Abstract

Global food security and environmental stability will be threatened by population growth, land usage, and land change. Proper soil management in plant production helps reduce temperature and humidity-induced plant deterioration. This study aims to identify soil physics health (SPH), microclimate characteristics, and the relationship between the two in managing organic and inorganic paddy fields. The research location is in Purwantoro District, Wonogiri Regency, using descriptive explorative research, with purposive soil sampling at work map, made by overlay thematic maps, resulting in 9 LMU. The observation and sampling were carried out in the maximum vegetative phase of plants, while the micro-climate is in the generation phase. The determination of the soil physics health status used the scoring method. Using the T-test, Pearson’s correlation test finds the relationship between SPH and micro-climate characteristics and the differences between the two. The results showed the distribution of SPH in organic farming is healthy (74.7) and very healthy (83.3), while inorganic farming is healthy (79.72). The temperature is optimal, ranging from 23.5°C to 30.1°C, but the humidity is minimum in the range of 35.3% to 76.1%. The SPH and micro-climate have a significant relationship, with a positive correlation between air and soil temperature with SPH and a negative correlation between air humidity and soil moisture.

Abstract

Urban development and increasing population impact improving the demand for non-agricultural land. Through the issuance of Law No. 41 of 2009 concerning the Protection of Sustainable Food Agricultural Land, the government has attempted to reduce the conversion rate of agricultural land by protecting paddy fields that are considered the potential for food supply. This study aims to examine the impact of the transformation of agricultural land to non-agricultural land on food security and the implementation of the of Law No. 41 of 2009. The research method used is survey and descriptive. The focus of discussion includes population growth, land change, land area, harvested area, production and food availability needs data. The data was gathered from field observations, interviews and a literature study. The results showed that the average decrease in paddy fields in the last three years was 98.87 ha. The population density in Sleman Regency is classified as high. In 2018 to 2019 the population density increased by 22.88 people km-2. In 2019 to 2020 the population density decreased by 163.35 people km-2. In 2018 to 2019 rice productivity increased by 625 tons ha-1, although harvested area and production have declined. There is no correlation between the location of paddy fields, population and rice productivity. The food security condition in Sleman Regency is generally stable, but the site of paddy fields that continues to decrease yearly must still be a concern.
