Abstract

Economic growth in a country can be reflected by the number of construction projects. To achieve robust economic growth, effective human resource management is required to enhance productivity. One aspect that affects work productivity is the labor force. This research aims to analyze the factors and tasks that influence labor productivity in Concrete Bearing Replacement Projects. Given the many factors or criteria to consider, the Fuzzy Analytical Hierarchy Process (Fuzzy AHP) method is used for identification. The Fuzzy AHP method assists in evaluating various criteria and determining the relative weights of each factor to make informed decisions. To simplify the analysis, 4 criteria and 12 sub-criteria are used. Based on the analysis, the factor with the greatest impact on labor productivity is the work area (K2-1) with a weight of 0.1327, while the factor with the lowest weight is the accuracy of material delivery to the location (A2) with a weight of 0.0442. The tasks that relatively impact labor productivity include loading and unloading concrete bearings (A3) with a weight of 0.0029, replacing concrete bearings with a weight value of 0.0026, and the lowest impact tasks are dismantling gongsol and revising curves, with a weight value of 0.0022.

Abstract

Lampung University plays an active role in implementing and campaigning for green development, so a study is needed that can be used as part of the implementation of the Green Building concept. The selection of the location of Building B FEB is based on the condition of the building which is still new so that it is expected to be easier to improve. The research method includes a survey of building conditions, interviews, and assessment of six green building criteria based on the Green Building Council Indonesia (GBCI) version 1. These criteria include Appropriate Site Development (ASD), which emphasizes the selection of a location and sustainable management of the surrounding environment; Energy Efficiency and Conservation (EEC), which focuses on reducing energy consumption and implementing energy-saving technologies; Water Conservation (WAC), which highlights the efficiency of water use and management; Material Resource and Cycle (MRC), which refers to the use of environmentally friendly and easily recycled materials; Indoor Health and Comfort (IHC), which includes air quality, lighting, acoustics, and occupant thermal comfort; and Building Environmental Management (BEM), which focuses on sustainable building operations, including waste management and maintenance. The results of the survey and field analysis show that the total Green Building assessment score of Building B FEB Unila is 37, which is in the Bronze category. Efforts that can be made to increase this value include the commitment of the entire academic community in environmental campaigns, reducing the use of private motor vehicles, and water conservation in building management.
