SUMMARY
ANITA WIDYARMI. The Effect of Lime and Additive Protein Application to
Sheep Manure as Compost Substance on Vermicompost Quality and Earthworm
Biomass (Supervised by DWI PUTRO TEJO BASKORO and KAMIR R.
BRATA).
Decreasing of organic matter is the main cause of the decreased in physical,
chemical and soil biologic condition, so that the land productivity also decreased. The
decreased in organic matter can be pushed by adding organic matter into the soil
using any kind of waste, such as plants, manure, etc. One of them is sheep manure.
Using sheep manure to return soil organic matter in raw condition give a negative
effect on plant. Because of that, sheep manure needs to be composted.
Vermicomposting is a perfection of much organic waste composting
technique with biotechnology, or organic waste composting with earthworm.
Vermicomposting has a good prospect; beside result a very high nutrient compost,
also earthworm that have a variety of usefulness and high economic value.
The purpose of this research is to learn about the effect of lime and additive
protein (leaves of Gliricidia maculata (H.B.K) and soybean curd sludge (SCS))
application to sheep manure as compost substance on vermicompost quality and
earthworm biomass.
This research was conducted in physic and soil conservation laboratory, Soil
Science, Faculty of Agriculture, Bogor Agriculture University, from April to August
2000. Analysis of physical, chemical and vermicompost biological were conducted in
physic and soil conservation laboratory, student laboratory, and soil biology
laboratory, Soil Science, Faculty of Agriculture, Bogor Agriculture University.

This research used completely randomize designed experiment with 10
treatments, there are KOAO (without lime + without protein), KOAl (without lime +
5% of soybean curd sludge (SCS)), KOA2 (without lime + 10% of soybean curd
sludge (SCS)), KOGl (without lime + 5% of Gliricidia sp. leaves), KOG2 (without
lime
+
10% of
Gliricidia sp. leaves), KlAO (1% of lime
+
without protein),
KIAl(l% of lime + 5% of soybean curd sludge (SCS)), KIA2 (1% of lime + 10% of
soybean curd sludge (SCS)), KlGl (1% of lime + 5% of Gliricidia sp. leaves) and
K1G2 (1% of lime
+
10% of Gliricidia sp. leaves), with 3 repetition of each
treatment, so there were 30 sets of experiments.
Observation and measurement were assigned on vermicompost dry weight
and earthworm biomass, vermicompost chemical characteristics (Total-N, Organic-C,
exchangeable Potassium, exchangeable Calcium, exchangeable Magnesium, CEC,
available P and pH), vermicompost physical characteristic (available water) and
biological characteristic (respiration rate).
The result showed that earthworm weight is increasing with application of
Gliricidia sp. leaves and soybean curd sludge (SCS), weather with lime or not. The
increased of earthworm biomass is higher in application soybean curd sludge (SCS)
compare to Gliricidia sp. leaves, and also higher in lime application compare to
treatment without lime. The application of Gliricidia sp. leaves and soybean curd
sludge (SCS) on treatment with or without lime, also increased vermicompost dry
weight, with the higher increased on Gliricidia sp. leaves.
The application of Gliricidia sp. leaves, soybean curd sludge (SCS) and lime
increased Total- N of vermicompost. The increase of Total-N is higher on Gliricidia
sp. leaves application, compared to soybean curd sludge (SCS), and also higher on
lime application to without lime. Application of Gliricidia sp. leaves, soybean curd
sludge (SCS) and lime decreased the C/N ratio of vermicompost. Application of lime
increased vermicompost exchangeable K and Ca. On treatment without lime, is
decreasing the vermicompost CEC, although the decreased is not significant, when
Gliricidia sp. leaves have increased vermicompost CEC. On lime treatment, soybean
curd sludge (SCS) and Gliricidia sp. leaves have increased vermicompost CEC.
Application of Gliricidia sp. leaves, soybean curd sludge (SCS) and lime have no
significant effect on Organic-C, available P, Exchangeable Magnesium, pH, available
water and respiration rate of vermicompost.
