is a subsidiary of PT. Adhi Karya (persero) tbk, which produces precast concrete, including spun pile. There was a problem in spun pile production; the average percentage of spun pile defects was 0.71%, exceeding the company standard, which was 0.5%. Therefore, this research was conducted to analyze the defect and provide improvement proposals to reduce the defective products. Five dominant defects that occurred were fin, chipped, sticky skin, curved, and broken. Based on the Spun Pile production process analysis, the DPMO of 617, and sigma level value of 4.73. Based on these criteria, the improvement proposal will be evaluated. The apriori algorithm indicated two defects have a strong combination relationship; they are Curved and Sticky Skin. Another defect prioritized to solve is Fin, the second-highest RPN from FMEA analysis. The use of rust remover can make the improvement proposal given to overcome fin defects. The use of mold cleaning forms is to overcome sticky skin and curved caused by unhardened concrete using a Thermocouple on steaming tubs. This research can only be carried out until the improvement stage because the proposed improvements cannot be implemented due to the lockdown situation at the factory.
<p><em>Pengembangan e-commerce untuk pemasaran produk UKM (Usaha Kecil Menengah) telah banyak dilakukan di Indonesia. Beberapa e-commerce telah dikembangkan oleh Pemerintah namun masih belum mampu meningkatkan penjualan produk UKM di daerah. E-commerce Produk UKM harus mampu bersaing dengan e-commerce lain yang sudah berhasil di pasaran.

Tujuan dari penelitian ini adalah untuk mengetahui posisi e-commerce produk UKM berdasarkan pendekatan kualitas afektif e-commerce. Multidimensional Scaling (MDS) digunakan untuk memetakan posisi e-commerce produk UKM dalam persaingan e-commerce di Indonesia. Hasil ekstraksi Kansei Words menggunakan Term Frequency Inverse Document Frequency (TF-IDF) dan Principal Component Analysis (PCA) adalah dua kata kansei (canggih dan terjangkau). Kedua kata ini digunakan untuk analisis posisi sebagai dimensi peta perseptual. Berdasarkan peta perseptual, e-commerces produk UKM sudah canggih tetapi tidak cukup terjangkau.</em></p>
