<![CDATA[The growth of Internet users and services such as video streaming and big data application make particular problems in the core network such as the depletion of IPv4 allocation, delay, and jitter. MPLS as technology in the core network is used for anticipating delay problems due to data traffic improvement on the Internet. To anticipate the growth of Internet users and the depletion of IPv4 allocation as an address to access the network, it needs the new version of IP that is IPv6 with a bigger amount of address allocation. The incorporation of those addressing mechanisms in the core network needs a particular method to exchange data between devices. This research compares two translation methods between 6PE and 6VPE in the MPLS-VPN network. The result of measurement of throughput shows that the use of the 6VPE method provides better efficiency of network used 15% than 6PE in the data rate of 2000 Kbps. The experiment is done by comparing the two methods in the MPLS-VPN network with only using the IPv4 addressing mechanism where the service used is video streaming.]]>

<![CDATA[Sebuah sistem operasi yang dapat di pindah-pindahkan atau dengan kata lain portabel yaitu sebuah sistem operasi yang di simpan di media penyimpanan seperti flasdiks. Cukup dengan menancapkan flashdisk di PC/Laptop lalu melakukan setting bios untuk usb-boot priority, jadilah komputer tersebut dengan “sistem operasi pribadi” yang siap digunakan untuk berbagai keperluan. Berbeda halnya dengan sistem operasi tertanam (embedded system) adalah tujuan khusus sistem komputer yang didesain untuk melakukan satu atau lebih fungsi tertentu, yang bergantung pada komputasi real-time. Biasanya embedded system merupakan bagian peralatan yang lengkap termasuk hardware dan bagian mekanik. Jelasnya, computer untuk tujuan umum, seperti personal computer (PC), dapat melakukan tugas yang berbeda tergantung dari program yang tersedia. Embedded system dapat mengatur lebih banyak peralatan yang biasa dipakai saat ini.]]>

<![CDATA[The problem of manual trash cans causes a lack of hygiene for users and scattered garbage due to the volume of garbage bins that have accumulated. Paper and tissue waste is the dominant waste in the campus area and is highly flammable. Due to the lack of manual trash cans, innovation ideas were obtained to make automatic room trash cans and can monitor waste capacity and detect smoke using smartphone applications as the application of the Internet of Things (IoT). The IoT-based smart trash can uses the NodeMCU 8266 as its main control and ultrasonic sensors to detect the distance of the garbage capacity and the distance of the object. Servo motor as a drive for the garbage lid automatically. MQ-2 smoke sensor as a smoke marker, a warning sound through the Buzzer and also the Wifi ESP 8266 module so that it can send notifications via the internet network. Trash cans can be monitored using the Blynk application. The results obtained in this study are that the trash can cover will automatically open when the object is 10cm to 1cm from the trash can. The results of the sensor detection of the full capacity level of the waste are when the garbage is 5cm to 1cm from the sensor. Furthermore, the results of the detection of the MQ-2 sensor, when the smoke capacity exceeds 325ppm, the buzzer will turn on and the system sends a notification message using a Blynk to the cleaning staff's smartphone.]]>

<![CDATA[The development of Information Technology has become increasingly rapid. Many agencies or companies that have used information systems for operational processes that manually become an automated and integrated system. One of which is a parking system. In Indonesia there are still many vehicle day care stations that use a parking system manually. This makes the parking attendant unfamiliar with the price set and the lengths of time parked the vehicle and make it difficult in the process of calculating the report of parked vehicles. For this reason, an integrated parking system is needed so that it can be applied to manual vehicle storage. So in making the parking system uses the concept of programming. The concept of the program to be used is the concept of Object Oriented Programming with the Java programming language and the editor uses Netbeans 8.2 to run the program. The method in conducting this research is to use 2 methods, namely the method for collecting data with the description method and the method for developing a waterfall system. With the parking system will provide convenience for parking users and also make efficient parking attendant performance. So expect speed, and accuracy in collecting vehicle parking at a vehicle storage in Indonesia. ]]>
