One of the activities of mitigation the earthquake is detect of damage andestimate the probability of building material losses because of earthquake in each typical building on an area. In the developed countries attempt to predict the probability of damage to the building caused by the quake has been a lot done. One method used is HAZUS Method (Hazard United States). In evaluating the damage to buildings, one method is used assessing HAZUS level the probability of damage to each building. This study is an initial study to compare building in Bantul-Indonesia and United State Of America.The Data collected includes the characteristic of houses. Conclusion obtainedfrom this research is that house in bantul different with HAZUS type of building.

This research study about usage of expanded polysterene for wall structure with strengthening of net wire. Styrofoam has very light weight unit which is about 13 kg/m3 up to 15 kg/m3. Lightweight concrete from expanded polysterene is an effort of utilising it as an alternative in the structure of lightweight walls. In this research, used 12 specimens of lightweight walls which were sandwich wall reference (DSK.H1-H6) has core dimension 80mm and sandwich wall polyprophyelene fiber (DS.I1-I6) with variation 0.5kg/m3; 1.0kg/m3, 1.5kg/m3 respectively. It has core 70mm, 80mm, 90mm in dimension. The dimension of lightweight wall were ±530, 400 and 120mm. Every variant consists of 2 wall, the type of load applied were compression, tensile and flexure. The data then analyzed with quantitative descriptive method. The test result showed that the average of compressive strength and tensile splitting test of self compacting mortar using fibres 0kg/m3, 0.5kg/m3, 1.0kg/m3, 1.5kg/m3 which were 12,45MPa, 10.38MPa, 12.24MPa, 9.49MPa and were 1.54MPa, 1.28MPa, 1.41MPa and 1.08MPa respectively. The addition of polypropylene fiberswere not influence compared with reference cylinder with 0kg/m3 fibers.The composition of the addition of polypropylene fiber will optimum of 1,0kg/m3 in volume. The core and plastering effective were the results 80mm and 20 mm, that the dimensions can increase the capacity of load 6.92%. The value of the maximum load capacity of walls on sandwich styrofoam is of 22.86kN on the addition of polypropylene fibers 1.0kg/m3 in volume.

This research study is determine the influence of the addition of bagasse fibers based on quality of plasterboard, which include: the absorption of water, the density of water, the ability of nailed, and flexural strength. This research was carried out in the Laboratory of building materials of YSU and Laboratory Of Structures GMU. The specimens for each composition consist of five pieces. The research method using experiment approach, the data then analyzed with compare the test result and SII.0016-72. The mix of bagasse fibers were 1sp:3kp:1st, 1sp:3kp:2st, 1sp:3kp:3st, 1sp:3kp:4st, and 1sp:3kp:5st respectively. Water absorption test results using the milling of bagasse fibers manual, the weight of content, and flexural strength for the composition 1sp:3kp:1st, 1sp:3kp:2st, 1sp:3kp:3st, 1sp:3kp:4st, and 1sp:3kp:5st the result were 21.95%, 18.68%, 21.80%,24.87%, 23.96%; 2.24gr/cm3, 2.15gr/cm3, 2.16gr/cm3, 1.18gr/cm3, 1.8gr/cm3 and 45.65kg/m², 47.34kg/m2, 91.73kg/m2, 26.74kg/m2 and 36.4kg/m2, respectively. The water density and visual test results for composition I, II, and III are good, whereas for composition III and IV occurring droplets. The capability test nailed does not occur crack on all composition. The water absorption, weight of content and flexural strength test results using the milling of bagasse fibers for mixed composition 1sp:3kp:2st, 1sp:3kp:3st, and 1sp:3kp:4st were 8.35%, 11.35%, 15.44%; 2.92gr/cm3, 2.73 gr/cm3, 2.41 gr/cm3 and 51.37kg/m2, 101.66kg/m2 and 73.93kg/m2 respectively. The density of water with co mposition 1sp:3kp: 2st, and 1sp: 3kp: 3st does not occur while the droplets to composition 1sp: 3kp: 4st. The capability test nailed does not occur crack on all composition, it is of the best qualified based on SII. 0016-72 is 1sp: 3kp: 3st with bagasse fiber.

