The aims of this are to find out: 1) The air pollution level a result of the diesel energy source activity. 2) the noise level as a result of the diesel energy source activity. The research was conducted in PLTD Kota Bitung Propinsi Sulawesi Utara. The data was colected from February to June 1999.

Biology reductions of coffee residue, waste from PT. Torabika industry, Tangerang using earthworm have been carried out. The aim of experiment is to know the ability of earthworm to decompose the waste become verrnicompost and to evaluate it quality. The experiment was used earthworms Eisenia foetida species and 25 - 75 % of cow manure as a medium mixture. The result showed that the structure of vermicomost is soft and<br />black colors with cation capacity is 17.49 - 21.32 megll00. The mineral content were determined using X-ray Fluorescence Spectrometer (XRF), UV-Vis Spectrophotometer and Kjeldahl, the result showed that the concentrations of N are 0.93 - 0.94 %, CI N 11.26 - 15, K 6.64 - 6.95 %, Ca 12.1 - 17.3 %, P 0.09 - 0.16 %, Mn 0.11 - 0.19 %, Fe 2,01 - 2,69 %, Zn 538 - 779 mgl kg. The earthworm biomass was increased until third<br />weeks of vermicomposting.

To determinine the inhibitory mechanism of antibacterial Maillard reaction products (PRM), heated mixtures containing GL (glukosa-tisin) and TU (molasses-urea) were were studied fcx their effect on uptake oxygen and iron solubility. It was found that the tested PRM had an inhibitory effect on the uptake of oxygen was observed. The PRM also had an effect on the solttbirity of iron in nutrient broth and in phosphate buffer. While the GL mixture<br />reduced the solubility of iron it was increased by the TU mixture.
