Abstract

The purposes of employees training are to improve, develop, and enhance their skills. In an organization, the scoring of employees’ performance has very essential role in making decision effectively related to the whole process of human resource management. This research purposes to reveal how far the training influences the performance of employees of BMT Sidogiri in Surabaya and SidoarjoThis research used quantitative approach with saturated sampling method (atechnique of sampling if the entire member of population is used). Consequently it is called census research. It investigates 34 employees who work as account officer. Data collected with questionnaires and analyzed with multiple linier regression.The result of this research shows the human resource training variable simultaneously and reliably can influence the employees’ performance based on the result of F test is 65,390 with significance level is 0,000. The contribution of human resource training is 92.1% with the rest is the other variables. Partially, all human resource variable influences to the employees’ performance according to t test result (the each level of training instructor variable, training participants variable, training method, training material, and training facility is less than 0,05). Training facility is the dominant variable regards to the employees’ performance with 0,374 beta level.

Abstract

The counter-rotating wind turbine (CRWT) represents a novel development in horizontal-axis wind turbine technology. This innovative design incorporates an additional rotor that rotates in unison with the main rotor along the same axis. Without the supplementary rotor, the turbine's configuration is analogous to that of a horizontal-axis wind turbine (HAWT) with the main rotor functioning independently. The primary objective of this study is to undertake a comparative analysis of the effectiveness of mechanical energy generation, as measured by torque, between the CRWT and HAWT designs. The configuration of the wind turbine is situated within a wind tunnel, characterized by a rectangular cross-section. The testing of wind turbines has been conducted at wind velocity of 2 m/s, 3 m/s, and 4.5 m/s. The total mechanical power measured was 0.14 W, 0.21 W, and 0.28 W at wind velocity of 2 m/s, 3 m/s, and 4.5 m/s, respectively. The final results of the study have analyzed the effectiveness of power enhancement through power coefficients.
