Abstract
Sweet potato-pigs integration system (hipere-wam) is a model that farmer can apply to
maintain production in highland area. The aim of this study is to produce a specific location model
of sweet potato-pigs integration technology in the sweet potato center area. The results of the study
show that sweet potato production during the four months of the assessment with the wet tuber
weight for Musan cultivar was 0.90 kg/ plant or 21.67 t/ha and Cangkuang cultivar was 1.06
kg/plant or 25.47 t/ha, respectively. Biomass production was 0.84 kg/plant or 20.24 t/ha for Musan
cultivar and 0.76 kg/plant or 18.31 t/ha for Cangkuang cultivar, respectively. The increase in the
body weight of introduced pigs was 157 g/head/day, compared to the farmer's which was of 50
g/head/day. Based on the calculation of the level of consumption of pigs during the assessment, it
shows that the average feed requirement from sweet potato was 1.5 kg /head/day or 180 kg /head /4
months or 2.880 kg/16 heads/4 months. The calculation of organic fertilizer from wet livestock
manure for four months of maintenance was 480 kg or 30.0 kg/head or 0.30 kg/head/day. If it is
assumed that 0.065-0.066 hectare land contains 1.733-1.760 plants, the contribution of organic
fertilizer from pig manure to sweet potato plants is 130 - 140 g/plant/4 months.
