Abstract

Thrombocyte concentrate transfusion was one of the important medical treatments in increasing the number of thrombocytes in patients with medical indications of thrombocytopenia. The monitoring of blood product quality from upstream to downstream must be considered in order to obtain a good quality thrombocyte concentrate. Thrombocyte concentrate was prone to change during storage due to significant changes between in vitro and in vivo conditions. The changes in thrombocyte concentrate quality that commonly occur during storage were the decreased platelet levels, increased of acidity (pH) and turbidity, and loss of thrombocyte swirling in the plasma. Therefore, it was necessary to conduct research to determine the quality of thrombocyte concentrates during the 5-day shelf life to find out whether at the end of the shelf life, these blood products were still suitable for transfusion to the patients. Several tools used in this study were Hematology Analyzer, blood scales, and pH meter. The results of successive studies showed that the thrombocyte concentrate product did not meet the basic quality standards because the number of thrombocytes per unit was below the standard that was set by Regulation of the Ministry of Health of the Republic of Indonesia Number 91 Years 2015.

Abstract

Service quality is action that plays an important role in a health service institution. This study aims to determine quality of donor selection and blood collection services on the satisfaction of blood donors in PMI Yogyakarta Special Region. Type of research is quantitative research with a cross sectional approach. The population in this study is voluntary blood donors who donate blood at PMI and have met the criteria for donor selection and blood collection. Sampling is done by Accidental sampling technique. The study population is all voluntary blood donors who came to UDD PMI Sleman Regency and UDD PMI Kota in August 2023. The number of samples used in this study is 100 respondents. The data collection technique used study was using a questionnaire with a Likert scale. Data analysis techniques carried out using statistical test analysis using chi square. Based on the analysis of the data obtained, characteristics of male blood donors were obtained as many as 79 people (79%). The results of donor satisfaction were obtained 87 (87%) very satisfied, based on donor selection services 51 (51%) Appropriate and blood services 53 (53%) in accordance with donor satisfaction. The results of the chi-square test were obtained in donor selection obtained p-veliu results (0.002) < 0.05 and in the results of the chi-square test blood draw obtained p-veliu results (0.154) > 0.05. means that blood donor satisfaction is influenced by the quality of donor selection services and donor satisfaction is not influenced by the quality of blood collection services.

Abstract

E-learning is recognized as a form of education facilitated through the application of information and communication technologies. The successful implementation of e-learning is influenced by numerous factors. This research aims to identify the determinants of online learning platform acceptance through the lens of the Theory of Planned Behavior (TPB). The study focuses on three independent variables: attitudes, subjective norms, and perceived behavioral control. Positioned as explanatory research with a quantitative emphasis, data were gathered from active students who met specific criteria and were subsequently given access to an online questionnaire. The research sample was obtained through a purposive sampling method. This study employs multiple linear regression analysis, executed through computational means. The hypothesis testing results indicate that two hypotheses—subjective norms on intention and intention on behavior—have a positive and significant influence, suggesting that perceptions from one's social environment can significantly shape users' intentions to engage with online learning platforms. However, the remaining three hypotheses reveal a positive yet insignificant effect, indicating that the variables of behavior and attitude control do not significantly impact the use of online learning platforms. Collectively, the four variables account for only 43.7% of the behavioral outcomes, with the remaining 56.3% likely influenced by other factors beyond the scope of this research. E-learning dikenal sebagai bentuk pendidikan yang difasilitasi melalui penerapan teknologi informasi dan komunikasi. Keberhasilan implementasi e-learning dipengaruhi oleh banyak faktor. Penelitian ini bertujuan untuk mengidentifikasi faktor-faktor penentu penerimaan platform pembelajaran online melalui lensa Theory of Planned Behavior (TPB). Penelitian ini berfokus pada tiga variabel independen: sikap, norma subjektif, dan kontrol perilaku yang dirasakan. Diposisikan sebagai penelitian eksplanatori dengan penekanan kuantitatif, data dikumpulkan dari mahasiswa aktif yang memenuhi kriteria tertentu dan kemudian diberikan akses ke kuesioner online. Sampel penelitian diperoleh melalui metode purposive sampling. Penelitian ini menggunakan analisis regresi linier berganda, yang dilakukan dengan cara komputasi. Hasil pengujian hipotesis menunjukkan bahwa dua hipotesis - norma subjektif terhadap niat dan niat terhadap perilaku - memiliki pengaruh yang positif dan signifikan, yang menunjukkan bahwa persepsi dari lingkungan sosial seseorang dapat secara signifikan membentuk niat pengguna untuk terlibat dengan platform pembelajaran online. Namun, tiga hipotesis lainnya menunjukkan pengaruh yang positif namun tidak signifikan, mengindikasikan bahwa variabel perilaku dan kontrol sikap tidak secara signifikan mempengaruhi penggunaan platform pembelajaran online. Secara kolektif, keempat variabel tersebut hanya menjelaskan 43,7% dari hasil perilaku, dengan 56,3% sisanya kemungkinan dipengaruhi oleh faktor-faktor lain di luar cakupan penelitian ini.

Abstract

Kondisi kadar hemoglobin dapat dipengaruhi oleh beberapa determinan yaitu konsumsi protein dan aktivitas fisik, terutama pada usia remaja yang masih membutuhkan berbagai macam zat gizi. Penelitian ini ingin membuktikan konsumsi protein dan aktivitas fisik sebagai determinan terhadap kondisi hemoglobin pada remaja. Penelitian ini merupakan penelitian observasional analitik dengan desain cross sectional. Total sampel dalam penelitian ini sebanyak 160 remaja di Kabupaten Sleman Yogyakarta dalam rentang usia 19-22 tahun yang diambil secara purposive sampling. Data dikumpulkan menggunakan kuesioner terstruktur dan pengambilan darah jadi, untuk mengetahui kadar hemoglobin menggunakan pengukuran Hb automatic. Konsumsi telur rebus dan sari kacang hijau mempunyai hubungan dengan kondisi hemoglobin yang baik (tidak anemia) pada remaja. Konsumsi telur rebus dan sari kacang hijau secara teratur baik untuk dilakukan, agar dapat memperbaiki kondisi kadar hemoglobin pada remaja.
