Abstract

The utilization of microcontroller systems for monitoring water quality in aquaculture remains uncommon. Particularly, there is a pressing need for real-time monitoring of water quality to ensure optimal control in aquaculture operations. Hence, this research aims to assess the performance of an Arduino-based water quality monitoring system that has been developed. This system employs various sensors to monitor water quality and is centered around an Arduino microcontroller. Subsequently, the constructed system underwent testing using different solutions, including TDS solution calibrated to 1382 ppm, pH buffer solutions of pH 4.00, pH 6.86, and pH 9.00, as well as clean water and water from fish ponds. The measurement results obtained from the device were compared and analyzed for error rate, precision, and accuracy. The findings indicate that the system functions effectively with temperature, TDS, and pH sensors, exhibiting favorable error, accuracy, and precision values. Thus, the Arduino-based water quality monitoring system devised in this study proves to be a viable option for aquaculture operations. This research contributes novel insights into real-time water quality monitoring, enhancing the efficiency of water management in aquaculture.

Abstract

The production of complex machine components requires advanced and accurate techniques. Achieving optimal quality through 3D printing involves carefully examining the process parameters. However, many studies have not thoroughly explored the impact of these parameters on parts produced using Fused Deposition Modeling (FDM) 3D printing. This study evaluates how process parameters and material variations affect the dimensional accuracy of printed parts. The study focuses on input variables such as material type, infill density, infill pattern, and raster angle. Using the fractional L9 Taguchi method, the optimal settings identified were PLA+ material, 80% infill density, an infill grid pattern, and a 0° raster angle, resulting in a 1.39%-dimensional deviation and an S/N ratio of -3.29 dB. ANOVA analysis reveals material type as the most significant factor, contributing 49.81% to performance. These findings, complemented by statistical analyses, can guide decision-making in industrial applications and serve as a reference for selecting FDM 3D printing settings related to dimensional accuracy to print components in the industry.

Abstract

Monitoring of diesel engine operational performance on fishing vessels recorded in real time based on microcontrollers is still rarely used. Monitoring of diesel engine operations is important to ensure the engine is in optimal performance as well as a consideration for predictive maintenance actions. This study aims to design and implement a real-time monitoring device based on microcontrollers. This device can measure and record RPM, temperature, and pressure data on diesel engines with good accuracy. Hall effect sensors for RPM, DS18B20 for temperature, and piezoresistive sensors for pressure are used, to maintain the right time it is equipped with RTC, SD card module for data storage, and Wi-Fi module for data access via the web. The test results show that this device is able to measure with good accuracy on each parameter with an average error of below 2%. When the operational parameters exceed the predetermined threshold, the device successfully gives an alarm as a critical sign. This study makes a significant contribution to the management and maintenance of diesel engines with real-time data and wireless access that increases efficiency and minimizes downtime due to operational failures

Abstract

This paper presents the model and performance of a portable solar power generation system designed specifically for the electricity needs of fishermen. The objective of this study is to evaluate the performance of the portable solar generator under various environmental conditions. The outline of this paper includes the design process, fabrication, and testing conducted under three different weather conditions. The main components of the system consist of photovoltaic (PV) modules, enclosures, batteries, solar charge controllers, inverters, and other supporting components. The three weather conditions examined during testing are uncertain bright rain, clear bright conditions, and heavy rain. The assessment focuses on environmental parameters, power output, and the efficiency of the portable solar generator. The results indicate that weather conditions significantly impact environmental factors such as solar radiation and ambient temperature, which are essential for effective natural cooling of module. The maximum output power of this solar panel generator system is 60,05 watts, with an efficiency of 13%. This system is designed to meet the operational needs of fishermen, with a portable design that facilitates their activities.
