Abstract

Komunikasi Single-Input Single-Output (SISO) pada dasarnya terdiri atas penggunaan pemancar (Tx) dan penerima (Rx) masing-masing untuk satu buah sistem penyambungan. Cooperative wireless merupakan konsep konektivitas eksis yang terjangkau signal oleh setiap perangkat Tx-Rx lain yang memiliki fungsi sama. Untuk mengandalkan pengoperasian sistem multicarrier maka digunakan Orthogonal Frequency Division Multiplexing (OFDM) agar bandwidth yang tersedia setelah spektrum dibagi menjadi sub band menjadi lebih hemat. Tulisan ini hanya mencakup hasil studi literatur yang bertujuan dalam membangun pemodelan SISO Tx-Rx berbasis OFDM-cooperative yang akan lebih mengoptimalkan fungsi perangkat Tx-Rx sebagai sebuah terminal relay, dimana Tx-Rx akan bekerjasama sebagai relay terhadap sistem lainnya.

Abstract

Fibre Optics is a delivery medium to connect network points to multipoint. FTTH is a service provided to customers to meet internet needs in terms of voice, data and video (triple play) services. PT. Telkom has standards for determining network eligibility, namely Power Link Budget and Rise Time Budget. With a case study in Bontomanai Village, Bulukumba, it is possible to simulate the design of the FTTH network to measure BER (Bit Error Rate) for system performance. From the results of network design calculations that the Power Link Budget, one of which is the attenuation from STO to the customer, is 25.65 dB, where this value is still feasible because it is still in the standard range of PT. Telkom is 13 – 28 dB. The Rise Time Budget parameter obtained based on the analysis is 0.262 ns which has not yet crossed the NRZ degradation limit of 0.28 ns. Simulations have been carried out using Optisystem software to measure BER

Abstract

Cigarette smoke contains toxic chemicals such as carbon monoxide (CO), nicotine and tar. The dangerous/poisonous ingredients in cigarettes cause health problems for those who smoke (active smokers) or those who don't smoke (passive smokers). To avoid the accumulation of cigarette smoke in the room, this research was created and carried out to detect cigarette smoke and reduce the levels of cigarette smoke in the room. Fan. will emit cigarette smoke into the room. The results of the detection of cigarette smoke levels will be sent to Labtop. This system was built using an MQ-2 sensor, ESP8266 microcontroller. The implementation of the cigarette smoke detection system is installed in 3 different rooms/places and is accessed by Internet of Things (IoT) network users. The research results show that every room where this system is installed will send data from cigarette smoke detection results to the lab. The MQ-2 sensor detects cigarette smoke, the data is sent to the internet network via the ESP8266, the data will be displayed on the laptop. From the sample test the tool responded well. This system will activate the fan at certain levels of cigarette smoke to reduce the level of cigarette smoke in the room. When the level is 0 ppm with the Green LED indicator on, the fan is not working or OFF. When the level shows 7 ppm the LED indicator lights up yellow and the fan will turn ON. For the red LED, the cigarette smoke level displayed is 32 ppm with the fan ON. These results prove that the system is functioning properly, detecting and controlling the operation of the fan to remove cigarette smoke from the room and transmit data to the internet network.

Abstract

The development of the tourist area in Celebes Canyon, Libureng Village, Tanete Riaja District, Barru Regency, has enormous potential in utilizing the geological wealth of the area, where the rocks resemble the Grand Canyon in America. Community service activities in Libureng Village aim to provide understanding and socialize the utilization of the geological wealth of Celebes Canyon to the community living around the tourist area, in this case as community service partners, as well as identifying the challenges and opportunities in developing this tourist destination. With an inclusive approach, it is hoped that Celebes Canyon will not only be a tourist attraction, but also provide economic and social benefits to the surrounding community. The method used in this LBE (Laboratory Based Education) community service activity is to conduct observations aimed at obtaining systematic data on the objects to be socialized and continued with socialization activities to the Libureng village community. Based on the results of the observation, it was found that the development of facilities and infrastructure around the tourist attraction needs to be carried out to maintain the geological potential and natural beauty and reduce environmental damage, besides that it is also necessary to always maintain cleanliness around the tourist area. During the socialization activity, a pre-test was conducted on 20 local residents regarding the potential and utilization of geological wealth, as well as the importance of maintaining the environment around the tourist area, the results showed that the level of understanding was in the range of 15% - 42%, but the post-test showed an increase in understanding of 22% - 67%. The importance of cooperation between various stakeholders to create a harmonious partnership in managing tourist attractions; as well as improving the quality of human resources from both managers and local communities is very much needed to support the development of sustainable tourist attractions.
