Abstract

Sebagian besar mata pencaharian masyarakat Nambangan Perak, Kelurahan Kedung Cowek, Kecamatan Bulak, Kota Surabaya adalah sebagai nelayan tradisional dan pedagang ikan. Namun, pada tahun 2022 bulan September terdapat seorang nelayan yang hilang saat mencari ikan di perairan laut Nambangan Perak. Kasus hilangnya nelayan tersebut mendorong Tim Pengabdian Masyarakat Teknik Kelautan FTK ITS untuk membuat suatu kegiatan berupa pencerdasan/ sosialisasi guna meningkatkan pemahaman bidang K3 (Keselamatan dan Kesehatan Kerja) di masyarakat Nambangan Perak. Kegiatan pengabdian kepada masyarakat yang dilaksanakan oleh Tim Abmas Teknik Kelautan FTK ITS terbagi menjadi dua rangkaian kegiatan. Kegiatan pertama dilaksanakan di SMAN 6 Surabaya dengan tujuan untuk meningkatkan pemahaman dan pengelolaan potensi sumber daya kelautan di kalangan siswa dan kegiatan kedua dilaksanakan di Nambangan Perak Surabaya sebagai bentuk edukasi kepada nelayan tradisional tentang keselamatan dan kesehatan kerja (K3), kewaspadaan nelayan dan pengembangan sumber daya manusia. Tujuan dilaksanakannya kegiatan pengabdian masyarakat ini adalah untuk mengedukasi siswa SMA melalui aktivitas pencerdasan sehingga siswa sekolah semakin menyadari pentingnya potensi bidang maritim untuk kemajuan dan kesejahteraan masyarakat Indonesia.

Abstract

The abstract A fabrication company plans to undertake the construction of a topside structure with a weight exceeding 19,000 tons. Based on the Soil Investigation Report, it was found that the foundation in the fabrication area was previously used for the construction of a structure weighing 17,500 tons. Based on the consideration of the weight of the structure, it is necessary to review whether the fabrication area is capable of carrying out the construction of the topside structure until loadout. During the analysis process, it was found that the soil bearing capacity of the fabrication yard was 6108.99 MT at row support A1, while the minimum soil bearing capacity during the fabrication to loadout process at row support A1 was 6776.08 MT. Thus, it is necessary to modify the loadout area. In the process of assessing the strength of the soil foundation against structural loads, a support planning model is also made that will be used to support the topside structure during the fabrication process and also in carrying out loadout. The suitability of the structure and support will affect the process of assessing the strength of the soil foundation in parsing the potential for failure. In the process of analyzing the topside structure and support, under settlement conditions in the fabrication stage, it was found that there was a member that experienced a high enough stress with a UC value of 0.984 in member 2807-2808 on the deck leg above the row support. This occurred because during the settlement condition, there was a shift in the weight point of the structure with a joint reaction value of 4246.72 MT at the row support. During the analysis process on the bearing capacity of the foundation, topside structure, and support structure, the percentage of structural failure before modification of the loadout area is 2.12%, which is included in the failure category because it has a value above 1%.
