Abstract

Kapalo Banda Taram Tourism Area, Lima Puluh Kota Regency is one of the tropical rain forest areas in West Sumatra which has a high level of biodiversity that can be disturbed due to the presence of invasive plants, one of which is Bellucia pentamera. The purpose of this study was to determine the distribution of B. pentamera, to determine the effect of the number of Bellucian on the number of non-Bellucian and to determine the effect of distance from the river and light intensity on the distribution of B. pentamera. The research using the belt transect with a plot size of 20x50 m2. Data analysis using the Morisita Index and Simple Linear Regression formulas. The distribution of B. pentamera was quite large with the distribution pattern of B. pentamera sapling strata is clustered, while the tree strata had a uniform distribution pattern. The number of Bellucian individuals affects the presence of non-Bellucian individuals as indicated by a negative effect on species diversity, a decrease in the number of species, high dominance and habitat colonization which will limit resources and space for the growth of other species. The distance from the river affects the distribution of B. pentamera where the closer the distance from the river tends to increase the presence of B. pentamera, while the light intensity does not affect the presence of B. pentamera.

Abstract

AbstractCats are domesticated animals whose existence is very close to humans. Maintenance of the wrong cat will cause the risk of zoonotic diseases. to humans caused by ectoparasites. Ectoparasites in cats are fleas, mites, and fleas. Information regarding the prevalence of ectoparsite infestation in cats can be used as a preventive measure. The purpose of this final report is to explain the prevalence of ectoparasites in cats at the Winadivet Animal Clinic in Malang. Prevalence sample examination was carried out on 156 cats divided into 7 breeds, namely Domestic, Persian, Bengal, British Short Hair, Peaknose, Anggora, Himalayan who came to the clinic during April 2021. Examination was carried out macroscopically and microscopically, microscopic method using native method. The results of the examination found 45 cats that were positively infected with ectoparasites, namely the Ctenocephalides felis flea, Felicola subrostatus fleas, Otodectes cynotis mites, and Sarcoptes scabei. The prevalence of infestation obtained was 28.8%. The highest prevalence of ectoparasites in purebred cats is in domestic cats with a prevalence value of Ctenocephalides felis 12.7%, Felicola Subrostatus 5.1%, Otodectes cynotis 3.2%, Sarcoptes scabei 0.6%. Factors that influence the high prevalence are environment, temperature, humidity, maintenance, and direct contact from infected animals.

Abstract

Fungi are one of Indonesia's potential natural resources which contain various benefits for human life. The existence of macroscopic fungi is not yet well known so that little information about the types and their benefits is known to local people. In fact, information about species of fungi is very important because fungi have economic value and are producers for the food and pharmaceutical sectors. Populations of macroscopic fungi can disappear due to climate change and environmental factors, therefore, it is necessary to collect data on the species of macroscopic fungi. One way to detect the species of fungus is to classify it based on the morphological characteristics of the fungus with K-Nearest Neighbor. The aim of this research is to explore and identify the morphological characteristics of fungi using K-Nearest Neighbor as a classifier found in the Bukit Selebu traditional forest area, Merangin Regency. It is hoped that the results of this research can be the first step in efforts to utilize fungi through further research. This research was carried out in the Bukit Selebu traditional forest area, Merangin Regency and identification continued at the Biology Laboratory of Merangin University. Then the data on the species of fungi found were analyzed using k-Nearest Neighbors (kNN). The results of this research are that there are 27 species of fungi found in the Bukit Selebu traditional forest area, Merangin Regency, consisting of 3 species of Ascomycota divisions and 24 species of Basidiomycota divisions. The K-Nearest Neighbor method is very good in classifying fungi through the extraction of morphological characteristics with the highest accuracy reaching 93%.

