A new design of a portable, inexpensive, and easy to assemble horizontal axis wind turbine (HAWT) system for harnessing wind energy that can be reproduced by individuals in the need of electricity has been implemented. The design still follows the Betz’ law theory to define the maximum electrical power that can be extracted from the wind in an open flow area. From our measurement data, the Betz Limit (C) of our design wind turbine is approximately 0.48, meaning it can capture not more than 48% of the incoming kinetic energy of the wind. It was found also that the system can generate a stable at least 5V and 1A of DC voltage and current, respectively. The wind speed is at least ranging from 35 to 55 km/h (∼10 to 15 m/s). We conclude that this HAWT is still able to charge some rechargeable energy recharging devices, such as smart phone or power bank. This HAWT must be put outside to obtain a good amount of wind. But, actually it does not provide a waterproof protection system to make it usable in a rainy season. For further research, a new portable wind turbine can be designed to generate more electric power with waterproof ability system such like using PVC or acrylic which is modeled by this simple prototype.Keywords: Betz Limit, energy recharging devices, harness, maximum power, portable.

Medirossa Hospital is one of the health care centers in the city of Cikarang which in its operations does not only focus on the customer excellent services but also pay attention to the comfort of the environment and the completeness of the health facilities. One factor that determines the convenience of a hospital is the intensity of lighting. From the observations made by the authors of several rooms at Medirossa Cikarang Hospital, namely the casemix room, medical records, VIP treatment, and the hall leading to the second floor has less bright lighting. This observation was carried out by surveying 26 respondents who were hospital employees and visitors. From the observation, 53% of respondents stated that the room was "not bright enough." To find out whether the lighting in the room surveyed is actually less than the Indonesian National Standard (SNI 6197: 2011), it is necessary to measure the intensity of lighting using a measuring instrument, calculating and analyzing of IKE (intensity of energy consumption) values, which can then be continued with lighting improvement if the IKE value is below the applicable lighting standard. Based on the results of calculations and analysis it was found that the value of IKE RS Medirossa Cikarang is 248.603 kWh/m² year. This value indicates that electricity consumption is efficient, but has not fulfilled the applicable standards. To achieve the intensity of lighting in the rooms that have been surveyed, it is necessary to add a lamp that resulted in additional load of 748 Watt. This study aims to provide analysis and suggestion to regarding the intensity of energy consumption of RS Medirossa Cikarang for hospital lighting improvements which in turn can improve the comfort of hospital employees and visitors

Automation or automatic control is the use of various control system for operating any equipment or device such as a remote controlled (toy) car, switching on telephone networks, and other useful applications with minimal or reduced human interventions. This paper proposes a design and implementation of a remote controlled car by wi-fi technology via computer or mobile devices. In completing this research work, wireless software and hardware technologies have been used, such as wireless module of ESP8266 for transceiver (transmitter and receiver), Arduino Uno as microcontroller, an H-bridge L293D IC for motor controller, and two electric DC motors are used to move the automobile. Two objectives of this project are to expand the limitation range of a normal radio frequency car using wi-fi technology and also to create a ubiquitous technology for automobile that operates in daily life with a control system. The test result shows that the controlled car can move in any direction. However, the performance depends on the device signal strength where the maximum testing range is only about 20 meters’ distance from the user’s location.Keywords: automation, wi-fi technology, remote controlled car, Arduino, signal strength.

Bending is one of the causes of signal transmission loss through the electromagnetic wave medium in the optical fiber. There are two types of bendinglossess: microbending and macrobending. Both of them occur when the surface of the optical fiber cable experiences external pressure which causes deformation in the core of the optical fiber. Bending causes the loss of the optical transmission power affected by decreased light intensity, therefore the output ratio becomes degraded to the input one. This kind of condition assumed can be utilized for designing the optical fiber-based sensor by observing the response of the optical fiber against the external disturbances or stimulation.One example is the mechanical force that causes the deformation to the optical fiber. Based on the simulation result through the Matlab programming for macrobending loss, it was obtained that the highest power loss at 1.817×10-4 dB/mm on the 10mm bending radius for the 1650nm wavelength, and the lowest at 2.683×10-8 dB/mm on the 20mm bending radius for the 1250 nm wavelength. Meanwhile for microbending loss, it obtained the largest change of transmission coefficient at 59.070% for 100mm spacer length with applied mechanical force as large as 106 dynes or 10N, and the smallest change at 0.591% for 10mm spacer length with applied mechanical force as large as 105 dynes or 1N. These significant changes of the measured values show that the optical fiber, by simulation, is pretty responsive against the external stimulations, either on the macroscopic scale or the microscopic scale. So that based on its responsiveness, we can assume that optical fiber is most likely possible to be utilized in variousmodern fiber optic sensor for many applied technologiesABSTRAK:Lendutan atau bending merupakan salah satu penyebab kerugian transmisi sinyal melalui medium gelombang elektromagnetik berupa cahaya melalui pada serat optik. Terdapat dua jenis bending, yaitu macrobending dan microbending. Keduanya adalah tipe lendutan yang terjadi ketika permukaan serat optik mendapat tekanan eksternal yang menyebabkan terjadinya deformasi pada inti serat optik. Lendutan mengakibatkan berkurangnya daya transmisi optik dikarenakan berkurangnya intensitas cahaya, sehingga nilai keluarannya menjadi terdegradasi. Kondisi tersebut diasumsikan dapat dimanfaatkan untuk perancangan sensor berbasis serat optik dengan mengamati respon serat optik terhadap gangguan eksternal. Sebagai contoh berupa gaya mekanis yang menyebabkan serat optik terdeformasi. Berdasarkan hasil simulasi melalui Matlab untuk macrobending, diperoleh kerugian daya tertinggi sebesar 1.817 × 10-4 dB/mm pada radius bending 10 mm untuk panjang gelombang 1650 nm, dan terendah sebesar 2.683 × 10-8 dB/mm pada radius bending 20 mm untuk panjang gelombang 1250 nm. Sementara untuk microbending, diperoleh perubahan koefisien transmisi tertinggi sebesar 59.070% untuk panjang penyekat 100 mm dengan gaya mekanis sebesar 106 dyne atau 10 N, dan terendah sebesar 0.591% untuk panjang penyekat 10 mm dengan gaya mekanis sebesar 105 dyne atau 1 N. Perubahan nilai yang sangat signifikan tersebut menunjukkan bahwa serat optik secara simulasi cukup responsif terhadap stimulasi eksternal, baik dalam skala makro maupun mikro. Berdasarkan sifatnya yang cukup responsif, dapat disimpulkan bahwa serat optik sangat mungkin untuk dimanfaatkan dalam perancangan sistem sensor moderen untuk berbagai aplikasi teknologi.

The motivation behind this paper stemmed from the fact that the world consumes the fast-depleting fossil fuel energy. Before the fossil fuel runs out, new technologies to harvest energy from alternative sources are needed. Sunlight is clean, free and abundant. The market for solar thermal and photovoltaic electricity generation is expanding rapidly. Therefore, an analytical review on the types of emitter for solar thermal photovoltaic (STPV) applications utilizing metamaterials and metasurfaces is presented in this research study. STPV is still important in the development of an emitter technology. STPV classifications based on the types of materials, compositions, dimensions, geometries, and long-term temperature stability are considered. The ability to engineer STPV by controlling one or more of the foregoing physical parameters are useful for researchers. Different types of design and simulation tools are considered. The near future plans are to optimize the efficiency of the emitter and investigate how various layers and different combinations of metamaterials affect such an efficiency by employing a simulation tool such as finite-difference time-domain (FDTD, Lumerical).
