Abstract

Di Indonesia, tanah-tanah marginal dengan kandungan pasir tinggi ( tanah vulkan berpasir kasar dan tanah berpasir digumuk-gumuk pantai), merupakan contoh dari banyak tanah bermasalah. Oleh karena itu upaya untuk mengatasi tanah bermasah tersebut perlu dilakukan. Budidaya pertanian pada tanah pasiran akan dijumpai banyak kendala yang berkaitan dengan sifat fisik, kimia dan hidrologi tanah serta iklim yang kurang kondusif bagi pertumbuhan tanaman, lebih khusus lagi tanah tersebut mempunyai sifat mudah meloloskan air, kandungan bahan organik rendah serta suhu tanah yang tinggi, sehingga kurang sesuai untuk pertumbuhan tanaman. Dengan menambah bahan pengkondisi tanah maka telah dapat merubah sifat fisik dan kimia tanah. Perubahan fisik tanah tersebut mengarah pada berat volume tanah yang meningkat, porositas tanah menurun,permeabilitas tanah menurun dan kadar lengas tanah meningkat. Keberadaan mikroba didalam tanah memegang peranan penting dalam transpormasi yang menyebabkan perubahan dalam sifat fisik dan kimia tanah.

Abstract

Penelitian ini bertujuan mencari alternatif limbah organik sebaga bahan baku pembuatan media tumbuh mikroalga Chlorella sp, dimana bahannya melimpah, mudah diperolehdengan harga lebih kompetitif. Beberapa literatur menyebutkan bahwa rumput laut banyak tersebar di perairan laut Nusantara dan memiliki kandungan nutrien (makro dan mikro) yang tinggi, sehingga limbahnya pun diperkirakan masih mengandung unsureunsur yang dibutuhkan untuk pertumbuhan mikroalga. Hasil analisa nutrien pada limbah padat rumput laut, menunjukan kandungan mikro nutrien yang tinggi, kecuali unsurnitrogen (N) dan posfor (P) yang tersedia relatif rendah, namun masih layak digunakan sebagai media mikroalga. Hasil uji pemanfaatan limbah industri pengolahan limbahrumput laut (LR) dan limbah rumput laut yang sudah diperkaya dengan unsur N (LRP) dibandingkan dengan media F/2 Guillard (FG) menunjukan bahwa limbah rumput laut LRP dapat dimanfaatkan sebagai media kultur mikroalga yang ditunjukan oleh tingkat kepadatan dan laju pertumbuhan mikroalga lebih baik dibandingkan dengan media FG maupun LR (LRP>FG>LR).Dari hasil pembahasan, dapat disimpulkan bahwa media kultur asal limbah proses pengolahan rumput laut LRP membuktikan bahwa limbahorganic dari proses pengolahan rumput laut dapat digunakan sebagai bahan baku pembuatan mediam tumbuh mikroalga, khususnya Chlorella sp.

Abstract

A-14-year (1979-1993) image satellites of Solar Radiation, NOAA and SeaSurface Height Anomaly of TOPEX/POSEIDON and ERS-2 have been used to study a reducing solar radiation received by the Earth (global dimming) and to predict local weather anomaly for the future climate prediction in the Indonesian region. The result shows that a dimming of solar radiation is of 16.6% during 14-year observation. It is higher than the mean increasing of global dimming of 2 - 3% for every decade. This explicitly indicates that the air pollution in the form of aerosols from industrial sectors has large contributions to this this dimming process. At the other side, there is a trend of dominant warm water in the southern Jawa-Bali that affect on the increasing of rainfall intensity in the Indonesian region. We predict that flood and a longer dark during the day time, and more variative local weather change will be more frequently happen in the Indonesian region in the futu

