Abstract

In a wireless cooperative network, system reliability can be improved by introducing network coding (NC) for transmitting data packets from user to destination through relay nodes. At the destination, a decoding strategy is required to recover the original data packets. The use of NC in cooperative networks has been intensively studied in previous works in terms of the conventional model for two users and a single relay in a network. However, the network model cannot act as a virtual multiple-input multiple-output system, and a multi-user multi-relay network model could be used in a real system. Therefore, this paper proposes an improved model of two network decoding strategies, selection with soft combining (SSC) and selection with hard combining (SHC), for multi-user multi-relay cooperative networks. Users are classified based on their channel conditions, with better signal-to-noise (SNR) ratio sources being viewed as strong users, and others as weak or moderate users in the decoding strategies. To evaluate the performance of the proposed model, we first derive the bit error probability expressions for each strategy as a function of SNR and then evaluate the performance using numerical simulation for a Rayleigh fading channel. Simulation results show that SSC outperforms SHC. Furthermore, the improvement in network performance is achieved either by having a higher modulation level or using incremental relaying as the signal reception method at the destination.

Abstract

This study aims to identify and describe Implementation of Building Service Permit Policy (IMB) at the Office of Investment and Service Integrated One Door DPM-PTSP Sigi District. The author uses the theory of George C. Edward III which includes factors Communications, Resources, Disposition, and Bureaucratic Structure. The type of research is using qualitative descriptive methodology. Based on the acquisition shows that the implementation of government policy in licensing service especially the building permit service (IMB) in Sigi Regency has not fully run well and has not had a positive impact on development. This is evidenced from the four aspects studied, has not supported the factors proposed by Edward III is related to communication factors, resource factors and disposition factors. Can be explained that not maximally Implementation of Government Policy in licensing service specially Permit to construct building in Sub-Province of Sigi which impact on execution of comprehensive development in Sigi Regency. This can be seen from the number of people taking care of the IMB is very less. Only bureaucratic structural factors are eligible to implement the policy but also have not shown significant positive impacts so that the priority of development success programs has not been achieved, including giving serious attention to the success of policy implementation especially in terms of licensing service in Sigi Regency.

Abstract

A study of relationship between state and religion includes three paradigms: integralistic, symbiotic, and secularistic, which are products of legal reasoning to Quranic messages in the context of human history. In the case of Indonesia, it embraces Pancasila, which is neither based on religious nor secular systems. However, muslim communities in Indonesia become political targets due to the factors which include the weakness of Islamic politics that is uprooted from Islamic fundamental values in terms of political aspirations, and the application of western democracy that is not compatible with the traditions and cultures of Indonesia.Kata Kunci: pemikiran Islam, Negara, agama

Abstract

In Islam, marriage is sacred. Thus, the procedures of a marriage and of a divorce are arranged in Islam. One of the Islamic regulations on divorce is  ta’lik talak. Ta’lik talak in Islamic law is a marital contract declared by a husband in marriage through which a divorce will occur when the husband breaks the contract. In the Compilation of Islamic Law in Indonesia, we also find the so-called marital contract that has some similarities and differences from ta’lik talak. Ta’lik talak and marital contract can be done and can be a reason for executing a divorce when it is violated by the husband. However, ta’lik talak cannot be canceled as long as the marriage is intact. This is not the case with the marital contract where it can be canceled based on the agreement of the two (husband and wife), in spite of their intact marriage. Kata Kunci: Ta’lik talak, fikih, perjanjian perkawinan, Kompilasi   Hukum Islam

Abstract

ABSTRAK Sistem komunikasi kooperatif device-to-device (D2D) merupakan salah satu strategi peningkatan kecepatan data dan efisiensi energi. Pada sistem kooperatif, mekanisme relay merupakan faktor penting dalam meneruskan informasi. Model jaringan merupakan isu penting untuk meningkatkan kecepatan, kinerja dan efisiensi energi pada sistem. Oleh sebab itu, makalah ini menganalisis kinerja jaringan hybrid kooperatif D2D pada teknologi 5G menggunakan teknik pemilihan relay reaktif atau reactive relay selection (RRS). Beberapa parameter kinerja penting telah simulasikan, seperti model jaringan, SNR, BER dan throughput. Hasil simulasi menunjukkan bahwa jaringan kooperatif hybrid-relay dengan RRS menghasilkan nilai BER yang lebih kecil dan throughput yang lebih tinggi dibandingkan model multi-relay dan multi-hop relay. Dengan demikian, jaringan hybrid-relay dengan pemilihan relay lebih efisien dibandingkan jaringan lainnya. Kata kunci: sistem komunikasi kooperatif, pemilihan relay reaktif, multi-hop, multi-relay, hybrid-relay. ABSTRACT A device-to-device (D2D) cooperative communication system is one of the strategies to increase data speed and energy efficiency. In a cooperative system, the relay mechanism is an important factor in forwarding information. A network model is an important issue to increase the speed, performance and energy efficiency of the system. Therefore, this paper analyzes the performance of D2D cooperative hybrid networks on 5G technology using reactive relay selection (RRS) techniques. Some important performance parameters have been simulated, such as network models, SNR, BER and throughput. Simulation results show that hybridrelay cooperative networks with RRS produce smaller BER values and higher throughput compared to multi-relay and multi-hop relay models. Thus, hybridrelay networks with relay selection are more efficient than other networks. Keywords: cooperative communication system, reactive relay selection, multihop, multi-relay, hybrid-relay.
