Abstract

ABSTRACT Vesicular Arbuscular Mycorrhizae (VAM) Identification of Red Onion (Allium cepa L.) and Taro (Colocasean esculenta (L.)Schott) Rhizosphere and Its Spore Multiplication in Zeolite Media Efforts to increase agricultural production can be done with a variety of technologies. Technology is widely applied to farmers in the cultivation process is the use of inorganic fertilizers with high doses exceeding the dose of balanced fertilizer. In the production of onion crops in the field, also using inorganic fertilizer application on an ongoing basis which may result in damage to the ground both in terms of texture and structure. Red onions and taro roots are shallow causing both of these plants are unable to absorb nutrients to the maximum if exercised enough chemical fertilizer. This study was aimed to determine genus and species of VAM in red onion and taro rhizosphere, its colonization in root tissue, and to examine zeolite media compatibility with corn as a symbiont. Based on the results of the study, it was found three species of VAM spores of red red onion plant rhizosphere, namely: Acaulospora denticulata, A. laevis, Glomus ambisporum, and five species of VAM spores recovered from the rhizosphere of taro plants namely: Acaulospora foveata, A. koskei, A. capsicula, Scutellospora calospora and Glomus ambisporum. Infections were found in plants onion, taro and corn plants form symbiotic arbuscular, vesicles and inner spore. VAM from the rhizosphere of plants onion and taro can be reproduced using zeolite media and symbionts plant corn. Keywords: MVA, rhizosphere, Acaulospora, zeolite, inner spore

Abstract

The Effectiveness Test of Extracts Of Betel Leaf (Piper Betle L.), Kirinyuh (Chromoloena Odorata) and Tembelekan (Lantana Camara L.) Against The Population of Root Knot Nematodes (Meloidogyne Spp.) and Plant Growth of Chili (Capsicum Annuum L.)Meloidogyne spp. was one of the parasitic nematode pests on crops of chili. Meloidogyne spp. was widespread in tropical regions and subtropik area.. Attacks of Meloidogyne spp. at the root can lower the production of the crops by 15 – 60 percent, even can reach 70 percent when the disease attacks vulnerable plants (Prihanto,1989). This research was carried out in a way controlling root knot nematodes on chili uses extract of 3 species of plants in a variety of concentrations with the aim to obtain a concentration from the plants that are very effective at suppressing the development of root knot nematodes and can suppress the population in the soil and as well to surpress the attacks on plant roots.The types of plants that will be used in this research is kirinyuh (Chromolaena odorata), tembelekan (Lantana camara) and betel leaf (Piper betle) in different concentrations to know their ability to suppress populations of root knot nematodes of chili. The leaves of the plant contains useful materials to suppress plant pests including root knot nematodes. From the three of leaf extract that have been used, the betel leaf extract effectively suppress the populations of nematodes on crops of chili for being able to put pressure against the population of the nematode in the soil or plant roots of chili. At the concentrations of 50 cc/polybag betel extracts are able to suppress the nematode population to 93% and on the concentration of 200cc/ polybag betel extracts was able to suppress populations of nematodes were 96.4%.

Abstract

Exploration of Cellulolytic Bacteria from Organic Waste in DenpasarMunicipal waste is one of the problem that must be overcome in Denpasar City. Municipal waste volume of Denpasar City 2014 was 1,247,769 m3, Year 2015 was 1,294,696 m3, and 2016 was increased to 1,296,438 m3. Total of waste that produced by Denpasar City is 70% organic waste. This type of organic waste has a major component of lignocellulose consisting of three polymers namely, cellulose, hemicellulose, and lignin. Cellulose is a component of plant cell walls. Cellulose has a low digestibility so it takes a long time to be degraded. One of the microorganisms that can produce the enzyme is the cellulolytic bacteria. The purpose of this research was to find and identify isolate of cellulolytic bacteria isolated from organic waste of Denpasar City. This research was conducted from September to 2017 until March 2018. Organic municipal waste samples were taken from each District in Denpasar City each one sample. Bacteria from the organic waste was isolated dan identified by moleculer identification in order to know the cellulolytic bacteria spesies. Based on the result of the research, two isolates of bacteria with the highest cellulolytic indeks were B-6 and U-6 isolates that were 7.3 and 3,0. The formation of clear zones around the colony showed that the isolates had qualitatively measured cellulolytic activity. The identification of both isolates was found were the B-6 isolate had the same percentage as Lactobacillus acidophilus (95%) and U-6 isolate had similarity percentage with Enterobacter cloacae (94%).

