Abstract

Phytotoxicity of soil aluminum (Al), both directly to the plant growth as well as indirectly through the increase of soil potential acidity, is closely related to the occurrence of various soil soluble-Al species. Amongst them, Al3+ and monomeric-Al species are the primary causes of Al phytotoxicity in soils with high Al content. This study was aimed to evaluate the effects of soil amelioration with dolomite and base-activated lignite (BAL) on changes in soluble-Al species and other soil chemical properties, and vegetative growth of soybean (Glycine max Merr) on Ultisol of Jasinga (Al-dd 16,03 cmol(+)/kg). A green house experiment was conducted by applying a Completely Randomized Design with dolomite and BAL amelioration as the treatments, each with three levels of repectively 0, 1, 1,5 x exchangeable-Al and 0, 2,5, 5 tons BAL ha-1, and three replications. The ameliorants were incubated at field capacity of soil moisture content for one week before planting soybean for one month. Soil soluble-Al speciation was carried out using colorimetric aluminon method to determine concentrations of total soluble-Al, monomeric-Al, and polymeric-Al species. Monomeric-Al were further speciated into inorganic monomeric-Al and organic monomeric-Al species. The results revealed that only dolomite amelioration that significantly increased soil pH-H2O, pH-KCl, Ca- dd, Na-dd, and decreased exchangeable-Al concentration, except for those of all soluble-Al species that only showed a decreasing trend. Soil exchangeable-Al that was negatively and significantly correlated with soybean measure parameters were plant height, root length, total roots and shoots wet and dry weights, as well as Ca concentration. These results indicated that soil Al phytotoxicity evaluation could be relied on the result of routine analysis on soil exchangeable-Al concentration. Keywords: exchangeable-Al, inorganic monomeric-Al, organic monomeric-Al, polymeric-Al

Abstract

Water-quality monitoring using macroinvertebrates has been developed by several countries to determine their water qualities. Meanwhile in Indonesia, water quality monitoring has not been developed to adapt to Indonesia’s natural conditions. Some researchers use the existing biotic indices such as FBI, LQI, SIGNAL, and others. Therefore, this study aims to determine the status of water quality using several biotic indices and to compare the sensitivity and feasibility of indices on monitoring activities using simple matrix and Pearson correlation test. The interpretation results of FBI, LQI, and Singscore to determine water quality on each station in Brantas, Opak, Progo, and Cileungsi Rivers were different. The Pearson’s correlations test showed that the sensitivities are different between rivers. Those results are affected by the river conditions and also the activities around the rivers which release the pollution into the river. The FBI index showed the greatest score number of sensitivities among the other indexes. Keywords: macroinvertebrate, monitoring, river, sensitivity

Abstract

There are many innovations in wet noodle processing with color variations. One of wet noodle processing innovations is the use of natural dyes such as fruit or vegetable dyes. The essence of red chilies can be used as a natural dye for wet noodles. Natural dyes dissolve easily during the boiling process, therefore color retention agents can be added in the processing and expected to be able to retain the red color of chilies in wet noodles. This study aims to determine the effect of adding color retention agents on physicochemical characteristics, namely moisture content, color resistance, texture, and vitamin C content in wet noodles. The method used in this study was a completely randomized design (CRD) with 5 treatments of color retention agents each with 4 repetitions. The treatments applied were T0: without the addition of a color retention agent, T1: ascorbic acid (C6H8O6), T2: citric acid (C6H8O7), T3: magnesium hydroxide (Mg(OH2)), and T4: magnesium carbonate (MgCO3). The test results were analyzed using Analysis of Variance (ANOVA) and if there is a significant effect at the 5% significance level, then proceed with the Duncan Multiple Region Test to determine the differences between treatments. All data analyses were calculated by using a computer program SPSS 21.0 for windows. Data from the test for vitamin C content were analyzed using Microsoft Excel through graphical analysis. The results is addition of color retention agent treatment to wet noodles with natural dyes from chilies had a significant effect on the color resistance, moisture content, texture, and vitamin C content of wet noodles. T4 wet noodle is the best wet noodle treatment in maintaining the red color with the physical characteristics according to SNI. Keywords: color retention agents, noodles, red chili

Abstract

Fish is one source of high protein and included a commodity which is easily to decay. The way to inhibit the decay process of fish is fumigation. One of the smoked fishes that is often consumed by Gorontalo people is smoked Roa fish (Hemiramphus sp.). Smoked Roa fish is processed with traditional way through burning using woods as the fuel. Simply or conventionally fish processing like that has several flaws such as less protected of the sanitation aspects in the processing protocol. In order to improve the traditional processed product of Gorontalo, that is a smoked Roa fish, a new breakthrough in making smoked Roa fish was made by using the liquid smoke method. Liquid smoke contains compound of phenol and organic acids that are antibacterial and antioxidant compounds. The purpose of this research is to evaluate the effect of using different fumigation methods on organoleptic quality (appearance, smell, taste, and texture) of smoked Roa fish. The fumigation methods used were fumigation with liquid smoke and fumigation with traditional method. This research used a completely randomized design with 2 treatments and 3 times of replications. The results showed that liquid smoked Roa fish were preferred by panelists, compared to traditional smoked Roa fish. Liquid smoked Roa fish had a bright appearance, the smoke color was spread evenly (uniform), the smell of soft smoke, delicious fish taste, and hard texture that were different from traditional smoked Roa fish which appearance tended to be dull, the color of the smoke was not evenly distributed, the smoke taste in the fish was also quite sharp. Liquid smoked Roa fish also had a lower water content than traditional smoked Roa fish. Statistical tests showed that the fumigation method had a significant effect on the smell and water content of smoked Roa fish. Keywords: hedonics, liquid smoke, organoleptic, Roa fish, traditional fumigation

