Abstract

Solok Regency irrigation network planning which has an area of irrigation land of 3738 ha. The main canals are spread in several areas, namely 43 Irrigation Channels, 17 Dams, 7 Reservoirs and 2 lakes which are still functioning in Solok Regency. The poverty rate in Solok Regency is still quite high, reaching 27,487%. The data includes secondary data on 10-year rainfall data from Kayu Aro, Bayur Maritime Bay Methodology, Padang Panjang Geophysics and 10-year climatology from Kayu Aro Climatology Station. The calculation method used is the intensity of the issen rainfall method, Evapotranspiration of the modified Penman method, the reliable discharge of the DR.FJ Mock method, the cropping pattern, and the need for irrigation water. The most efficient and optimal planting pattern obtained is PADI-PADI-CORN with large irrigation water requirements in tertiary plots (NFR tertiary plots) ranging from 0 - 1,546 ltr / sec / ha with a maximum of 1,546 ltr / sec / ha in September II, whereas Irrigation water demand in the intake (DR intake) ranges from 0 to 2,378 ltr sec / ha with a maximum of 2,378 ltr / sec / ha in September II. The mainstay discharge available in the Pauh Tinggi Irrigation Network Planning is very abundant with the mainstay discharge (Q80) for irrigation, the maximum mainstay discharge (Q80) occurs in April I with 10.482 ltr / sec / ha and minimum in December II with 3,930 ltr / sec / ha. Based on the mainstay discharge results above it can be stated that the water balance / water balance between the mainstay discharge Q80 and the need for irrigation water experienced a large surplus.

Abstract

Bamboo Fiber is one of the materials that can be alternative as an added material to increase strong concretepress. The gypsum waste comes from the disposal of household flatfon dismantling, which becomes one of the added materials in the manufacture of cement. The use of both materials as concrete mixture subtitution is expected to reduce environmental pollution and exploitation of natural resources. This research aims to find out the influence of the use of SB as fiber and LG as cement subtitution semen on concrete mixture against strong concrete press. The study used a mixture of SB of 1%, 1.5%, 2%, and 3%of cement weight, as well as LG as much as 3%,and5% of cement weight. Strong press testing was conducted on the 14th and 28th days. The result of this study is that the higher percentage of SB and LG workability is decreasing. Strong press testing shows that all variations have a strong press yield of 1%B3%G above the normal concrete press strength and the rest under normal concrete. The highest press strong value is derived from the variation of 1%B3G with a mixture of 1%SB + 3% LG which is 20.81 MPa.

Abstract

Concrete is the result of the preparation of materials consisting of cement, aggregate and water. All the constituent materials of concrete are obtained from natural resources, which, if exploited continuously will be increasingly depleted. The use of waste as an added material or as a substitute material is a good alternative for mixing the building blocks of concrete. Extinguished lime is one of the materials for making cement where quenched lime is made without a fabrication process such as cement which produces waste during the fabrication period. As for ceramic or tile waste, it is one of the building wastes that cannot be used anymore so that ceramic waste can be used as a substitute for coarse aggregate in the concrete mixture. This study aims to determine the effect of using extinguished lime as a substitute for cement and ceramic or tile waste as a substitute for coarse aggregate in the concrete mixture on the compressive strength of concrete. This study used a cylindrical specimen measuring 15x30 cm as many as 40 samples from 4 mixed variations and added with 4 normal concrete samples which serve as benchmarks. This study used a mixture of lime substitute as much as 15%, and 25% by weight of cement, as well as ceramic or tile waste as much as 30%, and 60% of the weight of coarse aggregate. Where the concrete compressive strength test was carried out on day 28. The results of this study were that the resulting slump value was still in accordance with the mix design with a range between 60-180 mm with the highest slump value found in the variation of 15% lime + 60% ceramic waste, namely 15 cm.

