Abstract

Modern manufacturing industries face challenges in improving efficiency and product quality. In this study, a pawn was designed using Autodesk Fusion 360, followed by a turning process simulation to optimize machining parameters such as cutting speed, feed rate, and depth of cut. The simulation was conducted to identify potential issues such as tool wear and dimensional inaccuracies before the actual production process. The results showed that implementing simulations effectively minimized production time, improved dimensional accuracy, and reduced tool wear. The applied optimization parameters successfully shortened the production cycle and produced defect-free products that met the required specifications. This study concludes that simulation and optimization in CNC turning machines not only enhance production efficiency and capacity but also ensure consistent product quality, making them highly relevant for modern manufacturing industries.Kata kunci: Simulation, Optimization, CNC Turning

Abstract

Liquid smoke is the result of pyrolysis of various types of biomass used in various industrial applications, including food preservation and waste treatment. This study aims to design and test a liquid smoke production device with a capacity of 120 ml per hour using six types of raw materials: coconut husk, coconut shell, straw, rice husk, corn cob, and corn stalk. The graph of the test results shows that the second experiment (test 2) produced a higher volume of liquid smoke than the first experiment (test 1), with the maximum volume reaching 310 ml. Nonetheless, the processing time varies depending on the type of raw material used. The results of this study show that optimizing the pyrolysis process can improve the efficiency of liquid smoke production, both in terms of volume and processing time. Thus, the device design used in this study has the potential to be further developed to increase production capacity and efficiency. Keywords: liquid smoke, pyrolysis, equipment design, production capacity, coconut shell.

Abstract

This study aims to analyze the strength of the 20-ton capacity welding test equipment frame using SolidWorks software-based simulation. The simulation evaluates the stress distribution, strain, and safety factor of the frame structure when receiving the maximum load. Analysis using the finite element method (FEA) is performed by modeling the frame along with boundary conditions and loads that match the actual test conditions. The simulation results show that the maximum stresses in the structure are still below the yield limit of the material, so the frame is considered safe to use. The highest stresses are distributed at the top of the frame especially around the load application area, while the bottom and legs of the frame experience lower stresses. The minimum factor of safety obtained in the simulation is 6.6 which indicates that the structure has high reliability against the applied load. Based on these results, the welding test equipment frame design can be said to be strong enough and safe to use for testing with a capacity of 20 tons. However, design optimization can still be done to improve the strength of the structure.

Abstract

The coconut frond cutter or coconut frond shredder is a device used to transform coconut fronds into small pieces, even turning them into a finely textured material. This study examines the design and development of a coconut-chopping machine that uses an 8 HP combustion motor. Structural analysis was performed on the machine frame by considering the maximum and minimum Von Mises Stresses. The analysis results show that the maximum Von Mises Stress in the frame is 1.670e+06 N/mm², while the minimum stress is 2.338e+04 N/mm². The displacement of the frame was observed at 2.642e-02 mm to 1.000e-30 mm. The safety factor of the frame was found to be 1.366e+02, indicating an adequate level of safety. Next, this study analyzed the shredding capacity of the machine. The analysis showed that the largest shredding capacity was 3619.30 kg/hour, which occurred at a high rotation of young fronds, producing fine shreds. Meanwhile, the smallest shredding capacity of 612.66 kg/hour occurs at low rotation of old fronds and produces coarse shreds. These results provide essential insights into using coconut shredding machines based on the rotation level and the processed material. This research contributes to the development of efficient and effective coconut processing technology.

Abstract

Noise pollution has become an increasingly concerning environmental issue, driving the development of sustainable acoustic materials as alternatives to conventional synthetic materials. This research conducts a systematic literature review on the acoustic effectiveness of natural fiber-based nanocellulose in sound isolation and absorption applications. The research method employs a qualitative approach with a comprehensive analysis of scientific publications from Scopus, Web of Science, ScienceDirect, and Google Scholar databases over the past ten years. The review results indicate that modification of natural fibers such as coconut coir, hemp fiber, banana pseudostem, and rice straw with nanocellulose at a concentration of 1-1.5% w/v is capable of improve sound absorption coefficients up to 0.7-0.9 in the 500-2000 Hz frequency range, comparable to synthetic materials such as fiberglass and mineral wool. This material demonstrates advantages in terms of dimensional stability improvement of 35-40%, lightweight density (150-300 kg/m³), balanced acoustic characteristics across a broad frequency spectrum, and biodegradable properties providing minimal environmental impact. The potential applications of this material are extensive in construction, automotive, and acoustic industries, with noise reduction capabilities of up to 8-12 dB. Despite facing challenges in raw material variability and production scalability, natural fiber and nanocellulose-based acoustic materials have promising prospects as sustainable solutions to global noise pollution problems with competitive performance against conventional materials.

Abstract

This study investigates the relationship between the use of Personal Protective Equipment (PPE) and the reduction of workplace injuries among workers at PT X. Using a quantitative research design with a pre-test and post-test survey approach, data were collected from 110 respondents selected through purposive sampling. The results demonstrated a significant decrease in workplace injuries after the implementation of PPE, with the average injury score dropping from 2.27 before PPE use to 1.50 after PPE use (p-value = 0.000). These findings indicate that the use of PPE is highly effective in reducing both the frequency and severity of workplace injuries. Factors such as worker discipline, awareness, and knowledge significantly influence the effectiveness of PPE use. The study concludes that consistent and proper use of PPE, supported by worker education and the availability of quality equipment, can substantially enhance workplace safety and reduce occupational health risks.

Abstract

Minyak bekas masak adalah limbah dari rumah yang sering dibuang sembarangan atau dipakai lagi dalam memasak. Penggunaan kembali minyak bekas dapat menimbulkan zat berbahaya seperti senyawa karsinogenik asam lemak trans dan radikal bebas yang dapat meningkatkan kemungkinan terjadinya penyakit degeneratif. Selain itu, membuangnya ke dalam saluran air dapat mencemari lingkungan serta membahayakan kesehatan masyarakat. Pemakaian minyak jelantah sampai dua kali pemanasan masih dapat ditoleransi. Namun jika lebih dari dua kali, terlebih jika warnanya sudah berubah menjadi kehitam-hitaman, maka minyak tersebut sudah tidak baik dan harus dihindarkan. Kegiatan pengabdian pada Masyarakat ini bertujuan untuk memberikan informasi kesehatan mengenai risiko minyak jelantah bagi kesehatan dan lingkungan, serta memberikan pelatihan untuk mengolahnya menjadi produk yang berguna, seperti sabun dan lilin aromaterapi. Metode yang digunakan dalam kegiatan ini mencakup penyuluhan kesehatan, demonstrasi, praktik langsung, dan penilaian peserta dengan memberikan kuisioner kepada peserta pengabdian kepada pengelola Bank Sampah Pasie Nan Tigo Kecamatan Koto Tangah Kota Padang. Hasil dari kegiatan menunjukkan adanya peningkatan pengetahuan peserta tentang bahaya kesehatan dari minyak bekas dan keterampilan mereka dalam membuat produk olahan yang aman dan memiliki nilai ekonomis, dimana peningkatan pengetahuan dan keterampilan mitra meningkat dari 48% ke 90%. Program ini menjadi contoh pendidikan kesehatan pencegahan yang berbasis pada pemberdayaan masyarakat dalam mengelola limbah rumah tangga.Kata kunci: minyak jelantah, edukasi kesehatan, sabun, lilin aromaterapi, pemberdayaan masyarakat
