Abstract

The study aims to identify the characteristics of the ground coffee industry products, feasibility, and the added value of ground coffee in the Kebun Tebu District of West Lampung. The research method that the ground coffee industry will use in the Kebun Tebu sub-district uses qualitative descriptive analysis to identify the feasibility of the ground coffee business using the R/C and B/C ratio indicators, and the amount of added Value resulting from ground coffee processing is calculated using the Hayami method. The research results show that Coffee bean processing activities are financially feasible for the West Lampung Kebun Tebu industry to undertake and continue. They are also feasible for the community because they are economically profitable. Feasibility analysis based on the R/C and B/C ratio indicators shows that the ground coffee business with honey and natural processes has R/C > 1 and B/C > 0 or is worthy of business. The added value resulting from natural and processed ground coffee honey is classified as having a high value-added ratio because the Value added ratio is >40 percent, and processing ground coffee is a capital-intensive activity.

Abstract

Candlenut shells are only used as fuel, and some are thrown away, so their use has not been maximized. Because of their high carbon content, candlenut shells may be used to create adsorbents. This study looks at how different activator concentrations of KOH activators can be used to make adsorbents from candlenut shells. The study will investigate how various activator concentrations affect the ability of adsorbents based on candlenut shells to bind molecules. Furthermore, the investigation will examine the possible uses of these adsorbents in diverse sectors, including air purification and wastewater treatment. This research was carried out using the Completely Randomized Design (CRD) method, which consisted of 1 activator KOH concentration of 0.5 M, 1 M, 1.5 M, 2 M, and 2.5 M with 3 replications each. The finding demonstrated that adsorbent products activated with 0.5 M KOH yield the highest quality and satisfied SNI 06-3770-1995 requirements for an ash and water content of 10.21% and 0.98%, respectively. The adsorbent product has an iodine absorption capacity of approximately 639.39 mg/g, comparable to SNI 06-3770-1995. For iron metal, the adsorbent product exhibits an adsorption capacity and absorption efficiency of 0.14 mg/g and 98.30%, respectively. The Freundlich adsorption isotherm model is suitable for this investigation, with a Kf value of 0.14 mg/g and an R2 of 0.9999.
