Abstract

Participants of the Chronic Disease Management Program (PROLANIS) at the Trosobo Health Center are a group of patients with diabetes mellitus and hypertension whose condition needs to be monitored regularly. Diet is one of the important factors that affect the stability of the health condition of patients in the Prolanis group. The purpose of this program is to provide education on healthy eating patterns for Prolanis participants. The method of activities carried out is counseling and workshops with a total of 30 patients. Counseling activities and workshops are carried out by involving families who care for patients. Evaluation of the success of the program is determined by the patient's level of understanding about healthy eating patterns and fasting blood sugar levels and the patient's blood pressure to normal and stable levels over time. Based on the results of the program evaluation that has been carried out, 90% of Prolanis patients understand about healthy eating patterns and apply them in their daily lives.

Abstract

Analysis of antibiotic residues in livestock products is challenging due to the low concentration of antibiotic residues and the complexity of the sample matrix. This study successfully used selective adsorbents from molecular imprinted polymer (MIP) materials for sample preparation. An adsorbent made of chitosan-based molecular imprinted polymer (Chi-MIP) was used to extract tetracycline residues from egg and milk samples. The adsorbent was made by preparing 0.1 grams of Chi-MIP in a 2x2 cm cellulose filter paper bag. Next, an adsorbent containing tetracycline was added to the sample. The extraction process was carried out using a hotplate stirrer. At the end of the extraction process, the extracted antibiotics are removed from the adsorbent through a desorption process in an organic solvent via an ultrasonicator. After that, the desorbed analytes were analyzed via a UV‒Vis spectrophotometer at a wavelength of 267 nm. To obtain optimum results, the extraction conditions were optimized to obtain the following results: extraction time of 12 minutes, desorption time of 3 minutes, and ethyl acetate as the desorbing organic solvent. Using the standard addition method, method validation results were obtained for each milk and egg sample matrix, which indicated a linearity range of 1–5mg/L, a correlation coefficient (R2) of 0.99, accuracy values ​​of 98.22% and 88.10%, precisions of 2.74% and 1.06%, LoDs of 0.4 mg/L and 0.51mg/L, LoQs of 1.52mg/L and 1.70mg/L, and enrichment factors of 3.27.

Abstract

Caffeine is a chemical compound that can be isolated from coffee beans. The isolation and purification of caffeine compounds have been successfully carried out using a filtration method using chitosan biomaterial synthesized by molecularly imprinted polymer (MIP). Chitosan as a functional polymer is dissolved in acetic acid (2% v/v) with stirring at 60°C overnight until a clear and homogeneous solution is formed. Furthermore, caffeine as a template molecule is added to the polymer solution and stirred for 60 minutes. The polymer solution is poured into a petri dish until evenly distributed and dried in an oven at 60°C for 12 hours. The dried polymer solution is then soaked in sodium tripolyphosphate as a crosslinking solution and dried again in the oven until the membrane sheet separates from the petri dish. The membrane sheet is then washed using distilled water until the pH is neutral and continued washing with chloroform to remove caffeine from the membrane pores to form an MIP membrane. The formed MIP membrane is characterized using FTIR and SEM. The MIP membrane was then cut into a circle, inserted into an empty syringe, and used to filter samples containing caffeine. The filtration results were analyzed using a UV-Vis spectrophotometer which showed that caffeine filtered with the MIP membrane contained less interference than caffeine filtered with a non-imprinted polymer membrane (NIP). Quantitative analysis was also carried out using the spiked sample method to determine the recovery value of the filtration results. From this study, the percentage recovery value (% recovery) was obtained at 96.16 - 103.80%.

Abstract

Escherichia coli merupakan bakteri yang mampu mendegradasi antibiotik golongan beta laktam generasi ketiga, keempat serta monobaktam. Bakteri E.coli penghasil ESBLs membuat pilihan antibiotik menjadi semakin terbatas untuk pengobatan sehingga bertanggungjawab terhadap peningkatan angka kesakitan, kematian, dan biaya kesehatan. Minyak lengkuas merupakan tanaman asli Indonesia yang terbukti mampu melawan bakteri patogen namun penelitian untuk bakteri penghasil ESBLs belum pernah dilaporkan. Minyak atsiri dalam bentuk nano mampu meningkatkan luas permukaan sehingga lebih efektif dan efisien untuk pengobatan. Penelitian ini bertujuan untuk mengetahui aktivitas nanoemulsi minyak lengkuas dalam menghambat bakteri E.coli penghasil ESBLs. Nanoemulsi dibuat dengan bantuan sonikator amplitudo 20% dan dikarakterisasi menggunakan Particle Size Analyzer (PSA). Nanoemulsi yang dibuat kemudian diujikan aktivitasnya pada E.coli penghasil ESBLs dengan spektofotometer panjang gelombang 600nm dengan seri pengenceran 0.35, 0.7, 1.4, 2.8, 5.6, 11.2, dan 22.5 μg/ml. Hasil penelitian menunjukkan bahwa Nanoemulsi dengan ukuran 490,3 mampu menghambat bakteri uji pada konsentrasi 0.7 μg/ml. dengan waktu inkubasi 24 jam dan 11.2 μg/ml.
