This paper discusses the performance of gasoline generator set (genset) by using gasoline, LPG, and biogas as the fuel. Combustion engine of the gasoline genset was modified in order to be able to operate using LPG and biogas fuels. A 850 W, 220 V, 50 Hz, single phase generator drive engine has been used in the experiment using 100-W and 200-W bulbs as the electrical loads. Five variables were compared based on the types of fuel and variations of load: fuel consumption (FC), specific fuel consumption (SFC), input energy (thermal energy), output energy (electrical energy), and thermal efficiency. As the results, SFC of the biogas was lower than gasoline and LPG. For 100-W bulb as the load, SFC of the gasoline, LPG, and biogas were 4.5294 kg/kWh, 2 kg/kWh, and 0.68 kg/kWh respectively. While 200-W bulb, SFC of the gasoline, LPG, and biogas were 2.2883 kg/kWh, 1.0742 kg/kWh, and 0.6476 kg/kWh respectively. In addition, the thermal efficiency of biogas was higher than gasoline and LPG. For 100-W bulb as the load, thermal efficiency by using gasoline, LPG, and biogas were 1.6741 %, 3.5884 %, and 10.5710 % respectively. For 200-W bulb, the thermal efficiency by using gasoline, LPG, and biogas were 3.3137 %, 6.6811 %, and 11.0996 % respectively.

Lip reading has wide spread application, e.g. audio-visual Automatic Speech Recognition (AV-ASR), silent speech interface and person identification. Lip segmentation is one of important step in lip reading, because it provides basic information to be processed in subsequent steps. Lip tracking is a process of locating lip to associate lip in consecutive video frames. Chan-Vese model is a region-based segmentation algorithm, which also can be used as tracking method. This algorithm can detect boundary of object which not defined by gradient, while classical active contour can't be applied. This method also can detect object by any initial curve in the image, not necessarily surround the object. This paper investigates about lip segmentation and tracking based on Chan-Vese model, preceded by the color segmentation.

Bali is one of the small islands in Indonesia with total land area of 6,800 square kilometers and with population of around four million people. The island's economy is mainly driven by its tourism industry that leads to annual growth of 6.8%. The life and economy is supported by electric power system with 696 MW generating capacity but at peak time already operating at 679 MW which forces industries to operate their own captive powers. This condition requires swift and effective response from the authority to improve the generating capacity of the local power system so it can continue to support the regional development. Bali has no fossil based resources hence fuel for the power plants need to be externally sourced but with the dwindling capacity of the nation's conventional energy resources together with the prospect of global warming therefore solution has been directed on renewable generation. As tropical island which is in close vicinity of the equator line, Bali has abundant quantity of sun power. The sun insolation index is estimated between 5 to 6 kWh per square meter everyday. And also, photovoltaic system is suited for urgent power demand as it can be built in relatively short time and with advantage of being environmentally friendly. These general facts have led to to the installation of 1 MWp grid connected photovoltaic systems in the village of Kayubihi by the Ministry of Energy and Mineral Sources. The system is currently the largest PV system in Indonesia and connected to the 20 kV distribution network. The report presented on this paper is the review on natural and social characteristics of the location and technical specification of the hardware system. This information are useful in analyzing performance of the photovoltaic system particularly on energy production, reliability of system and components, tariff calculation and investment, as well as developing model for the running of remote PV system based on partnership between local government and university.

Doing a digital image transmission over internet need a secure protection againts ilegall copying. Unfortunately, many current data encryption methods such as DES, RSA, AES, and other only suitable for test data, but not for digital image. In this paper, we propose new secure algorithm for image encryption, which based on RC4 stream cipher algorithm and chaotic logistics map. The proposed algorithm works as follows: (i0 converting the external key into initial value, (ii) using he initial value to generate a key stream using chaotic logistic map function, and (iii) processing a permutation and the result is then XOR-ed with bytes stream of digital image. The experiment results show that the proposed algorithm (i) is able to make the cipher-image can not be visually identified, (ii) can eliminate the statistical correlation between the plain-image and cipher-image, (iii) is very sensitive to small changes of key, and (iv) has no change in image contents (lossless encryption) during encryption and decryption process which is indicated by the hash value (MD5) of plain-image has the same hash value (MD5) wth decrypted image.

