Abstract

Penelitian ini menawarkan solusi untuk akses broadband futuristik di daerah terpencil dan pedesaan dengan pilihan: optimasi LTE; dan perkembangan jaringan pita lebar yang diasumsikan sebagai 5G. Teknologi yang digunakan pada sistem 5G masa depan ialah pemanfaatan frekuensi tinggi, UE-Specific Beamforming, dan Skema Carrier Agregation (CA). Lima klasifikasi dalam implementasi jaringan futuristik: Skenario 1, Single Carrier (SC) LTE 1,8 GHz; Skenario 2, CA LTE 1,8 GHz + 2,6 GHz; Skenario 3, SC 5G 15 GHz; Skenario 4, SC 5G 28 GHz; Skenario 5, CA LTE 1,8 GHz + 5G 15 GHz. Redaman hujan diperhitungkan demi mendapat hasil realistis. Pada wilayah Leuwidamar, Skenario 5 memiliki jumlah BS paling sedikit. Sedangkan di Panimbang, Skenario 3 dan 5 memiliki jumlah BS yang paling sedikit. Namun, jika performansi energi diperhitungkan, Skenario 3 merupakan solusi terbaik. Selanjutnya, jika kita mengimplementasikan Discontinues Transmission (DTX), Skenario 3 dapat memberi kita penghematan energi yang mengesankan, dengan masing-masing penghematan sebesar 97% dan 94% pada daerah Leuwidamar dan Panimbang. Maka, hasil studi menyarankan untuk menggunakan jaringan SC 15 GHz sebagai optimisasi jaringan prospektif masa depan di Leuwidamar dan Panimbang, menimbang tercapainya salah satu target teknis teknologi 5G, yaitu ketersediaan 50 Mbps dimana saja dan kapan saja. *****Our work compared the performance of future broadband network solutions: with Optimized LTE system; and a new enhanced Mobile Broadband (eMBB) system, in which assumed to be prospective 5G network. The proposed eMBB system implements three key-techniques: high frequency, a UE-Specific Beamforming, and Carrier Aggregation (CA). We propose five solutions: Case 1, Single Carrier (SC) LTE 1.8 GHz; Case 2, CA LTE 1.8 GHz + 2.6 GHz; Case 3, SC 5G 15 GHz; Case 4, SC 5G 28 GHz; Case 5, CA LTE 1.8 GHz + 5G 15 GHz. Rain attenuation is considered to aim realistic solution. In the remote area (Leuwidamar), the Case 5 gives the least number of BS, with only 1.6 times densification of the current network. For the rural area cases (Panimbang), it is offered by Case 3 and Case 5 with the same number of BS. However, the best solution in terms of energy performance for both areas is Case 3. With DTX implementation, Case 3 gives an impressive amount of energy saving, with 97% in Leuwidamar and 94% saving in Panimbang. Thus, provided that our assumptions about eMBB techniques are fulfilled the Single Carrier 15 GHz link network is the most efficient.

