Abstract

The Taguchi method uses signal-to-noise ratio (S/N) analysis to obtain optimal values and requires repeated data collection combined with control factors. However, in practice, the Taguchi method is still not in accordance with this concept, even though there are standard analysis options that do not require repeated data collection. In this study, a validation study of the Taguchi method was conducted for the case of a single data collection by comparing the optimization results obtained against standard analysis and validation experiment results. Determination of validity is carried out based on four comparison parameters, namely the combination of control factors, prediction of optimum value, deviation of optimum value prediction, and ranking of control factor influence. This research was conducted using a turning process case study. From this research, it is concluded that the Taguchi method for optimization of a single data collection is valid.

Abstract

Pengolahan makanan bersih merupakan hal penting dalam menentukan kualitas makanan, dimana pedagang makanan kaki lima sebagai salah satu pelaku harus memperhatikan aspek kebersihan penjamah makanan agar tidak menyebabkan timbulnya masalah kesehatan akibat kualitas makanan yang kurang baik. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk mengetahui gambaran perilaku penjamahan makanan pada pedagang kaki lima di lingkungan kampusUNJANI Bandung, Kelurahan Kebon Kangkung dan Sukapura, Kota Bandung, tahun 2022. Partisipan dalam kegiatan berjumlah 50 responden. Data awal menunjukkan bahwa responden memiliki praktik hygiene kategori tidak memahami dengan kriteria jawaban di bawah 6 (enam) betul dari sepuluh pertanyaan sebanyak 37 responden, tingkat pengetahuan baik dengan kriteria minimal 6 (enam) jawaban yang betul dari 10 (sepuluh) yaitu 13 responden. Kegiatan pengabdian kepada masyarakat berupa pelatihan agar responden mempunyai pengetahuan dan kesadaran mengolah makanan yang hygiene penjamah makanan. Hasil kegiatan menunjukkan peningkatan pemahaman responden dengan kriteria jawaban minimal 6 (enam) dari sepuluh pertanyaan sejumlah 43 atau sebesar 86% dari total responden yang mengikuti pelatihan. Pengujian dilakukan dengan menggunakan metode perbandingan Paired-T. Hasil dari pengujian menggunakan metode Paired-T menunjukkan tingkat signifikansi kurang dari 0.000 yang berarti pelatihan memberikan perubahan pemahaman responden menjadi lebih baik mengenai pengolahan makanan dengan cara yang higienis.

Abstract

Sheeting machines play a crucial role in the packaging industry, making parameter optimization essential for enhancing efficiency. This study applies the Taguchi method to optimize key operational factors: roller speed, brake frequency, and pressure. Using ANOM and ANOVA, roller speed was identified as the most influential factor, contributing 82.76% in ANOM and 87.29% in ANOVA, followed by brake frequency (7.08% in ANOM, 7.36% in ANOVA). The F-test (95% confidence interval) confirmed that pressure had an insignificant effect, leading to its exclusion via a pooling-up strategy. Error contributions remained below 15%, ensuring that no critical factors were overlooked. Among interactions, only the roller speed–pressure (A × B) interaction significantly impacted production speed. The optimized parameters increased throughput from 33 to 42 sheets/min (27.3% improvement) and enhanced production robustness (S/N ratio) from 30 to 32.49 (8.3% increase). These findings confirm the effectiveness of the Taguchi method in refining sheeting machine performance.
