AbstrakÃÂ Mouse merupakan salah satu perangkat keras (hardware) sebagai input komputer yang sangatpenting. Mouse umumnya diletakkan di sebelah kanan dari pengguna, digunakan dengan tangan kanan. Hal ini menimbulkan berbagai efek samping dan berbagai kerugian/kesulitan bagi beberapa golongan pengguna. Kesulitan yang pertama terdapat pada pengguna komputer yang menyandang cacat, terutama pada bagian tangannya. Ketidakmampuannya dalam menggenggam dan menggunakan mouse seringkali menjadi halangan dalam menggunakan komputer lebih lanjut. Bahkan tidak jarang mereka menggunakan kakinya di atas meja, atau meletakkan mouse lebih dekat dengan lantai sehingga terjangkau oleh kaki. Hal ini menunjukkan bahwa desain mouse yang diperuntukkan bagi tangan manusia tidak sempurna apabila digunakan dengan kaki. Oleh karena itu, diperlukan mouse yang dirancang khusus untuk dapat digunakan dengan kaki. Meskipun bukan penemuan baru, dan hanya aplikasi lanjutan dari penggunaan mouse, namun rancangan ini dapat memberikan manfaat, khususnya bagi penyandang cacat.ÃÂ Kata Kunci: mouse, komputer, cacat, kakiÃÂ ÃÂ AbstractÃÂ Mouse is one of the most important computer input hardwares. Mouse is generally placed on the right side of the computer user, and used with the right hand. This causes side effects and a variety of disadvantages/ difficulties for some users. The first difficulty is for users with disabilities, especially on their hands. The inability to grasp and use mouse often becomes an obstacle in using the computer. They even put their feet on desk, or put the mouse closer to the floor near the foot. This shows that the mouse which is designed for human hands is certainly not perfect when used with foot. Therefore, specially designed mouse operable with foot is needed. Although it is not a new invention, but only a continued application of a mouse, this design can provide benefits.ÃÂ Keywords: mouse, computer, disability, leg

AbstrakWireless Sensor Networks terdiri atas sejumlah besar titik (nodes) dengan kemampuan untuk melakukan sensing, komputasi, dan komunikasi. Dalam banyak aspek, sensor networks memiliki kesamaan dengan mobile ad hoc networks (MANET), namun memiliki beberapa perbedaan yang penting. Kemiripannya adalah dalam hal topologi, medium komunikasi yang digunakan bersama, dan permasalahan dalam konektivitas. Perbedaannya adalah sensor networks biasanya mencakup mobilitas yang lebih rendah dan sumber daya yang jauh lebih terbatas, oleh karenanya menimbulkan permasalahan skalabilitas. Dalam paper ini, dibahas teknik-teknik pengalamatan untuk sensor networks, trade-off dalam desain skema pengalamatan tertentu, dan perbandingan di antara berbagai teknik.ÃÂ Kata Kunci: wireless sensor networks, nodes, pengalamatan, wireless access media, RETRIÃÂ ÃÂ AbstractWireless Sensor Networks consist of nodes which are able to perform sensing, computation, and communication. In many aspects, sensor networks are similar but also different from the mobile ad hoc networks (MANET). Their similaritiesinclude topology, shared communication medium, and connectivityproblems. Different from the MANET, the sensor networks typically contain lower mobility, much more limited resources, which therefore lead to scalability problems. This paper discusses the addressing techniques for sensor networks, the trade-offs in the design of certainaddressing scheme, and the comparison amongvarious techniques.

