Abstract

ABSTRAKLoRa (Long Range) merupakan suatu sistem komunikasi jarak jauh yang banyak digunakan karena keunggulannya dalam efisiensi penggunaan daya. LoRa dapat memberikan layanan komunikasi dengan jarak yang jauh dengan memanfaatkan modulasi persebaran spektrum LoRa. Teknologi LoRa ini sering digunakankarena implementasinya yang dapat diterapkan dimana-mana, dan dapat diintegrasikan perangkat lain dengan mudah. Modul LoRa yang digunakan adalah produk dari heltec, dengan ESP32 seri ke dua. Dalam modul LoRaini, beberapa komponen telah diintegrasikan menjadi satu, dimulai dari mikrokontroler ESP32 yang diintegrasikan dengan WiFi, LoRa SX1276, dan SSD1306 0.96 inci 128x64 OLED display terhubung via I2C. Pada penelitian ini, didapatkan hasil pengukuran nilai kekuatan sinyal yang diterima (RSSI) maksimal -101 dBpada jarak 400 meter, dimana pada jarak ini data mengalami kehilangan paket dan terjadi delay sekitar 3 detik. Kemudian data-data tersebut berhasil disimpan pada database sehingga dapat dilacak riwayat pengiriman dan penerimaan data.Kata kunci: LoRa, Keamanan Statis, DatabaseABSTRACTLoRa (Long Range) is a long-distance communication system that is widely used because of its superiority inpower usage efficiency.

Abstract

Video on demand (VoD) ialah suatu layanan video streaming yang menggunakan jaringan berkecepatan tinggi dan ditampilkan berupa hasil rekaman video yang telah diperkecil resolusinya serta telah disimpan ke dalam server. Layanan video on demand memiliki standard dalam kualitas pelayanannya, Quality of service (Qos) atau kualitas pelayanan tersebut dapat diukur dengan parameter throughput, delay, packet loss dengan menggunakan network analyzer wireshark. Semakin baik parameter kualitas video on demand tersebut, maka semakin baik video tersebut ditampilkan. proses menampilkan video on demand digunakan dengan teknologi jaringan Fiber to the home (FTTH). FTTH merupakan sebuah jaringan lokal akses fiber yang menggunakan teknologi GPON, dengan jarak askes hingga 20 km dimana menggunakan fiber optik sebagai media utama dalam proses transmisi yang dikirim dari penyedia layanan ke penggunanya. FTTH dapat dikatakan baik ketika memiliki nilai link power budget yang rendah sebagai parameter kualitas jaringan akses. Dan nilai suatu link power budget dapat dikatakan baik ketika nilai redaman jaringan tersebut rendah. Pada penelitian ini dilakukan pengukuran nilai throughput, delay, dan packet loss sebagai parameter kualitas video on demand menggunakan network analyzer wireshark dan parameter redaman untuk mengetahui nilai link power budget pada jaringan FTTH di laboratorium teekomunikasi universitas brawijaya. Dari hasil yang didapatkan nilai dari parameter yang diujikan termasuk kategori yang cukup baik dengan nilai rata-rata 0.488Mbit/s throughput, 24,99 ms delay dan 0,23% packet loss untuk video berkualitas 360p. Kata Kunci: Video on demand (VoD), Fiber to the home (FTTH), Quality of Service (QoS), Link power budget.   ABSTRACT Video on demand (VoD) is a video streaming service that uses high-speed networks and displayed in the form of video recordings that have been reduced in resolution and stored on the server. Video on demand services have standards in the quality services, Quality of service (Qos) or service quality can be measured by the parameters of throughput, delay, packet loss by using a wireshark network analyzer. better quality of video on demand parameters, better the video is displayed. Fiber to the home (FTTH) network technology used for the process of displaying video on demand. FTTH is a local fiber access network that used GPON technology, FTTH has an access up to 20 km because of using fiber optik for transmission process from service provider to users. FTTH will be better when it has a low link power budget value as an access network quality parameter. And the value of a link power budget wil be better when the network attenuation value is low. In this research measurements of the value of throughput, delay, and packet loss as parameters of video on demand quality using wireshark network analyzer and damping parameters to determine the value of link power budget on FTTH networks in the brawijaya university telecommunications laboratory. From the results, the values ​​of the parameters tested are quite good with an average value of 0.488Mbit / s throughput, 24.99 ms delay and 0.23% packet loss for 360p quality videos.

Abstract

Hydroponics is a method of cultivating plants without using soil media. Farming with hydroponic media always pays attention to providing nutrient levels that are in accordance with the needs of plants. The purpose of this research is to test a water and nutrient control system using a PID controller with a setpoint of 500 ppm and 14 cm water level. By using a PID controller, the system produces a small steady state error and gets a faster settling time. The PID controller tuning process using the Ziegler-Nichols 1 method obtained parameter values Kp = 8.4, Ki = 0.15, and Kd = 21. From the test results of nutrient control, it was found that the steady state occurred at the 45th second, overshoot 0% and steady state error was 2.53%. From the results of the water level control test, it is obtained that the steady state occurs at the 175th second, the overshoot is 0% and the steady state error is 0.36%.

Abstract

The potential for solar energy in Indonesia is very profitable if it can be utilized properly and correctly. However, in its application as a power plant, solar panels often encounter problems where the output power generated from solar panels is often less than optimal, so that it will affect the supply of power to the load. The purpose of this study was to determine the effect of theelevation angle of the solar panel on the output power of the 50 WP monocrystalline silicon type solar panel and to determine the installation of solar panels that can produce high output power. The results obtained from this study by adjusting the elevation angle of the solar panel with the HRA (Hour Angle) angle for each hour of solar irradiation can maximize the maximum output power for each hour of irradiation. In addition, another solution for installing solar panels can be done by using the HRA12 angles as an alternative angle for installing solar panels, which in this study obtained an average radiation intensity during solar irradiation hours of 18.22%. Index Terms— Elevation Angle, Output Power, Monocristalline Sillicon, Solar Panel.

Abstract

The increasing demand for vegetables as a consumption commodity and the decreasing availability of land for conventional cultivation have led to hydroponic cultivation as one of the solutions. Unlike soil-based farming, hydroponics uses water as the medium for growing. However, the nutrient levels of hydroponic plants must be maintained within a certain range. Nutrient deficiencies can cause leaves to wilt and curl, while excess nutrients can cause leaves to turn dark green, indicating poor plant health. Thus, the purpose of this research is to develop an automatic nutrient controller that operates according to a setpoint to ensure that hydroponic plants receive the appropriate nutrients. In this study, Mamdani fuzzy logic control is used because of its simple structure, and its linguistic methods can be analyzed mathematically, making it easy to understand. Fuzzy logic control converts crisp input values into fuzzy values using membership functions, then applies the rules that have been created based on implication, followed by rule composition, and finally defuzzification to convert the fuzzy values into crisp output values.
