Abstract

This research aimed to find the best rainfall probability model and planned rain intensity using the Mononobe formula for 11 rain stations in Serang Regency. Annual rainfall data is processed and evaluated as secondary data using the rain data consistency test method, the Gumbel probability distribution, the Normal probability distribution, the Log Normal probability distribution, and the Pearson Type III Log probability distribution. The consistency test results reveal that the rainfall data is consistent. The Gumbel probability distribution is used to examine the design rain intensity based on the analysis. This study is intended to guide estimating the design rainfall intensity to develop the design flood discharge and run-off calculations. Suggestions for future research include improving the accuracy of rain data processing and making longer-term data available to provide a more accurate frequency analysis

Abstract

The use of composite materials in brake pads is becoming increasingly popular due to their high-performance characteristics, including good thermal stability, high wear resistance, and low noise generation. However, the development of new composite materials that offer even better performance is still an ongoing research area. In this study, the composite was made by hand layup method using epoxy resin as matrix material, with rice husk, Al2O3, and Fe2O3 as reinforcing materials. The composition of the composites was varied by changing the percentage of the reinforcement materials. The composites were then subjected to several characterization tests, including density, hardness, flexural strength, thermal analysis, Scanning Electron Microscopy (SEM), TGA/DSC, and wear testing. The test results showed that additional reinforcement materials to the epoxy resin matrix improved the mechanical properties of the composites. Overall, the study demonstrates that a hand layup method is a viable approach for preparing brake pad composite materials and that the addition of rice husk, Al2O3, and Fe2O3 can improve the mechanical properties of the composites. The best properties produced in this research were found in one of the specimens which used epoxy, rice husk, Al2O3, and Fe2O3 with a composition of 50 wt.%, 20 wt.%, 15 wt.%, and 15 wt.%. However, the addition of rice husk also provides wear resistance and thermal stability. This study contributes to the Sustainable Development Goals (SDGs) by advancing innovation, promoting sustainability, and reducing emissions in automotive industry applications.

Abstract

This research literature review that reviews the literature on the factors that influence innovation variables has been a lot, but those that review innovation performance variables are relatively still not much. Therefore, the literature review in this study aims to investigate the factors that affect innovation performance in manufacturing companies, as well as factors that act as mediation and moderation. The Systematic Literature Review (SLR) method is used in this study to analyze and review or look back at findings that are systematically identified based on previous research evidence related to factors that affect the innovation performance of manufacturing companies. Research data was obtained from Google Scholar with a time span of 2015-2023. Findings on journal searches found 304 articles. Based on the search for articles that discuss and focus on factors that affect the specific innovation performance of manufacturing companies, 25 articles were found. The article is used as a data source and will be examined in more depth. The results of the research found that (1) Various factors affect innovation performance in manufacturing companies; (2) Several factors can mediate and moderate exogenous (independent) variables on the innovation performance of manufacturing companies; and (3) Various theories have been used in research on the innovation performance of manufacturing companies. Therefore, manufacturing companies can use the above variables as factors that can be used to improve innovation performance to increase productivity, effectiveness, and can drive growth for manufacturing companies. These findings can be used as reference material for further research on variables that are able to mediate and moderate the relationship between exogenous variables on innovation performance in manufacturing companies and the theory used.

Abstract

In the industrial era 4.0, the automation system technology used is growing rapidly. Automation systems in the industry are very useful, especially in reducing production time. One of the tools that can be used to simulate production in an industry is the Modular Production System (MPS). MPS itself consists of several stations to simulate the production process on a small scale. In a production system, of course, a system is needed that can detect abnormal workpiece conditions. This system will be driven by a Programmable Logic Controller (PLC). This system will be placed at the distribution station. The rejection system in MPS is needed because, in MPS there is still a manual process, namely in the process of inserting workpieces into the stack magazine. with this manual process, it is likely that workpieces with abnormal conditions will be processed by MPS. This condition is unlikely to be processed further to the pick and place station. Therefore, objects with abnormal conditions must be separated by this rejection system. There are 2 methods used to conduct this research, namely using the 5/3 valve and the positive stop method. Data collection from both methods is done by experiment. From the experimental results of the two methods, it can be seen that the best method used for this system is the positive stop method. This method is the most appropriate method because it can produce a very accurate swivel arm stop position. From the data obtained, using the 5/3 valve method with a pressure of 4 bar the swivel arm stop position ranges from 22.4 cm to reach more than 25.8 cm, and at a pressure of 5 bar the swivel arm height ranges from 25.8 cm to more. By using the positive stop method the swivel arm stops exactly at the specified swivel arm height because the swivel arm is held by the pneumatic cylinder.

Abstract

Modular Production System is a station unit consisting of industrial components in the form of pneumatic and electrical components controlled by a Programmable Logic Controller which is directed for industry-oriented vocational training. In a Modular Production System, there are several types of stations, one of which is the pick and place station which consists of two modules, namely the pick and place module and the conveyor module. This design discusses the optimization of the design of the top cover feeding unit at the pick and place station because the top cover is dislocated every time there is a change in position when the vacuum sucks the top cover. This design optimization is done by redesigning the feeding unit slider. By doing this optimization, it can make the feeding unit accommodate the top cover where it should be and improve the process capability of the system. The results of this optimization are determined based on the process capability values, before optimization the resulting values were 1.0417 for Capabiity Process and 0.77 for the index. Then after design optimization, the values are 3.402 for Capabilty Process and 6.396 for the index and produce a total force of 0.205 N by using a slider feeding unit tilt angle of 14o. This tilt angle was determined as the most optimal angle because it resulted in the least system failure.

Abstract

Twin wire arc spraying (TWAS) is a thermal spray process that is widely used in various industries. Nevertheless, the impact of repeated sandblasting on the coating characteristics of FeCrBSiMn coating created using the TWAS technique has not been extensively researched. Therefore, this study aims to investigate the influence of repeated sandblasting on the properties of the FeCrBSiMn coating layer created using the TWAS process. The study used stainless steel 304, 75B, and FeCrBSiMn as the substrate, bond coat, and top coat materials. The substrate materials underwent sandblasting with a repetition of 1, 2, and 3 cycles before the coating procedure. The coating's quality in this study was assessed using surface roughness, thickness, hardness, corrosion rate, bond strength, and SEM (Scanning Electron Microscope) examination. The findings of this investigation indicate that the sandblasting treatment substantially elevates the surface roughness of 304 stainless steel substrates. As the substrate surface becomes rougher, there is an increase in the percentage of porosity and unmelted material, as well as an increase in the thickness of the coating layer. Furthermore, the hardness of the resulting coating layer diminishes. Specimen A exhibited superior qualities in comparison to the other specimens. The coating layer on this specimen has a percentage of unmelted material and porosity, thickness, hardness, and adhesion of 7.122%, 0.125 mm, 1081.6 HV, and 14.5 MPa respectively. This investigation's results indicate that the substrate material's corrosion rate (x 10−6 mmpy) is 3648.6, which is lower than the corrosion rate of specimen A, which is 37.802.
