Analisis Intensitas Konsumsi Energi RS Medirossa Cikarang
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

A Novel Detection Strategy for Kidnapped Robot Problem in Monte Carlo Localization Using Corridor-Type Map
This paper proposed a novel method to detect the kidnapped robot problem event in Monte Carlo Localizationin corridor-like map. The proposed method is aimed towards overcoming two commmon drawbacks from existing methods of detection, namely the inability to stay accurate across wide array of particles’ convergence level, and a high dependency on the success of recovery process. This objective is achived by combining the difference in particle’s weight, maximum current weight, and difference in particles’ standard deviation. The addition of these two parameters makes the proposed method to be superior to pure maximum current weight parameter for kidnapping detection. A series of simulation tests using corridor-like map are executed to test the claim. These simulations show that the proposed method outperforms the maximum current weight parameter in terms of accuracy, ability to detect kidnapping during early stage of localization, and independency towards the success of the re-localization process.
Designing and Prototyping Record System for Machine Usage Time
Machine cost is one of the components of production cost. Accurate record of machine usage time is thus crucial to obtain accurate production cost calculation. Besides, machine usage time can be used as parameter to assess the performance of the machine operator. Furthermore, the data can be used as input to the machine’s maintenance and reparation plan. The author is motivated by the current problems found at Akademi Teknik Mesin Industri (ATMI) Cikarang, where it is still possible to use one machine simultaneously by more than one operator. This causes inaccuracy in calculation of machine usage time and production cost. In this paper, the author proposed a design of device to record detailed data of shop drawing and machine usage time. By the use of this device, a certain machine will be activated and deactivated by using RFID technology, with the whole system controlled by Arduino Mega 2560 microcontroller. Furthermore, the shop drawing and machine usage time will be able to be accessed through a Windows-based interface application, implemented by using Visual Studio. A database is also made available by using Microsoft Access. The use of the proposed device makes possible of accurate measurement of production time efficiency and machine operator performance. Through this improved accuracy, further analysis can be made in order to achieve production improvements in planning, process, and maintenance.

Perancangan Detektor Kebocoran Gas LPG Berbasis Arduino yang Terhubung dengan Smartphone
LPG (Liquefied Petroleum Gas) has become the fuel for cooking for most households in Indonesia. The use of LPG for cooking requires high level of caution, due to the danger that may arise from gas leakage. If the molecules of flammable LPG gas are present in the air at a certain concentration and there is a triggerring factor in the form of flame or sparks, explosion and fire may occur. To prevent disasters caused by a LPG gas leakage, the author proposed an Arduino-based LPG gas leak detector (GLD). The GLD is equipped with a MQ-2 gas sensor, capable of measuring the LPG concentration in air in units of parts per million (ppm). Based on the measurement result, the GLD provides an early warning of LPG leakage through 3 condition levels: Normal, Alert, and Danger. Each condition level is characterized by the activation of LED indicators, a miniature air circulation fan , and a buzzer. Alert warning is released when the sensor reads more than 400 ppm (2.05% of LPG Lower Explosive Level). Danger warning is given at 800 ppm (4.10% of LPG Lower Explosive Level) or higher reading. An HC-06 Bluetooth module creates a wireless connection between the GLD and a smartphone. Through an application created on Blynk platform, the smartphone can monitor the LPG concentration at a distance of 10 m from the GLD. The GLD is tested and succeeded to detect gases coming from an LPG cylinder and from a gas lighter. The GLD also runs perfectly for the designed early warning scheme.

Portable Wind Turbine for Energy Recharging Device Applications
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, Â portable.
