Structured Defect Data-Based K-Means Clustering Analysis and Framework for Quality Control (QC) Prioritization in Manufacturing
No full textQuality Control (QC) sangat penting dalam manufaktur untuk memastikan kualitas produk dan meminimalisir cacat produk. Namun, meningkatnya kompleksitas produk dan proses manufaktur telah membuat identifikasi dan prioritas cacat untuk QC menjadi lebih menantang, sementara sebagian besar studi hanya berfokus pada inspeksi visual. Oleh karena itu, studi ini mengusulkan analisis berbasis data cacat terstruktur dan kerangka kerja untuk menemukan prioritas dalam proses QC. Kerangka kerja ini menggunakan pengelompokan K-Means untuk mengelompokkan cacat berdasarkan karakteristiknya, seperti jenis, lokasi, dan tingkat keparahan yang memengaruhi tingkat biaya perbaikan. Untuk memvalidasi model, Davis-Bouldin Index dan Silhouette Score digunakan untuk mengukur kualitas model. Eksplorasi data menunjukkan bahwa setiap fitur memiliki hubungan serta dampak terhadap biaya perbaikan di mana tingkat keparahan yang lebih besar sejalan dengan biaya perbaikan yang lebih tinggi. Penemuan menunjukkan bahwa cluster 0 adalah yang harus diprioritaskan karena memiliki biaya perbaikan tertinggi di antara yang lain. Hasil penelitian menunjukkan bahwa kerangka kerja tersebut dapat secara efektif mengidentifikasi dan memprioritaskan cacat untuk QC, yang berpotensi mengarah pada peningkatan kualitas produk dan pengurangan biaya manufaktur
Perancangan Sistem Kontrol Ketinggian Muka Cairan Pada Tangki Spherical Menggunakan Kontroler PID-Gain Scheduling
No full textTangki spherical adalah salah satu tangki pressure vessel yang memiliki bentuk yang sangat nonlinear karena bentuk geometrisnya dan tangki ini banyak digunakan pada industri untuk menyimpan cairan dengan kapasitas besar. Tangki spherical ini banyak digunakan karena keunggulannya untuk mendistribusi tegangan yang lebih merata sehingga cenderung tidak memiliki titik lemah, dan juga luas permukaan per satuan volume yang dimiliki lebih kecil membuatnya panas yang ditransferkan dari lingkungan lebih kecil dibandingkan bentuk tangki lainnya. Pengendalian ketinggian muka cairan pada tangki ini menjadi tantangan karena sifat nonlinearnya yang menyebabkan dinamika proses bervariasi secara ekstrem. Penelitian ini mengusulkan metode kontrol PID dengan pendekatan Gain Scheduling (PID-GS) untuk mengatasi tantangan tersebut. Metode ini memungkinkan parameter kontrol beradaptasi dengan melakukan penjadwalan sesuai perubahan kondisi operasi. Simulasi pada penelitian ini menggunakan MATLAB Simulink untuk mengevaluasi performa PID-GS dibandingkan PID konvensional pada berbagai setpoint. Hasil simulasi menunjukkan bahwa PID-GS memiliki rise time lebih cepat, final value lebih akurat, dan overshoot yang lebih kecil dibandingkan PID konvensional. Selain itu, PID-GS memberikan stabilitas sistem yang lebih baik dengan settling time yang lebih singkat. Analisis kesalahan kumulatif menggunakan parameter seperti IAE, ITAE, ITSE, dan ISE menunjukkan bahwa PID-GS unggul pada setpoint rendah hingga menengah. Namun, peningkatan kesalahan kumulatif pada setpoint tinggi menunjukkan perlunya optimasi lebih lanjut terhadap parameter Gain Scheduling. Secara keseluruhan, PID-GS menawarkan solusi kontrol yang efektif dan efisien untuk sistem non-linear seperti tangki spherical, dengan potensi untuk dikembangkan lebih lanjut guna meningkatkan kinerja di seluruh rentang operas

Optimalisasi Jaringan MPLS Pada Router Nokia Menggunakan Segment Routing Dengan Service VPLS dan VPRN
