Abstract

Salah satu sistem komunikasi yang merupakan andalan bagi terselenggaranya integrasi sistem telekomunikasi secara global adalah sistem komunikasi nir-kabel. Teknologi nirkabel banyak digunakan oleh masyarakat karena harganya yang sangat terjangkau. Tingginya kebutuhan internet pada perkembangan zaman pada saat ini untuk menunjang efektifitas dan efisiensi pengguna terutama pada saat ini dunia khususnya Indonesia sedang  dilanda musibah corona virus19 (covid19) yang mengharuskan semua menghentikan aktifitas normal, sehingga aktifitas bekerja sekolah maupun perkuliahan mahasiswa yang biasanya dilakukan tatap muka diganti secara daring (dalam jaringan) yang dilakukan dari rumah masing-masing. Akan tetapi perkembangan informasi tersebut tidak dapat dirasakan bagi masyarakat khususnya yang tinggal di area sinyal yang tidak stabil, sehingga sangat mengganggu aktifitas belajar mengajar mahasiswa yang di lakukan secara daring karena sulitnya mengakses jaringan internet di area yang tidak stabil tersebut khususnya di Desa Siak Kampung Jawa tengah. Tujuan penelitian ini untuk merancang dan mengiplementasikan antena kaleng di desa siak kampung jawa tengah supaya berguna bagi masyarakat disana sebagai penunjang akses belajar mengajar di masa pandemi ini. Hasil dari pengukuran antena Kaleng dilakukan pada lokasi yang telah ditetapkan, lokasi yang telah ditetapkan berjarak 5 hingga 7 km dari lokasi BTS Telkomsel, XL dan Smartfren dengan asumsi di lokasi tersebut masih bisa menerima sinyal 4G namun level dayanya sangat rendah dan tidak dapat menerima sinyal internet dengan baik jika menggunakan antena Kaleng dapat menerima sinyal internet yang cukup.

Abstract

The need for a communication system with a higher data rate and mobility grows along with information and communication technology development. Combining MC-CDMA with the MIMO system and supporting the system with a good transmit diversity technique is a promising idea to provide the needed communication system, especially in high mobility conditions. MC-CDMA can support ubiquitous communications without affecting the achievable BER and is more capable of high-speed mobility. It integrates the benefit of both OFDM and CDMA. On the other hand, QO-STBC increases the bit rate without using additional bandwidth to transmit diversity in the MIMO system. So, this study proposed a system combining the MIMO MC-CDMA system with QO-STBC. The proposed system is investigated under high mobility conditions to see the system's performance. The simulation results show that our system performs better than the MC-CDMA STBC system and the QOSTBC system but not better than the MC-CDMA multilevel coding scheme. To reach the value of BER 10−3, MC-CDMA multilevel Coding requires less power, around 5 dB, than the proposed system.

Abstract

Information is now a basic need for every people, including the people in border areas. Therefore, it is an obligation for the government to provide information media that can be reached by all levels of society, one of which is FM radio broadcast media. This research aims to identify and assess the quality of FM radio broadcasts in the border area of Sambas Regency using several antenna models which in the area is a vulnerable area of signal leakage by neighbouring countries and far from Indonesian broadcast transmitters. The assessment of FM radio broadcast quality is carried out with the determination of SINPO (Signal, Interference, Noise, Propagation, Overall) values and field strength meter measurements. The data obtained were analysed using the Miles and Hubberman interactive data processing technique. From the research conducted, it was found that 10 Malaysian FM radio broadcast channels and 2 broadcast channels from Indonesia where the dominant broadcast was received better by the yagi antenna. There were also broadcasts whose frequencies fell out of compliance with the regulations.

Abstract

This research employs Optisystem for evaluating network quality through calculation and simulation. It includes direct observation of installed devices at Perum 4 East Pontianak and network simulations using parameters like Power Link Budget, Rise Time Budget, BER, and Q factor. Calculations indicate that power levels on the downstream and upstream sides meet the standard. RTB analysis and BER and Q factor simulations confirm compliance with PT Panglima Kamayo Media and ITU-T G.984 standards. However, a design-implementation mismatch affects two consumers with significant power deviations, necessitating network improvements. PLB and RTB calculations on both sides confirm compliance with standards, and simulations validate the furthest network's feasibility. Yet, two specific consumers, 24 and 27, require improvements due to Prx power exceeding limits. These enhancements should consider internal and external factors, such as anthill interference. Overall, Perum 4 East Pontianak's FTTH network meets standards with potential improvements for uniformity, offering valuable guidance for PT Panglima Kamayo Media in enhancing consumer services.

Abstract

The reliable spread of BTS networks with high system capacity poses a challenge for operators in delivering services. An alternative strategy is network sharing, one of which is MOCN (Multi Operator Core Network). MOCN BTS is configured to share RF module and antenna resources by combining frequencies between operators while maintaining each operator's core. On the other hand, BTS not-pair is the conventional operator configuration where RF modules and antennas are installed independently without any connection to other operators. In this final project, a KPI data analysis is conducted for both BTS configuration to assess their reliability. Four BTS samples from two operators (IM3 and 3ID) are taken for this analysis. The analyzed KPI categories include Accessibility KPI, Retainability KPI, and Service Integrity KPI during busy hours. KPI data is obtained from field results and assisted by the technical team from Indosat Ooredoo Hutchison Pontianak. The analysis results indicate that in terms of Service Integrity KPI, BTS MOCN outperforms BTS not-pair, with a difference of 2.590175 Mbps for downlink and 0.286065 Mbps for uplink. Regarding Accessibility KPI and Retainability KPI, BTS managed by 3ID demonstrates better performance compared to those managed by IM3.

Abstract

Matlab is a software that is capable of performing calculations and simulations as well as developing Graphical User Interface (GUI) based application. The development of GUI based application can be used to perform complex calculations, one of which is the calculation of microstrip antenna dimensions. Microstrip antenna is a type of antenna that consists of a thin conductor laid over a dielectric substrate. The purpose of this research and development is to describe the programming language process so as to produce an effective GUI to determine the dimensions of the microstrip antenna to be designed. By providing input values in the form of dielectric constant, dielectric height, frequency, and impedance, the GUI will process this input into output values in the form of patch dimensions, feedline dimensions, and ground plane dimensions. This GUI will be made stand-alone so the users do not need to open the Matlab application to use it. The GUI will present buttons that are easy for users to use where each button has been adjusted to its respective function. The calculation of microstrip antenna dimensions from the GUI will be tested by comparing the output value with output value from the previous journals. In addition, to test the usefulness of each button, the blackbox testing where the result obtained were that all buttons could work according to their respective functions without any problems or errors so that the GUI can be used for determining the dimensions of microstrip antennas. Then, to test the appearance of the GUI, survey of potential users was conducted to determine the level of user satisfaction with resulting GUI.
