Abstract

The Modern Annida Islamic Boarding School is one of the pesantren located in South Lampung Regency. The teaching and learning process in this pesantren integrates the national curriculum with additional religious studies. However, at the Modern Annida Islamic Boarding School, the interest of students at the senior high school (SMA) level remains lower than that of students at the junior high school (SMP) level. Senior high school students are perceived as lacking sufficient competencies to be workforce-ready. Digital Graphic Design is a form of visual communication that presents information, products, or services through digital interfaces. Simply put, digital graphic design is specifically created for use on computers. Several methods can be applied to train students in digital graphic design at schools, including discussions, demonstrations, experiments, problem-solving, and lectures. By utilizing a Digital Graphic Design approach, the aim is to make education at the senior high school level in the Modern Annida Islamic Boarding School more engaging and less monotonous, with the hope that junior high school students will be encouraged to continue their education at the senior high school level within the institution. In this training, students are not only introduced to basic photo editing techniques using Adobe Photoshop but are also encouraged to develop creativity, which is highly essential in today's digital era. This program successfully sparked the students' interest in exploring their talents in graphic design, which could potentially become a source of income in the future.

Abstract

The rapid expansion of e-commerce has increased the demand for secure and efficient package delivery solutions, particularly for recipients who are frequently away from home. This study presents the development of a Smart Package Receiver Box, an Internet of Things (IoT)-based system that integrates sensors and remote control functionalities to enhance package security. The system incorporates an ESP32-CAM microcontroller, an ultrasonic sensor for courier detection, a PIR sensor for package counting, and a solenoid door lock for secure access control. These components are integrated with the Telegram messaging application, enabling real-time notifications, visual monitoring, and remote control of package deliveries. Experimental testing demonstrates that the system reliably detects couriers within a 5 cm to 30 cm range, accurately counts inserted packages, and ensures a secure locking mechanism with prompt response times. The collected data confirm stable system performance, minimal delays, and effective remote accessibility for users. Despite its advantages, the system presents certain limitations that warrant further improvements. The current implementation lacks encrypted communication, posing potential security vulnerabilities that could be mitigated by integrating AES-256 encryption and secure authentication protocols. Additionally, the system's reliance on Telegram makes it susceptible to disruptions in service availability, necessitating the incorporation of alternative communication channels such as SMS notifications or cloud-based APIs. Future enhancements will focus on strengthening data security, increasing system redundancy, and conducting comprehensive field testing to improve robustness and scalability for broader adoption in modern package delivery systems.

Abstract

Pertanian greenhouse konvensional seringkali menghadapi tantangan inefisiensi akibat ketergantungan pada pengendalian manual dan tingginya variabilitas kondisi lingkungan. Untuk mengatasi hal tersebut, studi ini menyajikan metode pemodelan suhu udara berbasis Decision Tree yang dirancang khusus untuk optimalisasi smart greenhouse. Penelitian ini bertujuan untuk menciptakan sistem pengelolaan suhu yang presisi dan tangguh (robust) dengan memanfaatkan integrasi jaringan sensor nirkabel dan analitik data. Metodologi penelitian meliputi akuisisi data lingkungan, pra-pemrosesan data yang ketat, serta pelatihan model untuk memprediksi fluktuasi suhu. Hasil evaluasi menunjukkan bahwa algoritma Decision Tree mengungguli model komparasi lainnya, dengan capaian akurasi tertinggi sebesar 85,52%. Selain akurasi, penelitian ini juga berhasil mengimplementasikan model tersebut ke dalam sistem tertanam (embedded system), memungkinkan prediksi real-time sebagai mekanisme cadangan (fail-safe) saat sensor fisik mengalami gangguan. Penelitian ini memberikan kontribusi signifikan terhadap efisiensi sumber daya, optimalisasi hasil panen, serta keberlanjutan praktik pertanian modern. Studi lebih lanjut disarankan untuk mengeksplorasi teknik Deep Learning dan validasi jangka panjang guna meningkatkan performa adaptif sistem.
