Hyptis suaveolens (L.) Poit is one of the species Lamiaceae family (Labiatae), is an aromatic plant and can produce essential oils. Essential oils of these plants can be utilized as antimicrobials. The chemical components contained in the essential oils in the same plant may vary as they are influenced by several factors, including the growth stage. Essential oils can be obtained by hydrodestilation and their components are analyzed using gas chromatography-mass spectrometry (GC-MS). The essential oil components are then compared between those found in young leaves and adult leaves. The results of analysis and identification showed that in young leaves there are 50 components while in adult leaves there are only 37 components. The main components of young leaves were ?-caryophyllene (34.65%), germacrene-D (10.32%), ?-bergamotene (6.56%), ?-copaene (5.94%) and rimuene (6.46%), Are ?-caryophyllene (23.53%), germacrene-D (9.52%), ?-elemente (6.53%) and rimuene (13.19%). The components of ?-bergamotene and ?-copaene are not found in adult leaves.

Cassava (Manihot esculenta Crantz), which is commonly called singkong is multipurpose crop that can be processed as food, feed and other cassava-based bioproduct. Potential application of cassava starch is determined by the properties of starch as the main component of cassava tuber biomass. The size of the cassava starch granules is different for each variety due to genetic and the environment factors in which it grows. The size of the starch granules affects the application of the starch. This study aimed to determine the shape and diameter of the starch granule in several types of cassava through microscopic analysis. The shape and the size of the 62 starch samples tested was varied. The starch granules shape was dominated by spheres form. The diameter of cassava starch granules ranged from 2.016 ± 0.015 µm – 3.318 ± 0.045 µm. The highest diameter was Tidung1.2 and the lowest was Tidung 2.2.

Metabolit sekunder adalah senyawa-senyawa metabolik yang terdapat pada tanaman yang berperan dalam jangka waktu tertentu yang berfungsi menghasilkan sejumlah besar senyawa spesifik (kurang lebih 200.000 senyawa) yang memiliki peran berbeda-beda. Salah satu senyawa metabolit sekunder yang berfungsi sebagai pertahanan terhadap patogen (antifungi) adalah tanin. Tanin merupakan senyawa aktif metabolit sekunder golongan polifenol yang terdiri dari gugus hidroksi dan beberapa gugus terkait seperti karboksil yang dihasilkan oleh tanaman. Senyawa tanin memiliki aktivitas antifungi sehingga dapat memperkecil dinding sel jamur karena permeabilitasnya akan terganggu sehingga dinding sel jamur tersebut tidak dapat melakukan proses metabolisme sel.
