Determination of the best path or often called the shortest path finding is a method that has many benefits and can be applied in various cases and fields of science. In previous studies, authors have developed the shortest path finding program using various algorithms, such as held-karp, iterative deepening search, bidirectional depth first search and depth limited search. In this research author implements shortest path finding on information system for determining fire disaster evacuation route using Dijkstra and bidirectional Dijkstra. The program was developed based on web using *** framework. Both algorithms were tested on several datasets and the results will be compared to find out the strengths and weaknesses. Based on the research, the algorithm was successfully developed based on the web using the *** framework and successfully tested on several datasets, it is known that 40% of the test results show that bidirectional Dijkstra is better than Dijkstra, 10% vice versa and 50% get the same results from both algorithms. From this comparison it can be concluded that the bidirectional Dijkstra algorithm is better than Dijkstra. This research succeeded in proving that the bidirectional Dijkstra algorithm can produce a better route than the standard or classic Dijkstra algorithm.

Bitcoin has become a commodity traded by millions of traders from all over the world. This is one of the causes of fluctuating price movements. From the data we got on coinmarketcap, Bitcoin is traded on various cryptocurrency trading exchanges. And at every exchange that has a reputation, of course, has an API service to access historical data about the price movements of all the crypto commodities they have traded from the start. By using the PHP programming language and implementation of the CURL function for JSON readings, we can pull Bitcoin movement data in real time. In this paper, Bitcoin is specifically observed because it is the forerunner and the main cryptocurrency commodity traded and is a determinant of Alternative coin price movements in general. In this paper Bitcoin price monitoring is carried out at 30 reputable exchange places through API access provided by each exchange place. Furthermore, conclusions are drawn about the various variants of how to access the API from the 30 bitcoin exchange places. The program code that is displayed directly in this paper can then be used as an initial reference if you want to develop a Cryptocurrency price movement monitoring application for Bitcoin. At the end of the paper, an example of the application of Bitcoin price monitoring will be presented using a web-based application containing charts and supporting indicators as well as a telegram bot to display price depth charts.

作者： Adelin Febria Sri Handayani Information Systems Study Program STMIK PalComTech Palembang

The existence of batik as one of Indonesia's cultural heritages lately has been echoed to become a fashion trend for young and even foreign generations. The preservation of batik needs to be done by introducing it as widely as possible. It is also commensurate with UNESCO's decision to recognize that batik is a world cultural heritage that was born from Indonesia. In addition, the number of studies and free articles that discuss about the nusantara batik in various media also contributed to the reason for the development of *** as a batik catalog of the nusantara. *** will gather information about batik in the form of an online catalog. *** development uses extreme programming. While modeling the process using Unified Modeling Language (UML). It also produced an interface design for admins and visitors.

Journal of Physics: Conference Series 2020年第1期1500卷

作者： Mardiana Eka Hartati Information Systems Study Program STMIK PalComTech Palembang

SISKEUDES is a village finance application developed in 2015 by the Financial and Development Supervisory Agency. The application of the new SISKEUDES application for several years has been implemented in South Sumatera and it can be determined that there is no measurement of user satisfaction. The purpose of this study was to measure the level of user satisfaction using the Green Pearson model which consists of variable ease of use, customization, download delay and content. The results of this study on the Customization variable had the highest score of 79%, which means that the SISKEUDES application is in line with the expectations of users in the display of attractive applications and the information presented is easily understood, especially by village finance operators. Whereas the User Satisfaction variable had the lowest value of 37%, which means that for now the SISKEUDES application cannot be accessed with media gadgets because this application can only be accessed by a computer or laptop with application that has been installed.

The road functions as an infrastructure of traffic movement and its performance can be assessed. It has mattered in performance, including durability, economic value, planned life, comfort, and flexibility. The roads can be damaged and require repairs to maintain performance. Handling road damage in Indonesia is still found to be a mismatch between planning and implementation. This research was conducted to assist decision-makers in determining the type of road construction in accordance with technical and non-technical factors. Factors used to assess eligibility in the selection of road improvements is the type of concrete construction or asphalt construction. This study intends to develop a decision support system to determine the type of road construction. The model was developed using Analytical Hierarchy Process method. The factors used in the model are the availability of resources, road surface comfort, weather resistance, ground movement, traffic conditions, and maintenance period. The results showing the technical factors have the highest weight resistance to weather (0.491), and non-technical factors are the availability of resources (0.667).

An e-Commerce company has been using an Enterprise Resource Planning (ERP) system for several years, but is still constrained in its implementation, this is reflected in the number of issue/change request tickets submitted by users who have not been able to reach ideal conditions. To overcome this problem, we need an appropriate reference model, the ERP system user acceptance model in companies. The study conducted factors that influence the level of acceptance of SAP ERP users in the XYZ group to then determine a model that is able to explain practically the level of ERP system user acceptance, which in turn can produce concrete proposals to increase ERP system user acceptance. Research is quantitative descriptive using factor analysis and regression analysis methods. The research method uses a questionnaire with a total of 107 valid respondents coming from 8 company names under the XYZ group in 6 Southeast Asian countries. The conclusion of the study is that there are 24 indicators and 4 factors that influence user acceptance of the SAP ERP system. These four factors are the low contribution of the ERP system, the quality of ERP systems and data, the development of ERP systems, and also the low quality of ERP system supporters. It is hoped that by optimizing the value of the 4 factors, the XYZ group can increase user acceptance of the SAP ERP system so that the system can provide benefits expected by the company to be competitive advantage.

Most tourists have limited time and schedule when they are visiting a particular tourism area. One of the main issues faced by those tourists is that they can not make simple queries to search engines about, for example, which sites or places to visit optimally if we only have one day or two-day visit? Search engines are better and better in replying users' queries with relevant answers. However, search engines are not always able to respond queries suited to users' characteristics such as their styles, personalities, knowledge backgrounds, etc. Also, search engines are not as flexible as chatbots in enabling dialogical-communication-queries. This case study aims to respond aformentioned issue by applying hierarchical cluster analysis on a set of tourism sites around Malang city, Malang regency, and Batu city based on AGNES (Agglomerative Nesting) algorithm. The result, then, is fed into chatbot's knowledge base. This chatbot will assist tourists to get information on which possible sites they have to visit optimally if they are under limited vacancy-Time constraints. © 2018 IEEE.
