Abstract

Gayo coffee is a well-known name for arabica coffee planted in Gayo Highland (GH). In GH, coffee production has a significant role in life prosperity. Previous reports mentioned the wholesaler mainly influences coffee trades, and most farmers tend to have minor shares among the other supply chain actors. But the information related to the value of the shares within the chain is not well reported. This study aims to identify the shares of added value within the supply chain actors of Gayo coffee for the produced output based on the Hayami method. This research was conducted in Kebayakan and Bebesen. Two sub-districts in the GH area. These two sub-districts were selected for sampling because they have representation for all supply chain actors and others requirements. Data were collected by in-depth interviews based on a designed questionnaire towards the identified supply chain actors: independent/cooperative farmers, middlemen, cooperative, processing farmers, and wholesalers. The obtained results identified five supply networks available in GH that started from red cherries to the green bean. As first-tier suppliers, cooperative farmers who sold their products in green beans to cooperatives have added values up to 22,41% higher than independent farmers who rarely sold their green beans to the wholesaler. Independent farmers tend to sell their harvest directly to middlemen, as they only share added value of up to 6,25 % for selling red cherries and 10% for wet parchment coffee. Moreover, middlemen, cooperatives, processing farmers, and wholesalers act as a second-tier suppliers. Amongst those actors, processing farmers have the highest added value (43,53%) than others since they produce specialty coffee as a premium product. Cooperative and wholesalers received similar input from farmers, but wholesalers received slightly higher added value (22,53%) than cooperative (22,67%). Meanwhile, middlemen received higher added value by buying red cherries than wet parchment coffee from farmers.

Abstract

Coffee is one of the largest commodities in the world. With coffee production more industrialized, waste generated a huge environmental problem. Coffee pulp is the main by-product of coffee processing. One of the components of coffee pulp is pectin. Pectin production from coffee pulp and its characteristics should be studied since extraction conditions used in production vary depending on raw material, desired type of pectin, and process economics. This research aimed to study the characteristics of pectin from coffee pulp extracted using oxalic acid under different times (80 and 90 minutes) and temperatures (100oC and 120oC). The parameters analyzed were yield, equivalent weight, water content, ash content, methoxyl, galacturonic acid, and degree of esterification. The result showed that extraction time and temperature affect the characteristics of pectin. The highest yield was obtained by extraction at 90oC for 90 minutes. The coffee pectin has colored light brown and is categorized as low methoxyl pectin. Overall pectin coffee pulp produced in this study has met the quality requirements of dried pectin by the International Pectin Producer Association (IPPA) standard
