This study aims to determine the resistance of rice husk geopolymer mortars to sulfuric acid. This research was conducted using experimental methods, namely by conducting experiments in the laboratory. Cuboid specimens measuring 50x50x50 mm, using binder: fine aggregate ratio is 1: 1.5, activator: precursor ratio 1: 1 and the ratio of Na2SiO3 and NaOH is 2: 1. Mortar immersed for 20 days with immersion of 5%, 10% and 15% sulfuric acid concentration. The compressive strength of the free geopolymer mortar is 9.20 MPa, sulfuric acid soaked with geopolymer mortar with a concentration of 5% is 5.00 MPa, immersion with a concentration of 10% is 4.60 MPa and immersion with a concentration of 15% is 2.00 MPa. From the compressive strength test results showed that there is a decrease in compressive strength of mortar exposed to sulfuric acid, the more concentrated sulfuric acid concentration, the lower the results of the geopolymer mortar compressive test results. This can be seen in the compressive strength concentration value of 5% decreased by 45.65%, the concentration of compressive strength of 10% decreased by 50.00% and the concentration of compressive strength of 15% decreased to 78.26%.

On several roads in the city of Pagar Alam the road narrowing occurred. In particular, on Bridges often cause problems such as congestion, queues, and delays, it is necessary to know the behavior of traffic flow characteristics such as Volume, Speed, and Density. The primary data survey on the Ayek Bridge section of Jalan Kapten Sanap, Pagar Alam City, was carried out for two Sundays and Mondays with the Manual Count method. Data analysis was based on the 1997 Indonesian Road Capacity Manual (MKJI) using Microsoft Excel software. As for the results of the study obtained the traffic volume for road type 4/2 D (before narrowing) road capacity of 5,643 pcu / hour perlajur, with a value of degree of saturation of 0,15 and service level Type A. Road type 2/2 UD (narrowing) road capacity of 2375 pcu / hour perlajur, with a value of Saturation 0.38 and Service Level Type A, 4/2 UD type road (After Refinement) road capacity of 5130 pcu / hour of service, with a value of 0.20 saturation and level Type A service. The biggest shock wave is obtained on Monday at 07.00-08.00 WIB which is -119.18 km / hour. Negative value is a backward forming shock wave, a backward shock wave occurs towards the arrival of the vehicle. The term 'retreat' means that with time, the shock wave will move backward (upstream or in the direction opposite to the traffic perger). The term 'formed' means that with time, congestion will increase upstream.

In general, concrete is composed of cement, fine aggregate, coarse aggregate, water and additional substances if needed. But along with the development of science and technology, concrete constituent materials can also change or be combined with organic or inorganic materials such as plastic waste materials and others. HDPE Plastic (High-Density Polyethylene) Is a type of plastic that is usually used to make milk bottles, detergent bottles, shampoo bottles, moisturizing bottles, oil bottles with code No. 2., toys, and some plastic bags. PET (Polyethylene Terephthalate) PETE or PET is one of the plastics used for food containers, bottles of mineral water and several other wrappers. This plastic is designed for one-time use only. With the use of HDPE and PET plastic waste at a percentage of 20% for concrete compressive strength was not achieved, normal concrete = 15.88 concrete B.HDPE = 12.01, B.PET = 11.71, BC = 12.39 but for concrete weight decreasing, normal concrete = 2330 kg, m3 B.HDPE concrete = 2122 kg, m3, B.PET = 2128 kg, m3, BC = 2096 kg, m3. For the composition of the optimum concrete mixture of the three compositions (B.HDPE, B.PET, BC) obtained the composition of BC which has the most optimum value of 12.39 Mpa, but does not reach the compressive strength of the plan of 15 Mpa.

Development in the field of construction in the modern era shows a very rapid development, including in the construction of housing, offices, hospitals and so on. Concrete as a construction material has long been used and widely applied by the community because it has advantages easily formed according to construction needs. The development of concrete technology has also continued to develop with the presence of high-strength concrete. The process of making lightweight concrete certainly requires mixed materials that have low specific gravity. One alternative material that can be used is newsprint and fly ash, both materials are materials that have a low specific gravity and are easy to work on, the addition of fly ash and newsprint so that the relationship of compressive strength and weight of concrete influence each other, the more addition of fly ash and newsprint, the compressive strength increases and the weight of the concrete increases.

One alternative material that can be used is newsprint and fly ash, both materials are materials that have a low specific gravity and are easy to work on, the addition of fly ash and newsprint so that the relationship of compressive strength and weight of concrete influence each other, the more addition of fly ash and newsprint, the compressive strength increases and the weight of the concrete increases.","PeriodicalId":17796,"journal":{"name":"JURNAL ILMIAH BERING'S","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78514697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
