Can Oecophylla smaragdina be used to suppress incidence of CVPD in citrus orchards in Indonesia? G Andrew C Beattie * and Paul Holford
School of Science, Western Sydney University, Locked Bag 1797, Penrith, NSW 2751, Australia
Abstract
Citrus vein phloem degeneration (kerusakan pembuluh tapis pada jeruk) is the Indonesian name for the Asian form of the devastating and incurable citrus disease known internationally as huanglongbing. It is associated with a phloem-limited pathogen, Candidatus Liberibacter asiaticus (CLas) and transmitted by the Asiatic citrus psyllid (ACP), Diaphorina citri. ACP originated in South Asia but was first observed on citrus in 1900 in Java to where it may have been introduced decades earlier on lemon or lime seedlings brought from South Asia to reduce the incidence of scurvy among European sailors and in colonial settlements. CLas appears to have been introduced to the Pasar Minggu area of Jakarta in the 1940s from southern China, after it was introduced to Guangzhou, directly or indirectly, from South Asia in the late 1920s-early 1930s. Minimising incidence of the disease relies on planting pathogen-free trees, removal of infected trees, and unstainable use of synthetic pesticides that do not prevent spread of the disease. Parasitoids and predators of ACP are killed by the pesticides. Evidence from China and Vietnam suggests that effective management of the disease may be feasible if the weaver ant (semut rangrang), Oecophylla smaragdina, is deployed, cultivated, and managed in orchards.

Abstract
Soybean consumption (Glycine max L.) in Indonesia has increased significantly. The very large demand for soybeans and limited ability to import demand the immediate development of domestic soybeans. One of the inhibitors that can reduce soybean production is a disease caused by the fungus Athelia rolfsii (Curzi). The development program needs to be supported by plant breeding as an effort to overcome problems in developing soybean cultivation technology, one of which is by assembling high-yielding varieties that are always accompanied by disease-resistant characters. This study was aimed to determine the level of resistance to stem rot disease of A. rolfsii Curzi and production of soybean (M7) mutan genotype under disease stress and optimum condition. This research was conducted in 2019 using an augmented design. The treatments used were 11 mutant genotypes and 3 comparison varieties, anjasmoro variety, argomulyo variety, and kipas putih variety. The results showed that genetic diversity and heritability between genotypes of the M7 generation had high values for each production character except for the characters of flowering age, number of productive branches and weight of 100 seeds. The appearance of agronomic characters observed in agronomic traits on inoculated area by A. rolfsii Curzi that caused stem rot disease is lower than the optimum field. Based on the plant sensitivity index, genotype M100A25 (3/7) and M200A12(6/5) had resistant to stem rot disease while M100A25(5/3), M100A25(3/4), M100A6(31/1), M200A11(32/3) had moderate resistance to stem rot disease. The result of strains selection on M7 generation resulted in two strain with high production character and resistance to stem rot disease, M100A25 (3/7) and M200A12(6/5).

Abstract
This study aims to determine the pattern of planting points, and to determine the effect of weed control with pre-emergence herbicides on the growth and production of maize. This research was conducted from November 2019 to the end of February 2020 in Sendang Rejo Village, Binjai District, Langkat Regency. The design of this study used factorial split-plot design: Factor I: The planting point pattern (P)- P1 = Single row cropping point pattern (70 cm x 20 cm), P2 = Two row planting point pattern (20 cm x 20 cm, the next row spacing is 70 cm), P3 = Triangular planting point pattern (20 cm x 20 cm, distance with the next row of triangles 70 cm). Factor II: Herbicide Application (H)- H1 = No herbicide application (control), H2 = Weed free (manual control), H3 = applied with dimethenamide-P + saflufenacil 3 days before planting, H4 = applied with dimethenamide-P + saflufenacil at planting, H5 = applied with dimethenamide-P + saflufenacil aged 3 DAP H6 = applied with topramezone + atrazine at 14 DAP, H7 = applied with topramezone + atrazine at 21 DAP. Parameters observed in this study were plant height, amount of leaf chlorophyll and production. The results showed that the pattern of planting points had a very significant effect on plant height at the age of 6 and 8 WAP and total chlorophyll and corn production (Zea mays L.). Weed control with pre-emergence and post-growth herbicides had no significant effect on plant height, total chlorophyll and maize production (Zea mays L.). However, from this study it was found that the best herbicide application was at H7 (Toppramezone + atrazine at 21 days after planting). While the use of planting point patterns and weed control with pre-emergence and post-growth herbicides interacted significantly with the observation of total chlorophyll, while there was no significant effect on the observation of plant height and maize production (Zea mays L.).

