Abstract

Tujuan penelitian ini untuk mendapatkan gambaran mengenai keunggulan bersaing penyelenggara telekomunikasi dan mengeksplorasi bagaimana menciptakankeunggulan bersaing yang superior dalam lingkungan bisnis yang bergejolak.Penelitian melibatkan pimpinan unit bisnis penyelenggara telekomunikasi di Indonesia sebagai responden penelitian dengan metode descriptive survey dan explanatory survey menggunakan Partial Least Square-Path Modelling (PLS-PM). Dari analisis deskriptif, diperoleh bahwa keunggulan bersaing penyelenggara telekomunikasi di Indonesia termasuk dalam kategori baik dan lebih banyak dibangun melalui efisiensi produk, terutama efisiensi yang lebih tinggi dalam menghasilkan produk atau layanan.Namun demikian, hasil penelitian menunjukkan bahwa kecepatan respon pasar memiliki kontribusi yang lebih dominan dalam menciptakan keunggulan bersaing yang superior pada lingkungan bisnis yang bergejolak. Untuk mengatasi masalah ini, penyelenggara telekomunikasi di Indonesia perlu meningkatkan kemampuannya,terutama dalam menciptakan respon yang lebih cepat untuk memasuki pasar-pasar baru serta menghasilkan produk atau layanan dengan biaya yang lebih rendah. This study aims to describe the competitive advantage of the telecommunications provider and explore how to create a superior competitive advantage in the turbulent business environment. The study involved many leaders of business units of telecommunications operators in Indonesia as research respondents. The research uses descriptive survey and explanatory survey using Partial Least Square-Path Modeling (PLS-PM). From the descriptive analysis, it is found that the competitive advantage of telecommunications operators in Indonesia belongs to the excellent category, and was built more through product cost-efficiency, especially higher efficiency in producing products or services. However, the results of the study show that market responsiveness turned out to have a more dominant contribution in creating a superior competitive advantage in a turbulent business environment. Thus, the competitive advantage is still not optimal. To solve this problem, the telecommunications provider in Indonesia needs to increase the ability to quickly enter new markets and produce products or services at a lower cost.

Abstract

AbstrakPenelitian ini bertujuan membandingkan besarnya biaya penyelenggaraan teknologi LTE pada pita frekuensi 900 MHz, 1800 MHz, 2100 MHz, dan 2300 MHz. Selain itu, dilakukan cost benefit analysis untuk melihat kelayakan bisnis teknologi LTE pada frekuensi tersebut. Penelitian ini menggunakan pendekatan kuantitatif dengan melakukan perhitungan link budget dan capacity dimensioning untuk memperoleh jumlah infrastruktur yang dibutuhkan, serta melakukan perhitungan biaya dan pendapatan untuk dilakukan cost benefit analysis (CBA). Hasil penelitian menunjukkan bahwa pembiayaan operasional terbesar pada pembangunan jaringan LTE adalah BHP, kemudian disusul dengan harga sewa site. Biaya terbesar ada pada penggunaan pita frekuensi 2100 MHz dikarenakan BHP pita tersebut paling tinggi dibanding dengan frekuensi lainnya. Dari keempat frekuensi tersebut, frekuensi 2300 MHz paling layak digunakan, karena nilai BHP yang paling rendah dibanding frekuensi yang lain.  Berdasarkan hasil perhitungan, pembangunan jaringan LTE pada keempat frekuensi tersebut layak dilakukan, dengan internal rate of return (IRR) terbesar pada pita frekuensi 2300 MHz. AbstractThis study aims to compare the cost of developing LTE technology at 900 MHz, 1800 MHz, 2100 MHz, and 2300 MHz frequencies. In addition, cost-benefit analysis is carried out to find the feasibility of LTE technology business at those frequencies. This study uses a quantitative approach by conducting link budget and capacity dimensioning to obtain the number of cellular infrastructures. This study identifies and calculates cost and revenue for conducting cost-benefit analysis (CBA). The result shows that the most significant operational cost of LTE network development is BHP frequency (frequency license fee,) followed by site leasing cost. The most significant cost of LTE planning development from those frequencies is at 2100 MHz, because the frequency license fee of that frequency is the most expensive one among the other frequencies. The frequency of 2300 MHz is the most feasible frequency to use, since the frequency 2300 MHz license fee is the cheapest one among the other frequencies. According to the calculation result, LTE development at those frequencies is feasible, with the largest internal rate of return (IRR) is in the frequency of 2300 MHz.

