Abstract

The lathe process is part of machining, namely The machining process was carried out on the outer surface of a cylindrical or flat workpiece using a lathe machine, followed by testing with three variations of spindle speed and feed rate to determine their effect on the surface roughness of the workpiece. Subsequently, tests were conducted using three different spindle speed and feed rate settings to evaluate their impact on the surface roughness of the resulting workpiece. In addition, from previous studies, the test results using variations of N (spindle rotation) with Rpm 255, Rpm 585, and Rpm 900, and Variation f (feed) 0.0803 mm / rev, 0.1229 mm / rev, 0.1700 mm / rev, whether the Ra value obtained decreased with increasing spindle rotation, and increasing feed rate will make the surface roughness of the workpiece rougher, the controlled variables in this study were AISI 1045 steel specimen material, spindle rotation speed, CO2 coolant. from the data obtained, the results of the Ra value that decreases are inversely proportional to the spindle rotation, in other words, the greater the spindle rotation, the smaller or smoother the Ra value produced. However, on the contrary, the faster the feed rate, the more directly proportional to the increasing roughness values ​​of Ra, in other words, the greater the feed rate, the greater or rougher the value and results of Ra.

Abstract

This study aims to analyze the effect of cutting parameter variations on surface roughness in the turning process of AISI 1045 steel using the Taguchi method. The cutting parameters varied include spindle speed (rpm), feed rate (mm/rev), and depth of cut (mm). Experiments were carried out using a conventional lathe with a carbide insert (DCMT 070204 – PM 4335) and an orthogonal array design L9(3³). The analysis was conducted using the signal-to-noise (S/N) ratio with the smaller is better criterion and analysis of variance (ANOVA) to evaluate the contribution of each factor to surface roughness. The results show that the feed rate had the most significant effect, contributing 65.69% (F-value = 9.80; P-value = 0.093), followed by spindle speed at 22.04% (F-value = 3.29; P-value = 0.233), and depth of cut at 5.57% (F-value = 0.83; P-value = 0.546). The optimal parameter combination that yielded the lowest surface roughness consisted of a spindle speed of 900 rpm, a feed rate of 0.0803 mm/rev, and a depth of cut of 0.2 mm. These findings confirm the effectiveness of the Taguchi method in identifying dominant parameters with a minimal number of experimental runs.

Abstract

Gran serra housing in Palembang is one of the aeras that has not yet received clean water supply from the local water utility (PDAM). To meet daily water needs, residents rely on dug well water containing iron (Fe) at a concentration of 1,15 mg/L. this study aims to analyze the effect of aeration time variation on the reduction of iron content using the aeration-filtration method. During the aeration process, hydraulic parameters such as flow rate, velocity, Reynolds number, head loss, and loss coefficient were calculated. Aeration was carried out for 45 and 75 minutes, followed bya a filtration process. The results showed that after 45 minutes of aeration-filtration, iron content decreased to 0,92 mg/L (a 3% reduction), and after 75 minutes, it decreased to 0,37 mg/L (a 68% reduction). The aeration process yielded a flow rate of 0,000328 m3/s, velocity of 2,549508284 m/s, Reynolds number of 40.550563, head loss of 2,04204 and loss coefficient of 6,15755. These findings demonstrate that 75 minutes of aeration followed by filtration is effective in reducing iron levels in well water.

Abstract

Livestock farmers need to provide sufficient grass to be cut into animal feed every day. Farmers in Pinrang and the surrounding area still use sickles to cut grass. Therefore, when the grass is dense, it requires additional time and labor. The purpose of this grass cutting machine for animal feed was to build a grass chopper and assess its production capacity and effectiveness. Test data was analyzed using a comparative approach, which reflects the productivity level of the equipment. The findings showed that the grass cutting process involves rotating cutting blades. The selected transmission system has a single transmission consisting of a pair of 2.5 mm diameter pulleys for the motor and a 2.5 mm diameter pulley for the drive component. Chopping 0.5 kg of elephant grass using three cutting blades at rotational speeds of 730 rpm, 1100 rpm, and 1850 rpm took 8 seconds, 9.2 seconds, and 10.6 seconds, respectively. The analysis showed that the optimal method for chopping grass is to use three cutting blades. From this data, it can be concluded that as the chopper's rotational speed increases, the resulting chopped capacity also increases.

Abstract

This study aims to examine the effect of spindle speed and feed rate on surface roughness in the edge milling process using ST 37 steel material. A smooth surface finish is one of the main indicators of machining quality, as it directly relates to wear resistance, friction, and the overall performance of mechanical components. The independent variables in this research are spindle speeds (360 rpm, 580 rpm, and 875 rpm) and feed rates (40 mm/min, 185 mm/min, and 285 mm/min), while the dependent variable is surface roughness (Ra). The machining process was carried out using an Optimum vertical milling machine with a 10 mm diameter HSS endmill cutter. Surface roughness measurements were performed using a Surface Roughness Tester, model SJ-310. The test results indicate that increasing spindle speed tends to reduce surface roughness, resulting in a smoother finish. In contrast, higher feed rates lead to increased surface roughness. The combination of the highest spindle speed (875 rpm) and the lowest feed rate (40 mm/min) produced the smoothest surface. These findings confirm that selecting the appropriate machining parameters significantly affects the final surface quality in the milling process.

Abstract

The need for clean water as a primary requirement for survival demands effective management in terms of the volume and standard of water that can be used. The clean water needs assessment plan was designed using a case study approach, taking into account population projections and estimated water consumption in Ogan Ilir Regency until 2034. Basic and additional data collection is one of the methods used, as is population estimation through the application of geometric and arithmetic methodologies. The arithmetic approach estimates the need for clean water at 45,035,981 m³/day (WHO), 19,815,831 m³/day (PUPR), and 21,617,271 m³/day (SNI) based on a projected population of 496,071 people in 2034; The geometric approach estimates the clean water requirement at 45,266,478 m³/day (WHO), 19,917,250 m³/day (PUPR), and 21,727,909 m³/day (SNI). By using EPANET 2.2 software, which can simulate the hydraulic system of clean The assessment of water distribution and the performance of the pipeline design is reinforced through a technical analysis of the distribution system

Abstract

Sexual violence against children continues to be a concern in Indonesia. In 2022, there were more than 14,500 cases of sexual violence against children (KemenPPPA). That number decreased to 6,198 cases in 2023, but sexual violence remains one of the most prevalent forms of violence. As of 2024, cases of sexual violence against children, including in Rejang Lebong Regency, Bengkulu, continue to occur. This study aims to determine the effect of sexual education on increasing knowledge of fifth and sixth-grade students at SDN 104 Rejang Lebong about sexual violence prevention. This study used a quasi-experimental design with a pretest-posttest one-group design. 38 students were selected as samples using stratified random sampling. Data were collected through questionnaires filled out before and after the intervention, which consisted of sexual education using animated video media. The results showed that before receiving sexual education, most students had a sufficient level of knowledge (52.6%). After the intervention, there was an increase, with 60.5% of students achieving a good level of knowledge. The Wilcoxon test results showed p-value of 0.000 (p<0.05), indicating a significant effect of sexual education on improving students' knowledge about sexual violence prevention. These findings indicate that sexual education through animated video media can be an effective method for improving students' understanding. Therefore, sexual education should be integrated into the school curriculum as a preventive measure to protect children from the risk of sexual violence.
