Red brick is a building material widely used in Indonesia as a non-structural separator wall of a building. Soil is the main material in the production of red bricks. The soil used for the main material of red brick is sandy clay soil. The advantage of red brick is that it is resistant to hot weather or fire because it has undergone the combustion process. However, new innovations are necessary for the red brick manufacturing process due to the reduced soil. The innovation carried out in this study was adding the main material with fly ash and rice husk ash. The purpose of this study was to obtain red brick mixture fly ash and rice husks with increased compressive strength than normal red bricks. The research method used is an experimental method with the addition of fly ash and rice husk ash by 4%, 8%, and 12% of the soil weight. The results obtained from this study are red bricks with fly ash and rice husk ash produced the highest value in the fly ash mixture of 12% (in sample D2) content of 75.07 Kgf / cm² so as to improve the quality of conventional red bricks.

Authors:Mahdika Putra Nanda Pages: 118 - 124 Abstract: Abstract. Brick is a building material widely used as a construction material for walls and fences, one of which uses Pozzolan brick. Pozzolan brick is made from Trass, lime, or cement. A local material that can be used as an additional fiber in the mixture of Pozzolan brick making is fibers, because it has been proven that the addition of fibers in concrete can improve its physical and mechanical properties, in addition, the fibers also have a hard rotten nature because there is no decomposer that can decompose them. Thus, it is necessary to investigate the addition of fibers as fiber in Pozzolan bricks. The experimental method was used in this study. The purpose of this study is to find out whether Pozzolan bricks with the addition of a mixture of fibers have better compressive strength and to find out whether they meet the requirements to become bricks according to SNI 15-2094-2000 and PUBI-1982. From the results of research and analysis that has been done regarding the addition of fiber fibers (Arenga pinnata) as a fiber to the compressive strength of pozzolan bricks, it is found that the compressive strength of pozzolan is 4.99 Mpa with a porosity value of 3.24%, thus pozzolan bricks can provide economic value for the wider community. Based on the compressive strength and porosity, pozzolan bricks also meet the requirements to become bricks according to SNI 15-2094-2000 and PUBI-1982 in grade III.

Water flowing in the river causes a scouring event that occurs at the bed channel. The existence of scouring will increase along with changes in the geometry of the river and obstacles such as the weir which are followed by local scouring around the weir. Local scouring often occurs downstream end of weir sill which weakens its construction. Scouring measurement was conducted to monitor the pattern of scouring that occurs. By using Surfer software, the scouring visualization through the Data Grid and 3D Surface can be seen. In this research, scour monitoring in the laboratory using open channels (flume) and MDO weir with fine aggregate material as the basis of the channel. The retrieval of scouring data was performed after installing fine aggregate and three times variations of flow discharge, then the data were processed using Surfer. The first flow used water level +3.50 with the material carried at 3.77%. The second flow used water level +4.50 with the material carried at 11.16%. The third flow used water level +5.70 with the material carried at 25.46%. So with the continuous method, the total material carried at 36.27% is equivalent to 12575.77 cm3.

Authors:Nurina Vidya Ayuningtyas, Istiana Adianti Pages: 150 - 157 Abstract: Abstract. The building sector is one of the world's largest energy consumers. This problem is further exacerbated by our dependence on non-renewable energy sources. More than 90% of the world's energy comes from fossil energy including oil, natural gas and coal whose availability in nature continues to decrease because they cannot be renewed. Green design is a reaction to the global environmental crisis. Green design which also leads to eco design, or design for environment is the art of designing physical objects and the surrounding environment to balance sustainable principles with economic, social, and ecological aspects. As a construction actor, you are required to be able to produce a building design that does not require too much energy consumption and also of course considers the comfort of the occupants in it. In an effort to develop the campus, Universitas Gadjah Mada seeks to make the UGM campus a Green Campus.

Authors:Egi Gustian, Roi Milyardi, Cindrawaty Lesmana Pages: 158 - 168 Abstract: Abstract. Everywhere in the world, especially as the fourth industrial revolution begins, technological advancements are being discussed. This technological advancement also affects the building industry, one example being the use of Building Information Modeling (BIM) technology. All technologies, particularly BIM, will advance and redevelop throughout this Covid-19 epidemic. BIM has benefits and barriers to implementation that increase with its development and sophistication, particularly for contractors. Therefore, it's important to research the advantages of using BIM as well as the barriers for contractors. The purpose of this study is to analyze the benefits and inhibiting factors in the implementation of BIM in building construction for contractor. This research was conducted by using literature from previous studies to find out what statements are the benefits and barrier factors in the implementation of BIM 4D for contractors with top and middle qualifications. Then the statement was compiled into a questionnaire and distributed to respondents via online platform. In addition to obtaining the mean value for each research variable, the questionnaire survey responses were processed utilizing validity and reliability tests. The findings of this study show that the benefits of BIM implementation for top contractors include better and more appealing building design or modeling, more accurate documentation, as well as better and more attractive building design or modeling for middle contractors. The lack of training and education in BIM itself is the main obstacle to its implementation for these top contractors, while the cost of licensing BIM software or apps is fairly high for midrange contractors.
