"TELKOM mengembangkan layanan Indonesia WiFi (wireless fidelity) segmen carrier untuk menghasilkan pendapatan baru pada bisnis wholesale dengan memberikan layanan sebagai alternatif solusi bagi operator seluler dalam mengantisipasi lonjakan trafik data. Layanan Indonesia WiFi segmen carrier diawali kerjasama antara TELKOM dengan Telkomsel sejak April 2012 dengan layanan Web Service dan mulai Oktober 2012 dilengkapi dengan layanan Offload. Namun bagi TELKOM implementasi layanan ini belum berjalan baik ditandai adanya perbedaan yang cukup tinggi antara target dan realisasi pendapatan dan jumlah penggelaran titik akses pada tahun 2012 dan triwulan I 2013. Penelitian ini mengevaluasi implementasi bisnis Indonesia WiFi segmen carrier sampai dengan triwulan I 2013. Menemukan penyebab tidak tercapainya target pendapatan pada bisnis ini dan memberikan usulan tindakan korektif berdasarkan hasil evaluasi implementasi layanan Wifi segmen carrier. Kemudian melakukan simulasi proyeksi pencapaian pendapatan layanan Indonesia WiFI segmen carrier Telkomsel tahun 2013 berdasarkan usulan tindakan korektif. Hasil evaluasi menemukan penyebab tidak tercapainya pendapatan layanan Indonesia WiFI segmen carrier Telkomsel adalah adanya skema bisnis wholesale untuk layanan Web Service yang berpotensi tidak dapat menghasilkan pendapatan yang tinggi bagi TELKOM walaupun pemakaian layanan tinggi, jumlah penggelaran titik akses belum sesuai rencana, jumlah titik akses yang tidak berfungsi cukup banyak, dan penggunaan layanan WiFi Offload yang masih relatif sedikit baik jumlah pengguna maupun trafiknya. Usulan tindakan korektif untuk perbaikan kondisi berupa perubahan skema bisnis dari pola bagi hasil (revenue sharing) menjadi berdasarkan jumlah pemakaian (volume based), perbaikan kinerja dalam penggelaran titik akses baik pencapaian jumlah penggelaran maupun meningkatkan availability titik akses sesuai kontrak TELKOM dan Telkomsel. Hasil simulasi proyeksi pendapatan layanan WiFi segmen carrier berdasarkan usulan tindakan korektif berpotensi meningkatkan pendapatan layanan WiFi segmen carrier sebesar 158 kali lebih tinggi (dari 991 juta rupiah menjadi 157 miliar rupiah) untuk jumlah titik akses 250K dibandingkan tanpa melakukan tindakan korektif.

TELKOM develop Indonesia WiFi (wireless fidelity) carrier segment to generate new revenue in the wholesale business by providing services as an alternative solution for mobile operators in anticipation of a surge in data traffic. Indonesia WiFi carrier segment initiated cooperation between TELKOM and Telkomsel since April 2012 with a Web Service service began in October 2012 with Offload services. But for TELKOM implementation of these services has not gone well, characterized by a high difference between the target with the realization of revenue and the number of access point deployment in 2012 and the first quarter of 2013.

This study evaluated the business implementation of the Indonesian WiFi carrier segment until the first quarter of 2013. Finding the cause of not achieving the revenue targets on this business and proposes corrective actions based on the results of evaluation of Wi-Fi service carrier segment implementation. Then Simulate the estimated revenue performance in 2013 based on the proposed corrective actions.

Evaluation results have found the cause not achieving revenue targets of Indonesia WiFI carrier segment are a wholesale business scheme for Web Service service which can not generate high revenue for TELKOM despite high use of services, the number of access point deployment has not been as planned, many access points are disorder, and WiFi Offload services is still a few number of users and the traffic either.

Proposed corrective actions to improve conditions are changes in the wholesale business scheme from revenue sharing to be based on the amount of usage (volume based), improved performance of access point in the achievement of number of deployment and increase availability according to the contract of TELKOM and Telkomsel.

Simulation results of estimation of WiFi service carrier segment revenue based on the proposed corrective action could potentially increase revenue WiFi service carrier segment is 158 times (from 991 milion rupiahs to 157 billion rupiahs) higher than without corrective action for the number of access points 250K."

