Abstract
Under normal operating conditions nuclear facilities have potential release of radioactive substances into water bodies. Radionuclide release to the environment is very complex that it needs to be simplified with a mathematical model approach using Surface Water Modeling Systems (SMS 10.1) that resolves hydrodynamic differential equations by finite element method. In river, pollutant dispersion is strongly influenced by the process of advection and diffusion, where the advection process becomes more dominant. The goal of this research is to model the dispersion of 60Co radionuclides in Cisalak River located around Serpong Nuclear Area. In this research, the simulation is done by the hydrodynamic model simulation using Resources Management Associates (RMA2) module to model the flow and continued using RMA4 to model the dispersion of pollutants. In addition, this research uses discharge values variations for the dry and rainy seasons. The 60Co concentration at the release source is the highest, lowest, and average value in the last three years. The results shown that the dispersion pattern of 60Co concentration along Cisalak River is a function of distance and time. In addition, the concentration of pollutants is strongly influenced by river characteristics and also discharge of the river and effluent.

Abstract
This study aims to obtain empirical data on the model of social engineering of elderly fishermen in improving the quality of local life. The study used qualitative methods, from May to November 2017 in Pantai Bahagia Village, Muara Gembong District, Bekasi Regency, West Java. The results of the study show that: (1) The various strategies adopted by elderly fishermen in fulfilling their daily needs and their application in daily life are highly dependent on various socio-cultural factors and the possible strategies that can be developed. The main strategies carried out in the elderly at the research site include: intensification strategies, job diversification strategies, and strategies for utilizing social relations. (2) An intensification strategy is a pattern of operating a business tool (boat are used as business capital) by involving boys. (3) Diversification strategy is a pattern of additional work besides being a daily fisherman, such as working as a fish seller outside the village, a camera repairman, or a fisherman worker. And (4) The strategy of utilizing social relations, is a pattern that is not directly related to service, but still has influence in the social and cultural fields such as social works, as well as guardians of the tomb.

Abstract
Soil organic matter (SOM) has a very vital role in determining soil fertility status and land productivity. The amount of SOM in the soil varies greatly depending on land use and land management. This study aims to describe the SOMs status in various land uses and management, and to test the accuracy of near infrared (NIR) technology in measuring the SOM. A total of 100 soil samples (0-10 cm depth) were collected from various land uses and management (rain-fed land, irrigated land, land planted 1-3 times with annual crops, land planted with 1-3 perennial plants) in Kayangan Sub-District, North Lombok. The dried, ground and sieved soil samples were divided into 2 parts; some parts were analyzed using the Walkley and Black method, and the other parts were scanned using near infrared spectroscopy (NIRS). Partial least square regression (PLSR) was used to create a SOM prediction model. The results showed that the SOM content varied from very low to moderate. The content of SOM was significantly higher in the irrigated areas compared to the rain-fed areas. The SOM content was higher in the areas planted with annual crops 3 times a year compared to the areas planted 1-2 times a year. In addition, SOM content was higher in areas planted with 2-3 types of perennial plants, compared to those planted with 1 type of perennial plants. However, the SOM content was not significantly different in the area planted with annual and perennial plants. NIRS technology was relatively accurate in measuring SOM, which was compared with conventional (Walkley and Black) method. Thus, this technology can be used to monitor spatially changes in SOM. With the relatively low SOM in various land uses in the study area, the addition of SOM through fertilization is recommended.

Abstract
Many studies encourage destinations to consider dispersal and mobility as key strategic components of tourism planning and development. Essential aspects such as destinations visited, the arrival and exit directions become a basis for formulating a tourism planning policy. However, research in examining this paradigm by using a spatial analysis is limited. This paper introduces an analysis by using Geographic Information Systems (GIS) to create a visualization of tourist dispersal and mobility. This methodology was implemented in the Great Ocean Road Region, an iconic regional destination in Australia that is experiencing a limited tourist dispersal. Results from 351 questionnaires were processed by GIS with a web-based application. The data process uses tools, including ArcGIS ESRI to create spatial data and PHP and JavaScript programming languages to visualize the results. The results show that there is a low geographical dispersal in the region with the hinterland area remains untapped while the coastal area receives abundant of tourists. It is aggravated by limited tourist mobility which arrives and exit from the same direction. With GIS technology, the visualization from this spatial analysis shows a possible tourism pressure that is worth-noted by policy-makers in the planning and development process.

