Abstract

Cervical cancer is one of the main problems of reproductive health in women in Indonesia. The results of a questionnaire of 100 women of productive age workers in UNP 80% had never done an IVA test and did not know about the IVA test for early detection of cervical cancer. Lack of knowledge and awareness of women workers at UNP to take preventive measures for early detection of cervical cancer, is carried out in prevention of cervical cancer with seminar and IVA test for productive ages women in Universitas Negeri Padang. Activities have been carried out in the rector's office, faculties and IVA test at the UNP polyclinic in collaboration with the Air Tawar Health Center, Padang City Health Office and the UNP Polyclinic. This activity has 3 stages namely seminar the importance of early detection of cervical cancer, IVA test and monitoring. Participants are women of childbearing age over the age of 18 who are married / widowed, not yet married but have had sexual intercourse at UNP. Seminar participants totaling 130 participants have exceeded the 30% target. Monitoring activities are carried out with questionnaires to participants through a Google form sent to participant WhatsApp. The questionnaire contained aspects of knowledge and attitudes of participants towards early detection of cervical cancer. The results obtained 88.40% knowledge aspects (very good) and 84.16% attitude (good). But the participation for IVA test is still less than 10%. With this activity increased knowledge and active role of women for preventive action with early detection of cervical cancer that aims to improve the quality of health and reduce the mortality rate of Indonesian women against cervical cancer.

Abstract

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.

Abstract

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.

Abstract

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.
