Both, biotic and abiotic factor is the most important problem for agriculture in Indonesia. Biotic factor such as plant disease could decrease yield till more than 50%, while abiotic factor such as soil contamination could decrease yield till more than 30%. One of choice to overcome this problem is using bio-phytoremediation method. This method combine remediation using plant (phytoremediation) and remediation using microbe (bio remediation). This study was aimed to determine the effects of bio-phytotemediation method using Paraserianthes falcataria which infected by mycorrhizal fungi to overcome Phytophthora brassicae, the main clubroot disease on Brassica juncea, in Pb contaminated soil. We also aimed to know the influence of the method to absorb soil Pb using Paraserianthes falcataria. The research was conducted in the Mycology Faculty of Agriculture, University of Brawijaya from March to October 2015. The research used Completely Randomized Design with 6 treatments and 4 replications. Parameter observation in this research were: 1) Intensity of clubroot disease; 2) Growth of B. juncea; 3) Population of mycorrhizal spores in soil, 4) Mycorrhizal infection inside plant cell; and 4) Pb content of soil and plant tissues. The results was showed that mycorrhizal has significantly effects to decrease clubroot disease intensity. But, mycorrhizal has no significantly effect to the plant growth, including stem length and leaves number. The number of mycorrhizal spores in the soil after 35 days application was increases, and the percentage of infection in the roots of B. juncea and P. falcataria was fluctuated. The application of mycorrhizal can decrease Pb content in the soil and increase Pb content in P. falcataria.

This research studied the application of multitrip vehicle routing problem with time windows (VRPTW) on the problems of the tourist routes in Banyuwangi. The problems of ordinary VRPTW has only one route to the finish line that will be targeted with specific time limits while the multi-trip VRPTW has several tourist routes and one central point as the reference point for determining the route of the tour as well as the deadline for each tour. Genetic algorithm used to solve this problem because it can overcome the problem of combinatorial effectively and efficiently, moreover it can reach solutions globally so that it can produce the optimum solution. Chromosome on the Genetic Algorithm represents the permutation of the overall tour. After decoding there are three chromosome segments created, where each segment represents a visit of tourist attractions in one day. This research provides the optimal result i.e. a solution route with the shortest commute time and a fast computing time so it is very helpful in determining the route of the tourist trips with the closest mileage based on their places to stay (centre point).

A contaminated soil by tin usually is a big problem in Indonesia. Uniformity is essential for processing soil at a normal quality and to ensure conformity to specify clean up levels. Revegetation efforts were carried out by using rubber and jatropha combination which infected by arbuscular mycorrhizal (VAM) fungi applied using the soil drive nutrient (SDN) method showed good result in the previously research.This research purposes to know the effectivity of soil drive nutrient (SDN) method to promote the growth of soybean plants (Glysine max L.) in tin mining soil. The results showed that the cropping pattern and dose of mycorrhizal gave effect on soybean growth, especially on the trunk diameter. Result also showed that mycorrhizal infection on soybean roots significantly influenced by the SDN method and dose of mycorrhizal that applied. Both of these are expected to have a positive impact on soybean production and resistance to environmental stress and disease attack. Viceversa, height and number of plant leaves untill 28 days were not affected by the SDN method and the dose of mycorrhiza applied.

Speciation of Chromium (Cr) is very important because of the toxicity of these metals depending on the oxidation number and its concentration is very low in the water system. Chromium occurs in the environment primarily in two valence states, trivalent Cr(III) and hexavalent Cr(VI). Chromium (III) is an essential micro-nutrients for the human body, while the Cr(VI) is highly toxic and carcino-gennic. Chromium(VI) in the water can be analyzed by spectrophotometry with diphenylcarbazide as reagent on pH=1 at maximum wavelength of 540 nm. The experimental result show that Cr(VI) can be analyzed using diphenylcarbazide in the concentration of 0.0015% and H3PO4 solution as acidic in 0.03 mol/L. The absorbance was measured at minutes 5 after preparation. There is interference from ion Fe(III) at least 6.0 ppm and this interference can be overcome by using 0.3 % NaF solution. The limit of detection of this method is -samples, mix of Cr(III) and Cr(VI), can be analyzed by using this method without oxidation by KMnO4 solution. While Cr(III) in the artificial samples, mix of Cr(III) and Cr(VI), can be analyzed by using this method via oxidation by KMnO4 solution in the acidic media (H2SO4), the result of this analysis is the total concentration of Chromium. The concen-tration of Cr(III) can be calculate via subtract the total of Cr concentration by concentration of Cr(VI).Keywords: speciation, Cr(III), Cr(VI), spectropho-tometry, diphenylcarbazide, Fe(III), interference.

