Abstract

Now days, the home environment is still much less supportive of life for the elderly, most elderly living at home need a companion to help them. Safety, health, happiness and independence will be difficult for them to get even the elderly will be further away from the surrounding environment. Based on population projection 2017 data there are 23.66 million elderly people in Indonesia and predicted in 2020 there are 27.08 million people elderly. Smart homes that are currently widely studied have not focused on elderly; most smart homes only provide a sense of security and convenience for adult residents. And this will be a problem that until now has not solved the improvement of human life through technology to get happiness, care and health especially for the elderly. In many cases of the elderly, it is easier to send them to live in a nursing home and that keeps them separated from their families for the rest of their lives. That's what makes them less happiness. Orange Technology is a collection of technological elements to improve human life by getting happiness, Care and health. This study reviewed the journals of scientific databases such as IEEE explore, ACM digital library and Proquest published from 2002 to 2017. From the search results obtained 54 papers that will answer the scientific questions of this research. The result of this research is a framework of smart house that has Sensor, Monitoring, Wireless, Scalability, Low cost, GPS and ease of installation and maintenance as components of smart house of orange technology for elderly

Abstract

The wind turbine generator used for charging the battery produces an unstable electrical voltage, this is caused by the wind speed on the highway that varies. As a result of the instability of the electrical voltage, the energy storage charging process is not optimal. To deal with these problems, voltage stabilization is carried out using a boost buck converter to maximize the use of electrical energy generated from the wind turbine generator. This study discusses about a prototype voltage stabilizer for battery charging using a boost buck converter circuit. Implemented a comparison of two different techniques, including the application of fuzzy Mamdani logic control with PID using Ziegler-Nichols to minimize the value of settling time, percentage of overshoot, steady state error, and maximum voltage ripple. The results show that application of fuzzy Mamdani logic control is more effective than the application of PID using Ziegler-Nichols. In the study, it was found that the effectiveness of adding a charging circuit protection system and monitoring system did not exist in previous studies.

Abstract

The process of inspection and testing of electrical safety nowadays is commonly done manually. This method has many weaknesses, one of them is the analysis result needs longer time and less accuracy. To overcome this problem, it needs an information system to inspect and to test the effectiveness of electrical safety. The purpose of this research is to design an android-based application which has function to become a tool to make electrical safety inspection and testing much easier. The parameter that will be used is administration documents checking, assessment, measurement, calculation, and testing. The android operation system is used to fasten the work process and get output that meet safety requirements. Black Box method is used to test the app and expected to fulfill the expectation and meet the goal. The result of this paper is that the app shows android-based inspection and testing system for electrical safety can be recommended for faster and accurate report

Abstract

This study focuses on searching for teaching materials in order to obtain relevant teaching material information appropriately for further use as material for recommendation of course material to students using the Cosine Similarity method and calculating weighting using the Simple Additive Weighting (SAW) method. With the SAW method, 3 criteria and weight values are determined for each attribute, followed by a ranking process. So that in the end the search results that are ranked in the order of similarity and most relevant can be displayed and then selected and used as recommendations in the student's e-learning learning system. From the results of the study, the Cosine Similarity and SAW methods have provided a fairly good/effective recommendation with an average precision of 0.7867 and a recall of 0.766 so that this method is appropriate to be placed in campus e-Learning

Abstract

Within this paper, we will discuss about a development process of SpO2 monitoring system that will be used for detecting a patient in the early stage of stroke. This system will measure and compare the SpO2 from both right and left arm at the same time. Stroke patients who experience weakness in the muscles of the one hand can experience different values with hands that do not experience muscle weakness. Stroke patients who are hospitalized with an intravenous infusion in one arm can cause differences in SpO2 values between the right and left fingers. Therefore this measurement method held from that phenomenon. From the monitoring system design, the system should have two sensors to measure the blood saturation, a microcontroller to process the data, and a monitor, buzzer, and micro sd card module to store and display the data. The research shows that the system has been developed and can be used to measure patient’s SpO2 from both hands at the same time, an indicator that will rings when there is an error in the measurement, and a lcd display to show the measurement data. This system also has a microSD card writer to store the measurement data from time to time.

Abstract

To increase education quality on student resources context and learning system, every vocational school has managing self. The Empowerment system as a key component to increase quality in those vacational school. If learning system is owned by vacational school, the learning system will be able to give great contribut on student’s learning activities and student resources be possessed by vacational school will potential to good achievemnt. This study is done with aim groping group-discussion based on indicator communication and humorous to increase their knowledge and skill heterogeneously by using k-medians clustering analysis at Vocational School (SMK) Sore Tulungagung. Communication value and humorous as enhancement study on knowledge and skill in subject digital simulation for student class X expertise competency at motorcycle engineering as base their value. Student class X divided into 2 groups following Group based on k-medians and group based on random than research analysis to get average value k medians communication and humorous to increase study on knowledge and skill before and after learning group-discussion evaluated. The enhancement class value based on  k-medians 4,980 from average before learning 82,542 to be 87,521 after evaluated, while class based random only increase value 0,125 and average before learning 81,250 to be 81,375 after learning evaluated. Based on result of groping group-discussion heterogeneously on indicator communication and humorous to increasing knowledge and skill is grouped by using K-medians clustering method more seen increase.
