The study aims at discovering the influence of professional competence, the influence facility and infrastructure on the performance of lecturers, the influence of achievement motivation at Tourism Polytechnic of Makassar. Data collection techniques employed observation, questionnaire, documentation, and interview. The number of samples in this study were 147 people consisting of lecturers and teaching staff with a sample of 114 people. The data analysis technique used is multiple linear regression analysis using the SPSS 22 program to obtain the following research results: (i) based on the statistical calculation results α of X1 is 0.000 less than 0.05 then Ha is rejected and H0 is accepted, which means professional competence X1 turned out to significantly influence the performance of lecturers (Y) at the Makassar Tourism Polytechnic. (ii) Based on the results of statistical calculations, the α value of X2 is 0,000 less than 0.05, then Ha is rejected and Ho is accepted. Thus the infrastructure (X2) significantly influence the performance of lecturers (Y) at the Makassar Tourism Polytechnic. (iii) Based on the statistical calculation results, the α value of X3 is 0,000 less than 0.05, then Ha is rejected and Ho is accepted. Thus the achievement motivation (X3) turned out to have a significant influence on the performance of lecturers (Y). These results indicate that there is a very significant influence between the independent variables X1, X2 and X3 simultaneously on lecturer performance (Y). Thus the first hypothesis which states that professional competence (X.1), infrastructure (X.2), achievement motivation (X.3) simultaneously affect lecturer performance.

This work aims to investigate the performance of the boiler of a power plant in Tello Makassar. The boiler has generated an electricity power of 50 MW in order to fulfil the electricity needed by people in Makassar city. Performance investigation of the steam generator is very important due to the operation of the boiler is a long time since 1971. The methodology in this study uses energy and exergy analysis as well as the entropy generation approach. The methodology will be applied in all the boiler components, namely Combustion Chamber, evaporator, superheater IA, superheater IB, superheater II, air heater I, economizer, and air heater II. The result shows a significant decrease in the efficiency of energy and exergy for superheater II of 28.98% and 21.28% respectively. The performance of superheater I and air heater II shows energy efficiency above 90%, while the exergy efficiency is lower than 50% for both components. The economizer has been in the middle performance by placed the efficiency of energy and exergy in 64.48% and 48.35% respectively. In general, boiler components are working very well by the reach an energy efficiency of 90% on average. However, by applications, the exergy analysis of the performances of the components does not reach 50%. The result of the study also shows that the energy and exergy efficiency of the boiler are 41.96% and 29.36% respectively. Meanwhile, the heat inducted to the steam turbine is 35.98 MW and 15.12 MW by energy and exergy analysis when the plant has been working on 10.3 MW of a load.
