Authors: Chen Shan , Huang Hua 
Published: June 2020

Abstract
At present, the decline and disappearance of natural villages are widespread phenomena in China, with the appearance of problems such as one side of a thousand villages that are not conducive to the sustainable development of villages. China has a vast territory, and natural villages vary greatly in different regions. This study focuses on Hakka natural villages in Zengcheng district, Guangzhou city, Guangdong province. Taking Tangxia Village as an example, this study examines the heritage and evolution of a Hakka natural village space with reference to village site selection, homestead division, residential form, and public space. Several aspects that are not conducive to the sustainable development of villages are summarized in the paper, such as unreasonable site selection and homestead division, decline and vacancy of old buildings and low efficiency of new houses, and disappearance of the traditional style, etc. Comprising the largest proportion of villages in China, to a certain extent the development of natural villages determines the direction of sustainable development of the country’s rural areas. In order to explore the sustainable development path of natural villages, we must fully respect the local traditional culture and living customs, and the government, professionals and local residents should work together to maintain the lasting vitality of these villages.
Photocatalysts for Air Pollution Control and Abatement
Authors: Ghezzo F 
Published: June 2020

Abstract
Titanium dioxide (TiO2) has been largely studied in the past decades for its photocatalytic properties [1]. The material is a n-type of superconductor whose photocatalytic property is due to the absorption of photons (hv) with energy higher than the energy of the valence band. The electrons in the valence band use such energy to jump into the conduction band. This process, originally studied for the photolysis of water [2], has revealed itself of great use for the efficient removal of hazardous molecules and micro-organisms in water and in the air [3]. The high energy required by the electrons in the valence band to jump in the conduction band, which is 3.2eV for anatase TiO2, has limited the use of the material to the very narrow wavelength bandwidth of the ultraviolet (UV) radiation. In order to make use of the material under a much larger spectrum of light frequencies, especially under visible light, modifications of the TiO2 lattice by adding extra elements have been made and they still represent today a challenge for the research community. The change of the lattice can be done by doping TiO2 with different elements, this includes non-metal elements like carbon and nitrogen [4]. The importance of these studies stands on the fact that the resulting material, simply exposed to sun light or LED light, is able to sterilize the air from harmful bacteria and neutralize other well-known indoor volatile organic pollutants such as formaldehyde. This work presents some experimental observations on visible light photocatalytic carbon doped titanium dioxide, C-TiO2, obtained by a sol gel method. The study focuses on the crystal structure of the synthesized material. The aim is to evaluate the consistency of the method in reproducing the desired crystal structure and therefore the desired photo-catalytic properties of this material.

Published: June 2020

Abstract
Dye waste-water is one of the main sources of water environmental pollution, which belongs to the characteristics of refractory organic waste-water with large chroma, high concentration, large water quality difference, complex composition and large history of pH change. Physical, chemical and biological methods are the main methods on the treatment of dyeing waste-water. The advanced oxidation technology based on hydroxyl radical (•OH) has the advantages of strong oxidation, low selectivity and high elector-philicity. There are mainly seven ways to produce hydroxyl radical (•OH): Fenton oxidation, photo-catalytic oxidation, ozone oxidation, electrocute-chemical oxidation, ultrasonic oxidation, wet oxidation and super-critical water oxidation. These methods have significant effect on dyeing waste-water treatment.
Numerical Investigation of Flatback Airfoils Drag and Noise Reduction by a Splitter Plate
Authors: Song Ke 
Published: June 2020

Abstract
In this paper the aerodynamic and aeroacoustic characteristics of a wind turbine airfoil have been numerically investigated. The modified versions of TU Delft DU97-W-300 airfoil with a flatback trailing edge and a splitter plate were selected. IDDES method was introduced and provided good results compared with the experimental data with regard to the lift. Aeroacoustic analysis focused on the amplitude and frequency of noise associated with the vortex-shedding tone from the trailing edge wake. The results showed that wake flows were significantly effected by the addition of a splitter plate to the flatback trailing edge, and lead to reduction on both drag and noise.

