Abstract

The process of evaluating student academic achievement results is needed as an effort to monitor student academic development. Grouping students according to the results of academic achievement is needed. One of the uses is as a mapping process for students who can be expected to graduate on time and students whose grades are still low so that assistance is needed. The purpose of this grouping can be used as a student achievement index mapping. The research conducted aims to provide an alternative grouping of academic achievement based on the data mining process using a clustering model. The research method uses the Knowledge Discovery in Database method. The data mining method with Knowledge Discovery in Database consists of selection, pre-processing, transformation, model and evaluation. The datasheet used is a collection of student achievement index data processed from the acquisition of student achievement index in semester 1 to 6. The clustering model is built using the K-Means algorithm. The results of the study resulted in the best grouping is grouping as much as 2, The process of getting the best grouping is done by testing the model with 6 groupings. The best grouping results are done with Davies Bouldin testing. The conclusion of the study with the results of the 2 groups can be given a category, cluster 0 with the name of the good category and cluster 1 with the category not good.

Abstract

Data clustering is one of the methods in data science that is often used in data analysis. This method is used in making groupings from a collection of datasheets. Data clustering is done to find patterns or relationships between data. This research aims to evaluate the accuracy of data clustering using K-Means algorithm on wine datasheet. Wine datasheet has 13 features that describe the chemical characteristics of three types of wine. The clustering process must produce the best clustering evaluation metrics. The evaluation metric is done through comparison between the clustering results of K-Means algorithm with Davies Bouldin and Silhouette. The research steps involved data standardization, selection of the optimal number of clusters, and assessment of clustering accuracy. The research method uses KDD which consists of pre-processing, transformation, model building and model evaluation. Experimental results show that appropriate parameters and cluster initialization can improve clustering evaluation metrics. The clustering results show that the normalized datasheet produces evaluation metrics for Davies Bouldin 2 groups and Silhouette produces 3 groups. Before normalization, Davies Boulidin results in 7 groups and Silhouette results in 2 groups. In conclusion, this study produced different evaluation metrics between normalized and non-normalized datasheets. The selection of the number of groups chosen depends on the context of the data analysis performed and is selected into 3 groups which can be labelled "Superior Variety", the second group "Intermediate Variety" and the third group "Standard Variety".

Abstract

Penelitian ini bertujuan untuk mengetahui kemampuan manajemen sumber daya manusia pada dinas Pariwisata, Pemuda dan Olahraga Kota Bima. Penelitian ini menggunakan metode deskriptif kualitatif. Lokasi penelitian ini berada di Dinas Pariwisata, Pemuda dan Olahraga Kota Bima, lokasi tersebut sangat strategis dalam melihat studi kasus dan permasalahan yang terjadi. Subyek penelitian ini dipilih melalui teknik nonprobability sampling, dengan menggunakan teknik purposive sampling atau teknik penentuan sampel dengan mempertimbangkan aspek tertentu. Teknik pengumpulan data terdiri atas observasi, wawancara, dan dokumentasi. Hasil penelelitian menunjukkan bahwa kegiatan pariwisata sudah menjadi sebuah bentuk dari bidang industri jasa di Kota Bima. Alasan dari pentingnya sumber daya manusia pada pengelolaan pariwisata adalah karena kegiatan pariwisata tidak dapat dilakukan hanya oleh satu orang saja, tetapi harus dilakukan secara bersama-sama oleh sekelompok orang. Dalam hal inilah faktor SDM menjadi faktor yang sangat krusial. Manajemen sumber daya manusia sangat penting terutama agar suatu perusahaan, instansi, atau organisasi mampu menerapkan pengelolaan yang tepat untuk menunjang kualitas. Penempatan posisi pegawai juga harus berdasarkan latar belakang pendidikan dan kualifikasi akademik yang sebaiknya sesuai dengan bidang pekerjaan. Kurangnya kapasitas Sumber Daya Manusia dengan latar belakang pendidikan yang sesuai, dapat diatasi dengan memberikan program pengembangan kompetensi pegawai, seperti pelatihan, workshop, atau beasiswa peningkatan jenjang akademis.

Abstract

In the research of this thesis, the authors conducted a study aimed at determining the relationship between the South China Sea conflict and trade relations between South Korea and China. The types of studies used are descriptive qualitative as well as quantitative. This type of writing is used to provide a clear picture of what is happening in the South China Sea that could affect international trade. While the data collection technique used was literature study, by searching for data relevant to the case study through national and international journals, statistical data, online news, and internet sources. The data obtained are primary data. Data analysis techniques used are qualitative and quantitative analysis techniques. The results of the study obtained by the authors, that is, there are two effects of the South China Sea conflict on trade relations between South Korea and China. First, trade instability in the South China Sea resulting in a decline in trade figures due to escalating conflict. Second, China's dominance in the South China Sea, which as a major player plays an important role, especially controlling the South China Sea and putting pressure on other countries. It often acts as a trigger for conflict even as China benefits from the South China Sea conflict. For South Korea-China trade relations that are more disadvantaged by South Korea, although an indirect influence, there are other dynamics that affect the relationship between the two such as THAAD

Abstract

The BLUD.co.id website was previously developed using the Content Management System (CMS) WordPress, but it encountered security issues in the form of URL redirect attacks that directed users to untrusted sites. This study aims to redesign the information system using the Laravel framework to enhance security and flexibility. The system was developed locally by applying the Model-View-Controller (MVC) architectural pattern and a relational database structure designed independently. The research employed a Research and Development (R&D) approach through the stages of design, implementation, and security testing. Tests were conducted on several scenarios, including SQL Injection, Cross-Site Request Forgery (CSRF), and login bypass. The results indicate that the Laravel-based system was able to reduce the risk of attacks by 80–82% compared to WordPress, while also demonstrating greater stability when handling invalid inputs. These findings highlight that Laravel can provide a significant contribution to delivering a more secure digital information platform for government services, while also opening opportunities for further research to evaluate its application in similar organizational contexts.
