Abstract

In industry field, designing products that meet the criterias and expectations of the consumers is a must. PT Pura Mayungan as an industry panel company obtained a Cyber Project which required a particular project management system. In the meantime, the regulation and monitoring of all activities related to the cyber panel have not been well integrated as in the activities of inventory, purchasing, and sales towards the cyber project focusing. This causes difficulties in generating information needed by the management. Thus, a project management system was built to assist in the operation management activities including purchasing, inventory and sales. Besides, there was a need to build a computerized information system specifically for handling the calculation and recording of inventory and transactions to improve company performance. In this research two methods were implemented: analysis and data collection through literature evaluation. This research concluded that the lack of regulation and monitoring would bring a lot of difficulties in delivering information.

Abstract

Slum areas are likely found in many cities in Indonesia although the government through the Ministry of Public Housing have rolled several programs to alleviate its existence. One example of slum areas is found in Payakumbuh, West Sumatra, where its land are mostly owned by local traditional folks knowned as ‘ulayat land’. A huge amount of poor houses are built on rented ulayat land. Regarding to the rent status, the housing arrangement on the area faces difficulties. Therefore, this article would like to give an overview of problems in the slums arrangement in Payakumbuh as well as giving some concepts for dealing with the problems associated with such land status owned by adat.

Abstract

Every industry needs IT to improve their business and give faster service to customer. The fast growing of social network (Facebook, Twitter, MySpace, LinkedIn) and Smartphone (Blackberry and iPhone) in Indonesia indicate that Indonesian people are already familiar with high technology and it is the right time to introduce new technology in Indonesia. The problem is, the usage of IT-based system in Indonesia is not optimal. Nowadays, people want to do almost everything faster and more convenient using technology. We know thatuntil now, there are a lot of situations that make people queue or wait to get their need. In this kind of situation, we need something that will change the way to do business, that is in effective and efficient way. NFC (Near Field Communication) is considered suitable as the solution. NFC technology as one of payment systems can increase competitive advantage of the company which implements it and will make it a leader in the industry. This new technology could attract customers, especially Indonesian people in big cities who want to do their transaction in quick and efficient way. NFC is already implemented in Korea and USA as substitution of e-wallet that can help people to make transactions easier and faster. I believe NFC can be implemented in Indonesia to make new trend of doing business.

Abstract

Compensation is everything that will be received by a person as remuneration for the work she/he has done, either directly or indirectly. Assessment of labor productivity is almost always automatically associated with the rules and regulations of individual salary increases and bonus distribution. Result of the analysis indicates work environment played a very important role for the improvement of labor productivity with r2 = 0.933 (93.3%), and t 8.158 and t table 0.30. Result of the hypothesis testing of the effect of compensation onemployee and lecturer productivity (r2=0.933 or 93.3 % with t 3.729 and t table of 0.30) means compensation had a very strong influence. Result of the hypothesis testing of the effect of competence on employee and lecturerproductivity shows r2= 0.933 or by 93.3%, with t 4.014 and t table 0.30. Result of the analysis shows the correlation between work environment and labor productivity is equal to 0.769, means it had a fairly high correlation. The correlation between compensation and labor productivity by 0.482 is moderate. The correlation between competence and labor productivity by 0509 is moderate. The determination determination is equal to 0.933 means that employee and lecturer productivity was influenced by work environment, compensation, and competency in the amount of 0.933 (93.3%); while the 6.7% remaining was influenced by other variables outside the research. The regression function resulted from the analysis is Y = -0.026 + 0.548 X1 + 0.260 X2 + 0.281 X3.

Abstract

Efficiency or the running time of an algorithm is usually calculated with time complexity or space complexity as a function of various inputs. It is common to estimate their complexity in the asymptotic sense, i.e., to estimate the complexity function for arbitrarily large input. Brute-force algorithm is the easiest way to calculate the performance of the algorithm. However, it is not recommended since it does not sufficiently explain the efficiency of the algorithm. Asymptotic estimaties are used because different implementations of the same algorithm may differ in efficiency. The big-O notation is used to generate the estimation.

Abstract

This research aimed to determine the needs and wants of production and management team to improve the machine and performance maintenance. Voice of the Customer (VOC) method was used to capture the needs and wants of production and management team. Meanwhile, the method of Quality Function Deployment (QFD) was used to translate the needs and wants of production and management to the technical requirement that should be done to improve machine and performance maintenance. Moreover, Total Productive Maintenance (TPM) was a part of technical requirement. From the result, it is known that long breakdown machine, huge inventory of spare part, and high cost of maintenance become the first of priority of maintenance team to achieve customer satisfaction. To develop the performance maintenance, the company should standardize the procedure, identify the critical spare part, reduce the time to purchase critical spare part, and increase lifetime of spare part.
