Abstract

In general the measurement of land area can be used several simple tools. While for the measurement an accurate of land area then required a tools measurement namely theodolit. The resulting data from the measurements of theodolite which was horizontal angle, vertical angle, upper stadia, center stadia, lower stadia, and horizontal distance. There are several kinds of ways or method of determining the land area by counting broad in manner divide into several triangles, by counting coördinate, and by help program mapinfo 8.5. A method of calculating the land area by using program mapinfo 8.5 used as a reference method another in determination of the land area. To method of dividing the extent of land into several triangular obtained result is 1473,93 m2 and prosentase preciseness is 99,59 %. The method of calculating the land area by coördinate method obtained result is 1472,38 m2, and prosentase preciseness is 99,49 %. While the method of calculating the land area by using program mapinfo 8.5 obtained result is 1480 m2 with prosentase preciseness equal to 100 %.Keyword: the measurement, the land area, theodolite, program mapinfo 8.5.

Abstract

Generally, building residential or construction of buildings in indonesia using walls of masonry red both in finishing with stucco or without stucco. Aim of this study to determine the compressive strength value uses a new specie of the former specie aggregate results dismantling the wall and to determine the compressive strength value of comparison with the new specie aggregate (using natural sand aggregate Ngraho Bojonegoro). Specie siar recycle used in this study contains material was red brick, sand, red cement, lime and cement. Ingredient for all specie that used on the specimen testing using a ratio of 1 PC : 5 sand. the compressive strength value testing using a sample of a cube measuring 150 mm x 150 mm x 150 mm with 3 variations of the sample is 0% (without the former specie), 50% (with 50% of the former specie) and 100% (100% with the new specie using natural sand aggregate Ngraho Bojonegoro). the compressive strength value of Species from the recycle specie qualify as specie type O, with a minimum compressive.strength.value.is.24,5.kg/cm2.Key words : new specie, the former specie, species of siar, the compressive strength value.

Abstract

Indonesia is a country often occurring earthquakes because most of the islands of indonesia situated in regions that have the activity of the earthquake are enough high because indonsia areas located at the confluence of three main plates of the world namely indo-australia plates, eurasian and pacific. To research will be done the study analysis of the structure on the burden of building earthquake use borland delphi 6 with studies the structure of the building floors 4 which are located in the madiun with force concrete (fc) used is 25 MPa and yield strength for steel (fy) that is used is 320 MPa. The purpose of this research is to calculate the value of a shearing force the average the layer of soil, the burden of nominal basic sliding horizontally because of earthquake that work on the structure building, the distribution of the burden of high earthquake building along, time a trill fundamental natural structure, and performance service limits the structure of the building with used the results of the program design using language programming delphi 6. To analysis of the structure on the burden of earthquake used SNI 1726 2002. The results of design application program using borland delphi 6 shows that the results of the value of obtained have a value by a similar. The difference in the value of the results could happen if the data included data is the result of rounding.Keywords: Borland Delphi 6, application program, analysis of the structure, the burden of building earthquake.

Abstract

The salak road often flooded a while during the rainy season. Drainage on the salak road in the rainy season was less than optimal in accommodating some run off sparking inundation points on the road. The rainfall data used in the planning was daily maximum rainfall data for 10 years observation (2004-2013) obtained from PSAWS Madiun. A calculation and recapitulation analysis frequency of rainfall with a method of distribution logs pearson type III. A drainage debits were calculated was discharge which was stored by the duct secondary I and II to put this in terms of water runoff from all regions actuall. The size of the discharge that may be accommodated by the drainage (Q drainage) was 0,782 m 3 /s the amount of discharge flood maximum was 1,0702 m 3 /s. So that capacity secondary drainage inadequate to accommodate discharge maximum because Qdrainage < Qmaksimum. Key Words: The salak road, the rainy season, flood, drainage.
