ABSTRAK

Pupuk merupakan bahanmaterial atau unsur hara yang ditambahkan ke dalam tanah dan tumbuhan baik berupa pupuk organik maupun pupuk anorganik dengan tujuan untuk memenuhi atau melengkapi keadaan unsur hara dalam tanah yang tidak cukup tersedia untuk memenuhi kebutuhan tanaman. Oleh karena itu dalam membuat pupuk yang berkualitas diperlukan banyak teknik dan praktik mengenai jaminan kualitas agar produk sesuai dengan spesifikasi yang diharapkan. Salah satu cara untuk mengontrol kualitas produk adalah melakukan pengendalian kualitas dan menjaga kapabilitas prosesnya. PT.Petrokimia Gresik merupakan perusahaan yang bergerak dalam bidang pembuatan pupuk salah satu produk yang dihasilkan adalah pupuk jenis ZK. Pupuk tersebut memiliki lima karakteristik kualitas yaitu H2O Kadar Air K2O Kalium SO3 Sulfur H2SO4 dan CL-. Penelitian ini bertujuan untuk mengetahui kualitas pupuk jenis ZK dalam keadaan terkendali atau tidak dan seberapa besar kapabilitas prosesnya. Berdasarkan analisis yang telah dilakukan diketahui bahwa proses produksi filter super slim jenis mono sudah terkendali dalam rata-rata dan varian. Hasil kapabilitas proses perbulannya untuk bulan Oktober 2013 sebesar 194164 November 2013 0785709 dan Desember sebesar 107765 yang artinya proses produksi berjalan dengan baik dan sebaran data berada didalam batas spesifikasi perusahaan kecuali pada Bulan November perlu di adakan perbaikan agar proses produksi berjalan dengan baik pada bulan tersebut dan bulan-bulan selanjutnya.

The fertilizer has five quality characteristics namely H2O Water Content K2O potassium SO3 sulfur H2SO4 and CL-. This study aims to determine the quality of the fertilizer type ZK under controlled conditions or not and how much capability the process. Based on the analysis conducted it is known that a super-slim mono type production process is under control in mean and variance. The result of process capability per month for the month of October 2013 was 1.94164 0.785709 November 2013 and December at 1.07765 which means that the production process runs well and distribution of the data are within the specification limits the company except in November needs some improvements to production process goes well for the month and the following months.
