Abstract

The aim of this research is to compare the performance of two differences tube configuration in solar hot water collector thermosiphon system of Serpentine-Parallel and Parallel-Serpentine. Not only the tubes configuration are not the same, but also the collector materials, such as hot water reservoir and heat absorber are differences. For example, fiberglass and stainless steel reservoirs are compared in terms of long-lasting heat isolation. Likewise, copper tubes configuration between serpentine-parallel and parallel-serpentine are shown in association with mass flow rates and times consume to heat the water within the tubes. The test results show that parallel-serpentine configuration has higher performance (around 50%) than that of serpentine-parallel (approximately 35%). It is possibly because of fluid velocity within the tube configuration.

Abstract

Fuel Oil Heater in Steam Power Plant (PLTU) at Tello Makassar, a heat exchanger type of heater that serves to heat the oil residue by using steam heat generated in the boiler. This study aimed to determine the effectiveness of water vapor to reduce the viscosity of oil residue that can be used as fuel by using fuel oil heater. Measurements were performed immediately when the temperature and pressure of water vapor and residual oil at the input and output unchanged (constant) for 1 hour. The results showed that the effectiveness is influenced by the amount of heat absorbed by the residual oil by 1726.083 W and the amount of heat released by the steam that is 1764.988 W with a value of 68.7% effectiveness.

Abstract

The TiO2 film is immersed in a graphite oxide solution, preparing it for thermal reduction, which converts the graphite oxide to reduced graphene oxide (rGO). This process produces rGO hybrid TiO2 photoanodes for dye-sensitized solar cells (DSSC). rGO in the TiO2 structure prevents electron recombination and improves overall efficiency. The main advantage of this method is its ability to prevent loss of rGO during the sintering process, which is a common problem with other methods. The study investigated heating temperatures ranging between 300˚C, 350˚C, 400˚C, 450˚C, and 500˚C to determine optimal conditions. The presence of rGO in the photoanode structure was confirmed via X-ray diffraction and Fourier transform infrared spectroscopy analysis. JV (current-voltage density) measurements of DSSC based on TiO2/rGO photoanode revealed that the highest photoelectric conversion efficiency (0.1923%) was achieved at 400˚C, much higher than other temperature variations. The findings demonstrate the effectiveness of a simple low-temperature thermal reduction process in producing graphene suitable for semiconductor applications in DSSC. The RGO produced through this method not only improves energy conversion efficiency but also outperforms traditional graphite electrodes. By optimizing the thermal reduction process and fine-tuning the heating conditions, this study advances the practical application of graphene-based materials in solar cell technology. This method overcomes the loss of rGO during sintering, ensuring its beneficial properties are retained. Overall, this study shows that low-temperature thermal reduction is an efficient technique to improve DSSC performance through the incorporation of reduced graphene oxide.

Abstract

DSSC adalah serangkaian perangkat yang menggunakan energi celah antara semikonduktor dan ikatannya dengan cluster di lapisan tipis untuk mengubah energi cahaya menjadi energi listrik. Struktur perangkat DSSC terdiri dari lima komponen yaitu kaca FTO, TiO2, pewarna, elektrolit dan karbon. Dari hasil penelitian dapat disimpulkan bahwa penambahan konsentrasi pewarna ekstrak daun bayam merah memberikan pengaruh terhadap peningkatan nilai arus, tegangan dan efisiensi DSSC. Nilai terendah terdapat pada konsentrasi zat warna 10gr dengan nilai arus 0,0000115 A, tegangan 0,2965 V dan efisiensi 0,009635%. Kemudian terjadi peningkatan dengan nilai arus sebesar 0,0000173 A, tegangan sebesar 0,3301 V, dan efisiensi sebesar 0,01692% pada konsentrasi zat warna 20gr. Pada konsentrasi zat warna 30gr mengalami peningkatan dengan nilai arus 0,0000215 A, tegangan 0,457 V dan efisiensi 0,030618%. Dan nilai tertinggi pada konsentrasi pewarna 40gr dengan nilai arus 0,0000241 A, tegangan 0,566 V dan efisiensi 0,042891%. Sedangkan pada konsentrasi zat warna 50gr terjadi penurunan dengan nilai arus sebesar 0,000023 A, tegangan sebesar 0,508 V dan efisiensi sebesar 0,035797%. DSSC is a series of devices that use the gap energy between semiconductors and their bonds with clusters in thin layers to convert light energy into electrical energy.
