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.

Abstract

Sedimentation is a crucial factor when it comes to river problems. Sediment can cause silting of the river so that its capacity be reduced and can cause overflow of water to the surface. Every year, Districts of Nanga Mahap at Sekadau Regency always experiences flooding and the problem is still happening up until now. One of the causes of the occurrence of flooding in Nanga Mahap District is the overflow of the Mahap River. This study aims to determine the characteristics and rates of bottom sediment transport rate in the downstream of the Mahap River. Sediment collection was carried out on 8 segments of the estuary. In the study, laboratory tests were carried out regarding specific gravity and grain size of sediment particles refers to the texture classification by USDA (U.S. Department of Agriculture) and freight rate calculations Basic Sediment with Duboys Method. Based on characteristic analysis Mahap River sediments obtained the average D50 sediment grain diameter value from all research points that is equal to 1.63 mm, the results of testing the specific gravity the average obtained is 2.754 gr/cm3 so that it can be classified in the form of coarse grains with a type of sand sediment. The largest base sediment transport rate of bed load occurred at point 2 of 8.816 tons/day and the smallest was at point 7, which is 0.154 tons/day. From the calculation, result shows that if the velocity of falling particles is greater than the velocity of the flow of river water, therefor the sediment particles will settle.
