Abstract

ABSTRACTBackground: This research is an experimental study to determine the physical properties of propolis extract as an alternative material in pulpcapping treatment. High sorption value is the main cause of pulpcapping treatment failure. Purpose: to analyze the sorption value of propolis extract in water and artificial saliva. Materials and Methods: Thirty disc-shaped zinc oxide propolis (15 mm x 1 mm) specimens were stored in the incubator at 37ºC for 24 hours. The discs were weighed, dehydrated, and weighed again. Immediately after weighing, the discs were immersed for 1 day, 3 days, and 7 days in 50 mL of distilled water and artificial saliva at 37ºC and then weighed for second time (sorption value). Data were analyzed by one way ANOVA for data processing in the water and artificial saliva immersion group, then the Independent T-Test for inter-group immersion in water with artificial saliva. Results: There were differences in the sorption value of zinc oxide propolis with ZnOE (positive control) in water and artificial saliva between immersion times of 1 day, 3 days, and 7 days. There was no difference in the sorption value of zinc oxide propolis between the water and the artificial saliva immersion group. Conclusion: The sorption value of propolis extract, both in water and artificial saliva immersion shows a high sorption value. This indicates that the propolis extract has not met the criteria as a pulpcapping material in terms of its physical properties, namely absorption of water (water sorption).Keywords: Propolis extract, Pulpcapping, Sorption

Abstract

Abstrak. Penelitian ini bertujuan untuk mengembangkan LKPD berbasis KPS dan mengetahui persentase kelayakan, tanggapan guru kimia, tanggapan peserta didik, aktivitas peserta didik saat menggunakan LKPD berbasis KPS. Metode penelitian yang dilakukan adalah metode Research and Development (RD) dengan model pengembangan Analysis, Design, Develop, Implement, and Evaluate (ADDIE). Pemilihan sampel secara random sampling didapat 21 orang peserta didik kelas IX MIA2 dan 3 orang guru kimia. Instrumen yang digunakan berupa lembar penilaian para ahli, angket tanggapan guru, angket tanggapan peserta didik, dan lembar observasi aktivitas peserta didik. Hasil analisis data menunjukkan bahwa LKPD berbasis KPS telah memenuhi kriteria baik. Penilaian kualitas LKPD berbasis KPS oleh para ahli diperoleh persentase kelayakan sebesar 3,75 dengan kategori baik, tanggapan guru positif 89,8% dan 10,2% guru memberikan tanggapan negatif, sedangkan tanggapan peserta didik diperoleh masing-masing sebesar 31.899 (sangat baik), 34,758 (baik), 25,708 (cukup baik), 5,712 (kurang baik) dan 1,904 (tidak baik). Hal ini menunjukkan bahwa LKPD berbasis KPS yang telah dikembangkan sudah layak untuk diterapkan pada peserta didik di SMA/MA.Kata Kunci: Pengembangan LKPD, Keterampilan Proses Sains, Aktivitas, Peserta Didik, Koloid

Abstract

In the digital era, PT PLN launched the PLN Mobile application to enhance service efficiency for customers. This application facilitates customers in accessing information such as electricity bills, disturbance reports, and outage schedules without the need to visit PLN offices. This study aims to evaluate the utilization of the PLN Mobile application at PT PLN UP3 Pinrang, identify challenges faced, and formulate relevant solutions. The research method used is qualitative descriptive with an approach including interviews, observations, and documentation. The results of the study show that although the application provides convenience, challenges such as customers’ lack of understanding in using the application and technical issues remain obstacles. To address these issues, outreach and the provision of simple guides were conducted to improve customer understanding. Overall, the application has positively contributed to enhancing the quality of service and operational efficiency at PLN.
