Abstract

  AbstractEvaluating safety in higher vocational education demands context-specific tools, rather than standard industrial checklists. Academic welding workshops pose significant occupational risks. Students are exposed to hazards such as heavy metal fumes, extreme temperatures, and radiation. Often, institutions rely on corporate audit templates, which may not align with the high-turnover, low-experience environment of a polytechnic laboratory. To address this, this study constructed an Occupational Health and Safety (OHS) index specifically for vocational higher education. Integrating a two-stage Delphi panel with the Analytical Hierarchy Process (AHP), academics and safety auditors distilled broad regulations into five core pillars. AHP calculations identified Local Exhaust Ventilation (C1) as the highest priority, with a weight of 0.416. The expert judgments were highly consistent (CR = 0.024). Applying this index in a field audit at a Jakarta polytechnic, the facility earned an overall compliance score of 61.03 out of 100. While the workshop scored 85 for enforcing personal protective equipment (PPE), it scored 50 for source ventilation. These results highlight the limitations of partial compliance. Relying on PPE while lacking adequate fume extraction may provide insufficient protection. This framework offers a data-backed guide for institutions to prioritize localized exhaust networks to better protect students' respiratory health.Keywords:Welding safety; Vocational education; Delphi method; Analytical Hierarchy Process; Risk assessment.. AbstrakEvaluasi keselamatan kerja pada perguruan tinggi vokasi membutuhkan instrumen spesifik secara konteks, alih-alih checklist industri standar. Bengkel pengelasan akademik memiliki risiko keselamatan kerja yang signifikan. Mahasiswa sering terpapar berbagai bahaya seperti emisi asap logam berat, suhu ekstrem, dan radiasi. Seringkali, institusi pengelola bergantung pada templat audit perusahaan komersial, yang mungkin tidak selaras dengan lingkungan laboratorium politeknik yang memiliki tingkat pergantian pengguna yang tinggi dengan tingkat pengalaman yang rendah. Untuk mengatasi hal ini, penelitian ini menyusun indeks Keselamatan dan Kesehatan Kerja (K3) khusus untuk pendidikan tinggi vokasi. Dengan mengintegrasikan panel Delphi dua tahap dan Analytical Hierarchy Process (AHP), para akademisi dan auditor keselamatan menyaring berbagai regulasi menjadi lima pilar utama. Perhitungan matriks AHP mengidentifikasi Sistem Ventilasi Lokal (C1) sebagai prioritas tertinggi dengan bobot 0,416. Penilaian dari para pakar tersebut terbukti sangat konsisten (CR = 0,024). Penerapan indeks ini dalam audit lapangan di sebuah politeknik di Jakarta menunjukkan bahwa fasilitas tersebut memperoleh skor kepatuhan keseluruhan sebesar 61,03 dari skala 100. Meskipun bengkel praktik tersebut memperoleh skor 85 untuk penegakan Alat Pelindung Diri (APD), skor untuk ventilasi penangkap asap di sumbernya hanya mencapai 50. Hasil penelitian ini menyoroti keterbatasan dari kepatuhan keselamatan yang bersifat parsial. Bergantung pada penyediaan APD sembari kekurangan infrastruktur ekstraksi asap yang memadai dapat memberikan perlindungan yang tidak mencukupi. Kerangka kerja ini menawarkan panduan berbasis data bagi institusi untuk memprioritaskan pengadaan jaringan exhaust lokal guna melindungi kesehatan pernapasan mahasiswa dengan lebih efektif. Kata Kunci:Keselamatan pengelasan, Pendidikan vokasi tinggi, Metode Delphi, Analytical Hierarchy Process, Penilaian fasilitas.

Abstract

   AbstractThe increasingly intense industrial competition requires companies to maintain the reliability and efficiency of production machinery to ensure that product quality and quantity remain optimal. One of the most important pieces of equipment in the mining production process is the belt conveyor, which functions to continuously transport materials. Failures in bearing components can lead to downtime, reduced productivity, and increased maintenance costs. This study was conducted at PT. Mifa Bersaudara with the objective of analyzing the causes of bearing failures in belt conveyors using the Failure Mode and Effects Analysis (FMEA) method. Research data were collected through field observations, interviews with the maintenance division, and records of equipment failures during the period of June–July 2023. The analysis was carried out by evaluating three key FMEA parameters: Severity (S), Occurrence (O), and Detection (D), to determine the Risk Priority Number (RPN) for identifying potential failures in a system, component, or process, as well as their causes and impacts. The results of the analysis indicate that the Inner Ring component has the highest RPN value of 175, followed by the Outer Ring (144) and the Cage (120), indicating that these components have the highest risk of failure and therefore require priority attention in maintenance and preventive actions.  Keywords:Belt Conveyor, Bearing, FMEA, RPN, Fishbone     AbstrakPersaingan industri yang semakin ketat menuntut perusahaan untuk menjaga keandalan dan efisiensi mesin produksi agar kualitas serta kuantitas produk tetap optimal.

