Abstract

Industri transportasi di Indonesia memiliki peran krusial dalam pembangunan negara, serta dalam memenuhi kebutuhan mobilitas dan pengiriman barang ke berbagai lokasi. Stabilitas kinerja keuangan merupakan faktor krusial yang bisa menarik minat investor guna menginvestasikan modal di sebuah perusahaan. Maka penting bagi perusahaan guna mempertahankan kestabilan kinerja keuangannya. Penelitian ini akan membahas mengenai penilaian kinerja keuangan perusahaan melalui analisis rasio keuangan, yaitu rasio likuiditas dan solvabilitas. Metode yang digunakan ialah pendekatan kuantitatif deskriptif dengan data sekunder yang didapat dari laporan keuangan perusahaan. Teknik pengumpulan data dilakukan melalui dokumentasi dan studi pustaka. Sebanyak 12 perusahaan dipilih sebagai sampel menggunakan teknik purposive sampling. Analisis data dilakukan dengan regresi linear berganda menggunakan SPSS V. 24. Hasil penelitian menunjukkan bahwa rasio likuiditas berpengaruh signifikan terhadap kinerja keuangan perusahaan, sedangkan rasio solvabilitas tidak memberikan pengaruh yang signifikan. Namun secara simultan, kedua rasio tersebut memiliki kontribusi terhadap kinerja keuangan perusahaan dalam sektor yang diteliti.

Abstract

In modern times like this, many wheelchairs have been developed with various controls, ranging from manual ones, namely by being pushed by other people or using their hands to turn the wheel, to automatic ones, such as electric wheelchairs that use joysticks and Electromyography control. The control of the electromyography signal utilizes muscles that can still be used to move the wheelchair, in this case, using the hand muscles. The use of a Bluetooth wireless system in sending electromyography signals aims to facilitate the use of a wheelchair without interference from the many connected cables so that users are more flexible in placing the electromyography sensor on the user's hand muscles. By placing the electromyography sensor on the user's arm, the electromyography sensor detects a contraction or relaxation, which is indicated by the LED flame. The output value of the sensor will be compared with a predetermined limit value. When the value is greater than the limit value, it will produce a logic low; when the value is less than the limit value, it will build a logic high. The Arduino microcontroller will calculate every low logic. The results of these calculations will be processed into serial data. The serial data will be sent to the HC-05 enslaved person via the HC-05 master wirelessly. The motor driver will execute the data so that it produces motion forward, backward, turn right, turn left and stop. It is hoped that this tool can help individuals with limited movement so that they do not have difficulty in mobility.
