Abstract

This article is a literature review of several studies oriented toward the treatment of natural fiber to improve the surface morphology and tensile strength of the fiber. The method used is to review several studies that describe the physical and mechanical properties of natural fiber with different treatments such as immersion of sago fiber in liquid smoke, coconut fiber in NaOH, palm fiber in seawater, and smoking of king pineapple fiber, and banana stem fiber with liquid smoke. The results of the review showed that the treatment was able to increase the tensile strength of sago fiber by 26.77%, coconut fiber by 81.25%, palm fiber by 67.40%, waru bark fiber by 59,97%, coconut fiber with limestone water 34,96 %, king pineapple fiber by 74.45%, and banana stem fiber by 43.78%. The effect of some of these treatments can also change the morphology of the fiber. So, it was concluded that treatment was needed to change the physical properties of the fiber in the form of morphology and mechanical properties in the form of better fiber tensile strength so that the fiber used as a composite reinforcement could improve the mechanical properties of the composite.

Abstract

This study aims to analyze the application of Artificial Intelligence (AI) and robotization systems on the machining quality of CNC machines at PT Evergrown Technology Batam. The research focuses on two primary indicators of machining quality: surface roughness and product cylindricity, which were experimentally measured in a controlled laboratory environment. Additionally, production process efficiency was examined through indicators such as production time, production costs, defect rates, and tool wear. Data were collected from 25 observation units selected through purposive sampling and analyzed using a quantitative approach with the assistance of SPSS version 2.3. The analytical methods employed include descriptive statistics, simple linear regression, one-way ANOVA, and comparative analysis to evaluate pre- and post-implementation conditions of AI and robotization systems. The results indicate that the implementation of AI and robotization has a significant impact on improving machining quality and production efficiency, as evidenced by a significance value of p < 0.05. These findings suggest that integrating AI and automation into production processes is a strategic move for advancing modern manufacturing industries.

Abstract

This study aims to evaluate the impact of implementing an artificial intelligence (AI)-based robotic system on the quality of CNC machining products at PT Evergrown Technology Batam. A quantitative method was employed using purposive sampling on 25 observation units. The quality parameters analyzed include surface roughness and product cylindricity. Data analysis techniques involved linear regression and ANOVA tests to determine the significance of relationships between variables. The findings indicate that the application of AI technology in robotic systems significantly reduces surface roughness (Y = 2.736 − 0.136X; p 0.001) and improves the cylindricity accuracy of the machined products (Y = 0.075 − 0.005X; p = 0.005). These results suggest that intelligent robotic systems make a substantial contribution to enhancing machining precision and overall product quality. Therefore, the implementation of such technology can serve as a strategic solution to improve quality outcomes in CNC-based manufacturing processes.
