Banana is one of several Indonesian agricultural commodities which has a important economic potential either in the local and international markets. There is an increase in banana producbon in Jndonesia especiaUy ihe cavendish variety. Jn Mojoke o, East Java, it has been developed about 1000 Ha of cavendish banana ptantation. One of the main .problem of fresh banana market is short storage life due to its climacterical respiration process. Therefore the objective of these research were to find 1) optimum storage temperature, 2) optimum ratio ofOzand C02, 3} type of modifled atmosphere, 4) suitable packaging material, 5) appropriate hormone to delay ripening and 6) maximum storage life of banana. The banana used in these experiment were selected from 90 days after .flower~ng harv~st from Santur .Plantation of Southern Malang. Experiment on the storage temperature showed that storing at 14°C could decrease respiration rate, weight loss and its hardness compared to 10, 18, 22°C and room temperature (26°C). Respiration rate at 14°C was 0.93 ml/kg/hr. Area of modified atmosphere (MA) for banana storage was 1 to 4 percent of 0 2 and 4 to 7 percent of C02. This area of modified atmosphere could reduce the incrense of reduction sugar content, weight loss and colour score of banana. Banana stored in these conditions contained 1.72 percent reduction sugar having colour score of 2.09, texture of 46.50 x 10-4 mm/g/sec and weight loss of 1.15 percent only. The .best packaging materrel for banana storage was low density polyethylene. This type of packaging could reduce respiration process which was shown by preventing green colour of banana peel (score of 2.16). Low reduction sugar (3.11 percent}, weight loss of 3.16 percent and -hard texture -of 50.30 x 10-4 mm/g/sec were also shown by this stored banana. Soaking in 2 ppm of benzyladenine (BA) solution for 3 minutes could prolong the storage hfe of banana compared to other chemical treatment. • Therefore, banana treatment with 2 ppm BA and stored at 14°C in the area MA of 1 to 4 percent 0 2 and 4 to 7 percent C02 and packed with low density polyethylene could .prolonged 1ts storafW me up to 42 days without any damages
