The Relationship between Learning Motivation and Learning Outcomes of Students Chemistry of Grade XI-MNS in 4 State SHS Pematangsiantar

This study aimed to determine the relationship between learning motivation and learning outcomes of students chemistry of grade XI-MNS (mathematics and natural science). The research design used was quantitative with a correlation approach. The population of this study was all students of class XI-MNS at state senior high school (SHS) 4 Pematangsiantar as many as 205 students for the 2019/2020 Academic Year. The sampling technique for this research was random sampling, which is a random sampling technique with a total sample of 40 students. The instrument used in the study was a non-test (questionnaire) of 20 questions to measure student learning motivation, but measuring chemistry learning outcomes was taken from the odd semester exam scores. The results showed that the percentage of high motivation was 20%, sufficient motivation was 50%, and low motivation was 30%. Student chemistry learning outcomes with a minimum score with a score of 41 and a maximum value with a score of 63 derived from the semester test scores that have been assessed by the field teacher. The correlation coefficient (r) in this study is 0.80 and the value of the coefficient of determination (r²) amounting to 0.63 which indicates that students' chemistry learning outcomes affect 63% changes in chemistry learning motivation. This results show that the relationship between learning motivation and learning outcomes of students chemistry of grade XI-MNS is very strong

Studi Eksperimental Pengaruh Variasi Temperatur Pemanasan Awal Cetakan Horizontal CENTRIFUGAL CASTING PADA PENGECORAN Al-Si TERHADAP SIFAT MEKANIK DAN CACAT CORAN

ABSTRAK Pengecoran sentifugal merupakan metode yang efektif untuk membuat benda coran, namun perlu diperhatikan parameter-parameter dari pengecoran sentrifugal seperti temperatur logam cair yang akan dituang, temperatur cetakan, kecepatan putar cetakan, dan gaya sentrifugal yang terjadi. Dari parameter tersebut fokus pada penelitian ini adalah pada parameter temperature cetakan dengan Tujuan dari penelitian ini adalah mengetahui variasi tempratur pemanasan awal cetakan horizontal centrifugal casting sebagai upaya untuk meningkatkan kualitas produk coran yang dilakukan dengan perbaikan proses pengecorannya salah satunya dengan metode pengecoran sentrifugal. Bahan yang digunakan dalam penelitian ini adalah Al-Si dengan penambahan Si sebesar 30%. Variasi temperature pemanasan awal yang digunakan dalam penelitian ini adalah 100 oC, 200 oC dan 300 oC. Cacat yang banyak terjadi pada preheating 100 oC. dari mulai cacat salah alir, cacat porositas dan cacat retakan. Nilai kekerasan dari masing-masing variasi preheating 100 oC, 200 oC dan 300 oC adalah 174,50 BHN, 181,23 BHN dan 196,22 BHN. Kekerasan tertinggi didapat pada preheating 300 oC. Nilai energi serapan yang diperoleh dari masing-masing variasi preheating 100 oC, 200 oC dan 300 oC adalah 14,32 joule, 15,27 dan 17,84 Joule. Nilai energi serapan tertinggi didapat pada preheating 300 oC.   Kata kunci : Centrifugal casting, preheating, Al-S

Phytochemical Screening and Antibacterial Activity of Leaves Extract Balangla (Litsea cubeba (Lour) Pers.) from Malinau, East Borneo

Balangla (Litsea cubeba) plant is used as traditional medicine by Dayak Kenyah tribe in East Kalimantan. It contains active compounds that are efficient to treat many human diseases and believed to have an antibacterial activity. The purposes of this study were to determine the phytochemical compounds of the balangla leaves and to investigate the antibacterial activity of ethanol extract of leaves L. cubeba. Respectively, various levels of ethanol extract of L. cubeba leaves viz: 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 100% were used to examine its antibacterial activity against bacteria gram positive (Staphylococcus aureus) and gram negative (Escherichia coli) by using pitting diffusion method. The results indicated that alkaloids, flavonoids, phenols and steroids have been found as phytochemical compounds in the ethanol extracts of L. cubeba leaves. Meanwhile, the antibacterial activities of ethanol extracts of L. cubeba leaves against the test organisms had been determined and significantly inhibited the growth of S. aureus and E. coli, forming a wide inhibition zone (15.91±0.950 mm) for S. aureus and (16.23±0.416 mm) for E. coli. Further, antibacterial activity of (L. cubeba) in-vitro had been justified on its utility in traditional medicines for the treatment of infections of bacterial origin

FAKTOR–FAKTOR YANG BERHUBUNGAN DENGAN BAYI BERAT LAHIR RENDAH DI KABUPATEN TAPANULI UTARA TAHUN 2022

Infant mortality is related to the weight of the newborn. The weight of a newborn is a benchmark used to assess the degree of public health. If a newborn weighs less than 2500 grams, it is called a low birth weight baby (LBW). The causes of LBW are many and varied. Internal and external factors of the mother, fetus and other factors such as behavior. This study will examine the factors associated with Low Birth Weight Babies (LBW) in North Tapanuli Regency in 2022. This study is a cross-sectional study with a total sample of 34 people (total sampling). The results of the univariate test showed that 25 mothers gave birth to LBW and 9 LBW mothers. The results of the bivariate test showed that there was a relationship between parity, pregnancy distance and exposure to health information media with LBW. The results of the multivariate test showed that there was a significant effect between parity and the incidence of LBW with an OR value of 13,141, meaning that mothers with high parity had a 13,141 greater chance of having low birth weight in North Tapanuli Regency. The role of the family and posyandu is highly expected. Socialization and family planning campaigns are enhanced through the use of print, electronic, and social media
