Final Project: The Effect of Banana Peel Cellulose Fiber Inclusion in Palm Oil-Based Cutting Fluid on the Surface Roughness of Work Piece.

  • Conducted experimental machining on AISI 4340 steel using a spindle speed of 900 rpm and depth of cut 0.5 mm. Utilized Surface Roughness Tester (Mitutoyo SJ-301) and ANOVA analysis to identify the optimal concentration (3%) for minimizing surface roughness (Ra) and tool wear.

Pengalaman Kerja

2024
PT Semen PadangMaintenance Engineer Intern
  • Conducted a comprehensive technical study on shaft misalignment issues of the Chain Bucket Elevator (6R1J09) at the Indarung VI Raw Mill area to understand its impact on production continuity.
  • Executed detailed technical analysis, calculating a precise vertical deviation of 3.617 mm based on an inclination angle of 0.1° to pinpoint failure modes.
  • Evaluated root causes using Root Cause Analysis (RCA) methods, identifying structural deformation of the frame casing due to uneven load distribution as the primary factor.
  • Formulated data-driven corrective strategies, proposing specific re-shimming (3.6 mm) and structuralreinforcement to restore alignment and extend bearing service life.

2023 - 2025
Core Technology Production LaboratoryLaboratory Assistant
  • Supervised daily machining operations (Lathe, Milling, Drilling) for 700+ students across 7 batches, ensuring zero accidents through strict HSE (Health, Safety, Environment) & SOP enforcement.
  • Executed end-to-end production planning for 90+ precision material test specimens (Tensile Test ASTM E8 & Impact Test ASTM E23), ensuring dimensions met strict tolerance standards for external research clients.
  • Performed rigorous dimensional inspection (QC) using Micrometer to ensure every specimen met the specific thickness and diameter requirements before delivery, achieving a high acceptance rate.
  • Spearheaded the standardization of lab procedures by co-authoring the official practicum guide, ensuring technical documentation was up to date with current manufacturing standards.
  • Managed inventory of raw materials (AISI Steel, Aluminum) and cutting tools, ensuring operational readiness through routine preventive maintenance (lubrication & belt replacement) to minimize machine downtime.
