Abstract

The water quality of drilled wells in the tourist area of Bantayan village, North Aceh, has been carried out. This study aims to find out how suitable the water from the drilled well is for use by the community in the area. Samples were taken from five water sources of drilled wells with a depth of 3.5 m located in Bantayan village. The feasibility of water consumption can be assessed by testing the quality based on microbiological, physical, and chemical parameters. The parameters measured were color, turbidity, odor (physics), heavy metal content pH (chemical), and bacterial content (microbiology). The measurement results showed that although almost all water samples had water quality that met the standards based on physical and chemical parameters, the water sourced from the five borewells did not meet the standards of biological tests. Testing revealed the presence of total coliform and Escherichia coli (E. coli) ranging from 8-370 CFU/100 mL and 0-150 CFU/100mL, respectively. According to the requirements of the Regulation of the Minister of Health of the Republic of Indonesia No. 2/MENKES/2023 concerning drinking water quality, the acceptable levels for total coliform and E. coli in drinking water are 0 CFU/100mL. Therefore, the presence of these contaminants in the drilled well water renders it unsuitable for consumption, posing potential health risks to the community.

Abstract

This study aims to identify the misconceptions of 10th-grade students of a Senior High School (SMA N 1) Ciawi Bogor on chemical bonding by using a two-tier diagnostic test consisting of nine questions. The research method that was carried out was quantitative research with adescriptive approach. The participants of this study were classes X-2, X-4, and X-8 of SMAN 1 Ciawi in the academic year 2023/2024, with a total sample of 96 students taken from three classes using purposive sampling. Moderate misconceptions concerning ionic bonding have been discovered in the responses provided by the students for questions 1 and 2, with percentages of 37.50 and 34.38%, respectively. In Question 3, which covered lattice and intermolecular forces on silicon carbide, misconceptions among students were found to be 72.92%, indicating a high level of misconception. The percentage of students experiencing misconceptions about ionic bonding in question 4 (58.33%) was considered moderate. Students' misconceptions about bonding and intermolecular forces on magnesium oxide were determined to be relatively low, at 30.21%. Students who experienced misconceptions about the conductivity of graphite (Question 6) were 43.75%, which can be categorized as moderate misconceptions. In Question 7 about sulfur, student misconceptions were observed at 15.63%, but there were 47.92% who did not have prior knowledge about sulfur as a simple molecular compound. When asked about the differences in intermolecular forces on water and hydrogen sulfide, the percentage of students who had misconceptions was observed at 50.00%, then on the concept of lattice and intermolecular forces on macromolecules at 25.00%. These results are also influenced by students' prior knowledge of macromolecules, which is quite limited. Teachers and educators can employ some potential futuristic instructional methods to help students understand chemical bonding more efficiently, such as implementing VR and AR simulations, integration of gamification and game-based learning, andvirtual field trips and interactive demonstrations.

Abstract

Low student learning outcomes are often caused by limited student participation and the use of teacher-centered learning approaches. This study aims to determine the effectiveness of the Think Pair Square (TPSq) cooperative learning model assisted by stick media in improving student learning outcomes, particularly in the topic of chemical compound nomenclature. The research used a pre-experimental one-group pretest-posttest design with participants from class X-10 students at a senior high school (N=32). Learning outcomes were measured using tests given before and after the implementation of the model. Data were analyzed using a non-parametric Wilcoxon test. The results indicated a significant improvement in student learning outcomes, with an N-Gain score of 0.71 (high category) and an effect size of 3.85 (very strong category). The TPSq model, supported by stick media, encouraged students to think, discuss, and share ideas actively, leading to a deeper understanding of the material. In conclusion, the stick media-assisted TPSq learning model is effective in enhancing student learning outcomes in chemical compound nomenclature.
