Penerapan Teknologi Budidaya Jenuh Air dan Asam Humat pada Padi Toleran Salinitas di Lahan Terdampak Rob di Pekalongan

Abstract

The objectives of this activity are: 1) disseminating saturated soil culture technology and humic acid to farmers in tidal flood-affected lands, 2) increasing the cropping intencity in tidal flood-affected lands. This activity was carried out in Degayu Village, North Pekalongan District, Pekalongan City. The activity took place from June to December 2025. The implementation method was carried out by: 1) coordinating with the Staff of the Pekalongan City Agriculture and Food Service, and the Agrotechnology Lecturers of Pekalongan University; 2) field surveys, 3) socializing the application of saturated soil culture technology and humic acid through training, 4) making rice planting demonstration plots, and 5) harvesting rice yields. The results show that Degayu Village, Pekalongan City has experienced the impact of tidal flooding since 2012-2024, so that the rice fields that were originally class I, became unusable for rice, due to high salinity pressure. In 2024, the construction of the embankment on the coast of Degayu Village was completed, so that in the first dry season between February and June 2025, it was replanted and able to produce 5.2 tons of HDG (Harvest Dry Grain) rice per hectare using the Biosalin 1 variety. Salinity issues still arise in the second dry season between June and September 2025, because the high dry season causes the EC (Electrical Conductivity) of rice fields to reach 7-9 ds/m, even though rice requires a EC of rice fields below 3 ds/m. Planting the Biosalin variety of rice using the Saturated Soil Culture Technique (SSC) and the application of humic acid showed normal growth, and yields can still reach 3 tons of HDG per hectare. Conventional rice planting (flooding) causes rice plants to die.
