Abstract

The rapid development of industrialization and urbanization in the world impact increased water pollution. Human activities, such as dam constructions, excessive water consumption, severance of river flows, compaction of riverbanks, and excessive use of riverbed vegetation, disrupt river flow and alter the original hydrological cycle. In response to these conditions, this study aims to analyze water quality and river quality status to set up a watershed environmental management strategy in Aceh Province as a case study. River water quality was analyzed descriptively by comparing the results of laboratory tests with parameters, namely TSS, pH, BOD, COD, DO, total phosphate, nitrate, and fecal coli. These parameters were then transformed into the environmental index (Water Quality Index and Pollution Index). It was found that Water Quality Index (WQI) results are shown from 50 to 70. WQI with the Good category is at Kr. Weh which is in the Central Aceh city. The medium-less type is found in 10 watersheds. The water quality with the category of Less is found at 3 points, namely Kr. Aceh, Cr. Doy, and Cr. Daroy. The quality of the river water in the Aceh region, from upstream to downstream, has decreased in quality with a lightly polluted status based on the Minister of Environment and Forestry of the Republic of Indonesia No. 27 of 2021 for class II.

Abstract

The performance and characterization of biodegradable plastic from tapioca starch was studied. Modified the chitosan was one of the ingredients for produce the biodegradable plastics. The produced biodegradable polastic were thin sheet plastic, elastic and transparent. The biodegradable plastic performance had tensile strength between 2,26-3.73 Mpa, elongation ranges from 17.24 to 76.76%, and water absorption ranges from 30.81-268.9%. In antioxidant analyze, apples are wrapped in plastic and had significant mechanical properties changes on 8th day.Morphology scanning result showed that in the chitosan-polyNIPAM there were no cavities may caused high hydrophilicity in the biodegradable plastic.
