Publisher : Natural B, Journal of Health and Environmental Sciences

Kenaf is a fiber plants of the family Malvaceae. KR 11 is a high yielding kenaf variety which is resistant to drought stress. Mutations by EMS at several species known to increase resistance to drought stress by accumulation of osmolite. In this research, physiological testing on 5 mutants to determine the effect of the mutation on the drought stress response of kenaf KR 11was conducted. Experiment were done by comparing the physiological accumulation of proline in normal and drought stress conditions. The plants were watered every 3 days for 14 days with 100% of field capacity as normal conditions and 25% field capacity as drought stress. The results showeddifferences inthe pattern ofprolineaccumulationbetweencontrolandmutant in normal and drought stress condition. While control KR11 increased the accumulation on drought condition, mutants showed decreasedprolin content under conditions of stresswith varying decreasing levels. The mostsignificant pattern ofproline accumulationcompared with control, is shownby themutant4and5. Prolin accumulation pattern is controlled by the proline metabolism control genes, P5CS and ProDH and its feedback regulation. Alteration of this pattern is most likely an effect of mutation induction on the mutant sample.

The problem of food insecurity has long been the focus of attention and is very closely related to the problem of poverty in which the two are interrelated phenomena that have a causal relationship. Food insecurity and poverty is a package that is always the problem faced by the government both central and local government, especially in Sampang. Spatial regression models that have been described in general a univariate spatial model, in which the observations have only one response variable that depends on the location of the observation. Geographically Weighted Multivariat Linier Model a multivariate regression models were used to spatially resolve the influence of spatial heterogeneity caused by differences in the conditions of the location with another location. The purpose of this study was to establish Geographically Weighted Multivariat Linier Model (GWMLM) with a weighted cross – variogram gaussian on the problem of food insecurity and poverty in Sampang. Food insecurity and poverty is a phenomenon of spatial heterogeneity. Based on the 10 sampled villages gained influence the percentage of households without access to electricity (X1), the percentage of main roads are adequate (X2) , the number of health facilities (X3) , and the percentage of malnutrition children (X4) against food insecurity and poverty differently in each location.

Along with population growth, the need for clean water is increasing. The availability of clean water is starting to decrease due to the decline in quality and quantity of water in the environment. Water quality degradation can be caused by water pollution from industrial waste disposal. One of the parameters to measure the level of pollution is the biochemical oxygen demand (BOD). Beside titration, biosensor method is a method developed to measure the BOD. The purpose of this study is to design a microorganism-based biosensor that can be used to measure levels of Biochemical Oxygen Demand (BOD5) using a microelectrode transducer with Pseudomonas putida and Pseudomonas fluorescents as bioreceptor on phenol wastes. BOD concentration was controlled by adding phenol in water with concentration of 0 mg/L, 50 mg/L, 100 mg/L, 150 mg/L, 200 mg/L and 250 mg/L. BOD concentration as measured by using titration method and developed biosensor. Experimental result shows that the potential of the biosensor linearly correlated to the concentration of BOD in water. Membrane surface area does not contribute any effect to the output potential of the biosensor. We can conclude that both Pseudomonas putida and Pseudomonas fluorescents can be use as material for measuring BOD concentration in water.

The purpose of research is to detect optimum concentration of immobilization of specific anti protein cow’s milk with 208 kDa molecular weight’s (anti PSS 208 kDa) by utilizing QCM (Quartz Crystal Microbalance) sensor. QCM sensor had been coated by polystiren solution of 5% which is heated until 200 ◦C. During measurement, QCM sensor place on data accuisition and QCM-Box measurement. 30 µL Anti PSS 208 kDa with concentration varied between 200 mg/L up to 1400 mg/L was dropped to QCM sensors. Frequency changes were recorded as a function of concentration of anti PSS 208 kDa. The frequency changes due to presence of anti PSS 208 kDa deposited on the surface of QCM sensor were not spontaneous, but takes time to reach steady state. As the concentration of anti PSS 208 kDa increased, so is the frequency change until it reaches saturation point at 1000 mg/L. The mass percentage of anti PSS 208 kDa deposited on QCM sensor surface is decreased with increasing anti PSS 208 kDa concentration. Therefore optimum immobilization concentration of anti PSS 208 kDa is define on frequency changes at first saturation point, that is at 1000 mg/L concentration namely 267 ± 5 Hz

