Abstract

Ikan lele merupakan salah satu ikan yang hidup di air tawar yang sudah banyak dibudidayakan oleh masyarakat luas terutama di indonesia. Berkembangnya pembudidayaan ikan lele dikarenakan ikan lele dapat dibudidayakan di lahan yang kecil sekalipun seperti menggunakan terpal dan sumber air yang terbatas. Penelitian ini dilakukan bertujuan untuk mengetahui kendala dan masalah pada kegiatan usaha budidaya pembenihan ikan, sehingga dapat di tentukan strategi guna mengembangkan usaha budidaya ini. Penelitian dilakukan di Jl. Rasmi, Desa Bangun Sari, Kecamatan Tanjung Morawa, Kabupaten Deli Serdang, Kota Medan, Provinsi Sumatera Utara. Adapun metode penelitian yang digunakan dalam kegiatan ini menggunakan metode kulitatif, dimana teknik pengumpulan data menggunakan teknik observasi, wawancara dan dokumentasi yang dilakukan langsung ke desa bangun sari. Adapun hasil data yang diperoleh yaitu terdapat dua jenis ikan yang dibudidayakan pembenihannya yaitu jenis ikan lele pyton dan mutiara. Dari hasil penelitian yang dilakukan ini dapat disimpulkan bahwa penyusunan proses juga harus di perhitungkan dalam sebuah usaha terlebih lagi dalam usaha budidaya perikanan.

Abstract

Background: The 2022 PISA assessment reveals that Indonesian students demonstrate considerably weak science problem-solving abilities, achieving merely 383 points compared to the OECD's 485-point benchmark, with this deficiency particularly pronounced in biology education where learners encounter difficulties comprehending and contextualizing concepts such as the excretory system in practical scenarios. Methodology: Employing a 4D developmental framework (Define, Design, Develop, Disseminate) truncated at the Develop phase, this investigation created a STEM-integrated student worksheet designed to strengthen problem-solving competencies among eleventh-grade pupils, utilizing expert validation, stakeholder feedback surveys, and pre-post assessment protocols analyzed through percentage calculations, N-Gain coefficients, and paired-samples t-testing. Findings: The intervention demonstrated exceptional validity with 90% expert approval ratings across content and pedagogical dimensions, exhibited strong practicality reflected in 88.71% positive educator-student reception, and yielded statistically significant learning gains as evidenced by paired t-test results (p < 0.05) alongside a substantial N-Gain value of 0.75. Contribution: This study provides specific empirical evidence that a STEM-integrated student worksheet, developed through an adapted 4D model, effectively strengthens eleventh-grade students’ science problem-solving abilities in the excretory system Learning. The results further contribute to the field by establishing this worksheet as a valid, practical, and statistically proven instructional alternative that aligns with competency-based demands and improves analytical reasoning more effectively than conventional learning materials
