Abstract

Data security on a network infrastructure is a very sensitive and vulnerable matter. One alternative to overcome this is to use IPS (Intrusion Prevention System) technology where the technology is a development of IDS (Intrusion Detection System) which uses Snort. In this study, IPS technology is applied using the Untangle Firewall where the Intrusion Prevention feature is available on the platform with the intention of testing the feature on the Untangle Firewall. Testing was carried out using DoS (Denial Of Service) and SSH Brute Force attacks where the Intrusion Prevention feature on the Untangle Firewall can recognize both attacks and can block the attacks using manually added rules.

Abstract

Background. Entrepreneurs utilize abundant raw materials by making coconut husk, which is the main ingredient in making coconut husk brooms. However, many still use conventional methods to process it, such as pounding it until it becomes fiber. Aim. To be carried out effectively, it is deemed necessary to have technological assistance, such as the Coconut Husk Shredding Machine. Methods. However, to ensure that the aid has improved the effectiveness of the coconut husk shredding process, it is necessary to analyze and compare the time motion study between the two methods. By comparing the Standard Time between the two methods, Result. We can determine the extent of the difference, allowing us to quickly estimate the amount of product produced from coconut husk shredding within a specific time frame or how long it takes to process the available amount of coconut husk. Conclusion. The research and time motion study analysis results in an activity of shredding coconut husks using conventional methods and machines, which aligns with the hypothesis that shredding coconut husks using machines is 2.91 minutes faster than traditional methods. Implication. This work time measurement recommendation can be used as a standard time measurement in shredding coconut husks using conventional and machine methods.

Abstract

Making combined materials that consist of unsaturated polyester and coconut fiber is the target of this research. The samples were tested by tensile and hardness tests before and after warm-up, and obtained by the result was that the trend value of hardness of unsaturated polyester+coconut fiber experienced proportional degradation with the addition of the composition of coconut fiber. The composition of 3% coconut fiber+97% unsaturated polyester has the highest hardness value, reaching 46,7 kg/mm2, and downhill becomes 43,1 kgf/mm2 moment heated at a temperature of 500C for 1 hour. Analog to the tensile test, 3% coconut fiber + 97% unsaturated polyester composition has the highest ultimate tensile strength and yield point. Adding fiber can boost the elasticity modulus, but the warm-up treatment causes the expansion of coconut fiber. The result is that the value of the tensile and hardness of the polyblend will go downhill.
