Abstract

Garbage is a major problem experienced on a global scale, both from household and industrial waste. This research was conducted at Pantai Cermin, Pantai Cermin Kanan Village, Pantai Cermin District, Serdang Bedagai Regency. It was carried out on 6-12 November 2021 with the aim of knowing the type, characteristics, weight, total density, and rate of increase in weight of inorganic waste. The method used is purposive sampling by installing a plot of 10 m x 10 m with a distance of each transect of 5 m. Data collection was carried out by observation with macro size and recorded directly. The results of the research show that the waste obtained is plastic, glass, rubber, clothing, metal / metal and the most dominant is plastic waste. The density of the number of pieces and the largest weight density in plastic waste are 0.31 items/m2 and 2.93 gr/m2. The highest rate of weight gain was on Sundays (r>0).

Abstract

This study aims to examine the toxicity of phenoxy acid herbicides on vannamei shrimp mortality, by conducting preliminary tests, persistence tests, mortality tests, and water quality. The research design used the regression method and probit analysis with 6 treatments and 3 replications, namely A herbicide concentration of 0 ml/L, B herbicide concentration DMA-6, 0.025 ml/L water, C herbicide concentration DMA-6, 0.005 ml/L water, D DMA-6 herbicide concentration, 0.075 ml/L water, E DMA-6 herbicide concentration, 0.1 ml/L water and F DMA-6 herbicide concentration, 0.125 ml/L water. Pesticides do not affect temperature changes, dissolved oxygen (DO), Salinity, and pH. Clinical symptoms due to Pesticide exposure to vanamei shrimp are irregular movements, shells peeling off, and swimming close to aeration until they die. The LC50 value in the herbicide toxicity test was 0.124 mg/l at 24 hours, 0.099 mg/l at 48 hours, 0.073 mg/l at 72 hours, and 0.026 mg/l at 96 hours.
