Abstract

Water 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.

Abstract

Blind people are often hampered in their mobility, while currently available assistive technology includes manual sticks and electronic mobility devices. Currently, the development of smart canes is still being carried out in many studies. Smart cane works by detecting the distance of the cane to obstacles in front of you. From detecting this distance, the response the user gets is generally in the form of vibrations and sounds from the buzzer. The sound provided by the buzzer cannot differentiate the distance between obstacles. Therefore, this study proposes the existence of additional sound playback responses to differentiate far, middle, and near obstacles. Apart from that, the design of the prototype refers to the shape of a flashlight. The smart cane is designed using an Arduini UNO microcontroller with a rechargeable battery power supply with three response components, namely two ISD 1820 modules connected to a speaker to detect long distances (201-300 cm) with a "Hati-hati" sound and medium distances (101-200 cm) with an "Awas" sound, as well as a buzzer and piezoelectric component in the form of a "beep" sound and vibration for close distances (1-100 cm) to obstacles. The result is that both the ultrasonic sensor and response components work according to design. Apart from that, the rechargeable battery supply feature and the implementation of the prototype design make it easier for users to store and use for daily activities.

Abstract

Class imbalance is a common problem in health datasets and often leads to poor recognition of the minority (disease) class. NR-Clustering-SMOTE is a cluster-based oversampling method that combines noise reduction, K-Means clustering, and SMOTE with a modified distance metric to improve classification performance on imbalanced health data. However, the original method only performs noise reduction before SMOTE, so noisy synthetic samples generated around borderline or highly overlapped regions may still degrade classifier performance and introduce epistemological bias in the learned decision rules. This paper proposes a lightweight extension called NR-CluSMOTE-KNC (NR-Clustering-SMOTE with Post-SMOTE k-NN Cleaning). After the standard NR-Clustering-SMOTE pipeline, a k-nearest neighbour filter is applied solely to synthetic minority samples; synthetic points that are surrounded predominantly by majority neighbours are identified as extreme noise and removed. On the Pima Indians Diabetes dataset using Random Forest, the proposed method improves accuracy from 0.8481 (baseline NR-Clustering-SMOTE) to 0.8589 with NR-CluSMOTE-KNC, accompanied by consistent gains in G-Mean and AUC. These results indicate that a simple post-SMOTE cleaning step can epistemologically refine the representation of minority concepts in the data, producing more reliable and fair predictive models for health decision support.

Abstract

ABSTRAK Energi sangat penting untuk mendukung aktivitas manusia, namun sebagian besar pasokan masih bergantung pada bahan bakar fosil yang tidak terbarukan. Desa Singogalih di Kecamatan Tarik, Kabupaten Sidoarjo, menghadapi keterbatasan pasokan listrik, terutama di area persawahan, sehingga penerangan jalan menjadi terbatas dan berpengaruh terhadap keamanan masyarakat. Penelitian ini merancang Pembangkit Listrik Tenaga Piko Hidro (PLTPH) berbasis turbin Archimedes Screw dengan sistem monitoring Internet of Things (IoT) sebagai solusi penerangan jalan. Metode penelitian meliputi studi literatur, perancangan, pembuatan, dan pengujian alat selama tiga minggu. Hasil pengujian menunjukkan peningkatan kinerja sistem, dengan putaran generator naik dari 226,9 RPM menjadi 384,4 RPM dan tegangan dari 6,5 V menjadi 11 V, serta baterai mampu terisi penuh untuk menyalakan lampu LED melalui sistem Control Charger (CC). Solusi ini dinilai efektif, ramah lingkungan, dan berkelanjutan untuk penerangan pedesaan.

Abstract

Solar panels are semiconductor elements that can convert solar energy into electrical energy. This Research on Solar Power Plants (PLTS) assemble with materials such as solar panels, 3000 W inverters, batteries, relays and control chargers, after that the load calculations are carried out, then implementation and testing is carried out. This research also aims as a renewable electric power in the future. From the results of the PLTS load test carried out at the researcher's house, the highest load was 405.32 watts, while the highest load test results used PLN electricity, which was 267.06 watts. So it can be said that this research is successful in meeting the electricity needs of household scale.

Abstract

To realize energy savings, especially electrical energy on a household scale, one thing that is usually done is turning off unnecessary equipment. However, this kind of conventional method requires high discipline and the success rate is quite low due to many factors, one of which is forgetting. One solution that can be applied to this problem is the need for tools that can force electricity users to turn off electricity if usage has exceeded a certain limit. To be able to measure electricity consumption, an energy measuring sensor is used which is then processed on the microcontroller and drives the circuit breaker relay. In making this tool using the experimental method, by planning based on references from the literature and experiments directly to the equipment. With this, it is hoped that the expected tools will be realized and can contribute to saving energy in the community.

Abstract

Terminal bandara merupakan fasilitas publik yang harus memberikan kenyamanan termal dan kualitas udara yang baik bagi penumpang maupun petugas. Pengelolaan sistem Heating, Ventilation, and Air Conditioning (HVAC) secara manual berpotensi menyebabkan ketidaksesuaian suhu, pemborosan energi, dan kurang optimalnya pemantauan kualitas udara. Penelitian ini bertujuan merancang dan mengimplementasikan sistem monitoring dan kendali HVAC berbasis Internet of Things (IoT) untuk meningkatkan efektivitas pengelolaan lingkungan terminal bandara. Sistem menggunakan sensor DHT22 untuk mengukur suhu dan kelembapan, sensor MQ-135 untuk memantau kualitas udara, mikrokontroler ESP32 sebagai pengolah data, serta aplikasi MIT App Inventor sebagai antarmuka pengguna. Sistem mampu melakukan monitoring secara real-time serta pengendalian HVAC secara otomatis maupun jarak jauh. Hasil pengujian menunjukkan keberhasilan pengiriman data dan kendali sebesar 100%, dengan rata-rata waktu pembaruan data 2,17 detik dan waktu respons kendali 1,23 detik. AC aktif otomatis saat suhu melebihi 27°C, sedangkan exhaust fan bekerja ketika kualitas udara melebihi 150 ppm. Sistem mampu menjaga suhu ruangan pada kisaran 26,2–26,99°C sesuai standar kenyamanan terminal bandara. Hasil penelitian menunjukkan bahwa sistem HVAC berbasis IoT dapat mendukung penerapan konsep Smart Airport secara efektif dan efisien..
