This study aims to analyze the content planning process and strategy on the TikTok account @Garudasystrain.id managed by PT Garuda Systrain Interindo. Using a qualitative descriptive approach through observation, interviews, literature review, and active participation during six months of Field Work Practice (PKL), this study describes how the company structures its social media workflow to support educational communication in the field of Occupational Safety and Health (K3). The results show that the content planning process is carried out through systematic stages, starting from trend research, idea gathering, content planning sheet preparation, upload scheduling, approval process, and weekly collaboration between team members. These stages ensure that the resulting content is relevant, consistent, and in line with the company's educational objectives. In addition, the content strategy is structured based on the Hierarchy of Effects Model, which includes the stages of awareness, knowledge, liking, preference, conviction, and action, so that the message delivery flow can encourage the audience from recognition to action. The use of clear and targeted Call to Action (CTA) also strengthens interaction and encourages audience participation. Overall, this approach helps PT Garuda Systrain Interindo in using TikTok strategies, improving the company's image, and strengthening the effectiveness of digital communications related to K3.

Rapid technological developments have penetrated various aspects of human life, including data and information security. Amidst the threat of data leaks and misuse, information protection has become crucial. One solution to maintain data confidentiality is to implement cryptography technology. Cryptography is the study of techniques to secure messages so they cannot be read by unauthorized parties. This process is carried out by encoding the original message (plain text) into an unreadable form (cipher text), which can only be understood by those who possess the key to decrypt it. This study used the Caesar Cipher algorithm, a form of classical cryptography. This algorithm uses a substitution method, where each letter in the message is shifted by a certain amount based on a predetermined key. Caesar Cipher is a symmetric algorithm, meaning the key used for encryption is also used for decryption. The security of this algorithm lies in the secrecy of the key, which is known only to the sender and recipient of the message. This method is relatively simple, but still relevant for securing data with low to medium sensitivity levels. This study used WhatsApp messages as the object to be encrypted using the Caesar Cipher algorithm. The results show that encrypted messages become unintelligible without prior decryption. This demonstrates that the Caesar Cipher can protect messages from unauthorized parties. Therefore, implementing this algorithm can be an initial solution for maintaining data confidentiality in digital communications, especially on platforms vulnerable to eavesdropping or unauthorized access. Its primary benefit is maintaining message integrity and confidentiality to prevent misuse.

The method applied in this study is Systematic Literature Review (SLR) and this work examines the pertinent literature between 2020 and 2024. The sources included here were Scopus, Web of Science, Google Scholar while using the following keywords; digital communication and profitability. The findings indicate that firms that engage in anticipatory digital media communication receive higher customer interactions of between 10-30% and continued patronage and sales. Furthermore, AI and big data help organizations tailor their communication strategies, maximize CLV and minimize operation expenditures. However, the study also revealed that digital skills’ dearth and organizational reluctance to embrace digital technology are a thorn for firms, particularly MSMEs, regarding the appropriate execution of digital communication strategies. Based on the findings of this study, the conclusion is that enhanced digital communication can enhance the profitability of the company as long as adequate technological platform and increased digitization of company’s employees are in place. As for the suggestions for future research, they include examining the effects of data privacy legislation on Digital Communications Planning and analyzing how manufacturing and, especially, financial service industries can leverage Digital Technology to create a sustainable competitive advantage.
