    Using of Thesaurus in Query Expansion on Information Retrieval as Value Creation Strategy through Big Data Analytics

    Authors: Graha Noviana, Agus Rahayu, Ratih Hurriyati, Lili A. D. I. Wibowo, Erwin Yulianto, Rizky Jumansyah

    Abstract

    Research still does not frequently use the concept of value creation through the application of big data analytics. Additionally, the internet serves as a limitless supply of knowledge that comes from different people all over the world and is delivered in a variety of ways, including text documents, photos, audio files, and video. Search engine is a tool used to find different types of information on the internet. The issue that frequently occurs when looking for information online is that the search results for the intended subject are frequently unrelated to the terms entered. In order to increase the relevance of the data obtained from the search results, the goal of this study is to implement the query expansion approach, which involves reformulating the initial query in order to add several phrases utilizing a thesaurus. The waterfall model was used in conjunction with the Software Development Life Cycle (SDLC) in the research. The results showed that the creation of a document search engine based on an information retrieval system was able to enhance data relevance and the standard of document search outcomes in big data analysis. The recall results are higher due to the usage of query expansion, which allowed for the retrieval of more pertinent documents. It is clear that by adopting this technique, the relevancy of the data in the search system can be improved. © School of Engineering, Taylor’s University.

  • Designing an MSMEs Integrated Information System Model through Zakat Management

    Designing an MSMEs Integrated Information System Model through Zakat Management

    Authors: Sri Dewi Anggadini, Deden A. Wahab, Dedi Sulistyo Soegoto, Rio Yunanto, Achmad Rasyad

    Abstract

    The aim of this study is to design a zakat information system model that integrates zakat institutions at the provincial level of West Java, Indonesia, with branches at the district or city level. The purpose of this integration is to impact business continuity for MSMEs. The research method used was descriptive-qualitative, which examined the condition of natural objects and existing phenomena, and collected data using survey methods namely interview, observation, and literature review. The results of this study proposed an integrated zakat information system that are accessible online in mobile and website. The mobile access can make it easier for muzakki in urban areas to make zakat payments using cellphone and immediately receive a receipt for zakat payments. The web access aims to facilitate the reporting of zakat collection by zakat institution administrators. Through this research, integrating mobile-based and web-based features into zakat information system is expected to increase muzakki satisfaction in collecting zakat funds allocated for MSMEs development. This will further impact the development of MSMEs, thereby contributing to the overall economic growth of the region. © School of Engineering, Taylor’s University.

  • Numerical Simulation of Embankment Settlement in Vacuum Preloading Systems

    Numerical Simulation of Embankment Settlement in Vacuum Preloading Systems

    Authors: Mulyawati I. B, Riza M, Dermawan H, Pratiwi V

    DOI: 10.5829/ije.2023.36.04a.18

    Abstract

    In Indonesia, the construction of the road has challenges because the road was built on soft clay soil. The vacuum preloading method was used to improve the shear strength and compressibility properties of soft soil in this project. Moreover, what needs to be a concern for practitioners is the issue of increasing simulation accuracy in predicting soil settlement in a vacuum preloading system. The research objective of this study was to determine changes in soil settlement behavior that occurred from the vacuum preloading system using a numerical simulations Geostudio with the 2D Multi Drain-Plane Strain approach and the settlement result of the simulation will be compare with instrumentation data. In this study the vacuum pressure distribution is modeled using water total head negative pore water pressure and the pressure value used following vacuum gauge data in the field with distribution approach is 100% at the surface of the sand platform, 85% to a depth of 5 m, then 60% to the end of the PVD. Based on the simulations, the conlusion is the vacuum pressure applied along the vertical drainage is not modeled constant, but changes with depth, the value of 60% at the bottom of the vertical drainage is quite representative of the conditions in the field and the settlement from the simulation is quite good at approaching the field observation with a prediction of the settlement due to vacuum preloading of 0.93 m, when compared to the field observation data there is a difference of about 1.6%. © 2023 Materials and Energy Research Center.

  • Analysis of Rail Trailers Selection in Semarang City

    Analysis of Rail Trailers Selection in Semarang City

    Authors: Atty Tri Juniarti, Bayu Indra Setia, Ratu Hedy Syahidah Budiarti, Selfa Septiani Aulia

    Abstract

    This research was conducted in the city of Semarang with the intention of providing an alternative of land public transportation modes other than two-wheeled vehicles (motorbikes) and four wheels vehicles (cars). The development of the transportation mode in question is a train in the city that can reach certain destinations that have not been reached yet, and at low cost. This development direction plan includes accessibility, cohesiveness, capacity, safety, smoothness and speed, and timeliness of travel. Based on this, there are two alternative routes that are considered to be served in this mode. The results showed that the option, which is estimated to provide convenience, can reach many users at a low cost is the second alternative by using a single track along 10,475 km and a double track with a length of range of 5.8 km. © School of Engineering, Taylor’s University.
