Abstract

Cahaya Mandiri Audio, an electronic service provider, is currently facing operational challenges due to its reliance on a manual record-keeping system, which has resulted in a data error rate of 15% and difficulties in maintaining customer loyalty. This study aims to design and build a web-based Customer Relationship Management (CRM) system capable of integrating customer data management, service history, and technician scheduling to optimize operations and improve customer retention. The development method used is the Prototype approach, utilizing the PHP programming language and the Laravel framework. The results of the study indicate that this system successfully unifies the roles of Admin and Technician within a single integrated platform, thereby minimizing human error and creating a more organized workflow compared to the previous manual system. The contribution and novelty of this system lie in the Scheduled Notification Module via WhatsApp, which facilitates the semi-automatic creation of message drafts through a redirect feature based on unit service history data to efficiently enhance customer loyalty.Keyword: CRM, Service, Laravel, Customer Loyalty, WhatsApp API.

Abstract

An aquarium serves as a container designed to house and display various aquatic organisms and elements. For aquascape enthusiasts, maintaining cleanliness and stable environmental conditions within the aquarium is essential to preserve the beauty and health of both fish and aquatic plants. However, using water cleaners alone is insufficient, as temperature is a crucial factor that affects the comfort and survival of aquatic organisms. Considering that Indonesia experiences two distinct seasons, which can cause fluctuations in water temperature, a system capable of automatically controlling the temperature is required. This research aims to design a Water Temperature Control System for Aquarium Fish Using a Temperature Sensor Based on Arduino Uno. The system is developed to help aquascape hobbyists maintain a stable water temperature without manual intervention, allowing the temperature to automatically adjust according to the needs of the fish. The Arduino UNO microcontroller serves as the main component, integrated with a DS18B20 temperature sensor, a mini fan, and a push button. The temperature data detected by the DS18B20 sensor are displayed on an OLED LCD screen, which is programmed using the Arduino IDE. This system enables efficient and accurate water temperature regulation, ensuring a stable environment that supports the well-being of fish and aquatic plants within the aquarium.
