Abstract

Agglomerative Clustering is one of data mining methods to get a cluster in form of trees. In order to achieve these objectives, we used two agglomerative methods such as Single Linkage and Complete Linkage. Searching for nearest items to be clustered into one cluster also needs a similarity distance to be measured. We used Euclidean Distance and Cosine Similarity for measuring similarity distance between two points. The factors that promote high levels of accuracy depend on the pre-proceeding stage for clustering process and also affect the results obtained. Therefore, we conducted research through several stages: pre-processing such as ETL, normalization, and pivoting. The ETL process consisted of removing outliers using IQR method, data-cleaning and data-filtering processes. For normalization, we used Min-Max and Altman Z-Score methods to get the best normal value. The results of this research demonstrate that the highest accuracy occurs when using the Complete Linkage with Min-Max and the Euclidean method with the average purity of 0.4. The significant difference is observed when using the Z-Score and Cosine Similarity methods; the average purity is around 0.11. Besides, we found that the system also could not predict the customers’ preferences in buying goods for the next period. Another result in the research is that transactional data in a company are not good enough to be clusterized.

Abstract

The brake is a major and vital component to slow down and stop a vehicle. If the brake malfunctions, it can cause a fatal accident or seriously injure either passenger or other road users. That is one reason why research is conducted to improve the capability and reliability of vehicle braking systems. The thermo-mechanical properties of the material for better disc brake components have been investigated. Some geometrics of the disc brake design models have also been studied to determine the heat distribution that occurs during braking. However, brake failure cases still occur frequently. Most of the brake failures are preceded by the occurrence of overheating when the vehicle is braked continuously on a declining road. This indicates that the heat dissipation system during braking does not work well. This study focuses on designing an unconventional brake system, that uses an active cooling system. Under conditions of large braking loads, the brake system will actively cool down by spraying water on the caliper so the brakes will not experience overheating. The design of this system consists of temperature sensors mounted on the caliper, an over-temperature control unit and also a cooling unit. The design is implemented on a four-wheel vehicle brake model. The increase of caliper temperature at the time of braking is simulated by putting the temperature sensor on the Bunsen burner. The results of this study shows that at various levels of temperature increases the system works very well.

Abstract

The analysis of the mixture of anthouse plant (Myrmecodia pendans) and red pepper vine (Piper ornatum) in H2SO4 1M solution had been studied by weight loss, Electrochemical Impedance Spectroscopy (EIS), Fourier-Transform Infrared Spectroscopy (FTIR), and Spectrometer test. The Myrmecodia pendans and Piper ornatum were chosen because they contain antioxidants that can inhibit the corrosion rate. The specimen used in this study was API 5L Grade B steel in H2SO4 1M solution. The compositions used in this study were 100% MP : 0% PO, 75% MP : 25% PO, 50% MP : 50% PO, 25% MP : 75% PO, and 0% MP : 100% PO (MP: Myrmecodia pendans, PO: Piper ornatum). FTIR testing result shows that a passive layer was formed by O, H, and N bonds. The weight loss method shows that the highest efficiency of 52.43% was achieved by 50% MP : 50% PO mix composition. Polarization testing shows that the corrosion rate decreased drastically with the addition of 50% MP : 50% PO mix composition, i.e., from 36.32 mpy to 7.93 mpy, due to the passive layer formed on the steel surface. EIS results show the presence of resistance solution (Rs), charge transfer resistance (Rct), and CPE. The adsorption free energy value of the mixture of Myrmecodia pendans and Piper ornatum was −10.02 kJ/mol and it was a physical adsorption.

Abstract

In factory works, there are systems that need to be followed in order to create a well-ordered process such that Just In Time (JIT) production can be reached. The lean manufacturing principle is one of the solutions for sustainable factory system. Within the lean manufacturing system, there are many tools that can be applied for sustainability and improvement. In this paper, Kaizen, the Japanese business philosophy as one of the lean manufacturing principle tools, is applied to give an improvement in reducing production cost. It is done by continuous observation, note, and analysis of time consumption required by the production line. A new Kaizen analysis from a new point of view is applied by comparing the impact of adding operator to the production line to the Over Time (OT) cost and renewing part of the machine-tool mapping for faster Takt Time (TT). Kaizen activity was successfully analyzed. It shows that the production Cycle Time (CT) can be deducted by 0.5 seconds which will reduce the production revenue cost by 10.8%.

Abstract

PT. X is a multinational company that works in the consumer goods sector. PT. X has many departments and one of them is the Human Resources (HR) Department whose role is to maintain all of the employees under PT. X. The HR Department also has some subfunctions. One of them is HR Services. Employees that work with PT. X are divided into two categories: monthly employees and daily/piece-rated employees. One of the processes that HR Services provides for the daily/piece-rated employees is ePAF daily/piece-rated, which can be monitored by a verification process. If an ePAF is not verified, then it is possible for the ePAF process to be denied and that is a waste that can cause over-processing for HR Services. There were 750 ePAF denials in 2016 with an average processing time of 1.78 hours needed to resubmit each process. An analysis was done using a Pareto Chart and Fishbone Diagram to reduce the time wasted and to look for countermeasures for each of the root causes. The Pareto Chart shows three major problems occurring. These are: errors in the closing date, errors in the transaction date, and errors in the supporting document. The root causes of the problem come from human error, method errors, and system classification errors. The solutions proposed are expected to reduce the numbers of ePAF denials by around 51.2%.

Abstract

Design is not a lasting component within a web application. There will come a time when the design is outdated and requires a new form of styling. However, in order to implement the new design, one or more developers are needed to modify the code of the application. The process will use a considerable amount of resources and time that might be more valuable to use for other more important cases. That is why the idea of creating a Design Management System (DMS) surfaced. DMS is created for talent.gamehouse website so that an individual with no knowledge in web development can alter the styling according to his/her preference. The application will also help developers who work on the website to decrease the time needed to do the design implementation. The process is done through several phases. The first phase is to inject a server-side programming language, such as PHP, Python, and Ruby to the Cascading Style Sheet, which is a presentation document that consists of styling properties for a website. The second phase is to create a database for the styling properties, so that the data is stored in a server instead of the CSS. The last and most crucial phase of the process is to create a function where a styling property can be modified using an SQL query. The query will alter the property to the user’s liking. These phases are all generated through a front-facing site which the users will interact with. The site will be created using Hyper Text Markup Language (HTML), complemented with additional frameworks to enhance the user’s experience. The application was tested through a usability session with one of the stakeholders of the application and generated a positive outcome for the fully-functional end result.

Abstract

With the increasing market competitiveness, it is crucial for company to remain effective and efficient in its Operation Management. Production process is one of major areas where company seeks to improve its production capability in order to remain competitive. The research was a case study in a door fabrication line. The production process is a job shop process type which consists of several inter-linked and inter-dependent sub-processes with shared resources. The study used simulation methodology and Simio software to better understand and analyze the complexity of the process. The study fed few controlled and uncontrolled input variables into the simulation models and analyzed on how to improve some output/response variables. Six scenarios were analyzed during experimentation leading to the best scenario 7 giving improvement in term of crew utilization, average time, and number of entity in the system. Besides giving recommendations to the studied company, the study also successfully demonstrated on how simulation can be used to mimic different kinds of process logic in a job shop production process.
