The green open space is one of an effort in order to handling of the increasing the greenhouse gas emission, because green open space has an ability to absorbing the CO2 emission. The purpose of this research is to find out the potential of absorption capacity of CO2 by the public's green open space and to analyze the level of absorption of CO2 by green open space from transportation activity. The method in this research is calculate the value of CO2 emissions and counting the trees which has diameters more than 20 centimeter. The sufficiency of green open space was analyze and then compared the absorbing power of CO2 by trees with number of CO2 emissions that produced. Tampan district is produced the CO2 emissions from transportation which is high enough as much as 2.102.614.367 kilograms CO2/year. While the ability of CO2 absorption by the public's green open space in Tampan district only 7.979.245,86 kilograms CO2/year. The result of analysis show that the public's green open space in Tampan district that viewed from absorbing CO2 emissions of transportation is still not enough with percentage is only about 0,38%.

Background: Integrating sustainability development' aspects in the design process is becoming, a growth area in companies. Consequently, sustainable product design has to consider the different aspects of sustainability throughout its life cycle phases in addition of other requirements. This integration is becoming more complicated due the difficulty of managing the constraints and alternatives related to the product and stakeholders needs. This study aims to highlights the most used Multi-Criteria Decision Making (MCDM) tools and methods used in sustainable product design process. Contribution: Product design process involves interesting decisional tasks such as the choice of materials, standard parts, technical solutions. Hence, the contribution of this work is to help designer to adopt relevant MCDM tools and methods that can be integrated to other tools to facilitate and to justify their decisional tasks. Method: Several methods have been affected to solve the problems related to this complexity such as MCDM. A literature review was conducted based on Siencedirect and GoogleScholar articles databases. After filtering more than 200 articles only 62 articles were considered to analyze the correlation between sustainable product design and MCDM. Results: Classified MCDM use according to the type of choices to achieve SPD goals. This paper allowed us to find matches between MCDM methods and SPD problem. The majority of case studies result show that a large portion of sustainable design methods, techniques, and tools are applied to the sustainable product' along its different life cycle phases Conclusion: It is noticed that the use of MCDM methods are an important outcome in the sustainable product design process and deeply helps designers to make suitable choices. Also, several matches relating MCDM, other methods and sustainable product design sphere are discussed

The objectives of this research are (1) to analyze the changing patterns of soil quality, water quality and Methane (CH4) due to cropping index improvement, (2) to analyze productivity and economic due to the increasing of rice cultivation intensity at technical irrigated rice field, (3) to arrange the optimum model of intensive rice cultivation at technical irrigated rice field by Integrated Crop Management (ICM) approach with low methane emission sustainably, and (4) to analyze sustainable index of optimum model of intensive rice cultivation with cropping index improvement at technical irrigated rice field and (5) to arrange the policy strategy in the implementation of optimum model of intensive rice cultivation at technical irrigated rice field by Integrated Crop Management (ICM) with low methane emission sustainably. This research used split plot design. The treatment of irrigation systems as the main split plot factor is intermittent irrigation and continuous system (flooded) and fertilization as sub plot factor which is fertilization treatment are applied, based on the Recommendation of the Minister of Agriculture No. 40/2007 and based on laboratory analysis recommendation with 8 levels of fertilization treatment with 3 replications. Data analysis for soil quality, water, methane emissions, production and rice productivity are done by analysis of variance (ANOVA) and for the analysis of production, productivity and the methane emission are continued into Duncan Multiple Range Test (DMRT) test. Further sustainability analysis of the RAPFISH modification is called Rapfarm (Rapid Appraisal for Farming) by using the multidimensional scaling (MDS) method, to arrange the scenario is used dynamic model systems approach. The result of study showed that intensive rice cultivation by increasing of planting intensity did not reduce soil and water quality and methane emission can be pushed until 66,05%. Cultivation of intensive rice by increasing of planting season up to four planting seasons in a year by ICM approach can increase rice production and productivity up to 30% and also increase farmer’s income significantly. Optimum Model of intensive rice cultivation is by planting rice for four times a year with the planting pattern of rice-rice-rice-rice by using ICM system especially by using intermittent irrigation system and fertilization appropriate for plant nutrients (recommendation from result of laboratory analysis with the dosage 100% plus probiotic). The value of methane with optimum model application can be reduced significantly from 218.826.889,43 kg CH4 to 397.181,03 kg CH4 in 2030. The value of sustainable index of optimum model of intensive rice cultivation has range between 42,84-66,54 (included in the category of sufficiency) and the result of statistical test showed that RAP-INLASIT-IP 400 method is good enough to be used as one of the devices to evaluate the sustainability implementation optimum model of intensive rice cultivation on technical irrigated rice field. 098106004

