Abstract
The types of window, either permanent or impermanent will influence the building thermal profiles. Natural ventilation is one of technique to create passive cooling design in the building. It can improve the quality of indoor air, thermal comfort and reduction of energy consumption for air conditioning. In this present work, a study on the type of natural ventilation and the effect to thermal building performance was conducted. There are two types of natural ventilation as main variable in this study, top hung window and jalousie window. To develop the study, a simulation used Computational Fluid Dynamics (CFD) also conducted. One natural ventilation as outlet also added in the simulation. Based on the data measurement and computer simulation, jalousie window can provide better thermal performance. The range of difference between indoor air temperature on the chamber with jalousie window and chamber with top hung window is 0.2°C to 0.5°C, showing greater heat loss. The average of amount on the indoor air flow also was found 0.0317 m/s higher in the chamber with jalousie window. Particularly in the inlet, it was clear that the velocity of incoming air flow is faster and significantly allowed greater air with lower temperature entered from outside to inside.

Abstract
Indonesia is boosting infrastructure development, including in the connectivity sector and electricity supply, where coal fired power plants are most widely used and spreaded throughout the archipelago. Coal burning activity will produce ash namely, Fly Ash and Bottom Ash (FABA). Indonesia Government considered FABA as Hazardous and Toxic Waste (B3) in category 2 from specific sources, due to its chemical and physical variations and massive volume. By 2019, the production of FABA are predicted around 6.598.493 tons. It is predicted that this volume will increase along with government policies on the 35,000 MW program which must be fulfilled by 2024. Therefore, technical utilization of FABA is needed so that it does not pollute the environment due to improper handling. The purpose of this research is to study the utilization of FABA from Labuan Angin coal fired power plant as a road pavement material that not only fulfill the required specifications, but also has better performance and environmentally safe. The reseach method was laboratory experiment, which consists of FABA characteristics testing, and mixtures for road pavement testing. Criteria for utilization of FABA as a road pavement material, must be carried out with the use of substances that capable to binding FABA so that it does not come off. Waste of FABA will be assessed for use as hotmix asphalt, concrete, and base layers. The test results showed that Fly Ash (FA) of Labuan Angin was type F with levels of CaO more than 10 percent and LoI: 4.27 percent. Characteristics testing of FABA also showed results such as specific gravity of FA 2.64 and BA 2.56, absorption of BA 3.24 percent, and sand equivalent test was 95.35 percent. The results of the study shows that for asphalt and concrete mixtures, FABA from Labuhan Angin was less effective in use. In asphalt mixtures, waste that can be used is fly ash i.e as a filler with a low volume of only 5 percent. For concrete mixtures, results of concrete mortar test shows that the FABA from the Labuan Angin is not suitable for geopolymer concrete because it cannot provide workability in the mixture. In addition, a conventional concrete mixture with OPC cement was experimented but a large amount of water was needed which reached 95% so that the strength at the age of 7 days only reached 8 until 14 MPa. In the utilization for road base layer the results shows that the composition of 75 percent bottom ash, 25 percent fly ash, and 9 percent PCC cement produces a maximum density γd = 1.71 percent, optimum moisture content = 5.84 percent, and Unconfined Compressive Strength (UCS) 33.05 kg per cm2 of the required value of 25 to 40 kg per cm2. Utilization for foundation layer is most effective, because in addition to being able to absorb more waste, the binding process of cement and compaction with heavy equipment can also prevent waste of FABA from released so it is environmentally safe.