Some plants that have wood economically value are found at Meru Betiri National Park, such as nyampuh (Litsea monopetala (Roxb.) Pers.), bayur (Pterospermum javanicum Jungh.), gempol kethek (Lophopetalum javanicum (Zoll.) Turcz.), suren (Toona sureni Merr.), sapen (Pomentia tomentosa T. & B.), manting (Eugenia cymosa Lamk.), pluncing (Spondias pinnata (L.F.) Kurz.), mahoni (Swietenia macrophylla King), and bungur (Lagerstoemia speciosa Pers.). Anatomically, wood has specific and unique structure. Wood is a secondary xylem that consist of tracheary elements such as vessel and tracheid, fibers such as fiber-tracheid and libriform fiber, and parenchyma cells (ray system). The pattern of wood section is affected by intrinsic factors. Wood was sectioned in 2X1 cm² in measurement and then it was boiled during 1 hour, after that it was immersed in mixed solution glycerin and absolute alcohol (1:1) during several weeks until the wood smooth adequately to sliced. Wood was sliced by sliding microtome 20-25 µm in thickness, and then it was placed on the objectglass that contain glycerin and covered by coverglass, after that it was observed by microscope. There was anatomically variation of wood samples that observed, involved trachea and tracheid width, also schlerenchyme fiber length. Vessel of nyampuh is the biggest in diameter (35±4.7 µm), and parenchyma ray of suren is the longest in length (70±9.3 µm) among other species.

Research has been done on the spread of contaminants in the Supit Urang landfill, the city of Malang. The research was done in April 2013 - January 2014 in the area around Supit Urang landfill. The research purpose to determine the presence of contaminants in the Supit Urang landfill and distribution patterns. This research was begun by doing a data correction, consists of diurnal correction and IGRF correction so that got the total magnetic anomaly. Then, did reduction to the pole and upward continuation so that got the residual magnetic anomaly value ranging from -800 nT to 1100 nT. The results of data processing showed that contaminants in Supit Urang landfill accumulated on the inside of the landfill and then spreads in all directions with a depth of seepage reaches 25 meters. The spread of these contaminants are more inclined to the south because there is a river which is the discharge path of leachate from landfill to the river in the area. The results also showed the structure of the subsurface Supit Urang landfill dominated by sedimentary rocks such as sandstone, clay, tuff, tuff breccia and breccia. Based on the chemical test results, it showed contaminants in landfill is suspected to be leachate with susceptibility value between 0.0001 Wb/Am to 0.001 Wb/Am. Leachate from landfill contains some heavy metals with different concentrations, such as Cobalt (Co) 0.38 mg/L, Copper (Cu) 0.58 mg/L, Iron (Fe) 6.5 mg/L, Lead (Pb) 5.4 mg/L and Zinc (Zn) 4.8 mg/L.

Radiotherapy is an alternative treatment for cancer patients to inhibit and destroy cancer cells due to the ionization. Gamma rays ionize not only cancer cells but also damage healthy cells due to precence of free radicals produced by ionizing gamma rays when interacting with biological material. The decrease in blood cells as ie hemoglobin, leukocytes and platelets caused free radicals can be minimized by administering antioxidant vitamins C and E. This study was conducted to determine the effects of gamma radiation exposure to the decrease in hemoglobin blood cells, leukocytes and platelets of mice after administration of a combination of antioxidant vitamins C and E in five variations, namely 10 mg dose: 1μl, 15 mg: 1.5 μl, 20 mg: 2 μl, 25 mg: 2.5 μl, 30 mg: 3 μl. Exposure of gamma radiation was given fractionation ranging from 200 rads to 1000 rads. Blood was taken from the heart for hemoglobin, leukocytes and platelets tests. The results showed that the administration of vitamins C and E may reduce the decline in hemoglobin levels, leukocytes, platelets resulting from exposure to gamma radiation when compared to the control group or without vitamin.
