Abstract

Meat is one of the essential food ingredients in meeting the nutritional needs. The current problem lies in the consumers' lack of knowledge on how to differentiate between pork, beef, goat, and lamb meat. This is because when the meat is already cut, their appearances may seem similar at first glance. Many consumers are unaware of the practice of mixing different types of meat for consumption. One way to classify animal meat is by using image processing. In this research, an image processing system is created to classify meat, specifically pork, beef, goat, and lamb. Support Vector Machine (SVM) is a development of Machine Learning that can be used in classifying images into specific classes. SVM method as a classifier is performed using a confusion matrix. The test results show the highest accuracy value obtained in the class of Goat Meat 91.4%, the highest precision in the class of goat meat 80%, the highest recall in the class of beef 81.3%, and the highest F1-score in the class of beef 0.76.

Abstract

Transformasi digital dalam dunia pendidikan mendorong perlunya sistem informasi yang mampu mendukung efektivitas pengelolaan kelas dan administrasi oleh tenaga pengajar. Permasalahan seperti beban administratif yang tinggi dan keterbatasan dalam pemanfaatan teknologi menjadi hambatan utama dalam peningkatan profesionalisme guru, terutama di wilayah dengan akses teknologi yang masih terbatas. Oleh karena itu, diperlukan solusi teknologi informasi yang efisien, fleksibel, dan ramah pengguna untuk membantu guru dalam mengelola aktivitas pembelajaran. Tugas akhir ini bertujuan untuk mengembangkan frontend dari aplikasi pengelola kelas berbasis web yang dirancang khusus untuk tenaga pengajar. Sistem ini dibangun menggunakan ReactJS sebagai kerangka kerja antarmuka pengguna, dengan pendekatan pengembangan komponen modular yang mendukung reusabilitas dan skalabilitas. Aplikasi menyediakan berbagai fitur seperti manajemen kelas, pengelolaan tugas, pencatatan jurnal pembelajaran, serta visualisasi data aktivitas guru secara interaktif dan responsif. Antarmuka pengguna dikembangkan dengan mempertimbangkan prinsip user experience (UX) dan user interface (UI) agar mudah digunakan, intuitif, serta dapat diakses dari berbagai perangkat. Hasil pengembangan menunjukkan bahwa sistem frontend yang dibangun mampu memenuhi kebutuhan tenaga pengajar dalam mengelola aktivitas kelas secara digital. Diharapkan dengan adanya sistem ini, tenaga pengajar dapat terbantu dalam mengurangi beban administratif, meningkatkan efisiensi pengelolaan kelas, serta mendukung profesionalisme dalam proses pembelajaran berbasis teknologi.

Abstract

CDMA is interference limited multiple access system. Because all users transmit on the same frequency,internal interference generated by the system is the most significant factor in determining system capacity andcall quality. The transmit power for each user must be reduced to limit interference, however, the power shouldbe enough to maintain the required Eb/No (signal to noise ratio) for a satisfactory call quality. Maximumcapacity is achieved when Eb/No of every user is at the minimum level needed for the acceptable channelperformance. As the MS moves around, the RF environment continuously changes due to fast and slow fading,external interference, shadowing , and other factors. The aim of the dynamic power control is to limittransmitted power on both the links while maintaining link quality under all conditions. Additional advantagesare longer mobile battery life and longer life span of BTS power amplifiers.In this research will be made a sumulation of power control and multi user detection to avoid the interferencebetween MS.Observations show that the increasing number of users will decrease the value of Signal to Interfrence Ratio(SIR) / SIR below the target. To cope the growing number of users increases can be done by iteration / updatingpower transmit so the convergence computation can be reached and target value SIR can be achieved. Inaddition, to reduce interference can also be done by extending the number of chips.