Abstract

The genus Fusarium sp. is a pathogenic fungal for many cultivated plants. The bacteria isolated from monkey cup (Nepenthes sp.) fluid possess the ability to produce hydrolytic enzyme, such as chitinase which can be utilized to inhibit the growth of mycelia of pathogenic fungi. The aims of this study are to isolate bacteria from monkey cup liquid, to test their abilities to produce protease, chitinase, and cellulase, as well as their abilities to inhibit Fusarium. The bacteria were isolated using serial dilution method on Reasoner’s 2A agar medium. Enzymatic activities of bacterial isolates were determined by inoculating them on tested medium supplemented with casein protein, chitin, and cellulose, whereas their antifungal activities were assayed using a direct confrontation method between tested bacterial isolates and pathogenic fungal on Malt Extract Agar medium. Molecular identification of bacteria with antifungal activity was performed by analyzing the 16S rRNA gene sequences. Isolation process of bacteria from monkey cup fluid resulted in 99 bacterial isolates with the ability to produce either protease, chitinase, and/or cellulose enzymes. A total of 37 bacterial isolates were capable of producing at least two hydrolytic enzymes. Antifungal assay of those bacteria showed that as many as 25 isolates have the ability to inhibit the growth of Fusarium sp. Based on the analysis of 16S rRNA gene sequences revealed that those isolates were closely related to three Burkholderia species, namely B. arboris, B. contaminans, and B. rijonensis. Keywords: antifungal, Burkholderia, chitinase, cellulaseN, epenthes, protease

Abstract

Land use change is one of the causes of the decreasing of hydrological function that affects the hydrological response of a watershed. Planning of watershed management needs to be conducted to improve the hydrological function of the watershed. This study aims to determine the hydrological response in supporting watershed management planning in Opak Hulu Watershed. This research was conducted using the Soil and Water Assessment Tool (SWAT) hydrological modeling. The method used included data collection, processing of input data, running of SWAT model, calibration, validation, and the decision of the best watershed management scenarios. The results of the analysis of land use changes in the Opak Hulu Watershed in 2012–2017 had a significant increase in mixed upland agriculture (3.21%) and shrubs (1.43%). Meanwhile, open field (2,31%) and dry land agriculture (1.71%) decreased significantly. Based on the analyzed hydrological scenario, Soil and Water Conservation techniques can decrease the surface runoff and increase the lateral flow and base flow. The scenario is able to decrease the surface runoff by 542.22 mm (27.09%). It increases lateral flow and base flow by 321.82 mm (13.15%) and 797.28 mm (18.32%), respectively. The best watershed management planning with Soil and Water Conservation technique is able to reach Annual Flow Coefficient value to 0,33 (moderate) and 69,85 (moderate) for Flow Regime Coefficient.

Abstract

Rice yellow stem borer (YSB, Scirpophaga incertulas Wlk) is one of the most damaging rice pests in Indonesia, especially in rice growing centers in West Java. Because there is no source of resistance genes in rice or its close relatives, resistant improvement by genetic engineering is one strategy to obtain resistant rice cultivar. Previously, the cryIB::cryIAa fusion gene from Bacillus thuringiensis has been introduced into the Rojolele variety to obtain 6 transgenic rice events resistant to YSB (X22, U10, W3, Y7, Q20, and P8) and has been tested for resistance in greenhouses. This study was aimed to evaluate the transgenic rice productivity carried out in a confined field trial in field station belonging to the Center for Rice Research in Sukamandi, Subang, West Java. The procedure for the field testing followed the 1998 Guidelines for Biosafety Testing of Agricultural Biotechnology Products: Plant Seri by the Ministry of Agriculture. The parameters observed were agronomic characters (plant height, number of tillers, and number of panicles) and yield components (number of filled grains per panicle, number of empty grains per panicle, panicle length, and weight of 1000 grains). The yield was also measured by dry grain yield. The results indicated that the performance were varied among the 6 events tested. Rice events X22, W3, Y7, and P8 showed agronomic characteristics and yield components resembled Rojolele varieties, and performed well under field condition. X22 and W3 showed closest resemblance to Rojolele in terms of yield potential. Keywords: confined field trial, cryIB::cryIAa, production, rice yellow stem borrer, rojolele rice, transgenic