Abstract

Empirical studies confirm positive impact of the telecommunication services diffusion on economic growth. However, some other studies deny such findings. The difference in findings does not seem to affect the beliefs of policymakers that the use of information and communication technologies will provide benefits in solving many problems in their countries. This encourages policymakers to develop roadmaps of ICT development in their respective countries, including the roadmap of broadband technology. This study seeks to confirm the impact of telecommunication service diffusion on economic growth in ASEAN member countries. The number of fixed-line, mobile phone, broadband, and internet service users are selected as the representative variables of the diffusion of telecommunication services within ASEAN countries. We also include some macroeconomic indicators, such as the ratio of foreign direct investment (FDI) and the number of labor force into the econometric model. The analyzed data is in the form of panel data, a combination of cross-section data of 10 ASEAN countries and time series data in the period of 2005 to 2016. Multicollinearity test requires us to eliminate the variable of the number of internet users, because its variance inflation factor (VIF) exceeds the threshold. The final analysis on the modified model indicates that at the level of significance of 5%, only the growth of the number of fixed telephone service users is not significant in affecting economic growth in ASEAN member countries. *****Studi empiris mengonfirmasi adanya pengaruh positif antara adopsi layanan telekomunikasi di sebuah negara terhadap pertumbuhan perekonomian. Namun demikian, temuan lainnya menyangkal hal tersebut. Meskipun terjadi perbedaan temuan, pembuat kebijakan tetap percaya bahwa pemanfaatan teknologi informasi dan komunikasi akan memberikan manfaat dalam menyelesaikan banyak permasalahan di negaranya. Hal inilah yang mendorong para pembuat kebijakan berlomba-lomba menyusun peta jalan pengembangan TIK, termasuk teknologi pitalebar, di negaranya masing-masing. Studi ini berusaha mengonfirmasi pengaruh difusi layanan telekomunikasi terhadap pertumbuhan perekonomian di negara-negara anggota ASEAN. Jumlah pengguna jasa telepon tetap, telepon seluler, layanan pitalebar, dan internet dipilih sebagai variabel yang menggambarkan difusi jasa telekomunikasi di negara-negara ASEAN. Penulis juga menyertakan beberapa indikator makroekonomi, seperti rasio foreign direct investment (FDI) dan jumlah tenaga kerja ke dalam model ekonometrika yang digunakan. Data yang dianalisis berupa data panel, gabungan dari data crosssection 10 negara ASEAN dan data runtun waktu pada rentang tahun 2005 sampai dengan 2016. Hasil analisis menemukan bahwa variabel jumlah pengguna internet memiliki nilai variance inflation factor (VIF) yang melebihi ambang batas sehingga perlu dikeluarkan dari model. Hasil analisis terhadap model yang telah dimodifikasi menunjukkan bahwa pada taraf signifikansi sebesar 5%, hanya pertumbuhan jumlah pengguna jasa telepon tetap yang tidak signifikan dalam memengaruhi pertumbuhan ekonomi.

Abstract

Saat ini Indonesia dihadapkan pada permasalahan dimana lalu lintas data, termasuk OTT di dalamnya, mendominasi layanan telekomunikasi yang menyebabkan pendapatan interkoneksi semakin menurun. Padahal, biaya pemeliharaan jaringan cenderung naik. Kemunculan teknologi IP dapat memberikan keuntungan, baik terhadap Operator dalam scissor effect maupun menaikkan tingkat loyalitas pelanggannya. Namun, saat ini regulasi Interkoneksi  di Indonesia masih menggunakan Time Division Multiplexing (TDM). Oleh karena itu, diperlukan suatu rekomendasi mengenai standarisasi pengkodean dan model interkoneksi IP. Dalam penelitian ini, aspek teknis dari model interkoneksi IP dianalisis dengan menggunakan perbandingan model, yaitu Peering dan Hubbing dengan metode no-transcoding pada 6 jenis codec(G.711a, G.711u, GSM, G.723, G.729, dan G.722) dengan pemberian berbagai beban trafik, (0 Mbps, 15 Mbps, 40 Mbps, dan 72 Mbps). Hasil performansi QoS berupa delay, Mean Opinion Score, packet loss, dan throughput yang diperoleh dari hasil simulasi masing-masing model dan kombinasi codec dianalisis dengan  menggunakan server VOIP Asterisk 11 dan Microsip 3.17.3 untuk SIP phone juga Wireshark 2.2.4 dianalisis untuk mengetahui performansinya. Nilai one way delay QoS mengacu pada standar nilai pada ITU-T G.1010. Dari hasil simulasi diperoleh bahwa secara keseluruhan dengan beban trafik sampai 72 Mbps, model Peering merupakan alternatif model interkoneksi IP yang terbaik. Selain itu, penggunaan codec G729 menghasilkan performansi paling baik dengan nilai delay paling minimum dan MOS paling besar, sehingga paling direkomendasikan untuk digunakan dalam implementasi interkoneksi IP. *****Currently, Indonesia is faced with problems where data traffic including OTT dominates the telecommunications services lead to interconnection revenue declining. In the other hand, the cost of network maintenance tend to increase. The emergence of IP technology may provide benefit to the operators in handling the scissor effect and improving the level of customer’s loyalty. However, the current interconnection regulations  in Indonesia are still using TDM. Therefore, a recommendation on standardization of IP encoding and interconnection model is required. In this research, technical aspect analysis of IP interconnect model is analyzed using comparison model, that is Peering and Hubbing with no-transcoding method on 6 types of codec (G.711a, G.711u, GSM, G.723, G.729, G.722) and loading of various traffic loads (0 Mbps, 15 Mbps, 40 Mbps, 72 Mbps). The results of QoS performance (delay, Mean Opinion Score, packet loss, throughput) obtained from the simulation results of each model and combination of codec are analyzed using VOIP server Asterisk 11 and Microsip 3.17.3 for SIP phone also Wireshark 2.2.4 to assess the performance. One-way delay QoS value refers to the standard in ITU-T G.1010. From the simulation results, it is obtained that for overall traffic load up to 72 Mbps, Peering model is the best alternative IP interconnect model. The usage of G.729 codec was the best performance codec with the minimum delay value and the biggest MOS, thus it was the most recommended for used in the IP interconnection implementation.

