Abstract

Currently, the Electrical Engineering Laboratory (EEL) of Universitas Jenderal Achmad Yani has a 1 kWp photovoltaic (PV) system. However, in order to fulfill the overall load, the hybrid link to the grid must be improved. The PV system and the grid must be synchronized in terms of voltage, frequency, and phase. This article presents comparative simulations of AC-AC converter models of power electronics component variants using MATLAB 2019a. Among other stages is to model the DC-DC Converter in order to enhance the output voltage of the solar panel by identifying the circuit characteristics. The second stage involves simulating the MOSFET-based DC-AC Converter circuit, which is used to convert DC to AC. The use of switching Thyristor, Gate Turn-Off Thyristor (GTO), and Insulated Gate Bipolar Transistor (IGBT) in an AC-AC phase converter to connect to the grid is examined in this range. Non-linear and linear loads are used to represent the load on the AC Cycloconverter range. Based on the results of the modeling and analysis of the PV 1 kWp system, the AC Cycloconverter in the first stage may provide a frequency of 50 Hz with a voltage drop of 235.4 V for the line and 231.9 V for the non-linear, which meets the AC Cycloconverter criterion.

Abstract

Indonesia's renewable energy mix offers an alternative to conventional fossil fuels. Indonesia has made a significant commitment to the role of exploiting this new energy in accordance with the Paris Agreement. This paper proposes the design of a microgrid architecture for a solar and wind hybrid power plant with grid-connected configuration and micro-scale power plant modeling in Ciheras Village, Cipatujah District, Tasikmalaya Regency, West Java. This architecture is divided into three scenarios in order to determine the best design qualities. The first scenario involves 50% photovoltaic (PV) and 50% wind turbine (WT), the second 60% PV and 40% WT, and the third 70% PV and 30% WT. The findings of the grid-connected microgrid were compared using supporting software, HOMER Pro. The various scenarios yielded performance analysis and renewable energy contribution. Modeling, calculation, simulation, and analysis demonstrate that the first scenario's potential energy output produces 25,655 kWh/year with an 88.2% Renewable Fraction (RF). The second scenario generates 26,194 kWh of energy per year, with a renewable fraction of 87.8%. The third scenario is the best based on the participation and role of distributed energy (PV-WT), with a higher amount of energy output of 30,691 kWh/year and a higher renewable proportion of 89%.

Abstract

The availability of electrical energy ensures operational sustainability in everyday life, including the educational environment. The possibility of easier renewable energy installation encourages the goal of growing the installation to be affordable. Universitas Jenderal Achmad Yani is one of the campuses that has the capacity to use renewable energy and has a role in environmental awareness in accordance with the university's future vision. In light of this, a hybrid photovoltaic (PV), diesel, and battery plant design is presented as an alternative power plant to supplement conventional energy sources. However, it is critical to examine the long-term capital and profit estimations that must be considered. The hybrid plant is proposed in two configurations, grid-connected and off-grid. In this paper, modeling and simulation are performed using Net Present Cost (NPC) prices from the Ministry of Energy and Mineral Resources (MEMR) rooftop PV installation planning guidelines and inflation estimations from the Republic of Indonesia's Ministry of Finance. Furthermore, until the contribution of energy generated in the simulation is displayed, the production and consumption of electrical energy required for the selected building instances are generated. Hybrid plant modeling has been completed at Universitas Jenderal Achmad Yani’s Faculty of Health Sciences and Technology (FHST) and Rectorate buildings. According to the simulation results, the NPC cost for the next 25 years is anticipated to be Rp 1,047,534,000, with a total electrical energy production of 729,807 kWh/year and a renewable energy contribution >91.4%. Furthermore, from a technological and economic standpoint, a grid-connected hybrid generation system is advocated

