Abstract

The more population grows, the more the food demand required. In this case, soybean, due to the less production compared to rice. In order to support food self-sufficiency and soybean demands, tropical legumes are cultivated due to its nutritional content which is similar to soybean. The local Indonesian plant, jack bean has adaptive properties to sub-optimal land. It can adapt to various cultivation systems, high productivity, and similarity of nutritional content to soybean. It has quite unique adaptations which can grow its upright stems or grows vines, depends to the environment, and relatively shorter age than another type local bean plants. Jack bean seeds can be further processed into tempeh, powder, bakpia (Indonesian traditional sweet cake which using nuts for the filling), and various cakes as a substitute for soybean, mung bean, and wheat. Therefore, the jack bean plant has a great potential as food self-sufficient Indonesia’s program.

Highlights

In 2015, Indonesia had 251 million populations, and it increased to 267 million in 2019
Started in 2014, local soybean was produced until 954.997 million tons per year [2], 332 thousand tons soybean was produced outside Java and 622 thousand tons produced in Java
To increase food productivity on marginal lands requires policy support and commitment from the government, both central and regional as well as farming communities [6]. [12] reported that the cultivation of jack bean reaches 4.53 tons per ha, as well as [13] reported that the treatment of plant by trimming the shoots and giving various concentrations of liquid organic fertilizer has a productivity of 3.9 - 4.6 tons per ha

Summary

Introduction

In 2015, Indonesia had 251 million populations, and it increased to 267 million in 2019. One of the crop that has potential as food sufficiency support is soybean. Indonesia had imported soybean to fill the demand, and divided into 3 categories: for agriculture seed is 2.088 million tons, for food raw-source is 2.393 million tonnes, and soybean oil is 1.971 million tons. The increasing demand for soybean is not proportionally suitable between land productivity and demands, it is necessary to find alternative commodities that have nutritional value as a soybean substitute.
