Abstract

The increasing energy demand in Indonesia encourages the exploration of alternative energy sources, including geothermal energy. Bondowoso Regency, particularly the Blawan area, holds significant geothermal potential that remains underutilized. This study analyzes the relationship between Land Surface Temperature (LST), Normalized Difference Vegetation Index (NDVI), and Land Use Land Cover (LULC) using Landsat 8 imagery processed through Google Earth Engine. Spatial data of LST, NDVI, and LULC were extracted, visualized, and interpreted to identify geothermal manifestation areas. The results show that geothermal manifestations are indicated by high LST values (above 35°C), low NDVI values (sparse vegetation), and specific land use patterns, especially in the northeastern part of Bondowoso. The integration of LST, NDVI, and LULC enables more accurate identification of geothermal potential. The study concludes that remote sensing-based analysis is effective for detecting geothermal manifestations and supports more optimal geothermal resource mapping, exploration, and management, contributing to the sustainable development of renewable energy in the region.

Abstract

The environmental issues caused by conventional plastic waste are becoming increasingly serious, driving the development of more eco-friendly bioplastics. This study examines the mechanical properties, solubility, and biodegradability of seaweed-based bioplastics with the addition of curcumin and anthocyanin as additives. The results indicate that bioplastics containing only anthocyanin exhibit the best tensile strength (3.78 ± 0.26 MPa) and elasticity (12.48 ± 0.49 MPa). In contrast, bioplastics containing only curcumin show the lowest mechanical properties. The addition of anthocyanin enhances tensile strength and elasticity through the formation of strong hydrogen bonds with seaweed polymers, whereas curcumin decreases mechanical properties due to less stable molecular interactions. In terms of solubility, anthocyanin recorded the highest value (72.04%), while curcumin had the lowest (37.61%) due to its lower water stability. Regarding biodegradability, the combination of anthocyanin (1.25%) and curcumin (3.75%), as well as pure curcumin (5%), showed the highest degradation rates, whereas a balanced mixture (2.5%:2.5%) exhibited the lowest biodegradability. In conclusion, anthocyanin improves the mechanical properties and solubility of bioplastics, while curcumin supports biodegradability. Seaweed-based bioplastics with added curcumin and anthocyanin show potential as eco-friendly antibacterial materials.

Abstract

This study aims to analyze the influence of the problem-based learning model on students' science literacy in science lessons in class V, especially on heat materials and their transfer. This study focuses on the pre-experimental method using a one-group pretest-posttest design research design. Data collection is carried out by providing tests consisting of pretest and posttest. Sampling technique through purposive sampling. The research sample amounted to 25 students. The data analysis technique was carried out by N­-Gain and T-paired sample t-test. Based on the calculation of the hypothesis test using the t-test, it indicates that there is a significant difference between the pretest and the posttest. This can be seen from the significance value (p) = 0.000 (p < 0.05) so that the H0 hypothesis is rejected. This illustrates that the implementation of the problem-based learning model has a positive influence on students' science literacy in science lessons. Furthermore, based on the average N-Gain value of 0.5241 located in the medium group, this result indicates that the implementation of problem-based learning model is effective in improving students' science literacy in science lessons. Thus, it is concluded that the problem-based learning model has positive influence on students' science literacy. This study will contribute to the development of effective learning strategies to optimize students' science literacy and provide recommendations for educators in the application of the problem-based learning model in elementary schools.

Abstract

This research explores the correlation between microplastic abundance and water quality parameters in Sendang Biru Waters, Malang Regency, focusing on two sampling locations: TPI Kondang Buntung and TNI Naval Post. Water samples were collected and analyzed for microplastics using Fourier-transform infrared spectroscopy (FTIR) to identify various polymer types. Statistical methods, including Spearman's correlation and Kruskal-Wallis tests, were employed to assess the relationship between microplastic presence and water quality indicators such as pH, dissolved oxygen (DO), total suspended solids (TSS), and biological oxygen demand (BOD). The results show significant correlations between microplastic abundance and water quality parameters. The correlation coefficient for pH was -0.823 (p < 0.05), indicating an inverse relationship between microplastics and pH. For DO, the correlation coefficient was -0.612 (p < 0.05), suggesting that higher microplastic concentrations are associated with lower oxygen levels. TSS showed a correlation coefficient of 0.711 (p < 0.05), indicating a positive relationship. BOD revealed a coefficient of 0.794 (p < 0.05), suggesting higher microplastic abundance corresponds to greater organic pollution. The study highlights the impact of human activities, especially fishing and tourism, on microplastic pollution and its potential effects on marine ecosystems and human health. Additionally, the presence of microplastics in water bodies raises concerns about their role as carriers of toxic pollutants.

