Abstract

The variety of six enzymes locus on three populations of Dioscorea bulbifera was revealed using both starch and polyacrilamide gel electrophoresis. Present study showed three polymorphic loci has each 2 alleles with nine total numbers of alleles for all populations examined. The higher alleles variety detected within population (Hs=0,08) than among population (Dst=0,04). The high levels of gene flow (0.53) were due to low differentiation among population. This result supported low levels genetic variation among population examined. Alozime data revealed moderate differentiation genetically between Western and Eastern part population from Bukit Barisan edge.

Abstract

Family Medicinal Plants (TOGA) are plants that can be used for health and are grown in the yard and managed by the family. These plants are grown to meet the needs of the family for medicines for prevention and daily treatment that can be self-processed. Apart from being a medicinal plant, the use of most of these plants also often doubles as a kitchen spice and ornamental plant. Community enthusiasm for the TOGA Park in Nagari Ambuang Kapua, Padang Pariaman District is quite high. From the survey, it was found that there are many large and empty yards of residents' houses in this Nagari. Meanwhile, in the TOGA Park itself, the diversity of medicinal plant species is very limited to certain species, especially those used for cooking spices only. Medicinal plants are sometimes replaced by the presence of ornamental plants. For TOGA to be utilized by the whole community, it is necessary to develop it through rearrangement and adding to the diversity of medicinal plant species. In the initial stage, planting is concentrated in one wider location. The activities were managed by the local community, especially PKK women who were accompanied by TOGA Activists and the Andalas University Team. It is hoped that the development/propagation of plants in a variety of species will create new TOGA gardens in every yard of residents' houses and be used by the community in the fields of health, aesthetics, and the economy. Family Medicinal Plants can provide benefits to society if cultivated in the right way. The activity was carried out by direct practice with the community at the park location accompanied by TOGA Activists with the Andalas University Team. This activity also received an award rating in the creative park competition at the local sub-district level in the Republic of Indonesia Anniversary competition.
Unraveling Genetic Relationship and Morphological Divergence of Rasbora tornieri (Ahl, 1922) across Sumatra Island: Genetic and Morphological Study of Rasbora tornieri Prawira, Furqan; Syaifullah; Tjong, Djong; Aadrean; Maideliza, Tesri; Roesma, Dewi

Abstract

Previous research indicates that the genetic diversity of Rasbora tornieri (Ahl, 1922) from the Musi River population in South Sumatra is notably low compared to populations from Borneo. Historical river connections between Sumatra and Borneo likely influence this low genetic diversity. However, the distribution of Rasbora tornieri across multiple geographic locations in Sumatra may contribute to significant genetic and morphological variations within this species. This study aims to elucidate the phylogenetic relationships and morphological variation of Rasbora tornieri across its known distribution in Sumatra. A comprehensive approach integrating molecular and morphological analyses was employed. Mitochondrial genes, Cytochrome c Oxidase subunit 1 (COI, 655 bp) and Cytochrome B (Cyt B, 629 bp), were sequenced, and morphological assessments were conducted. Phylogenetic and genetic diversity analyses revealed high genetic differentiation among populations. Morphological variations were statistically supported by the Mann-Whitney test, Principal Component Analysis (PCA), and Unweighted Pair Group Method with Arithmetic Mean (UPGMA) clustering, further highlighting population divergence. These findings indicate that geographic isolation and environmental factors influence the genetic and morphological diversity of Rasbora tornieri. Understanding these variations is crucial for conservation efforts, particularly amid habitat degradation and overfishing. This study provides valuable insights into freshwater fish biodiversity in Southeast Asia

Abstract

Limited understanding of rice cultivar biodiversity information in Solok Regency makes it difficult for people to determine which local rice originates from the area. This research aims to reveal the diversity and relationships of local rice, find specific morphological characters and their contribution value in providing diversity and find local rice candidates for plant breeding through analysis of potential superior characters. The method used is a field survey method with Principle Component Analysis (PCA) analysis to describe the contribution of a character in providing diversity and Cluster analysis to reveal the relationship between local rice cultivars. The 18 rice cultivars found included 11 local cultivars, 7 superior local cultivars. 3 of them from Solok Regency; Cisokan, Caredek, Siarang and the rest were released from various West Sumatra Agricultural Services. Based on the results of Cluster analysis and Principle Component Analysis, a dendogram was formed with 3 main clusters. Then we get morphological characters that have a contribution value with an eigen value> 0.3, including characters; plant height, leaf length, leaf width, ligule length, lower stem node diameter, flag leaf angle, leaf color, midrib color, flag leaf color, and center of panicle exit. This research also provides prospective local rice cultivars that have the opportunity to become superior local cultivars, such as; Padi Cinta, Situjuah, Sungkai and Talang Solok.

Abstract

Chlorophyll is a green pigment in plants which is important for the process of photosynthesis. The photosynthesis process affects plant growth. Seaweed extract has been proven to be a source of biostimulants that can increase plant growth, one of which is Padina minor. Concentration and frequency are important factors that influence the work of biostimulants. One effort to increase the effectiveness of biostimulants is by changing the crude extract into the form of nanoparticles. This research aims to analyze the effect of concentration, frequency, and interaction between concentration and frequency of crude extract and Padina minor nano extract on chlorophyll levels in soybean plants. The method used was a completely randomized design (CRD) in factorial consisting of 2 factors and 4 replications. Factor A concentration of Padina minor extract, namely control, crude extract 0.4%, nano extract 0.2%, 0.3%, 0.4%, 0.5% and 0.6%. Factor B is the frequency of administration of Padina minor extract, namely 1, 2, and 3 times administration. Based on research that has been carried out, the results showed that administration of 0.4% crude extract increased the average chlorophyll a level by 6.6% and a total of 11%. Meanwhile, chlorophyll b gave the same results as 0.3% nano extract, namely an increase of 14% compared to the control. The total frequency of administration of Padina minor extract was 3 times, and the same as the other treatments, increasing chlorophyll a levels by 4.6%, b by 5.2%, and a total of 4.9% compared to the control. The interaction between concentration and frequency of administration of Padina minor nano extract gives the same results as the crude extract, with lower concentration and less frequency of application in increasing levels of chlorophyll a, chlorophyll b, and total chlorophyll in soybean plants.

Abstract

The objectives of this study was to evaluate the utilization of plants, local wisdom and tribe attitudes about plant conservation by the people in Silokek National Geopark. This research used survey method. These data were collected by using Pebble Distribution Method (PDM) and Quisioner. And then, data had been calculated by calculating the value of Local User’s Value Index (LUVI). The result indicated that local people utilizing plants is for herbal medicine 83%. Cyclea barbata is spesies with having the highest LUVI (0.137), followed by Artocarpus elasticus used for furniture (LUVI= 0.060), Styrax sumatrana (LUVI= 0.126) used for ritual, and Imperata cylindrica (LUVI= 0.073) used for livestock feed. And The result showed at least three local wisdom that possible to be integrated to plant conservation such as planting the plants, selectively harvest by select cutting and timing, and special treatment before used the plants like shalawat nabi reading. For tribe attitudes indicated people in Silokek National Geopark more 90% agree for conservation policy in that area.Keywords : Local User’s Value Index (LUVI), Pebble Distribution Method (PDM), Silokek National Geopark.
