Chili is one of horticultural products that is easily damaged. The damages occurs due to
physical, chemical, microbiological and physiological influences. Chili fresh’s handling in Indonesia is relatively simple, careless, less handling facilities provided and minimal
information obtained by farmers and in addition, because of the influence from the environment, the loss is usually high. Thus, a proper postharvest technologies needed to reduce damaged of fresh chili, maintain their freshness and increase the price of products. One of post-harvest handling technology that is applicable is ozonation technology. Ozone is known to control pathogenic microorganisms and able to remove metals and pesticide residues. The study was conducted in Sungai Belida village, Lempuing Jaya, Ogan Komering Ilir (OKI) district of South Sumatera and South Sumaetra AIAT’s Laboratory, from June to August 2016. The treatment tested 37.5 ppm ozone application and farmer practice (spraying fungicide day before harvest)
and performed at 4 farmers as replication. Harvested chilies then taken to the Laboratory of BPTP South Sumatra for observation. Data collected include changes in weight loss and moisture content, observation on anthracnose intensity to chilies and pesticide residues. The results showed that ozon technology able to minimize weight loss, damage caused by anthracnose and pesticide residues in fruit chili. In addition, this technology can be accepted by farmers because it is easy to apply. However, as the economy needed additional labor costs and to apply this technology.
