Abstract

Renewable energy is the primary solution to future energy challenges. Horizontal-axis wind turbines (HAWTs) have great potential as a source of clean energy, especially in remote areas. This study aims to optimize the number of HAWT blades to increase the Coefficient of Power (Cp) through simulation and experimental methods. Optimization is done by modifying the angle of attack and the number of blades. Aerodynamic simulations using the QBLADE software were validated through laboratory experiments with small-scale prototypes. The study calculated the harvestable wind energy using the Betz limit (59%) and the Cp range from the previous study (35-45%). The turbine's efficiency is strongly influenced by the number of blades operating based on lift, with the glide ratio being an important parameter. The turbine blade was manufactured using NACA 0020 at the Mechanical Engineering workshop at Khairun University. Testing is carried out in the laboratory to measure the relationship between the number of blades, rotor rotation, and the generator's output power. This process accounts for mechanical, generator, and heat losses. The experimental data is validated by simulation and calculation to formulate the number of blade relationships as design recommendations. Based on analyses of the relationships among Cp, Cm, and TSR, and comparisons with previous studies, the number of wind turbine blades was shown to have a significant effect on aerodynamic efficiency, initial torque, and energy conversion performance. The 2-blade turbine is well-suited to strong winds due to its high efficiency at high TSRs, but it is less stable and has low starting torque. The 6-blade turbine excels at low TSR with ample initial torque, ideal for slow winds and mechanical applications, although its efficiency decreases at high TSR. 3-blade turbines offer the best compromise, making them a top choice in commercial systems.

Abstract

The purpose of the service program to redesign the installation of clean water pipelines is to provide new installations and repair clean water distribution pumps that are able to distribute clean water originating from river water in the Toniku Village area so that the water distribution system runs more evenly, both to the reservoir and to the reservoir. the community directly. The implementation of the activity begins with an initial survey to see the condition of the artificial wells and water reservoirs that will be repaired where there are artificial wells installed on the banks of the river. Repairs to the pipe installation are carried out by replacing 2 4-inch pipes so that the flow of water that will enter the reservoir does not suffer losses or is wasted. The initial design before the change was that there were many pipe connections that were installed from the pump to the reservoir so that the water flowing into the reservoir experienced a lot of loss or wasted a lot. From the results of the field review, the electrical capacity to drive the pump is not sufficient because the type of electrical cable connected is not suitable or unable to drive the two pumps. Errors also occur in the installation of capacitors where the pump has a 40 F capacitor type but the one installed is 50 F. For the problem of electricity capacity, the village government has tried to coordinate with PLN to replace the power cable. As for the capacitor problem, in this program we bought 2 capacitors to be replaced and installed. Keywords: Redesign, Water Pump, Reservoir, Drain Installation

Abstract

One of the implementations of PKM in 2021 carried out by the Mechanical Engineering study program is the manufacture of MCK, but the construction of MCK sanitation facilities to meet community needs has not been carried out due to the implementation limitations of the PKM program. Sanitation is one of the supporting programs in making MCK. The limited facilities and the behavior of people who use open spaces for defecating, bathing, and others will have an impact on aspects of public health. In this activity, a sanitation distribution from the existing MCK was built; hence water drainage and sewage of The  MCK are not polluted and will be maintained in terms of health. The problems of partners/communities in Takofi village are as follows; disposal of polluted MCK sanitation channels, lack of information about the importance of clean sanitation lines and supporting health aspects, and inadequate MCK sanitation sewer lines. Lack of knowledge of making MCK sanitation lines. The implementation of community service activities, repairing and building sanitation lanes for toilet disposal in Takofi village, Moti sub-district, was carried out for one day. Where the initial stage, the toilets were cleaned, which looked very dirty and were not functioning correctly. After cleaning, the next step is measuring and installing new installation pipes where the old network is no longer working correctly. This pipe installation is also related to another PKM program, namely repairing water wells as a water source to operate this MCK. Several students who participated in the PKM program also carried out this activity.Keywors; Sanitation, MCK, Desa Takofi

Abstract

Traditional drying of skipjack jerky is still widely used by MSMEs, but it is highly weather-dependent, prone to contamination, and produces less uniform quality. This research aims to design and test a prototype of an incandescent electric dryer that is simple to operate, provides controlled drying conditions, and is easy to use. The system developed is an insulated cabinet with stainless-steel mesh racks, incandescent light heaters, forced-air circulation, and temperature and humidity sensors, monitored during a 360-minute performance test with sample mass changes. The results showed that the drying chamber temperature remained stable at 43.9–49.3 °C, the relative humidity dropped from about 47% to ±30%, and the jerky mass decreased from ±917 g to ±353 g, with a final moisture content of about 30%. Compared to sun drying, electric dryers provide faster drying rates and more stable drying patterns, making the time to achieve the target moisture content and quality between batches more predictable. These findings show that the prototype is worthy of consideration as an alternative drying technology for seafood processing MSMEs and serves as a basis for further development to improve energy efficiency and product uniformity.
