Abstract

Guru Penggerak sebagai salah satu komponen utama dalam Program Sekolah Penggerak dalam hal ini agar dapat memaksimalkan perannya, haruslah ditunjang dengan kompetensi yang dibutuhkan. Dalam kegiatan pengabdian masyarakat ini, objek difokuskan pada Guru untuk jenjang Pendidikan Anak Usia Dini (PAUD). Kondisi nyata menunjukkan bahwa Guru PAUD memiliki variasi yang beragam secara kualifikasi maupun kompetensi. Di sisi lain, Program Sekolah Penggerak menuntut adanya SDM yang kompeten untuk mengimplementasikan pembelajaran paradigma baru berbasis berbagai digital platform dengan tujuan untuk mengurangi kompleksitas, meningkatkan efisiensi, menambah inspirasi, dan pendekatan yang customized. Berkaca pada kebutuhan dan kondisi yang ada, maka diperlukan pelatihan dan pendampingan bagi Guru PAUD utamanya dalam Kompetensi Teknologi Infomasi dan Komunikasi (TIK). Pada laporan ini disampaikan pelaksanaan kegiatan pengabdian masyarakat yang berjudul “Peningkatan Kompetensi Teknologi Informasi bagi Guru Sekolah Penggerak untuk mendukung Pengembangan Pendidikan Daerah secara Berkelanjutan”, dengan lokasi kajian Desa Jombok, Kecamatan Ngoro, Kabupaten Jombang, Jawa Timur. Kegiatan utama dan penyiapan luaran dilaksanakan pada rentang waktu bulan Mei hingga September 2023.

Abstract

Slamming is a phenomenon that occurs on floating structures. Drillship as floating structures have slamming when moving at a certain speed which resulted in the movement of relative vertical bow that exceeded full of water of the bow. This paper was performed on the drillship 35000 tons with variants of speed is 7 knots, 12 knots, 13 knots and 14 knots. The first stage taken was the design of the drillship structures by using Maxsurf in order to get lines plan. After the offset data of drillship has been obtained, modeling followed by Hydrostar to get the heave and pitch motion RAO’s from head seas. The result of RAO is used to analyze the relative vertical motion of the bow in the form of RAO as well. That result is used to analysis of structural response by multiplying the wave spectra ITTC/ISSC. From these calculations will be known slamming parameters that can generate the probabilities, intensity and pressure of slamming on the drillship 35000 tons. Probabilities, intensities and pressure of slamming, the maximum occures while the drillship moving on 14 knot of speed, ie. each of 0.483 times, 124.451 times/hour and 492,232 kPa at 15 m of significant wave height.

Abstract

Offshore platform is a structure that serves as a well drilling facility to explore, extract, store and process petroleum and gas located under the seabed. There are several phases in theconstruction of offshore structures (fixed jacket platform) from preparation to construction. Fabrication phase is the earliest stage in the manufacture of a fixed offshore platform (jacketstructure) which is carried out by the fabricator. One of the procedures at the fabrication phase is roll up procedure. In this final project research, an analysis will be carried out regarding the configuration of the rigging, crane, and sadle support used in the jacket structure during roll up procedure. After the analysis of jacket structure modeling using the SACS software, the results of rigging configuration can be obtained, which were the slingsspesifications used to connect the structure with cranes, with sling diameter of 2.75 inch and SWL value of 64 MT. As for the sling used to connect the jacket with winch has a diameter of 1.5 inch snd SWL value of 18 MT. Furthermore, the cranes used have a capacity of 75 and 78 MT, respectively. In the load analysis of the jacket structure, it was found that saddle support received the largest reaction when the jacket was at an 80-degree slope with the largest reaction value of 102.74 MT. In the saddle support local analysis, the result of maximum equivalent von-mises stress obtained was 43,486 MPa, with the saddle allowable stress of 345 Mpa, therefore the UC value of 0.24 can be obtained.

Abstract

Lifting is one method in the loadout process. Lifting is the activity of moving a structure using the help of a crane. The loadout process moves the structure from the yard to the barge. In this study, a lifting analysis was carried out on the topside offloading platform structure. The analysis also considers the center of gravity shift factor, dynamic load factor (DAF), and other safety factors that occur in the structure during the lifting process. Dynamic load factor using Dynamic Amplification Factor. Cog shift during lifting affects the amount of load being lifted. The most significant load received by the lifting point is 872.507 kN at lifting point 3. During the lifting process, no failure was found in the structural members, as evidenced by the maximum UC value of 0.87. The Padeye used is designed according to the DNV OS-H205 criteria. Several checks on the padeye structure were carried out, comparing the stress that occurred with the allowable stress on several stress reviews, such as tensile stress, shear stress, and bending stress. Local analysis was also carried out on the padeye structure to determine the stress on the padeye structure. Local analysis of the padeye structure was conducted using the ANSYS Workbench software. The results of the regional analysis showed the equivalent von-mises of 164.96 MPa in the padeye structure and 140.04 MPa at the joints, with the allowable stress of ASTM A36 steel material of 250 MPa.
