Abstract

One  of  the  common  diseases  of  shallot  is  moler  disease,  caused by Fusarium oxysporum. This disease causes some damage to the plant. The attack mechanism of Fusarium oxysporum is by penetrating, colonizing, and multiplying in the root area, then parasitizing and inhibiting  the  process of  carrying  water  to  whole  parts  of  the  plant. Biological   control   of   moler   diseases   using   fungal   antagonist   has developed considerably in recent years. Fungal antagonists play a significant role in controlling plant pathogens and moler diseases caused by Fusarium oxysporum, such as Trichoderma harzianum and Acremonium variecolor. A series of experiments in field conducted to assess the comparison of ability between Trichoderma harzianum strain MGQ2   and   Acremonium   variecolor   strain   130360   in   effectively controling moler in shallot.

Abstract

Macrozoobenthos has an important role in the waters. The river is one example of a water body where macrozoobenthos can be used as an indicator of water pollution. This study aims to calculate the community structure of macrozoobenthos and the water quality in the Ogan River around Baturaja City. Sampling was carried out by purposive sampling method in 5 stations, in which each station had 5 sampling points determined based on differences in microhabitat, namely stonny, gravel, sandy, and litter conditions around the edge of vegetation. The results revealed that macrozoobenthos found in the Ogan River consisted of 6 classes (i.e., Bivalvia, Crustacea, Gastropods, Insecta, Oligochaeta, and Turbellaria), 12 orders, 21 families, and 30 genera. The density of macrozoobenthos species ranged from 598 to 1367 ind/m2. The diversity index value in the Ogan River around Baturaja City ranged from 1.117 to 2.22 with a moderate category. In addition, the community similarity index of the five stations reached ≥ 50%, except for stations III and V (44%). Seemingly that the macrozoobenthos community in the waters of the Ogan River around Baturaja City was relatively the same. Therefore, the community structure of the Ogan River around Baturaja City was relatively stable.

Abstract

Submergence stress and drought stress are main abiotic constraints encountered in South Sumatra swampland rice cultivation area. The development of new abiotic stress tolerant varieties through the introgresion of tolerance genes, such as the Sub1 gene (submergence tolerance) by using Marker-assisted Backcrossing (MABC method) is one of an ideal solution to obtain an adaptive rice variety for those conditions. The study was carried out at Faculty of Agriculture, Sriwijaya University, Indonesia. In this study, BC2F1 used as the plant materials derived from backcross performed in BC1F1 and the recipient parent, Inpago 5. Previously, BC1F1 obtained from backcrossed progenies from Inpara 8 (inherited Sub1A gene) and Inpago 5 as recipient parent, a drought tolerant variety. The main objective of this study was to analyze the Sub1 introgressed plants in backcrossed progeny BC2F1 that closest similarity to recipient parent. The result showed that Sub1 introgression was confirmed by a tightly linked Sub1 gene marker, SUB1C173 marker. Out of 47 plants, 20 plants were selected based on foreground selection. Those plants were further analyzed on background selection by using 13 SSR markers. Based on the foreground and background selection, two plants, viz, plant no. 41 and 44, were selected and will be used for further study.

Abstract

The agricultural sector, especially in Indonesia, is always faced with problems from various factors that can reduce the productivity of a plant. One of these factors is the presence of attacks from plant-disturbing organisms. The method used in this research is by using a purposive sampling method. Samples of diseased plants were observed and taken for observation in the Phytopathology Laboratory, Plant Protection Study Program, Faculty of Agriculture, Sriwijaya University. From the observations that have been made, it was found that many chili plants were attacked by Colletotrichum Rot disease Erwinia caratovora in carrots, anthracnose in oranges and bananas, anthracnose in mangoes, and papayas. Many postharvest diseases found in plants in Indralaya are caused by pathogens in the form of fungi and bacteria.

Abstract

Mangrove is a species of high-level plant whose growth is influenced by the tides of seawater. Antifouling is a system used to prevent marine life attached to an object that is submerged in seawater. The use of natural Antifouling is one of the efforts to reduce water and environmental pollution, such as natural Antifouling from the mangrove plants Rhizophora apiculata and Avicennia alba. The study was conducted in Sungsang, South Sumatera, Indonesia. Avicennia marina and Rhizophora apiculata are mangrove plants that are suspected to have Antifouling content, namely tannins, terpenoids, and steroids. This research aims to determine the effect of the addition of the Avicennia marina fraction and the Rhizophora apiculata fraction on oil paints on the area of macrofouling pasting on the test plate, how the effect of adding different Avicennia marina fractions on the sticking of macrofouling on the wood plate. Avicennia marina and Rhizophora apiculata contain secondary metabolite compounds as natural Antifouling that do not pollute the environment and meet the H0 hypothesis rejected and H1 accepted and suspected that there is no macrofouling on the plates that have been tested proven to reduce pasting.