Abstract

AbstractHospitals are critical facilities required to remain structurally safe and fully operational following an earthquake. This study aims to evaluate the seismic performance and structural compliance of the Fandika Takengon General Hospital Building following a configuration change from the initial plan of six stories to four stories. The evaluation was conducted through three-dimensional modeling using CSI ETABS software based on SNI 1726:2019 on a dual system consisting of a Special Moment Resisting Frame System (SMRFS) and shear walls. The evaluated parameters include base shear force, modal mass participation, inter-story drift, dual system contributions, and structural irregularities. The analysis results indicate that the structure complies with the global seismic response requirements based on SNI 1726:2019, with a base shear force of 13,522.52 kN in the X-direction and 13,568.53 kN in the Y-direction, and all inter-story drift values fall below the allowable limits. The moment-resisting frame is capable of resisting more than 25% of the seismic force, thereby satisfying the dual system requirements. Nonetheless, torsional irregularities were still identified on several floors, along with a mass irregularity on the second floor, and a re-entrant corner irregularity in the Y-direction, which potentially affect the local structural response during a strong earthquake. This study demonstrates that a comprehensive seismic performance evaluation is critical for existing buildings undergoing configuration changes, as compliance with global response requirements does not fully guarantee the absence of potential local vulnerabilities. The findings of this study are expected to serve as a reference for the evaluation and verification of structural safety in hospital buildings and other essential structures prior to operation.Keywords:Dual system; reinforced concrete; response-spectrum analysis; seismic performance; structural irregularity AbstrakRumah sakit merupakan bangunan dengan fungsi penting yang dituntut tetap aman secara struktural dan mampu mempertahankan operasionalnya setelah terjadi gempa bumi. Penelitian ini bertujuan mengevaluasi kinerja seismik dan kesesuaian struktur Gedung Rumah Sakit Umum Fandika Takengon setelah perubahan konfigurasi dari rencana awal enam lantai menjadi empat lantai. Evaluasi dilakukan melalui pemodelan tiga dimensi menggunakan perangkat lunak CSI ETABS berdasarkan SNI 1726:2019 pada sistem ganda yang terdiri atas Sistem Rangka Pemikul Momen Khusus (SRPMK) dan dinding geser. Parameter yang dievaluasi meliputi gaya geser dasar, partisipasi massa modal, simpangan antar tingkat, kontribusi sistem ganda, serta ketidakberaturan struktur. Hasil analisis menunjukkan bahwa struktur memenuhi persyaratan respons seismik global berdasarkan SNI 1726:2019, dengan gaya geser dasar sebesar 13.522,52 kN pada arah X dan 13.568,53 kN pada arah Y, serta seluruh nilai simpangan antar tingkat berada di bawah batas yang diizinkan. Rangka pemikul momen mampu menahan lebih dari 25% gaya gempa sehingga persyaratan sistem ganda terpenuhi. Namun demikian, masih teridentifikasi ketidakberaturan torsi pada beberapa lantai, ketidakberaturan massa pada lantai dua, dan ketidakberaturan sudut dalam pada arah Y yang berpotensi memengaruhi respons lokal struktur saat terjadi gempa kuat. Penelitian ini menunjukkan bahwa evaluasi kinerja seismik secara komprehensif sangat penting dilakukan pada bangunan eksisting yang mengalami perubahan konfigurasi, karena terpenuhinya persyaratan respons global belum sepenuhnya menjamin tidak adanya potensi kerentanan lokal. Hasil penelitian ini diharapkan dapat menjadi acuan dalam evaluasi dan verifikasi keamanan struktur bangunan rumah sakit maupun bangunan penting lainnya sebelum dioperasikan.Kata kunci:Analisis respons spektrum; beton bertulang; ketidakberaturan struktur; kinerja seismik; sistem ganda
