Abstract
Community-based Sanitation Communal Wastewater Treatment Plant (WWTP) is one of the solutions for dense urban areas to improve environmental quality. This paper evaluates wastewater treatment plant-based Community participation in Community Self-Reliance (KSM) Mandiri, Metro City, Lampung. The methods used are quantitative with laboratory tests resulting from the effluent of Communal WWTP conducted in the dry season in September and qualitative with interviews with board member and local facilitators. Communal WWTP uses an anaerobic filter and uses biofilter that is used from recycled plastic bottles. Laboratory management results show that the BOD and Ammonia parameters do not meet the standard requirements of the Ministry of Environment and foresty 68 of 2016 about Quality Standard of Domestic Wastewater. The activities of the WWTP management group at KSM Mandiri did not run well and needs help for the government fundings to maintenance WWTP. Additional biofilter WWTP component and zeolite are needed to reduce BOD and ammonia levels of effluent and local community involve to every process in this program.

Abstract
Pekalongan City is a filariasis endemic area in Central Java, Indonesia with Mf-rate >1%. It had held Mass Drug Administration (MDA) in 2011-2015. The evaluation result recommended it to re-hold MDA. This study aimed to compose filariasis vulnerability zonation based on environmental and behavioral aspects in Pekalongan City. The observed environmental aspects were the location of shrubs, cattle pen and tidal flood. The surveyed behavioral aspects were applicating mosquito repellent and hanging clothes habits. Filariasis cases data were collected from health office. This was a descriptive quantitative study with spatial approach. The environmental and behavioral aspects were observed and surveyed in 6 urban villages (38 RWs) with 387 households as samples which were chosen with proportional random sampling. The instruments were checklist sheets, Global Positioning System (GPS), satellite imagery and GIS software. Data were analyzed with scoring, buffering and overlaying procedures. Results indicated some areas were categorized as highly vulnerable where shrubs, cattle pen, tidal flood and hanging clothes habit were present. It was concluded that all urban villages in this study had highly vulnerable RWs which are very potential for filariasis transmission. Applicating mosquito repellent habit was not potential aspect for controlling filariasis transmission in the studied areas.

Abstract
Land and forest fire in Indonesia has been the annual environmental crisis for the several last decades. The Gunung Merbabu National Park is one of the areas with the most land and forest fire event. The event usually occurred during dry months. On October 2018, the Gunung Merbabu National Park lost 400 hectares of forest area due to the fire events. This fire event caused by both natural and un-natural factor from the burning activities. The fire event will endanger natural biodiversities, damage the animal habitat, and change the environment and ecosystem condition. This study aims to identify the prone area for land and forest fire in the Gunung Merbabu National Park. This study used Normalized Difference Vegetation Index (NDVI), and Normalized Burn Ratio (NBR) extracted from Sentinel-2A imageries to classify the land-use/land-cover and to detect the burned area in the Gunung Merbabu National Park. The prone area analysis will also consider the accessibility distance from the center of the community activity in surrounding areas

Abstract
This research proposes a business model for furniture industry to address circular economy concept. Circular economy aims to keep the resources in use for as long as possible, and recover the product and material at the end of its life cycle. Game theory is used in this research. The conceptual model proposes rent option so end users are possible to use the furniture in desired time period. Using rent option, the product could be taken back from the end user and could be sold or rent it again to another user. The concept of game theory is to formulate and suspect the situations of interaction between players involved, and also decisions taken. Therefore, game theory is used to determine optimal strategy among players. Player strategies are taken when it has reached the Nash Equilibrium. The propose model consists of 4 parties such as the furniture industry, remanufacturer, distributor, and end user. Payoff is determined for every player to observe each players- profit in addressing CE. Based on the result, there is 1 strategy that reached the Nash equilibrium. We also picked out 3 of 162 possible strategies that give the best advantages for all players. Each strategies contain players- prices decision, and for end user decision is the length of rent.

