“…The moisture content was calculated in two bases, namely, the moisture content dry basis (MC db ) and the moisture content wet basis (MC wb ) [23]. The drying rate was expressed as Equation 5 [17,24,25], where R is the drying rate (kg water/kg solid x h), dMC db is the changes of moisture dry basis (kg water/kg solid), and dt is the interval of drying time measurement (h).…”

The open sun drying method needs to be improved. This study aimed to evaluate the performance of the greenhouse effect hybrid (GHE-hybrid) type tray dryer using solar and biomass energy in drying cloves as a sustainable dryer for future. The dryer has 10 series of thin layers at gap of 10cm and each layer contains of 4 separated trays by 0.80m x 0.75m cross-section. We had run 2 experiments at capacity of 72 and 244kg, respectively. Results showed that increasing the drying capacity will prolong the drying time. The low solar irradiation will also increase the use of biomass energy and the input energy in the system was dominated by biomass energy at level of 75%. The drying temperature ranged from 37 to 46°C. The humidity was relatively high while the air velocity in drying chamber was lower than 0.68m/s and non-uniformly distributed. The moisture of cloves was reduced below 14% in both experiment after 3 and 6 days drying, respectively. The thermal efficiency was about 14 to 15% and the drying efficiency was 17%. The use of GHE-hybrid dryer is promising to be used by farmers sustainably. However, the dryer needs some improvement on air circulation system.

“…Typically, this drying consists of a propulsion system, fans, heating elements, and control mechanisms. There are several different types of mechanical drying, including (1) cabinet/rack type [13], (2) solar dryers with combined energy [14][15][16][17], (3) tunnel type dryers [18], and (4) freeze dryers, which involve the processes of freezing and [19,20].…”

The National Socioeconomic Survey (SUSENAS) conducted in Indonesia in September 2021 found that the average consumption of red chili per month was 0.15 kilograms (kg) per capita per month. The average consumption of fresh chili per month is 40.90 thousand tons, and the cumulative total reached 490.83 thousand tons in 2021. Uneven chili production across time and region makes prices fluctuate, which affects inflation by 0.01–0.07%. Another problem is the imbalance of supply and demand between time and region, which impacts farmers’ welfare. Setting planting time and location and improving distribution can solve these problems. The application of technology that can extend the life of fresh chilies for one month is a solution for chili distribution from farmers to areas with high demand. One-wave roasting and drying technology can extend chilies’ freshness for six months. By producing chilies that have a shelf life of more than three months, it is possible to store them in warehouses using the warehouse receipt system. The application of the warehouse receipt system to chili commodities is also an alternative to solving postharvest problems. The distribution and application of technology that can extend the life of chili can increase its economic value and make chili not a commodity that contributes to Indonesian inflation.
