Abstract
One form of development activities carried out by humans is the exploitation of natural materials energy. Often the activity of exploiting natural material energy is only oriented to human interests, but ignores aspects of sovereignty (autonomy) of nature and the future of members of the local community of exploitation place. This paper shows field observations and literature reviews on the practice of energy exploitation of natural materials in Eastern Indonesia, which lacks attention to the dimensions of the balance of nature and the interests of local communities. Eastern Indonesia has not prospered because it is still struggling to obtain their sovereignty in the exploitation of natural materials in their own land. Often social conflicts arise due to the exploitation of material energy carried out. The research method uses interpretative analysis and philosophical reflection to get meaning. Research found a theoretical model that is useful for overcoming the problem of exploitation that occurs. Those humans must transform themselves into ecological human beings so that they can bring practical benefits to the good of nature and East Indonesia local people towards the vision of sustainable development.

Abstract
Sulawesi and Maluku islands are tectonically under a collision area of four earth crust plates, those are Eurasia, Philiphine Islands, Pacific Ocean and Australian-India Ocean. Palu city in Central Sulawesi island in particular is geologically an area of complex structure. A fault zone of north-west to south-east direction has formed Palu area as a block being squized by Palu-Koro strike-slip fault zone. The earthquake happened on October 28, 2018 has caused the fault to activate of being dynamic movement of the area. Rock and soil slide and movement was also strengthened by liquifaction of hydrological fluid content within the Palu block. Morphology of Palu-Koro fault plane was also affected siginificantly causing land slides and slumps on the fault plane exposed in the earth surface. Using hand camera photos, a morphological survey and analysis show the landslides and slumps could be clearly identified.

Abstract
Increasing human activity leads to increased concentrations of greenhouse gases in the atmosphere, especially carbon dioxide (CO2) and methane (CH4) that impact climate change and global warming. This condition encourages the occurrence of weather anomaly phenomena in the atmosphere such as rainfall fluctuations, dryness, increase in air temperature and sea-level rise. Sea-level rise was a potency of seawater inundation that gave an impact on land degradation. The study aimed to determine sea-level rise used three variables of disaster with two cumulative scenarios. The toward step used the simulation using a raster calculator in ArcGIS 10.2 to analyze the impact of sea-level rise to inundation disaster. The results showed that the sea-level rise on the South Coast of Yogyakarta based on (1) Scenario 1A (existing) were 1.4457 m (the prediction year 2030) and 2.0827 m (the prediction year 2050). According to the scenario (2) 1B (extreme) is 1.6297 m (the prediction year 2030) and 2.2667 m (the prediction year 2050). The increase in the sea-level rise on the south coast of Yogyakarta provides a disaster effect of inundation in the area directly dealing the beach and near the river mouth for example in Bantul Regency and Kulon Progo Regency.

Abstract
Sedimentation at coastal city of Cirebon is caused by considerable abration process in Indramayu regency and the impact of sand mining on Gosong Island, Indramayu Regency, beside that, the habit of residents in coastal city of Cirebon who heap up garbage at the coastal for years to utilize the area for residential purpose also contributed significantly the problem of sedimentation in the coastal area of Cirebon City. This research applying remote sensing technology of Landsat 7 2005, 2007, 2010, and 2015 using Lemigas Algorithm to gain information of special and temporal increase of sedimentation, distribution pattern, and density level of sedimentation. The result shows that accretion of sedimentation process between 2005 and 2015 at Lemahwungkuk Subdistrict is 56,989 Ha with a sedimentation rate of 5,699 Ha/year. Kejaksan Subdistrict has increase sedimentation by 16,491 Ha with a sedimentation rate of 1,649 Ha/year. The most significant increase happened at 2010 to 2015, with 46,072 Ha. However, from 2005 to 2010 the sedimentation increased by 5,675 Ha. There are 2 types of distribution pattern at Cirebon City, the first one is the sedimentation that ends in the estuary of river, particularly at Sukalila and Kesunean River deltas. The other type is the sedimentation caused by the presence of longshore currents which carry sediment and stuck on the coast along coastal city of Cirebon. Identification of natural and artificial sedimentation is carried out based on surveys in the field. The Lemigas Algorithm used only for classification of sedimentation (natural and artificial) based on density level of sedimentation content (mg/L).

Abstract
Environmental damage that has occurred in Indonesia has severely disrupted public health. Many efforts have been made to improve the environment, both technically and non-technically. But these efforts did not show significant positive results. This condition shows that there needs to be a breakthrough in the form of innovations, especially in terms of technology to prevent and control of environmental damage. This study aims to investigate the potential for innovation in the field of environment that was generated by Indonesias young generation. In addition, this research also portrays the innovation ideas that want to be realized as well as obstacles in realizing them. The method used in this study was the distribution of questionnaires to 78 respondents randomly and a review of secondary data. The results of the study show that innovations to improve environmental conditions are not solely by making pollution control devices, but also innovations related to the use of environmentally friendly energy, organic food, waste recycling, saving natural resources, and innovations that can change the behavior of people as polluter. The results of the questionnaire dissemination also showed that only 50% of respondents felt the support of the Indonesian Government towards innovation development programs. The biggest obstacle for respondents in realizing innovation is limitation in funding and ability to start invention management. Therefore, the most needed activity is training on how to develop ideas into innovations and potential funding that can realize these innovations. The young generation of Indonesia represented by the respondents in this study stated that copyright to an innovation outcome is valuable. As many as 76% of respondents interested in applying license for their innovations in the form of patents or copyrights.

