Abstract

Kelor (Moringa oleifera) dan Temulawak (Curcuma xanthorrhiza) merupakan jenis tumbuhan herbal yang dapat tumbuh pada iklim tropis seperti di Indonesia khususnya Nusa Tenggara Timur. Kelor dan rimpang temulawak sudah secara luas digunakan oleh masyarakat karena memiliki aktivitas farmakologi. Aktivitas yang dimiliki oleh kedua jenis tanaman ini disebabkan oleh kandungan kimia yang terdapat dalam masing-masing tanaman. Eksplorasi terhadap khasiat berbagai jenis tanaman terus dilakukan salah satunya adalah dengan mengkombinasikan ekstrak setiap tanaman. Pada peneltian ini dilakukan skrining fitokimia terhadap ekstrak kombinasi kulit batang kelor dan rimpang temulawak hasil maserasi menggunakan pelarut methanol. Perbandingan kombinasi ekstrak kombinasi adalah 1:1 dan perbandingan ekstrak dan pelarut adalah 1:6. Hasil uji menunjukkan bahwa ekstrak kombinasi kulit batang kelor dan rimpang temulawak positif mengandung kelompok senyawa alkaloid dan triterpenoid/steroid dan negated terhadao uji flavonoid, tanin dan saponin. Oleh karena itu pengujian lebih lanjut untuj menganalisis senyawa yang terkandung dan biaktivitas ekstrak kombinasi kulit batang kelor dan rimpang temulawak perlu dilakukan.

Abstract

This study aims to evaluate the validity of Student Worksheets (LKPD) in thermochemistry material designed using a Problem-Based Learning (PBL) approach, assess the implementation of learning using the PBL model, and examine students’ responses to the developed worksheets. The research employed the 4-D development model, although it was limited to the development stage only. The study involved 26 students from class XI.3 at SMA Negeri 1 Semau Selatan as the research subjects. Data collection methods included interviews, validation, and the distribution of questionnaires. The results of the study revealed that: (1) the developed Student Worksheets was considered highly valid, with average scores from material expert validators I and II at 93,05% and 98,6%, respectively, and from media expert validators I and II at 91,65% and 94,45%, respectively; (2) all aspects of classroom learning using the PBL model were implemented successfully; and (3) students’ responses to the LKPD were very positive, with an average score of 90%.
