Abstract

The aim of the research was to study the effects of biological seed treatment utilization rhizobacteria on seed germination and seedling growth, furthermore to figure out the competence of rhizobacteria isolates to dissolve phosphate, produce acetic indol acid (IAA) and siderophore. 18 rhizobacteria isolates used in this research, each isolates was anlayze in vitro; IAA, phosphate and siderophore. Then carried out the in vitro test, the pepper seeds were inoculated with rhizobacteria isolates suspension then germinated. Seedlings were transpalated into a plastic pot filled with medium soil and compost (2:1). The germination was observed everyday until 14 days, the seedlings was observed at 4 and 6 weeks after transplating. Based on the study, all the rhizobacteria isolates produced IAA, 13 rhizobacteria isolates capable to dissolve phosphate and 12 rhizobacteria isolates produced siderophore. Seed treatment using RBNA 14, RBNA 13, RBKB 5, and RBSPA 14 adequate to increase the germination in seed viability and vigor also increase seedling growth

Abstract

Rhizobacteria play a positive role as biocontrol agents as well as Plant Growth Promoting Rhizobacteria (PGPR) agents. The research objective was to obtain indigenous rhizobacteria isolates on cocoa plants that have the potential to inhibit the attack of P. palmivora fungal pathogens, and act as PGPR in vitro and in vivo. The results of the study concluded that isolates TRI 7/1, TRI 8/8, GM 7/9 and GM 7/10 had the highest ability to inhibit the growth of pathogen. The lowest disease severity (20%) was obtained in the seedlings treated using isolates TRI 7/1 and TRI 8/8. Rhizobacterial isolates GM 3/6, GM 5/6, GM 7/9 and GM 8/8 produce high amounts of IAA. Rhizobacteria isolates GM 5/6, GM 7/9 and GM 8/8 has very high peroxidase enzyme activity. High production of HCN compounds was obtained in rhizobacteria isolates TRI 3/3, TRI 4/10 and TRI GM 8/11. All rhizobacterial isolates gave an increase in the value of maximum growth potential, germination and vigor values for growth strength compared with the control. The rizobacteria treatments using isolates TRI 7/1, TRI 8/8, GM 7/9 and GM 7/10 were able to increase plant height, stem diameter and number of leaves at 30, 40, 50, 60, and 70 DAP compared to control treatment.

Abstract

The tsunami that occurred in 2004 has changed various aspects of activities in West Aceh District. Particularly in the agricultural aspect, the damage occurred not only to cultivated land but also to the surrounding ecosystem. Particularly in the Meureubo sub-district there is a need for outreach to improve farming, where cultivated plants are often attacked by pests. So it is necessary to have proper and environmentally friendly control, one of which is by increasing the use of biopesticides derived from wild plants that are easy to find. Titonia is a flowering wild plant that has the potential to be a good source of nutrition for organic plants, T. diversifolia can be used as green manure, and there are several other studies which also state that titonia extract can be used as a vegetable pesticide in pest control. Using the direct field observation method, which aims to provide knowledge to farmer groups in Meureubo District, West Aceh to use Titonia as an environmentally friendly biopesticide in agricultural cultivation, where the future impact can restore the ecosystem on agricultural land by reducing the use of chemical pesticides. With the results of case study activities, namely biopesticide products that can be used by farmers, data on insects found on agricultural land, both pests, parasitoids, predators, and pollinators. The pests found on the cultivated land were Epilachna sp, Naupactus leucoloma, Piezodorus guildinii, Bemicia tabaci, Agromyza phaseoli, Nezara viridula, Spodoptera sp. By finding few types of pests, it means that the use of biopesticides can reduce the types of pests that attack agricultural land.

Abstract

The availability of digital data regarding geographic information has brought the changes in how we use and understand information about the earth. One of the sectors that needs to be improved and developed so that this data provision can be fulfilled is human resources, namely the ability to master mapping skills. This involves analyzing each employee's competencies in relation to specific skills, for example abilities related to specific projects, roles and tasks. The service method used is the lecture and direct demonstration method. Basic level GIS training activities for the community were held for 5 days from 16-22 March 2023, attended by  37 participants in total from various government agencies. This activity takes place in three stages, ie. the opening stage, the map making practice stage and the closing stage.

Abstract

Nutmeg (Myristica fragrans) is spice plant which has an important position as a source of essential oils. An important problem in nutmeg cultivation is white root disease which can reduce nutmeg production. Until now, white root disease is still a problem in nutmeg plantations in South Aceh district. One of the solution that can be explored as an environmentally friendly control measure is to use the botanical fungicide coconut shell liquid smoke. This research aims to determine the potential of coconut shell liquid smoke in controlling white root fungus in vitro. The research was carried out in the Plant Protection Laboratory, Faculty of Agriculture, Teuku Umar University. The research design used was a non-factorial Completely Randomized Design (CRD) consisting of nine levels of liquid smoke concentration treatment; control 0%, 0.5%, 1%, 2%, 3%, 4%, 6%, 8%, 10%. Each treatment involved three replications. Data analysis was carried out using analysis of variance and Tukey's least significant difference (HSD) test.The research stages carried out consisted of producing coconut shell liquid smoke, isolating white root fungus from the roots of infected nutmeg plants and potential assay of liquid smoke in inhibiting the growth of white root fungus. In vitro bioassay result showed that liquid smoke treatment 3% was the best treatment because it was the lowest concentration causing total inhibition of the growth of white root fungus.
