Authors: Solikhah B , Yulianto A , Suryarini T 
Published: April 2020

Abstract
Issues related to the green industry and environmental accounting are urgent to be formulated by the government. The concept of environmental accounting for companies encourages the ability to minimize environmental problems. Environmental accounting will produce a quantitative assessment of the costs and impacts of environmental protection. The purpose of this study is to describe the extent of disclosure of carbon emissions and to describe the legal regulations in Indonesia which regulate ecological disclosure. This study also examined the effect of the Environmental Performance Awards on the quality of environmental exposure. The samples are 35 companies engaged in mining, energy, chemistry, pharmaceuticals, cosmetics, food, and beverages that are listed on the Stock Exchange in 2012-2016. The data analysis method used is Ordinary Least Square (OLS). The result reveals that the practice of environmental disclosure at high profile companies on the Indonesia Stock Exchange is still low. This shows that the company’s management awareness of environmental exposure does not comply with the Decree of the Chairperson of the Capital Market and Financial Institution Supervisory Agency Number: KEP-431/BL/2012 concerning Submission of the Annual Report. The results showed that the Environmental Performance Awards variable had a significant positive effect on the quality of environmental disclosure.

Published: April 2020

Abstract
Poverty and environmental issues are correlated. Many reports suggest that poverty contributes to environmental degradation. Therefore, it is believed that the improvement of the quality of the environment must be started by alleviating poverty. The objectives of this study are to find the impact of poverty to environmental degradation and vice versa. This study uses data panel from 33 provinces in Indonesia from 2012 to 2017. Contrary to the belief, the result shows that the effort to reduce poverty resulting in environmental degradation. On the other way, one of the findings shows that the efforts to improve the quality of environment resulting in a high level of poverty. This implies that there is a consequence of reducing poverty, i.e. low quality of the environment. The trade-off occurs because when the government tries to reduce the poverty rate, then the quality of the environment also reduces. If the government wants to improve the quality of the environment, then the level of poverty will increase. This study suggests that the government must carefully conduct the poverty alleviation programs that create less harm to the environment and the government also needs to make regulations to protect the environment without harm the poor.

Published: April 2020

Abstract
This study aims to examine the effect of financial market development, investment, and trade openness on the environmental quality of East Asian and Southeast Asian countries from 1991-2017. Differences in the influence of the East and Southeast Asian region on environmental quality indicators are accommodated by using the dummy variable of the region. All data is sourced from World Development Indicators - World Bank. The results of this study reinforce the notion that per capita income (GDPCap), the environmental effects of financial market development (FMDev), Foreign Direct Investment (FDI), trade openness (TL), influence according to the hypothesis. The Empirical Kuznets Curve (EKC) hypothesis was empirically proven in both regions. Capital inflows and trade openness negatively affect environmental quality, while financial market development (FMDev) has a positive effect on environmental quality in both regions

Published: April 2020

Abstract
Urban growth drastically changes the biophysical environment, including in the form of replacing the soil and natural vegetation with urban material, which causes urban areas to be warmer than the surrounding suburban and rural areas. This phenomenon which is commonly referred to as Urban Heat Island is regrettable because it increases energy consumption for the needs of air conditioners as well as thermally uncomfortable conditions for activities. This study aims to identify the phenomenon of Urban Heat Island in one of the largest metropolitan areas in the world, namely Jakarta, the capital of Indonesia, and the surrounding area. In this study, the UHI phenomenon was identified based on the spatial pattern of surface temperature obtained by processing the Landsat 8 OLI/TIRS remote sensing satellite image data. The results showed that the developed land has a higher temperature than the land with natural cover and land that is overgrown with plants, namely forests and agricultural land. The spatial pattern shows that land surface temperature decreases with increasing distance from the Capital City of Jakarta

Published: April 2020

Abstract
Pandeglang Regency has the potential of a tsunami disaster due to its location, which is close to the megathrust segment of the Sunda Strait. The tsunami disaster caused negative impacts such as death, loss of property, and damage, which could be lessened by increasing community resilience aimed at reducing the disaster risk. Community resilience is related to the community’s ability to recover from shocks or pressure to its original state. A resilient community can return to its previous state relatively quickly. It is crucial to know the tsunami disaster resilience index in Pandeglang Regency to obtain recommendations or concepts for tsunami disaster mitigation that are appropriate in creating community resilience to tsunami disasters in Pandeglang Regency. The purpose of this study was to measure community resilience to the tsunami disaster in Sukarame Village, Carita District, Pandeglang Regency using The Integrated Concept of Community Resilience (ICCR), which was adjusted to the conditions of the study area. Measurement indicators are developed based on internal and external factors that affect community resilience, such as social, cultural and economic capital, disaster risk governance, and disaster-based spatial planning. The analysis is based on data from the household questionnaire, which is then transcribed into statistically analyzed indicators. The results show that the combination of the social, cultural and economic capital, as well as the disaster risk governance index is medium, while the disaster-based spatial planning index is low. The ICCR index in Sukarame Village is in the medium category. It is necessary to improve disaster risk governance and disaster-based spatial planning in this area to reduce the tsunami risk that may occur in the future.

