Abstract

Penggunaan zat pewarna buatan pada makanan secara berlebihan dapat berdampak buruk terhadap kesehatan manusia. Pewarna alami merupakan alternatif yang dapat digunakan sebagai pengganti pewarna buatan. Salah satu zat warna alami yang bisa digunakan yaitu antosianin yang berwarna merah keunguan dan banyak terdapat pada tanaman di Indonesia, salah satunya yaitu rosella. Penelitian ini bertujuan untuk mengetahui pengaruh temperatur terhadap kinetika ekstraksi antosianin menggunakan pelarut larutan etanol dalam air. Penelitian ini juga mengkaji beberapa model kinetika ekstraksi untuk mengetahui model mana yang paling cocok terhadap kinetika ekstraksi antosianin. Rasio massa antara umpan dan pelarut sebesar 1 :  50 dengan kecepatan pengadukan konstan sebesar 200 rpm. Temperatur yang digunakan yaitu 30oC, 45oC, dan 60oC untuk menghindari kerusakan antosianin, dan diperoleh konstanta laju ekstraksi sebesar 0,017 , 0,020 , dan 0,032 menit-1. Kinetika ekstraksi antosianin menggunakan larutan etanol mengikuti perilaku model kinetika linear seperti yang diusulkan oleh Spiro dan Jago.

Abstract

The need for reliable and extensive network infrastructure in a military environment, especially in Jasdam II Sriwijaya, is becoming increasingly important along with the security tasks and challenges faced. This research aims to design a network that meets military standards and performance by applying the Top-Down method. The Top-Down method in the context of network design, along with network needs analysis in a military environment. Through this approach, this research aims to strengthen operations and expand the network in Jasdam II Sriwijaya. The research methodology includes data collection on network needs, needs analysis, Top-Down design, implementation, and testing. The expected results of this research are the design of a network structure at 3 locations that are in accordance with well-defined military needs, as well as expanding network communications in a military environment, measuring how well the network is using the QoS method. This research provides optimal network infrastructure development in JASDAM II Sriwijaya, with the potential for a wider scale.
