Abstract

A coil winding machine for water pumps using a monitoring system is a development of conventional winding tools. In regular coil winding tools, the coil winding process is done manually by rotating the handle as many times as the desired number of turns. The conventional winding tools have problems consisting of inconsistent working speed and operator-dependent winding continuity. Undesirable windings can occur with conventional winding tools, and the winding process requires close supervision. Therefore, the automatic coil winding machine was developed to optimize the coil winding process. The machine utilizes a DC motor to rotate the coil rolls, replacing the conventional roller handle function. This machining method uses an optocoupler sensor. The sensor serves to identify and evaluate the rotation of the roller. In addition, the ATmega8 microcontroller was applied to develop a system that can work automatically. Data collection involves varying the number of wire turns and the wire diameter dimension. The variation is necessary because the number of windings and wire diameter affect pump efficiency and performance. The data testing showed a machine accuracy rate of 98%, with a maximum difference of 1 coil winding in the results. This data confirms that the coil winding machine meets the tool's accuracy standards.

Abstract

Research has focused on a wind turbine system with a vertical-axis Darrieus design with a capacity of 15 watts, serving as an aerator for aeration or adding air to water. The Darrieus turbine, made of aluminium with three corners and a modified NACA 0018 model optimized to work at low wind speeds of 2 m/s, effectively powers a 4-watt DC aerator. Generator voltage readings show a minimum value of 2 volts at a wind speed of 1 m/s and a maximum value of 12.8 volts at a wind speed of 6.2 m/s. The calculated power coefficient is 0.3. Charging the accumulator with a 12 volts/12 Ah takes 23 hours with a generator voltage of 13 volts at a wind speed of 6 m/s. This research reflects Indonesia's progress in optimizing wind energy for sustainable power generation.

Abstract

Ujungmanik Village, Kawunganten District, Cilacap Regency, which is in the Segara Anakan Cilacap area, has natural resources, especially eucalyptus plants, which have the potential to develop the economy of the village community. The biggest problem faced by LMDH Dadi Makmur as a unit that manages the eucalyptus oil business is that after the production of eucalyptus oil distillation, it will produce residual waste from cajuput oil twigs and leaves with quite a large volume and only be left piled up around the yard where the distillery is, causing area storage of essential oil raw materials is narrow and also takes a long time to become organic fertilizer. The innovation offered through this community service activity is implementing a briquette printing machine from eucalyptus oil refining waste which is energy efficient and based on solar panels. The results of the dedication show that the eucalyptus oil waste processing activity in addition to reducing environmental pollution also produces biomass briquettes that can be utilized by the residents of Ujungmanik Village as a leading economic product of Ujungmanik Village.  Keyword: Cajuput oil, briquette, solar panels

Abstract

Metal Matrix Composite is one of the metal composites that utilize aluminum alloy as a matrix in its fabrication. MMC has better specifications than the conventional materials it forms because it is light, ductile, with better hardness properties. The aluminum alloy as the matrix in this study has good mechanical properties but relatively low hardness values, especially type 2xxx aluminum containing Al-Cu or duralumin. By adding silicon carbide (SiC) ceramic content which acts as a filler in the manufacture of MMC it aims to increase the hardness value through a strengthening mechanism by analyzing the distribution of filler particles to the matrix. Using the sintering method with temperature variations that affect the mechanical properties of MMC. From the tests carried out the MMC specimens experienced an increase of 7.06% with the highest hardness value at 300oC sintering temperature of 71.6 HRB. With a SiC content of 14.42% Wt. Then it was observed using a Scanning Electron Microscope (SEM) that the distribution of SiC particles experienced an even distribution and bonded to the aluminum matrix thereby reducing porosity and increasing the hardness value of the MMC material.

Abstract

This study investigates the application of the Internet of Things (IoT) for wireless control and monitoring of a 3-phase electric motor using a smartphone. The system integrates PZEM-004T, DS18B20, and Hall Effect sensors to collect data on voltage, current, temperature, and rotational speed using the NodeMCU ESP8266 microcontroller. Measurements are displayed on an LCD and transmitted to the Blynk server for smartphone access. A comparative method evaluates the accuracy of sensor readings against standard measuring instruments. Results obtained an average percentage error of 0.5% for the R phase voltage, 0.2% for the S phase, and 0.1% for the T phase. Current measurements reveal errors of 5% for the R phase, 10.3% for the S phase, and 11.7% for the T phase. The control system’s performance varies with internet speed, with an average delay of 0.99 seconds on a 4G network and 2.51 seconds on 3G. Additionally, the study evaluates three protection mechanisms, demonstrating that the motor stops within 4.03 seconds in the event of a phase failure, while overcurrent and overheating protections activate within 8.47 seconds and 3.64 seconds, respectively. Overall, the findings affirm the viability of IoT in motor monitoring and control, emphasizing accuracy and response times under varying conditions.

Abstract

Electrical energy is one of the most important energies in everyday life so high-voltage electrical equipment has a vital role in maintaining the reliability of electric power distribution. The corona effect is caused by insulation failure in high-rise equipment which results in disrupted electrical power distribution. The purpose of this research activity is to produce a multi-sensor tool to test the condition of equipment in distribution network booths that have experienced the corona phenomenon. The input data from several sensors used, such as the ozone sensor, will detect ozone gas exposed in the 20kv chamber, detection of ultraviolet light by the UV sensor module, and detection of sound frequency from the hissing of equipment through the microphone sensor experiencing corona will be processed by the Microcontroller and if the value is detected exceeds the reference value that has been set, the output in the form of an LCD will display a corona symptom warning message and instruct the buzzer alarm to sound. The results showed that the prototype of the corona detector was able to identify ozone levels with a maximum value of 21.88 ppb, the largest UV index value of 336, and a maximum hissing frequency of 157 dB in distribution cubicles that experienced the corona effect.

Abstract

Rice is a staple food in Indonesia and globally, but its production is threatened by pests such as the brown planthopper. Conventional pest control methods, including pesticides and traditional techniques, often prove ineffective and have negative environmental impacts. Light traps have been explored as an alternative due to the brown planthopper's phototactic behavior, yet existing designs lack efficiency in capturing pests. This study presents an IoT-based solar-powered pest control system that integrates light as an attractant and an electric trap for effective pest elimination. The system features real-time monitoring of voltage, current, and light intensity using an LCD display, powered by a 35 Wp solar panel and managed through an Arduino Uno microcontroller. Experimental results show that brown planthoppers are most attracted to an LED light with an intensity of 780 lux, operating at 11.5 V and 0.97 A. The system consumes 112.52 Wh, with a full battery charge requiring approximately 6 hours and 7 minutes. These findings highlight the potential of a sustainable, energy-efficient solution for pest control in rice agriculture.

The dedication results show that the eucalyptus oil waste processing activity and reducing environmental pollution also produce biomass briquettes that the residents of Banjarwaru Village can utilize as a leading economic product of Banjarwaru Village. The test data of the briquette making machine shows that the output voltage from the inverter produces an AC voltage with a value of 216 - 221 V, so that it can rotate the AC motor with a rotation of 800 - 1400 rpm.
