clean water for their daily needs such as drinking, bathing, washing and so on. The community processing salty groundwater so that it can be drunk is still not efficient, because it is still done manually by cooking the salty groundwater using a pot and stove to produce water vapor, then it is collected using a glass or other container. The purpose of this research is to produce an automatic distillation device using an electric water heater to be able to detect water temperature, salt content, and water level with rocks using the Arduino Uno Microcontroller. The method used in this study uses data collection and system development (prototype) methods. The results of the research resulted in an automatic distillation device that can separate the salt content in salty groundwater so that the water is suitable for consumption and also produces salt that can be used by the community for household needs.

Abstract:Abstract: The continuous use of an electric motor in some industries causes the electric motor to malfunction early. Such damage is generally caused by overheating. Therefore, to overcome the problem of overheating, most…
industries use two motors that work alternately. Both electric motors function as running and standby which are generally controlled manually by the operator or using a time delay relay (TDR). However, the control of both motors by the operator is not effective because it allows human error to occur. The use of TDR is also ineffective because it does not make the temperature of the electric motor a reference in controlling the work of the two electric motors. This research aims to produce a prototype that can monitor the temperature of the electric motor in real-time and control the electric motor based on the temperature of the electric motor. The Wemos D1R2 is used as a processor to control both electric motors and transmit the temperature of the electric motor to a smartphone via the internet. The MLX90614 sensor is used as an infrared-based temperature sensor. Based on the results of testing the overall performance of the prototype, it is known that the temperature readings of the electric motor are quite accurate with mean error and standard deviation of 0.13oC and 0.15oC, respectively. The prototype is also capable of controlling both electric motors automatically and controlling a cooler via a smartphone.

Abstrak: Penggunaan sebuah motor listrik secara terus menerus pada sebagian industri menyebabkan motor listrik tersebut mengalami kerusakan lebih awal. Kerusakan tersebut umumnya disebabkan oleh panas berlebih. Oleh karena itu, untuk mengatasi masalah panas berlebih tersebut maka sebagian besar industri menggunakan dua buah motor yang bekerja secara bergantian. Kedua motor listrik tersebut difungsikan sebagai running dan standby yang mana umumnya dikendalikan secara manual oleh operator atau menggunakan time delay relay (TDR). Namun, pengendalian kedua motor oleh operator tidaklah efektif karena memungkinkan terjadinya human error. Penggunaan TDR juga tidak efektif karena tidak menjadikan suhu motor listrik sebagai acuan dalam mengendalikan kerja kedua motor listrik tersebut. Penelitian ini bertujuan menghasilkan sebuah prototipe yang mampu mengawasi suhu motor listrik secara real-time dan mengendalikan motor listrik berdasarkan suhu motor listrik. Wemos D1R2 digunakan sebagai prosesor untuk mengendalikan kedua motor listrik dan mengirimkan suhu motor listrik ke smartphone melalui internet. Sensor MLX90614 digunakan sebagai sensor suhu berbasis infra merah. Berdasarkan hasil pengujian kinerja prototipe secara keseluruhan diketahui bahwa hasil pembacaan suhu motor listrik cukup akurat dengan mean error dan standar deviasi masing-masing 0,13oC dan 0,15oC. Prototipe juga mampu mengontrol kedua motor listrik secara otomatis dan mengontrol sebuah pendingin melalui smartphone.

onomical. Since the amount of electricity consumed by users cannot be precisely predicted, balancing generation with consumption necessitates accurate electrical load forecasting. This study focuses on load forecasting using the Adaptive Neuro-Fuzzy Inference System (ANFIS) method. The forecast developed targets daily peak loads, which fall under short-term load forecasting. The data used for this forecasting consists of historical daily peak loads from January 1, 2017, to June 9, 2022. The forecasting process involves parameters such as radius, squash factor, accept ratio, reject ratio, and epoch. The forecast accuracy is evaluated using the Mean Absolute Percentage Error (MAPE) metric. The results are then compared with PLN’s load forecasting, which employs the load coefficient method. The ANFIS-based forecasting achieved a MAPE of 1.879%, using networks Jaringan_24 and Jaringan_25. This MAPE value is slightly lower than PLN’s load forecasting MAPE of 1.917%, indicating better accuracy by the ANFIS method.
