Treatment Planning System (TPS) is a computerized radiation therapy treatment plan using special software with the aim of maximizing the dose to the target (cancer) and minimizing the dose to the surrounding normal tissue. One way to minimize radiation dose to healthy tissue is to create a homogeneous distribution of radiation dose in areas with uneven surfaces such as the neck by utilizing a wedge filter. Researchers compared the results of TPS with varying wedge angles ranging from 15o, 30o, 45o, and 60o and assessed the effectiveness against cancer based on the isodose curve, in cases of laryngeal cancer. From the results of this comparison, the use of a 15o wedge is considered less effective because the radiation dose distribution does not cover the entire larynx. The use of a 30o wedge is considered effective because the maximum radiation dose distribution covers the entire larynx. The use of a 45o wedge is considered ineffective because the maximum radiation dose distribution is found in almost all organs in the neck. The use of a 60o wedge is considered ineffective because the dose distribution in the neck has a radiation dose of above 110% or even 125%. From the results of the comparison of wedge angle variations, an angle of 30o is considered the most effective so that it can be used for implementing the Treatment Planning System in the field.

Currently, the government is increasingly building PLTMG to fulfill the electricity needs of the society. Beside for fulfill the electricity needs of the Indonesian people, PLTMG also has a negative impact on the society, especially for the community around the PLTMG in the city of Batam. So companies need to conduct studies on environmental impacts, one of which is the impact of the air produced on the surrounding area. The PLTMG industry does not use air pollution control devices, but uses a leanox combustion control system on each gas engine with a chimney outlet that emits SO2 and particulate emissions. The model simulation was carried out using Aermod view software with meteorological data from the affected locations. The results of AERMOD modeling show that the PLTMG industry will have an impact on particulate emissions in the ambient air around the activity location which will spread to the northwest, north, south and east of the activity location. The Aermod Model also shows that current conditions have resulted in dispersion with concentrations below the maximum limit stated in the 2021 Government Regulation. The addition of an emission monitoring system such as CEMS can be used to help monitor the concentration of dispersed emissions. Apart from that, emission control devices such as incinerators or combustion can also be used to reduce the concentration of the emissions used.

This journal reviews the use of Cisco simulators in building and analyzing ring topology networks and the routing protocols used in them. Ring topology is one of the commonly used network topologies where all nodes are directly connected to form a circle. The routing protocol in ring topology uses Bellman Ford and Dijkstra algorithms to determine the best path. The main focus of this research is on Enhanced Interior Gateway Routing Protocol (EIGRP), a routing protocol developed from Interior Gateway Routing Protocol (IGRP). EIGRP enables fast convergence and efficiency in data transmission in the network. The research methods used are literature and simulation methods using Cisco Packet Tracer software.