Abstract

Allantoin is a compound contained in comfrey leaves. This research aims to obtain optimal condition parameters of ionic liquid-ultrasound-assisted extraction (IL-UAE) comfrey leaves to attract allantoin compounds. Comfrey leaves are extracted with eight ionic liquids by ultrasound-assisted extraction (UAE) and screened for allantoin levels. The best ionic liquid from the screening results is optimized response surface methodology (RSM) with Box-Behnken design with three factors and three levels to determine the optimum extraction conditions for allantoin levels. Determination of levels is carried out with TLC densitometry. The results of the IL screening obtained [HMIM]Cl as the best  IL in the evaluation of optimization of extraction parameters. The results of optimization of extraction condition parameters [HMIM]Cl obtained the highest allantoin levels on the sixth run of 306.396 μg / g of powder at the ratio of solvents to powders of 10 mL / g, concentrations [HMIM] Cl 1 mol / L and extraction time of 30 minutes.

Abstract

Lansium domesticum is one of tropical plant. Genetic studies of tropical plant species occurred very slowly due to some obstacles. Provided fresh sample for isolation step was one of impediment. Fresh sample was important conditions to avoid impure DNA template. A simple and rapid technique was needed to get a pure DNA from storage sample. The aims of this study is to see the purity of the DNA isolation results from Lansium domesti-cum mature leaf from South Sumatra that have been stored for 2 years and to test whether the DNA isolation results can be used for barcoding analysis by amplification using PCR method with rbcL primer. There are 11 sample of Lansium domesticum were taken from 8 districts in South Sumatra. The sample was the mature leaves of Lanisum domesticum. The leaves were stored in a freezer at -20oC for two years. There was one sam-ple stored within 2 weeks as a comparison. The results of the study showed the isolation of DNA from storage and mature leaves of Lansium domesticum used Plant Genomic DNA Kit DP305 had a good quantity for 7 sample. 3 sample had low purity and 1 sample contaminated by RNA.  Despite electrophoresis showed the isola-tion result not intact and compact, nevertheless the PCR results showed 11 samples could be amplified using rbcL primer. This result indicated the DNA isolation method suit for barcoding analysis using PCR method.

Abstract

Indonesia is one of the world's largest coal-producing countries. Most coal mining activities are conducted using the open-pit method. A classic problem caused by mining activities is acid mine drainage (AMD). Various conventional methods have been developed to increase the pH of the water and remove heavy metals such as iron (Fe) and manganese (Mn) in acid mine drainage, including chemical precipitation, coagulation, flocculation, microorganisms, adsorption, and passive treatment methods. In this study, a passive treatment method using constructed wetlands with phytoremediation techniques using L. articulate plants was employed. This study aims to analyze the effectiveness of the L. articulate plant in increasing the acidity of water and reducing the levels of Fe and Mn metals dissolved in acid mine drainage. The results of the initial sample analysis of acid mine drainage showed a pH of 2.8. The initial values of Fe met-al concentrations were 0.09 mg/L and Mn 8.10 mg/L. After the phytoremediation process, it was found that L. articulate plants were effective in increasing the pH value and reducing the concentrations of dissolved Fe and Mn metals in acid mine drainage within 20 days. The percentage reduction was 93.33% in the organic reactor and 55.56% in the inorganic reactor for Fe metal concentrations. For Mn metal reduction, the percentages were 38.02% in the organic reactor and 25.80% in the inorganic reactor.

Abstract

The cultivation of pepper plants is usually carried out on dry land, but at this time there is a lot of conversion of pepper plantations to other plantations and even housing. This study aimed to investigate the growth ratio of floating agricultural pepper and dry land, study the best Mg dosage for the growth of pepper with float-ing and dry land systems, andinvestigate the planting system on soil moisture content, pH and Mg content of soil and plants. The research was carried out from September 2020 to January 2021 in the gardens of the Soil Department, Faculty of Agriculture, Sriwijaya University, Indralaya. This research was conducted using the Split Plot Design method with 2 factors. As the main plot is the farming system, namely: S1 = Floating. S2 = On dry land (conventional). Subplots were Mg fertilizer with doses per polybag: Mg0 = No Mg fertilizer, Mg1 = 4g plant-1 , Mg2 = 8 g plant-1 , Mg3 = 12 g plant-1 , Mg4 = 16 g plant-1 . Observations were made on the increase in plant height, number of leaves, elemental content mg, soil water content, soil pH. The results showed that the planting system had an effect on plant height, number of leaves in the 11th week and root length, Mg doses did not affect the growth of pepper and soil. The soil water content of the floating system is higher than the conventional system, whereas the pH is higher in the conventional system than the floating system.
