The Helsinki MoU agreement gave birth to Law Number 11 of 2006 concerning the Government of Aceh. In Article 171 Paragraph (1) of Law Number 11 of 2006 it states, "The Aceh Government and district/city Governments have the authority to determine land allotment/spatial use for development purposes guided by statutory regulations." spatial use of Aceh directs spatial use of Aceh in a harmonious, balanced, integrated, sustainable and environmentally sound manner and is based on the philosophy of life and cultural wisdom of the Acehnese people. The philosophy of life and cultural wisdom of the people of Aceh are inseparable from Islamic values.

Privileges are special powers to carry out religious life, custom, education, and the role of the clergy in establishing regional policies. Therefore, the field of spatial planning in Aceh can be based on Islamic values. According to Islam, spatial planning in the environment is to improve the welfare of the people, maintain environmental sustainability and harmony, which has a strong nuance of Islamic values. Spatial planning seeks to provide efficiency and improve the quality of life, because the human task is to prosper the earth (land) of Allah SWT, not to destroy it.

This research approach is a normative juridical approach or also known as a doctrinal approach or normative legal research. Legal research data sources can be in the form of primary legal materials, secondary legal materials, and non-legal materials. Data collection techniques through a statutory approach. After the existence of the Aceh Qanun concerning the 2013-2033 RTRWA, the Aceh spatial planning no longer revives the mukim mosque and meunasah as the center of community activities. However, the Aceh Province has introduced Islamic values ​​in spatial planning through Asmaul Husna pamphlets along roads in North Aceh and East Aceh, as well as around the fence of the Aceh Governor's Hall. Likewise with the existence of prayer rooms in every hotel and shopping center. Naming the names of Government Agencies and Shops with Jajo Arabic script.

Even though Aceh's spatial planning is not strictly based on Islamic values, for example gyms such as gyms do not yet show Islamic values, that is, men and women are still mixed. As well as in shopping centers there are no special places for women to breastfeed. Through the revision of the Aceh RTRW which can be done once every five years, so that later a truly Islamic-based spatial planning is realized, this is so that it is in accordance with the vision and mission of the Aceh RTRW to create prosperous Acehnese people in accordance with the needs and lives of the Acehnese people.

We see an increasing demand for user-defined security service in mobile networks
and the trendis to deploy IT based services in a mobile-edge cloud in the future.
However, it lacks a flexibleand efficient architecture to provide dynamically changing
security services for different users in themobile-edge cloud. To address this problem,
we purpose an architecture of mobile-edge stateful securityservice chaining, which
achieves a scalable combination of various required security functions.In addition, we
present the stateful service function proxy, aiming to support compatibility to
traditionalsecurity functions and convert them into stateful functions to shorten the
transmission time ofpackets. Much work has been done to implement the proof-of-concept
testbed of the architecture,and experimental results verify its feasibility. Moreover,
we compare the performance of the proxy inthe stateful mode with that in the stateless
mode, and the result proves that the proxy running in thestateful mode can significantly
decrease the transmission time of packets and improve the forwardingefficiency.

Wireless Mesh Network, holding the features of self-organization, strong
scalability, low deploymentcost, is considered to be the most competitive technology for
broadband wireless access service.However, the security and privacy issues become the
bottleneck for WMN’s rapid popularization.Network coding, which can improve both network
throughput and anonymity, is adopted for thecommunication security in WMN recently.
However, the related network-coding based anonymouscommunication schemes suffer from the
efficiency and security issues. In this paper, an efficientanonymous communication
scheme for WMN is proposed, which combines the opportunistic routingprotocol and network
coding approach. The global coding vector is protected with the lightweightpermutation
encryption mechanism. In addition, the security and performance analysis demonstratethat
the proposed scheme can provide strong privacy protection for WMN communication with

In recent years, many institutes and organizations have been made efforts into
developing new networkarchitecture. Universal Identifier Network(UIN) is one of them
which is designed to providebetter mobility, better security and better reliability.
Multicast is the basic network layer service thatis designed to save bandwidth for the
whole network. The deployment of existing multicast schemeis restricted because of low
security and the lack of control in sources. In this paper we have designeda
central-controllable and secure multicast(CCSM) system for UIN that aims to achieve
bettersecurity and scalability. We design the group management protocol and multicast
routing protocol.The former one restricts the group members’ joining with authentication
and the latter one provides asecure way to install multicast entries on routers. We
evaluate CCSM by comparing it with PIM-SM,and the results show that CCSM is more secure
and reduces the multicast flow entries for the wholenetwork.

As the number of mobile devices used in everyday life increases, interest in
wireless charging technologyfor continuous use anytime and anywhere is increasing. The
existing wireless chargingmethod transmits power to all mobile devices within the
transmission distance, which causes unauthorizedusers to gain access to the service,
thus causing security problems. Therefore, a technologyfor verifying the usage right to
filter unauthorized users is emerging as a main technology of wirelesscharging
technology. In this paper, we propose the security requirements for verifying the
authorityof the wireless charging users based on the requirements for providing the
resources to the authorizedusers and the technical research for transmitting the power
to the existing wireless communicationmethod. Considering the moving target defense
technology, we designed and implemented a doublefrequency-hopping based wireless
charging system for COTS mobile devices, based on the securityrequirements.

The non-technical loss caused by electricity theft on the user side not only
increases the operationcost of the smart grid but also causes some harm to the
electricity system. At present, the existingelectricity theft detection model ignores
the time-series correlation of user power consumption data,and the distribution of
positive and negative samples in the relevant data sets is uneven. Aiming atthe existing
problems, we propose an electricity theft detection model based on Borderline-SMOTEand
WDCBL(wide and deep CBL) networks. The WDCBL model consists of wide componentsand deep
CBL components. The wide part uses a fully connected layer to extract
one-dimensionalfeatures in user electricity consumption data. The model introduces the
hybrid network model ofa one-dimensional convolutional neural network(CNN) and
bidirectional long-term and short-termmemory network(BiLSTM) into the deep part, which
can learn both spatial and temporal features inuser electricity consumption data.
Finally, we conducted a comparative experiment on the user electricityconsumption data
published by SGCC. The results show that our model is superior to othersin the
comprehensive performance.