Abstract
The inhibitory potential of plants during early succession is crucial but little appreciated. Negative effects of these species can slow, arrest, or deflect succession. Aggressive invaders suppress plantings or nurse plants suppress desired target species. Such an inhibitory effect often causes problems during restoration. Study aggressive invaders would assist in informing ecological restoration. Here, line transects was used to investigate species composition and its characteristic on seven coal mine overburden dumping site in tropical climate. There are 124 plant species invaded coal mine overburden on early succession, and 70 of them are classified as invasive species, such as Acacia mangium, Chromolaena odorata, Centrosoma pubescens, Micania micrantha, Imperata cylindrica, and Lantana camara. Acacia mangium and Centrosoma pubescens which are widely planted for reclamation purposes on ex-coal mine area categorized invasive species. The negative impact of these species on inhibition of succession has been seen in certain location. Therefore, understanding the nature of species can facilitate the development of target species for accelerating succession.

Abstract
The research purpose is to find out about neutralization, coagulation and filtration processes in peat water. Water is an environmental component that has a considerable role and the requirements in terms of quality and quantity. The presence of water in peatland areas is less profitable, because peat water is surface water from peat soil with striking features because it is brownish red in color, contains high organic matter, tastes sour, pH 2-5 and has a low hardness level. This research method uses experimental design and the variables are the processes of neutralization, coagulation, and filtration of peat water. Descriptive statistical analysis is an analysis carried out to assess the characteristics of a data. The results of the research were from the initial test obtained pH = 4.32. There are some changes from all parameters starting from dark black water color (1088 PtCo) to 179 PtCo, high turbidity (13.2 NTU to 6.55 NTU, high iron content (1.68 mg / l) to 0.26 mg / l, high chromium (0.093) mg / l to 0.023 mg / l), low acidity (pH) (4.32) to pH 5.57 and high sulphate (744 mg / l) to 24 mg / l.

Abstract
Corn farmers on dry land tend to use inorganic fertilizers in excessive amounts to increase corn production without considering the right dosage and the application method. To obtain the right dosage and the better application method, a study has been conducted to investigate two packages of fertilizer doses and placement methods which were tested on dry land of Dompu, Indonesia. Research to test the three types of fertilizers (Nitrogen, Phosphorus and Potassium) in corn was tested in five sub-district locations in Dompu (1 ha in each location), namely Huu, Pajo, Woja, Kempo, and Manggalewa sub-districts. There were two fertilization packages tested in this study; (1) Urea 300 kg/ha and PONSKA 300 kg/ha given 2 times by row placement, and (2) Urea 300 kg/ha and PONSKA 400 kg/ha given 1 time by broadcasting. The results showed that the first package of treatment produced significantly higher dry weight of corn seeds (12.26 tons/ha) compared to the second package (7.98 tons/ha). In addition, the leaves of the corn plant in the first package treatment were still green at the time of harvest which can be a source of animal feed, compared to plants in the second fertilizing package that have dried and are brown in color.

Abstract
Food processing needs to pay attention to health principles so that the food produced is not only nutritious but also healthy and safe to eat. Healthy food should not harm the body. For that the application of sanitation and hygiene is an absolute thing in the implementation of food by a food handler. One form of the application of the principle of hygiene sanitation is personal hygiene behavior. The importance of this is related as an effort to prevent contamination of food. The researcher wanted to know the personal hygiene behavior of Vocational School students during cooking practices. The study used a cross sectional design with desktiptif analysis. Data collection is done by observation. Respondents were 161 students of the School of Culinary Vocational School in Bandung Raya, namely SMKN 9 Bandung, SMK 3 Cimahi, Baleendah 2 Vocational High School and SMK IT Nurul Imam. The results of the study revealed that there are 13 indicators of personal hygiene behavior practices that must be applied by students when cooking. The practice that should receive more attention is to get used to always washing hands properly before and after touching food. In addition, an attempt to refrain from talking too much when processing food. The use of double bress, headgear and apron has been carried out mostly well. While the habit of using nect tie needs to be increased so that it becomes an important concern for students.

Abstract
Situ Parigi is located in Parigi Lama Village, Pondok Aren District, South Tangerang City. Based on the water quality measurements of Situ Parigi, BOD parameter has the highest concentration. This indicates that the type of waste that enters this water body is dominated by organic waste produced from domestic activities around it. The purpose of this study is to determine the pollutant load capacity of BOD in Situ Parigi. Pollutant load capacity is calculated using formulas in Minister of Environment Regulation No. 28 of 2009 concerning Capacity of Lake Water Pollution and/or Reservoir Load. Situ Parigi has an area of 4 Ha, an average depth of 0.98 m, a debit of 0.023 m3/sec and a hydraulic residence time of 18.25 days. Based on the calculations results, the pollutant load capacity of Situ Parigi is 3,169.81 kg/year but must accommodate a load of 20,553.15 kg/year. These results show that the pollution that occurs in Situ Parigi has exceeded its capacity.

