The following three criteria: Required--End-of-life processing requirements (currently 4.6.2.1); Optional--Manufacturer recyclers or reuses toner material collected through its cartridge and container take-back program (currently 4.9.3.2); and Optional--Manufacturer recyclers or reuses plastics collected through its cartridge and container take-back program (currently 4.9.3.3) are revised in this...
Industrial ecology seeks options to lessen the environmental impact of industrial systems, through reducing natural resource use and waste generation, and by emulating the cycles that are utilized in ecosystems and nature. Design facets of energy selection and energy efficiency, which are key parts of Design for Environment and thus important considerations in industrial ecology, are described. The...
Electricity system in Indonesia is still dominated by coal and this trend will remain to meet its electricity demand in the future. However, many of the power plants have been operating more than fifteen years. As means to cope with instability of power supply and reduce environmental issues, the Government of Indonesia is considering the upgrading and modernization of the existing coal power plants...
In this work, the principal aim is establishing networks parameters of wireless sensor. These devices can transmit variables to monitoring the quality of tourist beaches in the Colombian Caribbean. We propose a methodology to choose the network elements and its technologies. We analysis data based on coverage and implement the prototype. We show that the maximum distance between nodes is 33 m at mesh...
PLTG Gilimanuk is a gas power plant in Bali consisting of 1 unit with total capacity of 133,8 MW. One of the challenge of PLTG is the large greenhouse gas (GHG) emissions that are donated to global warming. The study aimed to analyze the impact of the innovation program in reducing air pollutants to reduce the greenhouse gas effect generated by unit 1, Gilimanuk PLTG. An innovation program that have...
Rejuvenation and updating of a power generation technology is to make it more efficient, more reliable, and more environmentally friendly. Those conditions encourage the rejuvenation of Pesanggaran Bali power plant. Currently the power plant uses a diesel engine which emit a 978,448 ton of CO2 annually. The plan is to replace the diesel engine with gas engine with capacity of200 MW to generate electricity...
The monitoring, control or adjustment of dynamic environmental change is becoming a high priority within systems requiring constant twenty four hour observation such as server rooms, warehouses, greenhouses, utility stations and bio-systems to name a few and all of which may require dynamic supervision of humidity, temperature, gas levels, air-flow, barometric, ambience, intruder detection, the list...
The article is devoted to the problem of making environmental management decisions that take into account the interests of the enterprise in the form of profit and the interests of society and the state, by reducing damage to the environment. The authors pay attention to the process of making environmental management decisions. Proposed algorithm for making environmental management decisions is presented...
This paper presents a method to evaluate the reliability and environmental benefits of energy storage systems (ESSs) applied in firming up grid connected wind farms. Due to the variability and uncertainty of wind energy, ESSs have the potential to play a significant role in firming up the output power of wind farms. In this context, determining the size of ESSs in terms of rated power and energy is...
More and more people are using mobile phones for sensing and supporting their daily lives. With some signal and digital processing methods, every mobile phone could be used for sensing different activities or behaviors that people do every day. Increasingly, wireless sensor networks (WSNs) are being integrated with Mobile Phone Sensing (MPS) and this trend will be seen mainly in urban environments...
The purpose of this paper is to construct an online learning support in the context of the blinded learning. The learning support includes three parts: environment support, resource support and emotional support. The characteristics and functionality of the each part are presented. According to the characteristics of blended learning, the function of each module is designed from the three stages of...
The exploitation of distributed energy resources and problems associated with islanded energy grids are important in optimizing sustainability of electricity supply, where microgrids play a major role in the decentralized and dispersed production. As defined, a microgrid is a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a...
A purpose of this research is to investigate a difference of human cognitive behavior (in other word, ecological cognition) in VR using HMD and the real environment and to examine a method to compensate the difference. Therefore, this research conducts a comparative experiment using a cognitive behavior called “Stepping-over” and “Passing-under”. First, a subject estimate whether the subject can step...
The environmental/economic dispatch (EED) problem aims to allocate power generation units to meet power demand and minimize both fuel cost and emission of gaseous pollutants simultaneously. In this paper we apply differential evolution (DE) to solve EED. Two parameters of DE, CR and F, have significant influence on its performance. We control the parameter values by four mechanisms. Performance of...
An algorithm for controlling and quasi-optimal channel selection is proposed for the operative exchange of crisis environmental monitoring data. The radio network of data transmission is shown using a mobile command post that is equipped with the equipment providing: HF and VHF communication using repeater, radio relay, cellular, satellite communication, as well as WI-FI radio access.
Packaging currently used in the market often results in a waste of resources and environmental pollution. The implementation of green packaging can reduce pollution, optimize the environment, improve international competitiveness, promote the development of export trade, and is also conducive to the implementation of sustainable development strategies. However, despite the existence and benefits of...
Health, Safety, Environment and Ergonomie (HSEE) are important factors in any organization. An organization always have to assess its compliance in these factors to the required benchmarks and take proactive actions to improve them if required. In this paper, we propose a Fuzzy Cognitive Map-Bayesian network (BN) model in order to assist organizations in doing this process. Fuzzy Cognitive Map (FCM)...
Domain-specific languages are a means of speeding up and easing software system development. Agent-based simulations are simulation systems in which autonomous entities, namely agents, are developed in order to reproduce, analyze, or predict a phenomenon under study. Despite its potential, available alternatives for agent-based modeling and simulation benefit from recurrent domain-related concepts,...
The NeXOS project — Next Generation Ocean Sensors — aims to improve the temporal and spatial coverage, resolution and quality of marine observations through the development of cost-efficient innovative and interoperable in-situ sensors deployable from multiple platforms, and Web Services for key domains and applications. This typically involves innovation activities undertaken by scientists in cooperation...
