Placement for Condition Monitoring of Rotating Machine Elements Based on HSD: Penempatan untuk Pemantauan Kondisi Elemen Mesin Berputar Berdasarkan HSD
Full text linkCareful placement and selection of sensors is the key to accurate motorbike monitoring. This research aims to develop an optimal sound sensor placement strategy for monitoring the condition of induction motor bearing elements. Sensor placement will affect monitoring accuracy. The nature of sound signals is that they easily overlap with surrounding sounds. Different placement of sound sensors will provide opportunities for non-motor sounds to overlap. The bearing condition monitoring system was developed in real time by processing sound signals using fast Fourier transform (FFT). The sensor placement strategy needs to be taken into account so that monitoring results obtain high accuracy. The honestly significant difference (HSD) approach is a test used to determine the best sensor placement. Tests were carried out with variations in the placement of sound sensor distances and different levels of bearing damage. The results of the research are the best sensor placement at a distance of 110 cm from the motor body with a detection accuracy of 94.14%
Real-Time IoT-Integrated Ground Control Station (GCS) for Unmanned Aerial Vehicle (UAV) Monitoring System
Full text linkConventional Ground Control Stations (GCS) for UAVs are often platform-bound (PC-only or Android apps), creating installation overhead and constraining mobility. This work introduces a browser-native, web-based GCS that runs across devices without prior installation and ingests MAVLink telemetry from a RadioLink Mini Pix V1.0 flight controller via 433 MHz UART radio telemetry, then streams decoded data to the UI over websocket/JSON. The system visualizes attitude (yaw, pitch, roll/IMU), GPS position and mapping, compass bearing, altitude, and flight status in real time, with user authentication and a structured landing/login flow. In controlled tests, the application delivered stable live visualization and accurate mapping during a 100 m out-and-back flight, with reported coordinates matching the route. Link-budget characterization across 95, 100, 180, 190, and 240 m showed the expected RSSI degradation with distance and a pronounced dip at 190 m, a practical safe range of ~100 m was identified where signal strength stayed >50% with low interference. Compared with PC or Android-based GCS, the proposed approach improves accessibility (zero-install, multi-device) and operational flexibility, while maintaining reliable real-time telemetry for mission monitoring

Implementation of Load cell Sensors as Monitoring the Weight of Infusion Fluids in Inpatients Based on Internet of Things (IoT): Implementasi Sensor Load cell Sebagai Pemantau Berat Cairan Infus Pada Pasien Rawat Inap Berbasis Internet of Things (IoT)
Full text linkThe use of electronics for medical purposes is currently very much needed, especially for monitoring infusion fluids. Infusion plays an important role in supporting the needs of inpatients as medicine, vitamins or replacing the patient's body fluids. One problem that often arises is the delay in replacing infusion fluid bags that have run out. If the infusion fluid runs out and the replacement is late, blood from the vein can enter the infusion tube, as well as air bubbles entering the vein. This condition can be fatal because blood flow is disrupted, and the oxygen the body needs cannot be distributed through the blood, so the body's organs will lack oxygen. Currently it is still controlled manually, so with research on an infusion monitoring system using a Load cell sensor which can be monitored remotely, it makes the nurse's time more efficient. In this research, the results of tests that have been carried out regarding load cell sensor readings have a 100% success rate in detecting the weight of infusion fluid from full condition until the fluid is considered finished and the data can be sent in real-time to Android by utilizing Internet of Things (IoT) technology
Performance Analysis of Three Phase Induction Motor at PT. Intracawood Manufacturing
Full text linkTo support the production process in an industry, there are many electric motor equipment in the form of induction motors. Induction motors are the most widely used motors in various fields, ranging from household environments to large-scale industries. Induction motors that are used continuously do not guarantee that they will always work normally, meaning that the motor can experience damage. These damages can affect the performance of the reduced induction motor. To find out the performance of the motor at PT. Intracawood Manufacturing, an analysis was carried out on the Blower Sander, Rotary, Conveyor Dry, and Conveyor Finishing motors, respectively on taking motor data based on the name plate and the motor in the current condition that was running or after rewinding. Motor performance analysis was conducted by calculating current, input power, output power, load torque, induction torque, and efficiency. From the calculation results, the Blower Sander motor by taking motor on the name plate with a current of 103 A, obtained an input power of 58.979 kW, an output power of 51.214 kW, an induction torque of 335.12 N.m, a load torque of 330.62 and efficiency of 86,83%.

An Accuracy Assessment of an IoT-Based Monitoring System for Household Water Consumption in Estimating Volume and Usage Cost: Analisis Tingkat Akurasi Sistem Monitoring Konsumsi Air Rumah Tangga Berbasis IoT terhadap Estimasi Volume dan Biaya Pemakaian
Full text linkWater-use efficiency in the household sector is a crucial aspect in supporting the sustainability of water resources. Enhancing this efficiency requires a monitoring system capable of accurately measuring consumption volume and precisely estimating usage costs. A relevant approach in this context is the implementation of Internet of Things (IoT)-based technology, which enables real-time data acquisition and transmission through smart water meter devices. This study aims to evaluate the accuracy of an IoT-based household water consumption monitoring system in estimating usage volume and calculating cost. The method involves a comparison between actual water flow data and system measurements, as well as an analysis of the discrepancy between actual costs and cost estimates produced by the application. Experimental results indicate an average deviation of 9.12% between the actual and measured volume. In contrast, the cost estimation demonstrates a very high level of accuracy, with a maximum discrepancy of only IDR 1 compared to the actual cost. These findings indicate that the system performs reliably in estimating cost, although some inaccuracies remain in volume measurement. Overall, the system demonstrates considerable potential as an effective and sustainable technological solution to support household water consumption management

Full text linkWater is a vital resource for life on earth and a primary human need. This research is motivated by water management issues within the Al-Amanah Modern Islamic Boarding School, where the tank filling process is still carried out manually, often resulting in waste and the absence of water level indicators. To address this issue, an Internet of Things (IoT)-based water level control system was designed. This system utilizes an ultrasonic sensor to measure the water level, a NodeMCU ESP8266 as the main controller, and the Blynk application to monitor and control the system via a smartphone. A relay is used to automatically turn the water pump on and off. Data from the sensor is processed by a microcontroller, sent to the Blynk server, and displayed in real time in the application. Test results show that the system is able to monitor and regulate water filling more efficiently, although overall performance still has room for improvement.
