Abstract

Air bersih semakin langka di seluruh dunia akibat polusi, perubahan iklim, dan pertumbuhan penduduk. Salah satu solusi adalah desalinasi air laut dengan metode solar still yang ramah lingkungan. Penelitian ini fokus pada forced flow solar still yang memanfaatkan aliran udara untuk meningkatkan laju penguapan dan produktivitas air tawar. Temperatur air mempengaruhi kinerja solar still; semakin tinggi temperatur air dan kecepatan aliran udara di dalam solar still, maka penguapannya juga akan meningkat. Penelitian ini bertujuan menentukan laju penguapan air laut dalam forced flow solar still. Perangkat desalinasi ini menggunakan kondensor dan pengukuran parameter seperti temperatur dan kecepatan aliran udara, dengan data penguapan dikumpulkan setiap 15 menit selama 2 hari. Hasil penelitian menunjukkan bahwa forced flow solar still efektif meningkatkan laju penguapan. Temuan ini dapat membantu meningkatkan efisiensi desalinasi menggunakan solar still dengan mempertimbangkan faktor iklim lokal.

Abstract

Renewable energy is renewable and non-polluting energy. One of the new renewable energies is wind, Indonesia itself has an average wind speed of around 3-6 m/s. Wind turbines are tools used to convert wind energy into electrical energy, small-scale wind turbines are wind turbines that have a maximum output power of no more than 500 watts. There are several components in a wind turbine such as generators, fins, controllers, data loggers, batteries and blades. One of the important components in a wind turbine is the blade because the blade is the component that is directly facing the wind. If what is designed is an inverse taper type blade which has a widening shape towards the end by applying the cross sectional shape of the NACA 6412 airfoil. The performance test of the blade is carried out for 3 days with the highest wind speed data acquisition of 8.12 m/s at 13:00 noon and electric power the highest obtained was 136.53 watts at 13:00 noon

Abstract

Wind power plant is a new renewable energy, power plant that utilizes wind turbine rotation to convert wind energy into electrical energy. One of the modifications to the wind turbine that is done is to vary the number of blades. The results of variations in the number of blades are expected to increase the efficiency of wind turbines at certain speeds. In this research, we will vary the number of blades 3, 4 and 5 with an AG 12 airfoil assisted by the Q-Blade application for simulation and find out the results of calculations in graphical form. Variations are made at a minimum wind speed of 2 m/s to a maximum wind speed of 12 m/s. With a planned power coating of 500 watts assuming a turbine rotation of 400 rpm, using a horizontal axis wind turbine (TASH). With a minimum wind speed of 2 m/s, the variations in the number of blades 3, 4 and 5 have not been able to generate power because the turbine rotation factor is too fast at low wind speeds, while at a maximum wind speed of 12 m/s the power generated by the three blade variations 3, 4, and 5 are able to meet the planned power capacity of 500 watts. The highest efficiency is obtained in the variation of blade 4 with 0.453 at wind speed 8 with a power of 300.37 watts, then 0.37 in the variation of 3 blades at a speed of 7 m/s with a power of 164.28 watts, in the variation of blade 5 the highest efficiency is in the figure is 0.29 at a wind speed of 10 m/s with a power of 409.14 watts.

Abstract

The growing demand for air conditioning systems has driven research into alternative applications, such as seawater desalination. This study evaluates the performance of a modified window air conditioner (WAC) integrated with a vortex generator for desalination. Experiments were conducted using R410A refrigerant under four conditions: closed container (CC), without vortex (WV), connected vortex (CV), and separated vortex (SV). Seawater was heated via the condenser to 55–60°C, controlled by a thermostat, and data was collected every five minutes over eight hours. The thermodynamic properties of R410A were analyzed using Refprop software to determine refrigeration effect (RE), compression work (CW), and coefficient of performance (COP). Results indicate that the SV configuration achieved the highest evaporation rate (5.01 kg) but led to a lower COP (3.91) due to increased condenser temperature and compressor workload. Conversely, CC yielded the highest COP (5.08) by stabilizing the evaporator air temperature and reducing compressor effort. These findings suggest that vortex generators enhance evaporation rates but reduce system efficiency. Further research is needed to optimize vortex generator configurations to improve desalination efficiency while minimizing COP reduction.

Abstract

The utilization of water resources as renewable energy through waterwheels presents an environmentally friendly alternative, however, its efficiency requires improvement through technological modification. This research investigates two design modifications: a 45° Angle Cap (AC) and a Water-Filled Angle Cap (WFAC), in comparison with a waterwheel without a Cap (WC). Experiments were conducted at discharges from 1 to 10 m³/h with a constant torque load of 0.05 N-m. The highest efficiency of 57.08% was achieved in the AC 45° configuration at 1 m³/h, generating 1.09 watts of power, while the WFAC 45° yielded the highest power output of 2.88 watts at 10 m³/h with an efficiency of 14.50%. Although increasing discharge generally led to higher power input, it was accompanied by a decrease in efficiency across all configurations. Among all three variations, WFAC 45° demonstrated superior performance at higher discharges, indicating its potential for enhancing the power and efficiency of overshot waterwheels.

Abstract

Reduction of cylinder surface resistance can be accomplished by modifying roughness. The surface roughness structure is one of the important parameters which greatly affects the flow of fluid through the cylinder surface. Fluid flow forms a vortex flow pattern with certain characteristics. Therefore, this study aims to analyze the characteristics and effects of fluid flow through the rough surface of the outer wall of the pipe with visualization using Particle Image Velocity (PIV). This research was conducted experimentally at the Faculty of Engineering, UHAMKA. The pipe surface roughness values varied were 0.648 µm and 1.699 µm. The length of the pipe used is 20 cm with a diameter of 2 inches. Measurements are made from the center of the pipe to a distance of 0.16 m. The results show that the surface roughness of the cylinder pipe affects the fluid flow characteristics where the formation of eddies is caused by the addition of the roughness value. The rougher the pipe surface is, the farther the vortex formation will be. The vortex formation closest to the pipe is a pipe with a roughness value of 0.648 µm at a distance of 0.04 m.

Method: This investigation implements a mixed-methods approach. Quantitative data was gathered using pre- and post-training evaluations to assess the enhancement of participants' knowledge and skills. Qualitative data was acquired via interviews and observations to elucidate the individuals' experiences and perceptions. The data underwent analysis by descriptive statistics and thematic analysis. Practical Applications: The results of this study have practical implications for the tourism industry as a whole and for the local community of Pulau Pari. The outputs of the training program can guide the creation of analogous programs in other locations, fostering the implementation of renewable energy and sustainable practices in edutourism. The findings may also assist policymakers and tourist stakeholders in incorporating solar cell implementation into their strategy for sustainable tourism development. Conclusion: The study's results demonstrate that the training program on solar cell application for enhancing edutourism in Pari Island has successfully improved participants' knowledge and abilities in renewable energy. The program can enhance the island's sustainable development by diminishing reliance on traditional energy sources and fostering eco-friendly tourism habits. The findings highlight the importance of integrating renewable energy education and training into community-based tourism programs to promote sustainability and resilience against global environmental concerns.