Abstract

ABSTRACTLandfills contain materials that can be recovered to be recycled or used as an energy source. The purpose of this study is to conduct waste characterization that has long been buried in landfill which includes analysis of composition, proximate analysis, and ultimate analysis. Then the waste is analyzed for its use as recycled material and energy sources. The study was conducted at the Sukawinatan landfill (Palembang) and the Bantargebang landfill (Bekasi). Sampling was carried out on garbage that had been buried in landfills by digging at depths of up to 5 m using an excavator. Furthermore, the samples are dried in the sun, sifted with rotary screen, and sorted manually. Some samples were taken by quartering to be analyzed in the laboratory. The results of the research and analysis showed that (i) landfill waste was dominated by compost material (31-47%) and plastic combustible material (32-43%) and nonplastic combustible material (32-43%); (ii) shaped material such as compost has the potential as a substitute for landfill cover and as soil conditioner; (iii) potentially recycled materials such as plastic waste need intensive sorting and cleaning; (iv) landfills excavated waste can be potentially used as an energy source or refuse-derifed fuels (RDF) with a heating value between 7.31-15.61 MJ / kg; (v) landfills excavated waste has the potential to be used as fuel for incinerators; (vi) utilization of landfill waste for the cement industry still faces several obstacles such as high chlorine content and water content.Keywords: landfill, waste characterization, composition, proximate, ultimate ABSTRAKTPA mengandung material yang dapat diambil untuk didaur ulang atau dimanfaatkan sebagai sumber energi.

Abstract

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

Abstract

Urban green space plays several roles in balancing the urban ecosystem and maintaining the environment sustainability. Firstly, the urban green space plays a valuable role in prevention of flooding. Trees restrain the movement of sediment and run off. Secondly, the urban green space plays an important role in water conservation, since the tree’s roots absorb some excess water from the soil, making the soil drier, and are able to store morerainwaters. Therefore, the analysis of natural capability of a region in water conservation and flood prevention should become the basis to produce sustainable spatial planning. A study of the importance of green space in maintaining environmental balance in Batam, Malang and Muaro Jambi were conducted by P4W-IPB and P3TL-BPPT by applying the Kato model withsome slightly modifications, to map and evaluate the natural capability of those areas on water conservation and flood prevention. The model is based on validated land evaluation models and ecological value, and mapping the differences between the land covered by green space and that by abandoned areas. Evaluation of the ecological functions of urbangreen space, in combination with other parameters, has been done under GIS and Remote Sensing. The spatial analysis of the ecological function within three areas showed different figures, in which the that 38.12 % of Muaro Jambi, 35.22 % of Malang and 13.36 % of Batam, were functioning properly for water conservation, while 57.71 % of Muaro Jambi, 37.01 % of Malang and 23.75 % of Batam were functioning properly for flooding prevention.

Abstract

High amounts of black liquor wastewater are generated from bioethanol production by using oil palm empty fruit bunches. It contains an alkaline solution (NaOH), so it is quite toxic for aquatic ecosystems if discharged directly into waters. Black liquor has been treated by coagulation method, and it still needs additional treatment. This study aimed to determine degradation of black liquor wastewater by selected white-rot fungi (WRF). Five different strains of WRF have been tested for their ability to decolorize black liquor on agar and liquid media. Out of five fungi studied, two fungi, Ceriporiopsis sp. and Phanerochaete chrysosporium, showed the capacity to grow more than 50% on agar medium. In liquid medium, the percentage of decolorization of 15,000 ppm coagulated and diluted black liquor ranged from 70 to 89% at 30 days depending on the fungal strain. Ceriporiopsis sp. showed the better ability to decolorize black liquor than P. chrysosporium. The performance of Ceriporiopsis sp was evaluated regarding decolorization of black liquor, chemical oxygen demand (COD), and mycelial dry weight both in coagulated black liquor and original black liquor. The color of original and coagulated black liquor can be decolorized up to 90.13 and 86.85%, respectively. COD in original and coagulated black liquor was reduced up to 70.17 and 40.09%, respectively. The presence of coagulant Poly Aluminum Chloride (PAC) inhibited degradation of black liquor by fungus. The result demonstrated that Ceriporiopsis sp has a potential alternative to treat black liquor wastewater.
