  • Tingkat Perkembangan Nematoda Puru Akar (Meloidogyne spp.) pada Berbagai
           Jenis Tanaman Tomat Menggunakan Pengendalian Ekstrak Daun Kirinyuh

    • Authors: KIKI AMELIA RAMADHANY, I MADE SUDANA, I DEWA PUTU SINGARSA
      Pages: 286 - 293
      Abstract: Development Rate of Root-Knot Nematode Meloidogyne spp. in Various Types of Tomato Plants Controlled with Siam Weed Extract The tomato plant, which is included in the Solanaceae family, is an annual herbaceous plant with a height between 70-200 cm, depending on the variety. Susenas (2012) reported that the average growth of tomato consumption in Indonesia in 2007-2011 is 2.1%. Based on data from the Central Statistics Agency (2005) in Taufik et al. (2014), tomato production in 2012 experienced a decrease in the amount of production from the previous year (2011), from 954,046 tons to 893,463 tons. Meanwhile, domestic demand for tomatoes in 2012 amounted to 904,000 tons, resulting in 10,537 tons of imported tomatoes (Pusdatin, 2014). One of the causes of the decline in tomato production is the disruption of plant pests, leading to failure. One of the diseases that attack tomatoes at all stages of growth is a root-knot disease caused by the nematode Meloidogyne spp. that live in plant nodules. Control of Meloidogyne spp. was done by using trap crops, crop rotation, and so on. In this study, we used biological control, using Siam weed leaf extract (Chromolaena Odorata L.). The results showed that the high level of development in tomato plant varieties could be known through the research data, including the number of roots and egg masses. The number of eggs indicated that the yellow cherry variety was higher than the varieties of red cherries, swadesi, serpo, and agata.

    • Authors: DEWA AYU DIAH PUSPITASARI, I PUTU SUDIARTA, I MADE SUDARMA
      Pages: 294 - 307
      Abstract: Identification of Bacteria Causing the Main Diseases in Hydroponic Plants Hydroponics is a horticultural cultivation technique using water as its growing medium. As the times progressed, people began to switch to planting with a hydroponic system, but this system was not completely free from pathogen attacks, one of which was bacteria. Therefore, this study aims to identify the types of bacteria that can infect hydroponic plants and determine the percentage of disease in hydroponic plants. The research implementation includes (1) calculating the percentage of disease, (2) sampling, (3) symptomatic plant isolation, (4) inoculation, (5) morphological classification, (6) detection of bacteria by PCR (Polymerase Chain Reaction), and sequencing analysis. The results showed that the percentage of attack on three plants, namely lettuce with soft rot symptoms, was 31.6% and celery with bacterial blight symptoms was 56.1%. The highest attack percentage was on tomato plants with bacterial wilt symptoms, reaching 69.1%. PCR results showed DNA bands measuring ± 1500 bp using general 16S rRNA primers (27F forward and 1492R reverse) on the three plants. Sequence analysis was continued on bacterial isolates from tomato plants because they had the highest percentage of attack. The nucleotide analysis of bacterial isolates in tomato plants indicated that the bacteria were a genus of Pseudomonas sp. Homology level of Pseudomonas sp. from Kesiman Village, East Denpasar District, Bali, after being traced and matched to the GenBank data in the NCBI program, it has similar homology with Pseudomonas from Iraq and India with a homology level of 89.86%, as well as from Egypt, New Zealand, and Germany with a sequence homology level of 89.19%.

      Abstract: Identification of the Fungal causal Agent of Main Diseases in Hydroponic Lettuce (Lactuca sativa L.) Hydroponics is an agricultural cultivation system without using soil but using water-containing nutrient solutions. Hydroponic technology is used as an alternative in plant cultivation to maintain optimal plant growth. It is completely protected from the influence of external elements such as rain, pests, climate, and others. One of the plants that are often cultivated in hydroponic technology is lettuce. However, in practice, hydroponic lettuce plants are also faced with the constraints of pathogenic fungi that cause disease in cultivated plants. This research was conducted to identify pathogenic fungi that cause disease in hydroponic lettuce plants. The results showed that the disease in hydroponic lettuce was a leaf spot disease caused by Cercospora sp. and wilt disease caused by Fusarium sp. Leaf spot disease is the main disease with a disease percentage of 41.90%.

      Abstract: Induction of Chromosome Mutations with Colchicin in Red Grape (Vitis vinifera L. Prabu Bestari Varieties) Through In Vitro Callus Formation This study aims to determine the colchicine concentration that can induce chromosome mutations in red grape, carried out in vitro. This study used a completely randomized design (CRD) with 9 treatments and 3 replications so that the number of experimental units was 27 bottles of culture. The sterilized red grape node explants were immersed in colchicine at the concentration according to the treatment for 24 hours. The colchicine concentration used was 0.015% (K1), 0.020% (K2), 0.025% (K3), 0.030% (K4), 0.035% (K5), 0.040% (K6), 0.045% (K7), 0.050% ( K8) and 0% (K0) as controls. The effect of immersion in several colchicine concentrations on chromosome mutations in explants of red grape nodes that form callus cannot be observed because the chromosomes are not clearly visible, and the number of chromosomes cannot be calculated. Callus was formed in colchicine immersion treatment with a concentration of 0.015% (K1) and 0.035% (K5). Callus on K5 was formed faster, namely 10 weeks after planting, while K1 was at 11 weeks after planting. The average callus diameter on K5 was larger with a size of 4.3 mm, while on K1 it was 2 mm.

