As an institution engaged in SMK Muhammadiyah 03 Yogyakarta requires network infrastructure as a medium of communication. Infrastructure in SMK Muhammadiyah based VLAN but still using static routing and star topologies as a medium of communication between router. This leads to the main router performance overburdened which makes the network infrastructure down. It is necessary to reform the network, especially in the communication protocol on the router by using protocol Open Shortest Path First(OSPF). OSPF is a link state-based routing protocol that uses Dijkstra’s algorithm to find the best path is taken as a communication medium. Makin paths made by considering various aspects of the parameters that affect network traffic. OSPF can minimize down on network infrastructure caused by the buren of a huge traffic to maintain the stability of traffic on communication lines. The results using the method QOS on infrastructure with the OSPF protocol can be classified very nice. It is obtaine from the measurement parameter delay <150 ms, packet loss (0%), an bandwidth has a very goo category based on the standard TIPHON. From the results of the QOS parameters also obtained a decrease in delay value by 31% on infrastructure with the OSPF protocol. This proves that the network traffic is more stable when using OSPF protocol.

The development of information and communication technology could not be separated from the development of computer network and interconnected network (internet). On the other side, there are people who try to access the information illegally, even try to disturb and destroy the flow of information. These people are called hacker or cracker. Because of that reason, it is needed tools to prevent this information. Those tools are like firewall, IPS (Intrusion prevention system), IDS (intrusion detection system), anti-virus, and other tools. This research does literature review by analyzing one of IDS tools that is honeypot using a method of data analyzing using secondary data from Honey net Project Research at January 7th until 29th 2003. The result published by those researchers is a DDOS attack was happen at January 18th and 19th 2003 that caused one of the computer servers with IP (internet protocol) 10.1.1.101 went down at January 19th 2003. A computer with IP 10.1.1.101 at January18th 2003 started to get over packets, that is 293 packet or 41.1% from 707 packets, but the computer had not gone down yet. However, at January 19th 2003 the computer got more packets, that was 795 packets or 58% from 1,370 packets, that cause the computer became down. The evidence was unconnected computers at January 20th 2003. Based on these analyzing we concludes that honeypot is very effective to be a supporting tool to detect a network intrusion, especially DDOS. And the addition value of honeypot implementation is a log which gives information for network administrators to know any activities on the network, both normal activities, or disadvantage activities.

The cooling system has an important role in the quality of machining results, the cooling fluid (air/fluid) are developed to be able to reduce heat and friction arising from the formation of the product, but also environment-friendly. The use of natural oils has been tested in various machining conditions with a minimum quantity lubrications (MQL) method, including the addition of materials that can improve fluid convective properties. Cooling performance with natural materials results in surface roughness according to product smoothness requirements according to ASTM classification and is able to maintain a low tool temperature and reduce chatter/tools vibration. Improvement of the MQL process, temperature, and compressed air pressure conditions determine cooling performance, the lower the compressed air temperature will increase the fluid's ability to reduce tool temperature and increase durability and tool life. The process of forming steel with high hardness requires a cooling system with special conditions. The properties of natural oils will be enhanced by the convective thermophysical properties by the addition of Titanium Oxide (TiO2), CuO and Aluminum Oxide (AL2O3). Natural oils used in the study are corn oil, sunflower oil, water with the addition of nanoparticles. The formation of nanofluids uses magnetic stirrer with varying time and rotation speed, and % weight ratio. The MQL System is equipped with cold air from the compressor which is cooled by utilizing the evaporation/refrigeration process which is kept constant at 10oC. The cooling system is equipped with a microcontroller/interface to keep the air temperature/pressure constant. In this paper the data presented is a study of cooling in the hard milling process to determine the most nanofluid/dominant factors that affect the results. The results showed that the use of cutting fluids reinforced by nanoparticles in natural oils in a minimum amount increased lubrication properties. There is a significant effect on the use of cooling fluid types with surface roughness, fluids with high lubrication properties, significant to reduce surface roughness, cutting temperature and power consumption. The nanofluid prove was able to apply in an environment-friendly manufacturing process very promising.

The Rigidity, absorption resistance, and vibration damping are important factors for the formation of static components and structures with excitation force loads. The development of new materials from composites for metal substitution has achieved better properties. The use of rocks with reinforcement CNTs can produce higher damping properties than metal casting, but young modulus is low. The Composite polymer material made from volcanic rock can be cast with epoxy with a variation of the aggregate ratio using compressive press able to improve mechanical properties. The volcanic rocks used in this study are granite, silica, and volcanic sand, using carbon nanotubes MW-CNTs as reinforcement. This research was conducted to produce structures with high strength and rigidity. The material are classified dimensions coarse (0,2-0,5 mm), medium (20 Î¼m-50 Î¼m), and fine (0.125mm/0.50 mm). Based on SEM/EDX test results of granite, silica, and volcanic sand have high silica content (with the sharp crystalline form that has the potential to strengthen the composite bond. The fly ash has high silica content, with round and fine crystals form. The specimen formation method refers to the dimensions of the composite specimen bending test according to ASTM D 645. The combination of materials that warns hardness and elongations, in separate tests of volcanic sand and granite which has the highest hardness, the use of CNTs can increase the hardness of 15% in each specimen, increase bending testing at 220% to 300%, prove that the inside of the crystalline bond forms ductile properties.
