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

This study aims to develop Student Worksheets (LKPD) based on the Problem-Based Learning (PBL) model to enhance students' cognitive learning outcomes on the topic of Classification of Living Things at SMP Negeri 1 Mego. This development is expected to create effective and inclusive learning media, accommodating students' needs across diverse abilities and backgrounds, while supporting understanding of complex biological concepts.\n\nThe research was conducted using the Research and Development (R&D) model, which includes the stages of needs analysis, product design, expert validation, small- and large-scale trials, and product revision. The research subjects were seventh-grade students at SMP Negeri 1 Mego with varying levels of learning ability. Data were collected through observation, questionnaires, and interviews involving teachers and students.The results showed that the developed LKPD received excellent validation scores from experts. Validation by subject matter experts scored 96.88%, by language experts 100%, and by media experts 96.25%, all categorized as highly valid. The small-scale trial yielded feasibility levels of 89.68% according to students and 89.5% according to teachers, both categorized as highly feasible. In the large-scale trial, feasibility levels increased to 93.7% according to students and 100% according to teachers, also categorized as highly feasible.\n\nBased on these findings, the PBL-based LKPD is proven to be effective i
