Abstract
Air quality degradation has been reported in Jakarta during 2019. Air pollution in the urban area is attributed to anthropogenic activities and influenced by meteorological parameters. This study attempted to investigate the effect of a meteorological parameter such as Mixing Level Height (MLH) to PM concentration and its seasonal variation in Jakarta during 2019. PM concentrations are obtained from BMKG and United States Embassy; meteorological parameters, as well as radiosonde observation, are derived from Soekarno Hatta Meteorological Office. Seasonal and diurnal variation of PM concentration and its relationship with MLH have been assessed. The study found that PM increased during the dry season (DS) and decreased in the rainy season (RS). During DS, frequency of occurrence of PM10 (PM2.5) concentration that exceeded the national and WHO standard were 2.2% (6.5%) and 96.1% (65%) respectively. Daily variation of PM2.5 mass ranged from 0.05 to 11.72 times of the PM10 and increased during RS. The MLH is negatively correlated with PM concentration. PM monthly concentration is always higher in the morning with the lowest MLH, particularly in DS. Radiation inversion type is the most common with height is quite low at 115.30 m causing high PM concentration of 59.17 µg/m3 (PM2.5) and 122.67 µg/m3 (PM10).

AbstractTapioca processing from cassava produces abundant solid wastes. If left untreated, it potentially increases greenhouse gas emissions from the decomposition of organic matter. These gas emissions are known to accelerate global climate change. Tapioca solid waste (TSW) has high starch and cellulose content, making energy recovery possible through conversion to bioethanol. This research aimed to produce bioethanol from TSW by a co-fermentation method of baker’s and local tapai yeast. The research was conducted through multi-stages of enzymatic hydrolysis, followed by fermentation, then distillation. The hydrolysis produces hydrolyzate with a relatively high reducing sugar concentration. The ethanol fermentation results were optimally achieved in 48 h, namely substrate fermented by tapai yeast first for 24 h, followed by the addition of baker’s yeast and fermentation time to 48 h. This proces produced the highest yield and bioethanol concentration, almost 2 times higher than fermentation using baker’s or tapai yeast only. This results suggested that TSW can be used for bioethanol production by co-fermentation of baker’s and tapai yeast method. TSW usage will reduce global warming, bioethanol production can be widely applied in various fields replacing fossil fuel, thus has the potential to reduce global warming and global climate change.

Abstract
Gerbangkertosusila region is a prime mover of regional economic activity within East Java Province and even the national level. The impetus for economic growth has an impact on the carrying capacity of the environment. Thus, to achieve sustainable development goals, it is necessary to conduct a study of environmental carrying capacity which is related to the maximum capacity/entropy that can be utilized by the human being. An ecological footprint approach is an approach of the environmental carrying capacity to identify the components of natural resource consumption, waste, and availability of natural resources in each type of land use. Carbon footprint which is the biggest part of the ecological footprint has a relation with CO2 emission production, which influences climate change mitigation. The purpose of this study was to formulate land use control policies based on the ecological footprint approach. The analysis method consists of three phases. First, the calculation of biological capacity was based on the availability level of natural resources. Second, the calculation of an ecological footprint was based on the consumption level of natural resources. The final phase was sustainability calculation to get the result to accommodate the population consumption within the region. The finding showed that Mojokerto City, Surabaya City, and Sidoarjo Regency were regions which a deficit in terms of ecological sustainability. The rest regions within the Gerbangkertosusila region were considered regions that are experiencing a surplus. It has a surplus of 87,424,615 gha or equal to 9.13 gha/capita.
Application of bridle model in estimating greenhouse gases emissions from three wastewater treatment plants in Fukushima Prefecture, Japan
Authors: Pratama M A , Setiarini J 
Published: April 2021

