Abstract

Water quality index (IKA) is one tool to quickly predict the environmental quality status of an ecosystem or region to obtaining an alternative of the future management. Toanalyze the status of these indices utilize only data of environmental parameters that have been established as a key parameter determining the IKA. From the analysis of the mining area of PT KPC IKA with key parameters TDS, DO, COD, nitrogen (N) and phosphorus. (P) derived from the water quality of agricultural ecosystems, industry / mines and residential showed an index value of less well with thecategory (54.6163) on the interval 40 ≤ IKA <60. The low index value is proportional to the low value of ecosystem quality index industry / mining IKA (I) with a value of 45.82with categories of less well on the interval 40 ≤ IKA <60. Consider, that the index value of ecosystem quality residential IKA (H) and agricultural ecosystem quality index IKA (P) with good and excellent categories, then the ecosystem of industry / mining is the focus that needs to be considered for improved management efforts.

Abstract

Fourteen compounds were isolated from acetone extracts of three species of seaweeds (Eucheuma serra, a red seaweed, Halimeda opuntia, a green seaweed, and Hydroclathrus clathratus, a brown seaweed) using bioautographic TLC methods and identified using GC-MS. From Eucheuma serra were isolated 8 compounds (3 fatty acids, 3 steroids, and 2 aldehyds). Only two compounds of fatty acid camefrom Halimeda opuntia, whereas Hydroclathrus clathratus produced 6 compounds (4 fatty acids, one compound each of steroid and ether). All isolated single compoundswere tested for their antibacterial activities by the agar diffusion method against the Gram-positive bacteria Staphylococcus aureus, Bacillus subtilis and Streptococcusfaecalis, and the Gram-negative bacteria Echerichia coli, Pseudomonas aeruginosa and Salmonella typhimurium. All 14 compounds showed activity against Gram-positivebacteria, especially Bacillus subtilis, and only 2 compounds showed activity against Gram-negative bacteria Escherichia coli. Nine compounds showed activity against Staphylococcus aureus, and 4 compounds showed activity against Streptococcusfaecalis. All compounds were not active against Pseudomonas aeruginosa andSalmonella typhimurium bacteria. This study indicated that there is indeed a diversityboth in kinds and in molecular structures of the antibacterial substances.

Abstract

Organic fertilizer is a fertilizer that is expected to improve the physical, chemical, and biological properties of the agricultural land resources, which is undergoing fertilityand productivity degradation. Compost is one of the organic fertilizers produced from the biological decomposition process by a consortium of microorganisms, includingfunctional microorganisms. To make it easier for farmers and efficiency in the use of organic fertilizer, organic fertilizer will be further processed into granular form and is called Granules Organic Fertilizer (POG). In the manufacturing process, namely at the time of drying using a rotary dryer, was suspected of using high temperatures to kill microbes (including functional microbial) that naturally exist in the organic compost fertilizer (POK), which is the raw material for POG. To increase the presence of functional microbial populations, the POG which has produced before, then added with bio fertilizer that is rich in microbial functional. This research was conducted to determine and evaluate the total microbial population and functional microbial in pure POK, compared with the total microbial population and functional microbial in the POG are enriched with bio-fertilizer. The results showed: There is an indication to the higher number of total microbial population in the POK, who showed by total fungi population, compared with the POG. The number of functional microbial population, as shown by bacterial phosphate solvent and non-symbiotic bacteria that are fastening N in POK, very high and already meets the criteria to be called as a biological fertilizer. The amount is not significantly different compared to the POG that is already enriched with bio fertilizer that is rich in microbial functional. There is an indication of the influence of high heating using a rotary dryer, in the POG manufacturing process against the decreasing of the amount of microbialpopulation that are resulting in the POG, including functional microbial

Abstract

A study to improve the raw water quality at Taman Kota Drinking Water Company was conducted by using pilot plant of biofiltration system. The pilot plant was run by pumpingthe raw water from river to the reactor continuously with various Hydraulic Retention Time. Samples of raw water and treated water were taken daily and analyzed for pH,Total Suspended Solid (TSS), Organic matter, Ammonia nitrogen and Detergent (MBAS). The results showed that performance of biofiltration system decreaed due to shortening Hydraulic Retention Times (HRT). The longer HRT caused bigger volume of biofiltration tank. Therefore, this study suggests that the optimum Hydraulics retention time is 1 hr. In this HRT, the treated water quality were 7.2 for pH, 40 mg/l for TSS, 10,7 mg/l for organic matter, 0.35 mg/l for ammonia nitrogen and 0.1 mg/l for MBAS. These resultscomply with the Regulation No. 582 year 1995 for raw drinking water quality (class B).

Abstract

Aloe vera (L.) Burm.f. of the Asphodelaceae, which probably originated in North Africa is a very short-stemmed succulent, perennial plant of 80-100 cm in height. Today, it is widely grown in the tropics worldwide. It has long been used as a traditional herbal medicine and as cosmetic materials since thousand of years BC in Egypt, China, Greece, etc. It can be used externally to treat various skin conditions and It was useful for curing diabetics, cancer, HIV, even for stress and drug addicts The biologically active components found in the juice of aloe leaves are anthraquinones, acemannan, andprostaglandins. Chunks of aloe pulp are popular as beverages in Asia. Aloe has long been propagated by splitting its off-shoots, and this may account for its narrow genetic variations. In this research, genetic variations of A. vera and A. vera var. Chinensis, were induced by gamma irradiation. In vitro shoots of Aloe were irradiated with gamma ray at the dosage of 10-60 gy, then propagated on Murashige and Skoog (MS) solid medium containing 1 mg/l BAP. The results showed that shootlets of A. vera var. Chinensis were still alive up to 40 gy but the leaves became stiffer, while A. vera only tolerated irradiation up to 20gy. At 50-60 gy, all cultures died after 2 months. Visual observation on irradiated in vitro shoots showed that new variants appeared at the dosage of 20 gy, although in very low frequencies. Leaves became half green and half white in A. vera and white-green-white in A. vera var. Chinensis. Confirmation whether those variants were of genetic or morphological origin needs to be further investigated.