Abstract

Di Indonesia, tidak semua daerah telah terintegrasi oleh jaringan 4G LTE dengan baik, sehingga memerlukan perencanaan 4G LTE yang tepat. Penelitian ini melakukan perancangan penambahan eNodeB baru dengan metode fronthaul microwave 4G LTE, dengan tujuan untuk memperbaiki bad coverage pada suatu area melalui peningkatan coverage dan kapasitas jaringan. Link fronthaul menggunakan frekuensi 71 GHz, penempatannya dengan menggunakan metode drive test untuk mencari bad coverage di Purwokerto Utara, Purwokerto Barat, dan Purwokerto Selatan. Hasil dari penentuan daerah bad coverage kemudian dibuat site hop berdasarkan site existing terdekat dengan daerah bad coverage tersebut. Dari hasil simulasi menggunakan Atoll 3.3.0, rata-rata kenaikan RSRP setelah ditambahkan fronthaul RSRP-nya, -91,7 dBm, naik 20%, dan CINR sebesar 13,95 dB, kenaikan sebesar 12%. Sedangkan untuk throughput, mengalami kenaikan setelah ditambahkan fronthaul, rata-rata menjadi 90,75 Mbps, dari 52,12 Mbps, naik 72%. Untuk simulasi link fronthaul microwave 71 GHz, level daya terima saat tidak terjadi hujan, sebesar rata-rata RSL -27,52 dBm, dan pada saat hujan, RSL turun, -58,17 dBm, dari ambang batas minimum -48 dBm. Untuk keandalan sistem, mendapat annual multipath availability pada 6 hop sebesar 99,999%, akan tetapi pada annual rain, availability rata-rata sebesar 99,90%. In Indonesia, not all regions have been integrated by the 4G LTE network, so it needs the optimal 4G LTE Planning. In this study, we plan the new eNodeB  with fronthaul microwave 4G LTE method to solve the bad coverage problem in certain area by increasing coverage and capacity network with this method. The fronthaul links uses 71 GHz frequency and the placement of this link uses the drive test method to look for bad coverage in the North Purwokerto, West Purwokerto, and South Purwokerto. The results of the bad coverage were then used as a hopping site based on the site closest to the area's bad coverage. From the simulation results using Atoll 3.3.0, the average RSRP increases after fronthaul RSRP added, -91.7 dBm, up 20%, and CINR by 13.95 dB, rose by 12%. While for throughput, increased after adding fronthaul, on average to 90.75 Mbps, from 52.12 Mbps, up 72%. For the 71 GHz fronthaul microwave  link simulation, the level of receiving power when there is no rain, RSL -27.52 dBm on average, and when it rains, RSL drops, -58.17 dBm, from the minimum threshold of -48 dBm. For system feasibility, the availability of annual multipath at six hops is 99.999%, but on average annual rainfall, availability is 99.90%.

Abstract

VoIP is a digital communication technology that is currently developing because VoIP can be implemented on several network topologies, such as bus, star, and ring. Each of these topologies has advantages and disadvantages. So, a study is required to find out in which topology can VoIP be implemented optimally. In this research, VoIP is implemented in several topologies and furthermore the performance measurements are carried out for each topology. VQ manager is installed in order to measure the VoIP performance. For the server, we used Elastix and for the node implementation network topologies, we use several access points. From the results of the research, the performance of VoIP implemented in the star topology produces QoS that is better than other topologies with a delay value of 185 ms, 18 ms jitter, and 1% packet loss. This happens because in the star topology, all packets are distributed centrally. It is expected that the results of this research can be used as a reference in the application of VoIP technology in several types of topologies.

