Abstract

Lopo is one of the village in Batudaa Pantai District and the center of the communitys socio economic activities. The major source of livelihood for the people in Loopo Village is by utilizing local potential in the coastal area so that majority of the fisherman with category of living below the poverty line. Thus, a literature review was carried out to suumarize stages and processes for developing coastal economic potential and environmental management as well optimizing creative economic potential as an effort to improve quality of life for the coastal communities of Lopo Village, which includes the use of advanced materials recharge energy bank was made from silicon solar panel. The results program was a form installation of solar energy bank 220 Voltage that can be used by fisherman. The society had used continuously which the product was a result by this program. This tool is very useful for fishing activities at sea at night because it is a lighting tool to replace the flashlights that fishermen have been using.

Abstract

Thermoelectric Generator (TEG) is an energy conversion device used as an electricity generator to create hot electric currents through temperature differences. This research aims to determine the effect of time on temperature differences from burning rice husks (Oryza sativa L.) in series and parallel configurations. This research method was carried out experimentally by burning rice husk biomass in a kiln and utilizing the heat of the fire to convert it into electrical energy. The TEG total of 48 TEG pieces which produce the highest current in the series configuration produces the highest with respective values ​​of current 0.09 A and voltage 1.02 V, and the parallel configuration TEG produces the highest with respective values ​​of current 0.98 A and voltage 0.25 V. The highest temperature difference reaches 30.5°C in the series configuration and 31.8°C in the parallel configuration. The longer the burning time, the more significant the resulting temperature difference. Likewise, the greater the electric current and voltage, the longer the burning time.

Abstract

Perpindahan kalor adalah energi yang bergerak dari suatu tempat ke tempat lain akibat perubahan suhu dalam suatu sistem atau objek. Perpindahan kalor dapat terjadi melalui konduksi, konveksi, dan radiasi, dengan perpindahan secara konduksi terjadi karena suhu yang lebih tinggi pada suatu objek berpindah ke tempat dengan suhu lebih rendah. Penelitian ini bertujuan untuk mensimulasikan perpindahan kalor secara konduksi dua dimensi pada medium pelat aluminium menggunakan metode Forward Time Central Space (FTCS). Simulasi dilakukan melalui analisis numerik menggunakan software MATLAB, dengan perbandingan terhadap solusi analitik untuk mengevaluasi distribusi perpindahan kalor yang terjadi. Hasil simulasi menunjukkan distribusi perpindahan kalor yang divisualisasikan serta tingkat keakuratan metode numerik FTCS dibandingkan solusi analitik. Persentase keakuratan yang diperoleh sebesar 65,19%, menunjukkan bahwa metode FTCS kurang optimal untuk simulasi perpindahan panas dua dimensi pada pelat aluminium. Studi ini memberikan kontribusi dalam memahami keterbatasan metode FTCS dalam simulasi numerik perpindahan kalor dan mengusulkan potensi metode alternatif untuk akurasi yang lebih baik.

Abstract

An effective way to address the plastic waste problem is by minimizing the use of non-biodegradable plastics. One approach is to develop biodegradable plastic packaging that is environmentally friendly. This research used Goroho banana peel starch, this type of banana is used because it has good potential with a starch content of 80.89%. In this research, variations in ZnO concentration of 1%, 2%, 3%, 4%, and 5% w/w were conducted. This research aims to determine the characteristics of physical properties of bioplastics with the addition of ZnO. This research uses a laboratory experimental method through several processes, namely goroho banana peel starch extraction and bioplastic manufacturing. The results indicated that varying concentrations of ZnO significantly influenced the physical and biodegradation properties of the bioplastic products. The physical properties of the bioplastics produced have met the Indonesian National Standard (SNI) for water uptake of 21.5% and biodegradation of 60 days. FTIR results show that the functional groups of bioplastics are identical to the constituent functional groups, namely starch, so that their properties resemble the properties of their constituents, which are easily degraded. The most optimum bioplastic is BPZ 2 with the addition of ZnO at 2% w/w, which produces water uptake of 1.859% and degradation time of 12 days.

Abstract

This study aims to evaluate the thermal performance of green canopies in public green spaces (RTH), both outdoors and indoors, as an environmentally friendly solution. The method involved measuring temperature and humidity over a five-month period with four observation intervals. The data were analyzed using the Temperature-Humidity Index (THI) and compared with thermal comfort standards based on the Indonesian National Standard (SNI). The results show that at 0% plant coverage, the THI values fall into the "comfortable to slightly uncomfortable" category during the period from 19:00 to 08:00. In contrast, at 81.25% plant coverage, THI values remain in the "comfortable to slightly uncomfortable" range from 21:00 to 09:00. Relative humidity met the SNI standard of 75%. Furthermore, the outdoor temperature decreased by 4.9 °C, while the indoor temperature decreased by 3.5 °C. These findings indicate that the presence of green canopies, particularly in private green spaces, significantly reduces both outdoor and indoor temperatures as the percentage of plant coverage increases.Keywords: Public Green Space, Green Canopy, Temperature Humidity Index, Indonesian National Standards
