Abstract

This study investigates the potential of potato starch-based edible coatings (Amylum solani) to extend the shelf life and preserve the quality of tomatoes (Solanum lycopersicum L.) during storage. The experiment contributed to evaluating the effect of the coating on critical quality parameters, including weight loss, firmness, color stability, moisture content, vitamin C retention, and sensory characteristics. Tomatoes with edible coatings exhibited a slower rate of weight loss compared to uncoated samples, which is attributed to the coating's ability to form a protective barrier that minimizes water evaporation and respiration rates. Coated tomatoes also retained firmness more effectively, delaying the softening process caused by metabolic and enzymatic activity. The study revealed that the edible coating reduced the rate of color degradation by slowing the loss of chlorophyll and the formation of lycopene, preserving the tomatoes' visual appeal. Moreover, the coating significantly delayed the decline in vitamin C content by inhibiting oxidation and maintaining structural integrity, which was further reflected in the higher sensory scores for coated tomatoes. Organoleptic tests indicated that panelists preferred coated tomatoes due to their glossy appearance, firmer texture, and sweeter taste, although these preferences gradually decreased over time. Analysis showed that the coating extended the shelf life of tomatoes to 13.64 days, compared to 9.76 days for uncoated samples. These results highlight the efficacy of potato starch-based edible coatings as an environmentally friendly and cost-effective solution for reducing postharvest losses, meeting consumer demand for fresh produce, and improving food security. This study provides valuable insights into the practical application of edible coatings for preserving climacteric fruits such as tomatoes, with implications for sustainable agricultural practices.

Abstract

Wine coffee is produced through an extended fermentation process, during which the intensity of its flavor and aroma increases. The coffee variety used in this study is excelsa, known for its naturally sour profile and strong aroma, characterized by a unique combination of sour, sweet, and astringent flavors. The objectives of this study were to determine the effects of fermentation duration and roasting level on the alcohol content of excelsa wine coffee and to determine its sensory attributes. The study employed a Randomized Complete Block Design with two factors: fermentation duration (factor X) and roasting level (factor Y). The parameters analyzed included moisture content, ash content, caffeine content, alcohol content, and organoleptic test, which includes preference for color, aroma, and taste of the excelsa wine coffee brew. From the results of this study, it was found that the water content, ash content, caffeine content, alcohol content, and sensory evaluation (color, aroma, and taste preference) of the excelsa wine coffee brew. The results showed that moisture, ash, and caffeine contents met the specified quality standards. The best sensory results were obtained from samples fermented for 30 days and roasted at a medium level, producing a well-balanced taste, neither overly sour nor predominantly bitter.

Abstract

Binahong leaves are still widely used only as medicine, not yet able to reach a wider user profile. Research was conducted on the effect of drying methods and the addition of binahong leaf extract on the characteristics of biscuits. The purpose of this study was to determine the effect of three drying method variations and the addition of binahong leaf extract on biscuit characteristics, as well as to identify the drying method and concentration of binahong leaf extract that provide the highest antioxidant activity. The research design used was a Randomized Block Design (RBD) with two factors, namely drying method variations with three levels: direct sunlight, oven drying at 60°C, and indirect sunlight; and the addition of binahong leaf extract with three levels: 1%, 5%, and 10% of flour weight. The analyses carried out included physical properties (total color difference) and chemical properties (moisture content, ash content, fat content, protein content, carbohydrate by difference, and antioxidant activity). The results showed that both drying method and binahong leaf extract addition significantly affected the characteristics of biscuits. The best treatment was obtained in A2B3 (oven drying method with 10% binahong leaf extract addition), which produced the highest antioxidant activity of 60.33%. Further research is recommended on thickening or powdering the extract to reduce moisture content as low as possible so that the biscuits can meet the SNI biscuit standard 2973:2022, with a maximum moisture content of 5%.

