Abstract
The aim of building maintenance is to preserve the function, structure, and aesthetics of the building in accordance with the initial conditions. An ineffective building maintenance management leads to increased cost, reduced building reliability, and failure to achieve the green building mission. One problem highlighted is that building management are still using call-center system with no database to store building damage data. Therefore landscape and housekeeping components are damaged below the allowable standard and become no longer functional. The purpose of this study is to improve the maintenance performance on landscape and housekeeping components of government green buildings. The case study was the Ministry of Public Works and People’s Housing Republic of Indonesia. The research methods used are literature reviews, surveys, case studies, and expert judgement for validating content and construct. This study uses a Work Breakdown Structure (WBS) in managing data dynamically using Building Information Modelling (BIM), integrated with web-based information systems. The result is that using BIM-based website leads to a more effective and efficient maintenance, thus improving the maintenance performance especially comfort on landscape and housekeeping components. The most significant variable according to the coefficients model are infiltration well, trash bin, groundcover, carpet floor, and visualisation.

Published: May 2020

Abstract
Comfort is one indicator in the performance of building maintenance. This performance can be achieved by carrying out maintenance work on the building architecture components. The maintenance of government green buildings in Indonesia has not been done in an optimum manner due to constraints in maintenance work to government green buildings such as non-digitized data, poorly documented data, substandard maintenance work, and poor or slow identification of damages. Impacts resulted from the poorly maintained building are the increasing operational cost and ineffective maintenance work done to the building. The aim of this study is to increase the comfort of maintenance performance of the architectural component of government green building, especially the wall work package. The case study taken is the Ministry of Public Works and Public Housing Building which is considered as a representation of government green building in Indonesia. The method used are literature research, case study, and survey. The result of this research is the information system development using Building Information Modelling (BIM) integrated into building maintenance systems such as Work Breakdown Structure (WBS), SOP, and building maintenance guidelines for architectural components.

Abstract
Land is one of the construction materials available in the field that has diverse properties. Clay is a bad type of soil if it has poor soil properties such as high plasticity, low shear strength, high swelling, and large shrinkage potential. Soil stabilization is an effort to improve the quality of the soil by using certain materials to increase soil strength. Soil improvement by using mixture materials are mostly done to stabilize the soil. The mixing material used is Lapindo mud. A number of soil improvement techniques are offered to overcome problems in soft soil. The selection of soil improvement techniques is generally based on the formation of soil geology, soil characteristics, and costs. The stabilization used is emulsion asphalt which is locked of 8% and Lapindo mud variation of 3%, 6%, 9% and 12%. The results of physical and mechanical properties on soil material with stabilization of Lapindo mud and emulsion asphalt were obtained that the specific gravity increased by about 68%, with the density value (ωopt) of 16% and the dry weight content (γd) of 6%. In the compressive strength testing, the more Lapindo mud mixture, the less compressive strength (qu) value.

Abstract
Soft clay is soil that need microscopic to sub microscopic size originating from the chemical weathering of rock compilers. Clay soil is very hard in a dry state and is plastic at moderate water content. At higher water contents the clay soil is sticky (cohesive) and very soft. Soil stabilization is an effort to improve the quality of the soil by using certain materials to increase soil strength. Soil stabilization is the process of mixing soil with certain materials to improve the technical properties of the soil and is an attempt to change or improve the technical properties of the soil to meet certain technical requirements of the soil carrying capacity. This research is an experimental study to determine the carrying capacity of clay soil stability using volcanic ash deposits and tailings instead of cement. The research variables are volcanic ash deposits which is locked of 8% and tailings with the variation of 4%, 5%, 6% and ripening for 3 days, 7 days and 14 days. The benefits of this experimental study are expected to get the carrying capacity of the soil from stabilized soil greater than the carrying capacity of the original soil by the unconfined compression test (UCS).

