Abstract
Cinangka Village has been the center of the accu smelting industry since 1980. This has resulted in soil contamination. The purpose of this study is Analyzing the effectiveness of Ornamental plant (Cordyline fruicosa) and Land cress (Ipomea reptans Poir) in reducing Pb on the soil. The method used for sampling is purposive sampling. The parameters tested were total Pb in soil and % Pb in plants also the dry weight of the plants. The effectiveness of the plants is known by calculating the difference of total Pb in soil with total Pb absorbed from plants divided with total Pb in soil and multiplied it with 100%. The experiment were using Ornamental plant (Cordyline fruicosa) and Land cress (Ipomea reptans Poir) within 24 and 36 days to remediate the soil with 157,82 ppm and 10032,84 ppm Pb. The highest level effectiveness of lead phytoremediation with plants was with Land cress with an average of 0,994% within 24 days of Pb polluted soil of 157.82 ppm. The effectiveness of lead phytoremediation with the lowest plants was Ornamental plant with an average of 0.945% within 36 days in Pb polluted soil of 10032,84 ppm. The Effectiveness of phytoremediation treatment with Orrnamental plant and Land cress in one harvesting is not effective (Less than 1%) in reducing lead concentration in the soil.

Abstract
Mining is a rapid process of topographical change, the former sand mining area is a complex problem between the legal aspects of land ownership, environment, geohydrology, technology and socio-economic. The former sand mining area is quite extensive in the area along the Cisadane River which includes Tangerang Regency and Bogor Regency, for proper management of the area, a study needs to be carried out in the form of identifying the condition of the former sand mining quarry. This study aims to identify ex-mine pit and the complexity of problems in the management plan of the former sand mining area. This study was carried out only by evaluating published map maps and field observations from aspects of geology, geohydrology and environment. In the study area there were 112 holes in the sand excavation hole, 57 in the Bogor district and 55 holes in the Tangerang Regency with a range of 0.9 to 9.4 ha. The former sand hole is always filled with water so it becomes a lake or it is never dry because this mining exploits sand in the form of aquifer sand. From the existing holes there is no one who reclaims according to good and correct mining rules. Utilization of former excavation holes is relatively not optimal, only 1 is used as a source of rural clean water. Mapping of former sand mining areas is absolutely necessary for sustainable planning and management of environmentally sound management.

Abstract
An eruption of Mount Kelud dated February 13, 2014 at 2 2. 5 0 WIB spewed 150 million cubic meters of material, which is said to be the largest eruption history since the last 100 years, in fact did not result in casualties, in three affected districts (Blitar, Kediri, Malang). Even though at that time the transition status from PVMBG occurred relatively short (less than one month). Based on information from the Center for Volcanology and Geological Disaster Mitigation (PVMBG), an increase in seismic activity was observed since January 2014, which was dominated by Shallow Volcanic (VB) and Deep Volcanic (VA) earthquakes. Based on seismic activity, the status of the Kelud volcano was then raised from normal to vigilant on February 2, 2014 , although the situation was considered to be less than ideal in rescuing, but the community was able to evacuate independently quickly at the right time and to the right location. In fact there were no fatalities or zero victim in the 2014 eruption incident. This study was designed to determine the role of Kelud Kelangkar Community in building the resilience of the people living in the vicinity of Kelud Volcano (Blitar Regency, Kediri Regency, and Malang Regency), in the phase, pre and post eruption of the Kelud Volcano in 2014 . The type of research used is descriptive research with a qualitative approach. A qualitative approach is a research procedure that produces descriptive data in the form of words written or spoken of - people and behaviors that can be observed. The object of the research was conducted at the Kelud Anchor Community in the Kelud Volcano area (Blitar, Kediri and Malang Regencies). Communities have been selected at the time of the eruption of Kelud Volcano T a hun 2014, were able to participate in community mobilization inside Kelud Volcano KRB and has been able to menyiapsiagakan themselves in the face of Gungungapi Kelud eruption, as well as the survivors were able to evacuate independently In this research, an in-depth description is obtained resilience of people living around Mount Kelud (Blitar Regency, Kediri Regency, and Malang Regency) in the face of the potential threat of the Mount Kelud Eruption disaster , and the Kelud Anchor Community Community in building the resilience of people living around Mount Kelud (Blitar Regency, Kediri Regency, and Malang Regency), pre and after the eruption of Mount Kelud in 2014

