Abstract

The conversion of agricultural land at a high enough rate may threaten the food security of the population. The agricultural land most vulnerable to conversion is the rice field. The aim of this study was to determine the changes in paddy fields from 2013 to 2020, the distribution of the transformation of paddy fields to other lands, and the factors that influence the conversion of paddy fields. This research was carried out by digitizing the on-screen image method in 2013 and 2020. The classification of land use results from digitization was tested for accuracy by determining the sample points in the GIS (Geographic Information System) application and then compared to the results of the field survey. In addition, an analysis of the changes in paddy fields was carried out by overlaying land use maps in 2013 and 2020. Observations and interviews with people whose land was changing were conducted on the factors affecting the change in paddy fields. Changes in land use over a period of 7 years (2013-2020), namely rice fields, decreased by 149 ha (7.36 percent ). Meanwhile, there has been an increase in the area in other land uses. The function of the paddy fields in the urban area of Pangkajene, Sidrap Regency, has become 18.69 hectares of land built, 59.42 hectares of mixed gardens, 23.13 hectares of open/empty land and 49.11 hectares of land. The factor that affects the conversion of paddy fields in the urban area of Pangkajene is the strategic location of the land, which causes the community to convert its land into a place of trade and services. The increase in the number of people requiring large land areas has led to the construction of many residential complexes in rice fields and the high selling price of rice fields, which encourages farmers to sell their land.

Abstract

Ruminant livestock development is largely determined by the carrying capacity of feed sources because the availability of quality feed is a major factor of success. The quality of natural grass that has been relied on so far must be improved by utilizing superior grass which produces better biomass and nutrients. Mulato grass (Brachiaria hybrid cv. Mulato) is one of the superior grasses that has not been widely cultivated in South Sulawesi. This study aims to look at the growth of mulato grass fertilized with different types of manure. The research design applied was a completely randomized design (CRD) with 4 treatments of giving fertilizers and 3 consecutive repetitions consisting of no treatment, administration of goat feces, treatment of cow feces, and treatment of layer chicken feces. The variables observed were plant height, plant length, number of tillers, and number of leaves which were carried out every week after being uniform. The results showed that the use of cow feces gave the best results on all variables measured in details of the best plant height 44.2 cm, plant length 68.3 cm, 70 pieces, and 11.3 tillers.
