(S1) Faculty of Economics and Business Management and Accounting Study Program, with a total population of students who are active in the Even Semester of the Academic Year 2020/2021 as many as 1148 students. The number of samples taken using the Slovin formula and an error rate of 5% (0.05), obtained a sample of 297 students. The distribution of the questionnaires was carried out offline and online (google form).Stages of research by conducting observations, grouping observational data, searching references/literatures, making frameworks and hypotheses, determining data collection techniques, making research instruments or questionnaires, distributing questionnaires both offline and online (google form), analyzing data using the Structural Equation Modeling (SEM) with a computer tool Lisrel 8.70 program. The steps of Structural Equation Modeling (SEM) carried out by Confirmatory Factor Analysis (CFA), model identification, and Modification of the Model as well as the Goodness of Fit Index.The results showed that the coefficient of the effect of work ability on performance was 0.68, and the t-count value was 7.91. Because the value of t arithmetic is 7.91 > 1.96, then work ability has a significant effect on employee performance. Thus, it can be interpreted that the higher the work ability, the higher the employee's performance. The value of the coefficient of the influence of motivation on performance is 0.20, and the t value is 2.87. Because the t value is 2.87 > 1.96, motivation has a significant effect on employee performance. Thus, it can be interpreted that the higher the motivation, the higher the employee's performance. The coefficient value of the effect of work ability on service quality is 0.82, and the t-count value is 8.62. Because the value of t count is 8.62 > 1.96, the work ability has a significant effect on service quality. Thus, it can be interpreted that the higher the work ability, the higher the service quality. The value of the coefficient of the influence of motivation on service quality is 0.16, and the t-count value is 2.45. Because the value of t count is 2.45 > 1.96, then the effect of motivation on service quality is significant. Thus, it can be interpreted that the higher the motivation, the higher the service quality. The coefficient value of the effect of performance on service quality is 0.46, and the t-count value is 5.72. Because the t value is 5.72 > 1.96, the direct effect of performance on service quality is significant. Thus, it can be interpreted that the higher the performance, the higher the service quality. The value of the coefficient of the effect of work ability on service quality through performance can be seen from the magnitude of the indirect effect of work ability on service quality through performance of 0.32 with a t value of 8.62 > 1.96. This shows that motivation is able to be a mediating variable by 32% for the relationship between work ability and service quality. While the value of the coefficient of the influence of motivation on service quality through performance can be seen from the magnitude of the indirect effect of motivation on service quality through performance of 0.08 with a t value of 2.45 > 1.96. This shows that performance is able to be a mediating variable of 8% for the relationship between motivation and service quality Keywords: Work Ability, Motivation, Performance, Service Quality

Abstract

High Pressure Adsorption Isotherm of CO2 on Activated Carbon using Volumetric Method. Adsorption system is ones of the most effective methods for CO2 separating with other substances that produced from the burning of fossil fuels. In the design for that application, beside of characteristics of porous material (adsorbent) data, CO2 adsorption data on the adsorbent (kinetic and thermodynamic) are also needed. The aim of this research is resulting isothermal adsorption data at pressures up to 3.5 MPa by indirect methods (volumetric method) at isothermal temperature of 300, 308, 318 and 338 K. Adsorbent that used in this research is activated carbon made from East of Kalimantan coals by physical activation method (CO2) which is the surface area of activated carbon is 668 m2/g and pore volume is 0.47 mL/g. Carbon dioxide (CO2) that used in this research is high purity carbon dioxide with a purity of 99.9%. Data from the experiment results then correlated using the Langmuir and Toth equations model. The results showed that the maximum adsorption capacity is 0.314 kg/kg at 300 K and 3384.69 kPa. The results of regression of experiment data using Langmuir and Toth models were 3.4% and 1.7%.

Abstract

A dynamic mathematical model for a new structure of precision air conditioning (PAC) has been developed. The proposed PAC uses an additional secondary condenser for relative humidity regulation compared to a basic refrigeration system. The work mechanism for this system and a vapour-compression cycle process of the system are illustrated using psychrometric chart and pressure-enthalpy diagram. A non-linear system model is derived based on the conservation of mass and energy balance principles and then linearized at steady state operating point for developing a 8th-order state space model suited for multivariable controller design. The quality of linearized model is analyzed in terms of transient response, controllability, observability, and interaction between input-output variables. The developed model is verified through simulation showing its ability for imitating the nonlinear behavior and the interaction of input-output variables.

Abstract

The utilization of waste heat in a power plant system—which would otherwise be released back to the environment—in order to produce additional power increases the efficiency of the system itself. The purpose of this study is to present an energy and exergy analysis of Kalina Cycle System (KCS) 11, which is proposed to be utilized to generate additional electric power from the waste heat contained in geothermal brine water available in the Lahendong Geothermal power plant site in North Sulawesi, Indonesia. A modeling application on energy and exergy system is used to study the design of thermal system which uses KCS 11. To obtain the maximum power output and maximum efficiency, the system is optimized based on the mass fraction of working fluid (ammonia-water), as well as based on the turbine exhaust pressure. The result of the simulation is the optimum theoretical performance of KCS 11, which has the highest possible power output and efficiency. The energy flow diagram and exergy diagram (Grassman diagram) was also presented for KCS 11 optimum system to give quantitative information regarding energy flow from the heat source to system components and the proportion of the exergy input dissipated in the various system components.