Abstract
Social movements often emerge as a response to repressive actions taken by the government towards the community. The main entities that become movers in social movements are civil communities, be they NGOs, social activist groups, or communities with various other backgrounds. Moreover, in the context of geothermal energy development that is still not fully understood by the community, social movements develop with rapid dynamics. Therefore, the purpose of this study is to look at the dynamics that occur within civil society groups in West Sumatra in developing a discourse about the rejection of the construction of geothermal power plants in the Talang Mountain area. The dynamics in the form of communication, interaction, exchange, and involvement. This research is in the form of case studies that focus on civilian communities that oppose geothermal development in the vicinity of the Talang Mountain Area. This area is considered as one of the biggest geothermal producers in Sumatra and even in Indonesia, but on the other hand, it is also a region rich in biodiversity and economic resources and clean water for local communities. Data collected through field observations, interviews, and documentation. The results showed that the development of shared discourse between communities is an important factor that can unite the perceptions, ideas, and movements of the community. The development of the discourse did not occur structurally. However, because of liquid exchanges of communication, there are joint actions, and literacy activities as a form of exchange of ideas between them. Although not completely able to stop the development process, the social movement increased the publics critical power.

Abstract
North Kendeng Mountain has abundant of limestone potentially utilized for cement material, cosmetic, paint and other commercial products. This area is also a storage for water resources widely utilized for household and irrigation for local people. Conflict between government and investors on one side preferring this area for utilization for commercial uses and local people supported by influential people and academician choosing it for conservation. Such conflict have been running since 2006 in the district of Sukolilo, Pati Regency, followed by similar conflict in the district of Tambakromo and Kayen, Pati Regency in 2012 and the latest conflict started in 2014 in the district of Gunem, Rembang Regency. To strengthen their efforts, local people pioneered by Sedulur Sikep (Adat or Traditional Community) form Community Network for caring North Kendeng Mountain or JMPPK consisting of local people at North Kendeng Mountaian Area, influential people and academician across Indonesia. JMPPK mobilizes people in defending their area to be conservation through cultural events, rally, demonstration, dialog, discussion and lobby. Based on their environmental wisdom, Sedulur Sikep believe that they have to treat the Earth as a mother providing everything for human being. It is compulsory for human being to treat the Earth in a good manner. This paper observes the development of conflict over water resources, the way JMPPK defends their right over natural resources. The type of research is descriptive analysis. The data collection techniques include informal interview, observation and literature review. The data is analyzed qualitatively. To incorporate aspirations, needs and interest of local people, it is required a dialog among relevant stakeholders regarding the area for utilization and conservation.

Abstract
Most of anaerobic digesters in Indonesia are run under mesophilic condition because Indonesian climate is sufficiently good to easily maintain mesophilic condition. On the other hand, thermophilic anaerobic digestion offers an advantage of much higher biogas production rate, although it needs more tedious control and energy supply to achieve the thermophilic temperature of 50-60°C. We run laboratory scale experiments to compare process performance of anaerobic digestion of bioethanol liquid waste (vinasse) at mesophilic and thermophilic conditions. Digested cow manure was used as inoculum. Start-up was conducted with only the inoculum inside the reactors. After the reactor passed through the starvation period, the vinasse feeding was started. The hydraulic retention time (HRT) was gradually decreased from 60, 42, until 30 days. Each step of HRT took 7 up to 14 days for stabilization. At the same HRT, thermophilic reactors produced biogas at the rate of four times faster than the mesophilic reactors. The methane concentration in the biogas for thermophilic process was relatively the same as the mesophilic one. With such higher rate of biogas production, the energy cost for thermophilic can be possibly better compensated.

Abstract
Air pollution has been a serious problem in recent years. Air pollutants consist of gaseous pollutants, odours, and suspended particulate matter (SPM) such as dust, fumes, mist, and smoke. SPM has the potential to cause environmental and health problems. With the aim to anticipate the impact, SPM prediction from time to time is needed. In this research, we compared four models for predicting the SPM data. The two linear models selected were ARIMA and wavelet whereas the two nonlinear models were neural networks based models, i.e. General Regression Neural Network (GRNN) and Cascade Forward Neural Network (CFNN). All four models are built with the same input, which were the past data at the same lagged time based on the best ARIMA model. By using lagged time data as input, the goal is to predict the current of SPM data. Model accuracy is measured based on MSE values, both in training and testing data. Data processing has provided interesting results that show the superiority of nonlinear models over linear models, especially in the training data.