Abstract

Penelitian ini bertujuan memperkenalkan teknologi yang sedang dikembangkan untuk dapat mengirimkan paket data tanpa langsung terhubung dengan jaringan backbone, teknologi tersebut dinamakan Delay Tolerant Network (DTN). DTN merupakan jaringan nirkabel dengan kondisi node yang berkomunikasi tidak dapat ditentukan waktunya atau hubungan antara node jarang terjadi. Tidak seperti jaringan konvensional Mobile Ad Hoc Network (MANET), jalur end-to-end antara sumber dengan tujuan hanya akan tersedia dalam waktu yang singkat dan tidak dapat diprediksi. Node pada DTN dapat menjadi source node, intermediate node, maupun node tujuan node, terdiri dari mobile node dan static node yang terhubung dengan delay tinggi. Pada penelitian ini akan dibahas mengenai kinerja VDTN yang menggunakan protokol routing Spray and Focus dan Spray and Wait. Perancangan sistem simulasi terbagi menjadi dua cluster yaitu cluster dengan kecepatan 90 km/jam dan cluster dengan kecepatan 65 km/jam. Kinerja algoritma routing ini disimulasikan menggunakan ONE Simulator. Performansi dievaluasi dengan average latency dan Packet Delivery Ratio (PDR). Observasi yang dilakukan menunjukkan hasil bahwa Spray and Focus memiliki performa yang lebih baik dalam PDR dibandingkan Spray and Wait, tetapi Spray and Focus memiliki performa average latency yang lebih besar dibandingkan Spray and Wait*****DTN is wirelees network where nodes communicate cannot be determined Time or it can be said that the relationship between nodes rare. Unlike conventional network Mobile Ad hoc network (MANET), the end-to-end between the source with destination node will only is ready in a short Time and are not predictable. The node on the DTN can be a source node, intermediate nodes or destination node, consisting of Mobile node and static nodes connected with high delay. In this research will be discussed about VDTN performance using Spray and focus and Spray and wait routing protocol. The design of the simulation system is divided into two Cluster, Cluster’s speed 90 km/h and Cluster’s Speed 65 km/h. Based on observation, the resulting Spray and focus routing algorithm improve performance packet delivery ratio (PDR) than Spray and wait routing algorithm, but Spray and wait have better Avarage Latency than Spray and focus routing algorithm.

