<![CDATA[Earthworms are invertebrate animals that live in the soil and are hermaphroditic. This animal requires organic materials as food. Research on the analysis of the growth of earthworms (Lumbricus rubellus) due to the addition of vegetable waste to feed has been carried out in Pagutan Village, Mataram City. This research aims to analyze (1) the effect of adding vegetable waste to feed on the number of earthworms, (2) the effect of adding vegetable waste to feed on the total weight of earthworms, (3) the best dose of vegetable waste so that earthworms can grow optimally. The earthworm growth parameters measured were the total number and total weight of earthworms at the end of maintenance. Research data was analyzed using analysis of variance. In this study it can be concluded: (1) adding vegetable waste (spinach, water kale, mustard greens and lettuce) to feed can increase the total number of earthworms, (2) adding vegetable waste to feed can increase the total weight of earthworms, (3) giving 2 liters of vegetable waste provided better growth results for earthworms compared to other treatments.]]>

<![CDATA[Research on Analysis of vegetative growth of mustard greens (Brassica juncea L) due to vermicompost and urea fertilizer treatment was carried out from April to July 2024 In West Lombok. This research aims to analyze: 1) vegetative growth of green mustard after urea fertilizer treatment, 2) vegetative growth of mustard greens after vermicompost treatment 3) the interaction effect of vermicompost and urea fertilizer treatment on the growth of green mustard. In the research a 2 factor design was used. Growth parameters of mustard greens measured were plant fresh weight, stem height, number of leaves and length of mustard green leaves. Data from measurements of all the growth parameters above were analyzed using analysis of variance. The results of the mustard green growth analysis showed that: (1) urea fertilizer treatment had a significant effect on fresh weight, plant height, number of leaves and leaf length of mustard greens, (2) vermicompost treatment had a significant effect on all mustard green growth parameters. (3) the interaction between urea and vermicompost fertilizer treatments did not have a real effect on the growth of mustard greens.]]>

<![CDATA[Earthworms (Lumbricus rubellus) belong to the phylum Annelida, class Clitellata, order Haplotaxida, family Lumbricidae, and genus Lumbricus. They thrive in loose and moist soil habitats. This species is commonly used as animal feed due to its high protein content, which is 65% higher than that of mammalian meat and 50% more than that of fish. To meet the increasing demand for earthworms as livestock and fish feed, their cultivation and production need to be enhanced. One method to boost earthworm production is by manipulating their reproduction through superovulation using Pregnant Mare Serum Gonadotrophin (PMSG). PMSG is a hormone produced by the chorionic cups of pregnant mares and has biological effects similar to Follicle-Stimulating Hormone (FSH) and minor Luteinizing Hormone (LH) activity. This study used a completely randomized design consisting of four groups: the control group (K0) without PMSG treatment, treatment group 1 (K1) receiving 200 IU PMSG dissolved in 100 ml of distilled water, treatment group 2 (K2) receiving 250 IU PMSG dissolved in 100 ml of distilled water, and treatment group 3 (K3) receiving 300 IU PMSG dissolved in 100 ml of distilled water. The treatment was applied by immersing the earthworms in the solution for 2 minutes. Each treatment group contained 10 earthworms and was replicated 10 times. Data were analyzed using one-way ANOVA at a 5% significance level, followed by the Least Significant Difference (LSD) test. The results of this study indicate that the administration of Pregnant Mare Serum Gonadotrophin for superovulation significantly increases cocoon production in Lumbricus rubellus.]]>

<![CDATA[Cabbage (Brassica oleracea) is one of the vegetable wastes that is often produced by the Amahami market, Bima City. With its easy-to-wilt nature and high water content, cabbage causes it to rot quickly, which will impact environmental problems. Processing market waste certainly requires sustainable management. One model of waste management is to use it as feed. This research aims to determine the effect of giving cabbage waste on the increase in the population of earthworms (Eudrilus eugeniae). The research was carried out in Bima City, Ule Village, Asakota District, Tolotongga Environment. The type of this research is experimental. The research design was a Completely Randomized Design (CRD) with four treatments and ten replications. The parameter observed was the increase in the number of earthworms, analyzed using One Way Anova and followed by Duncan's Multiple Range Test (DMRT). The results of the research showed that giving cabbage waste (Brassica oleracea) as feed had a significant effect (0.009<0.05) on increasing the population of earthworms (Eudrilus eugeniae). The treatment with the highest results was P1 (50 grams of cabbage), with an average number of worms of 367.30.]]>

<![CDATA[Facing the challenges of the 21st century, learning must be able to produce learners into creative individuals to solve problems. The ability to think creatively is closely related to a person's character or creative habits; good character can trigger good skills. This study aims to determine how applying the Contextual Teaching and Learning (CTL) model improves students' creative disposition and creative thinking skills. The method in the form of Quasi-Experimental Design uses Pre-test and post-test control Group Design on as many as 64 X students at one of Aikmel State High Schools, NTB. The 32-person experimental class used the CTL model of the guided inquiry method, and the 32-person control class of the discussion method. Data on students' creative dispositions were collected using creative disposition questionnaires given before and after good treatment in both groups. Data on students' creative thinking skills were collected with a creative thinking skills test developed referring to the Torrance Creative test. The data were obtained and analyzed using the t-test to determine the comparison of the two classes and the N-gain test to see the improvement in each class. The results showed significant differences in creative disposition and creative thinking skills between the experimental class and the control class. Increased creative disposition in the experimental class with an N-gain of 0.45 means an increase in the medium category and an N-gain of 0.08 in the control class, which means an increase in the low category. Meanwhile, the creative thinking skills of experimental class students amounted to an N-gain of 0.48, which means there was an increase in the medium category, and an N-gain of 0.05 in the control class, which means there was an increase in low theory. This study concludes that applying the CTL model can improve creative disposition and thinking skills.]]>

<![CDATA[Basic teaching skills are skills that prospective teacher students must have. This research aims to determine the level of basic teaching skills in teaching practice among Biology Education students taking the Micro Teaching course in class A group B in 2022/2023. Data was collected from observations of student teaching practices through peer teaching. The instrument used is an observation sheet derived from indicators of eight aspects of basic teaching skills, with answer choices using a Likert scale. The data was analyzed descriptively by calculating the average score obtained by each indicator on the eight aspects of basic teaching skills observed. The observation results show that students' average in all aspects of basic teaching skills is very good. In contrast, the results of observations on the indicators for each element of skills show categories that vary from quite good, good, and very good. It can be concluded that students have been able to apply the eight aspects of basic teaching skills in teaching practice very well. However, if we look at the indicators for each aspect of skills, there are still students in the quite good and good categories.]]>
