PT. XYZ merupakan perusahaan yang bergerak di bidang pengolahan kelapa sawit. Di dalam pengolahan dari CPO menjadi minyak Refined Bleached Deodorized Palm Oil, tentunya tidak lepas dari masalah yang berhubungan dengan kualitas. Penelitian terhadap kualitas Refined Bleached Deodorized Palm Oil dilakukan dengan menggunakan Metode Taguchi. Tujuan dari metode Taguchi ini yaitu untuk menentukan kombinasi level yang optimal untuk masing-masing faktor sehingga dihasilkan Refined Bleached Deodorized Palm Oil yang sesuai dengan standar. Hasil analisa diolah dengan menggunakan metode rata-rata, analisis varians dan strategi pooling up. Dari hasil kesimpulan menunjukkan bahwa untuk kadar ALB setting yang paling optimal yaitu tekanan perebusan pada level 1 (2,0 torr), temperatur perebusan pada level 2 (105oC) dan waktu pada proses perebusan pada level 1 (50 min). Untuk kadar warna setting yang paling optimal yaitu tekanan perebusan pada level 1 (2,0 torr), temperatur perebusan pada level 2 (105oC) dan waktu pada proses perebusan pada level 1 (50 min). Sedangkan untuk kadar air setting yang paling optimal yaitu waktu pada proses perebusan pada level 2 (60 min), temperatur perebusan pada level 2 (105oC) dan tekanan pada perebusan (2,0 torr). Berdasarkan data di atas, dapat diketahui bahwa total proporsi cacat secara keseluruhan setelah diterapkan kombinasi setting yang optimal berdasarkan penelitian dengan metode Taguchi adalah 18,05%. Setelah menerapkan kombinasi setting yang optimal berdasarkan metode Taguchi, total proporsi cacat secara keseluruhan menurun sebesar 9,71%.

Satisfaction is a person's feeling of pleasure or disappointment after comparing the performance (results) of the product thought to the expected performance (work performance). If the performance is under expectations, it means the customer is not satisfied; vice versa, it will cause the patient to lose interest in seeking treatment. To find out the priority level in improving the quality of clinical patient services, it used the Potential Gain in Customer Value (PGCV) method. Then, to identify dimensions of service quality, it used the Importance Performance Analysis (IPA) method. The data collected in this study were by conducting surveys, distributing questionnaires, and interviewing. The result of the servqual score was negative, with the largest gap score in the attribute (Responsiveness 1)-Affordable inspection fees, and the attribute (Emphaty3)-Nurse was always there when the patient called or needed with a score of -1.73333. The attribute Responsiveness 1 (Affordable examination fee) with the largest PGCV index score of 10.9333. The second priority that had to be improved with the PGCV index score was 10.69445. The attribute Rb3 (Take action according to the procedure) was the third-highest priority that had to be improved with a PGCV index score of 10.166667.