Abstract
The geology of Menoreh Hills is mainly developed by volcanic rocks, formed in the tertiary era, comprising Kaligesing and Dukuh formations. Overlaying these formations, there are beded limestones of Sentolo Formation, and alluvial deposits. The volcanic rocks consist of andesite pyroclastic breccia, tuffaceous breccia, and lava, as well as laharic breccia and andesite intrusion, generally subjected to quite intensive joint expansion. There are also some lateral slip faults with a general pattern of Northwest - Southeast and Northeast - Southwest. Most of the lithology especially volcanic rocks in the Menoreh Hills are undergone very extensive weathering, forming soil with a thickness of up to 5 meters. The mechanical properties of fresh volcanic rocks, described in the value of friction angle () ranges 40o – 65o, cohesion force (c) 15 kg/cm2 – 40 kg/cm2, while  of the soil ranges 3o – 24o , with c = 2.5 kg/cm2 – 8 kg/cm2. The geological setting and rock mechanical properties of the Menoreh Hills bring about specific characteristics of landslides. General characteristic of slope failures in the Menoreh Hills is involving soil or debri, saturated water conditions,  value less than 25o, slope inclination greater than 20o (36%), and soil thickness more than 3 meters. On the other hand, the model of landslides of Menoreh Hills can be grouped into three types consisting of rotational mass movement, soilslide through the boundary plane between fresh and weathered rocks, and wedges failure with joint intersections act as the sliding plane.

Abstract
Tides and abrasions as the impact of climate change pose serious risks to coastal communities in Brebes Regency. The coastal communities of Brebes Regency have social capital for disaster risk reduction as a form of disaster adaptation and mitigation strategies. Social capital in disaster management is an effort to improve emergency preparedness and respond to the disaster recovery and reconstruction process. The objective of this research is to analyze the social capital of coastal area societies in the effort of disaster mitigation as the result of climate change into three social capital (bonding, bridging, linking). The respondents are the societies who join disaster care association in Kaliwlingi, Sawojajar, and Karangdempel Village, Brebes Subdistrict. The research result indicates that bonding social capital of Kaliwlingi, Sawojajar, and Karangdempel Village is seen from trust, norms, knowledge, awareness, social activities numbers and routine, participation, basic facility and individual-s characteristics. However, Karangdempel and Sawojajar village has lower social activities, participation, and awareness than Kaliwlingi Village. The bridging social capital in Kaliwlingi, Sawojajar, and Karangdempel Village can be seen fromsome groups. However, Sawojajar and Kaliwlingi Village has internal problem so that it reduces the benefits of group. Linking social capital runs well in Kaliwlingi and Sawojajar village because the stakeholder moves actively. However, there is a problem which reduces linking social capital in Sawojajar and Karangdempel Village and make it nonoptimal.

Abstract
The purpose of this study was to examine the differences in constructivist learning environments in conventional and MOOC-based STEM learning. the research method uses experimental design, with a subject of 210 students of the Faculty of Mathematics and Natural Sciences in Medan, Indonesia. Data is collected through the Constructivist Learning Environment Survey (CLES) instrument. The questionnaire consisted of 34 questions consisting of six dimensions, namely - working with ideas, personal relevance, collaboration, respect for difference, critical voice and uncertainty of science. The results showed that the learning environment in the STEM class in the two STEM class groups was not significantly different. The average level of constructivist learning environment in conventional STEM is 81.14% and 79.80% for STEM based on MOOCs. Constructivist environmental dimensions in the two STEM groups, have the same sequence of outcomes with achievement levels more than 72%. The dimension with the highest achievement is “respect for difference”-, while “working with ideas” is the lowest achievement dimension. It can be concluded that the application of STEM learning both conventionally and MOOCs has similar constructive learning environment conditions.

