Abstract

Plastic waste is a material that is difficult to decompose when buried in the ground. The large amount of plastic waste from human activities can cause environmental pollution. The reason for designing this plastic trash chopper is because the price of machines that have been marketed has an expensive price. Prices on the market range from around Rp. 18.000.000 to Rp. 30.000.000 depending on the engine specifications. In addition to the price of the machine i tu own, reasons that become the background count tool design plastic waste is due to concerns about trash, especially plastic waste in the city of Palembang, which until now still cannot be solved by optimal. To overcome these problems, a redesign of a plastic trash chopper was carried out using the Value Engineering method. From the results of research and analysis is known that p e designof the machine counter trash plastic the profit that as many as 8 benefit with b iaya value of VE were issued at 5.44. The total costs incurred after the redesign was carried out, amounting to Rp.1.470 .000.

Abstract

The lack of supporting infrastructure facilities such as the Laboratory at Samudra University, especially in the Civil Engineering Study Program, Faculty of Engineering, has resulted in Iskandar Thani Institute having to work hard in building infrastructure to keep pace with advances in technology and science. This study aims to plan the dimensions and reinforcement of beams, columns, plates and stairs in the Civil Engineering Laboratory building. The laboratory building to be analyzed has a total of 3 floors with floor dimensions of 43 m x 27.49 m. Modeling and analysis of the structure of this building is assisted by the SAP2000 program using the Special Moment Bearing Frame System (SPRMK) and is designed according to SNI 03-1726-2012, SNI 03-2847-2013, and PPPURG 1987. The structure is planned to use concrete quality fc' 30 MPa and steel grade fy 400 MPa. The results of the analysis obtained that the floor slab thickness was 13 cm using D10-200 mm reinforcement for main reinforcement and D10-300 mm for split reinforcement. The thickness of the roof slab is 12 cm using D10-200 mm reinforcement for main reinforcement and D10-300 mm for split reinforcement. The dimensions of the B1 beam are 50 cm x 70 cm using 12D25 for the support area with D10-80 mm braces and 8D25 reinforcement for the field area with D10-120 mm braces. Begel B2 30 cm x 50 cm using 4D25 reinforcement for the support area and field with braces for D10-200 mm field and braces for D10-100 mm support. The dimensions of the K1 column are 60 cm x 80 cm using 10D25 reinforcement with D10-300 mm begel. The dimensions of the K2 column are 60 cm x 60 cm using 8D25 reinforcement with D10 -200 mm begel. The thickness of the ladder plate and landing was obtained 13 cm using D10-200 mm reinforcement.