Abstract
Bio-remediation is one technique to reduce environmental pollution and renew soil with the help of microorganisms and plants. The process carried out includes detoxification of toxic chemicals by cleaning the environment naturally and economically. This study aims to identify waste recycling, modification of ecology-based farming systems, and test traditional plants as a source of bioremediation. Then, bacteria and bioremediation results will be used as liquid fertilizer. Liquid fertilizers are processed through bioremediation techniques, then reused as nutrients for organic cosmetics plants. The research method is carried out qualitatively and its application is in a polluted environment. The research findings state that there is a positive impact on reducing environmental pollution, especially in reducing the volume of waste and the smell of garbage. Meanwhile, the success of bio-remediation in liquid fertilizer depends on the Hydrogen (H2) cycle. In addition to H2, there are carbon (C), sulfur (S), and nitrogen (N) during the bio-remediation process which encourages the bio-remediation of liquid organic fertilizer to be able to fertilize the plant source of organic cosmetics. Thus, cosmetics can be said to be organic as a whole.

Abstract
Four kinds of fruit waste in Blora and Tuban , Java island, still have calorific values which could be harvested as a daily house hold energy source after they turn to charcoals. A small scale carbonization furnace needs to be desiged to fullfill this purpose. This research purposes to test an impact of carbonization period to the yield of secang, roda, ketapang and siwalan (skin) fruit charcoals using PEM A-HRV furnace. The furnace was designed only for 4(four) kg in capasity to minimize emission during carbonization. The carbonization temperature was set at 400 oC with the optimum carbonization period of 4(four) hours in the maximum furnace capasity. A natural draft inlet oxygen system was used for carbonization. The charcoal yielded was between 21.77 % to 32.57 % weight averaged from the 17 times tests. The Calorific values of charcoals vary from 5240 cal/gram to 6490 cal/gram adb depending on the type of the fruit charcoal. The volatile matter content was still more than 20 % weight adb in average, saying that the temperature for carbonization need to be increased eventhought this may decrease the charcoal yield.

Abstract
This paper aims to determine the effect of waste management on the reduction of greenhouse gases that relies on end-of-pipe disposal elements. The analysis of this study uses the application of dynamic systems. This study places that the waste management system is not in accordance with the growth of the volume of waste generated, the availability of resources, and environmental conditions in certain social areas and the increase in gas emissions will continue to increase along with the increase in the volume of waste. Therefore, by using a quantitative approach, it is concluded that in general the waste is hoarded openly (open dumping), does not follow the rules of sanitary landfills, there is no gas collection and processing system so that it pollutes the atmosphere, and the absence of leachate collection and processing systems results in soil pollution and Surface water. Greenhouse Gas (GHG) emissions from the waste sector can be reduced by implementing waste treatment by recycling. Waste recycling has been carried out by the community and by the City of Sanitation and Landscaping Office (DKP) of Malang City by increasing its capacity, GHG emissions can be reduced by 85.15% of GHG emissions in the initial conditions.

Abstract
Waste is still a problem that disturbs the community, waste consists of several types, including solid waste in and liquid waste. Liquid waste can be produced from the results of household activities, this liquid waste is in the form of oil, sauce and soup leftovers, etc. This liquid waste will be discarded along with soap waste through a drainage system which if it is discarded to the ground , it has the potential to cause damage. The purpose of this study is to develop a method to reduce the negative impact of these household wastes. The method in this study was a quasi experiment that will measure the quality of wastewater before and after being processed with tools made by researchers. The measuring instrument used TDS meter. The results show that water treated with the first filter is more effective than the second and the third filters. The composition of the first filter consists of peble, sponge, cloth, pool filter. The differences between the first filter and the second/third filter is that fine and coarse sawdust were added in the second and third filter. After being tested it turns out that sawdust actually contributes to increase the level of pollution in the wastewater.

Abstract
Wastewater is commonly reused in agriculture in many agricultural countries such as Indonesia. However, this condition leads to various health and environmental issues. In previous studies, Moringa oleifera seeds provably found to be a strong natural coagulant and disinfectant. Yet, its ability to improve the effluents for the leachate treatment in constructed wetland is still unknown. This study aims to investigate the effect of Moringa oleifera seeds in reducing several effluent parameters of landfill leachate from constructed wetland. There was no prior treatment before discharging landfill leachate into subsurface flow constructed wetlands and flew it into flocculation coagulation process using Moringa oleifera seeds. The parameters studied were organic substances (BOD and COD), heavy metals (Cr and Pb) and coliform to determine the efficiency. Result indicated that using Canna indica in constructed wetland followed by Moringa oleifera seeds as flocculation coagulation had more than 85% removal efficiency in all parameters. Although it showed adequately high in the efficiency, the standard sets for bacteriological substance for effluent parameters are yet fulfilled. Therefore, further researches especially by combining Moringa oleifera seeds with other coagulants are necessarily conducted in order to meet the expected requirements.