Abstract
The estimation of Green House Gases (GHGs) plays an important role in reducing emissions to prevent global warming and climate change. The Intergovernmental Panel on Climate Change (IPCC) method is the most commonly used in estimating the emissions from a wastewater treatment plant (WWTP). However, it is difficult to establish technical strategies in emissions reduction as the method cannot identify which treatment unit contributes to the total emission. In this study, we estimated GHGs from WWTPs using the Bridal Model based on the operations and processes in each treatment plant unit. We applied the model to three WWTPs located in Fukushima, Koriyama, and Nihonmatsu City, Japan. The results were evaluated by comparisons with those estimated by the IPCC method. The bridle model results showed that the average daily GHG emissions in Fukushima, Koriyama, and Nihonmatsu in the 2015-2018 period were 86.4, 55.2 and 6.2 ton CO2 eq/day. Furthermore, emissions from the three WWTPS per m3 of treated wastewater were insignificantly different from those estimated by the IPCC method. Sludge treatment was the most sensitive treatment unit as it contributes to 31.8-70.3% of the total emission, followed by chemical and biological treatment units. The study suggests that utilizing biogases produced from the sludge treatment could reduce 21.4-49% of total emissions from a WWTP.

Abstract
Climate change is the challenge provided with the most attention within all circles in the 21st century. This phenomenon allegedly originates due to the increasing concentrations of CO2 gas in the atmosphere. Therefore, efforts are continually designed to slow down or halt the process to avoid significantly impacting life on earth. The common mitigation approach is by encouraging the planting of trees to optimize CO2 sequestration. This study, therefore, aimed to determine the CO2 sequestration capacity of Aquilaria malaccensis in natural forests and plantations. Particularly, Aquilaria malaccensis is an endemic plant of Indonesia’s tropical forests, with critical or endangered status. The allometric method was adopted, with purposive and non-destructive sampling techniques, then a multilevel plot was used during CO2 sequestration analysis. This plant species absorbed the gas at the tree category in natural forests (9.57 tons CO2 eq/year), and similarly with plantation forests (2.35 tons CO2 eq/year). The tree biomass category in natural forests (5.22 tons CO2 eq/year), and plantations (1.28 tons CO2 eq/year), alongside the pole category in natural forests (1.9 x 10-3 tons CO2 eq/year) rank lowest. The carbon content in the tree category ranked highest at the natural (2.61 tons CO2 eq/year), compared to plantation forests (0.64 tons CO2 eq/year), while the carbon composition in pole category at the natural and plantation forests were (9.8 x 10-4 tons CO2 eq/year) and (2.2 x 10-3 tons CO2 eq/year), respectively.

Abstract
This study aims to identify the conflict of norms in the mineral and coal sectors particularly after issuing Law No. 3 of 2020. The type of this research is normative-legal research, which analyses the contents of some relevant Indonesian Law and some principles of law on Mineral and Coal. The data are qualified as the primary legal materials and collected through study documents. They are then analysed qualitatively. The main findings show that there is norm conflict post Law No. 3 of 2020 on the Amendment to Law No. 4 of 2009 on Mineral and Coal is enacted. The norm conflict can be seen in Indonesian sustainable development policy and law, such as Indonesian sustainable development the Law No. 16 of 2016 concerning Ratification of the Paris Agreement to the UNFCCC, The Presidential Regulation of No. 59 of 2017 concerning the Implementation of Achieving the Sustainable Development Goals, and the Low Carbon Development concept. Both the national policy and the Law will have significant effects on Indonesian commitment to reduce GHGs by 2030 to 29% with business as usual and to 41% with international supports. Relation of it with climate change issues is both the national policy and the law only accommodate the interests of coal industry players. but not the interests of the people in the mining areas and indigenous peoples. It means that the accommodation of mineral and coal industries’ interests will threaten the environment, as it is known that they are one of the worst contributors to GHGs in the world.

Abstract
Peatlands store very high carbon stocks. Damage to peatland ecosystem will have an impact on increasing greenhouse gas (GHG) emissions and increasing the risk of climate change. Peatlands governance is important to prioritize the principle of conservation over cultivation. The aim of this study is to analyze and elaborate the conflict of interests between the Roundtable on Sustainable Palm Oil (RSPO) and Indonesia Sustainable Palm Oil (ISPO). The methods are normative-legal research to diagnose the difference in the application of law between RSPO and ISPO. The findings show that RSPO as one of the world sustainable palm oil management standards has banned palm oil planting on peatlands based on its 2018 Principles and Criteria for the Production of Sustainable Palm Oil (P&C). Unfortunately, the palm management instrument in Indonesia which is ISPO still provides space for palm oil cultivation on peatlands. Relation of this study with climate change issues is that ISPO ideas are counterproductive to Indonesia’s commitment in reducing GHG emissions by 29% in 2030. Indonesia needs to evaluate peatland governance policies to prioritize conservation rather than cultivation.

