    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.

    Production performance of KUB chicken with the inclusion of Lamtoro (Leucaena leucocephala) leaf flour in the feed
    (IOP Publishing, 2021-01-01) Tirajoh, Siska; Dominanto, Ghalih P.; Usman; Alberth, Alberth; Bakrie, B; IOP
    To reduce the feed cost in raising chickens it is necessary to find alternative feed sources. The feed ingredients must have relatively low prices, do not compete with human needs, and have abundant availability on location. The purpose of this study was to determine the performance of KUB chicken production with feed containing Lamtoro (Leucaena leucocephala) leaf flour (LLF). The study was conducted using 300 chickens aged 4 weeks, unsexed, which were allotted to 4 treatments, each with 5 replicates and 15 birds per replicate in a Completely Randomized Design. The treatments were in the form of a) T0: 0% LLF; b) T1: 3% LLF; c) T2: 5% LLF and d) T3: 7% LLF. The LLF was mixed with a basal feed in a mixture of concentrate, corn and bran. The study lasted for 6 weeks, i.e. until the chicken was 10 weeks old, with observations including daily weight gain (DWG), feed consumption, feed conversion ratio (FCR), and income over feed cost (IOFC). The results showed that the best performance of KUB chicken production was by the addition of 5% LLF in the feed, as it could increase the DWG value, reduce the FCR value and increase the IOFC value.
