Effectiveness of post particular prolactin administration on follicle development the count in mice (Mouse muscle) female

This study aims to test the effectiveness of postpartum prolactin administration on follicle development in the count in mice (Mouse muscle). This type of research is a true experiment using a completely randomized design (RAL). The sample for this study was mice (Mouse muscle) female strain BALB/C, aged ± 4 months with a body weight between 25-30 gr in a healthy condition and not pregnant. The data obtained was analyzed using the One-way analysis of variance (F test) with a significance level of 0.05, followed by the Least Significant Difference test (BNT. The research results show that the sig. (p) = 0.001< α = 0.05, so it can be concluded that postpartum administration of prolactin has a significant effect on follicular development of the count in mice (Mouse muscle)

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 Tapak Dara (Catharanthus roseus) Leaf Extract on The Growth of Mice (Mus Musculus) Ovarian Follicles

Tapak dara (Catharanthus roseus) leaf contain phytoestrogen compounds such as flavonoids, isoflavonoids, saponins, and tannins, and contain alkaloid compounds. Phytoestrogens are compounds contained in plants, having a chemical structure resembling 17β-Estradiol in the body's natural estrogen. This study aims to determine the effect of tapak dara leaf extract on the growth of ovarian follicles of mice (Mus musculus), consisting of primary follicles, secondary, tertiary, and de Graaf follicles. This research method is true experiment and Posstest-Only Control with a quantitative approach. Sampling was carried out randomized block design (RBD). The growth of mice ovarian follicles is known by counting the number of mice ovarian follicles, analyzed using the ANOVA one-way test analysis method at a sig. level of 5% (α = 0.05), then if there is a difference, proceed with a further test of Least Significant Difference) at a sig. level of 5% (α = 0.05). Data analysis using Microsoft Excel 2010. The results of the hypothesis test using One Way ANOVA stated that Fcalculate > Ftable at sum of primary follicles, which means that there is a real difference and Ha is accepted. The results of hypothesis tests at sum of secondary, tertiary, and de Graaf follicles stated that Fcalculate < Ftable, which means there is no real difference and Ha is rejected. The conclusion of this study is that tapak dara leaf extract has a significant effect on the growth of primary follicles, but does not significantly affect the growth of secondary, tertiary, and de Graaf follicles

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
