Abstract

Percobaan dilakukan pada bulan Maret sampai Agustus tahun 1997, di lahan sawah di desa Kranjingan, kecamatan Sumbersari, kabupaten Jember. Tujuan penelitian untuk mendapatkan kultivar dan galur harapan tembakau Kasturi yang mempunyai potensi hasil dan mutu tinggi. Perlakuan terdiri atas tujuh galur harapan (S.2153/1/12, S.2153/1/11, S.358/2/3/11, S.2156/1/3, S.358/1/10/4/ 1/1, S.2293/1, S.2155/1/7/1); dan empat kultivar dari koleksi plasma nutfah (Kasturi Ledokombo, Kasturi Mawar, Kasturi, dan Kasturi Bentoel), sebagai pembanding adalah kultivar Jepun (yang berkembang di petani). Perlakuan disusun dalam rancangan acak kelompok yang diulang tiga kali. Dari hasil pengujian didapatkan tujuh genotipe yang lebih tinggi hasilnya dibandingkan dengan Jepun yaitu: Kasturi Ledokombo (1.77 ton ha-1), S.2153/1/12 (1.75 ton ha-1), S.2153/1/11 (1.67 ton ha-1), S.358/2/3/11 (1.66 ton Ha-1), Kasturi Mawar (1.65 ton ha-1), S.2156/1/13 (1.63 ton ha-1), S.2155/1/7/1 (1.57 ton ha-1). Indeks tanaman genotipe yang lebih tinggi dari Jepun adalah: Kasturi Ledokombo (144.23), S.2153/1/12 (140.35), S.2153/1/11 (134.72), S.358/2/3/11 (133.16), Kasturi Mawar (131.42), S.2156/1/13 (124.95).

Abstract

This study aims to develop PhET-based student worksheets (LKPD) and examine their effectiveness in improving students’ cognitive learning outcomes at MTs Nur Hadi Muara Jawa. The research employed a research and development (R&D) design using the ADDIE model, consisting of analysis, design, development, implementation, and evaluation stages. The subjects of the study were MTs students selected through purposive sampling. Data were collected using expert validation sheets, student response questionnaires, and cognitive achievement tests administered before and after the implementation of the worksheets. The data were analyzed using descriptive statistics and inferential analysis to measure learning gains. The findings indicate that the PhET-based LKPD are valid, practical, and effective in enhancing students’ cognitive performance, particularly in understanding abstract scientific concepts. The integration of interactive simulations encourages active learning, inquiry processes, and conceptual understanding. Therefore, PhET-based student worksheets can serve as an effective instructional material to support digital-based science learning in secondary education.