Abstract

Operasi satelit di Indonesia yang dikenal luas adalah tentang operasi satelit-satelit di orbit geostasioner (GSO) untuk misi telekomunikasi. Namun, dalam dekade terakhir ini, operasi satelit-satelit non-GSO di Indonesia meningkat dengan pesat. Sehingga, tujuan dari penelitian ini adalah mengetahui mengapa peningkatan tersebut terjadi dan mendapatkan gambaran tentang masa depan operasi satelit non-GSO di Indonesia. Untuk tujuan tersebut, dilakukan ulasan atas operasi satelit non-GSO yang lalu dan saat ini. Analisis dilakukan pada karakteristik misi, pemilik/operator, dan spesifikasi dari satelit-satelit tersebut. Selain itu, dilakukan kajian pustaka tentang tren global dan lingkungan strategis yang menentukannya. Hasil studi menyimpulkan bahwa penyebab pertumbuhan satelit non-GSO di Indonesia adalah bertambahnya penggunaan aplikasi penginderaan jauh, aplikasi M2M, dan pengembangan satelit oleh LAPAN. Di masa depan, diperkirakan naiknya penggunaan satelit non-GSO untuk penginderaan jauh akan disebabkan oleh faktor yang sama. Namun, untuk telekomunikasi, akan lebih didorong oleh beroperasinya konstelasi satelit global baru. Peningkatan penggunaan satelit non-GSO untuk penginderaan jauh tidak berakibat banyak pada kebutuhan frekuensi dan stasiun Bumi. Sementara, kenaikan penggunaan satelit non-GSO untuk telekomunikasi akan memerlukan tambahan alokasi frekuensi dan stasiun Bumi yang cukup banyak.    Indonesian satellite operations are mainly known for the operation of geostationary orbit (GSO) satellites for telecommunication missions. In the last decade, however, the activities of non-GSO satellites in Indonesia are significantly increasing. Therefore, the objectives of this research are to find out the cause of the growth and to predict the future operation of non-GSO satellites in Indonesia. For such purpose, review on the operation of non-GSO satellites in the past and now was done. Analysis on the characteristics of their missions, owners/operators, and technical characteristics of the satellites were done. Literature studies on the global trends and their defining strategic environments were also done to complete the insight. The study shows that increase in the use of non-GSO satellites is caused by the growth in remote sensing application, M2M application, and development of LAPAN’s satellites. In the future, the growth of non-GSO remote sensing satellite is predicted to be caused by the same reason. The increase in the use of non-GSO telecommunication satellites, however, will be affected more by the new global trend. The increase in non-GSO remote sensing satellites does not affect significantly on the needs of frequency and ground stations. The increase in the non-GSO telecommunication satellites, however, needs significant additional frequency allocations and ground stations.

Abstract

Abstrak Teknologi telekomunikasi yang banyak dimanfaatkan untuk berkomunikasi di era internet saat ini adalah teknologi Long Term Evolution (LTE). Dalam menyelenggarakan layanan LTE, diperlukan suatu penghubung antara jaringan akses dengan core yang biasa dikenal dengan istilah backhaul. Salah satu backhaul yang biasa digunakan untuk menyambungkan suatu link komunikasi ini adalah backhaul microwave. Penerapan dari link microwave ini biasa digunakan untuk komunikasi line of sight (LOS). Oleh karena itu, perencanaan link microwave ini tidak mudah karena akan ada banyak faktor yang mempengaruhi link komunikasi ini, diantaranya: penghalang, fading, atenuasi, noise maupun jarak. Pada penelitian ini akan dilakukan perencanaan link microwave antara Kota Semarang dengan Kota Magelang dengan 3 skenario. Skenario pertama dilakukan dengan komunikasi langsung singlehop, skenario kedua dengan memanfaatkan repeater aktif, dan skenario ketiga dilakukan dengan repeater pasif. Hasil akhir menunjukan bahwa skenario yang paling sesuai untuk diimplementasi pada link microwave Semarang-Magelang ini adalah skenario kedua. Penggunaan repeater aktif yang memantulkan dan menguatkan sinyal site Tx menuju site Rx ini mampu menjadi solusi untuk lintasan link yang terdapat obstacle dan berjarak sangat jauh. Penggunaan skenario 2 dalam penelitian ini menunjukan kekuatan signal di site Semarang dan Magelang adalah masing-masing -54,67 dBm dan -48,66 dBm. Kekuatan sinyal ini berada di atas Rx threshold pada kedua site, yaitu -67,50 dBm. Abstract Telecommunication technology that is widely used to communicate in the internet era today is Long Term Evolution (LTE) technology. In carrying out LTE services, the link is needed between the access network and the core or commonly known as backhaul. One of the backhaul widely used to connect a communication link is a microwave backhaul. The application of a microwave link uses extensively for the line of sight (LOS) communication. Therefore, this microwave link planning is not easy because there will be many factors that influenced the communication link, include barriers, fading, attenuation, noise, and distance. In this research, microwave link planning will be carried out between the Semarang City and the Magelang City using three scenarios. The first scenario conducted by using single-hop or direct communication, the second scenario using an active repeater, then the third scenario using the passive repeater. The last result shows that the most suitable scene to be applied in the Semarang-Magelang microwave link is the second scenario. Using active repeater, which reflecting and amplifying the Tx site signal towards the Rx site, is considered to be a solution for the link trajectory, which contained high obstacle and great distance. Using the second scenario from this research, showing that the signal power at Semarang and Magelang site is -54,67 dBm and -48,66 dBm. These signals are above both of Rx threshold site, that is -67,50 dBm.

