Since the COVID-19 Pandemic occurred, companies engaged in the retail sector have experienced a decline in the impact of government regulations such as PSBB (Large-Scale Social Restrictions) so that all activities were carried out from home or Work from Home (WFH). to assist companies or agencies with various types of information systems in carrying out their business activities and operations This server is one of the most important in the retail company. The opening of several accesses from the public network (internet) to the local area network (LAN) The security of a LAN network that is accessed from a public network is usually an administrator's problem. Often, the security problems of both the network and the entire application system, as well as the web server, are neglected just to ensure that operational activities run smoothly, and security is only realised after a disaster occurs. Without a good network security and application system, the application of any sophisticated technology will be very dangerous for the company, institution, or organisation itself. So, it takes a security analysis of all activities on the LAN, servers, and other devices to prevent mitigation and to be more aware of server security vulnerabilities. Based on the context of the existing issues, a penetration testing analysis is required. As supporting material, this research also uses guidelines from the CEH (Certified Ethical Hacker) module and the official Acunetix website. The test of this research is aimed at finding the weaknesses of the existing company/institution servers. Among others, quite a lot of weaknesses were found, where each of these weaknesses has a different handling, ports that should be blocked but are opened freely, and access to public IPs that are less important should be closed. The solutions proposed to overcome these problems include: the use of this Acunetix standard can be maintained and continued; testing is much better if carried out more than two times; periodically upgrading SNMP (Simple Network Management Protocol) vulnerable; increasing the level of server security; migration of quality antivirus; and upgrade of expired operating systems.

Masalah kemanan informasi dapat mempengaruhi operasional di suatu perusahaan/organisasi. Resiko yang timbul dapat berakibat proses bisnis tidak optimal, kerugian finansial, berkurangnya kepercayaan pelanggan, menurunnya reputasi dan yang paling buruk adalah hancurnya bisnis perusahaan. Untuk itu diperlukan suatu cara untuk memonitor keamanan informasi di perusahaan ini secara periodik. Metode yang bisa digunakan sebagai best practise  adalah National Institute of Standards and Technology (NIST) Cybersecurity Framework. Framework ini menyediakan mekanisme penilaian yang memungkinkan organisasi/perusahaan menentukan kemampuan cybersecurity saat ini, menetapkan sasaran individual, dan membuat rencana untuk memperbaiki dan memelihara program cybersecurity. Dari penelitian ini didapatkan hasil pengujian untuk fungsi Mengenali (Identify) sebesar 16.67%, Melindungi (Protect) sebesar 32.86%, Mendeteksi (Detect) sebesar 25%, Menanggapi (Respond) sebesar 23.33% dan Memulihkan (Recover) sebesar 58.33%. Namun untuk keseluruhan nilai NIST Security Framework yang didapat hanya 27.55%.

The quality of providing customer service channels is very influential on customer satisfaction. To keep customer satisfaction, it is necessary to have a good interaction from customer service to the customer. In this case, PT Dian Prima Jayaraya is one of the companies that utilize Solo's application product as a medium for customer service. The development of the Solo application makes the application's features more complex and makes it difficult for users to do activities in the application. Customer service has a role in accommodating questions and answering difficulties experienced by users. The number of incoming questions is quite large, so that the existing customer service team cannot answer. Ignored or unanswered questions can lower the level of customer satisfaction. Therefore, we need a system that can help optimize customer service in a Chatbot to minimize unanswered customer questions. A chatbot is a service powered by rules and artificialintelligence, which the user interacts with through a chat interface. The Chatbot will be built on an iOS prototype application and use the NLP (Natural Language Processing) platform, namely Dialogflow. This platform will process and scan every question given by the customer.

Digital information media in this era has very good potential, especially in developing micro-businesses to introduce their products, besides that information media is also needed to provide education and information to socialize, this is very necessary for the government in the district to develop village results and information that can be conveyed clearly to the community. Community service carried out by the Computer Science Study Program of Pakuan University aims to provide training to village office staff and junior and senior high school students in Bantarsari Village to be able to apply Canva as a medium for promoting micro-business and related information media, socialization, disaster prevention, appeals and other notifications in Bantarsari Village
