Abstract

Zoysia matrella is a type of highly valued grass, but the seedling time is very long due to the slow growth rate. Several studies have been conducted using artificial light as a light source to accelerate indoor plant production. However, this technology is yet to be widely used for seed production. Therefore, this study aimed to obtain optimal light intensity from artificial light in accelerating Zoysia matrella seedling time. The treatment in the form of Light Emitting Diode (LED) illumination given to increase the growth of Zoysia seedlings consisted of 5 levels, namely 20, 40, 60, 80, and 100 (μmol/m2/s). The parameters studied were germination percentage, germination rate, and vegetative measurement in the form of seedling height in Zoysia nursery chamber equipped with artificial light. The results showed that the artificial illumination technology in the nursery chamber increased the speed of seedling time in the germination and growth phases of Zoysia seeds.

Abstract

The continued reliance on shallot seeds is a significant challenge, primarily due to the high production costs associated with seed cultivation. To address the high production costs associated with shallot seeds, horticultural farmers within the Rejeki Lancar Farmer Group have endeavored to cultivate shallots from seeds. Nevertheless, the efficacy of the seeding technique remains relatively low. This is attributable to the specific land and climate conditions that prevail in this region. Considering the challenges encountered by this group, the proposed community service activities prioritize the acceleration of seedling growth, the enhancement of seedling quality, and the optimization of production costs for shallot seeds. This is achieved through the construction of a seedling rack equipped with artificial light. This community service activity utilizes a problem-solving approach based on the existing issues within the partner group, combined with a technology-based solution approach. The implementation of the community service program begins with observations at the partner site, followed by discussions with the partner regarding needs analysis and the suitability of the technological resources mastered by the community service team. This is followed by the preparation of technological media/tools, dissemination and training on the operation of the tools, and an evaluation of the activities. This activity demonstrates the high level of interest among residents in accelerating the production of red onion seeds from seeds. During the trial process, within two days in the germination rack, the growth of the seeds was observed to be significantly faster compared to traditional seedling production, which typically requires more time.
