Opis:: It was attempted in the paper to describe the growth of oriental goat’s rue (Galega orientalis Lam.) growth by means of a logistic function. The studies demonstrated that the function describes empirical data well as the coefficients of determination obtained ranged between 97 to 98%, depending on the growing season. The estimated function parameters indicate that both the plant height and growth rate were conditioned by thermal conditions and moisture during the growing season. Plants had the longest stems in the year 2010 (127.9 cm), and the shortest in 2008 (105.9 cm). The maximum growth rate ranged from 2.12 to 3.97 cm per day in, respectively, 2009 and 2008. Also the inflection point, the point at which plants grew the fastest, depended on the conditions of the growing season.

Opis:: The capacity of five white rot fungi species to degrade linuron, metribuzin and chlorpyrifos when applied both as single pesticides and mixed together in different concentrations on nutritionally poor media was investigated. Our results suggested that Pleurotus ostreatus, Pycnoporus coccineus, Phlebiopsis gigatea and Τrametes versicolor showed a remarkable tolerance to the pesticides, in all media tested. The EC₅₀ values presented a noticeable difference in the mixtures as compared with the individual ones. The minimum growth rate in the mixture was obtained by P. ostreatus whereas P. coccineus appeared to be more efficient than the rest fungal isolates, when cultivated in the soil extract medium. P. coccineus, P. gigantea and T. versicolor produce high levels of polyphenol oxidase, but only T. versicolor was capable of decomposing linuron when combined with metribuzin and chlorpyrifos.

Tytuł:: The Growth Rate of Water Hyacinth (Eichhornia crassipes (Mart.) Solms) in Rawapening Lake, Central Java

Opis:: Rawapening Lake is one of Indonesia’s national priority lakes that is experiencing environmental problems which are urgently required to be solved due to its functions. The decline in the environmental quality of Rawapening Lake includes sedimentation, water pollution and excess of nutrients, especially Phosphorus (P) and Nitrogen (N) into the lake that induced uncontrolled growth of aquatic plants, one of which is water hyacinth (Eichhornia crassipes (Mart.) Solms). Many activities had been done to reduce the covering of water hyacinth in Rawapening Lake that tends to increase by the time, but no significant result has been achieved. Therefore, this research was conducted in order to study the growth rate of water hyacinth with mesocosm in Rawapening Lake as a baseline to develop suitable management. There were three different sites, namely: Site I in the floating net cage area (FNCA), Rowoboni Village, Site II in the natural area of Bejalen Village which is far from the aquaculture sites, and Site III in the upper reaches of the Tuntang river, Asinan Village. The research was performed in November-December 2019 with the measurements of growth rate, addition number clump and water hyacinth covering every week. The experiment was conducted in the 1 x 1 meter mesocosm, with three replication in every site. In every mesocosm water hyacinth with similar initial weight of 160 grams and number of leaves 6-7 strands were grown in the mesocosm. On day 7 (H7) the average wet weight of water hyacinth increased by 201%. In the fourth week (H28) the average wet weight of water hyacinth increased by 788% compared to the initial weight when planted. The highest relative growth rate (RGR) value of water hyacinth was at site III (7.26%/ day), followed by Site I (7.03%/day), and Site II (6.40%/day), respectively. The doubling time (DT) value of water hyacinth at the site I was 9.9 day, site II – 10.8 day, and site III – 9.6 day. One clump of water hyacinth weighing 160 grams was able to cover 1 m2 of mesocosm within 21 days. On the basis of these results, to manage water hyacinth blooms one has to consider its growth rate.

Opis:: Palm oil clinker media (POCM), which is a by-product of incineration process from palm oil industry, creates environmental sustainability issues. This is due to the method of handling solid waste material of industry by simply dumping it on an open land area. The previous study of POCM including physical and mechanical properties of solid present showed promising results of utilizing POCM as a packing media for treatment of domestic wastewater industry. The packing media can be used in the process of biological wastewater treatment system in Sequencing Batch Reactor (SBR) mode. By adopting POCM as an attached growth media, this research paper focuses on the performance of POCM in SBR mode in the context of organic and nutrient removal rate. The performance pertaining to the removal of organics and nutrient was measured using USEPA Standard Method for Chemical Oxygen Demand (COD) and Ammonia. The average rate of removal for COD and Ammonia per biomass adopting POCM in sequencing batch reactor mode is 0.0069 mg COD/mg MLVSS and 0.001 mg Ammonia/mg MLVSS.
