Abstract
The Government of Indonesia (GoI) has committed to reduce Greenhouse Gas (GHG) emissions by encouraging the acceleration program for battery-based electric motorized vehicles for road transportation through a Presidential Regulation Number 55 of 2019. To accelerate the number of Battery Electric Vehicles (EV), supporting infrastructure is needed such as charging stations. Because with the availability of a sufficient number of charging stations, it will be one of the attractions for people to buy Battery Electric Vehicles. By using the System Dynamics methodology, a projected modeling of the number of Battery Electric Vehicles and Charging Stations (CS) is made until 2030. The increase in the number of Battery Electric Vehicles is influenced by, among others, the price of Battery Electric Vehicles and also the number of Charging Stations themselves. The projection results state that the ratio of the number of charging stations to the number of Battery Electric Vehicles is still far below 1:10. So that the increase in the number of Battery Electric Vehicles must be further improved by lowering the price of Battery Electric Vehicles, one of them.

Abstract
In 2019, Indonesia has installed about 2.13 GW of geothermal and made it the second largest country utilizing geothermal. However, the capacity is less than 10% of the total potential and far from the target of 9.3 GW in 2030. A challenge in geothermal development is the environmental issue where more than 50% of the potential is located in conservation and protected forests. Recently, a regulation has been issued allowing geothermal development in those areas. A study to design a model of the forest area management for geothermal development was carried out in the Mount Ciremai National Park by identifying inventorying and evaluating the changes in forest zone utilization. There are three approaches applied in the study: ecology, social, and technical designs. The forest area management model was developed through stages, i.e., clustering of forest utilization and analysis of ecosystem, social activity, and area management alternatives. It is recommended that areas should be avoided are the core zone of the national park, nature preserve, areas that are indicated as important flora and fauna habitats, primary forests, and steeply sloped areas. It is about 1,369 Ha of the area that can be used for geothermal development.

Abstract
Lab-scale constructed floating wetlands (CFWs) using Vetiveria zizanioides and Heliconia psittacorum in a batch mode system was studied to treat textile effluent. The CFW unit (size of 1.8 m x 0.6 m (LxW)) was made with palm fiber media wrapped in the fish net and tied to the PVC pipe frame. Two CFW units were each planted with V. zizanioides, and H. psittacorum, and one CFW unit was without plants as control treatment. Then all CFW units were placed in each microfiber cell with dimensions of 2 m x 0.98 m x 0.60 m (LxWxH). The performance of CFWs was examined for about 21 days with 20 and 50% textile effluent. V. zizanioides and H. psittacorum for both 20% and 50% textile effluent showed good performance in removing ammonia with removal efficiency (RE) ranging from 60 - 80%. Reasonable RE was observed for TN but not for TP and phosphate. The study suggests that both V. zizanioides and H. psittacorum could be potential plants used in the CFW system to treat textile effluent.

Abstract
Integrated farming maximizes revenue from existing resources and increase the benefits of interconnection between business branches, namely vegetables and cattle in the form of increased production yields and reduced production costs. Suboptimal land problems occur due to deficient rainfall so the existence of an embung (small reservoir) as a water provider becomes very important. This study describes the integrated farming system of cattle, vegetables, and embung to increase farm efficiency and farmer income. The material used in this study is embung in the size of 15x40x4 m, 12 tails of cattle for breeding activities, chili plants in size of 600 m2, eggplant in altitude of 600 m2, solid organic fertilizer, and liquid organic fertilizer. Analysis financial of Revenue Cost Ratio was used in the assessment. Financial analysis was carried out on non-organic fertilized and organic fertilizedplants. The average income of each commodity was calculated to determine the total farm income of the integrated activity of vegetables, cattle, and embung. The results showed that farming activities on dry land carried out in integrated farming between plants (vegetables) and cattle provide benefits with an R/C ratio in number of 4,0 for the use organic fertilizer and 2,0 for the use non organic fertilizer. Water from Embung can save of cost up to 13,000,000. With these considerations, integrated farming activities on dry land which was supported by the availability of embung have big potential to be sustainable.

Abstract
Bangka Belitung as an archipelagic province has abundant marine natural resources, including tin reserves and mariculture potential, one of which is Matras waters, Bangka Regency. The exploitation of tin mining in coastal areas will have an impact especially decrease the fish abudance at sea. Therefore, this research was carried out to producing the management blueprint of these two activities in the term of sustainability. The methodologies used in this research are analysis of hydro-oceanographic characteristics, sea water quality conditions and the suitability of mariculture on April 2022. Based on the field data, the quality of sea water in Matras waters can be classified as still quite good where only TSS has a value below the sea water quality standard. However, if we look at the aspect of aquaculture suitability, Matras waters still have the potency for mariculture especially at stations 1 and 2 with suitability scores reaching 76 and 78 which are classified as moderately suitable. In addition, if we look at the legal-socio-economy aspect, clear regulations are needed from the government, both central and regional in managing marine utilization areas such as tightening the implementation of the Approval for the Conformity of Marine Spatial Utilization Activities (PKKPRL).

Published: November 2022

Abstract
The problem of slope stability is an important issue because it concerns human safety issues, equipment, buildings and disrupts the smoothness of production. In this research we hope can anticipated failure damage wich interpertation probability of failure. To analyze the stability of the slope can be known through the mechanical properties such as cohesion, friction angle and unit weight of the rock with Point Estimated Method [1] in 3 time standart deviation.The large FK does not represent a more stable slope, because the uncertainty of slope is not captured by the FK value. The slope with FK = 3 does not mean 2 times more stable than FK 1.5 then it is used the probability of sliding formed from some mechanical parameters. Based on the analytic calculation using point estimate method obtained the probability of failure (POF) plane of 0,00004%. Based on the Stacey table (2009) then POF plane 0,00004% can still be accepted.

Authors: Yofianti D , Safitri R 
Published: November 2022

Abstract
Environmental damage that occurs is generally caused by human activities. The activities carried out lead to mobilities with a tendency to a certain pattern. During the Covid-19 Pandemic, the Indonesian government issued a policy of restricting the human mobility to reduce the spread of the Covid-19 virus. The reduced human mobility in mining activities may lessen the level of environmental damage that occurs. Therefore, this study aims to determine the effect of human mobility restrictions during the Covid-19 pandemic on the level of environmental damage that has occurred. Pangkalpinang City was taken as the location for data collection in this study. Data collection will be undertaken by distributing questionnaires online to people who live in the research location. From the results of the questionnaire, human mobility patterns will be mapped to the activities conducted and the level of environmental damage that has occurred. The results of this study can show the distribution of human mobility patterns to environmental damage that occurred due to policies to restrict human movement during Covid-19 Pandemic.
