Abstract
The government of Indonesia has a regulation called local content to push the manufacturing industries in order to increase their competitiveness. In order to reach that goal, technology transfer has been done, but it is a long way to go and impractical. So, one way to go is by the understanding of the product that has to be made. Reverse engineering is a specific technique to use because of its practicality. As the name implied, reverse engineering is the inverse of engineering design because the starting point is the product itself instead of the idea. In this paper, the product used as a case is the body of the fire-safe valve. The final goal of the reverse of the body part of the valve is the idea behind it or called the design intent. However, it is going to be a long process, and as the first step that will be presented in this paper, the goal is to get its CAD model of the fire-safe valve body.

Published: March 2020

AbstractThe walking balance of transtibial person has been widely documented in many literature. However, the effect of walking balance of transtibial amputee between body weight and a prosthetic foot is not widely known. This study was used for gait analysis to measure the walking equilibrium parameters amputated from 14 people with transtibial. To reduce variability among subjects at the time of testing, we carried out washing out for all subjects for 2 days. Data generated that all subjects walked in one direction straight to measure the walking balance and kinetic parameters. Design experiment with a crossover design, subjects with amputations walked for a distance of 80 meters, estimated time of 6 minutes and speeds about 1.20 to 0.15 m per sec, during the gait phase. The movement of the ankle in the plantar flexion position is reduced because in the final phase, the standing ankle becomes flexible. Correlation analysis shows that the effect of walking balance when wearing a prosthetic foot is measured during 1 gait cycle. The results depend on the design of prosthetic foot and how to walk.

Abstract
A person with physical disability is someone who cannot carry out an activity caused by a physical condition or a biological system. Data from SAKERNAS states that the rate of disability in 2017 reached 16.81% with a total disabled workforce of 11, 224, 673. BBRSPDF Prof. Dr. Soeharso Surakarta is the implementing unit for empowering persons with physical disabilities, where empowerment developed is sewing skills. The empowerment of sewing machines in the garment industry is generally designed to be able to be run for physically normal workers, this is different if a person has a transtibial disability. The operation of a sewing machine that previously used the sole of the sewing machine was changed to the use of the knee. This problem can be overcome by making special work facilities. The design of work facilities for persons with transitional disabilities needs to be adjusted between needs and abilities through a participatory approach. The design of the sewing machine pedal motor also contradicts technical problems, due to differences in the use of limb functions. This problem can be solved using the TRIZ method to obtain a design that fits the user’s needs.

Abstract
Utilization of new renewable energy has received special attention from the Indonesian government today because new renewable energy has several benefits from fossil energy, including environmentally friendly, non-polluting, abundant and will not run out throughout the ages. The growth of energy consumption is an average of 6.5 percent year, not yet balanced with sufficient energy supply, energy prices are increasingly expensive, energy subsidies are getting bigger, energy use is still wasteful. One way to overcome the problem of electricity is wind energy. Wind energy is a very abundant source of energy and there is no end of the year. At wind speeds of 1.5 to 3.0 m/sec, the voltage produced by wind power plants is linearly increased from 1.8 to 4.2 volts AC, from speed 3.0 to 4.0 m/sec, the voltage generated is in range from 5.0 to 6.5 volts AC. The DC voltage characteristic is equal to wind speed function. At wind speeds of 1.5 to 2.5 m/s, the voltage generated by wind power plants is linearly increased from 6.0 to 10 DC volts, from speeds of 2.5 to 4.0 m/sec the resulting voltage is stable 11 to 12 volts DC.
