ALTERNATIVE ENERGY SOURCES FOR INCREASING ENERGY EFFICIENCY OF IRRIGATION SYSTEMS
Authors: Dekhtiar O. O. 
Published: February 2020

Actuality of the problem. The article discusses the current level of use of alternative sources of electrical power in the world. The main areas of the global power development were determined, the statistical data of leading energy companies, analytical international organizations and financial institutions were analysed. For today, all civilized countries successfully switch to alternative energy sources: wind, solar energy, biofuels, etc. In addition, the use of solar energy is one of the most promising inexhaustible, renewable energy sources. The use of renewable energy sources replaces the traditional one, based on extractive technologies polluting the atmosphere with harmful emissions, and enhances the greenhouse effect, reduces the burden on the resource base and energy systems of countries and improves the environment. Sustainable development of the agricultural sector of the economy of Ukraine and, in particular, irrigated agriculture requires a reduction in energy dependence. In the structure of the cost of irrigation water, a significant share accounts for electrical power. That is why to increase the efficiency of irrigated agriculture, to ensure high and sustainable yields in the context of climate change, it is extremely important to reduce the cost of power consumption. The need to use alternative energy sources in the drainage complex of Ukraine as part of the implementation of the energy strategy of Ukraine, aimed at the transition to fficient use and consumption of energy resources is highlighted. The Institute of Water Problems and Land Reclamation deals with the investigations of measures and technologies to improve power efficiency to reduce the specific energy consumption for pumping water by pumping stations and to reduce the rate of power losses for water intake and water transportation by water supply paths. One of the effective measures to reduce power cost is the use of alternative energy sources, in particular solar energy. The economic potential of the measures for improving energy efficiency in irrigation systems wass estimated. Conclusions. The estimation showed that the use of modules of solar power plants installed above the surface of open irrigation canals will lead to lower energy costs in the face of a constant increase in tariffs, that is, it will help to increase the economic efficiency of irrigation, reduce the share of water resources in national energy consumption and have a positive environmental effect. The sale of surplus power to the energy system at “green” tariffs can significantly reduce the payback period for the modernization of the engineering infrastructure of irrigation systems.

Authors: Meilufi Sa’adah 
Published: February 2020

Abstrak: Dalam kajian ini akan dipaparkan bagaimana pengolahan biologis dengan sistem attached growth dilakukan pada lumpur tinja. Model yang dilakukan dalam penelitian sebelumnya terdiri dari bak penyaringan, bak pengendapan sementara sebagai pengolahan pendahuluan dan reaktor biofilter aerobik aliran down flow. Proses operasional dilakukan dengan mengalirkan limbah tinja ke dalam tiga reaktor biofilter. Untuk mencari % removal BOD520, dilakukan variasi waktu detensi (td), variasi debit limbah yang masuk ke reaktor (Q), variasi beban organik (OL) dan variasi diameter media tempat pelekatan. Dari hasil penelitan sebelumnya diperoleh bahwa pada td = 2 jam efisiensi removal BOD520 mencapai nilai tertinggi (78,12%). Sementara itu pada variasi beban organik, efisiensi removal BOD520 tertinggi terjadi pada OL = 2,05 kg BOD/m3.hr (85,1%). Hasil lain menunjukkan bahwa efisiensi removal BOD520 tertinggi sering terjadi pada reaktor yang berisi media dengan diameter terkecil (1/2 inchi). Dengan formula Eckenfelder, diperoleh nilai koefisien biokinetika yakni koefisien karakteristik media (n) dan koefisien factor pengolahan (Ko’), masing-masing sebesar 0,0544 – 0,558 dan 0,118 – 0,686/menit.

Más que aprender a seleccionar un modelo pedagógico, nos compete aprender a producirlo
Authors: Tapiero Vásquez Elías 
Published: February 2020

La condición positivista de la formación profesional de los maestros se vuelve “imperceptible” en la investigación educativa y pedagógica por las propias instituciones formadoras de maestros, cuando estas establecen la práctica de una falsa autonomía (pseudoautonomía) centrada, como fin último, en la escogencia de modelos pedagógicos, y en la que poco o nada participan en la creación de dichos menú. Esto explica, en parte, por qué en el ejercicio profesional docente, profesores y docentes-directivos se identifican más como miembros de comunidades educativas, que como miembros activos de comunidades científicas, es decir, comunidades productoras de conocimiento en pedagogía y educación...

The production of dried tea leaves and tea consumption in Indonesia has increased from year to year. This condition was directly proportional to the spent tea leaves produced. Spent tea leaves contained 37% cellulose which can adsorb heavy metals in polluted water. Iron (II) metal was often found in high concentrations in ground water, so a treatment process was needed. This study aimed to analyze the removal of iron (II) in water by using activated spent tea leaves.The type of this research was true experiment with a pretest-posttest controlled group design. Spent tea leaves with size 80 mesh was activated with 0.1 N HCl for 36 hours. The method was carried out with a batch system in an artificial iron solution the initial concentration was 9.85 mg / L, with mass of adsorbent was 10 grams, pH = 7, stirring speed 100 rpm, contact time 15 minutes, 25 minutes, and 35 minutes. Measurement of iron levels was carried out before and after treatment using the SSA method. FTIR test carried out before and after activated spent tea leaves were used adsorption. Data analysis was carried out descriptively and analytically (One-way Anova Test and LSD Test).The results showed that activated spent tea leaves can remove iron (II) levels in water. The result of One-way Anova test and LSD test, the higgest removal of iron (II) occurred at 35 minutes contact time with adsorption efficiency was 90.36%. FTIR test results showed that activated spent tea leaves in this study contained functional groups were O-H, C-H, C=O, C=C, and C-N.This study concluded that activated spent tea leaves can remove iron (II) in water. The higgest removal of iron (II) occurred at 35 minutes contact time. Further research is needed to achieve 100% adsorption efficiency and find an effort to reduce turbidity in sample water after treatment. Keywords: Clean Water, Iron (II), Spent tea leaves
