Indonesia holds the third position in global coffee bean supply, with a 3.3% increase in demand in 2021 according to ICO data. In line with ICO Resolution 407, coffee bean quality must be high, indicated by a 12.5% moisture content through drying processes. Mechanical drying is faster than traditional methods, thus becoming the focus of this research. This study implements an IoT-based monitoring system for coffee bean drying equipment. The aim is to create and implement a monitoring system for temperature (0°C - 70°C) and electrical energy consumption (kWh) in coffee bean drying, displayed on the ThingSpeak dashboard. Test results show that the temperature monitoring system using DHT22 sensors at the inlet and outlet of the rotary dryer tube has an average error of 2.1%. The energy monitoring system using PZEM-004T has a 0% energy measurement error. These results indicate a reliable monitoring system that enables remote monitoring via the internet. Furthermore, the study tests manual (on/off) and fuzzy logic control methods to achieve 12% moisture content in coffee beans. The fuzzy logic control method demonstrates better temperature stability and 11.2% cost savings in operational expenses. This research benefits coffee farmers by facilitating efficient monitoring of the bean drying process, and recommends the use of the fuzzy logic control method for stable temperature and lower operational costs.

Onthok yuyu is a traditional cake included in the dry cake category and is made from sticky rice flour. Onthok yuyu is also known as Onthok worm, this is because the shape of the cake resembles a mound dug up by worms or yuyu (Javanese: crab). The traditional Onthok yuyu cake outside Java is more often known as coconut root cake, because its shape resembles the roots of a coconut tree piled up on the ground. The forming process is carried out before the dry cake processing process, usually the raw material is flour mixed with liquid (water, butter) etc. to become a dough. Forming is done on the dough, then processing is carried out by frying or baking. The process of forming or molding food products on an industrial scale can be done using extrusion or molding processes. If an elongated product is desired, the forming process is extrusion, namely using an extruder machine by installing output holes whose shape and size are adjusted to the cross-section of the desired food product. If a certain shape is desired, the dough is extruded and then continued with forming or molding. Basically, molding can be done carried out by two methods. Efforts to empower Micro, Small and Medium Enterprises (MSMEs) require an empowerment model that includes improving existing MSMEs so that they are more advanced so they can strictly competent in free market competition.

In new renewable energy, the abundant potential of solar energy in Indonesia needs to be utilized effectively, especially in vocational canteens for the purposes of lights and fans. This research aims to design and build an off-grid solar power generation system and Node-Red-based monitoring at the Canteen. The research method used is experimentation through direct observation at the vocational canteen. The tests carried out are the system of SPGS which includes voltage, current, and power and testing monitoring by system sensors and temperature sensors for 5 hours per day in two days. The results obtained are the voltage in the system both panel voltage, AC voltage, and battery voltage are stable and do not exceed the specifications of solar panels. However, the current has increased and decreased although not too drastically and the battery has only decreased by 10%. This is due to the influence of the weather during testing and is not affected by the load power because it does not exceed specifications. In addition, the system sensor has an error of no more than 2% so it can be said that if this system functions optimally and as expected, it can be developed more to save energy.

Knee joint fractures caused after surgery or other activities that cause knee dysfunction require a rehabilitation process. Knee dysfunction means the knee joint cannot be bent/moved at the desired angle. Because the function of the knee is so important in relation to human activities, it is necessary to immediately carry out rehabilitation measures for a perfect return. Rehabilitation in this case can be done with weight training. In this research, loading for rehabilitation will be designed using load cell-based electronic engineering for the desired load, because the equipment used so far works manually.The research began with inventorying component requirements, designing the circuit, compiling a process algorithm, functional testing, calibration and data collection. The research data is a function of weight on movement, in this case motorbikes. The output of the research is a control circuit prototype to regulate load-based motor movement.The equipment specifications are produced with a loading capacity limit of 5 kg with a change step of 250 grams.

Currently, solar panels are widely used in homes, offices, and buildings. Solar energy is converted into electrical energy by solar panels. The surface of solar panels determines how efficient they are; if the surface is dirty, the efficiency of solar panels will decrease. Therefore, they must be cleaned to maintain their effectiveness. Cleaning solar panels is one of the tasks that can be performed by an autonomous robot, which can move without the need for human control or remote control usage. To make the robot move autonomously, a camera is used to capture images of solar panels so that the robot can move on its own. The images captured by the camera will then be processed using a classic line detection algorithm (Hough line transform) to estimate the direction, in the form of the angle (theta), of the robot relative to the solar panel based on the lines detected by the algorithm. The direction of the robot relative to the solar panel determines the robot's future movement. The algorithm used (Hough line transform) has been able to estimate the direction of the robot quite well with a relatively fast processing time. Thus, it can be concluded that this research successfully determines the direction based on the available images

The use of electrical energy plays a vital role in supporting the continuity of production processes in industrial environments. One critical area that heavily relies on electrical power supply is in the planning of installing a capacitor bank with a detuned reactor. The primary objective of this planning is to enhance the power factor (cos φ) from 60% to 85.2% during full-load operations and up to 94% when operating as per demand simulations. The evaluation of power quality from the implementation of the Capacitor with Detuned Reactor is conducted through simulations using ETAP 12.6.0 software.The simulation results from ETAP 12.6.0 produce comparative graphs between buses equipped with the Capacitor with Detuned Reactor and buses without it, both during full-load operational conditions and when only operating in simulations. The information derived from the simulation provides a deeper insight into the impact of installing the capacitor with detuned reactor on power factor and power quality within this industrial environment. With this understanding, further steps can be taken to optimize the electrical power system within the industrial setting.

