Judul: Integrasi Modul Pengelompokan Kode Program C Berdasarkan Struktur pada TOKI Learning Center
Abstrak: Manual detection of source code plagiarism requires a lot of time and effort. Therefore, a system that could help to detect plagiarism of programming assignment is required. The purpose of this research is to build a web application that implements clustering module of C program code based on the structure. The method used to build the system in this research is System Life Cycle. The result of this research is a web application that helps to detect plagiarism of programming assignment in TOKI Learning Center. The application has 3 clustering options, i.e., using clustering method, using the result of test case, and using the combined result of the test case with the clustering method. There are 5 methods of clustering used in the web application, i.e., K-means, bisecting Kmeans, single linkage, average linkage, and complete linkage. To help instructor determine a plagiarism, there are several conditions for consideration provided by the web application, i.e., clustering result, submission time, number of submissions, and the source codes.

Judul: Pendeteksian Penjiplakan Kode Program C dengan Bisecting K-means
Abstrak: Plagiarism of source codes assignments is a widespread problem in academic institutions. Manual plagiarism detection is time and energy consuming. Therefore, a system that can help detecting this plagiarism is needed. The detection can be done by grouping similar source codes based on their structure. This method is used in previous research by using automatic K-means iterations algorithm. That algorithm, although produced decent clusters, had a long execution time. The purpose of this research is to improve the time efficiency and clusters result quality by using bisecting K-means algorithm. The results showed a significant improvement in execution time from 11.68 seconds to 6.64 seconds. Bisecting K-means also produced fewer clusters with slightly better Rand Index than K-means iterations. Furthermore, experiments using 2-gram to 6-gram showed that 4-gram resulted in the best performance

Judul: Duodenal Histopathology of Pediatric Rat (Rattus norvergicus)&#160;Fed with Orange Juice (Citrus sinensis)
Abstrak: This research investigates the impact of orange juice consumption on the histological structure of the duodenum, a critical site for nutrient absorption and digestion. Focusing on pediatric animals, orange juice (with a pH of 3) was administered to post-weaning rats aged 4 weeks to 6 weeks at dosages ranging from 0g/kg BW to 20g/kg BW over two weeks. Duodenal histopathology was assessed, focusing on parameters such as the quantity of crypts of Lieberkuhn, as well as the length, height, width, and depth of villi (measured in µm). Anatomical pathology examination included measurements of the length and width of the duodenum (also in µm), as well as the color mean (OD). The research findings indicate no significant changes in histopathology or anatomy pathology of the duodenum. This suggests that young individuals can adapt to acidic challenges without compromising gastrointestinal health. These findings offer reassurance regarding the short-term consumption of acidic orange juice (with a pH of 3) with minimal risks to intestinal integrity, both during growth and development.
