Abstract

The bioremediation of petroleum contaminated soil was investigated using a microscale Landfarming. The Indigenousbacteria, Pseudomonas pseudoalcaligenes, Bacillus megaterium, and Xanthobacter autotrophicus were isolated from the contaminated sites Sungai Lilin Jambi Pertamina Ltd and used further in the bioremediation experiments. The biodegradation rates of petroleum contaminated soil in the presence of the isolated bacteria were studied by using the chemical kinetics approach. The reaction orders were studied by using the differential method and the reaction rate constants were studied by using the integral method. The results showed that the reaction orders were 1.0949, 1.3985, 0.8823, and the reaction rate constants were 0.0189, 0.0204, 0.0324 day-1, respectively. Considering the values of reaction orders and reaction rate constants, the biodegradation rate of contaminated soil by usingeach bacteria had significantly different value; Xanthobacter Autotrophicus bacteria could degrade the petroleumoil sludge fastest than the others.Keywords: Biodegradation, indigenous bacteria, kinetics, petroleum oil

Abstract

Palm Oil Mill Effluent (POME) cannot be directly used as an organic fertilizer source due to its high Biological Oxygen Demand (BOD) thus it is not  environmentally safely. To increase the high quality of organic fertilizer obtained, the liquid wastes are needed to be processed in order to decrease the BOD to degrade both the soluble and suspension materials of organic materials. The altenative process to be conducted to make a better quality of POME is by adding the adsorbent. The aim of the research was to study the effect of zeolite utilization and duration of hydrolysis process in order to increase the nutrients content and to decrease the BOD of POME. The research was conducted at  the PT Sumbertama Nusa Pertiwi Jambi, Indonesia in August 2012 until February 2013. The sample of POME was taken from the inlet of the factory’s  acidulating pool. There were several doses of zeolite  as treatments which were 0, 5, 10, 15% and several durations of hydrolysis process which were 1,2,3 and 4 weeks. Active zeolite was added to POME and then it was fermented with different hydrolysis duration times as mentioned above. The research showed that application of  zeolite  and  duration of hydrolysis process significantly affected the pH, N,  P, K, Al, Fe, BOD of  POME and the adsorption of  N, P, K, Al, Fe by zeolite. It can be concluded that 10% of zeolite incubated  in  two weeks duration of hydrolysis process produced higher nutrient of N, P, K  with BOD, Al, Fe and pH matched  with the waste quality standard. The highest efficiency of  N, P and K adsorbent was show by the 15% of zeolite  which was incubated for two weeks of hydrolysis process.Keyword: Hydrolysis process duration, nutrient content, palm oil mill effluent, zeolite.[How to Cite: Nursanti I, D Budianta, A Napoleon and Y Parto. 2013.Zeolite Utilization as a Catalyst and Nutrient Adsorbent of an Organic Fertilizer Process From Palm Oil Mill Effluent as Raw Material.

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

The impact of agricultural activities such as the application of organic and chemical fertilizers will be causing a Cadmium (Cd) contamination. Information on the presence of Cadmium (Cd) both in the soil and Rice Plants in North Talang Ubi, Talang Ubi District, Penukal Abab Lematang Ilir of South Sumatera, Indonesia is still very limited and difficult to obtain for the issue of heavy metal of cadmium (Cd). This study aims to analyze the cadmium content in paddy fields with two different cultivation systems, namely organic and conventional farming systems. This research was a survey method and soil analysis conducted in two locations which were soil from Rejosari with organic farming system and other coming conventional farming system. The soil sampling was done from March 2023 to June 2023. The results of this study showed that the cadmium content in soil in the two cultivation systems is still below the cadmium quality standard, with the highest soil Cd content found 0.00478 mg/kg in the conventional cultivation system where the threshold limit is 0.5 mg/kg. The cadmium content of rice shoot and roots in the two cultivation systems was also still below the quality standards of cadmium, where the highest Cd content was found around 0.03303 mg/kg in the conventional cultivation system where the threshold limit was 0.1 mg/kg.

Abstract

Post-fire tropical peatlands in Southeast Asia face severe ecological degradation, yet the biological dimension, particularly soil microbial abundance as an indicator of ecosystem health, remains understudied. This study aimed to quantify culturable bacterial and fungal populations across different peat layers in a fire-affected peatland in Perigi Village, South Sumatra, Indonesia. Soil samples were collected from two depths  (0-30 cm and 30-60 cm) using a stratified random sampling approach and analyzed with the Total Plate Count (TPC) method on nutrient agar and potato dextrose agar media. Results showed a clear vertical stratification, with microbial populations significantly higher in the surface layer (0-30 cm) than in the subsurface layer (30-60 cm), reaching maximum counts of 2.6×10? CFU g?¹ for bacteria and 8.8×10³ CFU g?¹ for fungi. Sapric peat consistently supported greater microbial abundance than hemic peat, likely due to higher nutrient availability and periodic inputs from recovering vegetation. Regression analysis confirmed a significant negative relationship between peat depth and microbial counts, whereas water table depth had no measurable effect, highlighting the stronger influence of decomposition stage and soil structure over short-term hydrological fluctuations. These findings emphasize the ecological importance of microbial communities in degraded tropical peatlands and suggest that microbial viability metrics offer a cost-effective, biologically relevant indicator for peatland health assessment. Integrating microbial parameters into restoration planning may enhance evidence-based strategies for managing post-fire tropical peat ecosystems.
