Abstract

Membanjirnya konten yang diakses oleh civitas akademika di lingkungan kampus menuntut kinerja jaringan yang handal, terutama dalam menangani beban trafik data yang tinggi. Seringkali yang terjadi adalah ketika beban trafik data meningkat, kualitas layanan data yang dapat diberikan akan menurun. Hal ini tentu saja berdampak buruk, terutama layanan komunikasi yang membutuhkan kehandalan tinggi seperti layanan VoIP atau video conference. Untuk mengatasi hal tersebut maka perlu diterapkan suatu metode antrian data yang mampu mengatur distribusi beban lalu lintas data secara efektif dan mampu bekerja dengan baik di segala kondisi beban lalu lintas. Penelitian ini akan mensimulasikan jaringan komputer lokal yang berada di Fakultas Teknik Universitas Tadulako menggunakan tiga jenis metode antrian trafik data yaitu First In First Out (FIFO), Priorityt Queuing (PQ), dan Weighted Fair Queuing (WFQ) dimana tiga protokol akan diuji untuk mengelola tiga jenis layanan yang sering digunakan, antara lain layanan konferensi video, Voice Over Internet Protocol (VoIP), dan Hypertext Transfer Protocol (HTTP) dalam kondisi beban trafik tinggi. Hasil penelitian ini menunjukkan bahwa metode PQ memiliki keunggulan dalam menangani beban trafik data yang tinggi.

Abstract

When designing a wireless sensor network based on ZigBee, it is very important to choose the right network topology, especially in networks with many nodes such as residential areas. Choosing the wrong topology will have an impact on the performance of the wireless sensor network as a whole because it will cause a large delay value. To overcome this, in this study a ZigBee-based wireless sensor network simulation was carried out using an environmental model consisting of several residential units, with one ZigBee device for each house. In addition, three ZigBee network topologies namely mesh, star, and tree are used in this simulation. This is done to determine which topology model will work best in a residential environment. The housing used for the simulation in this study is Citraland Waterfront City Housing which is located in Palu City, Central Sulawesi Province, Indonesia. By using simulations in the Opnet Modeler 14.5 application, it is known that the star topology on the ZigBee network is suitable for application in residential areas with a large number of nodes. This can be seen from the highest throughput values and the lowest media access delay, end-to-end delay, hop number, and packet dropped values compared to tree and mesh topologies.

Abstract

Aquaponics is an agricultural system that combines fish and plant cultivation in one closed system. In an aquaponics system, the water used for fish cultivation is also used to irrigate plants with rice aquaponics as one example. However, monitoring and controlling aquaponic systems is still done manually, which has many shortcomings, including requiring a relatively long time and accuracy that is not guaranteed, especially in large-scale aquaponics management. Implementing the fuzzy algorithm in the rice aquaponics control system aims to make it easier for farmers to monitor the condition of the rice and control the water change system in the pond in real time via the Blynk application on their smartphone. This system combines ESP-32 technology, fuzzy algorithms, and the Internet of Things (IoT) to monitor and control the rice aquaponics system. The results of data collection from the implementation of the fuzzy algorithm in the rice aquaponics control system show that the tool functions well. This tool can monitor the condition of rice and control the water change system in the pond in real time using the Blynk application. The level of accuracy of implementing the fuzzy algorithm for monitoring rice conditions was 99.61% and the accuracy of implementing the fuzzy algorithm for pump control of the water change system was 98.95%.

Abstract

ABSTRAKGrid-tie inverter (GTI) merupakan komponen penting sebagai antar muka antara sistem terintegrasi PLN dan PV. Penelitian ini bertujuan untuk melihat performansi GTI pada sistem beban yang bervariasi. Variasi beban menggunakan beban RLC dalam tiga skenario masing-masing beban 450 Watt, 300 Watt dan 270 Watt. Pengambilan data dilakukan pada rentang waktu satu bulan dengan temperatur dan lama penyinaran rata-rata masing-masing sebesar 27,560C dan 5,14 jam. Hasil pengukuran menunjukkan terjadi perbedaan efisiensi GTI pada setiap nilai beban. Efisiensi maksimum terjadi pada beban 300 Watt. Hal ini mengindikasikan selain pengariuh eksternal pada PV yang mempengaruhi tegangan keluaran, faktor beban juga mempengaruhi efisiensi GTI. Efisiensi GTI yang rendah mengimplikasikan bahwa keterpakaian daya dari catu daya utama masih lebih dominan.Kata kunci: efisiensi, grid tie inverter, variasi beban, PV terintegrasi sistem ABSTRACTGrid-tie inverter (GTI) is an essential component as an interface between PLN and PV integrated systems. This study aims to see the performance of GTI on various load systems. The load variation uses RLC load in three scenarios, each of 450 Watt, 300 Watt, and 270 Watt, divided into five branch points on the PV on-grid module trainer. Data were collected at one month with an average temperature and duration of irradiation of 27.560C and 5.14 hours, respectively. The measurement results show that there is a difference in GTI efficiency at each load value. Maximum efficiency occurs at a 300 Watt load. The value indicates the external influence on the PV that affects the output voltage; the load factor also affects the efficiency of the GTI. The low GTI efficiency implies that the power consumption of the main power supply is still more dominant.Keywords: efficiency, grid tie inverter, load variation, PV-on grid

Abstract

Robotic arms are a type of robot that is currently developing rapidly in industry, this has caused robotics technology to become one of the mandatory subjects taught in universities. In the Undergraduate Department of Electrical Engineering, Faculty of Engineering, Tadulako University, the robotics course is a mandatory subject studied by students, especially students who take the weak current concentration (TEN). This research aims to provide students with an understanding of how to control a robot arm. The design of a robot arm system with 4 degrees of freedom is made using several types of control such as control using Arduino IDE software, push buttons and potentiometers. The results of testing the robot arm trainer after controlling it with three types of control were successful. In the first control using the Arduino IDE software control it shows that the direction of rotation of the motor rotates according to the program target given, in the second control using a push button it shows that the speed and acceleration are directly proportional to changes in motor degrees, then in the third control using a potentiometer it shows that the degree mapping on the potentiometer is directly proportional to the degree of the stepper motor. However, in the test there were differences in degree values ​​when the motor rotated which caused the resulting data to be inaccurate. This is due to a mismatch in tooth size between the belt and the stepper motor gear, causing wear on the belt.
