Nitrogen is the most abundant element in the atmosphere, however, most often deficient in agricultural lands. This research was an exploratory to get indigenous non-symbiotic nitrogen-fixing bacteria. Soil samples were collectedfrom rhizosphere of green beans. This study was aimed to determine the bacterial population of the three regions; screening, isolation and selection of free nitrogen-fixing bacteria. Antagonism and pathogenicity tests were performed to observe its potential for a biofertilizer product. The highest number of free nitrogen-fixing bacteria was found from forest soil sample of 2.5x 1011CFU/ml. Screening and isolation process has obtained 10 free nitrogen-fixing isolates. Then was selected into 4 isolates namely SNF4, SNF5, SNF7 and SNF8 according to the ammonia production test qualitatively. When an antagonism activity performed, there was no inhibition zone each other. The pathogenicity test did not show the pathogenic symptom. This study also showed that bacterial isolates obtained significantly affected the germination growth of green beans compared to controls. Possibility, bacteria of this type produced growth hormone for a plant. Strain SNF8 has shown the highest ammonium production then was selected for 16S rRNA identification. Similarity test of genome sequence of strain SNF8 had 99% similarity with Bacillus cereus.

Land use/land cover (LULC) is one of the important variables affecting human life and the physical environment. Modelling of change in LULC is an important tool for environmental management and for supporting spatial planning in environmentally important areas. In this study, a new approach was proposed to improve the accuracy and reliability of LULC simulation by integrating Markov cellular automata (Markov-CA) and landform-based models. Landform characteristics, positions and patterns influence LULC changes that are important in understanding the effects of environmental change and other physical factors. The results of this study showed that integration of Markov-CA and landform-based models increased correct rejection as a component of agreement and reduced incorrect hits and false alarms as components of disagreement for the percentage of the study area in each resolution (multiple of native pixel size). Correctly simulated hits as a component of agreement change also increased, even though nine of the 18 pairs of three-map comparisons showed a decline in this aspect. Meanwhile, misses as a component of disagreement change simulated as persistence also increased, although six of the 18 pairs of data showed a decline. Based on the overall three-map comparison analysis, there was an increase in the figure of merit (FOM) values after the Markov-CA and landform-based models were integrated, although six of the 18 pairs of data indicated a decrease in FOM values. This indicates improved results after integration of Markov-CA and landform-based models.

Soil degradation is the major environmental and agricultural production problem in the highlands of Ethiopia. The objectives of the study were to examine farmers’ use of grass strip and soil bund to minimize soil degradation, and effects of grass strip and soil bund on basic soil properties. Structured questionnaire survey and field observations were conducted to collect data on farmers’ use of grass strips and soil bund to minimize soil erosion, improve soil fertility and crop productivity. Simultaneously, composite soil samples were collected from croplands treated with both grass strip and soil bund, and the adjacent lands treated with soil bund only. The statistical result indicates respondents sex, marital status, educational level, erosion degree, access to conservation information, contact with extension workers, and trainings were significantly (P < 0.05) and positively affect the use of grass strips while livestock and land holding sizes were significantly (P < 0.05) and negatively affect farmers use of grass strip. The interaction of land management practices (grass strip and soil bund) and slope positions was significantly (P < 0.05) affects soil clay fractions and moisture, the highest amounts was observed at lands managed with grass strip situate at lower slope position. Similarly, soil organic matter, total nitrogen, available phosphorus, and cation exchange capacity were significantly (P < 0.05) influenced by the combined effects of land management practices and slope positions, highest quantity of these properties were observed lands managed with a grass strip and soil bund in lower slope position. Hence, integrated use of soil bund with grass strip has a meaningful contribution for selected soil property improvement that enhances soil fertility and crop productivity.

Returning and addition of organic material to soil is a key to protecting the soil, plants, and the environment. A study aimed to elucidate the effect of residual biomass application on some indicators of soil physical properties, abundance of earthworms and soil microbial activities was conducted in Kebun Percobaan (KP) Natar, BPTP Lampung from February to July 2017. The treatments were three types of crops biomass residues, i.e., maize stover, rice straw, and soybean stover (fresh or compost). The dosage rates were 0, 2.5, 5.0, 7.5, and 10 t/ha. The treatments were arranged in a randomized block design with three replicates. Upland rice (Inpago 9 variety) was planted after two weeks application of biomass residues treatments. The results showed that application of crops biomass residues improved bulkdensity and significantly increased soil water content at the high dose of biomass residues (7.5 or 10 t/ha). The amount and weight of earthworms with added of compost biomass was significantly correlated with soil water content (r values 0.491 and 0.376, respectively). The dose of biomass residues had a significant effect on soil respiration that the highest soil respiration was obtained in maize compost biomass treatment (at 12 weeks observation) was 31.7 and rice straw compost (at 8 weeks observation) which was 30.19 mg/hour/m2 C-CO2.

Large-scale land cultivation practices for agriculture which disregard conservation principles are resulting in land degradation problems in tropical regions. The differences of environmental condition become the main concern for determining proper strategies to overcome this problem. The present study aimed to evaluate the application of land and water conservation (LWC) practices in tropical agricultural watersheds. The conservation practices (in the form of regreening bare areas and construction of LWC structures i.e. small-scale dam, terrace and stone weir) were performed in a partnership scheme involving government, higher education institution, local inhabitant and private party. The result showed that the partnership approach made conservation activities possible in a shorter time and a lower risk of failure. Economically, it reduced the unit cost of the conservation structures construction up to 70%. We also assessed the dam performance for LWC purpose. The assessment indicated the dam can effectively increase soil water storage and control the river sedimentation. The use of local resources (community and materials for conservation structures) enabled the sustainable of LWC practices on a watershed scale.