Abstract
Kedungwaru Village is a village in Karangsambung Subdistrict located at 109 ° 3730 "- 109 ° 4500" BT and 7 ° 3000 - 7 ° 3730 LS. In the long dry season that occurs in the first half of 2018, residents in several areas of Kedungwaru Village complain of drought. Aquifers are a layer of water that can be used as a water source. The study was conducted using a single channel geoelectric instrument with the Vertical Electrical Sounding method with the aim to determine the distribution of aquifers based on the depth and thickness of the aquifer. The depth and thickness of aquifer data are then interpolated using IDW (Inverse Distance Weighted) method to produce depth maps and isopach maps. The results showed that there were two types of aquifers in Kedungwaru Village, namely unconfined aquifers and confined aquifers. The unconfined aquifer located at a depth of 1-3 m from the surface with a thickness varying up to 22 m, while the confined aquifer is at a depth of 13-30 m from the surface with thicknesses varying up to 19 m. From the acquired data, a geological model was created. Keyword: geoelectrical, aquifer, isopach, water source, Kedungwaru

Abstract
Citarum is one of the strategic rivers in Indonesia. The Citarum River Basin is the site of 3 large reservoirs that produce 5 billion kwh / year of electricity, equivalent to 16 million tons of fuel / year. Ironically, in recent years, Citarum has become the center of attention of various parties. This is because the Citarum River was named one of the dirtiest rivers in the world along with 10 other rivers in 2013. In terms of restoring the Citarum River, not only the Citarum River water needs to know its condition, but the condition of each tributary which empties into The Citarum River and the condition of groundwater around the river also need to be known. In this study, 43 samples were taken consisting of Citarum River, tributary and shallow groundwater from upstream in Situ Cisanti to Saguling Reservoir. The samples were analyzed by physical parameter test, Ion Chromatography test, and ICP-MS test. This test is carried out to test certain chemical compositions in the sample. From the results of this study it can be concluded that: 1) Generally there is a change in hydrogeochemistry conditions in the Upper Citarum area which is characterized by an increase in the number of dissolved ions in the Citarum River flow from upstream to downstream. The concentration of dissolved ions passed the threshold in almost all sampling locations, namely nitrite and fluoride. 2) The largest source of dissolved ions in the Upper Citarum area, namely the Upper Citarum (Cirasea) sub-watershed, the Cibolerang sub-watershed, and the Citepus sub-watershed. 3) Interaction Shallow ground water and river water namely ground water can pollute river water due to the process of advection and dispersion.

Abstract
Indonesia is vulnerable to natural disasters such as: earthquakes, tsunamis, volcanic eruptions, floods, landslides and droughts and forest fires. Geographically, Indonesia is also located on the equator, so this region has a tropical climate. During the rainy season when rainfall is high, this condition triggers tornadoes, floods and landslides. While in the dry season, and low rainfall occurs drought, forest and land fires. While in the transitional season, the natural phenomenon of tornadoes is a threat of disaster. In Law No. 24 of 2007 of the Republic of Indonesia concerning Disaster Management, it is stated that the central government and regional governments are responsible for implementing disaster management, with an emphasis on preparedness and mitigation in the face of natural disasters. However, socialization to the community regarding the two matters is not regulated in the existing law, so that the planning and implementation of the outreach and internalization program must be carried out to the wider community so that natural disaster preparedness and mitigation can be carried out to the maximum. In line with the development of information technology and systems that have entered the era of media convergence, namely the integration of various technology platforms on one media or equipment owned by all levels of society, the acceleration of the process of disseminating preparedness and mitigation can also be done by utilizing these equipment. Using the theory of SECI Model, the development of knowledge management can be implemented to optimize the dissemination and development of data and information about sustainable mitigation activities related to natural disasters. The results of the research are in the form of developing a Knowledge Management System (KMS) for natural disaster preparedness and mitigation that can be used to support the socialization and internalization of disaster preparedness and community-based disaster mitigation activities, including dissemination and measurement of community preparedness and mitigation performance in the face of natural disasters.
