This study examines the impact of workload and work stress on employee job satisfaction at PT Inhutani I UMI Gresik, a wood-processing company operating under Perum Perhutani. The research employed a quantitative design with an associative (causal) approach to identify the extent to which workload and stress contribute to variations in job satisfaction. Data were collected through questionnaires distributed to 48 employees selected using a simple random sampling method. The analytical process involved validity and reliability testing, classical assumption tests, multiple linear regression, as well as t-tests, F-tests, and the coefficient of determination (R²). The results indicate that workload and work stress, when considered simultaneously, have a significant influence on job satisfaction. However, partial testing revealed that workload did not exert a significant effect, while work stress had a statistically significant negative impact on satisfaction. Regression analysis further demonstrated that work stress emerged as the dominant predictor, accounting for a larger proportion of variance compared to workload, as reflected by the higher beta coefficient and partial determination value. These findings suggest that while workload may serve as a motivator when maintained within reasonable limits, unmanaged stress arising from role ambiguity, conflicting demands, and organizational pressures significantly undermines job satisfaction. The study underscores the importance of stress management strategies within organizations, particularly in high-demand industries such as forestry and wood processing. Practical implications include the need for supportive leadership, effective communication, realistic target-setting, and the implementation of employee assistance programs. By addressing stress more effectively, organizations can enhance employee well-being, foster greater job satisfaction, and ultimately improve overall organizational performance.

The main objective of this study is to analyze business innovation implemented by Coffee Shops in Coblong District, Bandung City, considering the increasing number of similar businesses emerging, triggering fierce competition in this industry. In facing these conditions, business actors are required to continue to innovate to be able to survive and excel in the competition. This study uses a descriptive analysis method with an approach to calculating the average value of each variable measured using a Likert scale. The study population consisted of 38 Coffee Shop entrepreneurs who served as research samples. Based on the analysis results, business innovation was measured through four main indicators, namely relative advantage, compatibility, dissemination, and communicability. In general, Coffee Shops in this area have succeeded in innovating well, although there are variations in achievement for each indicator. The indicator with the highest score is communicability, which refers to the ability of staff, especially baristas and cashiers, to interact with customers in a friendly, polite, and effective manner. This is not only limited to greeting but also creating a comfortable atmosphere so that customers feel appreciated, which ultimately increases customer loyalty. Conversely, the indicator with the lowest score is dissemination, which indicates that most customers tend to only order a specific type of coffee without exploring other menu variations. This condition can be seen as an opportunity to strengthen superior products, but also signals that the product diversification strategy is not running optimally. Therefore, it is important for coffee shop businesses in Coblong to develop a menu diversification strategy, both in terms of beverage types and service variations, so that the business remains competitive, relevant to diverse consumer preferences, and able to increase competitiveness amidst the increasingly rapid growth of the coffee shop industry.

Reverse engineering is the process of reproducing or recreating an existing model—whether it is a component, subassembly, or complete product—without relying on the original design documentation or CAD data. One of the key techniques that supports this process is photogrammetry, a method that utilizes a series of photographic images to identify, capture, and reconstruct the geometry of physical objects in three dimensions. Photogrammetry offers advantages such as low cost, portability, and non-contact data acquisition, making it a valuable tool in various engineering and industrial applications. This study aims to analyze the influence of two important factors—namely, the number of photographs taken and the intensity of lighting—on the dimensional accuracy or deviation of 3D models produced through photogrammetry-based reverse engineering. A quantitative experimental approach was used, where both variables were systematically varied to evaluate their effect on model precision. Data analysis was conducted using a Two-Way ANOVA factorial test to determine the statistical significance of each factor and their interaction. The experimental results revealed that using 54 photographs yielded the lowest average dimensional deviation among all tested conditions, although the difference was not statistically significant. Similarly, variations in light intensity showed no statistically significant effect on accuracy, but visually, an illumination level of 200–250 lux tended to provide more consistent and stable model outputs. No significant interaction was found between the two variables, indicating that they operate independently in affecting model accuracy. Overall, the combination of 54 photographs and a light intensity of 250 lux was visually identified as the most effective setup. The findings of this research contribute to the optimization of photogrammetry workflows in reverse engineering, offering practical insights for producing high-quality CAD models for use in design, prototyping, and manufacturing processes.

This study analyzes the effect of variations in cooling and extrusion speeds on a single screw extruder plastic machine to produce filaments. The method used is a factorial Design of Experiment (DOE) with a two-way ANOVA test, where the cooling speed (8.7 m/s, 11.8 m/s, 14.3 m/s) is varied using the inlet valve on the blower and extrusion (20, 30, 40 rpm) is varied using a tachometer. The testing process includes measuring the dimensions and weighing the filament after the extrusion process, and the data is processed using Excel and Minitab-21. The results show that increasing the cooling speed decreases the dimensions and density of the filament, while increasing the extrusion speed increases the dimensions and density of the filament. The interaction between the two is also proven to be statistically significant with 0.000 on dimensions and 0.014 on density ≤ 0.05 (p-value ≤ 0.05). The optimizer response determined the optimal combination at a cooling speed of 14.3 m/s and an extrusion speed of 20 rpm for a target dimension of 1.75 mm, while the optimal parameters for density were at a cooling speed of 8.7 m/s and an extrusion speed of 40 rpm, resulting in the highest density of 0.246 g. These recommendations are expected to improve the efficiency and quality of filament production.
