Abstract

Onchidiid slug (Onchidium typhae) is a nudibranch that coastal communities in West Kalimantan have widely used as wounds. The study aims to characterize the West Kalimantan water O. typhae as antibacterial and antifungal. The study of O. typhae was carried out in several stages: preparation and optimization, extraction by Quinn method, characterization and identification of bioactive compounds, and antibacterial and antifungal assay using the microdilution method. The result of the proximate test showed that O. typhae powder contains high protein, namely 67.68%. Phytochemical screening results from methanol, ethyl acetate, and chloroform extracts contain alkaloids and amino acids. Methanol, chloroform, and ethyl acetate extract 1% of O. typhae showed inhibitory activity against Staphylococcus aureus, Escherichia coli, and Candida albicans. The most significant inhibition value was indicated by chloroform extract 1%, where the inhibition value against S. aureus, E. coli, and C. albicans was 82±0.01%; 85.8±0.01%; 85±0.01%, respectively. From these results, O. typhae powder can be developed as a wound medicine through its antibacterial and antifungal activity.

Abstract

Siput Onchidid (Onchidium typhae) merupakan spesies dalam kelas gastropoda yang dapat ditemukan di daerah pesisir pulau Buton dan juga Madura dan Kalimantan Barat.. Siput onchidid diketahui memiliki kandungan metabolit sekunder berupa steroid yang dapat berpotensi sebagai antioksdian. Penelitian ini membahas tentang uji antioksidan di dalam siput onchidid dengan metode DPPH (1,1- diphenil-2-pikrilhirazil) dengan menggunakan pelarut methanol dan pengujian skrining senyawa metabolik ekstrak dengan uji fitokimia pada ekstrak yang meliputi uji steroid, alkaloid, dan steroid. Hasil pengujian didapat bahwa ekstrak metanol siput onchidid memiliki terdapat senyawa metabolik sekunder dari golongan alkaloid dan steroid yang ditandai dengan reaksi positif. Hasil uji antioksidan dengan metode DPPH dengan senyawa pembanding vitamin C. Penelitian menunjukkan besar aktivitas antioksidan ekstrak metanol siput onchidid yang dinyatakan dengan nilai IC50 sebesar 92,045 yang dikategorikan antioksidan kategori kuat.
