    Shear strength parameters of soils are cohesion (c) and internal friction angle (�). Direct shear test is a method to determine these parameters. Data from this test are shear stress and thickness change of soil. In practice, only the maximum shear stress will used to determine the shear strength parameter. The major objective of this research is to develope a formula for prediction internal friction angle (ϕ) by dilatation angle (α). Result of this research is a prediction formula of internal friction angle, as : α = arctan (µ + tan α)/(1- µ tan α by µ= 0,55. Dilatation angle (α) for this formula was determined at maximum shear stress.. Validations of ϕ predicted by this formula have maximum error 16,76%, average error 5,59% and standard deviation error 4,75%. Cohesion (c) values can calculated by Mohr-Coloumb Formula

    Tujuan dari penelitian ini adalah untuk mengetahui apakah terdapat peningkatan signifikan dari performa berbicara siswa setelah pembelajaran melalui gambar berseri. Desain pre-test dan post-test satu kelompok digunakan dalam penelitian ini. Hasil penelitian membuktikan bahwa terdapat perbedaan signifikan dari pencapaian siswa dalam performa berbicara sebelum dan sesudah pembelajaran melalui serial gambar. Nilai rata-rata dari pre-test adalah 57 dan post-test adalah 84. Dengan membandingkan rata-rata dari pre-test dan post-test, itu dapat diketahui bahwa peningkatan rata-rata adalah 27. Ini membuktikan bahwa skor siswa meningkat dengan signifikan karena p<0.05 (p=0.000). Berdasarkan data, ini dapat disimpulkan bahwa terdapat perbedaan signifikan dari pencapaian siswa dalam performa berbicara sebelum dan sesudah pembelajaran melalui gambar berseri. Oleh karena itu, mengajar menggunakan gambar berseri dianjurkan untuk digunakan oleh para guru agar meningkatkan performa berbicara siswa.The objective of this research is to know whether there is a significant improvement of the students’ speaking performance after being taught through series pictures. The one group pre-test and post-test design was used in this research. The result of the research proved that there is a significant difference of students’ achievement in speaking performance before and after being taught through series pictures.The mean score of pre-test was 57 and post-test was 84. By comparing between the mean of pre-test and post-test, it can be found that the increase of the mean was 27. It proved that the students’ scores increase significantly because p<0.05 (p=0.000). Based on the data, it can be concluded that there is a significant difference of students’ achievement in speaking performance before and after being taught through series pictures. Therefore, series pictures is recommended to be used by teachers to improve the students’ speaking performance

    Superoxide Dismutase (SOD) is an antioxidant enzyme which reduce anion superoxide radicals as well as known caused of diabetes. There are many natural additive was believed having capacity to repaired an antioxidant celluler status. Cardamom's stem were reported containing flavonoid and vitamin C which have been proven as in vitro antioxidant. There was no data showing its in vivo potency. This study aims to knoe the SOD activity of diabetes rats which were given cardamom stem extract (CSE) and glibenclamide. The research carried out with the use of experimentally Randomized Design Complete (RAL) by administering treatment on diabetes rat without CSE and glibenclamide as a control, consist of 100 mg/kg bodymass CSE and 2 mg/kg bodymass glibenclamide. The experiment consists of 3 treatments with 7 repetitions, blood sampling carried out experiments as much as 3 times with intervals of 7 days once. The data was analyzed using a variety of analysis (ANOVA). The result showed that the SOD activity increased from 4261 Unit/mg protein to 6604,668 Unit/mg protein (P<0.01) in diabetes rats treatment by CSE for 14 days

    Impact of a catch-up strategy of DT-IPV vaccination during hospitalization on vaccination coverage among people over 65 years of age in france: The HOSPIVAC study (Vaccination during hospitalization)

    In France, diphtheria tetanus and inactivated polio vaccine (DT-IPV) coverage and immunization are insufficient in the elderly and decrease with age. The principal objective of this study was to assess the impact of a strategy of catch-up DT-IPV vaccination during hospitalization in people over the age of 65 years in central France (the Sarthe region). We performed a prospective, single-center, cluster-randomized study (four hospital wards). We included patients aged &ge;65 years, without mental impairment, contraindication and who accepted to participate, hospitalized in the internal medicine wards in Le Mans Hospital from 28 May 2018 to 27 May 2019. The DT-IPV vaccination status of the patients was determined at inclusion and the wards were randomized (intervention and control). In the intervention group, vaccination was up-dated during hospitalization. In case of temporary contraindication, vaccination was prescribed at hospital discharge. Patients hospitalized in the control wards received oral information only. Final immunization status was determined by calling the patient&rsquo;s general practitioner two months after hospital discharge. One hundred and fifty seven patients were included: 73 in the intervention and 84 in the control arm. Baseline immunization coverage was 46.5%. Vaccination coverage increased from 56.2% to 80.8% in the intervention group and from 38.1% to 40.5% in the control group (p &lt; 0.001). Having received sufficient information from the general practitioner was the only factor associated with vaccination being up-to-date in uni- and multivariate analysis: OR = 5.07 [2.45&ndash;10.51]. In a setting of low vaccination coverage DT-IPV vaccination during hospitalization is an effective catch-up strategy

    Pada sistem distribusi, kualitas keandalan dapat dilihat dari lamanya pemadaman atau SAIDI (System Average Interruption Duration Index) dan seberapa sering pemadaman terjadi dalam satuan waktu atau SAIFI (System Average Interruption Frequency Index). Sebuah upaya yang telah dilakukan oleh PT. PLN (persero) Distribusi Bali AJ Bali Selatan untuk mengurangi jumlah pelanggan padam saat terjadi gangguan yaitu dengan cara pemasangan LBS Three Way. Berdasarkan hasil perhitungan kualitas keandalan pada penyulang Gunung Agung setelah pemasangan LBS Three Way yaitu SAIFI sebesar 0.989688526 dan SAIDI sebesar 5.737530618, penyulang Imam Bonjol setelah pemasangan LBS Tree Way yaitu SAIFI sebesar 0.683913253 dan SAIDI sebesar 3.908243775. Hasil analisa pengaruh pemasangan LBS Three Way terhadp pelanggan DB0133 (United Overseas Bank) yaitu pelanggan pada DB133 tidak mengalami pemadaman apabila terjadi gangguan pada penyulang Gunung Agung karena pelanggan dapat dimanuver oleh penyulang Imam Bonjol. Berdasarkan perhitungan kemampuan manuver beban pada penyulang Gunung Agung dan Imam Bonjol dapat dikatakan penyulang Gunung Agung mampu memanuver beban seksi I dan III pada penyulang Imam Bonjol, dan penyulang Imam Bonjol mampu memanuver beban seksi III, IV dan V pada penyulang Gunung Agung.</em