Stabilitas adalah salah satu pertimbangan utama dalam perencanaan struktur gedung. Begitu banyak kegagalan struktur yang diakibatkan oleh persoalan stabilitas, terutama pada komponen struktur yang menerima beban aksial. Berdasarkan teori dan praktek, jenis tumpuan yang berbeda akan memberikan pola tekuk yang berbeda juga. Perbedaan ini akan berakibat kesalahan dalam analisa beban kritis yang dengan sendirinya menjadi tidak akurat lagi. Pertimbangan keakuratan dan ketepatan dalamprediksi beban kritis ini maka telah banyak perangkat lunak dari analisa struktur yang telah dikembangkan, khususnya analisa tekuk dan SAP2000 adalah salah satunya. Penelitian ini berfokus pada kajian numerik yang berdasarkan pada metode elemen hingga dari sebuah batang aksial tekan yang mempertimbangkan kelangsingan untuk mendeskripsikan kegagalan tekuk. Model pengujian diperoleh dari salah satu sampel penelitian oleh Miftah (2010) yang menggunakan galvanized pipesebagai batang tekan yang dimodelkan sebagai circular hollow section , CHS. Selanjutnya dengan bantuan SAP2000 versi 11,00 akan dibuat pendekatan batang tersebut dengan model frame 3D dan model shell 3D dengan menambahkan spherical dome shell pada ujung-ujung model tersebut untuk kemudan dilakukan analisis dengan analisa statik untuk tekuk linear. Akhirnya kedua model tersebut dibandingkan dan kemudian dari keduanya akan dilakukan verifikasi terhadap nilai eksak (Euler analisis) dan hasil uji eksperimen. Hasil penelitian menunjukkan bahwa dengan melakukan penambahan spherical dome pada ujung-ujung cylindrical shell model akan membuat beba n aksial terkosentrasi pada tumpuan dalam hal ini meggunakan tumpuan sederhana sehingga akan memberikan pola tekuk yang serupa dengan model Euler satu dimensi. SAP2000 versi 11 memberikan ketelitian yang sangat tinggi terhadap hasil analitik yaitu 0,028%. Selain itu, dari kombinasi spherical dome-cylindrical shell pada SAP2000 versi 11,00 juga memberikan ketelitian yang cukup baik yaitu -5,47% dan menunjukkan bahwa dengan model ini beban kritis yang dicapai jauh lebih konservatif dibandingkan dengan menggunakan model frame 3D. Penelitian ini juga menjelaskan bahwa modulus elastisitas meberikan pengaruh yang sangat signifikan terhadap kesesuaian nilai numeric dan eksperimental yang secara berturut-turut diberikan sebagai berikut 27,76%;35,37%;72,06%

The dam is always identified as the shelter of water (water storage) which is used to satisfy the needs of human life. However, the dam holds in its development can also be used for agricultural irrigation systems in line with the development of agriculture. Up to this point, the dam holds still utilized in accordance with the basic concept that for the purposes of everyday, the need for agriculture (irrigation), energy (electricity), flood control, and so on. Then for ease in learning and understanding the characteristics of a dam holds then created a model that approximates the actual dam holds that aims to be able to better understand the symptoms that occur at a dam holds. The purpose of this research is to be able to create a system interface and information systems that can support a model dam holds motion. The resulting Model can then be used as a medium of learning technology application in the dam Hydraulics courses.Design of a system of an interface automation a model of weir motion it consists of design of hardware and software. Hardware design includes a series of sensors and driver circuit motor SRF02 stepper. Data obtained in this study was analyzed using the Chauvenette Criterion Method. This method of data are invalidate and tends to produce outlayer interpretation is not good. The test results showed that the value of the resulting data transducer SRF02, the equation of y = -0.698x + 8.2062 with coefficients of correlation value 0.9705. This shows that the transducer used to have a good liniear equation of high water on the overflow that is measurable.The test showed that the stepper motor has been able to move in accordance with orders. From the test results can be seen that the software has been created can be run and hardware are made to work according to have commands that are present in the software. So it can be inferred that the system that has been created can work well.
