Abstract

PT. Marufuji Kenzai Indonesia one of furniture manufacture company in east java which use elbow stapler machine to assist production process. This elbow stapler machine is used to unite the elbow portion of the fiberboard (hardboard) material. However, the elbow stapler machine used is only able to be used to unite one side only. This of course inhibits the production process considering the number of stapler engines is not proportional to the number of fiber board material (hardboard) that is done. The method used to overcome the problem of delay in the work of fiberboard material (hardboard) is to make a two-sided flexible wooden elbow stapler machine using electropneumatic system. The working system of this machine will use three pneumatic cylinders where two cylinders are used for the stapler and one large cylinder is used to push the stapled material. Making this machine will be through several stages such as design, detail drawing, framework analysis, simulation, electropneumatic system design, to the assembly stage (assembly). Making the flexible wooden elbow stapler machine is expected to be able to overcome the problems that often occur in the process stapler material that has been produced. So that the work is usually done by one operator can be helped by the performance of this flexible wooden elbow stapler machine. So no more stacking of material in the stapler that resulted in disruption of some further process.

Abstract

Natural fiber composites are one of the innovative materials in an effort to solve the waste problem. Banana midrib and sawdust are plantation and forestry wastes whose utilization is very minimal. This research was conducted to make sandwich composites reinforced with banana midrib fiber and sawdust which is intended to be able to replace glasswool to reduce noise in the engine control room. The use of glasswool is not good for health which if the particles are inhaled it causes respiratory problems. The thickness of the core in the sandwich composite was varied by 2, 4, and 6 mm. Sound absorption testing is carried out according to the ASTM E1050-19 standard. The hand lay up method and polyester resin were used to make natural fiber sandwich composites. The highest sound absorption coefficient on specimens 2-35 is 0.77. All specimens of sandwich composites produced in this study met the requirements for sound absorption installations in buildings (? = 0.15). Along with the addition of the volume fraction reinforced on the core gives a parabolic effect with the addition of 35% giving the best results at thicknesses of 2 and 6 mm. The thinner the core provides a better sound absorption coefficient than other thicknesses.

Abstract

Pressure vessel production process often experiences problems, one of problems is changing data sheet from customer, in this case pressure vessel is already in the fabrication process. Changes data sheet are found in external pressure which is 3.5 kg/cm2g from previous 1 kg/cm2g, then recalculation must be carried out refers to ASME BPVC Section VIII Division 1. Then stress analysis is carried out with FEM through Ansys software simulation to determine loading conditions on pressure vessel design. Then fatigue life analysis was carried out to determine value of usage factor. Calculation of new external design pressure, was found that MAEP condition in shell is 0.158 MPa, this value is less than external design pressure of 0.34 MPa. Calculation results show that pressure vessel must be installed with a stiffener ring. Two stiffener rings are designed circumferentially on the outside of shell. Then results of stress analysis show that highest stress value is located on head. This value is still below maximum allowable stress value for material head, which is 138 MPa and results of fatigue life analysis show that usage factor value is less than one, thus pressure vessel there is no fatigue failure during thespecified age.

Abstract

Glass Fiber Reinforced Polymer (GFRP) is one type of material is widely used in manufacturing land transportation components, especially is train. The requirement of material for thetrain must be fire resistance. But in the other hand the GFRP material is still have weakness in high temperature. So, in this case it can provide an opportunity to take experiment about the GFRP material. The experimental method to improvement of GFRP material is adding additive fire retardant as a filler. The additive fire retardant used as a filler is magnesium hydroxide. The method for making specimens of GFRP fire retardant using hand layup method. GFRP which has been added with magnesium hydroxide is tested for fire resistance according to the ORE B 106.2 standart and the tensile strength according to the ASTM D-638 standart. The results show that after adding 30%, 35%, 40%, 45%, and 50% magnesium hydroxide by weight of polyester resin can increase the fire resistance of GFRP. The addition of magnesium hydroxide in the polyester resin caused reducing the tensile strength and modulus of elasticity. Fire resistance, tensile strength, elongation, and modulus of elasticity obtained optimum at the addition 35% magnesium hydroxide by weight of polyester resin. The result show that the carbonized surface of 68,67 cm2, time afterburn was 3,6 second after the flame has been extinguished, tensile strength of 70,86 MPa, elongation of 11,92%, and modulus of elasticity is 5,96 MPa. Therefore, GFRP with the addition 35% of magnesium hydroxide can be fire resistance, but it can't be used as an interior of the train because the tensile strength is less than standart.

Abstract

The high yield of coconut in Indonesia is positively related to the production of coconut shell waste which is difficult to decompose by microorganisme. Therefore, in recent years a method of utilizing coconut shell waste for charcoal and liquid smoke has been developed. So far, the process of making liquid smoke from coconut fiber (coconut coir liquid smoke) is usually carried out for 3-5 days and the amount of liquid smoke is very small. The use of liquid smoke is also adapted to clarify the qualities of liquid smoke, is used as a wood preservative and thickener, as an antimicrobial agent, and as a natural food preservative. In addition, e-liquid can also be used as a natural preservative for food, meat, and fish, it is also very suitable to be used as a natural substitute for formalin or borax for insect repellent, and a wood preservative which has received wide attention in recent years. Therefore, the purpose of this research is to design a device that produces liquid smoke from burning coconut shells from the distillation process, which can increase the amount of liquid smoke produced.