Disposal of poorly managed cassava mill effluent often results in serious environmental degradation. A low-cost treatment option was developed to alleviate this rising concern prevalent among third world processors. Frustum-shaped ceramic filters produced by mixing different proportions of sawdust and activated carbon with equal amounts of clay, kaolin and sherds powder and sintered at 850°C was assessed in this study. The results indicated pollutant removal efficiency ranging from 6.5 to 98.1% with the best removal efficiency obtained for chemical oxygen demand (COD) [97.9 - 98.1%] closely followed by biochemical oxygen demand (BOD) [71.24 - 77.14%] while (24.13 - 30.72%) and (6.5 - 71.7%) were obtained for turbidity and hydrogen cyanide respectively. The filter with 12.8% of sawdust, 5.1% of activated carbon, 7.13% of kaolin, 3.6% of sherds powder and 71.3% of clay gave the best removal efficiency. A maximum flow rate of 0.0035 L/H (LPH) was recorded with a corresponding time of first drop of 216 minutes. The high removal efficiency observed for some parameters, locally available construction materials and wastewater reuse options makes this a viable option for cassava mill effluent treatment, however, further study is required to optimize this technique to meet wastewater permissible limits.

Environmental knowledge and perceptions of community govern the sustainable use and management of environmental resources. Developing countries such as Ethiopia has been facing serious environmental problems. In spite of the existing problems, little is known about public understanding and perception of environmental issues. Thus, the overall objective of this research was to assess community perception and knowledge of environmental issues. Interview was conducted using structured questionnaire. The collected data was coded, cleaned and analyzed using descriptive and inferential statistics. The result indicates, most of the community members believed that they have better knowledge of environmental issues but the evidence obtained from measured knowledge shows the reverse. The principal source of environmental information (local media broadcasting) had positive correlation with perceived knowledge, and negatively correlated with assessed knowledge and perception index of environmental issues. Correctly answered questions used in the evaluation of environmental knowledge were weekly associated (r < .2) with perceived knowledge and perception, which indicates the respondents lacks same concept on environmental issues. Perceived knowledge was negatively and significantly (P <.001) determined by age and educational levels of respondents. But, measured knowledge was negatively and significantly (P <.05) affects by age, childhood area, education and occupation when positively and significantly (P = .001) influenced by origin of residence. The perception of community was positively and significantly (P =.001) determined by respondent's age, childhood area, education and information source but negatively and significantly (P < .05) influenced by origin of residence and ethnic group. Generally, self-reported knowledge is not reliable source of information for environmental management decisions. So, stakeholders should strongly works on environmental awareness campaigns, engage students in outdoor activities, and training to improve factors negatively determined community's factual knowledge and perception of environment.

Exploitation of mining everywhere including gold mining in Bombana Regency, Southeast Sulawesi basically always showed two dilemmatic things. On the one hand, it was expected to have a positive contribution in increasing social welfare. On the other hand, it also aroused the risk society. This research aimed to express a variety of risks that happened as the effect of gold mining exploitation in Bombana Regency. This research used qualitative research, a variant case study that was meant to describe profoundly and holistically the effect caused by the mining exploitation. These findings showed that the exploitation of gold mining in Bombana Regency has the impact on the aspect of human and environmental life, namely ecological and socio-economic effects. The above-mentioned complexity of effect constructed a condition called risk society, covering the risk of socio-economic and natural material structures.

Application of fertilizers on previous crops can leave a residue so that it can be used for the next crops. It is necessary to know the extent to which these residues can affect the growth and yield of soybean crops. The objective of this study was to explore the effect of potassium fertilizer residues on growth and yield of soybean crops at third planting season (PS-III) on a vertisol. The research was conducted at dry season using a vertisol from Nganjuk, East Java. The experiment was designed using a factorial randomized block design with two factors and three replications. The first factor was the dose of potassium fertilizer (KCl) in the first planting season (PS-I) of rice, i.e. 0, 500, 1500, and 2000 kg potassium fertilizer/ha. The second factor was the dose of potassium fertilizer in the second planting season (PS-II) of soybean, i.e. 0, 50, 100, 200, and 400 kg potassium fertilizer (KCl)/ha. The soybean variety used was Sinabung. The results showed that fertilizer residues of planting season I and planting season II affected the growth component and yield component of soybean, but did not affect seed yield of soybean. There was no consistent increase on growth component, yield component, or seed yield of soybean with an increasing residual dose of potassium fertilizer of planting season I or planting season II. The residual treatment of 1500 kg potassium/ha at planting season I gave the highest number of branches per plant (2 branches) and seed weight per plant (3.13 g) of soybean. The residual treatment of 50 kg potassium/ha at planting season II gave the highest root nodule weight per plant of 0.10 g and the highest seed weight per plant of 3.33 g.

Human activity affects both natural resources and spatial land use, including its utilization as sand mining sites. Sand mines, as a pillar of building construction, have been over excavated in certain areas, which has impacted the environment. In this research, the purpose of this study was to determine a spatial allocation of the mining designation area that will not damage the groundwater flow. Therefore, it is imperative for understanding the depth of groundwater at the study site, understanding the direction of groundwater flow, and the impact of mining activities on groundwater based on the combination of geophysical and geological approaches to improve the current government policy. A geological-geophysics approach, vertical electrical sounding (VES), was followed at 12 different locations surrounding the Kertek District, which has a general geological formation of igneous volcanic rock sediment. The result of the geophysical measurements (possibilities) indicates the presence of shallow, medium, and deep groundwater aquifers, which tended to follow the slope direction to the south. This may be due to the unsaturated soil conditions as the geoelectrical measurements were taken at the beginning of the rainy season. Finally, the goals of this research were to integrate resources with spatial characteristics to allow proper resources management.