Abstract
Environmental reporting is a means to communicate the environmental performance information by an organization to its stakeholders. Information on environmental performance among others comprises the impact of the organization’s operation on climate change, the environment, performance in managing those impacts, and contribution to ecological and sustainable development. This study aims to examine the association between environmental reporting, ownership structure, and corporate characteristics, namely financial performance, board gender, and company size. Ownership structure was measured by managerial ownership, while financial performance was measured by liquidity, solvability, and profitability ratios. The study uses one hundred and twenty-eight manufacturing companies listed on the Indonesia Stock Exchange (IDX) in 2017 as a sample. Results of multivariate regression analysis indicate that managerial ownership and profitability have a positive association with environmental reporting. These results suggest that the higher the shares owned by the management, and the more profitable the company, the higher the incentives to disclose environmental information in the company’s annual report. The study provides additional insight into the capital market authority agency regarding factors that may influence listed companies to report their environmental awareness under the Global Reporting Initiative (GRI) G4 environmental framework.

AbstractDisaster is one of impacts caused by climate change. The Audit Board of the Republic of Indonesia conducts an audit of state finances management and responsibility in handling the disaster. The success of The Audit Board of the Republic of Indonesia was partly driven by The Audit Board of the Republic of Indonesia’s internal audit performance, namely the Inspectorate General which provided consultations to add value for the The Audit Board of the Republic of Indonesia work unit. However, The Audit Board of the Republic of Indonesia work unit expects that Inspectorate General has more consultative and not impressed as an external auditor in carrying out the consultation. The purpose of this research was to improve and enrich the communication of Inspectorate General internal auditors in carrying out the consultation. This research used symbolic interaction theory by George Herbert Mead. This paper is a compilation of several relevant data sources. They were collected systematically, and then analyzed in-depth and critical evaluation to provide the research finding in narrative. The result showed that management of mind, self, and society can play important role in carrying out the consultation. Besides, the use of symbol and nonverbal communication may increase good relationship in the consultation. Inspectorate General needed to improve its auditors competence to manage symbolic interaction in carrying out the consultation in order to be more consultative.

Published: April 2021

AbstractBali as a famous tourist destination in Indonesia has major problems related to the environment and climate change. Garbage until now has been felt by most of the people in Bali but it is still underestimated. A series of regional regulations (Perda) and traditional regulations (awig-awig) have attempted to address the issue. Based on this the environmental preservation movement is now increasingly vigorous, while the Balinese Hindu philosophy of life “Tri Hita Karana” in the life of modern Balinese society appears just like a discourse. The aim of this research is to analyze the role of Bali Arts Festival to environmental preservation. This research was conducted using quantitative and qualitative methods at the largest routine arts and cultural festival in Bali known as the “Bali Arts Festival”. The results show that from the exhibitor`s perspective Bali Arts Festival has played a role in preserving the environment through its craft exhibition.
Analysis of the income and household welfare of organic and non-organic rice farmers in the Sambirejo Sub-Regency of Sragen Regency, Indonesia

Published: April 2021

Abstract
Climate change can be caused by various factors, including carbon emissions. The adoption of an organic farming system on a large scale can reduce the use of chemicals in factory production. Therefore, in the long term, it can reduce the operation of chemical factories and reduce carbon emissions. However, the organic system cannot be applied extensively to Indonesian rice farmers. The complexity of the system, certification, the initial decrease in production, and higher cost allocation leads farmers to think that the organic system is not making an impact on their income and welfare. This study aims to determine the farming income, household income, and household welfare of organic and non-organic rice farmers in the Sambirejo sub-district. It uses a descriptive method, and the respondents were determined by the proportional random sampling method. The results show that the organic rice farming income and household income are higher than their non-organic equivalents. There is a very small difference in the price of organic and non-organic rice of only IDR 855.00/kg, so it is understandable that many non-organic farmers are reluctant to switch to the organic system. Based on the comparative test of the Rice Farmer Exchange Rate, the welfare of organic rice farmers is higher than non-organic ones, whereas, based on Food Expenditure Share, the welfare of organic rice farmers is not significantly different to their non-organic compatriots.

