Abstract

Telah dilakukan penelitian kinetika vitamin B kompleks pada proses pembuatan tahu dan oncom merah.Penelitian ini bertujuan untuk melihat kandungan beberapa vitamin B kompleks pada oncom merahdibandingkan pada tahu setelah proses fermentasi dari ampas tahu. Pengujian sampel ampas tahudiambil dari satu pabrik tahu dan pabrik oncom dimana bahan baku ampas tahunya berasal dari pabriktahu yang sama. Pengujian meliputi analisis kadar air dan analisis kadar vitamin B komplek. Hasilanalisis menunjukkan bahwa dari 10 kg kedelai dalam 1 kali produksi hanya 66,66% yang menjaditahu, sisanya 33,32% sebagai ampas tahu dan 0,901% sebagai air tahu. Pada pengolahan ampas tahumenjadi oncom merah terjadi penambahan bobot yang sangat berarti yaitu sebesar 345,19%. Padaproses pembuatan tahu, terjadi penurunan kadar vitamin B kompleks sangat tinggi dibandingkan dalamkacang kedelai yaitu vitamin B1 berkurang sebesar 41,07%; vitamin B2 berkurang 35,5%; vitaminB3 berkurang 99,08% dan vitamin B6 tidak terdeteksi lagi. Pada ampas tahu, kandungan vitamin Bkomplek yang masih ada yakni 19,59% (vitamin B2) dan berkisar antara 4-22% (vitamin B1; B3; B6)yang terkandung pada air tahu. Pada proses pembuatan oncom merah terjadi peningkatan vitamin Bkomplek yang sangat tinggi yakni untuk vitamin B1 dari tidak terdeteksi menjadi 234,78 mg; vitaminB2 dari 18,9 mg menjadi 304,89 mg; vitamin B3 dari tidak terdeteksi menjadi 517,26 mg dan vitaminB6 dari tidak terdeteksi menjadi 45,797 mg. Dari hasil penelitian ini membuktikan bahwa peningkatankadar vitamin B kompleks pada oncom merah terjadi karena adanya aktifias mikrobia selama prosesfermentasi.

Abstract

Background: Vitamin D supplementation to prevent Metabolic Syndrome (MetS) has been widely implemented in developed countries and is now being introduced in developing countries. However, recent studies have shown no association between vitamin D and MetS in adults. Objectives: This study aims to obtain a profile of vitamin D values ​​in adults and explore vitamin D status in MetS patients, MetS components, and healthy adults. Methods: This research design was a cross-sectional study, utilizing both secondary and primary data from the research on the Risk Factors for Non-Communicable Diseases (RF-NCD) longitudinal study in 2021. Serum 25(OH)D levels in 956 adult respondents were determined by Enzyme-linked Immune Assay (ELISA) analysis using Stored Biological Material (SBM) serum from the 2021 RF-NCD longitudinal study. The ANOVA test was used to determine differences in vitamin D levels in various physiological conditions of respondents (MetS, MetS components, and healthy people). Results: A total of 68.5% of respondents had inadequate (deficiency and insufficiency) serum vitamin D levels, with an average of 26.5 ng/mL. The average vitamin D levels between MetS patients, MetS components, and healthy people were not significantly different (p-value>0.05). However, the number or percentage of respondents with 25(OH)D deficiency in the MetS group (12.1%) was higher than other physiological conditions. Conclusions: Most of the respondents in this study have inadequate vitamin D levels. The average vitamin D levels did not differ between physiological conditions. Further studies are needed on other micronutrient factors that affect the incidence of MetS and its components.

Abstract

An understanding of factors that affect the recovery time from a disease is important for the community, medical staff, and also the government. This research analyzed factors that affect the recovery time of Covid-19 sufferers in West Sumatra. In addition, the consumption of a herbal made from Sungkai leaves, which is believed by some people in West Sumatra to accelerate the healing from Covid-19, was also included in the analysis. The recovery time here was categorized into two classes (binary): 1 for within 2 weeks, and 0 for more than 2 weeks. The methods used were logistic regression and geographically weighted logistic regression (GWLR). GWLR provides estimates of parameters for each location. The data used in this study is Covid-19 data of 2021 taken from the Regional Research and Development Agency (Litbangda) of West Sumatra with a total of 764 observations collected from 19 regencies/cities in West Sumatra. The results showed that there was no difference between the logistic regression model and the GWLR models based on the values of AIC and the ratio of deviance and degrees of freedom (df). The addition of spatial factors through GWLR models did not provide additional information regarding the recovery of Covid-19 sufferers within 2 weeks or more than 2 weeks. The logistic regression model gives the result that, at significance level α = 10%, residence, vaccination status, and symptoms significantly affect the recovery time within 2 weeks or more for Covid-19 sufferers, while other variables, namely sex, age, Sungkai leaves consumption status, and ginger consumption status have no significant effects.
