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.

This research was conducted to analyze the influence of family friendly policies and technostress on job satisfaction. This research also aims to determine whether work family conflict and work family benefits mediate family friendly policies, technostress, and job satisfaction. Two factor theory as a framework in this research. The sampling technique method uses census sampling where the entire population is sampled, and the research subjects are employees at CV Rahmat Aulia. Sampling used a questionnaire from 122 respondents. Data analysis used inferential Partial Least Square (PLS), namely variance-based SEM, with SmartPLS software version 3.0. The research results show that family friendly policies and technostress have no effect on job satisfaction. Family friendly policies do not have a positive effect on job satisfaction, and technostress also does not have a negative effect on job satisfaction. The mediation results show that work family conflict and work family benefits mediate between family friendly policies and technostress on job satisfaction. Suggestions for further research are to expand the reach of research on similar companies in a particular area.

The use of aluminum is increasing in the industrial sector, which is accompanied by an increase in aluminum waste if it is not handled quickly and appropriately, which will have a negative impact on the environment. Recycling is an alternative to overcome this problem. Recycling piston waste into pistons, data was obtained that there are insoluble aluminum elements, namely Cu, Fe, Si. The aim of this research is to determine the effect of recycling aluminum into pistons by tensile and impact testing with the addition of Cu 0.5%-1.5% & Fe 1%-1.5% with various tensile test speeds of 5mm/minute, 10mm/minute, and 15mm/min. The research uses independent variables, namely the addition of Cu & Fe to aluminum waste and the dependent variable is tensile strength testing and specific impact strength. The results of this research can determine how much Fe and Cu content is added in order to reach the standard piston content, increasing the hardness of aluminum without reducing the hardness and ductility too much, which is known from the strength values of recycled aluminum pistons through specific tensile and impact tests with average stress values. The highest was in Cu 1% - 1.5% & Fe 1% - 1.5% alloy with a tensile testing speed of 11 mm/minute of 196.19 MP, while the lowest stress value was obtained from Copper (Cu) 1% - 1.5 % & Iron (Fe) 0.5%-1% with a tensile testing speed of 8 mm/minute of 120.72 N/m2. The largest impact energy for aluminum piston specimens was obtained at 0.294 J in 1% - 1.5% Copper (Cu) and 1% - 1.5% Iron (Fe) alloys.

This study discusses the cooling of water with a system of spraying it into the free air. The energy source to drive the pump uses energy from sunlight. This research is to solve a problem in an area where it is difficult to get water so that the water for the cooling process must be cooled so that it can be used for the next process. The second problem is that the electrical energy is very minimal, so you have to use other energy that can be used for the cooling process. The process of cooling the water spray system into the air was chosen to solve this problem. The tools used in this study were a 600 Wp solar cell, a 300 W water pump and a spray pipe. The research was conducted during the dry season in August. The research results show that the temperature of the water in the pool is not homogeneous the deeper the water in the pool the lower the temperature. The higher the pool water temperature, the longer the cooling time will be. The greater the pump discharge, the faster it will take to cool the pool water. Solar energy is able to supply energy to drive pumps with pool water temperatures up to 45 C. This cooling system can be used at night because it is equipped with batteries. The results of this research can be used and developed to create a larger system. This cooling system does not cause any impact on the environment because the energy source is from sunlight which is environmentally friendly.
