Abstract

Fossil fuel power plants are still used as a source of energy around the world and have a significant impact on emissions and environmental pollution. To reduce these emissions, renewable energy offers a solution that can be applied in future housing. This study proposes a simulation using HOMER to determine the most cost-effective composition of hybrid renewable energy systems in housing. This simulation can combine photovoltaic (PV) systems, wind power (WP), and a converter that functions to change DC to AC from PV to obtain an alternating current (AC) system. The hybrid combination of PV and WP proves to be the most appropriate and economical choice at the research location. The results of the study showed that the installation of a hybrid system in housing, with an initial investment cost of IDR 107,474.43 million and an annual operating cost of IDR 22,540.23 million, is 41% lower than conventional fossil fuel-based systems. Research data shows that the project's payback period is estimated to be around 11 years. These findings can be recommendations for similar systems in regions with similar contours and geography. Apart from that, positive monetary impacts can provide incentives for policymakers to implement similar hybrid systems, thereby contributing to the goal of global emissions neutralization.

Abstract

The use of fossil fuel power plants will contribute to emissions and environmental pollution, which has an impact on air and environmental pollution. Applying hybrid energy systems can help reduce the emission footprint and improve the stability of local electricity networks, especially in services with high energy consumption. Hybrid optimization of multiple energy resources (HOMER) is a simulator that simulates using renewable energy with the hybrid renewable energy systems (HRES). The simulation produces a system with the most appropriate combination of photovoltaic (PV), wind power (WP), and converter. The combination of PV-WP produces an economical choice for providing electrical energy in a particular location. The hybrid PV-WP model can save about 40.8% less than the current condition. The investment can be returned in 10.11 years, which is recommended for similar conditions in other areas. This positive impact can provide incentives for policymakers in the implementation of a hybrid system that can neutralize emissions and environmental pollution.

Abstract

Distribution transformer is a component in distributing electricity from distribution substations to consumers. Damage to distribution transformers causes continuity of customer service to be disrupted (power cut or blackout occurs). The length of the PLN electricity network requires a transformer to distribute electricity to serve consumers and how to maintain the transformer. The daily load curve of a peak load for housing, shops and factories / industries varies. Load served 200 kVA distribution transformer cannot serve the load on housing, shops and factories / industry. The method used is the replacement of a distribution transformer with a capacity of one stage greater or the replacement of a distribution transformer with a capacity of two levels larger. The distribution transformer carried out by the research is a capacity of 200 kVA replaced by 250 kVA. The ability of a distribution transformer cannot accommodate a load which will increase as an area is advanced. Observations made by calculating the age of the transformer by assuming the annual load growth (r) = 3% = 0.3. Annual peak load (P) = 1.8 p, u increase in oil temperature at peak load (θo = 96.21 0C; 84.16 0C). The increase in the hottest temperature above the oil cover, the increase in the temperature of the hottest place above the oil (θg = 20 0C; 20 0C). The ratio of the load loss to the nominal load excitation loss (Q = 3; 30). By assuming the values of these methods it can be estimated that the life of a distribution transformer is 20 kV, a capacity of 200 kVA is 18 years.

Abstract

Penelitian ini menelaah bagaimana klasterisasi spektrum VHF dapat mengurangi potensi interferensi antarbandara di ruang udara Indonesia yang padat. Berlandaskan konsep interaksi spasial dan risiko spectrum sharing, kedekatan geografis antarbandara dan jarak frekuensi (Δf) dikaitkan dengan probabilitas terjadinya interferensi, serta memosisikan klasterisasi sebagai prasyarat koordinasi berbasis data. Data multi-layanan VHF dari 219 bandara dinormalisasikan dan dianalisis, Menggunakan Principal Component Analysis (PCA) untuk mempertahankan komponen yang menjelaskan ≥70% variasi, Selanjutnya, algoritma FASTCLUS digunakan untuk membentuk kelompok yang koheren secara spasial. Pasangan bandara yang berpotensi berisiko diidentifikasi dengan kriteria jarak <50 km dan Δf <0,2 MHz (uji kepekaan: 0,3 MHz). Hasil analisis menunjukkan terdapat 37 pasangan bandara memenuhi kedua kriteria tersebut; pola yang teridentifikasi menunjukkan adanya kantong kepadatan dengan penyempitan adjacent-channel spacing yang mengindikasikan kemungkinan inertia kebijakan dalam pengelolaan spektrum (spectrum housekeeping). Berdasarkan temuan tersebut, disusun daftar prioritas watchlist berperingkat untuk AirNav/Kominfo guna memandu penataan ulang kanal dan koordinasi lintas wilayah, mendukung SDG 9 dan SDG 16. Pendekatan yang digunakan mengintegrasikan PCA–FASTCLUS dengan skrining Δf–jarak menjadi pipeline praktis, replikabel, dan siap regulator.

