"PENYELIDIKAN STRUKTUR DAN KARAKTERISTIK TANAH UNTUK DESAIN PONDASIIRADIATOR GAMMA KAPASITAS 2 MCi. Penyelidikan tanah telah dilakukan sebelum pekerjaandisain struktur pondasi gedung iradiator. Pengambilan sample ditetapkan di beberapa titik bor di sitefasilitas Iradiator pada lapisan tanah terganggu maupun tidak terganggu. Dari hasil penyelidikantanah ini akan dipilih alternatif / jenis, kedalaman serta dimensi pondasi yang paling ekonomis tetapimasih aman. Metode penyelidikan tanah yang digunakan adalah Deep Boring, Undisturbed danDisturbed Sampling, SPT (Standar Penetration Test), CPT (Cone PenetrationTest/Sondir). Pengetesan dilakukan di lapangan dan di laboratorium mekanika tanah untukmengetahui sifat mekanik, ketebalan lapisan tanah dan sifat-sifat fisis lainnya guna perhitungan dayadukung pondasi. Hasil penyelidikan tanah di tiga titik bor didapatkan hasil rata-rata kedalaman tanahkeras -19,33 m dan daya lekat 3163,88 kg/cm?. Uji boring pada salah satu titik ditemukan lapisantanah keras pada kedalaman 32 m dengan nilai SPT maksimal 16. Maka dari data dapat ditentukanjenis pondasi yang sesuai adalah bored pile. Dikarenakan pondasi merupakan penopang strukturatas yang dapat mengakibatkan penurunan/ settlement jika daya dukungnya tidak mampu menahanbeban di atasnya.INVESTIGATION OF STRUCTURE AND CHARACTERISTICS OF SOIL FOR FOUNDATIONDESIGN OF GAMMA IRRADIATORS CAPACITY 2 MCi. Soil investigation conducted before thework of irradiator building structural foundation design is initiated. Intake of sample was set at somepoint drill at Iradiator facility site to the disturbed soil layer or not disturbed. From the results of thissoil investigation will be selected as alternative / types, the depth and dimensions of the foundationof the most economical but still safe. Soil investigation method used was Deep Boring, undisturbedand disturbed sampling, SPT ( Standard Penetration Test ), CPT ( Cone Penetration Test / Sondir ).Testing conducted in the field and in the laboratory of soil mechanics to determine the mechanicalproperties, soil layer thickness and other physical properties for calculation of the bearing capacityof the foundation. The results of the soil investigation at the three-point drill showed the averagedepth of the bedrock -19.33 m and adhesion 3163.88 kg / cm?. Test boring at point BH1 found thebedrock at a depth of 32 m with a maximum SPT value 16. from the data can be determined theappropriate type of foundation is bored pile. The foundation is the upper structure support which canlead to a reduction / settlement if its bearing capacity is not able to withstand the load on it."

"Skripsi ini membahas perbandingan permodelan piled-raft 3D dalam tesis An Wang Three Dimensional Finite Element Analysis of Pile Groups and Piled-Rafts dengan model piled-raft 2D yang dibuat dengan SAP2000 10. Ini dilakukan dengan penyederhanakan model tiang dan tanah menjadi spring. Output SAP2000 10 berupa displacement maksimum, differential settlement, bending moment, dan distribusi beban dianalisis balik ke model An Wang. Hasil penelitian membuktikan model SAP2000 10 tidak mampu menandingi keakuratan model An Wang secara kuantitatif namun secara kualitatif memiliki sifat yang sama.

This essay discusses the comparison between piled-raft 3D modeling in An Wang's thesis 'Three Dimensional Finite Element Analysis of Pile Groups and Piled-Rafts' with piled-raft 2D modeling made with SAP2000 10. This is done by simplification the pile and soil into spring. SAP2000 10 output shows maximum displacement, differential settlement, bending moment, and load distribution which is analyzed back to the An Wang. Results of research prove SAP2000 10 model can't match the accuracy of the An Wang model quantitatively but its nature is same qualitatively."

"Skripsi ini membahas perubahan-perubahan peraturan gaya gempa dari SNI 03-1726-1989 menjadi SNI 03-1726-2002. Perubahan peraturan tersebut diaplikasikan ke dalam perhitungan untuk bangunan 10 lantai di daerah Ancol dan Depok. Kemudian hasil perhitungan dipakai untuk mendesain pondasi tiang pancang menurut jenis tanah masing-masing daerah. Desain pondasi tiang pancang tersebut direncanakan biaya konstruksinya, dari hasil tersebut bisa diketahui seberapa besar perbedaan peraturan gaya gempa tersebut dalam desain dan biaya konstruksi pondasi tiang pancang dilihat dari jenis tanah masing-masing daerah.

This final assignment discusses of changes in seismic building codes SNI 03-1726-1989 to SNI 03-1726-2002. Changes in seismic building codes applied to the calculation for the 10 floor building in Ancol and Depok. Then the results of calculations used to design the foundation piling according to soil type in each region. Pile foundation design is planned construction costs, the results could be known how much difference seismic building codes in the design and construction cost of the foundation piles of soil types seen in each region."