The main production region located at the highland of northern side of Tanggamus namely Sub-district of Air Naningan, Pulau Panggung, and Ulu Belu which bordering with protected forest area. This research was conducted in Sumberejo Sub-district of Tanggamus Regency using survey method and Focused Group Discussion, considering that Sumberejo was the population center and the main coffee producer among Talang Padang ex-subdistrict region. The study involved 3 villages that chosen purposively with 71 respondent of coffee farmers that determined using simple random sampling method, and 3 series of FGD in April 2019 until September 2020. Data was analyzed using both descriptive and quantitative method. The results show that there are 49% sample farmers that grow coffee located at medium (5-19 km) or long distance (≥-20 km) from home. There are 25-76% sample farmers work as seasonal migrant who usually (76.5% farmers) come to the garden once a month or once in two months. About 38% of sample farmers have coffee plantations outside Sumberejo Sub-district mainly at Sub-district of Air Naningan and Ulu Belu. Long-distance coffee plantations are characterized by larger landholdings (1.5 ha on average), higher coffee stands per hectare (2,456 trees on average), and are dominated by mature coffee trees (41% farmers) and younger coffee trees (29% farmers). The more distance from home the lower shade trees population is. However more divers of MPTS are found in coffee plantation that located close to home residency. The yield of coffee plantations that are close or medium distance from home ranges 0.75-0.77 ton per hectare per year. Meanwhile, coffee plantations that are located far distance from home get a yield of 0.94 ton per hectare.

Abstract
Long-term tillage and fertilization system have a strong impact on the abundance and biomass of earthworms in agriculture soils, however, enumerating their influence on mungbean plantation remains little studied. The objective of this study was to determine the effect of long-term tillage and fertilization and their interaction on the abundance and biomass of earthworms under mungbean plantations. Two factors of treatments consisted of tillage system (minimum tillage and intensive tillage) and fertilization (without fertilization and fertilization by NPK (15:15:15) + chicken manure) what has been done since the first (2017) to sixth planting season (2020). The hand sorting method was conducted and observed 3 times throughout the planting of mung beans. The results show that the abundance and biomass of earthworms are significantly higher in minimum tillage compared to intensive tillage as well as fertilization compare to without fertilization. The greatest abundance and biomass of earthworms were found in the maximum vegetative of mungbean. The interaction effect occurred at the maximum vegetative observation, namely in intensive tillage, there was no effect of fertilization, on the contrary, at minimum tillage, fertilization increased the abundance and biomass of earthworms. As a consequence, our results indicate that minimum tillage and fertilization significantly improve soil biological quality.

Abstract
Abstract. Coffee is one of the most potential commodities in the world, being the second most traded commodity. Currently, it is consumed as the second-largest beverage around the world and has become part of the lifestyle of today^s generation. As a result of the increasing number of its utilisation, it generates a considerable amount of waste, the coffee spent grounds (CSG) is one of the instances. In general, the CSG that are produced are only disposed of directly (landfill). On the other hand, CSG still contains carbohydrates, oil, nitrogen and carbon which have the potential to be used to produce several products as a means of valorization, including biodiesel, biopolymers, composites, compost and biochar. The purpose of this study was to systematically review the use of CSG as a feedstock of biochar, conditions of biochar production, its properties and application as an adsorbent of chemicals causing environmental damage. The research method used a systematic review of the selected journals on the topics, then was further analyzed both in the theory and content. The results of the literature review suggest that CSGs have potential use as a feedstock for biochar production and have been researched for an adsorbent on a wide range of pollutants. The CSG biochars are effective adsorbents for cadmium (II), Methylene Blue, Tetracycline, Zn (II) compounds, and ineffective on Sulfamethoxazole compounds.

