Abstract

PERUMDA Tirta Muaro Unit Teluk Singkawang in the dimension of assurance is still not good. As evidenced by the low scope of service in this unit. Marked by the number of customers in 2020 as many as 2035 people. While the population of Sumay Subdistrict in 2020 as many as 21,398 people (Tebo Regency in Numbers, 2021). This means that the service coverage is 9.5%. This has not met the government's target of drinking water services of 75% for rural areas (Permen PU No. 13, 2013).This type of research includes explorative descriptive research using qualitative statistical research techniques. This research method uses survey method with customer population of PERUMDA Tirta Muaro Unit Teluk Singkawang. Sampling techniques using slovin formula. The analysis technique uses multiple linear regression analysis, with F test and t test using SPSS software. The results of the study that the level of customer satisfaction based on respondents' responses to 5 (five) dimensions of service quality received a score of 3.54 in the category of satisfied.

Abstract

The Batanghari River as a source of raw water for Perumda Tirta Mayang, Jambi City, in the last few decades has experienced a decline in water quality due to land conversion and human activities. A lot of rubbish is found in rivers dominated by plastic waste which will fragment into microplastics with a size of <5 mm. Microplastics will affect the process of processing raw water into clean water at Perumda. This research aims to identify and assess the polymer risk index and microplastic pollution index in the Batanghari River in the Sijenjang Intake area. The tool used is Planktonet mesh 150 with a diameter of 20 cm. The research results showed that the sizes of microplastics found ranged from 2-5 mm, 1-2 mm, 0.5-1 mm, 0.1-0.5 mm and <0.1 mm. The microplastic colors were transparent, blue, white, black, clear, green, and brown. The types of microplastics found were fibers, filaments, fragments, and pellets. The abundance of microplastics ranges from 100 – 150 particles/liter. The polymer risk index (PRI) value is between 25.6 and 32.74 in the medium category, while the microplastic pollution index (PLI) value is between 44.72 and 54.77 in the very high category.
