Abstract

Cemaran mikroba dalam olahan pangan dapat menyebabkan keracunan makanan. Salah satu mikroba pangan yang dapat ditemukan ialah E. coli (mikroba indikator sanitasi) dan S. typhi (mikroba patogen). Pada November 2019, sebanyak 16 balita di Desa Bangbayang dilaporkan mengalami keracunan makanan akibat PMT bubur ayam di posyandu. Maka dari itu, penelitian ini bertujuan untuk mengetahui ada tidaknya kontaminasi bakteri pada bubur bayi industri rumah tangga di sekitar Cempaka Putih. Penelitian ini menggunakan metode Total Plate Count dengan jenis penelitian deskriptif, pendekatan observasional, dan teknik purposive sampling pada 5 sampel bubur bayi di sekitar Cempaka Putih yang diperoleh melalui pelayanan delivery order makanan. Berdasarkan hasil uji Angka Lempeng Total dan uji media kultur mikroba (Agar Darah Plat, Endo, Nutrient, dan Salmonella-Shigella), tidak ditemukan adanya pertumbuhan bakteri dalam setiap 25 gram sampel. Menurut kriteria Standar Nasional Indonesia Nomor 7388 Tahun 2009 dan Peraturan Badan Pengawas Obat dan Makanan Nomor 13 Tahun 2019, kelima sampel bubur bayi di sekitar Cempaka Putih mempunyai kualitas higiene dan sanitasi yang baik karena memenuhi persyaratan negatif cemaran bakteri (TPC < 104 koloni/gram).

Abstract

Background: The impact of Distance learning (DL) during the COVID-19 pandemic on students causes anxiety disorders, excessive worry, and feeling depressed. Meditation or mindfulness is one method to treat a mental disorder. Purposes:This study aimed to determine the relationship between dhikr and the occurrence of somatoform disorders among Yarsi medical faculty students during distance learning. Method: The type of research was descriptive observational with a cross-sectional approach. The study population was YARSI medical students in the 2019 batch, and purposive sampling was conducted. The inclusion criteria were medical students in the 2019 batch who were active and did dhikr, while the exclusion criteria were medical students in the 2019 batch who are not active and not doing dhikr. The tool used in this study was a questionnaire adapted from The Somatic Symptom Scale-8. The data are analyzed univariately and bivariately using SPSS Result: 90.2% of respondents carry out DL for 5-9 hours per day; those who liked DL were 59.7%, and those who did not like DL were 40.2%. Respondents who experienced stress were 96.3%, and 100% percent of respondents had a good perception of dhikr. Respondents who consistently did dhikr were 82.9%. There was no relationship between dzikir and the appearance of somatoform disorders because the P value of the Chi-square test was 0.0079. Conclusion: Respondents mainly experienced mild to severe stress during distance learning, even though the dhikr respondents' perceptions were good. There is no correlation between dhikr and the appearance of somatoform disorder.

Abstract

Stem cell culture requires a highly controlled and sterile environment to ensure cell viability and patient safety. This study aimed to evaluate the microbial contamination levels in the air and the sterility of Biological Safety Cabinets (BSCs) at the YARSI University Stem Cell Laboratory, with the goal of providing recommendations for continuous quality improvement. We used a descriptive quantitative observational approach, collecting air samples from 10 points and two BSCs using a MAS-100 air sampler. Samples were cultured, and the number of Colony Forming Units (CFU) was counted and analyzed against national standards. The results showed a clear distinction between the two environments. Both BSC units demonstrated an sterility level of 0 CFU/m³, confirming the effectiveness of their HEPA filtration. In contrast, the general laboratory area exhibited a varied microbial load, with some areas indicating a need for improved environmental control relative to recommended standards. The identified microorganisms included Candida famata, which is often associated with human flora, and Pseudomonas oryzihabitans, an environmental bacterium. These findings suggest that while BSCs are highly effective barriers, the general lab environment and certain operational practices present areas requiring stricter environmental control. Therefore, infrastructure improvements, such as the installation of an Air Handling Unit (AHU), and the enforcement of stricter Standard Operating Procedures (SOPs) are recommended to maintain overall lab integrity.
