The Effect of Population Growth and Economic Factor to Conversion Function of Agricultural Land Supply Chain in North Aceh District
Population growth and economic factors are the causes of changes agricultural land supply chain use in North Aceh District. The regional development requires land for housing, industry, trade and other purposes while land availability was constant, resulting in land conversion from the function of agricultural land supply chain to non-agricultural. The shifting of land use from 2012 to 2015 was significant in the reduced farm forestry 7,138 ha, agricultural estate 6,465 ha and Wetland area of 227 ha. The purpose of this study was to determine the significance of the effect of population growth and economic factors on the conversion of agricultural land supply chain into non-agricultural land supply chain. The method used was Quantitative Method by using Structural Equation Model (SEM). The results showed that population growth and economic factors affect the conversion of land from agricultural land supply chain to non-agricultural land supply chain, especially in urban areas. The shift in the dominant production area for housing, store shops because it is more profitable as a place of business in increasing people's income but this causes the reduction of agricultural land supply chain as a support food suppor
Operation Planning Reservoir with Linear Programming Optimization Model for Water Demand of the Community In Aceh Besar District
On the condition before building a dam, Aceh Besar district often a shortage of water for the needs of the community, so that people difficulty in doing their activities. There is a river in the Aceh Besar district named “Keuliling River”. The river is one of the watershed sub-basins of Krueng Aceh which has large enough potential of water to increase the supply of raw water in order to meet the water needs of the Banda Aceh City and Aceh Besar district.Therefore, a reservoir building was built that able to acomodate a large capacity of water. The resorvoir was named “Keuliling Reservoir”. “Reservoir Keuliling” has 38.20 km2 watershed areas, 259.94 hectares wide puddle on Normal Water Front (MAN), a total of 18,359,078 m3 bin normal water level at an elevation of 45.80 m and has an effective pitcher of 12.99,208 m3. The reservoir also serves as a provider of raw water for the development of inland fisheries, livestock, rice fields and others. The greatest needs are to be served by the reservoir is water requirement for paddy planting season Rendeng in October to December and the gadu growing season from April to June. To meet all these requirements then performed the planning operation of reservoir. Ie, by optimizing the volume of water storage at the end of the month through the optimization of the use of inflow data and outflow data. The optimization performed with optimization models Linear Programming. The results of the optimization is the volume of water in reservoirs that have large water needs, which in October is 13,380,986 m3, in November is 76,640,036 m3 and in December is 38,104,116 m3. Where in each month of the above conditions are still effective volume reservoirs at 12,992,080 m3. The results showed that from month to month never happened reservoir conditions at the level of the dead reservoirs, this illustrates that Keuliling reservoir can meet the water needs of the community
A Channel Drainage Slope Modified as Discharge Supply Chain in the Coastal Area
Slope in the drainage channel system is a primary factor that determines the quantity of water to be gravity discharged. By having bigger slope, the flow velocity becomes larger and the capacity of water discharged becomes more so that there will be no surface runoff. Lhokseumawe is a city located in the coastal area with its height is only 0.95 m above sea level. It is difficult to build the appropriate slope of the channel. For this reason, innovation is needed by modifying the slope of the channel in stages and tiered at each distance of 50 m, by which for channels along the 1,350 m will have 27 stages. The discharge capacity required to flow the rainfall is based on a 2-year return period of 5.10 m3/ sec. Slopes under normal conditions are 0.0013 to get a flow velocity of 1.27 m/sec. Using a section area of 1.32 m2 channel it can get discharge capacity of 1.67 m3/ sec. Furthermore, the slope of the channel was modified to 0.005 at each distance of 50 m and this obtained a flow velocity of 2.46 m/sec so that it was able to drain a discharge capacity of 3.24 m3/ sec. By modifying this channel slope can increase the discharge by 1.57 m3/sec or 93.7% compared to the slope without modified. It has not been able to multiply the overall discharge but at least can reduce the discharge 93.7%
