Abstract

Waste is a problem whose existence needs to be minimized, because waste can affect the productivity of a business. This research was conducted at UMKM Swadi Cipta Karya which operates in the convection sector with the main product being fishing bags. The main objective of this research is to minimize waste that occurs in the fishing bag production process. This research uses a lean manufacturing approach with several analysis stages in it, such as value stream mapping (VSM), waste failure mode effect analysis (WFMEA), value stream analysis tools (VALSAT), fishbone diagram, and kaizen. Data in the research were obtained through direct observation by identifying and measuring the time of activities carried out in the fishing bag production process. The results of the analysis using WFMEA conclude that there are main types of waste in the production process, namely transportation, unnecessary motion, and waiting. Analysis of tool selection using VALSAT concluded that PAM was selected to be used to eliminate waste, activities that had to be minimized were more dominant than activities that had to be eliminated (eliminated). These results also provide a layout design that can be implemented by MSMEs. Analysis using Kaizen concludes that the results of 5S are designing the layout well, arranging materials, conducting training, preparing materials, and placing sewing results in baskets to minimize or eliminate waste.

Abstract

Sudut kontak hysteresis (SKH) adalah selisih antara sudut kontak maju (advancing) dan mundur (receding). Besaran ini merupakan indikator penting dalam karakterisasi kebasahan permukaan, yang berdampak pada berbagai aplikasi teknik dan industri seperti pendinginan semprot dan material anti-icing. Tujuan penelitian ini adalah untuk mengukur sudut kontak histeresis (SKH) pada permukaan logam panas menggunakan metode tumbukan droplet campuran air dan campuran etilen glikol (20%) yang direkam dengan kamera kecepatan tinggi (2000 fps). Penggunaan kamera berkecepatan tinggi menjanjikan kemampuan menangkap fenomena pergerakan tinggi tetapi memiliki keterbatasan-keterbatasan yang harus diselesaikan seperti noise dan thermal artifact. Untuk mengatasi noise citra akibat gerakan cepat dan thermal artifact, penelitian ini menerapkan pemrosesan citra berbasis kecerdasan buatan/artificial intelligence (AI) menggunakan arsitektur CNN (ResNet-18) dan GAN (ESRGAN). Hasil menunjukkan bahwa metode ini mampu meningkatkan kualitas citra dan akurasi pengukuran sudut kontak, dengan nilai rata-rata sudut kontak advancing sebesar 80,5°, receding sebesar 32,74° dan SKH 47,76°. Pendekatan ini menawarkan solusi efektif dan presisi tinggi dalam pengukuran SKH serta memberikan kontribusi terhadap pemodelan kebasahan permukaan pada sistem dinamis.
