The use of instant messaging (IM) application is very communal among smartphone users, as it delivers ease in interaction and communication. The speed at which technologies, growth, and expansion of networks infrastructure for high-speed data networks (e.g. wifi, 4G, etc.) are changing and the high number of IM applications are available. IM application usage is significantly escalating, also for doing illegitimate purposes, particularly to organize and coordinate criminal acts. They are practically exploited by the criminality groups involved when they target and interact with the victims, or try to run away from criminal occurrences. By systematically conducting a review to understand and to investigate IM applications topic coming from a number of scientific sources (e.g. manuscripts, metadata, files, etc.), a broader picture and opportunity to regain the valuable evidence in the investigation is academically provided. © 2018 IEEE.

10th Asian Physics Symposium 2023, APS 2023

作者： Nasyidiah, Fungky Iqlima Permana, Sidik Pramuditya, Syeilendra Master Program in Nuclear Science and Engineering Faculty of Mathematics and Natural Sciences Institute Technology of Bandung Ganesa 10th Street Bandung40132 Indonesia Department of Nuclear Science and Engineering Faculty of Mathematics and Natural Sciences Institute Technology of Bandung Ganesa 10th Street Bandung40132 Indonesia

The potential for misuse of nuclear fuel has prompted many to make efforts to prevent a country from acquiring nuclear explosive devices (weapons). Weapon utility equated with nuclear material attractiveness when applied to protection and security. Material attractiveness evaluated using an equation first developed by Masaki Saito, namely ATTR. ESBWR is one of the reactors of the BWR reactor type that is still operating. The purpose of this study is to evaluate Material Attractiveness based on the composition of plutonium in the ESBWR reactor, during reactor operation and after reactor operation. The ATTR concept utilizes the plutonium isotope composition to evaluate the material attractiveness aspect. Parameters such as BCM, Rossi-alpha, and neutron prompt life become additional aspects in evaluating material attractiveness. In the research results, the ATTR value decreased from the beginning of reactor operation until the reactor stopped operating. At the beginning of the reactor operation, it was categorizing as a weapon-grade with an ATTR value of 0.19 and when the reactor stopped operating it was categorizing as an unusable grade with an ATTR value of 0.012. At the time of cooling time up to 1x106 (one million) cooling time, the ATTR value increases by 0.019 which was categorizing as an unusable grade. After a cooling time of 1x106 (one million) years up to 1x107 (ten million) years, the ATTR value was 0.001 which categorized as an exempt level. This states that the increasing burnup value will further reduce the ATTR value. Likewise with the Rossi-Alpha and Bare Critical Mass values. Conversely, it will decrease the value of neutron lifetime. The ATTR value after the reactor operates up to one hundred years of cooling time increases and then decreases significantly after 1x106 (one million) years due to the half-life of plutonium isotopes. Likewise, the Rossi-Alpha and Bare critical mass values. However, it is different with the neutron fast lifetime. © Publis

Information technology enables for new way of commerce, which is a commerce activities through online media (e-commerce). Security becomes an important issue in online-system, because such system is accessible by anyone through the global network -internet. Security in terms of confidentiality, integrity, and availability becomes goals that must be achieved by any system generally, and commerce system especially, because this kind of system contains many sensitive data like customer data and transaction data. SQL Injection is a vulnerability and threat, with the most occurrence in a web based system. In this research we evaluate and analyze source code against SQL injection, and we use regular expression and escape string to prevent the SQL injection. The results of this study are findings of system vulnerability against SQL injection, which are proven by the ability to get data from database, with SQL injection techniques. System vulnerabilities were analyzed, in order to design and implement the solution for it. The solutions then tested, to validate that it has proven effectively fix the vulnerabilities, and can prevent the exploitation by SQL injection. In the end, the conclusion is that initially the system is vulnerable against SQL injection, but then the solution that being implemented has proven effectively fix the issue. © 2018 The Authors.

In terms of global water scarcity, the water footprint is an indicator of the use of water resources that given knowledge about the environmental impact of consuming a product. The sustainable use of water resources nowadays bring challenges related to the production and consumption phase of water intensive related goods such as in the agro-industry. The objective of the study was to assessment the total water footprint from soy sauce production in Grobogan Regency. The total water footprint is equal to the sum of the supply chain water footprint and the operational water footprint. The assessment is based on the production chain diagram of soy sauce production which presenting the relevant process stages from the source to the final product. The result of this research is the total water footprint of soy sauce production is 1.986,35 L/kg with fraction of green water 78,43%, blue water 21,4% and gray water 0,17%. © 2018 The Authors, published by EDP sciences.

The industry developed rapidly since the Industrial Revolution in the 18th century. The side effect of industrial development was a large amount of non-hazardous waste and hazardous waste. All of this waste must be managed properly so that environmental sustainability is maintained and does not cause harm or problems to the community. A review will be conducted from various research journals in various countries and the types of waste also vary, namely plastic, pulp and paper industry waste, and other solid waste. A comparison of solid waste management will be carried on to reduce the generation of waste in the environment. © The Authors, published by EDP sciences, 2020.

Cassava starch industry is one of the leading small-medium enterprises (SMEs) in Pati Regency. Cassava starch industry released waste that reduces the quantity of final product and potentially contamined the environment. This study was conducted to observe the feasibility of good housekeeping implementation to reduce waste and at the same time improve efficiency of production process. Good housekeeping opportunities are consideration by three aspect, technical, economy and environmental. Good housekeeping opportunities involved water conservation and waste reduction. These included reuse of water in washing process, improving workers awareness in drying section and packaging section. Implementation of these opportunities can reduce water consumption, reduce wastewater and solid waste generation also increased quantity of final product. © 2018 The Authors, published by EDP sciences.

Oil and gas exploration and production are two of the activities that potentially cause pollution and environmental damage. The largest waste generated from this activity is produced water. Produced water contains hazardous pollutants of both organic and inorganic materials, so that the produced water of oil and gas production cannot be discharged directly to the environment. Uncontrolled discharge can lead to the environmental damage, killing the life of water and plants. The produced water needs to be handled and fulfill the quality standards before being discharged to the environment. Several studies to reduce the contaminants in the produced water were conducted by researchers. Among them were gravity based separation-flotation, separation technique based on filtration, and biological process treatment. Therefore, some of these methods can be used as an alternative waste handling of produced water. © 2018 The Authors, published by EDP sciences.