Abstract

Organic fertilizers play a crucial role in improving soil quality and supporting sustainable agriculture in tropical regions. This study evaluates the quality of cow manure based on the solid organic fertilizer standards set by the Indonesian Ministry of Agriculture. Laboratory analyses were conducted on key chemical parameters, including organic C, C/N ratio, moisture content, macronutrients (N, P₂O₅, K₂O), and pH, accompanied by weekly composting temperature observations. The results show that the manure had a high organic C content (34.91%) and an ideal C/N ratio (17.24), indicating mature and stable compost. Moisture content (17.84%) and pH (8.17) were within the acceptable standard range, confirming good storage stability and suitability for acidic tropical soils. Nitrogen content (2.03%) met the minimum requirement, while P₂O₅ (1.26%) and K₂O (0.23%) were at moderate levels typical of cattle manure. Temperature measurements during composting showed a normal decomposition pattern, increasing from 32°C in week 1 to about 33°C in weeks 2–3 before declining in week 4, supporting the maturity of the final product. Overall, the analyzed cow manure meets the quality standards for solid organic fertilizer and has strong potential as a soil amendment and supplementary nutrient source in tropical agricultural systems.

Abstract

Background of study: Oolong tea is commonly produced from Camellia sinensis leaves, while the use of assamica variety has been rarely investigated. Differences in varietal composition and oxidation duration may influence chemical and sensory characteristics of oolong tea, particularly antioxidant performance and polyphenol content.Aims and scope of paper: This study examined how tea variety and oxidation time affect moisture content, polyphenols, antioxidant activity, and sensory properties of oolong tea. The scope included physicochemical and organoleptic evaluation to determine processing conditions that optimize functional quality.Methods: A randomized block design with two factors was applied, namely variety (sinensis and assamica) and oxidation duration (15, 25, and 60 minutes), each with four replications. Measurements included moisture, polyphenols, antioxidant activity using DPPH, and sensory evaluation of color, aroma, and taste.Result: Variety significantly affected moisture, polyphenols, and antioxidant activity, while sensory differences were observed only in color. Oxidation time significantly influenced antioxidant activity but not moisture or polyphenols. The highest antioxidant activity occurred in assamica at 15 minutes, whereas longer oxidation reduced antioxidant levels.Conclusion: The assamica variety produced higher polyphenol and antioxidant values than sinensis. Shorter oxidation preserved antioxidant activity, indicating that combining appropriate variety selection with controlled oxidation may enhance the functional attributes of oolong tea.

Abstract

Background: Biodiesel production efficiency is strongly influenced by reaction method, temperature, and reactant feeding strategy. Semi-batch transesterification offers better molar ratio control and reduced methanol waste compared to conventional batch systems. Aims: This study analyzes the effect of feed addition frequency and reaction temperature on biodiesel efficiency and characteristics using Refined Bleached Deodorized Palm Oil (RBDPO) as raw material. Methods: A Complete Block Design with two factors was applied: feed addition frequency (4×, 5×, 6× per period) and reaction temperature (40°C, 50°C, 60°C) with two replications. Biodiesel was produced using semi-batch transesterification with sodium methylate catalyst. Parameters measured included yield, density, pH, water content, glyceride profile, and methyl ester content. Data were analyzed using Duncan’s Multiple Range Test (5%). Result: The best treatment was 5× feed addition, 50°C, producing the highest methyl ester content (67.18%), yield (92.98%), density (877 kg/m³), pH 6.78, and low water content (1,401 ppm). Most quality parameters approached SNI 7182:2015 biodiesel standards. Conclusion: Semi-batch operation improves conversion control but is not yet fully optimal due to reverse reactions. Further optimization of methanol ratio and reaction time is required to suppress monoglyceride and diglyceride reformation.

Abstract

Water scarcity limits soil productivity, but applying biochar can effectively enhance soil water retention in vulnerable areas. This study evaluated the effects of biochar types and application rates on the maximum moisture content of sandy soils in Gunungkidul, Indonesia. A completely randomized design was used to test rice husk and blotong biochar, alongside raw rice husk and a control, at varying application rates. Maximum soil moisture capacity was experimentally measured to determine treatment efficacy. Results indicated that biochar application significantly influenced soil moisture retention. Among the treatments, a lower application rate of rice husk biochar provided the most substantial improvement in water holding capacity compared to the control. Conversely, higher rates of biochar or the use of raw materials were less effective and, in some cases, reduced water retention. Conclusively, optimizing both the biochar feedstock and its application rate is critical; specific low-dose biochar applications can optimally enhance soil moisture retention, offering a practical strategy for sustainable agricultural management in semi-arid regions.
