The energy crisis in the future will be a threat for human life. Many advancements of technology currently focus on creating something that perform better than its predecessor but consuming less power. Light-emitting diode (LED) lighting technology has been introduced as a breakthrough of technology which possesses big advantages rather than other lighting technologies. LED lighting technology is able to produce a high luminous flux with very low power consumption, and also lasts longer than others. By consuming lower power, hence the amount of energy being consumed in order to generate the same amount of light will be reduced, and hence, energy saving will happen. This study discusses the replacement analysis of lighting at classrooms at Engineering Center of Faculty of Engineering Universitas Indonesia. The analysis is in terms of illuminance aspect, power quality performance and cost, and it is done by replacing the existing compact fluorescence lamps (CFL) with three different options of LED lamp exist in the market with competitive price. The study suggests that using LED lamp as a replacement for CFL at classrooms at designated room is more efficient; consuming less energy by 42.86%, and moreover saving the electricity cost as well, from IDR 864,360 annually to IDR 493,920.

In the government agencies, civil servants are required to have competence or ability to finish the work effectively and efficiently. In fact, the decision-making system for determining position and assignment of civil servants' functional works is still performed manually, so it takes a longer time. Moreover, the results are not totally accurate in terms of their competency. Rough set, hereinafter called Single Rough Set, is a common method to solve this problem, but the process may be very complex and still has the unclassified result. In this research, Multi Rough Set and Majority Vote technique are proposed to enhance system performance of single rough set with multi attributes of job competency. It obtains accuracy rate with 5-fold cross-validation that is 83.67% better than a Single Rough Set and it has 0.947 Area Under Curve (AUC) derived from Receiver Operator Characteristic (ROC). Thus, it can be said that the system performance of Multi Rough Set can be considered excellent in classifying job competency for civil servants' functional works.

Femtocell is a small cell of 10–30 meters radius deployed in the existing larger cell (macrocell) forming two-tier femtocell-macrocell cellular network. However, the deployment of femtocell into the existing macrocell cellular network is facing more complex interference problems. This paper focuses on interference management using power control methods for the uplink transmission of such two-tier cellular networks. Types of interferences considered in this paper are co-tier (femtocell-to-femtocell and macrocell-to-macrocell), cross-tier (femtocell-to-macrocell and macrocell-to-femtocell), and total interferences. This paper considers multi-cell scenario of cellular communication network consisting of three macrocell cellular networks in which each macrocell is deployed 10 femtocells. This paper analyzes one of three macrocells on the uplink transmission with the other two macrocells on downlink transmissions. All femtocells are on the same transmission conditions as its co-located macrocells. This paper observes one of ten uplink femtocells on the observed uplink macrocell. Through simulation, this paper firstly analyzes co-tier, cross-tier, and total interferences for the system without power control. The results of Signal to Interference plus Noise Ratio (SINR) in term of its Cumulative Distribution Function (CDF) for the system without power control are used as a baseline system. Then, this paper proposes the use of two power controls namely PC-1 and PC-2 in this paper which both power controls work based on the estimated current SINR. Both power control methods are also to make sure that the transmitting power of the users in the observed base stations (eNB/HeNB in 4G cellular network terminology) will not exceed maximum or minimum of its allowed transmitting power (uplink transmission case). The simulation has been carried out and the SINR results were collected and compared to baseline system. The simulation results show that PC-1 and PC-2 outperform the baseline system in terms of CDF of SINR.

Mortality due to chronic kidney disease (CKD) increases significantly in a recent year. The disease often is diagnosed in an advanced stage. On the other hand, there has been traditional Chinese method or technique to diagnose the presence of the CKD. The diagnosis is carried out by examining pulse palpation at three points namely cun, guan and chi located at the radial artery of the left hand. Records of the pulse pattern of the CKD patients showed irregular characteristics compared with regular pattern obtained from healthy subjects. The aim of this study was to determine the relationship between the frequency spectrum of the irregular pulses related to the stages of the CKD especially from the chi area. Data of the irregular pulse were categorized into 6 stages i.e. 1, 2, 3a, 3b, 4, and 5 of the CKD patients. The data were collected by measuring pressure during systolic periods or when blood vessels were in a relaxed state. In this period, the instrumentation records reflections of the pulse including information about the amplitudes, frequencies, and pulse wave patterns. Observations were focused on the part of the signal between low and high amplitude on pulse patterns (systolic period). The irregular patterns were processed by a Fast Fourier Transform (FFT) technique to find out their special characteristics quantitatively. Results showed that the pattern irregularity was related to the severity of the kidney dysfunction. The FFT processing results showed a number of different special characters in the spectrum. The data were clustered related to the CKD stages. The clustered data of the CKD patients indicates a correlation between the stages and the shifting of the spectrum to lower frequencies which are 0.26 Hz compared to health subject's data 1.11 Hz.

