“…Fitter and Hay (2001) stated that the intensity of sunlight always varies every day and depends on the season, so the wavelength received may vary. Sari et al (2015) stated that the intensity of light rises and falls based on cloud conditions in the atmosphere. The intensity of sunlight stabilizes at an intensity exceeding 320000 lux at around 09.00 am.…”

Abstract. Daud M, Bustam BM, Arifin B. 2019. A comparative study of carbon dioxide absorption capacity of seven urban forest plant species of Banda Aceh, Indonesia. Biodiversitas 20: 3372-3379. Global warming has been a major issue affecting all parts of the world in recent years. One method of reducing the impact of global warming is through supporting the green open space. The city government of Banda Aceh, Indonesia has targetted as much as 30% of its area to the formation of green open space. The BNI urban forest is one example of the green open spaces in Banda Aceh. This research was conducted to know the carbon dioxide absorption capacity in seven selected tree species found in the urban forest. The method that has been applied was the explorative survey method with purposive sampling. The data were analyzed using linear regression and correlation analysis. The results showed that the highest ability of carbon dioxide absorption per leaf per hour was found in the Terminalia catappa (0.511 g/leaf/hour) and the lowest was found in the Calophyllum inophyllum (0.056 g/leaf/hour). While the highest carbon dioxide absorption per tree per hour was found in Pterocarpus indicus (4,642,293 g/tree/hour) and the lowest was found in Calophyllum inophyllum (162,640 g/tree/hour). The results of linear regression analysis showed that there was no strong correlation and no significant effect between leaf surface area and mass of carbohydrate, to capacity of carbon dioxide absorption in urban forest plants.

“…Jumlah radiasi matahari yang diterima bumi bergantung pada keadaan atmosfer, jarak bumi dari matahari, intensitas dari radiasi matahari dan lamanya penyinaran matahari (Sari et al, 2015). Perlu pengukuran khusus untuk mengetahui jumlah intensitas cahaya dalam satuan W/m 2 sebagai sumber energi panel surya menggunakan Pyranometer.…”

Pembangkit listrik Photovoltaic (PV) dianggap sebagai cara yang efektif dalam mengurangi konsumsi bahan bakar fosil tetapi kekurangannya adalah permukaan yang terlalu panas dapat mengurangi kinerja panel. Pada penelitian ini, PV panel telah dikombinasikan dengan metode pendingin dari Ground Heat Exchanger (GHE) dengan variasi kecepatan udara GHE sebesar 1, 2, dan 3 m/s untuk mengetahui performa PV Panel. Performa panel meliputi: temperatur permukaan panel performa GHE yang diwakilkan dengan energi kalor udara (J) yang dibuang ke dalam tanah serta kondisi cuaca pada saat penelitian. Hasil pengamatan menunjukkan bahwa Intensitas radiasi matahari terjadi fluktuatif akibat dari anomali cuaca, tingginya intensitas radiasi matahari berkisar 1000-1250,50 W/m2 diikuti oleh kenaikan temperatur lingkungan 30-33,80C. Energi kalor udara yang dibuang ke tanah tertinggi variasi kecepatan udara, energi kalor udara yang dibuang sebesar 444,974 J pada pukul 11.00. Semakin cepat kecepatan udara GHE maka dapat meningkatkan energi kalor udara yang dibuang ke tanah. Temperatur permukaan panel terendah terjadi pada variasi kecepatan pada kecepatan udara 3 m/s yaitu 25,6C. Semakin dalam posisi GHE dan semakin cepat kecepatan udara GHE dapat meningkatkan efisiensi dari panel surya.Kata kunci: Pendingin Panel Surya, variasi kedalaman, Temperatur panel

“…Lamanya penyinaran matahari tidak sama setiap harinya [12]. Variasi durasi penyinaran matahari diukur selama 5 hari [13]. Panel fotovoltaik yang disusun dalam kisi-kisi pada interval tertentu, dan dengan peningkatan lebar jarak (dari 0 -20 cm), transmisi cahaya meningkat secara bertahap (dari 0 hingga 90%) [14].…”

One of the problems of laying solar panels and attenuation will affect the output power of the solar panels. Several other studies have been carried out with different heights and the addition of attenuation will increase the output power of solar panels. This research was conducted using experimental methods for 6 designs that have been planned. Design 1 solar panel without height and without attenuation, design 2 solar panels without height using attenuation, design 3 solar panels with a height of 10 m and without attenuation, design 4 solar panels with a height of 10 m and use attenuation, design 5 solar panels with a height of 75 m without using attenuation and design 6 solar panels with a height of 75 m and using attenuation. This study aims to determine the effect of changing the height of the solar panels and adding attenuation to see how much power the solar panels produce when they are sunny. Measurement of voltage (Voc) and current (Isc) was carried out for 5 days. The results showed that the highest average output power of solar panels was in design 6 of 45.16 W, while the lowest average output power of solar panels was in design 1 of 41.43 W. The output power of solar panels in design 6 is 8 .3% more than design 1.
