Abstract

The utilization of wind energy as one of the renewable energy sources in Indonesia is still limited. This is due to Indonesia's large wind potential, but it is at low speeds. One modification of wind turbines to overcome this problem is by using inverse taper and taper blades. Inverse taper blades have a chord distribution that increases from root to tip while taper blades have a chord distribution that decreases from root to tip. This research conducts the design and construction of inverse taper and taper blades on small-scale wind turbines using NACA 6412 airfoil type, then tested in the field and obtained the performance of each blade. The design was carried out using blade element momentum theory to obtain the blade geometry shape and perform performance analysis of each type of blade. Based on the simulation results obtained from QBlade, it shows that the inverse taper blade performance has a maximum Cp of 0.52 while the taper blade has a maximum Cp of 0.41. The power graph from field testing results shows that inverse taper blades provide good power generation at low wind speeds compared to taper blades. The inverse taper blade has a cut-in speed of 1.2 m/s and the best power production occurs at speeds of 1-4 m/s.

Abstract

The dehydration of Moringa Oleifera leaves is crucial to preserving their high nutritional value and extending shelf life for use in food and pharmaceutical applications. Traditional drying methods often result in nutrient degradation and lack precise environmental control. This study presents the design and implementation of an internet of things (IoT)- enabled electrical dryer system controlled by a microcontroller for the efficient dehydration of Moringa leaves. The system integrates temperature and humidity sensors, an Arduino Mega microcontroller, and a web-based interface for real-time monitoring and control. The electrical dryer maintains optimal drying conditions, significantly reducing moisture content while preserving essential nutrients. Data is logged and visualized through IoT connectivity, allowing for remote access and performance analysis. The dehydration of Moringa leaves requires approximately one kg of electricity for batteries in dual-energy dryers, which are based on microcontrollers and the IoT. The results demonstrate that the proposed system offers a reliable, energy-efficient, and scalable solution for the controlled dehydration of Moringa leaves, with potential applications in smart agriculture and postharvest processing. The excellent drying time is achieved in a greenhouse dryer, which maintains a temperature of 45 °C within the drying chamber, resulting in a median drying time of 6 hours. The standard moisture percentage of clean and dry Moringa leaves is measured at 18.5% (wb) and 8% (wb), respectively.

Abstract

UD. XYZ is a Small and Medium Enterprise (SME) focused on bread production. During its production process, it encounters various challenges such as changes in raw material prices, problems in the dough fermentation process, delays in supplier deliveries, and an expiry rate of 8-18% per month. Specifically, a two-part House of Risk (HOR) model and a Supply Chain Operations Reference (SCOR) model are used. First, the SCOR model is used to map the processes in the bakery product supply chain. This data is then loaded into the first stage of the HOR. The next step is to determine the ARP value after evaluating the severity and frequency of incidents. Strategies to manage or mitigate risks are developed using the HOR in the second stage. Twenty risk events and nineteen risk agents were identified at UD. XYZ, with ten priority risk agents identified using a Pareto diagram and mitigation techniques developed. To reduce the likelihood of risk agents appearing in the organization, the second stage of the HOR includes sixteen suggested management tactics.

Abstract

This study evaluates the performance of Pure Sine Wave (PSW) and Modified Sine Wave (MSW) inverters within small-scale off-grid solar power generation systems. The assessment was conducted utilizing a 160 Wp monocrystalline solar panel, a 10 A solar charge controller (SCC), a 12.8 V–100 Ah lithium iron phosphate (LiFePO₄) battery, along with both 500 W PSW and MSW inverters, across varying panel tilt angles ranging from 45°-165°. The findings indicated that the PSW inverter delivered a more consistent output voltage between 221 and 222 V, exhibiting minimal fluctuation of ±1 V and low harmonic distortion at 2.5%. The MSW inverter produced an output voltage between 222 and 225.5 V, characterized by greater variability and higher harmonic distortion under both light and heavy load conditions. The analysis of the solar photovoltaic (PV) system provides critical insights into the performance differences between the two inverter types. Notably, the results related to tilt angle are not merely supplementary; they serve as indicators of varying irradiance conditions, enabling a more comprehensive evaluation of inverter performance concerning fluctuations in input power levels. Both PSW and MSW inverters achieved an efficiency rating of 85%, ensuring stable and smooth outputs. However, with regard to long-term reliability, the PSW inverter significantly surpasses its counterpart, rendering it a more appropriate choice for permanent solar PV installations. As the results, the PSW inverter is particularly suited for sensitive loads that demand high power quality, while the MSW inverter remains viable for less demanding applications when the cost is considered.

Abstract

Electrical power is used not only for lighting but also for devices that can facilitate daily activities, such as washing machines, where this device drives a device called an electric motor. Electric machines are widely used in various places to help humans complete their work. Electric machines have many types and uses according to their type. The use of an electric machine is generally very frequent, therefore the possibility of damage due to age and condition is the main cause. To extend the life of an electric machine, maintenance is necessary, and if damage occurs, it can usually be repaired so that the cost of use is cheaper when compared to buying a new electric machine as a replacement. The most common damage is in the windings of the electric machine. The windings are long conductor wires wrapped around the stator (the stationary part). This winding is where the rotating electric field will be generated which will affect the conductors in the rotor (the rotating part) so that it can rotate. This winding is the most important part of an electric machine or motor. When the electricity supply is disrupted, some people use a temporary power generator called a generator set (a generator that is driven by a combustion engine or what is called a genset). These two devices, motors and generators, are known as electrical machines. Therefore, the community service team felt the need to conduct training for several interested community members. This training, called Introduction to Electrical Machines, was conducted. By utilizing the skilled workforce already available within the Electrical and Computer Engineering Department, Faculty of Engineering, Unsyiah, including lecturers, students, and the laboratory, the training is expected to increase the number of skilled personnel in electrical machine maintenance and repair. This will, in turn, increase budget savings in the use of electric motors within the community.

Abstract

Electric motors are widely used in various places to assist human work. Their intensive use makes damage due to age and operating conditions a common occurrence. The most frequent damage occurs in the motor windings, the most critical part that generates a rotating magnetic field. Repairing this damage requires rewinding the coils with high precision, as errors can cause the motor to malfunction. To extend the motor's service life and reduce repair costs, skilled personnel are needed in the community who can perform electric motor maintenance and repair. Therefore, the community service team conducted training on motor winding rewinding for interested community members. This training utilized experts from the Department of Electrical and Computer Engineering, Faculty of Engineering, Syiah Kuala University, including lecturers, students, and laboratory staff. This activity aims to increase the number of skilled workers in electric motor maintenance and repair, particularly in rewinding coils, so that electric motors can function properly again and maintenance cost savings can be improved in the community. The results achieved showed a noticeable improvement in participants' understanding after the training, and participants were able to perform the motor winding rewinding practice under guidance.