The number of people with diabetes increases every year in the whole world, including Indonesia. Diabetes is a major cause of stroke, heart attack, kidney failure, lower limb amputation and one of the leading causes of death. In order to manage their blood glucose level, diabetics have to test their blood glucose level as often as possible according to certain medical guidance, diet, exercise and consume medicine regularly. Unfortunately, the current blood glucose testing is inconvenient and uncomfortable, even cause pain for diabetic or patient; therefore, a noninvasive blood glucose measurement is highly desirable. Although several research works have already been done in this area, a successful noninvasive method is still in search. In order to contribute in this research area, we study the effect of glucose concentration in solutions with different concentration to the output voltage of a near infrared sensor as a preliminary research to obtain a successful noninvasive blood glucose meter. In this paper, we reported the model of near infrared sensor output voltage as a function of glucose concentration. The main components of the near infrared sensor are a 1450 nm light emitting diode (LED) as light source, and a photodiode that is sensitive to that wavelength as the sensing device. The distance between LED and photodiode is 15mm. The solutions have 50 mg/dl, 100 mg/dl, 200 mg/dl, 300 mg/dl, and 400 mg/dl glucose concentrations. An acrylic cylinder with 40 mm diameter was filled with 5 ml glucose solution for each concentration. The results show that higher glucose concentrations produce lower sensor output voltages. The linear trend line shows good fit with those data. The value of correlation coefficient is −0.99, which indicates strong relationship between the sensor output voltages and glucose concentrations.

Magnetic Levitation or maglev is a method to make an object float in open air without any physical support utilizing force created by electromagnetic repulsion surrounding the object to counter the effect of gravitational force of the object. The object can be levitated if the force created by electromagnetic repulsion equalizes the weight of the object. Lately, this method can be found in many applications such as maglev trains, maglev toys, maglev clock, etc. In this research, we want to show how the Proportional Integral Derivative Controller also known as PID Controller can be used to stabilize magnetically levitated objects. The electromagnetic field is generated by using copper wire coil with 15 millihenry inductance while the object consists of two neodymium permanent magnetic button. The weight and the size of the magnet is 22 grams in mass with 0.5 cm in diameter and 0.5 cm thick. An N-Channel MOSFET Transistor is used to adjust the position of the object with the electromagnetic coil. The PID Controller is used to find the characteristics of the system. The system will stabilize objects floating in many different positions. Arduino Uno microcontroller is used to perform the PID Controller processing with the feedback from the Hall Effect sensor of the system. It is found that with PID parameters Kp = 2.1 Ki = 19.5 and Kd = 0.0025, the objects can be floating with stable condition at the position 1.5 cm from effect hall sensor and with Kp = 0.6, Ki = 3.0 and Kd = 0.0006, the objects can be floating with stable condition at the position 2.0 cm from the Hall Effect sensor. The range in which objects can float with stable condition is between 0.5 cm and 2.5 cm from the Hall Effect sensor of the system.
磁悬浮是一种利用物体周围的电磁斥力产生的力来抵消物体重力的影响，使物体在没有任何物理支撑的情况下漂浮在露天的方法。如果电磁斥力产生的力与物体的重量相等，物体就能悬浮起来。近年来，这种方法在磁浮列车、磁浮玩具、磁浮钟等方面得到了广泛的应用。在本研究中，我们希望展示比例积分导数控制器也称为PID控制器如何用于稳定磁悬浮物体。电磁场是用15毫安电感的铜线线圈产生的，物体由两个钕永磁按钮组成。磁铁的重量和尺寸为22g，直径0.5 cm，厚0.5 cm。n沟道MOSFET晶体管用于用电磁线圈调节物体的位置。PID控制器用于寻找系统的特性。该系统将稳定漂浮在许多不同位置的物体。采用Arduino Uno微控制器，根据系统霍尔效应传感器的反馈对PID控制器进行处理。结果表明，当PID参数Kp = 2.1, Ki = 19.5, Kd = 0.0025时，物体可以在距离霍尔传感器1.5 cm处稳定漂浮;当PID参数Kp = 0.6, Ki = 3.0, Kd = 0.0006时，物体可以在距离霍尔传感器2.0 cm处稳定漂浮。物体在距离系统霍尔效应传感器0.5 cm ~ 2.5 cm范围内稳定漂浮。

This article proposes a practical new method to obtain the moment of inertia of UAV, named ARES. The ARES method simultaneously determined all the elements of UAV's Tensor of Inertia, i.e. the moments and the products of inertia through algebraic solving. The ARES method directly uses the UAV Flight Data to accommodate accuracy issues of modeling such as vehicle's geometrical imperfection; manufacturing defect, any non-symmetrical due component placement, etc. This proposed method was applicable for various purposes of UAV modeling e.g. flight control design, flight dynamics analysis, etc. Conventionally, UAV moments of inertia were estimated by tabulating, CAD-based, or pendulum method. Since these existing methods were constrained by the accuracy and practical issues, we develop the ARES method which using the UAV's flight data to resolve both issues. After undergone appropriate mathematical strategies, the ARES produce a linear construction for algebraic solving technique. The implementation the proposed method in the quadrotor flight data showing that ARES are successfully measured the asymmetrical terms which important for nonlinear controlling, that previously neglected by the conventional methods. Thus, the ARES estimates the UAV Tensor of Inertia in holistic, sophisticated and practical fashion.

This paper will present an implementation of Extreme Learning Machine (ELM) in Prototype of Hand Typist Robot (HTR). HTR is Typist Robot which is designed for quadriplegic people. HTR consists of two robotic arms with three dynamixel AX-12 that mounted on each arm. It is mean that each arm has 3 DOF. To operate HTR, user has to equipped with compass sensor (CMPS10), installed on the part of body that has good function. In this paper ELM is used to map and make decision between the signal which sending by CMPS10 and position of alphabet that will be reached by Robot Arm. The advantage of ELM is superior in training process and easy to implement. Using ELM, the relationship between input and output can be present only using one simple matrix. From the experiment result shown that 73 keys of computer keyboard can be reached by HTR with an error 5%. The error is accumulated errors which is caused by vibration of dynamixel AX-12 when it is moving. To minimize the error the HTR need to reset regularly.
