Abstract

The problem that occurs in the application of K-Nearest Neighbors as a classification algorithm is the frequent occurrence of overfitting in data processing. This can be overcome by using cross-validation techniques in evaluating the algorithm model and minimizing overfitting. Then the performance of diabetes prediction accuracy is unknown using the K-Nearest Neighbors algorithm with cross-validation technique. The data used comes from the National Institute of Digestive and Kidney Diabetes in 2021. The case study in this study is to find out the initial screening for diabetes is supported by the results of algorithm accuracy and real time application of streamlit-based users. The purpose of this study was to optimize the accuracy results with a cross validation technique supported by the k-nearest neighbors algorithm in the study of diabetes data. The method used is the k-nearest neighbors algorithm which is supported by cross validation technique for optimal accuracy results. Then the application of a streamlit-based interactive web application for testing the accuracy results used by the user to see the probability that the user has diabetes. The results showed that the optimization of the Cross Validation technique supported by the KNearest Neighbors algorithm model worked well. The results of the confusion matrix using the cross validation technique are more accurate in terms of the advantages of using the cross-validation technique itself. So that the classification report which has a value of 95% is more accurate than the accuracy which is worth 92% because of the use of cross-validation techniques that can minimize overfitting in addition to considerations of the accuracy value and the implementation of streamlit-based interactive web applications for user testing is going well.

Abstract

e-commerce is a quickly expanding industry in the more sophisticated digital age, particularly in the market for health products. More individuals are doing so because purchasing health items online is so convenient. However, as technology develops, so does the possibility of cybercrime, which puts online shoppers in danger. Legal protection is thus crucial to safeguarding customers throughout their online transactions. Finding out and discussing the legal protections afforded to online shoppers of health products—lessons learned from cybercrime—is the goal of this study. Normative legal research techniques (normative juridical) and empirical legal research methods (empirical juridical) are the research approaches employed to address the issues in this study. Primary and secondary data are the two categories of data employed in this descriptive-analytical study. Based on the study findings, it can be said that customers may trade online confidently and without fear of becoming victims of cybercrime if they have legal protection. In order to safeguard customers and maintain the safety and reliability of the health product market, governments and e-commerce companies must collaborate. As a result, online shoppers may complete their purchases without concern about fraud or cybercrime, giving them peace of mind.

This research method approach is quantitative research with a correlation analysis design. The instruments used consist of the use of social media, digital marketing and pedagogical knowledge. The data collection technique uses an instrument in the form of a questionnaire and is analyzed using descriptive and inferential statistical analysis. The research results show that there is a very significant positive influence between the variable use of social media for digital marketing learning on pedagogical competence with a low strength of relationship (r = 0,584 p<0.01). The existence of a positive relationship means that the higher the use of social media for digital marketing learning, the higher the pedagogical competence related to information technology. The theories used in this research are not yet extensive, it would be good in the future that scientific developments will enable the emergence of new theories that can explain the increase in pedagogical knowledge in the field of information technology, which can then provide different results in other research.

Abstract

SMP Negeri 3 Watukumpul is a junior high school located in Bongas Village, Watukumpul District, Pemalang Regency, Central Java. This school has implemented website-based technology as a medium for conveying information, but the website is no longer usable. The data obtained from the interview results indicate the need for an academic information system website as a medium for disseminating information and managing academic data digitally. Based on the existing problems, researchers will re-create a website-based Academic Information System for SMP Negeri 3 Watukumpul as a medium for delivering information and managing academic data. This research uses the Extreme Programming method, which is one of the development methodologies of Agile Software Development Methodologies. The Extreme Programming method has several stages: Planning, Design, Coding, and Testing. The system uses black box testing on student, admin, and teacher accounts. Blackbox testing on student accounts includes login, register, profile, news, wall magazine, course material, grades, contacts, and logout menus. Blackbox testing on teacher accounts consists of login menus, course materials, grades, and grade page details. Black box testing on admin accounts consists of login menus, school profiles, teachers and employees, news, wall magazines, extracurriculars, and lesson schedules. In testing this system, researchers use black box testing to test its functionality. The black box test from the student's account got a result of 100%, the black box test result from the teacher's account got 100%, and the black box test from the admin account was 98.57%. Thus, the average black box test result from the three users was 99.52%. With the existence of this school website, it is hoped that information dissemination activities and academic data management activities will become more effective and efficient.

Abstract

Agribusiness utilizes inorganic waste that can be recycled to produce selling points such as basket bags from plastic waste and dolls from cloth waste. There is a superior product in this business unit, namely processed Jenitri seeds which are processed into handicrafts. Jenitri seeds are not only used as an ornamental tool. In certain beliefs, the work of Jenitri seeds is used as a worship tool and a medical device. Therefore, Jenitri seeds have a fairly high selling value compared to other handicrafts because of their various functions. Adiluhur Tourism Village is a village that is currently under development as a tourist spot with the name Kebumen English Tourism Village (KWIK) and is located in Adiluhur Village, Kec. Adimulyo, Kab. Kebumen. There are 3 business units that are superior and are still in the development stage, namely business units in the fields of tourism (agro-tourism), agriculture (agriculture), and handicrafts (agribusiness). Currently, the primary superior unit in Adiluhur Tourism Village is a business unit in the tourism sector. Agrotourism is managed by CV in collaboration with BUMDes (Village Owned Enterprise) Mulia Jaya. The tour featured in this unit is an introduction to several types of captive animals (various types of snakes, monitor lizards, sea urchins, iguanas, mongooses, Australian geckos, crocodiles, alligator fish, and many more) as well as a museum containing ancient agricultural tools (bronze spoon, harrows, sickles, hoes, nails, antique lamps, and many more). The potential that is being developed in this unit is outbound with the target visitor being Elementary Schools. Not only that, the agro-tourism manager plans to work with the BKSDA (Natural Resources Conservation Center) in caring for the animals in the unit.

Abstract

MTS Attaqwa 04 merupakan institusi pendidikan yang berfokus memberikan pendidikan yang berkualitas dalam bidang akademik. Oleh karena itu diperlukan pemantauan dan analisis secara berkelanjutan terhadap hasil akademik siswa. Akan tetapi, dalam pengumpulan data masih dilakukan secara manual dengan menggunakan aplikasi microsoft excel yang hanya bisa diakses oleh 1 admin dan pengerjaannya memerlukan waktu yang lama. Sebagai solusi, perancangan sistem berbasis web dengan Penerapan algoritma K-Means Clustering ini dapat melakukan proses pengumpulan data untuk mengetahui kemampuan akademik siswa, menetapkan bobot dan kriteria dalam menentukan hasil akademik siswa dan mengetahui hasil pengukuran pengujian fungsionalitas yang menunjukkan kinerja efektif untuk penggunanya. Penelitian ini, menjadi dasar untuk penelitian lebih lanjut dalam melakukan pengembangan sistem pendukung berbasis web baik dengan kerjasama ataupun perbandingan sistem lainnya.
