Published: June 2019

Abstract
Discharge data is one of the important data in evaluating the reliability of water resources management in the watershed. Most watersheds in Indonesia do not have observed discharge data over a long period. While the availability of rainfall data is almost available in all watersheds with a much longer period. Therefore, it is necessary to convert rain into a runoff to obtain a discharge event with a long period. Rain-runoff transformation is a very complex process. Rain input contains the variability of space, time and uncertainty. A very complex hydrological analysis is needed to find out various parameters related to rain models for a runoff. One of the hydrological models that can be used is HEC-HMS 4.2. This paper aims to analyze the relationship of rainfall - runoff in the Garang watershed using HEC-HMS 4.2. For calibration, observational discharge data is used from AWLR Kreo. Based on optimization analysis, the hydrological parameter are obtained CN composite 66.4, groundwater content 128.48 mm, Initial Abstraction 25.7 mm and imperviousness 9.27%. The validity of the model is quite satisfactory, judging from the correlation values, RMSE and Nash.

Published: June 2019

AbstractThe effort in improving water quality of fishponds could be conducted with various methods, including the integration of mangrove trees known as silvofishery. However, an additional method could be applied by deploying compost. This research aimed to study the distribution of phytoplankton community in the silvofishery pond and to analyze the impact of compost application in the silvofishery pond planted with different mangrove species. The research was conducted in September 2017. Three silvofishery ponds planted with mangrove speciesAvicennia marina, Rhizophora mucronataand mixed of both and one control pond were utilized. Compost was deployed in the silvofishery pond as much as 2 kg for 25 m2 area. The sampling of phytoplankton was conducted one week after the compost deployment. Data analysis was conducted for diversity index, while statistical analysis was conducted by chi-square. The result showed that the deployment of compost could slightly improve water quality. There were only five phytoplankton species with total density of 85 ind.l−1in the control pond, while ponds withA. marina, R. mucronataand mixed of mangrove consisted of 7 species (155 ind.l−1), 7 species (119 ind.l−1) and 5 species (103 ind.l−1) respectively. Diversity index showed medium values (1.56-1.95) with high evenness values (0.97 – 1.0). Chi-square analysis showed that each treatment has a significantly different composition of phytoplankton.

Authors: Shin Won Dong , Park Jaejun , Park Hae-Won 
Published: June 2019

Abstract
This paper introduces a new multi-modal robot capable of terrestrial and aerial locomotion, aiming to operate in a wider range of environments. The robot was built to achieve two locomotion modes of walking and gliding while preventing one modality hindering the other. To achieve this goal, we found the solution from Pteromyini, commonly known as the flying squirrel. Pteromyini utilizes its flexible membrane to glide in the air, and it shows agile movements on the ground. We studied Pteromyini to mimic the key features that allow Pteromyini to perform aerial and terrestrial locomotion. We adopted the flexible membrane and gliding strategy of Pteromyini to the robot. Through dynamics analysis and simulations, the overall design was determined. The flexibility of the membrane was also chosen considering the robot’s performance in the air and on the ground. The leg was optimized to perform with regulated motor torques in both walking and gliding. From gliding tests, the robot showed an average gliding ratio of 1.88. Inspired by Pteromyini, controlling the robot’s angle of attack with leg and tail movement was also adopted and tested. Different gait patterns and changing walking directions were tested to demonstrate the robot’s terrestrial performance. The average walking speed was 13.38 cm s−1. The experimental results demonstrated the robot’s functionality in aerial and terrestrial locomotion.

Published: June 2019

Abstract
The organization of production is based on technological preparation processes and subsequent tests for certification of a new product line. The existing methodology for organizing production is based on the basic structures of production technologies that include heterogeneous technological systems with a control superstructure and pronounced standard group elements that make up the integrity of any technology: personnel, equipment, materials and processes. Changing the standard element will change the state of the technological system; therefore, the introduction of the SMED methodology for the technological preparation processes of organizing new production or the optimization of existing production cycles will lead to a reduction in typical losses and a decrease in production cycle costs.

A cooperative game in Asian international electric power integration
Authors: Minarchenko Ilya 
Published: June 2019

Abstract
The paper examines effects of long-term international integration in the field of electric power industry. An advantage of integration is provoked by the fact that the cost of introducing new generation capacities significantly exceeds the cost of new power lines and transmission of the energy from existing power station of another country. When countries form a coalition, the problem is to allocate the coalition’s surplus over its participants. It can be solved by notions of cooperative game theory. The present investigation is based on the real data on six countries of the Northeast Asian region: Russia, Mongolia, China, North Korea, South Korea and Japan. Electric power system is described by the ORIRES model. This model optimizes power generation, power flows, and the development of generation capacities and power lines of the system. We formulate corresponding cooperative game in characteristic function form, and specify the Core and the Shapley value. Effects of international integration are discussed.

Published: June 2019

Abstract
In this paper, we analyzed the thermo-physical properties of landfill gas, which can be used in the system of communal services of the city from specialized landfills for collecting municipal solid waste. Authors do not yet consider ways of delivering this type of fuel to subscribers, but imply as an option of possible technologies that there is a storage facility and an industrial factory for cleaning and condensation landfill gas for further use in the communal system of the city. There are Graphs of changes in various indicators of landfill gas in this article. This study can be used to predict energy conservation not only of large cities, but also of small settlements from the use of an alternative energy source - landfill gas. Its main characteristic (in terms of thermal physics) is the lower calorific value of the fuel. It depends on the composition and moisture of the gas. The report discusses the methodology for studying the lower calorific value of landfill gas, based on the chemical balance of this fuel. Another important characteristic is the environmental effect. Reducing emissions of landfill gas decrease the greenhouse effect, which has a negative impact on the Earth’s atmosphere, biosphere and hydrosphere. It could be provided for the production of electrical energy, as well as a combination of electric and thermal. There is the possibility of producing hydrogen for a fuel cell. However, this requires independent economic, environmental and energy comparison of various technologies for using of landfill gas in the engineering infrastructure of the city, as well as different methods of transporting and producing energy-efficient condensate compressed landfill gas (the best option when the methane content in this fuel is like natural gas).

Published: June 2019

Abstract
The authors propose a model of fuzzy inference system (FIS) to determine the optimal consumption of hydro resources of hydroelectric reservoirs by the criterion of maximum generation of electrical energy. It is proposed to use a fuzzy controller that allows to develop optimal strategies to ensure the maximum energy output of hydroelectric power stations and passes to the downstream, to formulate proposals for creating a subsystem for calculating the regimes, schedules of drawdown and filling of reservoirs by the criterion of maximum generation of electrical energy. The use of fuzzy controllers and submission to their inputs of data on changes in the regimes of a cascade of hydroelectric stations in real time allows us to obtain a FIS system that will be an assistant for the operational management of hydroelectric reservoirs.
