Abstract

The process of aerobic composting the slaughterhouse (SH) solid waste generate ammonia emissions. Aim: The objective of this research to study the ability of the adsorbent to use zeolite to reduce ammonia gas emissions during the composting process of SH solid waste. Methodology and Results: Reduction of ammonia emission is conducted during the aerobic composting process which is 50 days. The raw material composition of the composting process used was 100% rumen contents, 60% rumen contents: 40% straw, 50% rumen contents: 50% straw, and 40% rumen contents: 60% straw. Zeolite used in the form of granular size 100 mesh. The result of the research showed that the level of release of ammonia gas emissions during the composting process could be reduced by zeolite. Conclusion, significance, and impact study: The efficiency of reducing ammonia gas emissions using zeolite adsorbents in the composting process of SH solid waste ranges from 98.09 - 99.40% on average. Zeolite is an adsorbent that has high adsorption power because it has many pores and has a high ion exchange high capacity and serves as an absorbent cation that can cause environmental pollution.

Abstract

Aim: This study aimed at comparing predictor variables associated with the environmental quality of first child. Since the beginning of 1987, Indonesian National Family Planning Board (BKKBN) has been discouraging early first marriage (marrying before 20 for females and before 25 for males). In 2016, BKKBN recommended ideal ages of marriage for females and males as old as 21 and 25 respectively. Methodology and Results: This study was a retrospective analysis involving 5 groups of data reported within the period of 1994-1997 (n=34,225), 1997-2000 (n=34,227), 2001-2004 (n=33,088), 2005-2009 (n=40,701), and 2009-2012 (n=45,607). Data were collected from the Indonesian Demographic and Health Survey datasets (SDKI [Survei Demografi dan Kesehatan Indonesia]). Data were analyzed using chi-square tests. Results indicated several variables that significantly contributed to the first child’s environment quality: (1) residential area (p value<0.05); (2) mother’s educational background (p value<0.05); (3) mother’s exposure to information media (p value<0.05); (4) mother’s employment status (significance were only found in two groups of data:  1994-1997 and 1997-2000 with each p value<0.05); (5) father’s educational background (p value<0.05).    Conclusion, significance and impact of study: In conclusion, there was an inconsistency with regard to strong and weak potential factors of first child’s environment quality within an eighteen-year period. It is recommended to reassess the predictors. It is also important to develop strategies to improve marriage quality and family formation.

Abstract

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.

Abstract

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.
