Abstract

Research on the activity of eugenol derived compounds as antimicrobials using the qualitative structure-activity relationship (QSAR) model has been conducted. Molecular structure modeling was executed computationally using the ChemDraw Ultra 12.0 program package. Geometry optimization was performed using AM1 semi-empirical method to stabilize structure with the least energy level. Calculations of hydrophobic, electronic, and steric descriptors were done using Gaussian-09 and Marvin Sketch 64 softwares. Statistical calculations was conducted through multiple linear regression method using the IBM SPSS 25 program. Statistical analysis was carried out based on the statistical requirements of several equation models so that the best equation model was obtained. The analysis with the QSAR equation model obtained that the model 1 equation presented the best results.

Abstract

Marine pollution, originating from land-based sources and intentional dumping at sea, is a significant hazard to marine life and health. Plastic pollution, which constitutes about 85% of marine debris, causes severe damage to marine ecosystems and species, causing disruptions in marine activities and deteriorating seawater quality. This research aims to see the distribution of marine debris in the coastal waters of Ternate city. The method used in this research is purposive sampling technique through observation to obtain the composition of marine debris, the rate of increase of marine debris with 3 criteria, namely the presence of river mouths, community activities such as ecotourism activities and piles of garbage produced by fishermen. The data obtained was then analyzed by visually observing and recording. The result of this study is the discovery of organic and inorganic waste. The percentage density of organic waste is 13% while inorganic waste is 87%. This shows that inorganic waste is generated the most. Inorganic waste in the form of plastic, cloth, glass, steroform and aluminum is produced by human activities visiting the coast. The organic waste found is wood and fruit peels.
