Abstrak :
This book is designed to provide engineers with a better understanding of heat treatment and its effects on gear quality and performance, especially as these considerations are critical to ensuring that the gears perform satisfactorily under anticipated service conditions. Increased demand for gears to transmit more power through smaller, lighter, quieter, and more reliable packages that must operate over a wide range of service conditions has made the design and manufacture of gears much more complex. Gears manufactured from certain steels are found to meet these demands, and become especially effective when heat treated and finish machined for high geometric accuracy. However, distortion of the gear after heat treatment offers the engineer a challenging opportunity not only in ensuring a high quality product but also in controlling manufacturing costs. Heat treat distortion of gears is discussed in detail for the major heat treat process, and a case history of each successful gear heat treat process is included. Contents: Introduction to Gear Heat Treatment Properties of Iron Heat Treatment of Gears Through-Hardening Process Carburizing and Hardening Nitriding Modern Nitriding Processes Carbonitriding Induction Hardening Selection of Heat Treat Process for Optimum Gear Design.

Penelitian ini bertujuan untuk menganalisis pengaruh pengaruh Bank Size, Gearing Ratio, Non Performing Loan, Asset Management, Operating Efficiency, dan Capital aAdequacy Ratio terhadap profitabilitas (ROA dan ROE) Bank Umum. Penelitian ini menggunakan metode regresi data panel pada 30 perusahaan Bank Umum yang terdaftar di Bursa Efek Indonesia (BEI) tahun 2008-2015. Hasil penelitian ini variabel Bank Size, Gearing Ratio, Asset Management, dan Capital Adequacy Ratio tidak signifikan terhadap profitabilitas (ROA) sedangkan Non Performing Loan dan Operating Efficiency signifikan terhadap profitabilitas (ROA). Variabel Gearing Ratio, Operating Efficiency dan Asset Management signifikan terhadap profitabilitas (ROE) sedangkan Non Performing Loan, Capital Adequacy, dan Bank Size tidak signifikan terhadap profitabilitas (ROE).

The purpose of this study was analyze the effect of the influence of Bank Size, Gearing Ratio, Non Performing Loan, Asset Management, Operating Efficiency, and Capital Adequacy Ratio to profitability (ROA and ROE). This study uses regression method data panel on 30 conventional banks, listed on Indonesia Stock Exchange (BEI) in 2008-2015. The result of this research is Bank Size, Gearing Ratio, Asset Management, and Capital Adequacy Ratio are insignificant to profitability (ROA), whereas Non Performing Loan and Operating Efficiency significantly to profitability (ROA). Variable Gearing Ratio, Operating Efficiency and Asset Management are significantly to profitability (ROE), whereas Non Performing Loan, Capital Adequacy Ratio, and Bank Size are insignificant to profitability (ROE).