Climate change vulnerability is the function of exposure, sensitivity, and adaptive capacity of its natural and socioeconomic systems. Following spatial “scale” of the assessment, administrative-territorial units were selected for this study. A field survey questionnaire was used to collect data for the study based on the sample size of 500 questionnaires that was administered to household heads in the study area. In the questionnaire, questions were designed to give respondents the opportunity to choose from several alternatives given in the instrument while descriptive statistics was for the analysis of data. Descriptive statistics analysis based on mean ranking was carried out to identify the level of peoples' vulnerability to climate change in the study area. The exposure assessment was based on the response analysis of baseline information. The sensitivity assessment for the study was analyzed by using physiographical and socioeconomic characteristics, described by a set of specific indicators and responses of the residents. The adaptive capacity was captured by general economic and agricultural indicators, taking into consideration the major occupation the predominant lifestyle of the residents. Through a ranking approach, the relative vulnerability of each ATU was calculated by summing its sensitivity and adaptive capacity ranks; the latter were obtained as combinations of their primary indicator ranks, arranged in an increasing and decreasing order, respectively. The major climate change exposure pathway in the study area were reduction in green environment, decrease in total annual rainfall, warmer weather, early cessation of rainfall, late on-set of rainfall and shrinkage of water bodies. The major sensitivity to climate change was decrease in crop yield, whereas increase in cost of food crops, drought incidents, famine, poverty, indiscriminate falling down of trees and disaster. It was also established that the major adaptive strategies to climate change in the study area were irrigation farming, use of organic manure, planting of drought tolerant varieties and early planting.

Sustainability is an issue that is increasingly attached to the planning and design of the built environment. One issue is the sustainability of the traffic jamming. Problems of traffic jamming has become a natural thing happening in developing cities in Indonesia. Traffic jamming problems gave many negative impacts both directly and indirectly. Paradigm major cities in the world about tackling the problems of traffic jamming through the application of concepts that promote integration between land use with transportation. One concept that is applied in major cities in the world are TOD. Transit Oriented Development or TOD is a concept in an area centralized on modes of transport where the area has a comfortable distance to walk and able to perform daily activities therein without the need to use personal vehicle (automobile). Binjai as TOD development sites, is one part of the metropolitan area Mebidangro, growing city. Locations case of this design lies in the area of 1 km radius of the Binjai train station. Binjai has a station route from Medan to Aceh who stopped in its tracks until Binjai. By reviving this route to Aceh potential to make Binjai as a transit region or midpoint for opportunities of business transactions between Aceh with Medan. With the selection of the hotel and retail building functions referred to as containers / resting place during transit, to meet business partners, and conduct business transactions. The building design using functionalism architecture themes with the objectives to be achieved in sustainability and TOD, the selection of this theme intends to translate the functions that will be implemented into the design follows the functional characteristic and is expected to express / explore the design basis more depth. 110406099

We substantiated design and construction-technological solutions for increasing the energy efficiency of thermomodernizable buildings and structures based on the conducted calculation-and-experimental and numerical studies. We investigated effective structural parameters and material of examined elements of a thermomodernization system of residential buildings and structures, which started their operation before the 90-ies of the last century. We proposed a number of innovative design and construction-technological solutions for the thermomodernization of residential buildings and structures that provide simultaneous modernization of a system of central water heating and facade insulation. Distribution of the temperature field inside a building structure, temperature on the surface of a facade thermal insulation at variation of its thickness by different forms of making of new indents, where new pipelines of a two-pipe system of a central water heating are located, were investigated. In particular, we established that such placement of pipelines makes it possible to reduce heat losses from these pipelines significantly (by up to 74 %) comparing with the placement in a layer of facade insulation at the side of a wall. We investigated the dependence of the cooling time of a heat-transfer agent temperature to 0 oC at the complete cessation of its flow through pipelines on the thickness of a thermal insulation. We determined experimentally the minimum thickness of a facade insulation layer, which is 50 mm, for the studied temperature mode and operating conditions, as well as for characteristics of the materials used, the geometry of pipelines and the facade insulation.We obtained the optimum thickness of a facade insulation layer, which is 100 mm. It provides up to a 100 % freeze protection of pipelines even when a heat-transfer agent movement stops for more than 24 hours. We established that an increase in the thickness of a facade heat insulation contributes to the additional drainage of a building structure, which leads to improvement of thermal characteristics of the thermomodernized building. The study showed that the developed innovative design and construction-technological solutions lead to a significant reduction in the energy consumption of existing buildings and structures of the housing stock, which has been in operation for longer than 30 years, and contribute to maintaining comfortable living conditions.

