Abstract

The paddy chaff is a waste of paddy hulling, and it contains dominant silica which is as big as 93 % and almost has the same contain of silica that exist on micro-silica of factory brand. With its character, if it mixed into concrete mixture, it will fix the characteristic of concrete. In this research, the ash of paddy chaff is added into the mix of normal concrete, C- 225 Kg / Cm2, with the variation of the ashes chaff 0%, 2,5%, 5%, 7,5%, and 10%, heavy of percentage of the ashes, it was taken based of the weight of cement. The effect of this research is to know the pressing strong point of concrete, is reached from the chaff ash mixture paddy in concrete k 225 kg / cm.The design of concretes used the standard of SK.SNI.T-15-1990-03 that default in Indonesia. The object of the test, that is made for each one ash of percentage increase chaff is as much 3 samples, with cylinders printed of diameter is about 15 cm and tall is about 30 cm.

Abstract

The objective of this work is to investigate the rheological performance of a locally-sourced bentonite from Sabah for use as drilling fluid against a commercial benonite from India. The rheological properties of the drilling fluids were obtained by using standard testing apparatus such as mud balance, viscometer and filter press. It was observed that the Sabah bentonite has lower values of density, gel strength (GS), plastic viscosity (PV), yield point (YP) and filtration loss as compared to the Indian bentonite. The Malaysian bentonite did not meet the API required viscometer reading of 600 rpm. However it was found that by adding 1.0 ppb of NaOH as an additive to the mud, the rheological performances of the mud improves significantly to meet the API standard. Economic analysis indicates that the treated Sabah bentonite mud is much cheaper than the Indian bentonite by as much as 61%. The results of this work showed that the locally-sourced treated bentonite is technically and economically feasible for use as drilling fluid application.

Abstract

The existence of urban public transport is part of a transportation system components kota. Kebutuhan public transport is closely related to movement patterns or distributing the trip (trip distribution) users of public transport services (passenger). Passenger travel patterns of distribution can be expressed in the form of an origin destination matrix (OD) passengers.This research was conducted to determine the movement patterns of travel (trip distribution) city passenger transport Bemo Bemo Lyn Lyn Q and N as a route microbus Terminal Bratang - JMP Surabaya which was formed in an origin destination matrix (OD) based on the observation (observation) field, Formulation deployment passenger travel is formed with Gravity Model. MAT results of modeling to compare against the MAT observations to determine the suitability of the model by holding a custom test Kolmogorov-Smirnov statistics, pair-T test, and Mann-Whitney. The results showed that the OD matrices as a form of passenger travel distribution based modeling has a compatibility with field observations based on the results of Kolmogorov-Smirnov test at significance level α = 4%.

Abstract

Solar power (SP) is a new technology that is environmentally friendly and have an unlimited source location especially Indonesia, which is at the equator is highly disadvantaged because there is sunshine all year round. It is therefore a very potential new technology is developed on a large - scale in Indonesia that is being suffered an energy crisis. Starting from the problem above, the authors raise and interested at all about Solar Power as a potential energy source is developed in Indonesia, the Batas Village Water Supply Project the use of technology Solar Power Generation.

Abstract

The purpose of this study was to determine the balance between water availabilityin particular water needs in agriculture (rice water availability) using Gambel method for rainfall, FJ method Mockforriver flow based on rain fall.For water needs using evapotranspiration values (ETo) based on climatological data including air temperature (temperature), wind speed, solar radiation and humidity old at Rambah rain fall station from 2002 to 2011. By using the method Pennmant.The results of this study demonstrate that for 50 years and then water shed Kaiti Samo still in good shape when cared for properly.

Abstract

SSK II airport in 2007 has a capacity of 1.8 million passengers per year with an area of terminal building are 6700 m2. Airport with an area of 6700 m2 should have a capacity of approximately 800 thousand to 1 million passengers per year. This means that the condition of SSK II Airport Pekanbaru is not suitable for use as this will impact on the quality of passenger service at the Sultan Sharif Kasim II airport.For that condition, analysis needs to be done to get the models arrival and departure passengers at the existing condition. The independent variables used in this study are: amount of population (X1), PDRB (X2), number of moderate and large industrial companies (X3), number of students (X4), number of lecturer (X5), export (X6), imports (X7), number of hotel rooms (X8), number of foreign tourists (X9).

Abstract

Pemukiman atau rumah tinggal dan perumahan merupakan salah satu kebutuhan dasarmanusia. Pemenuhan kebutuhan akan rumah tinggal yang sudah dilakukan belum juga dapatmenjangkau sebagian masyarakat, khususnya yang berlokasi di daerah-daerah. Walaupunmempunyai sumber material, tetapi masih belum dimanfaatkan secara optimal oleh masyarakatuntuk bahan bangunan, terutama bahan yang dibutuhkan untuk pembuatan beton. Sebagian besarbahan pembuat beton adalah bahan lokal (kecuali semen portland atau bahan tambah kimia).Selama ini baru sebatas pemanfaatan batu gamping (klastik siliklastik) untuk fondasi. Selain itudianggap sudah dapat menggantikan fungsi dari batu kali sebelumnya. Penelitian ini bertujuanuntuk mengetahui perbandingan kuat tekan beton dengan agregat pecahan batu gamping (klastiksiliklastik) dan beton dengan agregat batu alam krakal (andesit) pada umur 28 hari, mengetahuipengaruh variasi faktor air semen (fas) terhadap kelecekan beton segar dan kuat tekan beton padasetiap variasinya.

Abstract

Corrosion is a problem that always happens to the equipment of oil and gas production. Pipe production is one piece of equipment that will not be separated from the process of corrosion. Long Range Ultrasonic Testing is one method that can be used to detect the onset of corrosion in the production pipeline. The method makes use of ultrasonic waves as a medium in the complete evaluation by teletest unit as system settings. In the test series in the field of production pipe Arzon # 89 the corrosion rate will be obtained when the magnitude of the reduction is calculated first pipe wall thickness (wall loss) of yield teletest data reporting system.
