Crime is the shadow of civilization. Therefore, the crime will tend to increase in line with the increasingly rapid dynamics of community life. For this reason, it is necessary to take preventive measures or law enforcement intensively and consistently. One of the pieces of evidence that is required to be fulfilled in the law enforcement process is the testimony of a witness who testifies based on what he has heard, seen, and / or experienced himself. This law enforcement effort will not be successful if the community does not optimally participate in giving testimony. The role of witness and victims in supporting law enforcement has not been optimal due to various factors, including: Legislation regulating protection and victims in Indonesia which is still partial and well-known in various regulations and institutional structures are still limited at the central level, not yet at the regional level, including the legal awareness of the community to be witnesses, are still felt to be lacking.Efforts to increase protection and victims that need to be continuously evaluated and refined by relevant legislation, Development of protection and victim institutions (LPSK) up to the district level. For this reason, a strong commitment from the Government is needed to provide protection to witnesses and victims through strengthening the functions and roles of the Witness and Victim Protection Agency by fulfilling aspects of the legal structure and aspects of its legal substance in an effort to encourage changes in the legal culture of the community. Keywords: Optimization, Protection, Victims, Witnesses Abstrak Kejahatan memang pada hakekatnya merupakan bayang-bayang peradaban manusia. Oleh karenanya kejahatan itu akan cenderung mengalami peningkatan sejalan dengan perkembangan dinamika kehidupan masyarakat yang semakin pesat. Untuk itu perlu terus dilakukan upaya pencegahan maupun penegakan hukum secara intensif dan konsisten. Salah satu alat bukti yang dipersyaratkan harus dipenuhi dalam proses penegakan hukum adalah keterangan saksi yakni orang yang memberikan kesaksian berdasarkan apa yang ia dengar, ia lihat, dan/atau ia alami sendiri. Upaya penegakan hukum ini tidak akan berhasil dengan optimal manakala tidak melibatkan partisipasi masyarakat untuk secara aktif memberikan kesaksian. Belum optimalnya peran saksi dan korban dalam mendukung penegakan hukum selama ini disebabkan oleh berbagai faktor diantaranya: Perundang-undangan yang mengatur tentang perlindungan saksi dan korban di Indonesia yang masih bersifat parsial dan tersebar dalam berbagai peraturan serta secara struktural lembaganya masih terbatas di tingkat pusat, belum sepenuhnya sampai kedaerah, termasuk kesadaran hukum masyarakat untuk menjadi saksi masih dirasakan kurang. Upaya mengoptimalkan pelaksanaan perlindungan saksi dan korban perlu terus dilakukan melalui evaluasi dan penyempurnakan Perundang-undangan terkait, Pengembangan LPSK sampai ketingkat kabupaten. Di perlukan adanya komitmen yang kuat dari Pemerintah untuk memberikan perlindungan kepada saksi dan korban melalui pemantapan fungsi dan peran LPSK dengan pemenuhan aspek struktur hukum dan aspek substansi hukumnya dalam upaya mendorong perubahan kultur hukum masyarakat.

This study aims to analyze differences in work behavior through work motivation and employee work stress during the pandemic and during the COVID-19 pandemic. This study uses a quantitative descriptive design by distributing questionnaires to employees in DKI Jakarta. The number of research samples is 100 people using snowball sampling technique. The problems in the study were tested by different tests with the paired sample t-test, MannWhitney (Wilcoxon), and Kruskall-Wallis. The results of this study are that the COVID-19 pandemic weakens work behaviors related to work stress even though work motivation does not. One of the causes of poor work behavior is because employees work from home. Currently, the main cause of increased work stress is because employees are facing increased unemployment since the spread of COVID-19; or female employees whose workloads are increasingly related to the dual roles of employees and teachers at home since school closures. On the other hand, there is no difference in work motivation before the outbreak of COVID-19, because employees have to earn daily income so they can support their families every day and avoid unemployment. As such, managers must comply with laws concerning employment regulations and disclose important information to employees. Managers need to evaluate layoff issues, evaluate and develop continuity plans according to government regulations to improve work and support employees and their families.

Process of determining scores automatically from one or several documents based on text data included in the field of Automated Essay Scoring (AES). Mechanism for scoring answers manually takes a long time to assess students' essay answers, especially for multi-question answers. The implementation of Automated Essay Scoring (AES) is to make correction and scoring easier by application that run on computers. This study applied TF-IDF weighting method and cosine similarity measurement method in multi-question of essay answer document. The test carried out through the preprocessing phase for data extraction, then weighting on each word term. Weighted value is the calculated using cosine similarity to get the degree of similarity. In each question, the point has been given, the cosine similarity value can be calculated with points from each question. This process produces a final score from student answer document which is compared with an expert document. By using the principle of similarity, only the relevant text or character from an expert document will be given weight, to get the similarity value, the number of terms contained in the answer document must match, neither in fewer nor more in number.

The significant increase in the number of users has caused public opinion on the Ruang Guru application to be widely spread through social media, especially Twitter. From 15,000 twitter data taken with the keyword Ruang Guru, a total of 2,358 datasets were obtained through the process of handling duplicates. In this study, sentiment analysis was carried out using the Support Vector Machine (SVM) algorithm which was optimized with Particle Swarm Optimization (PSO) then tested using the 10-Fold Cross Validation method which resulted in the highest accuracy rate of 89.20%, while the Support Vector Machine algorithm (SVM) only produces the highest accuracy rate of 88.56%. There is an increase of 0.64% with Particle Swarm Optimization optimization. Sentiment analysis results are positive, with positive results as much as 1463 data or 62.04% and 895 or 37.96% negative sentiment. From the results of this study, it is expected to be a material consideration for Ruang Guru to improve the quality of the service sector found on social media, especially Twitter.

The spread of information about COVID-19 spreads so fast that the information circulating in the community has not been confirmed. This causes excessive anxiety and fear. There are several approaches to getting things done like design thinking, design sprint, and lean UX. With the right approach, this kind of situation will be resolved. From these problems, in this research, problem-solving will be carried out using a design thinking method. Because design thinking is the best method for developing innovative products. The design thinking process consists of 5 stages: Empathize, Define, Ideate, Prototype, Test. This research has carried out all these stages. The prototyping process uses the Figma mirror application to produce a more real experience for users. Then the prototype was tested on 5 respondents. After the test is carried out, it shows the success data based on predetermined indicators in the form of task 1 success is 80%, task 2 success is 100% successful, task 3 success is 60%, task 4 success is 40%, task 5 success is 100% and task 6 has 60% success. so that the average success of the prototype made is 88%. This means that the prototype developed with the design thinking method is easy for users to use. However, there are still features that have a low yield of 40%. So in the next iteration, it is necessary to improve the interface display that focuses on the call doctor feature based on user feedback.
