HAZARD IDENTIFICATION AND ASSESSMENT OF OCCUPATIONAL SAFETY AND HEALTH RISKS USING THE HIRA METHOD
(Politeknik Negeri Batam, 2026-07-31) Holy Devida Boflen, Hankho; Puspitasari, Ayu
Occupational Safety and Health (K3) is an important aspect in reducing the potential for accidents in high-risk work environments. This research uses a descriptive analysis method with the HIRA (Hazard Identification and Risk Assessment) approach which aims to identify hazards and carry out risk assessments in heavy equipment maintenance and repair work activities. The research results show that the main potential hazards are in welding, painting and installation activities cylinder boom on excavator. Welding and painting activities fall into the category risk trivial until moderate risk, while the installation cylinder boom including moderate risk until substantial risk. Occupational risks are influenced by unsafe behavior, non compliance with PPE use, and work area conditions that are not fully safe. The main factors causing high risks are non-compliance with PPE use, unsafe work areas, and the absence of HIRA (Hazard Identification and Risk Assessment) documentation. This study recommends strengthening supervision of PPE use, preparing HIRA (Hazard Identification and Risk Assessment) documents formal, implementation engineering control, as well as updates SOP in high-risk activities. With this implementation, companies are expected to reduce accident rates and improve their work safety culture.
Rekomendasi Pemilihan Mahasiswa Berprestasi Menggunakan Metode Simple Additive Weighting (SAW) Studi Kasus: Politeknik Negeri Batam
(Politeknik Negeri Batam, 2026-06-06) Juliansyah Putra, Surya; Adam, Chairoel
Penelitian ini bertujuan untuk mengembangkan sistem rekomendasi berbasis web untuk membantu Politeknik Negeri Batam dalam menyeleksi mahasiswa berprestasi (Pilmapres) secara objektif dan efisien. Saat ini, proses seleksi masih dilakukan secara manual, yang memakan waktu dan rentan terhadap bias karena jumlah peserta meningkat setiap tahunnya. Sistem yang diusulkan mengintegrasikan metode Simple Additive Weighting (SAW) untuk pemeringkatan kandidat. Dengan mengotomatiskan evaluasi berdasarkan kriteria seperti prestasi akademik, prestasi non-akademik, kepemimpinan, dan kontribusi sosial, sistem ini memastikan proses pengambilan keputusan yang lebih transparan dan terstruktur. Aplikasi ini diharapkan dapat mempercepat proses kurasi dan meningkatkan kualitas perwakilan mahasiswa di tingkat nasional.
IMPLEMENTASI AUDIT LOG DAN VALIDASI DATA PADA APLIKASI FORM REGISTRASI IT BERBASIS WEB DI PT ECOGREEN OLEOCHEMICALS
(Politeknik Negeri Batam, 2026-07-22) Kevin Sebastian, Theodore Kevin; Yunus, Rusyda Nazhirah
PT Ecogreen Oleochemicals menggunakan aplikasi formulir registrasi IT berbasis web untuk mengelola pengajuan hak akses operasional karyawan. Namun, sistem yang sebelumnya berjalan memiliki kelemahan, yaitu ketiadaan validasi input yang rentan memicu error pada database akibat penggunaan karakter khusus, serta tidak adanya mekanisme pencatatan riwayat penghapusan data. Hal ini berdampak pada rendahnya akuntabilitas dan hilangnya rekam jejak digital secara permanen. Proyek akhir ini bertujuan untuk mengembangkan sistem baru dengan mengimplementasikan fitur validasi data secara real-time dan audit log berbasis mekanisme soft delete. Pengembangan sistem dilakukan menggunakan metode Waterfall yang mencakup tahapan analisis, perancangan, implementasi, dan pengujian. Aplikasi ini dibangun menggunakan bahasa pemrograman PHP dengan database MariaDB, dan dikonfigurasi menggunakan arsitektur kontainer Docker di atas Ubuntu Server. Hasil pengujian menggunakan metode User Acceptance Testing (UAT) menunjukkan bahwa seluruh skenario pengujian berhasil beroperasi dengan baik (status Pass). Fitur validasi terbukti efektif memblokir karakter terlarang (forbidden characters) dan mencegah duplikasi, sementara penerapan soft delete berhasil menjaga integritas data dengan mencatat setiap aktivitas penghapusan ke dalam halaman Log Deleted. Kesimpulannya, implementasi ini berhasil meningkatkan efisiensi proses approval, mencegah kesalahan input pengguna, serta menciptakan tata kelola administrasi IT yang lebih transparan dan dapat diaudit.
ANALISIS HUBUNGAN REMUNERASI BERBASIS KINERJA TERHADAP KINERJA PEGAWAI DAN KEPUASAN KERJA PADA POLITEKNIK PARIWISATA BATAM
(Politeknik Negeri Batam, 2026-08-21) Harahap, Raja Parlindungan; Anjelina
This study examines the relationship between performance-based remuneration and both employee performance and job satisfaction at Batam Tourism Polytechnic, and compares the relative strength of these two relationships. A quantitative, correlational design was applied, using a saturated sampling technique that covered all employees meeting the study's criteria. Data were gathered through a Likert-scale questionnaire and processed using descriptive statistics, validity and reliability tests, a normality test, and the Pearson Product-Moment correlation, all computed in IBM SPSS. The analysis reveals that performance-based remuneration is positively and significantly associated with both employee performance and job satisfaction, with the link to job satisfaction proving stronger than the link to performance. These results suggest that a remuneration system applied fairly, transparently, punctually, and in line with actual work achievement not only drives better employee performance but also meaningfully strengthens job satisfaction within a vocational higher-education setting.
IoT Based Condition Monitoring System for Spot Welding Machines Using Vibration and Non Contact Voltage Detection
(Politeknik Negeri Batam, 2026-07-01) Tamba, Yitro Adi; Arifin, Muhammad
This study developed an Internet of Things (IoT)-based spot welding machine condition monitoring system that integrates an MPU6050 sensor, a non-contact voltage detector, an ESP32, a TFT LCD screen, and the Blynk platform. Vibration acceleration values were calculated based on changes in resultant acceleration relative to the stationary baseline and processed using an exponential moving average. Testing was conducted under normal operating conditions and increased- vibration conditions. Under normal conditions, peak vibration acceleration values ranged from 0.90 to 6.79 m/s², while under increased-vibration conditions, they ranged from 7.10 to 9.15 m/s². The response time of the system components ranged from 0.1 to 0.5 seconds. This system can display data locally and send data to Blynk. However, further validation using reference instruments is still needed to determine the measurement accuracy of the develoved monitoring system.
