Abstract

Mastery of mixed methods is crucial for researchers to produce high-quality research and publish their results in reputable journals. Expertise in mixed methods research is essential across various disciplines, both for research purposes, publication of research articles, and both. This workshop was conducted to meet the needs of lecturers and postgraduate students at Batam University. The methods used were lectures and practical data processing. The workshop also included practical quantitative data processing with Lisrel software and practical qualitative data processing with NVivo software. The workshop delivered excellent results. 98% of participants understood and were able to independently conduct mixed methods research, including processing research data with Lisrel and NVivo software. However, workshop participants were advised to review all workshop materials and immediately implement everything learned from this research methods workshop.

Abstract

Industri kertas daur ulang menghadapi tingkat cacat produksi kertas board rata-rata 9,24% per bulan, jauh di atas batas toleransi perusahaan sebesar 2%. Kondisi ini menunjukkan bahwa pengendalian kualitas yang bersifat inspektif dan reaktif belum mampu mengurangi variasi proses secara efektif. Penelitian ini bertujuan mengidentifikasi faktor yang paling berpengaruh terhadap cacat dominan serta merumuskan rekomendasi perbaikan proses menggunakan metode Taguchi. Tahapan penelitian meliputi identifikasi cacat dominan dengan diagram Pareto, analisis akar penyebab menggunakan diagram Fishbone, perancangan eksperimen matriks ortogonal L9, analisis Signal-to-Noise Ratio dengan kriteria smaller is better, dan Analysis of Variance menggunakan Minitab 19. Hasil penelitian menunjukkan bahwa faktor dominan pada setiap jenis cacat adalah tekanan roller untuk kertas robek (78,94%), tekanan semprot untuk cacat tidak ter-coating (51,49%), kecepatan mesin potong untuk cacat tidak terpotong (79,46%), dan jenis material untuk cacat gramatur tinggi (70,82%). Kombinasi parameter optimal yang direkomendasikan meliputi tekanan roller 90 kN/m, suhu pengeringan 130°C, dan material campuran, yang kemudian diterjemahkan ke dalam rencana tindakan berbasis 5W+1H untuk mendukung penurunan cacat produksi secara sistematis dan berkelanjutan.
