar panels, with variations of fin inclination angles of 30° and 45°, and compared with panels without a cooling system to reduce the working temperature of solar panels by using cooling fins and air blowing media. The results showed that at an angle of 30°, the panel temperature was 43.60°C at the 13th iteration, with a temperature drop of about 3.13%. At an angle of 45°, the temperature obtained was 41.80°C with a temperature drop of about 6.68%. Meanwhile, the uncooled condition reached a maximum temperature of 44.40°C. No cooling causes the panel temperature to be higher, and the 45° angle provides a better cooling effect than the 30° angle, although the difference is not very significant when compared to the uncooled condition.