AbstractÃÂ Basically, LAN and wireless LAN are both computer networks that are connected to each other, which distinguishes between the two is the media data used. LAN still using cable as a medium for data traffic, while the wireless LAN using a medium wave radio/air. Wireless LAN networks are designed in this paper is intended for an office area which consists of six floors where on each floor there is an access point which is configured with a static route to deliver data packets to their proper destinations via routes that were generated manually. In designing this network simulation authors choose references software from Cisco that is Packet Tracer 5.3. From the simulation results obtained the conclusion that the configuration of the Wireless LAN was able to work well.ÃÂ Keywords: wireless LAN, static route, host, packet tracer

Beberapa penelitian terkait energi terbarukan, seperti energi air, angin, dan bahkan nuklir telah dilakukan. Namun, suara sebagai energi mekanik, ternyata juga memiliki potensi untuk menjadi salah satu alternatif energi. Sebagai konsekuensi dari Hukum Kekekalan Energi, energi suara dapat diubah menjadi energi listrik. Dalam penelitian ini dilakukan pengujian sistem konversi energi suara menjadi energi listrik, dengan memanfaatkan komponen piezoelektrik. Berdasarkan data baseline dari beberapa area jalan dan pabrik, dilakukan pengukuran dengan menggunakan signal generator sebagai sumber suara dan piezoelectric sebagai transducer yang mengkonversi energi suara menjadi energi listrik. Nilai frekuensi yang dihasilkan berada pada kisaran tertentu, dan nilai tertinggi berkisar diantara 760-780 Hz. Semakin dekat sumber suara, resonansi semakin sering terjadi dan tegangan yang dihasilkan Piezoelectric Transducer semakin besar.

In this study, the performance of bipolar optical code division multiple access (OCDMA) with dual electro-optical modulator (EOM) scheme for multi-user scenario was tested and analyzed with OptiSystem version 10. The performance measurement was implemented for free-space optical (FSO) communication and includes the common noises in optical communication. Two different channels were used in the measurement, i.e., additive white Gaussian noise (AWGN) and fading channel. Two extreme weather conditions, strong rain and storm, were considered in the simulation. The performance between three spectral amplitude coding (SAC) codes, i.e., Modified M-Sequence code, Walsh-Hadamard code, and random diagonal (RD) code were measured and compared. The simulation results indicate that Modified M-Sequence code had the highest BER while RD code achieved the lowest BER in the short-range and Walsh-Hadamard code got the lowest BER for the medium-range of FSO, both for AWGN only and AWGN with fading channel. In strong turbulence condition, the performance of all codes become comparable after 500 m of FSO range. Modified M-Sequence suffered the lowest performance degradation while RD code endured the highest performance deterioration in all-weather condition. The results show that Modified M-Sequence can be applied for medium to long-range FSO.

Recently, autonomous robots play an important role in many aspects. Autonomous robots help improve efficiency and productivity, further reduce errors, and risk rates. Employee safety in high-risk work environments is also becoming one of the benefits of autonomous robots. When designing an autonomous robot, two paradigms can be implemented, i.e., planning and reactive paradigm. A distinct feature of the reactive paradigm is that all activities are carried out through behavior. The benefits of the reactive paradigm include can be applied in limited inexpensive hardware resources, low complexity, goal convergence, easy adaptation to changing situations, and a completely unfamiliar environment with unpredictable mobile obstacles. In this paper, the behavior-based reactive system of an autonomous mobile robot is designed to collect stuff objects. Negotiators have been proposed to combine several behaviors into a system that can be implemented in a variety of situations and cases. The results show that a negotiator can be implemented to realize a fully autonomous mobile robot based on the behavior of the reactive system.

The growth in mobile data traffic is forcing network operators to find ways to deliver higher bandwidth, better coverage, and better quality of service (QoS) at lower development costs. One method that can be used to meet this need is the aggregation technique. Aggregation techniques that run on several different technologies are called heterogeneous networks (HetNet). Recently, some advanced technologies have been proposed to aggregate different long-term evolution (LTE) carriers or different radio access technologies (RAT) to generate higher bandwidth. Many efforts have been made to improve the throughput of heterogeneous networks. One of the factors that affects the maximum LTE-WLAN aggregation (LWA) throughput is the Wi-Fi access point (AP) signal strength. Since the power of small cells is very low, the LWA range is not very large, so the LWA range needs to be increased. This paper proposes the solution that can be implemented by using multiple Wi-Fi Aps scheme. From the experiments, it found that LWA with multiple Wi-Fi APs has better signal strength than LWA with a single Wi-Fi AP. LWA with multiple Wi-Fi APs further increase the coverage of the network.
