Studi Perbandingan Kinerja Sistem Struktur Setback berdasarkan Metode ATC 40, FEMA 356 dan SNI 1726:2012

The aim of this study was to compare the performance level of the setback structure system and the non-setback structural system using the ATC-40, FEMA 356 and SNI 1726-2012 methods. The non-setback structure have the shortest span of 15 m, the longest span of 20 m and the level of each floor was 3.5 m but the setback structure have setback system on the longest span of 10 m at the 5th and 6th floor level. The results showed that the performance level based on all methods of the sectback structure system is at the immediate occupancy level while the non-setback structure system, based on SNI 1726-2012, the performance level is immediate occupancy for the longest span and the shortest span is damage control. On the other hand, based on the ATC-40 and FEMA 356 methods, the performance level of the non-setback structure is at the immediate occupancy level. Drift on non-setback buildings based on the SNI 1726-2012 method is 0.011, based on the ATC-40 method is 0.007, and based on FEMA 356 is 0.005. Drift on the setback building based on the SNI 1726-2012 method is 0.010, based on the ATC-40 method is 0.006, and based on FEMA 356 is 0.004

Penggunaan Gypsum Block Untuk Mengukur Kadar Air Pada Tanah Lempung

The test of soil moisture content that most often method applied is gravimetric. By the development of sciences, nowdays a sensor device test on soil moisture content that is called gypsum block. Such devices could be directed inplanted in the place where the moisture content would be measured. This research aimed at getting the calibration equation and correlation coefficient of gypsum block and to determine whethergypsum block could be used as a test of moisture content of clay. The kind of sample was taken from Oebelo village, Central Kupang Subdistrict, East Nusa Tenggara and variations of water used were 15%, 20%, 30.7% and 40%, and total samples were 20. The results of the research revealed that calibration equation of gypsum block to the measurements for 7 days (constant resistantion) was Y=1.323x-0.54 by r = 0.835. The results of field testing and compared with gravimetric method obtained difference moisture content value in the range of 0.26%-2.56%. From the results it could be concluded that the gypsum block could be used as a device to measure the moisture content of clay

Wood are used for meet human needs as a construction material. The utilization of wood impact to deforestation and environmental damage. Therefore, it needed another alternative construction materials instead of wood. This research aims to know the compressive strength and bending strength of the alternate materials of wood with variations mixture of nylon fibers. This research was conducted by an experimental method that used 4 mixtures of variation, namely: mixtures of nylon fiber 5%, 10%, 15% and 20% with the ratio mixture is: 1 cement : 0.25 pulp 1.25 water. Compressive strength testing was made 12 sampels with size 200 mm x 50 mm x mm. The sampels used in the bending test are 12 sampels with a size 200 mm x 50 mm x mm. From the research and analysis of data obtained by the compressive strength and bending strength testing of the mixture into four is as follows: for the compressive strength test results of the alternate material of with with mixture of nylon fiber 5%, 10%, 15% and 20% was 4.58 MPa, 5.33 MPa, 6.90 MPa and 7.07 MPa.

East Nusa Tenggara province is a region abundant with pumice content. Pumice is a frothy lava composed of compacted glass pyroclastic with very mikrovesikular wall extrusive igneous volcanoes bubbling, very thin and translucent and that is a common product of volcanic eruption and the general shape of the zones of the upper silicate lava They uses of pumice, among others: metal , raw material, lightweight brick, paint, plaster material, ceramics, sand paper raw materials and much more, pumice stone contain silica so that it can be used as a subtitude filler in asphalt mixture. This research was conducted to determine the effect of using pumice stone ash as a substitute filler in asphalt mixture. It will be seen from the value of stability and flow by using Marshall. There are several steps in Marshall\u27s method need to be done include: testing gravity, aggregate gradation planning, aggregate composition plane, aggregate bulk density calculation, the maximum mixture specific test and the calculations of the parameter values in Marshall\u27s method. The results of these research are finding higher levels of filler in asphalt mixture, the higher value of the stability while the value of flow decreases with increasing value of filler content in the asphalt mixture. Based on test results, the value of the variation of filler that meets spesifications Marshall\u27s is 1% and 2%, as only two variations of these filler levels that meet all of parameter value Marshall

Pemanfaatan Sumur Resapan Untuk Meminimalisir Genangan Di Sekitar Jalan Cak Doko

Penelitian ini bertujuan untuk mencari debit banjir setiap rumah dan debit yang akan ditampung oleh sumur resapan pada rumah-rumah di Kelurahan Oetete sekitar SMA N 1 Kupang, untuk meminimalisir genangan yang terjadi di jalan depan SMA N 1 Kupang. Dalam penelitian ini menggunakan data curah hujan 20 tahun terakhir dari stasiun curah hujan Lasiana, perhitungan debit banjir rencana mengunakan metode Log Perarson Tipe III dan Metode Gumble Tipe I. Sampel tanah pada lokasi studi diambil untuk uji permeabilitas di laboratorium. Berdasarkan pengujian tersebut diperoleh koefisien permeabilitas tanah (k) adalah 6,01x10-5 cm/detik. Sebagai contoh untuk rumah dengan tipe 8x10 memiliki diameter sumur resapan 1 meter dengan kedalaman sumur 3,3824 ≈ 3,5 m dan debit masukan 0,0007 m3/detik. Debit banjir yang terjadi pada rumah tipe 8x10 adalah 0,0014 m3/detik, setelah ada sumur resapan berkurang menjadi 0,0007 m3/detik, sehingga tereduksi banjir sebesar 50%. Hasil perhitungan diperoleh 25 buah sumur resapan dengan kedalaman bervariasi yaitu 1,5 m (4 buah); 2 m (3 buah); 2,5 m (4 buah); 3m (4 buah) untuk sumur resapan tunggal karena kedalaman sumur resapan ≤ 3 m dan kedalaman 3,5 m (2 buah); 4 m (2 buah); 6,5 m (1 buah); 9 m (1 buah); 9,5 m (3 buah) dan 21 m (1 buah) untuk sumur resapan paralel karena dari hasil perhitungan diperoleh kedalaman sumur resapan > 3m. Untuk sumur resapan paralel akan dibangun kedalaman mulai dari 1 m – 3 m sampai kedalaman sumur tepenuhi

Perbandingan Pengukuran Kadar Air Tanah Lempung Menggunakan Metode Gravimetry Dan Metode Gypsum Block Berdasarkan Variasi Kedalaman

Soil is one of the most important things in every civil engineering construction. But the problem is how to define physical and mechanic characteristic of the soil. Physical and mechanic characteristic that have influence on bearing capacity of the soil is water content. Size of soil also has effects on the changing of water content. To define water content, engineer is often using Gravimetry Method, but this method can only be doing in laboratory, so it can't specifically describe real condition of water content in the fields. Then, an in-site test such as Electrical Sensory Method is needed, in order To get correct result of water content in fields. In Electrical Sensory Method there is one method called Gypsum Block Method, this method is an in-situ water content test with individual calibration on laboratory.The results from Oebelo Village, Kupang District soils sample, the soils is CH soil, where CH is organic clay with high plasticity, Fat Clay. By using gypsum block method, water content results is in range of 19,35 % - 41,05 %, while with gravimetry method the water content is in range of 18,34 % - 34, 67 %. Water content test using gypsum block method can only be doing at 0,50 m dan 1,00 m depth range, at 1,50 m dan 2,00 m depth range cannot be using this method because is too difficult to install gypsum block and the gap results between gravimetry method and gypsum block method is in range of 4,19 % - 7,69 %