Abstract
Lead pollution of soil is a serious global problem due to risk of entering food chain and ground water contamination. Anthropogenic activities such as mining, smelting, agriculture and industry have played an important source of Pb in soil. Cinangka is a Pb-polluted area impacted from the processing of used batteries since the 1990s. Although serious government efforts have been made, the remediation has not yet been completed because of insufficient resources. Therefore, it needs periodical monitoring and follow up. This research aimed to study the condition of lead pollution in soil and groundwater in the former battery recycling in Cinangka Bogor. Specifically the study was focused on Pb level in topsoil, Pb geochemical fraction distribution and environmental risk assessment, Pb profile on the soil horizon, and groundwater contamination. The geochemical fractions of Pb were determined by sequential extraction with a modified BCR method followed by AAS measurement. The results showed that the soil in the former recycling center contained Pb above 10,000 ppm which was dominated by reducible fraction (F2) and acid soluble fraction (F1) having moderate environmental risk. Vertically until 45 cm depth, the deeper the soil the lower the Pb content and the ground water in the study site did not show any lead contamination. We recommended immediate sustainable remediation of the contaminated site.

Abstract
Fresh water snail (Pila ampullacea) is large fresh water snail that can be found in rice fields, ponds, lakes and marshes. Most of them live in paddy fields and become pests for its plant thus the farmer tries to eradicate. Whereas, aquatic animals especially snail contain high level of protein with an amino acid profile similar with the meat land animals, thus making it beneficial to health in countries where snail exists. Thus, fresh water snail can be used as a raw material in producing foods or snacks, one of the famous snack in Southeast Asian countries is cracker. Pila ampullacea was obtained from the swamp and was cleaned it up by removed the flesh from its shell and used the water then production of the crackers. Nutrition contents of the fresh water snail cracker is protein (10.67%) and lipid (0.06%). The organoleptic analysis of crispiness was shown good result with mean score is 4.1.

Abstract
Every construction project consumes a huge energy. The impact of energy consumption on environment is remarkable in developing countries. Sustainability infrastructure has become a crucial issue among decision makers, developers and designers around the world. Value Engineering program is one of method for improving project sustainability. This method present whether a decision increases or worsen the projects performance. While the goals of value engineering program are dominated by cost and time reduction. Case study is carried out on Automated People Mover System (APMS) project. APMS project, at Soekarno Hatta International Airport, is the first skytrain in Indonesia. The length of APMS track is 3.05 kilometres. The concept of a simple span bridge structure is used for APMS tracks. On APMS project, the initial design of the girder used the PC-U type with rarely-used dimensions. By using value engineering program, stakeholders decided to replace PC-U type with the PC-V type which has common dimensions in PT.WIKA BETON as a supplier. The use of PC-V type girder gains the benefit of efficiency in terms of time and cost. The production and erection time of the PC-V girder is more fast 30 days. Besides, The PC-V Girder saves production costs by 2 billion rupiah. This paper also attempts to give several recommendation for designing sustainable developments by focusing on the bridge structure as the main unit.

Abstract
Most of waste cooking oil (WCO) in Semarang is still disposed in landfill since there is inadequate number of facility to collect those wastes. There are only three collection centers of WCO identified in Semarang. The alternative to sell WCO is also not the best option as the amount of WCO generated from household is less than culinary enterprise. Thus, having a collection channel that can thoroughly cover all the supply points of WCO from household in Semarang is a necessity. This research is going to design a collection channel in order to provide facilities so the waste can be properly managed. The research determines the number, location and capacity of each collection center. The number, location, and capacity of collection centers are determined using Maximal Covering Location Problem. The finding shows that to facilitate all the potential supply of WCO in 1 km mileage, 146 collection centers.

