Abstract

Dalam tugas akhir ini dibahas tentang merancang jaringan indoor 4G LTE di gedung Student Centre Universitas Budi Luhur Jakarta mengunakan femtocell. Dengan memperhitungkan nilai total loss yang disebabkan oleh material-material didalam gedung, dengan bantuan model propagasi COST 231 Multi-Wall maka akan didapatkan prediksi cakupan yang efektif untuk tiap FAP (Femtocell Access Point). Setelah diperoleh prediksi cakupan efektif tiap FAP-nya maka akan diperoleh jumlah FAP yang diperlukan untuk men-cover seluruh area didalam gedung dan kemudian akan disimulasikan dengan software Radiowave Propagation Simulator (RPS) untuk memprediksi hasil rancangan yang telah dibuat dari sisi perhitungan secara coverage. Hasil yang diharapkan dari perencanaan Jaringan indoor 4G LTE di gedung Student Center Universitas Budi Luhur Jakarta adalah agar nilai Reference Signal Received Power (RSRP) dan Signal to Interference Ratio (SIR) jaringan LTE di dalam gedung Student Centre berada dalam range yang baik sesuai dengan standar Key Performance Indicator (KPI) 3GPP, yaitu >-80dBm (RSRP) dan > 5dB (SIR). Serta dapat membandingkan hasil simulasi dari 3 skenario yang telah dibuat dengan nilai mean RSRP dan SIR dari setiap skenario, sehingga didapatkan skenario penempatan femtocell yang paling baik.

Abstract

The problem that often occurs in cubicles today is the corona, a phenomenon that occurs when the air around the conductor or conductor is ionized. This is what accelerates the occurrence of the corona. The design of the temperature and humidity control system is made using the Wemos D1 Mini microcontroller, the DHT11 sensor as a temperature and humidity reader sensor, this tool also uses a relay as an automatic switch to turn on and off the fan and also a dehumidifier and installed NodeMCU Esp8266 to send results to smartphones. The way the temperature and humidity control system works using the DHT11 sensor, the sensor senses the temperature and humidity objects in the cubicle, then the data obtained will be processed by the Wemos D1 Mini microcontroller in serial communication. Then the received data will be processed according to the set point, where the temperature is set at 35ºC and the humidity is set at 50% RH. So that if the temperature and humidity are more than the set point value, the relay will work to activate the dehumidifier and fan until the temperature and humidity reach the specified values then it will turn off again. And the data that has been read will be displayed on the LCD / smartphone and stored in the database. From the results of taking temperature and humidity data at substations SP13, KJ274 and KJ365, the results were obtained to test the prototype tool. It takes 8 minutes for the humidity to reach 79% of the initial value of 30% and 13 minutes for the temperature to reach 49ºC from the initial temperature of 26ºC. In the test, the prototype tool can control temperature and humidity to the bottom of the set point and keep it below the set point, so that the occurrence of coronas caused by high humidity can be minimized.

Abstract

Have been created a quad-ridge horn (QRH) antennas the working frequency at 8GHz - 12 GHz. This type of antenna is commonly used in the RADAR (Radio Detection And Ranging) and Detection Systems. The design results will be simulated using WIPL-D software to find out whether the design results are appropriate or not with the desired conditions. The next stage is the manufacture of antennas and the entire implementation of the fabrication carried out in the lathe service workshop to obtain precise size results. Because the size of the antenna is small (10cm - 20cm), with a thickness of ±10mm stainless-steel material, so it is not possible to do it alone. The quad-ridged horn antenna performance will be observed in testing using a vector network analyzer (VNA) measuring device whose working frequency ranges from 100KHz - 8.5GHz. The measurement results obtained, QRH antenna works at 8.33 GHz frequency. With the difference in antenna working frequency practically it will affect other variables such as return loss, VSWR, gain and antenna radiation diagram. This is due to differences in the dimensions of the antenna which has a shift in the value of several centimeters (cm) when in the fabrication process.

