Abstract

Uji degradasi minyak dari enam isolat bakteri (P1, P2, P3, P4, P5 dan P6) dan konsorsiumnya (K1, K2 dan K3) telah dilakukan dalam skala laboratorium. Isolat-isolat bakteri tersebut berasal dari tanah tercemar minyak di sumur pertambangan minyak di Siak, Riau. Konsentrasi awal minyak yang digunakan dalam kultur percobaan adalah 2.4 g/100 ml. Nilai Total Petroleum Hydrocarbon (TPH) diukur pada hari ke-12 percobaan.Dari enam isolat yang dicoba, isolat P2 dan P6 memiliki nilai TPH terendah yaitu masing-masing sebesar 0.44 g (atau terjadi penurunan TPH sebesar 69.9%) dan 0.49 g (65.5% penurunan TPH). Isolat P2 dan P6 ini kemudian dipilih dan dikombinasikan untuk menentukan formulasi isolat terbaik dalam percobaan konsorsium. Kombinasi isolat bakteri yang dicoba dalam percobaan konsorsium adalah K1 (campuran dariisolat P2 dan P6 dengan rasio 1:1), K2 (campuran dari isolat P1, P2, P3, P4, P5 dan P6 dengan rasio 1:1:1:1:1:1) dan K3 (campuran dari isolat P1, P2, P3, P4, P5 dan P6 dengan rasio 1:3:1:1:1:3). Konsentrasi awal minyak yang digunakan dalam percobaan adalah 2.7 g/100 ml. Nilai TPH terendah ditemukan dalam kultur K1 yaitu sebesar 0.43 g, atau terjadi penurunan nilai TPH sebesar 84.2%. Nilai TPH pada kultur K3 adalah 0.68 g atau terjadi penurunan sebesar 78%. Nilai TPH ini lebih tinggi dari K1, namunlebih rendah dari K2 ataupun kultur tunggal P6. Hasil dari percobaan ini menunjukkan bahwa tingkat degradasi minyak dapat ditingkatkan dengan menggunakan campuran dari isolate-isolat tertentu. Kata kunci: bioremediasi minyak, biodegradasi, konsorsium mikroba AbstractLaboratory experiments have been conducted to test the effectiveness of six bacterial isolates (P1, P2, P3, P4, P5 and P6) and their consortia (K1, K2 and K3) to degrade crude oil. The bacteria were obtained from the oil-contaminated soil around well sites in Siak, Riau. The initial amount of crude oil added into the culture media was 2.4g/100ml. Total petroleum hydrocarbon (TPH) was determined after 12 days of culture. Of six isolates, isolate P2 and P6 had the lowest TPH value after 12 days of culture, i.e. 0.44 g (69.9% oil reduction) and 0.49 g (65.5% oil reduction), respectively. Therefore, isolate P2 and P6 were selected and mix to determine the best combination of bacterial strains in a consortium. The combinations of bacterial isolates representing three mix  cultures were K1 (mix culture of isolate P2 and P6 with 1:1 ratio), K2 (mix culture of isolate P1, P2, P3, P4, P5 and P6 with 1:1:1:1:1:1 ratio), and K3 (mix culture of isolate P1, P2, P3, P4, P5 and P6 with 1:3:1:1:1:3 ratio). The initial amount of crude oil addedinto the cultures was 2.7 g. The lowest TPH value among the three mix cultures was found in K1 i.e. 0.43 g, or there was a 84.2% oil reduction. K3 had a higher TPH value than K1 (0.60 g or 78% reduction), but had a lower value than K2 or the single culture P6. Results from this study showed that oil degradation rate can be increased using mix culture of selected strains. Key words: oil bioremediation, biodegradation, microbe consortium

Abstract

The gases produced from Sanitary Landfill are to be monitored and collected so as not to cause environmental pollution. TPA Bangklet in Bangli District, Bali Province iscurrently being reviewed and further developed to be pilot Sanitary Landfill in Indonesia. A system of monitoring and capturing or collecting LFG (Landfill Gas) has been done toBangklet’s Sanitary Landfill of the dry Cell Pilot Plant, especially for the second layer. LFG measurement results show the average value of 32.99% for CH4, 31.87% for CO2, 5.4% for O2 and up to 29.68% for other gases. But the arrests and the collection of LFG system still needs improvement, because there are some leaks that led to the entry of oxygen into the system and vice versa the LFG is released into the atmosphere. It is suggested that the pattern of capture, and utilization of LFG monitoring system have to be applied to all Sanitary Landfills located in Indonesia.

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.

Abstract

Indonesia has one of the largest Coal Bed Methane (CBM) reserves in the world with a potential 453 trillion cubic feet (“Tcf”), more than double the country’s natural gasreserves. The government, therefore, is planning to exploite its huge potential reserves and targetting to produce 1 billion standard cubic fee per day, or about 0.18 million barrelof oil equivalent, by 2025. Several new regulations have been passed, but non is related to protection to the environment as an impact of the development of CBM. If it is not well regulated and managed properly, the environmental impact will be enormous. This paper presents assessment results on the environmental and social impacts which likelywill be faced by Indonesia from improper development of CBM in Indonesia. Certainly, there will be very serious and unaviodable negative impacts to the environment withoutcareful plan and proper environmental regulation put in place prior to the development of CBM. The government will have to develop a specific regulation regarding CBMdevelopment in the near future before everything is too late.

Abstract

he natural resources utilization for economic development has become the driver of land cover and environmental change. Logging and coal production have created dryland. The policy of natural resources utilization for development in Kutai Timur Regency has changed the net value of its natural resource capital. For Kutai Timur Regency it is recorded that between the year of 2004 - 2006, the income of its natural resources was as much as Rp. 13,39 Trillion. The total change of the economic value of its resource has also created the need for the environmental cost of Rp. 191 Billion annually since around 95,742 ha has changed into dry land. However comparing to the need of annual budget to treat the critical land, the net value of its natural resources capital is relatively high.

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

Isolation of endophytic fungi was done to find alternative microorganisms as biocontrol agents against Rhizoctonia solani Kuhn, a soil borne pathogen on many agriculturalcrops. The research objectives were 1) to isolate and identify endophytic fungi colonize plants growing on agricultural and Mount Salak supporting forest lands in the Villages of Parakan Salak and Cimalati, Sukabumi; and 2) to screen for their biocontrol agent activity againt R. solani. Diameter of R. solani was measured on day 2 after inoculation, and its percent inhibition of growth by endophytic fungi is calculated using the formula Skidmore & Dickinson (1976). The results indicated that 214 isolates of endophytic fungi were isolated from 96 plant species that growing in both places. Endophytic fungi isolated including in the group of Aspergillus, Cladosporium, Colletotrichum, Curvularia, Drechslera, Fusarium, Guignardia, Mucor, Nigrospora, Paecilomyces, Penicillium, Pestalotiopsis, Phoma, Phomopsis, Rhizoctonia, and endophytic fungi that have not been identified. Of the 214 fungal isolates tested, 39 isolates (18.22 %) could inhibit the growth of R. solani from 10.18 % to 58.99 % with a percent inhibition. The highest growth inhibition of R. solani were shown respectively by an unidentified fungus isolatedfrom Hyptis capitata Jack (58.99%), Cladosporium sp. isolated from jeruk bali (Citrus grandis (L.) Osbeck) (55.42%), Pestalotiopsis sp. isolated from pine apple (Ananas comosus (L.) Merr.) (53.85 %), and Paecilomyces lilacinus (Thom) Samson isolated from banyan (Ficus benyamina L.) (51.81%)
