Di dalam komunikasi Voice over Internet Protocol (VoIP) mengenal beberapa macam protocol tambahan selain protocol standar internet Transfer Control Protocol/Internet Protocol (TCP/IP), beberapa diantaranya adalah protocol Session Initation Protocol (SIP), Inter-Asterisk eXchange (IAX) dan H.323. Performansi perlu dijaga mengingat VoIP mempunyai kemungkinan melakukan berbagai cara kompresi untuk menciptakan efisiensi saluran dan pemilihan protocol yang tepat. Teknologi VoIP pada dasarnya tidak memiliki jaminan keamanan pada setiap komunikasi. Keamanan ketika melakukan komunikasi suara merupakan sesuatu yang sangat penting karena menyangkut privasi penggunanya. Penggunaan Virtual Private Network (VPN) merupakan salah satu solusi untuk menutup celah keamanan pada kasus di atas. Analisis yang dilakukan pada artikel ini adalah performa yang dihasilkan VoIP yang menggunakan protocol IAX dan SIP. Penelitian ini mengahasilkan kesimpulan bahwa performansi yang paling baik digunakan untuk membangun sistem komunikasi VoIP adalah protocol IAX dengan menggunakan sistem keamanan VPN Point to Point Protocol (PPTP) dikarenakan nilai Quality of Service (QoS)Â lebih tinggi daripada protocol SIP dan juga terbukti lebih aman saat diterapkan sistem keamanan Virtual Private Network Point to Point Protocol (VPN PPTP).

Underwater environment poses a difficult challenge for autonomous underwater navigation. A standard problem of underwater vehicles is to maintain it position at a certain depth in order to perform desired operations. An effective controller is required for this purpose and hence the design of a depth controller for an unmanned underwater vehicle is described in this paper. The control algorithm is simulated by using the marine guidance navigation and control simulator. The project shows a radial basis function metamodel can be used to tune the scaling factors of a fuzzy logic controller. By using offline optimization approach, a comparison between genetic algorithm and metamodeling has been done to minimize the integral square error between the set point and the measured depth of the underwater vehicle. The results showed that it is possible to obtain a reasonably good error using metamodeling approach in much a shorter time compared to the genetic algorithm approach.

Chronic hyperglycemia and acute glucose fluctuations are the two main factors that trigger complications in diabetes mellitus (DM). Continuous and sustainable observation of these factors is significant to be done to reduce the potential of cardiovascular problems in the future by minimizing the occurrence of glycemic variability (GV). At present, observations on GV are based on the mean amplitude of glycemic excursion (MAGE), which is measured based on continuous blood glucose data from patients using particular devices. This study aims to calculate the value of MAGE based on discrete blood glucose observations from 43 volunteer patients to predict the diabetes status of patients. Experiments were carried out by calculating MAGE values from original discrete data and continuous data obtained using Spline Interpolation. This study utilizes the machine learning algorithm, especially k-Nearest Neighbor with dynamic time wrapping (DTW) to measure the distance between time series data. From the classification test, discrete data and continuous data from the interpolation results show precisely the same accuracy value that is equal to 92.85%. Furthermore, there are variations in the MAGE value for each patient where the diabetes class has the most significant difference, followed by the pre-diabetes class, and the typical class.

The widespread use of computer experiments for design optimization has made the issue of reducing computational cost, improving accuracy, removing the “curse of dimensionality” and avoiding expensive function approximation becoming even more important. Metamodeling also known as surrogate modeling, can approximate the actual simulation model allowing for much faster execution time thus becoming a useful method to mitigate these problems. There are two (2) well-known metamodeling techniques which is kriging and radial basis function (RBF) discussed in this paper based on widely used algorithm tool from previous work in modern engineering design of optimization. An integral part of metamodeling is in the method to sample new data from the actual simulation model. Sampling new data for metamodeling requires finding the location (or value) of one or more new data such that the accuracy of the metamodel can be increased as much as possible after the sampling process. This paper discussed the challenges of adaptive sampling in metamodel and proposed an ensemble non-homogeneous method for best model voting to obtain new sample points.

Solar panels have constraints on output power that are not large enough and they are highly depend on natural conditions. Solar panel power depends on the intensity of sunlight received and the temperature of the surrounding environment. In order to get the maximum output power of the solar panel, an additional device called the solar tracker is needed. This research has contributed to increasing the output power of solar panels by directing solar panels perpendicular to sunlight. The use of this research is very useful in the application of the multi-axis tracker application from the sun. By knowing the rising angle of the sun every morning and the circulation angle to sunset, the tracker will work quickly so that the energy used for movement is very small. The reference angle generated by the ANFIS training algorithm is more accurate because the calculated data will be confirmed again by the sensor. And this system can work offline, without being connected to a data center, so it can be used in remote or isolated areas.Keywords : Sun Tracking System, MPPT, ANFIS, Solar Panels AbstrakPanel surya memiliki kendala pada daya keluaran yang tidak cukup besar dan sangat tergantung oleh kondisi alam. Daya panel surya sangat tergantung dari intensitas cahaya matahari yang diterima dan suhu lingkungan sekitar. Agar mendapatkan daya keluaran panel surya yang maksimal dibutuhkan perangkat tambahan yang disebut tracker matahari. Penelitian ini memiliki kontribusi dalam meningkatkan daya keluaran panel surya dengan mengarahkan panel surya tegak lurus dengan cahaya matahari. Penggunaan penelitian ini sangat bermanfaat dalam penerapan aplikasi tracker multiaxis dari matahari. Dengan mengetahui sudut terbitnya matahari pada setiap pagi hari dan sudut edar sampai dengan terbenam, tracker akan bekerja dengan cepat sehingga energi yang digunakan untuk pergerakan sangat kecil. Sudut referensi yang dihasilkan oleh algoritma pelatihan ANFIS, lebih akurat karena data hasil perhitungan akan dikonfirmasi kembali oleh sensor. Serta sistem ini dapat bekerja secara offline, tanpa terhubung dengan pusat data, sehingga dapat digunakan pada area terpencil atau terisolasi.Kata Kunci : Posisi Sudut Matahari, MPPT, ANFIS, Panel Surya

Processing data in an institution or organization has become an activity or routine for each meeting. In processing data, of course there are various kinds of problems, ranging from missing data, either because of an error in entering data or the result of a system failure. To overcome these problems, in an agency or company must have data backup, so as to create problems that occur in the data, the institution still has data backup. To call, another method of database replication is used. From the test results obtained data on the value of RTA (Round Trip Average) that is the time required for one time sending and receiving data from the replication database is 5426.22 ms and for compilation service diagrams a query attack occurs with a percentage of 29% in the database applications that produce 1774.45 ms results and for service diagrams at a query attack percentage of 29% a single database estimates the server down.
