ABSTRACTThis study aims to find out the volume of a flood plan and balance between sediment raised in themining of sand and sediment that comes in the time of flooding in kali Putih river’s area regional ofSrumbung. The method of study is using observation method, interview method, and literaturemethod. Hydrology data used in this study is map kali Putih river, map rain stasiun, and gradationof sand grains. To calculate the volume of a flood plan is using the rational method, weduwenmethod, and hasper method. And to calculate sediment transport using Mayer, Peter and Mullerformulation. The calculation based on 5 rain station Argomulyo, G.maron, Ngepos, Babadan, andKaliadem station using (1) Rasional, (2) Weduwen and (3) Hasper to 5 year reissue period are: (1)233,94 m3/sec, (2) 80,67 m3/sec, (3) 129,48 m3/sec. Tthe result of the calculation of sedimenttransport using Meyer, Petter and Muller formulation produces sediment transport base for theentire widht of the river of 4,66 m3/second, and base sediment transport for 1 hour of 16776m3.From the result of mining sediment of Srumbung area is 492750 m3/year. So the mining wasdone in Srumbung for 1 year is 492750 m3can be offset by during floods for 11,54 hours resultingheaps of 493214,4 m3.

ABSTRACTThis study aims to determine the chemical content Volcanic Ash Kelud and determinethe effect of volcanic ash that has burned at a temperature of 600ºC for concrete compressivestrength. Testing will be done on the physical properties and chemical composition of theVolcanic Ash content Kelud using Atomic Absorption Spectrometry (AAS) and Gravimetryinclude the content of Al2O3, Fe2O3, SiO2, H2O and LO1. This test refers to ASTM 618-03 andSNI 15-0302-2004. Further testing concrete compressive strength with three cylindrical concretespecimen with a diameter of 15 cm and a height of 30 cm to 28 days on each variant. Theaddition of volcanic ash Kelud varied with dose of 0%, 5%, 10%, 15% and 20% of the weight ofcement needed. Data were analyzed with descriptive-quantitative method to determine thefeasibility of volcanic ash in concrete production based on the requirements of new chemicalelements Pozolan nature. The results showed that of the test sample composition chemicalconstituents Volcanic Ash Kelud from Pringwulung village, Depok, Sleman qualify as naturalPozolan. The greater the increase percentage of volcanic ash on the weight of the cement, thecompressive strength of concrete produced increasingly large, the compressive strength ofconcrete against any variation on the addition of volcanic ash Kelud 0%, 5%, 10%, 15% and20% obtained compressive strength average amounted to 34.295 Mpa, 36.731 MPa, 41.881MPa, 42.767 MPa and 46.947 MPa. Where the maximum compressive strength of the concreteobtained with the addition of volcanic ash of 20% and a minimum compressive strength of theconcrete obtained with the addition of volcanic ash at 0% (No Addition).Keywords: Chemical Ingredients, Concrete Compressive Strength, Volcanic Ash Kelud

ABSTRACTThis study is aimed to discover the strong lighting at carpentry of Engineering Faculty UNYmainly at between 08.00 A.M.-02.00 P.M. Light is an absolute requirement for men to see theirworld. Natural lighting is the light which uses the direct sunlight. Artificial lighting is all forms oflight that comes from a tool created by humans. Mixed lighting is the fusion between naturallight and artificial lighting. The study was begun by studying the basic theory and standardmixed lighting in the carpentry, then do observation, measurement, drawing, determining thepoint of measurement and data collection Data collection was conducted by measurement usingLuxmeter's between at 08:00, 10:00, 12:00 , 02.00 P.M. The data collected in the measurementof as much as 3 times in the same hour. The findings indicate that the average yield stronglighting in the carpentry meet the standard (200 luv) in the amount of 427.13 lux (sunshine),357.00 lux (rainy weather), and 363.12 lux (cloudy weather). It is known from the study that thestrongest lighting in the carpentry when the weather is bright and the weakest lighting is 427.13lux and in wet weather it is 357.00 lux.Keywords: Carpentry, Illumination.

