Abstract

Various types of trees grow in Indonesia, one of which is the Nyatoh tree. Uses: This nyatoh wood tree is very useful as a material for building houses, making furniture, and so on. In the process of processing nyatoh trees into finished materials, shavings or powder will be produced, but the use of shavings or powder has not been utilized optimally. So the rest of the process makes the surrounding environment dirty and unsightly. This composite material has the advantages of adjustable strength, excellent fatigue strength, corrosion resistance, light weight and very low production costs. The aim of this research is to determine the tensile test value of nyatoh wood powder composites at volume fractions of 5%, 10%, 15% with a mesh size factor of 100, 150, 200 and a curing time of 2 hours with a heating temperature of 60 ?, 80 ?, 100 ?. The research method used is the full factorial method. The composite material is made using the hand-lay-up method. The highest tensile strength value in this research was a 5% sample with a mesh size of 200 and a curing time temperature of 60 ? with a tensile test result of 30.60 Mpa. Meanwhile, the lowest tensile strength result was 10.97 Mpa at a powder fraction of 5% with a mesh size of 100 and a curing time with a temperature of 60 ?. The size of the mesh greatly influences the tensile testing, where the higher the mesh used, the tensile strength increases. Meanwhile the heating process (curring time) also has an influence, but not so big, the higher the temperature of the curing time will cause a decrease in tensile strength.

Abstract

One source of natural fiber whose utilization still needs to be developed is fiber from corn husk which is cheap, abundant and environmentally friendly. The increasing production of corn plants causes an increase in corn husk waste which is also higher. Even though this corn husk has very strong fiber and can be used as a composite of natural fibers. Composites reinforced with natural fibers have excellent corrosion resistance properties, as well as lower production costs, are more abundant and are considered to be more environmentally friendly. The aim of the study was to determine the effect of soaking 7% NaOH for 1 hour, 2 hours and 3 hours and the effect of curing time at temperatures of 95°, 105° and 115° for 4 hours on the tensile strength of the corn husk fiber woven composite and to determine whether corn husk woven fiber composite can be applied as a car bumper manufacture. Making samples using the hand lay-up method. The analysis was performed using the factorial method. The highest results were found in the tensile test specimens using a variation of NaOH immersion time for 2 hours at a temperature of 95°C having a tensile test strength of 19.93 MPa. Meanwhile, the lowest tensile test strength value was 12.13 MPa using a variation of NaOH immersion time for 3 hours with a temperature of 115°C. Based on the standard for making car bumpers, the corn husk woven fiber composite can be applied as an alternative material for making car bumpers.

Abstract

Sanggar Pesona Wangka is a place for dance and music activities that have an important role in preserving Bangka Belitung culture. Sanggar Pesona Wangka also provides dance equipment rental. The process of renting dance equipment is still conducted conventionally so it takes longer. Another obstacle faced is the difficulty for tenants to obtain information regarding the availability of the dance equipment they need to rent. The conventional rent system is also considered inefficient because tenants must come to the studio to meet with the owner and directly select the dance equipment to be rented. This study aims to design and develop a website-based dance equipment rental system for Sanggar Pesona Wangka to facilitate the processing of the required data into accurate and easily accessible information for prospective tenants. The system implements a SAW (Simple Additive Weighting) method-based decision support system that can provide the best customer recommendations based on 2 criteria, namely the number of transactions and total transaction costs.

Abstract

Technology is currently experiencing rapid development, especially in the field of industrial engineering materials. One of the advances in industrial engineering materials is the use of ornamental plants as materials for making composites. Natural fiber reinforced composites are the right choice to be used as composite materials. The aim of the research is to obtain the highest tensile test values at fiber lengths of 60 mm, 80 mm, 100 mm and fiber volume fractions of 10%, 20%, 30% with 6% NaOH alkaline treatment for 1 hour and heating at 80? for 2 hours. The method used is full factorial. Samples were made using the hand lay-up method. The influence of fiber length and fiber volume fraction on tensile testing is very large. The longer the fiber used, the greater the tensile strength. Likewise with the percentage of fiber, the more it is, the stronger it is. The highest tensile strength was 39.03 Mpa at a fiber length of 100 mm and a volume fraction of 30%. Meanwhile, the lowest tensile strength result was 15.07 MPa at a fiber length of 60 mm and a fiber volume fraction of 10%. From the test results, the tongue-in-law composite can be used to make helmets, because its tensile strength value is higher than the tensile strength of SNI helmet material which is only 33.93 MPa.

Abstract

This research is a collaboration between STTKD Yogyakata and Frogs Indonesia, a startup that manufactures flying vehicles, with the aim of making the UAV Skywalker 1900 flying vehicle with Carbon Fiber reinforced composite materials to produce a structure that is stronger than the material commonly used, namely Styrofoam. The initial stage of making the UAV was to work on the Skywalker 1900 UAV design drawings and printed them with 3D printing using PLA Filament, the 3D printing results were then molded using Epoxy resin. From the resulting molding, the structure of the aircraft parts will be made with fiber glass reinforced composite materials using the Vacuum Bagging method. After the structure of the aircraft parts is completed, the electrical and avionic components are installed. The flight test results of the Skywalker 1900 UAV aircraft have a speed of around 15 m/s to 20 m/s, the weakness of this aircraft design is that it is still difficult to control, from the existing analysis this is caused by the aerofoil on the horizontal stabilizer causing lift in the tail of the aircraft of 1 newtons.

Abstract

The rate of transportation development in Indonesia faces a significant increase. However, the increase in transportation rates is not in line with the increase in residents, especially for people with disabilities. One form of discrimination against people with disabilities is the lack of accessible transportation equipment for wheelchair users. The lack of service facilities makes people with disabilities feel insecure. The lack of facilities provided makes people with disabilities choose to use individual vehicles to continue activities like normal people. The purpose of the research on providing transportation facilities for people with leg disabilities is very much needed in carrying out daily activities easily and without obstacles. The design of a wheelchair user disability vehicle uses the VDI 2222 design method with 4 stages, namely planning, conceptualizing, designing, and completing. From the conceptualization session, 3 design concept variations were generated which were then assessed based on technical and economical aspects. From the test results that were tested, the average speed that can be reached by this wheelchair user disability vehicle is 30 kilometers / hour.
