Abstract

Composite is a new engineering material whose main constituent consists of two or more materials. The combination of these materials will obtain better mechanical properties. Apart from that, making composites also has a relatively cheaper price when compared to other materials, especially metal materials. In this research, we created and carried out a comparative analysis of composites between fiberglass (woven roving) and palm fiber which were applied to the prototype body of the Energy Saving Car Contest. The composite manufacturing process in this research uses matrix material (resin), catalyst, fiberglass and palm fiber using the hand lay up method. The variations used in making composites are variations in the number of layers for fiberglass fiber (2 and 3 layers), and palm fiber using 2 and 3 layers with vertical, horizontal and random fiber directions. The results obtained for tensile strength testing obtained the highest value, namely 109.1 MPa (3 layers of woven roofing). Meanwhile, the highest bending test value was obtained at 4.52 MPa (3 layers of woven roofing). In testing composites based on the fiber direction, the highest tensile strength and bending values were obtained for specimens with 3 layers of random fiber direction, namely 11.1 and 1.18 MPa.

Abstract

Haspel or often called cable reel is the item or tool needed to roll the cable. Usually this cable reel is made of wood. However, over time this haspel has changed, especially in the material used, which is made of plastic or polypropyelene (PP) material. This haspel consists of several components including: Flange and barrel reinforced using steel rods. All these components will be assembled and ready for sale. When assembled, the flange components must require a fairly good precision because the material used is plastic, the shrinkage factor plays a very important role when printed with an injection molding machine. At the time of assembling the plastic haspel, there was a failure when the raft product was too tight and there was also a loose raft, this was due to shrinkage in the flange which caused the barrel component to not fit into the router part of the flange. This makes the assembly work a little longer than usual. In this final project, the author takes steps on how to analyze shrinkage defects in plastic materials, especially for polypropylene materials, starting from the injection molding process and then taking product samples with different levels of testing through parameter settings. Different injection times and backpressures will result in different product sizes and shrinkage values. A good melting temperature value is used for polypropylene material with a flange thickness of 6 mm, and a flange diameter of 850 mm ranging from 210°C - 230°C. Shrinkage defects in polypropylene materials certainly exist, and may be greater than polystyrene materials but can be minimized by setting good process parameters. A good and ideal shrinkage value and according to standards occurs at a temperature setting of 220°C backpressure 0.2 Mpa with an injection time of 20 seconds. With constant parameters, starting from the injection speed of 60 mm/s. Injection pressure 18 Mpa and cooling time 250 seconds.

Abstract

The aluminum casting industry has experienced a lot of innovation and creativity to maintain its existence. Metal casting is a process by which hot molten metal is poured into a mold containing hollow pieces or cavities of the desired finished shape. The process of casting with a permanent mold is preheating the casting mold before the casting process is carried out. This is done so that the temperature of the casting mold increases, so that the difference between the temperature of the mold and the temperature of the aluminum to be poured is not too great. This study aims to overcome or prevent hot tearing by increasing the preheating temperature in the mold. The test results show that the preheating temperature of 200ºC does not experience shrinkage in the metal casting results. Whereas at preheating temperatures of 125ºC and 150ºC there are hot tearing defects and there is shrinkage. whereas at the preheating temperature variation of 200ºC there are only shrinkage defects. The results of the vickers hardness test showed that the higher the preheating temperature, the hardness value of the casting product will increase. The highest vickers hardness value was obtained at the 200°C preheating temperature variation of 69.55 HV, while at the 150°C preheating temperature variation, the vickers hardness value was 68.51 HV. and at a variation of the preheating temperature of 125ºC, the vickers hardness value is 67.04 HV. The results obtained from metallographic testing are aluminum 6061. Judging from the microstructure at the 200℃ preheating variation, the dentite grains look smaller than the 125℃ preheating variation and the 150℃ preheating variation. It can be concluded that the higher the preheating temperature, the better the denrite density.

Abstract

Conventional and CNC lathes are one of the numerical components as a production machine for manufacturing purposes that the industry relies on. To get the level of smoothness of a surface plays a very important role in the planning of a machine component, especially concerning the problem of friction, wear, resistance to fatigue as well as for surface roughness is closely related to the function of the component The manufacture of components does not merely have to have a small or smooth roughness value, but must also be in accordance with the functions and requests of the designer. TU 2A CNC lathe has a smaller roughness value (smoother) than the turning results using a conventional lathe. This is evidenced from the results of roughness testing where the smallest roughness value of the TU 2A CNC lathe is 1.27 µm and the smallest roughness value of the conventional lathe is 1.38 µm while the largest roughness value of the TU 2A CNC lathe is 2.68 µm and the surface roughness value for conventional lathes is 2.71 µm. The surface roughness class of the results of this study is in N6 to N8

Abstract

Optimal productivity needs to be supported by the availability of machines that are always ready to produce. The condition that needs to be maintained is that the machine does not stop frequently due to damage and causes the continuity of production to be hampered. According to the Japan Institute of Plant Maintenance (JIPM), the level of machine availability (availability) is said to be ideal when it exceeds 90%. At PT. ATMI Solo, 23.8% of 21 CNC machines still have availability percentage below 90%, namely Salvagnini S4 punching machine (69%), Starrag CF100 milling machine (79%), Trubend 3180 bending machine (82%), milling machine YCM TV 158B (82%), and Trumatic TC 200 R punching machine (89%).The main factor is the low availability of machines at PT. ATMI Solo is high machine downtime due to a breakdown. Therefore, it is necessary to implement Total Productive Maintenance (TPM) to optimize the availability of these machines. The implementation of TPM is Training and Education, Autonomous Maintenance, Planned Maintenance, and TPM in Administration (TPM in Administration), especially in the spare part Logistics section. The implementation of the TPM succeeded in increasing the availability percentage above 90% (based on data from the 2022 General Maintenance Daily Report), namely the Salvagnini S4 punching machine (94.13%), Starrag CF100 milling machine (96.36%), Trubend 3180 bending machine (99, 70%), YCM TV 158B milling machine (99.97%), and Trumatic TC 200 R punching machine (99.88%).