Abstract

Abstract: The development of Internet of Things (IoT) technology has driven progress in electrical device monitoring and control systems, especially in single-phase installations. This research aims to design and implement an Android-based single-phase electrical load monitoring and control system by utilizing the PZEM-004T sensor to measure voltage, current, and power in real-time. This system uses two microcontrollers, namely Arduino Nano as the main processor of sensor data and ESP32 to send data to the Blynk application via a WiFi connection. The Blynk application serves as a user interface, enabling remote monitoring and control of electrical loads through a smartphone. Three PZEM-004T sensors are used to monitor three separate load channels, while a 4-channel relay module acts as an actuator to control the ON/OFF status of each load. The system was tested under various load conditions to verify the accuracy of the sensor readings and the responsiveness of control commands via Blynk. This system is not only effective for monitoring and controlling power usage efficiently, but it also holds great potential as a learning tool in the fields of electronics and IoT-based electrical system applications for residential or laboratory environments. Keywords: Internet of Things, ESP32, PZEM-004T, Load Monitoring, Power Control  Abstrak: Perkembangan teknologi Internet of Things (IoT) telah mendorong kemajuan dalam sistem monitoring dan kontrol perangkat listrik, terutama pada instalasi satu fasa.

Abstract

Abstract: Promotion is an activity carried out to convey, disseminate, and offer products, so that potential consumers are interested in buying. In the implementation of the promotion, CV. Pentaland Jaya abadi uses website media and brochures that still contain 2-dimensional images and information about housing so that potential consumers are less interested because consumers cannot see the exterior and interior shapes directly. Potential consumers usually get brochures through project locations that are still under construction, after that contact the marketing department. One way to solve this problem can be to use augmented reality technology with the appropriate development method is the Multimedia Development Life Cycle (MDLC) which includes Concept, Design, Material Collecting, Assembly, Testing, and Distribution so that this research can produce an android-based augmented reality application that can display 3 dimensional virtual shapes from 3 housing estates including calista haus, grand ayahanda residence and calista homey. From each housing produces 3 dimensional objects on the exterior and interior so that it can provide interest in buying house objects and in addition to that it also helps in the marketing department in promoting housing objects without the need to show many miniatures that require time and also large places. Keywords: Wind Power Plant, Internet of Things, Blynk, ESP32, Charging Module.

Abstract

Abstract: This research aims to design an automatic buggy vehicle driver system based on the ESP32 microcontroller at Medan Aviation Polytechnic. The system is designed to enhance the operational efficiency of campus vehicles, enabling them to operate autonomously without requiring a direct driver. The ESP32 microcontroller serves as the central controller, regulating the DC motor for steering, pneumatic motors for gas and brake pedals, and a motor driver to control the current to the motors. The system's performance testing showed that the power required for the pneumatic motors (gas and brake) is 36 watts, and for the DC motor steering, it is 72 watts. Turning tests at a 90° angle and braking tests, where the braking distance was reduced by 10 cm after calibration, indicated that the system operates as expected. These tests confirmed the system's responsiveness and accuracy in automatic operation. Technical challenges in testing, such as adjusting sensor sensitivity and calibrating the pneumatic system, were addressed through repeated trials. This research contributes to the development of vehicle automation in educational settings and offers potential for further advancement, such as integrating LiDAR and GPS sensors for improved navigation accuracy. Keywords:  Automatic Buggy Vehicle Driver, Microcontroller, ESP32, Control System, Vehicle Automation Abstrak: Penelitian ini bertujuan merancang sistem penggerak mobil buggy otomatis berbasis mikrokontroler ESP32 di Politeknik Penerbangan Medan.
