Abstract

Bioremediation of petroleum sludge was conducted by using land-farming method in micro scale and by applying an indigenous bacteria Bacillus megaterium. The samples were from PT. Pertamina Musi Banyuasin district of South Sumatra. The research aim was to evaluate the performance of the bacteria in degrading petroleum sludge. The rate of the biodegradation process was determined by using differential method and the data analyses show that the reaction order is 0.74. Then, the rate of biodegradation constant was determined by using an integral method assuming that the biodegradation process was a first reaction order. From the calculation, it was revealed that the biodegradation reaction constant was 0.0204/day. The bioremediation-kinetics model is y = -0.0204X + 2.0365, and by using this model the bioremediation process could be ended after 99.83 days. The qualitative analysis was carried out by using GC-MS to investigate the components of compounds changed during the bioremediation process. The results show that the B. megaterium could degrade 99.32% of alkane compounds.

Abstract

This research titled “Change Some Properties of Chemical and Biological Ultisol and Nutrient Uptake of N P K Plant and Production of Fresh Fruit Bunches Marked Palm Oil Mill Effluent”. This research held from April till December 2014. The results showed that the application LCPKS can improve nutrient P , but has not been a significant influence on the chemical properties of the other on the ground in oil palm plantations. Liquid Waste Award mills are capable of increasing the population of micro- organisms in the soil first and third day of observation.  Results of weighing directly on the ground show that the weight of fresh fruit bunches (TBS) reached an average of 30.45 kg per bunch in the treatment on non LCPKS and weighs TBS averaged 21.48 kg per bunch . This shows that LCPKS can increase the weight of TBS as well as production

Abstract

The purpose of this research was to obtain the effectiveness level of bioremediation process of oil residue on SBE waste by using the isolates of lipolytic fungus Aspergilus fumigatus, Cylindrocladium sp and Fumago sp. This research was conducted by using completely randomized factorial design with 3 factors of treatment which consist of nutrient ratio (N:P:K) that were divided into three levels, namely n1=A(7:1.5:0.5), n2=B(14:3:1), n3=C(21:6:1.5). The humidity were divided into 3 levels treatment i.e. k1 (90%), k2 (80%), k3 (70%) and time that were divided into four levels, namely w1 (week 1), w2 (week 2), w3 (week 3), and w4 (week 4) with fixed pH i.e. pH 6, so that were obtained 36 combination of treatment and for each treatment combination repeated 3 times. Sampling of SBE waste was conducted in one cooking oil factory in South Sumatera using randomized sampling method as much as 24.000 g. The results showed that 80% humidity and nutrient A as the best treatment for lipolytic fungus consortium performance to degrade the SBE waste with the average percentage of oil degradation as much as 74.83%. 80% humidity and nutrient A was an effective interaction in affecting the percentage of oil degradation.

