Abstract

One of the building materials that has developed very rapidly is concrete. Some of the advantages of concrete include the relatively low price, high compressive strength, rust resistance, easy transport and printing, and are relatively resistant to fire. There are several ways that can be used to make concrete light, including the use of lightweight aggregates, foam agents, coconut fibers and additive types "x", where coconut fiber waste has not been used optimally. In this study a lightweight concrete mixture of additive type "was made using x 5M additive products, foam agents and coconut fibers using a cement content of 650kg / m3. The variation of the "x" additive is 2%, 4%, 5%, foam agent is 2.5%, 3%, 4% and coconut fiber is 15%, 20%, 25%. with the treatment conditions for the specimens for 28 days soaked and not soaked. Test objects are made of cubes with a size of 15x15x15cm. This study is to determine the weight / m3, the compressive strength of the lightweight concrete produced. The results showed that the increase in the use of additive types "x", foam agents and coconut fibers caused the weight of the concrete to be heavier and compressive strength. The highest weight of this lightweight concrete at the age of 28 days is not immersed in 1.867 kg / m3, while the lowest is 1.665 kg / m3. The test object for non-soaked conditions has a better compressive strength of 324 kg / cm2 than the test object with the condition soaked press test which is 293 kg / cm2.

Abstract

In Indonesia, there are many infrastructure developments in the form of bridges, parks and buildings. For many facility buildings that are built are health facilities, the construction of which is one of them is a laboratory and clinic located in the city of Medan. The area has an earthquake acceleration of 0.5g which has a moderate earthquake risk. In the analysis of the structure of the building, earthquake analysis was carried out with dynamic earthquake analysis of spectral responses in ETABS software, and manual calculations for dynamic earthquake forces with mathematic MDOF methods were carried out, and special moment frame frame (SRPMK) requirements were used. In this building, the strong column weak beam is prioritized, and has fulfilled the requirements to be said as a strong column weak beam, namely ? Me / Ø> 1.2 for Mnb / Ø 1110.62> 562.61 for columns 500 x 500 mm and 2606.15> 987.67 for columns 600 x 600 mm . And obtained the amount of reinforcement needed in this structural building including for floor slabs and roof used D13-200mm, beams 600 x 400mm used 4D22 and 2D22, beams 700 x 400mm used 6D22 and 3D22, joists 350 x 250mm used 5D22 and 3D22, columns 600 x 600 is used 12D22 and Ø12-130, columns 500 x 500 are used 8D22 and Ø12-130, the foundation is used pilecap size 2 x 2 x 0.9 m with reinforcement D25-110mm, and sloof with dimensions of 600 x 300mm used reinforcement 4D13 and 2D13.

Abstract

Clay mining activities at PT. Semen Indonesia (Persero) Tbk uses a Surface Mining system with tiered or layered mining methods. The clay mining activity in east kuari mliwang has produced 4-6 layers from the lowest elevation which is +0 meters above sea level (masl), with the opening of an area of ??27 hectares, from the results of mining that has been done. Each slope made must have safety factors that meet the standards set by the Ministry of Energy and Mineral Resources and the Indonesian National Standard (SNI) taking into account the efficiency of reserves that will be in the mine. The return analysis of slope stability was obtained based on the value of the safety factor of a slope using the Bishop Simplified method with the help of Rocscience Slide v6.0 software. Input data in the form of physical and mechanical properties obtained from laboratory testing. Determination of minimum safety factors using SNI 8460: 2017, ICS 91.010.01 for soil material, namely FK ? 1.5. The factors that affect slope stability at the study site are the physical and mechanical properties of the soil, the slope geometry, and the condition of the ground water table. The results of the calculation of slope stability safety factors at the study site have different results, for Block T-03, slopes with an overall height of 21 m, the overall slope angle of 27 ° has a FK value = 1.502. Block W-06, Slope with an overall height of 25 m, the overall slope angle of 27 ° has a FK value = 1.504. And Block Z-04, Slope with an overall height of 26 m, the overall slope angle of 30 ° has a FK value = 1.508. From the calculation results the average location of the study has a value of FK ? 1.5 which indicates the slope is in a stable condition.

Abstract

National Medium-Term Development Plan (RPJMN) targets 100% of the clean water access and sanitation for all Indonesian people, the program is valid for 2015-2019. Research was conducted to measure the RPJMN target achievement . The analysis was taken in North Surabaya city: Bulak and Krembangan Subdistricts, research methods used is by EHRA and the output used qualitative from Microsoft Excel with result reaching 100%. Societies obtained water sources from: bottled water, refilled water, and regional water supply (PDAM). PDAM water is used for dishwashing and brushing teeth, societies consider the water is not feasable. The difficulty level in obtaining clean water is 20.2% due to technical problems. Satisfaction level of PDAM water quality is 82%, while the remaining 18% are not. Occured problems: murky water after pipeline repairs, water clarity, larvae in a reservoir, and others. Societies reproccess the PDAM supply for consumption reaches 93%, it cannot be used directly.

Abstract

Plastic material is one of many materials that are difficult to decompose naturally and require hundreds of years to decompose completely. One way to reduce the volume of plastic waste is to process or recycle it. Plastic injection seeds (HDPE) is one type of processed plastic waste (HDPE). In this study using the concrete laboratory experimental method according to SNI 03-2834-2000. There are 2 stages in this concrete research, stage 1 is concrete with variations of quartz sand (20%, 30%, and 40%) to the weight of sand and the most optimum results are obtained in concrete mix with 40% quartz sand and 3% additive (TH1 / 40-28) which is equal to 613.1 kg / cm2 in the 28 day test, an increase of 42.34% from the compressive strength of normal concrete K300 of 430.73 kg / cm2. For phase 2, concrete with a variation of quartz sand is 40% and the addition of coarse aggregates from plastic seeds (HDPE) (20%, 30% and 40%) from the weight of gravel and find the most optimal results of concrete mix with 40% quartz, plastic 20% , additive 3% (TH2 / 20-28) which is equivalent to 359.5 kg / cm2 in a 28 day test, a decrease of 41.4% from the compressive strength of concrete stage 1 quartz sand 40% (TH1 / 40-28) from 613, 1 kg / cm2.