Abstract

Misconceptions must be addressed immediately because they can cause failure to achieve learning objectives. The purpose of this study was to identify misconceptions, determine the level of misconception categories in the concept of force, such as friction, spring force, and muscle force, and determine the science learning process in the material of force. This study has a uniqueness in the form of subjects used, namely schools participating in the Kampus Mengajar 7 program, where the literacy and numeracy conditions of students are relatively low. This study uses a qualitative approach, with research subjects being students and teachers of grade IV at one of the elementary schools in Blitar City. The data collected include the results of the Three-Tier Diagnostic test to identify misconceptions, interviews with teachers, and documentation. Data analysis methods consist of data reduction, data presentation, and drawing conclusions. The results of the study showed that there were misconceptions in the material of force in science learning, especially in friction, spring force, and muscle force. Of the three concepts of force, there are still misconceptions in the material of force based on its type, such as spring force and friction having a high category and muscle force with a low category. These findings highlight the need for more hands-on experimentation and contextualized instruction in elementary science education to reduce misconceptions. Meanwhile, in the science learning process, teachers use a direct instruction model with a few experiments.

Abstract

: Improving catch data through the standardization of catch per unit effort (CPUE) is crucial in providing accurate information for fish stock assessments. This study aims to develop a CPUE standardization model for dolphinfish (Coryphaena hippurus) in the Southern Java Waters. The analysis is based on historical dolphinfish catch data collected between 2019 and 2023. Bias in the CPUE data was reduced using the generalized additive model (GAM) approach. The results indicate that all explanatory variables significantly influence CPUE standardization. The combination of fishing duration, location, and period parameters proved effective in standardizing CPUE. The GAM-based standardization method successfully reduced variability in nominal CPUE, producing more consistent data. These results can provide an essential scientific basis for developing a sustainable management strategy for the Indian Ocean dolphinfish.

Abstract

Education is a conscious and planned effort to create a learning and teaching atmosphere so that students actively develop their potential to have spiritual religious strength, self-control, personality, intelligence, noble morals, and the skills needed by themselves, society, nation and state. Education has a major role in achieving success in child development. Education is a process that is carried out consciously and planned in order to develop the abilities and potential that exist within a person. This study aims to see the effect of implementing the PBL model on students' learning activities and problem-solving abilities on the material of magnetic force in elementary schools. This study uses a quantitative approach with a quasi-experimental design with a pretest-posttest non-equivalent control group design. The results showed that the experimental group that implemented the PBL learning model experienced a significant increase compared to the control group that used conventional learning. The increase in learning activities in the experimental group was recorded at 22.39%, while the increase in problem-solving abilities reached 31%. In contrast, the control group that used conventional methods also showed an increase, but in a lower percentage, namely 20.11% for learning activities and 21.26% for problem-solving abilities. The application of the PBL model is more effective in improving both aspects compared to conventional learning methods.

Abstract

This study explores the influence of the marketing mix on consumer purchasing decisions for specialty organic coffee at Waroeng Kopi Kayumas in Situbondo Regency. It also examines how consumer attitudes and purchase intentions mediate this relationship. Using an accidental sampling method, data were collected from visitors at the café. The results indicate that while the marketing mix does not directly affect purchase decisions significantly, it has a strong and significant impact on consumer attitudes and purchase intentions. In turn, both these factors significantly influence purchasing decisions. Furthermore, the marketing mix indirectly affects purchase decisions through its influence on attitudes and intentions. These findings contribute to a deeper understanding of consumer behaviour, particularly in niche markets like organic products. They also offer practical and educational value providing a model that can be applied in teaching consumer decision-making, marketing strategies, and sustainability practices in agribusiness and entrepreneurship education
