In one of the Work Units, namely the Administration and Sales Department, there is one Fertilizer that rarely has income that does not meet the Company's RKAP Quantum Target, namely Urea fertilizer as evidenced by the Pre-Research results, Quantum Data Realization and Quantum Target RKAP Urea Fertilizer in 2021. In the research This analysis is carried out by analyzing customer perceptions and expectations using the Servqual Method to Measure Service Quality of the Urea Fertilizer Sales and Administration Department. Measurement results in finding the gap between Customer Perceptions and expectations from Servqual will be corrected with QFD. Then do the preparation of strategies that are applied to the Company. The results of Servqual show that all dimensions have a \"Unsatisfied\" Satisfaction Level, which means that the customer assesses that the service provided has not met the expectations of the customer. Next, an analysis is carried out using QFD which shows that the average of all attributes needs to be improved. Indicators that require Top Priority are those related to the Competence of the Urea PIC. So the recommendation from the AVP of Urea Fertilizer is to conduct a Procurement Evaluation of the Performance of the urea PIC at the Administration and Sales Department at PT.

Agar mampu bersaing, perusahaan jasa laundry harus mampu meningkatkan pelayanan dan memenuhi kebutuhan konsumen dengan sebaik mungkin. Salah satu perusahaan yang bergerak dalam bidang laundry yakni Simply Fresh Laundry 352 Tlogopojok Gresik dimana pada  proses laundrynya masih banyak dijumpai antrian pakaian yang terdapat pada sistem laundry. Untuk itu dilakukan analisis antrian agar mampu mengurangi jumlah antrian yang ada pada sistem. Salah satu metode yang dapat digunakan yaitu dengan melakukan analisis terhadap performansi dari sistem antrian yang terjadi pada proses laundry menggunakan model simulasi diskrit dengan bantuan software Arena. Tujuan dari penelitian ini adalah membuat model yang mampu menentukan jumlah fasilitas serta mengoptimalkan sistem layanan. Model usulan dikembangkan terkait dengan jumlah mesin dryer dan mesin cuci dari hasil analisis model awal dan aspirasi pemilik outlet. Hasil dari penelitian menunjukan bahwa model simulasi yang dibuat mampu memberikan gambaran performansi sistem laundry dengan diketahuinya nilai service level sebesar 96%, waktu tunggu rata-rata menunggu paling lama terdapat pada antrian dryer sebanyak 225,58 serta tingkat kesibukan mesin paling tinggi terjadi pada dryer 1 sebesar 96,38% dan dryer 2 sebanyak 95%. Selain itu, dari hasil usulan 1 menunjukan adanya penurunan waktu rata-rata menunggu pakaian pada antrian dryer sebesar 92% dan nilai service level yang naik hingga 4%.
