A BREAD DOUGH MIXING MACHINE ENGINEERING IN AN EFFORT TO INCREASE PRODUCTION CAPACITY IN DAMPIT SUKOHARJO BREAD

Introduction

A bread dough mixing machine engineering in an effort to increase production capacity in dampit sukoharjo bread. Boost Roti Dampit's production in Sukoharjo. This engineered bread dough mixing machine increases capacity & ensures homogeneous dough quality, solving current limitations for small businesses.

Abstract

Bread and cakes are foods that are commonly consumed by Indonesian people, even though they are not staple foods. The community needs bread and cakes as a snack to the staple food and also as a dish at certain moments such as holidays and celebrations. The high public demand for this product is exploited by Roti Dampit to become a promising business opportunity for the production of bread and cakes. As a small business, Roti Dampit has limited resources to meet customer needs. The most urgent thing is the availability of dough processing machines. Current conditions in making dough use machines with small capacities so that they are unable to meet production targets. Apart from that, the available tools produce poor quality dough where the dough has not been mixed evenly (homogeneously) so there are still lumps. With this condition, the proposing team created a solution by making a dough making machine with a larger capacity. To produce an even dough, the machine is equipped with a stirrer with 2 stirrer models. Test results show that the machine is able to process dough twice as fast as the manual method. To make 6 kg of dough it takes 12 minutes

Review

The paper addresses a highly relevant issue for small and medium-sized enterprises (SMEs) in the food production sector, particularly in regions like Indonesia where demand for convenience foods like bread and cakes is growing. The objective to increase production capacity and improve dough quality for "Roti Dampit" through the development of a specialized mixing machine is commendable. This initiative directly tackles critical bottlenecks faced by many local businesses: limited resources, outdated equipment, and the subsequent inability to meet market demand efficiently. The focus on practical, localized solutions to enhance productivity and product consistency is a strong point, demonstrating a tangible impact on a specific business's operational challenges. The proposed solution, a larger capacity dough-making machine equipped with dual stirrers, shows promise in addressing the identified problems. The abstract highlights two key improvements: a reported doubling of processing speed compared to a "manual method" and the ability to produce a more homogeneous dough, eliminating lumps. Quantifying the speed improvement (6 kg in 12 minutes) provides a concrete metric. However, the abstract's description of the "engineering" aspects is rather limited. Details regarding the design principles, material selection, specific technical specifications of the stirrers, safety features, energy consumption, or cost-effectiveness are conspicuously absent. Furthermore, while improved dough quality is claimed, the abstract lacks quantitative metrics or qualitative analysis beyond the absence of lumps, making it difficult to fully assess the extent of this improvement. The "manual method" used for comparison also needs clearer definition to establish a robust baseline. To elevate this work from a project report to a robust journal article, several clarifications and elaborations are recommended. Future iterations of this paper should include a detailed methodology encompassing the engineering design process, prototyping, and specific testing protocols. It would be beneficial to provide a comparative analysis of the new machine against existing small-capacity machines, not just a generic "manual method," in terms of throughput, dough rheology, energy efficiency, and operational costs. Quantifiable measures for dough homogeneity (e.g., rheological properties, gluten development analysis) would significantly strengthen the claims of improved quality. Additionally, discussing the broader implications for other SMEs, the potential for scaling the technology, and a more thorough economic analysis of the machine's impact on Roti Dampit's profitability would enhance the paper's overall scientific and practical contribution.
