Peluang diterima sebagai Mahasiswa Universitas Indonesia alias UI

Image
Jadi gini, emak gua nyuruh adek gua pas kuliah jangan di jogja, ngikut gua aja di jakarta.. -____- dan iseng iseng aja gua buka web nya UI meski gua agak kurang yakin adek gua bisa sanggup masuk UI.. dan gua ngira ngira kira kira peluang masuk UI tu saingannya banyak apa kagag.. :v Sebenrnya judul di atas terlalu lebay,, gua gak nemu berapa persentase atau peluang lo bisa keterima di UI karena data yang dua dapet dari http://www.ui.ac.id/id/profile/page/facts/staf-dan-mahasiswa itu menurut gua sih gak cukup jelas... Ini gua cuma menginterpretasikan sambil sok sok tau aja dari data yang gua dapet, dengan sedikit logika gua yang kadang kadang bener meski lebih sering salah.. at least gua udah nyoba.. Dari website yang gua sebut di atas, cuma ada data persentase penerimaan tiap fakultas dari total penerimaan taun itu. Tapi sama sekali gak ada data jumlah mahasiswa tiap fakultas yang di terima tiap taunnya... simpel aja men, gua anggap ruang kuliahnya tetep dan kursi kuliahnya ...

The most important thing in designing foundation of tower crane using pile group

Hey there.. what s up?? haha.. it s not a bad day is it? but next several day going to be bad day for me.. haha.. lemme tell you something, u know  that I just a graduated last 4 mounth ago, and now in my work, my boss just asked me to design the foundation of tower crane. Fistly I design it and use raft foundation,, a very big foot plate about 5 x 5 m and 1,5 m of thicknes. I m enough confidence for it,, but u know what? he asked me to change it using pile group.. because it s cheaper than the raft. It reduce your volume of concrete, and so do the main rebar Then I just design it with the deep foundation formula,, calculating maksimum P for single pile from NSPT test, analizing forces and moment at the pilecap and design the dimension and the rebar. the results is 3 x 3 m and 1,5 of thickes with adding 4 square pile (45 x 45 cm) with 20 m depth. Then the drafters draw shop drawings of the foundation which I ve designed. It showed the detail between the pile and the pi...

Vibration and Noise Analysis due to Diesel Hammer Pile Driving

heyyyooooo whats up,, here i ll post about the tittle above, hahaha. As a contractor, sometimes we trapped by regional regulation of using diesel or hydraulic hammer for pilling, because of its noise and vibration can damage the building or environtment around the project area. Here i ll give to u simplification of the noise and vibration analysis for airport project with unknown soil profile and type. i use refference from NH Pile hammer spec and Swedish Standard for allowable/guidance vibration (ppv) Just check it,, and comment :) ========================================================================== Approximation distance of using diesel hammer piller from existing building = 200 m Noise Due To Diesel Hammer Piller Refference : NH Pile Hammer Spesification -           Typical sound level data at 30 m from the hammer : NH series pile hammer       : 75-90 db(A) Diesel pile hammer   ...
