Abstract

The barge backhoe deck is planned to be modified to add length so that analysis is neededregarding the strength of the structure, considering that most coal loading and unloading processestake place on the backhoe deck, so the safety of the backhoe deck structure is very important. In thisstudy, we will find out how much stress occurs on the backhoe deck by using the Finite ElementMethod as the media of analysis.From the results of the simulation and analysis it is known that themaximum voltage that occurs when the backhoe is not operating is equal to 24 MPa, and when thebackhoe is operating that is equal to 27.43 MPa. The maximum deflection when the backhoe is notoperating is 60.99 mm, and when the backhoe is operating that is 68.6 mm. Factor of safety when thebackhoe is not operating is 9.6 and when the backhoe is operating is 8.5.Based on the simulation themaximum voltage value is still below the permit voltage in the manual calculation, namely 166 Mpa.The deflection value of the simulation results is also still below the maximum deflection value that ispermitted in the manual calculation of 70 mm. The factor of safety value according to BKI can beconcluded that the construction of the backhoe deck is declared safe in loading when the backhoe isnot operating or when the backhoe is operating because it meets the safety factor requirements thatthe safety factor value must be more than 1.

Abstract

Indonesia has a lot of livelihoods, especially in industry. Because the Indonesian people are very numerous, the production each year will increase, therefore every producer must be able to overcome every need that consumers want. The manufacturing field is most needed in every industry because every product manufacture must not be separated from the manufacturing process. In a worksheet there must be a hand work tool to facilitate or tidy up a final process. In this case the viscera function as a tool for clamping workpieces is very important. Ragum is a clamping device to clamp the workpiece that will be carried out by the milling process. With the vise, the workpiece can be tightly clamped so as to facilitate the processing process and the results of a process will be maximized. In this Final Project, a maximum stress strength analysis will be carried out on one of the Hydraulic Rigs with the aim that the Raft can be more efficient and operate optimally. The study conducted on this hydraulic formula is expected to be able to overcome problems that often occur in the manufacturing process in the field of production. So that the operator knows more about the work of the hydraulic vise and can operate optimally, and the production work is not hampered due to damage to the vise. In the end, the hydraulic vise will be able to be used longer than the vise that is used carelessly and quickly damaged.

Abstract

In the past one year, the problem of critical defects is the most dominant problem. With a percentage of 46% of all problems. This study aims to determine the factors that cause the bottle to leak and to find an effort to reduce the level of leaky bottles in the blow molding department's bottle production process. The method used in this study is Six Sigma which includes five stages of analysis, namely DMAIC (Define, Measure, Analyze, Improve, and Control). The approach used to improve the process. Each stage of DMAIC is done by carefully analyzing and maintaining the process. The results of this study indicate that the factors causing leaky bottles analyzed with FTA are problematic valves, air settings are not normal, blow pins are not centered, loose switch limit bolts, no checking rules, new technicians, and no defective mouth product reference . While the effort that must be done is changing the valve, the central pressure is increased to 7.5-8 bar, setting the blow pin to the center, changing the limit switch bolt, making the rules at the beginning of shift shifts, holding regular training for technicians, and making leaky product references.

Abstract

Plastic is a human need in everyday life, one of which is as a place to wrap food and drinks. The increasing level of public consumption, the more plastic waste produced. Waste from plastic is very difficult to decompose naturally. In order to overcome this, of course, we need a way to process the plastic waste into more useful things and also have benefits for the community, one way is to recycle plastic waste into fuel, which is fuel in the form of oil. But in making a new innovation, a tool is needed that can transform a waste into something that is beneficial to society in general. One of them is by distillation or distillation. A tool used to separate chemicals based on differences in speed or ease of evaporation or volatility of materials. In this distillation, the mixture of the ingredients boils so that it evaporates and the steam is then boiled back into liquid form. Substances that have a lower boiling point will evaporate first. Later this steam will turn into oil using the help of a condenser. Where the steam entering the condenser will condense and form water grains. Which will later turn into oil. The oil produced through this distillation process with PET and PP plastic as much as 500 ml for 5 kg of plastic.

Abstract

One of the problems of PT. YRS (Confident of Achieving Success) is the damage of red ginger seedlings due to a long period of time during the expedition so that the seeds of ginger decay. One of the decay factors is the high water content. To minimize damage to ginger seeds, red ginger seeds must be aerated (dried) for 1 week in 200 kg. The process is considered less efficient because it still uses manual methods. Therefore, an integrated machine is needed. This red ginger seed drying machine uses a fan blower system as an introduction to hot air with an air flow rate of 29 cfm and uses an automatic system as an electric controller. This ginger seed drying machine requires energy of 790 j / sec or 790 watts. The results in this study are that the red ginger seed drying machine can work well and can achieve drying of ginger seeds with an average moisture content of 83.17% where the moisture content is included in the specification requirements of PT. YRS within 45 minutes. This drying machine speeds up the drying process than before and cuts the operational costs of PT. YRS so that by using this tool PT. YRS can reduce expenses.
