Abstract

Small and Medium Enterprises (SMEs) are the backbone of Indonesia's economy, contributing over 60% to the national GDP and employing more than 97% of the workforce. In Payakumbuh, culinary SMEs have significant potential due to the abundance of local raw materials and high demand for traditional foods such as rendang. Rendang Gadih is one such SME focusing on rendang production for both local and regional markets. However, inefficiencies in production, inconsistent quality, and manual management processes limit its competitiveness. This community service activity introduced the concept of Lean Manufacturing to improve efficiency and reduce waste. The main tools socialized were Value Stream Mapping (VSM), Process Activity Mapping (PAM), and identification of the eight types of waste, along with the application of Kaizen principles for continuous improvement. Implementation was carried out through preparation, socialization, and evaluation stages. The results of this activity are expected to help Randang Gadih enhance production efficiency, minimize waste, and strengthen competitiveness, serving as a model for other culinary SMEs in West Sumatra.

Abstract

This paper presents the design and implementation of an automatic oven for baking marble sponge cake using a PID-based temperature control system. The proposed system regulates oven temperature and air circulation to achieve stable and uniform baking conditions. Temperature control is implemented using a PID algorithm based on feedback from a K-type thermocouple sensor, while air circulation is controlled by a DC blower motor driven through PWM and a BTS7960 driver. The overall system is controlled by an Arduino Uno R3 microcontroller. PID parameters were determined using the Ziegler–Nichols reaction curve method, resulting in ???????? = 16.4, ???????? = 90 s, and ???????? = 22.5 s. Experimental results show that the oven was able to reach and maintain a setpoint temperature of 175 ∘C with acceptable stability during a 28-min baking process. Therefore, the developed system can be considered effective for automatic marble sponge cake baking requiring stable and controlled thermal conditions.
