Sistem Perhitungan DH-Model adalah piranti lunak yang mendapatkan parameter Denavit-Hartenberg untukmemperoleh matriks transformasi lengkap robot. Untuk mendapatkan DH parameter pertama-tama dideklarasikan framereference dan basic reference dari base. Sebelum memperoleh DH parameter dari frame reference, harus dipahami dulutranslasi dari joint pertama ke joint berikutnya.Sistem yang dibuat dibangun dengan Microsoft Visual Basic 6.0, perhitungan matriks dan penggambaran 3dimensi dilakukan dengan Matlab 7.0. Sistem tersebut dapat digunakan untuk merancang robot dengan maksimum 5 jointdan 6 link berdasarkan input user mengenai panjang link, joint pertama, kedua, dan seterusnya. Input data digunakan olehprogram untuk menghitung DH parameter, dan dapat juga menghitung DH matrix untuk masing-masing joint. Setelahmemperoleh DH matrix untuk masing-masing joint, program juga dapat menghitung matriks transformasi total untuk sistemkeseluruhan pada robot untuk memperoleh koordinat pada masing-masing link dan end effector. Setelah memperolehkoordinat, sistem menggunakan matlab untuk menggambar robot dalam 3 dimensi.Program yang dibuat telah dapat mencapai tujuan untuk membantu pengguna dalam menghitung DH parameters, DH matrix,koordinat masing-masing link, end effector dan robot 3 dimensi.

The emerge of the Internet of Things (IoT) data as a commodity to optimize public services such as Fishing Locator has made sensor-cloud an important object. When sensors that are members of multiple IoT gateways can inter-operate at the same time for more than one application, it will reduce cost to deploy IoT infrastructure. However, reliability has also developed as the most important aspect for real-time data collection that should be streamed constantly. Due to uncertainty factors sensors failure is potentially occurred, then an adaptive approach should be addressed into this as to guarantee the flow of streaming data. This paper proposed an adaptive sensor-cloud mechanism to manage the reliability by using a runtime model approach where a transition model and dynamic software product line engineering will take place to weaving the system. Our technique is comparable to other approaches and can be implemented in many types of Cloud-based services.

Pixel puzzle is a logic puzzle which consists of a blank grid with clues on the left of every row and on the top of every column. The objective is to paint blocks in each row and column so their length and sequence corresponds to the clues, and there is at least one empty square between adjacent blocks. There are many possible solutions to paint blocks in each row and column. Solving the puzzle manually gives the possibility to fill cells yield erroneously. Therefore an attempt to solve the puzzle with the aid of computer software is performed.In this paper, ruleâbased techniques and best-first search are utilized to solve the puzzle. According to experiments have been conducted, it can be concluded that rule-based techniques and best-first search are able to solve the Pixel Puzzle. The result also indicates that the larger size of pixel puzzle, the longer average time to solve is needed. Moreover, the average time to solve one cell of pixel puzzle depends on the size itself except for the 10 Ã 10 and 15 Ã 15 pixels.

PSTN phone is static. However, with the development of Android based device, wireless computer network and minimum system, it is possible to make a PSTN phone mobile. To add the mobility behavior in PSTN phone, a research to develop Android based PSTN phone is needed. Android based device will act as a remote control for the PSTN phone and can be used to make and accept a call from distance.This paper elaborates the Android based PSTN phone design. To test the system performance, two parts of testing are performed. First is testing the Android based PSTN phone remote control system and second is testing the digital voice streaming system between Android device and minimum system using UDP protocol over wireless computer network. PSTN phone remote control system is tested for its functionality while digital voice streaming system is tested for its quality by giving a sinusoidal signal to the system and comparing the input signal with output signal using oscilloscope.According to the test, Android based PSTN phone prototype is able to make a connection and disconnection of Android device (as client) with microcontroller (as server), make a connection with auto server discovery system, make a call, receive a call, and use redial and hold functions with 100% success rate in certain condition. However, it is shown that the quality of voice sent from Android phone to Arduino module is poor due to the limited size of buffer in Arduino, but on the other way around the quality of voice sent from Arduino to Android phone is good.

Artificial intelligence has been implemented widely. Many of household products are designed based on artificial intellegence concept. One of them is fuzzy logic system. This paper describes on how a fuzzy logic system can also be implemented in controling the speed of a car in the road. The fuzzy inference system was designed according to Tsukamoto inferencing method and for the defuzzyfication method is used weighted average method. There are three inputs for the system. The are distance between controled car and the car infront of the controled car, distance between controled car and turning point in front of the car and the last is the current speed of the controled car. The output of the system is the next speed of the controled car. For every inputs, three predicates fuzzy are used. Therefore, there are 27 ruler of inference. From the experiment, it can be concluded that the system works well. The performance of the system closely relates with the membership function of each variabel. Keywords: Fuzzy logic, Fuzzy inference, Defuzzyfication
