Abstract

The waters of Lake Limboto show a decline in water quality, characterized by a decrease in clarity. Environmental factors, such as wind speed and direction, play a significant role in influencing the dynamics and quality of lake waters. To understand the influence of wind on water conditions, a comprehensive hydrodynamic study is required. This study focuses on analyzing the hydrodynamic characteristics of Lake Limboto waters based on momentum flux and its implications for lake water conditions. Wind speed and direction measurements were conducted on seven ducks in Lake Limboto waters during the period of November 1-3, 2024. Data were collected in the morning, afternoon, and evening. The lake's hydrodynamic characteristics were determined using formulas from the measured data. Hydrodynamic characteristics were interpolated using IDW cross validation leave one out and optimized with rank and neighboring point parameters. Wind direction was interpolated using IDW and converted into a vector field using Vector Field Layer Manager. It was found that the momentum flux by wind in Lake Limboto waters has a value range of 0-0.05 N/m2, and cross validation produced an RMSE of 0.003-0.01 N/m2. The interaction of momentum flux from wind and river flow causes sediment to be deposited in the coastal area of ​​Lake Limboto.

Abstract

One important parameter that needs to be considered in water quality is the acidity level (pH) in the water. This study aims to design and determine real-time and accurate pH sensor based on internet of thing (IoT). This system design uses an ESP32 microcontroller and The PH-4502C pH Meter Module sensor. The ESP32 can be connected to the IoT-based Blynk platform, allowing pH data to be monitored in real time via a smartphone. Testing of the IoT-based pH sensor was conducted to evaluate the system's real-time operation under varying distances. Meanwhile, the pH sensor's accuracy was determined by comparing its output with a digital pH meter using buffer solutions at different pH levels. The test results show that the time value required in each range is always constant, namely 1 s. This proves that IoT-based monitoring does not affect the range. Meanwhile, measurement of pH level was the average error value is 3.49%, and the sensor accuracy is 96.51%. These results indicate a low error rate, resulting in high accuracy. The sensor error value of 3.49% is lower than the specified error tolerance limit of <5%. This proves that the pH sensor, with an accuracy of 96.51%, is suitable and reliable for measuring pH in solutions.

Abstract

The Community Empowerment Program of Payunga Village in Processing Nile Tilapia (Oreochromis niloticus) into Snack Products to Increase Community Income was implemented as an effort to enhance the local economy through innovation in fishery product processing. Payunga Village has abundant tilapia resources; however, they have traditionally been used only as fresh food without further processing. This community service program aimed to improve local residents’ skills in processing tilapia into value-added products, specifically tilapia pempek, while also strengthening managerial capabilities and expanding marketing access through digital promotion. The implementation method included forming community and student groups, conducting technical training on tilapia processing, providing business management assistance, and introducing digital marketing strategies. The results showed significant improvement in participants’ production skills, entrepreneurship motivation, and awareness of product quality. The tilapia pempek product was well received by local consumers due to its unique flavor and affordable price. Furthermore, the program fostered community awareness of the importance of business diversification and the potential of creative rural economies. Overall, this program contributed to increasing income, strengthening family economies, and promoting sustainable local-based economic independence.

Abstract

A resistivity meter can find out resistivity depth of rock structure, sediment layer, or the depth of water surface. However, the resistivity meter that is often used requires manually recording of the measurement results before inputting them into the processing data software, and this creates many steps in the geoelectric survey. This is because acquiring a resistivity meter with a data storage system entails additional costs, due to its expensive price. Consequently, many of the resistivity meters currently found in laboratories or used in the field are not equipped with a data storage system. This research aims to design a resistivity meter with a data storage system for measurement results, based on Arduino Mega 2560, for laboratory scale. The used sensors were INA219 currents sensor and voltage sensor. In addition, the tests were carried out to determine the level of accuracy of each sensor and testing for data storage system of measurement result. This research employed Schlumberger configuration in the development of resistivity meter. This research has successfully developed a resistivity meter device with a current sensor accuracy level of 97.28% using the INA219 sensor, and a voltage sensor accuracy level of 97.44%. It is noteworthy that the accuracy level is high, and the device is capable of performing readings effectively. This research has successfully designed a resistivity meter which has a measurement data storage.
