Abstract

The aim of this research is to determine the effect of using organic fertilizer from kepok banana peel waste (Musa parasidiaca) as liquid organic fertilizer on the growth of mustard greens (Brassica juncea L). This research used a Completely Randomized Design (RAL) with 3 treatments and 1 treatment. without fertilizer and 1 treatment using liquid organic fertilizer from kepok banana peel with a volume of 240 mL, and 1 treatment with a mixture of 120 mL of fertilizer and 120 mL of water, then repeated 5 times for a total of 15 experimental units with the parameters measured being plant height, number of leaves, leaf length, and leaf width. The results of the study showed that the use of banana peel liquid organic fertilizer doses at a dose of 240 mL of liquid fertilizer, 240 mL of a mixture of liquid fertilizer and water, and 240 mL of water without a mixture of liquid fertilizer were significantly different between the first measurement after 12 HST with the second measurement 19 HST.

Abstract

Kristina Novianti, 2025. Pengaruh Model Pembelajaran Problem Based Learning (PBL) Terhadap Keterampilan Berpikir Kritis Siswa Pada Materi Keanekaragaman Hayati Kelas VII SMP Muhammadiyah Waipare, dibawah bimbingan Yohanes Nong Bunga, S. Si., M. Pd dan Sukarman Hadi Jaya Putra, S. Pd., M. Pd ABSTRAK Pemahaman siswa terhadap materi biologi masih kurang, berdasarkan hasil hasil observasi yang dilakukan di SMP Muhammadiyah Waipare. Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran Problem Based Learning terhadap keterampilan berpikir kritis pada materi keanekaragaman hayati. Penelitian ini dilaksanakan di SMP Muhammadiyah Waipare. Metode yang digunakan yaitu pendekatan kuantitatif. Teknik pengambilan sampel dilakukan dengan teknik purposive sampling dengan populasi semua siswa kelas VII dan sampel yang digunakan dalam penelitian ini yaitu kelas VII A sebagai kelas kontrol dan kelas VII B sebagai kelas eksperimen. Instrumen yang digunkan berupa kuisioner penggunaan model pembelajaran PBL terhadap keterampilan berpikir kritis dan pretes - posttes belajar siswa. Pengolahan data menggunakan program SPSS 29. Hasil penelitian menunjukan bahwa terdapat pengaruh model Problem Based Learning terhadap keterampilan berpikir kritis siswa pada mata pelajaran keanekaragamn hayati kelas VII. Hal ini dapat dilihat dari hasil rata-rata post-test pada kelas kontrol sebesar 62,75 sedangkan post-test pada kelas eksperimen sebesar 78,5. Adanya perbedaan signifikan antara kedua kelompok, dimana kelas yang menggunakan PBL menunjukan peningkatan yang lebih tinggi dalam keterampilan berpikir kritis. Penelitian ini memberikan pemahaman lebih dalam tentang peran PBL dalam meningkatkan pembelajaran biologi.