Abstract
Plastic waste in Indonesia has become global issues, where Indonesia itself has been stated as the second plastic waste polluter in the world. Semarang City, as one of the major cities in Indonesia, is facing plastic waste problems. Reverse logistic network for plastic waste recycling seems to be used as alternative method to reduce the emissions of plastic waste recycling. In this study, the reverse logistic network of plastic waste is evaluated based on the estimation of greenhouse gases (CO2, CH4 and N2O) generated from recycling activities. The results showed that the largest GHG emissions came from plastic waste grinder (intermediates) for about 0.513 Tonne CO2eq/day. According to the calculations, the optimal number of recycling businesses is 224 units of scrap dealers, 358 units of small scale entreprises, 23 units of large scale entreprises, and 18 units of grinders. Total greenhouse gases produced from the 623 recycle business units are 0.932 Tonne CO2eq / day. Optimization of existing reverse logistics scenarios is needed to evaluate greenhouse gas emissions before and after optimization.

Abstract
Access to safe water as a basic infrastructure is still a major problem throughout the world, and it is the main concentration to be solved as stated in SDGs pillars 6 and 9. Availability access to basic needs such as infrastructure of water is also one important homework to deal with for the Indonesian government along with the Universal Access 100-0-100. The main research aim is to measure the Water Poverty Index through the 5-component to propose a poverty eradication strategy of the water infrastructure at the community level. Jabung District in Malang Regency is chosen as the case study, consist of 15 villages, wherein at about 33,19% of households are the receiver of Raskin (Poor Rice) program – one of the poverty alleviation programs in Indonesia. Both field observation and depth interviews are conducted towards 548 heads of households at the compiling data. The WPI measurement indicates that 3 of the 15 villages have the unsafe value of WPI. Among the fifth component, the environment shows the worst scale of the WPI whereby 7 villages have a value of 35,7 (critical value), so integrated water management strategy by incorporating water balance for both domestic and non-domestic purposes is indispensable.

Abstract
Green Open Space (GOS) is a solution in anticipating future environmental crises by developing a city with a sustainable principle. The increase in the physical area of the city has the consequence of reducing the area of GOS. Meanwhile, along with population growth and economic activity in turn it will spur changes in land use in various parts of the city. Depok City faces problems related to the availability of GOS due to land conversion. The area of GOS in Depok City tends to decrease over time. Identification of the distribution of GOS that is still available needs to be done as one of the efforts to build a database to monitor the existence of existing GOS. UAV Drone is a breakthrough in the novelty of technology in mapping a region. The aim of this study is to map existing public and private GOS areas and analyze the area that has the potential to develop GOS, especially public Green Open Space using UAV Drone in Depok City. From the provision of GOS allocation of at least 30 percent, The Government of Depok City is able to provide 16.33 percent GOS. The figure of 16 percent is a combination of public Green Open Space (proceeds from municipal government) and private (owned by residents). Potential areas to be used as public Green Open Spaces in Depok City include the sub-districts of Pancoran Mas and Beji. The both of sub-districts are expected to increase the public Green Open Space in Depok City, in addition, some residential housing in the both of sub-district, can be created private Green Open Space such as making a field and a park.

Abstract
The 4.0 industrial revolution in all fields encouraged the construction industry to make technological-based innovations. Building Information Modeling (BIM) is one of the tools in advancing construction technology today. On the other hand, supply chain construction continues to grow and becomes important in project management. This study aims to identify the potential use of BIM in construction supply chain management. Preliminary studies on several projects in Indonesia were carried out as identification methods. The Delphi process was used to obtain the data described in the Strength, Weakness, Opportunity, and Threat (SWOT) analysis. As a result, BIM has the potential to be applied to the construction SCM with several considerations. There are 5 trends in strength, 4 trends in weakness, 5 trends in opportunity, and 3 trends in threat. Trends in strength and opportunity are used as indicators in the analysis of impacts. BIM as advanced technology is the highest indicator and the lowest trust between stakeholders in the application of BIM in the construction supply chain. In addition, harmonization between BIM actors is needed: the Ministry of Public Works, contractors, suppliers and academics in the supply chain.

Abstract
The problem of flooding in a Watershed (Basin) or region is basically caused by natural conditions, such as relatively high rainfall, sloping topographic conditions and tidal influences. Human behavior is often also the cause of flooding problems, such as the location of settlements that are in the river borders or industries that dump waste directly into river bodies. Besides the problem of flooding can also be caused by not well organized river/drainage system or lack of maintenance of an existing river/drainage system. Furthermore, social problems include increasing demands for the availability of new and good residential environmental infrastructure. To overcome the problems as described above, before an activity such as build in a left/right inspection road planning, is need analysis rainfall data and make patterns of Intencity Duration Frequency (IDF) Curve to analysis of hydraulics in determining flood discharge plans. The results showed that the IDF pattern can be described as a form of rain return period curves in the Air Lakitan Watershed and the entry point for suitable environment to approach of technical analysis for flood control.

