In order to make informed decisions on routine maintenance of bridges of expressways, the hierarchical regression analysis method was used to quantify factors influencing routine maintenance cost. Two calculation models for routine maintenance cost based on linear regression and time-series analysis were proposed. The results indicate that the logarithm of the historical routine maintenance cost is the dependent variable and the bridge age is the independent variable. The linear regression analysis was used to obtain a cost prediction model for routine maintenance of a beam bridge, which was combined with the quantity and price, and verified by a physical engineering example. In order to cope with the cost changes and future demands brought about by the emergence of new maintenance technologies, the time-series analysis method was used to obtain a model to predict the engineering quantities for the routine maintenance of a bridge based on standardized minor repair engineering quantities. Taking into account the actual cost of the minor repair project as well as the time-series analysis’ sample size demands, the annual engineering quantity was randomly decomposed into four quarterly data quantities, and the time-series analysis result was verified by physical engineering. These results can improve the calculation accuracy of the routine maintenance costs of reinforced concrete beam bridges. Furthermore, it can have a certain application value for improving the cost measurement module of bridge maintenance management systems.

Purpose The purpose of this paper is to identify and assess the significance of various factors affecting maintenance costs of public school facilities. Design/methodology/approach Detailed literature review resulted in identifying 54 factors that were categorized under nine groups. This was followed by a questionnaire survey completed by 60 experienced professionals. The relative importance index was used to determine the in-group ranking, as well as the overall ranking of these factors. Findings The study established that the five most significant factors affecting the maintenance cost of public school facilities were “not providing operations and maintenance manuals to maintenance group” in the “construction phase” category, “ignoring maintainability studies in design” in the “design phase” category, “specification of low-quality materials” in the “design phase” category, “selection criteria of contractors” in the “regulations and contracting” category, and “lack of quality control during work execution” in the “construction phase” category. Originality/value The present research represents the first research covering the maintenance cost of public school facilities in Saudi Arabia. The study also presents the unique landscape of facility maintenance in the Saudi Arabian context. The outcome of this research has the potential to significantly cut down unnecessary costs rooted in expensive maintenance of public school facilities, enhancing the quality of these facilities. The findings also underscore the necessity of collaboration and coordination of the various key disciplines toward the realization of cost-effective school facilities.

Burning Hours is the one of  policy in scheduling aircraft maintenance. With the burning hours the operator could performed aircraft maintenance before the due time. Burning Hours is indeed beneficial for flight operators to maintain the stability of the safety of the aircraft operation. Using the quantitative analysis method with the sample data’s from two aircraft, found that the burning hours affects to Burning Hours Cost loss for every aircraft meintenance activity. The value of Burning Hours Cost Loss and Potential Lost per Day needs to be considered by operators in scheduling maintenance activities, because it is possible that Burning Hours cannot be avoided in aircraft operation. Based on the data processing,  the  value of burning hours cost lost is not more than limit of potential lost per day.  However it should also be considered if burning hours applied continuously will increase maintenance cost. Therefore, between maintenance planning department and the operation department should keep good coordination to minimize the burning hours cost loss. Keywords: Planning, Maintenance, Burning Hours

Pneumatic Cylinders

Pneumatic Cylinders are one of major mechanical components which are widely used in various industries such as automobile production line and semiconductor inspection device due to its low contamination and low maintenance cost. Most of existing studies on pneumatic cylinders have focused on their performance improvement such as operating sliding friction measurement, contact stress minimization, appropriate dynamic response, and etc. This research carried out life tests of pneumatic cylinders and the concerned failure mechanism was the degradation of pneumatic polyurethane seal since leakage caused by seal degradation occurs very frequently. The considered operating parameter was environmental temperature. To assess operating temperature as an acceleration parameter, the lifetime of a pneumatic cylinder was tested at high temperature and the degradation mechanism and characteristics of sealing surface were analyzed by statistical Weibull analysis method as well as by surface analysis using pyrolysis gas chromatography. Ultimately this research will help the life prediction of other pneumatic reciprocating machines.

The dapodic system application is a system application that makes it easy for school users or operators to input all types of data related to school, such as active teacher data, non-active teacher data, active student data, non-active student data, report cards, schedules, and school facilities and infrastructure. The purpose of this research is to analyze how kindergarten school management is implemented with the dapodic application. The first method used is the data collection method, data analysis method, and system application implementation. The end result of this research is a perfect and maximum dapodic application that makes it easier for users to do their work.

Infrastructure Maintenance

The aim of this study is to discover and obtain information about the upkeep of educational facilities and infrastructure at Vocational High School 2 Cikarang Barat. The analysis method used is descriptive qualitative. The study took place at Vocational High School 2 Cikarang Barat from July 2020 to December 2020. The school principal, deputy headmaster in charge of facilities and infrastructure, maintenance support staff, and students of Vocational High School 2 Cikarang Barat served as research informants. Interviews, observation, and reporting studies are all used to collect data. After that, the data is analyzed by reducing it, presenting it, and drawing conclusions. The triangulation of sources, techniques, and hypotheses is a validity technique. The study's findings indicate that: (1) Vocational High School 2 Cikarang Barat maintenance preparation starts with a work meeting, and then maintenance is divided into two categories: normal and routine maintenance. A one-year budget is generated after deciding maintenance tasks based on their categories. Following that, representatives from the facilities and infrastructure sector specifically select the structure of facility and infrastructure maintenance, as well as their respective job desks in each division, which are known to the school principal. The final move is to socialize students at school. (2) School maintenance processes and techniques begin with frequent and routine maintenance. Routine maintenance includes the upkeep of classrooms, teacher's offices, and special rooms such as libraries, computer laboratories, and science labs. The school also performs routine maintenance on air conditioners, printers, and photocopiers, as well as computer program upgrades. (3) Obstacles faced by schools in preparing facility and infrastructure repairs, including, among other problems, things that arise unexpectedly and need urgent repair at the facility. The lack of knowledge of users of school facilities and infrastructure, partners with outsiders who are often less sensitive, and cultural differences among individuals in the use of facilities and infrastructure are among the process and technological obstacles encountered.
