Analysis of Students Basic Teaching Skills on Teaching Practice of Micro-Teaching Courses
Full text linkBasic 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
Effectiveness of post particular prolactin administration on follicle development the count in mice (Mouse muscle) female
Full text linkThis 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)
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
The use of banana peel as feed to increase growth of earthworms (Lumbricus rubellus)
Full text linkResearch 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
Utilization of Pregnant Mare Serum Gonadotrophin (PMSG) for Superovulation in Earthworm (Lumbricus rubellus) Cocoon Production
Full text linkEarthworms (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
Growth response of pakcoy (Brassica rapa L.) due to difference dosage and time of giving bokashi
No full textPakcoy is one of the commodities favored by the people of Indonesia. The presence of nutrients aroundÃÂ the plant root system greatly affects the growth of pakcoy. The availability of nutrients can be increased by fertilizing. Fertilization of plants can be done by using bokashi. Study on the growth response of pakcoy due to differences in dosage and time of giving bokashi was conducted to determine: (1) the growth response of pakcoy due to bokashi treatment,ÃÂ (2) the growth response of pakcoy due to difference in the time of giving bokashi, (3) the growth response of pakcoy due to the interaction between the dose and the time of giving bokashi. Completely randomized design with 3 replications was used in the study. The growth pakcoy parameters were plant height, number of leaves and leaf length. The result showed that: (1) plant height, number of leaves and leaf length had a positive response to bokashi treatment with the best bokashi dose is 15 tons per hectare, (2)ÃÂ plant height, number of leaves and leaf length of pakcoy responded to the time of giving bokashi, the highest growth parameters were pound in pakcoy given bokashi 30 days before planting. (3) plant height, number of leaves and leaf length were not significantly different due to the interaction between dose and time giving bokash
The Effect of Adding Vegetable Waste to Feed on The Growth of Earthworms (Lumbricus rubellus)
Full text linkEarthworms 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
