Abstract

Penelitian tentang keanekaragaman reptil dilakukan untuk mempelajari jenis-jenis reptil apa saja yang menempati habitat Sungai Elo, Sungai Bengawan Solo, Kota Surakarta, dan Kabupaten Magetan. Penelitian ini dilaksanakan selama bulan Februari 2022 hingga bulan Maret 2022 dengan teknik Visual Encounter Survey (VES) atau teknik survei perjumpaan visual di empat lokasi pengamatan secara diurnal dan nokturnal. Total telah ditemukan 1 spesies dari Sungai Elo (Varanus salvator), 2 spesies dari Sungai Bengawan Solo (Varanus rudicollis dan Acrochordus granulatus), 2 spesies dari Kota Surakarta (Calotes versicolor dan Eutropis multifasciata)  dan 1 spesies dari Kabupaten Magetan (Lygosoma quadrupes). Hasil analisis diperoleh nilai indeks keanekaragaman Shannon-Wiener pada Sungai Elo dan Kabupaten Magetan sebesar 0; pada Sungai Bengawan Solo sebesar 0,4506; dan pada Kota Surakarta sebesar  0,6518 sehingga termasuk dalam kategori keanekaragaman yang rendah.

Abstract

Chloroplasts are double-membrane organelles that contain extranuclear DNA. The existence of this chloroplast genome (cpDNA) has an essential value for plant survival. This article will guide readers to comprehensively explore and answer questions about cpDNA, including the structure, function, mechanism expression, and inheritance, as well as the benefits of cpDNA. The method and analysis used are articles reviewed by searching, collecting, and analyzing related research articles. The main results obtained are the chloroplast genome in the form of a single quadripartite circular, its primary function for the synthesis of photosynthetic enzymes, and other functions as the biosynthesis of macromolecular compounds and secondary chloroplast metabolites, and plays a role in response to environmental stress, while the replication mechanism follows the maternal pattern in most Angiosperms and paternal in most Gymnosperms. The benefits of the chloroplast genome itself include the manufacture of recombinant pharmaceutical proteins, DNA barcoding, and Transplastomic. These results indicate that cpDNA has a crucial role in the survival of plants and humans. Further research and review regarding the relationship between environmental variables and the chloroplast genome are needed to complete the discussion on cpDNA.
