Abstract

Soil fertility is the ability of the soil to provide the nutrients needed by plants in adequate quantities and in a form that can be absorbed by plant roots. The aim of this research is to determine the level of soil fertility in the Aek Kundur river area regarding factory waste disposal in Lingga Tiga Village, District. West Bar. This research was carried out in June 2024 in Lingga Tiga Village, Bilah Hulu District, Labuhanbatu Regency with an altitude of 28 meters above sea level with coordinates N: 98022'44.34" E: 02032'34.23". Analysis of the physical and chemical properties of soil was carried out at the Laboratory of the Faculty of Agriculture, University of North Sumatra using an exploratory-descriptive survey method. Research results on the physical properties of the soil in Lingga Tiga Village have a clayey clay texture and in Liga Tiga Village have a clay texture. Furthermore, the chemical properties of the soil in Lingga Tiga Village have criteria, namely neutral pH, low organic C, moderate P2O5 and low soil fertility status in the Aek Kundur river area against factory waste disposal. For this reason, fertilization treatment is needed to improve soil fertility status.

Abstract

The pak choy plant is a plant that has a very easy method of cultivation. The pak choy plant is also one of the vegetables that is often developed by hydroponic farmers because many people like to eat pak choy so this plant is one of the people's favorites. The aim of community service (PKM) is that the community is expected.  Efforts to increase the productivity of pak choy continue to be made because this plant has quite high economic value and market interest. This service uses the lecture method, namely by conveying information and knowledge orally using power points. By using Sonic Bloom technology on Pakcoy plants, you can stimulate the opening of the stomata, thereby influencing the movement of carbon dioxide around the plant, thereby influencing the absorption of carbon dioxide around the leaves and more importantly using high frequency and organic sound waves. nutrients, which are proven to grow plants better to increase their productivity. By implementing this community service program, the Karang Taruna Tani Pasir Mas Group Partners will be able to provide knowledge in cultivating vegetables using Sonic Bloom technology. And based on this report, it can be concluded that Sonic Bloom treatment using the sound of the Al Quran can produce plant height, number of leaves, production weight and weight of basal roots and dry roots in bok choy plants because the sound is given using a high frequency. can stimulate the leaf mouth (somata) to remain open.