Abstract

Abstrak Perkembangan jangkauan dan penggunaan internet mendorong pengembangan penyediaan layanan dengan transmisi data yang cepat dan kapasitas yang besar seperti layanan berbasis serat optik. Jaringan long-haul DWDM sebagai teknologi multipleksing sangat mendukung proses transmisi optik jarak jauh. Performa media transmisi long-haul DWDM membutuhkan teknik pengkodean kanal yang dapat diimplementasikan pada sisi pengirim agar diperoleh sistem yang efisien dalam hal bandwidth transmisi. Dalam komunikasi serat optik terdapat beberapa jenis teknik pengkodean kanal yang umum digunakan seperti non-return-to-zero (NRZ) dan return-to-zero (RZ). Penelitian ini bertujuan untuk membandingkan kinerja rancangan sistem dengan variasi teknik pengkodean dengan memberikan variasi daya pancar laser sebesar 0, 2, 4, 6, dan 8 dBm dan variasi jarak sebesar 200, 400, 600, 800, dan 1000 km. Rancangan sistem menggunakan modulasi eksternal dan NRZ atau RZ pada sisi transmitter, serat optik dan penguat EDFA pada media transmisi, dan detektor optik pada sisi receiver. Berdasarkan hasil penelitian, tidak semua kanal sesuai dengan hasil Q-factor dan BER berdasarkan standar ITU-T, namun jenis pengkodean kanal NRZ lebih baik digunakan pada jenis jaringan long-haul DWDM. Abstract The increasing of coverage area and demand for internet services are both drive the development of providing services with high bitrate transmission and gigantic capacity, such as fiber optic communication. Long-haul DWDM network as a multiplexing technology is very supportive in the long-distance optical transmission link requiring channel coding which can be implemented in transmitter. There are various types of channel coding used in optical fiber communication, such as non-return-to-zero and return-to-zero. The aims of this work are to compare the system performance with different channel coding in long-haul link using variations of optical power launch with value 0, 2, 4, 6, and 8 dBm and variations of length of link with value 200, 400, 600, 800, and 1000 km. The design system uses external modulation and NRZ or RZ on the transmitter, optical Fiber with EDFA amplifier on the optical transmission, and optical detector on the receiver. Based on the results, there are several channels with the Q-factor and BER that do not meet the ITU standards. In addition, the NRZ channel coding is better used in the long-haul DWDM link.

Abstract

Underwater acoustic communication is a technology that uses sound or acoustic waves and water as its propagation medium. This technology has been used in various fields, such as underwater wireless sensor networks, underwater monitoring system, and surveillance systems. An acoustic modem is required to facilitate communication between nodes. In this paper, an underwater acoustic modem using Frequency Shift Keying (FSK) modulation has been designed. This modulation is widely used because of its reliability and simple design. FSK modem was designed using M=2 level or known as Binary FSK (BFSK) with 40 kHz mark frequency and 43 kHz space frequency. This study tested data packets sending and its error rate against the distance variation. Testing for 70-bit data resulted in 1% error at 100 cm distance and 37% error at 170 cm distance. When compared with the previous testing at 1200 bps which resulted in 0% and 35% error, it can be seen that error at 1200 bps is better than at 2400 bps, but the data transmission was better at 2400 bps. Addition to the number of bits sent and distance has an influence on the error value, i.e. the greater the distance and the amount of data sent, the greater the error value.

Abstract

The antenna performance is seen from the S-parameter value. The S-parameter graph can be seen as the return loss (S11, S22) and the mutual coupling (S21, S12) value. This research focuses on analyzing mutual coupling on Square and Vivaldi array antennas using the ring metamaterial method. The value of mutual coupling is considered very important to analyze because it affects the performance of the antenna in which is arranged in an array. The simulation results of the mutual coupling value obtained on a square array antenna use a ring metamaterial is -17 dB at a frequency of 2.4 GHz. Meanwhile, the Vivaldi array antenna uses a ring metamaterial that produces a mutual coupling value of -13.840744 dB at a frequency of 3.0162 GHz. The factors that affect the square array antenna so that it becomes the best to suppress the mutual coupling value between antenna elements are a selection of metamaterial shape and proper placement between the antenna array elements is arranged horizontally.
