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 Ωm 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 Ωm and laterally and vertically is existed at 240-360 m and 45-94 m, respectively.

Abstract

Kemampuan pemecahan masalah dan kemampuan spasial memiliki peran yang sangat penting dalam pembelajaran matematika. Tujuan dari penelitian yaitu untuk mendeskripsikan kemampuan pemecahan masalah siswa dalam menyelesaikan soal geometri  transformasi berbasis high order thinking ditinjau dari kemampuan spasial. Penelitian ini termasuk penelitian kualitatif dengan metode studi kasus. Instrumen dalam penelitian, yaitu tes kemampuan spasial, tes kemampuan pemecahan masalah berbasis HOTS, dan pedoman wawancara. Analisis data penelitian ini yaitu analisis pemecahan masalah yang berorientasi HOTS dan analisis wawancara. Hasil penelitian ini menunjukkan siswa dengan kemampuan spasial tinggi mampu melalui tahapan pemecahan masalah dengan level kognitif menganalisis, mengevaluasi, dan mencipta. Siswa dengan kemampuan spasial sedang mampu melalui tahapan pemecahan masalah dengan level kognitif menganalisis dan mengevaluasi serta belum mampu melaksanakan penyelesaian dengan baik dan menemukan gagasannya dalam  memecahkan permasalahan. Siswa dengan kemampuan spasial rendah  hanya mencapai tahap level kognitif menganalisis, dan pada level kognitif mengevaluasi, hanya mampu memahami permasalahan tanpa memberikan penyelesaian. Hal ini menunjukkan kemampuan spasial tinggi lebih baik dalam menyelesaikan soal geometri transformasi berbasis high order thinking.

Abstract

The purpose of this study was (a) analyze the factors that affect the internal and external PD Tohaga market in the development of market management in Bogor, (b) formulate a development strategy selection market management, and (c) to establish priority in the development strategy of market management.The results, it is known under the total customer perceives PD Pasar Tohaga performance in managing the market is still low, while a high level of customer expectations. Strategis factors which became a major force and has the highest relative importance is the equity of local government through the budget and the availability of assets in the form of 24 traditional markets are ready to be developed. The main drawback strategic factor and has the highest relative importance is the large number of residents of Bogor Regency. Strategic factor threats that have the highest relative importance is the implementation of quality standards are difficult to meet in the retail traditional markets.
