<![CDATA[Candida albicans and Malassezia furfur are types of fungi that often cause infections in humans. Widespread fungal infections and lack of therapeutic options can develop fungal resistance and become serious problems in the future. Actinomycetes are Gram-positive bacteria that can produce secondary metabolites such as antifungal, antibacterial, and anticancer. The study aimed to determine the effectiveness of the metabolite filtrate Actinomycetes as an antifungal agent against the in vitro growth of C.albicans and M. furfur. This type of research is a laboratory experimental study with a post-test group design only using metabolite concentrations Actinomycetes of 25%, 50%, 75%, 100%, antifungal testing is done using the agar diffusion method on Sabouraud Dextrose Agar Media. Of the four concentrations, the average diameter of the clear zone for C.albicans is 11.65mm; 12.48mm; 13.63mm and 13.80mm and for M.furfur is 6,025mm; 8,05mm; 9,1mm and 9,9mm. There was a significant difference between each treatment group with a p-value of < 0.05. The compound Metabolite filtrate Actinomycetes derived from Actinomycetes can potentially be antifungal with one of its mechanisms binding to ergosterol in the cell wall that will interfere with the integrity of the fungal cell wall.]]>

<![CDATA[This research is motivated by the low ability of students' tree thinking, the delivery of animalia material which is still abstract and learning method still teacher centered. So,this research used Modified Free Inquiry learning model which is student-oriented. This study aims to determine the implications of the Modified Free Inquiry learning model on the tree thinking skill of high school students in the Kingdom Animalia lesson. The type of research used in this research is Quasi Experiment with Non-Equivalent Control Group Design research design. The sampling technique used purposive sampling, which are class X MIPA 4 as the experimental class and X MIPA 6 as the control class. The results showed that the tree thinking skill of students in the Kingdom Animalia lesson resulted in an average pretest score of 37.84 and an average posttest score of 81.32 with an N-Gain average score of 0.74 in the high category. Based on the hypothesis test, the significance value of Sig (2-tailed) is 0.000, so H0 is rejected and H1 is accepted. The emergence of the experimental class students' tree thinking skill on each indicator varied but generally had an N-Gain score in the high category. The results of the student response questionnaire regarding the use of the Modified Free Inquiry model show an average score in the very good category (81-100), this is also in line with the teacher's response at the time of the interview. The results of the three instruments in this study indicate that the Modified Free Inquiry learning model has implications for the tree thinking skiil of high school students in the Kingdom Animalia lesson.]]>

<![CDATA[Phytoplankton is a source of food for zooplankton, fish larvae, and other organisms that live in seagrass beds. The purpose of this study was to determine the diversity of phytoplankton in seagrass beds in the coastal area of Mandalika, Central Lombok Regency. The location of water sample data collection was determined by purposive sampling by considering the percentage of seagrass cover. The sampling locations included 3 water locations, namely seagrass beds on the coast of Kuta, seagrass beds on the coast of Tanjung Ann, and seagrass beds on the coast of Gerupuk Bay. The research was conducted for three months from July to September 2021. The results of the study in the Mandalika coastal seagrass beds found 6 classes of phytoplankton, 26 orders, 30 families, 42 genera, and 46 phytoplankton species. Twenty one species of phytoplankton are from the Class Bacillariophyceae, 9 species from the Class Dinophyceae, 7 species from the Class Chlorophyceae, 5 species from the Class Cyanophyceae, 3 species from the Class Chrysophyceae, and 1 species from the Class Rhodophyceae. The abundance of phytoplankton at the three sampling locations ranged from 285-445 ind/L. The Phytoplankton Diversity Index in the three locations ranged from 1.35 to 2.75, which means communities with moderate diversity and dominance index ranged from 0.20-2.33.]]>

