Abstract


Abstract: Protein is required to provide amino acids for nitrogen formation. Urea is the major disposal form of amino groups derived from amino acids. The nitrogen of urea is derived from amonia and aspartatedue to the action of five enzyme-catalyzed reactions of urea cycle. Concentration of urea in blood mainly describes the balance between formation of urea and protein catabolism as well as urea excretion by the kidneys. Vegetarian lacto-ovo is a type of vegetarians who does not consume animal proteins except for milk and eggs, and all plant proteins. This study aimed to obtain blood urea levels among lacto-ovo vegetarians. This was a descriptive study with a cross-sectional design. Respondents were obtained by using total sampling method. This study was coducted in Klabat University, Airmadidi. Twentyfive respondents were involved in the study. The results showed that 19 respondents (76.0%) had normal blood urea level and 6 respondents (20%) had low blood urea levels; no respondent (0%) had a high blood urea level. Conclusion: Blood urea levels of most lacto-ovo vegetarians were within normal level.

Abstrak: Protein dibutuhkan untuk menyediakan asam amino yang akan digunakan untuk memroduksi senyawa nitrogen sebagai penggganti nitrogen yang telah dikeluarkan dari tubuh dalam bentuk urea. Urea merupakan produk akhir dari metabolisme nitrogen yang penting pada manusia yang disintesis dari amonia, dan aspartat melalui lima reaksi enzim-katalis dari siklus urea. Konsentrasi urea dalam darah terutama menggambarkan keseimbangan antara pembentukan urea dan katabolisme protein serta ekskresi urea oleh ginjal. Vegetarian lacto-ovo yaitu vegetarian yang tidak mengonsumsi sumber protein hewani selain susu, telur, dan juga mengonsumsi semua sumber protein nabati. Penelitian ini bertujuan untuk mengetahui gambaran kadar urea darah pada vegetarian lacto-ovo. Jenis penelitian ini deskriptif dengan desain potong lintang. Penelitian ini dilakukan di Universitas Klabat Airmadidi. Terdapat 25 responden yang diperoleh melalui total sampling. Hasil penelitian mendapatkan 19 responden (76,0%) dengan kadar urea darah normal dan 6 responden (20%) dengan kadar urea darah rendah; tidak ditemukan responden (0%) dengan kadar urea darah tinggi. Simpulan: Gambaran kadar urea nitrogen darah pada vegetarian lacto-ovo sebagian besar normal.