Abstract

Information on product prices is one of the things that is often disturbed by society because information about product prices is frequently different among sellers. Whereas the government has made information disclosure in the form of a standard price of a product that aims to reduce price differences among sellers but it cannot be denied that there are several factors that make the price of products different. For example regional factors, transportation, or limited stock. When the community has obtained price information from the government, the public can compare prices on the market. However, the disclosure of information from the government regarding the standard up-to-market price of products on the market is still through internet. Internet media cannot be fully accessed by all people, especially rural communities who still have remote areas such as Gadungan village in Kediri regency. This research was conducted as an alternative technology to facilitate information disclosure of product prices. The method used in this study is action reseach. In this research phase, researchers used the gateway service technology service with a functional PostgreSQL database. The results on usability testing showed that the average score was 88.3%. Application testing results obtained from the application effectiveness level in the range of 89%, the application effectiveness level in the range of 90% and on application satisfaction in the range of 86%. The use of the application is expected to help the public in getting more varied pricing information so as to achieve perfect price competition*****Informasi harga produk menjadi salah satu hal yang sering diresahkan masyarakat karena informasi mengenai harga produk sering berbeda dikalangan penjual. Padahal pemerintah telah melakukan keterbukaan informasi berupa standar harga pokok sebuah produk. Sesungguhnya standar harga produk dari pemerintah tersebut bertujuan untuk mengurangi perbedaan harga di kalangan penjual. Walaupun tidak bisa dipungkiri terdapat beberapa faktor yang membuat harga produk berbeda-beda. Misalnya faktor wilayah, transportasi, ataupun keterbatasan stok. Ketika masyarakat telah memperoleh informasi harga dari pemerintah, masyarakat dapat melakukan perbandingan harga di pasaran. Namun keterbukaan informasi dari pemerintah terkait standar harga produk di pasaran yang up to date masih melalui media internet. Media internet tidak dapat sepenuhnya diakses oleh semua masyarakat, khususnya masyarakat desa yang masih memiliki kawasan wilayah terpencil seperti Desa Gadungan Kab. Kediri. Penelitian ini dilakukan sebagai alternatif teknologi untuk menfasilitasi keterbukaan informasi harga produk. Metode yang digunakan dalam penelitian ini adalah action research. Penelitian ini menggunakan layanan teknologi gateway service dengan fungsional database PostgreSQL. Hasil penelitian berdasarkan pengujian usability testing diketahui bahwa rata-rata score adalah 88,3%. Hasil pengujian aplikasi didapatkan dari tingkat efektivitas aplikasi pada kisaran 89%, tingkat efektivitas aplikasi pada kisaran 90% dan pada kepuasan aplikasi pada kisaran 86%. Penggunaan aplikasi diharapkan dapat membantu masyarakat dalam mendapatkan informasi harga lebih variatif sehingga mencapai persaingan harga sempurna dengan teknologi informasi menggunakan metode gateway service.