Published: April 2020

Abstract
Brackish water has a salt content between 500 to 17000 mg/l. If people consumption of brackish water, it impacts health problems and making plants wither or die. Groundwater become brackish is caused by sea water intrusion. Therefore, desalination technology is needed to process brackish water into fresh water. Natural material is predicted to be an alternative for desalination process. Natural zeolite is more used because they have abundant excess availability, lower operational costs, and have a high adsorption. More research is needed to determine the right activation method for zeolite so that the effectiveness of decreasing salinity can increase. In the initial study using natural zeolites with chemically activated, the reduction efficiency (ɳ) reached ∼ 99.54%. From the results of these natural treatment, zeolite have the ability to reduce of salinity. This article is a review of several previous studies.

Published: April 2020

Abstract
A refrigeration system uses Ammonia Anhydrous in the liquid phase and the gas phase. The refrigeration system has the potential for gas leakage, which poses a risk to worker safety as well as environmental pollution to water bodies and air pollution. This risk might have an impact on employees in the factory area and could extend to the surrounding community. This study is intended to be able to analyze the risk of pollution accurately before installing the refrigeration installation. In this study, the analysis method that will be used is the statistical method and the use of mathematical models supported by Aloha software. The distribution of pollutants from ammonia gas leakage is influenced by several factors, including the capacity of the refrigeration system, meteorological conditions, and land use. The use of Aloha software in the prediction of zones affected by the spread of toxic substances in the atmosphere can calculate and predict the area affected by leakage events. With modelling done, will get a map of concentration and impacted area. The direction and magnitude of the impact of pollution will be known immediately, and the potential losses that may arise will be minimized.

Abstract
Geothermal, in global discourse, is approved as renewable and environmentally friendly energy. This has made rapid developments in recent years, one of which is in Indonesia. Even so, this discourse was not well explored for the local community. Thus, they do not get the correct information about this energy. This research aims to study people’s perceptions about the development of geothermal energy. This research is a case study in Pauh Duo Subdistrict, Solok Selatan Regency, Indonesia, where the MuaraLaboh geothermal power plant was developed. We use descriptive quantitative methods and are supported by survey methods to get people’s opinions about the development of geothermal energy. The results show the fact that people still have limited knowledge about geothermal energy. This is caused by the lack of socialization by the government or companies regarding geothermal energy.

Published: April 2020

Abstract
Yogyakarta is the city with the raising in population growth every year. Population growth demands more land and water consumption. Land-use changes from natural to a built-up area like residential or commercial areas will increase the load of the land and decrease the water infiltration area. The intensively land-use changes have been lowering the ground-watersurface with an average rate of 30 centimeters per year. The increase of land load and the lowering of the ground-water surface are implications of land subsidence. This study aims to map and to estimate the rate of land subsidence in Yogyakarta City. This study used remote sensing technology, especially an active remote sensing system. An Interferometric Synthetic Aperture Radar (InSAR) technique applied form Sentinel-1 radar satellite imageries can show the location and pattern of land subsidence. This study shows that there is subsidence in the city of Yogyakarta. The total subsidence that occurred in 2015 to 2017 did not show any specific pattern, whereas in 2019 & 2019 there was an increase in the intensity of subsidence in the southeast.

Abstract
Inundation occurred in high density urban areas is a major issue especially in low land because it potentially damage the affected infrastructure. In this research, a case was taken in Kelayan Regional Inundation Handling Unit in Banjarmasin City, South Borneo. The purpose of this study is to determine cause of the inundation and provide recommendation for reduced it. The hydrological analysis was calculated by using the rational method, using data from Sungai Tabuk Rain Station that 24 years long. From the discharge obtained, then the required channel dimensions could be calculated and compared with the existing channel dimensions. The hydraulic analysis was performed by HEC-RAS model with the discharge as boundary condition, and topographic data to determine channel elevation. As the results, the existing drainage channels can only cover 39.85% of the entire area, and almost all of these existing channels cannot drain the discharge that occurs, therefore it becomes an inundation. For example, channel number 4.C.14c the existing channel has 0.5m width and 0.7m depth, it caused inundation as high as 39cm upstream. After normalized the channel by increasing the dimensions to 2.1m width and 1.3m depth, the discharge does not overflow so there is no inundation.

