Abstract

Oil is one of the petroleum derivatives that cause environmental pollution. Oil used in the automotive industry such as workshops is often not managed properly, so that it becomes waste that can cause soil pollution and water pollution. One way that can be used to overcome this pollution is by bioremediation by utilizing Escherichia coli and Staphylococus aureus bacteria as bioremediation agents. The purpose of this study was to determine the ability of E.coli and S.aureus bacteria in degrading oil. The method used was experimental method. The results obtained show that E.coli bacteria have the ability to degrade waste oil by bioaccumulation which is characterized by the presence of oil clots in the center of the media. While S. aureus bacteria have the ability to degrade waste oil by biodegradation which is characterized by the decomposition and change in the shape of oil oil into white granules.

Abstract

Penelitian ini bertujuan untuk menganalisis faktor-faktor yang mempengaruhi angka Kemiskinan di Indonesia, Malaysia, dan Thailand pada tahun 2000 2020. Penelitian ini menggunakan regresi data panel untuk melihat pengaruh variabel bebas terhadap variabel terikat. Adapun variabel terikat pada penelitian ini adalah kemiskinan, serta variabel bebas yaitu angka melek huruf (AMH), jumlah penduduk, pengangguran, angka harapan hidup (AHH), dan produk domestic bruto (PDB). Penelitian ini mendapatkan hasil bahwa adanya pengruh positif dan signifikan antara angka melek huruf (AMH) dan produk domestic bruto (PDB) terhadap kemiskinan, serta variabel jumlah penduduk, pengangguran,dan Angka Harapan Hidup memiliki pengaruh negative dan signifikan terhadap kemiskinan.Kata kunci: Kemiskinan, Angka Melek Huruf, jumlah penduduk, pengangguran, Angka Harapan Hidup (AHH), dan Produk Domestik Bruto (PDB)
