The remainder of human activity in the form of solids, whether deliberately disposed of or not into the marine environment is called marine debris. This study aims to determine the weight, composition and density of marine debris in Purus, Padang City. Sampling was carried out from February to April 2021. Determination of the location by purposive sampling using line transect sampling method. Waste is separated based on macro and meso sizes and then the weight and amount of each type of waste is calculated. From the research results found 9 thypes of waste, namely types of plastic waste, plastic foam, cloth, glass and ceramics, metal, paper and cardboard, rubber and wood and another materials. There were 9805 pieces of waste with a total weight of 27170.74 gr, consisting of 21554.7 gr of macro waste and 5616.4 gr of meso waste. Based on the weight of waste, the most dominant types found were cloth (9311.6 gr) for macro waste and 5616.04 gr for meso waste. The highest density is found in the type of wood with WD02 code as much as 50.92 pieces/m2 for macro waste and WD06 as many as 226.8 pieces/m2 for meso waste.

Marine debris is all forms of solid objects that are disposed of intentionally or unintentionally into the marine environment. Research on the type, composition, amount, and density of marine debris that washed up on Air Manis Beach and Pasir Jambak Beach has never been done. The purpose of this study was to determine the source, amount, type and density of marine debris found at Air Manis Beach and Pasir Jambak Beach, Padang City. The research was conducted from March to July 2022. The method used to collect waste was using the line transect method, the location determination was carried out intentionally according to research needs (purposive sampling). All waste obtained during the study was grouped by type, amount and size. Based on the research, it is known that the garbage stranded on the two beaches comes from the river, the activities of residents around the location, fishing activities and visiting tourists. It was found that there were 36232.24 grams of waste consisting of 36195.4 grams of macro waste and 36.84 grams of meso waste. Macro waste with the highest percentage was found in plastic waste (86.84%), and for meso-sized waste was found in metallic waste (72.27%). The density of marine debris at Air Sweet Beach and Pasir Jambak Beach is 23.36 pieces/m2 for macro waste and 4.2 pieces/m2 for meso waste.

From several studies it was revealed that there are still many people who use formalin and borax in food because these ingredients are easy to obtain. Nagari Sasak is one of the areas in the Sasak Ranah Pasisia District, West Pasaman Regency, located on the coast where most of its residents produce salted fish for their livelihood. The procedure used by fishermen in this area when processing salted fish is still traditional. This study aims to analyze the presence of formalin and borax in salted fish processed by conventional fishermen in Nagari Sasak, Sasak Ranah Pasisia district, West Pasaman regency. The samples used in this study included seven types of dried salted fish obtained from three processors in KanagarianSasak. For more details, the types of salted fish tested consist of three kinds of anchovy (Stolephorus sp.), giant trevally (Caranx sp.), yellow jack (Caranx sp.), barracuda (Sphyraena jello), and tobi (Sardinella fimbriata). The research sample was obtained by purposive sampling way. In addition, the method used in this research is the descriptive method, while the data analysis is gained through qualitative descriptive methods. The test parameters of this study included formalin and borax qualitative tests and organoleptic tests of dried salted fish. The results showed that five out of seven salty fish samples, as much as 71.43%, were detected to contain formalin.

The presence of microplastics is dangerous for fish and human health. The small size of microplastics (0.0001-0.5cm) makes it easier for microplastics to enter and accumulate in the bodies of living creatures. This research aims to analyze the shape, color and abundance of microplastics in fish landed at Pasir Jambak Beach, Padang City. The research was carried out in April - September 2023. Microplastic observations were carried out at the LLDIKTI X Laboratory using an Olympus CX21 microscope. The results of the research showed that the three types of fish landed, namely Mackerel fish (Rastrelliger neglectus), Lemuru fish (Sardinella lemuru) and Tongkol fish (Euthynnus affinis), were contaminated by microplastics. The total abundance of microplastics in three fish meats was 130 particles/g. The highest percentage of microplastic abundance was found in fiber microplastics with a percentage of 77% and the dominant color of microplastics was black.