Abstract
Population growth in sub-urban areas in developing countries is very fast in excess of the ability to provide public facilities. Clean water infrastructure has a challenge where most of the water sources are taken from unsustainable groundwater. Intake of ground water results in various environmental problems such as a decrease in groundwater level and landsubsidence. The distribution system has a high level of leakage, the service has not been continuous 24 hours, and very low pressure is still often found in various locations. The research explains the strategy in changing groundwater sources into surface water sources. The optimization of the drinking water distribution network is carried out by evaluating the network system using epanet software and then doing the rehabilitation design and network development according to future developments. The results of the analysis of the epanet model show that the use of deep well pump systems directly distributed to customers results in inefficiencies from pressure. Access to safe drinking water needs to be prepared first from the availability of raw water, treatment units to the distribution network. The construction of clean water transmission pipeline system is prepared to go into a different zoning from the initial network. Zoning pumping network systems will increase pressure significantly and reduce leakage through control.

Abstract
The problem of traffic congestion often occurs as an impact of the population and economic growth in Semarang City, especially in the city centre. One strategy to deal with traffic congestion in mixed space use areas is to apply the concept of Transit-Oriented Development (TOD). The purpose of this study is to identify the location of potential TOD areas in Semarang City, analyse the needs of developing the TOD area, then formulate the direction for the development of the TOD area. The method was the quantitative descriptive approach which was supported by map overlay. Data collection techniques were carried out by primary survey through questionnaires, interviews and field observations, while secondary surveys were applied by collecting scientific data from government agencies and related literature. The analysis consists of identifying the location of potential TOD areas, identifying the characteristics of potential TOD areas, analysing the needs of developing TOD areas, and analysing the embodiment of TOD areas. Based on the results of location identification, the potential TOD area in Semarang City is in the Simpanglima Region. The Simpanglima area is a centre of economic activity and public services with high building density including a transportation node and is passed through several modes of mass public transportation. The application of the TOD concept in the Simpanglima Region is expected to increase accessibility and mobility to reduce congestion, reduce environmental pollution, as well as the efficient use of energy in the transportation sector.

Abstract
Breastfeeding is the best nutrition for infants since it gives benefits not only for infants, but also for mothers. Exclusive breastfeeding makes infants have better growth and development. WHO recommends six months of exclusive breatfeeding, which is breastfeeding without food or other drinks. One of the obstacles for exclusive breatfeeding is of the infants grandmother. Hence, specific materials for educating mothers and grandmothers on breastfeeding is needed. We developed a module for educating exclusive breastfeeding for the mothers and grandmothers by the 4-D method (define-design-develop-disseminate). The findings showed that the module could be used by health cadres to address issues related to exclusive breastfeeding among mothers and grandmothers.

Abstract
This research aims to determine the effect of disaster risk perception on disaster preparedness for families on the coast of Sumur district, Pandeglang, Banten. Participants in this research are families who live in coastal area consisting of father or mother in each family. Total respondents were 174 people, all of whom were victims of Banten tsunami. The measuring tool used in this research is the disaster risk perception that will be measured using the Risk Perception Belief for Disaster measurement tool that was used in the National Health Survey Risk Perception (NSHRP) in 2012 and further developed by Yong (2017). Disaster preparedness will be measured using instruments based on the grievances that have been put forward by Indonesian Institute of Sciences (LIPI) and Unesco regarding disaster preparedness. This research approach is a quantitative approach using the test of influence. The results found that there is positive influence between disaster risk perception on disaster preparedness on families in the coastal Sumur district (F = 28.23; p = 0.000 <0.05). The effect of Disaster Risk Perception on Disaster Preparedness is 14.1%. There is a significant influence between the disaster risk perception to disaster preparedness on the family in the coast of Sumur District, Pandeglang. If the disaster risk perception is high, the disaster preparedness will also increase. The implications of the results of this research are research subjects who have a high disaster risk perception, meaning that the community has the value of trust that the place they live has a risk of natural disasters and finally feels they have high responsibility, control, acceptance and response to disaster risk, so that this will encourage the community to be able to carry out disaster preparedness.

