Abstract

Input of nutrients into the waters from various human activities (residential and industry) has the potential to cause changes in the physical, chemical and biological conditions of the waters. The study aims to determine the relationship of concentrations of nitrate, phosphate and silicate with the abundance of diatoms in the Meral waters. The method used is the survey method, the determination of the location of sampling is done by purposive sampling, data analysis (multiple regression). Based in the results of laboratory analysis nitrate concentrations ranged from 0,033 – 0,051mg/l, the phosphate concentration ranged from 0,076 – 0,086 mg/l, and silicate concentration ranged from 0,043 – 0,052 mg/l. The abundance of diatoms in Tanjung Tiram waters ranged from 90,3 – 208,3 ind/l. The results of statistical analysis of the relationship of nitrate, phosphate and silicate with the abundance of diatoms are expressed in terms of equation y = 58,460 + 904,562Nitrate – 251,562phosphate + 1573,489Silicate. This statement explains the concentration of nitrate, silicate positive (+) to the abundance of diatoms and phosphate related negative (-) to the abundance of diatoms. This condition shows that the nutrient concentration in these waters is relatively high so that it affects the abundance of diatoms.

Abstract

Coastal and marine areas have the potential for anthropogenic pollution. Solid waste, especially plastic, is a pollutant that contributes greatly to polluting coastal areas. Plastic will degrade into small sizes known as microplastics. The purpose of this study was to determine the content of microplastics in the Padang and Pariaman Coastal Waters, West Sumatra. This research was conducted in November 2021 in the seawaters of Padang Wisata Beach (Air Manis Beach and Muaro Lasak Beach) and Pariaman Beach (Kata Beach and Gandoriah Beach) of West Sumatra Province. Based on the results of the study, four types of microplastics were found, namely fiber, film, fragments, and granules. The type of fragment is the dominant type found, followed by the type of film, fiber and granules. Microplastic abundance at Air Manis Beach ranged from 616.67-2196.97 particles/m3, Muaro Lasak Beach 916.67-2396.67 particles/m3, Kata Beach 320.00-1190.00 particles/m3, and Gandoriah Beach 550, 00-1363.33 particles/m3. In general, at Padang Beach and Pariaman Beach by type, microplastic fragments were the most common type found with a percentage of 53%. The type of film is the second most common type (32%), followed by the type of fiber (11%) and the type of grain (4%). Microplastics were distributed in seawater at Padang Beach and Pariaman Beach with different abundances.

Abstract

One of the microalgae that are widely used in the industrial world is Spirulina platensis which has high nutritional content of protein, fatty acids, vitamins and antioxidants. In its growth, this microalgae requires media and the addition of macronutrients nitrate and phosphate which greatly affect the growth and productivity of S. platensis biomass. This study aims to determine the effect of nitrate and phosphate concentrations on S. platensis biomass on an indoor scale and to determine the optimal nitrate and phosphate concentrations to achieve maximum biomass. This research was conducted in August 2020 as an experimental method, with culturing S. platensis with the addition of different concentrations of nitrate and phosphate. The design used in this study was a Completely Randomized Design consisting of 5 treatments that are 0 ppm, 10 ppm, 20 ppm, 30 ppm, and 40 ppm, each treatment with 3 repetitions. The source of nitrate and phosphate used is NPK. Water quality parameters during culture with temperatures ranging from 29-30oC, salinity 25-26 ppt, and pH 8. The optimal concentrations of nitrate and phosphate to achieve the maximum biomass is in treatment C (30 ppm) with a total of biomass 0,43 g. Whereas in treatment D (40 ppm) the biomass did not show a significant increase because the dose was too high with a total of biomass only 0,299 g
