Abstract
Plastic waste has reached a dangerous stage because it has a bad impact on life and ecosystems. Increasing numbers require treatment to reduce the widespread adverse effects. This research uses literature study to describe various alternatives of plastic waste management. To manage plastic waste, there are various steps in handling plastic waste. Principle 3R (Reuse, Reduce, and Recycle) is always applied to handle plastic waste. Recycle is an alternative today to handle the increasing amount of plastic waste, while reuse and reduce are expected to reduce the amount of plastic waste. Waste plastic recycle can be done on thermoplastic type plastics, which are plastic products / materials which can be melted again by heating to a certain temperature so that other products can be formed as desired. Plastic products that can be recycled include PET (Polyethylene Terephtalate), HDPE (High Density Polyenthylene), LDPE (Low-Density Polyenthylene), and PP (Polypropylene). Recycling for plastic waste can be done through a chemical process that is by thermal cracking / pyrolysis. Plastic that is processed by pyrolysis can convert plastic into fuel oil. With this method, two problems can be solved at once, namely the processing of plastic waste and the fulfillment of increasingly depleting energy needs.

Abstract
After hundreds of years experiencing a dormant period, Mount Sinabung erupted again in August 2010 to the last recorded in June 2018. Within eight years, significant land cover changes were seen in the area around Mount Sinabung. This study aims to analyze changes in affected areas using satellite imagery. The spatial analysis method is used to determine changes in various land cover. High-resolution images before the 2010 eruption and the latest recording images of 2019 are used as analytical material. The analysis shows that the affected area is in east-southeast and south-southeast directions of the peak of Mount Sinabung. In the east-southeast direction, the eruption material reaches 3.5 km and 4 km in the south-southeast with an area more than eleven thousand hectares. Some villages such as Bekerah, Simacem, and Suka Meriah have even been lost covered by material from the eruption of Mount Sinabung. The area is generally covered by pyroclastic materials in the form of ash, sand, lapilli, and bombs. Most of the areas affected by the eruption are plantation areas, then forest areas and settlements areas. Sinabung Eruption in recent years has had a very significant impact on various aspects, one of which is land cover.

Abstract
The number of electroplating industry in West Java in Indonesia has been increasing rapidly which influences the amount of pickling and degreasing solutions usage in the washing process. Generally the electroplating industries dump their wastewater directly to environment without any treatment. The ions of metals contained in pickling and degreasing solutions shall accumulate in the environment then finally would cause eutrofication where the water body becomes rich of dissolved ion metals which effects the dissolved oxygen contained in water body. One of wastewater treatment methods is adsorption. The activated carbon of adsorbents were applied in this investigation. Electroplating wastewater was used in order to control the ions metals concentration. The objective of this experiment was to study the removal of ion metals concentration of each adsorbent filled in adsorption column by using circulation method. The column has 2.5 inch of diameter, 100 cm of height, and 100 ml/minute of flowrate. The result of investigation showed the concentration of ions metals decrease from 745 to 521 ppm, decrease pH from 8.0 to 7.2, and decrease water conductivity from 1200 to 925.

Abstract
At present, plastic waste is one of the problems that is growing in Indonesia. Plastics take more than 400 years to degrade naturally. One way to degrade plastic waste is by biodegradation. This study aims to degrade Linear Low Density Polyethylene (LLDPE) plastic using mixed culture bacteria Pseudomonas aeruginosa and Brevibacterium sp. The research conducted using plastic cutting 1 x 1 cm in size, as much as 10 gram was put into petri dish containing Nutrient Broth (NB) growth medium. The biodegradation process is carried out for 3 months with the test parameters being temperature (⁰C) and acidity value (pH). Gravimetric and Fourier Transform Infrared (FT-IR) methods were used to determine the weight, morphology, changes in structure and surface of polyethylene. The results showed that mixed bacterial culture has the potential to degrade LLDPE plastic with a percentage reduction of 15% at 35 ⁰C for 5 days. This study proves that mixed culture of bacteria can degrade LLDPE plastic by using it as a carbon source

Abstract
The environmental crisis that hit the global world has threatened the future of the human being and all living in the world. The root of the environmental crisis today that is due because of the "human factors". Human mindset embodied in various forms of exploitation of the natural act of damaging our environment tragically. Understand anthropocentric is so permeated human thought patterns stimulate human passion to continue to exploit nature without human arbitrarily. Natural objectified and regarded as a place to suck it for the benefit of human. And nature environment needs to be protected by human as moral person. One way to protect nature is not a great design technology, but change the mind set of people from anthropocentric paradigm to eco-centrism awareness in order to protect the environment entity. Using reflection methods especially deconstruction of Derrida, continuously critical of anthropocentric is a must as one way to protect the environment in theoretical thinking frame. Through this frame of thinking, it can constructed the concept of ecological awareness for protecting environment and the good condition to the earth and all reality of life.

