Abstract

In the case of assembly wellhead, a spacer spools was used to provide space and connect between parts of the wellhead. In order to design spacer spool with specified material should comply the standards and procedures of the oil and gas industry. The results of the material calculation were using the ASME BPVC guidelines. These three materials strengths were calculated if used as a body spacer spool. Based on acceptance criteria on API 6A 21st Edition, these three materials were categorized as acceptable to be used as a body spacer spool for this specification. These three materials strengths were also calculated the stress of the flange and flange rigidity criteria. Based on the acceptance criteria on ASME BPVC guidelines, the results showed that these materials can be used for flange because it had stress value under yield strength of material which was flange rigidity criteria for operating condition has 0.59 and 0.66 for testing condition because had value of rigidity that met with minimum acceptance criteria.

Abstract

The low demand for vocational education graduates has led to high unemployment. The low demand for vocational education graduates has led to high unemployment. Vocational college graduates still need to be commensurate with industrial needs. Many Senior High School, Vocational High School, and Vocational College graduates have not been able to find a job for more than six months. Conditions on Madura island worsened this, and the lack of accelerated industrialization even after the Suramadu Bridge was built. Madura has the lowest Human Development Index (HDI) score in East Java. Data from the Central Bureau of Statistics (BPS) Sampang in Figures 2021) shows that the HDI value in 2020 only increased by 0.76 from 2019 of 62.70. Politeknik Negeri Madura (Poltera) together with PT. United Tractors and LSP ABI want to take an active role in improving Madura's HDI by preparing human resources on heavy equipment mechanics through the development of a centre of excellence for technology (PUT) of Heavy Equipment (CHE). Using the causal-comparative method, the researcher observed the impact of each stage on PUT-CHE development activities and reviewed the data to find causal factors and correlations. Poltera took a strategic step by equipping lecturers with virtual training on heavy equipment mechanics (SOBAT Program), organized by PT United Tractors. The SOBAT program has positively impacted heavy equipment engineering graduates in 2022, which has increased significantly. Academic data showed that 13 out of 34 heavy equipment mechanical engineering graduates were employed in leading heavy equipment industries before three months. Other data stated that three lecturers participating in Virtual Training on heavy equipment mechanics were selected as 50 interns at PT United Tractors.

Abstract

Engine trainer merupakan alat bantu untuk menopang suatu mesin tertentu agar memudahkan operator dalam melakukan pekerjaan perawatan. Jurusan Teknik Mesin Alat Berat di Politeknik Negeri Madura dalam kegiatan belajar mengajarnya juga melakukan kegiatan perawatan. Adanya alat bantu engine trainer tentunya mempermudah mahasiswa dan dosen dalam mengakses bagian-bagian mesin. Pembuatan rangka engine trainer tentunya harus kokoh untuk dapat menopang mesin Mitsubishi Canter 110PS yang bobotnya mencapai 400 kg. Sambungan yang digunakan dalam penelitian ini adalah sambungan las. Metode pengelasan yang digunakan adalah metode las SMAW. Analisis pengaruh variasi arus dan electroda dilakukan dalam penelitian ini untuk mengetahui kekuatan pengelasan dan cacat permukaan yang terjadi karena adanya las. Variasi arus yang digunakan adalah 70 A, 80 A dan 90 A. Sedangkan variasi elektroda yang digunakan adalah E6013 dan E7016. Hasil yang didapat dari penelitian ini adalah tidak ada cacat permukaan setelah dilakukan pengelasan. Selain itu didapatkan tegangan bending terbesar pada variasi elektroda E6013 dengan kuat arus 90 A sebesar 35,52 MPa.
