Abstract

Supply chain management plays an important role in enhancing the efficiency and effectiveness of manufacturing industry business process. In this research, the problem is taken from a sales division in a company in determining the optimal sequence when delivering goods into nine cities. This problem is oftenreferred as travelling salesman problem. This problem is considered important since the optimal sequence can cut off operational cost. Creating an artificial intelligence for the company in determining the location and the optimal sequence of delivering goods is the main objective of this research. A genetic algorithm is utilized to determine the location and the optimal sequence. While for processing the data and concluding the result, researcher designed a Java-based application that provides the capability of automatic computing. The result of this computation is a sequence of locations with a fitness number for each. The best fitness number for the sequence location will be used for the final result and the conclusion to answer the company?s problem.

Abstract

Window is one of building components that is directly related to lighting and ventilation. Currently a lot of vertical housings pay less attention to the design of energy-efficient windows. This study aims to find energy efficient windows that are applicable to vertical housing. Surveys on some vertical housings in Jakarta was conducted and environmental simulation programs using CFD and Ecotect was used to explore and analyze the performance of windows for natural lighting and ventilation and further developing of energy efficient windows. The result showed that the Jalousie windows mounted on the center of wall facing out and two louvers above the entrance and upperside of walls in the opposite side of rooms, combined with openings at the bottom of doors are able to create optimum cross ventilation. The resulted wind speed within the range of 0.15 to 0.12 m/s is enough to make comfortable air flow effect, and the average natural lighting of 200 lux is adequate forresidential activity.

Abstract

The use of additional material as ingredients in the manufacture of concrete mixes is increasingly growing. The material used is also increasingly varied, depending on the expected results. This research aims to know the influence of the addition of coconut fibres material with percentage of 1,5 %, 2 %, 2,5 %, and 3 % as an alternative to the strength of high-quality concrete. Research methods done by producing cylindrical and beam concrete samples for testing against the force then conducted concrete. Furthermore, the analysis has been done and the results of testing and comparing the respective strength of the composition of concrete produced. Based on the test results of data concrete cylinder compression strength and tensile strength concrete beams, it was concluded that the increasing of compressive strength up to 9% can be reached by use of additional material coconut fibers 1,5%and increasing of tensile strength up to 19,7% can be reached by use of additional coconut fiber 2%. Therefore, the additional coconut fibers on concrete mixture has strong relationship to increase tensile strength of high strength concrete.

Abstract

The objectives of this study were to determine the effectiveness of K-440 haul trucks based on Overall Equipment Effectiveness (OEE) calculation, to find out the main factors that caused the ineffectiveness of K-440 haul trucks based on fishbone diagram and Failure Mode and Effect Analysis (FMEA), and to analyze the proposed implementation of appropriate improvements to overcome the main problems of K-440 haul trucks. The method used was the mixed method, and the type of research was descriptive. The analysis methods used were OEE, fishbone diagram, and FMEA. The results show that the average effectiveness of the three K-440haul trucks is still far below international standards, which is 44,99%. The material is a significant factor that causes low OEE based on fishbone diagram analysis. There are five problems based on the Risk Priority Number (RPN) critical value from FMEA analysis, namely transmission which is not functioning properly, worn brake lining, unrotated propeller shaft on the shaft, cracked brake drum, and broken spring. Then, the implementation of eight pillars of Total Productive Maintenance (TPM) is proposed in overcoming the main problem of K-440haul trucks. Based on these results, the company needs to implement eight pillars of TPM and carry out OEE calculations regularly.

Abstract

Nowadays, one of industrial main problems is the flexibility of machines to be customized since they are designed based on certain standard. This research develops software for CNC (Computer Numerically Controlled) machine in order to execute the Newton Interpolation using Python. The platform used in the CNC machine is EMC (Enhanced Machine Control) and GUI (Graphical User Interface) AXIS on the operating system Linux Ubuntu. The Newton interpolation is used to create a curve based on several point determined by user. By converting this curve into G-Code, which could be read by CNC machine, the machine can move according to curve designed by user. This research is an initial study to customize the CNC machine and will continue to fulfill the user needs. This research obtained a program that is able to run well up to 4 input pairs. The higher number inputs will cause the oscillation in the interpolation curve.

Abstract

The success of Japanese companies in improving productivity is because they have a culture and a high work ethic to the application of KAIZEN management system. One such application is the Cultural 5S (Seiri, Seiton, Seiso, Seiketsu, Shitsuke). In the Astra group, 5S is known as 5K2S (Order, neatness, cleanliness, sustainability Discipline, Safety, and Service). This study aims to assess the success of the application of the system 5K2S of PT. Andesen Jaya Plastik relating to opportunities for productivity. The method used isquantitative method with a descriptive study. The type of data used is primary and secondary data. While the techniques used in collecting the data are interviews, questionnaires, and literature studies. The number ofrespondents was 31 employees. Analysis of the data used is descriptive and multiple linear regression analysis. The real success rate reachs 82.24% at the stage of familiarization (effective) and they have not yet advanced tothe next stage (prevention). The response of employees is between the Agree and Strongly Agree that is 4.11 point. The correlation between 5K2S to the opportunity of significant Productivity Improvement is Seiri/Order,Seiso/neatness, and Seiketsu/Sustainability.

Abstract

Information Technology (IT) is increasingly progressing. Nowadays, the success of a business of the organization/company is highly dependent on the IT infrastructure used. Therefore, organizations/companies have to manage their IT service to be optimal to their customers. Looking at this matter and the increasing dynamics of XYZ University, then Data and Information System Center (Pusdatin) - an IT provider of XYZ University began implementing IT Service Management (ITSM) from 2013 using the latest version of Information Technology Infrastructure Library (ITIL), namely ITIL v3 as a framework for implementing ITSM in its business processes. However, along the way, there are still some problems happen in Pusdatin in order that ITSM can actually support and align with the objectives of XYZ University. Through this paper, the authors want to explain how the implementation of ITSM at Pusdatin, identify the problems related to the implementation of ITSM, and provide the solutions for each problem. The methods used are direct observation to Pusdatin, conductan interview with the Head of Pusdatin and Staff of Pusdatin, and also perform a literature review of books and papers that discuss about ITIL. The result of this research is that ITSM process of Pusdatin generally works quite well but there are still some shortcomings because ITSM is not 100% implemented in all areas.
