Abstract

Taxis are one of the modes of public transportation that are often found in big cities. This study will discuss the production process of new taxis and used taxis until they become cars that are ready to be used as private vehicles by the general public. New taxis will be produced according to taxi standards set by the relevant company. Meanwhile, used taxis are cars that have been operating for 5 years as taxis, then restored to become private vehicles. The production process of new taxis includes various steps from planning to quality control, which aims to ensure that the taxis produced have high quality and a luxurious appearance. Meanwhile, the production process of used taxis requires detailed and thorough checking and processes from the time the car arrives at the production site until production is completed. Through these two processes, in-depth insights are obtained on how to maintain the performance and quality of cars, both new and used, so that they are always optimal.

Abstract

This study aims to investigate the effect of fabrication methods on the tensile strength of epoxy composites reinforced with untreated Cordyline australis fibers. Two fabrication methods were compared: closed hand lay-up and vacuum chamber. The fiber weight fractions used were 1%, 2%, and 5%. Tensile tests were conducted according to ASTM D638, and morphological characteristics were examined through surface and fracture micrograph analysis. The results show that the hand lay-up method consistently produced higher tensile strength compared to the vacuum method across all fiber fractions. The highest tensile strength was achieved at 2% fiber fraction using the hand lay-up method, reaching 26.91 MPa, while the vacuum method only reached 21.11 MPa. At 5% fiber content, the vacuum method experienced a significant drop in tensile strength to 12.34 MPa, indicating its ineffectiveness at higher fiber loadings without treatment. Micrographic analysis revealed that the vacuum method tended to produce voids and resin-poor areas around the fibers. These findings confirm that fabrication method has a significant influence on the mechanical performance of the composite, and that the hand lay-up method is more suitable for natural fiber-based composites without additional treatments.

Abstract

Overall Equipment Effectiveness (OEE) sangat penting bagi perusahaan (Desalinasi) dalam proses pemurnian air laut menjadi air minum. OEE yang biasa dikenal Perhitungan Effektivitas Peralatan Total (PEPT) digunakan untuk meminimasi downtime yang sering terjadi secara berkesinambungan guna meningkatkan effectivitas mesin sesuai dengan standar pemeliharaanyang menyatakan pengecekan setiap saat dengan menggunakan Overall Equipment Effectiveness (OEE). Overall Equipment Effectiveness (OEE) sebaagai alat ukur (Metrik) untuk mengetahui besarnya effektivitas peningkatan kualitas peralatan mesin yang dimiliki. Berdasarkan perhitungan menggunakan Overall Equipment Effectiveness (OEE) dengan nilai Availability = 43,33 nilai Performance Efficiency -12,37% dan nilai Quality Rate = 100 % dan hasil OEE = -43,59%. Ini menujukkan bahwa kualitas mesin tetap handal dalam melakukan permurnian air laut menjadi air baku.
