Abstract

Layanan pengisian air galon konvensional masih menghadapi berbagai kendala, seperti ketidaktepatan volume pengisian, kesalahan transaksi, serta keterbatasan pencatatan histori layanan secara waktu nyata. Penelitian ini mengusulkan sistem pengisian air galon otomatis berbasis Internet of Things (IoT) yang mengintegrasikan autentikasi pengguna menggunakan Radio Frequency Identification (RFID), pengukuran volume secara presisi, dan pencatatan transaksi real-time. Sistem dirancang menggunakan mikrokontroler ESP32, sensor infrared E18-D80NK untuk deteksi keberadaan galon, sensor flowmeter YF-S201 untuk pengukuran volume air, serta modul RFID MFRC522 untuk verifikasi pengguna dan pemotongan saldo otomatis. Data volume dan transaksi disimpan pada server lokal dan dapat dipantau melalui antarmuka web secara waktu nyata. Pengujian dilakukan pada kapasitas 5 liter sebanyak 30 kali pengulangan dengan rentang debit 1–3 L/menit. Hasil pengujian menunjukkan deviasi pengukuran volume sebesar ±0,47%, akurasi deteksi galon mencapai 100%, dan validitas transaksi RFID sebesar 100%. Temuan ini membuktikan bahwa sistem yang dikembangkan mampu meningkatkan efisiensi, akurasi, dan keandalan proses pengisian air galon serta mendukung penerapan konsep Internet of Things dalam digitalisasi layanan publik secara berkelanjutan.

Abstract

Encouraging the use of the independent curriculum emphasizes flexibility and student-centered learning. The development of a contextual e-module provides a solution to facilitate relevant and interactive mathematics learning, particularly in statistics for eighth-grade students. This e-module is designed based on students' daily experiences, making the material easier to understand and promoting independent learning. The research method used is Research and Development (RD) with the 4D model (Define, Design, Develop, Disseminate). Validation results from the subject matter and media experts indicate that the contextual e-module in mathematics learning on statistics for eighth grade is valid. Practicality tests through teacher and student response questionnaires show highly practical results, with average scores of 3.6 and 3.5 on a maximum practicality scale of 4.0. In conclusion, the contextual e-module in mathematics learning on statistics for eighth grade has proven valid and practical for use in mathematics education and can serve as an effective and relevant learning resource tailored to students' current needs and conditions.

Abstract

Liquefaction occurs when soil that was previously stable and solid suddenly loses its strength and stiffness within a short period. This research develops a model for testing soil liquefaction using a 1-g shaking table. The system, based on LabVIEW, is designed to measure and analyze the performance of foundations during soil liquefaction tests. It enables the evaluation of soil characteristics before, during, and after an earthquake that could induce liquefaction, while also considering foundation reinforcement. In this study, the Ziegler-Nichols PID tuning method was employed to improve control accuracy and stability during seismic vibration simulations and to measure soil bearing capacity. The results indicate that the system achieved a rise time of 8 seconds, a delay time of 13 seconds, an overshoot of 0.06%, a settling time of 13 seconds, and a steady-state error of 0.02%. Compared to the Trial Error method, the Ziegler-Nichols method achieves faster rise time, delay time, and settling time but results in higher overshoot and steady-state error. The sensor data provides detailed information about the helical pile's ability to support vertical loads, with an average bearing capacity of 3.99 kPa.
