Abstract

In the Toboali region, Mang Dodi's terasi UMKM company still uses traditional methods, which leads to a drawn-out manufacturing process, uneven product quality, and small production levels.  Improved prawn paste printing techniques are therefore required in order to address the issue.  To solve this problem, a faster mould and cutter should be designed utilising the VDI 2222 research approach. A methodical design process that allows for detailed process tracing is what distinguishes this approach.  The two phases of the VDI 2222 method research process are concept formulation and planning.  In the context of the integrated carrier system, the screw and printing system, and the cutter inside a single system, the study's findings help to clarify the alternative selection idea.  This result reveals the ability to manufacture uniform goods, speed up processing times, and increase the quantity of products, all of which are commensurate with the research objectives.

Abstract

ABSTRACT The reason for conducting this review is to determine the effect of alkalization on the tensile strength and elasticity of composites of bamboo fiber and coconut fiber with a polyester matrix by varying the NaOH with concentrations of 0%, 2%, and 5%. Alkalization is one of the modifications of natural fibers to develop a compatible fiber-matrix. This exploration strategy uses the hand lay-up technique. In the main cycle, bamboo fiber and coconut fiber were treated without alkalization or 0% alkalization and in the next interaction, bamboo and coconut fiber were soaked in water (2% and 5% NaOH) for 2 hours. Then, at that time, each treatment process was formed into a composite according to the standard tensile test of ASTM D638 – II. The volume portion of bamboo fiber is 15%, coconut fiber is 15% and polyester resin is 70%, and the arrangement of bamboo fibers and coconut fibers is arranged horizontally. The matrix used in this study is a polyester resin matrix of type 157 BTQN with 1% MEKPO hardener. The highest concentration from this review showed that bamboo fiber and coconut fiber composites with NaOH variations of 0%, 2% and 5% respectively had tensile strengths of 34.9 MPa, 34.9 MPa and 54.74 MPa. The highest concentration with 5% NaOH produced the highest tensile strength of 54.74 MPa, while the coconut fiber composite without alkalization had the lowest tensile strength of 34.9 MPa.
