Abstract

Niyoghurt is yoghurt made from coconut milk. Coconut milk has a creamier, softer texture, and provides a distinctive taste compared to cow’s milk. Guava leaf contain a flavonoid compound, quercetin, which is antibacterial. This study aimed to evaluate the effect of the addition of guava leaf extract (Psidium guajava L.) to coconut milk yoghurt (niyoghurt) as a functional food. This study aimed to identify the water content, ash content, fat content, protein content, pH, total lactic acid, antioxidant activities, and hedonic color, flavor, taste, and texture from two types guava leaves (guava leaf and crystal guava leaf) and different concentration of extract (3%, 4%, and 5%). The results of the study showed that types of guava leaves had very significantly effects (P<0.01) on protein content, total lactic acid, hedonic color, texture and taste. The concentration of guava leaf extract had a very significantly effect (P<0.01) on fat content, protein content, total lactic acid, antioxidants, hedonic color, aroma, texture and taste, but did not have a significantly effect (P>0.05) on water content and ash content. The interaction between the type and concentration of guava leaf extract had a very significantly effect (P<0.01) on the hedonic color, texture, aroma and taste.

Abstract

Aklimatisasi merupakan fase krusial dalam perbanyakan anggrek secara in vitro karena menentukan keberhasilan adaptasi planlet terhadap kondisi ex vitro serta keberlanjutan pertumbuhan tanaman. Penelitian ini bertujuan untuk mengkaji pengaruh jenis media aklimatisasi dan jenis pupuk daun terhadap keberhasilan aklimatisasi dan pertumbuhan planlet anggrek Dendrobium lineale Blue. Penelitian menggunakan rancangan percobaan faktorial dengan dua faktor, yaitu media tanam yang terdiri atas sabut kelapa dan pakis, serta jenis pupuk daun Gandasil D (20:15:15) dan Growmore (32:10:10). Parameter pertumbuhan yang diamati meliputi panjang akar dan beberapa variabel pertumbuhan planlet selama masa aklimatisasi. Hasil penelitian menunjukkan bahwa penggunaan media tanam sabut kelapa menghasilkan panjang akar planlet Dendrobium lineale Blue yang lebih baik dibandingkan dengan media pakis. Keunggulan media sabut kelapa diduga berkaitan dengan kemampuannya dalam mengikat dan menyimpan air, memiliki porositas yang baik, serta menyediakan unsur hara esensial yang mendukung pertumbuhan dan perkembangan sistem perakaran. Sementara itu, pemberian pupuk daun Gandasil D (20:15:15) dan Growmore (32:10:10) menunjukkan pengaruh yang relatif sama terhadap pertumbuhan planlet selama aklimatisasi, yang ditunjukkan oleh tidak adanya perbedaan nyata pada seluruh variabel pengamatan. Hal ini mengindikasikan bahwa kebutuhan unsur hara planlet telah terpenuhi selama fase aklimatisasi. Hasil penelitian ini menegaskan pentingnya pemilihan media aklimatisasi yang tepat untuk meningkatkan keberhasilan adaptasi dan pertumbuhan
