Abstract

Abstract: Data security is crucial in the digital era, where cloud computing has become the primary solution for organizations to efficiently store and process data. However, the increasing use of cloud computing also poses significant risks related to data security and privacy. The purpose of this study is to identify challenges and solutions in maintaining data security in cloud computing systems. The method used is a systematic literature review and comparative analysis of various trusted academic sources. The results reveal key threats such as misconfigurations, unauthorized access, and data leaks, which are exacerbated by weak identity management. The study also evaluates mitigation mechanisms such as end-to-end encryption, multi-factor authentication, and a shared responsibility model between cloud service providers and users. These findings can guide the design of effective and adaptive security strategies and policies to support a secure and sustainable digital transformation. Keyword: data security; information systems; cloud computing; encryption; authentication.

Abstract

Abstract: This research aims to reveal the dynamics of student behavior in the context of working on group assignments in the lecture environment. Through a qualitative approach, various patterns of student participation were found that reflected adaptation strategies to collective responsibility, procrastination tendencies, and social dependence. Data was collected through in-depth interviews and participatory observation of student group activities in completing academic assignments. The results of the study showed that students tended to choose easy tasks, postpone work until they were close to the deadline, avoid leadership positions, and adjust the intensity of contributions based on the quality of group members. This phenomenon indicates the diffusion of social responsibility and efficiency strategies in the context of collaborative learning. This research provides implications for lecturers to design an assessment system and evaluation mechanism that fosters a sense of personal responsibility in group work.Keyword: Group Assignments, Student Participation, Procrastination, Social Dependence, Collective ResponsibilityAbstrak: Penelitian ini bertujuan untuk mengungkap dinamika perilaku mahasiswa dalam konteks pengerjaan tugas kelompok di lingkungan perkuliahan.

Abstract

Abstract: The amendment to the Minister of Health Regulation on medical records requires all healthcare facilities in Indonesia to implement Electronic Medical Records (EMR) no later than December 31, 2023. Many clinics, as part of these facilities, still rely on a file-based approach, resulting in scattered data that are difficult to retrieve, prone to duplication, and often inaccurate. This study aims to analyze the use of MySQL in designing a web-based EMR database. The method employed is a Systematic Literature Review (SLR), selecting articles based on inclusion and exclusion criteria, yielding 20 relevant journals. MySQL was chosen because it is an open-source database management system (DBMS) licensed under GPL, supports multi-user access, offers fast query performance, and provides adequate security features. Its advantages include easy distribution, compliance with standard SQL, and reliable performance for managing medical data. However, limitations such as inefficient decentralized configuration and longer execution times with large-scale data must be considered. The database design process follows five stages: Requirement, Design, Implementation, Verification, and Maintenance. The findings indicate that MySQL is suitable for EMR database design due to its functional strengths and flexibility, although large-scale optimization remains a challenge.Keywords: Electronic Medical Records, MySQL, Database Abstrak: Perubahan Peraturan Menteri Kesehatan tentang rekam medis mewajibkan seluruh fasilitas pelayanan kesehatan (fasyankes) di Indonesia menyelenggarakan Rekam Medis Elektronik (RME) paling lambat 31 Desember 2023. Klinik sebagai salah satu fasyankes masih banyak yang mengandalkan pendekatan file-based, sehingga data tersebar, sulit dicari, rawan duplikasi, dan sering tidak akurat. Penelitian ini bertujuan menganalisis pemanfaatan MySQL dalam perancangan database RME berbasis web. Metode yang digunakan adalah Systematic Literature Review (SLR) dengan menyeleksi artikel sesuai kriteria inklusi dan eksklusi, dan diperoleh 20 jurnal relevan. MySQL dipilih karena merupakan sistem manajemen database (DBMS) open source berlisensi GPL, mendukung multiuser, memiliki kecepatan query yang baik, serta fitur keamanan yang memadai. Kelebihan MySQL meliputi kemudahan distribusi, dukungan standar SQL, dan performa yang andal untuk pengelolaan data medis. Namun, kelemahan seperti konfigurasi desentralisasi yang kurang efisien dan peningkatan waktu eksekusi pada data berskala besar perlu diperhatikan. Proses perancangan database mengikuti lima tahap: Requirement, Design, Implementation, Verification, dan Maintenance. Hasil kajian menunjukkan MySQL layak digunakan untuk perancangan database RME karena keunggulan fungsional dan fleksibilitasnya, meskipun optimalisasi skala besar tetap menjadi tantangan.Kata kunci: Rekam Medis Elektronik, MySQL, Database