Increasing the driving range of an electric vehicle can be achieved by applying regenerative braking. In this paper, how much regenerative braking affects the vehicle will be discussed. The vehicle prototype on this study is Gang Car Electric, a conversion from internal combustion engine car type. The regenerative braking configuration enables the feedback energy active as soon as the throttle pedal being released and emulate engine retarding function of conventional car. With that goal, we still want the vehicle to be able to cruise in a constant speed on the cruise mode. The proposed configuration is included in this paper.

This paper concerns with robust residuals generation such that the designed signatures can be used to isolate actuator faults simultaneously and is not sensitive to exponential autocorrelation stochastic disturbance signal which contaminates one of plant's inputs. The proposed solution of this problem consists of two stages. The first stage is to derive an internal model of stochastic disturbance signal. The internal model is then augmented to the original plant's model so that a new plant's model is obtained. The second stage is to generate a transformation matrix such that each original feature vector of actuator fault is converted into the corresponding designed directional residual with its vector direction as its signature. Based on the designed of signature vectors the modes of residual actuator fault can be decoupled one from others and robust to the stochastic disturbance signal. The transformation matrix is constructed row by row in order each row can block the disturbance signal so that strict robustness can be achieved. To demonstrate the effectiveness of the method a simulation study on a Magnetic -Tape-Drive MIMO system which has multi input and multi output is excuted. The result shows that the method has been successfully implemented.

The study development regarding Axial Flux Permanent Magnet Generator (AFPMG) has been increasingly interesting, since its construction is simple and easy to construct; permanent magnet type NdFeB has high density, available everywhere and relatively low cost; without using brushes and slip ring, thus the maintenance cost can be low, long usage duration, direct drive connection. These will affect in the increasing efficiency and reliability. One of the problems which remain to be the main issue in AFPMG is rotor disc dimension influenced by distance between magnets in rotor disc. This paper discussed magnetic field distribution simulation between permanent magnet NdFeB type N40 with diameter dimension 40 mm and 10 m in height on different pole rotor disc in order to obtain the minimum disc dimension with maximum magnetic flux distribution. Simulation was performed by Finite Element Method Magnetics (FEMM). The simulation result was presented in the form of magnetic field distribution geometry on two permanent magnets inside rotor disc. It showed that the magnetic field strength in the midpoint between different pole single rotor was very low (44 mT) on the distance of 25 mm.

An input current ripple analysis of PWM inverter fed double-stator AC drive system is proposed in this paper. The expression of rms input current ripple of PWM inverter as a function of phase difference between stator windings is derived. It is found that the optimum phase difference that results in minimum input current ripple is 60o. Several experimental results are included to show the validity of the proposed analysis method.

In this paper we propose a content-dependent spatio-temporal watermarking scheme for digital videos. Content dependency is achieved by incorporating the hash of the video sequence into the watermark. The video sequence is treated as a 3-dimensional spatio-temporal signal for the purposes of video hash computation and watermark embedding and detection. Our experiments show that the video hash algorithm has good discriminating power and robustness against various attacks. The watermark is also shown in the experiments to have good robustness against a variety of attacks, in particular when the watermark is copied from one video sequence to another.

A stable light intensity level of a classroom can actually be obtained by integrating automatic lamp brightness controller with automatic blind system. A brightness controller of the lamp, especially incandescent type can be developed by adopting the principle of phase firing angle. It should be implemented in such a way so that the firing angle is set precisely to keep the classroom's light intensity stays in a steady level. Next, the opening and closing process of the blind can also be done using stepper motor which will be controlled automatically by a microcontroller through a hardware driver. This is intended to take the advantage of light contribution from the outside instead of directly switching on or brightening the lamp.