Abstract
The purpose of this study was to analyze the "social map" related to the relationship between exposure to environmental news and curiosity over issues of environmental damage together with the behavior of rejecting non-environmentally friendly products. The study was conducted in December 2018 - January 2019 in held at the Antara TV News Agency. This study uses survey methods and correlation techniques. The results of this study indicate that: (1) There is a positive relationship between exposure to environmental news and rejection behavior of non-environmentally friendly products. Socially, if the news relating to the positive environment will form a rejection of the increasingly positive community behavior towards products that are not environmentally friendly. (2) There is a positive relationship between Curiosity over Environmental Issues with product rejection behavior not environmentally friendly. Socially, if the publics curiosity about environmental issues is high, the behavior of rejecting non-environmentally friendly products also increases.

Abstract
Bekasi is a district that borders directly with Jakarta, Road and Environment Network is a strategic infrastructure as a link between the nodes of activity. Large administrative areas, sporadic centers of activity become a common problem in the area of district. As a result, the integration of the road and environment network and authority matter become a problem in the development of the district. The urban area in Bekasi district covers seven subdistricts, namely: Central Cikarang, South Cikarang, North Cikarang, West Cikarang, East Cikarang, South Tambun, and Cibitung. Within those urban areas, the integration and authority of the road and environment network become a problem. The aim of this research is to make an inventory of road network condition in the urban area of Bekasi. The method of approach used is by conducting field observations, doing institutional surveys to gather the secondary data, in institution such as subdistricts, the Public Works Office, and Binamarga Office, then doing descriptive analysis and overlaying maps using ArcGis linked to the policy of Regional Spatial Planning in Bekasi district. The results of the findings are input for policies on road network development in urban areas of Bekasi district.

Abstract
Situ Gede is a natural water body located in Kelapa Indah, Tangerang District, Tangerang City, which has an area of 5.07 hectares. The decrease in water quality is characterized by the number of pollutants such as pollutants BOD (Biochemical Oxygen Demand), which are closely related to human activities such as the disposal by organic waste from domestic activities around it. The purpose of this study is to analyze the self purification of water body in degrading of organic matter. The average of residence time of Situ Gede is 3.05 hours and a mixed concentration is 16.12 mg/l. The calculation results, the degradation rate at Situ Gede is 0.19/day. These results are stated as the composition of BOD in the Situ Gede situation not degraded perfectly. Alternative strategies for water pollution control can be done by entering oxygen in the transition will help the growth of aerobic microorganisms for the process of reforming organic matter.

Abstract
Nitrogen (N) is a vital macro nutrient for plant growth. The adequate amount of this nutrient in rice paddy field is one of the key factors for generating optimum plant production. However, measuring soil N using conventional analysis takes time and expensive. Most of previous researches reported that near infrared spectroscopy (NIRS), which is rapid and inexpensive method, is able to successfully predict soil N due to its high correlation with soil carbon (C). The aim of this research is to test the ability of NIR technology to predict soil N content which is independently predicted from soil C of rice paddy field. Soil samples in 147 locations, including the coordinates, were collected from rice paddy field of Lombok Island, Indonesia. Parts of the samples were analysed in a laboratory using conventional analysis for total N and organic C, and other parts were scanned using near infrared spectroscopy (NIRS) for spectral data collection. A Partial Least Square Regression (PLSR) calibration model was developed using laboratory-analysed soil N (and C) data and soil spectral data. As the soil N and soil C have a poor correlation, but both can be predicted well using NIR technology, this means that the soil N was independently predicted from soil C using NIR technology. This shows that the NIR technology can be rapidly used to measure both soil total N and organic C, although both of them have low correlation.

Abstract
In response to the diminishing availability of fossil energy sources, many countries have increased the use of renewable energy, especially wind energy. The application of wind turbines is often in conflict with landowners/users, especially the tourism sector, which is one of the emerging industries throughout the world including Indonesia. Whereas, most tourists who travel in Indonesia aim to enjoy natural beauty. This study analyzes the attitudes of tourists on the application of wind turbines in coastal tourism objects, by comparing how the visual impact in the installation of wind turbines whose different levels of beauty will affect their attitude. Quantitative methods through questionnaires and. Sampling with simple random sampling technique is used in this study. The results show that tourists will tend not to visit coastal attractions if there are wind turbine installations. They argue that wind turbines threaten the nature of the tourism industry.

Abstract
Banana peels waste contains lignocellulose which can be converted into starch and then broken down into glucose which will produce bioethanol. This study aims to reduce organic waste and determine the enzymatic activity of Aspergillus fumigatus fungi on banana skin enzymatic hydrolysis in the manufacture of bioethanol. The process starts from delignification followed by the hydrolysis process using a chemical catalyst, H₂SO₄ as a comparison and biological catalyst namely Aspergillus fumigatus. The study showed that the hydrolysis process was successfully carried out using a biological catalyst at a temperature of 30°C and a contact time of 3 days. During the hydrolysis process, the starch content was 3% - 4% using the DNS method. This shows that the use of banana peels waste containing lignocellulose can be used as a source of bioethanol which aims to reduce organic waste.