Authors: Mizwar A , Surapati H U 
Published: April 2020

Abstract
Indonesia as a country that has the largest mangrove area in the world, of course contributes significantly to global climate change. It is known, the mangrove area is an area with abundant biodiversity. The existence of various industrial activities, such as oil palm plantations or special coal port operations make the mangrove area can receive negative impacts. Bio-indicators are living organisms such as plants, planktons, animals, and microbes, which are utilized to screen the health of the natural ecosystem in the environment. They are used for assessing environmental health and bio geographic changes taking place in the environment. The ability of microorganisms to reform the biodegradation process is an indicator of pollutants in the waters. In the process, microorganisms require or consume more dissolved oxygen (DO). So, the higher the concentration of BOD5, the concentration of dissolved oxygen (DO) in water is reduced. This research uses the grab sampling method, which is done 4 times in one year for water quality sampling (BOD5) and aquatic biota samples. The results of this research, showed a significant positive correlation regarding the concentration of BOD5 on biodiversity in mangrove areas. Thus, BOD5 concentration can also be used as an bio-indicator of the quality biodiversity of mangrove areas.

Authors: Priyambada I B , Oktiawan W 
Published: April 2020

Abstract
The purpose of this study was to analyze the effect of leachate recirculation on decreasing organic pollutant content in leachate which was investigated in a laboratory-scale experiment using simulated landfill anaerobic biorecators (lysimeters). Leachate used in this study was artificial leachate which was made in high concentrations (BOD 3, 758.19 mg/l and COD 7, 406.67 mg/l) and low concentrations (BOD 641.30 mg/l and COD 1, 279.33 mg/l). Leachate recirculation was carried out on biodegradable waste in reactors with two operating conditions. The first group of reactors was operated with high concentration leachate and the second group was operated with low concentrations leachate. Each operation condition is carried out on 10 reactors which were arranged in series, while the reactor R1 as a control (single pass reactor) was operated without leachate recirculation. Recirculation is carried out every day for 90 days. BOD and COD in leachate samples were regularly monitored every week with two repetitions (duplo). The results indicate that leachate recirculation further increases the reduction of BOD and COD concentrations when compared with reactors without leachate recirculation. Removal of BOD in R1 reactors with addition of low and high concentrations leachate are 68% and 68.13% respectively. While removal of BOD in reactors with addition of low and high leachate concentrations are 83.98% and 92.15%. In general, reactors with leachate recirculation have higher BOD and COD removal compared to reactors without leachate recirculation.

Published: April 2020

Abstract
This study aims at understanding the interaction between various mycorrhizal sources and three local cassava varieties of Gunungkidul, specifically on their compatibility, population, mycorrhizal diversity, and their effect on cassava growth. The experiments were conducted based on Completely Randomised Design (CRD) with experimental factors using three treatments in triplicates. The experimental factors included three cassava varieties and various sources of mycorrhiza. The results demonstrated that among the interactions of various mycorrhizas with three local cassava varieties of Gunungkidul, the highest infection was seen from Mentega cultivar inoculated with indigenous mycorrhiza of the Alfisol soil of Gunungkidul (95%). Mycorrhizal diversity using indigenous mycorrhiza of Alfisol soil was higher than mycorrhiza of pandan rhizosphere and commercial inoculant, and the dominant mycorrhiza type was of spores belonging to genus Glomus. On the other hand, the indigenous mycorrhiza of Alfisol soil inoculant on various cassava varieties demonstrated similar effect and yielded the same number of spores, root length, and plant dry weight; despite the fact that on Kirik cultivar growth, the significant difference was observed on the plant height, leaf number and fresh net weight.

AbstractSynchytrium pogostemonisis a fungal pathogen causes budok disease of patchouli plant. A research to control the disease was conducted at Indonesian Spice and Medicinal Crops Research Institute. The research was purposed to evaluate effectiveness of mix combination and single formulas of citronella, clove, and neem essential oils against the disease. Two synthetic fungicides (benomyl and bourdeaux mixture) were also tested, as well as, water as a control treatment. One month-old patchouli plants were sprayed with single and mix combination formulas of those three essential oils (5 ml/l), benomyl (3 g/l), bourdeaux mixture (1 g/l) and water as much as (100-200 ml/plant) every two weeks for 5 times respectively. The result indicated that the mix essential oil formula of (neem+citronella) was the most effective in reducing budok disease incidence. Its effectiveness was higher (56.51%) then benomyl (47.82%) and bourdeaux mixture (52.18%). The mix formula of (citronella+neem) could be recommended for controlling budok disease of patchouli. The use of essential oil mix formulas, hopefully could control budok disease, inhibit the resistance of target pathogen, reduce phytotoxicity and concentration of the more toxic essential oil once, as well as, reduce the uses of synthetic pesticides.
