Abstract

The design and material selection used during the manufacturing process significantly impact the environment due to their energy consumption and waste production, including carbon dioxide emissions. This study used the LCA tool eco-indicator to evaluate the environmental impact of producing clothes-hanging machines. Two different press tool designs were analyzed, each using other materials for punch and die. The results indicate that the press tool design 2 with SKD11 punch and die is suitable for long-term use but emits the highest CO2 emissions at 102.33 kg CO2. In contrast, the press tool design 1 with S45C punch and die is suitable for short-term use but emits the lowest CO2 emissions at 69.72 kg CO2.

Abstract

Corrosion in excavator tooth buckets is a major issue in the heavy equipment industry, especially in mining and construction. Exposure to water, humidity, and chemicals accelerates corrosion, reducing strength and wear resistance, which shortens component life and lowers operational efficiency. This study analyzes surface structure and material composition changes due to corrosion, aiming to enhance material durability through better selection and design. Using Scanning Electron Microscopy (SEM) and Energy Dispersive X-Ray Spectroscopy (EDX), corrosion effects on S45C steel were examined at up to 5000x magnification. The results show increased oxygen (O) from 3.56 WT% to 25.53 WT% and decreased iron (Fe) from 84.21 WT% to 59.35 WT%, indicating severe oxidation. Identified corrosion types include uniform and gap corrosion, highlighting the need for corrosion-resistant materials and protective coatings to improve excavator reliability

Abstract

Penelitian ini dilakukan bertujuan untuk mengetahui pengaruh parameter pemesinan dan variasi material terhadap konsumsi energi pada proses drilling. Metode penelitian yang digunakan adalah metode kuantitatif dengan menggunakan eksperimen. Pada penelitian ini memvariasikan kecepatan pemakanan dengan nilai 18, 37, dan 55 mm/menit dan variasi jenis material yang digunakan adalah Aluminium 6061, ST 37, dan ST 40 terhadap konsumsi energi. Proses penelitian dilakukan dengan menghitung konsumsi energi dan energi spesifik berdasarkan material removal rate (MRR). Hasil pada penelitian ini didapatkan bahwa pada Aluminium 6061, terdapat peningkatan kecepatan pemakanan secara signifikan dengan menurunkan konsumsi energi total dari 4499,91 J menjadi 2028,52 J dan energi spesifik dari 13,77 J/mm³ menjadi 4,83 J/mm³. Tetapi, pada material ST 37 dan ST 40, konsumsi energi kembali meningkat pada kecepatan 55 mm/menit setelah menurun di 37 mm/menit. Energi spesifik untuk ketiga material menunjukkan tren penurunan seiring meningkatnya MRR, bahwa energi spesifik Aluminium 4,8–13,9 J/mm³ lebih tinggi dari rentang 0,4–1,1 J/mm³. Sedangkan pada material ST 37 dan ST 40 5,8–16,4 J/mm³ berada dalam rentang standar baja 2,7–9,3 J/mm³. Dari penelitian ini dapat diketahui bahwa pada kecepatan tinggi, meskipun terdapat penurunan energi spesifik, namum konsumsi energi justru meningkat. Ini terjadi karena peningkatan gaya pemotongan yang membutuhkan daya lebih besar. Sehingga pentingnya memilih kecepatan pemakanan yang tepat sesuai jenis material untuk dapat munurukan konsumsi energi dalam proses drilling.

Abstract

Gesekan pada sistem mekanis menyebabkan peningkatan suhu dan rugi energi yang berdampak pada penurunan efisiensi kinerja. Pemilihan pelumas dengan karakteristik yang tepat menjadi salah satu faktor penting untuk mengurangi permasalahan tersebut. Penelitian ini bertujuan menganalisis pengaruh variasi jenis pelumas sintetik dan putaran poros terhadap temperatur kerja dan energi yang hilang pada bantalan luncur. Metode eksperimen digunakan dengan tiga jenis pelumas, yaitu semi-sintetik, full-sintetik, dan sintetik ester, pada tiga tingkat putaran poros: 1500, 2000 dan 2500 rpm. Temperatur diukur menggunakan thermometer digital, sedangkan rugi energi dihitung menggunakan persamaan W = V x I x t. Hasil penelitian menunjukkan peningkatan putaran poros berbanding lurus dengan kenaikan suhu dan rugi energi. Pelumas semi-sintetik memiliki performa terendah dengan suhu 48,8°C dan rugi energi 453,15 kJ pada 2500 rpm akibat kestabilan termal rendah dan viskositas tinggi (15,8 cSt). Full-sintetik lebih stabil dengan suhu 47,0°C dan rugi energi 448,36 kJ. Sintetik ester paling efisien dengan suhu 45,3°C dan rugi energi 437,76 kJ karena viskositas lebih rendah (13,6 cSt) dan kestabilan termal tinggi. Pelumas ini direkomendasikan untuk aplikasi mekanis berkecepatan tinggi.

