Abstract

Pengembangan listrik tenaga surya yang berbasis pada photovoltaic dari piranti solar cell sebagai salah satu sumber tenaga listrik alternatif yang ramah lingkungan dan ketersediaannya yang melimpah. Namun tegangan yang dikeluarkan dari solar cell masih bersifat fluktuatif (selalu berubah) sesuai dengan perubahan intensitas cahaya yang jatuh pada permukaan sel surya.Pada penelitian ini pancaran sinar matahari masuk menuju ke panel surya dan sensor LDR. Hasil keluaran tegangan akan dirgunakan sebagai input pengisian catu daya baterai berupa tegangan DC. Sensor LDR mendapatkan input dari pancaran sinar matahari dan hasil pembacaan nilai sensor akan dibaca oleh ADC serta diolah oleh mikrokontroler dengan cara memetakan perubahan posisi panel surya terhadap matahari. Dari hasil pemetaan, panel surya akan digerakkan oleh motor DC untuk menuju posisi yang dapat menghasilkan sinar matahari paling maksimal.Dalam menentukan sudut sun tracking terhadap sinar matahari dapat menggunakan minimum sistem, rangkaian sensor LDR, dan modul driver motor yang dihubungkan pada panel surya sehingga panel surya dapat mengikuti arah matahari dan menghasilkan nilai keluaran daya yang lebih maksimal, karena hasil keluaran daya yang didapatkan oleh panel surya saat menggunakan sun tracking mengalami kenaikan sebesar 1,73298 watt atau setara dengan 36.833%.

Abstract

The use of graphs to analyze heart sound signals quite difficult, because the cardiac signals are retrieved and displayed into a graph requires special skills to be able to read and analyze the cardiac signal. Therefore, the authors took the initiative to create an application that can transform the heart sound signal from the time domain into the frequency domain for analysis needs.The process of transformation of heart sound signals using Fast Fourier Transform (FFT).Based on the test results showed the transformation of the heart signal from the time domain to the frequency domain in the experiment with six different cases is particularly evident in the Peak or peak frequency and maximum frequency. Abnormalities of the heart sound signal with voice disorders at low frequencies produces a frequency domain representation of the graph with a small hill in the low frequencies.

Abstract

Stress level measurement using fuzzy logic method is a tool used to measure the level of stress with the parameters of heart rate, body temperature, and blood pressure. Using Arduino Uno R3 as data processor, DS18B20 as the temperature sensor, MPX5050DP as heart rate and blood pressure sensor. The results of the measured parameters are then compared with stress levels table by using fuzzy method as decision makers. Body temperatue measurement using DS18B20 has 99,48 % accuracy rate, while systole blood pressure, diastole blood pressure and heart rate measurements have  91,94 %, 89,59 % and 96,7 % accuracy rate. This system works very well in measuring the level of stress, and the fuzzy system works as expected.

Abstract

Mobile robot is a type of robot that is able to move from one point to another. Mobile robot detects the surrounding objects and process it with the courtesy of webcam. With this particular superiority, mobile robot can facilitate human’s work. One of the human’s work that can be facilitated by mobile robot is any works within security field. Security tools used up until now is a surveillance camera, which has a downside of blind spots. Mobile robot is able to facilitate human’s works with goals of strengthen the security by reducing blind spots.Along with the concerned mobile robot, the author would like to establish a robot that is capable to follow human while walking. The type of mobile robot used in this research is Robotino. The robot follows the human the time when the webcam detected human bodies. The robot’s webcam then, process the image received so that it can detect human bodies using image processing with Haar-like feature method. Then, the robot approaches the human body target that is already detected, using fuzzy logic to control the movement of robot.The human body tracking is capable to detect human body with the most effective detection range of 1-4 meters from the webcam of the robot. The robot is also able to perform tracking towards human bodies with the error rate of 9.6515875 %.

Abstract

Wireless network tecnology has long been discovered. Currently, it is evident that there are significant growth in the number of tools that utilize this technology. One of the impacts of wireless networks is the Ad hoc technology,  which is commonly called the Ad hoc network. Ad hoc is a wireless network that contains a group of nodes that communicate each other. The Ad hoc  networks do not require any infrastructure. The Ad hoc technology has been used in various ways, such as military operations, or personal communication i.e. phone, PDA or laptop. This research will simulate the  Ad hoc protocol routing in large scale network. Performance analysis is done by comparing routing protocol AODV (Ad hoc On-Demand Distance Vector)  and DSR (Dynamic Source Routing) based on delay, PLR(Packet Loss Ratio), PDR(Packet delivery ratio), packet drop, bandwidth utilization and NRL(Normalized routing load) for 10 nodes to 70 nodes.Based on our study it is shown that DSR has better performance in  terms of delay, packet loss dan normalized routing load. On the other hand AODV has better performance in terms of bandwidth utilization for large scale network.