"ABSTRAKIndustri telekomunikasi saat ini sedang mengalami penurunan. Laba usaha tertekan oleh penurunan pendapatan sedangkan sejumlah komponen biaya mengalami peningkatan. Berbagai cara dapat dilakukan untuk menekan beban biaya modal dan operasional. Misalnya saja dengan mengimplementasikan wireless network virtualization untuk memaksimalkan pemanfaatan infrastruktur yang telah ada. Skenario yang digunakan dalam penelitian ini menyajikan sebuah pemodelan sistem yang menggambarkan interaksi antar operator-operator telekomunikasi seluler yang menerapkan distributed dynamic spectrum sharing dalam sebuah jaringan radio kognitif dengan menggunakan data-data faktual berupa parameter-parameter teknis yang diterapkan pada jaringan LTE milik PT. XYZ di wilayah Bali, Indonesia. Dari hasil perhitungan berdasarkan pemodelan sistem yang telah dibuat, diketahui bahwa parameter arrival rate yaitu waktu kedatangan frame packet data dan probabilitas menduduki spektrum frekuensi merupakan dua faktor yang berpengaruh terhadap pencapain throughput masing-masing user. Maximum throughput per user yang mungkin tercapai oleh primary user adalah sebesar 20 Mbps ketika arrival rate primary user 0,27 dan probability primary user sebesar 0,6 atau 0,5. Sedangkan maximum troughput secondary user 1 dan 2 yang mungkin tercapai adalah 16,56 Mbps dan 15,75 Mbps pada saat arrival rate masing-masing user tersebut sebesar 0,22 dan 0,21 dan probabilitas menduduki spektrum frekuensi bagi masing-masing secondary user sebesar 0,35. Parameter-parameter ini sangat erat kaitannya dengan parameter-parameter QoS Quality of Service pada jaringan mobile data, yaitu latency delay dan jitter serta parameter capacity design yaitu admission control yang menentukan maximum connected user per cell pada jaringan LTE.

ABSTRACTTelecommunication industry is currently experiencing a declined in growth. The companies rsquo net profit is pressed down by the decreasing in total income, while cost components have increased. Various ways can be done to lower the capital and operational costs. For example, by implementing wireless network virtualization to maximize the utilization of existing infrastructure. In this research, scenario analysis of the implementation of wireless network virtualization using techno economic analysis. The scenario used in this research presents a modeling system that describes the interaction between mobile telecommunication operators applying distributed dynamic spectrum sharing in a cognitive radio network using factual data in the form of technical parameters applied to the LTE network owned by PT. XYZ in Bali, Indonesia. From the calculation results based on system model, it is known that the arrival rate parameter , that is the arrival time of the frame packet data and the probability of occupying the spectrum frequency are two factors that influence the achievement of each user throughput. Maximum throughput per user that may be reached by the primary user is 20 Mbps when the arrival rate of primary user is 0,27 and the probability of primary user is 0,6 or 0,5. While the maximum troughput of secondary users 1 and 2 that may be achieved is 16,56 Mbps and 15,75 Mbps at the arrival rate of each user is 0,22 and 0,21 and the probability of occupying the spectrum frequency for each secondary user is 0.35. These parameters are closely related to QoS Quality of Service parameters in mobile data networks, i.e. latency delay and jitter, and the capacity design parameters are admission control which determines maximum connected user per cell on LTE network."

