Abstract

Zinc is a nutrient that affects cell growth, helps the body's metabolism, activates T cells (T lymphocytes), cell regeneration, and repairs body tissues. Zinc in the body undergoes a process of excretion every day, therefore daily intake of zinc needs to be considered to maintain the amount of zinc in the body in a normal amount. This study aimed to obtain information on the application of the Inductively coupled plasma-mass spectrometry (ICP-MS) method to determine the concentration of zinc in the serum of pregnant women. The application of Inductively coupled plasma-mass spectrometry (ICP-MS) method in zinc analysis provided the advantages of a minimal sample volume requirement with higher instrument sensitivity, fast retention time and had a concentration detection limit of up to parts per billion (ppb). Analysis of the zinc concentration in the serum of pregnant women using the ICP-MS method showed 80% serum with a concentration below the reference value, 13.3% normal and 6.7% a concentration higher than the WHO reference value.Keywords: defisiensi zink, inductively coupled plasma-mass spectrometry (icp-ms), zinkAplikasi Metode Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) Dalam Analisis ZinkABSTRAKZink adalah salah satu jenis zat gizi yang sangat berpengaruh terhadap pertumbuhan sel, mengaktifkan sel T (limfosit T), regenerasi sel, dan membantu metabolisme tubuh. Zink di dalam tubuh setiap harinya mengalami proses ekskresi oleh karena itu asupan harian zink perlu diperhatikan untuk menjaga jumlah zink di dalam tubuh tetap dalam jumlah yang normal. Penelitian ini bertujuan untuk mendapatkan informasi penggunaan metode Inductively coupled plasma-mass spectrometry (ICP-MS) untuk menentukan konsentrasi zink dalam serum ibu hamil. Penggunaan metode ICP-MS dalam analisis zink memberikan keuntungan berupa kebutuhan volume sampel minimal dengan sensitivitas alat lebih tinggi, waktu retensi yang cepat serta memiliki batas limit deteksi konsentrasi hingga bagian per triliun (ppt). Analisis konsentrasi zink dalam serum ibu hamil dengan metode ICP-MS menunjukan 80% serum dengan konsentrasi dibawah nilai rujukan, 13,3% normal dan 6,7% konsentrasi yang lebih tinggi dibandingkan nilai rujukan menurut WHO.Kata kunci : defisiensi zink, inductively coupled plasma-mass spectrometry (icp-ms), zink

Abstract. Problematic Financing Risk Problematic financing risk is a financing facility provided by a bank providing funds where the financing is in the category of substandard, doubtful or non-performing, resulting in the bank experiencing the risk that the financing cannot be returned or exceeds the specified time period. Factors that influence financing risk The problems are guarantees, financing procedures and customer behavior. Study of Sharia Banks in Bandung City. The method used in this research is a quantitative descriptive method. The sample in this research was 40 respondents. The sampling technique is non-probability sampling, purposive sampling type. The analysis used in this research is Likert scale analysis, validity and reliability testing and hypothesis testing is carried out using outer model and inner model tests. The results of this research show that the variables of financing procedures and customer behavior have a positive effect on the risk variable of financing problems. Meanwhile, the collateral variable does not have a positive effect on the problematic financing risk variable at the KC Bank Syariah Indonesia located in Bandung City. Abstrak. Resiko Pembiayaan Bermasalah resiko pembiayaan bermasalah merupakan fasilitas pembiayaan yang diberikan oleh bank penyedia dana dimana pembiayaannya dalam kategori kurang lancar, diragukan, atau macet sehingga mengakibatkan bank mengalami resiko pembiayaan tidak dapat kembali atau melebihi jangka waktu yang ditentukan. Faktor-faktor yang mempengaruhi resiko pembiayaan bermasalah ialah jaminan, lalu prosedur pembiayaan, dan perilaku nasabah. Studi pada Bank Syariah yang berada di Kota Bandung. Metode yang akan digunakan dalam penelitian ini yaitu metode deskriptif kuantitatif. Sampel dalam penelitian ini diperoleh sebanyak 40 orang responden. Teknik pengambilan sampel nya yaitu non probability sampling berjenis purposive sampling. Analisis yang digunakan dalam penelitian ini yaitu analisis skala likert, pengujian validitas dan reabilitas dan pengujian hipotesis dilakukan dengan menggunakan uji outer model dan inner model. Hasil penelitian ini menunjukkan bahwa variabel prosedur pembiayaan dan perilaku nasabah berpengaruh positif terhadap variabel resiko pembiayaan bermasalah. Sedangkan variabel jaminan tidak berpengaruh positif terhadap variabel resiko pembiayaan bermasalah pada KC Bank Syariah Indonesia yang berada di Kota Bandung.

Abstract

Obesity is a growing public health issue, particularly among young adults such as university students. Lifestyle changes characterized by high consumption of fast food and low levels of physical activity are major contributing factors to the increasing prevalence of obesity. This study aimed to examine the relationship between fast food consumption habits and physical activity levels with the incidence of obesity among students of the Pharmacy Study Program at Medistra Health Institute, Lubuk Pakam. This research employed an analytical observational design with a cross-sectional approach. The sample consisted of 59 students, selected using a simple random sampling technique. Data were collected using a Food Frequency Questionnaire (FFQ) to assess fast food consumption habits, physical activity questionnaires to determine activity levels, and waist circumference measurements as an indicator of central obesity. Data were analyzed using the Spearman rho correlation test with a significance level of p < 0.05. The results showed a significant relationship between fast food consumption habits (r = 0.596; p < 0.05) and physical activity (r = 0.389; p < 0.05) with obesity incidence among students. The findings indicate that students who frequently consume fast food and engage in low levels of physical activity are at a higher risk of developing obesity. In conclusion, unhealthy eating patterns and sedentary lifestyles are key factors contributing to obesity among young adults; therefore, preventive efforts through nutrition education and the promotion of regular physical activity are necessary within the university environment.
