Abstract

Rice is a staple food for most Indonesians. The growing population, which has already reached 278 million, is expected to lead to increased rice consumption. Therefore, it is important to have a system that can forecast rice production. Time series data can be used to forecast rice production. Two common time series forecasting methods are linear regression and polynomial regression. Linear regression is used for data that is linear, while polynomial regression is used for data that is non-linear. In this study, we evaluated the performance of linear regression and polynomial regression for rice production forecasting in West Nusa Tenggara Province from 2001 to 2022. The results showed that the polynomial regression model with 4-degree gave better results than the linear regression model. The RMSE and MAE for the polynomial regression model were 0.48 and 2.34, respectively, while those for the linear regression model were 0.97 and 0.87, respectively. The results of this study suggest that the polynomial regression model with 4-degree is a better choice for rice production forecasting in West Nusa Tenggara Province

Abstract

Artikel ini membahas tentang konsep dasar arsitektur dan organisasi komputer, jenis-jenis arsitektur komputer yang umum digunakan, serta pentingnya pengetahuan tentang arsitektur dan organisasi komputer dalam pengembangan sistem komputer. Konsep dasar meliputi struktur fisik sistem komputer dan cara sumber daya sistem digunakan untuk menyelesaikan tugas tertentu. Jenis-jenis arsitektur komputer yang dibahas meliputi arsitektur Von Neumann, arsitektur Harvard, arsitektur RISC, dan arsitektur CISC. Arsitektur RISC dan CISC adalah dua pendekatan yang berbeda dalam merancang instruksi dan set instruksi dalam arsitektur komputer. Arsitektur RISC juga cenderung menggunakan register-register yang lebih banyak, sehingga mengurangi ketergantungan pada akses ke memori utama.Di sisi lain, arsitektur CISC menggunakan set instruksi yang lebih kompleks dan beragam. Instruksi-instruksi dalam arsitektur CISC dapat melakukan tugas yang lebih kompleks dalam satu instruksi, seperti operasi aritmatika yang kompleks atau akses langsung ke memori. Set instruksi CISC biasanya lebih besar dan beragam, termasuk instruksi-instruksi yang jarang digunakan. Meskipun instruksi-instruksi dalam arsitektur CISC dapat lebih kompleks, eksekusi instruksi biasanya membutuhkan lebih banyak siklus dan waktu.Kelebihan arsitektur RISC termasuk eksekusi instruksi yang lebih cepat dan efisien, konsistensi dalam ukuran dan format instruksi, serta ketergantungan yang lebih rendah pada memori utama. Arsitektur RISC juga cenderung lebih mudah diimplementasikan dalam perangkat keras dan memungkinkan pipelining yang efisien. Namun, kelemahan arsitektur RISC adalah jumlah instruksi yang terbatas, yang mungkin memerlukan lebih banyak instruksi untuk melakukan tugas yang kompleks.Sementara itu, kelebihan arsitektur CISC termasuk kemampuan untuk melakukan tugas yang kompleks dalam satu instruksi, dukungan untuk instruksi-instruksi yang jarang digunakan, dan ukuran kode yang lebih kecil. Arsitektur CISC juga dapat mengurangi jumlah instruksi yang diperlukan untuk melakukan tugas yang kompleks. Namun, kelemahan arsitekturCISC adalah kompleksitas eksekusi instruksi yang dapat mempengaruhi kinerja, serta ketergantungan yang lebih besar pada memori utama.Dalam praktiknya, kedua arsitektur ini memiliki aplikasi yang berbeda dalam sistem komputer modern. Arsitektur RISC cenderung digunakan dalam perangkat berperforma tinggi yang membutuhkan eksekusi instruksi yang cepat, seperti dalam superkomputer, server, atau mikrokontroler.

Abstract

An entrepreneur or a service provider in the internet network world, will certainly find clients with different characters. Clients who are not technology blind, especially routers, sometimes want full access to the router, or some clients who ask to add a router to be able to directly access the router in full. Virtual Router allows clients to process their own network, as if the client has a router. Network forensics has the ability to reconstruct events using a system that stores all data traffic activities on the network, so that investigations can be carried out by looking back at events that have occurred and analyzing events that occurred in the past. Wireshark can review data packages in real time. This means that the wireshark application will monitor all incoming and outgoing data packets through a predefined interface and the next will display the results of the data package
