The use of banana peel as feed to increase growth of earthworms (Lumbricus rubellus)

Research on using banana peels as feed to increase the growth of Lumbricus rubellus has been carried out. This study aims to determine: (1) the effect of different doses of banana peel pulp on feed on the growth of earthworms (Lumbricus rubellus), (2) the best dose of banana peel pulp to increase the growth of earthworms. This research is a one-factor study. The research was carried out with five levels of treatment and five replications. The doses of banana peel pulp are 0 ml, 250 ml, 500 ml, 750 ml, and 1000 ml. The parameters of the growth of earthworms measured were the addition of the number of individuals and the addition of the weight of the earthworm population. The research data were analyzed by analysis of variance. The research results show that: (1) the difference in the dose of banana peel pulp significantly affected the increase in the number of individuals and the weight of the earthworm population; (2) the addition of 1000 ml of banana peel pulp resulted in the highest number of individuals and the heaviest population weight compared to other treatment doses

Analysis of Purple Eggplant Growth After Vermicompost and NPK Fertilizer Treatment

Eggplant growth rate is determined by genetic and environmental factors. Environmental factors that affect eggplant growth include the availability of nutrients on agricultural land. Research on analysis of purple eggplant growth after vermicompost and NPK fertilizer treatment was carried out from March to July 2023. This study aims to analyze the effect of the application of vermicompost on the growth of purple eggplant. The application of NPK fertilizer on the growth of purple eggplant. The interaction effect of vermicompost and NPK fertilizer treatment on purple eggplant growth. Growth parameter data were analyzed using the F test. The results showed that: Vermicompost application increased stem height, total leaves and leaf length but did not increase leaf width and stem diameter of purple eggplant. The application of NPK fertilizer was effective in increasing stem height, total leaves, leaf length, leaf width and stem diameter of purple eggplant. The interaction of vermicompost treatment and NPK fertilizer was not effective in increasing all measured growth parameters

The Effect of Project-Based Learning with the Science, Technology, and Society Approach on Digestive System Material Against the Concept Mastery

This study aims to examine the effect of a project-based learning model with a science, technology, and society approach to students' mastery of class VIII concepts. This type of research is a quasi-experimental type using a non-equivalent control group design. The population of the study was students of SMP Negeri 7 Mataram for the 2021/2022 academic year with a sample consisting of 74 class VIII students. The data obtained were analyzed using the Covariate Analysis test (anacova) with reference to a significance level of 0.05. The results of the study show that the sig. (p) = 0.000 less than alpha 0.05, so it can be concluded that the project-based learning model with a science and technology community approach has a significant effect on junior high school students' conceptual understanding

Pengaruh Daun Kopasanda (Chromlaena odorata) Terhadap Kecepatan Pembekuan Darah

Penyembuhan luka akan melambat bila terjadi infeksi terus-menerus. Salah satau cara mencegah terjadinya  infeksi pada luka adalah dengan mempercepat pembekuan darah pada luka sehingga memperkecil kemungkinan terjadinya infeksi. Penelitian ini adalah penelitian true experiment, menggakan rancangan acak lengkap yang terdiri atas 6 perlakuan, yaitu perasan daun kopasanda konsentrasi 25%, 50% dan 100%, dan ekstrak daun kopasanda konsentrasi 5%, 10% dan 15%, untuk melihat efek perlakuan digunakan kontrol. Sampel yang digunakan adalah darah yang diambil dari 12 orang dewasa usia 20-25 tahun yang bergolongan darah A, B, AB dan O masing-masing 3 orang. Tiap perlakuan menggunakan setetes darah yang diulang 3 kali sehingga diperoleh 252 unit percobaan. Data yang diperoleh dianalisis dengan uji one way ANOVA dan dilanjutkan dengan uji BNJ pada taraf kepercayaan 95%. Hasil penelitian menunjukkan bahwa perasan daun kopasanda memperlambat kecepatan pembekuan darah secara signifikan, sedangkan ekstrak daun kopasanda konsentrasi 10% dan 15% mempercepat pembekuan darah secara signifikan. Oleh karena itu disimpulkan bahwa daun kopasanda berpengaruh nyata terhadap kecepatan pembekuan darah

The effect of giving cabbage litter on population growth of the african night crawder earthworm (Eudrilus eugeniae)

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

This research aims to; (1) evaluate the effect of red betel leaves\u27 extract in reducing the glucose level of mouse, (2) determine the effective extract dosage of red betel leaves.. The samples were gained by using random sampling technique. Moreover, the samples were divided into 4 groups, one controlling group and three experimental groups. In addition, the glucose was measured by glucometer. In addition, the glucose data was analyzed by using Anova one way test and continued to post hoc test.. The result of Anova test shown that p 0,001<A 0,05 so H0 was rejected. It meant that there was an effect of red betel leaves\u27 extract in reducing the glucose level of mouse. The result of post doc shown that there was significant different on reducing glucose in every level of dosage tested.. The conclusion of this research was : (1) red betel leaves\u27 extract significantly reduced the glucose level of mouse, (2) the dosage of 0,078 gr/20gr BB was already effective to reduce the glucose level of mouse