"Kehadiran sistem komunikasi wireless generasi kelima (5G) akan mampu mendukung berbagai skenario dan aplikasi penggunaan yang lebih beragam dibandingkan teknologi sebelumnya (4G). Salah satu skenario penggunaan yang menjadi kunci dari ekosistem 5G adalah URLLC (Ultra-Reliable Low Latency Communication). URLLC akan berperan sebagai penyedia konektivitas bagi aplikasi dan layanan baru seperti industry automation, autonomous vehicle, dan lain sebagainya. Namun, mengimplementasikan 5G URLLC merupakan tantangan yang cukup besar bagi operator. Jaringan operator harus dapat memenuhi persyaratan ketat URLLC, terutama kebutuhan akan nilai latensi yang sangat rendah (hingga 1 ms). Oleh karena itu, penting bagi setiap operator untuk mengetahui terlebih dahulu kondisi serta kemampuan jaringan eksisting yang mereka miliki saat ini dalam memenuhi persyaratan tersebut. Dalam penelitian ini, penulis menggunakan studi kasus dari salah satu operator di Indonesia untuk mendapatkan data pengukuran performansi jaringan, mengevaluasinya, dan kemudian mengembangkan langkah-langkah strategis dalam mengatasi permasalahan latensi untuk mendukung 5G URLLC. Pengukuran performansi dilakukan dengan menggunakan metode TWAMP (Two-Way Active Measurement Protocol) terhadap jaringan 4G eksisting. Performansi jaringan diukur antara dua titik dari core ke site 4G eksisting operator dimana keduanya akan merepresentasikan koneksi antara data center dengan site pada jaringan 5G. Dari hasil pengukuran, diperoleh korelasi yang sangat kuat antara latensi dengan jarak dari site ke core (data center) dengan nilai koefisien korelasi Pearson 0.76. Hal ini menandakan adanya pengaruh yang kuat antara jarak data center ke site terhadap besarnya nilai latensi jaringan. Hasil analisis lebih lanjut menemukan bahwa bahwa jarak maksimum antara site ke data center untuk mencapai latensi 1 ms adalah 21,4 km menggunakan infrastruktur jaringan eksisting. Berdasarkan hasil tersebut, penulis juga mengembangkan desain optimal untuk lokasi penempatan data center serta skema.......The presence of a fifth generations wireless communication system (5G) will be able to support a variety of scenarios and use-cases that are more diverse than the previous technology (4G). One of the key use-cases for the 5G ecosystem is URLLC (Ultra- Reliable Low Latency Communication). URLLC will play a significant role in providing connectivity for new applications and services such as industrial automation, autonomous vehicles, and so on. However, implementing 5G URLLC is quite a challenge for operators. Operator’s networks must be able to meet the stringent requirements of URLLC, especially the need for very low latency values (up to 1 ms). Therefore, it is important for each operator to know in advance the conditions and capabilities of their existing network to fulfill these requirements. In this study, the authors used a case study from one of the operators in Indonesia to obtain network performance measurement data, evaluate it, and then develop strategic steps in overcoming latency problems to support 5G URLLC. Performance measurement is carried out using the TWAMP (Two-Way Active Measurement Protocol) method on the existing 4G network. Network performance is measured between two points from the core to the operator's existing 4G sites which both of it will represent the connection between the data center and the sites on the 5G network. From the measurement results, we obtained a very strong correlation between latency and the distance from the site to the core (data center) with a Pearson correlation coefficient of 0.76. This indicates a strong influence of the distance from the data center to the sites on the network latency value. The results of further analysis found that the maximum distance between the sites to the data center is 21.4 km in order to achieve 1 ms of latency using the existing network infrastructure. Based on these results, the authors also developed optimal designs for data center placement locations as well as efficient schemes for operators to build new 5G infrastructure."

"Komunikasi nirkabel menjadi kebutuhan mendasar seiring dengan perkembangan teknologi komunikasi karena menawarkan biaya yang lebih rendah, fleksibilitas dan kenyamanan yang lebih tinggi, peningkatan kecepatan dan konektivitas yang konstan, serta aksesibilitas ke daerah yang jauh. Salah satu contoh teknologi komunikasi yang berkembang pesar saat ini adalah teknologi VSAT (Very Small Aperture Terminal). VSAT adalah stasiun bumi satelit dua arah yang beroperasi pada frekuensi C-band dan Ku-band, dengan dua macam polarisasi (linear dan melingkar) di C-band dan polarisasi linear di Ku-band. Agar data yang dipancarkan satelit dapat dimanfaatkan oleh pengguna sistem komunikasi, maka dibutuhkan antena pada sisi pengguna yang memiliki karakteristik dual wideband dengan dual-polarization. Penelitian ini merancang antena planar dual wideband dual-polarization dengan metode pemasangan dua port. Dalam proses perancangan antena dualband, pemberian slot pada patch mampu menghasilkan karakteristik dualband. Selain untuk memberikan karakteristik polarisasi melingkar, metode pertubasi juga dapat dilakukan untuk menambahkan karakteristik wideband pada antena. Agar antena dapat menghasilkan karakteristik polarisasi melingkar, dapat dilakukan dengan memberikan slot pada ground antena. Rancangan antena yang diusulkan memiliki frekuensi resonan yaitu 3,75 – 4,68 GHz dan 5,6 – 9,3 GHz pada port 1 serta 3,13 – 5,72 GHz dan 10,41 – 12,29 GHz pada port 2. Antena memiliki karakteristik polarisasi melingkar (RHCP) pada port 1 dan polarisasi linear pada port 2. Pada port 1, gain di frekuensi 4,2 GHz dan 6,2 GHz masing-masing terukur pada nilai 3,4 dB dan 4,5 dB, sedangkan pada port 2, gain di frekuensi 3,9 GHz, 6,13 GHz dan 11,8 GHz masing-masing terukur pada nilai 2,12 dB, 2,52 dB dan 6,13 dB. Antena mampu beresonansi di sebagian frekuensi C-band (port 1), baik pemancar dan penerima, serta sebagian frekuensi penerima Ku-band (port 2). Antena yang diusulkan memiliki dimensi yang kecil (30 mm x 39 mm x 1,52 mm), serta desain yang lebih compact dan sederhana sehingga memudahkan proses fabrikasi.

