INDONESIAN JOURNAL OF URBAN AND ENVIRONMENTAL TECHNOLOGY VOLUME 3, NUMBER 2, APRIL 2020
Publisher : Universitas Trisakti

Aim: The objective of this paper is to review the impact of poor sanitation on global tourism development. Methodology and Results: The majority of the data for this study was sourced from World Development Indicators (WDI) dataset for more than 200 countries in 2014 from the World Bank. A regression analysis was applied to analyze the impact of access to improved sanitation on tourism development by using some indicators such as the number of tourist arrivals, the proportion of the population using improved sanitation facilities, and the proportion of the population using improved water facilities. The study found that the relationship between the proportion of the population using improved sanitation facilities and the number of tourist arrivals is significant. Poor sanitation has been shown to have huge negative impacts on public health and the economy. In terms of the economic impacts, the lack of access to improved sanitation causes economic losses related to the direct costs of treating sanitation-related diseases and the indirect cost of lost income through reduced productivity. Conclusion, significance, and impact study: Access to basic sanitation facilities is regarded as one of the aspects that should be considered to support the tourism industry, particularly in developing countries. This study suggests that providing sanitation is the best investment for promoting tourism. Decision-makers should act now, and in a concerted way, to provide adequate sanitation services and at the same time sustaining tourism growth as an essential aspect of a country’s economy.

Flare gas is light hydrocarbon gas, by product of any petroleum industry activities, that is flared; and it could not pass into production facilities due its to low pressure. The gas flare volume frequently is significant, causing greenhouse gas emissions which gives serious environmental issue. Aims: The purpose of this research is to utilize flare gas in oil and gas fields to reduce environmental issue. Methodology and Results: Flare gas in an oil producing field is compressed to produce higher pressure gas flow, by using three one-stage Integrated Reciprocating Compressors to enter the production trunk line. The gas is flown to CO2 Removal Plant, as the gas would be gas sales. The subject field in West Java, the production wells experiences pressure decline; resulting the wellhead flowing pressure becomes low, so the gas is being flared. The gas flare recovery system is economically profitable both for purchase and rental scenarios. Renting the equipment is more profitable and has lower technical risk, because all risks is burdened to rental service provider. Conclusion, significance and impact study: Monetizing flare gas will reduce environmental issue, and it is utilized for own use or gas sales. The best Economics Scenario is rental scenario.

Aims: This study aimed to increase the utilization of biomass-derived from the waste of coconut and peanut shells by making them as briquettes, as an alternative to fuel. The scarcity of petroleum because of its increasingly limited existence encourages all parties to take part in the development and discovery of new alternative energies. This is expected to overcome one of the most important of the many problems facing this country. The method used in this research is to start with a literature study of materials from various sources about the benefits and manufacturing of briquettes from biomass waste as an alternative energy source to be further tested for quality. This involves a heat test, water content test, ash content test and determination of the flying matter. Results: The test results showed that natural gas emissions were below threshold, namely 0-30 ppm CO, 0-3.6 ppm H2S, and undetectable NOx. After evaluation, the results showed that with the addition of 30% of the biomass, the ignition time was reduced and the remaining unburned briquettes or bottom ash was reduced by 68.68%. Conclusion, significance, and impact of study: The results help the community and the parties involved related to appropriate bio briquettes technology. It also eventually becomes one of the solutions to assist the government in solving problems related to alternative fuels to petroleum.

Aim: This study aims to assess the entire process of septage management comprising regulation, operational procedures, finance, community involvement, and water quality analysis to maximize the initial and hugest human fecal sludge treatment called Faecal Sludge Treatment Plant (IPLT) in Yogyakarta. Methodology and Results: The Modified EHRA (Environmental Health Risk Assessment) method was applied which focused only on wastewater treatment aspect. Several regulations including standard quality methods (SNI) were utilized and made a comparison between baseline rules and obtained results. Furthermore, quality assessment was accomplished by observation and interview. The results showed that the human sector needs to improve not only the amount of operators but also urgently put up protective personal equipment during the suction process. The dissemination of attractive information about sludge suction service done by PUPKP as a representation of the local government among the dwellers ought to upgrade a lot. Technologies employed which are carriage transportation and vacuum machine, are good enough. Contrarily, septage treatment plants require extra-effort to enhance it as most water quality parameters barely meet the standard quality. BOD, COD, ammonia, total coliform, oil and grease do not meet the third class of water quality (Government Regulation of Republic of Indonesia No. 82/2001). Subsequently, the effectiveness of each unit i.e. anaerobic tank and stabilization ponds are under 50% and the loading rate has a maximum capacity of 87.5m3/day, and 60m3/day minimum capacity. Conclusion, significance and impact of study: Therefore, almost all aspects of septage management in Bantul Yogyakarta are required to improve

COMMUNITY GARDENING AND THE CAPACITY TO ENRICH SOCIAL BONDING IN URBAN NEIGHBOURHOODS Shahida Mohd Sharif; Norsidah Ujang
INDONESIAN JOURNAL OF URBAN AND ENVIRONMENTAL TECHNOLOGY VOLUME 4, NUMBER 2, APRIL 2021

Aim: The aim of this concept paper is to identify a conceptual framework to investigate the level of social bonding/social attachment amongst participants of community gardening activity. It is estimated that more than 50% of the population would be living in urban areas by 2050. One of the drivers is the urban migration, where people are relocating themselves to new neighbourhoods, cities or countries often with the hope of better economic opportunities and social infrastructure, therefore changing the landscape of the new society and the place they reside. It is worrying as these people might not receive enough social support due to their limited social network. It could further escalate to social well-being problems such as individualism and social isolation and could later manifest mentally or psychologically as loneliness. Methodology and Results: This paper argues that the selection of the type of urban green spaces to be integrated into urban neighbourhoods is critical in addressing the well-being problems. Community gardens, as part of urban green spaces, offer meaningful social interaction opportunities, often being missed in the context of modern societies and urban lifestyle. Therefore, there is a need to review the effects of community gardening activities as an intervention strategy to strengthen the degree of social bonding to identify its capacity in integrating isolated people back into community life. Conclusion, significance and impact study: As a conclusion, urban designers and policymakers are suggested to adopt community gardens as a safe open space in cities to encourage more people-people-places interaction.