No full textPenelitian ini dilatarbelakangi oleh meningkatnya kebutuhan kecepatan internet yang menjadi tantangan seiring berkembangnya teknologi dan jumlah perangkat terkoneksi, terutama dengan pesatnya pertumbuhan IoT. Teknologi Segment Routing berbasis MPLS dirancang untuk meningkatkan efisiensi routing dengan kontrol jalur trafik yang lebih fleksibel. Penelitian ini bertujuan untuk optimalisasi sistem jaringan MPLS Segment Routing dengan layanan VPLS dan VPRN sehingga menghasilkan efisiensi dalam traffic forwarding sehingga menghasilkan nilai QOS yang baik. Metode penelitian meliputi perancangan topologi yang menggunakan 7 buah virtual router, 2 buah server ubuntu, 2 buah switch, dan 2 buah virtual windows yang disimulasikan pada simulator GNS3. Terdapat tiga skenario pengujian: (1) VPRN dengan link normal, (2) VPLS dengan link normal, dan (3) VPRN dan VPLS dengan link failure. Dari hasil pengujian dengan tiga skenario tersebut dilakukan analisa pola label paket data, performa QoS dengan parameter Throughput dan Delay berdasarkan standar TIPHON, dan waktu link recovery saat link failure. Hasilnya, throughput VPRN lebih tinggi (download 307 KBps, upload 311.2 KBps) dibandingkan VPLS (download 280.2 KBps, upload 303.8 KBps). VPRN juga memiliki delay lebih rendah (download 2.748 ms, upload 2.824 ms) dibandingkan VPLS (download 3.120 ms, upload 2.894 ms). Dalam link recovery, VPRN lebih cepat (1.248 ms) dibandingkan VPLS (1.253 ms). Dari semua hasil pengujian tersebut masuk dalam kategori 4, yaitu sangat baik dalam standar TIPHON. Kesimpulannya, service VPRN pada jaringan MPLS Segment Routing lebih unggul dalam parameter QoS throughput, delay, dan recovery link failure dibandingkan VPLS, sehingga lebih efektif untuk mendukung kebutuhan trafik data berkecepatan tinggi dan stabilitas koneksi di masa depan

The results showed that perceived organizational support had a negative and significant effect on turnover intention. Compensation had a negative and significant effect on turnover intention. Job satisfaction had a negative and significant effect on turnover intention. Perceived organizational support and compensation had a positive and significant effect on job satisfaction. The role of job satisfaction as a mediator of the influence of perceived organizational support on turnover intention was proven to have a negative and significant effect. Likewise, job satisfaction was proven to mediate the influence of compensation on turnover intention, which was proven to have a negative and significant effect
Financial and Macroeconomic Ratio Analysis Against Financial Distress
No full textThis study aims to analyze the effect of financial ratios and macroeconomic factors on financial distress in trade, service and investment sector companies during the 2018-2021 period. The sampling method used a purposive sampling technique with a total sample of 58 companies. Testing was carried out using E-Views using the panel data regression analysis method. Financial distress is measured using the Altman Z-Score where the higher the value indicates the healthier the company. The results showed that the profitability ratios as measured by Return on Assets had a significant positive effect on financial distress. That is, the higher the Return on Assets, the healthier the company's finances. The leverage ratio as measured by the Debt-to-Equity Ratio has no significant effect on financial distress. The liquidity ratio as measured by the Current Ratio has a significant positive effect on financial distress. In addition, the activity ratio as measured by Total Asset Turnover has a significant negative effect on financial distress. That is, the higher the total asset turnover of a company, the more un-healthy the company's financial condition will be. The inflation variable as measured by the Consumer Price Index has no significant effect on financial distress in companies in the trade, service and investment sectors during the 2018-2021 period
