Abstract

Pemilihan vendor pemeliharaan kapal harus menyeimbangkan efisiensi biaya, kesiapan teknis, dan bukti kinerja. Penelitian ini mengintegrasikan Cost-Benefit Analysis (CBA), Analytic Hierarchy Process (AHP), dan machine learning untuk mengevaluasi vendor pemeliharaan mesin kapal tunda pada perusahaan jasa maritim di Surabaya. Data terdiri atas 119 transaksi tahun 2025 dari 22 vendor dan penilaian lima pakar. CBA menyaring vendor berdasarkan Benefit-Cost Ratio, sedangkan AHP menilai lima kriteria teknis. K-Means diterapkan pada profil frekuensi, nilai negosiasi, efisiensi, bulan aktif, dan proporsi pekerjaan pengadaan. Audit menemukan satu transaksi yang tidak masuk agregasi awal serta empat vendor dengan satu riwayat. Setelah normalisasi AHP, SRUJ memperoleh skor tertinggi 0,244. K-Means menghasilkan empat klaster (silhouette 0,430) dan dikonfirmasi metode Ward (ARI 1,00). SRUJ layak diprioritaskan melalui kontrak bertahap, sementara dominasi vendor perlu dikendalikan dengan pemantauan kinerja dan diversifikasi.

Abstract

Competition in the business and industrial sectors requires Vocational High School (SMK) graduates to master not only technical skills (hard skills) but also non-technical skills (soft skills). SMK Mambaul Ulum Pandaan, as a relatively new vocational school, faces challenges in preparing students for workforce entry, particularly in recruitment processes and Curriculum Vitae (CV) preparation. This Community Service program aimed to enhance students' work readiness through integrated training in three core soft skills: time management, professional communication, and CV preparation. The activity used a participatory training approach involving lectures, discussions, simulations, and hands-on practice, evaluated using a one-group pre-test–post-test design. A total of 25 students from Grade XI and Grade XII participated in the activity. The results showed an increase in the average scores of both groups, with Grade XI improving from 2.86 to 3.05 and Grade XII from 3.05 to 3.22. The N-Gain scores were 16.7% and 17.9%, respectively. The Wilcoxon signed-rank test yielded an Asymp. Sig. (2-tailed) value of 0.036, indicating a statistically significant difference between the pre-test and post-test scores. Overall, the findings indicate a positive change in students’ work-readiness scores following the training, although the relatively modest N-Gain values suggest that the magnitude of improvement was limited.
