Abstract

Alkali treatment of natural fibers has a role in removing hemicellulose and lignin layers. This layer prevents the matrix from bonding with the natural fiber cellulose structure. The use of an inappropriate type of alkali will reduce its effectiveness and can even damage the cellulose layer. This study compared the effectiveness of alkaline NaOH, CaOH and KOH in removing lignin and hemicellulose and their ability to maintain cellulose content. The use of the immersion method in alkaline solutions is well controlled. The FTIR characterization test was used to detect functional group changes, the TGV test to detect heat resistance ability, the XRD test to detect structural changes in crystalline and amorphous properties of sansevieria natural fibers. Furthermore, the tensile test to determine the effect of alkaline treatment on changes in mechanical strength Tensile strength. From the test results it was found that the alkaline NaOH gave the best characteristics by detecting the presence of cellulose, tensile strength and the nature of the crystalline atomic structure. Highlights: Effectiveness of Alkali Types: Comparison of NaOH, CaOH, and KOH effectiveness in removing lignin and hemicellulose while preserving cellulose content. Characterization Techniques: FTIR, TGA, and XRD tests used for functional group changes, heat resistance, and structural properties evaluation. NaOH Superiority: Alkaline NaOH treatment demonstrated best results in maintaining cellulose, enhancing tensile strength, and influencing atomic structure. Keywords: Alkali treatment, Natural fibers, Lignin removal, Cellulose preservation, Tensile strength.

Abstract

This study aims to explore the influence of workplace environment color on the performance of cracker factory workers. Focusing on a Small and Medium-sized Enterprise (SME) Krupuk, the research investigates the relationship between suitable workplace colors and worker performance. The psychological impact of workplace colors on mood and task execution is examined, considering factors like emotions, concentration, and alertness. Data analysis employs SPSS software for linear regression and cross-tabulation methods, revealing that an illumination level of 44 lux leads to a completion time of 14.15 seconds in the grinding section. The study highlights the desired impact of the color yellow and underscores the significance of color selection in enhancing worker performance. Highlight: Color-Mood-Performance Link: This research examines how workplace environment color influences cracker factory workers' performance, considering psychological aspects such as mood, emotions, concentration, and alertness. Data Analysis Methods: Employing SPSS software, the study employs linear regression and cross-tabulation methods to establish connections between suitable colors, worker performance, and an illumination level of 44 lux. Yellow's Desired Impact: Results highlight the desired impact of the color yellow on worker performance, emphasizing the importance of thoughtful color selection to enhance productivity. Keyword: Workplace Environment Color, Worker Performance, Psychological Impact, Illumination Level, Color Selection
