Abstract

This research aims to obtain optimal value for the surface roughness of the material AISI P20 on the Electrical Discharge Machining (EDM) Sinking process. In the present research, the Taguchi method is used to investigate the significant influence of process variables on the machining performance and determine the combination of process variables on the EDM process. Orthogonal array L18 (21 × 33) based on the Taguchi method is chosen for the design of experiment. The experiment is replicated twice to finding out the influence of four process variables such as type of electrode, voltage gap, on-time, and off-time on the response performance. Machining performance is evaluated by surface roughness as a response variable that had quality characteristics, smaller is better. These experimental data were analyzed using the Signal-to-noise ratio and Analysis of Variance. The analysis results show that the surface roughness is influenced by the type of electrode and on time. Combination of process variables to obtain optimal surface roughness are using graphite electrodes, and setting values of gap voltage 40 volt, on-time 250 μs, and off-time 20 μs. This combination of process variables can be applied to the manufacturing process using EDM sinking in order to produce a good quality product that determined based on the surface roughness value.

Abstract

Forklifts are loading and unloading vehicles that have recorded the highest number of near-miss incidents, primarily caused by human error and classified as unsafe behavior. In this context, driver behavior associated with the safety climate within the manufacturing company refers specifically to forklift operators. This study divides the safety climate into six variables: communication and procedures, job pressure, management commitment, relationships, safety regulations, and risk perception. The aim of this research is to analyze the relationship between safety climate and driver behavior among forklift operators in a manufacturing company. Data were collected using a questionnaire instrument with a total sample of 37 participants. The relationship was examined using the Pearson Product Moment Correlation test. The results show that communication and procedures have a moderate correlation with driver behavior (p-value = 0.544), while job pressure (p-value = 0.642), management commitment (p-value = 0.762), relationships (p-value = 0.712), and safety regulations (p-value = 0.607) show strong correlations. Risk perception also shows a moderate correlation (p-value = 0.544). These findings indicate that all six safety climate variables—communication and procedures, job pressure, management commitment, relationships, safety regulations, and risk perception—are significantly related to driver behavior.

Abstract

The high rate of occupational accidents in the food industry continues to be largely attributed to unsafe actions related to worker behavior. Within the context of food processing, which is inherently complex and high-risk, establishing a work environment that promotes psychosocial safety is crucial. Workers' perceptions of how well their organization prioritizes psychosocial safety may influence their compliance with and participation in workplace safety practices. This study aims to examine the influence of the psychosocial safety climate on safety behavior among assembling division workers in a soy sauce and syrup processing company. A quantitative research approach was employed using a survey method, with a validated and reliable questionnaire. A total of 70 permanent workers participated as respondents, and the data were analyzed using multiple linear regression with the aid of statistical software. The simultaneous test results indicated that psychosocial safety climate significantly affects safety behavior (p = 0.000). Partially, management support and commitment (p = 0.012), management priority (p = 0.000), and organizational communication (p = 0.001) had a significant positive influence on safety behavior. In contrast, organizational participation and involvement were found to be statistically insignificant (p = 0.628) and negatively associated. The coefficient of determination (R²) was 0.403, indicating that psychosocial safety climate explains 40.3% of the variance in safety behavior. These findings highlight the critical role of tangible management support, effective communication, and prioritization and involvement in fostering safe and sustainable workplace behavior.

Abstract

At the Sukodono molding company which produces Bioring cone cups using injection molding machines, a trial and error process to obtain parameter setting values on the machine is still applied in the early stages of production. This problem is detrimental to the company because they have to bear the production burden due to production delays. A solution is needed to optimize injection parameters with cycle time response. Therefore, this study proposes an analysis of the application of the Taguchi method by utilizing the signal for noise ratio to determine the influence of factors and also to optimize parameter such as temperature, pressure, and cooling time for the production process. The trial results show that the ideal blend of factors includes injection pressure parameters at level 1 with a value of 80 bar, injection temperature at level 2 in value of 225°C, and cooling time in level one with a value of 0.1 seconds.

Abstract

The preparation of standards and procedures for the production process in the manufacturing industry plays an important role in achieving acceptable products and in accordance with the desired quality. Based on the data from the quality control report of a foundry company, casting defects slightly exceed the maximum reject rate. It was found that the moisture content in the molding sand produced according to the procedure exceeded the maximum water content in the molding sand. The research was conducted as an effort to improve the quality of the company's production in reducing reject products. Permeability values of molding sand and quantitative area of cast defects will be compared, as a variations of bentonite and molasses binders , in three variations of the percentage addition of binder, respectively: 1, 3, and 5%. The Anova Two Way approach was used to statistically assess the results of the permeability test of the test specimens to ensure the effect of the predictor variables on the response. The results indicated that the more molasses, 5% added to the molding sand, gave the highest permeability of 53.50 ± 0.50 cm3/minute and gave the lowest cast defect area of 11.97%. The addition of bentonite binder produces a phenomenon that is inversely proportional to the addition of molasses binder.
