Abstract

Abstract Banana is a fruit plant that is widely produced in Indonesia. Unfortunately, this plant is verysusceptible to diseases which can reduce the quality and quantity of the crop. This paper proposes diseasedetection in banana plants using a thermal camera. The detection is carried out using image processingtechniques with multilevel thresholding methods. The image is captured using a thermal camera, then theimage is preprocessed to suit what is desired. After that, so that the position is the same as the image takenusing a digital camera, the image produced by the thermal camera is carried out by an image registrationprocess. The image processing result is compared with the ground truth image obtained from a digitalcamera to determine the effectiveness of the proposed method. The effectiveness of the proposed method ismeasured using the parameters Recall, Precision, F-measure, and Accuracy. The effectiveness of theproposed method is effective enough to produce a recall value of 76.65 percents, Precision 58.38 percents, F-measure64.68 percents, and Accuracy 62.87percents.

Abstract

Making controls for unmanned aircraft is an innovation made to make it easier for someone to learn to control an unmanned aircraft. Advances in technology, especially in the field of control systems, make it possible to perform manual tasks automatically. This control design is designed to facilitate the learning process so that the control process can be carried out at any time. Application of methods in designing hardware and software. This tool uses the Arduino Nano microcontroller as the controller and the nrf24l01 sensor for sending and receiving can be done manually or automatically. From the results of the tests carried out, the nrd24l01 sensor can send and receive according to the specified settings. With this tool, it is hoped that beginners can learn to control unmanned aircraft, which originally required quite a high cost to be able to try and learn manually and now can learn at a lower cost and in a short time. Keywords — arduino nano, Remote Control, Nrf24l01

Abstract

Intisari — Pembangkit Listrik tenaga biomassa adalah pembangkit yang mempergunakan biomassa (Tetes tebu/Molasess) dalam membentuk thermal yang akan dipergunakan untuk menggerakan energi potensial pada sistem pembangkit Listrik. Pada proses pembangkitan listrik ini membutuhkan energi panas yang diproses dari tetes tebu / molasess yang difermentasi dan didestilasi untuk dijadikan bioetanol lalu dipadatkan untuk memanaskan boiler dan dapat memiliki tekanan untuk mendorong steam engine sehingga dapat menggerakan generator sehingga menghasilkan tegangan yang bisa mengisi baterai dan menghidupkan beban. Dari penelitian ini bioetanol padat yang dihabiskan sebanyak 2,1 liter dan menyala selama 199 menit / 3.3 jam sehingga steam engine dapat berputar pada tekanan 10-15 Psi dengan putaran Rpm 161-215 output yang dihasilkan PLTBM ini memiliki tegangan pengecasan 4.1 – 4,2 V dan arus 200-300 mA. Dari tegangan dan arus yang dihasilkan tersebut baterai terisi 100 % dengan kapasitas baterai 1580 mAh/ 1,5 Ah. PLTBM ini juga menggunakan joul thief untuk menyalakan beban lampu 7 watt. Dengan kapasitas baterai 1580 mAh / 1,5 Ah yang terisi 100% beban lampu dapat menyala selama 2,43 jam. Kata kunci— PLTBM ,Bioetanol, Generator, Steam engine Abstract — Biomass power plants are plants that use biomass (sugar cane molasses / molasses) in forming thermal which will be used to move potential energy in the power generation system. In this electricity generation process requires heat energy that is processed from sugarcane molasses / molasses which is fermented and distilled to make bioethanol and then solidified to heat the boiler and can have pressure to push the steam engine so that it can move the generator so as to produce a voltage that can charge the battery and turn on the load. From this study solid bioethanol spent as much as 2.1 liters and lit for 199 minutes / 3.3 hours so that the steam engine can rotate at a pressure of 10-15 Psi with a rotation of Rpm 161-215 the output produced by this PLTBM has a charging voltage of 4,1 - 4,2 V and a current of 200-300 mA. From the voltage and current produced, the battery is 100% charged with a battery capacity of 1580 mAh / 1.5 Ah. This CBM also uses joul thief to power a 7 watt lamp load. With a battery capacity of 1580 mAh / 1.5 Ah which is 100% charged the lamp load can be lit for 2,43 hours. Keywords— PLTBM ,Bioetanol, Generator, Steam engine
