Abstract

Abstract Pulchrana glandulosa is a frog from the family Ranidae which was described in 1882 by Boulenger with the Latin name Rana glandulosa. In his research, Boulenger described this species as having a size range of 48-83 mm in female individuals and 80-92 mm in male individuals. Meanwhile, in Das et al. as of 2007, this species measures 93 mm. The difference in size in the morphology of a species can be influenced by the environment where the species originates and the number of samples used also affects the size range obtained. For West Sumatra itself, research related to the morphology of P. glandulosa has never been done. Therefore, this study aims to provide the latest information on variations in the morphological characteristics of P. glandulosa in West Sumatra. The research method used is the Visual Encounter Survey/VES by exploring the research location from 20.00-23.00 WIB. The sample used was 12 individuals who were analyzed morphologically and morphometrically (18 characters), then compared with the holotype and paratype of P. glandulosa. The results of this study indicated that the P. glandulosa sample from West Sumatra was smaller than the P. glandulosa holotype; the length and width of the head in the sample, holotype and paratype are not much different; while the mouth length of the sample is larger than the holotype and paratype as well as the interorbital distance and the length of the first toe of the forelegs as a whole are still within the range that has been described. In other morphometric measurements, there are several individuals that are smaller than the holotype and paratype. And overall the measurement of the third and fifth toes of the hind legs is smaller than the holotype and paratype of P. glandulosa. Keywords: Morphological Study, Morphological Variation, Anura, Taxonomy, VES Abstrak Pulchrana glandulosa merupakan salah satu katak dari family Ranidae yang dideskripsikan pada tahun 1882 oleh Boulenger dengan nama latin Rana glandulosa. Dalam penelitiannya Boulenger mendeskripsikan spesies ini memiliki rentang ukuran 48-83 mm pada individu betina dan 80-92 mm pada individu jantan. Sedangkan pada penelitian Das et al. pada 2007, spesies ini memiliki ukuran 93 mm. Perbedaan ukuran pada morfologi suatu spesies tersebut dapat dipengaruhi oleh lingkungan dimana spesies itu berasal dan jumlah sampel yang digunakan juga berpengaruh terhadap rentang ukuran yang didapatkan. Untuk Sumatera Barat sendiri, penelitian terkait morfologi dari P. glandulosa belum pernah dilakukan. Oleh karena itu, penelitian ini bertujuan untuk memberikan informasi terbaru variasi karakteristik morfologi P. glandulosa di Sumatera Barat. Metode penelitian yang digunakan adalah Visual Encounter Survey/VES dengan melakukan penjelajahan pada lokasi penelitian mulai dari pukul 20.00-23.00 WIB. Sampel yang digunakan berjumlah 12 individu yang dianalisis secara morfologi dan morfometri (18 karakter), kemudian dibandingkan dengan holotype dan paratype P. glandulosa. Hasil dari penelitian ini menunjukkan bahwa sampel P. glandulosa dari Sumatera Barat berukuran lebih kecil dibandingkan holotype P. glandulosa; panjang dan lebar kepala pada sampel, holotype dan paratype tidak jauh berbeda; sedangkan panjang mulut sampel berukuran lebih besar dibandingkan holotype dan paratype serta jarak interorbital dan panjang jari pertama kaki depannya secara keseluruhan masih dalam rentang yang telah dideskripsikan. Pada pengukuran morfometri lainnya terdapat beberapa individu yang memiliki ukuran lebih kecil dibandingkan holotype dan paratype. Dan secara keseluruhan pada pengukuran jari ketiga dan kelima kaki belakang memiliki ukuran lebih kecil dibandingkan holotype dan paratype P. glandulosa.

