Implementasi Sanitasi Data Pada Sistem Operasi Android dengan Metode Gutmann

Data security and privacy are essential for all mobile device users, especially Android. However, deleted data can generally still be recovered using forensic analysis of the storage media hardware with data recovery software. For this reason, you need a data deletion application capable of deleting safely. Many methods are available for safe deletion, such as applying different numbers of passes (overwriting). This research proves that most available methods cannot be deleted entirely and can be recovered, so a data deletion application was created using the most up-to-date method, the Gutmann Method. This method uses 35 number of operands to overwrite the file. Applications are made by analyzing system requirements and implementing them into mobile programming. Then, a comparison test is carried out with other existing applications. The results show that applications created using the Gutmann method are 33% less likely to find file traces than the best comparison application.

Prototype development of a multi-user augmented reality framework for collaborative medical visualization in shared environments

Abstract This study developed and evaluated a prototype for augmented reality (AR) interaction among multiple users sharing a three-dimensional hologram within a shared physical space. A systems requirements analysis was conducted to determine necessary interactions, followed by an iterative implementation plan with testing at each step. The application for the HoloLens 2 (HL2) headset was developed using Unity for 3D design, C# for programming, and Photon for multiplayer capabilities. The prototype was evaluated in a user study utilizing custom and NASA TLX questionnaires, comparing participants' self-reported task success with recorded data to assess the accuracy of selfassessments. The prototype effectively facilitated multi-user interactions within a shared environment, achieving acceptable synchronization for two users. Most participants successfully completed tasks, with TLX scores indicating low cognitive and mechanical load during AR task execution. This study demonstrates AR's viability for displaying and manipulating complex three-dimensional structures within a collaborative medical context among multiple individuals in the same physical space.

Face Recognition-Based Surveillance System in Mining Industry

Access control in mining construction areas is crucial for the operations of mining companies. This access control functions to secure and restrict unauthorized parties from mining activities. Violations of access rights in the mining industry result in significant losses for companies. This access control can also be utilized to record employee attendance, serving as input for the contract work system commonly applied in mining areas. Closed-circuit television (CCTV) is commonly used to monitor activities; however, the current use of CCTV still requires direct human observation, which may result in important events being overlooked. The functionality of these CCTVs can be enhanced to manage access rights and monitor employee attendance to support company operations through face recognition methods. In this study, a system design was carried out through a research approach to determine the technology to be used in the system. The development of a face recognition-based access control system was conducted based on system engineering methodology. This development includes system requirements analysis, the design of a face recognition-based access control system, implementation, and system performance evaluation. The resulting system was tested through simulation processes based on actual field conditions, and the test results showed that the system could recognize faces registered in the dataset and identify subjects not registered in the dataset with an accuracy of 60%, precision of 96%, recall of 58%, and an F-score of 72%. Additionally, the system was able to connect to a database to store face recognition results and then display them on an employee attendance monitoring dashboard. The delay between the face recognition system and actual time ranged from 2-4 seconds and was still tolerable.

Investigation of Conceptual Supply Chain Design Process of Sustainable Shisha Briquette Production System

Abstract Coconut charcoal briquette products have considerable export market potential in foreign countries. One of the product variants of coconut shell briquettes is shisha briquettes. This research aims to investigate the conceptual design of a sustainable supply chain by identifying key stakeholders and understanding the role of each stakeholder and the underlying processes that affect sustainability. The initial step of this research is to conduct an entity system requirements analysis using a use-case diagram to identify key stakeholders. The next step is to identify critical processes using BPMN 2.0 in accordance with established sustainability requirements. Based on the results of the requirements analysis through the entity system and use case diagram, five stakeholders were identified: industry, coconut shell farmers, end consumers, training institutions, and sustainability assessment institutions. According to the results of the business model analysis using BPMN 2.0 with the Indonesian Bioenergy Sustainability Indicator (IBSI), there are three main activities in the raw material procurement process: the selection of coconut shell farmers, facilities owned by farmers, and farmer skills training. Meanwhile, in terms of the production system, there are three main activities, namely production planning, production implementation, and labor training.

Analysis of Altitude and Ambient Temperature Effects on the Reactivity of Oxidation Catalysts in the Presence of H2

Worldwide emission standards are now required to cover engine operation under extreme ambient conditions, which affect the raw emissions and the efficiency of the exhaust aftertreatment systems. These regulations also target new combustion technologies for decarbonization, such as neat hydrogen (H2) combustion or dual-fuel strategies, which involve a challenge to the analysis of exhaust aftertreatment system requirements and performance. This work addresses the impact of high altitude and low ambient temperature conditions on the reactivity of an oxidation catalyst in the presence of H2. A reaction mechanism is proposed to cover the main conversion paths of CO, HC, and H2, including the formation and consumption of high-energy surface reaction intermediates. The mechanism has been implemented into a faster-than-real-time reduced-order model for multi-layer washcoat honeycomb catalytic converters. The model was utilized to investigate the effect of H2 concentration on the reactivity of CO and HC within the catalyst under various operating and ambient conditions. By applying the model and examining the selectivity towards different reaction pathways in the presence of H2, insights into surface intermediates and reactivity across different cross-sections of the monolith were obtained. This analysis discusses the underlying causes of reactivity changes promoted by H2 and its relative importance as a function of driving boundary conditions.
