Struktur bangunan bawah jembatan berperan sangat penting dalam komposisi suatu jembatan. Tanpa perencanaan yang baik pada struktr bangunan bawah jembatan yang meliputi kekuatan pertahanan tanah, pilar tengah, tiang pancang, maka bangunan atas tidak akan berfungsi dengan baik. Penggunaan pondasi tiang pancang harus diperhitungkan dengan teliti agar mendapatkan hasil yang maksimal. Hasil pembahasan ini meliputi daya dukung tanah yang kuat pada lokasi tersebut terdapat kedalaman 37 m, dengan nilai N-SPT 4632,65 kN dan beban yang mampu ditahan sebesar 10.572,66 kN, dengan perhitungan daya dukung tiang pancang melalui beberapa kali percobaan kombinasi susunan kelompok tiang untuk mencari tiang pancang dan diperoleh 18 tiang pancang dengan diameter 0,50 m.Kata kunci : Perencanaan, Pondasi, Tiang Pancang.

The foundation is a basic construction of a building that functions to carry away dead loads, live loads and angina loads and earthquake loads of a building to the soil layer which is at the bottom without causing excessive soil collapse. In this calculation I use the mayerhoff method and the calculation based on the results of the analysis of the carrying capacity of single and group foundations can be concluded that: 1. the results of loading analysis that occurred in the IAIN Ponorogo Sharia Faculty Building 379,198.5 kg. 2. the calculation of the sondir which is carried out by the hard soil depth reaches a depth of 5.8 meters. Calculation of pile foundation using a diameter of 40 cm with reinforced iron D16 iron spacing 125 with 5 reinforcement contents, and said SAFE. 3. The results of the shear force control calculation: a. Calculation of One-Way Shear Control = 1,085.34 tons> Nominal Shear Force = 348.05 tons said SAFE b. Calculation of Two-Way Shear Control = 1.272.45 tons> Nominal Shear Force = 877.91 tons said SAFE, 4. The pile foundation will experience cracking when there is a moment of 58,278,400 tons / m2 <150 tons / m2 maximum moment SAFE is permitted and said the decrease that will occur is 4,644 mm <360 mm, a decrease that is permitted and said SAFE. Keywords: pile foundation, meyerhoff method, fracture of pile foundation, reduction / pile foundation stability.

Implementation of multi storey building construction projects is very prone of work accidents, so the application of Occupational Safety and Health must be strictly considered. This study purposes are to determine the most dominant occupational safety and health implementation measures and the level of implementation of occupational safety and health in the Shared Lecture Building Project Of Campus C Airlangga University Surabaya. This research uses quantitative descriptive method. The research populations are 150 workers, which include: security, workers, foremen, safety officer, project implementers and management staff. The sample was determined by the slovin technique with the results of 60 respondents. Data collection by distributing questionnaires to respondents. The results of data collection were tested for validity, realibility testing and statistical frequency analysts using IBM SPSS Statistics 25 software. In this study the most dominant results of the application of Occupational Safety and Health (K3) is checking the condition of PPE and the provision of PPE that is periodically complete with a value of 91.70%. The application level of Occupational Safety and Health (K3) in the Shared Lecture Building Project Of Campus C Airlangga University Surabaya has a percentage of 77.84%, so it can be classified in the VERY GOOD category. Pelaksanaan proyek konstruksi gedung bertingkat sangat rawan akan terjadinya kecelakaan kerja, sehingga penerapan Keselamatan dan Kesehatan Kerja harus benar-benar diperhatikan. Tujuan dilakukan penelitian ini untuk mengetahui tindakan penerapan Keselamatan dan Kesehatan Kerja yang paling dominan dan tingkat penerapan Keselamatan dan Kesehatan Kerja pada proyek pembangunan Gedung Kuliah Bersama Kampus C UNAIR Surabaya. Metode penelitian ini menggunakan deskriptif kuantitatif. Populasi penelitian berjumlah 150 tenaga kerja yang meliputi: satpam, pekerja, mandor, pelaksana K3, pelaksana proyek dan staff manajemen. Sampel ditentukan dengan teknik slovin dengan hasil 60 responden. Pengumpulan data dengan membagikan kuisoner kepada responden. Hasil pengumpulan data dilakukan uji validitas, uji reliabilitas dan analis frequensi statistic menggunakan software IBM SPSS Statistic 25. Pada penelitian ini di dapatkan hasil tindakan penerapan Keselamatan dan Kesehatan Kerja (K3) yang paling dominan adalah Pengecekan Kondisi APD dan Penyediaan APD yang lengkap secara berkala dengan nilai 91,70%. Tingkat penerapan Keselamatan dan Kesehatan Kerja (K3) Pada Proyek Pembangunan Gedung Kuliah Bersama Kampus C UNAIR memiliki prosentase 77,84 %, sehingga dapat di klasifikasikan dalam kategori SANGAT BAIK.

The upper structure is the parts that make up buildings such as sloof, walls, columns, beams, and roofs. In this upper structure these components have a very important role. Today, civil engineering students are required to be able to plan well so that they are strong and durable for a long time.In planning this upper structure, of course there are many methods that can be used to calculate moments, one of them is ultimate moment method, which can be combined with a reference from SK SNI 2847,2013. For pouring images can be presented with CAD (Computer Aided Design) software called AutoCAD.The results of this plan are used for roof and floor plates used 100 mm and 120 mm thick with reinforcement used 12 mm main reinforcement and 8 mm stirrup reinforcement with a distance of 200 mm. For beams and Sloof used the same, which is 16 mm for basic reinforcement and 10 mm for reinforcement Sengkang with a distance of 200 mm. Whereas for columns, reinforcement 16 mm and Sengkang 12 mm with a distance of 200 mm are used. The load distribution that occurs is for the roof floor of 20.640,924 kgm, because the assumption of loading the 1st floor to 6th is the same, which is equal to 23.233,644 kgm. The moments that occur in this plan are on the plate occurred at 17.074,370 kgm, the beam occurred at 342.733,875 kgm and 493.536,780 kgm. In the column arises a fairly large moment, with a value of 551.697,600 kgm. From the calculation of the earthquake load get the result = 159843 (kNm).Keywords: Planning, Structure, CAD, SNI

Success of fail of project some times because of minimize planning project activity, and control is uneffectively, so the activity of project is not efficient. It has consequences later, low quality, and increasing budget of project. Project manajement must be doing from start to finish. Case studying in this researeh was bilding dormitories of Pondok Pesantren Sananul Huda. As insfrasstrukture for teaching and learning in Pondok Pesantren Sananul Huda area. The location is in Desa sumberagung, Kecamatan Selorejo, Kabupaten Blitar. PERT and CPM method used to know how long this project will be finished and found probabilities time acceleration tis project. The purpose of this research was for knowing time efficiency considered from these methods. The result of anality time manajement used PERT and CPM method, be found critical stripe as long as 102 work days. And be found optimal time with acceleration till 5 day, exactly 97 work days and increasing cost was Rp. 959.058.508;.  Keywords: Critical Part Method (CPM), Program Evaluation and Review Technique (PERT)