Abstract
Very rapid population growth, with the expansion of the industrial sector leds to increased energy demand and decreased environmental quality. One alternative to meet energy needs is to use renewable energy sources, namely biogas. Aside from being a source of energy, biogas that utilizes animal manure is also able to improve the quality of the surrounding environment to be cleaner and healthier. District of Sawangan, Magelang Regency has potential sources of biogas raw materials derived from animal manure. Recorded in the Livestock Population Report According to the Type of Livestock in Magelang Regency in 2017 by the Livestock and Fisheries Service, the number of dairy cows is 200, beef cattle are 12,633 and buffaloes are 375. With this considerable potential, researchers are trying to find out and explore information about peoples perceptions of biogas and their desire to develop and utilize biogas in their daily activities. With quantitative descriptive research methods and using Likert scale data analysis on 50 respondents, resulting that as many as 46% of respondents agreed that biogas as an alternative energy and want to have it as much as 54%. But in the statement about building biogas, most of them answered doubtfully, which is 70%. The doubts in building biogas are caused by, among others: the lack of sufficient information related to biogas, the high investment costs at the beginning of the biogas reactor construction, the useful life and function of the biogas reactor, and the availability of land as a place for biogas reactors. As a solution to these problems, IEC (Communication, Information and Education) programs can be carried out to the community especially breeders about biogas as a whole, program synergies among the government, academics and biogas developers to encourage biogas development as an alternative energy while enhancing environmental quality.

Abstract
The implementation of conservation agriculture involve minimum soil disturbance, permanent soil cover through crop residues and cover crops is good sound for improve soil fertility status and achieving higher crop productivity. A field experiment with split plots design in which conservation-soil tillage practices as main plots and beans cover crops intercropped to maize as sub plots were tested in rainfed agriculture area of South Lombok. Four soil tillage practices comprise of: P1: Direct dibbling, no tillage; P2: Soil ripping; P3: Permanent planting holes and P0: conventional intensive tillage. Beans cover crops were: C0 = no cover crop; C1 = lab-lab; C2 = cowpea; C3 = hybrid bean; C4 = Velvet bean (Mucuna sp). These were intercropped to maize as main crop. The results showed that conservation agriculture base maize with treatments of reduce tillage practices and legume cover crops improved the soil fertility including bulk density, C-org, N, P and K, and CEC. The highest soil fertility status was recorded at P3 and subsequently followed by P2 and P1. Overall, Reduced tillage practices particularly P3 with cowpea and hybrid beans as intercropped significantly increased the maize yield of 51%. Cover crop of lablab and vegetable bean have a significant effect on weight of maize fresh biomass and weight of ear, while cowpea and lablab bean have a significant effect on weight of maize dry seeds. Maize yields with CA approach average 9.95 ton per ha higher than the conventional system 7.21 ton ha-1.

Abstract
Urban societys health is directly affected by environmental factors where the quality of the environment is decided by the development of urban infrastructure. Exponential growth of population in Metropolitan Cities without being matched by basic sanitation supplies will raise the deteriorating environmental conditions. Bandung metropolitan city has a high level of urbanization so that the problem of basic sanitation supply is more important. This study aims to identify sanitation problems and efforts to improve access to basic sanitation in Bandung city. This research method uses a deductive approach with quantitative and qualitative mixed analysis methods. The use of data in this study uses secondary data from the past 5 years. Our initial synthesis shows that the main problems of access to basic sanitation in Bandung are caused by technical constraints in the form of lack of suitable land and limited access to the PDAM sewer, while non-technical constraints in the form of readiness and understanding of local urban society, and budgeting. The efforts of Bandung city are currently quite massive, but the improvement of sanitation access is still not significant.

This research was conducted to convert water hyacinth as lignocellulose-containing biomass by utilizing Aspergillus fumigatus fungi as a biocatalyst. This study began with cultivation of Aspergillus fumigatus in Potato Dextrose Broth media and preparation of water hyacinth to 100 mesh in size. Pretreatment is done by using a variation of the ratio of fungi to biomass at 1: 1, 1: 5, and 1:10 and contact times 1, 3, and 5 days. Determination of lignin as a result of pretreatment was carried out by the Chesson method. The hydrolysis stage takes place after the pretreatment stage to get fermentable sugar. The sugar content is analyzed using the DNS method. In this study, it was found that the best reduction in lignin levels after pretreatment was 38.6% and produced sugar of 12.5 g/L. A fermentation process and further research is needed to determine the potential of water hyacinth as a raw material in the production of bioethanol.

