In order to investigate the difference of current toughness index standards for fiber reinforced concrete, two main groups of specimens were made to take bending toughness test with the requirements of corresponded standards, loading methods and loading speeds, which are ASTM C1018 in America, ACI 544 and JSCE G552 in Japan. United with software Origin, the load-deflection curves gathered from bending test was calculated with relative standards. The results show that the calculated toughness index value with ASTM C1018-98 in America is more accurate with three grades but the requested deflection of testing is much longer than others while ACI 544 and JSCE G552 in Japan are quite the contrary.

Widely used additive manufacturing technique for plastic materials is Fused Deposition Modelling (FDM). The FDM technology has gained interest in industry for a wide range of applications, especially today when large number of different materials on the market are available. There are many different manufacturers for the same FDM material where the difference in price goes up to 50%. This experimental study investigates possible difference in strength of the 3D printed PLA material of five different manufacturers. All specimens are 3D printed on Ultimaker S5 printer with the same printing parameters, and they are all the same colour.

Red dragon fruit flesh extract contains of anthocyanin as red pigmen that potentially to be a natural dye. Athocyanin contains of polysaccharide that can binding with polysaccharide of dental plaque called hydrogen bonds, so dental plaque has been colored and potentially as alternative of disclosing solution. The purpose of this study was to find out the difference of plaque index after smeared by red dragon fruit flesh extract 75% and disclosing solution. The method of this study is a clinical experimental study with a static-group comparison design. 20 subjects were examined the plaque index after smeared with red dragon fruit flesh extract 75%) and disclosing solution). There was no significant difference between groups. Conclusions: Red dragon fruit flesh extract 75% had similar capability with disclosing solution to examine dental plaque.

Abstrak Penelitian ini dilakukan untuk mengetahui strategi pengajaran kosakata dengan menggunakan (strategi bernyanyi). Rumusan masalah penelitian ini adalah (1) bagaimana proses strategi pengajaran kosakata bahasa Arab dengan menggunakan strategi bernyanyi, (2) bagaimana efektivitas penggunanan strategi pengajaran kosakata bahasa Arab dengan menggunakan strategi bernyanyi. Desain Penelitian yang digunakan adalah studi eksperimental.  Populasi dalam peneltian ini adalah seluruh mahasiswa progam Studi PBA di UIN Maulana Malik Ibrahim, adapun sampel yang diambil dari populasi tersebut adalah mahasiswa Program Studi PBA kelas B-4 UIN Maulana Malik Ibrahim Malang. Hasil dari penelitian ini menunjukkan bahwa (1) proses strategi pengajaran kosakata bahasa Arab dengan strategi bernyanyi yaitu aktivitas pra instruksional, petunjuk isi dan pembelajaran. Partisipasi peserta didik, penilaian, aktifitas timbal balik (2) efektifitas strategi pengajaran bahasa Arab dengan menggunakan strtegi bernyanyi menunjukkan nilai t-test lebih kecil daripadda t-tabel 0,243< 2, 0639, nilai t-test 0,243 itu berada diantara nilai interval konfidensi perbedaan, yaitu nilai tertinggi 1,901 dan nilai terendah 1,501 serta nilai signifikansi 0,810 yang mania lebih kecil dari t-table yaitu 2,0639     Abstract             This reserach elaborates on the teaching strategy of Arabic vocabulary by using the song. The research problems are: (1) what is the process of the teaching strategy of Arabic vocabulary by using the song; and (2) what is the effectiveness of the teaching strategy of Arabic vocabulary by using the song. The design of this study is experimental study. The population of this research is all students in PPBA UIN Maulana Malik Ibrahim Malang and the sample of this research is all students in class B-4 PPBA UIN Maulana Malik Ibrahim Malang. The result of this study is: (1) the process of the teaching strategy of Arabic vocabulary by using the song consist of several stages. They are pre instructional activities, content and learning guidance, learner participation, assessment, and follow-through activities; (2) the effectiveness of the teaching strategy of Arabic vocabulary by using the song is the value of t-test is smaller than t-table 0,243 < 2,0639, the value t-test 0,243 is between the value of confidence interval of the difference, upper 1,901 and lower -1,501, and signified value is 0,810 < t-table is 2,0639.     ملخص ويوضح هذا البحث التركيز في استراتيجية التدريس للمفردات العربية باستخدام الأغنية. وأما مشكلة البحث فهي: أولا، ما هي عملية إستراتيجية التدريس للمفردات العربية باستخدام الأغنية؛ وثانيا؛ ما هي فعالية استراتيجية التدريس للمفردات العربية باستخدام الأغنية. ويكون تصميم هذه الدراسة من نوع الدراسة التجريبية. أما مجتمع البحث لهذا البحث هو جميع الطلاب في قسم تعليم اللغة العربية بجامعة مولانا مالك إبراهيم الإسامية الحكمومية مالانج، والعينة من هذا البحث هو جميع الطلاب في الصف B-4 قسم تعليم اللغة العربية بجامعة مولانا مالك إبراهيم مالانج. والنتائج من هذه الدراسة هي: (1) عملية إستراتيجية التدريس للمفردات العربية باستخدام الأغنية تتكون من عدة مراحل. وهي أنشطة تعليمية سابقة، ومحتوى وإرشادات تعليمية، ومشاركة للمتعلم، وتقييم، وأنشطة متابعة. (2) أما فاعلية إستراتيجية التدريس للمفردات العربية باستخدام الأغنية هي قيمة اختبار t أصغر من t-تابل 0،243 <2،0639، قيمة t-تيست 0،243 بين قيمة فاصل الثقة في الفرق، العلوي 1،901 وأقل -1،501، وقيمة معترف بها هو 0،810 <t- الجدول هو 2،0639.

This research is a field experimental study that aims to find out the difference between the effects of non-ball smash exercises and silent ball smash exercises on the ability of volleyball smash on students of the FOK UNG Sports Coaching Education Study Program. The population and sample involved in this study were 60 students of the FOK UNG Sports Coaching Education Study Program. However, in accordance with the research design, two research groups were formed which consisted of ball-free smash exercises and silent ball smash exercises. The research was carried out for six weeks with frequency of exercise 3 times a week. Based on the results of data analysis using the paired t-test formula and the unpaired ttest at a significant level of 95%, it can be concluded as follows: There is a significant effect of smash training without the ball on the ability to do volleyball smash (to = 8,869> tt = 2,045 ). There is a significant effect of the silent ball smash exercise on the ability to do volleyball smash (to = 13,535> tt = 2,045). There is a significant difference in the effect between the smash ball practice without the ball and the silent ball smash exercise on the ability to do volleyball smash (to = 8,259> tt = 2,000)