Abstract

Fungus is one of the biodiversity that has an important role in human life which is widespread with a variety of habitat ranges. One of the biodiversity that has many benefits but is feared to experience a decrease in the number of species is mushrooms. In Indonesia, research on the diversity of macrofungi in residential areas is rarely reported. This results in minimal information on the types of fungi found in residential areas. Therefore, a study was carried out with the aim of knowing the diversity of macrofungi found in the Abi residential area, Lubuk Minturun Village. This research was conducted from September 2022 to May 2023 in the Abi Residential Area, Lubuk Minturun Village, Sungai Lareh, Koto Tangah District, Padang City, West Sumatra. The method used in this study is a direct survey in the field by exploring residential areas. Every mushroom found was immediately observed and its characteristics recorded, documented and preserved in a herbarium. Identification of fungi is carried out by adjusting the morphological characteristics with a reference book, namely the Collins Fungi Guide (2012) and with related journals. Based on the research that has been done, the macro mushrooms found are,Ganoderma lucidum, G. boninense, Daldinia concentrica, Plivatura crispa, Tyromyces sp., Tyromyces chioneus, Pycnoporus cinnabarinus, Gleophyllum sepiarium, Tramestes sp., T. versicolor, Auricularia sp., , Mycoacia uda, Psathyrella sp., Marasmius sp 1., Marasmius sp 2. All of these fungi are part of the phyla Basidiomycota and Ascomycota which are divided into 2 divisio, 5 ordo, 9 familia and 11 genera. Keywords: Abi Housing Complex , Diversity, Macro fungi Jamur merupakan salah satu biodiversitas yang memiliki peranan penting dalam kehidupan manusia yang tersebar luas dengan rentang habitat yang beragam. Salah satu biodiversitas yang memiliki banyak manfaat namun dikhawatirkan mengalami penurunan jumlah species adalah jamur.

Abstract

Forests are natural resources that play an important role in economic, social, cultural and ecological life. (Widodo & Sidik, 2020). One of the main environmental problems that arise is land damage due to deforestation and conversion of land to plantations (Akhmaddhian, 2016). Profile diagrams can be used to identify tree characteristics starting from height, crown density and width, tree architectural forms, and strata that are often used by wild animals in carrying out their daily activities (Nugraha, 2017). The purpose of this research is to learn how to make vertical and horizontal profile diagrams, to know the structure and stratification of forest vegetation in the Bukit Barisan I Protection Forest in the Lubuk Paraku sub-watershed, and to know how to cover the forest floor by the tree canopy. The research was conducted in November 2022-March 2023 in the Bukit Barisan I Protection Forest, Lubuk Paraku sub-watershed, Lubuk Kilangan District, Padang City. The method used is descriptive which begins with a field survey and then makes a single 60x20 meter plot at 2 observation stations. Then the collected data will be digitally described using the SeXI-FS application. The total number of trees in the natural forest is 37 trees of 6 different species, and in the forest adjacent to the parak 53 trees with 12 different species. The two locations are dominated by the species Villebrunea rubescens from the Urticaceae family. The structure of the vegetation at the two observation sites occupies stratum B and C, and the distribution pattern of the vegetation shows a random (uniform) distribution pattern. Thus, stratification, vegetation structure and forest floor cover structure are moderate.

Abstract

Shallots (Allium cepa L) is one type of superior vegetable that has long been cultivated by farmers. The demand and need for shallots that continue to increase every year is not in line with the amount of production each. The increase in crop production is often not balanced with an increase in fertilizer production resulting in fertilizer scarcity which results in crop. One solution that can be done is to use seaweed (Sargassum spp) which can be used as organic. This is because seaweed (Sargassum spp) contains important minerals needed by plants and can increase plant growth and crop The use of seaweed as fertilizer is expected to be an alternative solution to environmental problems because it is safe for soil microbes and Based on this, research has been conducted on the use of liquid fertilizer from seaweed (Sargassum spp) on the growth of shallots (Allium cepa).This study aims to determine the effect of applying liquid fertilizer from seaweed (Sargassum spp) with different concentrations on the growth of shallots (Allium cepa). This research was conducted from November 2022 to January 2023 at the Wire House of the Plant Physiology Laboratory of the Department of Biology, Faculty of Mathematics and Natural Sciences, Padang State This study used a Complete Randomized Design (RAL) with 4 treatments and 6 repeats. The treatment tested in this study was the concentration of liquid organic fertilizer from The data analyzed using ANOVA was followed by DMRT (Duncan's Multple Range Test) at a confidence level of 5%. The results showed that the application of liquid fertilizer from seaweed (Sargassum spp) with different concentrations affected the growth of heigh and dry weight of onion plants (Allium cepa), but did not affect the growth of the number of leaves and wet weight of onion plants (Allium cepa).
