The area of agricultural land, especially paddy fields, is related to the level of rice production. Conversion of agricultural land to non-agriculture will have an impact on the availability of rice supply. This study aims to identify changes in paddy field land use in 2005 - 2016 using high-resolution satellite imagery and calculate the need for rice per capita in Pallangga District. This research utilizes the application of geographic information systems in monitoring changes in paddy field use. The method used in the classification of land use is digitizing on screen. The conversion of paddy fields to non-paddy fields was obtained from the results of overlapping maps of Pallangga District land use maps in 2005 and 2016 and presented in the form of cross tabulations. The accuracy test results obtained the overall accuracy value of 98.04%, and the kappa accuracy value of 0.98. This study shows that paddy field area has decreased by 305.25 ha. The change consisted of 17.68 ha into a water body, turned into a garden of 132.86 ha and became a settlement of 154.71 ha. The conversion of paddy fields in Pallangga District in 2005-2016 affected rice production. The results of the analysis of the needs of rice per capita per year show that in 2017 Pallangga District is surplus in the supply of rice to its population. However, based on population projection, the decrease in land area and rice production in Pallangga Subdistrict in 2020 was unable to meet the rice needs of its population of 1,027 tons

Organic material derived from horse manure is very abundant and has the potential to be used as organic fertilizer with good nutrient content for plants. This study to utilize organic manure from combustion for growth and productivity of the red chili. In addition, this research was conducted to obtain the right composition of fertilizer doses to increase the growth and production of curly red chili. The method to use the Alfisol soil growing media at the site using polybag by treating different doses on each treatment. The number of treatments were given doses of 0 g (P0), 1 g (P1), 284 g (P2), 426 g (P3) and 568 g (P4) with replications each three times. Analysis metode for use macro nutrient content (N, P, K) and data collection in the form of plant height, leaves, production and environmental factors. Data analysis used Duncan α 0.05. The results of the analysis of the treatment effect on plant height were P4 (Media of soil with combustion horse fertilizer from 568 g) treatment significantly different from other treatments. While other treatments did not show a significant difference in plant height. The effect of treatment on the number of leaves showed no real effect. In the growth and production of curly red chilies there are markedly significant differences. P4 is significantly different from P3, P2, P1 and P0. Whereas P3 is not significantly different from P1 as well as P2 which is significantly different from other treatments. P4 is a treatment with a large number of fruits with an average of 10.3 pieces. While treatment with a small number of fruits is P0 with an average of 2.3 fruits. Combustion horse manure organic fertilizer is quite effective in increasing the growth and production of red chili. It can be assessed from the development of plant height and number of fruits on curly red chili plants. The dose of horse manure organic fertilizer which is good enough for curly red chili plants is 568 g.

The hydrological process that occurs in a watershed is related to erosion process, sediment transport and downstream deposition. Land use changes and watershed management practices will also affect erosion and sedimentation. The purpose of this study was to determine the magnitude of flowrate, suspended load concentration (suspended load), and floating sediment discharge and correlation of floated sediment discharge and flowrate at the Data’ River. Measuring river characteristics is done by measuring river water flow and river slope. Sediment collection floated with EWI (equal with incerentment) method. Laboratory analysis was carried out by calculating the amount of flow discharge, sediment concentration, and sediment discharge. The results showed the lowest amount of flow discharge occurred on 17/12/2016 with a value of 0.271 m3/s with a floating sediment concentration of 17.167 mg / L, and the sediment discharge floated at 0.402 tons/day. The correlation between flow discharge and floating sediment discharge using a sccatter diagram shows that the determination value R2 is 0.9754 with the equation y = 0.1x + 0.4355.

Land use that is incompatible with the function of land can lead to negative effects, therefore it is necessary to set the direction of land use change in land use. This study aims to determine the dynamics of land use during the period of 15 years (1999-2013) and determine the fit between the spatial patterns of spatial plans with the actual land use in Rumbia and Kelara, Jeneponto. The study was conducted through data collection and analysis of data, the data used include primary data and secondary data obtained through observation, field observations, and other supporting data. Data already collected subsequently analyzed by using descriptive and quantitative analysis by means of data interpretation and overlay maps with GIS systems. The results of the study show that obtained six classes of land use consisting of forests, gardens, settlements, rice fields, shrubs and moorings / fields indicate that land use has decreased by 2.66% in 1999, 2004 by 1, 44%, and in 2013 decreased to 1.09% and those that experienced an increase in area were fields / fields of 50.44% in 1999, in 2004 it increased to 62.10%, and in 2013 the area increased to 69.52%.

Land potential can be assessed from biophysical land suitability including soil characteristics, climate, and land management. This study aims to determine the potential of paddy fields in Duampanua Sub-District, Pinrang District for irrigated paddy field based on the land biophysical characteristics. The method was qualitative and quantitative approaches. Field surveys use purposive sampling method with 3 object observation. The land suitability class evaluation uses a simple limiting factor approach according to FAO (1976). To support the analysis of rice production data, 30 farmers were interviewed in 3 (three) observation units. The results showed the average rainfall of 2,780.2 mm/year with 9 wet months and 3 dry months categorized as type B2 (Oldeman). The results of soil samples analysis showed the characteristics of the soil with a silty clay texture, silty clay loam and clay; bulk density ranges from 1.36-1.66 g/cm3; cation exchange capacity ranges from 49.64 - 79.75 cmol/kg clay; soil pH ranges from 5.26-5.97; base saturation ranges from 36% - 46.4%; and C-organic ranges from 1.34% - 1.38%. The most dominant types of minerals are orthoclase, biotite, pyroxene, augite, opaque and clay with the symptoms of micropedological concretions and nodules. The land suitability class in the three land units for irrigated paddy rice is classified as S2nr (quite suitability in accordance with the limiting factors for nutrient retention including: base saturation, pH, and C-organic). The average productivity in land units I is 5.1 ton/ha, land unit II is 4.5 ton/ha, and in land units III 5.26 ton/ha.
