Abstract

Antlion habitat that breeders create currently does not use a system that can protect the habitat from changes in temperature and humidity. In addition, when they are about to be sold, breeders filter and sort the antlion one by one. Therefore, a system is made that can monitor and control changes in temperature and humidity as well as harvesting automatically through the application. This system is designed using a wireless sensor network with temperature and humidity sensors DHT22, IR MLX90614 with soft actuators and mist makers as well as loadcell sensors to trigger off the sieving motor connected to the Firebase database and interface Flutter application. Based on the results of testing the accuracy of temperature, humidity, infrared, and loadcell sensor readings, respectively, they are 98.07, 97.58%, 98.38%, and 98.78% with an average delay of 216,97ms can maintain temperature changes in the range 24-30? and humidity in the range 70-80% stably. And the average value of harvest time is 30.37 seconds with an average decrease in sand load of 56.7 grams when the harvesting mechanism is running.

Abstract

Internet access is so easy that every level of society can access information from the website. If internet access is used positively, it will produce positive things for its users as well. Such as the facilities provided by the management of SMK Al-Mahrusiyah Lirboyo. Students, especially in the Computer and Network Engineering (TKJ) department, get facilities such as PCs in the lab or laptops along with internet access during productive learning hours. In its application in schools, students who are given laptop facilities and internet access do not always use it for learning. Questionnaire data showed that there were other things that were opened, including 37.7% of respondents finding and trying hacking tutorials, 35.8% playing social media, and 34% streaming movies. For this reason, a firewall is needed that restricts students' access to it. The firewall will be formulated with a script on the MikroTik router through the WinBox. The results of firewall tests using a combination of filters and Raw successfully blocked access to social media websites, streaming movies, and anime. The client cannot access and the display in the client browser displays continuous loading. Testing firewalls to ward off DoS attacks was also successful. When tested, LOIC did not send a single request packet and when the CPU resource was checked, the resource was only 1%. The use of firewalls with MikroTik routers is effective in limiting students' access to other things outside of learning. With this, it is hoped that students can better utilize facilities for learning.

Abstract

Salinity is the key parameters in the shrimp culture environment. Conventional method is by visiting each pond plot. But,due to the large number and distance between the plots, this method is less effective. This ineffectiveness can lead to less than optimal yields. Manet is applied to increase the effectiveness of checking salinity using the BATMAN routing protocol. In this study, 2 units of laptops were used that act as Node 1 and Node 4, 2 units of Orange Pi Zero as Node 2, and 3. Each device is connected to a conductivity sensor to measure the salinity. The four devices are configured with an adhoc network using the BATMAN routing protocol. This research was conducted to provide an alternative for monitoring salinity to make it more effective. Based on the results of testing and analysis of network quality, the average delay value is 22.285 ms. The low delay value affects the percentage of packet loss in the four test scenarios with an average percentage of 0.999759613 %. Memory and CPU usage in testing 4 transition scenarios resulted in an average memory usage of 0.225% and CPU usage of 0.725%. The BATMAN routing protocol does not use a lot of memory and CPU usage because it only forwards data packets without the need to process data. From these data, it can be concluded that manet with batman routing protocol can be used as an alternative communication to provide communication network services in areas where there is no fixed network infrastructure.

Abstract

Majelis taklim merupakan salah satu lembaga pendidikan non formal yang memiliki kontribusi besar dalam mengembangan dan pembinaan ilmu agama Islam. Majelis taklim di Indonesia sudah berkembang pesat dalam masyarakat, mulai dari anggotanya yang sedikit hingga yang anggotanya mencapai ribuan. Salah satu majelis taklim yang turut andil di Kecamatan Kedung Kandang adalah Majelis Taklim Al-Qur’an “Tsamrotul Iman”. Kegiatan rutin majelis taklim meliputi pengajian mingguan, perayaan hari besar keagamaan, maupun khatmil Al-Qur’an membutuhkan perangkat audio yang baik. selama ini, perakitan dan operasional sistem audio tersebut masih dibantu oleh pihak luar, bukan dari anggota majelis taklim. Akibatnya, terjadi ketergantungan dengan pihak luar yang menambah biaya operasional majelis. Pada pengabdian ini dilaksanakan pelatihan perakitan dan operasional sistem audio pada Majelis Taklim Al-Qur’an Tsamrotul Iman, Kecamatan Kedung Kandang, Kota Malang. Adanya pelatihan dan penataan sistem tata suara ini meningkatkan kualitas suara yang dihasilkan sehingga menambah kenyamanan anggota dalam melakukan kegiatan rutin.

Abstract

In this paper we study electronic driving license (EDL) for secure sharing of vehicles in wireless IoT networks. The process of authentication and data transmission to the server is a very challenging problem to solve. To solve this problem, we propose the use of a wireless IoT network to overcome the transmission speed from the vehicle to the server, and the use of EDL for the driver authentication process. Two devices are installed on the vehicle side and on the server side while the wireless IoT network is used to make data transmission efficient. EDL is used to authenticate drivers who rent vehicles. When the device authentication process on the vehicle will send geographic information obtained through the global positioning system (GPS) to the server. The server will verify the user, if it matches then the server will send a command to the vehicle to be used. To run the considered system, we proposed Algorithm 1 and 2 to run the vehicle device and server, respectively. Experiment result shows the proposed system has maximum accuracy in 95.5%, packet delivery ratio 90%, delay propagation less than 60 seconds. Thus, the security of the shared vehicle will be increases.

Abstract

Pada artikel ini, kami mempelajari tentang sistem pembiakan ulat hongkong otomatis berbasis Markov Decision Process (MDP) dengan komunikasi wireless internet of things (IoT), dimana program cerdar berbasis MDP ditanamkan pada sebuah mikrokontroller sehingga dapat memengatur suhu dan kelembaban optimal berdasarkan input dari sensor. Sistem ini dikembangkan dengan mempertimbangkan proses pembiakan ulat hongkong yang tidak optimal dikarenakan kelembaban dan suhu ruangan yang berubah secara dinamis. Untuk menyelesaikan masalah ini secara efisien, kami menanamkan algoritma MDP pada mikrokontroller, dimana mikrokontroller mendapatkan parameter masukan dari sensor DHT22 sehingga dapat menentukan suhu dan kelembaban optimal dengan mengontrol sinar UV, kipas dan pompa air. Selain itu, dengan menggunakan komunikasi wireless IoT, system pembiakan ulat hongkong ini dapat dipantau oleh pengguna dengan jarak jauh. Hasil eksperimen menunjukkan sistem yang diusulkan dapat menurunkan rata-rata ulat hongkong yang mati sebesar 54%.
