Abstract

The common form of palm sugar is usually in solid form and needs to be dissolved before use. To facilitate utilization, palm sugar is processed into liquid palm sugar. One of the issues encountered during the production of liquid palm sugar is the formation of foam, which can decrease the quality of the liquid palm sugar. Therefore, measures are needed to anticipate foam formation, including the addition of candlenut seeds and coconut oil. This study aims to determine the influence of the addition of candlenut seeds and coconut oil on the physical and chemical characteristics of liquid palm sugar, identify the optimal levels of candlenut seeds and coconut oil that meet the national standard (SNI) for liquid palm sugar, and produce a liquid palm sugar product preferred by consumers. The research employed a Randomized Complete Block Design (RCBD) with a single factor and six treatment levels of candlenut seeds and coconut oil (0%, 0.1%, 0.3%, 0.5%, 0.7%, and 0.9%). Data analysis was conducted using Analysis of Variance (ANOVA). Based on the research results, the addition of candlenut seeds and coconut oil significantly influenced the viscosity of liquid palm sugar but had no significant effect on its color and moisture content. The addition of candlenut seeds and coconut oil had a significant impact on the chemical quality of liquid palm sugar, affecting ash content and total insoluble solids but showing no significant effect on pH and total dissolved solids. The treatment with 0%, 0.1%, and 0.3% additions of candlenut seeds and coconut oil met the quality requirements for moisture content, while the ash content in the 0%, 0.1%, and 0.3% treatments also complied with the standards. The addition of 0.9% candlenut seeds and coconut oil resulted in liquid palm sugar that met both SNI standards and consumer preferences.

Abstract

This study aims to analyze the effect of oxygen absorber on the color stability of gelamai. It evaluates changes in chroma and hue angle using the CIE Lab color system under two types of packaging (PE and vacuum) and two storage temperatures (room temperature and freezer) during 8 days. The colour changes observed in the samples were caused by oxidation. Throughout storage, the oxygen absorber reduces or retardes oxidative reactions. These findings revealed that vacuum packaging slowed colour changes more effectively than PE packaging, especially at room temperature, while freezer storage produced more complex and nonlinear patterns, likely due to physicochemical interactions. Kinetic analysis disclosed a difference in reaction rate constants (k) between packaging and temperature conditions, vacuum packaging disclosed lower kinetic value and more stable color than other conditions. PE room temp (R² = 0.9311), Vacuum room temp (R² = 0.5776), PE freezer (R² = 0.5847), Vacuum freezer (R² = 0.7258). Statistically disclosed no significant difference in all treatments. This study concludes that oxygen absorbers are effective in preserving the color quality of gelamai during storage.

Abstract

Coffee pulp is typically discarded by local communities without further utilization. In Babakan Bogor, Kepahiang Regency, Bengkulu Province. The coffee pulp has not yet been used productively, primarily due to the community’s limited knowledge and skills regarding coffee by-product processing. The objective of this community service activity was to provide participants with knowledge about the nutritional value of coffee pulp and the processing stages required to produce cascara. The methods employed included (1) preparation through coordination between the community service team and the target audience, and (2) an educational extension approach for material delivery. The implementation of this program was carried out successfully, with a high level of enthusiasm from participants. The activity has contributed to improving the community’s knowledge of coffee by-product utilization, specifically in processing coffee pulp into cascara tea.
