Abstract

Yasar et al, 2017. Prediction of Ground Water Potential for Optimization of Rainfed Rice Field in Supporting Food Security. JLSO 6(2):170-175.In Simeulue Island, that has the existed paddy field and generally of that is  rainfed. Recently, to irrigate the paddy field with that percentage is expected enough by natural meet of the necessity of paddy field by receiving the potential precipitation. However, rising of the climate change has caused paddy field activity is not fully runned by only utilizing the precipitation and utilizing the surface water, as irrigatiom water resource is not possible because of geological difficulty. This article aims to find a breakthrough related to the problem of irrigation water insufficiency through utilization of natural resource potency in Simeuleu Island. Presenting is descriptively done using primary data by way of field measurement and literature review to obtain a beneficiary of groundwater as irrigation water resource. Data acquiring in this research uses geoelectrical method by setting the Wanner-Schlumberger configuration of Resistiviti meter ARES. Data were obtained from one spread that was east-west oriented by having 460 m spread length and 20 m spacing interval. The coordinate of spread is at initial point N 02°25?14.2?/E 96°18?12.2? and at final point N 02°25?43.9?/E 96°18?27.1. Based on the 2D resistivity cross section shows that Situbok village (STB) is generally obtained a low resistivity value which is 2-100 ?m in range and dominantly expected as alluvium. Low resistivity value can be estimated as a conductive layer (aquifer) which commonly consists of groundwater. On the cross section of resistivity value, the conductive layer is the layer which has the resistivity value less than 16 ?m and laterally and vertically is existed at 240-360 m and 45-94 m, respectively.

Abstract

The objective of this research was to study the effect of nutrient fertilization on the growth and development of nepenthes (Nepenthes mirabilis). The research was conducted from October 2011 until March 2012 at Sukarami village, Palembang, Indonesia. Factorial randomized block design with two treatment factors was applied. The first factor was NPK fertilizer dosage which consisted of three levels: Po = no fertilizer, P1 = 5 g, P2 = 10 g. The second factor was number of ants: S0 = none, S1 = 20, S2 = 40, S3 = 60. The results indicated that NPK fertilizer application of 5-10 g to the planting media could increase plant growth and development, particularly in plant height, stem girth, and leaf number of N. mirabilis. Giving 60 ants per plants into nepenthes pitcher could yield the largest pitcher number, 3-4 pitcher per plant. Combination of 5 g NPK and 20 ants, similarly, combination of 10 g NPK and 0 ants resulted in the largest leaf increment (10-11 leaves). Combination of 0 NPK and 60 ants resulted in the largest pitcher number (3-4 pitcher per plant).

Abstract

The demand of corn continues to increase along with the increasing of populations and industries. Compliance efforts could be done by increasing productivity through extensification and intensification farming. Statistical data showed that corn harvested area and production in South Sumatra over the period 2000-2012 was very volatile but had a tendency to increase since 2006. The area of ??land suitable for development of corn in South Sumatra, which amounted to 898,877 ha. This area consists of the intensification of land (205,709 ha), extensification of land (159,444 ha) and the diversification of land (533,724 ha). Land use for corn so far has been done in some districts/cities having dry land like Ogan Komering Ulu (OKU), OKU Timur, Ogan Ilir, Ogan Komering Ilir well as in several districts that have ups and downs like agro Banyuasin and Musi Banyuasin. South Sumatra AIAT demonstration plots showed that significant productivity of corn. In 2010, IPM demplot of Mulyasari village, sub district of Tanjung Lago, District of Banyuasin showed that productivity of Bima 4 (8.8 t/ha), Bima 5 (8.3 t/ha), and Bisi 2 (8.4 t/ha), whereas in 2011 Banyuurip demplot showed that productivity of Bima 3 (11.27 t/ha) and Sukmaraga (8.13 t/ha).