According to historical climatology, climate and climate change have always had an impact on human society. Anthropological climate change is happening Fast and will indisputably affect the global economy for decades to come. This paper provides a review of the expectations of leading economists and organisations on the magnitude of this effect. It clarifies the different approaches used to quantify the future economic loss attributed to climate change. Despite the different approaches used, all the authors examined in the paper foresee a negative impact of the climate change on the global economy. The different approaches result in different predictions about the magnitude of the impact. The authors express similar positions about the geography of the damages that will be caused by the climate change. The most affected countries will be most likely those in Sub-Saharan Africa and South Asia. A moral paradox arises that the least developed countries that are not at fault for anthropogenic climate change will have to carry the economic burden of its consequences. The paper also suggests and compares a variety of measures that could be taken in order to adopt to and mitigate the negative impacts of climate change on the economies.

The object of research is the methodology of existing models of climate change and the identification of areas that are suitable for agricultural production. The consequences of natural disasters (floods, tornadoes, tornadoes, earthquakes, volcanic eruptions etc.) are the destruction of local ecosystems and the local economy, the emergence of threats to food and water supply, the creation of social conflicts, internal and external migration. Damage from natural disasters is estimated at billions of dollars. The economies of countries in which natural disasters are being synchronized cannot recover on their own and need International assistance, especially the placement of climate refugees in other countries. An analysis of recent research and publications shows that its authors do not even pose such a problem. In the period from 2011 to 2020 alone, the number of natural disasters in the world increased 7 times, in particular in Europe – 41 times. The study shows that the concept of anthropogenic impact on climate change, sustainable development and possible adaptation through environmental and energy and resource conservation measures must be considered erroneous. International spending on climate change adaptation programs around the world is inefficient. The theoretical basis on which these concepts have been built so far needs to be revised, and the environmental policy of all countries of the world is subject to radical transformation. The practical significance of research is to improve the model of climate change, which is used to develop forecast scenarios for world events, based on the dependence of CO2 emissions. from anthropogenic human activity. Since the results of any mathematical model depend on the input data and the correlation of the relationships embedded in such a model, the percentage of reliability and probability of implementation of such a model is also estimated. Therefore, climate models developed at the initiative of the International Group of Experts on Climate Change cannot be used as a basis for substantiating recommendations for the transformation of agriculture in accordance with climate change.

This research aims to examine the performance of pineapple farming and the benefit of prima-3 certification and SLPHT in developing sustainable pineapple farming in terms of economic, social and environmental. This research compares the practice of pineapple farming management of certified, SLPHT and non-SLPHT farmer. The research location is in Astomulyo Village, Punggur Sub District, Central Lampung District. The sample in this research are 75 farmers that consist 15 certified farmers, 30 SLPHT farmers and 30 non-SLPHT farmers. The benefit of prima-3 certification and SLPHT in economic terms determined by farm income, meanwhile the pineapple quality assuredness, social and environmental terms analyzed using sustainability index. The different test of F test (One Way Anova) and Post Hoc Test LSD is used afterwards to analyze the assessment of pineapple farming. The results show that farm income of the first year to the third year sequentially for certified farmers are Rp57.450.792; Rp136.367.252 and Rp17.330.297, for SLPHT farmers are Rp54.169.465; Rp137.874.183 and Rp19.220.465, and non-SLPHT farmers are Rp55.326.879; Rp127.256.986 and Rp14.798.958. Prima-3 certification program and SLPHT in economic terms that is determined by farm income have not provided benefits, but the assesment result of pineapple farming management towards the increasing of the pineapple quality assuredness have provided benefits. As well as benefits in social and environmental terms showed that there's significant difference of the practice of pineapple farming management between certified, SLPHT and non-SLPHT farmers.

Despite a sufficient energy supply, harvesting energy from rainfall is essential for intelligent water management. A significant part is still untapped or little exploited, which is the renewable energy produced from rainwater. This paper proposes a portable gutter of the rainwater energy harvesting system to provide electricity that may be sufficient for powering lights and charging cell phones in rainy locations with limited electricity. A prototype is designed and tested to determine the feasibility of rainwater as a source of renewable energy. The aim is to minimize and respectively suspend the use of fossil energy sources, as well as decrease the percentage of pollution as it is a cause of global warming. The system prototype consisted of a gutter assembly that collected and funneled water from the roof to a downspout. The turbine was connected through a gearbox to a DC motor serving as the generator. The device is optimal during high rainfall intensities that produce larger flow rates. A smart algorithm has been applied, which is salutary to keep the system working and has the ability to control the flow of collected rainfall water. Also, this system is useful to install and use in the rural area where the national grids are not common and the level of rainfall is high. The applied system utilized and installed in more than one hundred premises can produce more than 4 kWh for one rain. In some countries such as Malaysia, the average number of rainy days is 250 days a year, so the use of this system in 100 premises can help to provide 80 MWh to the national grid yearly. The system is characterized by simplicity of design and lack of complexity in addition to ease of installation and cheapness, which is the basis for the availability of this system for use by everyone
