Abstract

Surface roughness is an important parameter in turning processes, as it directly affects the performance and service life of mechanical components. This study aims to examine the influence of feed rate, spindle speed, and coolant application on the estimated surface roughness (Raest) of ST 37 steel under conventional turning conditions. A 2³ full factorial experimental design was employed, involving eight treatment combinations consisting of two feed rate levels (0.040 and 0.100 mm/rev), two spindle speed levels (315 and 400 rpm), and two cooling conditions (with and without coolant). Surface roughness estimation was carried out using digital image analysis with ImageJ software based on optical microscope images. The analysis utilized gray-level intensity distributions, which were then converted into roughness values using an empirical scaling approach. The results indicate that increasing the feed rate led to a rise in Raest ranging from 1.74% to 7.11%, while higher spindle speeds contributed to an increase in surface roughness between 4.54% and 11.91%. In contrast, the use of coolant reduced surface roughness by an average of 9.20%, mainly due to its role in minimizing heat and friction during machining. The optimal parameter combination was obtained at a spindle speed of 315 rpm and a feed rate of 0.040 mm/rev with coolant, producing an Raest value of 1.495 µm, which falls within ISO roughness class N7. Overall, all specimens were classified within ISO N7, indicating a semi-finishing surface quality.

Abstract

This study aims to analyze the effects of Android-based learning and learning motivation on the Informatics learning outcomes of tenth-grade students at SMK Negeri 1 Sumatera Barat. Android-based learning is increasingly important in vocational education because it supports the development of digital competencies and independent learning skills required in the digital era. Previous studies have generally examined Android-based learning and learning motivation separately, while evidence regarding their interaction remains limited. This study employed a quasi-experimental method with a 2 × 3 factorial design involving 84 students in experimental and control classes. Data were collected using a learning motivation questionnaire and a learning outcomes test and analyzed through descriptive statistics and Two-Way ANOVA. The results showed that the experimental class achieved a higher mean posttest score (78.61) than the control class (68.33). The N-Gain score was also higher in the experimental class (0.55) than in the control class (0.34). Two-Way ANOVA revealed significant effects of the learning model (F = 32.47, p < 0.05), learning motivation (F = 22.86, p < 0.05), and their interaction (F = 6.43, p < 0.05) on learning outcomes. These findings indicate that Android-based learning is more effective when supported by high student motivation. This study provides empirical evidence for integrating technology-enhanced learning and motivational factors in vocational Informatics education.

Abstract

Laser cutting technology is widely used in the manufacturing industry because it is able to produce precise and efficient cutting. However, improper setting of cutting parameters can cause the formation of dross defects that reduce the quality of the cut. This research aims to analyze the formation of dross defects and determine the optimal cutting parameters on stainless steel materials with a thickness of 1 mm and a cutting length of 50 mm. The full factorial experimental design is used with three process parameters, namely cutting speed (S), focus point (F), and gas pressure (P). The height of the cutting results is measured and analyzed using the Analysis of Variance (ANOVA) method to evaluate the effect of each parameter on the observed response. The analysis results show that the focus point factor (F) has a significant effect on the dross height with a p-value of 0.029 (<0.05), while cutting speed, gas pressure, and all interactions between factors do not show a statistically significant effect. Contribution analysis shows that the F×P interaction gives the greatest contribution to the dross height variation of 29%, followed by the F factor of 27%. Based on the research results, the combination of optimal parameters to minimize the height of the dross was obtained at the focus point -2 mm, cutting speed 30 m/min, and gas pressure 10 bar. This finding shows that focus point setting is the main factor in controlling dross defects in the laser cutting process of stainless steel materials.
