Abstract

Liquid waste from dyeing is the main source of pollution in small industrial areas such as Griya Kain Tuan Kentang, Palembang City, which is famous for its woven and jumputan fabric production. Liquid waste from these activities has the potential to pollute the surrounding environment. Therefore, it is important to evaluate its quality to support ecosystem sustainability and public health. This study aims to analyse the quality of wastewater using physical parameters (temperature, TDS, TSS and brightness), chemical parameters (pH, Cd, Pb, Fe, Cu), and biological (Coliform and Escherichia coli contamination). The type of research used is quantitative research with experimental methods and laboratory tests. Samples from three locations were analysed in the integrated laboratory of UIN Raden Fatah Palembang and directly analysed on site for physical parameters (temperature, TDS and brightness), biological parameters were analysed using the MPN (Most Probable Number) method, and chemical parameters for heavy metals using AAS (Atomic Absorption Spectroscopy). The results of this study provide an overview of the quality of wastewater at Griya Kain Tuan Kentang which has not met the wastewater quality standards according to the Regulation of the Minister of Environment in 2016 for the brightness and TDS parameters at locations 1 and 2 have met the wastewater quality standards, at location 3 the brightness parameters have not met the wastewater quality standards.

Abstract

Polymers are essential components in various aspects of human life, particularly in the production of different types of materials and products. One of the primary applications of polymers is in the manufacturing of adhesives or glues used to bond various substrates. PG 6802 ALV adhesive, for example, is widely used in the ceramic box industry. This research was conducted to test the characteristics of PG 6802 ALV adhesive in several production batches at PT. XYZ, namely batches 0119LSA001, 0219LSA002, and 0219LSA004. One of the measured parameters was the viscosity of the adhesive using a Brookfield viscometer with a spindle 0.4 at a speed of 10 rpm. The measurement results Brookfield viscometer with a spindle 0.4 at a speed of 10 rpm. The measurement results showed that the viscosity of PG 6802 ALV adhesive ranged between 10500 cps, 10400 cps, and 11600 cps. Additionally, measurements of the adhesive's solid content were obtained in the range of 60.40% to 60.95%. The density of PG 6802 ALV adhesive ranged from 1.0528 to 1.0705 g/ml, while the pH was in the range of 5. In conclusion, this research provides an overview of the physical and chemical characteristics of PG 6802 ALV adhesive in several production batches. The measurement results of viscosity, solid content, density, and pH provide important information for a better understanding of the properties of this adhesive. This knowledge can be utilized for the development of improved products and the enhancement of the production process in the ceramic box industry and other adhesive applications.
