Abstract

Imunisasi merupakan tindakan preventif yang efektif dan murah untuk melindungi bayi dari penyakit menular. Namun, persepsi masyarakat mengenai imunisasi masih menjadi perbincangan. Penelitian ini bertujuan untuk menganalisis persepsi atau pandangan masyarakat mengenai pemberian imunisasi pada anak usia 12-36 bulan di wilayah tersebut. Penelitian ini menggunakan metode deskriptif dengan teknik pengumpulan data yang digunakan adalah wawancara dan dokumentasi, dengan tujuan memperoleh informasi mendalam mengenai faktor-faktor yang memengaruhi keputusan orang tua dalam memberikan imunisasi. Hasil penelitian menunjukkan perspektif masyarakat mengenai imunisasi masih tergolong negatif yang ditunjukkan dengan rendahnya ketercapaian imunisasi. Ketercapaian imunisasi dipengaruhi oleh berbagai faktor, termasuk kekhawatiran terhadap efek samping imunisasi, anggapan bahwa vaksin mengandung bahan tidak halal, serta kurangnya dukungan dari keluarga. Selain itu, informasi yang tidak akurat dari lingkungan sekitar dan media sosial turut mempengaruhi keputusan orang tua. Untuk meningkatkan cakupan imunisasi, diperlukan edukasi yang lebih intensif, keterlibatan tokoh masyarakat, serta peningkatan pelayanan kesehatan yang lebih ramah dan komunikatif.

Abstract

The low level of learning activities, analytical thinking skills, and student learning outcomes are indications of the need to improve the quality of learning through the implementation of innovative learning that makes students active subjects of learning in an effort to develop 21st century skills that are very important for students in facing the rapid development of science and technology today. This research aims to determine the effect of the PBL model assisted by student worksheets on learning activities, analytical thinking skills, and cognitive learning outcomes of class XI students at one of SMA Negeri in Medan City on the human immune system material. This material is very suitable for PBL because it contains complex biological processes and various disorders that involve the role of various components of the body. This research is a quasi-experimental research with a non-equivalent pretest-posttest control group design. Samples were obtained through class randomization until 2 classes were obtained, where 1 class was an experimental class and 1 class was a control class. The data obtained were analyzed using an independent sample t-test which showed a significance value lower than 0.05. Students in the experimental group showed higher learning activity (78,53 > 64,47), better analytical thinking skills (77,88 > 70,32), and higher cognitive learning outcomes (81,91 > 70,44) compared to the control class. Thus, it can be concluded that the PBL model assisted by student worksheets has a significant effect on learning activities, analytical thinking skills, and cognitive learning outcomes of class XI students.

Abstract

This study aimed to develop a Project-Based Learning (PjBL)-oriented practicum guide for basic molecular biology to enhance students’ concept mastery and science process skills in the IPAS subject, particularly on the topic of living organisms and their environment. The development model used was ADDIE (Analysis, Design, Development, Implementation, Evaluation). The research subjects were grade X students from the Health and Social Work Expertise Program at SMKS Galang Insan Mandiri Binjai. Data were collected through needs analysis questionnaires, expert validation sheets, student response questionnaires, and tests of cognitive understanding and science process skills. The practicum guide consisted of three core activities: simple DNA isolation, in silico PCR simulation, and basic electrophoresis, all designed in alignment with PjBL syntax. Expert validation results indicated a high level of feasibility: content expert (92.53%), instructional design expert (98.08%), and layout expert (94.81%). The guide’s effectiveness was evaluated through an independent sample t-test, showing significant differences between experimental and control groups in both concept mastery (t = 9.299; p = 0.000) and science process skills (t = 8.800; p = 0.000). These findings demonstrate the practicum guide's effectiveness in improving the quality of molecular biology instruction and fostering students’ ability to apply scientific processes in a contextual and collaborative manner. The study recommends adopting PjBL-based practicum guides as a relevant instructional strategy for vocational education in the 21st century.
