Buildings have various building systems. One of the building systems is a lift. Like other building components, lift can be damaged. Lift defect occur in various places. Lift defect can be caused by vibration in the lift elements, the age of the lift that has exceeded what it should have been, vandalism, constraints in the budget, even preventive maintenance, corrective maintenance, and operations. Research on preventive maintenance, corrective maintenance, and operations that cause lift defect has been widely studied in residential buildings. Research on educational buildings in this case universities on this subject is still rarely found. Comprehensive preventive maintenance, corrective maintenance, and operational studies have been carried out in Spain and Malaysia, but each of these studies was carried out by the same researcher. Research from accredited journals in Indonesia on this matter has also not been found. On the other hand, incidents about this have been found in many newspapers. Meanwhile, the discussion on preventive maintenance discusses limited to investment and lift maintenance activities in one of the journals in Indonesia. Therefore, this study aims to find the effect of management and preventive maintenance, corrective maintenance, and operational activities on lift defect. The research also aims to provide recommendations for lift preventive maintenance, corrective maintenance, and operational management and activities. This research uses a case study approach as well as qualitative and quantitative methods. Data was collected through literature studies, interviews, surveys, and questionnaires. Research is limited to campus buildings in this case Labtek ITB and only to Labtek that are 20 years old. Interviews were conducted with the Directorate of Facilities and Infrastructure and Labtek IX-A, IX-B, and IX-C in the initial survey. Collecting data in the form of questionnaires distributed online using the judgemental sampling method to the Head of Sub-department or the party responsible for Labtek maintenance including lifts. Data analysis is done by looking at patterns and differences, comparing, and seeing cause-and-effect relationships. The results showed that door jamming was the most common type of defect experienced by lifts. This defect is mostly caused by the long life of the components. This confirms previous research. The long life of the components makes the lift must be replaced. Lifts that have exceeded the maximum age limit can endanger users. Routine maintenance makes lifts at ITB rarely cause accidents and routine maintenance can maintain the condition of lifts at ITB even though they are at their maximum age or exceed their maximum age. It can be concluded that routine maintenance can be carried out for lifts that are already at their maximum age to be able to maintain their condition before updating. Meanwhile, if lift upgrade (modernization) will be done, the campus manager can choose to modernize part or all of the lift. On the other hand, the door is the component that suffers the most damage. This confirms previous research and the initial research of this study. Other research results are the frequent occurrence of defect to doors and ropes caused by preventive maintenance, frequent occurences of defect to batteries, doors, ropes, buttons, and light switches caused by corrective maintenance, and frequent occurences of defect to almost all components caused by operations. Preventive maintenance, corrective maintenance, and operations all cause damage (defect) to the door. Labtek IX-A and XI lifts often experience battery defect. On the other hand, Labtek IX-C and XI lifts often experience lift ropes defect. Labtek VI, VIII, and IX-C lifts often experience the lift car defect. Meanwhile, all Labtek often experience damage to lift doors except Labtek IX-C. Lift buttons and light switches defect is often experienced in Labtek X Lifts. Alarm defect are often experienced by Labtek IX-A Lifts. Labtek VII lifts are the only lifts that often experience door defect caused by preventive maintenance, corrective maintenance, and operations. Among all preventive maintenance activities, cleaning is the most dominant cause of lifts defect. Door components defect as a result of this can be handled by making cleaning guidelines. Meanwhile, among all corrective maintenance activities, repairs that have not been carried out are the dominant cause of lifts defect. The door is the component that has experienced the most repairs that have not been carried out. Repairs that have not been carried out can be handled from the campus building management by simplifying the bureaucracy. On the other hand, it is advisable to resolve the problem of the length of replacement of spare parts in the bureaucracy due to the budget. Among all operational activities, the use of lifts that are not good by building users is the major cause of lifts defect. The component that suffered the defect because of this was the door in the form of a student holding the lift door. Things that can be done are providing a prohibition marker for holding the lift door, an efficient scheduling system (efficient lift scheduling system), and an occupancy model.
