Abstract

One of the key elements in making high-quality sponge cake batter is consistent and precise mixing, ensuring all ingredients are well-blended and producing the air bubbles necessary for softness. The aim of this machine redesign was to overcome the limitations of the previous design by using a multi-stage pulley. By redesigning the machine, it can be tailored to more specific operational needs, improve product quality, and minimize wasted time. To achieve this goal, the sponge cake mixer, which previously used a fixed-size pulley system, was updated to be more efficient in regulating rotation speed. Therefore, research was conducted by replacing the pulley size variations with a 5-inch diameter with 840 rpm, 6 inches with 700 rpm, and 7 inches with 600 rpm. During the testing process, the dough was mixed and the time required until the dough was ready was recorded.Based on the results of the trial using a multi-level pulley, it was found that the average time for mixing sponge cake batter with a 5-inch pulley produced an average time of 37 minutes, while a 6-inch pulley produced an average time of 46 minutes, and for a 7-inch pulley produced an average time of 55 minutes. A 5-inch diameter pulley is the appropriate size for use in a redesigned sponge cake batter mixer machine because it produces the fastest mixing time, which is an average of 37 minutes, with a rotation speed of 840 rpm. This pulley size is able to increase the efficiency of production time without reducing the quality of the dough mixing results

Abstract

Waste management issues have become a national concern with serious impacts on social, economic, health, and environmental aspects. The low level of awareness among communities and industrial actors in managing waste has contributed to environmental pollution. Along with the development of cities and regions, the volume of waste including used lubricating oil from vehicles and motorized machinery continues to increase. Not only in large cities, but small workshops in rural areas also generate used oil waste, resulting in its widespread distribution across Indonesia. This study employed a field experimental method. The approach was conducted by testing fuel mixture compositions in a stove fueled by used oil to observe the effect of fuel composition on the combustion process. The results indicate that variations in fuel composition significantly affect combustion quality. In the mixture of used oil and kerosene, a ratio of 40:60 produced the highest flame temperature of 378°C, the fastest cooking time of 4.05 minutes, and a blue flame indicating more optimal combustion. In contrast, the 60:40 mixture resulted in the lowest temperature of 318°C, the longest cooking time of 5.07 minutes, and a predominantly orange flame. For the mixture of used oil and biodiesel (biosolar), the 40:60 ratio also demonstrated the best performance, achieving the highest flame temperature of 380°C, the fastest cooking time of 3.52 minutes, and a stable blue flame.
