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

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.

Abstract

This study compared the accuracy and efficiency of capacitive and resistive soil moisture sensors within an Internet of Things (IoT) based automated irrigation system in a smart garden case study.Irrigation automation by factors such as soil moisture sensors reliable as required, is a critical determinant in efficient water use.The paper uses the ESP32 based IoT irrigation framework to evaluate performance of two soil moisture sensors: capacitive and resistive. The operational efficiency, as well as the difference in total cost is also looked at.Smart gardens were used in this paper to record over three months (from July until September) dynamics of soil humidity, as well as the consumption of water. The cloud-based database saved in real-time per sensor response on one hand information, and then further statistical data every hour about pump activation frequency and total water discharge.Conclusions drawn from quantitative analysis are: Resistive sensor performance has some major problems, such as excessive sensitivity to changes in soil conductivity and a drift tendency over time. This causes Irrigation pump false alarms to occur frequently. Conversely, the capacitive sensor offered readings with more stable repetition and smaller variation.The results show that, compared to the resistive-based system, the system with capacitive sensors reduced cumulative water consumption by 30%. This implies that although resistive sensors may have a lower initial cost, the long-term water use efficiency which can be attained with capacitive sensors easily compensates for any disadvantages in performance they may have and makes their installation the best choice for sustainable IoT-based precision agriculture applications.

Abstract

Creativity plays a crucial role for students because it provides various benefits that support their overall development, both in academic and personal aspects. This study aims to: 1) determine the learning motivation of fifth-grade elementary school students, 2) determine the creativity of fifth-grade elementary school students, and 3) determine the influence of learning motivation on the creativity of fifth-grade elementary school students. This research method uses a quantitative method with an ex-post facto design. Data collection was carried out through a learning motivation questionnaire and creativity observation sheet. The questionnaire instrument is used to obtain data on students' learning motivation. Observation sheets are used to determine students' creativity. Data were collected through a learning motivation questionnaire and a creativity observation sheet. Data analysis techniques consist of prerequisite tests and hypothesis tests. The prerequisite tests consist of normality tests and homogeneity tests. Hypothesis testing uses a t-test with the help of the IBM SPSS Statistics 22 program. The results of this study indicate the influence of learning motivation on the creativity of fifth-grade elementary school students in batik making with a p-value of 0.000 < 0.05. The conclusion of this study confirms that learning motivation has a significant influence on the creativity of fifth-grade elementary school students.
