ABSTRAK
Pengendalian kualitas merupakan aktivitas teknik dan manajemen melalui pengukuran karakteristik kualitas dari output. Dalam melaksanakan pengendalian kualitas terdapat beberapa cara yang dapat dilakukan, yaitu salah satunya dengan menggunakan alat bantu SPC (Statistical Proses Control). SPC sendiri merupakan suatu pengukuran terhadap proses-proses yang terjadi untuk kemudian dilakukan suatu pemantauan agar dapat menghasilkan suatu produk yang berkualitas. Penelitian ini diperoleh dalam rangka mengidentifikasi ketidaksesuaian kualitas benih tomat. Maka hal tersebut dapat dilaksanakan dengan menggunakan alat bantu yaitu peta kendali, diagram pareto, diagram sebab akibat, dan kapabilitas proses. Berdasarkan pengamatan peta kendali kemurnian benih pada peta kendali X bar terdapat data yang keluar batas kendali dan tidak ada data yang keluar pada peta kendali R, dapat dikatakan bahwa belum terkendali secara statistikal. Adapun nilai kapabilitas proses sebesar 2,22, yang berarti proses dianggap mampu. Berdasarkan pengamatan peta kendali kadar air pada peta kendali X bar terdapat data yang keluar batas kendali dan tidak ada data yang keluar pada peta kendali R, dapat dikatakan bahwa belum terkendali secara statistikal. Adapun nilai kapabilitas proses sebesar 1,28, yang berarti proses dianggap mampu. Berdasarkan pengamatan peta kendali daya kecambah pada peta kendali np terdapat data yang keluar batas kendali, dapat dikatakan bahwa belum terkendali secara statistikal. Adapun nilai kapabilitas proses sebesar 0,97 atau sebesar 97% kemampuan untuk menghasilkan produk atau kecambah normal.
Kata Kunci : SPC (Statistical Process Control) , Peta Kendali, Kapabilitas Proses

ABSTRACT
Quality control is a technical and managerial activity through measurement of quality characteristics of output. In implementing quality control there are several ways that can be done, for the example one is using SPC (Statistical Process Control). SPC is a measurement of the processes that occur for then performed a monitoring in order to produce a quality product. This study was obtained in order to identify the non-conformity of the quality of tomato seeds. It can be done by using several tools, such like control chart, pareto diagram, cause and effect diagram, and process capability. Based on the control chart of the purity seed, there is data that out of control limits on the X bar control chart and there is no data that exit on the control chart R, it can be conclude that it has not been statistically controlled. The process capability value got 2.22, which means the process is considered capable. Based on the moisture control chart, there is data that out of control limits on the X bar control chart and there is no data that exit on the control chart R, it can be conclude that it has not been statistically controlled. The process capability value got 1.28, which means the process is considered capable. Based on the germination control chart, there are several data that out of control limits on the control chart np, it can be conclude that was not yet statistically controlled. The value of process capability got 0.97 or means by 97% ability to produce normal products or sprouts.
