<![CDATA[The internet of Things for Smart Home is here to offer convenience in controlling electrical devices or lectronic devices remotely by only giving voice commands that have been integrated with Google Assistant services, now traveling home in uncertain times no longer need to worry about turning on or turn off electrical appliances at home with a smart home. The design of this prototype tool implements lights and fans as electrical devices, in making smart home systems require a microcontroller namely the ESP8266 NodeMCU V3 CH340 module as MQTT Broker protocol, IFTTT as a subscriber, and the publisher Google Assistant using MTTQ (Message Queuing Telemetry Transport) method. MQTT used today is using a free cloud server provided by Adafruit. Based on the results of testing the prototype of the IoT-based smart home control system with the MQTT method using google assistant proved that the number of tests for Relay 1, Relay 2 and Relay 3 is six(6), succeeded 5 and failed 1 then the accuracy of success on Relay 1 testing was 88%. Only by giving the command "Ok Google turn on/off the lamp 1 or turn on/off a fan" to the Google Assistant installed on the Smartphone, lights and fans can be controlled remotely as long as NodeMCU ESP8266 gets an internet network.]]>

<![CDATA[Laboratory assistant in university are the main factors in determining the course of practical in the laboratory. So it needs to be selected to get an assistant with good competence. Assistant selection is done by assessing four aspects namely administration, competence, microteaching, and interview. So far the assessment is still done manually, the criteria value still has the same importance. The calculation method which is also not optimal has an impact on the results and the long time of decision making. So we need a method to overcome these problems. In this study the calculation methods used are Profile Matching and SMART (Simple Multi Attribute Rating Technique). Based on research conducted both methods work by grouping criteria according to their level of importance. There are 12 criteria divided into four aspects, and alternative data of 7 participants were taken from 2019 participant data. The results of the two methods are ranking sequences compared with ranking results in 2019 selection. The results of this study show better profile matching because it has an accuracy value 100% is exactly the same as the results of the previous selection, while SMART is only 42.8%.]]>

<![CDATA[Phishing and identity theft are common threats of online shopping. Phishing is an attempt to steal personal data from legitimate user. In this paper we propose a secure e-payment method using a credit card based on visual cryptography. This method adopts the existing 3D-Secure technology. Visual cryptography is applied in: user-merchant authentication, user-card provider authentication, user-card issuer authorization. It is applied to captcha image generated by merchant during registration using (2, 2) scheme with 2-subpixel expansion, to a text file containing credit card information sent by merchant to the card provider using (2, 2) scheme with pixel replacement, and to quick response code containing one-time-password that is used to authorize the payment transaction using (2, 2) scheme with 4-subpixel expansion. The test results show that out of 100 trials, all of them give 100% true positive. This indicates that the method is able to prevent phishing and identity theft, in sense of authentication, authorization, confidentiality, and integrity are gained. Phishing can be prevented because only legitimate participant who has an image share. Identity theft can be prevented because credit card details are not stored in the merchant’s database. Authorization is more guaranteed because only authenticated user can authorize the payments.]]>

<![CDATA[The failure of most startups in Indonesia is caused by team performance that is not solid and competent. Programmers are an integral profession in a startup team. The development of social media can be used as a strategic tool for recruiting the best programmer candidates in a company. This strategic tool is in the form of an automatic classification system of social media posting from prospective programmers. The classification results are expected to be able to predict the performance patterns of each candidate with a predicate of good or bad performance. The classification method with the best accuracy needs to be chosen in order to get an effective strategic tool so that a comparison of several methods is needed. This study compares classification methods including the Support Vector Machines (SVM) algorithm, Random Forest (RF) and Stochastic Gradient Descent (SGD). The classification results show the percentage of accuracy with k = 10 cross validation for the SVM algorithm reaches 81.3%, RF at 74.4%, and SGD at 80.1% so that the SVM method is chosen as a model of programmer performance classification on social media activities.]]>

<![CDATA[The administration of Indonesian public services has entered the era of Industrial Revolution 4.0, which is a collaborative phase, requiring that every public service implement a service system base on digitization and integrated. The public service that has always been an open discussion is the PATEN Sub-District service. PATEN is a public service system that facilitates community access to get assistance related to population and licensing issues through the Sub-District. Based on PANRB Ministerial Regulation No. 5 of 2018 concerning SPBE Guidelines. SPBE is the framework of the Indonesian Government's Maturity Model, which assesses the level of maturity index in Local Government services. SPBE implementation only stops at the District level and has not touched the Sub-District level, so the SPBE research conducted on public services in the Sub-District. SPBE maturity evaluation has been re-mapped in public services so that not all domains and indicators used. Based on the SPBE mapping results, it produces two domains and four indicators that will use as an assessment of maturity. The data collection method used was a questionnaire. The results showed the evaluation of the maturity of the SPBE in public services in the Sub-District obtained a “Poor” category with a total index value of 1.47. Accordingly, it was necessary to provide recommendations and improvement strategies to increase the value of the SPBE index.]]>

<![CDATA[Identification of object boundaries in a digital image is developing rapidly in line with advances in computer technology for image processing. Edge detection becomes important because humans in recognizing the object of an image will pay attention to the edges contained in the image. Edge detection of an image is done because the edge of the object in the image contains very important information, the information obtained can be either size or shape. The edge detection method used in this study is Sobel operator, Prewitt operator, Laplace operator, Laplacian of Gaussian (LoG) operator and Kirsch operator which are compared and analyzed in the five methods. The results of the comparison show that the clear margins are the Sobel, Prewitt and Kirsch operators, with PSNR calculations that produce values above 30 dB. Laplace and LoG operators only have an average PSNR value below 30 dB. Other quality comparisons use the histogram value and the contrast value with the highest value results in the Laplace and LoG operators with an average histogram value of 110 and a contrast value of 24. The lowest histogram and contrast value are owned by the Sobel and Prewitt operators.]]>
