Abstract

Kajian laboratorium ini dilakukan untuk mengetahui mekanisme pengaruh negatif hujan asam terhadap makrofauna tanah. Armadillidium vulgare yang merupakan salah satu makrofauna tanah pemakan seresah (saprofag) penting di Tokyo yang digunakan dalam penelitian ini. Pengaruh makanan, pengaruh langsung dan pengaruh medium yang direndam dengan cairan asam digunakan untuk mengetahui mekanisme ini. (1). Pengaruh makanan dilakukan dengan cara merendam seresah daun aoki (Aucuba japonica) dalam air atau air yang diberi cairan H2SO4 dengan pH 6,4, dan 2. Seresah ini diberikan pada A. vulgare sebagai makanan (2) Efek langsung dilakukan dengan cara meneteskan 1 ml air atau air yang diberi cairan H2SO4 langsung ke tubuh hewan setiap dua minggu. (3) Pengaruh medium dilakukan dengan merendam medium dalam air maupun air yang diberi cairan H2SO4. Pertumbuhan dan persen hidup A. vulgare dicatat. Pertumbuhan dan persen hidup A. vulgare yang diberi makan seresah yang rendam dalam larutan asam sangat rendah. Penetesan cairan asam pada tubuh A. vulgare secara langsung tidak berpengaruh negatif terhadap pertumbuhan dan persen hidup A. vulgare. Pertumbuhan A. vulgare tidak dipengaruhi oleh medium yang direndam dalam cairan asam, tetapi persen hidupnya sedikit berkurang. Pengaruh cairan asam secara tidak langsung melalui makanan lebih penting daripada pengaruh langsung. Hal ini disebabkan tubuh A. vulgare dilindungi kutikula yang tebal. Untuk taksa yang memiliki tubuh yang lunak pengaruh langsung mungkin juga penting.

Abstract

Earthworms feed exclusively on dead organic matter (OM). The earthworm population is regulated by organic matter availability and soil characteristics. The aim of the research was to investigate the effect of seasonal change to the abundance and biomass of earthworms in Wanagama I. Collection of the soil samples was conducted from a quadrangle 25 x 25x 25 cm with the depth of 0-10, 10-20 and 20-30 cm with 5 replications under stands of Glyricidae, Leucaena, Teak, Acacia, Eucalyptus and Mahogany. Soil samples were taken at rainy season (February), early dry season (July) and dry season (October) 2004. The earthworms were manually extracted from soil samples and the abundance was stated as number and biomass of dry weight. The result showed the abundance and biomass of earthworms were high only in February at the soil depth of 0-10 cm. The highest number of earthworm and biomass was found in Mahogany stand (224,000 individual.ha-1/105.6 kg.ha-1). Multiple linier regression analysis showed that abundance of earthworms was affected by soil moisture content, while the biomass of earthworms was affected by soil pH and bulk density (aeration).

This study identified two themes in his research consisted of planting the value of strong character through a social skills program, and implantation on the character concerned with social skills program. Two themes are based on research goals predetermined and interconnected to form a theory of value investment of strong character and care.
