Abstract

In today's increasingly globalized industrial competition and rapid technological advancements, manufacturing companies strive to improve the quality and quantity of their products. However, intensive use and occasional overloading of machines can lead to decreased performance, shortened lifespan, and component failures. Machine failures not only cause costly downtime but also pose safety risks to workers. This study focuses on PT. Mah Sing Indonesia's efforts to optimize the injection molding process by addressing machine downtime through effective preventive maintenance strategies and comprehensive management approaches. Data collected over the course of 2023 highlights the application of Overall Equipment Effectiveness (OEE) metrics to evaluate machine performance and identify key areas for improvement. The findings underscore the significance of integrating human resources, technology, management practices, and environmental factors to enhance operational efficiency and productivity in injection molding processes.

Abstract

Supplier selection is important in the production process, because raw materials greatly affect product results and production continuity. In Bananas Food Micro, Small and Medium Enterprises (MSMEs) located in Bekasi Regency, the main problem faced is that there is no mechanism or system for selecting the right raw material suppliers to meet production needs. Bananas Food MSMEs have also not implemented a method in supplier selection, so they have more than one supplier. This research was conducted using the Analytical Hierarchy Process (AHP) method. The criteria that are prioritized in supplier selection include availability, quality, and price and location. This study aims to determine the best supplier from several alternative suppliers. Based on the results of ranking the selection of banana raw material suppliers using the AHP method, determining supplier B as the best supplier for Bananas Food MSMEs with a weight value of 0.46, supplier C as the second alternative with a weight of 0.25, supplier D as the third alternative with a weight of 0.18, and supplier A as the fourth alternative with a weight of 0.11.

Abstract

Masalah utama yang dihadapi pada penelitian ini adalah tingginya waktu siklus produksi dan adanya aktivitas-aktivitas yang tidak memberikan nilai tambah yang menyebabkan hasil produksi tidak memenuhi target. Penelitian ini bertujuan untuk mengidentifikasi penyebab utama pemborosan (waste) dalam proses produksi holder motor di PT TTB  melalui penerapan lean manufacturing dengan bantuan value stream mapping. Hasil analisis process activity mapping menunjukkan bahwa delay (waktu tunggu) merupakan jenis pemborosan yang paling dominan, menyumbang 10 aktivitas dengan total 357,1 detik atau 28% dari keseluruhan proses produksi, berdasarkan identifikasi tersebut, dirancang usulan perbaikan yang diproyeksikan dapat mengurangi total lead time proses produksi dari 627,1 detik menjadi 460 detik, terutama akibat penghapusan aktivitas non-value added yang turun dari 285,1 detik menjadi 148 detik. Selain itu, aktivitas necessary but non-value added juga mengalami penurunan dari 60 detik menjadi 30 detik. Perubahan ini menunjukkan peningkatan proporsi waktu yang memberikan nilai tambah bagi perusahaan. Secara khusus, pengurangan waktu pada tahap menyiapkan APD (berkurang 50% NVA), melakukan daily check (berkurang 50% NVA), dan trimming (berkurang 38% NVA) menjadi faktor terbesar dalam menekan pemborosan waktu tunggu serta aktivitas yang tidak bernilai tambah. Usulan perbaikan mencakup penyesuaian layout, standarisasi prosedur kerja, perbaikan aliran material dan informasi, serta penerapan perawatan mesin yang terjadwal.

Abstract

Penelitian ini diadakan dengan maksud untuk meningkatkan mutu produk biskuit coklat merek Lovbis yang sedang dikembangkan untuk memperkuat posisinya di pasar. Permasalahan utama yang dihadapi adalah kurangnya variasi rasa, desain bentuk dan kemasan yang sederhana, serta belum terpenuhinya preferensi konsumen secara optimal. Untuk mengatasi permasalahan tersebut, digunakan pendekatan Quality Function Deployment (QFD) guna mengidentifikasi dan menerjemahkan kebutuhan konsumen ke dalam atribut teknis produk. Penelitian dilakukan dengan metode survei menggunakan kuesioner berbasis skala likert yang disebarkan kepada 30 responden, kemudian hasilnya divalidasi dan dianalisis melalui penyusunan House of Quality (HOQ). Hasil penelitian menyatakan terhadap atribut rasa manis berada di urutan kepentingan tertinggi sebesar 8,63%, sedangkan atribut dengan gap tertinggi antara kepuasan dan harapan konsumen adalah rasa enak dengan nilai -1,5. Respon teknis dengan bobot relatif tertinggi adalah bahan baku, yang menjadi prioritas utama dalam pengembangan produk. Simpulan dari penelitian ini adalah bahwa peningkatan kualitas produk Lovbis harus difokuskan pada perbaikan bahan baku, penambahan variasi rasa, dan pengembangan desain produk yang lebih menarik.

Abstract

PT. XYZ is a medical device manufacturing company that produces components for syringes, one of which is the Barrel product. The Barrel product has high demand, so effective quality control is essential to reduce the defect rate. This study aims to analyze ways to reduce defects in the Barrel product using the Kaizen and Plan-Do-Check-Action (PDCA) methods. In the planning phase (Plan), the dominant types of defects were identified using a Pareto diagram, which revealed three main defect types, with shortmold as the primary focus. The causes of this defect were analyzed using a Fishbone diagram. In the Do phase, corrective actions were implemented by setting objectives and goals for improvement, as well as identifying defective products with the help of the 5W+1H tool. The Check phase involved further inspection using a Check Sheet to analyze data showing a reduction in defects between October 2023 and January 2024. In the Action phase, quality control was implemented by monitoring employee performance and product quality, as well as evaluating the results of the improvements. The results of the study indicate a significant reduction in the number of defective products following the implementation of corrective actions.
