This research aims to know the influence of understanding Accounting Information Systems, Leadership Style, Employees Motivation, and Work Discipline in Employees Performance at KC BRI Sidoarjo. The instrument is in the form of google forms to get research data. This research data collection is validity test and reliability test. The hypothesis is that there is an the influence of understanding accounting information systems, leadership style, employees motivation, and work discipline in employees performance. The analytical tool used to test the hypothesis is SPSS version 18. The test results based on the validity test show that all questions on Google Forms are declared valid. While the test results based on the reliability test of all variables, the value of cronbach's alpha > 0,6 means that it is declared reliable and for the results of the Hypothesis Test in the form of T-Statistic and R-Square, it states that there is an influence between understanding accounting information systems, leadership style, employees motivation, and work discipline in employees performance. This is shown from the results of tcount for the variable understanding of the accounting information system (X1) of 2.113, the variable of leadership style (X2) of 2.101, the variable of employees motivation (X3) of 2.114, and the variable of work discipline (X4) of 2.189.

High Order Thinking

The research was conducted to determine the characteristics and forms of matter; similarly determine the validity, reliability, as well as the students' response to the measurement results HOT reasoning about TIMSS models to measure student HOT developed. The method used is the research development. Products in the form of multiple choice questions as well as the reasons of the students' answers. Student responses obtained from the questionnaire responses the students after using such a matter. Based on the criteria of due diligence in a very good product. Characteristic of reasoning about TIMSS models which contain components reasoning refers to the TIMSS. About the validity of the overall test results show that the question is valid and feasible to use to measure student HOT. Reliability test results indicate that the matter is reliable and can be used well. Student response after use problems in the excellent category, obtained a percentage of 82.66%. HOT measurement results in the category of students is still low, at SMPN 8 Semarang amounted to 51.54%, SMP Kartika III-2 Semarang amounted to 31.16%, and the MTs NU amounted to 47.68% Ungaran. Problem reasoning models that have been developed decent TIMSS used to measure student HOT.

Power Operation

The reliability of optical sources is strongly dependent on the degradation and device characteristics are critically dependent on temperature. The degradation behaviours and reliability test results for the laser diode device (Sony-DL3148-025) will be presented .These devices are usually highly reliable. The degradation behaviour was exhibited in several aging tests, and device lifetimes were then estimated. The temperature dependence of 0.63?m lasers was studied. An aging test with constant light power operation of 5mW was carried out at 10, 25, 50 and 70°C for 100hours. Lifetimes of the optical sources have greatly improved, and these optical sources can be applied to various types of transmission systems. Within this degradation range, the device life for system application is estimated to be more than 100 h at 70 ºC at a constant power of 5mW.

Gas Market

The downhole oil and gas market is continually pushing for higher reliability at higher temperatures. Satisfying this need requires continuous improvement, driven by failure analysis of both internal testing and field returns. This paper discusses recent lessons learned from on-going tests. Results of unpowered circuit assembly tests are reviewed. Also, a detailed analysis of separate powered life testing is presented. The internal testing results are further discussed in the context of field return data.

Two lead free solders were developed for die attach application. The bismuth based solder has a melt temperature of 271C and thermal conductivity of 18W/mK. The zinc based solder has a melt temperature of 337C and thermal conductivity of 85W/mK. Both solders have acceptable wetting on bare copper and nickel plated copper substrate, could be processed using modified high lead solder process condition and survived 260C board level reflow simulation. This paper discusses the solder material properties, and presents the die attach process and reliability test results in a manufacturing environment.

Cumulative Fatigue Damage

A new method for correlation test was presented to study the reliability of a heavy duty vehicle, and the method can combine the real customer usage with the enhancement test on proving ground, and avoid the test blindness. Aiming at the data that were tested on the typical pavements of the customer and enhancement roads of proving ground, the rain-flow counting method was used to obtain the load distribution matrixes , according to the correlation equation, the cumulative fatigue damage and loading spectrums of the 90% customer and proving ground were optimized and calculated. Through the correlation analysis, the pavements enhancement coefficient and the reliability test specifications were obtained. The test results indicate that the new specifications can predict the potential failures of the load carrying structures quickly, shorten the test cycles.