Abstract

The mosque is a place of worship for Muslims. The Ministry of Religion issued provisions regarding different designations for mosques. One of the prayer rooms in Kelurahan Kreo Selatan is the Al-Hasanah Mosque which is located at Gang Sawo No. 27, RT.01/RW.13, Kelurahan Kreo Selatan, Kecqmqtqn Larangan, Kota Tangerang, Banten. Al-Hasanah Mosque congregation is growing rapidly and DKM intends to expand the mosque building and turn it into a mosque. The current condition of the Al-Hasanah prayer room consists of a 1-story building. And the early history of this prayer room was a house belonging to the congregation which was then donated to become a prayer room. The current condition of the Al-Hasanah Mosque needs to be developed because the congregation of the Al-Hasanah Mosque is increasing and is becoming increasingly unaccommodated. Based on these conditions, Budi Luhur University Architecture Study Program organized Community Service activities to jointly prepare the Al-Hasanah Mosque Renovation Budget Plan. The method of implementing the activities uses the Architectural Design Process. Where the renovation design of the Al-Hasanah Mosque is adjusted to the input from the mosque manager, while the working drawings of the mosque renovation design are adjusted to architectural standards. Then proceed with the calculation of costs (RAB) based on the preliminary drawings that have been mutually agreed upon

Abstract

Budi Luhur University in collaboration with residents of Pondok Lakah Permai Ciledug housing, collaborates in the field of household scale waste management to be used as biogas raw material. The problem faced by environmental managers is that waste is not transported then rot. To solve this problem, the waste is processed into biogas through a fermentation process. The fermentation process is used to break down organic waste into methane gas which can be used for cooking. The role of the community is needed to collect waste raw materials and sort organic and non-organic waste. The purpose of this community service activity is to empower residents to separate waste from household waste to be processed into biogas. The method used is to provide counseling and continue with the manufacture of a waste chopping blender to process the waste. The results of this service can be concluded that the first one has produced a biogas reactor unit and a waste crusher / blender, then after training to the target community on how to make a biogas reactor, the second conclusion is that the two communities can operate the tools that have been made and can also sort waste. as a raw material for biogas. In this activity, the community understands how to protect the environment and can operate a waste chopping biodigester and blender so that the waste that had been piling up is now processed into biogas.

Abstract

Lemahnya sinyal wireless yang digunakan sebagai link transmisi gelombang radio akan menyebabkan kinerja yang kurang baik pada perangkat pendukung komunikasi jaringan internet. Kondisi ini sering terjadi pada daerah daerah tertentu dimana lokasinya berada jauh dari jangkauan sinyal yag dipancarkan oleh BTS. Jika hasil pengukuran kekuatan sinyal transmisi wireless berada diantara -100dBm s/d -9,0dBm maka sinyal transmisi dikategorikan pada kondisi yang lemah, sehingga kemungkinan terjadinya error dalam transmisi data menjadi tinggi. Sedangkan sinyal yang memiliki kekuatan diatas -80dBm dapat dikategorikan sebagai sinyal transmisi yang kuat. Maka untuk meningkatkan kualitas sinyal transmisi wireless dapat diwujudkan dengan melakukan rancang bangun perangkat berupa prototipe Antena-Grid yang mampu memfokuskan kekuatan sinyal transmisi pada suatu titik fokus sehingga sinyal yang dikumpulkan pada titik fokus antena mengalami pengingkatan gain, sehingga kapasitas data yang dapat disalurkan mengalami peningkatan , baik pada arah uplink maupun arah downlink. Pengukuran dilakukan dengan 2 Aplikasi berbasis wireless , yaitu Network Cell Info dan Open signal , masing masing percobaan dilakukan selama 5 hari untuk mendapatkan data pengukuran kekuatan sinyal yang terbaik , Hasil yang diperoleh adalah adanya peningkatan dalam dalam kekuatan sinyal trasmisi yang diperoleh berada dalam range -80dBm sampai -70dBm, yang merupakan sinyal yang dapat dikategorikan kuat. Selain itu kecepatan transfer data berada dalam range 2,8 Mbps sampai 4,8 Mbps, yang merupakan kecepatan yang cukup baik jika digunakan untuk mentransmisikan data internet.
