Many factors cause why farmers do not have the ability to maintain their socio-economic life, mainly because it is difficult to obtain fresh funds, unavailability of production facilities and supporting factors such as fertilizers, superior seeds, counseling, and the low attention of local and central governments.Explorative and developmental research, which focuses on exploratory activities in providing an overview in mapping the profile of farmers, including the supply chain of vegetables sold to the capital city of Palu, the capital city of Central Sulawesi Province as well as a trading center and government. The research was carried out around the areas affected by the Jono Oge and Sidondo Earthquake and Liquefaction of Sigi Regency to look at the marketing chain and Palu City to see the supply chain at the Masomba and Manonda traditional markets, while to see the perpetrators of the trade system were traced based on the location of the traders and suppliers domiciled. To find out the suppliers in the traditional market, a careful identification is carried out so that the percentage (share) of suppliers outside Jono Oge can be known.The data analysis used in this research is descriptive.The longer the marketing chain in the tomato and chili vegetable trading system in the research area around Jono Oge and Sidondo which was affected by the earthquake and liquefaction, the more inefficient it will be. Thus, marketing channel I for both tomatoes and chilies is the one that gives a higher Farmer’s Share value and is more efficient than marketing channel II. All institutions involved in the marketing chain, from farmers, traders to retailers, carry out marketing functions, namely buying, selling, transportation, storage, processing, standardization and grading, financing, risk management, and market information. The margin share of producer farmers in each marketing channel for each tomato and chili is 84% and 89.74%, respectively.
