Abstract

The implementation of automated plant watering systems in the agricultural sector utilizes sensor technology based on the Internet of Things (IoT). This study aims to evaluate the performance of soil moisture and temperature sensors utilizing the IoT in an automated plant watering system. The sensors used are the YL-69 sensor to determine soil moisture and the DS18B20 temperature sensor to determine soil temperature. Both sensors are connected to the NodeMCU ESP8266 microcontroller. Testing was conducted from 07:00 to 17:00 WITA, with a 1-hour interval for data collection, monitored using the IoT on the blink application on the cellphone. Then, the data obtained is analyzed to determine the values of error and accuracy. The results obtained on the soil moisture sensor have an average error of 0.989% with an average accuracy of 99.011%. Meanwhile, the results obtained on the soil temperature sensor have an average error of 1.240% with an average accuracy level of 98.760%. The lower the error value, the better the sensor performance indicates the sensor's ability to read data that is close to the actual value of the comparison tool. Likewise, the higher the level of sensor accuracy, the better and more reliable the sensor is when used in an IoT-based soil temperature measurement system. This value indicates that the sensor's performance has a very high level of reliability and precision in detecting soil moisture and temperature in real-time. This system can be applied in agricultural technology education and vocational training programs.

Abstract

The increasing need for electrical energy due to technological growth requires using sustainable alternative energy sources. One potential energy source is solar energy, which can be converted into electricity through a thermoelectric generator (TEG). This study aims to design an optimal TEG configuration in converting heat from zinc roofs into electricity and to analyze the effect of variations in the shape of zinc roofs on the electrical power generated. The method used is an experiment with variations in the type of zinc roof, e.g. plate, wave, and box, and the TEG circuit configuration, e.g series and parallel. Measurements were made on the temperature, voltage, current, and electrical power generated, both with and without supercapacitors as energy storage. The results showed that zinc plates with a parallel configuration produced the highest electrical power of 0.01372 W, compared to zinc boxes and wave zinc. The parallel configuration proved to be more efficient than the series configuration. In addition, using supercapacitors also increases the electrical power generated and allows for greater energy storage.

Abstract

The Gorontalo region is located in an active tectonic zone, so it has a high level of seismic activity. Understanding the geometry of the subduction zone in this region is important for assessing earthquake hazards and disaster mitigation efforts. This study models the angle and depth of subduction of the subduction plate beneath the surface of the Gorontalo region using earthquake data from the USGS catalog from 1994 to 2024. The analysis was carried out using the vertical section method (cross-section), which divides the study area into three segments, namely A, B, and C. Each segment was analyzed using polynomial regression to determine the subduction pattern. The results show that the megathrust zone is at a depth of < 50 km, while the Benioff zone reaches up to 300 km. The obtained subduction angles are 49.01°-59.09° in Segment A, 6.49°-71.76° in Segment B, and 19.87°-58.15° in Segment C. These results show variations in subduction geometry that reflect the tectonic complexity of the Gorontalo region.

Abstract

This study aims to identify the type and thickness of sediment in Lake Limboto using the Schlumberger configuration geoelectric method. This method was chosen because of its ability to detect resistivity variations that reflect the characteristics of subsurface sediments. The research procedure begins with an initial survey to determine strategic measurement locations, followed by electrode arrangement and resistivity measurements. Data obtained from the measurements were analyzed using geophysical analysis software to produce a resistivity distribution model. The results showed that there were variations in sediment types, including sand, clay, and alluvial soil, as well as varying sediment thicknesses in various locations. These findings are expected to provide useful information for water resource management and mitigation of shallowing problems in Lake Limboto.

Abstract

The Gorontalo region is one of the regions on the island of Sulawesi that is quite significant in terms of tectonic activity due to earthquakes. This is because Gorontalo is located in a tectonic environment, with a subduction zone in the Sulawesi Trench north and the Balantak Thrust and Batui Thrust south of the Gorontalo Fault. To further understand Gorontalo's seismic activity, we conducted a seismotectonic analysis in the form of identifying the number of earthquakes from 1994 to 2025, interpreting the results of the focal mechanism distribution by classifying them in the Kaverina diagram, and analyzing the results of earthquake hypocentre relocation from 2015 to 2022. The study results show that 2.317 earthquake events over 30 years spread across all areas of Gorontalo, categorised as shallow, medium, and deep earthquakes. The Gorontalo area is dominated by reverse faulting focus mechanisms, which are commonly found at shallow to intermediate depths. This is interpreted as being due to the presence of a subduction zone. A different situation occurs at deep depths, where the focal mechanism is normal faulting, indicating the presence of extensional forces due to the rollback slab process. The distribution of earthquake mechanisms also shows that a combination of strike-slip and reverse mechanisms occurs around active fault zones. In contrast, strike-slip mechanisms with standard mechanisms are more dominant in extensional zones.
