Configuration and Visualization of Spanning Tree Protocol (STP) for VLAN-Based Using Packet Tracer
No full textIn this era of globalization, scientific and technological progress is increasing, and so is the company we work with, the PT. Telkom Rivai. The company has discovered that computer networks are essential especially because they use and manage the kind of Local Area Network (LAN). Most LAN problems are the absence of a backup link and frequent looping in switch devices that make the internet network inactive or stop functioning. This problem can be resolved by breaking the cycle using the Spanning Tree Protocol (STP) approach. Since there are no restrictions on access between divisions, it allows unauthorized or unidentified people to access data at the company. As a solution, we propose configuring and visualizing a Virtual Local Area Network (VLAN) with access privileges for each division. The last problem is data leakage for every division, which can be fixed by restricting access to certain regions of the division by activating Access List Control on the router

Distributions of Rare Earch Element (REE) in Mangrove Surface Sediment by Nuclear Technique
No full textThe Juru rivers are highly industrial, urbanized and agricultural. The aim of the study was to examine the geochemical bases and enrichment of rare earth elements in Juru mangrove sediments. This study is carried out to investigate the concentrations of rare earth element (REEs) elements Samarium (Sm), Europium (Eu), Yttrium (Yb), Lutetium (Lu), and Terbium (Tb) present in surface mangrove sediments of Juru River, West Coast of Peninsular Malaysia. The concentrations of rare earth elements in the sediments were determined by using the instrumental neutron activation analysis (INAA) method. For calibration and quality control procedures, standard reference material SL-1 and blank samples were irradiated together with sediment samples. The degree of anthropogenic impact on sediments were computed using enrichment factor. The concentration and enrichment factor of all the REE elements ranged between 0.42 mg/kg (Lu), 7.55 mg/kg (Sm), 0.77 (Lu) and 2.96 (Tb), respectively. The geochemical behavior of REEs in surface sediments and normalized patterns (chondrite and shale) have been studied. These findings indicate that the level of pollution has not reached an extreme or severe level, but ongoing studies should be carried out on the inputs of anthropogenic activities at Juru river