Abstract

One of the most biodiverse nations in the world, Indonesia is home to a wide variety of butterflies as well as other animals and plants. Butterflies play a significant role in the ecosystem, both in the pollination process and in the process of detecting environmental changes in the ecosystem. One alternate strategy for preserving biodiversity and natural resources while boosting a nation's economy is ecotourism. This study aims to investigate the perceptions and attitudes of local communities in West Sumatera regarding with butterflies and ecotourism. The study was conducted from February to March, 2023 by using two-page questionnaire developed to collect social information regarding with ecotourism and butterflies through in-depth interview with respondents who was currently living in West Sumatra. A total of 30 respondents (15 Male, 15 female) from various background were questioned. According to the survey’s findings, the majority of the population (93%) was passionate about protecting biodiversity and has extensive understanding of ecotourism and butterflies. Additionally, the majority of respondents (93%) mentioned that they would love to join Butterfly Watching Program. The respondents indicated that West Sumatera has a lot of ecotourism destinations. To draw visitors, a more sophisticated ecotourism program centered on beautiful wildlife and flora should be established.

Abstract

A total of 11 species belonging to 10 genera, 3 subfamilies with a total of 133 individual litter ants were collected at the Lembah Harau Nature Tourism Park. The results showed that the ecosystem of the Lembah Harau Natural Tourism Park tends to be stable. This is indicated by the index of ant diversity in the natural habitat of 0.98 which is low, while in the disturbed habitat it is 1.83, which is classified as moderate. as well as the dominance index in natural and disturbed habitats, namely 0.56 and 0.18 so that it can be concluded that no species dominates in these two habitats

Abstract

Lamiaceae is an important plant family that inhabits various ecosystems and has great diversity, is considered a cosmopolitan plant and has an important role in pharmaceutical and cosmetic sciences because of its essential oil content in almost every species. This research was focused on identify plant species from the Lamiacecae family that potential as essential oil producer in West Sumatra with their distribution based on ANDA Herbarium specimens. Data was collected use the herbarium method and literature study to determine the potential of each species. The results showed in the ANDA Herbarium were 45 species from 20 genera, which dominated by species that have the potential to produce essential oils as many as 23 species, followed by species that had not explore for their essential oil content as 11 species and commercial species,  9 species. Species from most Lamiaceae family were potentially as essential oil producer found in Padang city administrative area. Keywords: Cosmopolitan, genera, commercial, distribution, potential

Abstract

Harmful Algal Blooms (HABs) sering terjadi di kawasan pesisir laut. Sebaran spasial fitoplankton dapat menunjukkan area terjadinya HABs. Penelitian ini bertujuan untuk mengetahui sebaran spasial berdasarkan komposisi dan struktur fitoplankton penyebab Harmful Algal Blooms (HABs) pada perairan pesisir Kota Padang, Sumatera Barat. Penelitian ini menggunakan metode purposive random sampling dengan lokasi sampling sebanyak 6 lokasi (Muara Sungai Sungai Pisang, Muara Sungai Batang Arau, Muara Sungai Banda Bakali, Muara Sungai Batang Kuranji, Muara Sungai Batang Air Dingin, Muara Sungai Batang Kandis). Berdasarkan Penelitian didapatkan 338 spesies, 12 kelas, 85 famili fitoplankton dengan indeks keanekaragaman tergolong tinggi (H’= 3,026), penyebaran spesies merata (E = 0,520), serta tidak ada spesies yang dominan (C = 0,156). Dari semua lokasi penelitian ditemukan sebanyak 25 spesies fitoplankton berpotensi penyebab Harmful Algal Blooms (HABs) yang tergolong dalam 4 kelas (Bacillariophyceae, Chlorophyceae,Cyanophyceae, dan Dinophyceae) dan merupakan kelompok toxin producer dan red tide maker. Adapun spesies fitoplankton berpotensi penyebab HABs dengan kepadatan paling tinggi dan ditemukan pada setiap lokasi penelitian adalah Blixaea quinquecornis dan Trichodesmium erythraeum. Dengan demikian, perairan pesisir di Kota Padang berpotensi untuk terjadinya fenomena Harmful Algal Blooms (HABs).
