Abstract

Toko Mulia Pancing is a small and medium business that provides a wide selection of goods and tools for fishing. Financial management processes such as recording transactions and processing stock data are still done manually so errors often occur. This website, named "Kasir muliaPancing", aims to overcome this problem by providing a barcode scanning feature, storing sales report data and stock reports. The system was built using the PHP programming language with the CodeIgniter Framework and MySQL database. The results of this research are a website that can only be accessed at two levels, namely admin as owner and user as cashier. On the website there is a menu to store supplier, customer, product, transaction, invoice, and report data. Where each menu has its own function which aims to make it easier for users to make transactions. Website testing uses the black box testing method which produces output as expected   Keywords— Cashier, Website, Barcode Reader, Mulia Pancing Shop

Abstract

The development of Internet of Things (IoT) technology enables real-time and efficient measurement and monitoring of electricity consumption. This study aims to design and develop an IoT-based electricity consumption monitoring and control system equipped with a prediction feature using the Long Short-Term Memory (LSTM) algorithm. The system uses the PZEM-004T sensor to measure electrical parameters such as voltage, current, power, and energy, which are then transmitted via the MQTT protocol using an ESP32 microcontroller. Electricity consumption data is displayed on a mobile application and stored in a Supabase database. In addition to monitoring features, the system also provides control over electrical devices through a relay, as well as user-configurable scheduling and consumption limit settings. The electricity consumption prediction feature is developed to provide estimated monthly bills or estimated time until prepaid electricity tokens run out, based on historical data. The implementation results show that the system is capable of performing real-time monitoring and control, as well as providing informative visualizations of consumption history in graphical form. This system is expected to help users manage their power consumption more wisely and efficiently.

Abstract

With the increasing volume of online shopping, the need for a secure and reliable package storage system has become more critical. To address issues such as loss, damage, and failed deliveries due to the recipient's absence, a Smart Box system based on the Internet of Things (IoT) was designed using an Arduino Nano microcontroller and an ESP32-CAM module. This system enables automatic locking and unlocking of the box through barcode scanning and is equipped with a camera to document the package reception process. The ESP32-CAM module also sends notifications and images to the package owner via a Telegram bot. Test results show that the system can accurately read barcodes and successfully send photos and notifications through Telegram. It can be concluded that this IoT-based Smart Box is secure and feasible to be implemented as a solution to enhance the safety and autonomous management of package storage.

Abstract

Pengembangan robotika telah mendorong inovasi di berbagai bidang, termasuk olahraga. Dalam golf, mengumpulkan bola secara manual memakan waktu dan tenaga. Penelitian ini merancang robot pengumpul bola golf semi-otomatis untuk mengatasi masalah tersebut. Robot ini dilengkapi sensor inframerah FC-51 untuk mendeteksi bola berdasarkan pantulan cahaya, sensor ultrasonik HC-SR04 untuk menghindari rintangan, dan kamera ESP32-CAM sebagai sistem penglihatan. Kontrol utama menggunakan mikrokontroler ESP32 yang diprogram dengan Arduino IDE, dan sistem ini terintegrasi dengan aplikasi Telegram untuk notifikasi. Dalam pengujian di lapangan simulasi 1x1 meter, robot berhasil mendeteksi dan mengumpulkan bola dengan efektif. Prosesnya stabil dengan waktu rata-rata 20–25 detik per bola. Sistem ini menunjukkan potensi besar untuk meningkatkan efisiensi latihan dan mengurangi beban kerja. Temuan ini menjadi fondasi untuk pengembangan robot pengumpul bola yang lebih canggih dan adaptif, yang dapat digunakan di lapangan golf yang lebih luas di masa depan.
