Abstract

Air pollution in enclosed spaces, particularly from carcinogenic substances such as smoke and hazardous gases, poses significant health risks. Effective detection and neutralization of these harmful compounds are crucial to ensuring indoor air quality and human safety. This study analysed the working system of a carcinogenic substance neutralization device that utilizes an MQ2 gas sensor and Arduino Uno for real-time monitoring and control. The system is designed to detect the presence of carbon monoxide (CO), liquefied petroleum gas (LPG), smoke, and other harmful gases using the MQ2 sensor. When the sensor detects a gas concentration exceeding a predefined threshold, the Arduino Uno microcontroller triggers an exhaust fan or an air purification mechanism to neutralize the pollutants. The system also features a real-time display and an alarm to alert users of hazardous gas levels. The experimental results indicate that the MQ2 sensor effectively detects gas concentrations with a fast response time. The Arduino-based control system efficiently activates the neutralization process, improving air quality in enclosed spaces. The integration of this system with smart monitoring devices can enhance air pollution management in industrial, residential, and commercial environments. This paper contributes to the development of low-cost, automated air purification systems for enclosed spaces, with potential applications in health safety, environmental protection, and industrial settings.

Abstract

The intensity of solar radiation is the main factor that affects the performance of solar cells in generating electrical power. This study modeled the effect of solar radiation changes on the power output of solar panels using Matlab/Simulink, with solar radiation data from Nasa Power for the Tanjung Anom location. The simulation was carried out to measure the output power based on variations in solar radiation intensity and ambient temperature in the effective time range, namely 09.00 to 16.00. The results show that the intensity of solar radiation is directly proportional to the output power of solar panels. At the highest radiation intensity of 620.35 W/m², the maximum power produced reaches 107.6 W, with a voltage of 20.35 V and a current of 5.286 A. On the other hand, at the lowest radiation of 205.61 W/m², the power decreases to 11.94 W. The model successfully illustrates the linear relationship between solar radiation, voltage, current, and output power, and shows the sensitivity of solar panels to changes in environmental parameters. Using MATLAB/Simulink, this model can be used to design and optimize photovoltaic systems according to local conditions. This research makes an important contribution to a deep understanding of the characteristics of solar cells, as well as a reference in the development of more efficient and environmentally friendly solar energy systems.

Abstract

Electricity distribution networks often face efficiency challenges due to uncompensated reactive power, causing power factor degradation, increased power losses, and voltage instability. This study aims to analyze the use of Static Compensator (STATCOM) as a reactive power compensation solution in 20 kV distribution networks, with a focus on improving power factor, reducing power losses, and voltage staability. These challenges are relevant in Indonesia, where growing electricity demand and limited infrastructure exacerbate energy inefficiencies. The research methodology uses a quantitative approach based on simulation in MATLAB/Simulink. A simple distribution network model with one feeder (load 500 kW, 300 kVAR) is created, integrated with a STATCOM with a capacity of 300 kVAR. Simulations are carried out to compare conditions before and after the use of STATCOM at constant and fluctuating loads, measure power factor, power losses, and voltage profiles. The simulation results show that STATCOM improves the power factor from 0.857 to 1.0, reduces power losses by 26.5% (from 425.39 W to 312.50 W), and suppresses voltage drop from 24.51 V to 12.50 V. STATCOM effectively maintains voltage stability under disturbance conditions with a fast response (5-10 ms). However, the high initial cost indicates the need for economic optimization for practical implementation.

Abstract

Calibration of measuring instruments is an important aspect in ensuring the accu-racy and reliability of industrial production systems, including in the palm oil derivatives (CPO) processing sector. Digital scales play a crucial role in the weighing process of raw materials, semi-finished products, and final products. However, each calibration process is inseparable from measurement uncertainty that can affect the quality of production results. Where this study aims to analyze the level of measurement uncertainty in the calibration process of digital scales used in CPO derivative production units. The research method is carried out by collecting scale reading data with standard loading, calculating type A (statistical) and type B (non-statistical) uncertainties, as well as calculating com-bined uncertainty and expanded uncertainty in accordance with ISO GUM (Guide to the Expression of Uncertainty in Measurement). Thus, the results of the analysis show that the greatest uncertainty comes from the variation in readings (repeatability) and the tol-erance of the standard weights used. The combined uncertainty value obtained is within the range that meets the industrial calibration tolerance limit, but there are recommenda-tions for improving environmental control procedures during calibration to minimize fur-ther deviations.