Wireless communication has become a fundamental requirement along with the development of communication technology because it offers lower costs, higher flexibility and convenience, constant increases in speed and connectivity, as well as accessibility to remote areas. One example of a communication technology that is currently developing rapidly is VSAT (Very Small Aperture Terminal) technology. VSAT is a two-way satellite earth station operating on the C-band and Ku-band frequencies, with two kinds of polarization (linear and circular) in the C-band and linear polarization in the Ku-band. In order for the data transmitted by the satellite to be utilized by users of the communication system, an antenna on the user side that has dual wideband characteristics with dual-polarization is needed. This study designed a dual-polarization planar antenna with a two-port installation method. In the process of designing a dualband antenna, providing a slot on the patch can produce dualband characteristics. In addition to providing circular polarization characteristics, the pertubation method can also be used to add wideband characteristics to the antenna. So that the antenna can produce circular polarization characteristics, it can be done by providing a slot in the antenna ground. The proposed antenna design has resonant frequencies, namely 3.75 - 4.68 GHz and 5.6 - 9.3 GHz on port 1 and 3.13 - 5.72 GHz and 10.41 - 12.29 GHz on port 2. The antenna has a circular polarization characteristic (RHCP) on port 1 and linear polarization on port 2. At port 1, the gain at a frequency of 4.2 GHz and 6.2 GHz is measured at a value of 3.4 dB and 4.5 dB, respectively, while at port 1 port 2, the gain at a frequency of 3.9 GHz, 6.13 GHz and 11.8 GHz, respectively measured at a value of 2.12 dB, 2.52 dB and 6.13 dB. The antenna is capable of resonating on part of the C-band (port 1) frequencies, both transmitter and receiver, as well as part of Ku-band (port 2) receiver frequencies. The proposed antenna has small dimensions (30 mm x 39 mm x 1.52 mm), as well as a more compact and simple design that facilitates the fabrication process."

"Perangkat implan medis memainkan peran penting sebagai perangkat medis karena manfaatnya dalam memantau dan mendeteksi gejalan penyakit. Pada perangkat implant medis yang bekerja secara nirkabel, dibutuhkan Wireless power dan data transfer (WPDT) sebagai alat komunikasi berdaya rendah antara implan dengan penerima di luar tubuh pasien. Namun, topologi rangkaian WPDT yang sederhana masih menjadi tantangan karena rangkaian WPDT yang sudah dikembangkan sebelumnya masih menggunakan rangkaian yang kompleks dengan dua tautan daya induktif untuk pengiriman daya dan data secara terpisah. Pada penelitian ini diusulkan rangkaian WPDT yang dapat mengirim daya dan data pada satu tautan daya induktif yang sama dengan menggunakan teknik modulasi amplitude-shift keying (ASK) sebagai metode pengiriman data. Pada rangkaian yang diajukan, tingkat efisiensi yang didapat sebesar 40,2% dengan daya terkirim ke beban sebesar 51,5 mW. Pada frekuensi pengiriman data 1 MHz; 1,5 MHz; dan 2 MHz bit error rate (BER) yang terukur kurang dari 10-8.......Medical implant devices play an important role as medical devices due to their benefits in monitoring and detecting disease conditions. In wireless medical implant devices, Wireless power and data Transfer (WPDT) is required as a low-power communication tool between the implant and an external receiver outside the patient's body. However, the simplicity of WPDT circuit topology remains a challenge as previously developed WPDT circuits still use complex circuits with two separate inductive power links for power and data transmission. This research proposes a WPT circuit that can transmit power and data over the same inductive power link using the Amplitude-Shift Keying (ASK) modulation technique as the data transmission method. In the proposed circuit, the achieved efficiency level is 40.2% with a power delivered to the load of 51.5 mW. At data transmission frequencies of 1 MHz, 1.5 MHz, and 2 MHz, the measured Bit Error Rate (BER) is less than 10-8"

