Analisis Pengendalian Mutu Crude Palm Oil (CPO) dan Palm Kernel (PK) Menggunakan Metode Analisis of Variance (Anova) di PMKS PT. Sinar Gunung Sawit Raya Sirandorung

Abstract

PT. Sinar Gunung Sawit Raya Sirandorung adalah perusahaan yang bergerak dalam bidang perkebunan dan penghasil produk minyak sawit mentah. Tujuan penelitian ini adalah untuk mengetahui data yang keluar dari batas kontrol dengan menggunakan SQC dan mengetahui variansi yang mempengaruhi kualitas CPO dan inti sawit dengan menggunakan Anova. Berdasarkan hasil pengolahan data menggunakan SQC ada data yang menyimpang dari batas kontrol yaitu kadar ALB yang tinggi pada bulan Februari sebesar 3,7% dan bulan Juni sebesar 1,98%. Dari hasil Anova nilai Fh untuk kadar ALB: 10,56 > F0,01;3;44 : 4,26 maka Ho ditolak adanya pengaruh kadar ALB terhadap kualitas CPO. Nilai Fh untuk kadar air: 0,08 < F0,01;3;44 : 4,26 maka Ho diterima tidak ada pengaruh kadar air terhadap kualitas mutu CPO. Nilai Fh untuk kadar kotoran: 28,18 > F0,01;3;44 : 4,26 maka Ho ditolak adanya pengaruh kadar kotoran terhadap kualitas mutu CPO. Dari hasil Anova inti sawit nilai Fh untuk kadar ALB: 0,88 < F0,01;3;44 : 4,26 maka Ho diterima tidak ada pengaruh kadar ALB terhadap kualitas mutu inti sawit. Nilai Fh untuk kadar air: 12,88 > F0,01;3;44 : 4,26 maka Ho ditolak adanya pengaruh kadar air terhadap kualitas mutu inti sawit. Nilai Fh untuk kadar kotoran 28,17 > Ft 4,26 maka Ho ditolak adanya pengaruh kadar kotoran terhadap kualitas inti sawit. Perbaikan untuk tingginya kadar ALB dapat dilakukan dengan membuat SOP penerimaan TBS, sehingga mutu TBS yang diterima sudah standar. PT. Sinar Gunung Sawit Raya Sirandorung is a company in the plantation sector that produces crude palm oil products. This study aimed to know the data that was out of control limits using SQC and to find the variance that affected the quality ofCPO and palm kernel using ANOVA. Based on the data processing using SQC, some data deviated from the control limits, namely high ALB levels in February of 3.7% and in June of 1.98%. From the ANOVA results of the Fh value for ALB content:10.56 > F0.01;3;44 :4.26, Ho was rejected because of the effect of ALB content on CPO quality. The Fh value for water content: was 0.08<F0.01;3:44:4.26 so Ho accepted that there was no effect of water content on the quality of CPO. The Fh value for dirt content: was 28.18 > F0.01;3;44 : 4.26 so Ho was rejected due to the influence of dirt content on the quality of CPO. From the results of the ANOVA palm kemel, the Fh value for ALB content was: 0.88 < F0.01;3;44 :4.26 so Ho accepted that there was no effect of ALB content on the palm kernel quality. The Fh value for water content was: 12.88 > Fo.01:3:44:4.26 so Ho was rejected due to the influence of water content on the palm kernel quality. The Fh value for dirt content was 28.17 > F, 4.26 then Ho was rejected due to the influence of dirt content on the palm kernel quality. The improvements for high levels of ALB could be performed by making SOPs for receiving Fresh Fruit Bunches (FFB) so that the quality of FFB received was standard.