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 vegetables and fruits 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 of 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.

Abstract
At present, the use of medicines, especially antibiotics, has increased significantly, and this affects domestic waste. The human population contributes to the spread of antibiotic residue into the environment either via excretion of pharmaceuticals during the ordinary course of treatment or by improperly disposing of unused medication in toilets. This study aims to study the effect of pharmaceutical residues, particularly antibiotics, on the removal efficiency of ammonium and COD in domestic wastewater, using anaerobic batch reactor. The reactor inoculated with a septic tank and an artificial waste. The stages of this research were seeding, acclimatization, and running. This research was conducted for 30 days with the reactor volume at 8.5 liters of seeding and acclimatization time and 1.5 liters of running time. Efficiency removal of COD were 89.66%; 88.24%; 85.21%; 78.27% and 77.72%. Meanwhile, the efficiency removal of ammonium are 55.08%; 53.30%; 48.13%; 40.36% and 32.16%. The reactor with the highest pharmaceutical residue did not contribute to the efficiency of COD removal but affected the effectiveness of ammonium removal.

Abstract
The 2030-s core agenda for 17 Sustainable Development Goals aims to bring systems thinking and holistic solution to ensure that progress and development for People and Profit do not actually side-line Planet as the major stakeholder. Any discussion on the Economics issues should bring in the Environment and Socio-cultural diversity dimension as equal components. This may necessitate a complete revamp of human activities such that effort to tackle famine and poverty and the emerging infectious diseases, is not divorced from addressing the problems brought about by the climate change and the destruction of eco-systems and habitat for wildlife. The call for greater utilization of green technology and sustainable practices must involve resource optimization and better management of biodiversity, agro-practices, environment and health care to achieve improved food production and distribution, affordable cost of disease treatment, cleaner energy, air and water, with minimal emission, pollution and wastage. The focus of this presentation is to highlight research and development in integrated biomaterials engineering of oil palm fibres and microalgae for sustainable bioenergy production, environmental remediation and conversion into value added-products via integrated palm oil milling processes and algal biorefinery. This hopefully could bring forth insights towards partnerships and collaboration among the policy makers and planners, industrialists, investors, scientists, engineers, economists and social scientists to tackle the immediate and pressing problems facing the world today.

Abstract
Composting Process is an alternative organic waste management for degradation waste generation. In general, bioactivator will be added to the organic waste mixture which aims to accelerate the process of maturing compost and not forgetting the quality standards of it in order to apply to the soil so that the environment will stay in a healty condition. There are various types of bioactivators that used in the composting process such as EM-4, Acticomp, Orgadec, and also bacteria which can be produce using various source organic matters such as vegetable waste. Vegetables waste is a good medium for growing microorganisms, and it can be use as bioactivator in the composting process. Another advantage of using this source is that vegetables waste are cheap and easy to find because they usually thrown away and not reused. Some researchers found bacterias like Streptococcus, Leuconostoc, Lactobacillus, and Pediococcus are contained by vegetables that will create lactic acid fermentation .This bacterias has an important role to change various sugars in vegetables waste, especially into lactic acid which when compost is given to the soil, bacteria will play a role to control the pathogenic organisms. Some studies about bioactivator from vegetables waste relationship has been done related to the compost quality result from the addition of the environmental biaoctivator from vegetables. In this article, there will be reviews from various research journals related to the making and application of bioactivator from vegetables in the composting process and to find out whether the use of vegetables waste are good bioactivator for composting process.

Abstract
Geothermal, in the global discourse, is said to be one of renewable and environmentally friendly energy. This has made the development of rapid progress in the last few years, one of them in Indonesia. Even so, the discourse is not well explored to the local community. Thus, they assume that geothermal energy is the same as other non-renewable energy and that it has an impact on their social acceptance. This study aims to determine the perception of local people about the development of geothermal energy, especially their perception of the sustainability of the surrounding environment. This research is a case study in South Solok Regency, Indonesia. We use a mixed-method namely survey and in-depth semi-structured interviews to get the views of local people about geothermal energy development. The results showed that local people have low knowledge of geothermal energy. This is caused by poor public communication by the government about the technology involved in the production of geothermal energy so that uncertainty about environmental and social impacts is a factor affecting the perception of local communities.

