Abstract

Currently, technological advances are in line with advances in science, so there are many variations that are created for the benefit of human life. Therefore, many problems can be solved by utilizing modern technology, one of which is in agriculture. Watering plants is still mostly done manually and people have difficulty maintaining these plants. Due to the busyness of people's work, it’s difficult to divide the time which makes the plants uncontrollable, so that the plants aren’t well maintained. Utilization of IoT makes daily work easier, especially technology that is practical and efficient. IoT makes devices able to communicate such as sending and receiving data. For this reason, the design and manufacture of an Internet of Things (IoT)-based automatic plant watering control device is carried out. This study designed an automatic watering device consisting of ESP8266, soil moisture sensor and DHT11, where the working system of this tool includes automatic watering of plants based on the water content in the soil, and notifications will be sent to the telegram application. The design of this system will be divided into into three stages, namely, hardware design, software, and use case diagrams. Based on the design results, this automatic plant watering device works successfully by detecting room temperature and reading soil moisture levels. With this tool, it’s hoped that plant owners will get data and values for controlling soil temperature and humidity in accordance with leek plants and become an alternative solution for plant owners in maintaining their plants. The system designed has been able to monitor plant watering, as well as send notifications to users in the form of information about the state of room temperature and soil moisture in plants through the telegram application.Keywords : Internet of Things, Soil Moisture Sensor, DHT11.

Abstract

Intellegent Transportation System (ITS) is a system for solving transportation problems that offers safety, efficiency, and comfort in traffic. Implementation of Vehicular Ad Hoc Network (VANET) that is part of a development of ITS. VANET can be a new innovation in the world of technology that allows to communicate vehicle between vehicle and vehicles with infrastructure. VANET has high node mobility and a routing protocol is required to support VANET communications. In this paper, one of the protocols used are position based routing protocols is Greedy Perimeter Stateless Protocols (GPSR). Density of vehicles in Pekanbaru city make the main problem for implementing VANET communication. VANET communications will result of Packet Delivery Ratio (PDR), end to end delay and routing overhead. In this research, scenario used are 50 node scenario and speed scenario at 10 m/s. The simulation result of VANET with GPSR routing protocol based position shows PDR, end to end delay and data routing value are 99.4860%; 0.0057 seconds dan 6756 packet.Keyword :Intellegent Transportation System, Vehicular ad hoc Network, Greedy Perimeter Stateless Routing

Abstract

Placement of an access point using a Wi-Fi network is necessary to get the desired signal strength, especially from the receiver side. Access Point or transmitter as the signal sender is very important because the signal strength value is a parameter used to determine the coverage area (signal range) of the access point (transmitter). This research discusses the placement of access points in the Faculty of Engineering, University of Riau. In this case, 10 samples of Received Signal Strength Indication (RSSI) in dBm are processed to get the placement optimalization using Simulated Annealing Method with INSSIDER 4 Application. Propagation Line of Sight (LOS) is used to get distance between transmitter and receiver in meters. Signal strength does not only depend on the transmitter and receiver but also from the number of interference the research, it causes the decrease in the signal received by the receiver. Obtained coverage area after optimization 65.233% in the Faculty of Engineering, University of Riau. From the result, hoped this research can be used well to optimize access point placement on Wi-Fi networks using Simulated Annealing Method in the Faculty of Engineering, University of Riau. This system is implemented using Matlab Software.Keywords : Wi-Fi, Coverage Area, RSSI, Propagasi, LOS, Simulated Annealing, Matlab

Abstract

Riau University hospital is an educational infrastructure institution and health institution in collaboration with Riau University. Most of the patients treated at Riau University hospital are people from the riau university community such as campus staff, lecturers and students. Outside communities that are not from the community of UNRI campus have a small percentage to treat in hospitals Riau University. Another problem, for patients who are located far from the hospital of Riau University will have difficulty because patients who want to seek treatment at the University of Riau hospital and conduct consultations with the desired doctor can not know the schedule of the doctor on duty, so the patient must go to the hospital first to find out the schedule of the doctor's duties on the day. Therefore, a consultation application is needed that can help solve the problems described. This research uses waterfall method to help the process of making consulting application. The data collection is obtained by interview method and observation directly to the field. The consulting application was created using Android Studio with the Java programming language and eXtensible Markup Language (XML), as well as Firebase as a database. Application testing uses the User Acceptance Test (UAT) method to see the results of application creation based on user ratings. Based on the results and tests carried out, obtained an android-based UNRI hospital consultation application. This consultation application can be used by patients to view schedules and consult online with doctors working in UNRI hospitals. This application is expected to help prospective patients can seek treatment and consult a doctor easily. Keyword : Java, XML, Android

Abstract

Riau University (UNRI) Library currently uses 802.11ac Wireless Fidelity (Wi-Fi) network. Even though users have used an 802.11ac Wi-Fi network, there are still problems that are often felt by users when accessing the internet such as slow connections, frequent disconnections, and difficulty connecting devices to the Wi-Fi network. Based on these problems, it is necessary to measure the performance of the Wi-Fi network at the UNRI library. Measurements were made during dense traffic using Wireshark and nperf software. The measurement parameters are throughput, packet loss, delay, and jitter. The measurement results show that the throughput and packet loss values of the 802.11AC Wi-Fi network at the UNRI library are still in the good category, with an average value of 1.935 Mbit/s, and packet loss <3 ms. However, the measured delay and jitter values are quite large, with an average delay value of 355 ms and jitter of 848.56 ms.Keywords:Wi-Fi, Throughput, Packet Loss, Delay, Jitter, Access Point, Wireshark

Abstract

LTE is a cellular technology developed by 3GPP which has improved from the previous mobile technologies. The implementation of LTE in Indonesia is still not evenly distributed and only for big cities. Hence, it takes some planning and a deeper study for the area that will be implemented by LTE network. Planning and network optimization is necessary in order to meet consumer needs of the LTE network. There are different ways of optimization methods can be used, in previous studies used a joint base station technique, optimization in other research done by changing basic parameters such as replacing the feeder cable and the addition site. In this study optimization techniques used by changing the type of modulation thus affecting the utilization values of SNR. The simulation results based on two scenarios i.e the number of sites for scenario 1in the total of 479 sites, while for scenario 2 indicates number of sites . in the mean time for a signal level coverage for scenario 1 and scenario 2 show -90 dBm and -95 dBm, respectively.Keywords : LTE, Optimization, Modulation, SINR.
