Abstract

In daily life, plastic waste feels very close to us as humans. This type of waste is very difficult to decompose,which significantly disrupts both life on land and in the ocean. In this study, the use of heated plastic waste as an additive incement mixtures for making paving blocks is still rarely explored. The aim of this research is to examine the impact of usingplastic waste as an additive in cement mixtures. Additionally, the use of plastic waste as an additive in cement is based on theidea that plastic waste can be transformed into something useful to reduce the troubling amount of plastic waste. For this purpose,this study employs both the Literature Review Method and the Experimental Method to determine how the addition of plasticwaste in paving block mixtures affects the compressive strength of the paving blocks. In this study, plastic waste will be used asan additive to cement with the following compositions: 0% (ordinary concrete), 2.5%, 5%, and 7% of the cement weight. Theresults showed that paving blocks with a 2.5% plastic mixture achieved the highest compressive strength of 26.2 MPa at 21 days,while the highest water absorption was observed in the 5% plastic mixture, with a value of approximately 6.14%. Overall, thetotal strength exceeded the planned compressive strength of 20 MPa based on the SNI 03-0691-1996 standard, making it suitablefor road use with a B quality grade.

Abstract

Islamic Boarding School Hidayatul Muslimin 1 is situated in West Kalimantan Province. This school features 19 classrooms constructed from basic wooden structures. The educational facilities available at this school, including tables, chairs, blackboards, and shoe racks, were insufficient to facilitate effective learning; some students even had to sit on the floor due to the lack of teaching and learning facilities. In addition, the classroom walls look dull because the paint has faded, so they display the original color of the wood that is the material of the classroom walls. This Community Service initiative aims to create learning facilities that will not only foster a comfortable learning environment for students but also enhance the practical skills of Civil Engineering students in woodworking applications. The Community Service team and Civil Engineering students who practiced woodworking at the Civil Engineering Department Workshop at Pontianak State Polytechnic executed the project to create these educational facilities. The learning facilities created for Hidayatul Muslimin 1 Islamic Boarding School in West Kalimantan include 20 tables, 40 chairs, two whiteboards, and four shoe racks. Additionally, with the support of Civil Engineering students, several teachers, and students from the Islamic boarding school, the Community Service team renovated and painted two classrooms.

Abstract

The development of apartments is very suitable for the millennial lifestyle, which heavily relies on technology,comfort, and compact yet functional home design, especially due to the economic growth of society and thesurge in productive age and millennials. These apartments are planned in Kubu Raya Regency. The structuraldesign is one of the most crucial elements of building planning; reinforced concrete will be used in thebuilding's construction.. The building structure consists of Roof Slab, Floor Slab, Beams, Columns, andFoundation. This apartment structure has five levels, each measuring four meters in height.. This apartmentbuilding is designed to withstand earthquakes and is located on Major Alianyang Street, Kubu Raya Regency,West Kalimantan Province. Earthquake planning uses response spectrum according to SNI 1726-1029. Loadcalculations are in accordance with SNI1727-2020 and PPURG 1987. The requirements for structuralconcrete of the building are according to SNI 2837-2019, and the chosen calculation method for this buildingis the Medium Moment Resisting Frame System (SRPMM). From the calculation results, the thickness of theroof slab and floor slab is 13 cm; sloof beam with dimensions of 35 cm x 70 cm; main beam with dimensionsof 30 cm x 60 cm; secondary beam 1 with a thickness of 20 cm x 40 cm; secondary beam 2 with a thickness of30 cm x 15 cm; column with dimensions of 70 cm x 70 cm; shear wall with a thickness of 30 cm; pilecapfoundation size is 350 cm x 350 cm x 700 cm, while the dimensions of the minipile are 40 cm x 40 cm.Keywords: Reinforced Concrete Structure, Structural Planning, 5-story Building
