Abstract

This study discusses the comparison of the compressive strength of concrete using various types of fine and coarse aggregate origin from three different locations. Fine and coarse aggregates are taken from Mount Gamalama, North Maluku Province, Aggregates from Mount Merapi, Sleman Regency and Aggregates from Progo River, Kulon Progo Regency. The purpose of this study was to determine the use of aggregate types from these three locations in applications in high strength concrete. Aggregates are first tested for the physical and mechanical properties needed. The sample used in this study is cylindrical in size with a diameter of 15 cm with a height of 30 cm as many as 27 test objects. When the concrete is still fresh, a slump test is used to determine the workability value which is then tested for concrete compressive strength at the age of 7.14 and 28 days. From the results of this test, all concrete from these three locations can be used for high strength concrete above 50 MPa with aggregate from Progo River producing the highest concrete compressive strength.

Abstract

Sanitation is a problem of big cities related to its domestic waste water. In the city of Surakarta, the wastewater treatment plant of Semanggi is a centralized wastewater treatment system covering the south area of the city that consists of 28 villages with 9323 customers of home connections. This study examined the useful life of the services of the Semanggi plants based on the volume of water use and waste water. The study applied a descriptive method and resulted in only 17% - 26% of domestic wastewater in the service areas that could be treated by the plant having capacity of 60 liter/second in the year of 2017. Based on the projection of customers, for water use by 170, 160, and 150 liter/person/day, the waste water treatment plant of Semanggi will only treat the waste water by the year of 2020, 2022, and 2024 respectively.

Abstract

Pressuremeter Test (PMT) is an in situ method of soil investigation that is used to determine the pressure and strain behavior of the soil or rock. At pseudo-elastic phase, this behavior can be described by the PMT’s output parameter, modulus presurremeter (EPMT). It has been realized for a long time that EPMT cannot be used directly to describe modulus elasticity (E) from the ground so a correction is needed. Menard and Rousseau suggested that Menard's α Factor be used to correct the value of EPMT that determined empirically according to soil type, density conditions, and deformation behavior of soil or rock when given pressure (rheological properties). Therefore, it is necessary to study PMT behavior along with Menard's α Factor values in a variety of more specific sample types. In this study Back Calculation will be performed on the value of E from PMT testing on limestone sedimentary rocks by remodeling PMT using Finite Element Method (FEM). Back Calculation is a mathematical recalculation process of estimating the value of a data from an event along with related parameters. The results of the study show that there is a good correlation between the modulus of elasticity of the results of PMT and the modulus of elasticity of the Back Calculation. Menard correction factor in this study is consistent with the results of previous research that is equal to 0.47 where this value increases with the increase in the depth of the test sample.

Abstract

Armour layer is the type of gravel bed composed on the bed surface with pores between the composing grains as the place of sand to stay and lock the pores. This research was carried out in the Hydraulic Laboratory by using the main infrastructure of sediment flume from Plexiglas in 0.60 m width, 10.00 m length, and 0.45 m height dimension. The base gradients used was parallel to the water surface gradients, which were 1%, 1.4%, 1.8%, 2.2%, and 2.6%. The constant flow debit was at 25 l/s, 30 l/s, 40 l/s and 45 l/s capacity. The materials consisted of sand and gravel and were evenly mixed in 5 different grain size variations. At each running, there were 2 phases of occurrence: eroded surface and equilibrium. The instruments used during the running were digital current meter, point gauge, and sediment traps.The results of this research indicated armour layer formula stated in un-dimensional number with an average bedload limit of 0.8 mm to 2.9 mm, uniformity coefficient of 2.5 to 5, and critical shear stress of 0.61 N/m2 to 2.7 N/m2. and with minimum base shear stress of 6 N/m2.

Abstract

Drought was yearly disaster which often happen at region of Indonesia. In this reseaech, we observe in Wonogiri especially Alang Watershed, located at southwest of Wonogiri dam and between Plumbon and Serenan district. The purpose of this research is to find the value of drought index using Normalized Difference Vegetation Index (NDVI). The drought is detected by using the debit. So, then created the relations of  drought index and debit. Next, mapping the drought area in Alang watershed using software ArcGIS.Collecting data is the first step of this research., then analyze the data and doing validation test using RAPS method. Calculating the rain area using polygon thiessen. NDVI value is obtained from processing the Landsat 7 and 8 image with Arcgis. Classifying NDVI value based on Peraturan Menteri Kehutanan RI nomor P.12/Menhut-II/2012. Calculating debit using NRECA. Then, creat the relation chart between drought index and debit. Mapping the drought area from the month which had lowest NDVI value and had lowest debit. Also mapping the drouht from 2008-2017.knowing the drought area in Alang watershed and knowing the realtion chart between drought index and debit are the purpose of this research. The result showed that the relation chart of drouht index and debit aren’t good to detecting the debit. The distribution of drought area is obtained from processing the Landsat 8  image with variative distribution and more accurate result.