Abstract

Transmission of Symptomatic Mosaic Virus in Melon (Cucumis melo L.)Mechanically and Through the Aphids Vector Melon (Cucumis melo L.) is one of the horticulture plants that is widely cultivated and consumed by the people of Indonesia. But the decrease in yield due toan OPT attack (plant disrupting organisms) is a major concern. Among the pests thatplay a role in reducing the yield of melons are viruses and insect vectors. Aside frombeing a pest, aphid insect also act as vector transmitters of viruses that cause mosaicsin melon plants. The method of transmission in this research used the method oftransmission mechanically and through aphids vectors. The aim of this research wasto examine the potential transmission of Potyvirus wich caused mosaic on melonmechanically and through the vector Aphis gossypii. The parameters are the type ofsymptoms, the percentage of the disease and the intensity of the disease attack. Thevariations of symptoms showen were dark green mosaic patterns, yellow mosaicpatterns, vein-banding and malformations. The results of the transmission test wereproven by molecular identification using the Reverse Transcription Polymerase ChainReaction method. The results explained that the Potyvirus could be transmittedmechanically with disease incidence of 100%, disease intensity of 42% and throughAphis gossypii vector with a disease incidence of 90%, disease intensity of 28%. Thetest was proven using the RT-PCR method with CIFor and CIRev primers whichshowed amplicon product 700 pb.

Abstract

ABSTRACT Identification of the Ginger Plant (Familiy of Zingiberaceae) in Bali, as an Element in Landscape Design Ginger plants (Family Zingiberaceae) wellgrow in most regions in Indonesia, including Bali. Beside as a medicinal plants, the plant is also currently used as an element in design of landscape. Objectives of the research were: 1) inventory and identify plants of Zingiberaceae family found in bali; 2) to group those plant in to the specific element of landscape design according to their heght, color and texture; 3) to find out the level of preferences of people to those plant. Method use in reseach were a survey method and organoleptic test. Data were collected from eight regencies and one city in Bali throught a survey. Organoleptic test was done 30 respondents, including 10 peoples who expert in landscape design. The result of the survey investigated 35 speciments of grown in Bali. Those spesiments were identified and grouped in to 9 genera, i. e. Alpinia, Amomum, Boesenbergia, Curcuma, Eletaria, Etlingera, Hedychium, Kaempferia, and Zingiber. Regarding, to group in to specific element of landscape design, plant are grouped into: size (6 tall shrubs, 18 medium shrubs, 8 low shrubs and 1 ground cover), colour (21 flower, 8 leaf varian color) and texture (8 coarse, 19 medium and 5 smooth). Organoleptik test showed that flowers that have bright colour and varied in shape were the most favoured by respondents. However, species of Kaempferia galanga had highest level of preference by respondents on the shape and colour of plant in a whole. While, leaf that have combination of the colour and taper leaf shape were the most favoured by respondents. Keyword : identification, Zingiberaceae, landscape design

Abstract

The effect of using various packaging treatments on extend the shelf life of strawberry fruit and their physico-chemical changes Strawberry is one among horticultural commodities that has a significant potential being developed commercially in Bali. Strawberry fruit commonly has a relatively sweet taste and a strikingly bright red color. Strawberry fruit is easily damaged and has a short shelf life, so it is necessary to inhibit the damage, among others by the use of various packaging treatments. This study aims to extend the shelf life of strawberry fruit and the effect of using various packaging treatments on their physico-chemical changes. The experimental design used was completely randomized design with one packing type factor consisting of 3 treatment levels, ie without packaging, use of mica package, and use of styrofoam package.The results showed that strawberry fruits treated with mica and styrofoam pacgages had a longer shelf life than strawberry fruit stored without any packaging (control). The storage period of strawberries both treated with mica and styrofoam packeges were last up to the 4th day. The use of mica package showed the best results with the lowest shrinkage value, lowest softness, low respiration rate and high organoleptic value. Eventhough strawberry fruit packed with styrofoam package showed a high vitamin C content, but the strawberry fruit packed with mica package has a better visual appearance with good fruit quality and mostly accepted by the panelist.

Abstract

The effect ot the type of herbicide to controlling weeds and the increasing thegrowth and yield of rice plants in tabelaltot planting system. Rice plants are the most important crop cultivation because most of the population makes rice as a staple food. Efforts to support the fulfillment of rice needsare made by maintaining rice productivity. Increased rice productivity is currently stillexperiencing obstacles such as in improper crop cultivation techniques and problemsin weed control, therefore proper weed cultivation and control techniques need to beassessed. The purpose of this research was to find out the type of herbicide that is mosteffective in controlling weeds and can increase the growth and yield of rice plants intabelaltot planting system. This study used a randomized block design (RCBD) with4 treatments, namely control (without herbicide treatment), logran herbicide,metafuron herbicide and benfuron herbicide. The treatment was repeated six times.The results showed that the herbicide treatment significantly affected the weight of thedried grain harvest compared with control. Logran herbicide treatment showed thehighest dry grain weight of ha-1 harvest was 8.38 tons / ha-1 and significantly differentfrom the control of 6.00 tons / ha-1, the high yield was due to the ability of logranherbicide that could suppress growth of the highest weeds, namely 77% compared toherbicides metafuron namely 57% and benfuron namely 56% and significantlydifferent compared to controls, the competition that occurred between rice plants andweeds in logran herbicide treatment was less so that it made yields increase.
