Abstract

Transportation service industries cannot be apart from competitivephenomenon. They, including the train service industry, must be able to compete tosurvive. This transportation competition, air-land-water, causes the decline of ofexecutive class train passengers. This research would find out the service given by PTKAI to its customers in decision making to use transportation service. The data wasprimary data. The technique sampling was quota random sampling, which met datanormally requirements. The result shows that there is an unfavorable relationship betweenimage and quality of service represented by correlation coefficient 0,105. There is alsoan unfavourable relationship between employee’s performance and quality of servicewith correlation coefficient 0,113.Keywords : service quality, image, employee’s performance, customer satisfaction

Abstract

This research was intended (1) to conduct deep examinations on the preparedness of KEK (Special Area for Economic Activity) infrastructures and the related institutions for investors. (2) to conduct the relevant cost-benefit analyses. This research employed quantitative and qualitative approaches. The analyses showed that there were really infrastructure supports (a sea harbor for exports, roads of national class, by pass, a tolled highway, railroads, an international airport and ample electricity), vendor supports (3,339 big- and medium-size industries, 644,000 small industries, a metal industrial center, 524 manufacturers and 873 export-oriented industries) and human resource supports (9 State-owned Colleges, 332 Private Colleges, 782 Vocational High Schools, 19 Private Work Training Centers and 2 State-owned Work Training Centers). Based on an assumption of an average price of Rp. 45,000/m for land and an average cost of Rp. 60,000/nT for filling out 2-meter deep coastal areas, it can be concluded that the recommended project should be continued because it has positive cashflows and net-cashflows as well as relatively high B/C ratio (19 kali). However, it has a relatively long waiting time for ROI (at least 25 years) and small IRR (7.7%).

Abstract

The method of calculating the volume of fuel oil using standard 15⁰ C is one of the methods used internationally in calculating the volume of handover transactions. To standardize the calculation of fuel volume in various weather conditions, there are several fuel calculation methods, namely the Observed calculation method, th calculation method in standard 15⁰ C, the calculation method in barrels and the calculation method in long tons. For the calculation method that is suitable for use in Indonesia is the standard volume calculation method of 15⁰ C, so that in extreme weather conditions or temperature differences, the volume calculation can still be accommodated even though the difference is very significant. In this case, we take a sample calculation of the volume of MFO fuel oil through the Moto Tanker at the Belawan PLTU Jetty Port. From the measurement results, the overall volume was 4,802,983 liters of Observed, and at a standard volume of 15⁰ C, a volume of 4,747,268 liters of standard 15⁰ C was obtained. From these results, the difference between the Observed volume and the standard volume of 15⁰ C was 55,715 liters or equivalent to 1.16% of the volume Observed. So it can be concluded that the standard volume value of 15⁰ C is 1.16% smaller than the Observed volume and the standard volume of 15⁰ C will always be lower than the Observed volume. For this reason, the standard volume calculation method of 15⁰ C is a very suitable method for calculating the volume of fuel oil.