"Pada 31 December 2019, virus Corona diidentifikasi di kota Wuhan, Cina. Pada 2 Maret 2020, virus Corona telah ditemukan keberadaanya di Indonesia. Gejala umum yang disebabkan oleh corona diantara lain ialah demam, batuk kering, serta kelelahan. Dengan gejala serius dalam bentuk kesulitan bernafas, hilangnya kemampuan untuk berbicara dan bergerak, serta kematian. Corona dapat menyebar dari pengidap ke orang lain yang berdekatan melalui kontak fisik maupun melalui cairan pengidap virus Corona. Tenaga medis merupakan kelompok yang memiliki risiko tinggi untuk mengidap penyakit yang disebabkan oleh virus Corona. Di mana untuk tiap 100 orang yang menjangkit corona, 6 sampai 7 diantaranya merupakan tenaga medis. Dengan risiko tinggi yang dihadapi oleh tenaga medis, timbul kebutuhan akan interaksi serta pembacaan tanda vital pasien dari jarak jauh. Salah satu metode untuk berinteraksi dengan pasien dari jarak jauh ialah dengan menggunakan teleoperated robot arm. Teleoperated robot arm dapat membaca berbagai tanda vital pasien yaitu tekanan darah, temperatur tubuh, saturasi oksigen darah, serta detak jantung. Teleoperated robot arm dapat dikendalikan oleh pengguna di ruangan yang terpisah dari pasien menggunakan protokol komunikasi MQTT. Penelitian ini bertujuan untuk merancang teleoperated robot arm yang dapat dikendalikan dari jarak jauh untuk meminimalisir kontak langsung antara pasien dan tenaga medis untuk mengurangi risiko tenaga medis mengidap virus Corona.......At the 31st of December 2021, the Corona virus has been identified in Wuhan, China. At 2nd of March 2021, the Corona virus’s existence has been identified in Indonesia. The light symptoms that are caused by the Corona virus are fever, dry cough, and fatigue. The serious symptoms are difficulty breathing, loss of ability to speak and or move, and death. The Corona virus can spread from person to person through physical contact or liquid from the virus’s carrier. Medical Personnels are amongst the highest group to be in risk of contracting the Corona virus. For every 100 people that contracted the Corona virus, 6-7 of them are medical personnel. The high risk that medical personnel face in regards to contracting Corona virus caused the urgency for indirect interaction between patients and medical personnel to rise. One of the methods that could achieve indirect interaction between patients and medical personell is through a teleoperated robot arm. The teleoperated robot arm could read various vital signs from the patient such as the heart beat, the oxygen saturation level, the blood pressure, and the body temperature. The Teleoperated robot arm can be controlled wirelessly by the user that is located in a different room from the patient using the MQTT communication protocol. The goal of this research is to design a teleoperated robot arm that is able to be controlled remotely by a user to minimize the direct contact between a patient and a medical personell to reduce the risk of contracting the Corona virus"

"In recent times, the demand for the real time audio and video applications in wireless networks is very high due to widespread use of latest wireless communication technologies. Many of these applications require different Quality of Service (QoS) in terms of delay and throughput in the resource constrained wireless networks. In order to handle the resources effectively and to increase the QoS, proper packet scheduling algorithms need to be developed. Low-latency Queuing (LLQ) is a packet scheduling algorithm which combines Strict Priority Queuing (SPQ) to Class-Based Weighted Fair Queuing (CB-WFQ). LLQ places delay sensitive applications such as voice and video in the SPQ and treat them preferentially over other traffic by allowing the application to be processed and sent first from the SPQ. In this paper, an Enhanced LLQ (ELLQ) is proposed. An additional SPQ is introduced for scheduling the video applications separately along with the dedicated SPQ for voice applications. The performance of the proposed algorithm is compared with other existing algorithms through simulations using the OPNET modeler. Simulation and Statistical results show that the proposed algorithm has given 1.5 times performance improvement in terms of throughput and delay than the existing algorithms for the real time audio and video applications."