Abstract
Land Surface Temperature (LST) can be used as an indicator of measuring temperature change in the regions. The changing variation can be produced or affected by some factor such as elevation, land cover products, and Normalized Difference Vegetation Index (NDVI). This study aimed to investigate LST variation based on elevation, land cover products, and NDVI in the North Sumatra area, Indonesia. Land products satellite data between 2000 and 2018 were downloaded from Moderate Resolution Imaging Spectroradiometer (MODIS) website. Multiple linear regression was used to find the patterns of LST variation. The highest LST variation was found in Evergreen Broadedleaf (EB) forest and urban area with the average change 0.4 and 0.5 °C/decade and the lowest was found in water surface area with the average change more than -1 °C/decade. The overall mean of LST changing was -0.1 °C/decade with r-square 31.4%. There was unique LST variation in EB forest land cover when the elevation increased, the LST also increased from -0.4 to 0.5 0C/decade. The same condition also appears in Savannas and cropland/natural vegetation mosaic (Crop. Mos.). In conclusion, the changing of LST in North Sumatra was affected by elevation, land cover products, and NDVI.

Abstract
The agricultural sector is still a leading sector in Indonesia. In addition to absorbing a large enough workforce, this sector is also still able to contribute a sizeable income to the national economy. But lately there have been many changes in land conversion that will reduce the economic growth of the agricultural sector. This study aims to determine the development of land conversion that occurs and economic valuation of agricultural land that supports the sustainable agriculture sector in Bogor Regency. The economic valuation method used is the cost replacement method and contingency valuation approach to the communitys willingness to pay for agricultural environmental services and the willingness of farmers to accept payments for environmental services in order to maintain agricultural land. The results show that land conversion in Bogor Regency has taken place in general with an increase in residential land area while agricultural land area has decreased. Declining agricultural land area will reduce the harvested area so that the income of the agricultural sector decreases because it needs to control the high changes in agricultural land conversion

Abstract
This study aims to determine the effect of Poly vinyl alcohol (PVA) and Soluble soybean polysaccharides (SSPS), and to characterize it (water resistance and biodegradation test). This research was done by blending (mixing) PVA, SSPS, acetic acid, and maleic anhydride. From the results of infrared spectrum analysis on plastic films showed peaks in the area 1000-1100 cm-1 which indicates the absorption of polysaccharides. This plastic has an optimum water resistance of in the ratio between 1:1 w/w (SSPS:PVA). Optimum biodegradation test results in the ratio of 1:1 w/w (SSPS:PVA). Based on the result of the research, it can be concluded that water resistance and biodegradation reach optimal on composition 1:1 w/w (SSPS:PVA).

Abstract
Rapid industrial development can lead to environmental pollution. bad air environment will cause damage to the skin such as dry skin. Indonesia has biological natural resources such as coconut trees and castor oil plants. Both oils can be used to make skin care due to the impact of heat by the environment. This study aims to determine the effectiveness of using VCO oil from coconut and castor oil in natural creams to treat dry skin. The method of this research is an experiment that is looking for the right comparison to make natural creams from each VCO oil and castor oil. The experiment was carried out on 10 dry skins of student volunteers. Research using randomized group only design is divided into two groups. Group A is the experimental unit for treatment and group B is a comparison group, subjects are selected by purposive sampling from a particular population. This study used an 8-experimental design of the initial test until the final test in both groups. The results showed that tcount > ttable is 2.441> 1.330 so Ho is rejected and HI is accepted at the 0.05 significance level. So, there are differences in the use of pure coconut oil cream (VCO) and castor oil cream to reduce the smoothness of the skin.

Abstract
Reclamation in the former mining area is a series of ongoing activities with planned post-mining activities, so that the reclamation activity plan is adjusted to the post-mining activity plan. However, a lot of ex-mining land at this time, especially abandoned tin mine in Bangka Belitung Province is not well covered so it does not meet the applicable post-mining rules. Planning for reclamation of ex-mining land that has been abandoned or that has been re-mined by the community is a challenge to represent a concrete manifestation of sustainable management in the Indonesian mining sector, which refers to Government Regulation No. 78 of 2010 and the Minister of Energy and Mineral Resources Decree No. 1827 2018. Preliminary investigation of the condition of the land to be reclaimed is done by using a "drone", so that data collection can be done quickly and can present the original condition. "Drone" equipment is equipped with the concept of photogrammetry so that the results can be used for topographic map making. Some factors that need to be considered in the reclamation of alluvial tin mining are geological hazards, hydrological, hydrogeological, re-mining and monitoring. With good data from these aspects, good engineering can be carried out to realize the reclamation of the land of the former alluvial tin mine that is sustainable.

Abstract
Environment is related to tourism as one of determinant to determine tourism destination competitiveness. Environmental determinants that can affect destination competitiveness are society, technology, culture, demographic, economy, geography, history, infrastructure, law, opponent, politics, and resources. This research aims to explain how environmental determinants take effect to destination competitiveness in Pentingsari tourism village. This research finds out that seven environmental determinants which are society, culture, economy, geography, infrastructure, opponent, and resources take effect on destination competitiveness by using nature and local value that live in Pentingsari tourism village. But some environmental determinants do not take effect in Pentingsari tourism village such as technology, demographic, history, law, and politics. Lack of nature relation is the main reason that five environmental determinants do not take effect on destination competitiveness. This research conclude that environmental determinants take effect to destination competitiveness in Pentingsari tourism village through seven determinants
