Abstract

In the operation of the electric power system, there are often short circuit disturbances, both permanent and temporary, the use of the connection can cause deviations in the variable variables of the electric power system, such as voltage, frequency.The load growth on the 150 kV Teluk Naga Tangerang Baru Sindang Jaya (Tangerang) Banten network system is increasing day by day. The cause is the current development of development. The growth of the load increases the possibility that the number of loads will exceed the existing generation capacity in the future. With the growth of the load that continues to increase, the possibility of blackouts increases if at any time there is a problem with one of the plants. Therefore, this is a concern by PLN on plants that are not equipped with equipment to increase transient stability. For this reason, the Banten 3 Lontar PLTU needs a Power System Stabilizer on the generator. Before activating this feature, it is necessary to conduct a transient stability analysis to determine the system's response to the network it is supplied with. Observation of the changes that occur will show how much the Power System Stabilizer has an effect on increasing transient stability. In the final result, it can be seen that the transient stability increases after the use of the Power System Stabilizer

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh likuiditas (Current Ratio), profitabilitas (Return On Assets), dan leverage (Debt to Equity Ratio) terhadap tax avoidance dengan ukuran perusahaan sebagai variabel moderasi pada perusahaan manufaktur sub sektor makanan dan minuman yang terdaftar di Bursa Efek Indonesia pada tahun 2018 – 2023. Teknik analisis data yang digunakan dalam penelitian ini adalah analisis moderasi dengan pendekatan Moderated Regression Analysis atau uji interaksi dengan alat analisis menggunakan SPSS versi 26. Metode pemilihan sampel yang digunakan adalah purposive sampling. Total pengamatan yang diperoleh pada penelitian ini adalah sebanyak 115 pengamatan yang terdiri dari 24 perusahaan. Hasil pengujian penelitian ini menunjukkan bahwa secara parsial likuiditas (Current Ratio) dan ukuran perusahaan berpengaruh positif dan signifikan terhadap tax avoidance, sedangkan profitabilitas (Return On Assets) dan leverage (Debt to Equity Ratio) tidak berpengaruh namun signifikan terhadap tax avoidance. Secara simultan, likuiditas (Current Ratio), profitabilitas (Return On Assets), leverage (Debt to Equity Ratio), dan ukuran perusahaan berpengaruh positif dan signifikan terhadap tax avoidance. Hasil dari uji analisis moderasi menunjukkan bahwa ukuran perusahaan tidak mampu memoderasi pengaruh likuiditas (Current Ratio), profitabilitas (Return On Assets), dan leverage (Debt to Equity Ratio) terhadap tax avoidance.
