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

The large number of old, damaged, or dead tea plants cause the plant population per hectare to be low that eventually decreases the productivity. Propagation using the transplantation technique is used for embroidery because it has the advantage of a shorter immature plant period and higher seed size so that it can compensate for the surrounding plants but the weakness of transplantation is low success rate. This study aims to 1) determine the morphological changes of root transplantation and biochemistry on TRI 2025 clone transplantation using cocopeat, husk charcoal, and moss, 2) determine the success rate of transplantation in each medium. This research was conducted in August 2018–January 2019 at the Pagilaran production garden, PT. Pagilaran, Batang, Central Java. Field experiments were prepared using a single factor Completely Randomized Environment Design (CRD). The factors tested were the type of transplantation media, namely the media of husk charcoal, cocopeat, and moss. Observations were made on transplantation root morphology, levels of glucose, sucrose, and total sugar in the transplanted stem bark and the concentration of auxin, gibberellin, and cytokinin in the transplant roots. The data obtained were then analyzed using variance and if there was a significant difference between treatments, the Duncan multiple distance test (DMRT) was continued at the 95% confidence level. The results showed that the type of media had no significant effect on the ability to form glucose, sucrose, and total sugar in the bark. The development of root morphology of cocopeat media was seen to be the highest. The ratio of cytokinin/auxin in cocopeat was the lowest but the highest levels of cytokinin and auxin were found in moss, while cocopeat had the highest level of gibberellin. The highest transplanting success rate was found in moss medium with 58.33%, cocopeat and husk charcoal media had the same success rate, namely 41.60%. Keywords: transplantation, biochemistry, media, success, TRI 2025

Abstract

The source of iron in waters can come from human activities that carry out activities such as waste disposal in household and industrial activities. Green mussels containing iron are very dangerous for the shells themselves and for human health if consumed in excess. This study aims to analyze the concentration of iron in green mussel meat, determine the safe limit of green mussel meat for consumption by humans, and calculate the value of bioconcentration factors. This research was conducted in the sea of Tanjung Mas, Semarang. Samples taken in the form of green mussels, sediments, and water were then analyzed for iron concentrations with Atomic Absorption Spectrophotometer. The results of the study showed that the range of iron concentration values in green mussels from July to November was 39–283,97 mg/kg. The range of MTI values for adults was 1.18–4.92, while for children the range was 0.24–0.98. The value of the bioconcentration factor of green mussels and water was 3271–24839, while the value of the bioconcentration factor of green mussels and sediments was 0.010–9.647. Keywords: bioconcentration, green mussels, iron, maximum tolerable intake, Tanjung Mas

Abstract

Spodoptera litura F. larvae (Lepidoptera: Noctuidae) are polyphagous insects that cause damages to many types of plantations and horticulture that need to be protected. One of environmentally friendly method to protect ecological balance is the use of botanical insecticides whose bioactive compounds come from plant extracts. This study used a mixture of two plant extracts from A. squamosa leaves extract and C. domestica rhizome exstract (the mixed of experimental extracts). The mixed of experimental extracts are synergistic so that they are more effective and need a lower concentration to cause the mortality of S. litura larvae than the use of a single extract. The aims of the research were to know the efficacy of the mixed of experimental extracts on the mortality of S. litura larvae and determine the value of LC50 and LC90 extract test on its mortality. The initial and efficacy test were conducted by bait dip into the mixed of experimental extracts. The mortality data were analyzed using ANAVA, then continued by Duncan test and Probit analysis. The results of this research showed that the mixed of experimental extracts were effective to kill S. litura larvae. The calculated result of LC50 and LC90 showed that the LC50 value of the experimental extracts on the second and the third instar larvae were 5.252 ppm and 10.559 ppm, respectively, and the LC90 value for both instar larvae were 11.124 ppm and 13.638 ppm, respectively. It could be concluded that the mixed of experimental extracts is effective in S. litura larvae mortality and more effective in the mortality of the second instar larvae than that of the third instar larvae. Therefore, this test extract mixture can be developed further in a greenhouse to evaluate the effectiveness in the mortality of S. litura larvae which can be used as an alternative to controlling S. litura larvae with an environmentally friendly material in farmers. Keywords: control, extract, mortality, Spodoptera litura

Abstract

The objective of this study was to analyze machining performance (characteristic and quality), as well as bonding quality of densified wood, and then compared to those of un-treated (control) wood and boron-treated wood. Characteristic and quality of machining properties were directly evaluated by qualified technician during processing, while bonding quality was evaluated through its shear strength. The results showed that densification employed was able to improve machining performance and bonding quality of the 5-year-old faster-grown teakwood. Compared to control wood and boron-treated wood, machining performances of densified teakwood are greater, while bonding quality increased by 18.79 and 26.86%, respectively. The surface became much fine and even, and has similar colour to older teakwood. Analysis hierarchy process (AHP) proves that densified teakwood is the best raw material for furniture manufacturing since its machining performances, appearance, colour, and bonding quality are better either than control wood or boron-treated wood. Keywords: AHP, bonding quality, densification, faster-grown teakwood, machining performance
