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

Tujuan dari penelitian ini, yaitu untuk mengetahui pengaruh model pembelajaran Problem Based Learning (PBL) berbantuan media pembelajaran interaktif terhadap literasi sains peserta didik. Penelitian ini merupakan penelitian kuantitatif dengan menggunakan metode quasi eksperimen dan dengan desain penelitian nonequivalent control group design. Teknik sampling yang dipilih adalah menggunakan purposive sampling berjumlah 36 peserta didik yaitu 20 peserta didik kelas XI-1 sebagai kelas eksperimen dan 16 peserta didik kelas XI-2 sebagai kelas kontrol. Hasil uji hipotesis untuk mengetahui pengaruh model pembelajaran Problem Based Learning terhadap literasi sains peserta didik, yaitu menggunakan uji Independent sample t-test dengan teknik insrumen pengumpulan data yang digunakan adalah tes, dari pengumpulan data diperoleh nilai Sig. (2-tailed) sebesar 0,006 ≤ 0,05 sehingga H0 ditolak dan Ha diterima, yaitu terdapat perbedaan kemampuan literasi sains peserta didik setelah diterapkan model pembelajaran Problem Based Learning pada materi suhu dan kalor berbantuan media pembelajaran interaktif. Berdasarkan data penelitian dan analisis penelitian maka diperoleh nilai rata-rata pretest kelas eksperimen yaitu kelas XI-1 senilai 27,81 dan nilai posttest yaitu 81,35, sedangkan kelas kontrol yaitu kelas XI-2 memiliki rata-rata nilai pretest senilai 26,30 dan nilai posttest yaitu 69,92. Dapat disimpulkan bahwa terdapat signifikansi pengaruh model pembelajaran Problem Based Learning dibandingkan dengan model pembelajaran Direct Instruction