Abstract

The use of CNC milling machines to produce components, especially aluminum brackets used for automotive, is one of the advances in the industrial field. The use of CNC milling machines has the advantage of producing processes with speed accuracy, and better workpiece quality than conventional machines. This research investigates energy consumption in the CNC milling process by varying the toolpath motion strategies—Zigzag, Constant Overlap Spiral, Parallel Spiral, and Parallel Spiral Clean Corners—as well as feed rates of 700 mm/min, 800 mm/min, 900 mm/min, and 1000 mm/min. The goal is to find out the best parameters for using energy in the machining process. The material used in this research is Aluminum 6061. The shape tested is a bracket. The simulation was conducted to determine the machining process time using Mastercam software. The simulation results indicate that the Zigzag toolpath motion strategy at a feed rate of 1000 mm/min produces the lowest energy consumption (307.620 Kilojoules) whereas the Parallel Spiral Clean Corners toolpath at a feed rate of 700 mm/min produce the highest energy consumption (457.142 Kilojoules). The selection of appropriate machining parameters has a significant influence on the efficiency of processing time and production costs. By selecting the right toolpath motion strategy and feeding parameters, the manufacturing industry can increase productivity and reduce production costs more effectively.

Abstract

This study aims to analyze the electrical energy consumption of a bench-type drilling machine, RYU RDB 13, by varying machining parameters in the form of spindle speed and feed rate. Electrical energy is a critical aspect of production efficiency in the manufacturing industry, particularly in machining processes that require continuous power consumption throughout the cutting operation. The material used in this study is aluminum 6061, chosen for its lightweight, corrosion resistance, and wide application in the automotive and aerospace industries. The drilling process was carried out using three spindle speed variations: 620 rpm, 920 rpm, and 1280 rpm, along with three feed rate variations: 0.04 mm/rev, 0.08 mm/rev, and 0.1 mm/rev. Current and voltage were measured using a digital wattmeter in real-time, and energy consumption was calculated in wattseconds (Ws) using power calculation formulas. The results indicate that increasing the feed rate and spindle speed leads to higher instantaneous power consumption. However, total energy consumption tends to decrease at higher speed and feed combinations due to shorter machining times. The optimal parameter combination was found at a feed rate of 0.1 mm/rev and a spindle speed of 1280 rpm, which resulted in the lowest energy consumption of 387 Ws and the fastest drilling time. This demonstrates that selecting the right machining parameters not only improves energy efficiency but also maintains or enhances productivity. The observed power consumption pattern typically shows a sharp increase at the beginning of the drilling process, a stable phase during the main cutting stage, and a rapid decrease towards the end of the cut. These findings contribute to a better understanding of the relationship between machining parameters and energy efficiency, serving as a basis for developing sustainable production strategies in the manufacturing sector that prioritize energy savings and cost reduction.

Abstract

A community service initiative was undertaken at UD. Risky Barokah, an egg-laying poultry farm in Sumberingin Kidul, Ngunut District, Tulungagung Regency. Operating since 2010 on a 7,000 m² site with nearly 10,000 chickens, the farm has faced persistent challenges related to water contamination and high electricity costs. To mitigate these constraints, a solar-powered water filtration system and a 1.1 kWp photovoltaic installation were implemented. The intervention was directed toward improving poultry health and egg productivity through access to clean water, reducing dependence on the electrical grid, and strengthening staff capacity through technical training. Outcomes demonstrated estimated monthly electricity savings of Rp247,500–Rp330,000 and consistent water quality that enhanced flock health and output, while simultaneously lowering the farm's carbon footprint. The project highlights the applicability of renewable energy and appropriate technology in promoting sustainable and cost-effective poultry production.

Abstract

FCAW welding is an automated welding process that employs a wire roll electrode to melt metal, using flux or powder within the electrode's core for protection. A common issue with FCAW welding is the occurrence of angular distortion and alterations in the length and width dimensions, particularly in thin plate iron materials, due to residual stresses from the welding process. This research aims to assess the impact of static thermal tensioning, preheating, and their combination on angular distortion in SS400 steel corner joints during FCAW welding, considering heat input during welding. True experimental research methodology was employed, with variations in preheating temperatures of 200°C, 250°C, 300°C, static thermal tensioning at 150°C, 200°C, 250°C, transient thermal tensioning at 150°C, 200°C, 250°C, and a reference method with no treatment to determine the welding approach that minimizes angular distortion. The material used was 3mm thick SS400 steel. Data analysis was performed using Minitab 18 software and the One-Way Anova method. The research results indicate a significant influence of static thermal tensioning, preheating, and their combination on angular distortion. The optimal welding methods identified are preheating-static thermal tensioning at 89°55', preheating-transient thermal tensioning at 89°50', static thermal tensioning at 150°C at 89°45', transient thermal tensioning at 150°C at 89°40', and preheating at 200°C at 89°35'.