Abstract
Dryland is potential to increase migration, social structure damage, low productivity, limited economic growth, and marginalization without any support and assistance and East Manggarai Regency is one of the areas with those possibilities. The purpose of this article is to scrutinize the management of dryland farming in supporting the necessities of life in food-insecure areas. This research belongs to descriptive analytical study and applies survey technique. The samples were taken using purposive sampling technique. A total of 80 respondents took part in this research; they were from four villages in two selected food-insecure sub-districts, namely Borong and Komba. Effective dryland farming management is highly relevant to the supply of food and raw materials. The management in the studied areas mostly applies minimum inputs and leads to commercialization. Land tenure is used for the production of staple food and plantation crops. Staple food crop yields are used to ensure the availability of staple food, while plantation yields are used to meet other necessities. Limited transportation infrastructure contributes to less optimum potential for the development of staple food and plantation crops.

Abstract
Heavy metal pollution has spread through many parts of the world, especially developing countries such as Indonesia. Large quantities of hazardous chemicals especially heavy metals have been released into environment worldwide due to global rapid population growth and intensive domestic activities, as well as expanding industrial and agricultural production. Environment in urban areas have also been associated with water and soil quality problems because of the practice of discharging of untreated domestic and industrial waste into the water bodies which leads to the increase in the level of metals in river water. Based on that, the study of heavy metal pollution is needed to evaluates the water and soil pollution levels in areas suspected of being polluted and quantifies the risks of pollutants pose to human health. To assess these potential threat levels, the environmental indices will be applied, along with the US Environmental Protection Agency (USEPA) recommended method for health risk assessment. The results will demonstrate not only the severity of heavy metal pollution from the study areas, but also the high carcinogenic and non-carcinogenic risks that environment heavymetal pollution poses to the public, especially to children and those living in the vicinity of heavily polluted areas.

Abstract
Treatment of wastewater in fish ponds is an effort to reduce the impact of pollutants contained in the wastewater so that it can be disposed into the aquatic environment safely. The purpose of this study is to understand and analyze the effect of inoculant sources on removing of total ammonium in vanamae shrimp and marguensis shrimp pond wastewater, and to pre-design the technology for treating high-salinity organic waste with biological wastewater treatment using natural microorganisms. The study was conducted using a laboratory scale reactor. At the beginning of the study, adherent biofilm media was planted at the bottom of the sea with a depth of 1.5 m for 3 weeks in order to grow nitrifying bacteria, then applied to treat pond wastewater. The results showed that the efficiency of ammonium reduction with adherent media from Telukawur is 74% while adherent media from Panjang Island is 66% with declining and fluctuating trends every day. The large -scale application for treating wastewater from brackish water aquaculture is designed with 4 processing units, a 15.5 m x 7.7 m x 1.5 m sedimentation basin, a 10.5 m x 3.5 m x 1.5 m anaerobic basin, a 13 m x 13 m x 1.5 m aerobic basin, and a 15.5 m x 7.7 m x 1.5 m effluent basin. It can be concluded that biofilm adhesion technology from Panjang Island waters and Telukawur waters can work efficiently in removing ammonium concentration.

The sedimentation control have been made include the disposal of sediments that settle in the reservoir by dredging or flushing. However, the results are not optimal. This is caused by the large volume of sediment entering the reservoir each year. Controlling volume of sediment that goes into the reservoir have also been carried out by conducting a watershed conservation program and building checkdam in the upstream Mrica reservoir. However, the existing checkdam is still less effective in controlling sediments, especially suspended load sediments, that are transported in the river. Therefore this study was carried out by adopting the sediment trap concept to deposit sediments that escaped from checkdam. This study simulated changes in the width of the downstream channel of checkdam by three variations using HEC-RAS. There were width of 20%, 40% and 60% wider than initial width. The results showed the effect of changing the channel width on sediment concentration and volume sediment deposited. Based on the results of the study, the change in width to wider than the initial width could increase volume sediment deposited and decrease sediment concentration.

