Abstract

Pile foundation serves to distribute all the loads in the building to the ground. There are several calculation methods for bearing capacity of pile foundation, one of them is Nakazawa method. Nakazawa method adapted from calculation used in Japan where it is relevant for soft soils. The aim of this research is to obtain axial bearing capacity of pile foundation that can withstand axial forces using Nakazawa method. The parameter that used for the calculation is modified or average N-value (). The analysis result shows the  value is smaller than N existing, indicate that Nakazawa tend to use weaker value of N blows. It means the calculation is considered softer type of soils than the existing ones.The value of point bearing capacity, Rp, assimilate to the pattern of N-SPT. The result value of friction bearing, Rf, in respect of depth shows the linear trending. Rf along the pile depends on the friction interaction between soil and structure. This phenomena influenced by the soil type. The value of cohession along the pile augment, means the ability of soils to stick to the pile/structure is also high. It explains why the value of friction bearing is bigger in respect of depth.

Abstract

Kegiatan tri dharma yang dijalankan oleh perguruan tinggi, dalam bentuk pengabdian kepada masyarakat adalah kegiatan civitas akademika yang memanfaatkan ilmu pengetahuan dan teknologi untuk mencerdaskan kehidupan bangsa dan memajukan kesejahteraan masyarakat. (Direktorat Riset dan Pengabdian Masyarakat, 2018) Kegiatan pengabdian yang diadakan di tengah kondisi pandemi COVID 19 saat ini, memaksa perguruan tinggi mengadakannya sesuai dengan protokol kesehatan yang diterapkan dengan protokol Kesehatan dengan ketat. Kegiatan Pengabdian Masyarakat ini diadakan oleh Jurusan Teknik Sipil – Institut Teknologi Adhi Tama Surabaya (ITATS) bekerja sama dengan RW 02 Kecamatan Kertajaya Kecamatan Gubeng Kota surabaya mengambil Topik "Sosialisasi Mitigasi Bencana di Lingkungan RW 02 Kelurahan Kertajaya Kecamatan Gubeng Kota surabaya”. Hasil dari pelaksanaan pengabdian masyarakat yang dilakukan di balai RW dengan kegiatan sosialisasi Mitigasi Bencana anak – anak bisa menerima edukasi atau ilmu yang diberikan jika terjadi potensi Bencana alam seperti banjir, gempa bumi dan ada pula bencana yang disebabkan kelalaian manusia seperti kebakaran dan diharapkan anak – anak bisa mempraktekkan jika terjadi bencana dan bisa melindungi keluarga, serta masyarakat sekitarnya. Banyak masyarakat yang kurang mengetahui cara mengantisipasi jika terjadi bencana. Maka dari itu kami sebagai mahasiswa dan para dosen memberikan edukasi bencana yang sangat perlu dilakukan sebagai pembelajaran dan perkenalan awal pada Mitigasi Bencana diharapkan dengan sosialisasi ini para warga RW 02 dapat menambah wawasan dalam menghadapi bencana dan mengetahui Tindakan awal yang harus dilakukan saat evakuasi jika terjadi bencana.
