Abstract

Cherry tomatoes are prone to deteriorate during storage. Proper post-harvest technology is needed to maintain the quality of cherry tomatoes. This research aims to examine the effect of chitosan coating and storage temperature on the quality of cherry tomatoes and determine the optimal treatment. Cherry tomatoes of the Fortesta variety were used for experiment. Cherry tomatoes were dipped in chitosan solution with concentrations of 1% and 2%, and control. Each group of cherry tomatoes was then stored at temperatures of 15°C and 25°C. The research was arranged under a factorial completely randomized design with three replications. Measurement was performed on respiration rate, weight loss, firmness, total soluble solids, and organoleptic tests (freshness, color, and aroma) of cherry tomatoes. The results showed that chitosan coating affects the respiration rate, weight loss, firmness, total soluble solids, and organoleptic tests. Storage temperature affects respiration rate, weight loss, firmness, total soluble solids, and organoleptic tests. Chitosan coating of 2% concentration and storage temperature of 15°C were the best treatments that were able to suppress respiration rate, weight loss, firmness, total soluble solids, and were still accepted by panelists on the 21st day of storage. In contrast, the control only lasted until the 12th day of storage. Keywords: Cherry tomatoes, Chitosan, Cold storage, Edible coating, Quality.

Abstract

Garlic is widely recognized for its culinary, industrial, and medicinal applications, attributed to its sulfur compounds and allicin, which contribute to its pungent taste and distinctive aroma. This study, conducted in Sajen Village, Pacet District, Mojokerto, from January to May 2024, aimed to evaluate the effects of Phonska NPK and silica fertilizers on garlic production. A factorial experimental design with two factors was employed using a Split-Plot Design within a Randomized Complete Block Design (RCBD). The main plots were treated with silica fertilizer at concentrations of 0 g/L, 5 g/L, 10 g/L, and 15 g/L, while the subplots received Phonska NPK fertilizer at rates of 0 kg/ha (control), 400 kg/ha, 600 kg/ha, and 800 kg/ha. Data were analyzed using analysis of variance (ANOVA) and the HSD test at a 5% significance level. Results indicated that the combination of 0 g/L silica fertilizer and 800 kg/ha Phonska NPK fertilizer yielded the highest garlic production. Although the individual application of Phonska NPK fertilizer did not have a significant effect, the absence of silica fertilizer (0 g/L) significantly influenced leaf width and the development of generative structures. Keywords: Harvest, Nutrient, Potassium, Tuber size.
