Rubble mount breakwateris recently become the most widely used breakwater, consist both of natural and artificial stone. It required a large dimension of structure so that the investment costs become more and more expensive. One of the solutions that can be implemented is Hanging Sheet Pile breakwater. Unfortunately, the performance of this type of breakwater has not been known yet. Performance of this breakwater represented by wave energy transmission coefficient (KEt). Therefore, this study aims to examine the effect of relative draft (s/d) and relative wave height (H/s) to KEt. This study conducted in Ocean Technology Laboratory of Universitas Hasanuddin. The parameters studied are structure dimensions and wave parameters. Wave parameters consist of wave height (H) and wave period (T), while the structure parameter is the draft structure (D). The result of this study shows that the greater value of both incident wave steepness (Hi/gT2) and structure relative draft (s/d), then the smaller of KEt value will be achieved. Also, the greater relative H/s, the smaller KEt will be achieved. For all cases of study, the transmission coefficient ranges from 0.122 – 0.786.
Background: Only a few published studies have directly demonstrated the effects of local soy isoflavone on the post-menopausal vaginal maturation index. This study focused on the effect of 24 weeks of local soy isoflavone (67,5 mg) consumption to improve the post-menopausal vaginal maturation index.
Material and Methods: 50 post-menopausal women were randomly assigned to a double-blind clinical trial to receive cowpea (Vigna unguiculata) powder treatment (n=25) and placebo (n=23). Vaginal cytology (maturation index, maturation value) was evaluated at pre and post-treatment in Anatomy Pathology Laboratories. Collected data were analyzed by using the analysis of covariant (ANOVA) method.
Result: There is no difference in maturation vaginal index between the treatment and the placebo group. The treatment was not significantly improved the vaginal maturation index (p<0,05). The concomitant variable, age, post-menopausal interval, BMI, marital status, and initial cell condition have no significant effect on the maturation vagina index.
Conclusion: Cowpea powder supplement with 67,5 mg isoflavone cannot improve the vaginal maturation index on post-menopausal patients.
Field testing is divided into 2 tests i.e. by destroying test structures or destructive tests and without destroying the structure or called a non-destructive test (NDT) One of them using the ultrasonic pulse rate (UPV). The study used the PUNDIT PL-200 tool to perform a concrete density analysis process based on the parameters generated from the UPV tool. The parameters taken on this test are rapid ultrasonic wave velocity. The study used a cylinder test object with a diameter of 15 cm and a height of 30 cm. Test objects are differentiated into 4 age of concrete 7 days, 14 days, 21 days, and 28 days. The results that get in the study's quick value of wave vines are constantly increasing according to the age
Penelitian ini bertujuan untuk mengetahui gambaran pelaksanaan pembelajaran dan penilaian pada mata pelajaran pemesinan bubut selama masa pandemi Covid-19. Penelitian ini merupakan penelitian survei. Data yang digunakan pada penelitian ini berasal dari dua guru mata pelajaran pemesinan bubut dan siswa kelas XI Teknik Pemesinan sejumlah 85 siswa. Teknik pengambilan data yang digunakan adalah observasi, angket, wawancara dan dokumentasi. Berdasarkan hasil analisis dan pembahasan data penelitian diperoleh bahwa proses pembelajaran di SMK N 1 Gombong berjalan dengan baik dan didukung dengan fasilitas praktik yang baik. Berdasarkan pendapat siswa dihasilkan bahwa pihak sekolah sudah sangat baik dengan melaksanakan praktik secara langsung, tetapi waktu yang singkat pada saat praktik menjadi kurang efektif untuk kompetensi membubut yang siswa peroleh. Pelaksanaan penilaian yang dilakukan oleh guru dibagi menjadi tiga tahap, yaitu perencanaan, pelaksanaan dan pengolahan nilai. Berdasarkan data, analisis, dan pembahasan, ketiga tahapan penilaian sudah masuk kategori sangat baik.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
