Abstract

Human realibility is a big tricky problem. Human failure rates depend on three main factors, namelyintrinsic, work environment, and stress. PT. X is a supplier for PT. LG Indonesia manufacturing productsmade from plastics. Human Realibility Assesment is conducted using HEART methods (Human ErrorAssessment and Reduction Technique). In the first phase, task analysis on operators’ activities is done usingHierarchical Task Analysis (HTA). The largest Human Error Probability was found when Operator No. 1did not insert the flash side carefully. The value of this probability is 0.53424. This factor is concluded as themain cause to shroud defectives, which results in customer penalyzing the company.

Abstract

Penelitian pendahuluan untuk mengidentifikasi risiko ergonomi yang telah dilakukan menunjukkan bahwa operator perakitan daun sirip diffuser di PT X menghadapi risiko ketidaknyamanan dan cedera pada tubuh bagian pinggang, bahu kiri dan pegelangan tangan kiri. Intervensi ergonomi dilakukan dengan memperbaiki metode kerja dan perancangan meja perakitan yang ergonomis. Dalam perancangan fasilitas kerja, Fuzzy AHP digunakan untuk memilih konsep terbaik dari rancangan meja perakitan. Hasil perhitungan dengan Fuzzy AHP didapatkan bahwa konsep 11 memiliki bobot terbesar (44.5%). Maka, konsep 11 akan dijadikan dasar untuk merancang meja perakitan. Konsep 11 memiliki spesifikasi : rangka terbuat dari alumunium, alas permukaan terbuat dari kayu, fixture terbuat dari alumunium, pijakan kaki terbuat dari kayu dan posisi peralatan terletak di posisi atas. Usulan perbaikan ini kemudian diimplementasikan pada stasiun perakitan daun sirip. Hasil dari implementasi dan evaluasi dengan skor REBA menunjukkan penurunan tingkat risiko menjadi  2 (Low). Selain itu keluhan pekerja terhadap tubuh bagian pinggang, bahu kiri dan pegelangan tangan kiri dapat tereliminasi dan terjadi penurunan presentase keluhan. Perbaikan metode kerja menghasilkan keseimbangan aktivitas tangan kiri dan tangan kanan dan penurunan waktu siklus setiap unitnya.  Kata Kunci : Fasilitas kerja, REBA, Intervensi ergonomi   Preliminary reaserch to identify ergonomic risk that have been done show that the leaves fin diffuser operator assembly in PT X facing risk injury on the body belt, left shoulder, and left wrist.

Abstract

Distribusi gas LPG 3 Kg memerlukan perencanaan rute yang efisien untuk menekan biaya operasional, menghemat waktu, dan meningkatkan keamanan pengiriman. Penelitian ini bertujuan untuk mengoptimalkan pemilihan rute terpendek distribusi gas LPG 3 Kg dengan menerapkan Algoritma Sweep berbasis Python pada kasus Capacitated Vehicle Routing Problem (CVRP). Data yang digunakan meliputi lokasi pelanggan, jarak antar titik, dan kapasitas angkut truk. Algoritma Sweep digunakan untuk mengelompokkan pelanggan berdasarkan sudut polar relatif terhadap depot, dilanjutkan dengan penentuan urutan kunjungan yang meminimalkan jarak tempuh sambil memenuhi batas kapasitas kendaraan. Hasil optimasi menunjukkan bahwa metode ini mampu menghasilkan tiga rute distribusi dengan total jarak tempuh 98,7 km, mengalami pengurangan sebesar 26,18 km atau sekitar 21% dibandingkan kondisi awal yang mencapai 124,88 km. Selain itu, jumlah armada dapat ditekan menjadi tiga truk tanpa melanggar batas kapasitas angkut. Implementasi berbasis Python memungkinkan proses penghitungan dan pemodelan rute dilakukan secara cepat, akurat, dan dapat diulang untuk berbagai skenario distribusi.
