Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh likuiditas, solvabilitas, rentabilitas terhadap nilai perusahaan dimediasi oleh profitabilitas pada perusahaan LQ45 di BEI periode 2018-2020. Penelitian ini termasuk dalam penelitian kuantitatif dengan menggunakan regresi linier berganda. Populasi pada penelitian ini adalah perusahaanbLQ45 yang terdaftar pada BEIbperiode 2018-2020. Pemilihan sample menggunakan teknik purposive sample sejumlah 57 perusahaan. Data dianalisis menggunakan bantuan aplikasi SPSS. Berdasarkan hasil penelitian yang dilakukan diperoleh kesimpulan bahwa bahwa likuiditas, solvabilitas, dan rentabilitas berpengaruh signifikan terhadap profitabilitas. Likuiditasidan rentabilitas juga berpengaruh signifikan terhadap nilai perusahaan. Namun Solvabilitas menunjukkan pengaruh yang tidak signifikan. Profitabilitas tidak mampu memediasi hubungan antara likuiditas, solvabilitas, dan rentabilitas terhadap nilai perusahaan Pada Perusahaan LQ45 di BEI periode 2018-2020.

Abstract

This research aims to design and develop a mobile gas-leak detection robot using the MQ-2 sensor, capable of operating in both automatic and manual modes to inspect areas with potential leakage. The system addresses the limitations of static detectors, which can only monitor a single point and are unable to cover long pipeline segments. The robot is built using an Arduino Nano as the main controller, an HC-05 Bluetooth module for remote control via an Android application, and an L298N motor driver to regulate DC motor movement. Testing was conducted by placing the robot inside a acrylic pipe simulating a leaking pipeline, allowing gas concentration readings to be collected from multiple positions. Results indicate that the system successfully detects increased gas concentration as the robot approaches the leak source. The manual mode enables users to direct the robot toward specific locations, while the automatic mode provides stable motion along the test path. Bluetooth integration performs reliably within a 5–10 meter control range. Overall, the robot demonstrates effective performance as a mobile inspection platform, offering greater flexibility, responsiveness, and information richness compared to static gas-leak detection systems.