Abstract
The availability of land that is an unrenewable resource is an important component of house fulfillment for low income communities. Unified Database recorded in 2018 there were still 6083 backlogs based on the status of residential ownership in Semarang Regency. There is no denying that the high number of backlog was influenced by the increasing population, one of which is caused by urbanization. On the other hand, relatively cheap residential area is limited, which caused the house prices to be higher and made it more difficult for low-income household to fulfill the need for shelter. The 1945 State Constitution said that the State has an obligation to fulfill the right to get shelter and health. The purpose of this research is to know if there is an adequate land for the fulfillment of subsidized housing in Semarang district based on the availability of existing land and its capacity observedfrom the backlog in each sub-district. The method used in this research is quantitative method with overlay analysis on GIS of land availability that are affordable and suitable for spatial layout. The second method is a scoring analysis and a weighting analysis which were used to determine the priority of alternative locations for subsidized housing. The result of this research showed that the availability of land that are in accordance with the spatial layout and relatively inexpensive in Semarang district is still quite widespread, which is about 338.08 Ha. The capacity can then be calculated from the analysis results. The land suitable for subsidized housing which has an area of 338.08 Ha can accommodate a population of 135,232 people. Land capability can be known from the comparison of the backlog number with the capacity of the residential space that is 24,564 < 135,232, which means has been fulfilled. Meanwhile if we analyze from the sub district level, there is scarcity of land for the fulfillment of subsidized housing in several districts, among others are District Tengaran, Susukan, Kaliwungu, Tuntang, Banyubiru, Ambarawa, and Ungaran Barat. Those districts have no potential land for the fulfillment of subsidized housing while the backlog numbers are quite high.

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-water surface with an average rate of 30 centimeters per year. The increasing of land load and the lowering of the ground-water surface will have implications on 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 of land subsidence. The result from InSAR will be compared with data from other optical imageries to analyze the factor of the subsidence.

Abstract
Construction projects are large-scale works that are mostly done in open areas. This large and open activity has the potential to produce waste and carbon footprint. Therefore, the purpose of the research is to find out the causes, impact analysis, and possible mitigation of waste and carbon footprint in construction project. Survey and in-depth interview to construction project become research method. The results showed that the causes of waste were dominated by worker factors. While the main causes of waste in the design phase are client requests, DED changes and complexity, and design errors. Meanwhile, carbon footprint occurs because it does not use renewable energy and environmentally friendly materials. The impact of indirect waste is 8.93% of the total workers budget while direct waste is 5.64% of the material budget which is at the contractors tolerance threshold of 3-6%. Carbon footprint in the production phase still dominates the contribution to the amount of carbon footprint produced when compared to the transportation, fabrication and installation phases.

Abstract
Issues related to 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 environmental disclosure. This study also examined the effect of the Environmental Performance Awards on the quality of environmental disclosure. The samples in this study 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 Structural Equation Modeling (SEM) with a Smart PLS 3.0 analysis tool. 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 companys management awareness of environmental disclosure does not comply 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.

Abstract
Global warming is becoming a serious concern day by day. Indonesia still uses a large portion of fossil fuels in electricity generation, has made matters even worse due to carbon emissions. Government through PP No. 70 of 2009 issued an energy conservation policy stating that energy use must be carried out economically and efficiently. The objective of this policy for all sectors of life, not to mention the academic environment. Library spend a lot of energy consumption for support that activites especially in the lighting system. Observations and measurements were performed to see the illuminance of the library because when seen visually very bright. The results are then compared with the standard, whether it meets the minimum threshold or not or even exceed, and how the savings opportunities that can be done. The method that used in this research is data collection, measurement of illuminance, and search for savings opportunities through simulations. Based on methods, a savings opportunity is obtained by reducing the number of lamps used. If this step is applied then obtained savings of up to 514 kWh/year, equivalent to the electricity bill amounting to IDR 462.672.000, - from the lighting system.

