There are many complex data in social networks that can be combined into large data sets which can be accessed. Large amounts of data require more storage and increase the computed summary costs. The need to know how to use data effectively and to extract information from reduced data that has the same information as super data before being reduced. the first thing to do is to convert any unstructured data into structured data utilizing the greedy randomized method, the data can be grouped and combined with other data in its vicinity, and the size of the data can be reduced because the node (user) grouping as a linked pair and is formed the best node around it. This paper presents how to use the minimum description length, as information theory to provide solutions in the model selection problem and apply it in a greedy randomized algorithm that can group unstructured data to reduce data size and provide visualization of the relationship between nodes and how accurate and faster greedy randomized would reduce and combined data into simple link nodes

Keberadaan bidan di tengah masyarakat berperan penting bagi kesehatan ibu dan anak, khususnya balita. Praktik Mandiri Bidan (PMB) Kasih Bunda Bojongsoang, menjadi salah satu klinik kebidanan yang sering dikunjungi pasien ibu dan balita. PMB menyediakan berbagai layanan seperti pemeriksaan kehamilan, USG, persalinan, KB, imunisasi, dan sebagainya. Selama ini, pencatatan dilakukan di sebuah buku yang berisi daftar nama ibu dan anak, dengan pencatatan berulang dan pencarian data yang membutuhkan waktu lama. Pasien tidak mendapatkan data riwayat pemeriksaan dan bukti bayar dari layanan yang diterima. Pengeluaran keuangan klinik juga tidak tercatat secara terperinci. Selain pencatatan data pelayanan dan keuangan, kejahatan yang pernah terjadi di klinik PMB menjadi perhatian khusus, sehingga membutuhkan alat pengawas berupa CCTV. Tim Pengabdian Masyarakat Kolaborasi Internal memberikan solusi berupa kegiatan pengembangan aplikasi pencatatan pelayanan kebidanan dan laporan keuangan berbasis PHP serta monitoring PMB dengan CCTV. Seluruh bidan di PMB sebanyak 100% setuju dan sangat setuju bahwa kegiatan ini memberikan manfaat dan sesuai dengan harapan kebutuhan di PMB

The application and utilization of technology to measure the level of comfort in mass-produced vehicles, including military vehicles, is constantly evolving. Currently, the testing of comfort parameters is carried out manually through human-driven test drives. Thus, the range of variability in measurements is extensive as it depends on the subjective experiential indications of experts. This research utilizes KY-037 sensor to measure noise level and BME280 sensor fusion to detect temperature, air pressure, humidity, and altitude. These parameters have a significant impact on passenger comfort inside the passenger cabin of military vehicles. This project included involves the development of LoRa-based communication medium using RFM95W technology. The system has extensive performance testing inside the passenger cabin of a military vehicle on various test area tracks. The test results indicate that the system is capable of accurately reading the KY-037 sensor, with a range of 80 - 141 dB depending on the tracks. The BME280 sensor consistently measures a temperature of 36,98°C, altitude readings ranging from 667-677 meter above sea level, maintaining a stable air pressure of 955.35 hPa, and measuring the lowest humidity level in the vehicle cabin at 24.34%. The LoRa technology possesses remarkable to extend the communication range, even in challenging environments, reaching distances over 2 kilometers. The response time for data sent in web-based applications consistently remains below 1 second. Thus, this system can assist experts in enhancing cabin passenger comfort standards by narrowing the range and making it more measurable.

Di Sekolah Alam Gaharu terdapat kelas robotika yang dapat mendukumg potensi-potensi dan minat siswa di bidang robotika. Namun saat ini, pengajaran robotika masih menggunakan kit dari vendor, sehingga fitur-fitur dan modul modul yang dapat dieksplore masih terbatas pada yang disediakan vendor saja. Pembelajaran robotika mengakomodir minat dan passion siswa terkait robotika. Guru pengajar robotika masih menggunakan kit robotic dari vendor, dan mengantarkan para siswa ke berbagai ajang lomba robotika. Para siswa ini sering memenangkan perlombaan, baik regional, nasional, maupun internasional. Dengan pembangunan robot mengunakan Arduino, diharapkan dapat meningkatkan skill robotika terutama untuk pengajar sehingga dapat mengembangkan lebih luas dengan para siswa. Potensi lain, para siswa dapat dikenalkan dengan program studi D3 Teknologi Komputer, FIT, Universitas Telkom. Harapan ke depannya, siswa dapat melanjutkan studinya ke Universitas Telkom. Solusi yang ditawarkan adalah penggunaan Arduino untuk robotika dengan memperkenalkan cara kerja sensor dan jenis sensor lain, serta actuator sebagai output. Hal ini sebagai langkah awal untuk pembangunan robotika secara mandiri.

A contributing factor to traffic accidents is brake pad failure, which diminishes braking system performance and extends braking distance. This work develops a prototype utilizing internet of things (IoT) to measure brake pad thickness, hence enhancing driver awareness through real-time monitoring. The system establishes the thickness detection threshold at 75% (3-4 mm) and 50% (5–6 mm) as a cautionary parameter. The thickness parameter employs an American wire gauge (AWG) 18 cable to connect to the ESP32 microcontroller. The web-based IoT monitoring interface employs Laravel. This method enables drivers to get prompt notifications regarding the decrease in brake pad thickness, hence permitting urgent preventative maintenance to mitigate the risk of accidents. The system underwent testing through friction at a rotational speed of 600 to 6,000 rpm. The test findings indicated that the sensor precisely measured the brake pad thickness with a prototype response time of a second. This system is suitable for implementation on old model vehicles that do not have an early warning system. The installation of this technology is anticipated to enhance driver knowledge of the state of the brake pads, hence potentially diminishing the danger of brake system failure caused by unmonitored pad wear.
