Abstract

Bioremediasi tanah tercemar minyak bumi telah diatur dalam Keputusan Menteri Negara Lingkungan Hidup nomor 128 Tahun 2003. Salah satu faktor yang menentukankeberhasilan penerapan bioremediasi adalah ketersediaan mikroorganisme yang mampu mendegradasi cemaran minyak bumi. Tujuan dari penelitian ini adalah mengisolasi dan mengidentifikasi konsorsium bakteri hidrokarbonklastik dari sampel tanah tercemar minyak bumi yang diperoleh dari Riau dan Bojonegoro. Dari hasil seleksi dan optimasibakteri pada berbagai sampel tanah diperoleh empat isolate/konsorsium bakteri yang mampu mendegradasi minyak bumi, dengan kode konsorsium Ristek122-2.3;Ristek122-5; Ristek122-BN5; 122-Mix. Berdasarkan identifikasi dan uji biokimia, konsorsium bakteri terdiri dari bakteri hidrokarbonoklastik yang mampu menghasilkanbiosurfaktan. Produksi biosurfaktan mampu menurunkan tegangan permukaan sehingga bakteri hidrokarbonoklastik mampu bekerja secara optimal.

Abstract

Evaluasi karakter lahan dan pewilayahan komoditas perkebunan berdasarkan kesesuaian lahan telah dilakukan di Pulau Buru, dimana wilayah ini merupakan salahsatu pulau utama di Provinsi Maluku yang mempunyai potensi sumberdaya lahan yang tinggi. Namun demikian karakter lahan sangat bervariasi dari satu tempat ketempat lainnya karena adanya factor-faktor pembatas di dalamnya. Dalam metodologi dijelaskan secara singkat tentang evaluasi lahan, kesesuaian lahan dan pewilayahankomoditas perkebunan. Kemudian bahasan hasil studi di Pulau Buru disajikan meliputi penggunaan, karakter, dan kesesuaian lahan, serta pewilayahan komoditas perkebunan. Sebagian besar wilayah studi masih ditutupi oleh hutan, dan hanya sebagian kecil yang dimanfaatkan sebagai lahan garapan. Dareah studi terdapat 5 fisiografi terbagi menjadi 15 unit lahan. Sebagian besar lahan masuk dalam katagori tidak sesuai (N), dan hanya sebagian kecil yang masuk katagori sesuai (S). Secara alami yang menjadi factor pembatas lahan adalah kemiringan curam, ketinggian tempat, kedalaman tanah yang dangkal, dan ketersediaan air. Total luasan lahan yang potensial untuk dikembangkansebagai lahan perkebunan adalah 187.902 hektar, dan sekitar 50 % dari lahan tersebut terletak di hutan yang dapat dikonversi.

Abstract

Penanganan pengaruh bahaya tsunami bagi masyarakat pedesaan pesisir sangat penting, dengan bertujuan untuk mengurangi atau meminimalkan dampak kerugianatau kerusakan yang disebabkan oleh musbah tsunami tersebut. Namun, efek bencana alam tersebut mungkin tidak terlalu sering dianalisis dan dipertimbangkan dalam beberapa proyek perencanaan tata ruang di Indonesia. Hal ini disebabkan oleh kurangnya informasi dan data mengenai lokasi tersebut. Wilayah pesisir perlu dilindungi dari dampak tsunami dengan mempertimbangkan sejumlah besar orang tinggal disana dan kegiatan mereka. Adanya pembangunan dari program hutan mangrove oleh pemerintah yang lokal dan peningkatan perencanaan pesisir spasial akan membantu untuk meminimalkan bahaya seperti di pantai.

Abstract

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.

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

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

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.
