Abstract

Cigarette filter waste is one of the wastes that is difficult to recycle and has no selling value, so cigarette filter waste is used as an alternative material for making helmet shells. This study aims to determine how a composite material (ie 16% HGM, 76.5% epoxy, 7.5% cigarette filter waste) is used as a basic material in the manufacture of helmet shells. The testing process carried out is the charpy impact test with different specimen thicknesses (3 mm, 4 mm, 5 mm). Based on this study with a thickness of 3 mm, the highest average impact strength compared to other thickness specimens was 0.02868 J/mm2, at 4 mm thickness was 0.01628 J/mm2, at 5 mm thickness was 0.01025 J/mm2 .. In this test, compared with the results of the SNI helmet impact strength test of 0.00972 J/mm2 then all specimens passed the material test for SNI helmets.

Abstract

The pineapple plant is one of the most prominent plants in Indonesia, the value of the pineapple leaf could be said to have no sell or be called a waste. The use of composite materials with natural fiber filtering is growing. Composites are materials made up of two or more different materials. In this study used epoxy particle composites with doubles of the hollow glass microsphere and fibers of the pineapple leaves. In this research conducted a 3 thickness test of 10 mm, 15 mm, and 20 mm. The test results were obtained that projectile-pierced specimens with depth damage after penetrating the succeeding specimens of 58 mm, 10 mm and 4 mm. From the results is obtained, specimens were not safe to use because according the criteria for failure of bulletproof vest from the aspect of penetration is penetration should not exceed from thick vest or can be said sould not a translucent.

Abstract

3D Printing is an additive manufacturing technique that can be used to convert computer aided design (CAD) data and then print it by adding material layer by layer to form a 3D product. One technique or method that is often used in 3D Printing technology is FDM (Fused Deposition Modeling), because this technique is the easiest to use and the cheapest. The purpose of this study was to obtain the optimal process parameters on 3D Printing FDM to the resulting tensile strength. This study uses the Taguchi method with an experimental design used L9 (34) OA. The material used in this research is ABS CCTREE. The process parameters used in this research are nozzle temperature (°C), table temperature (°C), layer thickness (mm) and print speed (mm/s). The strongest tensile strength value is 41 Mpa. Parameters that produce the strongest quality are performed at table temperature (92 °C), nozzle temperature (237 °C), layer thickness (0.22 mm) and Print speed (42 mm/s).

Abstract

Pineapple leaf fiber is one of the plantation wastes that is rarely processed and has a low selling value, Therefore, pineapple leaf fiber is used as a reinforcement for composite materials with an epoxy as a matrix and 16% filler material in the form of Hollow Glass Microsphere which is expected to produce renewable materials that can increase the selling value of the waste.. This study aims to determine how the effect of composite composition on tensile strength and impact of several parameters used. The testing process carried out is tensile test and charpy impact test with matrix and fiber volume fractions, namely, 74%:10%, 12.5%:71.5%  and 15%:69%  with horizontal and vertical fiber directions. Based on this study, specimens with a fiber fraction thickness of 15% with a vertical direction resulted in an average tensile strength of 84.83 MPa and the highest average impact strength was obtained in specimens with the same parameters is 0.1367 J/mm².

Abstract

Composite is the process of mixing or combining two or more materials where the two materials have different properties, the results of the mixture can be referred to as (composite materials). The purpose of this research was to make composite specimens made from epoxy resin, Hgm, balsa wood fiber as natural reinforcement and carried out impact and tensile tests to determine whether the strength of the composite could be an alternative as a substitute for protective Toe caps for safety shoes. The balsa wood used in the tensile test specimen is in the form of sticks with a length of 16cm and a thickness of 3mm which has 3 test parameters, namely 1 balsa stick, 2 balsa sticks, and 3 balsa sticks. As for the impact test, 1 stick of balsa stick with a length of 7.5 cm and a thickness of 3 mm. Keywords: Composite, Balsa wood, Hgm, Epoxy, Impact and Tensile

Abstract

Requirements so that the product can be declared passed and standardized. One of the tests carried out is penetration testing, this test is carried out to determine the mechanical properties of the material being tested. In this research, a test instrument is made for penetration testing, where in this test it can be known directly, what happens to the material being tested when a sharp object is punctured or an impact with a sharp object occurs. The penetration tester identifier is made in the form of a cylinder with a PVC guide pipe with a size of 1 inches. To determine the accuracy of the test equipment, the indenter is dropped on the test material from a certain height, namely 160 cm, for the data collection process by marking the indentation marks and visually observing them. For the indenter material used 4340 aisi steel because the steel can be hardened to a hardness of 50 HRC. In the penetration test equipment there are forces acting. The force is that the indenter has a gravity of 30.9 joules. And the potential energy when the identor falls from a height of 1.6 m is 49.44 joules. And the velocity of the identor when it falls is 5.6 m/s.

Abstract

Light brick is a building material that is still quite foreign among the middle to lower society, the composition of light brick building materials is still quite interesting to research. In some previous studies, attempts to find the optimum composition of light brick mixtures used experimental methods that evaluated the influence of a factor in an experiment. The outcome of a production process can be influenced by a variety of factors. In this study was conducted to find the optimum composition of light brick building materials by applying the Response Surface Methode method. Research shows that the proportion of materials that produce the most optimal water absorption is rice husk (8.5%) and foam agent (0.9%), which is able to produce light bricks with an average water absorption of 50.22%.The results of this study also recommend a general equation to predict the absorption of light brick water when using both compositions of the material, namely: Y = 43,206 - 2.119X_1 - 1,228 X_2 - 8,479 x_1^2 – 2,264 x_2^2 - 13.785X_1 X_2 with X_1 and X_2 respectively is the proportion of rice husks and foam agents, respectively.
