Abstract

Latar belakang : Sediaan tabir surya dapat digunakan untuk menyerap sinar matahari secara efektif terutama pada daerah emisi gelombang UV. Kondisi stress saat penyimpanan suatu sediaan dapat mempengaruhi sifat fisik dan kimiawi. Penelitian ini bertujuan untuk menentukan pengaruh kondisi stress penyimpanan terhadap stabilitas fisik dan nilai Sun Protection Factor (SPF) sebagai efektivitas dari sediaan tabir surya yang disimpan dalam tiga suhu berbeda. Metode : Penelitian eksperimental ini dilakukan dengan pemilihan sampel tabir surya dan pengujian stabilitas fisik meliputi pengamatan warna, pengamatan fisik, uji pH, uji daya sebar, uji daya lekat, serta pengukuran nilai SPF sediaan tabir surya lotion dan gel dengan spektrofotometri yang disimpan pada suhu ruang (25◦C), suhu rendah (4◦C), dan suhu tinggi (40◦C). Hasil : kondisi stress penyimpanan mempengaruhi sifat fisik sediaan berupa daya lekat, daya sebar, dan mempengaruhi secara signifikan nilai SPF sediaan (p<0,05) mulai hari ke-14 penyimpanan.

Abstract

This research is motivated by the problem of the religious character of students which is increasingly concerning and needs the attention of all parties, including educational institutions. The importance of character education requires PAI teachers to pay more attention to strengthening the religious character of students in schools, including students in class XI TITL 1 (Electrical Installation Engineering) at SMK N 1 Koto Balingka. The purpose of this study was to determine the implementation of Islamic Religious Education learning materials in strengthening the religious character of class XI TITL 1 students at SMKN 1 Koto Balingka, West Pasaman Regency and to determine the supporting factors and inhibiting factors for the implementation of Islamic Religious Education learning materials in strengthening the Religious Character of students in class XI TITL 1 At SMKN 1 Koto Balingka. This research uses a qualitative descriptive approach with a case study type of research. This research collects data by observation, interviews and documentation. Data analysis starts from data reduction, data presentation, and drawing conclusions. The results showed that the implementation of Islamic religious education learning materials in strengthening the religious character of class XI TITL 1 students at SMKN 1 Koto Balingka Pasaman Barat, namely through in-curricular activities and through extra-curricular activities. Supporting factors and inhibiting factors for the implementation of Islamic Religious Education learning materials in strengthening the religious character of class XI TITL 1 students at SMKN 1 Koto Balingka, West Pasaman district, are adequate libraries, classrooms and the presence of the Koran. The inhibiting factors are the students themselves who lack awareness in implementing religious activities at school, the backgrounds of students who differ in terms of religious understanding, the environment or student associations which tend to be less relevant to the process of strengthening students' religious character and inadequate places of worship.
