Abstract

Bukit Tangkiling di wilayah administrasi Kecamatan Bukit Batu Kota Palangka Raya merupakan wilayah yang berbukit dan dibentuk oleh batuan granit yang resisten terhadap erosi. Batuan granit merupakan batuan beku dalam plutonik yang bersifat asam dan mengandung unsur logam. Perubahan pola hidup masyarakat Kota Palangka Raya semakin hari semakin  modern, sehingga kebutuhan akan air bersih dan air minum sangat tergantung dengan air isi ulang yang murah dan praktis. Metode pemilihan lokasi sampling untuk penelitian ini menggunakan metode purpose sampling dan analisis menggunakan metode matching dengan Permenkes No. 492/Menkes/Per/IV/2010. Lokasi pengambilan sampel sumber air Tangkiling untuk pengukuran lapangan dan pengujian laboratorium diambil pada wilayah Bukit Tangkiling yang berdekatan dengan tubuh batuan granit. Penelitian ini mengambil 3 (tiga) lokasi titik sampling dan dibagi menjadi 3 (tiga) pengukuran kualitas lapangan dan 3 (tiga) sampel untuk analisis laboratorium. Kualitas Kimia air hasil pengukuran lapangan dengan nilai rata-rata pH 4,42; TDS 13,67 mg/l; EC 28,67 µS/cm, suhu 25,90ºC dan salinitas 0%. Hasil laboratorium untuk kualitas air rata-rata nilai NO3- 3,71 mg/l; NO2- <0,005 mg/l; Cr6+ <0,007mg/l; Fe terlarut <0,041 mg/l; F- <0,019 mg/l; dan Zn terlarut <0,06 mg/l. Dari 11 (sebelas) parameter pengukuran dan pengujian kualitas air sumber air Tangkiling menunjukkan 10 (sepuluh) parameter sesuai dengan baku mutu kualitas air minum dan 1 (satu) parameter belum memenuhi baku mutu Permenkes 492/2010. Batuan granit di Bukit Tangkiling dari sampel air yang diuji hanya berpengaruh pada parameter pH, dan perlu adanya pengolahan air minum untuk meningkatkan pH air agar sesuai standar air minum sebelum dikonsumsi.

Abstract

English songs are widely used as informal learning resources and may influence students’ language development through both linguistic exposure and affective engagement. This study aims to investigate students’ perceptions of the influence of listening to English songs on their language skills in the English Education Study Program at the University of Palangka Raya. The study employed an explanatory sequential mixed-methods design. Quantitative data were collected through a questionnaire administered to seventh-semester students from the 2022 cohort(N=50). The instrument was tested for validity and reliability using Cronbach's alpha before being analyzed through descriptive statistics. Based on the quantitative results, ten students (N=10) were purposively selected for semi-structured interviews to gain deeper insights. Interview data were analyzed using thematic analysis. Quantitative findings reveal that 94% of students had positive perceptions, while 6% reported negative views regarding the use of English songs in language learning. Qualitative results revealed that listening to English songs supported vocabulary development, listening comprehension, pronunciation, speaking confidence, and overall language improvement. However, some students viewed songs primarily as entertainment and reported challenges, including distractions, exposure to informal language, and mismatches with their learning preferences. Overall, the study indicates that English songs can serve as a beneficial supplementary medium for language learning, depending on learners’ preferences and the extent of instructional integration.
