As a group, Aulia Ervazia, Fedro Rudy Hasiando, and Mohamad Fajar are interning in PUPR for retaining wall project in Bekasi. The Bekasi River flood control project 6 was carried out because the Bekasi River in the area could no longer accommodate the flowing water for the next few years so that if it rained, the river could not accommodate the discharge flowing from upstream. The retaining wall was replaced for 3 KM from STA 0 to STA 2+970.

“I was placed in the water resources division of the structural division. The structure used in this project is a retaining wall with different types according to the type of soil at each point. The structural design for this project was previously planned and we only revised and redesigned it because the previous design was long behind and the new project was to be carried out in 2021. In this division I was trusted to use the Plaxis application to check the value of the safety factor and sliding force. In addition, my friends and I like to do field inspections to check the work in the field.”

“I checked the drainage in the field, in order to find out the coordinates of each drainage, which from the results of these coordinate points can be designed catchment area in the package 6 project. Several times with changes in data and design from the owner, namely PUPR, I help Mrs. Naila as an assistant expert in calculating data inventory and creating a new catchment area, then taking coordinate data with the vendor using the RTK (Real Time Kinematic) tool which functions as a satellite navigation technique used to improve the accuracy of the position data obtained. obtained from a satellite-based positioning system. GPS RTK uses measurement of the phase of the signal carrier wave in addition to the information content of the signal and relies on a single reference station or virtual station that is interpolated to provide real-time correction. Then after the measurement, enter the data into excel inventory data. Then after I finished working on the rainfall data in several cities so that I entered the data into excel which I will later enter into the hydrology report for enrichment this time.”

I am Fedro Rudy Hasiando as a student who is doing an internship at the Bekasi River Flood Control Package 6 project. I have quite a variety of activities, my activities during the internship were quite diverse, including surveying river locations, assisting administration, directly monitoring project activities in the field and other matters. other. But in the end, I was placed in one division, namely the Quality Control division, which is in charge of inspecting the materials to be used in the project, such as checking the screw and the quality of the concrete.
In the examination of the screw iron, an examination of the diameter and length of the screw is carried out. For the quality of the quality of the concrete itself, a slump test is usually carried out just before casting, which in this project the slump test value is +-18, during the inspection of the quality of the concrete, tests are also conducted on the compressive strength of the concrete and the weight of the concrete on each concrete sample, at intervals of 7 days. , 14 days, and 28 days. I also occasionally participate in the Quantity division where I attend MC 0 meetings, MC 0 itself is used to calculate the volume of work which will later be used for scheduling and calculating BOQ (Bill of Quantity).
