Abstract

Prevalensi kanker rahim di Indonesia masih tinggi. Protein Bcl-2 salah satu protein yang menghambat apoptosis melalui jalur mitokondria. Pada kanker serviks terjadi mutasi p53 sehingga Bcl-2 mengalami ekspresi berlebihan.Terapi kanker serviks menggunakan bahan kimia dapat menimbulkan banyak efek samping. Senyawa anti kanker dari bahan alam yang  sedikit menimbulkan efek samping diharapkan mampu mempengaruhi ekspresi protein Bcl-2. Pada semua jenis Sargassum sp. mengandung fukosantin dengan kadar tinggi. Fukosantin dapat menurunkan ekspresi protein Bcl-2 pada sel kanker. Tujuan penelitian ini adalah membuktikan bahwa pemberian ekstrak alga coklat (Sargassum sp.) dapat menghambat ekspresi Bcl-2 pada kanker serviks (sel HeLa). Penelitian ini merupakan penelitian eksperimental laboratorik dengan rancangan true experimental. Sampel yang digunakan adalah sel HeLa yang terbagi atas 1 kontrol dan 3 perlakuan. Kelompok I adalah kontrol sel HeLa. Kelompok II-IV diberi perlakuan ekstrak alga coklat dengan kadar yang berbeda-beda (31,25 µg/ml, 62,5 µg/ml, dan 125 µg/ml). Semua kelompok diinkubasi selama 24 jam. Parameter yang diukur adalah ekspresi Bcl-2 pada sel HeLa yang dideteksi secara imunohistokimia. Hasil analisis statistika menunjukkan bahwa ekstrak alga coklat menurunkan eskspresi Bcl-2 sel HeLa secara signifikan (ANOVA, p = 0,000; R² = 0,947). Penurunan ekspresi Bcl-2 mulai terlihat sejak pemberian ekstrak Sargassum dengan kadar 31,25 µg/ml. Pemberian ekstrak alga coklat kadar 31,25 µg/ml, 62,5 µg/ml, dan 125 µg/ml menurunkan ekspresi Bcl-2 sebesar 21 %, 44 %, dan 68 %. Kesimpulan penelitian ini adalah ekstrak alga coklat (Sargassum sp.) mampu menurunkan ekspresi Bcl-2 sel HeLa dengan kadar efektif terendah 31,25 µg/ml. Kata kunci: Bcl-2, Ekstrak alga coklat (Sargassum sp), Sel HeLa.

Abstract

Background:   Forensic examination of semen in cases of sexual intercourse (e.g., sexual assault) aims to detect the presence of spermatozoa or male-specific biomarkers in vaginal swab samples from victims. Conventional methods, including microscopic examination with staining and chemical tests (acid phosphatase and prostate-specific antigen/PSA), are routinely used but have limitations in sensitivity and specificity. In the past five years, advancements have emerged in semen detection technology, including Loop-mediated Isothermal Amplification (LAMP), Y-STR (Y chromosome short tandem repeat) analysis, sperm-specific aptamers, and Convolutional Neural Networks (CNN) for automated identification. Objective: This review article aims to summarize current literature (2019–2024) regarding spermatozoa detection methods in vaginal swab samples, covering both conventional and innovative techniques. Methods: Literature was searched through international and national databases using relevant keywords including “forensic sperm detection,” “vaginal swab semen,” “LAMP for sperm,” “Y-STR sexual assault,” “aptamer sperm detection,” and “CNN sperm microscope” within the publication range of 2019–2024. Results: Recent studies confirm that microscopy (histological staining) and chemical testing (acid phosphatase and PSA) remain the initial standard for semen examination. However, both are presumptive and susceptible to false-positive or false-negative results. LAMP and Y-screen methods demonstrated high sensitivity in detecting male-specific DNA, comparable to Y-STR profiling. Fluorescent DNA aptamers selectively bind to sperm cells, enhancing detection speed and accuracy. The application of CNN to colored microscopic images has enabled automated “sperm hunting” with accuracy exceeding 90%, significantly expediting laboratory analysis. Conclusion:  Conventional methods such as microscopy and chemical assays remain essential in forensic semen analysis, but show limited reliability in low-sperm samples or cases involving azoospermic perpetrators. Emerging techniques based on DNA, biochemical markers, and artificial intelligence offer improvements in sensitivity, specificity, and detection efficiency. Integration of multi-method approaches is recommended to optimize outcomes. Further standardization and research are needed to facilitate widespread implementation of these novel technologies in forensic laboratories.

Abstract

Hypertension is a non-communicable disease that is a leading cause of global morbidity and mortality. In Indonesia, the prevalence of hypertension continues to rise, particularly among the productive and elderly populations. This community service activity aims to conduct early detection and provide education on hypertension through blood pressure screening in Kasemen Village, Serang City, Banten Province. The method employed is a participatory approach involving faculty members and medical students from the Faculty of Medicine and Health Sciences at UNTIRTA. A total of 247 village residents participated in this activity, and from 230 valid data, it was found that 51.30% of respondents had hypertension. The highest proportion of hypertension was observed among the elderly group (71.6%) and men (80%). In addition to blood pressure measurement, education on the importance of regular blood pressure monitoring and healthy lifestyle changes was also provided to raise community awareness. The results of this activity demonstrate that community-based screening, combined with health education, is an effective strategy for preventing and controlling hypertension, while also serving as a field-based learning opportunity for medical students.
