Abstract

Concrete is a building material consisting of a mixture of coarse aggregate, fine aggregate, cement, water and other additional materials (Firdaus, 2019). Concrete materials come from nature (gravel, sand and aggregate) which will eventually run out because they cannot be renewed. Therefore, the use of concrete materials needs to be innovated to become green concrete or environmentally friendly concrete. Environmentally friendly concrete is made using waste or comes from industrial waste materials. One of them is replacing aggregate with materials that do not damage the environment, such as Polyethylene Terephthalate (PETE) plastic pellets. PETE plastic pellets are a type of plastic material that has wrinkle-free fibers. This material is often used for packaging food and drinks such as bottles of soft drinks, mineral water and so on. The aim of this research is to determine the influence and trend of compressive strength of fc'20 MPa concrete on replacing some of the coarse aggregate with PETE (Polyethylene Terephthalate) plastic pellets varying 10%, 20% and 30%. The research method used was to make cylindrical test objects of each variation and then test them at the age of 7 days, 14 days and 28 days. The compressive strength test results for concrete variations of 10% PETE at 7 days, 14 days and 28 days were 21.84 MPa; 22.78 MPa and 24.35 MPa. In the concrete test variation of 20% PETE aged 7 days, 14 days and 28 days was 21.03 MPa; 22.09 MPa and 23.21 MPa. The compressive strength test for concrete variations of 30% PETE aged 7 days, 14 days and 28 days was 20.22 MPa; 20.71 MPa; and 20.95 MPa. These results show that the test object produces concrete compressive strength exceeding FC 20 MPa with an increasing trend from 7 days - 28 days.

Abstract

Human resources (man) as the main construction resource must be professional, competent and certified. Certificates for construction workers are clearly stated in Government Regulation Number 14 of 2021 concerning construction services. The Government Regulation requires workers in the construction sector to have a work competency certificate and construction service actors to employ construction workers who have a work competency certificate. Construction service actors are expected to have a work competency certificate (SKK) in accordance with job qualifications and education levels.   The phenomenon is that some SKK ownership is not in accordance with the level requirements stipulated in the Perpres No. 8/2012 regulation. The purpose of this study is to determine the suitability of education for the 4-5 level work competency certification process in Semarang City. The research method used is qualitative with data collection of test results from TUK. The data analysis method used is coding analysis. The results of competency tests at levels 4-5 show that more than 50% of competency test participants have the latest education that is not in accordance with the requirements of Perpres No. 8/2012.

Abstract

Perkembangan Teknologi dewasa ini mengalami pertumbuhan yang sangat pesat. Perlunya peningkatan kemampuan suatu lulusan perguruna tinggi yang dibekali kemampuan hardskill dan softskill. Khususnya pada matakuliah hidrologi, drainase dan kualitas air yaitu software SWMM. Kegiatan pelatihan ini memberikan pemahaman dan kemampuan pengembangan softskill bagi mahasiswa. Pelaksanaan Pelatihan menggunakan metode ceramah, demonstrasi/praktik dan melakukan evaluasi dengan memberikan kuesioner pre-test dan post-test yang diberikan di awal kegiatan dan setelah diberikan pelatihan software SWMM (Storm Water Management Model). Pelatihan ditujukan kepada Mahasiswa Teknik Sipil. Tutorial menitikberatkan pada pemodelan,persiapan pengisian parameter yang dibutuhkan seperti data hujan, data penampang saluran, kemiringan saluran/slope, yang tidak kalah penting adalah arah aliran serta elevasi pada junction saluran. Nantinya akan dilakukan simulasi sehingga dapat menghasilkan output berupa debit banjir. Berdasarkan hasil kegitaan pelatihan diperoleh hasil bahwa kegitana PKM ini efektif dalam meningkatkan kemampuan dan softskill yang dapat menjadi bekal dalam mempersiapkan diri jika nantinya masuk pada dunia kerja. Hasil capaian berdasarkan kuesioner pre-test sebesar 26% setelah dilakukan pelatihan mengalami peningkatan menjadi 98%.

Abstract

Risk management is defined as a systematic process that includes planning, organizing, leading, and controlling organizational activities to minimize the likelihood of revenue loss. PT Mustiko Klopo Jati faces challenges related to improving construction risk management practices. The implementation of this activity is carried out in the Bulog Warehouse Construction Project. The objective of this community service program (PKM) is to provide risk management training with a focus on the preparation of the Construction Safety Plan (RKK). This training aims to enhance participants’ knowledge in preparing RKK documents in accordance with the latest regulatory standards. Before the training, 48% of participants had a limited understanding of the RKK preparation process; following the training, the level of understanding among construction practitioners increased to 85%. It is expected that this activity will provide solutions to the identified problems and foster effective collaboration with industry partners, thereby contributing to innovation in the implementation of efficient and appropriate construction practices.
