Abstract

BACKGROUNDA hidden Markov model (HMM) is used for exon prediction on DNA of genes Plasmodium falciparum that has a model structure based on exon region structure in coding sequence (CDS). The objective research was to develop a new structure model to predict exon on DNA-genes of Plasmodium falciparum based on CDS structure using the HMM system.METHODSModel design in CDS, between two exon regions can be found one intron region and the model state number is used for its region. Its state number is used by separating start codon from first exon region and stop codon from the last exon region up to 9. The Viterbi algorithm and the backward-forward method for transition as well as emission states are used for training process. Furthermore, Viterbi and Baum-Welch algorithms are used for the testing process. The correlation coefficient (CC) was used as performance indicator, as the ratio of the estimated state in the output and the original state in the input of the model. RESULTSThe simulation results has shown that the CC values depend on the given of the backward-forward transition state values randomly. The model with state number 9 showed the highest average of CC values of 0.7289 for Viterbi algorithm, and is 0.7166 for Baum-Welch algorithm. However, the lowest average of CC values has been found for the model with state number five. Its values are 0.6735 by using Viterbi algorithm and 0.6661 by using Baum-Welch algorithm. CONCLUSIONThe new structure model based on HMM system was valid to predict exon on DNA-genes of Plasmodium falciparum.

Abstract

Abstrak – Jurnal ini mengkaji kawasan Samudera Hindia yang menjadi arena kompetisi India dan China. Kompetisi berawal dari tiga kebijakan China yaitu, Counter Piracy Operation, string of pearls  dan projeksi politik luar negeri belt and road inisiative China yang menjadi faktor penyebab India bereaksi. Reaksi India (act east policy) menciptakan situasi dilema keamanan, salah satu contoh kompetisinya adalah memperkuat pertahanan di pangkalan militer Andaman dan Nicobar yang berbatasan langsung dengan teritori Indonesia (Aceh) untuk memantau intensitas mobilitas PLA Navy China di Selat Malaka. Letak geografis yang strategis (sebagai choke point), membuat Indonesia memiliki peran natural dalam kompetisi India dan China. Sehingga Indonesia perlu menyikapi kompetisi dengan cara meningkatkan hubungan yang kooperatif antara India–Indonesia–China. Untuk mendukung penelitian ini penggunaan teori neo realis, dilema keamanan, dan geopolitik berfungsi menganalisis dinamika kompetisi. Kemudian teori politik luar negeri bebas aktif dalam kerangka Poros Maritim Dunia dan diplomasi pertahanan berfungsi sebagai landasan Indonesia bersikap. Penelitian dilakukan dengan pendekatan kualitatif yang mengandalkan data tinjauan pustaka dan wawancara. Hasil analisis bertujuan sebagai rekomendasi kebijakan pemerintah Indonesia yang selaras dengan kepentingan nasional Indonesia dalam menyikapi kompetisi India dan China di masa depan.Kata Kunci : Dilema Keamanan, Kompetisi India China, Samudera Hindia, Diplomasi Pertahanan Indonesia Abstract – This journal is about competition of India and China in Indian Ocean Rim. Causes of the competition are from three policies of China, first Counter Piracy Operation, second string of pearls  and third belt and road inisiative China. Reaction of India (act east policy) automaticaly make a security dilema situastions, e.g of the competition is strengthening India far base military in Andaman and Nicobar island is facing to Indonesian territory (Aceh) to monitoring PLA Navy intensity through Mallaca Strait. Indonesia with choke point, make Indonesia have a natural role in the competition of India and China. Then Indonesia have a right to respond the competition with increasing cooperative relations between India – Indonesia – China. Journal analisys are using neorilsm, security dilema, and gheopilitic. Then free active foreign policy in maritime exis framwork and defence diplomacy are base of Indonesia responds. Qualitatif will bring this reasearch and use data base from any litteratures and interviews. The purpose of analisys results are for policy recomendation that relevan with Indonesia national Interest to respond India and China competition in the future.Keywords : security dillema, india China Competition,  Indian Ocean, Defence Diplomacy of Indonesia.