Abstract

Electrocoagulation (EC) has increasingly been used in wastewater treatment, including palm oil mill effluent (POME), due to its ease of operation and less sludge production. In this study, POME was treated using an integrated aeration and EC process, which was conducted continuously at a constant flow rate of 500 mL.min-1. The agitation process was applied in the EC reactor at a rotating speed of 20 rpm to shorten the electrolysis reaction time. The EC reactor was equipped with 6 electrodes as baffles. Two current densities (12 and 15A.m-2) and electrode configurations (3A-3C and 2A-2C-2B) were used, and the resulting effluents were compared. The experimental results showed that the highest contaminant removal was achieved with the electrode configuration 2A-2C-2B and the current intensity was 15 A. The BOD removal efficiency was 91.36% (from 132 to 11.4 mg.L-1), COD of 81.27% (from 386 to 72.3 mg.L-1), TDS of 47.64% (from 645.5 to 338 mg.L-1), TSS of 76.27% (from 43.7 to 10.4 mg.L-1), and turbidity of 96.46% (from 59.65 to 2.11 NTU). Meanwhile, the total energy requirement was 21.33 kWh.m-3 with the pH of the effluent of 8.05. The combination of aeration-EC can be used as an alternative POME treatment to achieve high contaminant removal efficiency.

Abstract

West Bandung Regency, West Java Province, is one of the areas with a significant earthquake risk due to the activity of the Lembang Fault and regional geological conditions. Earthquakes that occur suddenly may cause serious impacts on human safety, infrastructure, and activities in campus environments and public buildings. The limited availability of local, real-time, and easily accessible earthquake early warning systems highlights the need for an effective mitigation technology based on the Internet of Things (IoT). This study aims to design and implement an ESP32-based earthquake early warning system prototype integrated with Telegram notifications. The proposed system employs an MPU6050 sensor to measure vibration acceleration along the X, Y, and Z axes, while an SW-420 sensor is used as an initial vibration detector. The acceleration data are processed using the Root Mean Square (RMS) method and the Short Time Average/Long Time Average (STA/LTA) ratio to classify vibration conditions into four warning levels: safe, alert, warning, and danger. The classification results are displayed through local indicators and transmitted in real time to Node-RED using the MQTT (Message Queuing Telemetry Transport) protocol, then forwarded to users through Telegram notifications. The experimental results show that the system is capable of detecting vibration with a success rate of approximately 95%, a classification accuracy of 92%, and a data transmission delay of less than one second. Therefore, the proposed system has the potential to be implemented as a low-cost, responsive, and easily deployable earthquake early warning solution in earthquake-prone areas.

Abstract

The global issue of increasing amounts of waste in water areas has been very detrimental to the environment and has become a serious concern due to its impacts, especially on water quality, which can disrupt aquatic ecosystems and cause public health problems. Current conventional cleaning methods still rely on manual labor, which is time-consuming and inefficient. This study proposes a solar cell-based and Internet of Things (IoT)-enabled waste transport vessel and utilizes sensors in its design. This prototype was built using an ESP32 microcontroller as the main control unit, two HC-SR04 ultrasonic sensors for waste detection and container level monitoring, servo-based waste pickup, and a DC motor-driven conveyor. Remote monitoring and supervision are implemented through the Blynk IoT platform, enabling actual and real-time system observation. The prototype was built and evaluated, showing an average response time of 4.0–5.2 seconds across various types of waste samples; sensor calibration yielded good linearity (R² = 0.9987) and an average distance error of only 2.08 mm. Stable buoyancy testing where the prototype was able to hold a total mass of 1.73 kg. The solar cell successfully charged a parallel Li-ion 18650 battery bank from 3.40 V to 3.75 V over a period of 5 hours, resulting in a near-neutral daily energy output (~3.43 Wh consumption vs. ~3.38 Wh generation). IoT telemetry successfully monitors and stores data in the cloud efficiently. These results enhance operational reliability, energy efficiency, and control systems that benefit the environment, making this technology a promising solution for sustainability and addressing environmental issues, particularly in aquatic environments. Further research is expected to focus on real-world, dynamic field applications by integrating multi-sensor data and waste classification.
