<![CDATA[Pest can be a serious topic in agricultural areas especially rice plantations. The pest destroys the plants before harvesting time. Because of the presence of the pest, the yield of agricultural products is decreasing. From a technical point of view, an agricultural professional should identify not only the type of pest that destroys rice plants but also overcome the pest. This research proposes a paper review on pest detection systems by using Blockchain technology and the Internet of Things involving all parties involved. The use of the review is to have a broad overview regarding the functional combination between IoT and Blockchain technologies to reduce the pest problems. Smart contract technology Blockchain may be held to determine automatic alert in the system and know how to resolve the problem accurately and all information is verified by blockchain system without a human interception. IoT devices can be attached to rice plantations to monitor, determine and send the information of the pests. Our paper explains the combination of IoT and Blockchain technologies in order to improve any possibility of success rate by getting the pests. Thus, IoT replaces human manual checking in pest identification to reduce human error. So that, the harvesting time can be increased and the agriculture yields are good. The search comparison results show that ScienceDirect has the highest search value]]>

<![CDATA[Era Digital saat ini memiliki dampak besar bagi kelestarian alam, selain mengurangi penggunaan kertas dengan adanya berkas berbentuk file membuat arsip yang tersimpan lebih tertata rapih dengan kurun waktu yang lama. Di masa pandemi pemanfaatan digital menjadi peran penting dalam kelangsungan kehidupan yang mengharuskan kegiatan tanpa harus kontak langsung. Dengan begitu banyak pekerjaan pekerjaan yang diselesaikan dirumah kemudian dibantu dengan Internet untuk melakukan proses kirim/terima file. File merupakan data yang sudah diolah menjadi sebuah informasi berupa teks, video, gambar, dan suara. Dalam proses pengiriman tidak jarang terjadinya kendala yakni ukuran file terlalu besar karena media penyimpanan yang digunakan hanya sedikit. Kompresi data adalah ilmu yang menampilkan informasi dalam bentuk yang pendek tujuannya untuk mengurangi jumlah bit yang digunakan untuk menyimpan atau mengirim informasi. Sedangkan Algoritma Huffman adalah teknik kompresi yang tidak mengubah informasi data dari aslinya. Prinsip kode Huffman yaitu karakter yang paling sering muncul di dalam data dikodekan dengan kode yang jumlah bitnya lebih sedikit, sedangkan karakter yang jarang muncul dikodekan dengan kode yang jumlah bitnya lebih panjang. Kompresi file dibutuhkan untuk mempercepat proses pengiriman data antar jaringan komputer. Perkembangan teknologi saat ini menyebabkan kebutuhan data serta perpindahan data dari satu perangkat ke perangkat lain meningkat. Data-data tersebut umumnya dikompresi terlebih dahulu agar proses pertukaran tidak memakan waktu yang lama. Dengan menggunakan algoritma huffman Rasio Kompresi yang dihasilkan untuk file audio dan image rasio kompresi yang dihasilkan lebih kecil sedangan untuk file teks rasio kompresi yang dihasilkan lebih besar. Tingkat keamanan data setelah dikompresi tidak berkurang atau mengalami kerusakan setelah proses kompresi data dilakukan Kecepatan proses kompresi dan dekompresi data setara dengan ukuran dan jenis file. File hasil dekompresi akan berhasil seperti file semula sebelum dikompresi, kecepatan proses kompresi dan dekompresi data setara dengan ukuran dan jenis file dan Kompresi file juga kurang berhasil jika isi file terlalu sedikit sehingga ukuran file asli bisa jadi lebih kecil dari file hasil kompresi karena file kompresi masih harus menyimpan huffman tree-nya.]]>

<![CDATA[ACC (Adaptive Cruise Control) is a crucial technology to control the automatic driving of a vehicle, which can automatically adjust the driving status of the vehicle according to the driving status of the vehicle in front so that the vehicle always keeps a safe distance from the vehicle in front, which can primarily relieve the driver's driving pressure and avoid tailgating. The research is of great significance to the realization of intelligent driving of vehicles. In this paper, the fuzzy PID control method is used to study the vehicle ACC system. Firstly, the basic concept and key components of the ACC system are explained, the vehicle longitudinal dynamics model is established, and the primary ranges of , and parameters are determined through simulation; based on this, the fuzzy PID control algorithm of vehicle ACC is designed considering three different driving conditions of fixed speed and following cruise mode. The fuzzy PID control algorithm of the vehicle ACC system is designed and established. The joint simulation model of MATLAB is used to simulate the vehicle ACC system under three different driving conditions. The simulation results show that the vehicle ACC system designed in this paper ensures the safety and stability of following the vehicle while providing the vehicle's ride's comfort.]]>

<![CDATA[This paper will focus on the application of machine vision in mobile robots and take moving to the appropriate position and grasping the designated target as the task. This paper will describe and simulate the vision technology that mobile robots need to apply in the task process. This paper mainly uses the camera as the sensor. The difficulties of vision technology are mainly divided into three parts: scene depth information acquisition, positioning and mapping, and image processing. In order to obtain the depth information of the scene, this paper mainly introduces the depth information acquisition methods of monocular camera and binocular camera. In the aspect of localization and mapping, this paper mainly introduces the simulation of visual odometer to understand the basic process of mobile robot obtaining navigation map and its own route. Then, the gray gradient 2D maximum entropy algorithm is introduced to segment the scene and target, and extract features to judge the required target. Compared with other segmentation algorithms, the gray gradient 2D maximum entropy algorithm has higher segmentation accuracy, but the operation time is longer. This paper has simply optimized its operation efficiency. Finally, this paper describes the positioning method of grasping the object with a two degree of freedom manipulator using the knowledge of inverse kinematics. Because of the epidemic situation, schools cannot obtain experimental equipment. This paper mainly demonstrates the effectiveness of the algorithm through simulation.]]>