The purpose of this literature review is twofold. First, it shows the state of the art of the subject matters and the second one is to identify the main topics of the current research. This review was conducted by finding the keywords related to climate change and tourism in the literatures. This literature review was conducted semi-systematically by searching well-known digital libraries using keywords related to tourism sectors and climate change. A total of 24 literatures were identified as relevant to our inclusion criteria. Required information was extracted from these 24 literatures and grouped into each topic. The result is, current research on impacts of climate change in the tourism sector in Java Island is mainly focused on the threat of extreme weather to the tourism sector. Extreme weather directly linked with the tourism sector by significantly decreasing the number of visitors. Another important point to highlight is the change of adaptation pattern in societal, governmental, or private sector institutional level is also an important topic to be examined thoroughly in further research
Environmental friendly “Jambur” building relevance in Karo Batak communities and gotong-royong/sisampat-sampati communities in Covid-19 pandemics
Authors: Tarigan N P 
Published: April 2021

Abstract
It can be an exciting and positive thing to realize an Indonesian-style building in a location from certain ethnic groups like the Karo Batak. Notably, suppose they collaborated with social empowerment where they live so that the diversity of Indonesia’s ethnic groups will be more colorful in cooperating or working together or in the “Sisampat-sampati” in Karo Language. In that case, this can be built by creating approaches for developing the character of ethnic groups and in person. Developing the character of a person or ethnic group in Indonesia will make the Indonesian people better in the future, because in principle, these characters are formed from many national cultures, such as respect for nature and others. Indonesia is very friendly or likes to communicate and interact, so that the use of social media in Indonesia can be said to be very broad and the third largest for several types of social media. However, whether this has excellent implications for increasing the quality of life or significant quality of life is still a big question especially Sustainable Development Goals (SDG) number 13, climate change. However, with a hypothesis that mutual character building is the right answer, the researcher is pleased to provide input from a broader view of character development itself and architecture. This will undoubtedly bring significant changes to the nation in the future. This paper is a conceptual article or literature study and input from several journals.

Published: April 2021

Abstract
The Environmental Management System (EMS) has an essential role in promoting inclusive and sustainable industrialization to support climate change. However, it is considered to be less desirable by industries in Indonesia. Meanwhile, the Ministry of Environment and Forestry has issued the Company Performance Rating Program in Environmental Management (PROPER) as a driving force for industries in Indonesia. The EMS ISO 14001 is an obligation in the PROPER assessment. This study aims to design a stakeholder perception model related to the ISO 14001 implementation. The method employed in the research is in-depth interviews with expert stakeholders. The result is a qualitative model of stakeholder perception, which shows that there is a relationship between motivations, costs, and benefits in the application of EMS. The perception of industries revealed that the cost of EMS implementation is greater than the gained benefits in the short term, yet more benefits are favored in the long-term. Therefore, government involvement is necessary to increase the motivation of industries in both the short-term and long-term. This study also revealed the key aspects to optimize EMS implementation in Indonesia.

Published: April 2021

Abstract
The 2006 Yogyakarta earthquake with a magnitude of 6.3 happened with presumption due to activity from the Opak fault. After the earthquake, the activity of the Opak fault continued to be monitored by using Global Positioning System (GPS) technology. GPS data can be used to see the characteristics of deformation, which happened until present after the Yogyakarta earthquake in 2006. The characteristics of the deformation caused by the earthquake can be either afterslip or viscoelastic relaxation, where each of them can be approached by using a logarithmic and exponential function. The results show the data from continuous stations shows better results compilation approached with an exponential function, which means the deformation of the Opak Fault depends on the interseismic phase with still potential as viscoelastic relaxation of material which lies on the lower crust. Then, the results of the exponential parameters are used to correct the velocity for all GPS stations. The statistical result shows that only the velocity of the continuous stations is significantly different from the velocity before being corrected.
