Abstract

The use of wood as a construction material is common throughout Indonesia. Based on this, wood material is easy to obtain and wood material itself can make buildings look more attractive. Wood as a source of materials for both construction and non-construction makes the price of wood increase and makes rainforests that function to protect the environment threatened with loss as well as the ecosystem in it. One material that is suitable for replacing wood is bamboo. Bamboo is easy to plant, breed, fast in growth, and of course the price is relatively cheap. The hollow or empty interior of bamboo often makes it difficult for users to utilise bamboo, therefore bamboo lamination technology is applied to facilitate the manufacture of building construction components. The purpose of this study is to determine the shear strength value of bamboo laminates using PVAc adhesive and epoxy resin adhesive and to determine the damage pattern on bamboo laminated beams after shear strength testing when using PVAc adhesive and Epoxy Resin adhesive. The tests carried out refer to SNI 03-3400-1994 using test specimens in the form of laminated bamboo beams with 2 variations of lamination, namely with PVAc and epoxy resin adhesives. Based on the tests carried out, the shear strength of laminated bamboo beams using epoxy resin adhesive is stronger with an average value of 6.7206 MPa compared to laminated bamboo beams using PVAc adhesive with an average value of 2.7949 MPa. The damage pattern that occurs in the adhesive part is damaged during maximum load with the bamboo slats detaching from the adhesive in the epoxy resin adhesive and in the PVAc adhesive the glue part is lifted.

Abstract

In the construction industry, concrete is an important component and is frequently utilized as a building material. Coarse and fine aggregate make up the majority of the content in concrete. Although some earlier researchers have replaced aggregate in concrete, advancements in industry and time have made it possible to replace aggregate with waste as well. The impact of substituting fine aggregate in a concrete mixture with a quality of 20 MPa with 25% and 50% crumb rubber is investigated in this study. Concrete's compressive strength was tested using cylindrical specimens that were aged 3, 7, 14, 21, and 28 days, while its flexural strength was tested using specimens in the shape of beams that were aged 28 days. The concrete compressive strength test reduced by 58.85% at a 25% crumb rubber content and by 78.73% at a 50% crumb rubber content, according to the test findings. Concrete's flexural strength, on the other hand, decreased by 23.66% and 49.23% for concrete with a 50% crumb rubber content and 25% crumb rubber content, respectively. This means that crumb rubber can be used in concrete mixtures for non-structural purposes. <w:LsdException Locked="false" Priority="50" Name="Gri

Abstract

Building and non-building construction generally uses reinforced concrete using conventional methods. Over time, this method has evolved and given rise to other approaches such as precast and prestressed methods. However, these methods still have some drawbacks, such as the relatively high density of the material and its impact on other aspects of the structure. New innovations are emerging to solve these problems, such as super lightweight panels with a material density of around 650 kg/m3. This study aims to examine other structural components, namely beam and column structures by comparing the reinforcement requirements and deviation of two buildings with different types of floor plates. The tests were conducted using an analytical approach using ETABS software. The results showed that the average ratio of beam reinforcement between superpanel plate and conventional plate was 77% and column was 94%. The average ratio of X-direction deviation between superpanel plate and conventional plate is 94% and Y is 88%.

Abstract

Climate Central predicts that Banten's northern coastal land will disappear by 2030. Previously, Banten has lost more than 1 kilometer of its former land. The purpose of this research is to obtain a prediction model for the evolution of the coastline between Tanara Beach (Serang Regency) to Tanjung Kait Beach, Mauk (Tangerang Regency). The method used for this research is the One-Line Model method. Based on the coastline prediction model of segment 1, Tenjoayu progressed from 2025 to 2030. Shoreline retreat occurs significantly from 2020 to 2030 around Pedaleman. The modeled shoreline around Pedaleman to the western part of Cup Island progressed significantly from 2022- 2030. The shoreline in segment 2, East of Cup Island, progressed from 2025 to 2030. West of the Ci Manceuri Estuary, the coastline retreats significantly from 2022 to 2030. East of the Ci Manceuri Estuary, the coastline tends to stabilize. Around Tanjung Kait Beach, the shoreline pattern advances significantly each year from 2022 to 2030.
