Tujuan penelitian ini adalah untuk mengetahui (1) pengaruh tinggi para-para terhadap produksi tanaman tomat; (2) relevansi implementasi model ekspemerimen ini pada proses pembelajaran hortikultura. Jenis penelitian ini adalah eksperimental, dengan menggunakan rancangan acak lengkap. Sampel penelitian dibagi menjadi dua kelompok, yaitu kelompok kontrol (P0) yang tidak diberi para-para dan kelompok eksperimen (P1, P2, P3 dan P4) yang diberi perlakuan berupa para-para dari bambu dengan tinggi masing-masing 40 cm, 60 cm, 80 cm dan 100 cm. Jumlah ulangan dilakukan sebanyak empat kali. Jumlah sampel pada masing-masing perlakuan 3 tanaman. Jumlah total tanaman tomat yang dipakai sampel adalah 5 X 4 X 3 tanaman = 60 tanaman. Data yang dianalisis adalah data berat basah buah tomat. Hasil analisis uji normalitas dan homogenitas menunjukkan data terdistribusi normal dan homogen. Sedangkan hasil analisis uji anova menunjukan adanya perbedaan yang signifikan. Selanjutnya hasil analisis uji lanjut dengan uji LSD atau uji BNT, menunjukan bahwa ada perbedaan yang signifikan antara berat basah buah tomat berdasarkan perlakuan di mana hasil terbaik diperoleh pada tanaman tomat dengan perlakuan P4 yaitu penanaman dengan para-para setinggi 100 cm. Eksperimen ini sangat relevan untuk diimplentasikan pada proses pembelajaran hortikultura, mengingat eksperimen ini mampu mengembangkan potensi dan kreativitas mahasiswa serta lamanya eksperimen relatif memadai yaitu 120 hari atau 17 minggu.
The increasingly rapid development of science and technology, as well as the influence of globalization has contributed to updates in educational so that one method taken by apply experiments in horticulture learning activities. This study aims to determine the effect of rice straw mulch on tomato production and the effectiveness of the implementation of this experiment in the horticultural learning process. This research experimental used144 of tomatoes plants that were divided into four groups. First group is the control group with the thickness of the straw 0%, second group with a thickness of mulch 5%, third group with mulch thickness 10% and fourth group with mulch thickness 15%. The results show there is a significant difference from the average weight of tomatoes after being given various mulch thickness treatments that was continued with the Least Significant Difference test with significant differences seen group 15% straw thickness where group had the highest tomato fruit weight with the average tomato fruit weight per plants 1426.72 g. This experiment is quite effective in implementing horticulture learning because this experiment takes only 116 days and can increase activity, motivation, creativity, foster students' rational and scientific thinking.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
