Abstract
Wilt disease caused by Fusarium oxysporum is one of the major diseases that cause yield loss on shallot plants. An environmentally save control method can be carried out by using biological agents. The antagonistic microorganism that has the potency to control wilt disease is Trichoderma harzianum. A carrier will be needed in a formulation of this antagonistic fungus. The formulation can also be enriched with plant micronutrient. Carbon was proven useful as a carrier of some antagonistic bacteria. Addition of silica nano particles (silica NPs.) in the formulation did not reduce the vialbility of the same antagonistic bacteria. An experiment was carried out to determine the ability of T. harzianum in the formulation with carbon fiber and silica NPs. to suppress the in-vitro growth of F. oxysporum. The experiment was arranged in the completely randomized design with 5 treatments and 5 replications. The treatments were challenging F. oxysporum by T. harzianum in different formulation on potato dextrose agar. The formulation consisted of T. harzianum + 0.5% silica NPs., T. harzianum + 1% silica NPs., T. harzianum + 0.5% silica NPs. + 5% carbon fiber, T. harzianum + 1% silica NPs. + 5% carbon fiber, and T. harzianum only. The results showed that each treatment with T. harzianum in the formulation of carbon fiber + various concentrations of silica NPs. was able to suppress the in vitro growth of F. oxysporum.

Abstract
Date palm cultivation can be done generatively and vegetatively. Tissue culture is one of the techniques used for vegetative date palm cultivation. The weakness of this technique is the presence of genetic variations in the results of propagation through tissue culture known as somaclonal variation. One type of molecular markers commonly used for variations in genetic variation is RAPD (Random Polymorphic Amplified DNA) markers. The aim of the research was to analyze genetic variation of Date Palm genotypes using three RAPD primers - OPD-13, OPD-20, and OPO-16. This research is conducted by taking 8 genotypes from tissue cultur propagation and 2 genotypes from seed propagation. Calculation of distance matrix or genetic inequality is done by two types of descriptive analysis of diversity such as Principal Coordinates Analysis (PcoA) and Neighbor-Joining Tree (NJtree) using DARwin 6.0 software. Based on the cluster analysis, 10 samples of date palm group into three major groups with a total of molecular diversity was 83.11%, The range of dissimilarity coefficient was 0 – 0.6.

Abstract
Vanda tricolor orchids are endemic to the slopes of Mount Merapi, Yogyakarta Province, Indonesia. The mountain slopes and eruptions in 2006 have destroyed 80% of the habitat and threatened the existence of these orchids. In addition, the exploitation of Vanda tricolor out of its natural habitat by the community for collection or selling it outside the area has reduced the orchid population. Therefore, efforts should be carried out to improve technology to reproduce and regenerate Vanda tricolor orchids. One of alternative to regenerate Vanda tricolor is using multiplication technique through in vitro and ex vitro cultures. The objective of this study was to determine the best type and concentration of cytokinin for the multiplication of Vanda tricolor PLBs. The experiment was arranged in a completely randomized design with single factor consist of 7 treatments id est medium without cytokinin, BAP 0.5 mgL-1, BAP 1 mgL-1, TDZ 0.5 mgL-1, TDZ 1 mgL-1, Kinetin 0.5 mgL-1 and Kinetin 1 mgL-1. Parameters observed in this study were a percentage of live, browning and contamination explant, the diameter of PLB, the emergence of shoots, the percentage of explant sprouting, the number of buds, the emergence of roots. The data were analyzed by using The Analysis of Variance at α=5% and further tested using Duncan Multiple Range Test (DMRT) at α=5%. The results showed that BAP 0.5 mg / L was the best cytokinin for multiplication of Vanda tricolor PLBs.

Abstract
Cassava is one of the main crops developed in the Gunung Kidul used as local staple food. There are various varieties cultivated, but its characteristic remains unknown. This information are required to be investigated further as the characteristics of each variety, particularly the nutrient content and physical properties would determine the success of Mocaf (Modified cassava flour) production. This study was conducted using Completely Randomized Design (CRD) consisting of 5 varieties tested, namely Kirik, Gambyong, Jawa, Gatotkaca, and Bamban. Tuber harvested from a 9-months-aged cassava plant were measured for various nutrient contents (protein, ash, starch, fiber, fat, carbohydrate, HCN) and physical properties (tuber color, organoleptic, viscosity, and moisture content). The physical properties and nutrient contents contained in the tuber were varied among varieties. Variety exhibiting the best quality and characteristic among all tested varieties for mocaf production was Bamban. The tuber of this variety had white color (91.53) and contained 18.10 ppm HCN, 77.84% starch, 1.11% protein, and 9.04% dietary fiber. However, these characteristics still had not yet met the national standards of Indonesia, particularly regarding its HCN and starch contents.

