Abstract

Penggunaan kunci pintu konvensional di ASPIKA sebagai alat bantu untuk mengakses ruangan dinilai memiliki tingkat keamanan yang rendah karena anak kunci dapat diduplikat oleh siapapun sehingga orang yang tidak memiliki hak akses atas pintu tersebut juga dapat mengakses pintu. Selain itu penggunaan pintu konvensional juga tidak dapat memantau waktu akses pintu sehingga penghuni dapat mengakses pintu kapanpun melewati batas waktu yang telah ditetapkan oleh pengurus ASPIKA yaitu jam 9 malam. Berdasarkan permasalahan yang ada maka dibuatlah sebuah alat sistem otomatisasi dengan memanfaatkan RFID sebagai pengganti anak kunci dan electromagnetic doorlock sebagai pengunci pintu otomatis. Pada penelitian ini juga dibangun sebuah website untuk memonitoring aktivitas akses pintu di ASPIKA. Adapun tahapan penelitian yang digunakan dalam peelitian ini adalah pendekatan, pengembangan, implementasi dan pengujian. Hasil pengujian meliputi pengujian fungsi RFID, pengujian fungsi electromagnetic doorlock, pengujian fungsi LCD i2c, pengujian fungsi push button dan pengujian website. Kesimpulan dari penelitian ini ialah pintu dapat terbuka secara otomatis dengan mendekatkan RFID tag ke RFID reader. Hasil pemantauan waktu akses pintu dapat diakses pada website yang telah dibangun.

Abstract

In recent years, there has been a growing interest in analyzing Customer Lifetime Value (CLV) due to its ability to provide valuable insights into customer profitability and worth. CLV analysis predicts the net profit attributed to the entire future relationship with a customer. This analysis involves calculating the present value of a customer's expected future spending with the company, facilitating an understanding of the economic value of long-term customer relationships. CLV analysis empowers businesses to identify their most profitable customers and develop strategies for retaining them, ultimately maximizing long-term profitability. CLV analysis relies on various models and techniques, including the RFM analysis categorizes customers based on recency, frequency, and monetary value, helping to segment customers and predict future behavior. Then, The Pareto/NBD model combines probability distributions to estimate CLV and is commonly used for customer base analysis. This research article explores the application of RFM analysis for estimating customer lifetime value using the Pareto/NBD model in an online retail dataset. This metric is crucial for businesses as it assists in identifying valuable customers and formulating retention strategies to maximize long-term profitability.

Abstract

Abstract: In agriculture, irrigation systems are vital for enhancing water management and maximising plant growth. Effective irrigation management involves distributing sufficient quantities of water evenly to condition soil fertility for plants. This study aims to design a prototype that can be monitored via the Telegram app. The research methodology employs a thinking framework approach. The system is implemented using an Arduino Uno microcontroller and supporting devices, including an ESP8266 Wi-Fi module, an ultrasonic sensor, a soil moisture sensor, a stepper motor and a servo motor. Telegram serves as the monitoring tool, sending notifications connected to the Arduino via a Wi-Fi network. Test results showed that the system operates effectively: the HC-SR04 ultrasonic sensor functions as a water level reader, and the stepper motor opens and closes the water gate. Soil moisture monitoring uses a soil moisture sensor to measure the water content in the soil. If the sensor detects dry soil conditions or a moisture level below 60%, the servo motor will rotate 15° to close the water channel. Conversely, if the sensor detects wet or moist soil conditions, the servo motor will rotate 0° to close the water channel. Keywords: arduino uno; irrigation system; soil moisture; ultrasonic sensor;
