Penelitian ini bertujuan untuk mengetahui pengaruh penambahan natrium benzoat dan minyak jahe(Zingiber officinale) sebagai bahan pengawet terhadap kualitas ikan tuna (Thunnus sp) kaleng. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) pola faktorial yang terdiri atas 2 faktor. Faktor I adalah konsentrasi bahan pengawet dari pengawet alami dan pengawet non alami (K), yang terdiri atas (K1) Kontrol, (K2) Natrium Benzoat 0,1%,(K3) Minyak Jahe 5%; (K4) Minyak Jahe 10%, dan (K5) Minyak Jahe 15%. Lama penyimpanan (L) terdiri (L1) 0 minggu, (L2) 2 minggu, (L3) 4 minggu, (L4) 6 minggu, dan(L5) 8 minggu. Hasil penelitian menunjukkan bahwa interaksi penambahan bahan pengawet  dan  lama  penyimpanan  berpengaruh  sangat  nyata  terhadap  total mikroba. Total mikroba pada ikan tuna kaleng selama penyimpanan semakin berkurang  dengan  semakin  tinggi  konsentrasi  minyak  jahe  yang  digunakan sebagai pengawet alami. Lama penyimpanan berpengaruh sangat nyata terhadap jumlah kadar air , kadar abu, dan kadar lemak pada ikan tuna kaleng. Berdasarkan uji hedonik warna, aroma, tekstur dan rasa ikan tuna kaleng, panelis cenderung menyukai ikan tuna kaleng dengan penambahan minyak jahe dengan konsentrasi&#13;
10% dan 15%.&#13;

ABSTRACT&#13;
&#13;
&#13;
&#13;
The study aimed to determine the effect of sodium benzoate and ginger oil (Zingiber officinale) as a preservative to maintain the quality of the canned tuna (Thunnus sp). The study used a randomized block design consisting of two factors. As the main factor was the concentration of preservative both from natural and non-natural  materials  (K),  consisting  of  (K1)  Control,  (K2)  Sodium  Benzoate&#13;
0.1%, (K3) Ginger Oil 5%, (K4) Ginger Oil 10%, and (K5) Ginger Oil 15%. The&#13;
storage duration (L), consisting of (L1) 0 weeks,(L2) 2 weeks,(L3) 4 weeks, (L4) 6&#13;
weeks,and (L5) 8 weeks. The results showed the significant interaction between&#13;
preservatives and storage durationwith respect to total microbial. The amount of&#13;
microbial in the canned tuna decreased along with the addition of ginger oil. Storage duration contributed to very significant effect on the amount of moisture, fat and ash contents.Meanwhile, according to hedonic testing, color, aroma, texture and taste of canned tuna, the addition of ginger oil about 10% and 15%, tend the panelist give higher score (like).&#13;
