An edible coating is a thin layer composed of consumable materials applied to food surfaces. In post-harvest management, the application of edible coatings serves as an effective strategy to mitigate the deterioration of tomatoes and extend their shelf life. This study aimed to evaluate the optimal concentration of avocado seed extract for the formulation of an edible coating and to assess its application on tomato fruit. The research was conducted at the Agricultural Product Processing Laboratory, Polbangtan Gowa. The research was conducted using a Completely Randomized Design (CRD) consisting of four levels of treatment (avocado seed starch-based edible coating) with three replications. Each experimental unit comprised five tomato fruits, resulting in a total of 60 samples. The results demonstrated that avocado seed starch concentrations of 10 g/L and 15 g/L were effective as edible coatings for prolonging the storage life of tomatoes. Specifically, the 15 g/L concentration (P2) emerged as the superior treatment in maintaining weight loss stability, firmness, and color quality compared to other treatments.

This study aims to evaluate the impact of varied oven drying temperatures on the chemical quality, or proximate composition, of salted eggs, specifically focusing on the ash, fat, and carbohydrate content. Furthermore, the research identified the optimal treatment temperature to yield the best quality salted eggs. The research employed an experimental method utilizing a Completely Randomized Design (CRD) with four treatment groups: P0 (control, no oven drying), P1 (70°C for 6 hours), P2 (80°C for 6 hours), and P3 (90°C for 6 hours). Each treatment was replicated five times (n=5), using 10 duck eggs per replicate. The data obtained (percentage of ash, fat, and carbohydrate content) were analyzed using Analysis of Variance (ANOVA) followed by Duncan's Multiple Range Test (DMRT) when a significant treatment effect was observed. The results indicated that the oven drying temperature significantly affected (P < 0.05) the ash, fat, and carbohydrate content of the salted eggs. Oven drying at 90°C was proven to yield salted eggs with the best chemical composition, as evidenced by optimal ash, fat, and carbohydrate levels

Food product labels are strategic elements for the branding of Micro, Small, and Medium Enterprises (MSMEs) in Indonesia, serving as crucial instruments for market positioning in a competitive landscape. This study aims to analyze and synthesize the mechanisms through which food product labels enhance MSME branding. We employed a Systematic Literature Review (SLR) adhering to the PRISMA protocol. The research synthesized 10 scientific articles from the Semantic Scholar database, published between 2022 and 2024, within the specific context of Indonesian MSMEs. Through thematic analysis, this study identifies three primary mechanisms of labels as branding instruments: (1) Brand Legitimacy, where certification labels (Halal/P-IRT) act as trust signals; (2) Brand Identity, where visual design creates product differentiation; and (3) Brand Communication, which facilitates digital market positioning. The findings conclude that effective labeling requires a synergy between regulatory compliance (legality) and creative visual design to build strong brand equity. This study suggests that labels should be managed as intangible assets to improve MSME competitiveness in both local and digital markets

Cocoa bean shell (CBS) is an agro-industrial waste that has the potential to be used as a raw material for functional drinks due to its fiber and bioactive compound content. This study aims to determine the effect of the substitution level of cocoa bean shell powder on the characteristics of powdered drinks and to determine the best formulation based on sensory and chemical properties. The study used an experimental method with a Randomized Block Design (RBD) consisting of five substitution treatments of cocoa bean shell powder and cocoa powder (10:90, 15:85, 20:80, 25:75, and 30:70) with five replications, and Duncan's further test was carried out if there was a significant difference and to determine the best value. The parameters analyzed included organoleptic tests (color, aroma, taste, texture, and aftertaste) using a hedonic test as well as pH and Brix analysis. The results showed that the substitution of cocoa bean shell powder did not significantly affect the level of preference for color, taste, aftertaste, pH, and Brix. The 25:75 substitution treatment produced the best characteristics with an aroma value of 4.08 and texture 3.98. Thus, substitution of cocoa bean husk powder up to 25% has the potential to produce powdered beverages with sensory qualities acceptable to consumers.

