Abstract

Since the construction of building F, Dr. University. Soetomo Surabaya has not experienced any changes either in terms of form or other points of view. Based on observations of the current condition of the building, there is still not enough attention and the age of the building already requires care, maintenance and repair of damage. Building quality greatly influences building user satisfaction because good building quality can make users feel comfortable in the building. The aim of this research is to analyze damaged items, analyze the level of user satisfaction and analyze poor building conditions. The method used in this research is a quantitative method where data collection was carried out by distributing a questionnaire survey via Google Form to 135 respondents consisting of lecturers at the Faculty of Engineering and students using building F, Dr. University. Soetomo Surabaya, apart from distributing questionnaires, this research was carried out by direct observation. This research uses the customer satisfaction index method which aims to determine the level of satisfaction of building users and uses the help of Smart-PLS software to help process data generated from questionnaires by testing its validity and reliability. The results of this research showed several damages, including damage to columns, beams, floor plates, walls, finishing, glass and door frames, floors and ceilings. The damage in this study refers to the classification of building damage according to (PUPR, 2021) where overall damage to walls is categorized as very light damage, damage to columns is categorized as moderate damage, damage to beams is categorized as heavy damage, damage to floor slabs is categorized as heavy damage. , damage to the floor is categorized as light damage, damage to the ceiling is categorized as moderate damage, and for finishing it is categorized as heavy damage due to complete finishing damage. The research results on the level of user satisfaction with building conditions using the customer satisfaction index (CSI) method were 55.41%, which means building users are quite satisfied with the current condition of the building. Apart from that, the results of the condition of the building, according to the respondent's point of view, which were not good were damage to the color of the wall paint, condition of the ceiling, door and window accessories, doors and windows, door and window frames, walls. Keywords: Building Damage, User Satisfaction, Customer Satisfaction Index, Smart-PLS

Abstract

ITS Surabaya Student Dormitory Building uses PDAM clean water services and is also equipped with a fire extinguishing installation whose distribution network system uses clean water. As students' needs increase, their need for clean water will also increase. And because of this, this building often experiences problems distributing clean water during peak usage hours due to simultaneous use, there is a decrease in the flow of each unit of piping equipment due to uneven installation of the clean water distribution system. Therefore, the distribution system in pipes requires special handling which often experiences problems in terms of quantity, pressure and continuity of water. The aim of this research is to analyze the magnitude of energy loss in the plumbing pipe network in the ITS Surabaya Dormitory Building, and also to analyze the causes of closed pipes experiencing energy loss. At which point the energy loss is highest, so is the remaining energy at the last pipeline node. The method used in this research is a quantitative method by analyzing the condition of the existing pipe network in clean water installations and fire extinguishing installations in terms of pipe dimensions, pipe length and reservoir elevation which will then be carried out by running tests with the program to find out how much The large energy losses that occur in plumbing pipe networks are assisted by a simulation program using Epanet 2.2. From the results of this research, there are several conclusions that the results of the analysis of the Clean Water pipe network of the ITS Surabaya Student Dormitory Building for clean water installations have the highest velocity (Velocity) of 0.2 m/s in pipe 15 on the 1st Floor, and the sprinkler pipe has a velocity (Velocity). ). ) the highest is 0.08 m/s on pipe 01 Floor 2. There are still many pipes whose speed is less than 0.1 m/s, which means the pipe speed in the network does not meet the design criteria. And for the pressure of the clean water pipe network and sprinklers at all node points with a value of ≥0.5 bar (according to planning standards). Based on the results of running unit headloss, the clean water pipe network and sprinklers have a value of <10 m/Km (according to planning standards) and no pipes experience negative pressure or pressure drop.
