Growth and reproduction studies were carried out in the mixture of cow dung (CD) and POMS. The result of the study showed the highest growth was in 60% POMS + 40% CD followed by 40% POMS + 60% CD, 20% POMS + 80% CD, 100% CD, 80% POMS + 20% CD with maximum individual weight raised to 1210.67 10.07 mg/earthworm, 1116.67 5.77 mg/earthworm, 1036.67 64.29 mg/earthworm, 980.00 2.0 mg/earthworm, 699.33 8.08 mg/earthworm respectively. The relative growth rate was determined through the slopeof straight-line regression of the log phase of the growth profile. The highest relative growth rate was in the mixture of 60% POMS + 40% CD and 40% POMS + 60% CD which are significantly different (P<0.05) with the rate of 183.38 mg/week and 170.53 mg/week respectively. The relative growth rate decreased in 80% POMS + 20% CD followed by 20% POMS + 80% CD and 100% CD with the rate of 127.42 mg/week, 116.07 mg/week and 97.90 mg/week respectively. Experiment on reproduction was carried out through determination of cocoon production along the study process. The result showed that the highest cocoon production was in 20% POMS + 80% CD (67 cocoons) followed by 40% POMS + 60% CD (66 cocoons), 100% CD (64 cocoons), 60% POMS + 40% CD (49 cocoons) and 80% POMS + 20% CD (18 cocoons). No growth occurred for the worms in 100% POMS, where mortality occurred starting from the first week until 100% mortality on week 4. Although the highest growth rate and maximum body weight were achieved in 60% POMS + 40% CD, the cocoon production was low. Nevertheless, the mixture of 60% POMS + 40% CD has been chosen as the most efficient for vermicomposting process of POMS. Study of vermistabilization process has been carried out using the mixture of 60% POMS + 40% CD which was labeled as POMSCD1. The mixture underwent pre-treatment for 14 days and was labeled as POMSCD2. The result showed, the pH of POMSCD2 shifted from 7.5 to 7.0 after the vermicomposting process for 14 weeks. At the same time the organic matter also decreased from 69.17 0.32% to 29.14 0.44%, the carbon to nitrogen ratio also decreased from 38.38 to 14.44. Phytotoxicity also decreased after vermicomposting with the increase of germination index from 14% in POMSCD2 to 88%89% in each vermicomposting replicate. Meanwhile the content of macronutrient and micronutrient such as potassium, sodium, calcium, iron, zinc and copper just had small changes. The metals that have a clear increment were magnesium and manganese. As a result, it is proved that earthworm, Eisenia fetida successfully stabilized palm oil mill effluent sludge (POMS)</p> 2012 thesis https://ir.upsi.edu.my/detailsg.php?det=12280 https://ir.upsi.edu.my/detailsg.php?det=12280 text eng N/A openAccess Masters Perpustakaan Tuanku Bainun Fakulti Sains dan Matematik N/A |
