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.

Abstract

Pendahuluan: Pemanfaatan ikan yang hanya edible portion (dapat dimakan) dapat menyebabkan terdapatnya limbah yang dihasilkan dari proses pengolahannya. Limbah sisik ikan dapat digunakan sebagai sumber kolagen. Secara umum, kolagen telah banyak diproduksi dari sisik ikan, tetapi tidak dalam ukuran nanopartikel. Partikel-partikel berukuran nano akan lebih mudah diserap dan berdifusi di kulit daripada yang berukuran makro. Tujuan penelitian ini adalah untuk menilai efektivitas nano kolagen limbah sisik ikan mas (Cyprinus carpio) untuk mempercepat waktu penyembuhan luka setelah luka insisi. Metode: Penelitian ini menggunakan true experimental laboratory dengan rancangan post-test only control-group design dengan 27 mencit jantan (Mus musculus) Swiss Webster. Perlakuan pada luka insisi dilakukan dengan penyemprotan menggunakan spray nanokolagen, spray povidone iodine, dan spray aquades. Penyembuhan luka diamati selama 7 hari setelah insisi. Hasil: Data yang diperoleh dianalisis menggunakan Uji One Way Anova, berdasarkan hasil analisis diperoleh nilai p=0,000 (p < 0,05). Hal ini menunjukkan bahwa terdapat perbedaan lama penyembuhan luka insisi antara perlakuan spray povidone iodine, spray aquades, dan spray nanokolagen sisik ikan mas. Simpulan: Nano kolagen ekstrak sisik ikan mas dapat mempercepat waktu penyembuhan luka. ABSTRACTIntroduction: The use of edible portion fish has generated waste from the manufacturing process. Fish scales can be used as collagen sources. Collagen has been produced from fish scales generally, but not in the nanoparticle size.

Abstract

OFCDM is an attractive multiple access scheme for high data rate application in Fourth-generation (4G) wireless communication system. Previously, several researches were only investigated the performance of OFCDM based on variable spreading factor. However, there are several system parameters may affected the performance of OFCDM. Therefore, this paper investigates the impact of several parameters on the performance system of OFCDMA over Rayleigh Fading channel as a realistic channel in wireless communications.The simulation system model of OFCDM is introduced. The computer simulation is developed by using MATLAB programming in order to show the impact of several parameters for OFCDM’s performance including number of carriers, size of symbol, symbol rate, bit rate, size of guard interval and spreading factor. The simulation results show that the higher number of carriers, larger size of symbol, higher symbol rate, higher bit rate and larger spreading factor are giving the better system’s performance in terms of Bit Error Rate (BER). However, the larger guard interval is giving the worst system’s performance.So all the parameters should be considered in the implementation of OFCDM for the 4G wireless communication system. DOI: http://dx.doi.org/10.11591/telkomnika.v10i3.621

Abstract

Breast cancer is a serious disease and one of the most fatal diseases in the world. Statistics show that breast cancer is the second common cancer worldwide with around two million new cases per year. Some research has been done related to breast cancer, and with the advancements of technology, breast cancer can be detected earlier by using artificial intelligence or machine learning. There are popular machine learning algorithms that can be used to predict the existence or recurrence of breast disease, for example, k-Nearest Neighbor (kNN), Naïve Bayes, and Support Vector Machine (SVM). This study aims to check the prediction of breast cancer recurrence using those three algorithms using the dataset available at the University of California, Irvine (UCI). The result shows that the kNN algorithm gives the best result in terms of accuracy to predict breast cancer recurrence.

Abstract

Perilaku konsumtif adalah perilaku individu yang dipengaruhi oleh faktor-faktor sosiologis di dalam kehidupannya yang dituntut untuk mengkonsumsi secarah berlebihan atau pemborosan dan tidak terencana terhadap barang dan jasa yang kurang atau bahkan tidak perlu. Gaya hidup konsumtif meliputi seluruh kelompok remaja termasuk mahasiswa. Seperti yang terjadi pada mahasiswa asal Toraja di Universitas Sam Ratulangi Manado yang cenderung berbelanja tanpa memperhatikan kebutuhan atau hanya untuk keinginan saja. Karena tidak semua mahasiswa berperilaku demikian, sehinggah peneliti tertarik untuk meneliti bagaimana perilaku konsumtif dan kehidupan sosial ekonomi mahasiswa asal Toraja di Universitas Sam Ratulangi Manado. Status sosial ekonomi orang tua berpengaruh pada perilaku konsumsi mahasiswa. Penelitian ini menggunakan metode kualitatif dengan pendekatan studi kasus, teknik pengumpulan data adalah observasi, wawancara, dan dokumentasi. Hasil penelitian ini diketahui bahwa mahasiswa yang mendapatkan uang saku tidak banyak akan lebih mempertimbangkan dalam berbelanja dan mengkonsumsi suatu barang sedangkan mahasiswa dengan uang saku yang lebih akan memanfaatkannya dengan sering berbelanja ketika melihat ada potongan harga, barang menarik, ataupun adanya iming-iming dari temannya. Berdasarkan hasil penelitian, maka dapat disimpulkan bahwa perilaku konsumtif terjadi karena adanya kecenderungan berbelanja yang berlebihan, adanya ketertarikan, untuk kebutuhan konsumsi setiap hari, ikut-ikutan dengan teman, adanya potongan harga, membeli barang karena trend dan untuk bersenang-senang. Keyword : Perilaku Konsumtif, Mahasiswa, Perantau
