Incorrect post-harvest handling of shallots (Allium ascalonicum L.) can result in damage in the form of shoots, rot, and hollowness. By producing the right postharvest technology, the production of shallots can be saved because the damage can be suppressed, one among them being in-store dryers. The implementation of in-store dryers in Solok Regency is one of the efforts to accelerate replication in the community. In addition, several processed shallot products have also been developed, including whole shallots in brine, shallot paste, dried sliced shallots, shallot flour, and fried shallots. The in-store dryer was built at the onion advanced farmer group, which is in Lembah Gumanti District, Solok Regency has a geographical condition of 930 m asl and 7,409 mm of rainfall. The in-store dryer production test has been carried out twice, respectively 3.25 and 10.8 tons, which requires a drying time of 6–7 days, much shorter than the traditional method. The yield of shallots ranged from 60–68.9% with a fairly good quality of shallots. There were no rotten and empty shallots, while the sprouted shallots were about 0.1– bank interest), B/C ratio of 1.03, and Pay Back Period of 1.6 years.
