Abstract

The DH Building of the Electrical Engineering Study Program at Udayana University faces significant challenges in energy efficiency, as it still relies on conventional electrical systems. User negligence, such as forgetting to switch off lights and air conditioners (AC) after use, often results in unnecessary energy waste and increased operational costs. This issue highlights the urgent need for smart solutions capable of automating energy management, reducing waste caused by human error, and supporting the creation of a more efficient and sustainable campus environment. To address this problem, this study designs and implements a smart building system based on the Internet of Things (IoT). The system employs a NodeMCU ESP32 microcontroller as the main processing unit, integrated with a series of sensors including a DHT22 sensor for monitoring temperature and humidity, an MQ2 sensor for smoke detection, a PIR sensor for motion detection, and a PZEM-004T sensor for monitoring energy consumption. Control of electronic devices such as lights and AC units is carried out both automatically and manually through relay modules connected to the system. All sensor data and control functions are accessed via a web interface developed using the Laravel framework and a MySQL database. The testing results indicate that the designed system was successfully implemented and functions as expected. Sensor testing demonstrated high accuracy compared to standard measuring instruments, while the electronic device control system achieved an average response time of approximately 3.6 seconds, proving its reliability. Overall, the system provides a comprehensive solution for energy consumption monitoring and control, while also enhancing comfort and safety in the DH Building, in line with the goals of energy efficiency and facility modernization.

Abstract

Indonesia sebagai negara tropis memiliki potensi energi matahari yang cukup besar dengan memanfaatkan dua tipe dasar tenaga matahari berupa cahaya matahari dan panas matahari. Thermoelectric Generator (TEG) merupakan pembangkit listrik skala kecil yang mengubah sinar matahari secara langsung menjadi panas atau energi listrik berdasarkan efek Seebeck. TEG dibuat menggunakan bahan padat atau semikonduktor dengan sisi panas dan dingin. Sisi dingin TEG akan terkonsentrasi menggunakan air es dan heatsink sebagai media sedangkan pada sisi panas digunakan aluminium sebagai kolektor dengan penambahan kaca pembesar untuk memfokuskan cahaya matahari, tetapi perubahan cuaca dapat menyebabkan keluaran TEG bervariasi. Pada penelitian ini juga dilakukan pemantauan data suhu, arus, dan tegangan berbasis IoT selama periode waktu tertentu untuk menganalisis apakah perangkat TEG bekerja secara efisien. Perancangan prototype ini menggunakan hardware yaitu mikrokontroler WeMos D1 R2, sensor DS18B20 dan sensor INA219 sedangkan software yang digunakan yaitu aplikasi Blynk dan Sktetcup pro. Sistem data logger memiliki tingkat akurasi yang tinggi dimana telah dilakukan pengukuran dengan cara membandingkan sensor DS18B20 dengan alat ukur thermometer dan sensor INA219 dengan avometer. Hasil dari penelitian ini yaitu Prototype telah berhasil menghasilkan daya listrik dimana perbedaan suhu sangat berpengaruh terhadap output yang dihasilkan. Pada penelitian ini juga berhasil menampilkan dan menyimpan data suhu, arus, dan tegangan pada aplikasi Blynk.

Abstract

The sunlight intensity level requirement for dragon fruit plants is more than 90%, which is essential for the photosynthesis process and the morphological development of the plant. This plant is classified as long-day plant, meaning that it requires at least 12 hours or more of sunlight to reproduce. Dragon fruit farmers utilize artificial lighting as an alternative to sunlight to support the plant's biological processes at night. The energy source is conventional electricity from grid (PLN). The design of an off-grid PV system at the Yosomulyo dragon fruit farm is carried out to support the farm's daily electricity needs. The design begins with field observations to obtain geographic data of the farm, daily electrical load profile data with amperes, calculating the PV system capacity, determining PV system components, and testing the performance of the design with PVSyst simulation. The simulation results of the PLTS design are 70.9% with an inverter variation of 6500 W, solar modules of 550 Wp, batteries of 200 Ah 12 V at a system voltage of 48 VDC, and an autonomy day of 1.

Abstract

The increasing number of vehicles has led to several complex challenges, such as traffic congestion, air pollution, and safety driving issues. These challenges also result in economic losses. Fortunately, with the advance in technologies today, we can utilize Intelligent Transportation Systems (ITS) to establish a system that is more efficient, safer, and environmentally friendly. Specifically, the concept of Vehicle-to-Everything (V2X) has emerged as a potential solution to address various road-related challenges. However, the real-world implementation of V2X still faces numerous obstacles, particularly in terms of cost and safety concerns. Deploying V2X on a large scale requires significant investments due to the need for communication infrastructure and hardware development. Therefore, simulation can serve as an initial solution to tackle these challenges. Simulations make it possible to set up different communication network protocols and architectures and to model different traffic conditions without the risks that come with testing in the real world. In this review paper, we aim to give a clearer insight into the trends, challenges, and opportunities of V2X simulations in various traffic environments.

Abstract

This paper presents a model of a batteryless off-grid photovoltaic (PV) system with an adaptive multi-motor load. This model is developed as an effort to enhance the power output of batteryless off-grid PV systems for motor loads. Instead of using a single large-capacity motor, as commonly done in previous studies, the model distributes the load into several smaller motors and controls them adaptively. This approach allows for better control of the total load impedance to support maximum power point (MPP) tracking. A case study involving three three-phase induction motors, each with an operating power of 200 W, is conducted, where the power production of the proposed model is analysed by comparing it with the theoretical MPP and a fixed-load motor system that represents a single large motor. Under 1000 W/m² irradiance and using an 852 Wp PV array, the proposed model achieves a power output of 842 W, which corresponds to 98.83% of the MPP. In contrast, the system without this model only generates 298 W, or just 35.02% of the MPP. The testing process spans a 5-second period during the motor starting state. The power production analysis of the proposed model is presented in graphical form using MATLAB/Simulink.

Abstract

Electrical installations in smart buildings have evolved significantly from conventional systems to Internet of Things (IoT)-based systems that emphasize energy efficiency, adaptability, and environmental sustainability. This study reviews literature from the past six years in Indonesia, focusing on aspects of installation design, monitoring systems, automation, and the application of sensor and microcontroller technologies to achieve energy efficiency. Various studies indicate that the implementation of IoT in electrical systems enables real-time monitoring of power consumption, automatic load control, and integration with centralized energy management systems. This technology not only enhances user comfort but also reduces operational costs and supports energy sustainability through electricity savings of up to 50%. Moreover, the use of wireless networks and smart sensors in modern buildings can identify abnormal energy consumption patterns and provide early warnings for potential failures or energy leakage. The implementation of such systems contributes to realizing the smart building concept that is efficient, safe, and environmentally oriented. Therefore, IoT-based electrical installations hold great potential for widespread application in supporting national energy efficiency initiatives and promoting sustainable development in the digital era.
