From the language you used in your profile, I figure you may be living in Indonesia. There is a website called www. fincyte. com/ small business ideas in Indonesia with two articles (or more), one with the title: “16 Profitable Small Business Ideas in Indonesia in 2020” (Nov 2019), and another with the title: “7 Easy Steps for Starting a Small Business” (April, 2016).
Before you invest in a business, do a thorough research and consult with reliable people who have experience in the business you are interested in starting. Research enough so that you can have realistic expectations regarding the risks involved, the investment required over time (money, time and effort), and regarding when to expect any profit from the business (many businesses take months before experiencing profit).