Abstract
Sulawesi is an island that is affected by three main plate basins namely the Pacific Ocean plate, the Indo-Australian plate, and the Eurasian continent plate which produces several faults and causes intensive seismicity and other disasters in the region. Palu City as the Capital of Central Sulawesi Province is a disaster-prone area such as earthquake, tsunami and liquefaction. The impact of the disaster caused huge losses especially since the area has a high population. The importance of disaster mitigation plans in the area so that casualties, damage to public facilities, and other losses can be minimized. The mitigation plan consists of several stages namely the preparation, analysis, synthesis, and making the plan recommendations. Overall, Palu City is prone to disasters. The area that has a high level of vulnerability to 3 disasters has a total area of 446 hectares. Whereas for areas that have a high level of vulnerability to 2 disasters and 1 disaster has a total area of 3364 hectares and 3873 hectares respectively. There are 3 zones based on potential disasters in Palu City. Zone A is a zone that is prone to earthquake hazards. The total area of Zone A is 9100 hectares. Zone B is a zone for mangrove forest planting areas. The total area of Zone B is 572 hectares. Zone C is a zone that is prone to liquefaction hazards. The plant is expected to be able to absorb saturated ground water and reduce soil movement so it does not shift. The total area of Zone C is 1556 hectares. Disaster-prone areas are recommended to be relocated to safe areas in accordance with the recommended relocation locations. The recommended relocation area is on a flat slope of 6093 hectares and on a gentle slope of 5557 hectares.

Abstract
DKI Jakarta is a province with the highest population density (82.632 people per km2 in 2018). Jakarta can also be said to be the busiest province in Indonesia because it is the centre of the Indonesian economy. High-intensity activities in the middle of the city can cause stress and other health problems. These problems can be overcome by using the park. Park can be useful for solving health problems by providing places for physical activities and other outdoor activities that can help alleviate health problems. This study aims to understand the importance of the park for people health in DKI Jakarta and the relationship with the frequency of park visits. The study area consists of 10 urban parks located in 5 cities in DKI Jakarta. The number of respondents taken was 300 people divided into 30 people in each park. This study found that the proximity of the park to residence cannot be the main reason why they visit the park. Other factors which can affect frequency of park visits was the reason of visits. The visitors who lived far from parks want to visit the park because there were lots of shady trees so they thought it’s nice and comfortable to just sit and relax. Moreover, frequency of park visits can be beneficial for visitors’ health, especially increasing stamina, being more relaxed, and strengthen relationships with family or friends. Visiting and doing activities in the park at least once a week could provide greater benefits to the physical and social aspects of visitors than the psychological aspects. This meant that psychological benefits could be perceived even though not visiting the park once a week.

Abstract
Over these decades, tourism industry has developed very rapidly. Tourism evidently improves sustainability especially in rural by prosperity enhancement. Japan is nominated as the decade’s fastest-growing major destination with a 334% rise of arrival from 2010-2017. Moreover, Japan pulls out a tourism goal, aiming 40 million arrivals with JPY 8 trillion receipts by the year 2020. Rural areas are promoted to be tourist destination as an effort for sustaining rural landscape. But, it is not the case for Kita Village. Kita Village is one of famous rural heritage destinations located in Kyoto Prefecture with excellent Satoyama landscape. Residents of Kita Village agreed to preserve the Satoyama landscape through tourism. Maintaining a heritage site is not easy nor cheap. Economic needs couldn’t be denied to sustain the area. Tourists’ visitation is increasing each year, yet the tourism income is low. Therefore, increasing tourism income became an important issue in Miyama to sustain the Satoyama landscape. Literature have shown domestic and international tourists are different. With the increasing international tourists in Kita Village, this study aimed to explore each group and compare their consumption behavior. Tourists’ consumption behavior is studied to understand the tourism demands to increase tourism income in Kita Village, aiming for local revitalization and Satoyama landscape preservation. Data collected through a questionnaire survey in Spring. Results showed that expenditure between domestic and international tourists in Kita Village is not significantly different, JPY1954 for domestic tourists and JPY1994 for international tourists, yet the tourism attitudes between the two groups were different. Domestic and international tourists are significantly different in age, companion, transportation, times visited Miyama, duration, motivation, activity preference, and price preference. Expenditure is affected by marital status, age, duration, satisfaction, motivation, product preference, and price preference. This study managed to discover that the low tourism receipt from international tourists is mainly due to the incompatibility of the type of program. While for domestic tourists, the low tourism receipt is mainly due to the high price offered. It is suggested to make tourism program development as priority for tourism development.

Abstract
Indonesia’s capital city, Jakarta, is surrounded by several satellite cities and has grown spatially into a larger region called Jabodetabek. The development in Jabodetabek has resulted in changes in the landscape. The increase of impervious surface and decrease of green space has led to the formation of an urban heat island (UHI). UHI could be detected through land surface temperature (LST) monitoring. Therefore, the objectives of this study were to analyze the land cover changes in Jakarta and its satellite cities and to analyze the impact of these changes on LST using GIS-based analysis. We analyzed Jakarta and its three satellite cities, Depok, Tangerang, and Bekasi, through a satellite image time-series analysis in 1989/1990 and 2015/2018. It is found that, among the four cities we analyzed, Tangerang has the highest built-up area expansion proportion, followed by Bekasi with a slight difference, then Depok and Jakarta. As for the LST, the city that has the most significant difference between mean LST in the initial and recent year is Bekasi with 12.66°C, then followed by Tangerang (11.05°C), Jakarta (8.34°C), and Depok (6.43°C). These orders’ inconsistency might be caused by higher proportion of built-up area combined with higher loss of vegetated area. This shows that the land cover change played a big role in the temperature increase.

