Get PDFThis study aims to determine the influence of brainstorming learning methods on the ability to think creatively in chemistry of grade XI science students. The type of research used is Quasi Experiment with a nonequivalent control group pretest-posttest design. The population of this study is all students of grade XI science for the 2022/2023 school year, totaling 158 students distributed in five classes. The sample used in this study was 60 students who were determined by cluster random sampling technique. Through random, class XI Science 4 was determined as a control class and in learning using conventional learning methods, namely lectures and discussions, and class XI Science 3 as an experimental class using brainstorming learning methods. Data on creative thinking skills were collected by test techniques using instruments in the form of description questions. The research hypothesis was tested using an independent t-test to analyze the difference between the n-gain of the control class and the experimental class using the help of SPSS 25 software. An independent t-hypothesis test yields a sig. (1-tailed) of 0.000 is less than the significance value (0.05). In the N-Gain test, experimental class N-Gain 0.6353 was obtained which was greater than that of control class 0.4255. Based on the t test and N-gain comparison, there is a positive and significant influence of brainstorming learning methods on students' creative thinking skills.Penelitian ini bertujuan untuk mengetahui pengaruh metode pembelajaran brainstorming terhadap kemampuan berpikir kreatif kimia peserta didik kelas XI IPA.

Identification of The Level of Pest and Disease Damage at The BPDASHL Indragiri Rokan Nursery, Pekanbaru, Riau
Get PDFPests and diseases are recurring issues in the cultivation of forest plant seedlings, as they can reduce seedling quality and lead to economic losses due to seedling mortality. Identifying the types of pests and diseases is crucial for implementing more effective, efficient, and environmentally friendly control measures to maintain seedling quality. The methodology used in this study was a field survey with direct observation of seedlings affected by pests and diseases. Data collected included the types of pests and diseases observed in various seedlings, such as Annona muricata, Albizia saman, Archidendron pauciflorum, Parkia speciosa, Nephelium lappaceum, Pometia pinnata, Persea americana, Durio zibethinus, Garcinia mangostana, and Artocarpus heterophyllus. Observations were conducted over an eight-week period. The damage caused by pests and diseases in the BPDASHL nursery was categorized as relatively mild. Common pests identified included beetles, borers, and mealybugs. Meanwhile, diseases frequently observed were yellowing leaves, sprout collapse, stunted growth, and leaf spot
Identification of Diversity and Genetic Distance of Indonesian Local Chicken Strains Based on Myostatin Gene
Get PDFIndonesian local chickens are essential genetic resources with significant potential for advancing the national poultry industry due to their high genetic diversity, reflecting adaptation to tropical environments and traditional farming systems. This study analyzed the genetic diversity of Kampung, Sentul, KUB, SenSi, and Broiler chickens based on the MSTN g.4842T>G locus. Blood samples from 150 chickens underwent PCR-RFLP analysis using the BsrI restriction enzyme targeting exon 2 of the MSTN gene. Parameters such as observed heterozygosity (Ho), expected heterozygosity (He), polymorphism information content (PIC), and Hardy-Weinberg equilibrium were assessed. Genetic distances were calculated using PHYLIP, and a dendrogram was constructed with UPGMA. The study identified two alleles (G and T) and three genotypes (GG, GT, TT), with the T allele being dominant, particularly in Broiler chickens (78.3%). Ho was lower than He in all populations, indicating a heterozygosity deficit. PIC values ranged from 0.282 (Broiler) to 0.367 (SenSi), classifying the MSTN locus as moderately polymorphic. Kampung and KUB chickens showed the closest genetic relationship, while Broiler chickens were the most distinct. These findings underscore the potential of local chickens in breeding programs for adaptability and productivity. Further research with additional markers is recommended to enhance sustainable poultry farming
Influence of Sargassum POC and Nano Bubble Technology on Hydroponic Pakcoy (Brassica rapa L.) Quality
Get PDFThe decline in vegetable production is caused by the conversion of agricultural land into residential areas which results in a reduction in agricultural land area. To overcome this problem, the hydroponic system is one of the alternative solutions used to replace lost agricultural land. The purpose of the study was to determine the effect of providing liquid organic fertilizer (POC) derived from (Sargassum sp.) with nano bubble technology on the quality of pakchoy (Brassica rapa L.) plants in hydroponic cultivation. The research method used a Completely Randomized Design (CRD) with five treatments. Data were analyzed using the ANOVA test and Duncan's test. The results showed that the P2 and P3 treatments were significantly different in increasing plant height with the highest average of 23.4 cm and the lowest P5 of 13.56 cm. Likewise, P3 produces the most optimal average number of leaves and overall plant quality, the cause is the availability of balanced nutrients. Nano bubble technology increases the efficiency of nutrient absorption and reduces sedimentation in the wick hydroponic system. The conclusion is that the combination of AB Mix and POC Nano is able to optimize the growth and quality of pakchoy plants in the hydroponic system, showing the potential for sustainable agriculture using innovative fertilizer technology

Utilization of Chicken Egg Shells as Adsorbents for Indigosol Blue Dyes with Variations of Activators
Get PDFThe textile industry still has serious problems in managing waste disposal that causes environmental pollution, including the batik factory industry. Many studies have been conducted to overcome ecological damage by reducing the levels of dyes contained in textile industry waste. Apart from textile industry waste, household waste, especially egg shells, is very high. One alternative method for processing batik factory liquid waste is by adsorption using biosorbent, which is considered cheaper and easier to obtain. An example of a biosorbent is an eggshell. This study includes the characterization of eggshells activated by NaOH and HCl for Indigosol Blue adsorption, morphological analysis of eggshells with SEM and EDS, wavelength determination, calibration curve, and adsorption capacity. The morphology of the eggshell shows a porous surface with high levels of calcium, oxygen, and carbon, indicating that the main compound forming the eggshell is CaCO3. The determination of maximum wavelength and adsorption capacity is done using the UV-Vis spectrophotometry method. The maximum wavelength is 530 nanometers, and an R2 value of 0.9596 was obtained from the regression curve equation. Characterization according to SNI eggshell before activation water content: 0.34%, ash content: 0.25%, iodine absorption: 326.552mg/gram and after activation with NaOH water content is 1.34%, ash content: 0.39%, iodine absorption: 403.015mg/gram. The optimal concentration of processed egg shells for indigosol blue adsorbent is 2% egg shells, the largest in this study as an adsorbent. It turns out that adsorption is still ongoing. The optimum type of activator for Indigosol Blue absorption is 100Mesh dry eggshell powder from NaOH activation
