Abstract

Sunlight can be harnessed as a clean and renewable energy source using solar cells and the photovoltaic process. However, relying on direct sunlight exposure can increase solar cell temperatures and negatively impact performance. This research aims to maintain cell efficiency by exploring the effectiveness of spraying coolant media on the bottom surface of panels through three timed intervals (10, 20, and 30 minutes) using three different media (A, B, and C). Each spray application lasts for 1 minute. Analyzing the test results with Minitab18 software with full factorial design will identify the most effective treatment for maintaining performance. Based on the results of the experimental test, coolant A with a 10-minute delay spraying time has a maximum power of 52.89 Watts, a temperature of 48oC, and an efficiency of 5.69%. Response Optimization using Design of Experiment (DOE) Full Factorial shows an optimal response with coolant A and a 10-minute delay spraying time with the lowest temperature at 49.3oC, maximum output power at 46.87 Watts, and efficiency at 5.61%. Moreover, Tukey Krammer test result provides an information about 10-minute delay spraying time has a better performance to reduce the PV panel temperature compared to 30-minute delay spraying time by 3.94 oC.

Abstract

This research discusses the method of making distribution pipes using the Submerged Arc Welding (SAW) welding process, especially for pipes with spiral connections. The material used is API 5L X65. SAW pipes with spiral joints are more commonly used for low-pressure piping systems. However, in certain cases, the production of SAW pipes for Sour Service distribution requires special treatment. Sour Service pipes have a high level of corrosion and residual stress, so Post Weld Heat Treatment (PWHT) is required to prevent Hydrogen Induced Cracking (HIC). HIC occurs due to the absorption and accumulation of hydrogen gas in the metal, causing the formation and growth of cracks, which is also influenced by residual stress. PWHT is applied to reduce residual stress to reduce the risk of corrosion. PWHT is a process to change the structure of the weld metal by heating the metal at a certain temperature and time. This research shows that variations in PWHT temperature produce an average residual stress that is not much different with less difference than 2%, In corrosion testing with the HIC method shows crack evidence but is still satisfactory NACE MR0175 criteria for pipe PWHT temperature variation conditions

Abstract

This study explores the optimization of bio-oil additives derived from the pyrolysis of Ulva lactuca algae, blended with RON 90 gasoline to enhance engine performance and reduce emissions. Addressing the urgent need for sustainable energy, the research focuses on a relatively unexplored area—using algae-derived bio-oils in gasoline engines. The study aimed to identify the optimal blend ratio of bio-oil and gasoline to improve engine metrics such as brake specific fuel consumption (BSFC), thermal efficiency, and volumetric efficiency, while minimizing emissions like CO, CO2, and NOx. Experiments were conducted with bio-oil blended at 5%, 10%, and 15% by volume with RON 90 gasoline in a single-cylinder gasoline engine. Results showed that increasing bio-oil concentration led to improved fuel efficiency and thermal efficiency, along with significant reductions in CO and HC emissions. However, NOx emissions presented a complex trend, increasing at lower bio-oil ratios but decreasing significantly at the highest concentration. These findings suggest that algae-derived bio-oil can effectively enhance gasoline engine performance and reduce environmental impact, offering a novel, sustainable alternative fuel option. The study underscores the importance of optimizing blend ratios to maximize benefits and manage emissions, contributing valuable insights to sustainable energy research.

Abstract

Alternative fuels such as Methanol-Butanol-Etanol (MBE) are worthy of development because of their optimal characteristics in SI engines. Selective government regulations on vehicle emissions require a shift to environmentally friendly innovative energy. Fuel-containing alcohol has been proven to reduce pollution levels in vehicles optimally. This research has explored MBE fuel mixtures with three variants through experimental methods. Variations MBE1, MBE2 and MBE3 were mixed with gasoline (RON-90) with capacities (5:2:1, 8:4:1, and 10:6:1)v/v when tested using a dyno test on an SI engine automatic type compression ratio 10:1 with a speed gap of 4000-9000rpm. During testing, torque and Mep experienced an optimal increase in MBE3 fuel of 10.78% and 10.55% compared to commercial fuel (RON-90). Engine power and thermal efficiency increased respectively by 10.03% and 10.69%. This condition is inversely proportional to SFC, which decreased by 21.05%. Furthermore, CO and HC exhaust emissions decreased by 12.12% and 4.60% respectively. This phenomenon shows that MBE fuel shows environmentally friendly performance and exhaust emissions for SI engines in daily activities.

Abstract

The application of Green Energy Technology through Passive Cooling System is the right solution. It aims to achieve energy savings and reduce CO2 emissions. This study focuses on the simulation of room conditions using the computational fluid method. The simulation aims to determine the effect of inlet and outlet configuration against the air condition in the room. The results presented in this simulation are the distribution of air temperature, air humidity, and air velocity. The variations used in the simulation are the air inlet and outlet positions, there are three configurations of air inlet and outlet positions. Variation 1: two inlets – one outlet, Variation 2: two inlets – two outlets, Variation 3: four inlets – three outlets. The results of the study show Variation 3 has the best design if cooling or heating equipment wants to be added, for example passive cooling in summer and a heater for cold weather. On other hand, Variation 1 is the most effective in maintaining the stability of humidity distribution and air velocity within the room. This configuration successfully creates optimal ventilation by generating efficient natural convection without significant fluctuations, achieved using two inlets and one active outlet
