Abstract

Population growth and activity progress of the city need area to support its life and consequently there will be very tight competition among individuals or groups in using the land. The need of land for residence, industry or service has annexed the farmland and converts it intensively and massively. Population growth will increase the need of land. Unproductive land especially the farmland will be converted, and the conversion of the farmland will cause the change of carrying capacity. Carrying capacity has a certain capacity. Population growth will increase consumption of sourcing. On the other hand, the conversion of farmland will decrease carrying capacity. Carrying capacity is the total bio capacity divided by total ecological footprint. Knowing the conversion of farmland for bio capacity and ecological footprint in the suburb of Semarang city is the purpose of this research. Resources consumption per capita is called ecological footprint with global hectare (gha). The conversion of of farmland will change the use of farmland. Of course this will give impact on the carrying capacity. Carrying capacity in this case is from the farming products and green open spaces. Analytic descriptive method is applied for this research with the population is the agriculture area and total inhabitants in the suburb of Semarang city which consist of the district of Gunungpati, Mijen and Tugu. The districts are chosen because there were many area conversions and a rapid population growth from the year of 2000 to 2015. The main variable of this research comprises agriculture area, total population, inhabitant increase and carrying capacity. The result of this research show that there is significant effects of decreasing farmland on agriculture product and green open space. This condition will influence food self-sufficiency that will increase food deficit and grow food import from other area. The carrying capacity of Semarang is 0,19 from 0 to 1. It shows a critical condition. The decrease in agriculture area will influence the green open space as a water absorption and city green area. Research result shows that decreasing farmland area will have a big impact on the decrease in the carrying capacity. It is suggested that the government control the conversion of agriculture area with a strict regulation.
