Abstract

Floods are natural disasters that frequently occur and cause significant damage to human life, infrastructure, and the environment. This study designed and implemented a prototype of an early flood warning system based on the Internet of Things (IoT) integrated with Firebase Realtime Database. The system aimed to address the limitations of previous warning systems by providing more accurate information, faster response times, and easier accessibility. The prototype enabled real-time data access through a web-based application accessible via smartphones and was equipped with a DF Player module to deliver audio warnings. A scaled-down prototype (1:10) was tested using an ultrasonic sensor for water level measurement and a tipping bucket sensor for rainfall measurement. The results demonstrated 99% accuracy for water level measurements up to 200 mm, with a data response time of 1 second and text updates every 5 seconds. This system significantly improved the accuracy, update speed, information accessibility, and effectiveness of audio warnings.

Abstract

Perangkat elektronik yang bergantung pada listrik sering kali menyebabkan pemborosan energi akibat kelalaian pengguna dalam mematikannya. Untuk mengatasi permasalahan tersebut, dikembangkan penelitian mengenai Sistem Pengendali Parameter Ruangan berbasis Internet of Things (IoT) yang dapat mengontrol pencahayaan dan suhu ruangan secara otomatis berdasarkan indikator gerak, jumlah orang, suhu, dan pencahayaan. Sistem ini menggunakan sensor PIR, sensor infrared, LDR, sensor luminositas, dan sensor suhu yang diproses melalui board Arduino Uno, dengan keluaran berupa LCD, lampu, kipas DC, dan aplikasi Blynk IoT. Metode penelitian melibatkan pengujian akurasi sensor dan analisis kesalahan pengukuran. Hasil penelitian menunjukkan bahwa sensor BH1750 memiliki akurasi sebesar 99,86% dengan error  0,14% dalam pengukuran intensitas cahaya. Sementara itu, sensor DS18B20 dalam pengujian suhu menunjukkan error  0% saat suhu >29°C (kipas menyala) dan <27°C (kipas mati), serta error  10% pada rentang suhu 27-29°C (kipas mengikuti kondisi sebelumnya). Dengan demikian, sistem ini terbukti efektif dalam mengontrol pencahayaan dan suhu ruangan secara otomatis, sehingga dapat mengurangi pemborosan energi.

Abstract

Teknologi elektronika memanfaatkan Mikrokontroler sudah mulai banyak dikenal oleh masyarakat, terutama bagi masyarakat yang menekuni bidang teknik elektro, baik dalam bidang pendidikan maupun hanya sekedar menekuni hobi. Banyak jenis mikrokontroler yang ditawarkan oleh produsen, di antaranya adalah Arduino yang memiliki keunggulan berupa kemudahan dalam merangkainya dan kesederhanaan dalam pemrogramannya. Arduino juga memiliki banyak varian yang dapat dipilih sesuai kebutuhan jumlah port maupun daya tampung memory yang tersedia di dalamnya. Arduino sering digunakan sebaga unit pengolah data yang diambil dari sensor sebagai input, dan menghasilkan output berupa aktuator. Meskipun sudah mulai dikenal dan diimplementasikan, masih banyak masyarakat yang awam dengan mikrokontroler Arduino ini. Oleh karenanya perlu diupayakan pengenalan lebih mendalam mengenai mikrokontroler Arduino, disertai contoh-contoh rangkaian yang dapat dibentuk oleh perangkat mikrokontroler ini. Tim memilih siswa-siswi SMK di daerah Puwodadi Grobogan sebagai obyek pengenalan dan pelatihan, mengingat para siswa sudah mendapatkan pengenalan dasar tentang mikrokontroler, sehingga selanjutnya dapat dikembangkan dengan implementasi yang lebih luas. Metode yang digunakan berupa tutorial disertai beberapa contoh rangkaian nyata yang sudah jadi dan berfungsi untuk berbagai kebutuhan. Hasil dari program ini siswa SMK yang sebelumnya hanya mengenal satu jenis mikrokontroler Arduino menjadi lebih mengenal berbagai tipe Arduino dan implentasinya secara lebih luas.Electronic technology utilizing Microcontrollers has begun to be widely known by the public, especially for people who are studying electrical engineering, both in education and just pursuing a hobby. Many types of microcontrollers are offered by manufacturers, including Arduino which has the advantage of being easy to assemble and simple in programming. Arduino also has many variants that can be selected according to the number of ports and memory capacity available in it. Arduino is often used as a data processing unit taken from sensors as input, and produces output in the form of actuators. Although it has begun to be known and implemented, many people are still unfamiliar with this Arduino microcontroller. Therefore, it is necessary to make an effort to introduce Arduino microcontrollers more deeply, accompanied by examples of circuits that can be formed by this microcontroller device. The method used was a tutorial accompanied by several examples of real circuits that were finished and functioning for various needs. The result of this program is that vocational school students who previously only knew one type of Arduino microcontroller become more familiar with various types of Arduino and their implementation more widely.

Abstract

A reliable electrical grid the power plant scheduling system needs to optimize the plant's performance by considering the economic value and the value of emissions generated by the plant, in addition to the reliability and economic sectors. This system should also take into account the environmental impact, as well as the CO2 and CH4 emissions produced by the plant. This research will use the Dragonfly Algorithm with weighting parameters to schedule hydro and thermal facilities' emissions and economic activities. That the weighting value impacts production costs and emissions is demonstrated by the data acquired from the Dragonfly Algorithm simulation. If economic considerations take precedence in assigning weights, then low-cost generating will result in high-value emissions, and vice versa. The plant's Emission Intensity rating also meets the standards established by the government.

Abstract

This study aims to analyze the operational condition of the distribution transformer at substation PY094, PLN ULP Pringgabaya, with a primary focus on identifying and calculating the level of load imbalance on the consumer side. Data were collected through direct measurements of electrical parameters, including voltage and current in each phase, followed by a detailed analysis of energy losses. The measurement results indicated a significant load imbalance. In Feeder B, the average phase currents were recorded at 103.8 A for phase R, 130.2 A for phase S, and 90.4 A for phase T. Meanwhile, in Feeder D, the average phase currents were 47.4 A for phase R, 18 A for phase S, and 20.4 A for phase T. This imbalance caused notable power losses in the distribution system, with an estimated daily energy loss of 28.94 kWh, assuming the system operates 12 hours per day. To address this issue, load balancing simulations were carried out using ETAP software. The simulation involved redistributing load values across each phase in the two main feeders. Feeder B was simulated at 46.82% of the transformer’s full capacity, while Feeder D was simulated at 12.38% of the total 160 kVA capacity. The simulation results demonstrated that redistributing the load significantly reduced the current imbalance, thereby minimizing power losses and improving the operational efficiency of the distribution substation. Therefore, load balancing strategies are essential for enhancing energy efficiency and ensuring the reliability of electricity supply in distribution networks.
