Abstract

The high demand of rice is fulfilled by intensification, particularly with the use of chemical fertilizer that allegedly causes land and environmental problems in a long term. As public awareness of environmental health rises, more rice fields are managed organically and semi-organically, but there are still many that manage rice fields inorganically. Assessment of soil quality of the three types of rice field management is important to prove that organic rice fields have better soil quality than semi-organic and inorganic rice fields, as well as to evaluate soil conditions on the location. This research was conducted in Girimarto, Wonogiri, Indonesia, using a descriptive explorative method with a survey approach on three points of each management system of rice fields, which are organic, semi-organic and inorganic rice fields. Statistical analysis was performed by Pearson correlation analysis and principal component analysis (PCA) to determine the indicators affecting soil quality, which are called the minimum data set (MDS). There were selected indicators in this research, including total microbes, base saturation, cation exchangeable capacity and organic carbon. Based on the results of the study, organic rice fields have the best soil quality with a score of soil quality index (SQI) of 2.3, compared to semi-organic rice field SQI (2.2) and inorganic rice field SQI (1.7). The results indicate that organic management contributes to better soil quality and environment.

Abstract

P fertilization can add Cd metal content to agricultural land because the raw material for making P fertilizer comes from phosphate rock which naturally contains Cd metal. Farmers assume that by providing fertilizers with high doses can provide maximum results. Community’s knowledge of heavy metals in the environment is still low. This study aims to examine the awareness of farmers in Sragen Regency Central Java to the potential of heavy metal pollution that occurs. This research was conducted from July to December 2017. The type of this research is quantitative descriptive research using a questionnaire with the number of respondents amounting to 10% of the number of farmers, namely 30 farmers. The results show that about 61.11% of the community doesn’t understand that the presence of heavy metals in the environment can cause many problems. About 60% of the community doesn’t understand that the inorganic fertilizers commonly used by them contain heavy metals (especially Cd metal). People unaware of heavy metal pollution due to over-fertilization is 65.01%. Although the community's knowledge and awareness of heavy metals are still low, the community awareness about environmentally friendly agriculture is high (61.33%). About 53.34% of the community doesn’t know that their behavior in using inorganic fertilizers in the long term will increase the accumulation of Cd metal in agricultural land and rice plant tissue. About 70% of the community doesn’t know that agricultural land that is used continuously to plant (without interspersed with non-paddy crops) will cause land degradation.

Abstract

Soil quality is the ability of the soil to perform its function, such as providing nourishment to the plants. However, intensive paddy farming, such as Hazton’s paddy farming method, is suspected to deteriorate soil quality status and degrade land sustainability. This study aimed to analyze soil quality under Hazton’s paddy farming. This study was conducted on paddy fields in Banyumas Regency using a randomized block design with treatment consisting of 1) conventional method as a control, 2) Hazton’s method + organic fertilizer, 3) Hazton’s method + organic fertilizer + decomposer, and 4) Hazton’s method + organic fertilizer + decomposer + leaf fertilizer. Soil quality was determined according to a minimum data set (MDS) that consisted of organic C, pH, total N, available phosphorus (P) and potassium (K), base saturation (BS), cation exchange capacity (CEC), bacterial density, soil respiration, and C/N ratio. The MDS was scored and calculated using the soil quality index formula and then classified from very low to very high (<0.19-1). This study highlighted that the soil quality in paddy farm using Hazton’s method in Banyumas Regency ranged from low (0.444) to very low (0.308). The application of organic fertilizer is not sufficient enough to refill the nutrient pool equal to harvested plant biomass. This leads to soil quality deterioration and affects land sustainability. Therefore, yield and biomass production should be included as soil quality indicators in future studies. Additionally, further soil degradation can be avoided by continuously assessing soil quality and the necessary conservation measures for preventing and minimizing further land degradation can be applied.

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.

Abstract

Agricultural land in Sleman Regency has changed many functions, including constructing toll roads and settlements. The conversion of agricultural land to non-agricultural land, without being balanced by the creation of new farmland, resulted in the threat of crisis. This research aims to adjust the spatial plan and its application in the field to suppress and control the rate of agricultural land conversion, thus supporting the maintenance and the realization of food security and good health. It was implemented in the Sleman Regency area covering 17 sub-districts. This research uses the institutional survey method, which collects secondary data from development policies and programs from relevant agencies via email, website or coming directly to the office. The results show that the total area of agricultural land conversion in Sleman Regency is 69.93 ha per year. Agricultural land needs to increase its size by 356 ha in 2019 to meet the demands of the applicable laws and regulations. Land use unrelated to the area's function can impact ecological imbalances and potential disasters. Efforts to optimize land use include land certification, granting, signage and tightening permits. Finally, this research study concluded that by optimizing land use, it is hoped that it will be able to maintain and realize food security and good health, especially in Sleman Regency.

Abstract

Siamese oranges are one of the most widely developed horticultural crops in Indonesia. Arjosari and Ngadirojo are some of the sub-districts that produce Siamese orange in Pacitan Regency. One of the factors that can affect the development of citrus is land quality. This study aims to obtain land quality index data and improvement efforts for developing Siamese orange. Soil samples were taken from 25 land mapping units (LMUs) with 87 sample points. The soil sampling points were determined based on area or sampling density. Data analysis used for soil quality assessment includes correlation, principal component analysis (PCA), minimum data set (MDS), and calculation of climate quality index. The parameters used in this study are bulk density, porosity, moisture content, texture, pH, electrical conductivity (EC), cation exchange capacity (CEC), base saturation, total N, available P, available K, soil organic carbon (SOC), microbial biomass carbon (MBC), evapotranspiration, temperature, and solar radiation. Based on the results of soil quality analysis in the study area, it has a value range of 0.28 to 0.37, including low class, while the climate quality index is 1.39 with moderate class. The land quality index has a very low to low class with a value of 0.39 to 0.51. Intrinsic, extrinsic, and anthropogenic factors can influence soil quality. The study area’s limiting factors for developing Siamese oranges are EC, total N, and available P, which can be improved by making furrow ponds, adding organic fertilizer, using urea fertilizer, and SP36 according to the dosage.
