Abstract

In higher education, the completion of a thesis within a 1 -year timeframe is a prerequisite for graduation. The selection of a thesistopic is influenced by personal interest, the expertiseof the thesis supervisor, and data availability. This research is designed to analyzethe thesis topics of Economics Faculty students at Garut University using the Latent Dirichlet Allocation (LDA) Modeling method. Utilizing quantitative and qualitative approaches, this research applies the concept of big data with techniques such as Data Crawling, Data Preprocessing, and Text Mining. The research successfully conducted topic modeling using the LDA method. The analysis showed that topic modeling with the LDA algorithm resulted in seven common thesis topics used in the students' thesis titles. With this, theresearch contributes to the understanding and efficacy in the determination of students' thesis topics. It is hoped that the results of this research can be utilized to assist in the efficient completion of theses.

Abstract

SatuSehat is a contact tracing application that replaces the PeduliLindungi application initiated by the Government of Indonesia with the aim of tracking the Covid -19 Virus. The success of the application can be known by analyzing sentiment reviews. In addition to the high number of reviews, there are also other things that need to be highlighted, namely the pattern of reviews that are not in accordance with refined spelling and diverse topics, so that identifying a topic from a collection of reviews is very difficult and takes a lot of time if done manually by humans. This research describes sentiment analysis and topic modeling on SatuSehat app user reviews. By applying Support Vector Machine (SVM) method for sentiment analysis and Latent Dirichlet Allocation (LDA) for topic modeling, this study reveals the views and trends expressed by users. The analyzed review data from Google Play Store includes 171,428 positive reviews and 131,246 negative reviews. The sentiment analysis results indicated the dominance of positive responses. LDA modeling resulted in 8 identified topics, from health concerns to app appreciation. However, negative topics included vaccination challenges, access issues, and app functionality. This research provides insight into users' perceptions of the SatuSehat app, providing a basis for further development and improvement of the app.

Abstract

In the current era, technological advancements in Indonesia have created extensive resources for information and communication for the community also equal with basic human needs such as clothing and food. SMKN 2 GARUT is a favorite school in Garut city, with a focus on academic and non-academic achievements. Despite the school utilizing technology such as a website, the alumni data management system, including tracer studies, is still conducted manually. This research for develop a website-based tracer study information system for SMKN 2 GARUT. Currently, alumni data is collected through the filling of biodata forms, which are then submitted to the Counseling guidance for consolidation and management. After verification, the data is sent to Headmaster. However, the system still relies on manual processes with the use of poorly managed gform links. This leads to delays in information delivery, ease of data duplication, and human error risks. In this research, the researcher employs the prototype development method, which includes requirement analysis, prototype design, system implementation, program coding, and testing. The tracer study system is developed using PHP 7.0 programming language with CodeIgniter framework and MySQL database. Based on the conducted development analysis, this application improves the average time efficiency compared to the previous system. Additionally, the use of this application reduces costs in generating alumni data reports and facilitates alumni data management at SMKN 2 GARUT. This tracer study information system effectively manages alumni data, provides appropriate control, and can be accessed through internet technology.

Abstract

Digital marketing has become crucial for Micro, Small, and Medium Enterprises (MSMEs), especially when facing the challenges of the technological era. With technological advancements, the internet, and the digital revolution, MSMEs must be prepared to understand the use of social media to develop increasingly advanced technologies and meet the technological needs for small business development in the future. However, not all MSME operators in the Desa Jati community have yet been able to leverage technology to support their businesses. Addressing this issue, the aim and solution of this research is to provide Digital Marketing and Strategy assistance to these MSMEs. The program has shown significant positive impacts. Participants in the training have experienced improvements in their digital marketing knowledge and skills, as evidenced by their performance in evaluations.

Abstract

Digitalisasi layanan fasilitas kesehatan menjadi tuntutan yang tidak dapat dihindari pada era abad ke-21, termasuk pada layanan Rekam Medis Elektronik (RME) di lingkungan Fasilitas Pelayanan Kesehatan Tingkat Pertama (FKTP). Urgensi audit keamanan RME di FKTP semakin meningkat seiring dengan maraknya insiden kebocoran data kesehatan dan belum meratanya penerapan standar keamanan informasi di tingkat primer. Penelitian ini bertujuan untuk mengaudit keamanan sistem informasi RME pada UPT Puskesmas Cibiuk guna mengevaluasi proses tata kelola perlindungan privasi data pasien yang masih berjalan tanpa standar keamanan baku dan rentan terhadap kebocoran akses. Metode yang digunakan adalah Audit Sistem Informasi melalui pendekatan Gap Analysis (Analisis Kesenjangan), yang dijalankan dengan mengevaluasi 8 kontrol pada Annex A.6 People Controls dan 23 kontrol internal pada Annex A.8 Technological Controls ISO/IEC 27001:2022. Subjek penelitian adalah pengelola IT dan tenaga medis pengguna sistem di UPT Puskesmas Cibiuk, sedangkan objek penelitian adalah sistem RME yang saat ini digunakan secara aktif di poli pelayanan. Hasil penelitian menunjukkan bahwa tingkat kematangan (maturity level) keamanan sistem berada pada rata-rata 2.30 (Repeatable) dengan persentase kesesuaian sebesar 47,09%. Temuan risiko tertinggi ditemukan pada kontrol backup yang belum diuji restore dengan risk score 20 (Sangat Tinggi). Celah keamanan paling signifikan ditemukan pada praktik berbagi kata sandi (password sharing) antar perawat dan ketiadaan enkripsi pada proses pencadangan (backup) data. Implementasi audit terbukti efektif memetakan kerentanan sistematis pada operasional puskesmas. Penelitian ini menyimpulkan bahwa kerangka kerja ISO/IEC 27001:2022 sangat relevan diterapkan pada evaluasi sistem informasi berskala layanan kesehatan primer karena ketatnya standar yang mengakomodasi perlindungan data medis.     Audit of Electronic Medical Record (EMR) Information System Based on ISO/IEC 27001:2022 Criteria at UPT Puskesmas Cibiuk   Abstract The digitalization of healthcare facilities has become an unavoidable demand in the 21st century, including Electronic Medical Record (EMR) services in Primary Healthcare Facilities. The urgency of auditing EMR security in primary healthcare facilities is increasing along with the rise in health data breach incidents and the uneven implementation of information security standards at the primary level. This study aims to audit the security of the EMR information system at UPT Puskesmas Cibiuk to evaluate the governance of patient data privacy protection, which is currently running without standard security protocols and is vulnerable to access breaches. The method used is Information Systems Audit through a Gap Analysis approach, conducted by evaluating 8 controls in Annex A.6 People Controls and 23 internal controls in Annex A.8 Technological Controls of ISO/IEC 27001:2022. The research subjects were IT administrators and medical personnel using the system at UPT Puskesmas Cibiuk, while the object of research was the EMR system currently actively used in outpatient clinics. The results showed that the system's security maturity level is at an average of 2.30 (Repeatable) with a compliance percentage of 47.09%. The highest risk finding was found in the backup control that had not been restore-tested, with a risk score of 20 (Very High). The most significant security vulnerabilities were found in the practice of password sharing among nurses and the lack of encryption in the data backup process. The implementation of the audit proved effective in mapping systematic vulnerabilities in the community health center's operations. This study concludes that the ISO/IEC 27001:2022 framework is highly relevant for evaluating information systems at the primary healthcare level due to its strict standards accommodating medical data protection.
