Abstract

Technology development in the 5.0 era has been rapid, including in education and sports. One example of technology in sports education is a sports skills test kit. This study aims to develop and test the cricket batting test robotic-based equipment using sensor cameras with the grid system. The experiment was carried out by measuring student responses regarding using a robotic-based batting test tool using a camera sensor with a grid system. This student response is useful for knowing the extent of student responses and reactions to the products used so that they can be used as reflection material and references in designing products. The research method used in this study is Research and Development. The instrument used in this study is a test instrument in the form of an observation sheet. Product validation is divided into two, media validation and learning evaluation. The final assessment results are 160 and 162, indicating that the product is very suitable for use. They are synchronized by looking for whether there is an effect of student responses on student abilities. The results show 53,4% of the effect of students' positive responses on the object's ability. Based on the study's results, it was stated that the development of the tool was feasible to use and validated by media transfer and evaluation experts. In addition, this research is also developing research inspired by previous research. Further research is needed on implementing modified tools to see the effectiveness of training using an Android-based cricket batting test tool using a sensor camera with a grid system.

Abstract

The Guci Sehati Farmer Group in Nagari Lasi faces several fundamental challenges in their agricultural practices, one of which is dependence on synthetic chemical fertilizers. These fertilizers lead to high production costs and trigger degradation of the soil's physical, chemical, and biological structure. The lack of knowledge about using nature-based materials is a challenge for implementing cultivation practices in this farmer group. Additionally, there is an abundance of locally available organic materials such as agricultural waste, weeds, and livestock manure that have not been optimally utilized for producing environmentally friendly fertilizers. This community service program focuses on technical mentoring for making Tithonia-based compost at the Guci Sehati Farmer Group, Kanagarian Lasi, Agam Regency. The main problems faced by partners are high dependency on synthetic chemical fertilizers, expensive agricultural inputs, and suboptimal utilization of local biomass such as Tithonia diversifolia which is abundant in the surrounding environment. The aim of this activity is to empower farmers with skills to make quality organic fertilizer to create more sustainable and independent agriculture. The implementation method includes three main stages: (1) socialization and direct demonstration of Tithonia composting techniques, (2) participatory assistance during the fermentation and turning process, and (3) monitoring and evaluation of compost quality. The mentoring results showed a significant increase in farmers' capacity, where all participants successfully produced Tithonia compost that met physical quality standards, namely dark brown color, crumbly texture, stable temperature, and no odor. The conclusion of this activity is that participatory technical assistance is effective in transferring Tithonia composting technology, reducing dependence on chemical fertilizers, and optimizing local resources, thus directly contributing to strengthening food sovereignty and implementing sustainable agriculture at the farmer level.

Abstract

Pakcoy (Brassica rapa L.) is a short-lived leafy vegetable with high nutrient requirements and is highly responsive to environmental conditions, making it well-suited for cultivation using hydroponic systems. Additionally, the limited availability of agricultural land in urban areas due to land conversion necessitates efficient cultivation methods that do not rely on soil. Hydroponic systems offer more precise control over nutrient management and the growing environment compared to conventional soil-based cultivation, potentially increasing production efficiency on limited land. The success of hydroponic pakcoy production is significantly influenced by the type of growing medium, which supports root development, maintains water availability, and facilitates aeration and nutrient absorption. Therefore, research on various growing media is essential to identify the most effective medium for enhancing pakcoy plant growth and yield. This study aims to: 1) determine the effect of various growing media on the growth and production of pakcoy plants in hydroponic systems (Brassica rapa L.); and 2) identify the best alternative growing medium for optimizing the growth and production of pakcoy in hydroponic cultivation. The research was conducted from May to July 2025 in the greenhouse of the Payakumbuh State Agricultural Polytechnic, Harau District, Lima Puluh Kota Regency, West Sumatra. This study employed a completely randomized design (CRD) with a non-factorial approach. The factor studied was the growing media, consisting of seven treatments: rockwool, bamboo humus, coconut fiber, chopped fern, rockwool + bamboo humus, rockwool + coconut fiber, and rockwool + chopped fern. The parameters observed included plant height, number of leaves, leaf width, leaf length, root length, and fresh plant weight. The results indicated that variations in growing media significantly affected the growth and production of Pakcoy plants in the hydroponic system. The combination of rockwool and coconut fiber as planting media yielded the best results for Pakcoy plant growth and production. Therefore, the optimal alternative planting media for Pakcoy growth and production in the hydroponic system was rockwool combined with coconut fiber.
