<![CDATA[The continuous use of chemical fertilizers will cause negative impacts such as pollution of the agricultural environment. This needs to be addressed by using Plant Growth Promoting Rhizobacteria (PGPR) which can trigger plant growth. Pseudomonas fluorescens is a bacterium that lives in the rhizosphere and is included in PGPR bacteria. P. fluorescens has the ability to produce siderophores, IAA, dissolve phosphate and fix nitrogen. Therefore, these bacteria can increase growth, provide plant nutrients and inhibit pathogens that cause plant diseases. This study aims to collect and analyze articles related to Pseudomonas fluorescens as PGPR. This type of research is research that uses the literature review method and literature collection using internet sources from the Google Scholar database. This stage consists of identification, screening, eligibility and acceptance. Based on the articles collected, it was found that P. fluorescens as PGPR can increase plant growth by having the ability to produce IAA, dissolve phosphate, produce siderophores and fix nitrogen.]]>

<![CDATA[Thermophilic bacteria are microbes that have the potential to produce heat-stable or thermostable enzymes ranging from 45-70 °C. So that thermophilic bacteria have a number of advantages in their use in the industrial sector which generally uses high temperatures. This study aims to examine the compatibility of thermophilic bacterial isolates. This research is descriptive using the pouring method (Pour Plate Method). The results showed that the thermophilic bacterial isolates tested (SSA- 8, SSA- 16, SSA- 14, SSA- 1, SSA-3 dan SSA- 12) and all their compatible partners were seen with no inhibition zones.]]>

<![CDATA[Biological control or biocontrol is a way that involves organisms to reduce the growth of pathogens and reduce the impact of disease. The use of biocontrol agents is an alternative to control plant disease-causing pathogens. One of the biocontrol agents that can be used is Pseudomonas fluorescens. Basically P. fluorescens is the largest group producing antibiotics and antimicrobial compounds of cyanide acid (HCN) and siderophores. The compounds it produces can inhibit activity and control pathogens. Therefore, P. fluorescens has great potential as a biocontrol agent for controlling plant diseases. This study aims to collect and analyze articles related to P. fluorescens as a biocontrol agent for controlling various plant diseases. This type of research is research that uses internet sources from the Google Scholar database. The stages consist of identification, screening, eligibility and acceptance. Based on the articles collected, it was found that P. fluorescens is a biocontrol agent that can control various plant diseases. Biocontrol agents influence the activity and growth of pathogens thanks to the compounds they produce]]>

<![CDATA[Water pollution is a deviation of the properties of water from normal conditions. Water that is polluted by pesticide residues when it has reached a certain concentration will greatly affect the environment and the aquatic organisms that live in it. Fish is one of the aquatic biota that can be used as an indicator of the level of pollution that occurs in the waters. Fish that have been contaminated with contaminants such as hazardous materials for a long time will experience changes in structure or function and will also experience changes in histological conditions. Therefore, any changes that occur in the aquatic environment will directly or indirectly affect the gills both structurally and functionally. This type of research is research that uses the literature review method. The stages of literature collection used in this study refer to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. This stage consists of four procedures, namely, identification, screening, eligibility and acceptance. This study shows that water pollution greatly affects the histopathology of fish gills because it can cause several disorders and diseases of fish gills. Key words : Water Pollution, Fish, histopathology of fish gills]]>

<![CDATA[Saponin merupakan salah satu senyawa metabolit sekunder yang terkandung dalam tanaman. Saponin tersebar luas pada seluruh organ tanaman diantaranya yaitu pada buah, biji, daun, umbi, batang, dan akar. Kandungan saponin lebih banyak ditemukan pada tanaman yang masih muda dari pada tanaman berumur tua. Metode yang digunakan yaitu studi literature. Ulasan ini bertujuan untuk memberikan gambaran mengenai efektivitas saponin sebagai antifungi. Saponin dapat diperoleh dari tanaman dengan metode ekstraksi. Metode ekstraksi merupakan sebuah proses pemisahaan berdasarkan perbedaan kelarutan bahan. Mekanisme kerja saponin sebagai antifungi yaitu dengan cara menurunkan membrane sterol sehingga mengakibatkan permeabilitas meningkat, lalu sel bengkak dan pecah sehingga mengakibatkan sel menjadi mati. Matinya sel tersebut mengakibatkan pertumbuhan dan perkembangan jamur menjadi terhambat. Dari beberapa penelitian telah terbukti bahwa saponin yang terdapat dalam tanaman terbukti memiliki aktivitas antifungi sehingga dapat dijadikan sebagai fungisida nabati.Kata Kunci: antifungi, tanaman, saponin, sel, jamur]]>

<![CDATA[Phosphate is very abundant in the soil, but only a small amount was dissolved. Some fungi have the ability to dissolve phosphates. This fungi is expected to overcome the excessive use of phosphate fertilizers. Those fungi ussualy found in soil or rhizorfere and sometimes they are endophytic. Rhizome of the simpei fern has endophytic fungi and its phosphate solubilizing activity was not known yet. This study aims to isolate endophytic fungi from rhizome of the simpei fern and to determine its phosphate solubilizing activity. Samples of simpei fern rhizome were taken from Nagari Aka Barayun, Harau District, Lima Puluh Kota District, West Sumatra. Surface sterilization using 0.5% NaOCL. The isolation medium for endophytic fungi used PDA medium and the phosphate solvent activity test used Pikovskaya medium. Six isolates of endophytic fungi were successfully isolated from the rhizome of the simpei fern and only three isolates were able to dissolve phosphate. The isolates are isolates R4, R5, and R6. Phosphate solubilizing activity of isolate R5 was higher than other isolates, although all isolates had a low phosphate solubility index.]]>

<![CDATA[The decline in the quality of agricultural products due to nutrient deficiencies such as phosphate is a major problem for agriculture in Indonesia. Technological advances have produced a way to overcome phosphate availability, namely by using phosphate-solubilizing fungi. Organic acids produced by phosphate-solubilizing fungi help reduce phosphate binding in the soil. This study aims to determine the activity of phosphate-solubilizing fungi isolated from Harau Valley Forest soil. Soil sampling was done by the purposive sampling method. The sampling area was along the Aka Barayun Forest in the Harau Valley. Isolation of fungi was carried out using the multilevel dilution method and poured on PDA medium. The fungus activity test was carried out using Pikovskaya media. Based on the results of the study, 6 isolates were obtained, 3 of which had phosphate solubilizing activity, as indicated by the formation of a clear zone around the fungal colonies. Fungal isolates were measured for colony zone diameter, clear zone diameter, and phosphate solubility index (IKF). The isolate with the highest activity was isolate T1, with an IKF of 1.0. The ability to dissolve phosphate of the fungal isolates obtained was categorized as low.]]>
