Abstract

This research aims to determine the improvement of students' cognitive learning outcomes in geography through the application of essay evaluation questions on lithosphere materials. Data collection was carried out from January-February 2023, at SMAN 61 Jakarta. The research method used by the researcher is a quantitative method with true experimental approach, and pretest-posttest control group design, where the researcher acts as a teacher in class, assisted by subject teachers as collaborators. The instrument used is a formative test on lithosphere material in the form of essay questions consisting of 8 questions. The results show that the application of evaluation questions through essay form in improving students' cognitive learning outcomes in geography has a varied range of measurable cognitive level results, from C1 to C6. Students have freedom to express their thoughts and explore in choosing answers, which allows for a broader and more complex measurement of cognitive thinking abilities.

Abstract

This study aims to determine the cognitive learning outcome of the visual, auditory, kinesthetic learning model on eleventh-grade social studies students' in disaster mitigation material at SMA Negeri 1 Jakarta during 2022/2023 academic year. Using a quasi-experimental method with a pretest & posttest control group design, the sample population selected through cluster random sampling, comprises 33 students in control group and 35 students in experimental group. The research instrument consists of 20 items multiple-choice test. The results shows that students learning with the visual, auditory, kinesthetic approach improved significantly, from 57.28 to 77—an increase of 19.71. Meanwhile, those with a cooperative learning method saw a smaller increase, from 57.12 to 64.55—an increase of 7.42. The Independent Sample t Test produced a Sig.(2-tailed) value of 0.001, rejecting null hypothesis and accepting alternative hypothesis. In conclusion, implementing Visual, Auditory, Kinesthetic model positively impacts students' learning outcomes in disaster mitigation material.

Abstract

This study aims to analyze the level of Escherichia coli (E. Coli) contamination in groundwater in Bidara Cina Sub-district East Jakarta an area characterize by high population density and frequent flooding. The research employs a quantitative descriptive method utilizing Landsat 8 satellite imagery and the Normalized Difference Built-up Index (NDBI) to assess building density alongside laboratory testing of 22 groundwater samples. The findings reveal that five samples were contaminated with Escherichia coli (E. Coli) with the highest concentration reaching 18,2/100 ml in RT 02 RW 07 – an area located very close to the Ci Liwung River and marked by extremely dense housing. Contributing factors to the contamination include recurrent flooding, poor sanitation, and domestic wastewater discharge into the river. Although located farther from the river, RW 16 also exhibited contamination due to unsanitary condition in the public housing complex. All contaminated samples exceeded the quality threshold ser by the Indonesian Ministry of Health Regulation No. 2 of 2023. These results highlight the urgent need for strengthened groundwater quality monitoring and the provision of safe altenative water sources for affected communities.
