Abstract

Perlindungan data pribadi merupakan salah satu hak asasi manusia yang tertuang dalam UUD 1945 Pasal 28G. Di Indonesia, terdapat laporan data informasi kesehatan bocor dijual di forum daring pada  kasus BPJS Kesehatan (2021), dari 279 juta penduduk Indonesia. Ini dapat  memicu berbagai kejahatan cyber, mulai dari pencurian identitas, pemerasan, hingga penipuan berbasis klaim asuransi kesehatan. Tujuan pengabdian pada masyarakat ini adalah untuk memberikan informasi dan meningkatkan kesadaran masyarakat tentang pentingnya layanan e-Health dan perlindungan data pribadi dalam penggunaan platform digital kesehatan. Metode pelaksanaan diawali dengan tanya jawab seputar kesehatan, terutama  perawatan & pemeriksaan e-Health, kemudian diskusi layanan digital kesehatan. Selanjutnya sosialisasi serta praktik penggunaan aplikasi e-Health pada masyarakat untuk memberikan informasi mengenai manfaat layanan serta kermudahan aksesnya. Hasil informasi dan diskusi dari warga masyarakat tanggal 17 - 20 Juli 2024, kerjasama dengan Mitra menyatakan 80% (80 orang ) telah mengetahui adanya aplikasi layanan kesehatan  e-Health yang dapat memudahkan akses pemeriksaan jarak jauh, 20% (20 orang) pernah menggunakan aplikasi e-Health untuk konsultasi. Hasil sosialisasi dari brosur perlindungan data pribadi, masyarakat telah memahami untuk menjaga kerahasiaan password, dan sadar untuk menyimpan data riwayat kesehatan dengan baik. Simpulan, masyarakat perlu menjaga data pribadi dalam penggunaan e-Health karena melibatkan informasi riwayat kesehatan seseorang. Disarankan, sebaiknya masyarakat mau membaca ketentuan serta kebijakan privasi di aplikasi kesehatan, tentang ketentuan penggunaanya, sehingga tidak salah langkah dalam menggunakan platform digital ini yang bisa berdampak fatal.

Hasil ini menunjukkan bahwa material tersebut memiliki sifat mekanik yang kuat, kaku, dan layak digunakan sebagai struktur utama chassis kendaraan ringan. Pada analisis deformasi, tegangan, dan safety factor menggunakan perangkat lunak ANSYS diperoleh nilai deformasi maksimum sebesar 40,05 mm, tegangan maksimum sebesar 7,24 MPa serta menghasilkan safety factor sebesar 43,86. Hasil ini menandakan struktur sangat aman untuk digunakan dalam kondisi pembebanan statis pada kendaraan KMHE. This study aims to design and simulate the KMHE car chassis using Autodesk Inventor and ANSYS software. The KMHE car chassis is designed using a space frame model with the main material being black steel hollow. Technical parameters such as tensile tests, deformation, stress, and safety factor were used to support the simulation process and analysis of the KMHE vehicle's mechanical performance. The results showed that tensile tests using black hollow steel as the primary material for the KMHE chassis yielded a yield strength of ±317.5 MPa, an ultimate tensile strength of ±393.6 MPa, and a modulus of elasticity of ±19,226 MPa. These results indicate that the material possesses strong and stiff mechanical properties, making it suitable for use as the primary structure of a light vehicle chassis. Analysis of deformation, stress, and safety factor using ANSYS software yielded a maximum deformation of 40.05 mm, a maximum stress of 7.24 MPa, and a safety factor of 43.86. These results indicate that the structure is very safe for use under static loading conditions in KMHE vehicles.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh variasi fraksi volume dan perlakuan awal serat terhadap kekuatan uji tarik pada material komposit berbasis serat batang pisang. Material komposit ini dikembangkan sebagai alternatif bahan penguat alami yang ramah lingkungan dan memanfaatkan limbah biomassa. Serat batang pisang diberi perlakuan alkali dengan variasi larutan NaOH 2%, 4%, 6% untuk meningkatkan kualitas antarmuka antara serat dan matriks resin epoxy. Variasi fraksi volume serat yang digunakan adalah 20%, 40%, dan 60%. Proses pembuatan komposit dilakukan dengan metode hand lay-up, sedangkan pengujian sifat mekanik meliputi uji tarik (ASTM E8). Hasil penelitian adalah pengujian pada fraksi volume 40% yang menghasilkan sifat mekanik terbaik untuk aplikasi struktural. This study aims to determine the effect of variations in volume fraction and fiber pretreatment on the tensile strength of banana stem fiber-based composite materials. This composite material was developed as an alternative environmentally friendly natural reinforcing material and utilizes biomass waste. Banana stem fibers were treated with alkali with variations NaOH solution of 2%,4%, 6% to improve the quality of the interface between the fiber and the epoxy resin matrix. The variations in fiber volume fraction used were 20%, 40%, and 60%. The composite manufacturing process was carried out using the hand lay-up method, while mechanical property testing included tensile testing (ASTM E8). The results of the study were testing at a volume fraction of 40% which produced the best mechanical properties for structural applications.

