Produce Food and Feed of Cereals Legumes and Root Crops in Tropical Agro-forestry of Java Indonesia

Approximately 61% of Indonesian live in Java, which the area only around 7% of the country. As part of global community, Indonesia has strong endeavor to realize Millennium Development Goals (MDGs) which put a top priority to reduce hunger and alleviate poverty till 50% at 2045. Unfortunately, the severe of global warming locked a dream into a reality. Praxis of past and present food crops production in forest area of Java, indicate that Java able to feed not only domestic dweller, but also outer island and even abroad. Unfortunately during to food crops production practices there is detrimental effect to forest, so basic function as carbon sink is disturb. Forest area of Java is 3.3 million ha only around 2.5% from Indonesian forest. Around 73% of Java forest managed by Perhutani (State Forest Enterprise), and of 27% remaining maintained by civilian. The lethal dose of cyanide for human was reported to be 0.5-3.5 mg HCN/kg body weight, which was about 30-210 mg HCN for a 60 kg adult. the content of HCN at the bitter cassava genotypes is above than 50 mg/kg fresh of root. Cassava very bitter genotypes may consist of HCN above than 100 mg/kg fresh weight of root. During hunger calamity people in rural community consumed cassava without considering the HCN content, as a consequence toxicity of cassava to be serious problem which induces to passing away. Indeed, the human body is able to detoxify as high as 100 mg of HCN for 24 hours by rapid conversion of cyanide into the much less toxic thiocyanate, which is then excreted in the urine. Porang as Elephant Food Yam or conyac (Amorphophallus muelleri Blume) was very popular food in Perhutani forest, they eat at of under teak forest. However, porang was very popular in cassava, sweet potato and root crops in famine calamity in 1945 to1980. Porang was sold in Pasuruan 1980 by PT. Ambico. 2020 as Shirataki noodle in Japan. Porang is high glucomannan, purification of glucomannan is conducted on porang which has been dried and made flour. Soybean is highly protein 34% of tofu and tempe, they very suitable due to cheapest in protein. Apart of cereal and grain legumes which more recognize as food source, shade tolerant root-crops have a significant advantage from its ability to produce more food in a form of starchy roots under greener environment. Future progress of agro-forestry should be able to keep greener forest as carbon sink in line with providing food sufficiently for dwellers.
