Abstract

Abstrak: Penelitian ini bertujuan untuk mengetahui pengaruh Likuiditas, Leverage, dan Profitabilitas terhadap nilai perusahaan pada perusahaan sub sektor food and beverage yang terdaftar di BEI periode tahun 2015-2018. Likuiditas diproksikan dengan Current Ratio (CR), Leverage diproksikan dengan Debt to Equity Ratio (DER), dan Profitabilitas diproksikan dengan Return On Asset (ROA). Pengambilan sampel menggunakan teknik purposive sampling, sehingga didapatkan sampel sebanyak 12 sampel perusahaan food and beverages yang terdaftar di Bursa Efek Indonesia. Metode penelitian yang digunakan dalam penelitian ini adalah analisis regresi berganda. Hasil penelitian ini menunjukkan Leverage dan profitabilitas berpengaruh positif dan signifikan terhadap nilai perusahaan, sedangkan likuiditas berpengaruh negative dan tidak signifikan terhadap nilai perusahaan.Kata kunci: Likuiditas, Leverage, Profitabilitas, Nilai Perusahaan, Current Ratio, Debt to Equity Ratio, Return On Asset

Abstract

Nowadays, halting greenhouse gasses (GHG) emission is the world's major concern to mitigate global climate change. In oil palm cultivated tropical peatland, GHG emission is primarily constituted of CO2 flux emitted from aerobic heterotrophic respiration (Rh), the natural degradation process of organic material in an oxidative environment. By coupling descriptive and predictive statistical approaches, this study attempt to gain an in-depth understanding of the effects of zeolite rates and incubation time on CO2 emission that came from aerobic Rh in peat, as well as their decomposition process. This study found that zeolite amelioration up to 30% of the peat at field capacity and starting from the first month of observation (month-1) significantly restricted peat Rh, denoted by a reduced amount of observed CO2 flux (0.021 and 0.019-0.012 mg m-2 sec-1, respectively). Both factors and several soil variables exhibited some non-linear relationships with Rh at different magnitudes and importance, showing the limitation of the traditional linear-based approach to interpreting their complex interrelationships, as well as predicting CO2 flux. This study highlights the vital role of a polynomial (GAM) and artificial intelligence (Cubist and GBM) -based pedotransfer models in improving our understanding regarding the dynamic of the peat decomposition process as affected by zeolite amendment.
