Abstract

Many commercial packages use sandwich composite materials, and this search takes advantage of ANSYS software to evaluate their bending behaviors. FEM gives a good understanding of material behavior with the exposure of outdoor forces. The construction of the sandwich production that accounts for its many layers, as well as for the characteristic features of the materials used is an important aspect of this examination.

Abstract

This study aims to identify, analyze, and provide solutions to bottlenecks in the plastic cup production process at PT 'X'. The bottleneck caused by static electricity lamps led to a decrease in production efficiency, with a downtime of up to 20 minutes per day and a reduction in capacity by 450,000 cups per month. The Capacity Requirement Planning (CRP) method and cycle time analysis were employed to evaluate machine capacity and identify the root causes of production constraints. After improvements, including the addition of static electricity eliminators, the cycle time was optimized from 0.108 seconds/cup to 0.0864 seconds/cup, downtime significantly reduced to 2 minutes per day, and defective products decreased by up to 80%. Production capacity increased from 2.4 million to 3 million cups per day, meeting the target. This study highlights that eliminating bottlenecks through technological optimization can significantly enhance production efficiency and the company's competitiveness.

Abstract

Studi ini bertujuan untuk memeriksa penerapan RCCP dan TOC dalam perencanaan kapasitas produksi di Bengkel Cor Logam Sentosa Jaya. Latar belakang penelitian ini berasal dari tantangan dalam mengelola kapasitas produksi. Pendekatan penelitian kualitatif digunakan, dengan memanfaatkan metode pengumpulan data seperti observasi dan wawancara. Analisis RCCP mengungkapkan kelebihan kapasitas sebesar - 2% pada stasiun pengecoran, yang mengindikasikan kapasitas yang tidak mencukupi untuk memenuhi target produksi. Sementara itu, analisis TOC mengidentifikasi stasiun pengikiran dan pemolesan sebagai kendala utama dalam sistem produksi karena memiliki kapasitas maksimum terendah. Penerapan gabungan metode RCCP dan TOC terbukti efektif dalam menganalisis kendala di Bengkel Cor Logam Sentosa Jaya. Untuk mengatasi kendala tersebut, solusi yang paling efisien adalah menambahkan satu jam lembur bagi pekerja di kedua stasiun baik pengikiran dan pemolesan, sehingga meminimalkan penumpukan di stasiun pengecoran. Setelah kami melalukan pangambilan data dengan pemilik bengkel dan pengolahan data dengan menggunakan metode RCCP dan juga TOC solusi yang paling efektif adalah menambah 1 jam lembur setiap hari, sehingga total jam kerja menjadi 8-9 jam per hari. Penyesuaian ini akan meningkatkan kapasitas workstation pengikiran dan pemolesan dari 3715,2unit menjadi 5056,8unit dan pemolesan dari 3302,4unit menjadi 4179,6 unit.

Abstract

This study aims to predict the residual performance resource of pneumatic tires used in agricultural machinery, particularly tractors, to optimize their lifespan and maintenance strategies. Understanding the durability and wear characteristics of pneumatic tires is essential for ensuring efficiency and reducing unexpected failures. The research employs static and dynamic prediction methods to estimate the remaining service life of tractor tires. The static prediction assumes a linear degradation over time, while the dynamic prediction incorporates periodic evaluations of tire conditions, allowing for more precise estimations. The study follows ISO 13381-1:2015 standards for machine condition monitoring and diagnostics, integrating statistical models and probability analysis to assess failure rates and maintenance schedules. The results indicate that dynamic prediction provides a more accurate assessment of residual tire life compared to static methods. The study also finds that proper monitoring can significantly extend the operational lifespan of tractor tires, reducing maintenance costs and minimizing machine downtime. With a 95% confidence level, the research confirms that effective diagnostics and predictive maintenance strategies enhance the reliability and efficiency of agricultural machinery.

Abstract

Penelitian ini bertujuan untuk menganalisis efektivitas mesin pengisi cairan otomatis pada industri makanan dengan menggunakan metode Overall Equipment Effectiveness (OEE). PT Y, sebagai objek studi, menghadapi tantangan berupa downtime mesin, penurunan kecepatan produksi, serta produk cacat yang mengganggu efisiensi proses produksi. Dengan pendekatan kuantitatif deskriptif, data dikumpulkan melalui observasi, wawancara, dan dokumentasi produksi selama periode Januari hingga Desember 2024. Tiga indikator utama OEE—availability, performance efficiency, dan quality rate—dihitung untuk mengevaluasi kinerja mesin. Hasil menunjukkan bahwa nilai OEE tertinggi terjadi pada bulan Desember sebesar 80,34%, sementara nilai terendah tercatat pada Oktober dengan 66,97%. Faktor utama penyebab rendahnya efektivitas adalah downtime dan penurunan kecepatan produksi. Analisis fishbone dilakukan untuk mengidentifikasi akar permasalahan, yang meliputi aspek manusia, mesin, metode, dan material. Penelitian ini menyimpulkan bahwa meskipun efektivitas mesin berada pada tingkat yang cukup baik, masih diperlukan perbaikan di semua aspek untuk mencapai standar OEE kelas dunia. Rekomendasi difokuskan pada peningkatan program perawatan preventif dan pelatihan operator untuk meminimalkan losses.
