Mining activities can have negative impact on the environment causing water and soil pollution. Chemical physical properties also biological environment to change condition to be low organic matter, low soil pH, low water holding capacity, inadequate nutrient and acid generating material. Coal mining land is acidic cause of sulfur oxidation reaction with rainwater to produce sulfuric acid so that acidic of the soil condition. Biotechnology study is a wise effort to solution environment pollution with Sulfate Reducing Bacteria (SRB) as bioremediation agents. SRB can contaminate sulphate with an indicator pH increase which indicates of a SRB population increase and sulfate content decrease. This study aims to obtain a SRB isolate as potential a bioremediation agent for ex-coal mining soil. This study is experiment research with SRB isolate as treatment, that obtained from ex-coal mining soil at PT. Bukit Asam Tanjung Enim, South Sumatera. The result of this study obtained 10 (ten) SRB isolated a from the bacterial isolation stage. Ten SRB isolates were selected, obtained by five SRB isolates that have black criteria with the number of colonies approaching the same so that it has the potential as a bioremediation agent for ex-coal mining soil. SRB isolates P10T1R2, P9T2R2, P6T1R3, P5T1R1 dan P2T1R2 were potential tested on ex-coal mining to increase pH and reduce sulfate. The P5T1R1 SRB isolate has the potential to reduce sulfate at a concentration of 3561 ppm. Furthermore the result of the 5% LSD test show that this isolates is significantly different that other isolates so that it can be used as bioremediation agent.

This study examined factors influencing the adoption and infusion of green practices by manufacturing companies in Ogun State, Nigeria. The study adopted a cross-sectional and descriptive survey research design. Area-based technique in which multi-stage sampling technique was used to select 321 employees of medium and large-sca2le manufacturing firms in Ogun State, Nigeria. A semi-structured questionnaire was used for data collection. The data were analysed using factor analysis and multiple regression. An examination of the research objective revealed two technological factors which are a combination of adoption cost and complexity (as the first factor) as well as the combination of relative advantage and compatibility (as the second factor) that influence green practices adoption in every manufacturing company. Also, five organizational factors (regulatory support, organizational support, quality of human resources, environmental factors and customer pressure) influence green practices adoption with eigenvalues greater than 1 and Cronbach’s alpha greater than 0.700. Test of hypotheses revealed that compatibility (β =0.191, t = 2.033; P < .05), organizational support (β = -0.303, t = -3.595; P < .05), environmental factors (β = -0.219, t = -3.199; P < .05) significantly independently predicted infusion of green practices while, adoption cost (β =-0.087, t = .909; P >.05), complexity (β =0.022, t = .264; P < .05), relative advantage (β =0.072, t = 808; P > .05), quality of human resource (β =0.125, t = 1.364; P > .05), government support (β =-.031, t = -464; P > .05), regulatory support (β = -.118, t = -1.562 P > .05) and customer pressure (β = -.119, t = -1.557; P > .05) had no significant independent prediction on infusion of green practices. The findings of the study were discussed within the existing literature and recommendations were provided for policy intervention.

Vacuum residue well know as waste product from refinery crude oil refinery and need a further process to improve its quality. In this study, a catalytic cracking process of vacuum residue in electromagnetic field is investigated using Fe2O3/Al2O3 as catalyst. The optimization process is conducted by combination vacuum residue and catalyst in the ratios of 1:5, 1:6, 1:7, 1:8, and 1:9 under 75 min of reaction time, 400oC and 10A applied current . Liquid product analyzed using gas cromatografy mass spectrometry (GCMS). The result showed that there were a formation of, p-xylene, paraffin, and naphthalene detected, meaning it was successfully cracked. In the retention time 4,3min, identified p-xylene which aromatic groups about 11,38%. Not only 1,04% paraffin identified in the retention time 7,76 min. But also, naphtalene about 3,28% was identified in the retention time 7,80 min.

Forest and land fires has become one of the most difficult natural disaster to handle, forest and land fires happened every year all around the world, and become one of the many cause of global warming and climate change and if it is not resolved immediately then it will harm all of the living beings on this earth. Forest and land fire in Indonesia happened nearly every year, the first biggest forest and land fires ever recorded in Indonesia happened in 1998-1999 which harm many parties, especially the ASEAN, since then, forest and land fires in Indonesia nearly happened every year whose impact neighboring countries like Singapore and Malaysia, In 2015 forest and land fires can be said quite large and once again affects neighboring countries, until Indonesia neighboring countries like Singapore want to try to help extinguish the forest and land fires in Indonesia.

Non-timber forest products (NTFPs) are a great potential in the forest, one of which is in the Saleh-Sugihan River Peat Hydrology Area (PHA). More optimal utilization of NTFPs is obtained with more diverse types of NTFPs, so it is important to know the diversity and potential of commodities in peatland areas for further development based on NTFPs. The research had been conducted from May to July 2018 in the PHA area of the Saleh-Sugihan Rivers, choosing Pangkalan Lampam District, Ogan Komering Ilir Regency, South Sumatra. Research sites include the villages of Air Rumbai, Deling, Lirik, Pangkalan Lampam, Rambai and Sukaraja. The research method is used by sampling, observation and interview methods. Determination of selected commodities uses analysis of Non-Timber Forest Products / NTFPs (Regulation of the Minister of Forestry of the Republic of Indonesia, 2009). Based on the results of the research that has been carried out, it is concluded that the leading commodity from the Peat Hydrology Area is swallow, paddy and fish, while the main commodity in Pangkalan Lampam sub-district is buffalo and purun. Leading commodity types of swallow, paddy, fish become NTFPs which are prioritized to be developed at the PHA River Saleh-Sugihan location, so that their development will be more focused and directed, in order to improve the regional economy.

Marine environment reported has been decreasing in water quality caused by microplastic. This micro-particle generated from contamination of ultraviolet light with plastic debris on the environment. Microplastic has been found in several marine environments and made some problems especially for marine ecosystem, such as beach, river and sea. This article described microplastic source, technique for detection and analysis of microplastic in marine environment, physicochemical of microplastic including physical properties such as particle size, particle shape, crystallinity, etc and chemical properties of microplastic (i.e. toxicity and chemical compounds). This article discusses the impact of microplastic for environment and human health. Thus, this article has described the systematic information about microplastic in the marine environment.

Activated carbon prepared from rubber (Havea brasiliensis) seeds was used to remove methylene blue from aqueous solutions. Adsorption studies were conducted to evaluate the effect of contact time and amount of carbon active on the removal of methylene blue at temperature of 25oC. The equilibrium adsorption data of methylene blue on activated carbon were analyzed by Freundlich and Langmuir isotherm model. This research compare between conventional heating and microwave heating, various of mass adsorben and various of radiation time. Carbon was activated by using various KOH using Conventional and Microwave Heating . The best adsorption was shown in Impregnation Ratio 1:1,5 carbon and KOH which dried using microwave heating.It was 3,486 mg/g was qe value. The percentgae of adsorption was 69,72%. The best result of adsorption MB using various of mass adsorben was shown in 0,4 gr. The absorption kinetic models were predicted by pseudo-first-order and pseudo-second-order. The pseudo-second-order kinetic and pseudo second order model was fitting equilibrium adsorption data. The results of adsorption methylene blue on aqueous solutions shown that rubber seeds as carbon active can be used as material for adsorption.
