Abstract

In a telecommunications system, a radio propagation model is needed to do a design, construction, and development of mobile communication systems. Propagation models commonly used are the Okumura-Hatta model and the COST model 231. These models are used to determine an accurate propagation model in a particular area. This study aims to obtain a propagation model on the environmental conditions of dry-land such as the University of Nusa Cendana areas by using Okumura-Hata path loss modeling and COST-231. In this study, the acceptance test drive was carried out at frequencies of 900 Mhz, 1800 Mhz and 1900 MHz using the G-NetTrack application on Telkomsel BTS in the University of Nusa Cendana area with Latitude coordinates -10.156738 and Longitude 123.668422 as well as observing frequencies using Spectrum Analyzer to be used as primary data. The next step is to calculate the received power data as secondary data using the Okumura-Hata path loss calculation and COST-231. Based on primary and secondary data an analysis of which propagation model matches the measurements in the field is carried out. From the propagation analysis, it can be concluded that the propagation model that suits the conditions on the campus area is the Okumura-Hatta model.

Abstract

The availability of telecommunication infrastructure and services has not been evenly distributed throughout the NTT region. This problem becomes the basis of this research to develop a communication system that capable of reaching areas without a telecommunications network. Through the LORA gateway on the raspberry pi, information from areas that are not covered by telecommunications services is sent to another gateway using a working frequency of 915MHz. The plant in this study is the regulation of soil moisture with the input of 2 sensors and 1 relay for controlling land irrigation activities. An esp8266 sensor node collects the sensing results of the YL-69 and DS18B20 sensors to control the pump motor operation. The process of sending data between the sensor node and the gateway uses the mqtt protocol. Users in areas served by the internet network can access all published data on the test website. The results of controlling the plant area in the test area fluctuated and tended to be stable at between 60% and 80%.

Abstract

Status gizi adalah suatu keadaan yang diakibatkan oleh status keseimbangan antara antara jumlah asupan gizi dan jumlah yang dibutuhkan oleh tubuh untuk berbagai fungsi biologis seperti pertumbuhan fisik, perkembangan, aktivitas, pemeliharan kesehatan, dan lainnya. Agar memudahkan ibu hamil memantau status gizi dan pola konsumsi maka perlu adanya suatu sistem yang dapat memudahkan ibu hamil untuk menggunakan maka sistem dibuat pada smartphone android. Hasil uji program dilakukan selama 20 pengujian untuk status gizi, dimana pengujian tersebut menggunakan metode logika fuzzy, sembilan belas diantaranya sesuai dengan perhitungan rumus Indeks Massa Tubuh dengan nilai validasi = 95%. Hasil uji program dilakukan selama 15 pengujian untuk pola konsumsi, dimana pengujian tersebut menggunakan metode logika fuzzy, 8 diantaranya sesuai dengan perhitungan rumus Angka Kecukupan Gizi Individu dengan nilai validasi = 53%. Sehingga dapat disimpulkan bahwa system dapat digunakan untuk perhitungan status gizi, sedangkan untuk perhitungan pola konsumsi ibu hamil sistem belum layak digunakan.
ANALISIS PENGUKURAN PERFORMANSI JARINGAN 4G LTE PADA AREA LAHAN KERING KEPULAUAN (STUDI KASUS DI WILAYAH AMARASI, KEC. TTS, NTT) Clarita E. Kebos; Beby H.A. Manafe; Kalvein Rantelobo

Abstract

This works takes samples and case studies in the Amarasi area, Kec. TTS, Prov. NTT; because there is still little literature and research conducted in rural areas, especially in the dry land of Semi-arid areas. Therefore, this study analyzes the measurement of the performance of the 4G LTE network, both voice and data communication, carried out in two different conditions, namely outdoor and indoor based on four parameters, namely RSRP, RSRQ, SNR and Throughput. The percentage of the RSRQ category is very good 32%, and bad 1%. The percentage of SNR category is very good 19%, and bad 1%. The average for throughput is 15.81 Mbps download and 18.41 Mbps upload which is good for Kotabes, Tunbaun and Nonbes villages. The measurement results in indoor conditions, the percentage of the RSRP category is very good 4%, and bad 24%. The percentage of SNR category is very good 23%, and bad 1%. The average throughput is 8.79 Mbps download and 11.57 Mbps upload; namely in the villages of Teunbaun, Tunbaun and Aprein. The results of the analysis show that the 4G LTE network has good and promising performance.
