Published: February 2019

One of the major obstacles in increasing the agricultural production yields is the inappropriate management of land use due to the differences of land biophysical characteristics in each region. Therefore, it is necessary to have spatial-based land use management that is appropriate in handling agricultural land. This research aims at structuring geospatial information of food land biophysical characteristics and food land appropriateness (potential and limiter) for food plants development in Pangkep Regency. This research uses the up-to-date approach of multi-scale observation, so the problems becoming the restricting factors of productivity can immediately be overcome. The method used consists of 2 stages, namely stage 1, analysis of food land (biophysical) climate and land characteristics through land survey, laboratory analysis, and land characteristic spatialization; stage 2, analysis of food land appropriateness (potential and limiter) using land appropriateness method of fuzzy set / FAO, satellite image information extraction, ground truth, and ground sampling. The results of the research are in the form of geospatial information of food land biophysical characteristics and food land appropriateness (potential and limiter) for food plants development in Pangkep Regency. With the information, decision makers will have more ease and they integrate in making policies for food land use management in Pangkep Regency that will end up aiming to increase food production.Â Keywords: geospatial information, food land, land biophysics, land appropriateness, management

Published: February 2019

The manufacturing of physical device of electrostatic precipitator (ESP) requires a costly budget. The risk of performance failure of an ESP device could be minimized by simulating an ESP using a finite element method program. The performance of the ESP model of parallel plate type using COMSOL Multiphysics program was simulated in this research. The ESP geometric model was drawn in 3D specifically, then it was integrated using laminar flow, electrostatic and particle tracing studies. Laminar flow and electrostatic studies are simulated simultaneously and the results are coupled by a study of particle tracing. The simulated test particle consists of two types: particles with physical features of 60 to 100 mesh and microparticles 0.5 to 1 μm. The result showed a good agreement between the simulations and the experiments. The size and type of particle are crucial to the successful performance of an ESP device. Keywords: electrostatic precipitator, COMSOL multiphysics, microparticle Pembuatan perangkat fisik electrostatic precipitator (ESP) membutuhkan biaya yang cukup mahal. Risiko kegagalan kinerja dari perangkat ESP dapat diminimalkan dengan cara membuat simulasinya menggunakan program berbasis finite element method. Pada penelitian ini disimulasikan kinerja model ESP jenis pelat paralel menggunakan program aplikasi COMSOL Multiphysics. Bentuk geometri model ESP digambar secara 3D berdasarkan ukuran yang spesifik, kemudian model diintegrasikan menggunakan studi laminar flow, elektrostatik dan particle tracing. Studi laminar flow dan elektrostatik dikalkulasi secara bersamaan dan hasilnya dikopel oleh studi particle tracing. Partikel yang disimulasikan terdiri dari dua jenis yaitu partikel dengan ciri-ciri fisik 60 sampai 100 mesh dan partikel mikro 0,5 sampai 1 µm. Hasilnya adalah terdapat kesesuaian antara simulasi dibandingkan dengan eksperimen. Ukuran dan jenis partikel sangat krusial terhadap keberhasilan kinerja perangkat ESP.

The wind power plant is one of the renewable energy source that can reduce the environmental and social impacts caused by fossil power plants. Furthermore, it requires protection systems, such as ground protection system for the safety of personnel and devices that use electricity as a power source from electric surges. In this paper, analysis of the 2.5 MW wind power plant grounding system design in Sidrap South Sulawesi is presented. The analysis was done using ETAP 16.0 software to determine the value of actual touch voltage, step voltage, and grounding resistance. The ETAP simulation results show that the value of actual touch voltage is 2162.8 V, step voltage is 726.2 V, and the grounding resistance is 0.8 W. The results indicate that wind power plant grounding systems are able to keep humans and devices around the power plant safe.Pembangkit listrik tenaga bayu (PLTB) merupakan suatu pembangkit energi terbarukan yang dapat mengurangi dampak lingkungan dan sosial yang ditimbulkan oleh pembangkit listrik tenaga fosil. PLTB membutuhkan sistem proteksi pentanahan yang merupakan suatu proteksi terhadap keselamatan personel dan perangkat yang menggunakan listrik sebagai sumber tenaga dari lonjakan listrik. Pada tulisan ini dipaparkan hasil analisis terhadap rancangan sistem pentanahan pada PLTB 2,5 MW di Sidrap Sulawesi Selatan. Analisis dilakukan dengan bantuan software ETAP 16.0 untuk menentukan nilai tegangan sentuh aktual, tegangan langkah, dan tahanan pentanahan. Dari hasil simulasi ETAP diperoleh nilai tegangan sentuh aktual sebesar 2162,8 V dan tegangan langkah sebesar 726,2 V, dan tahanan pentanahan sebesar 0,8 W. Hasil ini menunjukan bahwa sistem pentanahan PLTB dapat melindungi personel dan peralatan di sekitarnya.

Métodos de razonamiento lógico-jurí­dico aplicados a decisiones judiciales: la jurisprudencia como mecanismo de poder estatal
Authors: Figuera Vargas Sorily Carolina , Cedeño Dávila Camila Bernarda , Camacho Balseca Maxwell Andrés Andrés 
Published: February 2019

Este estudio1 analiza como la dialéctica brinda métodos que colocan al juez en una posición singular dentro de la estructura de poder del sistema democrático del Estado. En las siguientes páginas, inicialmente, al contraponer dos métodos clásicos como lo son el deductivo y el inductivo, se podrá determinar si de hecho su aparente contradicción según el proceso de razonamiento que persiguen, genera una incompatibilidad para trabajar de manera conjunta, y así­ obtener mejores resultados al momento de tomar una decisión de carácter judicial. En tal contexto, se estudiará la lógica jurí­dica y su manifestación como una herramienta esencial del conceptualismo aplicado a la doctrina positiva del derecho, pues basa su accionar en cuestiones prácticas donde el concepto surge de una realidad inherente. Este escrito, en definitiva, busca exponer el uso de la lógica jurí­dica en la ciencia del derecho y, como bajo principios básicos el razonamiento, hace una función relevante para crear un conocimiento y aplicación de esta disciplina más correcta e informada, además al ser adaptada a las necesidades reales de la sociedad.