Abstract
Diversification of the use of spent battery is needed to increase community participation in the management of hazardous waste by re-utilizing the spent battery component and processing its to increase economic value and use it into other products. The component of spent battery that can be used again are its carbon rods and electrolyte paste, which are as an electrode for the process of purifying water, processing waste, supercapacitors as energy storage or reverse electrodialysis power generation. One of the important criteria in electrode selection is electric conductivity, besides porosity and surface area of particles. Hight electrical conductivity will make it easier for electrons to flow, while large porosity and outer surfaces will increase the conversion of ions into electrons in the electrodes. The aim of this study is to find out the best electric conductivity from mixing carbon rods and electrolyte paste spent batteries in carbon electrode application. The carbon rods spent bateray contained 94% carbon and the electrolyte paste of spent battery contained 64% Carbon, 19% Zinc and 5% Manganese. Before mixing, carbon rods were made powder with ballmils for 4 hours and produced with a size of <250 nm as much as 6% and 84% measuring up to 1 micrometer (1.000 nm). Carbon powder and electrolyte paste were mixed in a ratio of 9:0, 8:1, 7:2, 6.5:2.5 and by adding 10% PVDF and NMP as binders. The ingredients are mixed to form a gel then printed with the pressing and immersion method. The electric conductivity is measure by LCR meter and BET are use to measure porosity and surface area of the particles. The best electric conductivity is obtained from a mixture of carbon rod and electrolyte paste in a ratio of 7:2 with an electric conductivity value of as much as 2.7543 S/Cm, the porosity is 0.028 cc/gr and surface area is 15.936 m2/gr

Abstract
Dimembe Village which is the capital of Dimembe Subdistrict, North Minahasa Regency has been famous for a long time as a center for export quality papaya production. However, since the beginning of 2016 the price of papaya has dropped making farmers choose not to pick papaya fruit in the garden because the cost of picking and loading is not comparable to the selling price. Priority problems experienced by most farmer groups in this village are: nursery, planting, and maintenance technology are still conventional, the limitations of modern farming tools for land management, limited knowledge and skills related to fertilizing and controlling plant pests, and many other problems. To answer these problems, the community service program, Program Pemberdayaan Masyarakat Unggulan Perguruan Tinggi (PPMUPT) scheme has been carried out in 2019 (the first year, from a 3 year plan). The method of conducting the activities includes: technology dissemination, training, application, and mentoring for papaya cultivation. The application of science and technology in this program includes: land management, seed and plant preparation, fertilizing, maintaining, controlling plant pests, and harvesting. The results of the implementation show that PPMUPT activities in the first year have a positive impact on society includes: improving the quality of governance and socio-economics of community, improving moral and character, and improving conservation of natural resources.

Abstract
This research was conducted to evaluate particulate matter 10 (PM10) concentrations in ambient air of West Sumatra Province during rainy season, i.e., in March 2018. Data from four sampling locations were collected. The first one was collected from an air quality monitoring station (AQMS) located at a roadside in the office of West Sumatra Governor. The other locations represent industrial area, i.e., nearby a cement production plant, a campus area that is located nearby an agricultural area, and a background concentration area that is considered unaffected by anthropogenic sources. The measurement results show that the highest PM10 was obtained nearby the cement industry area which was 68.71±10.99 µg/Nm3. This value exceeded World Health Organization (WHO) threshold for 24-hour measurement, although it is still below the Indonesian National Ambient Air Quality Standard (NAAQS). On the other hand, the rest locations still met both WHO and Indonesian NAAQ Standards, i.e. 13.20±3.11, 28.60±13.97, and 33.85±8.41 µg/Nm3, at the background concentration location, Governor-s Office, and the campus area, PM10 concentrations were, respectively.
