Design and Study of Spinner Machine Peformance through Simulation and Proximate Analysis of Sepakung Village-Speciality Pegagan Leaf (Centella asiatica) Chips

Sepakung Village is a tourism village in the rural area of Semarang Regency which provides various farm products such as rice, coffee, brown sugar, vegetables and processed product, Sepakung Village-specialty pegagan leaf (Centella asiatica) chips. In the production chain of pegagan leaf chips, one of the influencing factors towards the storability or shelf-life is the cooking oil content within the packaged product, in which the excess cooking oil content should be minimalized. A design of 3-kg capacity onefold spinner machine is introduced as 2D and 3D model and simulated using Solidworks software to determine the individual parts’ strength and recommended material through creative and weighted objective method. After utilization of the spinner, the cooking oil and final nutrient contents are analyzed before and after the process by the duration of spinning time from 0 to 60 minutes. The cooking oil drained or removed from the chips were analyzed descriptively, while the data is analyzed using ANOVA to determine the effective spinning time. The result shows that the spinning duration had an effect toward the removed cooking oil content in which the graphical approach shows an exponential curve between the spinning duration and cooking oil content. The effective spinning duration is achieved at 30 minutes in which the product cooking oil content is at its lowest and highest difference compared to the previous results.