Abstract

Abstrak -- Implementasi kebijakan kerja sama program KFX/IFX mengalami penundaan dikarenakan adanya kendala pada ketersediaan anggaran pertahanan. Meskipun telah dilakukan evaluasi, program harus tetap dilanjutkan karena menyangkut pencapaian kepentingan nasional di bidang pertahanan pertahanan udara. Oleh karena itu, terdapat dua rumusan masalah yang diangkat dalam penelitian ini, yakni bagaimanakah kepentingan Indonesia dalam kerja sama program KFX/IFX Indonesia-Korea Selatan? dan bagaimanakah peran diplomasi pertahanan terhadap implementasi kebijakan kerja sama program KFX/IFX Indonesia-Korea Selatan, khususnya dalam melancarkan program tersebut yang sempat tertunda?.Penelitian ini dilakukan dengan menggunakan pendekatan kualitatif. Data dihimpun melalui proses wawancara dengan informan dari berbagai Kementerian/Lembaga terkait. Kemudian didukung dengan studi literatur. Proses analisis data di dalam penelitian ini dilakukan dengan membandingkan lima teori dan konsep yang digunakan, yaitu peran, kepentingan nasional, strategi, negosiasi internasional dan diplomasi pertahanan. Hasil penelitian menunjukkan bahwa kepentingan Indonesia dalam program ini melibatkan banyak sektor pada Kementerian/Lembaga nasional. Sehingga, dalam upaya memenuhi tujuan akhir kemandirian pertahanan nasional maka setiap sektor tersebut memiliki andil dalam menentukan aspek-aspek yang akan dinegosiasikan ulang terhadap pihak Korea Selatan. Dengan demikian, bentuk diplomasi pertahanan Indonesia dalam upaya melanjutkan program kerja sama KFX/IFX adalah dengan membentuk Tim Renegosiasi. Tim Renegosiasi bertugas sebagai aktor dalam upaya menjalankan diplomasi terhadap DAPA, JPMO dan KAI. Tim terdiri dari K/L dan konsultan hukum serta industri yang berperan secara tertutup dalam merumuskan aspek-aspek yang perlu direnegosiasi, kemudian peran terbuka untuk secara langsung melakukan diplomasi terhadap pihak Korea Selatan.Kata Kunci: peran, diplomasi, program KFX/IFX, tim renegosiasi, kepentingan nasional Abstract -- The policy implementation in KFX/IFX cooperation programme has been delayed due to the problem in defense budget availability. However, after the evaluation to the programme has been done. It conclude that the programme shall be continued in case to achieve the national interest of defense sector through Minimum Essential Force fulfillment, specifically in air defence. Therefore, there are two research question appear in this research. Firstly, how is the national interest of Indonesia in KFX/IFX cooperation between Indonesia-Republic of Korea, specifically in purpose to reinforce the delayed programme and how is the role of defense diplomacy in policy implementation of KFX/IFX cooperation programme Indonesia-Republic of Korea .This research used qualitative approach. Data has been collected through interview process with informants from various related Ministry/Institution. The research then supported by literature study. The process od data anlaysis in this research has been done with comparing the five used theories and concepts, which are Role, National Interest, Strategy, International Negotiation and Defense Diplomacy. The result showed that national interest of Indonesia in this programme involves many sectors in Ministry/Institution. Therefore, in the effort to fulfil the goalof the independency of national defense industry, so every sector has their own contribution on determining the aspects of renegotiation with Republic of Korea’s side. Finally, the form of Indonesia’s defense diplomacy in continuing KFX/IFX cooperation programme is by building a renegotiation team. Renegotiation team is in charge as an actor for committing diplomacy action with DAPA, JPMO and KAI as RoK representative. The team consists of related Ministry/Institution, Law and Industry consultant. It played part as covert role in constructing the renegotiations aspects, yet as overt role in holding the diplomacy way to the Korean side.

Abstract

In this paper, the problem of subcarrier allocation on chunk-by-chunk basis in SC-FDMA uplink systems is investigated. Improved mean enhanced greedy algorithms are proposed for performing joint-user and chunk-based allocation at each transmission time interval. Selection criteria based on spectral efficiency and fairness are also proposed to choose the final allocation at each transmission time interval. Simulation results show that when the number of users and the velocity of the users were varied, the improved algorithms that use selection criteria based on spectral efficiency and fairness could outperform the existing mean greedy algorithms that employ user-based allocation in terms of spectral efficiency and fairness. Moreover, the improved algorithms not only showed better performance but also had the same time complexity as the existing mean greedy algorithms.