Abstract
Research has been carried out on measuring metal content and predicting the volume of leachate produced from Muara Fajar Landfill in Pekanbaru from 2019 to 2024. Measurement of metal content was carried out to determine the amount of metal concentrations contained in the leachate at this time, whereas the prediction of leachate was carried out to determine the growth of leachate volume every year until 2024. Metal content was measured using the Atomic Adsorption Spectrometer (AAS) and leachate volume prediction was done by using a dynamic system model using powersim. Based on the measurement of metal content, it is known that there is a leachate pond that has a metal content value exceeding the threshold of 6.4517 mg/l. While based on the results of the predicted growth in the volume of leachate, it shows that each year the volume of leachate increases by 35.44% or an average increase of 5,467.5 mg/l until 2024. A scenario was made as an effort to control metal content in the leachate collection pond, namely by photoremediation using Cyperus papyrus and Echinodorus palaefolius plants. Scenarios were performed to calculate the number of plants needed so that the metal content is reduced and does not exceed the quality standard threshold. The calculation results reveal that 12,173 Cyperus papyrus plants or 10,348 stems of Echinodorus palaefolius plants are needed to reduce metal content by 30%.

Abstract
This research aims to know the waste cassava peels is cleaned for glucose levels that will be used as raw material for fermentation process through bioethanol. Cassava peels contain lignosellulosic which consist of 43% cellulose, 38% hemicellulose, and 19% lignin. This research process is done in two stages, namely the process of pretreatment/delignification and hydrolysis. Delignification is done by making use of Aspergillus fumigatusi in Potato Dextrose Broth medium and performed a cassava peels is cleaned up to size 40 mesh. Pretreatment uses the variation comparison of fungi against raw material of 1:1, 1:3, 1:5 and the contact time of 1, 3, and 5 days. The analysis stage pretreatment using Chesson method.

Abstract
In Indonesia, especially in urban area such as Jakarta, it is very common that greywater generated from households run off into drainage system. The greywater that mixed together with rain water will flow onto river. Increasing population means increasing in households as well as greywater generated, that become serious problem when greywater becomes dominant in drainage system. To minimize the pollution from greywater in river stream, it was used the constructed wetland with subsurface system in riverbanks of Ciliwung river. The research was conducted using the vetiver (Vetiveria zizanioides) planted in the subsurface-constructed wetland to decrease the parameter of ammonia and phosphate from greywater. The aim of the research is to determine the removal efficiency of the parameters from greywater using the wetland located in Srengseng Sawah subdistrict, South Jakarta City. With the residence time of 2 days, the parameter of ammonia could removed 70% while for phosphate parameter is 65%. To reach the quality standards, it is suggested to add the pre-treatment of aeration for the wetland.

Abstract
This research purpose to remove copper heavy metal (Cu2+) with a biotechnological approach using mixed microalgae Chlorella sorokiniana, Monoraphidium sp. and Scenedesmus obliquus which is bound in Na-Alginate polymer. The effect of contact time and temperature on the biosorption rate was examined to achieve the greatest efficiency in the Cu2+ metal removal process. Bonded biosorbents are made by drying in an oven, grinding, and trapping into polymer alginate to form immobilized microalgae or called beads. The decrease in Cu concentration was analyzed using Atomic Absorption Spectroscopy (AAS). The absorption properties of biosorbents were characterized using Fourrier Transform Infrared (FTIR) and Scaning Electron Microscopy (SEM). Optimization of absorption parameters was carried out in a batch system using a concentration of 20 mg/L Cu wastewater, biosorbent concentration 0.5 g/g, pH 4 with contact time setting (60, 120, 180) minutes and temperature regulation (25, 30, 35)oC. The results showed that maximum biosorption occurred at pH 4, temperature 30oC and contact time 120 minutes with removal efficiency 82%. This research prove that immobilized microalgae is very effective for reducing Cu2+ in wastewater, and immobilized microalgae could act as biosorbents which are effective in further optimization.

Abstract
Skipjack tuna is one pelagic fish that always migrates for a condition with relevant oceanographic factors for their survival, particularly for optimum sea surface temperature and chlorophyll-a. This study conducted with the experimental fishing method from June - November 2018 in the waters of Ternate Island in observation of the optimal condition of oceanographic factors, mainly SST and Chlorophyll-a in the distribution of skipjack tuna. Employing a polynomial regression analysis, the research results show that the sea surface temperature and chlorophyll-a parameters are strictly related to the distribution of the amount of skipjack tuna caught with correlation coefficient value (r) respectively of 0.646 for sea surface temperature and 0.565 for chlorophyll-a. The optimum temperature for the skipjack tuna in the waters of Ternate Island according to the research results ranges from 27.0oC - 30.9oC, while the optimum condition of chlorophyll-a is higher than 0.2 mg/m3-0.35mg/m3, and it seems that every increment of chlorophyll-a content in water indicates an increase of the amount of skipjack tuna catch.
