<![CDATA[In an underwater wireless sensor network (UWSN), the location of the sensor nodes plays a significant role in the localization process. The location information is obtained by using the known positions of anchor nodes. For underwater environments, instead of using various static anchor nodes, mobile anchor nodes are more efficient and cost-effective to cover the monitoring area. Nevertheless, the utilization of these mobile anchors requires adequate path planning strategy. Mzost of the path planning algorithms do not consider irregular deployment, caused by the effects of water currents. Consequently, this leads towards the inefficient energy consumption by mobile anchors due to unnecessary transmission of beacon messages at unnecessary areas. Therefore, an efficient dynamic mobile path planning (EDMPP) algorithm to tackle the irregular deployment and non-collinear virtual beacon point placement, targeting the underwater environment settings is presented in this paper. In addition, EDMPP controls the redundant beacon message deployment and overlapping, for beacon message distribution in mobile assistant localization. The simulation results show that the performance of the EDMPP is improved by increasing the localization accuracy and decreasing the energy consumption with optimum path length.]]>

<![CDATA[The COVID-19 pandemic is one of the factors that has increased the use of social media. One of the negative impacts of using social media is the occurrence of cybercrime. The possibility of cybercrime can also happen on one of the social media platforms, such as the Signal Messenger application. In the investigation process, law enforcement needs mobile forensic methods and appropriate forensic tools so that the digital evidence found on the perpetrator's smartphone can be accepted by the court. This research aims to get digital evidence from cases of spreading the COVID-19 vaccine hoaxes. The method used in this research is a mobile forensics method based on the Digital Forensic Research Workshop (DFRWS) framework. The DFRWS framework consists of identification, preservation, collection, examination, analysis, and preservation. The results showed that the MOBILedit tool could reveal digital evidence in the form of application information and contact information with a performance value of 22.22%. Meanwhile, Magnet AXIOM cannot reveal digital evidence at all. The research results were obtained following the expected research objectives.]]>

<![CDATA[Zakat merupakan kewajiban bagi setiap muslim yang mampu, Bagi Muzzaki, zakat berfungsi sebagai sarana untuk membersihkan dan mensucikan harta serta dapat menumbuhkan rasa kasih sayang dan kepedulian terhadap kaum miskin. Sedangkan bagi Mustahik, zakat dapat melepaskan mereka dari jerat kemiskinan menuju pada kehidupan yang lebih sejahtera. Data Pusat kajian Strategis Badan Amil Zakat menunjukkan serapan zakat di Indonesia masih rendah. Pada 2016, tercatat zakat masuk Rp 5 triliun. Jumlah ini hanya 1 persen dari potensi zakat di Indonesia sebesar Rp 217 triliun. Dari data tersebut dapat diketahui bahwa potensi zakat di Indonesia belum dapat terserap dengan maksimal. Hal ini disebabkan karena kurangnya pengetahuan masyarakat seputar Lembaga Amil Zakat. Menjalin hubungan yang baik dan menciptakan pelayanan yang berkualitas dengan Muzzaki merupakan cara yang ditempuh untuk menarik minat para Muzzaki untuk mempercayakan zakat kepada Lembaga tersebut. Hal tersebut mendorong peneliti membuat Sistem Informasi dan melakukan perbandingan metode yang digunakan dalam penlitian ini agar mengetahui kepuasan Muzzaki terhadap layanan yang diberikan serta melakukan perbandingan metode yaitu TOPSIS dan ARAS. dari kedua metode yang digunakan dalam peneiltian ini memelikiki tingkat kepuasan yang berbeda, metode TOPSIS mendapatkan nilai 1 pada pilihan jawaban sangat puas di informasi zakat dan bangunan, dan nilai 1 pada pilihan puas untuk informasi zakat sedangkan menggunakan metode ARAS mendapatkan nilai 1 pada pilihan sangat puas di informasi zakat dan bangunan dan nilai 1 untuk pilihan Puas pada informasi zakat. Berdasarkan hal tersebut, perhitungan dari kedua metode yang digunakan dalam penelitian ini mendapatkan hasil yang diharapkankan oleh peneliti dan dapat disimpulkan para Muzzaki puas terhadap layanan yang diberikan oleh pengurus Kantor Layanan Lazismu Gamping serta hal tersebut diharapkan menumbuhkan hubungan baik antara Muzzaki dengan pengurus Kantor layanan Lazismu Gamping sehingga memungkinkan ada Muzzaki baru yang akan menyalurkan zakatnya ke Kantor Layanan Lazismu Gamping.]]>

<![CDATA[Nowadays, the behavior of users in social media arguably represent human behavior in the real world. Training on how to use social media wisely and ethically to young ages is needed to grow the good behavior. Based on a preliminary study, the ages of students in SMK Kesehatan Binatama is considered a terget of such training. 15 years old dominates with 63.6% followed by 16 years old with 29.3% according to age which has the highest penetration rate of social media users reaching 99.16%, namely ages 13-18 years. The activeness of students in social media reaches 99%. The number of hours students use social media where 10.1 % stated between 0-2 hours, 40.4% stated 2-5 hours, 36.4% stated 5-10 hours and 11.1 % more than 10 hours. Knowledge training on social media has been carried out several times but must continue to be carried out along with the development of social media technology and the shift in the age of its users. Training activities with wise and ethical materials using social media have been successfully held with the expected results. Participants' knowledge and insight, namely students can increase with information regarding what can and should not be done when using social media, information about hoaxes and cyberbullying and the ITE Law can be understood properly. The survey results also show an increase in the knowledge provided from the criteria of understanding to criteria of very understanding with an increase from the average score on the pre-test 2.96 with a percentage of 59.2% to the average score on the post-test 3.64 with a percentage of 72.8%.]]>
