Abstract. Raja Sere is one of the indigenous banana cultivars in Indonesia. This cultivar has a yellow color when ripen, small size and sweet taste. Traditionally, the growers market this banana cultivar to the market without any treatment to delay the ripening process. Banana fruits are commonly being harvested at the condition of hard green mature. At this condition of hard green mature, banana fruits can be stored for a long-term period. The objective of this study was to examine the effect of cold storage on the quality of raja sere banana that stored at 130 C. Banana fruits cultivar Raja Sere were harvested from local farmer field at the condition of hard green mature (about 14 weeks age after the flower bloom). Fifteen bunches of banana were stored in cold storage with a temperature of 13ºC for 0, 3, 6, 9, and 12 days, respectively. For the control, room temperature storage (280 C) was used. At a storage period, samples of banana fruits ripened in the ripening chamber by injecting 100 ppm of ethylene gas at 250 C for 24 hours. The quality parameters namely respiration rate, hardness, total soluble solids (TSS), change in color, and weight loss were measured. For those banana fruits stored at room temperature, the shelf-life of banana was only reached up to 6 days. For those banana fruits stored in cold storage, the condition of banana fruits was reached up to 12 days. After cold storage and ripening, the third day measurement was the optimal time for bananas to be consumed which indicated by the yellow color (lightness value = 68.51, a* = 4.74 and value b* = 62.63), TSS 24.30 ºBrix and hardness 0.48 kgf, weight loss about 7.53-16.45% and CO2 respiration rate of 100.37 mLCO2/ kg.h NONE UPT.
