Teknologi pesawat tanpa awak semakin banyak diminati oleh para peminatnya. Permasalahan yang sering muncul pada pesawat tanpa awak semacam quadcopter adalah sistem keseimbangan dan mekanisme pengambilan objek yang ada saat berada diudara. Dalam keadaan terbang diam (Hold) baisanya quadcopter akan terombang ambing dikarenakan banyak faktor. Bisa karena perbedaan putaran motor ataupun faktor angin. Sedangkan untuk objek hanya bisa diambil dari satu arah saja. Agar permainan ini semakin menarik, penelitian ini akan memperbaiki dan menyempurnakan sistem balancing dan sistem monitoring pesawat tanpa awak (quadcopter).

The problem that is often faced today is when we travel out of a room and we forget to turn off electronic devices in the room which results in a surge in costs that must be paid for wasteful use of electronic goods, in this modern era many ways can be done to make automatic system that aims to help human work, in this system the author makes a system that can save electricity usage. By using the PIR sensor to detect movement, and if there is movement inside the room then the electronic goods will live and, if the user wants to use power without having to turn off automatically, then the user can use the RFID card to be affixed to the electronic goods will continue to live until the card is removed from the RFID module, and the buzzer will sound if the user attaches the card to the RFID module incorrectly, to make it easier for the user to see the current conditions, then install the LCD to make it easier for the user to know the current condition.

ABSTRACK In its development, the essay exam features become an obstacle, because the increase in the number of students and the number of examinations results in the teacher taking the time to assess the answers to the exam questions. In general, the answer correction system for essay answers is done manually, so the use of e-learning and without e-learning in terms of time efficiency there is no difference. Therefore, an automatic assessment system is needed on essay examinations to accelerate the process of evaluating student answers. Automated essay scooring is an automatic scoring system by comparing two answers and then calculating the results of a comparison using an existing algorithm. One algorithm used is the Jaro-Winkler Distance algorithm, which is to measure the similarity between two strings. In this research, an automated essay scoring system integration is based on the Jaro-Winkler Distance algorithm, so that with an automated scoring essay system, it can help the teacher in the essay answer correction process. The results of the system testing show, the assessment of the answers generated by the system is influenced by whether or not there is a key term in the answer sentence. The more different the number of words in a sentence between teacher and student, the smaller the resulting value. If a student's answer sentence has a key term distribution which is the same as the teacher's answer key then the resulting value is also higher.

Traditional Magnetic Induction Tomography (MIT) systems demonstrate limited spatial resolution and detection sensitivity when analyzing complex conductivity distributions in biological tissues. This research investigates the integration of Nitrogen-Vacancy (NV) centers in diamond substrates to overcome these fundamental limitations. The primary objectives include: (1) developing a quantum-enhanced MIT system with superior magnetic field detection capabilities, (2) quantifying performance improvements in spatial resolution and sensitivity compared to conventional approaches, (3) validating system effectiveness through controlled phantom studies and biological tissue analysis, and (4) establishing technological foundations for next-generation medical imaging applications. This study presents the first comprehensive implementation of quantum sensing technology in tomographic imaging applications. Novel contributions include: development of an integrated NV-center based magnetic field detection system, achievement of 0.8 mm minimum detectable feature size representing 3.5-fold resolution enhancement, demonstration of 0.01 S/m conductivity detection threshold showing 10-fold sensitivity improvement, and validation of 62% reconstruction error reduction with 28% structural similarity enhancement. The quantum-enhanced approach establishes new paradigms for early disease detection and precision medicine applications, providing unprecedented imaging capabilities for medical diagnostics, material characterization, and geophysical exploration. Results demonstrate transformative potential for clinical implementation with 95% sensitivity and 92% specificity in detecting sub-millimeter tissue anomalies

Pemberian subsidi pupuk merupakan langkah penting dalam mendukung produktivitas pertanian dan kesejahteraan petani. Penelitian ini bertujuan untuk menerapkan metode Weighted Product (WP) sebagai alat bantu dalam menentukan penerima pupuk subsidi secara objektif dan terukur. Metode WP dipilih karena kemampuannya untuk menangani berbagai kriteria penilaian dengan memperhitungkan bobot kepentingan setiap kriteria. Dalam penelitian ini, beberapa kriteria penilaian seperti luas lahan, produktivitas tanaman, dan kebutuhan pupuk digunakan untuk mengevaluasi alternatif petani. Data petani dinormalisasi dan dihitung menggunakan rumus WP, dengan hasil akhir menunjukkan nilai untuk setiap petani. Hasil analisis menunjukkan bahwa petani nomor 5 memperoleh nilai tertinggi sebesar 0.120. Nilai ini menandakan bahwa petani nomor 5 adalah alternatif yang paling optimal untuk menerima pupuk subsidi berdasarkan kriteria yang telah ditetapkan. Penelitian ini menggarisbawahi efektivitas metode WP dalam membuat keputusan distribusi subsidi yang adil dan berbasis data. Implementasi metode ini tidak hanya menjamin transparansi tetapi juga memfasilitasi pengalokasian sumber daya yang lebih efisien. Rekomendasi untuk ke depan termasuk pembaruan berkala pada bobot kriteria dan data untuk mencerminkan perubahan kebutuhan dan prioritas serta penerapan metode ini pada bidang-bidang lain yang memerlukan pengambilan keputusan berbasis kriteria.

Banyaknya tindakan yang terjadi dalam pencurian informasi atau data karyawan seperti usemame serta password asal suatu akun atau data-data penting disebabkan sang hacker karena tidak adanya perlindungan terhadap aspek confidentialit pada suatu jaringan komputer. Tujuan dalam penelitian ini adalah untuk menganalisa keamanan jaringan wireless di Kantor PTPN III Kebun Bandar Selamat terhadap packet sniffing dan untuk mengevaluasi keamanan jaringan wireless di Kantor PTPN III Kebun Bandar Selamat terhadap packet sniffing. Tingkat keamanan yang diterapkan pada website PTPN III Kebun Bandar. Selamat. Seperti yang diketahui tingkat kearnanan bukan hanya berasal dari aplikasi website PTPN III yang sudah ada namun keamanan website PTPN III Kebun Bandar Selamat juga dapat dilihat pada saat proses komunikasi data antara client dengan web server pada jaringan. Keamanan website PTPN III Kebun Bandar Selamat masih perlu peningkatan yang terbukti pada hasil percobaan sniffing pada aplikasi Wireshark masih ditemukannya paket data berisi informasi penting seperti username dan password pada saat melakukan login, akses domain name server (DNS) yang dituju serta informasi Iainnya.
