Abstract

This study aimed to determine the effect of fermentation duration on the quality of cucumber pickles (Cucumis sativus L.). Cucumber pickles are fermented products involving lactic acid bacteria (LAB) activity, which enhances sensory attributes and nutritional value. A descriptive method was employed using three fermentation durations: 3, 5, and 7 days. Observed parameters included pH changes, color variation, and organoleptic tests (appearance, aroma, taste, texture, and flavor balance). The results indicated that 5-day fermentation provided the best overall quality, particularly in aroma, taste, and flavor balance, while 3-day fermentation showed better appearance and texture. Conversely, 7-day fermentation significantly reduced organoleptic quality. The study concluded that fermentation time significantly affects pickle quality, with the optimal fermentation period occurring on the fifth day.

Abstract

This study aimed to evaluate the effect of solid organic fertilizer made from dry leaves, cow manure, EM4, and molasses on the growth of pakcoy (Brassica rapa L.). The experiment was conducted using a Completely Randomized Design (CRD) with four treatments: control (no fertilizer), and fertilizer applications at concentrations of 15%, 30%, and 35%, each replicated three times. Observed parameters included plant height, number of leaves, and fresh weight. Data were analyzed using ANOVA followed by the Least Significant Difference (LSD) test at a 5% significance level. The results showed that the application of solid organic fertilizer significantly affected the growth of pakcoy. The 30% concentration yielded the best results, with an average plant height of 18.3 cm, 10 leaves per plant, and a fresh weight of 22.5 grams. Statistical analysis confirmed significant differences among treatments (p < 0.05). These findings indicate that applying 30% solid organic fertilizer effectively enhances pakcoy growth and supports sustainable organic farming practices.
