Abstract

The Kapuas River Basin (DAS) has great benefits for the community, especially for clean water needs. The community's need for water starts from the need for drinking water to the need for sanitation. But along the flow of the Kapuas River has experienced pollution. To prevent and improve river water quality, it is necessary to test the water quality in the Kapuas River area and find out the causes of pollution in the research location. This research was conducted in Sintang City as the upstream watershed and Pontianak City as the downstream watershed. Determination of water quality status is carried out using the STORET method. The results obtained, the water of the Kapuas River in the city of Pontianak is classified as heavily polluted. Meanwhile, the Kapuas River water in Sintang City is classified as moderately-severely polluted. The source of the pollutant comes from domestic waste. Efforts to prevent and improve water quality can be carried out by educating the local community regarding water quality and building a Communal WWTP to treat this waste.

Abstract

The high rainfall in Pontianak provides a great opportunity to utilize rainwater as a source of clean water in the area. This study aims to analyze the potential for utilizing rainwater in the Panca Bhakti University environment from the aspects of reliability and volume of water that can be accommodated. The study was conducted through a quantitative method by measuring the roof area, and collecting rainfall data from secondary data, as well as simulating the calculation of the volume of water that can be accommodated from the roof of the campus building. The results of the study showed that the roof area of ​​the building in the Panca Bhakti University area is 1,508.99 m2. From the roof area, the calculation results show that the potential volume of rainwater that can be accommodated is 282,181.13 liters / month or 11,757 liters / day. The total need for clean water use in the Panca Bhakti University environment is 69,926 liters / day. The percentage of rainwater capacity from the total daily clean water use requirement is 16.814%. From the results of this calculation, we can conclude that in terms of reliability, rainwater has not been able to meet the clean water needs in the Panca Bhaktit University Area as a whole. However, if we integrate it with the use of PDAM water, rainwater has great potential to meet the campus's water needs, especially in reducing the cost of PDAM water usage bills, especially in daily activities that do not require drinking quality water, as well as contributing to groundwater conservation and reducing environmental impacts.

Abstract

In the proper category, buildings must stand upright, sturdy and strong for a long period of time and no settlement occurs. Panca Bhakti University (UPB) is currently building campus facilities and infrastructure to meet the growing number of students, one of which is the rectorate building. Before the rectorate building is put into operation, an initial investigation is needed to find out whether or not settlement has occurred in the building structure. Settlement is a decrease in subgrade elevation caused by a layer of soil that is loaded on it, causing the soil beneath to experience an increase in stress. The implementation of the research is by making observations and measuring settlement behavior with a waterpass. The purpose of this investigation is to identify and monitor settlement behavior and determine settlement values ​​that occur in the structure of the Panca Bhakti University rectorate building. The results showed that the highest settlement value occurred at observation points T2-LT.4 and T6-LT.4 with a value of 5 mm. At the observation points T6-LT.1, T1-LT.4, and T3-LT.4 the height difference was 3 mm. While the observation points T1-LT.1, T2-LT.1, T3-LT.1, T4-LT.1, T5-LT.1, T4-LT.4, and T5-LT.4 with a value of 0 , it can be said that there is no difference in height. The average height difference value of all observation points is 1.58 mm. Settlement data is needed so that the risk of structural damage to buildings can be identified early. With this research data, it can be used as a justification for the reliability of the building as well as reference data for monitoring the maintenance of the Panca Bhakti University rectorate building in the future.
