Abstract

Gelatin is a polypeptide obtained by partial hydrolysis of collagen derived from skin and bones of bovine and porcine. It has an essential component for the manufacture of gummy vitamin C as a gel-forming agent. The porcine gelatin is haram for moslems. This study was conducted to differentiate bovine gelatin and porcine gelatin in vitamin C gummy by using Fourier Transform Infrared (FTIR) combined with PCA. Gelatin was extracted from vitamin C gummy by using acetone at -20ÂșC and analyzed at wave number 4000-750 cm-1. The spectrum of both bovine and porcine gelatin extract from vitamin C gummy have almost the same number absorption that can not be distinguished. Therefore, the spectrum was analyzed by PCA. PCA result, represented with the plot score, showed that both bovine and porcine gelatin extracted has a clear dictinction. PCAcombined FTIR could differentiate of them. This study obtained that the commercial vitamin C gummy contained bovine gelatin.

Abstract

Antibiotik merupakan obat yang digunakan untuk mengatasi infeksi bakteri. penggunaan antibiotik di seluruh dunia telah meningkat sebanyak 36%, sehingga menyebabkan meningkatnya resistensi antibiotic. Untuk menghindari hal hal yang tidak di inginkan pada pengguanaan antibiotik, diperlukan KIE (Komunikasi, Informasi dan Edukasi). Proses KIE dalam Pengabdian ini menggunakan media Leaflet. Pengabdian ini bertujuan Untuk mengetahui Pengaruh KIE Media Leaflet Tentang Cara Penggunaan Amoxicillin Terhadap Pemahaman Pasien Rawat Jalan RSUD Dr. Harjono Ponorogo. Desain pengabdian ini adalah pemberian informasi kepada pasien dengan media leaflet, kemudian dilakukan perhitungan untuk melihat seberapa besar efektifitas dari pemveian informasi yang diberikan menggunakan metode kuantitatif deskriptif dengan studi Quasi eksperimental dengan menggunakan desain one group pre-test post-test. Sampel pada pengabdian ini berjumlah 70 responden yaitu pasien atau keluarga pasien. Pengabdian ini dilakukan pada bulan April-Mei 2024. Berdasarkan hasil Pengabdian Pengaruh Kie Media Leaflet Tentang Cara Penggunaan Amoxicillin Terhadap Pemahaman Pasien Rawat Jalan Rsud Dr. Harjono Ponorogo, menunjukkan bahwa nilai N-Gain diperoleh sebesar 0,81. Pada pengabdian ini dapat ditarik kesimpulan bahwa KIE dengan media Leaflet mempunyai pengaruh yang tinggi terhadap pemahaman pasien tentang cara penggunaan Antibiotik Amoxicillin.

Abstract

The results of the PISA study revealed that students have low critical thinking skills in Indonesia, especially in mathematics. This study aims to evaluate the effect of the Teaching at the Right Level (TaRL) strategy on the critical thinking skills of fourth-grade elementary school students in solving arithmetic problems in Yogyakarta. This study used a quantitative approach with a nonequivalent control group experimental design. The instruments used included essay tests, observation sheets, and documentation. Data were analyzed through descriptive statistics and t-tests to test the hypothesis. The results of the analysis showed that the TaRL strategy significantly improved students' critical thinking skills in four main aspects. The t-test produced a significance value of 0.000 (<0.05), indicating a significant difference between the experimental and control groups. The average posttest score of the experimental group reached 81.5, which is higher than that of the control group, which obtained an average of 76. This increase is illustrated in students' abilities to identify problems, analyze information, evaluate solutions, and logically convey arguments. These findings indicate that the TaRL strategy is effective in improving learning outcomes and contributes to strengthening students' critical thinking skills from an early age. Thus, the implementation of TaRL can be an alternative adaptive and transformative learning strategy to improve the quality of basic education in Indonesia.
