Abstract

AbstractThe manufacturing industry plays a vital role in supporting economic growth but often faces operational inefficiencies, particularly in the production process. PT XYZ, a leading steel manufacturing company in Indonesia, utilizes a CNC laser cutting machine model 3015H to produce components made from SS400 material. A high defect rate in cutting 2 mm thick SS400 plates indicates inefficiencies that require further investigation. This study aims to analyze the effects of cutting speed, laser height distance, and gas pressure on cutting time efficiency and dimensional accuracy. The research employs the Taguchi method for experimental design, Grey Relational Analysis (GRA) for multi-response optimization, and MANOVA to determine the simultaneous significance of the process parameters. The results show that the optimal parameter combination for cutting time and dimensional accuracy is achieved at a cutting speed of 1.8 m/min, a laser height of 0.8 mm, and a gas pressure of 0.8 bar. Cutting speed was the most dominant factor affecting cutting time efficiency, with the fastest time recorded at 25.26 seconds and the highest delta value. Gas pressure had the most significant effect on dimensional accuracy, producing the smallest deviation of 0.0567 mm. MANOVA results indicated that all three parameters had a significant multivariate effect (p 0.05), but only cutting time was significantly affected in the univariate test. In conclusion, proper process parameter settings can enhance cutting efficiency without compromising accuracy. These findings are expected to support technical decision-making to improve productivity at PT XYZ.Keywords:cnc laser cutting; ss400; taguchi; grey relational analysis; manova  AbstrakIndustri manufaktur merupakan sektor penting yang menopang pertumbuhan ekonomi, namun dalam praktiknya sering menghadapi tantangan berupa ketidakefisienan operasional, khususnya dalam proses produksi. PT XYZ sebagai perusahaan produsen baja terkemuka di Indonesia menggunakan mesin CNC laser cutting tipe 3015H dalam produksi produk berbahan SS400. Tingginya tingkat cacat pada proses pemotongan material SS400 ketebalan 2 mm menunjukkan adanya ketidakefisienan yang perlu diteliti lebih lanjut. Penelitian ini bertujuan untuk menganalisis pengaruh parameter proses kecepatan potong, jarak ketinggian laser, dan tekanan gas terhadap efisiensi waktu dan akurasi dimensi hasil potongan. Penelitian menggunakan metode Taguchi untuk desain eksperimen, grey relational analysis (GRA) untuk optimasi multi-respon, dan uji MANOVA untuk mengetahui signifikansi pengaruh secara simultan. Hasil penelitian menunjukkan bahwa kombinasi parameter optimal untuk waktu pemotongan dan akurasi dimensi, yaitu pada kecepatan potong 1,8 m/min, jarak ketinggian laser 0,8 mm dan tekanan gas 0,8 bar. Kecepatan potong merupakan faktor paling dominan terhadap efisiensi waktu, ditunjukkan oleh waktu tercepat sebesar 25,26 detik dan nilai delta tertinggi. Sedangkan tekanan gas paling berpengaruh terhadap akurasi dimensi, dengan selisih terkecil sebesar 0,0567 mm. Uji MANOVA menunjukkan ketiga parameter berpengaruh signifikan terhadap gabungan variabel dependen secara multivariat (p 0,05), namun hanya signifikan terhadap efisiensi waktu secara univariat. Dapat disimpulkan bahwa pengaturan parameter proses yang tepat dapat meningkatkan efisiensi pemotongan tanpa mengorbankan akurasi. Hasil ini diharapkan dapat menjadi dasar pengambilan keputusan teknis dalam meningkatkan produktivitas PT XYZ.Kata Kunci:            cnc laser cutting; ss400; taguchi; grey relational analysis; manova

Abstract

The portable electric canting innovation has been developed to enhance the productivity of batik artisans in Pekalongan by considering Quality Function Deployment (QFD). This research aims to address the challenges faced in the traditional batik-making process, which is often time-consuming and labor-intensive. The research method employed includes identifying user needs, developing questionnaires, and analyzing data to evaluate user satisfaction with the electric canting. The results indicate that the portable electric canting can improve efficiency and comfort in the batik-making process while meeting users' needs for a practical and high-quality tool. Thus, this innovation is expected to contribute to the preservation of batik art in Indonesia.

Abstract

By modifying three traditional canting designs using the House of Quality (HoQ) method, this article discusses the development of a portable electric canting. The main focus of this research is to use electrical technology to improve the convenience and efficiency of the batik-making process. Each new design has a recharging system that allows the user to recharge the power source. User needs and wants were discovered and incorporated into the technical specifications of each design through HoQ analysis. Research shows that these changes not only improve tool performance but also make the batik-making process safer and more environmentally friendly. Therefore, through the development of relevant and sustainable technologies, this project contributes to the preservation of Indonesia's batik culture.
