Abstract

Column collapse can be overcome by increasing the nominal strength of the cross section, one of which is by strengthening using FRP (Fiber Reinforced Polymer). This research will focus on the effect of using mendong plant fiber as a fiber jacket for strengthening reinforced concrete columns after building damage. Starting from material testing, mix design calculations, making test objects and testing test objects. There are 3 variations of test objects, namely concrete without a layer of Mendong fiber, concrete with 2 layers of Mendong fiber and concrete with 4 layers of Mendong fiber. The number of test objects was 15 concrete cylinders and 6 reinforced concrete columns. Reinforced concrete column specimens were subjected to axial testing to obtain the maximum axial load. Based on the test results, it was found that the average axial strength of reinforced concrete columns without mendong fiber blanket was 120.03 kN, the average axial strength of post-damaged reinforced concrete columns with 2 layers of mendong fiber blanket was 134.46 kN and the average axial strength of post-damaged reinforced concrete columns damaged with a 4-layer mendong fiber blanket of 144.83 kN. The greater the number of layers of mendong fiber, the axial strength of the post-damaged reinforced concrete column will increase with an increase of 12.02% for 0 layers to 2 layers, and 7.71% for 2 layers to 4 layers. Based on the results of this research, mendong fiber can be used as an alternative to fiber jacket for reinforcing reinforced concrete columns after building damage.

Abstract

The needs of construction workers play a very important role in society. However, based on the results of a survey of several construction workers from Gunungpati Village, problems were found such as never having received socialization and training, not having a craftsman skills certificate, lack of interest in learning and literacy among the residents, not really knowing the construction workers from Gunungpati Village and marketing of construction worker services is still conventional. To answer these problems, PPK Ormawa BEM Faculty of Engineering, University of 17 August 1945 Semarang implemented construction worker empowerment programs in the Gunungpati sub-district such as the "Construction Worker Socialization and Training" program, "Construction Worker Certification", construction of the "Construction Education House", "Gunungpati Building Cities” and “Marketing Online Construction Worker Services”. The results obtained from the implementation of the program were that 68 construction workers had received socialization and training, 10 construction workers had BNSP light steel applicator certificates, 28 construction workers had paint applicator certificates, a construction library was built, namely the Construction Education House, an increase in interest in learning from 33 % to 74%, increase in the level of recognition of construction workers from Gunungpati sub-district from 56% to 82%, marketing of online construction worker services using 3 social media, namely Instagram, Facebook and Whatsapp, and 10 construction workers have been ordered to construction companies. Apart from that, it produces a spirit of independence and awareness of the potential of society. Formation of construction workers' associations and collaboration between implementation teams, student organizations, universities, communities, sub-districts, departments, associations, construction companies and vendors.
