Gaps in biodiversity conservation management within the Conservation Area that are the responsibility of the central government and outside the Conservation Areas or as the Essential Ecosystems Area (EEA) which are the authority of the Regional Government, have caused various spatial conflicts between wildlife /wild plants and land management activities. Several obstacles faced by the Local Government to conduct its authority to manage (EEA), caused the number and area of EEA determined by the Local Government to be still low. At present only 703,000 ha are determined from the 67 million ha indicated by EEA. This study aims to overview biodiversity conservation policies by local governments and company perceptions in implementing conservation policies and formulate strategies for optimizing the role of Local Governments. From the results of this study, there has not been found any legal umbrella for the implementation of Law number 23/ 2014 related to the conservation of important ecosystems in the regions. This regulatory vacuum leaves the local government in a dilemma for continuing various conservation programs. By using a SWOT to the internal strategic environment and external stratetegic environment of the Environment and Forestry Service, Bengkulu Province , as well as using an analysis of company perceptions of the conservation policies regulatary , this study has been formulated a “survival strategy” through collaboration between the Central Government, Local Governments and the Private Sector to optimize the role of Local Government’s to establish EEA in the regions.Keywords: Management gaps, Essential Ecosystems Area (EEA), Conservation Areas, SWOT analysis and perception analysis

The article discusses methods for determining the hydraulic resistance of units of an accident-resistant fuel system. A detailed description of the need to create such fuel systems for modern helicopters is given. The development of such systems today is impossible without the use of the method of mathematical modeling, which allows to qualitatively solve problems arising in the design process. To obtain accurate research results, it is necessary to have a complete description of all elements and assemblies of the system. Methods for determining the hydraulic characteristics of AFS elements using the drag coefficient, reference literature and CFD codes are considered. As the investigated AFS units, a drain valve and burst fitting were studied in the article. A hydraulic calculation of these AFS elements ware performed, the simulation results are presented in the ANSYS CFX software package. Also as the calculation results of bursting fitting, the pressure distribution fields of full and static pressure, velocity and streamlines are also shown. An experimental setup for validating the results obtained using the mathematical modeling method is considered, as well as a methodology for conducting a full-scale experiment to determine the hydraulic resistance of the unit. Materials have been prepared for inclusion in a one-dimensional mathematical model of an accident-resistant fuel system.

AbstractA schematic diagram of a hydraulic drive system is provided to stabilize the speed of the working body by compensating for volumetric losses in the hydraulic motor. The diagram shows the inclusion of an originally developed self-adjusting choke whose flow rate in the inlet pressure change range tends to reverse - with increasing pressure the flow through it decreases. Dependent on the hydraulic characteristics of the hydraulic motor and the specific operating conditions.

Inconsistency Regional Regulation No.14 of 2006 about marine conservation area of the island of Biawak, Gososng, which Cendekian provides protection but in fact failed to provide protection as evidenced by dredging island sandbar and cendekian conducted PT.Pertamina UP VI Balongan INDRAMAYU. The problem in this research How Formulation Policy Act No. 10 Year 2009 on the Indonesian Tourism with the Indramayu Regional Regulation No. 14 of 2006 regarding marine conservation area of the island of Biawak, Gososng, Cendekian And How Harmonization Act No. 10 of 2009 with the Indramayu Regional Regulation No. 14 of 2006 regarding formulation Act No. 10 Year 2009 on the Indonesian Tourism with the Indramayu Regional Regulation No. 14 of 2006 about marine conservation area of the island of Biawak, Gososng, Cendekian, the purpose of this research to understand and analyze the extent to which policy The findings of the community or field of law local governments about the environmental damage done by companies or individuals are not equal accordance with regional regulations in force, nor the Law in force so that the function of law in society indramayu not fit the mandate to establish a change and justice based Formulation public corporate criminal liability.Inskonsitensi happens to local regulation No.14 of 2006 makes no harmonized with the regulations of each other so that the impact of this inskonsistensi makes the sector particularly environmental law enforcement get uncertainties that result in coastal communities Indramayau.Conclusion Harmonization of regulations of the center and regions delivering the policy formulation of the rule of law area to comply with the regulations above in order to avoid inconsistency, the occurrence of this inconsistency resulted in the rule of law and justice for the indramayu, suggestion that the government should was nearly revise regulations related area, especially the government must dare to take action to give effect to the perpetrator deterrent effect rule-based running as well as possible.