Clungup Mangrove Conservation (CMC) is a location managed by Bhakti Alam Sendang Biru Organization. Mangrove management activities were carried out continuously starting from mangroves clearing in 1998 until it is all used up and started replanting when people found it difficult to catch fish. Mangroves are plants which lived at maximum subsiding tide point to maximum rising tide point area, with mud as its substrate. For other organisms, mangroves used as shelter and foraging place. One of those organisms is birds, birds can be used as bioindicators of environmental quality because it has a sensitivity to environmental changes. This study divided into 4 stations based on mangrove vegetation, the results observed were for Shannon Index at 1.99-2.3 and Margalef Index at 3.5-3.8 for morning observations. While for afternoon observation resulted as Shannon Index at 1.2-2.2 and Margalef Index at 1.8-3.9. The main focus is some water birds such as Ardeola speciousa, Todiramphus chloris, Aldeco coerulescens, Butorides Striata, Todiramphus sanctus and Charadrius javanicus which shows that mangrove ecosystems provide a function of nursery ground for fish and feeding ground for birds.

Extraction of silica has now been developed as one of the additional nutrients in the soil. This silica extraction technology is developed from materials that are no longer used as an example of rice husks. As a result of the extraction of rice husk silica is used to nourish the rice plants themselves. The addition of plant nutrients can be optimized by using an encapsulation system. The process of nutritional encapsulation is expected to optimize the absorption of nutrients in the soil in slow reaction. This inhibitory process can also be supported by the use of nutrient remobilization. So the purpose of this research is to obtain the optimum result of silica extract from rice husk and to know the characteristics of capsulation result of silica extract produced. As for this research using the addition of KOH so that this research method using Randomized Block Design (RBD) with KOH 2.5%, 5%, and 7.5%. The analyst has performed mass equilibrium analysis, water content of the material, and SEM analysis for physical analysis. In this study showed that with the addition of 5% KOH treatment to be the best treatment in this study that produced as many as 4.5 grams. Furthermore, the sample was treated with liquid nitrogen as an encapsulation medium. The result of the research showed that the silica value contained in the extract yield on KOH 5% by 19.4% while in addition KOH 7.5% silica content of 21.8%. This shows the highest value of yield that is in the addition of KOH of 5% but the silk content of the most that is in the addition of KOH of 7.5%.

Heavy metal pollution in aquatic ecosystems has become one of the primary environmental problems. Cr(VI) is one of the most toxic and carcinogenic heavy metal pollutants. The degradation of aquatic ecosystems due to the Cr(VI) pollution usually occurs slowly, but the impact is accumulative. Hence, an awareness of the pollution often occurs when the impacts have already in the acute or chronic level. Therefore, the technologies to monitor and to solve the Cr(VI) pollution are critically important. The application of biological resources emerges as an alternative technology to solve the problems. This study analyzes the utilization of biofilm as a biomonitoring agent and a biosorbent to monitor and to immobilize Cr(VI) in the aquatic ecosystems, respectively. The development of the biofilm as a biomonitoring agent is conducted through the investigation of Cr(VI) concentration in the biofilm and the surrounding river water, while the utilization of the biofilm as a biosorbent is developed through the analysis of Cr(VI) adsorption characteristics to the biofilm. The results of this study reveal that the concentrations of Cr(VI) inside the biofilms are hundreds of times higher than the surrounding river water. The biofilms seem to accumulate the Cr(VI) from the surrounding river water through a physicochemical process. According to the result of this study, biofilms can become a promising biological agent to monitor and to immobilize Cr(VI) in the aquatic ecosystems.Keywords: Biofilm, Biomonitoring, Biosorption, Cr(VI), Water Pollution

The diversity of activities along the Balangan river causes waste disposal, which contributes to an increase in pollution load in the Balangan river. The purpose of this study is to predict the water quality conditions spatially using IDW method, and to determine the relation among distance and water quality status. In the whole location, the results showed that the pollution load capacity was exceeded, the levels of BOD5, COD, Sulfide, Iron, Manganese and Phosphate were parameters that had exceeded the quality standard. The pattern of water quality decreases in the downstream area, especially at BOD5 and COD levels. While the levels of TSS, Nitrate, Nitrite, Ammoniac, Iron, Manganese, and Detergent showed a temporary pattern of decline and showed an increase again. Phosphate levels showed a temporary increase and then there was a decrease again afterwards. Based on the sampling location the distance between the starting point and end point is 12 km, the prediction of the distribution of water quality using IDW shows that at a distance of 1-6 km shows a stable water quality pattern, a distance of 7-10 has improved water quality and 11-12 has decreased water quality.
