Herbisida merupakan obat yang efektif membunuh gulma tersebut. Penyemprotan herbisida harus tepat sasaran kepada gulma saja dan tidak mengenai tanaman. Penelitian ini membuat sistem yang dapat mendeteksi gulma secara otomatis diantara tanaman pada lahan pertanian riil. Sistem ini menggunakan gambar lahan pertanian riil yang diambil menggunakan kamera dengan posisi vertikal menghadap ke bawah. Algoritma yang dibuat menggunakan segmentasi berdasarkan warna hijau dalam ruang warna HSV untuk mendeteksi daun, baik gulma maupun tanaman pada beragam pencahayaan. Sebanyak tiga fitur bentuk digunakan untuk membedakan gulma dengan tanaman yang memiliki karakteristik bentuk daun yang berbeda. Fitur bentuk yang digunakan adalah Rectangularity, Edge-to-Center distances function , dan Distance Transform function . Klasifikasi gulma dan tanaman menggunakan metode Jaringan syaraf tiruan (JST) yang dapat dilatih secara offline. Dari 149 tanam...

This system can give many features such as home monitoring, appliance control, and automation system, energy-saving, and home security. A smart home system normally has a centralized architecture. This architecture gives the advantage of being easy to manage. However, the centralized architecture has a fault-tolerance problem. If the center of the system (master station) is down, then the entire system will be failed. A smart home system needs a mechanism to avoid system failure when the master station is down. Furthermore, for the big scale smart home/building system with many devices, the delay time of information transmission and processing can affect the service provision time. To solve the problem, a distributed rule execution mechanism for the smart home system is proposed in this paper. Practical experiments show that the proposed mechanism can avoid the fault-tolerance proble...

Unfortunately, some people are less fortunate due to arms limitations. This limitation can be in incomplete arm organs, such as the absence of the forearm caused by amputation or congenital anomalies. A prosthetic arm is one of the most critical assistive technology they require. In this research, we propose a prosthetic arm system that can be controlled based on the movement of the remaining arm part of the body. Since the prosthetic arm is a wearable device, the designed system will be implemented on an embedded system. This system uses input from the acquisition of electrical activity that occurs in the upper arm muscles. The data were acquired using an Electromyography (EMG) sensor. There are five types of arm movement designed that can be classified based on the amplitude value of the EMG signal. The prosthetic arm performs the motion according to the classification results. The proposed system has an accuracy of 87% in the suitability of the robot’s arm motion.

The system was designed and implemented using network stream protocol which was developed by National Instruments on Lab-VIEW between two devices. The device which acts as the sender was My-RIO board and the receiver device was Personal Computer. The voice data communication system was tested by observing the effect of various buffer sizes on the throughput, latency and CPU usage. The result showed that the larger the buffer size being used, the throughput values were also getting bigger. However, particular buffer size made the throughput became saturated. The change on the buffer size also directly affects CPU usage. It seemed that the buffer size did not affect latency significantly. It showed that the latency was stable with an average of 13 milliseconds on voice data transmission.

The smart wheelchair is an electric wheelchair equipped with camera and line laser to navigate and avoid an obstacle. The camera was used to capture images from the environment to sense the pathway condition. The line laser was used in combination with camera to recognize an obstacle in the pathway based on the shape of line laser image in certain angle. A blob method detection was applied on the line laser image to recognize the pattern of the detected obstacles. The line laser projector and camera were mounted in fixed-certain position to make sure a fixed relation between blobs-gaps and obstacle-to-wheelchair distance. A simple linear regression from 16 obtained data was used to represent this relation as the estimated obstacle distance. As a result, the average error between the estimation and actual distance was 1.25 cm from 7 data testing experiments. The experiments result indicates that the proposed method is able to estimate well the distance between wheelchair and obstacle. Later, the smart wheelchair needs to decide further action whether it should turn left, right or just walk straight when facing certain obstacle to avoid it.

This paper will try to elaborate the term of "Islamic Philosophy" from its etymological meaning as well as the identification that taken from revelationbased worldview of Islam. As the beginning, the definitions of "philosophy" will be derived from number of authoritative scholars. The suitability between Islamic Worldview and the Islamization of Greek Philosophy will answer of the questions about 'the origin of Islamic Philosophy'; including the relation between both the important of revelation (wahy) and semantic interpretation. The discussion is continued widely as well on the history of translation in the time of the Caliph Ma'mun, Abbasid, when the civilization of Islam was in its golden era. Initiated by the caliph himself, this period has introduced many authoritative Muslim scholars in translation of knowledge scripts as well as described a lot of unique facts which rarely mentioned in the general literature such as how does the system of Bayt al-H{ ikmah work, interreligious relation between Scholars, and even the given salary for the Scholars. Lastly, this paper will redefine the historicity and ethnicity of philosopher explaining why does the reason of the term "Islamic Philosophy" become the most appropriate definition. In the deeper analysis, we do not only see 'Islamic Philosophy' as a claim of term but it is also as the 'worldview identification'. Islamic philosophy, has indeed successfully assimilated the sophisticated assimilation of the thought of Greek Philosophy by all of its distinctive and characteristics.
