Lathifa Zahira. (2025). Pengaruh Pemberian Limbah Campuran Kulit Semangka (Citrullus vulgaris Schard.) dan Pepaya (Carica papaya L.) terhadap Pertumbuhan Tanaman Cabai Merah (Capsicum annum L.) [Skripsi. Universitas Syiah Kuala]. Dibawah bimbingan Wardiah, S.Pd., M.Bio dan Dr. Muhibbuddin, M.S.

Limbah campuran kulit semangka dan kulit pepaya mengandung senyawa organik yang dapat dimanfaatkan sebagai sumber hara bagi tanaman. Pengaruh pemberian limbah campuran kulit semangka dan pepaya terhadap pertumbuhan tanaman cabai merah belum diketahui. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian POC (pupuk organik cair) kulit semangka dan pepaya terhadap pertumbuhan cabai merah. Penelitian ini menggunakan metode eksperimental dengan pendekatan kuantitatif. Rancangan penelitian adalah RAL (Rancangan acak lengkap) non faktorial dengan tujuh perlakuan dan tiga ulangan. Konsentrasi yang digunakan dalam penelitian ini yaitu P0 (0% POC), P1 (10% POC), P2 (20% POC), P3 (30% POC), P4 (40% POC), P5 (50% POC), P6 (60% POC). Parameter yang diamati adalah tinggi batang (cm), jumlah daun (helai), jumlah bunga (kuntum), dan jumlah buah (buah). Data dianalisis menggunakan Analisis varian, sedangkan uji lanjut berdasarkan nilai KK yang diperoleh. Hasil penelitian menunjukkan bahwa pemberian POC campuran kulit semangka dan pepaya berpengaruh terhadap parameter penelitian, hal ini ditunjukkan dengan nilai F-hitung > F-tabel pada taraf signifikan 0,05. Kesimpulan dari penelitian ini adalah pemberian POC campuran kulit semangka dan pepaya berpengaruh terhadap pertumbuhan tanaman cabai merah dan perlakuan P4 (40%) ialah konsentrasi terbaik untuk meningkatkan pertumbuhan cabai merah.

Lathifa Zahira. (2025). The Effect of Mixed Waste of Watermelon Peel (Citrullus vulgaris Schard.) and Papaya (Carica papaya L.) on the Growth of Red Chili Plants (Capsicum annum L.) [Script, Universitas Syiah Kuala]. Under direction of Wardiah, S.Pd., M.Bio., and Dr. Muhibbuddin, M.S. Mixed waste of watermelon rind and papaya rind contains organic compounds that can be used as a source of nutrients for plants. The effect of providing mixed waste of watermelon rind and papaya on the growth of red chili plants is not yet known. This study aims to determine the effect of providing POC (liquid organic fertilizer) of watermelon rind and papaya on the growth of red chili. This study used an experimental method with a quantitative approach. The research design was a non-factorial RAL (Completely Randomized Design) with seven treatments and three replications. The concentrations used in this study were P0 (0% POC), P1 (10% POC), P2 (20% POC), P3 (30% POC), P4 (40% POC), P5 (50% POC), P6 (60% POC). The parameters observed were stem height (cm), number of leaves (strands), number of flowers (florets), and number of fruits (fruits). Data were analyzed using Analysis of Variance, while further tests were based on the KK value obtained. The results of the study showed that the administration of a mixture of watermelon and papaya peel POC had an effect on the research parameters, this was indicated by the F-count value > F-table at a significance level of 0.05. The conclusion of this study was that the administration of a mixture of watermelon and papaya peel POC had an effect on the growth of red chili plants and the P4 (40%) treatment was the best concentration to increase the growth of red chilies.
