Abstract

The health laboratory is one of the health services for the community in helping to establish a diagnosis, monitoring treatment results, and determining the prognosis of a disease. Control serum is very important for assessing performance in the laboratory, including instrument and reagent quality. Some laboratories use pooled serum as control serum for daily examination. Albumin is the most abundant plasma protein in the human body, which is about 55-60% and the total normal serum protein level is 3.8-5.0%. This study aims to test the stability of pooled sera on examination of albumin stored in the refrigerator at a temperature of 2 - 8ºC for 2 weeks. This research method uses observational research methods with precision data analysis techniques (accuracy). The results of the study of examining albumin levels using the Bromcresol Green (BCG) method obtained serum stability results on day 1 to day 5, where the CV value from the albumin level examination entered the maximum CV value on albumin, which was 6. The CV value for the 5th day covers, day 1 to day 2 = 1.99. Day 1 to day 3 = 2.17. Day 1 to day 4 = 4.27. And day 1 to day 5 = 4.84. On day 6 to day 14 and so on, the serum is found to be unstable and the value does not enter the maximum CV value.

Abstract

Kabupaten Kerinci, dengan keberadaan Gunung Api aktif, rentan terhadap gempa bumi. Meskipun demikian, kawasan lereng bukit, terutama di Kayu Aro Barat, masih dihuni oleh banyak penduduk. Penelitian ini bertujuan untuk mengidentifikasi potensi kerentanan tanah di wilayah tersebut menggunakan metode mikrotremor. Hasil penelitian menunjukkan adanya variasi kerentanan tanah yang signifikan. Bagian barat laut memiliki kerentanan tanah yang lebih rendah (0,40-0,85), sedangkan bagian tenggara memiliki kerentanan yang lebih tinggi (2,19-2,64). Nilai Peak Ground Acceleration (PGA) maksimum tercatat di bagian tenggara dengan rentang 251-1729 mgal. Temuan ini mengindikasikan bahwa wilayah tenggara Kayu Aro Barat memiliki potensi risiko gempa bumi yang lebih tinggi dibandingkan wilayah lainnya. Meskipun nilai PGA masih berada dalam kategori aman, perlu diingat bahwa aktivitas seismik dapat memicu pergerakan tanah dan longsor, terutama di daerah dengan topografi curam dan kondisi tanah yang labil seperti di Kayu Aro Barat. Oleh karena itu, diperlukan kajian lebih lanjut dan upaya mitigasi risiko untuk melindungi keselamatan masyarakat.

Abstract

This study aims to identify and analyze the influence of financial literacy, service features, and the influence of convenience on the decision to use Gopay with a case study of employees working in Cikarang. Primary data was collected through a questionnaire involving 89 respondents and quantitatively analyzed using the Smart Partial Least Square - Structural Equation Model (SMART PLS). The results of the analysis show that financial literacy, and the influence of convenience have an influence on the decision to use Gopay, while service features and service features as moderation have no influence on the decision to use Gopay. These findings make a theoretical contribution to the development of e-wallet adoption models and practical implications for fintech service providers in designing product and service development strategies. The study also highlights the importance of financial literacy education and the development of easy-to-understand features to increase e-wallet adoption in Indonesia.
