Abstract

One form of processed red ginger to maintain its quality is dry powder. Therefore, a study is needed to determine the decrease in quality of red ginger powder in packaging during storage and to estimate its shelf-life. This research consisted of two stages, namely the first stage of making red ginger powder and the second stage of storing the ginger powder in packaging stored in an incubator using the accelerated shelf-life testing (ASLT) method. Quality analysis carried out were changes in moisture content, vitamin C, and color value. The results of drying and pulverizing red ginger produced red ginger powder with a water content of 10%, vitamin C content of 21.03 mg/100g and color value with a chroma value of 23.47. Based on the critical quality of red ginger powder, namely the chroma value, it can be concluded that the shelf-life of red ginger powder kraft paper packaging at 28 °C (room temperature) is 292 days and if it is stored at 30 °C then the shelf-life of red ginger powder in the same packaging material will be 212 days.

Abstract

Robusta coffee is the most widely cultivated coffee commodity in Indonesia. In the East Bolaang Mongondow Regency, the problem at the supplier level is limited market information, which makes the coffee beans' quality inconsistent, impacting the price and product quality image. This research aims to identify supply chain structure models and members, added value, and design a traceability system to support product quality validation. Robusta coffee supply chain participants and their interactions were identified at the Modayag coffee plantation in East Bolaang Mongondow. The data were collected through observations, interviews, and field studies. Supply chain analysis was performed using the Vorst method and the added value was calculated using the Hayami method. The traceability system design follows the system development lifecycle method. The findings indicate that the Robusta coffee supply chain in East Bolaang Mongondow Regency includes farmers, collector traders, processing plants, the retail industry, coffee roasteries, and consumers. Farmers profit from selling perfectly ripe wet coffee beans 42-43%, wet mixed coffee beans (8%), and dry mixed coffee beans 63-71%. A traceability system named Kinton was successfully developed and integrated with the Firebase database to store all information.
