Information Security Analysis and Solution using LSB Steganography and AES Cryptographic Algorithm
The significance of information security analysis and solutions has been emphasized by earlier
research in several application areas. As a result, information technology has advanced more,
particularly in the areas of security and data secrecy. An essential component of data exchange is
security and confidentiality. A message must first be hidden or encrypted in the picture media to
ensure its security and confidentiality. Our research presents a method for this study, which
involves hiding digital images with color at a depth of 24 bits. Through the development of a
system to improve the security and confidentiality of data in the form of critical messages, this
study seeks to provide senders with solutions. Images are encrypted using the least significant bit
(LSB) steganography technique. The AES algorithm is the cryptographic technique used to lock
or encrypt data. The LSB utilized in this work involves putting ciphertext bits into the image's
color component pixel matrix's diagonals. In this work, the recovery elements of the modified LSB
and AES algorithms were examined to conduct testing

The Role of Bank BRI's BRILink Digital Services to MSME Business Development in Palembang Using the UTAUT Approach
The BRILink application for the BRI Bank Palembang office is a Mini ATM service provided by
Bank BRI for MSME businesses in Palembang. In its implementation, the BRILink application
has never evaluated whether the system created follows user expectations or vice versa. This
evaluation needs to be done to find out, pay attention and determine the next steps necessary for
the developer to develop a better BRILink application according to user needs. This research was
conducted using the UTAUT approach and quantitative methods by distributing questionnaires,
validity testing, reliability testing, descriptive testing, and normality testing. Other methods, such
as multi-collinearity, heteroscedasticity, auto-correlation, partial correlation, coefficient of
determination, simultaneous significance, and individual parameter significance, also apply. The
results showed three (3) variables that proved to be partially clear performance expectations, social
influence, and facility conditions. Only one variable had no effect, namely the business expectation
variable. And all variables simultaneously influence the interest in using the BRILink application
Rainfall Prediction in Palembang City Using the GRU and LSTM Methods
Rainfall is one of the weather elements that are very important for the survival of an area.
Palembang City, as one of the big cities in Indonesia, is heavily influenced by the level of rainfall
that occurs every month. Variations in precipitation can affect various aspects of people's lives,
such as agriculture, industry, tourism, etc. Accurate rainfall predictions can assist in preparing for
multiple activities and making the right decisions. Therefore, it is crucial to research predicting
rainfall in Palembang. It is expected to simplify the prediction process and produce more accurate
results. This research uses the Gated Recurrent Unit (GRU) and Long-Shorted Term Memory
(LSTM) methods to make daily rainfall predictions for the next month using weather element data
for ten (10) years in Palembang, utilizing the deep learning method. The hyperparameter model
tuning experiment was conducted to obtain the best prediction results. From the research results,
it can be concluded that the LSTM model is overall better than the GRU model in predicting daily
rainfall in Palembang City. GRU has RMSE 9.33 and R2 0.54, while the LSTM Model has RMSE
7.45 and R2 0.70
Knowledge and Awareness about Palliative Care and Physiotherapy Management in Palliative Care among Student and Working Physiotherapists in Malaysia: A Comparative Study
Background: Palliative care (PC) needs are increasing in Malaysia. All healthcare providers including physiotherapists have an inescapable role in increasing the quality and development of end-of-life care. The purpose of this study is to compare the level of knowledge and awareness about PC and physiotherapy management in PC between students and working physiotherapists in Malaysia. Methods: A cross-sectional study using a self-administered online questionnaire referenced to the Palliative Care Awareness Assessment Questionnaire published by Sujatha and Jayagowri (2017) was sent to final-year physiotherapy students and working physiotherapists in Malaysia. Results:107 physiotherapists and 107 students were included. Most of the participants from both groups never received training and courses about PC. Participants recognized the benefits of physiotherapy management in PC but showed inadequacy in knowledge and awareness about the skills and techniques. Overall, no significant difference (p>0.05) was shown between the groups. Conclusion: This study revealed the insufficiency of awareness and knowledge about PC from both students and working physiotherapists. It suggests that an emphasis on the development and establishment of PC in Malaysia is clearly needed especially for the working physiotherapist
BENEFITS OF ONLINE ASSESSMENTS IN HIGHER EDUCATION INSTITUTIONS: LESSONS FROM COVID-19 PANDEMIC
The unprecedented wake of COVID-19 pandemic in 2020 forced Higher Education Institutions (HEIs) to move teaching and learning processes to online platforms. Although several studies have investigated aspects of online assessments, the benefits of online assessments have been a scarce area. Thus, the purpose of the current study is to explore the benefits of online assessment in HEIs in the Maldives from the lecturers’ and students’ perspective. This study used mixed methods with triangulation of qualitative and quantitative data. Purposive sampling was used to collect qualitative interview data from full time lecturers (N=30) and students (N=30) from 10 different HEIs and from 11 different disciplines. Data was analyzed using a thematic analysis approach. Simple random sampling was used to collect survey data from 85 lecturers and 312 students. SPSS version 23 was used to analyze the survey data using descriptive statistics. The findings of the study revealed that both lecturers and students found online assessments as an opportunity for self-growth. The data revealed that the lecturers learnt the very basics of technology and pedagogy, a variety of assessment methods and efficient ways of marking test papers and providing feedback to students. Students reported they got more acquainted with ICT basics and research skills. The study showed that online assessments were flexible, convenient and economical. In addition, the psychological issues faced in online assessments were less compared to physical examinations. However, some lecturers highlighted that physical exam answer scripts were easier to mark than online exam answer scripts. In light of the findings, it is recommended to incorporate technology driven pedagogy and assessments in the continuing professional development programs in HEIs so that lecturers are competent and well versed with the contemporary online assessments. In addition, the study implies the room for future programs on online modalities in a more structured manner for the access to higher education across the nation