FP UNS Surakarta
Abstract
The use of biochar can improve the physical, chemical and biological properties of the soil. The application of biochar is expected to further increase the effectiveness of BiO2-biofilm biofertilizer in supporting rice growth so that it can provide higher yields. The purpose of this study was to obtain the optimal formula for the use of biochar and BiO2 for rice yields. The study was conducted in a greenhouse using a pot with a split plot design with three replications. The first factor (main plot) is the concentration of BiO2 (0 and 100 %), the second factor (sub plot) dose of biochar (0- 15 and 30 tons ha-1) and the third factor (sub-plot) method of use (mixed homogeneously to soil and is given at soil surface). The biochar used is sized to pass the 2 mm sieve. Observation variables include plant growth and yield as well as physical, chemical and biological properties of the soil. Statistical analysis using ANOVA followed by Duncan^s multiple range test. The results showed that the use of biochar up to a dose of 30 tons ha-1 in the application of 100% concentration of BiO2 liquid biofertilizer showed an increase in rice growth.

Abstract
The Atmyb61 gene plays an important role in lignin biosynthesis. Lignin is potentially used for renewable chemicals and biomaterials. This study was aimed to modify the lignin content of two rice varieties Nipponbare (ssp Japonica) and Rojolele (ssp Javanica). The AtMyb61 gene under the control of a strong constitutive promoter CaMV 35S was transformed into those rice varieties mediated by the Agrobacterium tumefaciens strain LBA 4404. From this Agrobacterium transformation, a total of 192 putative transgenic plants were obtained, of which 85 and 18 putative transgenic plants for Nipponbare and Rojolele, respectively. The highest regeneration efficiency (57.73%) and transformation efficiency (10.20%) was obtained from rice cv Nipponbare. Meanwhile, regeneration and transformation efficiency of rice cv Rojolele was, consecutively, almost two times (28.93%) and four times (2.25%) lower than that of rice cv Nipponbare. In planta HPT leave assay showed that 85 (68.55%) and 18 (26.47%) plants of rice cv Nipponbare and Rojolele, respectively, expressed hygromycin phosphotransferase indicated that the rice plants positive contained inserted genes. Further evaluation on the expression of rice genes related to lignin biosynthesis, lignin content, and other physiological and agronomical characters will be carried out.

Abstract
Moler caused by Fusarium oxysporum f.sp.cepae is a seed-borne disease, so the disease intensity in the field is depend on the amount of initial inoculum in the infected bulbs as seed. Therefore, the detection of seed-borne pathogens is important to determine the potential of their transmission. The aim of this research was to evaluate the sensitivity of the bulb tissue of shallot based on the pathogen Infection Index by incubation method on agar media. The experiment was conducted using a completely randomized design with five replications and three varieties of shallots (Thailand, Bima, and Bauji). Each treatment unit was placed in a Petri dish with a diameter of 20 cm, containing 40 mL PDA on which 16 pieces of tissue at the tip, middle, and base of the bulb tissues were placed, which were incubated for 7 days. Pathogen Infection Index is a parameter that was observed macroscopically and microscopically. The results showed that the base of the bulbs tissue of the three varieties tested showed higher sensitivity than the other part to detect the presence of F. oxysporum f.sp. cepae in shallot.

