Abstract

This study aims to find out and to analyze the Current Ratio, Capital Structure, and Corporate Size partially affect the Financial Performance of Mining Companies listed on the Indonesian Stock Exchange (BEI) in the period 2014-2016. The sample used is 120 financial statements of mining companies listed in BEI. The method used in sampling is purposive sampling. Data is collected by downloading, recording, researching, and copying information relating to the issues discussed in the study. Data analysis using descriptive statistics, classical assumption test, and multiple linear regression analysis, t-test, and coefficient of determination (R2). The results of this study indicate that current ratio and the size of the company does not affect on financial performance of mining companies on BEI in the 2014-2016, while the capital structure has a significant effect on the financial performance of mining companies on the company’s financial performance.

Abstract

As a security for land traffic in the area of railroad crossing in general, a crossing is required. Increasingly busy traffic, the number of railroad crossings today, to prevent accidents either due to human error or the lack of compliance by motorists with traffic regulations, a controller that can regulate the flow of traffic at the railroad crossing is needed. The research objective was to design an automatic railroad crossing controlled by Arduino with the C language programming command. This research will make a prototype of the Automatic Crossing Gate using the halls effect A3144 sensor as an on and off switch by detecting the presence of a magnetic field (Lorentz force) on a passing train. The stages of the research method are: Provide the necessary components, namely Arduino, bread board circuit board, buzzer, A3144 sensor, LED, servo motor as a latch dynamo, Make programming tests on the Arduino for each buzzer, LED, A3144 sensor, servo motor as a latch dynamo, Assembling the overall components on the bread board as a model, Make overall programming on the Arduino from the circuit, and test the circuit on the bread model board,  Assemble the prototype clearly with a mini train accompanied by a rail with a loop in the form of a track, Test the maximum distance, the effective distance between the A3144 half effect sensor and the train.
