This study aims to create and analyze smart packaging indicators using methyl red and bromothymol blue solutions which apply to the avocado or other local fruits in Indonesia, especially in Southern Sulawesi. This research was conducted at the food processing laboratory by following several stages. The stages are; the solvent making with the addition of 5% NaOH, the soaking of each solution on filter papers (whatman no 1), then keeping it untouchable for 12 hours, rinsing and drying and implementing to smart packaging. The observation parameter is the indicator analysis used the colour index. The colour index value of methyl red solution pH 7.5 is in the 1st day 185 AU and in the 7th day 133 AU, pH 9.5 in the 1st day 190 AU and in the 7th day 130 AU, and pH 11.5 in the 1st day 195 AU and day the 7th AU. While the colour index value in bromothymol blue pH 7.5 solutions is in the 1st day 175 AU and in the 7th 130 AU, pH 9.5 in the 1st day 165 AU and in the 7th day 120 AU, and pH 11.5in the 1st day 160 AU and the 7th day of 123 AU. The best result of the colour change was methyl red solution with pH 11.5 based on the colour determination by using a digital microscope and analysed using Corel Drawx7 "Eyedropper Tool" software to be quantified.
