The experiment was carried out to evaluate the water and soil quality of pond, which were subjected to drying and aeration after inundation. The objective of the experiment was to find out which soil drying and water aeration treatments were the best for shrimp culture.The soil used was obtained from an intensive shrimp pond and sea water was collected  from pond area in jepara coast. The soil drying treatments consisted of drying the wet soil under the sun to air dry condition, field capacity condition and water saturated condition. The soil drying treatments were carried out for 64 days. The aeration treatments after inundation consisted of with aeration and without aeration. Soil less sea water also was prepared as control. The aeration treatments were carried out for 64 days. The soil and water quality were  observed during soil drying and water aeration treatments.Result of this experiment indicated that drying the pond bottom soil until field capacity condition gave the highest rate of organic matter decompotition followed by air dried soil, then water saturated oil. The decompotition of soil organic matter in the field capacity condition reached optimum on day 8 to 16. The pond bottom soil in water saturated condition contained lower NH3, NO2- and H2S than ind dried soil. Aeration gave better condition than the non aeration one. It seemed the best water quality condition for shrimp fry stocking occurred 4-8 days after inundation combined with aeration.

Changes of microbial indices of water quality in the Vistula and Brda rivers as a result of sewage treatment plant operationThis paper reports the results of studies of microbiological changes in the water quality of the Vistula and Brda rivers after the opening of sewage treatment plants in Bydgoszcz. The study involved determining the microbiological parameters of water quality. Based on the results obtained, it was found that the quality of the water in both rivers had improved decidedly after the opening of the plants, although an increased number of individual groups of microorganisms was found at the treated sewage outlet from one of the plants.

Environment Degradation

Environment degradation in Rawa Pening’s lake is caused of descend lake’s functions for some potentions and activities around the lake. Some problems in the Rawa Pening’s lake has emerged i.e : decrease water quality of lake, abundance of water hyacinth growth and increase sediment in the bottom lake. A research about infl uences of land ecosystem on Panjang and Galeh river corridors for Rawa Pening’s lake has been done. Two rivers named Galeh and Panjang are the largest water contribution in Rawa Pening’s lake. That caused the land characteristic ecosystem of that river corridors gives infl uences in the Rawa Pening’s lake.Key words: land ecosystem, river corridor, water contribution, Rawa Pening Lake.

The study aims to determine the quality of clean water in the villages of Wainitu, Batumerah, Amahusu and Halong by comparing the result of water quality analysis with water quality standard. Water quality analysis includes Physiscal, Chemical, and Microbiological parameters. This research uses descriptive method, this method describes systematics, accurate about facts and characteristic of the quality of clean water of each research location. The results showed that the source of clean water in the village of Batumerah did not meet the standard of clean water quality standards indicated by the number of E. coli and the high total coliform.  Keywords: standard quality of clean water, water quality, Wainitu, Batumerah, Amahusu and Halong villages   ABSTRAK Penelitian yang bertujuan untuk menetapkan kualitas air bersih di Desa Wainitu, Batumerah, Amahusu dan Halong, dengan membandingkan hasil analisis kualitas air dengan standar baku mutu air bersih. Analisis kualitas air meliputi parameter fisika, kimia dan mikrobiologi. Penelitian ini menggunakan metode deskriptif; metode ini menggambarkan sicara sistematis, akurat, fakta dan karakteristik mengenai kualitas air bersih di masing-masing lokasi penelitian. Hasil penelitian menunjukkan bahwa sumber air bersih di Desa Batumerah tidak memenuhi standar baku mutu air bersih yang ditunjukkan oleh jumlah E. coli dan total Koliform yang tinggi. Kata Kunci: baku mutu air bersih, Desa Wainitu, Batumerah, Amahusu dan Halong, kualitas air