COMBINATION OF GENOTYPE, PLANT SPACING, AND PLANT DENSITY FOR IMPROVING GROWTH AND YIELD OF GARLIC NATIONAL VARIETIES Nazly Aswani, Asih K. Karjadi, and Agnofi Merdeka Efendi
INDONESIAN VEGETABLE RESEARCH INSTITUTE (IVEGRI), IAARD
Abstract
Indonesia has been the largest garlic importing country for decades since the productivities and qualities of national garlic varieties failed to meet domestic demand. Breeding garlic for higher yield conventionally is almost impracticable due to its flowering hinderance, meanwhile the biotechnological approach needs longer time to implement the result. Thus, the most feasible improvement might be done through agronomic aspects. This research was aimed to search for alternative ways in cultivation techniques to improve garlic production. The research was conducted from June 2020 until February 2021 on IVEGRI^s Margahayu experimental station, Lembang, West Java. A split-split plot design was laid out for the combination between varieties as the main plot, plant spacing as the subplot, and plant density (number of seed cloves planted on each planting hole) as the sub-sub plot. The results showed that among all characters observed, the significant interactions between these three factors occurred only in the number of stomata, and seed bulb diameter (4 months after harvested). Meanwhile, the significant interactions either between variety and plant spacing or variety and plant density were recorded in the percentage of the 1st week population, fresh weight per sample, weight after curing per sample, dry weight (4 months after harvested) per sample and weight loss per sample. Pseudo stem diameter was significantly affected by the interaction only between variety and plant density, meanwhile bulb diameter after curing was affected by variety and plant spacing separately. However, the height of dried bulb and number of chlorophyll (SPAD) showed highly significant differences only among the varieties.

Effectiveness and Compatibility of Bacillus and Trichoderma in Increasing Disease Tolerance of Garlic to Basal Rot caused by Fusarium oxysporum f.sp. cepae SH Poromarto, Herlina R Putri, S Widono, Supyani, Hadiwiyono
Universitas Sebelas Maret
Abstract
The main obstacle to garlic cultivation is the attack of Fusarium oxypsorum f. sp. cepae (FOCe) causes basal rot. Bacillus and Trichoderma are popular antagonist microorganisms that can act as biological control agents (BCA). This paper would like to report on the effectiveness and compatibility of Bacillus sp. and Trichoderma sp. as a biological control of basal rot of garlic based on laboratory and Greenhouse tests. The results of in vitro studies show that Bacillus and Trichoderma are potential antagonist agents through antibiosis and even Trichoderma through competition. Meanwhile, in vivo, the two biological control agents were not effective in reducing wilting intensity but effective in reducing basal rot intensity and increasing disease tolerance. Increasing disease tolerance is showed by the yield that is higher significantly than those control with no BCA. Bacillus sp. and Trichoderma sp. have been shown to be incompatible BCA based on both in vitro and in vivo tests, which are indicated by the effectiveness of the combination application being less effective than alone.

Abstract
Olfactory therapy with essential oils can improve the ability to smell and become one of the strategies to relieve anosmia. Tuberose essential oil formulated with eucalyptol can be a new strategy for olfactory therapy by exploring new sources of essential oils. The unstable characteristics of essential oils can be improved by nanoencapsulation. This research was conducted by formulating the essential oil of midnight flower with eucalyptol through sensory testing. The nanoencapsulation process was carried out with nanosilica on a magnetic stirrer for 24 hours. The characteristics of essential oil nanoencapsulation were tested by SEM, chemical component analysis by FTIR and GCMS and stability test by evaporation rate test. The 1:2 formulation (tuberculous flower: eucalyptol) was obtained as the best result of the sensory test. The GCMS and FTIR tests confirmed the main components of the tuberose essential oil formulation and eucalyptol, namely 1,8-cineole which was stable after the nanoencapsulation process. The nanoencapsulation process in formulated essential oils is known to have an average shrinkage percentage (6.664%) which is much lower than essential oils without encapsulation (10.145%). Nanoencapsulation increased the stability and activity of the active components of tuberose essential oil and eucalyptol.

Abstract
Pachira is an ornamental plant that can be used as biodiesel, because of the high-fat content in the seeds. Biodiesel is an alternative fuel that can be used to replace fossil fuels. By using biodiesel as a fuel, it will support a sustainable agricultural system that can produce energy for other sectors outside of agriculture. Pachira plant breeding has not been widely carried out in Indonesia, so the potential use of pachira seeds as biodiesel has not been highlighted. This research was conducted to determine the concentration and timing of chitosan administration for pachira breeding. The study was conducted in Blora Regency using a completely randomized block experimental design (RAKL) with two treatment fac-tors, namely concentration and time of administration. The concentration was divided into three levels, namely 1%, 2%, and 4% concentration, the time of administration was divided into three levels, namely in the morning, afternoon, morning, and afternoon. The administration of chitosan was carried out every week as much as 20 ml according to the treatment. Maintenance carried out is to pour 50 ml of water every day on all research samples. The results showed that treatment with a concentration of 4% and watering in the afternoon could stimulate plant height growth at the beginning of the seedling phase, having the most leaves, producing greener leaf colors and having wider roots.