ABSTRACTThis research aims to know the capacity of split tensile strength of the mortar andlightweight mortar composition effective for wall with using pumice breccia. Pumice breccia is anaggregate that has a good thermal insulation and easy to obtain. In addition, pumice breccia islightweight aggregate that resistant to earthquakes. However, pumice stone has not been usedoptimally for structural elements. This research was conducted with the experimental method. Inthis study, there were 27 specimens that used for testing the split tensile strength of mortar.Each type of mortar mixture comprised of 3 compositions used were normal mortar 1PC: 4PS,1PC: 6PS, 1PC: 8PS ; normal mortar pumice 1PC: 2PS: 2PM, 1PC: 3PS: 3PM, 1PC: 4PS: 4PM; pumice mortar 1PC: 4PM, 1PC: 6PM, 1PC: 8PM. The proportion of the mixture obtained fromthe calculation of the volume of the test object is used. Each composition of the mixture wasmade 3 specimens with cylinders 150 mm x 300 mm. The results showed that the split tensilestrength avarage of normal mortar, normal mortar pumice, and pumice mortar were 0,16 MPa,0,10 MPa and 0,12 MPa. The analysis results show that the optimum split tensile strengthoccurs in normal mortar pumice. Therefore, the effective proportion mix of mortar with usingpumice breccia is 1PC: 3PS: 3PM.Keywords: Mortar, Pumice, Split Tensile Strength

ABSTRACTThis study aims to get the maximum compressive strength with high quality in determining theeffect of partial replacement of cement with bentonite to the compressive strength of concrete.This study was conducted by testing the chemical composition of the bentonite by using themethod of Atomic Absorption Spectrometry (AAS) and Gravimetry that refers to the ASTM 618-03. For testing the compressive strength of concrete it was used the age variation to assess thecompressive strength of concrete using 10% of bentonite as the partial replacement for cement.There were 18 samples consisting of three cylindrical concrete samples in each age variation(the diameter was 150 mm and the height was 300 mm) and the testing was conducted at theage of 3, 7, 14, 21, 28 and 56 days. The results showed that the test of bentonite chemicalcomposition in the Chemistry Analytical Laboratory of Gadjahmada University met therequirements of pozolan chemical. The highest compressive strength at the age of 56 days andat 28 days the lowest compressive strength were 49.454 MPa and 37.119 MPa respectively.The percentage of the optimum increase of concrete obtained at the age of 28 days to 56 dayswas 33.23%. Moreover the addition of bentonite gives the effect to the workability so that thevalue of the slump was lower than the that in the planning.Keywords: Bentonite, Compressive strength, Slump

ABSTRACTThe objectives of this studywas to solve the problem of floodwater due to the rainwater runoffand to reduce the flow rate of the runoff at the Colombo Street in front of the Faculty of SportScience, Yogyakarta State University (YSU). This study was conducted based on the existingprimary and secondary data. The data analysis to get the rainfall intensity was conducted usingthe analytical method that obtain the values of the standard deviation, the mean, the coefficientof variation, the asymmetry and kurtosis. From these values, it was obtained the types ofeligible distribution after going through the test to get the maximum rainfall in the period of 2years, 5 years, 10 years, 20 years and 25 years. Based on the data, the arch intensity wasexamined. The analysis showed if20% of YSU area is occupied by infiltration wells or if thereare 250 infiltration wells in which 1 infiltration well is used for the area of 350 m2, the need ofinfiltration wells will be covered and it is going to reduce the flow rate of the runoff in 0.552 m3/s.This is consistent with the concept of sustainable rainwater drainage system based on theconservation of ground Water. Essentially,it is a drainage system in which the rainwater fallingon the roof/pavement, is accommodated in a system of water absorption among othersinfiltration Wells therefore it will reduce the the floodwater runoff at the Colombo street. Anotherbenefit isthe infiltration wells will also increase the ground water level.Keywords: Rate of Flow, Infiltration Well, Rain Water
