Abstract

Ants are social insects that belong to the order Hymenoptera and the family Formicidae, besides that ants act as decomposers, pollinators, and soil aerators in shady places and moist soil under rotten wood and ants are the most dominant group of terrestrial animals in the tropics. This study aims to determine the diversity of Formicidae in the Sarasah Uwak waterfall area, Limau Manis, Padang City, West Sumatra, Indonesia. This research was conducted in November 2022 using the honey bait trap method. The results obtained in this study were 88 individuals with 20 genera belonging to 4 subfamilies namely the Dolichoderinae, Formicinae, Myrmicinae and Ponerinae families. Subfamily Myrmicinae is the family with the highest number of species with 4 species while subfamilies Dolichoderinae, Formicinae and Ponerinae have 1 species each. The species with the highest number of individuals is Odontomarchus sp. with 27 individuals and the least is Acanthomyrmex sp. with 2 individuals.

Abstract

Biofertilizer is a material that contains live microorganisms that are able to increase plant nutrition, one of which is Trichoderma. Trichoderma is able to have a positive influence on plants, plant growth and plant production results. Bran is a material that can be used as a growth medium for Trichoderma sp because it is able to increase nutrition in plants and is able to meet the needs needed for the growth and development of Trichoderma. The shelf life of bran is limited, therefore glycerol is added to the bran medium. This research is an experimental study using a Completely Randomized Design (CRD) with 6 treatments and 5 replications. The research was carried out by making a Trichoderma asperellum formulation using bran as the basic ingredient and adding glycerol at concentrations namely 0%, 20%, 40%, 60%, 80% and 100%. Data in the form of the number of spores at each concentration were analyzed using analysis of variance. The results of the research showed that for Trichoderma asperellum, giving different concentrations of glycerol in bran-based media did not affect the number of Trichoderma asperellum spores and shelf life because there was no real difference between the different concentrations given.

Abstract

Mangroves have two meanings, the first refers to plant communities or forests that are able to tolerate salinity or saltwater conditions (aquifers). While the second refers to individual plant species, mangrove species inventories are also important in a global context, given the role these ecosystems play in storing carbon and protecting coasts from storms and erosion. This study aims to inventory of mangrove species in Nagari Pilubang, Sungai Limau District, Sungai Limau Regency, West Sumatra. This study used the Spot Check method. The results of the inventory of mangrove species at the observation location showed that there were 17 species from 16 families that make up the mangrove forest observed. True mangroves include Sonneratia caseolaris, Nypa fruticans, Acrostichum aureum, Acanthus ebracteatus, Acanthus ilicifolius, while the following mangroves include Hibiscus tiliaceus, Derris trifolia, Dolichandrone spathacea, Pandanus tectorius, Cerbera manghas, Melastoma candidum, Ardisia elliptica, Glochidion littorale, Barringtonia asiatica, Calophyllum inophyllum, Morinda citrifolia, and Wedelia biflora.

Abstract

Birds are one species of animal that is greatly affected by forest land use change. Birds are known as good nest-making animals. The nest is made of twigs and lined with grass, moss, leaves or feathers. This research aims to determine the structure of artificial bird nests. In this study, 16 artificial bird nests were used, consisting of 2 types, namely type I with an entrance using steps and type II with an entrance using stairs/without steps. This research was carried out in November 2022 using observation and documentation methods. In this study, there were no birds occupying artificial nests, which could also be due to the fairly high level of campus activity. This can be due to several factors, namely, the construction materials used, design and placement of the structure, installation method, use of predator guards, as well as the condition of the nest which is moldy and mossy. Burung merupakan salah satu jenis satwa yang sangat terpengaruh akibat alih guna lahan hutan. Burung terkenal sebagai hewan pembuat sarang yang baik. Sarangnya ada terbuat dari ranting dan dilapisi rumput, lumut, dedaunan atau bulu. Penelitian ini bertujuan untuk mengetahui struktur sarang burung buatan. Pada penelitian ini menggunakan 16 sarang burung buatan yang terdiri dari 2 tipe yaitu tipe I dengan pintu masuk menggunakan pijakan dan tipe II pintu masuk menggunakan tangga/tanpa pijakan. Penelitian ini dilaksanakan pada bulan November 2022 dengan menggunakan metode observasi dan dokumentasi. Pada penelitian ini tidak terdapat adanya burung yang menempati sarang buatan juga dapat dikarenakan tingkat aktivitas kampus yang cukup tinggi. Hal ini dapat juga disebabkan beberapa faktor yaitu, bahan konstruksi yang digunakan, desain dan penempatan struktur, metode pemasangan, penggunaan penjaga predator, serta keadaan sarang yang sudah berjamur dan berlumut.

Abstract

Fluorescent pseudomonas are a group of rhizobacteria that colonize plant root areas and have potential as biocontrol agents for plant diseases that can be developed. This group of bacteria can increase plant growth by producing growth hormones, one of which is producing hormones Indole Acetic Acid (IAA), solubilizing phosphate, and siderophores. Apart from that, fluorescent pseudomonas are also able to induce plant resistance by producing secondary metabolite compounds which have antimicrobial properties. Many studies have shown that one of the most abundant microorganisms in the rhizosphere (around the roots) is bacteria Pseudomonas spp. This review will discuss the occurrence, distribution, growth studies, mechanisms of action, and control of plant diseases by fluorescent pseudomonad bacteria. This literature review will be helpful for future research aimed at providing information that fluorescent pseudomonads have potential as biocontrol agents for plant diseases.

Abstract

The use of biological control agents as alternatives to synthetic fungicides is increasingly being developed as farmers become more aware of the negative effects of synthetic fungicides. Various biocontrol agents have been developed from several bacteria that are very effective against plant diseases, including pseudomonas fluorescent. The mechanism of bacterial inhibition against pathogens can take place through several ways, namely colonization, competition and antibiosis. Pseudomonas fluorescent is able to produce secondary metabolite compounds such as siderophores, HCN, antibiotics, enzymes that can inhibit the growth and development of pathogens and can induce systemic resistance.
