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

Soybean is a potential type of legume plant to be developed in Andoolo District, South Konawe Regency. However, the soybeans production is still relatively low. The main problem in the low production of soybeans is the unavailability of information on soil fertility status, especially the status of organic C-nutrients, P and K. Therefore information on soil nutrient status is very necessary. The study was conducted in the village of Ataku, Andoolo District, South Konawe Regency in May to July 2018 using the Dry Soil Test Equipment (PUTK) method. There were 27 soil samples taken randomly to obtain soil nutrient status including organic matter, P, K and soil pH and recommendations for soybean fertilizer dosages in the Andoolo District. The results of this study showed that C-Organic status, P, K and pH in Andoolo District varied. Based on the results of the analysis, the recommended fertilizer dosage in Andoolo District is giving 2 tons/ha of organic matter plus 200 kg/ha of Urea fertilizer, 200 kg/ha of SP36, and 100 kg/ha of KCl for low K status, 75 kg/ha of KCl for moderate K status and 50 kg/ha of KCl for soil with high K status. For soil with a very acidic and acidic pH status, it is recommended to give 500 kg/ha of lime doses to increase the soil pH to neutral conditions.

The large population growth of Indonesia encourages the transition of the function of agricultural land into non-agricultural land. The demand for land from time to time always increased, while the available land limited in number. This caused the conversion of agricultural land into non-agricultural land. This phenomenon certainly could bring serious problems. This study aimed to determine the land productivity index for rice and green beans cultivation and to find out the factors that influence production. The productivity indexes analyzed based on the Storie Approach. Soil sampling was carried out by an open grid method divided based on five land map units which spread across three different villages in Kampili irrigation area. The results of the study indicate that the highest productivity index is shown in SPT 5 where the productivity index is 47 and the lowest productivity index is shown in SPT 2 where the productivity index is 21,6. The land productivity index in the downstream of the Kampili irrigation area, which is located in the district of West Bajeng is poor to sufficient level. The low value of land productivity was strongly influenced due to poor soil quality, especially soil chemical properties. The results of the laboratory analysis show that nutrients in those areas are low.

The extend remobilization of nutrient on crops so far is known well. However, as we assumed that the re-translocation of the particular nutrient as nitrogen has a strong affect to the terpenoid metabolic like citronellol. In many cases, the environment stress such as drought induced volatile compound as citronellol leave in citrus. The aim of experiment is to observe the distribution of citronellol as consequence the distribution of nitrogen on different layer of tree canopy. The method of the research obtain the samples of leaves which were collected from different layer of citrus canopy from 10 samples of trees on each part of field: bottom layer, middle layer and upper layer of canopy. The randomized leaves were collected and analyzed by the HPLC and Spectro-photometer to measure the content of nitrogen and glutamate distribution correlated to citronellol content. The results presents that the closely correlation of distribution of nitrogen between bottom layer, middle layer and upper layer of lemon leaves to produce glutamate and citronellol. The remobilization of nitrogen from bottom leaves content 1.35 ppm followed by middle leaves 1.4 ppm and the highest is the upper leaves is 1.65 ppm. As consequence that the glutamate and citronellol were increase as the same trend as those nutrients distribution. The glutamate seems to be the precursor of the secondary metabolic which was converted into the harvested leaves of citrus. Increasing of 5% glutamate from the upper leaves to the middle leave and the bottom leaves seem to be much accumulated of citronellol content in the bottom leaves.

Various ways have been made to increase the productivity of rice plants as a source of staple food of Indonesian society. One ofthem is the addition of nutrients in the soil (fertilization). Currently, the innovation use of seaweed as fertilizer is widely used in several countries in the world, because seaweed contains phosphorus, potassium, and some other micro elements. This study aimed to analyze the use of various types of waste seaweed to improve the productivity of paddy rice on the ground Vertisol. The study lasted from December 2014 through Sept. 2015, at Greenhouse, Teaching Farm, Faculty of Agriculture, University of Hasanuddin Makassar. The research method is a randomized block design consisting of eight treatments and six replications (48 pot experiment). Each treatment is C0 (control), C1 (fertilizer N 300 kg / ha, P 100 kg / ha and K 100 kg / ha), G1 (Gracilaria 10 g / pot), G2 (Gracilaria 100 g / pot), S1 (Sargassum 10 g / pot), S2 (Sargassum 100 g / pot), K1 (Kappaphycus 10 g / pot), and K2 (Kappaphycus 100 g / pot). The addition of Sargassum seaweed fertilizer waste 100 g / pot and Kappaphycus dose of 100 g / pot can increase K-dd, Na- dd, base saturation, increase the value of N, P, K, and Ca-dd, but administration with concentrations of 100 g / no maximum pot for rice crop production by causing toxicity in plants. The addition of seaweed fertilizer waste treatment Gracilaria 100 g / pot is effective in improving Vertisol soil chemical properties and can provide maximum results for the productivity of rice plants

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.
