Mobile device forensics: extracting and analysing data from an android-based smartphone

The advancement of wireless technology and mobile devices have change our life tremendously. The number of smartphone users increases and majority people rely on it for communication and business related matters. While smartphones are used for positive aspects of our life, it is also used by criminals as medium for their modus operandi. Therefore, there are potential information stored in smartphones that can be used for digital evidence as part of an investigation. However, investigators may face challenges in extracting crucial information and the vital data stored in the smartphone. In this paper, we share on how we studied and experimented several methods on how data in smartphones can be extracted and analysed using the Sleuth Kit Autopsy. The aim of this work is to discover methods of extracting and analysing data from an Android based smartphone. We managed to obtain email, contact, messages, calendar, and images data that can be of used asdigital evidence in an investigation

Determine physical properties of an organic citric acid (processed lime juice) dissolve with water using experimental apparatus

This paper describes experimental studies on the physical properties of processed lime juice to dissolve with water. Lime juice as known as organic citric acid have many advantages in our life especially in food industries, pharmaceutical industries, anticancer and antioxidant and cleaning agent. Physical properties of liquid include pH, viscosity, density, molar mass and surface tension. This Study conducted using common laboratory apparatus such as Pycnometer, the pH device (HI 9811 pH), Viscolite700 etc. The additional organic citric acid by percentage in water was changed the physical properties of liquids. The future strategy of this research is to introduce organic lime juice mixed with water in spray system as cleaning agent, reduce air pollution and reduce water consumption for Commercial Restaurant Equipment

Kesedaran awam terhadap pemeliharaan dan pemuliharaan alam semula jadi: kes Taman Wetland, Putrajaya

Ekoran dari kesedaran tentang impak positif kepada kualiti hidup manusia daripada pemeliharaan dan pemuliharaan alam semula jadi, beberapa kawasan telah dibangunkan sebagai tapak pemeliharaan dan pemuliharaan bagi meningkatkan biodiversiti dan integriti ekosistem flora dan fauna. Namun begitu, aktiviti pemeliharaan dan pemuliharaan lazimnya kurang mendapat perhatian, kerjasama dan komitmen awam dan swasta kerana ianya tidak memberikan imbuhan dan keuntungan material secara langsung dan berlipat ganda. Kajian ini mentaksir kesedaran awam terhadap usaha pemeliharaan dan pemuliharaan alam semula jadi Taman Wetland Putrajaya, sebuah tasik buatan manusia pertama dan terbesar di Malaysia. Kajian ini menggunakan kaedah kuantitatif dan kualitatif melalui 30 borang soal selidik dan dua temubual mendalam informan utama. Secara keseluruhannya, hasil kajian mendapati bahawa masih ramai yang tidak mengetahui fungsi sebenar Taman Wetland kepada pembangunan Putrajaya. Justeru, terdapat beberapa advokasi penambahbaikan infrastruktur, pengurusan dan penglibatan komuniti setempat supaya tanggungjawab ini tidak terserah selamanya kepada institusi kerajaan semata-mata