Abstract

Abstract The performance of communications is determined by the channel, therefore knowledge of channel model of a country is important. This paper proposes (i) the fifth telecommunication generation (5G) Indonesia channel model and (ii) a framework to derive the channel model of any locations in Indonesia. We consider operating frequency of 3.3 GHz with bandwidth of 40 MHz with real-field parameters of several cities in Indonesia. We also present a theoretical outage performance evaluated for the proposed Indonesia 5G channel model validated by block error rate (BLER) performances of cyclic-prefix orthogonal frequency division multiplexing (CP-OFDM) numerology zero with 5G complex binary phase shift keying (C-BPSK) and Polar coding scheme. Sub-optimal Polar codes are used in this research, where better performances are expected in the future. We found that the Indonesia 5G channel model has 17 paths for the case of without foliage effect and has less than 15 paths for the case of with foliage effect. The results show that foliage attenuation causes performance degradations indicated by smaller number of paths and worse theoretical outage performances. The obtained outage performances from the proposed Indonesia 5G channel model in this paper are expected to be a reference for 5G implementations in Indonesia. Abstrak Kinerja sistem komunikasi ditentukan oleh kanal, sehingga pengetahuan model kanal suatu negara menjadi penting. Makalah ini mengusulkan (i) model kanal telekomunikasi generasi ke-lima (5G) Indonesia dan (ii) kerangka kerja untuk menghitung model kanal di lokasi lain di Indonesia. Model kanal dalam makalah ini diciptakan untuk bandwidth 40 MHz pada frekuensi 3,3 GHz dengan parameter riil lapangan. Makalah ini juga menampilkan teori outage performance yang diperoleh dari model kanal 5G Indonesia, kemudian memvalidasi teori outage performance tersebut menggunakan block error rate (BLER) pada cyclic-prefix orthogonal frequency division multiplexing (CP-OFDM) numerology zero dengan complex binary phase shift keying (C-BPSK) standard 5G dan Polar coding. Semua hasil numerik diperoleh dari simulasi komputer menggunakan parameter riil lapangan untuk alam Indonesia. Makalah ini menemukan bahwa kanal 5G Indonesia dapat dimodelkan power delay profile (PDP) dengan 17 path untuk kanal tanpa efek dedaunan dan kurang dari 15 path untuk kanal dengan dedaunan. Hasil tersebut menunjukkan bahwa redaman daun menyebabkan penurunan kinerja, yang ditandai dengan penurunan jumlah path dan memburuknya outage performance. Kurva outage performance yang diperoleh dari model kanal 5G Indonesia diharapkan menjadi referensi untuk implementasi sistem 5G di Indonesia dalam pengembangan 5G di Indonesia secara optimal, terutama untuk lokasi yang memiliki dedaunan lebat.

Abstract

Previous studies have shown that business performance is mostly determined by the ability of a company to create competitive advantage. However, the rapid changes in technology, markets, regulations and hypercompetition have made the business environment increasingly uncertain and unpredictable so that it can erode competitive advantage. This phenomenon is known as the turbulence of business environment and can cause a company to have difficulty maintaining its competitive advantage so that it is very interesting to study further. The purpose of this study is to understand how the turbulence of business environment occurs in the telecommunications industry in Indonesia. The study involved 213 leaders of business units of telecommunications operators in Indonesia as research respondents. The research methods used are descriptive survey and explanatory survey using component-based structural modeling, Partial Least Square-Path Modeling (PLS-PM). The results of the study showed that the telecommunications industry in Indonesia has experienced high turbulence of business environment, caused mainly by competitive turbulence. However, it was found that the technological turbulence and the market turbulence have contributed the most dominant to the occurrence of turbulence business environment in telecommunication industry. This study also discussed the problem solving of the business environment turbulence and recommendations for the sustainability of the telecommunications industry in Indonesia.*****Tujuan dari penelitian ini adalah untuk mendapatkan gambaran bagaimana turbulensi lingkungan bisnis yang terjadi pada industri telekomunikasi di Indonesia. Penelitian melibatkan pimpinan unit bisnis penyelenggara telekomunikasi sebagai responden penelitian. Metode penelitian yang digunakan adalah metode descriptive survey dan explanatory survei menggunakan pemodelan struktural berbasis komponen yaitu Partial Least Square-Path Modelling (PLS-PM). Hasil penelitian menunjukkan bahwa industri penyelenggaraan telekomunikasi di Indonesia mengalami gejolak turbulensi lingkungan bisnis yang tinggi, disebabkan terutama oleh turbulensi lingkungan kompetisi. Meskipun demikian, ditemukan bahwa sesungguhnya turbulensi lingkungan teknologi dan turbulensi lingkungan pasar yang berkontribusi paling dominan terhadap terjadinya turbulensi lingkungan bisnis pada industri telekomunikasi. Dalam penelitian ini juga dibahas pemecahan masalah turbulensi lingkungan bisnis tersebut dan rekomendasinya bagi keberlangsungan industri telekomunikasi di Indonesia.
