<![CDATA[The Silokek Geopark area, Sijunjung Regency, is one of the tourist areas in West Sumatra Province which has a high level of biodiversity, which can be disrupted due to the presence of invasive plants. A study has been carried out which aims to determine the composition and structure of undergrowth in habitats invaded by weeds in the Silokek Geopark tourist area, Sijunjung Regency. This research was conducted from September to December 2022 using the quadratic method and plotting by purposive sampling with a plot size of 10 x 10 m with a sub-plot measuring 2 x 2 m. The composition of undergrowth in the habitat invaded by weeds found 24 families, 38 genera, 38 species, and 1049 individuals. Among the undergrowth found, there were 12 families, 20 genera, 20 species and 532 individuals of invasive plants with the dominant family being Asteraceae (30.41%), and the co-dominant family being Nephrolepidaceae and Poaceae with a percentage of 17 each. .83% and 11.63%. The highest important value index was in Nephrolepis biserrata (28.42%) and the lowest was in Musa acuminata (0.76%). The most dominant weed species was Mikania michranta with an IVI of 18.79%. The diversity index of the understorey plants in this area is categorized as high with a diversity index (H' = 3.24). Weed plant species are more successful in dominating open and disturbed areas with high levels of light intensity, gaps or wide gaps and forest edges can be utilized by invasive plant species to grow optimally.]]>

<![CDATA[Experimental research was carried out to obtain formulations of corn husk and sugarcane bagasse to produce good quality seed paper packaging. The differences in the raw material formulations used were (70% corn husk : 30% bagasse), P2 (50% corn husk : 50% bagasse) and P3 (30% corn husk : 70% bagasse). The research data were analyzed using ANOVA and for each treatment that was significantly different it was continued with the Duncan Multiple Range Test (DMRT) at the 5% confidence level. The results showed that corn husks and bagasse could be used as raw materials for paper, with a characteristic of yellow to brown in color, and were able to be formed into paper pouch packaging. Based on statistical analysis using ANOVA at α level of 5%, P3 treatment (25% corn husk : 75% bagasse) is the best treatment which produces paper packaging with the strongest tensile strength (12.1 N), the best elasticity (14.4%), as much as 65% can decompose in the soil after being planted for 4 weeks, and the seeds managed to germinate on the 9th day after the paper was planted.]]>

<![CDATA[Students' difficulty in understanding the learning material becomes a problem in achieving learning success. This is due to the lack of variety of learning models used by teachers, so far teachers have applied more cooperative learning models. Therefore, researchers try to apply the PBL (Problem Based Learning) learning model, which is one of the learning models that can stimulate students to think in problem-oriented situations. The purpose of this study was to determine the influence of the PBL model on students' problem-solving ability and cognitive learning outcomes. This research was conducted on grade 8th students of SMP Negeri 2 Kediri. This type of research is a pseudo-experiment (quasi-experimental). Data analysis using an independent sample t-test. The population in this study were all students from class 7th to class 9th. While the sample is students in grade 8th A as the experimental class and 8th B as the control class.The samples in this study were students of class 8th A as an experimental class and 8thB as a control class. The sampling technique uses purposive sampling technique. The results of the hypothesis test of problem-solving ability of experimental class and control class students obtained data that the sig < α was 0.009 < 0.05 at a significance rate of 5% so that H 0was rejected and H1 was accepted. In addition, on the results of the cognitive learning hypothesis test of experimental class and control class students, data were obtained that the sig < α was 0.003 < 0.05 at a significance rate of 5% so that H 0 was rejected and H1 was accepted. This shows that the PBL learning model affects students' problem-solving ability and cognitive learning outcomes.]]>

<![CDATA[Microplastics in the body of fish can damage the function of organs. One of the aquatic biota that can be affected by microplastics is Mutiara catfish. The study aimed to compare the gill morphology of Mutiara catfish after being exposed to microplastics. This study was an experimental study consisting of four treatments, feed treatment with microplastic added with a weight of 0.00 mg/0.75 g feed (control); 0.01 mg/ 0.75 g feed (P1); 0.1 mg/0.75 g (P2); and 1 mg/0.75 g (P3). Each treatment was repeated seven times (seven buckets) and each bucket was filled with five fish so that a total of 140 fish were used. The treatment was carried out for 28 days. Observation of growth parameters was carried out on the entire population, 140 fish, while organ preparation was carried out on a sample of three fish from each treatment. Fish samples were taken using a stratified random sampling technique. Research parameters include gill weight, primary lamela length (LP) and secondary lamela lenght (LS). The results showed the highest gill weight at control 1.76 ± 0.47 g and the lowest at P1 1.20 ± 0.25 g, although it did not significantly different. The highest gill weight/ body weight at control 0.06 ± 0.02 g and the lowest P1 and P2 0.04 ± 0.00 g, although it did not significantly different. Primary lamela length (LP) was highest at P3 1250.34 ± 294.81 μm and lowest at Control 894.78 ± 399.10 μm, and it was significantly different. Secondary lamela lenght (LS) was highest at P3 33.69 ± 4.34 μm and lowest at P1 29.12 ± 5.29 μm. Among controls, P2 and P3; LS length did not significantly different. Microplastic PE up to 1.00 mg/ 0.75 g of feed does not result in a decrease of gill weight and elongation of secondary lamela, but results in significant lengthening of primary lamela.]]>
