ANALISIS KONSEP MATEMATIKA SEKOLAH DALAM PEMULASARAAN JENAZAH

This research aim to identify the elementary and junior high school mathematic concepts which included the funeral procession. The process of funeral procession that was researched included measuring and cutting the shroud, bathing the corpse, shrouding the corpse, praying the corpse, and burying the corpse. The method of this research is a qualitative, and the form of this research is a literature study. Then the data were collected using documents in the form of books, articles, and notes on the results of the funeral procession by the fardhu kifayah team of Ummu Al-Athiyyah Al-Anshoriyyah. Based on the Miles and Huberman analysis method, elementary and junior high school mathematical concepts are found in the funeral procession, namely rectangles, mixed arithmetic operations, addition, subtraction, multiplication, division, number sequences, sets, linear inequalities of one variable, line segments, vertical lines, horizontal lines, parallel lines, perpendicular lines, point outside the line, 180 degree angel, and cuboids.

MENGASAH KREATIVITAS BERFIKIR PADA FUN DAY SCHOOL DI SD NEGERI 002 TANJUNG PIAYU CONCERNING THINGKING CREATIVITIES IN FULL DAY SCHOOL AT SD NEGERI 002 TANJUNG PIAYU

SD Negeri 002 Tanjung Piayu merupakan salah satu SD di pesisir Pulau Batam. Sebahagian besar pekerjaan orang tua siswa adalah nelayan. Dalam proses belajar mengajar masih bersifat teacher centerd yang bersifat kaku dan membosankan. Untuk itu dilakukan kegiatan pengabdian masyarakat bagi siswa SD Negeri 002 ini guna menciptakan suasana di sekolah menjadi menyenangkan, educatif dan dapat mengasah kreativitas berfikir siswa. Dengan menggunakan metode pemberian games edukatif yang disesuaikan dengan kelas peserta didik. Untuk siswa kelas 4 sebanyak 40 orang dan diberikan puzzle angka, mewarnai dan Happy Games. Untuk siswa kelas 5 sebanyak 38 orang dan diberikan English for Fun. Dan untuk siswa kelas 6 sebanyak 30 orang dan diberikan berupa game kartu angka penjumlahan, pengurangan, perkalian dan pembagian. Setiap game dilakukan secara berkelompok. Dari kegiatan diperoleh bahwa dengan menggunakan game dapat menjadi salah satu alternatif dalam penyampaian edukasi serta dapat meningkatkan kreativitas berfikir siswa di SD Negeri 002 Tanjung Piayu.Kata Kunci: Sekolah Dasar, Game, Edukatif, Kreativitas Berfikir SD Negeri 002 Tanjung Piayu is one of the elementary schools on the coast of Batam Island. Most of the work of parents is fishermen. In the teaching and learning process, it is still teacher centerd that is rigid and boring. For this reason, community service activities are carried out for SD Negeri 002 students in order to create an atmosphere in school to be fun, educative and able to concered students' creative thinking. By using the method of providing educational games that are tailored to the class of students. For grade 4 students as many as 40 people and given number puzzles, coloring and Happy Games. For grade 5 students as many as 38 people and given English for Fun. And for grade 6 students as many as 30 people and given in the form of addition, subtraction, multiplication and division number card games. Every game is done in groups. From the activity, it was found that using games can be an alternative in delivering education and can improve the creativity of students thinking in SD Negeri 002 Tanjung Piayu.Keywords: Elementary School, Game, Educative, Thinking Creativity

A new class of cyclin dependent kinase in Chlamydomonas is required for coupling cell size to cell division

Proliferating cells actively control their size by mechanisms that are poorly understood. The unicellular green alga Chlamydomonas reinhardtii divides by multiple fission, wherein a ‘counting’ mechanism couples mother cell-size to cell division number allowing production of uniform-sized daughters. We identified a sizer protein, CDKG1, that acts through the retinoblastoma (RB) tumor suppressor pathway as a D-cyclin-dependent RB kinase to regulate mitotic counting. Loss of CDKG1 leads to fewer mitotic divisions and large daughters, while mis-expression of CDKG1 causes supernumerous mitotic divisions and small daughters. The concentration of nuclear-localized CDKG1 in pre-mitotic cells is set by mother cell size, and its progressive dilution and degradation with each round of cell division may provide a link between mother cell-size and mitotic division number. Cell-size-dependent accumulation of limiting cell cycle regulators such as CDKG1 is a potentially general mechanism for size control.

Dynamic Discrete GM (1,1) Model and Its Application in the Prediction of Urbanization Conflict Events

In the empirical researches, the discrete GM (1,1) model is not always fitted well, and sometimes the forecasting error is large. In order to solve this issue, this study proposes a dynamic discrete GM (1,1) model based on the grey prediction theory and the GM (1,1) model. In this paper, we use the equal division technology to fit the concavity and convexity of the cumulative sequence and then construct two dynamic average values. Based on the dynamic average values, we further develop two dynamic discrete GM (1,1) models and provide the gradual heuristics method to draw the initial equal division number and the dichotomy approach to optimize the equal division number. Finally, based on an empirical analysis of the number of conflict events in the urbanization process in China, we verify that the dynamic discrete GM (1,1) model has higher fitting and prediction accuracy than the GM (1,1) model and the discrete GM (1,1) model, and its prediction result is beneficial to the government for prevention and solution of the urbanization conflict events.

Assembly Unit Division Method Based on Connection Strength

Through analysing the assembly relation between the product parts, this paper divided the product parts into function parts and the connectors. Then the simplified assembly semantic relation graph model was established in this paper. The concept of assembly connection strength was introduced to express the complexity of assembly between the parts. Using the least assembly time as the goal to determine the optimal unit division number, the assembly unit division was accomplished based on the connection strength. Finally using the spindle box of HTC2500hs as an example to check this division method, the results show that this method has applicability and effectiveness.
