Kanigoro at Ngablak Sub-District in Magelang is one of the Villages which is topographically lower than the adjacent village in the same sub-district. The main activity of village inhabitant is farmer in intensive agriculture that is indicated by a lot of fertilizer and pesticide utilization. Therefore, the exceeding dosage of fertilizer and pesticide in plant cultivation could become an anxious environmental problem due to the high concentration of them in springs water that they called as Tuk and river water more than the quality standard of National regulation. Based on Data analysis, it can be concluded that laboratory analysis result of water quality in the village Kanigoro, generally still meet the quality standard. This is showed by the concentration of heavy metals (As, Cu, Cd, Hg, Zn and Fe) and pesticides (Aldrin, BHC, Chlordane, DDT, Dieldrin, Endrin, Heptachlor,Heptachlo epoxide, Lindane, Methoxychlor and Toxaphene), except for some points sampling contain heavy metals plumbum (Pb) exceeded water quality standard of the Minister of Health (Depkes) and Government Regulation Class I (raw water) of PP 82/2001. While the density of microbial total coliform and E. coli detected abundant compare to the water quality standard of the Minister of Health, particularly for the use of water as raw water or clean water. However, it is possible to utilize water directly for agriculture and fish farming activities and the use for drinking water after cooked first

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.

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

Solid waste management is a system involving all subsystems of management such as institutional, law, financing, operational, and community participation. Waste law which shelters the solid waste management is the umbrella of all local regulation (Perda). But in fact, its implementation and aplication have not run well as expected. Using a simple analisys method from personal experience as an Adipura award appraiser, thewriter tried to reveal the strengths and weaknesses in waste management all this time. The result shows that local governments, in general, haven’t considered the wastemanagement subsystems integratedly in handling the municipal garbage. They usually see the problem partially, not as an integrated system which includes all the subsystems. Municipal waste management should not become a proses which is independent fromthe other subsystems. It is recommended that the head of regional government see the waste management.

Pada umumnya peneliti menentukan status kualitas perairan menggunakan data yang diperoleh dengan plankton-net. Data tersebut tidak menceminkan kepadatan dan struktur komunitas fitoplankton yang sebenarnya. Oleh karena itu data tersebut kurang layak untuk menganalisis status kualitas perairan. Artikel ini menyampaikan hasil kajian kelimpahan fitoplankton di perairan tawar dan laut, yang diperoleh dengan dan tanpa menggunakan plankton-net. Kepadatan yang diperoleh dengan planktonnet menghasilkan nilai yang jauh lebih kecil dari kepadatan yang diperoleh tanpa menggunakan plankton-net. Ini mengisyaratkan bahwa untuk menganalisis status kualitas air, lebih layak menggunakan data yang diperoleh dengan tanpa plankton-net kata kunci: fitoplankton, plankton-net, nutrien, eutrofikasi, struktur komunitas.AbstractIn general, researchers determine the status of water quality using data obtained with a plankton-net. The data do not reflect the density and the actual structure of phytoplankton communities. Therefore, the data is not feasible to analyze the water quality status. This article present the results of the study the abundance of phytoplankton in freshwater and marine, which obtained with and without using a plankton-net. Density obtained with a plankton-net produce values that are much smaller than the density obtained without using a plankton-net. This implies that in order to analyze the status of water quality, is more feasible to use data obtained with the no-net plankton key words: phytoplankton, plankton-net, nutrients, eutrophication, the community structure.
