Tensimeter adalah instrumen fisika yang digunakan untuk mengukur tekanan darah. Tekanan darah terukur adalah tekanan relatif antara tekanan didalam pembuluh darah dibandingkan dengan tekanan udara luar atau atmosfer. Pengukuran tekanan darah menggunakan tensimeter digital jauh lebih tepat dibandingkan dengan pengukuran menggunakan tensimeter spring maupun tensimeter raksa. Pengukuran dengan tensimeter spring di salah satu klinik di kota mataram menunjukkan kesalahan pengukuran hingga 34% dibandingkan dengan tensimeter digital, sementara dengan menggunakan tensimeter raksa menunjukkan perbedaan sebesar 26%. Dari penelitian ini didapatkan bahwa pengukuran menggunakan tensimeter digital lebih akurat, sehingga penggunaan tensimeter jenis ini sangat direkomendasikan untuk pengukuran klinis di rumah sakit dan klinik Kesehatan.Keywords: pengukuran tekanan darah, tensimeter digital, tensimeter spring, tensimeter raksa.
Tensimeter是测量血压的物理工具。测量的血压是血管内压力与外部空气或大气压力之间的相对压力。用数字tensimeter测量与使用spring和raksa tensimeter测量要精确得多。在马塔兰市的一家诊所,用spring tensimeter测量结果显示,与数字tensimeter相比,测量误差为34%,而使用raksa tensimeter则显示26%的差异。从这项研究中发现,使用数字tensimeter更准确,因此对医院和健康诊所的临床测量高度推荐使用这种类型的tensimeter。重点词:测量血压,数字tensimeter, spring tensimeter, raksa tensimeter。

Abstract: Kelerengan kasih lepas sangat tergantung pada koefisien gesek statis antar partikel hasil lepas dan gaya normal yang bekerja pada bidang gelincir antar pasir lepas tersebut. Getaran gempa dapat menurunkan besarnya gaya normal akibat turunnya percepatan sebagai akibat adanya akselerasi dari suatu getaran. Perubahan kelerengan berbanding lurus dengan amplitudo getaran gempa dan juga berbanding lurus dengan frekuensi getaran gempa. Penelitian ini merupakan kajian teoritis yang mencoba menghubungkan antara stabilitas kelerengan pasir lepas akibat adanya perubahan akselerasi sebagai akibat dari getaran gempa bumi.
抽象:自由折叠的爱的游离完全依赖于在松散的沙地上滑行的不规则颗粒之间的静态滑动和正常的力。地震振动可以降低正常力的强度,这是由于地震的加速。振动的振动与地震振幅的直线变化成正比,也与地震振动的频率成正比。这项研究是一项理论,试图将近沙的稳定性与地震的加速变化联系起来。

Calculation Algorithm of Occurrence Probability (COP) of Self Potential Data. Self potential is often also called spontaneous potential is one of the geophysical methods that is based on the electrical properties of the material below the earth surface. Self potential arises due to the presence of electric charged of minerals that come in contact with electrolyte solutions around these minerals. Charge Occurrence Probability (COP) is one method of interpreting self potential data. The measurement of self potential on the surface is carried out using two porouspot electrodes made of copper which are immersed in copper sulfate or perusi. The COP calculation algorithm performed in this study is intended for users of the Matlab program. The research algorithm consists of two kinds, namely two-dimensional algorithm and 3-dimensional algorithm. Two-dimensional algorithm is performed on a line in a certain direction through the center of the anomaly. Three-dimensional algorithm is performed by the gridding method which is generated from the 2-dimensional calculation algorithm. Theoretically the resolution generated from this algorithm depends on the density of self potential data. Key Words: Self Potential, Spontaneous, Charge Occurrence Probality, COP
自电位数据发生概率(COP)计算算法。自电位法也常被称为自发电位法,是一种基于地下物质电学特性的地球物理方法。自身电位的产生是由于矿物的带电与这些矿物周围的电解质溶液接触。电荷发生概率(COP)是解释自电位数据的一种方法。在表面上的自我电位的测量是使用两个由铜制成的多孔电极浸泡在硫酸铜或perusi中进行的。本研究中执行的COP计算算法是针对Matlab程序的用户。研究算法包括两种,即二维算法和三维算法。二维算法通过异常中心在某一方向的直线上进行。三维算法采用由二维计算算法生成的网格化方法进行。从理论上讲,该算法产生的分辨率取决于自电位数据的密度。关键词:自电位,自发,电荷发生概率,COP

Penelitian ini bertujuan untuk mengembangkan multimedia interaktif fisika dan mengetahui pengaruhnya terhadap hasil belajar dan keterampilan generik sains siswa. Penelitian ini menggunakan desain penelitian dan pengembangan model ADDIE yang dimodifikasi menjadi tiga tahap, yaitu tahap studi pendahuluan, tahap pengembangan media, dan tahap uji coba media. Tahap studi pendahuluan dilaksanakan dengan studi kepustakaan dan penelitian pendahuluan. Tahap pengembangan media menghasilkan draft media. Penelitian dilanjutkan dengan tahap implementasi ujicoba terbatas dan ujicoba lebih luas di SMAN 1 Labuhan Haji Lombok Timur. Pembelajaran materi fluida dinamis di kelas eksperimen menggunakan multimedia interaktif sedangkan di kelas kontrol menggunakan pembelajaran konvensional. Selanjutnya hasil pembelajaran di kedua kelas dianalisis menggunakan uji Anava dua jalan dan skor gain ternormalisasi (N-gain). Berdasarkan hasil penelitian disimpulkan bahwa pembelajaran menggunakan multimedia interaktif secara signifikan meningkatkan hasil belajar dan keterampilan generik sains siswa.      Kata kunci: multimedia interaktif; pendekatan saintifik; hasil belajar, keterampilan generik sains, motivasi belajar 
本研究旨在开发互动多媒体物理,并了解其对学生科学的学习和一般技能的影响。该研究将经过改造的ADDIE模型的研究和开发设计设计为前期研究阶段、媒体开发阶段和测试阶段。初步研究的阶段是与文学研究和初步研究一起进行的。媒体开发阶段产生了媒体草案。研究继续进行,在东龙目岛探险第一行将进行有限的试验和更广泛的试验。在实验课上使用互动多媒体学习动态流体材料,在控制课上使用传统学习。接下来,两门课的学习结果都采用了双程Anava测试和重整分数进行分析。关键词:多媒体互动;科学方法;学习成果,一般科学技能,学习动机