Abstract
Synchytrium pogostemonis is one of the most important fungal pathogens. This fungus causes budok disease on patchouli plant. Research to control the disease was conducted at Indonesian Spices and Medicinal Crop Research Institute (ISMCRI) Bogor. Research purpose was to evaluate effectiveness of citronella, clove, and neem essential oil formulas on budok disease incidence. Single formula of citronella, clove, and neem were tested, as well as, their combination formulas of those three essential oils. Two synthetic fungicides (benomyl and bourdeaux mixture) were also tested as comparisons, as well as, water as a control treatment. One-month-old patchouli plants were sprayed with single and combination formulas of those three essential oils (5 ml/l), benomyl (3 g/l), bourdeaux mixture (1 g/l) and water as much as (100-200 ml/plant) every two weeks for 5 times respectively. Experiment was conducted in a Randomized Completelly Block Designed (10 treatments, 3 replicates, and 16 plants/replicate). This experiment indicated that application of combination formula of (neem+citronella) was the most effective (56.51%) against budok disease. Its effectiveness was higher and comparable to benomyl (47.82%) and bourdeaux mixture (52.18%). This combination formula of (citronella+neem) could be recommended for the control of budok disease of patchouli. The use of essential oils combination formulas, hopefully could control budok disease, inhibit the resistancy of target pathogens, reduce the concentration of the more toxic essential oil once, reduce phytotoxicity, as well as, to reduce the use of synthetic pesticides.

Abstract
Goosegrass (Eleusine indica) is an important weed in rubber plantation. It is getting more difficult to control with glyphosate herbicide of which is normally very common used to control the weed in rubber plantation in North Sumatra. The objective of the study was to evaluate the efficacy of preemergent (indaziflam 150g a.i/ha) and postemergent herbicides (glyphosate 720g a.e./ha, paraquat 400g a.i/ha, ammonium glufosinate 450g a.i./ha) alone or mixtures (glyphosate 720g a.i + metsulfuron methyl 15g a.i./ha, glyphosate 720g a.e./ha + 100g indaziflam a.i/ha) on goosegrass growing on the rubber field along the rubber row. Apart from those treatments there were plots cleared by scrapping the soil surface and plot without treatment. The results showed that indaziflam at 150g/ha and 720 g a.e glyphosate /ha + 100g indaziflam/ha) and manually only cleared controlled the goosegrass effectively followed by 450 g a.i ammonium glufosinate /ha whereas paraquat at 400g.a.i/ha and glyphosate at 720 g a.e/ha either alone or mixture with metsulfuron methyl at 15 g a.i/ha did not control goosegrass satisfactorily

Abstract
Waste of soybean husk seeds (SHS) is very potential organic waste to be used as organic fertilizer through vermicomposting techniques. To find out the potential, it is necessary to characterize the vermicompost metabolites produced, because by detecting metabolites it will be useful in studying the profile and its metabolic pathway. Gas Chromatography-Mass Spectroscopy (GC-MS) is used to detect metabolites because it is a powerful tool in characterizing vermicompost. The purpose of this study is to detect vermicompost metabolites made from raw materials of SHS waste and combination with cow manure. Thus, further information obtained can be used as a recommendation in handling SHS waste specifically as organic fertilizer through vermicomposting techniques. The study of vermicomposting was conducted using Randomized Block Design (RBD) with 5 treatments and 5 repetition. The treatment details are: V1: SHS waste (100%), V2: cow manure (100%), V3: SHS waste: cow manure (50%: 50%), V4: SHS waste: cow manure (75 %: 25%) and V5: SHS waste: cow manure (25%: 75%). Data were analyzed using GC-MS and Honestly Significant Difference (HSD) test. Based on the analysis using GC-MS in all treatments (V1-V5), there were detected metabolites classified as primary metabolites, consisting of: seven sugar compounds, 20 amino acid compounds, nine vitamins, three hormones and 43 organic acids. The treatment showed an increase in the chromatogram start of treatment V1-V5, and this result is directly proportional to HSD test where V5 treatment also showed the highest total curve.