Abstract

Abstrak. Penelitian ini bertujuan untuk menganalisis stabilitas agregat tanah dengan perlakuan berbagai isolat bakteri pemantap agregat (BPA) dan bahan organik berupa kompos yang terbuat dari campuran 90% rumput Cyperus pilosus Vahl dan 10% kotoran sapi, dengan masa inkubasi yang berbeda. Taraf perlakuan terdiri dari kontrol, kombinasi isolat I, II, dan III masing – masing dikombinasikan dengan komposisi bahan organik 0%, 0.5%, dan 1%. Hasil penelitian ini menunjukkan aplikasi isolat BPA pada tanah pasir berlempung disertai pemberian bahan organik menyebabkan populasi yang lebih tinggi dibandingkan tanpa aplikasi keduanya. Klebsiella sp. LW-13 yang dikombinasi dengan 1% bahan organik dan Bukholderia anthina MYSP113 yang dikombinasi dengan berbagai taraf bahan organik (0 hingga 1%) menyebabkan agregat menjadi sangat mantap sekali pada pengamatan 60 hari setelah aplikasi. Eksopolisakarida yang dihasilkan bakteri akan mengikat partikel tanah dan membentuk agregasi. Penggunaan bakteri Bukholderia anthina MYSP113 dinilai lebih efisien dalam pemanfaatannya untuk memantapkan agregat tanah karena memiliki kemampuan terbaik untuk memantapkan agregat tanah hingga sangat mantap sekali dengan atau tanpa penambahan bahan organik pada periode 60 hari pengamatan.Abstract. This study aimed to analyze the aggregate stability of soil with sdifferent treatments of aggregate-stabilizing bacteria and organic matter (compost made of mixture of 90% Cyperus pilosus Vahl grass biomass and 10% cattle manure) at different incubation period. Treatments consisted of control, combination of three different isolate with three different composition of organic matter (0%, 0.5%, and 1%). The results showed that the application of aggregate-stabilyzing bacteria to loamy sand soil and organic matter causes a higher bacteria population than without both applications. Klebsiella sp. LW-13 combined with 1% organic matter and Bukholderia anthina MYSP113 which was combined with various levels of organic matter (0 to 1%) showed high aggregation at observation of 60 days after application. The exopolysaccharide produced by bacteria binds soil particles and forms soil aggregation. The use of Bukholderia anthina MYSP113 bacteria is considered to be efficient in its utilization to stabilize soil aggregates because it has the best ability to stabilize soil aggregates to be highly stable with or without the addition of organic matter in the 60-day observation period.

Abstract

Coal fly ash and Azolla biomass are potential materials to be used as raw materials for the manufacture of briquette fertilizers. In this study, the coal fly ash, azolla and urea in various compositions were mixtured to make briquette fertilizers. The study was conducted to evaluate the physical properties of briquette fertilizers, i.e bulk density, compressive strength, porosity, and water holding capacity on various compositions of fly ash-azolla and urea. The research was arranged in a Completely Randomized Design with three replicates. The formulation of briquette fertilizers as treatments was made with the compossition (w/w, dry-weight basis) of (fly ash : azolla) + urea as follows: (40:60)90+10; (40:60)80+20; (40:60)70+30; (50:50)90+10; (50:50)80+20; (50:50)70+30; (60:40)90+10; (60:40)80+20 and (60:40)70+30. The results showed that the variation in composition of coal fly ash-azolla and urea significantly affected the compressive strength, bulk density, water holding capacity and porosity of briquette fertilizers produced. The increase in the proportion of fly ash or the decrease of azolla biomass proportion tends to increase compressive strength and bulk density, and tends to decrease the water holding capacity and porosity of briquette fertilizers produced.

Abstract

Paripurna et al, 2017. Response of Lime Application to Some Soil Chemical Properties of Tidal Swamp Land. JLSO 6(1):59-70.Tidal swamp land of Banyu Urip Village Banyuasin District South Sumatera Province has a pH 4.5, 4.96 cmolkg-1 Al-exch, >20% Al saturation, low Ca and Mg availableity and contain Pyrite. This study analyzed response of lime application to some soil chemical properties of tidal swamp land. Lime used was dolomite. The research was conducted on April 2017.Lime dosages consisted of 0.00 ton ha-1, 0.81 ton ha-1, 1.63 ton ha-1, 2.45 ton   ha-1, 3.26 ton ha-1 and 4.07 ton ha-1 respectively mixed to 10 kg soil and placed to polybags than incubated for 7 days.Variables measured were soil pH, K-exch, Ca-exch, Mg-exch, Al-exch, CEC, H-exch and Al saturation. The results showed that lime with 3.26 ton ha-1 dosage gived best results by increased Mg-exch up to 0.85 cmolkg-1 and   decreased H-exch down to 1.14 cmolkg-1, while lime with 4.07 ton ha-1 dosage gived best results by increased soil pH up to 4.95, K-exch 0.64 Cmolkg-1, Ca-exch 2.18 cmolkg-1, and CEC 15.23 cmolkg-1, also decreased Al-exch down to 1.96 cmolkg-1 and Al saturation down to 12.87%. Lime as an ameliorant to acidic soil is effective to increase soil nutrients, decrease soil acidity, Al-exch and Al saturation that influenced by fertilization.
