In 2017, the minister of Indonesia tourism stated that everyone who travels spends his time for culinary about 30-40%. The key point in increasing the tourism income; especially from the culinary sector is about how to inform and promote the wealth of Indonesia culinary to all travellers. The information system of Bengkulu tourism has been developed in the previous study. However, that system has not been able to provide the best culinary recommendations to the travellers. This study focuses on designing and implementing the recommendation system of Bengkulu culinary by using sentiment analysis and simple adaptive weighting (SAW). The recommendation offered is based on the user review and criteria as well. The user review will be classified into positive, negativeand neutral reviews by the sentiment analysis method. If the user needs culinary information based on criteria, the system will provide a recommendation and rank of culinary by using simple adaptive weighting. These criteria used are the average price,opening hours, facilities, distance from a central city, and transportation as well. Sentiment analysis method obtains the accuracy of recomendation classification at 79% while the recommendation rank obtained by the SAW method is 90.83%. These results show that the proposed method has a potential for assisting the travellers to gain the best culinary recommendation, especially in the Bengkulu area.

within remote area worldwide, solar panel is still considered as an alternative with lower efficiency rate and a complex system needing backup source and storage such as battery. PI MPPT controller then used to remarkably improve the efficiency rate of the solar panel by maintaining it on its Maximum Power Point (MPP) reference. However, tackling the complexity of photovoltaic generator for remote area require another solution. This paper provide a simple yet applicable solution by presenting an algorithm to automatically control the photovoltaic generator system for remote area. The algorithm logic is determined by the key parameters from each systems inside, which are solar panel, PI Boost Converter, Battery, and Load. The simulation result proves that the algorithm is able to provide an appropriate result with all condition working properly. Thus, the algorithm is eligible to be applied and to be developed further

Information technology in the health sector has the potential to increase the quality of patient care by improving process efficiency, reducing errors and reducing costs. But this potential cannot be achieved if there is rejection from stakeholders. In this study, we examine the information technology acceptance model in the medical field. We use Moores's model that was developed from Davis's Technology Acceptance Model by adding the variables that determine the success of information technology acceptance. The variables are divided into two categories: information quality consisting of accuracy, content, timeliness, and format. The Enabling factors consisting technical support and self-efficacy. The case study was conducted among medical personnel at a Hospital in East Java. The subject of research is the use of the electronic medical record. Data were obtained through a questionnaire. Then the data is processed with Partial Least Squares algorithm using PLS software. As a result of the sixteen hypotheses proposed there are fourteen hypotheses accepted and the overall model deemed appropriate.

Instant Messaging application is the most widely used application all over the world. Blackberry Messenger is a multiplatform instant messaging with lots of features that can be a magnet for many people to use Blackberry Messenger for commiting digital crimes. In the process of investigating digital crime cases, digital evidences are required. To obtain digital evidence, a set of forensic tools are needed to conduct forensic process on physical evidences. The topic of this research is to describe the forensic process and to compare the current forensic tools used based on acquired digital evidences by using method that refers to mobile device forensic guidelines made by the National Institute of Justice (NIJ). The forensic tools used in this research are Magnet AXIOM, Belkasoft Evidence Center, and MOBILedit Forensic Express. The outcome shows that Magnet AXIOM has the highest capability to obtain digital evidences, Belkasoft Evidence Center has superiority in terms of data text acquisition, and MOBILedit Forensic Express has superiority in physical evidence preserving and cloning.

The efficiency of solar panels is an interesting study now, due to the limitation of material capabilities used in the manufacture of solar panels. The increasing of the received radiation intensity from the sun is a way to improve the performance of solar panels. In this paper will be exposed increased efficiency of solar panels using the method of tracking the sun. The commonly used sunlight tracking is an active tracker, due to significant efficiency improvements compared to passive trackers. The active tracker consists of a single axis and a double axis, both of which use a motor as a driver. This motor is controlled using a microcontroller or a programmable logic controller (PLC). Furthermore, the automatic tracker based on microcontroller or programmable logic controller (PLC) on single axis or double axis which is implemented and can be tested in real time or periodically.

The low learning outcomes of students from year to year in the department of informatics in the course of data structure affect the learning outcomes. The purpose of this research is to know the difference between Student Learning Result between Using Mobile Media Learning application with Conventional Learning. Using a Quasi-Experimental Design. The sampling technique used is Cluster Purposive Sampling. Samples were divided into two groups: experimental groups taught using media mobile learning apps, and control groups taught using conventional learning. The test result data were tested using the Shapiro-Wilk test to know the data normality, F test for data homogeneity, and t-test to know the difference of learning result value with significant level (α = 0.05). Based on the data analysis result, a normality test result with the Shapiro-Wilk test obtained the value of both groups of samples is the normal distribution and the result of the F test is homogeneous. T-test result obtained by probability = 1.830 with α = 0.05 so probability value <α = 0.05 which means H0 is rejected, hence there is the difference of result of student learning between using application of Mobile learning media with conventional learning

This paper presents an adoption of a natural phenomenon as Thunderstorm Algorithm (TA) which is applied to solve a problem of the power production composition under various constraints. This work also introduces artificial salmon tracking algorithm (ASTA) for defining the optimal strategy of the power system on the power consumption. Both algorithms are tested on the IEEE-62 bus system as a selected structure for the mathematical cased model. By considering all parameters, results show that ASTA can be applied to predict the power consumption and TA also has good performances while searching the optimal solution. Moreover, the power production can be presented throughout an economic dispatch problem. Technically, this computation demonstrates the optimal solution with fast convergence and short time consumption. These processes also perform smooth and stable characteristics for the searching completion.

E-Government is an application of government information system technology to support public service system and dissemination of information from government to society that used in every element of government. Batu City Health Office website (http://dinkes.batukota.go.id) is part of Batu City Government e-Government system that was built to support publication of government information to the public. According to observations, there was a decline in visitors from the number 150 visitors in October 2017 to 50 visitors in November 2017. While in December 2017 stable at the number 50 visitors. Based on the anomaly incident, there needs to be an evaluation of e-Government in Batu City Health Office by doing the assessment of website service quality from the user side. This evaluation uses e-Govqual and Heuristic Evaluation methods. Assessment of e-govqual attributes on performance values and interests in the IPA quadrant resulted in the conclusion that there are 24 attributes in A and C quadrants in the IPA quadrant that need to improve attribute quality. Suggestions based on quadrant A and C in the form of recommendation improvement in the form of recommendation mockup based on 10 principles of heuristic evaluation