<![CDATA[The existence of Sansevieria sp. as an ornamental plant that has many benefits preserved. However, conventional propagation requires a lot of materials and time long. Leaf cuttings are only able to produce 1-2 plants in 2 months, and stop when they are aged 5 months. While the separation of tillers (Tillering) only produces 2-3 plants from 1 clump for 5 months. Tissue culture can be the solution, but sterilization must be done to minimize contamination without killing explants. The research aims to find out optimal concentration of HgCl2 and duration of shaking on the sterilization of Sansevieria leaf explants sp.. The research design used a completely randomized design with 2 factors. first factor namely the concentration of HgCl2 with 3 levels (4%, 7%, and 10%,) and the second factor is duration shuffled with 4 levels (3, 5, 7, and 9 minutes). Each treatment includes a negative control performed at the time of explant sterilization in Laminar Air Flow. Data analyzed by test ANOVA or Kruskal-Wallis. Followed by the 5% BNJ test if it is significantly different. Results show that the concentration of HgCl2 has a significant effect on the parameters of the initial time of contamination, the mass sterility of explants, and percentage of browning explants, but had no significant effect on percentage of contaminated explants. Concentration that is too high can slow down the appearance of contamination, prolonging the sterile period, but causing browning of explants. Known that the duration of explant shaking in HgCl2 had no significant effect on all parameter. The use of 10% HgCl2 with a shaking duration of 7 minutes (H3P3) is known to be the most effective optimal for sterilization of explants Sansevieria sp. because it is able to reduce external contamination, prolongs the sterile period up to 12.33 HST, and does not cause too many explants browning that is 33.33%.]]>

<![CDATA[This study aims to determine the distribution pattern and intensity of the attack of the corn cob and stem borer in Merauke Regency, Papua Province. This study uses purposive sampling method to determine the sampling by determining the specific characteristics that are in accordance with the research objectives, so that it is expected to determine the spread of insect pests. This research was conducted in 4 (four) villages in Semangga District and Tanah Miring District which have a lot of corn plants. One village was taken from each sub-district as the sampling location. Then each village is determined one location with an area of ± 0.5 ha. Sampling at each location used the diagonal slice method, so that in each location there were five sub-locations. Each sub-location 20 clumps were taken, and observations were made every 10 days on 42-day-old plants until harvest. Based on the results of the study, the highest percentage of attacks by Ostrinia furnacalis was in Semangga District in Semangga Village (6.71%), and the lowest was in Waninggap Say Village (3.13%). Meanwhile, the highest percentage of Helicoperva armigera attacks was in Isanombias Village (7.12%), and the lowest was in Muram Sari Village (3.12%). The low pest population is caused by farmers already using insecticides in pest control. The distribution pattern of Ostrinia furnacalis and Helicoperva armigera in Merauke Regency was random, where individuals spread out in several places and grouped together in other places, this was due to the homogenous environment of maize cultivation.]]>

<![CDATA[The main environmental problem today is still about pollution. Residential settlements always produce waste, especially household liquid waste. This type of waste is generally in the form of water that is cloudy in color and emits an unpleasant odor. This type of liquid waste is known as greywater. The direct impact of pollution is the contamination of groundwater (wells) and river water by greywater. As a result, the quality of the environment is getting disturbed. Especially in Angsau Village, Pelaihari Sub-district, Tanah Laut Regency, the majority of the population uses well water for bathing and washing toilets (MCK) and cooking. The purpose of this research is to reduce phosphate levels in greywater wastewater more effectively and efficiently. This type of research is a true experiment with a pretest-posttest research design with a control group design. The subject of the research was household liquid waste (greywater) which was taken at random in Angsau Village, Pelaihari District, Tanah Laut Regency, South Kalimantan Province. The study was designed with 6 treatments, namely variations of activated carbon used in two constructed wetlands reactor tanks. The first reactor uses coconut shell activated carbon, and the second reactor uses palm shell activated carbon. The results showed that, the thicker the activated carbon applied to the constructed wetlands reactor system, the lower the phosphate levels in household wastewater (greywater). The highest average percentage value was in the treatment with 15 cm thick activated carbon, and the lowest percentage mean value was in the treatment with 5 cm thick activated carbon. The results also showed that activated carbon from palm shells was more effective in reducing phosphate levels in household wastewater (greywater) compared to the use of activated carbon from coconut shells.]]>