Abstract
Shallot (Allium ascalonicum L.) is a horticultural commodity that has good potential to be developed in Indonesia. To overcome uncertain climatic conditions and demand that continues to increase along with the increase in population in Indonesia, it is necessary to develop technology in shallot cultivation that using NFT hydroponic system. This research was carried out with the aim to determine the interaction between plant spacing and tuber cutting on the growth and yield of shallot. The study used a two-factor split-plot design replicated 3 times. The main plot used plant spacing consisting of 3 levels (10x10 cm, 10x15 cm, and 10x20 cm) and the subplot used the tuber cutting consisting of 3 levels (without cutting, cutting 1/3 parts, and cutting 1/4 parts). Data on growth and yield parameters were recorded and subjected to analysis of variance (ANOVA) at a 5% level. The results showed that there were no interactions between plant spacing and tuber cutting of the shallot^s growth and yield. The treatment of tuber cutting produced tangible growth and yield, but there were no significant differences between the kinds of plant spacing.

Abstract
Biduri (Calotropis gigantea) is a herbaceous plant that has a lot of potentials yet farmers do not cultivate it properly. For instance, many farmers apply inorganic fertilizers excessively which can damage the environment, so that they do not embody environmentally-friendly agriculture. One of the efforts to achieve sustainable agriculture is the use of organic fertilizers. This research was carried out from March 2021 to October 2021 at the screen house, field laboratory of Jumantono, Soil Biology laboratory, Chemistry and Soil Fertility laboratory, and laboratory of Plant Physiology and Biotechnology, Faculty of Agriculture, Universitas Sebelas Maret. This research used a Randomized Complete Block Design (RCBD) with two factors and three replications. The first factor is cow manure which consists of three levels: K0 = without manure, K1 = 10 tons/ha, K2 = 20 tons/ha. The second factor is mycorrhiza which consists of four levels: M0 = 0 g/plant, M1 = 5 g/plant, M2 = 10 g/plant, M3 = 15 g/plant. The data obtained were analyzed by analysis of variance and DMRT. The results showed that the interaction between cow manure and mycorrhiza was not increase the growth of biduri- giving a dose of cow manure 20 tons/ha gives best result for the yield of plant height, stem diameter, number of leaves, and number of branch- mycorrhizal administration was not increase the growth of biduri.

Abstract
CVPD is the most devastating disease on citrus production in Indonesia and in the world. It is vectored by Diaphorina citri. Guava leave extract is a prospective control means for reducing vector population. Research was conducted to investigate the repellent effect of guava shoots to adult of D. citri (psyllids) and the attractiveness to its predator Menochilus sexmaculatus. Repellent effect of grinded dried of upper, middle, bottom shoot of red, white, and non-seed guava shoots to D. citri and M. sexmaculatus of mixed gender were determined in Y-tube olfactometer. The result showed that guava shoots had repellence effect to D. citri. Highest repellence effect was found from white guava shoots, followed by non-seed guava and red guava. Repellent effect was 80.7%, 72.7%, and 70.0% respectively. However they did not have any repellent effect to M. sexmaculatus. Guava shoots had the attractiveness effect to M. sexmaculatus adult. The effect was higher on upper, middle, and bottom shoot of red guava, and white guava, and middle shoot of non-seed guava than on upper shoot of citrus. Exception phenomenon was found on upper and bottom shoot of non-seed guava. The attractiveness on those shoots was lower than on citrus leaves. It was able to use guava shoots to repel D. citri and to attract M. sexmaculatus adult as a part of control means of D. citri vector of CVPD disease.