Abstract
Selection is the activity of selecting individuals the best plants based on the desired character. Selection will be effective if the right selection character is used. The aims of this study to determine agronomic characters that can be used as character selection in the cross-bred potato line population through heritability, genetic diversity, genotypic correlation, and selection of these lines. The experiment was conducted at the Green House, Sumber Brantas Village, Batu City, East Java. The materials used were 30 lines of potatoes as a result of the LJPRSD1 x AP-4 varieties crossing. The experimental design used in this study was a completely randomized design (CRD) with 3 replications. Observed agronomic characters were plant height, stem diameter, number of leaves, tuber diameter, number of bulbs, length of bulbs, weight per-bulb, starch content, and glucose. The result of heritability in almost all characters had a high value, except for the character of stem diameter and tuber length. Genotypic diversity in the character of stem diameter, bulb diameter, bulb length are low, while other characters are rather-low. Significant genotypic correlations between characters, except starch-content, to the weight per-bulb character. Agronomic characters that can be used as character selection are plant height, tuber diameter, and number of tubers.

Abstract
Indonesia is one of the megabiodiversity countries, but only about 25% of its biodiversity has been cultivated, and some of them are rare and endangered. One of the rare plants that is very useful and has the potential to be developed is kepel (Stelechocarpus burahol (Bl.) Hook. F. & Thomson). Kepel or Burahol is an identity plant of Yogyakarta Province, known as a palace plant and often used as natural perfume and biopharma. This research was conducted to obtain a map of kepel distribution and to identify the morphological characterization of kepel plants in the Yogyakarta Palace and its surroundings. The study was conducted using a survey method with the purpose of sampling in the Yogyakarta Palace and its surrounding area. The sample plants were kepel plants that have been fruitful. Each plant was observed, and the morphological parameters measured included stem, leaf, and canopy. Observation variables according to the description for Annonaceae plants were based on Bioversity International, International Plant Genetic Resources Institute (IPGRI) in 2008. Data from observations were presented in the form of scoring, then analyzed to assess the similarity matrix using SIMQUAL (Similarity for Qualitative Data) procedures. Grouping of matrix data (cluster analysis) and making dendograms was done by the Unweigthed Pair-Group Method Arithmetic Average (UPGMA) method using numerical Taxonomic and Multivariate System (NTSYS) version 2.02i. The results showed that based on the map of kepel plant distribution in the Yogyakarta Palace and its surrounding, the diversity of vegetative character of plants was random, and there was no grouping for certain accessions. Based on the morphological characterization of kepel plants in the Yogyakarta Palace and its surrounding showed uniformity in the canopy shape and leaf edge shape, however, it had diversity in leaf shape, leaf base, leaf tip, leaf color, leaf length, leaf width, leaf stalk length, color stem and a number of branches. Based on the similarity of morphological characterization (canopy, stem, and leaf ), kepel plants in the Yogyakarta Palace and its surrounding can be grouped into three clusters with a similarity level of 0.5. Cluster A consists of 17 accessions, Cluster B consists of 23 accessions, while cluster C consists of 6 accessions. The diversity of morphological characterization of kepel in in the Yogyakarta Palace and its surrounding can be used for plant selection to improve traits.

