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.

Abstract

The limited knowledge owned by KWT Sekar Arum in seedling hydroponic plant seeds and lack of manpower to maintain the seedlings caused the seeds produced to be poor (small stems and few leaf shoots) and some were eaten by pests. Poor seeds produce plants that are not optimal. Therefore, in this community service activity, a nursery chamber is designed for seedling hydroponic plant seeds that utilize solar panel energy as a source of electrical energy in indoor hydroponic plant seed cultivation. This nursery chamber is equipped with artificial light and automatic irrigation so the seedling process can save energy and time. Artificial light is made using 2 types of LED lamps with a red spectrum and a blue spectrum arranged at a certain distance so that the intensity of the light produced is 100 mol/m2/s. To be utilized optimally, all members of KWT Sekar Arum were given counseling and training related to the use of the nursery chamber. In addition, KWT Sekar Arum is also assisted in the process of transplanting and maintaining hydroponic plants so the results are maximized. Based on the results of the evaluation, it can be seen that the transfer of technology provided can be utilized properly by KWT Sekar Arum, the seeds produced from the nursery chamber already have 3-4 leaf shoots when they are 9 days old and ready to transplant, and the results of hydroponic plants produced has been maximized with wide and many leaves.

Abstract

Sandy soil is characterized by a coarse texture, low organic content, low water-holding capacity, and rapid leaching. Soil amendments are usually applied to improve soil physicochemical characteristics, but their effects are only short-term. Subsurface hybrid ameliorant layering has been proposed as a means to reduce leaching in sandy soils. This study evaluated the leaching responses to subsurface hybrid ameliorant placement within the soil, using a soil column experiment with two factors: kinds of HLU (Homogeneous Land Unit) as the first factor, which consisted of eight HLUs, and ameliorant placement treatments as the second factor, which consisted of control treatment, conventional placement, and subsurface placement. The leaching response parameters were cumulative leachate volume and the differences in organic carbon, nitrogen, and phosphorus concentrations between the upper and bottom layers. The results showed that subsurface placement can reduce the cumulative leachate volume and increase N concentration in the upper layer after the incubation period, but did not significantly affect organic carbon or phosphorus availability in either layer. The application of this treatment resulted in different responses among HLUs, which were influenced by the natural physicochemical characteristics of the soil.

Abstract

Unpredictable weather conditions during the traditional drying process pose a challenge to shallot farmers in the Rejeki Lancar farmer group in Karanganyar Adipala village in reducing yield losses. Adequate water content is essential for maintaining the quality of shallots ready for sale and storage. Therefore, a drying technology capable of maintaining and improving shallot quality is needed through the use of an electric drying machine. The community service project was implemented using the community-based research (CBR) method with a participatory approach by the farmer groups. The  activity stages included observation and discussion, tool design and construction, tool testing and calibration, training and mentoring, and evaluation. The implemented drying machine can dry shallots in 21 hours, whis typically takes 7-9 days. This community service activity increased farmers knowledge and skills in shallot drying technology by 15,71 %. In addition to shortening the drying process, the electric-powered drying machine produces a more uniform moisture content, resulting in improved and more consistent shallot quality. The implementation of this technology is expected to reduce postharvest losses and enhance the competitiveness and sustainable income of shallot farmers.
