Abstract

Budidaya ikan lele mutiara (Clarias gariepinus) berkembang pesat di Indonesia karena pertumbuhannya yang cepat, efisiensi pakan tinggi, dan ketahanan terhadap lingkungan. Meningkatnya permintaan mendorong pembudidaya untuk memilih pakan yang tidak hanya menunjang pertumbuhan tetapi juga menjaga kualitas air. Penelitian ini bertujuan menganalisis pengaruh kandungan pakan komersial berbeda terhadap kualitas air budidaya benih ikan lele mutiara. Penelitian dilakukan secara eksperimental menggunakan Rancangan Acak Lengkap (RAL) dengan empat perlakuan pakan (A: kontrol; B: protein tinggi; C: protein sedang; D: protein rendah) dan lima ulangan. Parameter kualitas air yang diamati meliputi suhu, pH, oksigen terlarut (DO), total zat terlarut (TDS), dan kadar amonia (NH₃), yang diukur selama 4 minggu. Hasil uji ANOVA menunjukkan bahwa jenis pakan komersial berpengaruh signifikan terhadap parameter pH, TDS, DO, dan amonia, namun tidak terhadap suhu. Uji lanjut Tukey HSD menunjukkan bahwa pakan berprotein tinggi paling optimal menjaga kualitas air, ditandai dengan kadar oksigen terlarut (DO) tinggi dan kadar amonia rendah. Sebaliknya, pakan berprotein rendah memicu peningkatan kadar amonia, TDS, dan pH yang berisiko bagi lingkungan budidaya.

Abstract

The main problem is the lack of dedicated digital e-modules in the high school biology curriculum analysis course, causing students to rely solely on government  documents and online sources. This research aims to develop a TPACK-based e-module enriched with microlearning strategies and test its feasibility through expert validation and user readability testing. The research uses a research and development method with the ADDIE model, which includes the stages of needs analysis, design, development, limited implementation, and evaluation. The research subjects involved three experts (content, media, and language) and student at Universitas Negeri Jakarta, classes of 2022 and 2023, who had completed the Biology Curriculum Review course. Data was collected with experts’ and users’ feasibility questionnaires, then analyzed using feasibility criteria. The result show that according to the experts review, the percentage is about 95.50% (very feasible) and according to the respondent is about 88,29% (very feasible). The e-module was highly feasible but requires improvements in design consistency, language clarity, and integration of TPACK and microlearning for greater effectiveness.
