Abstract

Plants are an important source of natural medicinal compounds, particularly through secondary metabolites with biological activity. Avocado leaves (Persea americana) and belimbing wuluh leaves (Averrhoa bilimbi) are known to contain such compounds and hold potential as natural medicines. This study aims to identify the secondary metabolite content in combined extracts of avocado and belimbing wuluh leaves through phytochemical testing. The method used was qualitative phytochemical analysis to detect the presence of active compounds in each extract and in their combination. The results show that avocado leaf extract contains flavonoids, phenols, alkaloids, saponins, and steroids, while belimbing wuluh leaf extract contains phenols, flavonoids, alkaloids, and steroids but lacks saponins. After combining the two extracts, the test results indicated the presence of flavonoids and phenols. These findings suggest that the combined extracts retain key bioactive compounds with potential pharmacological effects. The study concludes that the combination of avocado and belimbing wuluh leaf extracts contains secondary metabolites that may be further developed as natural medicinal ingredients. The implications open opportunities for future research to examine the pharmacological activity and therapeutic potential of this plant extract combination.

Abstract

Pembelajaran dengan model pendekatan STEAM, yang diintegrasikan dengan model pembelajaran PjBL, diharapkan mampu meningkatkan kemampuan berfikir kritis peserta didik dalam belajar. Jenis penelitian yang digunakan adalah penelitian dan pengembangan atau R&D (Research and Development) dengan model 4-D, yaitu penelitian yang menghasilkan produk tertentu. Model 4-D terdiri dari empat tahapan.Penelitian ini dibatasi sampai tahap pengembangan dengan uji validitas dan praktikalitas. Teknik pengumpulan data yang dilakukan dengan cara penyebaran angket dan analisis data hasil penelitian validitas menggunakan Aiken’s V. Berdasarkan hasil analisis angket validitas LKPD diperoleh nilai V yaitu 0.89 dengan kategori sangat tinggi dan hasil praktikalitas dari respon guru dan peserta didik berturut-turut yaitu 84.8% kategori sangat tinggi dan 82.3% kategori sangat tinggi. Dapat disimpulkan bahwa, LKPD Sel Volta terintegrasi STEAM-PjBL yang dihasilkan telah valid dan praktis, sehingga dapat dinyatakan layak untuk digunakan dalam proses pembelajaran.

Abstract

Stunting is a chronic malnutrition problem caused by inadequate nutritional intake over a long period of time, resulting in impaired optimal physical and cognitive development. The problem of stunting and malnutrition requires coordination between various parties to overcome it. In Agam Regency, especially Nagari Kamang Hilia, the stunting rate is still relatively high, with a prevalence of 24.6%, according to the latest Indonesian Nutrition Status Survey (SSGI). One of the factors influencing this is the high cost of nutritious food, which reduces the interest of mothers in serving healthy menus for the family. Therefore, education and training on nutritious food processing with alternative food sources is needed to increase public understanding. This program targets posyandu cadres and PKK mothers as the main targets, with the aim of providing knowledge about the importance of fulfilling nutrition to prevent stunting and malnutrition. The results of this activity are expected to increase awareness and interest of mothers in processing nutritious food that is attractive and liked by families, especially children.
