Abstract

This research has been conducted with the aim of simulating the process of seawater intrusion using SEAWAT software and assessing the factors causing seawater intrusion. In this simulation, variations in hydraulic conductivity and aquifer material types are explored to understand their impact on the distribution of water levels. The simulation results are presented in the form of simulated concentration plots used to visualize concentration distribution with color gradients reflecting changes in concentration values. Additionally, the direction of groundwater flow is represented by arrows, aiding in understanding the movement patterns of dissolved substances within the aquifer. Simulated head plots are created using colors and contour lines. The resulting simulated head plots depict changes in color and contour lines that represent variations in water levels throughout the aquifer. Color gradients from yellow to purple indicate a decrease in water levels, while contour lines indicate the direction of groundwater flow. Furthermore, changes in the shape of contour lines from straight to curved depict changes in the topography or hydrogeological characteristics within the aquifer. The simulations are carried out by considering changes in hydraulic conductivity and aquifer material characteristics. In the context of this research, hydraulic conductivity is considered a key factor influencing the movement of dissolved substances within the aquifer, and through this analysis, it is found that hydraulic conductivity significantly affects water level distribution and groundwater flow patterns.

Abstract

This study investigates the effectiveness of Problem-Based Learning (PBL) in improving the critical thinking skills of science education students in a biophysics course. The research employed a pre-experimental design using the One Shot Case Study method with posttest-only data. The participants were fourth-semester undergraduate students from the Science Education Study Program at the State University of Surabaya, who took the Biophysics course in the 2023/2024 academic year. The study was conducted in June 2023. Data analysis using the Shapiro-Wilk test showed a significance value of 0.086, indicating that the data were normally distributed. A one-sample t-test yielded a significance value of 0.417, which supports the conclusion that PBL has a positive influence on students’ critical thinking skills. Overall, the implementation of PBL in biophysics lectures demonstrates its potential to enhance critical thinking among science education students.

Abstract

Salt is an essential commodity for both domestic use and industrial applications, with East Java Province in Indonesia playing a crucial role in national salt production. Traditional salt production methods, primarily based on natural evaporation, face challenges due to seasonal factors, particularly during the rainy season. This study investigates the environmental conditions affecting the salt crystallization process in the Greenhouse Salt Tunnel (GST) technology. Field experiments were conducted at two sites, Tuban Regency on the North Coast and Malang Regency on the South Coast, where key parameters such as air temperature, water temperature, humidity, wind speed, and evaporation rates were monitored three times daily. The findings showed that water temperatures within the GST ranged from 31 to 38°C on the North Coast and 26 to 38°C on the South Coast. Wind speeds varied between 1.5–2.4 m/s on the North Coast and 0.4–1.0 m/s on the South Coast, while humidity levels ranged from 54 to 80%. The GST system achieved a salt production rate of 6.4 kg/m² with NaCl content exceeding 94%, a significant improvement over traditional methods, which yield less than 70% NaCl. These results demonstrate that GST technology enhances both the quality and quantity of salt production, though design modifications are needed to address the dynamic coastal environment.

Abstract

The research explores the correlation between critical thinking skills and argumentation skills are still rarely found, especially in Biology lectures. Building an argument is actually a representation of students’ critical thinking skills and cognitive structure. This study investigates the correlation between critical thinking skills and argumentation skills among biology students exposed to RQA, ADI, WE-ARe, and conventional teaching strategies. The samples of this research were Biology education students in the fourth semester undergoing Animal Physiology. The data were analyzed by using regression analysis. Using regression analysis, significant correlation was only found in the ADI group (R² = 0.192, p < 0.05). These findings underscore the importance of using inquiry-driven models to enhance students' reasoning abilities. The results of this research are most likely affected by the students’ academic ability

Abstract

Covid-19 prevention has also entered a new era with the availability of the Covid-19 vaccine, which has undergone clinical trials and has been mass-produced to enhance immunity. However, the administration of vaccinations has resulted in unexpected reactions known as Adverse Events Following Immunization (KIPI). This phenomenon suggests that low vaccination rates may be associated with perceived dangerous KIPI reactions, which can be attributed to doubts and misinformation about vaccines. This study used a correlation analytical research design with a retrospective method. The population of this study consisted of all individuals who had received vaccination and experienced KIPI reactions in the working area of Teja Health Center, totaling 30 people. The characteristics of the respondents, as seen from their allergic history and vaccine stages, showed a significant correlation (p = 0.027 < 0.05). The p-value for vaccine stages was 0.000, indicating a significant relationship with the severity of KIPI reactions in Covid-19 vaccine recipients. However, age and gender were not significantly associated with the severity of KIPI reactions. The severity of KIPI reactions in Covid-19 vaccine recipients has a significant correlation with the characteristics of the respondents, as seen from their allergic history and vaccine stages.

Abstract

Base Transceiver Station (BTS) towers are highly vulnerable to lightning strikes. A lightning strike is a moving electric charge that generates an electric field and a magnetic field, both of which are vector quantities, and induces voltage around the tower. The closer to the tower, the greater the values of the electric field, magnetic field, and induced voltage generated. A 49-meter highs tower in Mataram City is located 25 and 300 meters from residential areas and public facilities. The metabolism of living organisms, such as blood circulation, nerve function, heart rate, lung function, cell growth, and cell division, are also vector quantities. Exposure of living organisms to external electric fields exceeding the threshold of ≥10 kV/m can disrupt their metabolism. It is crucial to determine the magnitude and direction of the electric field vector caused by lightning strikes on BTS towers and how it affects living organisms around the tower. Observations are based on Coulomb's Law and its derivative theories on electric fields. The peak lightning current in tropical areas ranges from 10 to 100 kA, with a frequency of 200 kHz. The electric field intensity at distances of 25 and 300 meters is 58.30, 584.50, 4.86, and 48.71 kV/m, respectively. These results indicate that a distance of 25 meters from the tower is not safe from exposure to high electric field intensity values.