Abstract

With the development of concrete technology in these days, concrete innovation is needed because it does not rule out the possibility of this concrete material, namely fine aggregate, coarse aggregate, cement, and water, which is decreasing over time or thinning. An innovation is needed that can reduce the use of cement by using other materials, so that the amount of cement usage can be reduced. Examples of innovation as a material that can be mixed with concrete include fly ash, palm ash, extinguished lime, bagasse ash and others. This is what drives research for concrete mixtures other than sand, gravel, cement and water, adding materials to the concrete mixture, namely limestone as a substitute for cement and plastic waste as a substitute for coarse aggregate. The use of limestone is expected to reduce cement levels and the use of plastic waste can reduce the use of gravel from river stones so as not to damage the river ecosystem. The addition of limestone and plastic waste is expected without reducing the strength of the concrete. This study uses the percentage of limestone made with a percentage variation from 0% to 15% (0%, 1%, 5%, 10%, and 15%) of the volume of cement based on experiments (mix design calculations) and for plastic waste with a percentage variations from 0% to 10% (0%, 1%, 5%, and 10%) of the crude aggregate volume based on my experiment (mix design calculations). The concrete is molded by using 4 cylindrical molds measuring 15cmx30cm for each test concrete quality. The compressive strength will be tested at the age of 14 and 28 days. The results of the research on concrete with additional substitution in the form of lime which was substituted into cement and plastic waste substituted for crude in coarse agrrates tended to experience a decrease in quality or compressive strength when compared to normal concrete without any added substitute materials. Research on the highest compressive strength value of concrete mixed with substitution material is the mixture or variation A (1% + 1%) with the average results of 20.27Mpa.

Abstract

Lime as a concrete mixture is done because lime contains elements of calcium oxide (CaO) which is the material for the manufacture of cement from 60-65% (Tjokrodimuljo, 2007). Glass waste comes from the waste glass industry has a silica content of 72.20% (Fikriansyah and Tanzil, 2013). The use of these two materials as a concrete mixture of substitution material is expected to reduce the pollution of the CO2 gas environment due to the burning of steam from the manufacture of cement and natural resources exploitation due to excessive aggregate mining. This research aims to determine the influence of sulphuric acid from 2% for strong concrete emphasis that contains glass in lieu of coarse aggregate and lime as a cement substitution. Penelitian ini menggunakan campuran lime dari 7% dan 10% dari berat semen, serta 5% dari limbah glass, dan 9% dari berat kerikil. Compressive strength testing is carried out on the 7th, 14th, 21th, and 28th days. Results of this study showed that the strong emphasis of concrete with a lime mixture of 10% + 5% Glass on 28 days obtained a strong press of 12.13 MPA higher than normal concrete ie 7.68 MPA on the 28th day.

Abstract

The change in the function of land to housing can cause a decrease in the level of the water absorption zone that occurs in the area and can cause inundation or even flooding. Housing can be categorized as good, that is, it must have drainage facilities that can drain rainwater quickly and not cause stagnation of water even though the rainfall is very high. Therefore, the right solution to tackle standing water, drainage problems, and flooding in Kertagraha housing is to create a retention pond because in the kertagraha housing there is no final storage system that is suitable for dealing with flooding,The location of this research is located in Sukarukun Village, Sukatani District, Cibitung, Bekasi Regency with the category of housing area. In this study, a hydrological analysis was carried out with rainfall data from the Rain Post Station located in Sukatani and the TRMM Rain Post located in Cikarang within a 10-year return period starting from 2010-2019, and the planned flood discharge data were obtained. Furthermore, hydraulic analysis is carried out to determine the flood discharge capacity in the existing drainage channels and to plan the volume of the storage pool. After that, the retention pond design planning is carried out.In the calculation analysis, it is found that the planned rain discharge value in the next 10 years is 7.393 m³ / second using the Haspers method. The total capacity of the storage pool is 12,385 m³, with the dimensions of the retention pond, namely P = 70m, L = 20m, T = 10meter. With a concentration time of 1675 seconds. Based on the analysis carried out and there is sufficient land, this retention pond is the best solution to overcome the flood problem in Kertagraha housing.
