Abstract

Research on the isolation of anacardic acid compounds from cashew nut shells has been carried out. This study aims to develop a method of isolating anacardic acid compounds from cashew nut shells in an easier way but still produces pure compounds. In this study, isolation and identification of anacardic acid compounds contained in CNSL were carried out. The results of anacardic acid isolation contained in CNSL form a thick brown extract with a characteristic dark odor. Anacardic acid was isolated using a maceration method using methanol as a solvent. The results of the isolation of anacardic acid compounds were then tested for purity using a thin layer chromatography test (TLC) using an eluent or a mobile phase of methanol: chloroform. Furthermore, anacardic acid compounds were identified using IR spectroscopy and UV-vis spectroscopy. This identification was carried out to prove that the compound obtained was indeed an anacardic acid compound. The identification results found that the compound isolated in this study was indeed an anacardic acid compound. It can be compared with the structure of existing anacardic acid compounds.

Abstract

Penelitian ini merupakan penelitian pengembangan (Research and Development) yang bertujuan untuk mengetahui: (1) langkah-langkah proses pengembangan modul praktikum kimia bahan alam berbasis generik sains tentang isolasi asam anakardat dari kulit biji jambu mete. (2) Tingkat validitas serta kepraktisan modul praktikum kimia bahan alam berbasis generik sains tentang isolasi asam anakardat dari kulit biji jambu mete yang sudah dikembangkan. Desain penelitian yang digunakan adalah model 4D (define, design, develop, and dissemination). Populasi dalam penelitian ini meliputi 80 orang mahasiswa program studi pendidikan kimia tahun akademik 2017/2018 yang sedang memprogramkan mata kuliah kimia bahan alam. Sampel penelitian yaitu tujuh mahasiswa yang diambil secara acak dan kemudian dijadikan responden untuk uji coba terbatas. Hasil penelitian menunjukkan nilai validitas dari tiga orang validator yang diperoleh menggunakan indeks Aiken adalah V = 0,6 yang menunjukkan bahwa modul praktikum praktikum kimia bahan alam berbasis generik sains tentang isolasi asam anakardat dari kulit biji jambu mete telah valid dan layak digunakan. Sementara itu, kepraktisan dapat dilihat dari respon mahasiswa dan dosen yang menunjukkan respon positif dengan rata-rata kepraktisan semua komponen sebesar 81% respon mahasiswa dan 81% respon dosen. Berdasarkan data tersebut dapat disimpulkan bahwa modul praktikum kimia bahan alam berbasis generik sains tentang isolasi asam anakardat dari kulit biji jambu mete yang dikembangkan bersifat valid dan sangat praktis digunakan dalam proses pembelajaran.  Kata kunci: Pengembangan, Modul Praktikum, Kimia Bahan Alam, Asam Anakardat