Abstract

Abstract: This study aims to examine the practices and symbolic meanings within the healing rituals of the Dayak tribe in Central Kalimantan, as documented in the ancient manuscript "Amiroe." This research employs a philological approach with a qualitative descriptive method to interpret the text's content and understand the cultural values embedded within it. The findings indicate that the healing process is performed by a balian (shaman) who acts as an intermediary between humans and the spirit world through three main stages: preparation, execution, and recovery. During the execution stage, the balian performs ritual movements, such as dancing around the altar and leaping when an earth spirit approaches, while chanting magical incantations to summon benevolent spirits and expel malevolent ones. According to Dayak beliefs, illness occurs when a person's soul leaves the body and encounters a lonely spirit, consequently causing sickness. Even if the ritual fails and the patient passes away, the community continues to believe in the spiritual power behind the process. Through philological analysis, symbolic anthropology, and personalistic ethnomedicine, this study concludes that the "Amiroe" manuscript not only records traditional healing practices but also reflects the Dayak people's worldview and belief system regarding the balance between the body, soul, and spirit.Keywords: Philology, Healing Ritual, Dayak Tribe, Amiroe Manuscript, Symbolic AnthropologyAbstrak: Penelitian ini bertujuan untuk mengkaji praktik dan makna simbolik dalam ritual penyembuhan masyarakat Suku Dayak di Kalimantan Tengah sebagaimana tercantum dalam naskah kuno Amiroe. Penelitian ini menggunakan pendekatan filologis dengan metode deskriptif kualitatif untuk menafsirkan isi teks dan memahami nilai-nilai budaya yang terkandung di dalamnya. Hasil penelitian menunjukkan bahwa proses penyembuhan dilakukan oleh balian sebagai perantara antara manusia dan dunia roh melalui tiga tahap utama, yaitu persiapan, pelaksanaan, dan pemulihan. Pada tahap pelaksanaan, balian melakukan gerakan ritual, seperti menari mengelilingi altar dan melompat ketika roh bumi mendekat, serta melafalkan mantra magis untuk memanggil roh baik dan mengusir roh jahat. Menurut kepercayaan masyarakat Dayak, penyakit terjadi ketika jiwa seseorang meninggalkan tubuh dan bertemu dengan roh yang kesepian, sehingga menyebabkan sakit. Jika ritual gagal dan pasien meninggal, masyarakat tetap mempercayai kekuatan spiritual di balik proses tersebut. Melalui analisis filologis, antropologi simbolik, dan etnomedisin personalistik, penelitian ini menyimpulkan bahwa naskah Amiroe bukan hanya merekam praktik penyembuhan tradisional, tetapi juga mencerminkan pandangan hidup dan sistem kepercayaan masyarakat Dayak tentang keseimbangan antara tubuh, jiwa, dan roh.Kata Kunci: filologi, ritual penyembuhan, Suku Dayak, naskah Amiroe, antropologi simbolik.

Abstract: Availability of motorcycle spare parts in CV. Solid Mandiri Cemerlang must be monitored to avoid product shortages. The problem that occurs in reporting regarding Most of the items purchased by Most of the customers is under control. Processing incoming and outgoing goods that are not processed by the system requires goods management techniques. The more complete the types of spare parts, customer needs will be met. The collection of available spare parts will be divided into several groups to get the spare parts that customers have purchased the most for each transaction. Data mining is sourced from raw database. This causes problems in databases which tend to be dynamic, complete and large. The K-means Clustering algorithm is capable and effective for finding clusters in data. This calculation will determine the number of clusters at the calculation center and the maximum iteration of data that has been entered into the system. The purpose of implementing the K-means algorithm is to find the value of the goods purchased by the majority of customers so that it makes it easier to provide spare parts.

Abstract: This research, entitled "Design and Construction of Hydrogen Gas Production Process Through Water Electrolysis Based on Internet of Things (IoT)", aims to design a hydrogen production system and IoT-based remote monitoring. The electrolysis process is carried out using stainless steel electrodes with KOH electrolyte solution and is powered by a DC power supply. The system is equipped with an MQ-8 sensor to detect hydrogen gas concentration and a K-type thermocouple temperature sensor with a MAX6675 module to monitor the solution temperature. Sensor data is processed by an ESP32 microcontroller, displayed via LCD, and sent to the Blynk application for real-time monitoring. Test results show that the increase in voltage and current is directly proportional to the increase in temperature and the concentration of hydrogen gas produced. At a voltage of 31 V with a current of around 0.48 A, hydrogen gas production of 293 ppm with a temperature of 31.8 C was obtained. The designed system is proven to be able to produce hydrogen gas through water electrolysis, while providing effective, efficient, and remotely accessible IoT-based monitoring.Keyword: Water Electrolysis, Hydrogen Gas, MQ-8 Sensor, K-Type Thermocouple, ESP32, Internet of Things (IoT)Abstrak: Penelitian ini berjudul Rancang Bangun Proses Produksi Gas Hidrogen Melalui Elektrolisis Air Berbasis Internet of Things (IoT) yang bertujuan merancang sistem produksi hidrogen sekaligus monitoring jarak jauh berbasis IoT.
