Abstract

Perencanaan jaringan telekomunikasi merupakan hal yang sangat menentukan dalam kualitas sinyal pada jaringan yang diterima oleh pelanggam. Permasalahan yang sering terjadi adalah kualitas level sinyal coverage yang tidak merata terutama pada kondisi dalam gedung (Indoor). Sehingga kondisi dalam bangunan memerlukan perancanaan khusus untuk memastikan kondisi kualitas sinyal agar tidak terdapat blank spot. Pada penelitian ini merencanaan jaringan indoor 4G LTE frekuensi 1800 MHz dengan menggunakan model propagasi COST-231 pada gedung Laboratorium Fakultas Kedokteran Universitas Muhammadiyah Palembang. Penelitian ini menggunakan software radiowave propagation simulator. Hasil dari penelitian ini yaitu dengan perbedaan power transmit (2 antenna vertikal) menunjukkan bahwa semakin tinggi nilai power transmit, maka nilai RSRP semakin baik. Akan tetapi nilai power transmit tidak mempengaruhi baik atau buruknya kualitas sinyal SIR.Pada analisa jumlah antenna yaitu 2 antenna, 3 anntena dan 4 antenna menunjukkan bahwa semakin banyak antenna yang digunakan pada gedung, maka nilai RSRP akan semakin baik, akan tetapi nilai SIR akan semakin jelek karena efek Interferensi antar antenna.

Abstract

Water is one of the most widely used natural products by humans, such as for daily needs for drinking, cooking, bathing, washing and others, even industry, agriculture, offices all need water. Water is a basic human need, but it is still found in some areas with limited and difficult to reach water sources. This study aims to analyze the performance of photovoltaic (solar panels) and the results of the electric pump in the implementation of a solar power generation system (PLTS). In this study, designing a solar power plant (PLTS) that is connected to a solar charge controller and connected directly to a water pump system using a battery as a source. Based on the results of the study, it shows that the higher the solar radiation, the higher the output power of the 200 Wp PV module. Likewise, changes in reservoir height greatly affect changes in water discharge and currents. The higher the reservoir well distance, the smaller the water discharge and the higher the reservoir well distance also affects the increase in current.

Abstract

Propagation modeling is the most important part of mobile wireless network planning. Wireless network planning requires an accurate calculation of the path, which depends on different environmental conditions. It requires accurate path loss modeling of the characteristics of a specific region. The study aimed to obtain a path loss propagation model by modifying the ECC model and using linear, logarithmic regression in lowland areas. The measurement used drive test method, located in the Jakabaring area that represented the lowland area. This research used four existing path loss models, namely Okumura-Hatta, COST-Hatta, Ericsson Model, and ECC Model. It was found that the Okumura-Hatta model had the largest RMSE value, 34.90, followed by the Ericsson model, 27.07, while the ECC model had the smallest RMSE value, 8.43. The ECC model required to be modified using logarithmic, linear regression to obtain the proposed model. The results of the evaluation showed that the proposed model improved with RMSE 4.93, MAPE 2.71, and MAD 3.91, whereas the values of the existing ECC Model before modification were 8.43 for RMSE, 4.72 for MAPE and 7.09 for MAD. The proposed model provided an accurate prediction of the path loss propagation in a lowland environment. The results of the study can be used for planning engineers to plan, design, and implement the wireless communication networks in lowland area conditions.

Abstract

Penggunaan daya listrik di rumah tangga selama ini hanya dapat dilihat melalui alat ukur kWh meter yang didistribusikan oleh PLN. Penggunaan alat tersebut tidak memberikan informasi tentang berapa besar daya listrik yang digunakan secara real-time. kWh meter hanya menunjukkan jumlah daya kumulatif yang terpakai. Oleh karena itu, diperlukan alat yang dapat memperlihatkan penggunaan daya listrik secara real-time, sehingga memudahkan penggunauntuk memantau konsumsi energi listrik. Tujuan penelitian adalah memonitoring beban listrik rumah tangga menggunakan arduino NodeMCU ESP8266 secara real-time. Metode yang digunakan dalam penelitian ini terdiri dari 4 tahapan, yaitu : 1). Pemilihan peralatan software dan hardware, 2). Perancangan sistem, 3). Pembuatan program, dan 4). Pengujian alat. Hasil dari pengujian alat menggunakan beban induktif berupa lampu LED 15 Watt sebanyak 2 buah dan beban resistif berupa setrika listrik yang diset pada titik panas maksimum, alat bekerja dengan baik dan mampu membaca besaran arus dan daya yang digunakan pada saat pengkondisian ON terhadap beban induktif dan beban resistif, tingkat akurasi alat dalam membaca berkisar 96% sampai dengan 98%.

Abstract

Propagasi radio memilki peranan yang sangat penting dalam perkembangan jaringan telekomunikasi. Sinyal yang ditransmisikan oleh pengirim ke penerima mengalami redaman yang mengurangi kuat sinyal pada sisi penerima. Redaman yang terjadi pada saat perambatan gelombang di sebabkan oleh Large Scale Fading yang disebabkan oleh pengaruh benda dan bangunan yang ada disekitarnya. Penelitian ini bertujuan untuk membandingkan karakteristik path loss propagasi terhadap beberapa parameter yang ada pada sisi pengiriman maupun penerima serta membandingkan model propagasi large scale yang digunakan saat ini dalam jaringan LTE (Long Term Evolution). Simulasi dilakukan dengan dengan menggunakan Model propagasi Okumura-Hata dan Cost-231 Hata serta menganalisa pengaruh path loss berdasarkan perubahan frekuensi, ketinggian BTS dan juga perbedaan karakteristik wilayah yaitu urban, sub-urban dan rural. Hasil dari penelitian menunjukkan bahwa pada pemodelan Okumura-Hata dan Cost-Hata mempunyai profil path loss yang hampir saya yaitu penggunaan frekuensi yang semakin tinggi, path loss yang dihasilkan semakin besar. Begitu juga dengan ketinggian antenna pemancar, semakin tinggi antenna pengirim maka path loss yang dihasilkan semakin kecil. Dari sisi karakteritik wilayah meunjukkan bahwa path loss yang dihasilkan pada daerah urban lebih tinggi dibandingkan dengan daerah sub-urban maupun rural area dikarenakan wilayah urban memiliki struktur bangunan yang lebih tinggi dan padat.

Abstract

The telecommunication has a tremendous improvement in terms of data rates and bandwidth requiring sufficient frequency allocation and wideband spectrum availability. The millimeter-wave frequency band is one of the solution to these requirements, however communications in this band is facing new challenges on the climate effect to the channel propagation  In this paper, we propose a 5G channel model considering the effect of humidity based on the characteristic of the natural environment of Palembang city. The channel model is represented by power levels and delay called a Power Delay Profile (PDP and is derived based on a series of computer simulations using parameters of nature in Palembang. The 5G channel model is important to further derive the outage performance to be used as the theoretical performance of 5G in Palembang since the the Shannon Channel Capacity Theorem is involved in the derivation. We conduct a series of computer simulations to evaluate the validity of the proposed channel model and its characteristics. We found that humidity affect to the performances, where high humidity makes the performances of outage and BER slightly worse, although the effect may be ignored for some applications. The results of this paper are expected to be the references for the development and implementation of 5G Networks especially at the mm-Wave band in Palembang.
