By taking objects in the Wijaya Kusuma University Surabaya campus environment, the Virtual Tour can introduce the social and physical environment to new students and the general public. This research aims to enable users to feel like they are in the campus environment through the virtual world. The virtual world environment is created in 3 dimensions, which contains an explanation of the object to be targeted; for software design using programming algorithms in the C# language, a finite state machine (FSM) is created in designing the player control system, 3D Blender in creating three-dimensional objects and using Unity 3D in building applications. The research results show an innovation in the form of a 3D virtual tour of Wijaya Kusuma University Surabaya using the Unity 3D platform, which allows users to interact with the campus environment through smooth movements using a virtual joystick. This virtual tour allows users to explore the university in depth by walking around the campus to find important places at Wijaya Kusuma University Surabaya.","PeriodicalId":384527,"journal":{"name":"International Journal of Science, Technology & Management","volume":"55 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140486963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This wealth of data presents an opportunity to implement sophisticated data analytics techniques for predictive maintenance in smart grids. Anomaly detection using machine learning algorithms has emerged as a promising approach to identifying irregular patterns and deviations in sensor data, leading to proactive maintenance strategies. This article explores theapplication of machine learning techniques for anomaly detection in IoT sensor data to enable predictive maintenance in smart grids. We delve into various machine learning algorithms, including Isolation Forest, One-Class SVM, Autoencoders, and Random Forest, assessing their capabilities in identifying anomalies in large-scale data streams. The study also reviews the Performance Evaluation and Model Selection techniques for Anomaly Detection in IoT Sensor Data, possible integration and deployment challenges, and critique of the few selected studies. Explicitly, this scholarly inquiry questions the profound significance of predictive maintenance within the context of Smart Grids. It elucidates distinct categories of anomalies inherent within IoT Sensor Data.Furthermore, the article expounds upon various classes of Machine Learning Algorithms while also clarifying the criteria employed for their selection. Notably, the study probes the potential hindrances that could emerge during the deployment and integration of Machine Learning Techniques specifically aimed at Anomaly Detection in IoT Sensor Data.

Rooted in Islamic principles, Falah encapsulates holistic well-being, prosperity, and the fulfillment of societal needs. The review synthesizes diverse scholarly articles, research papers, and academic contributions to explore the theoretical foundations, policy implications, and practical applications of the Falah-oriented development approach across developing nations. Highlighting the experiences of countries such as Malaysia, Indonesia, Pakistan, Bangladesh, and Saudi Arabia, the study underscores the transformative role of Falah in shaping economic development strategies. From the integration of Falah-based economies to the empowerment of Sharia-compliant economic sectors, each nation exhibits a unique approach to realizing this paradigm. The article emphasizes the significance of aligning with Sharia principles, fostering socio-economic well-being, and contributing to sustainable development goals.

Rice washing water is obtained from water that is washed many times before cooking which is rich in carbohydrate content in the form of starch and glucose and vitamins. Lactic acid bacteria (LAB) require sugar or carbohydrates from rice washing water which is used as food to support metabolic activity and microbial cell proliferation. LAB is also included in a large group of microorganisms that physiologically produce lactic acid as the main metabolic product. LAB are classified as good bacteria so they are widely used as food processing products, especially those related to human digestion. The use of lactic acid bacteria in the agricultural sector is still very minimal, especially as a biodecomposer, even though LAB has the ability to produce cellulase enzymes which are very important in the breakdown of lignin in organic matter.