Published: June 2020

Abstract
Oil and gas are strategic, non-renewable natural resources and are vital commodities. It is explained that upstream business activities are business activities that are cored or rely on exploration and exploitation. While downstream business activities are business activities whose core are in processing, transportation, storage and/or commercial business activities. At present, 68% of the world’s energy needs are derived from fossil fuels. Fossil fuels that are often used include coal, petroleum and natural gas. The results of the 2007 Intergovernmental Panel on Climate Change (IPCC) study showed that the concentration of CO2 gas in the pre-industrial period amounted to 278 ppm, while in 2005 it was 379 ppm. The consequences of this change are rising global temperatures by 0.74°C, and there has also been a sea-level rise of 0.17 m, then there has also been a 7% reduction in snow cover in the northern hemisphere and rivers experience slower freeze. The contribution of greenhouse gas emissions from the oil and gas sector is expected to increase from 122 metric tons (Mt) of CO2 in 2005 to 137 metric tons (Mt) of CO2 in 2030. Emissions produced by crude oil exploration in 2015 amounted to 48,947.35 tonnes of CO2e and increased in 2016 amounting to 232,950.30 CO2e. Therefore, an LCA study is needed as a solution to reduce the emissions of greenhouse gases CO2, CH4, N2O, NOx and SOx at a company in East Java. The purpose of this study is to determine the environmental impacts generated by crude oil exploration. The emission data of CO2, CH4, N2O, NOx and SOx, mass balance, the amount of raw materials, fuels used and emissions produced in each of the main process units and supporting units, as well as data on the amount of products produced from petroleum production activities in one company in East Java, are used to determine the impact on the environment that would arise through the stages of LCA analysis using the Eco Indicator 99 method in the SimaPro 8.5.2 software. The results obtained from this study revealed that the process which has the highest impact value on the environment is the process of producing oil in the PV-9900 separator unit, with an impact value of 12620 MPt and the value of each category of damage was 4,76 × 1011 MJ surplus for the “resources” category, 0,00118 DALY for the “human health” category and 0,0847 PDF⋅m2⋅year for “ecosystem quality” category.

Published: June 2020

Abstract
The Region of Jombang in East Java has Gedangkeret Landfill as its final solid waste management system. There are 50 transfer stations that are mostly located in the district of Jombang. The other transfer stations are located in the districts of Diwek, Peterongan, Mojowarno, Mojoagung, Ploso, Ngoro, Gudo, Perak, Sumobito. These transfer stations produce at least 76.11 tonnes/day of solid waste. The composition of the solid wastes dumped in this landfill is mostly food waste and plastic. The presence of biodegradable wastes will produce plenty of greenhouse gasses. The leachate produced is processed in stabilization ponds, but the value of BOD and COD is still below the quality standard. The Index Score of Gedangkeret Landfill is 538.48, indicating that the landfill needs to be rehabilitated. The rehabilitation plans comprise of dumping zone stabilization, drainage system, leachate processing, landfill gasses management, and greenbelt plan. The dumping zone planning is based on population projection. The drainage system planning is based on the Jombang climate condition. The leachate processes planning is based on the leachate flow rate on each dumping zone and its characteristics. The greenbelt planning is based on the CO2 production and the conversion of the methane gasses.

Published: June 2020

Abstract
The leachate produced in municipal mixed waste landfill contains mostly organic pollutants in various forms. Biological treatment that popularly applied for the treatment only capable of removing biodegradable portion of the organics whilst the recalcitrant parts will leave the system untreated. Therefore, a pretreatment prior to biological process to increase biodegradability of leachate is essential. The physicochemical method such as electrochemical oxidation is an appropriate pretreatment alternative because it has high efficiency in degrading such pollutants. The purpose of this study was to examine the effect of flow rate (1.5 and 5 mL s−1) and anodes (boron-doped diamond (BDD) and dimensionally stable anode (DSA)) on the efficiency of electrochemical oxidation process to degrade leachate. The parameters analyzed were COD, BOD, ratio of BOD5/COD (biodegradability index, BI), TDS and pH. The results showed that the increase in BI when BDD and DSA used were 0.386 and 0.179, respectively. The best COD removal was achieved by BDD and DSA at current density of 30 mA cm−2 with the flow rate of 5 mL s−1. BDD could remove 83 % COD (1.56 g) while DSA 68 % (1.08 g) with specific energy consumption of 0.00268 kWh g−1 and 0.00186 kWh g−1, respectively.
