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

Red guava is one of the crops from the Pamijahan sub-district, Bogor Regency. The current system is considered ineffective in terms of marketing, especially during a pandemic like this, buyers/customers want the convenience or speed of relevant information to facilitate all their activities without having to leave the house. The Covid-19 virus makes people anxious and afraid to leave the house. In dealing with this problem, researchers designed an Android-based mobile application with the prototype method to facilitate ordering or selling red guava transactions and conducting technology-based marketing. Meanwhile, the system uses the Unified Modeling Language in the analysis and design phase. From the test results, the system performance is running well.

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;

Abstract

The purpose of this study is to analyze the wireless signal quality of an access point (AP) with a focus on the types of obstacles that could potentially affect network performance. The use of wireless technology has become essential in sustaining modern civilization, especially in environments with various types of machines such as walls, electronic devices, and electromagnetic machines. The analysis method involves measuring and adjusting the signal quality at several points that indicate conditions that could be affected by the use of non-reversible mesh. The signal strength, transmission speed, and connection handling at each observation point were analyzed. Finally, the analysis results were used to identify the type of wireless signal work and the impact of different types of obstacles. The results of this study provide insight into how certain types of obstacles can affect wireless signal quality at access points. These findings can aid in the development of strategies to improve and enhance wireless network performance, including recommendations for optimizing access point placement or using interference mitigation technologies.

Abstract

Kuliah kerja nyata merupakan salah satu kegiatan untuk syarat wisuda setiap mahasiswa di Universitas Ibn Khaldun Bogor. Selama kurang lebih 30 hari, mahasiswa melakukan pendekatan dengan masyarakat dan merencakan program-program kerja di Desa Kalong I Kecamatan Leuwisadeng. Masyarakat di Desa Kalong I merupakan masyarakat yang beragam (heterogen) sehingga program-program kerja disesuaikan dengan kondisi dan potensi yang ada. Pendidikan, teknologi, kesehatan, dan ekonomi merupakah salah satu faktor penting yang dapat mempengaruhi kehidupan masyarakat Desa Kalong I. Sebanyak 16% masyarakat Desa Kalong I masih mengemban dunia Pendidikan dan sisanya merupakan masyarakat dewasa yang berdagang. Namun, minimnya fasilitas yang memadai untuk meningkatkan pengetahuan mereka, membuat mereka kurang mendapat literasi terhadap pentingnya membaca, mempelajari ekonomi perdagangan, ilmu kesehatan, dan teknologi. Pembangunan Taman Baca Masyarakat (TBM) ini merupakan salah satu pendekatan yang dapat meningkatkan multi disiplin di masyarakat. Pada TBM ini, tersedia buku-buku dari berbagai bidang seperti bidang agama, pendidikan, ekonomi, dan pengetahuan umum.
