Abstract

Changes in the condition of aquatic environment are now a major problem for the survival of every organism caused by changes in land use, human activities, and agriculture. This study aims to determine the structure of macroinvertebrate communities. In addition, this study also aims to conduct analysis on BMWP index and water quality testing using physical and chemical parameters. This study was conducted on tertiary channels in Songka Sub-District, Palopo City. Each station's data collection covered relative density, macroinvertebrates that were found were assessed using BMWP index, then they were calculated using ASPT index. The results of this study found 17 taxa classified in the class of gastropods, insecta, bivalvia, malacostraca, citellata, oligochaeta and hirudenia. The results of BMWP index modification analysis from all stations found that ASPT value was “quite-poor” and “bad”. It was indicated that in each station was mainly dominated by Oligochaeta worms and tolerant macroinvertebrates. Testing of physical and chemical parameters obtained DO value which belonged to class II of water quality. The low DO value caused high BOD value, which was classified in class III. The high value of BOD had an effect on the rise of COD value, the increase of COD value was caused by the high amount of organic and inorganic materials entering the water. PH value was relatively normal with the range of 6.3 to 6.8, temperature was in the range of 27.1°C to 28°C, the rise in temperature value was influenced by tree shade and the intensity of sunlight.Keywords: BMWP-ASPT, Community structure, Macroinvertebrate, Pollution, Tertiary channel

Abstract

Climate change and the erratic and uneven rainfall distribution are the causes of reduced water available in the soil for plant needs to the transpiration process. This study aimed to determine coffee transpiration rate on dry land with rain harvesting techniques during the dry season, transition season, and rainy season and the factors that influence it. This study used field observation and laboratory analysis with two treatments, i.e. a bench terrace as a control (P1) and an L-shaped silt pit (P2). The variables observed were soil moisture content, transpiration rate, soil water potential, leaf water potential, and microclimate, especially temperature and sunlight intensity. The results showed that the transpiration rate of coffee plants was significantly different in the two treatments. The highest transpiration rate was found in P2 as much as 13.17 mm week-1 or equivalent to 1.88 mm day-1 during the dry season. Application of the L-shaped silt pit (P2) increased soil moisture content compared to the control (P1). This increase was followed by an increase in soil water potential and leaf water potential, which could reach the highest values of 0.18 bar and 0.49 bar, respectively. The transpiration decreases with the change of seasons from the dry season to the transitional season and the rainy season. This decrease is caused by changes in the microclimate, especially the temperature and sunlight intensity. Both are the most variables that affect the rate of transpiration.

Abstract

Iron toxicity is a widespread nutrient disorder in lowland crop production, notably in lowland acid soils, swampy lands, coastal swamps and irrigated lowlands of Ultisols and Oxisols. It occurs only in flooded soils when the soil contains excessive amounts of iron. This excessive iron in soil has antagonistic effects on the uptake of many essential nutrients, poor growth and consequently yields reduction. The objective of this work was to evaluate the effects of different iron concentrations on growth characteristics and nutrient uptake of three pineapple clones (Ananas comosus L. Merr.). The experiment was held in a greenhouse of Research and Development Department of Great Giant Pineapple Company on December 2014 until March 2015. A randomize complete factorial design with two factors and four replications were used in this study. The first factor was pineapple clones (GP1, GP3, and F180) and second factor was iron concentration. Different amounts of iron as second factor 5 (control), 50, 100, 150, 200, 250 mg L-1 FeEDTA were added in the nutrient solution. The results showed that increase iron concentration was added in nutrient solution was reduced root length, number of roots, plant height, leaf area, root dry weight, and shoot dry weight significantly at p<0,05. Nutrient solution pH also decreased significantly with increasing concentration of iron in nutrient solution. Increased iron concentration in nutrient solution induced iron plaque formation on root surface and at the same time, Fe concentration on root tissues increased. However, higher iron concentration on nutrient solution results lower accumulation Mn in the roots. Excess iron had the same effect in reducing the absorption of P, K, and Ca on pineapple shoot. Whereas Fe and Mn uptake increased with increasing iron were added in nutrient solution. However, Mg absorption was not affected by the increase in the concentration of iron in the solution.

Abstract

Phosphorus that is absorbed by Al and Fe in Andisols makes it not available to plants. One of efforts to improve P availability in Andisols is application of agent containing phosphate biological solution. P. fluorescens bacteria have ability to dissolve P because it can produce organic acid that can absorb Al and Fe so that P can be available to plants. Mycorrhiza Arbuscular (MA) are fungi that have access to the source of P-organic by colonizing plant roots. The purpose of this study was to explore the role of MA and Pseudomonas fluorescens bacteria in increasing P uptake by maize grown in an Andisol. The results showed that the inoculation of P.fluorescens bacteria  and MA increased P uptake by 24% and improved maize growth  by 27.59%.

Abstract

The ability of sandy loam soils to hold water and nutrients is very low because of unstable soil aggregation. One of soil bacteria that can improve soil aggregates is Lactobacillus fermentum that is able to produce producing exopolysaccharide. The objective of this study was to explore the effect of application of Lactobacillus fermentum on improvement of chemical and physical properties of a sandy loam soil. Lactobacillus fermentum isolated from shrimp paste was used for soil aggregation tests. The treatments were P0 (450 mL distilled water), P1 (100 mL selected media + 350 mL distilled water with 1.67 x 104bacteria), P2 (200 mL selected  media + 250 mL distilled water with 2.13 x 105 bacteria,  dan P3 (400 mL selected  media + 50 mL distilled waiter with 3.54 x 106bacteria. The results showed that molasses give the best effect for bacterial growth compared with other media (coconut water, legen and sugar solution). Application of Lactobacillus fermentum significantly increased aggregate stability of the soil studied. In the initial analysis, soil aggregate stability was 0.48 mm (less stable. After incubation period up to 30 days the P1, P2 and P3 treatments increased aggregate stability by 1.27 mm (very stable), 1.43 mm (very stable), and 2.05 mm (very very stable), respectively. Lactobacillus fermentum also gave effect to the increase in organic matter, available P and K available. However, this bacterium did not give effect to an increase in available N and soil pH.
