Abstract

The use of composite materials is currently growing, composites have the advantages of low density, corrosion resistance, environmental friendliness and a simple manufacturing process. Composite is a material composed of two main ingredients, namely the matrix (binding material) and filler (filler material). In this study, the filler used was rice straw while the matrix was epoxy resin and polyester resin. The object of this research is to make and carry out a series of tests on straw fiber composite materials with variations in fiber length of 15 mm and 25 mm made by the hand lay up method. The test was carried out to determine the strength of the material and also to recalculate the weight fraction of the actual rice straw fiber resin composite to be compared with the initial volume fraction of 20% straw. The results on composite materials using polyester resin are stronger than epoxy, judging from the average price of polyester with a fiber length of 15 mm, namely the bending strength of 32.04 MPa. Calculation of weight fraction of rice straw fiber resin composite by hand lay up process with epoxy resin is 38.75 gr, while polyester resin is 24.59 gr

Abstract

Perkembangan teknologi pada saat ini sangatlah pesat, hal ini terbukti dengan banyaknya penemuan-penemuan yang setiap hari ditemukan oleh para peneliti. Salah satu bidang yang memiliki perkembangan teknologi yang pesat yaitu kedirgantaraan. Kedirgantaraan mencakup suatu benda yang memiliki kemampuan terbang dengan memanfaatkan engine atau prinsip aerodinamika. Sumber energi utama pada UAV ini terdapat pada baterai. Baterai merupakan bagian dari sistem UAV yang bertugas menyimpan dan mendistribusikan listrik selama UAV digunakan. Dalam penggunaan UAV, sering kali UAV tiba-tiba jatuh karena kehabisan baterai. Faktor ini terjadi karena kurangnya fitur untuk mengetahui kondisi baterai. Dalam penelitian ini dirancang suatu alat yang dimana rancangan ini akan membantu pengguna untuk memantau kondisi baterai pada pesawat UAV. Rancangan terdiri dari sensor INA60 untuk mengukur tegangan dan arus, mikrokontroler Arduino Nano untuk mengolah data tegangan dan arus menjadi daya dan kapasitas, 3DR radio telemetri kit 433 mhz untuk mengirimkan data dan OLED 0,96 display sebagai media penampil. Berdasarkan hasil pengujian, Rancangan mampu menunjukan parameter tegangan dengan keakuratan total sebesar 99,3%, keakuratan arus sebesar 99,54%, keakuratan daya sebesar 95,78% dan keakuratan persentase sebesar 95,75%. Rancangan mampu mengukur baterai hingga jarak sejauh 36 meter. Diharapkan penelitian selanjutnya menggunakan variasi sensor lainnya guna untuk mendapatkan akurasi yang lebih tinggi

Abstract

In drone design, the selection of components such as batteries, Electronic Speed ​​Controllers and propellers must be in accordance with the requirements, but not all components in the RC include measurement data to determine the specifications of the brushless motor. Therefore, a test tool is needed that can calculate the amount of thrust or use a tool trials. Brushless motors and propellers are important components that affect flying performance on drones. The greater the thrust generated by the brushless motor and propeller, the greater the load that can be lifted by the drone. The types of propellers commonly used in drones include 6x4, 9x6, and 10x5 propellers. To measure the amount of thrust, load sensors and current sensors can be used which are converted by the ADC HX711 converter. The test bench tool can be used to produce data experimentally using the help of the sensor. In testing the 6x4e propeller produced a current of 7.8 Ampere and a thrust of 1.13 kgf, the 9x6e propeller produced a current of 16.4 Ampere and a thrust of 1.63 kgf, and the propeller 10x5e produced a current of 18.6 Amperes and a thrust of 2.07 kgf with the right selection of brushless motors and propellers, drone performance can increase.

Abstract

The purpose of this study was to obtain the QoS value of the data sent from the user terminal to the gateway based on variations in antenna gain and to determine the effect of the level of interference caused by noise on the user's device on the quality of data reception. This research uses the NS3 software experimental method. Parameters analyzed include throughput, delay, PDR. This study uses quasi-experimental methods. The purpose of quasi-experimental research is pure experimental conditions in conditions where it is impossible to control or manipulate all relevant variables, namely estimating. The conclusion in this study has been successfully carried out simulating sending data packets using the NS3 simulator tools. Based on the simulations that have been carried out, several characteristics of the effect of antenna gain on the quality of data packet transmission are obtained. The simulations explain well that the values of throughput, delay, and PDR have increased so as to provide good service quality. Based on the simulations that have been carried out, several characteristics of the influence of the interference level that affect the user on the quality of sending data packets are obtained. The simulation explains well that the values of throughput, delay, and PDR experience stability so that the level of interference has no effect on users in sending packets. However, the values obtained are very good and have not decreased

Abstract

The increasing demand for safe and efficient batteries for renewable energy storage calls for the development of reliable and innovative Battery Management Systems (BMS). One of the main challenges in designing a BMS is creating a system that is not only effective but also easy to build using widely available components. This research aims to produce a BMS circuit design that can contribute to the development of BMS technology in society, with a focus on overcharge and overdischarge protection functions. In the proposed design, the discharge control switch will interrupt the power flow from the battery to the load when any battery cell experiences overdischarge. Similarly, the charge control switch will disconnect the charging power from the charger to the battery when a cell experiences overcharge, and the charging will resume if all battery cells are within safe conditions. This design aims to safety in battery usage across various applications, while providing an easily implementable BMS solution that can be widely adopted by society.
