Abstract

Botrytis cinerea, a fungal pathogen, is largely to blame for the significant decline in cherry tomato prices. Chitosan, a natural biopolymer, has been explored as an alternative coating material to enhance fruit resistance and preserve postharvest quality. This study looks at how well chitosan edible coatings, applied by spraying and dipping, can prevent Botrytis cinerea infection on cherry tomatoes. The fruits were intentionally infected by making cuts and soaking them in a solution containing the pathogen, and then they were treated with chitosan coatings. The coated fruits were incubated at room temperature for 14 days and assessed periodically on days 1, 7, and 14 for weight loss, disease incidence, and sugar content (°Brix). Results showed that the dip coating method significantly reduced weight loss and disease incidence compared to other treatments, with the lowest weight loss recorded at 0.87 grams and disease incidence at 22.22%. The highest sugar content was observed in the uncoated control group (7.23° Brix), indicating that coatings might slightly affect sweetness. Both ways of using chitosan successfully prevented the growth of Botrytis cinerea and kept the quality of cherry tomatoes satisfactory while they were stored. These findings suggest that chitosan edible coatings, especially when applied by dipping, offer a promising, environmentally friendly postharvest treatment to reduce decay and prolong the shelf life of cherry tomatoes.

Abstract

Lembang Tadongkon is a highland area with considerable potential for horticultural development. Its fertile soils, deeply rooted farming traditions, and the availability of local labor make it highly suitable for development as an agropolitan hub. This study aims to identify leading horticultural commodities in the region and formulate strategies for their sustainable development. The methods employed include Location Quotient (LQ) analysis, Shift Share analysis, and SWOT analysis. Data were obtained from both primary and secondary surveys and analyzed in two stages: qualitative SWOT (SWOT matrix) and quantitative SWOT (weighting and scoring). The results of the LQ, Shift Share, and Klassen typology analyses for eleven horticultural commodities in Lembang Tadongkon reveal that five commodities have LQ >1 spinach (1.21), cabe katokkon chili (1.07), long beans (1.24), water spinach (1.09), and eggplant (1.38) indicating that they are base commodities with strong development potential. However, only tomatoes exhibited positive growth in the Shift Share analysis (0.84), while the remaining commodities showed negative growth. According to the Klassen typology, all commodities remain in the “Lagging” category, as both their contribution and growth rates are below the regional average. Accordingly, strategies are required to enhance cultivation technology, post-harvest management, and institutional capacity to transform base commodities into sustainable leading commodities. Quantitative SWOT analysis positions Lembang Tadongkon in Quadrant I (progressive), indicating that the area possesses substantial strengths and opportunities for integrated development. Recommended strategies include production expansion, downstream product development, strengthening farmer organizations, and leveraging agro-tourism potential based on local flagship commodities.

Abstract

The addition of inorganic fertilizers to overcome the limitations of organic fertilizers in the form of compost pellets affects the microbial life within them. Meanwhile, the biological activity of fungi as biocontrol agents, biofertilizers, decomposers, and plant growth promoters is highly essential. This study aimed to determine the optimal NPK fertilizer dosage for compost pellets. The research was conducted from October to December 2024 at the PEMTA Laboratory, UIN Suska Riau. The research employed a qualitative descriptive method with six treatment levels. The results showed that the treatment without NPK addition produced 7 fungal isolates with a population of 5.0 × 106 cfu/g; addition of 1% NPK yielded 11 isolates with a population of 3.5 × 106 cfu/g; 2% NPK resulted in 10 isolates with 1.0 × 105 cfu/g; 3% NPK had 7 isolates with 6.0 × 105 cfu/g; 4% NPK showed 4 isolates with 5.0 × 105 cfu/g; and 5% NPK had 7 isolates with 1.2 × 105 cfu/g. Referring to the original source of the isolates, which were derived from compost shaped into pellets, the biological activities of the fungal isolates were predominantly decomposers, followed by phosphate-solubilizing fungi. The number of isolates acting as biocontrol agents and producers of plant growth regulators (PGRs) was relatively low.
