Abstract

: As the times develop portland cement became a very important material and it widely used to build various infrastrcture. However the process of making cement would cause a big problem which is releasing carbon dioxide (Co2) into the atmosphere freely which resulting in the depletion of the ozone layer. Geopolymer mortar was a mixture of which the basic material did not use the portland cement as a binder. Did to find out the effect of the use of geopolymer marls a study was conducted using experimental methods. The purpose of this study was to determine the effect of NaOH contentration strength of marl geopolymer mortar. Cube specimens measurring 5 x 5 x 5 cm3 with molarity variations 8M,10M, 12M, 14M, and 16M as many as 75 specimens. Mortar curing by drying it at room temperture, at ages 3, 7, 14, 21, and 28 day. From the results of the research, the maximum density of geopolymer mortar was obtained at the age of 28 day using a 16M activator ratio of 2,30 grams, and the maximum compressiv strenght value of geopolymer at 28 days using a 16 M activator ratio was 8,13 Mpa. It could be conclouded that the higher molarity was used in the mixture then the mor OH- was presesnt in the mixture so that the process the bind ing would go much faster.

Abstract

This study discusses the comparison of the size of coarse aggregate to the compressive strength of SCC concrete which aims to determine the effect of good coarse aggregate size on the characteristics of SCC concrete. SCC is a fresh mix of concrete which is more fluid than normal concrete, the concrete can flow and compact itself to every corner of the building without the need for compaction equipment. The SCC concrete method in this study uses a superplasticizer which is added by chemicals and influences the size of the coarse aggregate. With the addition of 1.5% Superplaticizer to the weight of cement, the test on SCC concrete was seen on the compressive strength with the influence of aggregate size and Superplasticizer. The composition in making SCC concrete is cement, 3 (three) sizes of coarse aggregate, fine aggregate, water and superplasticizer, the highest compressive strength is the size of coarse aggregate 3cm aged 28 days due to the characteristics of coarse aggregate, the larger the split size, the harder the concrete texture. This solution causes the compressive strength of SCC concrete to be higher

Abstract

Erosion and sidimentation are processes that occur continuously in river flows. The hose watershed is one of the watersheds that often experiences erosion. This is due to land clearing triggered by a rapid increase in population in the selangis watershed. In this study, we used a USLE method based on a geographic information system by calculating erosion rates that consider erosivity factors, erodibility, slope factors and slope lengths, land cover factors and conservation-specific action factors. The rainfall data used in the settlement can be obtained from PTPN 7 Pagar alam. From the results of the calculation, the value of the Elapsivity Index (EI30) was 863,017 N/h. Watershed area (1) 2,583,8625 ha, watershed (2) 6,897.5 ha, watershed (3) 464,375Ha, watershed (4) 666.0625 ha, watershed (5) 2,555 ha, watershed (6) 4,607.0625 ha. And the minimum erosion is 10,775 tons/year, the maximum erosion is 110,360 tons/year,because of the large erosion, sedimentation occurs and conservation is needed to overcome it.'

Abstract

Reservoir is a water storage building before distribution to customers or the public which can be placed underground or above ground in the form of a tower or towers Clean water management in Temu Karya , Padang Temu Village. Managed by the residents of Temu Karya. The Padang Temu Village Reservoir has a capacity/volume of 535.07303 m3 which is sourced from a spare spring. The research aims to determine whether the current reservoir capacity is still able to meet the increasing demand for clean water throughout the year based on population projections from 2022-2027. The population of Temu Karya in 2022 will be 545 people. The results of the projected population until 2027 are 686.5495 people using the linear arithmetic method. The current reservoir in Padang Temu Village is sufficiently capable of serving the community optimally for 24 hours, because water can be flowed continuously. Based on this study it can be concluded that a reservoir measuring (9.72 x 9 x 7 m) is sufficient water, and if in the following years there is a shortage of water capacity, the residents of the Padang Temu Village must look for new sources of water to overcome the shortage of clean water caused by a significant population growth.