Agarwood (Aquilaria malaccensis Lamk.) is a commodity with high economic value. The increasing demand for agarwood has promoted the development of agarwood cultivation, the success of which is largely determined by seed quality and the selection of appropriate seed source provenances. The selection of candidate plus trees is an effort to obtain high-quality seed sources. This study aimed to identify morphologically superior agarwood trees through plus tree selection at Agrowisata Kebun Gaharu Purwakarta site. The morphological paramVeters assessed included stem diameter, tree height, number of primary branches, crown height, crown area, and biomass. Data analysis was conducted using threshold values greater than the mean of each measured parameter. Candidate plus trees were defined as trees with parameter values exceeding the established thresholds. Correlation analysis was applied to examine relationships among parameters. The results identified 10 candidate plus agarwood trees selected from 81 evaluated trees, namely trees numbered 3, 8, 14, 15, 24, 29, 32, 34, 46, and 69. The highest parameter values were observed in candidate plus trees numbered 8, 32, and 34. Product-moment correlation analysis revealed significant and highly significant correlations between the number of primary branches and crown area, stem diameter and tree height, stem diameter and biomass, as well as tree height and crown height.

Abstract. Rapid urban development has led to the reduction of productive agricultural land, resulting in greater vulnerability of urban food security. The Integrated Urban Farming System (IUFS) is a sustainable agricultural approach that integrates crop production, aquaculture, and livestock subsystems within a circular resource-use framework. This study aimed to implement and analyze an IUFS model on a limited land area of 100 m² in Sukapura Village, Kiaracondong District, Bandung City. The research employed an applied research approach using descriptive-analytical and limited experimental methods over one production cycle. The IUFS model integrated hydroponic subsystem producing pakcoy, water spinach, and lettuce; Nile tilapia aquaculture; and local chicken farming. The results indicated that the hydroponic system achieved high and stable vegetable productivity, with the substitution between tilapia pond water and liquid organic fertilizer without reducing crop yield. The tilapia and chicken subsystems demonstrated good growth performance and improved feed efficiency through the utilization of vegetable residues. Overall, subsystem integration formed an effective nutrient cycle that enhanced input efficiency and reduced organic waste. The IUFS model developed in this study shows strong potential as a productive, efficient, and sustainable urban farming solution to support urban food security and household economic improvement.

The UHDP (Ultra High Density Planting) implementation system in Compreng District, Subang Regency has been introduced since 2018 as a trial by the Tropical Fruit Research Institute (BALITBU). Based on data from mango farmers in Compreng District, there are 8 villages with a total of 400 farmers, of which only 6 have implemented the UHDP system completely. The average productivity achieved is only 7444.5 kg/ha/year, which is still very far from the productivity that should be achieved if using the UHDP system. The purpose of this study was to analyze the relationship between farmer responses and the level of mango productivity in the UHDP system. The research method used was a survey. The population of 108 mango farmers in Mekarjaya Village was taken as a sample of 22 people, the category of farmers who have implemented the whole or only partially in the application of UHDP. The results of the study are as follows: (1). The assessment of the UHDP planting system preparation is in the medium category with a score of 456. UHDP cultivation care is in the medium category with a score of 660. UHDP harvest preparation is in the medium category with a score of 326; (2). The average productivity achieved is 7444.5 kg/ha/year with a score of 32, which is in the low category; (3). The correlation between farmer responses to the UHDP (Ultra High Density Planting) application system and the resulting mango productivity is 12%. The rs table value is 0.359 at α 5%. The calculated rs value < rs table, meaning there is no significant relationship between farmer responses and mango productivity in the UHDP system

FFree radicals are compounds that cause a decline in the function of cell tissue in the human body, resulting in degenerative diseases. Antioxidants, which are free radical-fighting compounds, are thought to be contained in bougainvillea flowers, including betacyanin compounds used as natural dyes. This study aims to identify the value of antioxidant activity and the levels of betacyanin compounds in flower leather extracts of bougainvillea flowers (fresh and dried). This study used a one-factor Randomized Block Design (RBD) method with different citric acid concentrations (0; 0.25; 0.50; 0.75%) and types of bougainvillea flower preparations, so there are 8 treatments with 3 repetitions. Data analysis was carried out using the analysis of variance (ANOVA) method. The analysis results showed the best antioxidant activity and betacyanin levels of 80.77 μg/mL and 9.18 mg/L in the fresh flower treatment with 0% citric acid concentration and 83.12 μg/mL and 14.93 mg/L in the dried flower treatment with 0% citric acid concentration. Its application in food products produces flower leather with thin, elastic sheets and good color.