Authors: Subagdja A , Sofyan A , Rusmanto A 
Published: May 2020

Abstract
One of the causes of cracked reinforced concrete in the seawater environment is direct contact between concrete and sea water. This is because cement as a binding material in concrete does not have a good ability to withstand corrosive conditions in seawater. Ground Granulated Blast Furnace Slag (GGBFS) which in this case is B3 waste can be a solution. From several studies conducted previously, the behaviour of GGBFS concrete against sulfate and chloride attacks showed positive results but relatively little is known about GGBFS material produced by steel mills in Indonesia. Therefore, an experimental study of the characteristics of compressive strength and permeability test using GGBFS (0%, 20%, 30%, 40%, 50%, and 60%) with 72 concrete cylinders in 28 and 40 days. Microstructure of GGBFS concrete test using Scanning Electron Microscopy (SEM) was also studied. The result of this experimental study is GGBFS microstructure, compressive strength and concrete permeability for better effectiveness concrete in seawater, so that it can become one of the alternative solutions for infrastructure development especially for seawater infrastructure in Indonesia.
Moveable bridge inspection in Ancam Port North Kalimantan, Indonesia
Authors: Sumargo S , Rusmanto A 
Published: May 2020

Abstract
The Ancam Port is equipped with a moveable bridge to anticipate tides. The Moveable Bridge structure is a steel frame bridge with a length of 35,740 meters. This vertical free movement is accommodated by the pontoon but cannot deform in a horizontal plane in the direction of the bridge extending, causing damage to the connection between the pier and the moveable bridge. Under the pontoon there are indications of piles emerging from the riverbed and recurring collisions occur due to tides. This causes leakage so that water enters and causes an imbalance from the pontoon and a collapse of the Moveable Bridge occurs. The movable bridge analysis method is carried out using SAP 2000 software. Based on the analysis of the collapse the moveable bridge is able to withstand the planned load on the condition that the pontoon has to function properly. The solution to re-enable the moveable bridge is to use a geofoam-type styrofoam pontoon wrapped in steel plates. This research is expected to be a solution to the problem of movable bridges in Indonesia.

Abstract
Building maintenance is an activity of maintaining the reliability of buildings, infrastructure and facilities to have the proper functions and are not damaged quickly. The main goal is to manage a building and its grounds, as well as customize needs for the facility and achieve the reliability requirements of building (comfort, safety, health and convenience). The problem is that the current condition of building maintenance is generally still conventional. As a result, the building maintenance process tends to be slow, often neglected, and can often result in insignificant additional costs. For example, the condition of a tempered glass was dirty and dusty conditions, then this will disrupt the lighting in the room, so that electricity will increase while the functional value of green buildings decreases. This certainly contradicts to the principle of green building that carries Energy Efficiency & Conservation/EEC, which is caused by non-maximization of one green building’s components especiall in architecture components. The purpose of this research is to improve the performance of maintenace work to green buildings in state’s buildings for architecture components. The research methods used are literature study, data analysis and case studies of information systems development. Minister of Public work regulation 24/2008 are used as a Guidelines for Building Maintenance which are then integrated into the Information System-WEB. By developing an information system for maintenance, the performance of Architecture Components in green building will be achieved 4 points from building requirements and reduce the possibilities damage in future especially for plafond and tempered glass damage. The results of this studies is a web-shaped information system that is useful for state agencies and others in carrying out the work of maintaining a green buildings, especially in the architecture component.

Published: May 2020

Abstract
The micro-cracks that commonly occur in concrete structures are a potential source of crack propagation which leads to the possibility of catastrophic failure. Concrete cracks that occur propagating mainly along the interface zone that significantly conditioned by aggregate characteristics. Aggregate characteristics as concrete fillers have a significant role as a strain energy release medium known as fracture energy. This research is using an experimental investigation about the fracture characteristics of concrete using different gradations with a maximum diameter of 25 mm and 20 mm. The experiment includes a compressive strength test and a fracture parameter test. Three-point bend test was selected based on RILEM recommendations to calculate fracture parameters. The result has shown that the aggregate gradations used in concrete mixtures should take into account the effect on compressive strength and total fracture energy. Uniform gradations with smaller maximum sizes have high compressive strength but low fracture energy.

Published: May 2020

Abstract
Instead of reducing the unemployment rate, Center Berau of Statistic (BPS) 2018 data shows that Vocational High School (SMK) graduates contribute high to the number of unemployed in Indonesia. The high number of unemployed is partly due to the low technical skills and transferable skills of students. Transferable skills are considered very important to strengthen and complement technical skills, amid the disruption of the world of work in the industrial era 4.0. In order to strengthen transferable skills, innovative learning methods are needed, which involve active student participation. The One Group Pretest-Posttest experimental research was conducted to find out the increase in transferable skills of SMK X students in the Building Design and Information Design Study Program (DPIB), through the implementation of project-based learning methods. The results of the gain index analysis, hypothesis testing, and observation results indicate that the application of project-based learning methods can improve the transferable skills of vocational students.
