Abstract

Cu2ZnSnS4 is a low-cost and environmentally friendly thin layer solar cell absorber material. The electrochemical deposition method is intended to study because it enables producing films with high homogeneity based on solution precursors. This research review focuses on examining the CZTS electrochemical deposition method in order to identify the effect of the sulfurization process (sulfurization temperature and time) so that the best electrochemical deposition process can be identified for future work of high-efficiency CZTS thin layer solar cell fabrication based on solution precursor. The results show that the Cu2ZnSnS4 layer deposited through the electrochemical method has a 1.4-1.6 eV bandgap range. The etching process to post-annealing 0.1M KCN is crucial to effectively and selectively remove CuS, ZnS, and Cu6Sn5 secondary phases.

Abstract

This research aims to validate the method of analyzing the concentration of coffee solution by measuring light absorbance using simple spectrophotometry. Spectrophotometry is a technique that utilizes the interaction between visible light and electromagnetic waves on a substance. Measurement of the absorbency of the coffee was carried out by making five samples of coffee solution with different concentrations, namely 100 ppm, 160 ppm, 200 ppm, 350 ppm and 400 ppm. Absorbance measurements were carried out at visible light wavelengths (380 750 nm). The validation of the coffee has good linearity with a correlation coefficient of 0.9818; 0.9902 and 0.9788. The average precision value for the three treatments was 0.0056% with a Limit of Detection (LOD) and Limit of Quantitation (LOQ) of 115 ppm and 383.33 ppm for (  405 nm 10); 44 ppm and 146.67 ppm for ( 532 nm 10); 70.2 ppm and 234 ppm for (  650 nm 10). This indicates that the validation result of absorbance analytical method of the coffee, using simple spectrophotometry is not different from the standard measurement.

Abstract

Indonesia produced a total of 3,203,775 tons of pineapples in 2022, generating approximately 4,024,800 kg of pineapple peel waste annually, which is then wasted. Therefore, this research aims to utilize pineapple peel waste as the main material for bio-batteries and employs Cu-Al electrodes. The objective of this study is to enhance the voltage and current of bio-batteries made from pineapple peel waste by maintaining the cells in a closed condition to reduce oxidation and using a denser electrolyte through the addition of NaOH and used battery electrolytes. This research employs an experimental method to determine the measurement values of voltage, current, power, light intensity, and bio-battery capacity. The research findings indicate that bio-batteries made from pineapple peel waste with the addition of NaOH and used battery electrolytes increase the maximum voltage and current by 181% and 100%, respectively, resulting in a power output of 36 mW and a light intensity of 540 lux. The best bio-battery capacity of 780 mAH is found in sample A3. Bio-batteries made from pineapple peel waste with the addition of NaOH and used battery electrolytes show potential as an alternative energy source.

Abstract

This research was carried out to find out the dynamics of climate change in the Bangka Belitung Islands, by utilizing BMKG observer station data at Depati Meteorological Station, starting in 1981 until 2022 that the official obtained from the BMKG website online. This research was conducted at the Education laboratory of FKIP Physics University of Sriwijaya. The research method used is secondary data research with a quantitative approach. Data analysis was used using the RClimDex application with the Expert Team on Climate Change Detection and Indices (ETCCDI) rules. Trend analysis was carried out with non-pithelmetry statistical tests Man-Kendall and Sens tests. The temperature indexes experience significant trends, which indicates that the longer the temperature in the Bangka Belitung Islands will increase.

Abstract

The purpose of this paper is to describe the essence that occurs at each stage in the discrepancy evaluation model which consists of the Design, Installation, Process and Product stages related to the Blended Learning method in the modern spectacles course at the Muslim University of Maros. Based on the type of research used, this research is included in program evaluation research using the discrepancy evaluation model. The research sample consisted of 14 people plus 1 modern physics lecturer. Data collection was carried out using a mixed method with data collection instruments using, (1) interview guidelines, (2) questionnaires with a Likert scale model and (3) documentation. The data analysis technique used for qualitative data is data analysis using the Miles and Huberman model. This data analysis technique consists of data collection, data reduction and drawing conclusions. As for the quantitative data, the data analysis technique used is quantitative descriptive analysis and the calculation of the coefficient of determination. The results showed that (1) there was no discrepancy in the design stage (2) there was a discrepancy in the installation stage of 0.04 (3) there was a discrepancy in the Process stage of 0.23 (4) there was a discrepancy in the Product stage of 0. 78. So that the Blended Learning lectures can be continued with suggestions for improvement, namely (1) Lecturers continue to carry out their obligations to carry out face-to-face lectures, (2) Require students to study material in Google Classroom, (3) Uploaded material has various forms.

Abstract

This study aims to assess the influence of blended learning, along with a guided inquiry-based tracker app, on students' ability to think creatively. The main goal of the study is to quantify the extent to which this approach enhances students' capacity for original thought. The research design employed in this study is the One Group Pretest Posttest design. The research sample consisted of thirty-six students from SMAN 1 Gedongtataan's X Science 3 class. The instruction of fundamental harmonic motion on springs is facilitated through the utilization of a guided inquiry-based tracker application in a blended learning environment. The collection of data on students' creative thinking abilities involved the use of written assessments (Pretest-Posttest) and the analysis of this data using the Paired Sample T-Test. The research findings showed an N-Gain value of 0.20, which falls into the low range. Additionally, the paired sample T-test analysis revealed a statistically significant result with a sig (2-tailed) value of less than 0.05. The findings indicate that there were discernible variations in the creative cognitive abilities of students prior to and following their utilization of the tracker application. The results indicate that the usage of a guided inquiry-based tracker application in blended learning environments can improve students' ability to think creatively.
