Javanese script is a part of Javanese culture which is owned by Javanese society which should be preserved. One of the efforts to preserve it is by introducing Javanese script in formal education. Javanese language subjects are local content that must be taken by students from grade I to grade VI elementary school students. Javanese script began to be introduced to third grade elementary school students. Javanese script is one of the basic competencies that most students do not understand because most students consider Javanese script a difficult material to learn because of its various forms and complicated writing rules. Therefore, to overcome the above problems, a learning innovation using augmented reality technology is needed. With this application, it is hoped that students can be helped in understanding Javanese script material. Java script learning applications are made using the Waterfall method with the development of augmented reality, namely marker based tracking. The output of this application is that the application will display a video on the smartphone screen that contains learning material for Javanese script. In the black box test results on functional testing obtained a percentage of 99.7%, camera distance testing obtained 66.25% results, camera angle testing obtained 75% results, light intensity testing obtained 100% results. In the usability test results, the Carakan application obtained an adjective rating of 71.54 in the Good category, obtained a grade scale result in the C category, and obtained acceptability ranges in the acceptable category.

Eucheuma cottonii is a type of seaweed that is cultivated in the coastal area of Nagari Sungai Pinang, Koto XI Tarusan District, Pesisir Selatan District, West Sumatra Province. Before being sold, seaweed farmers must dry their seaweed first, because what can be sold is dried seaweed. Drying the seaweed takes two to three days depending on the weather conditions. In this research a seaweed drying system has been designed with a tool that rotates the seaweed in the drying chamber. In this rotary drying system, the soil moisture sensor is used which functions to detect the moisture content of the seaweed, if the moisture content of the seaweed is still read > 30% then the microcontroller turns on the relay which forwards instructions to the heater and the DC motor starts rotating the player container. The DS18B20 sensor is used to detect the temperature of the drying chamber, if the total moisture content of the seaweed is 30%, then the state of dry seaweed has been reached. Tests have been carried out to determine the difference in time required between the seaweed drying process using the system that has been built in this study and the seaweed drying process that utilizes direct sunlight. To achieve a moisture content of 30% in the seaweed drying process with the system designed in this study it takes an average of ±50 minutes, while using direct sunlight it takes ±9 hours to dry the seaweed.

Robot Pembersih Lantai Menggunakan Sensor LM393 dan Ultrasonik Berbasis Arduino Uno

Rina Mardiati — 2022-05-30

Pada era zaman modern saat ini teknologi robot mengalami kemajuan yang sangat pesat khususnya pada robot pembersih lantai. Robot pembersih lantai ini berguna untuk meringankan pekerjaan manusia di bidang rumah tangga. Pada penelitian ini dikembangkan sebuah prototipe robot pembersih lantai dengan menggunakan sensor LM393 dan sensor ultrasonik. Robot ini memiliki fitur alat pembersih sebagai vakum dan alat pel. Sensor ultrasonik digunakan sebagai alat pendeteksi jarak, sedangkan sensor LM393 digunakan sebagai penghitung putaran motor sehingga kecepatan motor stabil sesuai dengan yang diprogramkan pada mikrokontroler arduino uno. Input yang digunakan pada sistem ini adalah jarak dari sensor samping kanan, kiri dan depan yang diperoleh dari sensor ultrasonik. Sementara itu, output dari sistem ini adalah PWM motor DC kiri, PWM motor DC kanan, dan LCD yang menampilkan posisi gerakan robot. Pada penelitian ini dilakukan beberapa pengujian meliputi pengujian modul sensor ultrasonik dan sensor LM393, pengujian kinerja fitur vacum, pengujian kinerja alat pel, serta pengujian sistem secara keseluruhan. Berdasarkan hasil pengujian yang dilakukan terhadap sensitifitas jarak pantul sensor ultrasonik memiliki nilai selisih error 0,898% yang menandakan sensor ini berfungsi dengan baik. Hasil dari pengujian vacum diperoleh bahwa vacum dapat menghisap debu rata-rata 2,4 gram dari lima percobaan yang menunjukkan kinerja vacum cukup baik. Hasil pengujian alat pel dan pengujian keseluruhan menunjukan bahwa selisih error kemampuan robot membersihkan ruangan berukuran 2 m x 2 m dengan bahan kain pel greenwoll ditempuh dalam waktu 4,036 menit sedangkan menggunakan bahan katun adalah 4,31 menit.

ADBR: Accelerated Depth-Based Routing for Underwater Sensor Networks

Abdolreza Andalib — 2022-03-31

It is challenging to propose an efficient routing algorithm for Underwater Wireless Sensor Networks (UWSNs) in terms of packet delivery ratio, end-to-end delay of packet delivery from the source to the destination, and energy consumption. The reasons of that are UWSNs have unique characteristics (e.g. using acoustic channels instead of radio channels for communications), and they have dynamic topology due to the movement of the sensor by the water flow. Depth-Based Routing (DBR) considers one of the well-known algorithms in this context. DBR is a very simple algorithm; however, it is inefficient in terms of packet delivery rate, end-to-end delay, and energy consumption. This study we developed DBR by adding an accelerated routine to it to improve its efficiency, the proposed algorithm; called Accelerated Depth-Based Routing (ADBR). In ADBR, a simple probabilistic mechanism is used to accelerate packet forwarding and provide more multi-path to the destination. In ADBR, each node immediately delivers received packet to the destination with a probability of and follows the DBR routine with a probability of 1 – P_f. The performance of ADBR is evaluated via a set of experiments by using J-SIM simulator. Experimental results indicate the superiority of the ADBR over the DBR algorithm.
