Abstract

Kali Kemiri Sentani frequently experiences flooding, particularly during periods of intense rainfall. Given the critical importance of flood risk mitigation, this study aims to analyze the water flow rate in Kali Kemiri and investigate the key factors influencing its dynamics. The research was conducted within the Kali Kemiri watershed in Jayapura Regency, focusing on a watershed area with a total study area of 1,640 m², mapped at a small scale across two measurement points. Flow rate measurements were performed at two locations along Kali Kemiri using the float method. The study recorded key hydrological parameters, including water depth, river width, and flow velocity. These data were utilized to calculate the volumetric flow rate at the designated measurement sites. This methodology provides a comprehensive understanding of the hydrodynamic factors affecting water flow, which is essential for assessing flood hazards in the region. The results indicate that the highest discharge rate was observed at the first measurement point, with an average flow discharge of 0.188 m³/s and a velocity of 0.52 m/s. In contrast, the second measurement point recorded a discharge of 0.115 m³/s with a flow velocity of 0.29 m/s. These findings suggest a direct correlation between flow velocity and discharge, wherein an increase in velocity corresponds to an increase in discharge. Furthermore, the study highlights that the flow rate is influenced by watershed area, watershed volume, and watershed slope, which collectively govern the hydrological behavior of the river system.

Abstract

Penelitian ini bertujuan untuk meningkatkan Keterampilan Proses Sains (KPS) peserta didik melalui penggunaan e-modul kimia berbasis budaya Papua pada materi reaksi reduksi dan oksidasi. Populasi dalam penelitian ini adalah seluruh peserta didik Kelas X IPA SMA YPPK Teruna Bakti Jayapura yang berjumlah 50 orang. Pengambilan sampel dilakukan menggunakan teknik purposive sampling berdasarkan pertimbangan tertentu. Penelitian ini dilaksanakan di Kelas X IPA SMA YPPK Teruna Bakti Jayapura dengan jumlah sampel 28 peserta didik menggunakan metode penelitian dan pengembangan (Research and Development) model ADDIE. Instrumen penelitian meliputi angket KPS, lembar observasi, wawancara, dan tes hasil belajar. Selanjutnya, data dianalisis secara deskriptif kuantitatif dan kualitatif. Hasil riset menunjukkan bahwa, rata-rata KPS sebelum menggunakan e-modul berada pada kategori kurang terampil dengan persentase 47,32%. Setelah implementasi e-modul, KPS peserta didik meningkat secara bertahap pada setiap pertemuan, yaitu 68,30% RPP 1 (kategori kurang terampil), 71,25% RPP 2 (kategori terampil), dan 80,54% RPP 3 (kategori terampil). Secara keseluruhan, rata-rata KPS mencapai 73% dengan kategori terampil. Peningkatan paling signifikan terlihat pada indikator mengajukan pertanyaan (81,25%) dan mengomunikasikan (82,14%) dengan kategori sangat terampil. Temuan ini menunjukkan bahwa e-modul kimia berbasis budaya Papua efektif dalam meningkatkan keterampilan proses sains peserta didik serta mampu menjadikan pembelajaran kimia lebih kontekstual, interaktif, dan bermakna.