Abstract
Mosaic disease on patchouli has developed very rapidly, in a period of 3 years it has spread to patchouli cultivation centers in Sumatra, Java, and Sulawesi. Therefore, prevention of the spread and control of this disease is a major concern. Volatile oil and plant extracts contain active substances that can inhibit viral infections in plant tissues. The highest percentage of mosaic virus inhibition originating from patchouli plant in Chenopodium amaranticolor test by nanoemulsion formula citronella dose 1% (74.87%) and clove dose 0.5% (43.55%). Citronella nano pesticide fragrant dose of 1% with the application time every month effectively suppresses the development of mosaic disease in patchouli plants of Sidikalang variety in Bandung-West Java and Banten. This study aims to look at the effectiveness of the clove nano biopesticide formula against patchouli mosaic virus and its economic feasibility study. The study was conducted at the Manoko Experimental Garden, Bandung, West Java from March to November 2018. This study was compiled with Randomized Block Design (RBD) with 5 treatments of 10 replications and each replication of 100 plants. The results obtained showed that the efficacy of citronella, clove, and commercial citronella (Asimbo) nano biopesticide formulas on the intensity of mosaic disease compared to without treatment were 14.68%, 9.06%, and 5.83%, respectively. While the intensity of attack of patchouli leaf rollers were 38.03%, 35.21%, and 0% respectively. The efficacy of chemical insecticides on aphids attack was 32.39%, not different from the administration of the biopesticide nano formula citronella and clove. The yield loss of patchoulina 2 varieties compare with control without treatment ranged from 5.14 to 14.96%. Levels of patchouli alcohol> 30% (meet SNI standard of quality) but oil yield <1. Nano Biopesticides cloves have the potential as biopesticides to control plant viruses.

Abstract
Whitefly, Bemisia tabaci, is a polyfag insect and one of the important pests in vegetable plants at Indonesia. Loss of yield due to whitefly attack on host plants is 20% -100%. Chemical control with pesticides is less effective because the whitefly body is covered by a layer of wax. Whitefly control with resistant or tolerant plants is needed. Whitefly is a sap-sucking leaf plant insect. Therefore plant vegetables breeding for resistance varieties or tolerance refers to the leaf morphology as physical barrier such as number of trichome, slope of trichome, density and length of palisade tissue, cuticula layer and leaf thickness. The aim of this study was to review the effects of leaf morphology of the Bemisia tabaci Genn. on Brassicaceae, Cucurbitaceae, Fabaceae, Malvaceae and Solanaceae. With this summarize character target of plant vegetables breeding will become more clearer to be achieved.

Abstract
Community income of West Java coastal areas ranging from Pelabuhan Ratu area to the coastal area of Leuweung Sancang in South Garut, West Java is fishing. Their daily life is very dependent on the results of fishing in the sea. Livelihoods like this are highly dependent on the condition of the seasons. This makes the life of coastal communities are often categorized as food insecure communities. The longer dry season than the rainy season adds to the livelihood of the community tends to suffer from food insecurity. Jalawure (Tacca leontopetaloides) is one of the plant species that grows on the coast, has tubers containing a high source of carbohydrates and mineral content which can be utilized by the community to overcome such dry conditions. This research was conducted from 2016-2018 in several villages, namely the coast of Kerta Jaya Village (Sukabumi Regency), Cidamar (Cianjur Selatan, Cianjur Regency), Mancagahar, Pameungpeuk, Leuweung Sancang (Garut Regency), West Java. Ethnobotany study of jalawure is discussed in this manuscript.

Abstract
Rapid postharvest deterioration of cassava (Manihot esculenta Crantz) root also known as postharvest physiological deterioration (PPD) is a major problem to the utilisation and development of cassava as a food and commercial commodity. De-glucosylation of scopolin regulates the homeostasis of scopoletin in the cells by the action of scopolin-beta-glucosidase (scopolin-BG). This enzyme releases scopoletin, a major component that plays a central role in cassava root deterioration, under stress conditions. However, an understanding of how this pathway contributes to root deterioration development and the specific genes for this enzyme in cassava remains undefined. We first investigated the diversity of scopolin-BG in cassava and manipulated the de-glucosylation of scopolin pathway via over-expression of a scopolin-BG gene, BGLU23, from Arabidopsis. We found that cassava scopolin-BG is encoded by multiple genes, most of which belong to glycosyl hydrolase family-1 (GH1). Identified homologous cassava scopolin-BG genes shared low amino acid sequence similarity with the reference gene, BGLU23, between 34 and 46%, and the phylogenetic tree revealed that none of them were closely related to BGLU23. Scopoletin and scopolin were detected at low levels in fresh roots of transgenic cassava, but their accumulation was significantly increased at day 2, accompanied by the up-regulation of BGLU23. Although it appears that de-glucosylation of scopolin does not play a crucial role in the accumulation of scopoletin in cassava, some BLU23-expressing transgenic cassava showed significantly delayed PPD compared to wild type control. This study has improved our understanding of biochemical pathway involved in PPD and provided alternative way to tackle this problem.
