<![CDATA[The production process of pempek at small and medium enterprises (SMEs) generally involves repetitive activities, particularly during the dough mixing and molding processes, which require considerable time and operator effort. This study aims to develop a semi-automatic pempek production system based on the Internet of Things (IoT) to assist the mixing, molding, and cutting processes at Pempek Ashifa MSME in Sematang Borang. The system uses an ESP32 as the main controller and integrates DC motors, an MG996R servo motor, manual push buttons, limit switches, and a Telegram Bot for remote control. System evaluation was conducted through functional testing, servo cutting testing, Telegram command response testing, and performance comparisons between conventional hand operation, manual machine control, and IoT-based control using 1 kg, 2 kg, and 3 kg of dough. The results showed that all manual control functions operated successfully, while the servo cutting mechanism successfully produced 50, 100, and 150 pieces from 1 kg, 2 kg, and 3 kg of dough, respectively, at a 90° servo angle and 3-second cutting time. The Telegram commands /aduk_on and /aduk_off achieved a response time of 3 seconds, while /cetak_on achieved 4 seconds. In the mixing process, the total processing time decreased from 47 minutes using the conventional hand method to 39 minutes using both manual-button and IoT control. In the molding process, the total time decreased from 180 minutes to 130 minutes. The production quantity remained consistent across all tested methods. These results indicate that the developed system can improve pempek production efficiency through reduced processing time and provide operational flexibility through local and remote IoT control. ]]>
