Abstract

ABSTRACT Aracea is the latex herba that has spatha flower and spadik flower.  Generally, it lives wet area and most protect, there are some species of the plant live in dry area and exposed. Lembah anai preserve is some of nature conservation in West Sumatera. There is not researcher or reporter find out species of Aracea in Lembah anai preserve. The purpose of the research is to get information and description about species of Aracea   that find out in Lembah anai preserve regency Tanah Datar west Sumatera. This research starts in March until June 2013 by using direct survey method in the field, acquired data based on descriptive analysis. Based on this research got the result 34 species of Aracea that include 14 genus in lembah anai preserve kabupaten Tanah Datar west sumatera. The example of genus are Alocesia (1 spacies), Amydrium (1 species), Amorphophallus (1 species), Anadendrum (2 species ), Apobalis (1 species ), Arisaema (1 species), Caladium (2 species), Colocasia (1 species), Dieffenbanchia (1 species), Homalomena (2 species), Rhaphidophora (6 species), Schismatoglottis (4 species), Scindapsus (9 species) and Syngonium (1 species).

Abstract

ABSTRACT Many people ascription that rural area of its environment of cleanness and free from pollution, opinion like that not yet of course can be made by reference for interpreting about situation of environment of rural. This matter earn us see from more and more him consumer of motor vehicle and industrial factories able to generate problems which serious enough so that can bother flora productivity residing in around factory area. This research aim to to know types of lichenes ( crust moss) got in Nagari Batang Barus District Of Gunung Talang Sub Province of Solok. This Research type is descriptive research by using method of survey. Gathering of sampel and Record Keeping of type of lichenes ( crust moss) conducted by direct field. Result of obtained research in Jorong Kayu Jao Kenagarian Batang Barus District Of Gunung Talang Sub Province of Solok in finding 32 crust moss species namely 11 species with morphology type of foliose, 8  species  with  morphology type of  fruticosa,  13  species  with  morphology type  of crustuse. Of conducted research hence concluded that air around plantation of tea of PTP Nusantara VI Danau Kembar and of Jorong Kayu Jao Kenagarian Batang Barus District Of Gunung Talang Sub Province of Solok still cleanness, because of to the number of types of lichenes ( crust moss) found.

Abstract

Coleus scutellarioides is Labiatae. It have much varieties based on the leave shapes and colors. In the identification is not enough based on morpho-logical organ characters, but it can also based on the pollen morphology. The purpose of this study to determine the pollen morphology of seven varieties of Coleus scutellarioides. The research was conducted in the laboratory of Botany Department of Biology, State University of Padang, in April-May 2012. Seven varieties of Coleus used came from Padang Panjang and Lintau Buo. Pollen taken from bloomed flowers and it made be slides used acetolisis methods and 1% safranin staining method. Data were analyzed descriptively included pollen unit, polarity, symmetrically, size, shape, aperture, and the shape of pollen surface. The seven Coleus pollen varieties have similirity of the type of monad pollen unit, polarity isopolar type, radial symmetry, type colpate with 6 aperture located in the equatorial (Stephano), and reticulate surface-shaped pollen. Prolate spheroid shapes found in var. Eleanor, subprolate forms in var. Batique Fetish, var. Fack, var. Apricot, var. Burgundy Giant, var. Eleanor, and var. Flambe. Whereas prolate shapes found in var. Batique Fetish, var. Fack, and var. Va Va Boom. Pollen morphology of seven varieties of Coleus scutellarioides have different shape and the author have found 3 shape of pollen as the prolate spheroidal, subprolate and prolate.Key words: pollen, Coleus scutellarioides, identification

Abstract

Curriculum 2013 push student to have the high order thinking skills (HOTS). But in the SMPN 15 Padang especially in class VIII, there is no available teaching material that can improve students high order thinking skills in the learning process. Therefore, HOTS oriented LKPD has been developed in the structure and function of  plant tissue material. The purpose of this research to know validity of High Order Thinking Skills (HOTS) oriented student worksheet (LKPD) on structure and function of  plant tissue material for class VIII junior high school. This research is part of Plomp model that is development or prototyping phase. Data analyzed through quantitative analysis. The instrument of data collection using validation questionnaires. The product validated by 3 lecturers of biology and a natural science teacher of SMPN 15 Padang. Based on the results of the study obtained the validity of  LKPD 90.96%  with very valid category.

Abstract

The use of medicinal plant media is done to overcome Diabetes Mellitus which is expected to prevent complications, lower blood sugar and repair damaged cells in the body. Public knowledge about the use of medicinal plants has become a cultural heritage in Indonesia to date, such as in Nagari Manggopoh. This research was conducted in Nagari Manggopoh, Lubuk Basung Subdistrict, Agam Regency in December 2019 until January 2020. The method used is descriptive survey approach. The results found that in Nagari Manggopoh found 9 species of medicinal plants used to treat diabetes, which came from 8 families. The most commonly found plants are from the Asteraceae family of 2 species. Of the 9 species of 5 species have been cultivated in the homes of residents, and 3 species grow wild in the yard and in the forest.

Abstract

Mount Singgalang is one of the mountains in West Sumatra that is often climbed because it has natural beauty. Most climbers only have the determination and intention to make the climb and not understand the sciences in climbing. One part of survival is knowledge about wild plants that can be used for consumption and can also be used as medicine (herbal plants). This research was conducted to find out the types of plants that can be consumed on the Mount Singgalang hiking trail via Pandai Sikek. This research is a descriptive study using the survey method. The technique of collecting samples by inventorying samples in the field and continued identification and manufacture of herbariums at the Botanical Laboratory of FMIPA UNP. The data obtained is presented in the form of tables, where the plants are obtained at several elevation points, namely, 1670 masl, 1815 masl, 2137 masl, 2530 masl, 2667 masl. Based on the results of research conducted on Mount Singgalang, 9 species were found grouped into 6 families. Inventory of plant data can be grouped into several plants that can be consumed for food.Katakunci : Inventarisasi, Survival, Gunung Singgalang.

Abstract

Sweet potato varieties (Ipomoea batatas) Pucuk Hitam Panyalaian and Madu Pucuk Hitam Panyalaian have the potential to be a superior commodity in West Sumatra, but the information of genetic diversity is very limited. Data on the diversity of sweet potato germplasm is beneficial in the selection of plants to obtain superior cultivars in plant breeding. Aim: The aim of the study was to find specific primers for the study of sweet potato genetic markers using Ipomoea batatas chloroplast genes matK. Methods: DNA extraction from sweet potato young leaves; designing forward and reverse primers Ipomoea batatas chloroplast genes matK; PCR; sequencing; bioinformatics analysis and species identification by comparing the NCBI database. Results: Plant DNA barcoding PCR using designed primers matK were successfully resulting single DNA band in different amplicon size in some samples. This indicating that the designed primers used were able to distinguish variation in one species.
