Isolasi Jamur yang Berasosiasi dengan Kumbang Ambrosia pada Pohon Angsana (Pterocarpus indicus)

Thu, 23 Nov 2023 00:00:00 +0000

Insect pests are organisms that can damage plants and have a high level of damage. However, it is not only insects that need to be watched out for but also the microorganisms they carry inside and outside their bodies. These insects are referred to as vectors. Ambrosia beetle is a plant vector that carries both saprophytic and pathogenic fungi. There is little information about ambrosia beetles and the mushrooms they carry, so they need to be studied further. This study aimed to determine the fungi associated with the ambrosia beetle on Angsana trees (Pterocarpus indicus). The research used purposive sampling by examining the symptoms and signs of an ambrosia beetle attack. The identification process is based on morphological forms and entomology manuals. The results obtained based on morphological identification showed that the ambrosia beetle came from the genus Cryphalus sp. In contrast, the associated fungus comes from the genus Geosmithia sp. It is known that the fungus Geosmithia sp. can act as a pathogen so that it can damage Angsana trees.

Beans (Phaseolus vulgaris) are widely cultivated by farmers in several regions in Indonesia, one of which is in CV. Reja Mayur Pacet, Mojokerto. Beans (Phaseolus vulgaris) is a type of legume that is usually used as a cooking ingredient.Obstacles that are often experienced in the cultivation process cause the quantity and quality of production to decrease, namely the attack of disease-causing pathogens on plants. The study was conducted in November-December 2022. The research used observation methods, literature studies, active participation, and interviews. The data collected are the type of disease in chickpea plants, symptoms of the disease, and the technique of controlling the disease. The results of the study found that there are 3 types of diseases that attack chickpea plants in CV. Reja Mayur, namely leaf rust, anthracnose, and mosaic. Some of the control techniques applied are the use of PGPR, crop rotation, mechanical control, and the use of vegetable pesticides.

Liquid organic fertilizer (LOF) based on local ingredients is expected to increase corn productivity in regosol soil. The purpose of this study was to find out the best dose to increase the growth and yield of corn in Bantul regosol soil. The methodology used a complete randomized block design with 6 treatments (control, very low POC dose of 5 ml/l, Low 7.5 ml/l, Moderate 10 ml/l, High 12.5 ml/l and Very High 15 ml/l) each of which was repeated 4 times so that there were 24 treatments. Observation of vegetative - generative growth and yield of corn plants. The collected data were processed and analyzed statistically using variance (ANOVA/Analysis Of Variance) and followed by a follow-up test at the 5% level of significance to see differences between treatments. The results showed that the best Megarhizo POC dose was 7.5 ml/l, this was indicated by the optimum plant growth and the highest maize yield of 10.26 tons/ha compared to other treatments.

Utilization of vinasse waste as POC has great potential in the agricultural sector. This is because there is an abundance of vinasse waste originating from the bioethanol industry sector. So action is needed so that vinasse waste can be utilized into a profitable product. This research aims to test the potential of vinasse waste if it is processed into POC. Apart from using vinasse waste as the main raw material, the formula also added organic ingredients such as straw ash, humate, husk charcoal and filter cake dregs which were fermented for 5 weeks. Based on the research results, the content of N, P, K and C-organic elements cannot comply with the 2019 Ministry of Agriculture Quality Standards. Meanwhile, the content of Na and pH elements is appropriate, but for Fe only the F2 and F4 T1 treatments can be appropriate.

Pengaruh Pemberian Pupuk Daun dan Pemangkasan Terhadap Produksi Belimbing (Averhoa carambola L.)

Flower and fruit loss and low fruit quality are complex problems faced in star fruit cultivation. The research aims to determine the effect of pruning twigs and applying foliar fertilizer on plant growth, quantity and quality of fruit. Factorial research using two treatment factors. . Factor I is the type of foliar fertilizer, consisting of D0 = No foliar fertilizer (control), D1 = SB foliar fertilizer (8-20-15), D2 = HP foliar fertilizer (10-40-15), and D3 = DN foliar fertilizer (10-30-37). Factor II is the interval for applying foliar fertilizer, consisting of I1 = once every 7 days interval, I2 = once every 10 days interval, and I3 = once every 14 days interval. The research used plant material of the same age, as replications, groups of plants were used that were differentiated according to the pruning model, namely P0 = Plants that were not pruned as replication I, P1 = Plants that only had their wiwilan branches pruned as replication II, and P2 = Plants that had their branches pruned wiwilan and clustered branches (remaining the good ones) as repetition III. The results showed that application of foliar fertilizer and pruning of branches increased the number of fruit, fruit weight and size of sweet star fruit. Pruning wiwilan branches and reducing clustered branches has the greatest effect on the number of fruit, fruit weight and fruit volume compared to other pruning intensities. The research results can be used as a reference for star fruit farmers in determining maintenance actions, especially in fertilizing and pruning to regulate the canopy. while increasing production.
