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.

Abstract

The quality of the Garlic seed bulbs needs to be improved by seed propagation through tissue culture techniques to get uniform and big cloves. Utilizing the suitable color spectrum of light is one way to stimulate plant morphogenesis. This study aimed to identify the influence of light color and obtain the best color in the morphogenesis of garlic callus explants. This research was carried out from June to September 2022 at the Tissue Culture Laboratory, Faculty of Agriculture, Universitas Andalas. This study used a completely randomized design with three treatment levels: red, blue, and white. The F test analyzed observational data at a 5% level, followed by Duncan's multiple Range Test (DNMRT) at a 5% level. The results showed light color influences embryogenic callus formation and shoot formation from garlic callus explants. Blue light is better than red and white light in inducing embryogenic callus, increasing the rate of explants forming shoots but giving no significant difference in the length of the shoot.

Abstract

Lettuce is a vegetable crop with a demand that continues to increase yearly. This situation is influenced by increasing public awareness of healthy lifestyles and urban farming practices. Diverse genetic sources are essential in plant breeding programs to form varieties with superior characteristics to increase productivity. One of the methods that can be done to improve genetic variation is by introduction. This research aims to study the morphological characteristics of three varieties of introduced lettuce. This research was conducted in the experimental field of the Faculty of Agriculture, Universitas Muhammadiyah Jakarta, from July to November 2022. The study compared three introduced lettuce varieties from Turkiye and three national commercial varieties. The morphological characteristics observed included qualitative (leaf shape, leaf vein shape, leaf tip shape, and leaf colour) and quantitative (crop height, number of leaves, leaf width, leaf length, harvest age, gross weight, and consumption weight). The results showed that only V4 had the same qualitative characteristics as its comparison variety (V1). The results also showed that in terms of quantitative characteristics, V4 and V5 had a higher resemblance to their comparator varieties (V1 and V2, respectively), while V6 had a further similarity to its comparator variety (V3). These introduced varieties have phenotypic variability that can be used as sources of plant genetics for plant breeding programs.

Abstract

Biochar with a high organic matter composition is considered to be an ameliorant for Ultisol. Providing biochar as an ameliorant needs to be studied because it will cause an increase in micronutrients, most of which are excessive in Ultisol. This study aims to determine the effect of several levels of biochar dosage from corn cob as a base material on changes in micronutrients in Ultisol soil. This research was conducted in a greenhouse and in the Laboratory of Agrostology, Feed Industry and Soil Science, State Islamic University of Sultan Syarif Kasim Riau. Experiments with several doses of biochar as treatment, e.g., 0%, 5%, 10%, and 15% of the composition of the growing media were arranged in a Completely Randomized Design (CRD) with six replications. The parameters observed were the micronutrient content of Boron (B), Copper (Cu), Zinc (Zn), Iron (Fe) and Aluminum (Al). The experimental results showed that giving corn cob biochar with doses of 0.5%, 10% and 15% did not significantly change the levels of B, Cu and Zn Ultisol. Biochar at a dose of 10% significantly increased the soil Zn content and decreased Al-dd Ultisol solubility.

Abstract

Sugar palm seed germination does indicate by the appearance of a tissue that extends like a sponge called apokol which is penetrating the hard seed coat and can occur in several positions in germinated sugar palm seeds. No research reports discuss the relationship between this apokol position and the phenology of sugar palm seed germination. This research aims to study the relationship between apokol position and the growth of sugar palm seedlings and their genetic diversity. The research applies Experiment in Completely Random Design with four treatments, each repeated five times. The four treatments are the apokol position, namely A: Apokol in right-center, B: Apokol in left-center, C: Apokol in left-bottom, and D: Apokol in right-bottom. The results showed that the fastest time for the coleoptile emergence was 40 days after transplanting in the right-center apokol position. Morphologically, there was no significant difference in the sugar palm seedling growth with each apokol position. On the other hand, we found that there were genetic diversities among them revealed by Simple Sequence Repeat (SSR) markers. The palm seeds with the right-center apokol position included the first cluster, and the second cluster consisted of left-center apokol, right- bottom apokol, and left-bottom apokol.

Abstract

Indonesia has 26,000 species of orchids that are very potential and profitable. Grammatophllum stapeliiflorum is an orchid species that is increasingly difficult to find in its natural habitat. The addition of foliar fertilizer containing macro and micro nutrients can increase plant growth. The purpose of this study was to determine the effect of foliar fertilizer type, concentration and the combination of the two factors on the growth of the orchid protocorm G. stapeliiflorum. This study used a factorial completely randomized design with two research factors, namely the type of foliar fertilizer with 2 treatment levels, B1 = Gandasil-D and B2 = Growmore. The second factor, fertilizer concentration with 4 treatment levels, namely A0 = control (without foliar fertilizer), A1 = 1 g/L, A2 = 2 g/L, and A3 = 3 g/L. This study consisted of 8 treatment combinations which were repeated 4 times, resulting in 32 experimental units. The parameters observed were the percentage of live explants, the percentage of browning, and the percentage of protocorms growth stages. Data were analyzed by Analysis of Variance (ANOVA) and continued with Duncan's Multiple Range Test (DMRT) at a 5% level. These results indicated that the application of foliar fertilizers with Gandasil-D and Growmore affects the percentage of live explants and protocorm growth phases and also increase the percentage browning until of 32,5%. Gandasil-D is better for protocorm growth from globular to torpedo. The control is better for forming shoot of 22,5% compared to the use of foliar fertilizer.
