Abstract

Roses are known as a high-value commodity frequently used in various important events. However, they are susceptible to postharvest quality deterioration, which can affect their vase life and appearance. In this study, roses with a blooming stage of approximately 25–50% were immersed in melatonin and 6-benzylaminopurine (BAP) solutions at different concentrations. This research aims to analyze the effect of melatonin and BAP application on the freshness of cut roses. The parameters observed included flower vase life, flower wilting angle, increase in flower diameter, fresh weight, solution uptake, and chlorophyll content. The results showed that melatonin and BAP, applied individually or in combination, effectively extended the freshness of cut roses by up to eight days by maintaining solution uptake, flower quality, and chlorophyll content. This study provides new insights for farmers and researchers in improving the quality and longevity of cut roses through the use of plant hormones, particularly cytokinin.

Abstract

Basil (Ocimum basilicum L.) is widely used in traditional medicine due to its rich content of phenolic and flavonoid compounds. However, the natural production of these metabolites is limited. Callus culture offers a controlled method to enhance their accumulation, with medium composition, particularly precursor supplementation, playing a critical role. Phenylalanine, an aromatic amino acid, is a key precursor in the biosynthesis of phenolics and flavonoids via the shikimate pathway. This study aimed to evaluate the effect of phenylalanine on callus growth and the accumulation of total phenolic and flavonoid compounds in basil. The experiment was conducted at the Plant Tissue Culture Laboratory, Faculty of Agriculture, Universitas Padjadjaran, using Murashige and Skoog (MS) medium with phenylalanine concentrations of 0, 1.3, 1.6, and 2 g.L-1, each replicated six times. Results showed that phenylalanine treatments caused brown coloration, compact callus texture, and inhibited growth, as indicated by reduced fresh and dry weights. The 1.6 g.L-1 treatment produced the highest total phenolic content, while the 2 g.L-1 treatment yielded the highest flavonoid content. These findings suggest that phenylalanine can enhance secondary metabolite accumulation in basil callus, although it may suppress biomass growth.

Abstract

This study analyzes the influence of farmer group dynamics on the application of Good Agricultural Practices (GAP) in the cultivation of red chili in Sukajaya District, Bogor Regency. Red chili is an important commodity that maintains the stability of the national economy which is vulnerable to fluctuations in price and production. Data shows that there has been a decrease in the productivity of red chili in Sukajaya District despite an increase at the regency level, indicating that the application of GAP is not yet optimal. Using a descriptive quantitative approach and multiple linear regression analysis, this study involved 101 respondents from farmer group members. The results showed that the factors that significantly influenced the application of GAP were group task function, group objectives, guidance, group structure, effectiveness, and pressure, with a contribution of 72.2%. Characteristically, the majority of farmers are men (94%), of productive age 36-45 years (34.7%), with elementary school education (38.6%), very experienced in farming (40.6%), and have sufficiently productive land (41.6%). The strategy to increase the dynamics of farmer groups to optimize the implementation of Good Agricultural Practices (GAP) needs to pay attention to these factors, especially the function of group tasks that have the greatest influence, through training, technical guidance, counseling, and routine monitoring.

Abstract

Straw mushrooms are one of the nutritious edible mushrooms with high economic value. However, color changes during storage are one of the problems that impact the marketability. Post-harvest treatment in the form of the use of nano edible coatings, packaging, and storage temperatures can prevent gas exchange, control humidity and anti-browning agents in straw mushrooms. This study aims to evaluate the effect of nano edible coatings, packaging types, and different storage temperatures on the color stability of straw mushrooms. This study used a Completely Randomized Design consisting of a combination of nano edible coating treatments (nano sodium alginate and nano aloe vera), packaging types (vacuum, biodegradable, wrap packaging), and storage temperatures (room temperature (±25°C), 10°C, and 5°C), so that there are 18 treatment combinations. Each treatment was repeated twice so there were 36 experimental units. Each experimental unit consisted of two samples so that there were 72 samples at each observation time (1, 3, 5 days after storage), so that the total samples were 216. The results of the study showed that the combination treatment of nano sodium alginate with wrap packaging at a temperature of 10°C showed the best L*, a*, and hue values during 5 days of storage.
