Abstract: Confectionery products, particularly popular among individuals under 17, include treats such as jellies and gummies. Traditionally, the manual process of dropping gummy jelly into molds, one piece at a time, is labor-intensive and time-consuming. This method is susceptible to the gummy jelly's physical properties, which can coagulate when exposed to air below its melting point. This study presents the development of a semi-automatic gummy jelly dropping machine to streamline the handmade confectionery production process. The machine, fabricated from stainless steel with dimensions of 36.00 centimeters (width) x 56.00 centimeters (height) x 47.00 centimeters (length), utilizes an aluminum piston mechanism (34 millimeters diameter and 142 millimeters length) for controlled gummy jelly dispensing. A 950-watt heater warms the liquid gummy jelly in a basin located at the piston's back, with tests conducted at temperatures of 80, 100, and 120 degrees Celsius. Results indicate that the optimal temperature for the semi-automatic gummy jelly dropping machine is 120 degrees Celsius, achieving an average dispensing time of 99.35 seconds. The machine's production capacity is 36.66 kilograms per hour, with a maximum efficacy of 73.75 percent. The produced gummy jelly exhibits a moisture content of 12.07 percent, lightness (L) of 52.63±4.67.63, red/green (a*) of 0.27±0.11, and yellow/blue (b*) of 4.08±3.13. Its hardness measures 1027.75 grams, its gumminess is 916.25 grams, and its water activity (aw) is 0.80. The study is significant since it verifies that there is no microbial development.