      Abstract: Land Suitability Evaluation of Several Horticultural Crop Commodities Based on Geographic Information Systems in the Subak Area of West Denpasar This study aims to determine the actual and potential land suitability, limiting factors, assumptions of improvement efforts, making land suitability maps, and land use direction maps for vegetable and flower horticultural crops. The plants evaluated included spinach, mustard greens, eggplant, marygold, and sunflowers. This research was conducted in West Denpasar from December 2020 to March 2021. Based on the distribution of subaks in West Denpasar, there are eight subaks. The research method used survey methods to evaluate land suitability, soil analysis, and use matching methods between land quality/characteristics and plant growth requirements evaluated by Ritung et al., (2011). The results showed that the actual land suitability classes for vegetable and flower horticultural crops were classified as S1 (very suitable) to S3 (according to marginal). Land characteristics that act as limiting factors include temperature, drainage, texture, N-Total, and K2O. Improvement efforts can be made by adding fertilizers and constructing a drainage system channel, except for the limiting factor of temperature and texture, which are permanent limiting factors. The potential land suitability classes for vegetable and flower horticultural crops evaluated were S1 (very suitable) to S2 (quite suitable), with a temperature limiting factor. Based on land suitability and limiting factors for land use recommendations that can be developed in West Denpasar, namely eggplant, marygold, and sunflower, horticultural crops have more priority than spinach and greens mustard.

      Abstract: Utilization of Azotobacter Bacteria to Increase the Efficiency of Urea Fertilizer Use in Rice Plants (Oryza sativa L.) Rice is a food plant in the form of grasses (Gramineae) originating from the tropical and subtropical continents of Asia and West Africa. Nearly half of the world's population, including Indonesia, uses rice as the staple food consumed to meet food needs. Based on BPS data, the population shows an increase every five years. It is inversely proportional to the decreasing total rice production. One of the efforts to improve the cultivation technology package and increase the quality of intensification is the use of Azotobacter bacteria as a biofertilizer. Based on the isolation results, 52 Azotobacter isolates were found grown on Abhys mannitol agar. Based on the results of the selection of Azotobacter bacterial isolates, it was found that four Azotobacter bacterial isolates had the best effect on root growth of rice plants, namely the Azotobacter PD3, PD23, PD48, and PD51 bacterial isolates. The test results with GC-MS showed that 2 compounds were thought to contribute to increasing the growth of rice plants. These compounds were n-Hexadecanoic acid and oleic acid, which were included in the fatty acid group. The isolates of the Azotobacter PD3, PD48, PD51 bacteria were able to increase the efficiency of using urea by 25-50%. In comparison, the PD23 bacteria were able to increase the efficiency of using urea by 25% based on the number of tillers.

      Abstract: The Effect of Planting Media and Varieties on the Yield of Melon (Cucumis melo L.) in Drip Irrigation Systems Melon (Cucumis melo L.) is a fruit crop including the family Cucurbitaceae. Melon is not a plant native in Indonesia but can grow in the tropical region. This fruit is very popular in the community and is often used by hotels as a welcome fruit. Badan Pusat Statistik's (2019) data stated that melon production in Bali increased in 2019 to reach 552.00 tons. This study aimed to obtain the appropriate planting medium for melon cultivation by drip irrigation systems in a greenhouse. The treatments consisted of three types of planting media: husk charcoal media, cocopeat, husk charcoal mixture with cocopeat, and melon varieties suitable for cultivation in a greenhouse using drip irrigation. The results showed the treatment of cocopeat could increase the development of melons. Cocopeat (Mc) can be increase the yield and quality of melons, and this can be seen in the fruit weight (1,214.50 g/plant) and total dissolved solid (11.87 0briks). Golden melon variety (Alisha F1) was able to produce sweeter fruit (11.97 0brix), but the fresh weight was lower (887.33 g / plant).

      Abstract: The percentage of Bean Common Mosaic Virus (BCMV) carried by seeds and detection of virus position inside long beans (Vigna sinensis L.) seeds in Bali Long bean (Vigna sinensis L.) is a horticulture crop with an essential economic value in Indonesia and Bali. Long beans productivity in Bali reached 6023 tons in 2013, and decreased to 5157 tons in 2014. Cases of disease that lowers the production of long beans in Bali were caused by Bean Common Mosaic Virus (BCMV) infection by 56.06%. BCMV can be brought by the seeds (seed-borne disease) and can infect long beans plants since the early stage of development. This research aims to evaluate the percentage of BCMV transmission by commercial long beans seeds, commonly used by farmers in Bali, and observe the location of BCMV inside the seeds. The morphological observation was used to evaluate the percentage of BCMV brought by the seeds by observing BCMV specific symptoms appear on two weeks old long beans seedlings. To observe the location of BCMV inside the long bean seeds, harvested seeds from an infected plant were separated to collect the cotyledon and embryo. The RT-PCR technique was used as a method in this research. The result showed the percentage of BCMV brought by long beans seeds used by farmers in Bali categorized as high. The percentage of BCMV brought by seeds from the highest to the lowest were; variety A 48.39%, variety B 46.66%, variety C 43.59%, variety D 37.83%, variety E 22.86%, and variety F 22.72%. The variation of the symptoms was mosaic vein banding, malformation, and dwarf plant with wrinkled leaves. The BCMV brought by long bean seeds was resides on the embryo.
