Biometric similarity Test of The Population of T. (Zaria) bantamensis tjicumpaensis with T. (Zaria) javana as a Form of Phylogeny And Evolutionary Proximity

Biometric aspects in the Turritellidae family need to be studied as an important identification parameter. Zaria, which is one of the sub genera in the Turritellidae family, deserves to be tested in order to determine the feasibility of the biometric aspect as an identification parameter. This paper aims to provide an overview of the benefits of the biometric aspect as an identification parameter. The method used to re-identify the biometric and morphological aspects of the T. (Zaria) bantamensis tjicumpaensis population with T. (Zaria) javana. The results of the identification were carried out by a T-Test on the biometric aspect to see the similarity of the biometric aspects of the two populations. Based on the results of the T-Test on the parameters of the Wsut: Wang and Wsut: L ratio, it shows that the two Zaria species are the same. Meanwhile, from the morphological aspect, there is a slight difference in the early growth peripherals.

A generic test for the similarity of spatial data

Two spatial data sets are considered to be similar if they originate from the same stochastic process in terms of their spatial structure. Many tests have been developed over recent years to test the similarity of certain types of spatial data, such as spatial point patterns, geostatistical data and images. This research proposes a generic spatial similarity test able to handle various types of spatial data, for example images (modelled spatially), point patterns, marked point patterns, geostatistical data and lattice patterns. A simulation study is done in order to test the method for each spatial data set. After the simulation study, it was concluded that the proposed spatial similarity test is not sensitive to the user-defined resolution of the pixel image representation. From the simulation study, the proposed spatial similarity test performs well on lattice data, some of the unmarked point patterns and the marked point patterns with discrete marks. We illustrate this test on property prices in the City of Cape Town and the City of Johannesburg, South Africa.

Adaptation of Situ Bagendit, Rindang 1 and Rindang 2 Varieties in Shallow Swamp Ogan Komering Ilir District South Sumatera

Shallow swamps can be used for rice production during the dry season. The problem that occurs is lack of water. The technology needed to overcome these problems is drought tolerant superior varieties. The purpose of this study is to obtain superior varieties tolerant to drought on shallow lebak swampy. The study was conducted from April 2019 to August 2019. The varieties used were Situ bagendit, Rindang 1, Rindang 2, and the Siam (local) as comparison. Data collected included: plant height, number of productive tillers, number of grains per panicle, number of filled grains per panicle, number of empty grains per panicle and production. The method used is direct observation in the field. The data obtained were compiled by tabulation and analyzed by statistical tests namely the similarity test of the middle value (t-test). The results showed that the varieties Situ Bagendit, Rindang 1, and Rindang 2 had better numbers of productive tillers, number of grains per panicle, and number of filled grains per panicle than Siam varieties. The highest production was achieved by the Situ Bagendit variety, namely 4.6 tonnes/ha. Meanwhile, the production of Rindang 2, Rindang 1, and Siam varieties were 4.4; 4.0; and 2.0 tonnes/ha.

Efektivitas Three Finger Grip Dengan Four Finger Grip Terhadap Akurasi Sidehand Throw Posisi Infield Olahraga Softball

The background of this research is that players often make mistakes when throwing a side throw at the Infield position. The formulation of the research problem is which is more effective using Three Finger Grips with Four Finger Grips to the accuracy of Sidehand Throw at the Infield position in Softball, Softball Team, Universitas PGRI Semarang 2020. The purpose of this study is to see the effectiveness of the throws using Three Finger Grips with Four Finger Grip on the accuracy of the Sidehand Throw at the Infield position in Softball, the Softball Team of the PGRI University Semarang 2020. In this research, to collecting the data is using a descriptive method. The technique of analysis is using a significant similarity test for two means (one party). In this study, the samples used 13 male students of the softball team Universitas PGRI Semarang 2020 with the saturated sampling technique. The mean of three fingers is 22, the standard deviation (Std.Deviation) is 3.78, the minimum and maximum of values are 18 and 30, the mean of four fingers is 26, the standard deviation (Std. Deviation) is 4.89, minimum and maximum of values are 20 and 34. The results of the calculation obtained the value of thitung (2,086) > ttabel (1,70) so that H0 is rejected, which can be concluded that the four-finger grip is more effective than three-finger grips on sidehand accuracy throw at the infield position in the softball team of Universitas PGRI Semarang 2020. The conclusion using a three-finger grip on the accuracy of the sidehand throw at the infield position in the softball team Universitas PGRI Semarang 2020 are categorized as effective. While the results of the throw using four-finger grips on the accuracy of sidehand throws at the infield position in the softball team Universitas PGRI Semarang 2020 are categorized as effective. The four-finger grip is more effective than the three-finger grip on the accuracy of sidehand throws at the infield position in the softball team Universitas PGRI Semarang 2020. It is hoped that athletes can use the four-finger grip because it is more effective for the accuracy of sidehand throws at the infield position in softball. Keywords: Three Fingers, Four Fingers, Sidehand Throw Infield Softball. Latar belakang dari penelitian ini adalah pemain sering melakukan kesalahan saat melakukan lemparan samping pada posisi infield.

Pengaruh Penggunaan Video Pembelajaran Terhadap Hasil Belajar Komputer 1 Mahasiswa Pendidikan Matematika Semester II TP. 2019/2020 Universitas Pasir Pengaraian

The computer 1 learning outcomes of the second-semester students of the Mathematics Education study program are low because the instruments used have not used instructional videos. A solution is needed in the form of the use of instructional videos. This study wanted to see whether or not there was an effect of instructional videos on the learning outcomes of computer 1. The quasi-experimental method used in this study was that the class A was the experimental class and class B was the control class. The sampling technique used is the saturated sampling technique, where all populations are used as research samples. The average similarity test was used in analyzing quantitative data, while the qualitative data were analyzed descriptively. The average similarity test results utilizing the t-test show where the value of tcount > ttable that 2,56 > 2,015, so it can be concluded that there is an effect of the use of instructional videos on computer 1 learning outcomes second-semester students of the mathematics education study program 2019/2020.
