Abstract

Exposure to ultraviolet-B (UV-B) light contributes to a decrease in skin collagen levels, which can cause premature aging. This study aims to evaluate the effectiveness of telang flower (Clitoria ternatea L.) extract lotion in maintaining collagen levels and epidermal thickness of UV-B-exposed rat skin. A total of 30 Wistar male white rats (200-250 g) were divided into six treatment groups: negative control (distilled water), positive control (Vaseline), and four treatment groups of telang flower extract lotion with concentrations of 0.2, 0.5, 0.75, and 1%. Mice were exposed to UV-B light (311 nm, 70 mJ/cm² per session) for 14 days with a total dose of 420 mJ/cm². The lotion was applied twice daily, before and after UV-B exposure. Evaluation was performed by measuring collagen content and epidermal thickness using histology staining. Statistical analysis used One-Way ANOVA or Kruskal-Wallis if assumptions were not met. The results showed that the treatment group with telang flower extract significantly increased collagen content and epidermal thickness compared to the negative control (p < 0.05), with a dose of 0.5% showing the highest effectiveness. In conclusion, telang flower extract lotion has potential as a photoprotective agent against UV-B-induced skin damage.

Abstract

This research aims to research and develop (R&D) flipbook teaching materials based on the problem-based learning model for Class V Light materials. The development model used is Borg and Gall. Data were obtained by test and non-test methods. The test method is derived from the results of the pretest and posttest, while the non-test method is derived from the results of questionnaires, data, observations, interviews, and documents. The subject of the trial is a student of class V. In this research, media validators gave an average percentage of 90% product validation assessments, while material validators gave an average percentage of 93.33%. Both categories are considered very feasible. Both the pretest and posttest results for the student indicate progress. This is demonstrated by the 42.43 average difference between the pretest and posttest as well as a high N-Gain of 0.8106.  Since the obtained N-Gain is greater than 0.70, it is regarded as high. From the improvement in student learning outcomes, it can be concluded that the use of flipbook teaching materials in class V light materials can improve student understanding.

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

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.