Many people in Indonesia keep freshwater ornamental fish, including guppy fish (Poecilia reticulata), green growth fish (Gyrinocheilus aymonieri), neon tetra fish (Paracheirodon innesi). Neon tetra fish are popular because of their distinctive striking and bright body lines, while guppy fish are kept because of their ease of care and beautiful color variations, especially in male guppies. Guppy fish can grow well at temperatures of 22°C - 27°C and pH 6.5-7.2. Because managers are busy, this becomes an obstacle in fish cultivation, because the water quality that determines fish development becomes unstable. The results of the PLTS output test for 7 days 7 hours per day from 09.00 – 15.00 WIB can charge the battery with an average voltage of 13.89 V and an average current of 1.2 A and an average power of 14.15 W and can run for 24 hours. O'clock. Testing the battery for 7 days and 7 hours from 09.00 – 15.00 WIB can meet power needs for 24 hours with an average battery voltage of 13.36 V and an average current of 0.71 A. Meanwhile, the test results for the servo motor with a feed weight of 2, 45 grams and a servo motor delay of 2 seconds. Testing the pH of the water using a pH pump showed a change from the initial value of 8.06 to 6.91 and was measured with the PH4502C sensor. Tests without a PH pump showed an increase in changes from the initial pH value of 7.76 to 8.05.

The central government has established the National Energy Policy (KEN) to increase the utilization of renewable energy sources (EBT) by around 23% by 2025 and 31% by 2050. In an effort to support the government's program, researchers have developed a Thermoelectric Generator (TEG) as an alternative power supply to replace the energy source from PT PLN for electrical equipment used in the green bean germination process such as lights, fans, and water pumps. This prototype consists of two chambers: a combustion chamber that generates electrical energy and a control room for the germination process. These two areas are separated to ensure that the control device and germination process are not affected by the heat from combustion. The main components of this prototype include ten TEG units with a maximum power of 5.2 W, a 33 Ah battery, an 8A Buck-boost converter, a 3A Buck converter, a 6W Full Spectrum LED, four DC fans, and a DC pump. The TEG functions effectively as the germination process proceeds smoothly.

Single phase induction motors are one of the most frequently used types of motors because of their economical, sturdy, simple and easy maintenance advantages. One application is for electric vehicles. When single phase induction motors are applied to electric vehicles there are problems related to torque regulation based on vehicle operating conditions where when operating on light road conditions the torque produced by the motor remains high. In this research, a single-phase induction motor was made to have the same proportion of torque produced by the main coil and auxiliary coil or a 1kW 1000 rpm symmetrical two-phase induction motor. The type of winding applied to the stator is divided screws with the main and auxiliary coils each occupying 18 stator slots, 45 conductors per slots,, with a conductor diameter of 1.2 mm. As a phase shifter at start and operation so that they differ by 90°, a capacitance of 505.51 µF is used. As a result of the winding modification, the induction motor parameter values for each stator winding are the same. So the starting torque of the main and auxiliary coils is 3.89 Nm and 3.88 Nm respectively and the nominal torque produced by the main and auxiliary coils is 4.28 Nm and 4.29 Nm respectively.

So the starting torque of the main and auxiliary coils is 3.89 Nm and 3.88 Nm respectively and the nominal torque produced by the main and auxiliary coils is 4.28 Nm and 4.29 Nm respectively.","PeriodicalId":476257,"journal":{"name":"Elposys: Jurnal Sistem Kelistrikan","volume":"1983 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140416771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Controlling temperature is crucial because it is the most significant factor in the distillation process. Temperature instability is a result of manual and traditional control, and several errors may occur. Therefore, the low quality of the product that is produced during the distillation process has an additional effect. In order to effectively control or manage the system, an automatic temperature control system is designed using an electronic controller with a closed system control mode that not only delivers setpoint values but also feedback.The procedure of distillation that is being employed involves combining two different kinds of solutions: water and ethanol, which has a boiling point of 78°C.Thermocouple sensors are used to monitor temperature, and PLCs with PID control are used to process the temperature data that are obtained. For plant supervision, control, and data collecting, a SCADA is necessary. A number of tests have been conducted, including near loops with and without PID that are SCADA-monitored. The temperature stability response is then examined by analyzing the outcomes of multiple tests that have been conducted. Values of Kp = 5188, Ti = 182, and Td = 457 were found by using the Ziegler Nichols method to the temperature control of the distillation equipment. Furthermore, the steady state error was no more than 1% and the overshoot characteristics were only 2.5%, according to the system response graph.. From the Ziegler Nichols PID control parameters, it shows a good system response and produces ethanol distillation results with a concentration of 88%.
