Abstract

The depletion of conventional energy sources has prompted the exploration of alternative energy materials, one of which is coffee grounds. Coffee grounds can be processed into briquettes, a solid fuel with high carbon content, high calorific value, and prolonged combustion duration, making them a viable alternative energy solution. This study aims to determine whether the type and proportion of binder significantly affect the briquette properties and to identify the most effective binder for briquette production. The research utilizes an experimental design with a Complete Randomized Block Design (CRBD) consisting of two factors, with two replications. The binders used in this study are starch and arpus, with binder concentrations of 12%, 16%, and 20%. The briquettes were evaluated based on several parameters, including moisture content, volatile matter content, ash content, fixed carbon content, calorific value, and burning rate. The results indicate that binder type (Factor A) significantly affects all tested parameters, and binder proportion (Factor B) also influences the same parameters. The best moisture content was observed in the A2B1 treatment, which used arpus as a binder with a 12% proportion, resulting in an average moisture content of 4.72%. The lowest ash content was found in the A2B3 treatment (arpus binder, 20% proportion), with an average ash content of 4.31%. The highest calorific value was recorded in the A2B1 treatment (arpus binder, 12% proportion), with an average calorific value of 6334.03 cal/g. The best burning rate was found in the A2B3 treatment (arpus binder, 20% proportion), with an average burning rate of 51.83 mg/s. These findings suggest that arpus is an effective binder for coffee ground briquettes, with optimal performance achieved at specific binder proportions depending on the desired properties.

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

The depletion of fossil fuel reserves necessitates the adoption of renewable alternative energy sources. Bio briquettes derived from agricultural waste biomass, such as Fimbristylis globulosa (mendong) and corn cobs, offer a promising sustainable fuel solution. This study aimed to analyse the effects of raw material composition ratio (mendong and corn cobs) and adhesive type on the characteristics of bio briquettes. The research employed a Complete Randomized Block Design (CRBD) with two factors: (1) Raw material ratio (70% corn cob:30% mendong, 50%:50%, 30%:70%) and (2) Adhesive type (20% concentration: tapioca flour, cornstarch, sago flour). Analyses were conducted on moisture content, ash content, combustion rate, compressive strength, and calorific value. Results indicated that the raw material composition ratio had no significant effect on any tested parameters (compressive strength, moisture content, ash content, combustion rate, or calorific value). In contrast, the variation in adhesive type had a significant effect on all parameters. Thus, this study proved that the type of adhesive is a significant factor affecting the quality of bio briquettes, while the ratio of raw materials in the tested range did not have a significant effect.

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.