Abstract
The island of Mantehage is one of the island clusters within the Bunaken Marine Conservation (Taman Laut Bunaken). A cluster reaching out to 89.065 hectares and consisting of the island of Mantehage and four other islands; Nain, Manado Tua, Siladen and the infamous island of Bunaken. Clean water has been a major issues amongst these island dweller in the far Northern regions of North Sulawesi, thus is one of the priority agenda that needs attention. Clean water availability issue has also been a major issue to the villagers of Bango Village on Mantehage. 120 households of the Bango Village only relies on a well at the center of the village. A well that is currently utilized for all activities of washing and cleaning of all villagers, in which this facility is not accomodated with public bath and wash rooms. This program of community development was conducted and funded by the PPDM multiyear scheme of KEMENRISTEKDIKTI-s DRPM. In which this program was aimed to revitalize the village water supplies and facilities. This program prepared a unique water tower with a capacity of 5500 liters and designed to compensate the uniques environmental challenges of island dwellers in terms of humidity and high salinity exposure. Recycled light steel guage material was used as the main tower frame for low cost and low maintenance reasons within a coastal environment, besided the fact that the material is recycled and thus considered a green material. The whole system is then equipped with 3 stage filtration system that is easily maintained with filtration materials that are simply found in the surroundings of the village.

Abstract
Abstract. Many factors affect the impaired lung function capacity. This study aims to look at the determinants of lung function capacity. The study was conducted at Tirtonadi Terminal. This study uses an observational design with a cross-sectional design. The population of workers was 54 people after the inclusion and exclusion criteria from the total population. a sample of 50 workers was taken using a random sampling technique. dust measurement based on SNI 16-7058-2004 uses a low volume sampler and is carried out at 06.00-10.00, 14.00-16.00. the measurement point is carried out at the west and east gates as the highest concentration of pollutants Measurement of lung function capacity using spirometry. Other variables were assessed using a questionnaire and a checklist sheet to determine the characteristics of the study respondents. The results showed significant levels of environmental dust, work area and use of significant masks with impaired lung function capacity with p-values = 0.003, 0.005 and 0.001. The use of masks during work must be a must for workers to protect from dust exposure which generally comes from motorized vehicles. Keywords: Environmental Dust Exposure, Lung Function Capacity

Abstract
To support the academic activities at Diponegoro University, water is extracted from groundwater by submersible pump. Due to the utilization of the pumps, it requires electricity that increases the consumption of energy. The use of energy at the same time will also raise the amount of CO2 emission produced. The emission is produced from the outcome of the power plants fuel combustion. Moreover, the excessive underground water withdrawal will lead to the decreasing of the land surface. The amount of emission produced during one year is analyzed in a form of carbon footprint with the units of weight of carbon dioxide(kgCO2eq). This research conducted at the Diponegoro University main campus which located at Tembalang, Semarang. The method used was based on IPCC Guidelines for National Greenhouse Gas Inventories 2006 and Ministry of Environment 2012 about the Implementation of National Greenhouse Gas Inventories Guidelines. While the analysis of carbon footprint mapping used ArcGIS software. This research showed that the estimated amount of carbon footprint from the clean water sector is 77.623,6733 kgCO2eq/year. Carbon footprint mapping presented three level classifications of carbon footprint, those are lower, middle, and upper which are represented of green, yellow, and red colors. The efforts to reduce carbon footprint produced from the clean water are using a sensor faucet which can reduce carbon footprint by 69,96 %, toilet dual flush, and doing a regular checking of the faucet, urinoir, toilet, the need Standard Operating Procedure, water saving socializations, green open space and use of the central reservoir which can reduce carbon footprint by 16,83%.

Abstract
Higher education is one of the most critical stages of education in a country. Most experts in various fields become proficient through higher education. Therefore, providers of tertiary education or tertiary institutions must continuously improve the quality of their education. One way to improve its quality is by mapping university excellence. This mapping was held to see the advantages of each provider in Indonesia. As an education center, as well as a research center, one that can be used as a basis for mapping is scientific publications. In this study, the superiority to be seen refers to RPJPN 2005-2025 and RPJMN 2015-2019 and mapping based on journals in SCOPUS 2014-2018, which focuses on Information and communication technology. This mapping was carried out by the Ministry of Research, Technology and Higher Education, Republic of Indonesia (KEMENRISTEKDIKTI) with an assignment research scheme for strategic policy studies with a focus on information and communication technology. The results of the research discussion conclude that ITB (Bandung Institute of Technology) which has the most of total journal publications for the field of Information and communication technology focuses on 1313 journal publications.