Abstract

Bacterial infections, such as S. aureus and E. coli, remain a global health issue, particularly concerning bacterial resistance, which often leads to serious complications. One approach to address this problem is the development of Metal Organic Frameworks (MOFs), known for their high conductivity and antibacterial activity. Zn-based MOFs are known to possess strong antibacterial activity because Zn²⁺ ions can damage bacterial cell membranes, disrupt enzymatic processes, and induce oxidative stress. In comparison, Zr-based MOFs are well known for their excellent chemical stability and biocompatibility. In this study, hydrogels containing three types of MOFs-Zn-BDC, Zn-Fer, and Zr-BDC were developed. This research aims to synthesize and characterize alginate-gelatin hydrogels containing MOFs and evaluate their antibacterial activity. The results indicate that the modification of alginate-gelatin hydrogels with MOFs has been successfully synthesized, as evidenced by FTIR, XRD, and SEM-EDS analyses. The materials successfully produced include Hy/Zn-BDC, Hy/Zn-Fer, and Hy/Zr-BDC. Antibacterial activity testing shows that adding MOF into the hydrogel matrix significantly increases the inhibition against S. aureus and E. coli compared to the hydrogel without MOF. Among the three MOF variants, Hy/Zn-BDC showed the highest antibacterial activity, followed by Hy/Zn-Fer and Hy/Zr-BDC. Specifically, Hy/Zn-BDC inhibited S. aureus growth by 95% and E. coli by 100%, accompanied by the lowest effective inhibitory concentration values (2.0 mg/mL and 2.4 mg/mL, respectively). These results demonstrate the high effectiveness of Zn-based MOF in enhancing the antibacterial performance of the hydrogel as well as its potential development for wound dressing applications.

Abstract

The Chow Kit settlement in Kuala Lumpur, Malaysia, is characterized by a population of homeless and low-to-no-income residents. As such, this area frequently becomes a focus for social institutions implementing Community Service Responsibility (CSR) programs, particularly in the health domain. This CSR initiative represents a collaborative effort between USIM Malaysia (Faculty of Dentistry) and the Faculty of Pharmacy (IIK Bhakti Wiyata Kediri, Indonesia), focusing on educational interventions to prevent and reduce dental caries through the use of herbal mouthwash formulations. Dental caries has emerged as a prevalent oral health concern with a significant impact on overall health. The condition originates from the formation of Streptococcus mutans bacterial biofilms, which are typically exacerbated by excessive consumption of sugary foods and tobacco use. The community service methodology employed participatory counseling and educational approaches, utilizing purposive sampling techniques. Evaluation of the program demonstrated enhanced comprehension among the 22 participants, with mean pre-test scores of 57.39 improving to 79.09 post-intervention, reflecting a 21.7% increase. While some participants maintained baseline scores, 86.5% of attendees (19 individuals) achieved improvements exceeding 20 points. Sustainable monitoring and evaluation mechanisms remain essential, given that the participant cohort primarily consists of homeless individuals whose transient living circumstances often preclude consistent maintenance of personal oral hygiene practices.
