Abstract

Plastic represent thousands of materials with different physical, mechanical, and chemical properties. As plastic demand and usage increase, it is undeniable that the amount of plastic waste will increase. Plastic has the features of which cannot rot; it does not decompose naturally; it cannot absorb water or cannot rust. So it will eventually cause problems for the environment. This study aims to determine the compressive strength and tensile strength of concrete mixes that use coarse aggregates of plastic waste as a substitute for natural aggregates / broken rocks. There are three variations of samples made with mutations in the type of plastic used, namely PP (Polypropylene) plastic, PET (Polyethylene Terephthalate) plastic, and PP & PET combination plastic. The specimen is cylindrical, with a size of 10 cm x 20 cm. Compressive strength and tensile strength testing is carried out at 28 days according to SNI standards. The results obtained the compressive strength obtained on each variation of standard concrete samples, PP aggregate concrete, PET aggregate concrete, and PP & PET aggregate concrete, respectively, of 21.64 MPa, 10.61 MPa, 8.48 MPa, and 10.18 MPa. Whereas for the splitting tensile strength of standard concrete, PP aggregate concrete, PET aggregate concrete, and PP & PET aggregate concrete respectively were 2.86 MPa, 1.80 MPa, 1.70 MPa, and 1.80 MPa.

Abstract

Computer-based technology has pervaded practically every aspect of human life in the modern era. Through diverse information systems, various fields have employed computer-based technology to build theories and their applications. Geographic Information System (GIS) technology is one type of computer-based system that is widely employed. Various disciplines can use Geographic Information System (GIS) technology to research and map flood zones. The research approach employed is the employment of ARC GIS 10.5 system technology to determine the flood zone's features. Pampang, Tamamaung, Sinri Jala, and Karuwisi Utara are four villages that are flood-prone locations that are included in the warning zone, according to the results of data processing using GIS software and data analysis illustrated from mapping the flood area in Panakkukang District. There are 1,985 hectares in the Rappocini sub-district, which is included in a vulnerable region, namely Bantabantaeng Village, and 145,709 hectares in Karunrung Village, Gunung Sari, Bontomakkio, Tidung, Kassi-Kassi, Mappala. Parts of the Manggala, Bangkala, and Borong regions, as well as sub-districts of Manggala, are included in the vulnerable areas. Tamalanrea Indah, Tamalanrea Jaya, and Tamalanrea sub-districts are the Tamalanrea sub-districts that have been designated as vulnerable zones.

Abstract

This research aims to determine the value of mechanical properties in fiber fibers which are submerged in seawater and to find out the optimum length of fiber fibers to the mechanical properties of fiber fibers which are submerged in sea water. The method used is an experimental method carried out in the laboratory by varying the length of the fibers, which is 25 mm; 50 mm; 75 mm; and 100 mm with 4% fiber addition. Tests of mechanical properties carried out in the form of compressive strength, split tensile strength, and flexural strength. The results of the research challenge the palm fiber-concrete that the longer the fibers used in the concrete, the mechanical properties decrease. Fiber concrete submerged in seawater has higher mechanical properties than normal concrete. Optimum fiber length length in fiber concrete from the results of this study is 25 mm.
