.....so why don't you?
Well, the poultry, fish, cooking oil, tomatoes, chili, spinach, beef jerky (dendeng sapi), salted fish (ikan asin) have been helping my family to survive these past few years.
If you see my Linkedin profile and wonder how much my salary was with my previous job, I earned around USD750/month, while the cost of living keeps climbing up. So we practically live from paycheck to paycheck, and without a side income, my family will barely survive.
The methane gas needs a sufficient amount of manure, which means I need to have a good amount of cattle and a vast land to graze which I don't have.
Back in the '80s our minister of technology, B.J.Habibie, started a pilot project to have rural areas to use solar energy but it was stopped because a family member of our previous president established a private company with Payton Power and sell the electricity to government owned power company (PLN) which makes the power bill swell quite significantly.
Solar panels and wind generators are quite expensive and must be imported directly, while the import tax and custom clearance cost is very high.
So, some of it is still a dream, and it is hard to find a good barley supply to brew your own beer.
