Abstract

Kehidupan manusia modern khususnya yang tinggal di daerah perkotaan Indonesia biasa mendapatkan air yang disediakan oleh PDAM. PDAM bertugas mendistribusikan air bersih dari berbagai jenis sumber air hingga dapat dinikmati oleh pelanggannya. Adapun sistem pencatatan penggunaan air pelanggan masih dilakukan secara manual. Petugas PDAM setiap bulannya datang ke rumah pelanggan untuk mencatat jumlah penggunaan air berdasarkan indikator meteran air analog yang terpasang di rumah pelanggan kemudian hasil pencatatan diinputkan ke sistem pascabayar. Penerapan sistem pascabayar tidak efisien karena rentan kesalahan. Dibutuhkan sebuah teknologi yang mampu membantu pekerjaan PDAM dengan sistem otomatisisasi guna meningkat efisiensi. Penerapan Teknologi IoT merupakan sebuah solusi karena setiap meteran air dapat terhubung dengan pihak PDAM sehingga dapat dilakukan manajemen kontrol. Sistem prabayar lebih cocok diterapkan karena pelanggan dapat mengatur penggunaan airnya sendiri tergantung dari saldo pulsa air yang dibeli. Didapatkan hasil bahwa sistem telah bekerja dengan baik berdasarkan pengujian yang dilakukan pada fitur yang tersedia.

Abstract

Vending Machine atau mesin penjual otomatis merupakan suatu alat yang dapat menjualkan produknya secara otomatis seperti makanan, minuman, mainan, dan lain-lain. Pada sistem pengoperasian Vending Machine saat ini masih membaca manual penghasilan dari setiap unit dan tidak bisa melihat stok yang tersisa didalam Vending Machine secara online, yang mengakibatkan kurangnya efisiensi kerja petugas yang membawa stok makanan lebih menuju Vending Machine dan pada sistem pemabayaran yang digunakan saat ini masih menggunakan uang kertas, dimana metode ini masih belum efektif dikarenakan saat melakukan transaksi pelanggan tidak bisa menerima uang kembalian dan tidak semua uang kertas bisa terbaca oleh mesin dikarenakan kondisi uang yang berbeda. Oleh sebab itu di buatkannya prototipe ini dengan menambahakan Teknologi IoT atau Internet of Things kedalam Vending Machine, dimana sistem yang akan dibuat dapat melihat data transaksi, data stok dan data penjualan tiap bulannya secara online melalui website maupun telegram dan merubah sistem pembayaran yang sebelumnya menggunakan uang kertas kini menggunakan kartu, agar pelanggan tidak perlu menyiapkan uang pas atau memilih uang yang masih bagus untuk melakukan transaksi. Disimpulkan dengan penerepan Teknologi IoT atau Internet of Things dapat memiliki keuntungan dari pihak pengelola maupun calon pelanggan saat melakukan transaksi.

Abstract

The use of a face as a biometric to identify a person in order to keep the system safe from an unauthorized person has advantages over other biometric characteristics. The face as a biometric has more structure and a wider area than other biometrics, while can be retrieved in a non-invasive manner. We proposed a cloud-based architecture for face identification with deep learning using convolutional neural network. Face identification in this study used a cloud-based engine with four stages, namely face detection with histogram of oriented gradients (HOG), image enhancement, feature extraction using convolutional neural network, and classification using k-nearest neighbor (KNN), SVM, as well as random forest algorithm. This study conducted a classification experiment with cloud-based architecture using three different datasets, namely Faces94, Faces96 and University of Manchester Institute of Science and Technology (UMIST) face dataset. The results from this study are with the proposed cloud-based architecture, the best accuracy is obtained by KNN algorithm with an accuracy of 99% on Faces94 dataset, 99% accuracy on Faces96 dataset, 97% on UMIST face dataset, and performance of the three algorithms decreased in UMIST face dataset with facial variations from various angles from left to right profile.

Abstract

Beringkit Animal Market is one of the large traditional animal markets in Bali which is famous for selling superior cows. In addition to selling superior cows, Beringkit Animal Market also sells dogs and various types of poultry such as chickens, ducks and roosters. However, in the midst of the COVID-19 outbreak, traditional markets are considered as the main cluster for the spread of COVID-19 due to the large number of interactions between buyers and traders. The implementation of Community Activity Restrictions (PPKM) has resulted in a lack of income for traders at the Beringkit Animal Market. This study aims to design an Android-based online animal auction application as a medium for buying and selling animals to minimize physical interaction between buyers and traders, the online auction transaction process is chosen because the auction transaction process can bring together traders and buyers in the same online media and make offers up to reach the highest agreed price. The research method applied is the DSRM method or Design Security Research Method, application development uses Android Studio to develop mobile applications, and uses Visual Studio Code to develop web-based systems. Data storage and web server management in this study using MySQL and Laravel. The results of this study are in the form of an Android-based animal auction application that can be used as a medium for transactions between buyers and traders who have gone through the blackbox testing process with the test results as expected.

Abstract

This research aims to design and implement an IoT-based automated fish feeding and dosing system to improve the efficiency of the feeding process through automation. The components used include the ESP32 microcontroller, RTC sensor, ultrasonic sensor, voltage sensor, stepper motor, LCD, DC motor, and relay. The system performs dosing and feeding based on user-defined schedules. Based on the research results, the system successfully monitors and controls the dosing and feeding process of the fish automatically. However, the overall success rate of the system is only 70%, with an average error rate of 1.36% for the voltage sensor and 1.33% for the ultrasonic sensor. The battery experiences an average hourly decrease of 0.19V during system operation. The system faced challenges such as relying on Wi-Fi connection to connect to the Firebase server, insufficient battery capacity, and the unreliability of the stepper motor for dosing purposes.
