Abstract

Indonesia merupakan negara yang kaya akan sumber daya alam, salah satunya kekayaan alam flora. Hal ini dipengaruhi karena Indonesia beriklim tropis. Salah satu tanaman yang banyak tumbuh di wilayah Indonesia adalah pohon pepaya. Pada tahun 2021, jumlah pepaya di Indonesia mencapai 1.168.266 ton dan mengalami kenaikan sebesar 14,94% dari tahun sebelumnya. Salah satu upaya untuk meningkatkan manfaat daun pepaya yaitu dengan mengekstraksi daun pepaya tersebut untuk digunakan sebagai inhibitor korosi. Penelitian ini bertujuan untuk mengekstraksi daun pepaya dengan memvariasikan jenis pelarut yang digunakan yaitu metanol dan etanol serta daya microwave yang digunakan sebesar 150, 300, dan 450 watt. Metode ekstraksi yang digunakan adalah Microwave Assisted Extraction (MAE) dengan waktu ekstraksi selama 15 menit. Analisis yang dilakukan adalah analisis kadar air, rendemen, dan uji fitokimia untuk mengetahui kandungan senyawa dalam ekstrak daun pepaya secara kualitatif. Hasil pengujian kadar air sebelum dan setelah pengeringan didapatkan bahwa kadar air awal daun pepaya sebesar 70,87% dan mengalami penurunan menjadi 6,92%. Sementara itu, rendemen ekstrak daun pepaya dengan pelarut metanol lebih besar dibandingkan rendemen dengan pelarut etanol, yang mana rendemen tertinggi dengan pelarut etanol dan metanol berturut-turut sebesar 72,07% dan 72,41%. Berdasarkan uji fitokimia dihasilkan bahwa ekstrak daun pepaya mengandung senyawa alkaloid.

Abstract

Corrosion is a problem that occurs in many industries and causes large losses. The use of corrosion inhibitors is one way to reduce or inhibit corrosion. Cigarette butt waste extract can be utilized as an organic corrosion inhibitor. This study aims to determine the yield of cigarette butt waste extract, the content of cigarette butt waste extract produced using the MAE method qualitatively, determine the optimum conditions for the extraction process with the MAE method based on variations in microwave power of 150 and 300 watts and calculate the efficiency of corrosion inhibitors and the effect of compounds contained in cigarette butt waste extract in 3.56% NaCl environment. The optimum MAE condition was 150 watts and 15 minutes, with an extract yield of 54.38%. Based on the GC-MS test, it is known that cigarette butts waste extract contains alkaloid, terpenoid, and phenol compounds as corrosion inhibitor compounds. Based on corrosion inhibitor testing, the addition of cigarette butt waste extract corrosion inhibitors can suppress or reduce the corrosion rate that occurs on metals with an inhibitor efficiency of 79.19% in non-aerated conditions and 71.53% in aeration with an inhibitor concentration of 1000 ppm in a 3.56% NaCl environment.

Abstract

Cigarette butts are one of the wastes found in many places, and their presence can damage the environment. One way to reduce the amount of cigarette butts waste is to process them into corrosion inhibitors. This study aims to extract tobacco from cigarette butts using 96% ethanol solvent by varying the extraction time for 5, 10, 15, and 20 minutes, and microwave power of 150 watts and 300 watts, and calculating the efficiency of corrosion inhibitors in acidic environments. The extraction method used was Microwave Assisted Extraction (MAE). From the extraction process, it is known that the optimum extraction power of 150 watts in 15 minutes produces the highest yield of 64.52%. Based on phytochemical and GC-MS tests, it is known that cigarette butt extract contains antioxidant compounds in the form of alkaloids, pyranones, and terpenoids as corrosion inhibitor compounds. Based on corrosion testing, it is proven that the addition of cigarette butt waste extract corrosion inhibitors can suppress or reduce the corrosion rate that occurs on metals with the most excellent efficiency of 82.26% with an extract concentration of 2000 ppm. And the SEM-EDX test results concluded that the corrosion inhibitor from cigarette butts waste extract can withstand the formation of rust on the metal.
