Analisa Non-Linier pada Mekanisme Keruntuhan Jembatan Rangka Baja Tipe Pratt

Steel truss bridge collapse often occurs, both in Indonesia and in other countries. As a result of the collapse of the bridge is in addition to the casualties also losses from the financial aspects. This collapse caused due to various factors, one of them because of a decrease in the strength of the bridge structure. To minimize required maintenance of the bridge\u27s collapse and to facilitate the maintenance of one of them must be known failure mechanisms existing bridges. In the analysis of this collapse, will be modeled steel truss bridge pratt\u27s type with long spans is 60 meters.  Analysis of the collapse of the steel truss bridge\u27s, utilizing a pushover analysis to analyze the behavior of the bridge structure. Pushover analysis done with give vertical static load pattern at the structure, next gradually increase by a factor until one vertical displacement target of the reference point is reached. The study shows that at model singe span failure occurred on the chord on mid span. The performance level of structure shows all models of bridges in the state are IO, this case based on the target displacement FEMA 356 and the actual ductility occurs in all models of bridges is compliant with SNI 2833-2008

Analisis Alternatif Tipe Pondasi Dan Ekskavasi-dalam Pada Lokasi Calon Tapak Pulau Panjang, Serang

ANALISIS ALTERNATIF TIPE PONDASI DAN EKSKAVASI-DALAM PADA LOKASI CALON TAPAK PULAU PANJANG, SERANG. Pulau Panjang merupakan salah satu lokasi alternatif yang sedang dikaji sebagai calon tapak PLTN. Tanah permukaannya didominasi oleh endapan pasir dan cangkang hingga kedalaman belasan meter, selain itu juga perselingan pasir dan lempung hingga kedalaman sekitar 120 m. Tujuan penelitian adalah menganalisis alternatif tipe pondasi dan simulasi pembuatan ekskavasi-dalam pada saat konstruksi pondasi khususnya terkait aspek kestabilan lereng. Metode yang digunakan meliputi pengumpulan data hasil analisis laboratorium mekanika tanah/batuan, pengukuran kecepatan gelombang geser dengan metode PS logging, dan analisis alternatif tipe pondasi dan ekskavasi-dalam. Hasil analisis tipe pondasi yang dapat diterapkan pada calon tapak Pulau Panjang adalah kombinasi dari pondasi rakit dan pile. Batuan dengan Vs > 400 m/s pada kedalaman 44 m dapat dijadikan sebagai dasar konstruksi pondasi rakit. Di bagian bawahnya disambung dengan pondasi pile yang dikonstruksi sampai batuan dasar dikedalaman 120 m pada Vs > 900 m/s. Hasil analisis kestabilan lereng pada ekskavasi dalam dengan ketinggian lereng 44 m, sudut vertikal, pada kondisi normal menghasilkan nilai faktor keselamatan 0,184 dan pada kondisi beban gempa sebesar 0,138. Simulasi pemasangan angkur dengan spasi 1,25 m sebanyak 15 buah menghasilkan faktor keamanan di atas 1,0

Penerapan Pendekatan Saintifik melalui Model Pembelajaran Kooperatif Tipe Jigsaw di Kelas X SMA Negeri 9 Palu pada Materi Stoikiometri

This study aims to determine the influence of implementation a scientific approach through cooperative-jigsaw learning model on Stoichiometry to the learning achievement of students in class X at SMAN 9 Palu. The method was a quasi experiment with pretest-posttest control group design. The population was students of class X SMA Negeri 9 Palu, where the sample was class XB as the experimental group (n = 29) and class XA as the control group (n = 27), determined by purposive sampling technique. Data were analyzed using nonparametric statistical Mann-Whitney U-Test analysis. The results showed output “Rank” for the mean value of the experimental class was greater than the control class, 33.14 ˃ 23.52. The output of “Test Statistics”, Sig. 2-Tailed (0,026) ˂ 0.05 and Zcount(-2.23) ˂ Ztable (-1.96), as well as each classical completeness and absorption for experimental class were 79% and 83%, while for the control class were 59% and 75%. This study concluded that scientific approach through cooperative-jigsaw model on Stoichiometry influenced positively to the learning achievement of students in class X at SMA Negeri 9 Palu

Aromacare of Jasmine Increased Sleep Needs in Elderly

Introduction: Sleep disorder is one of the problems that faced by elderly. Progress of sleep change from time to time, sleep patterns during the aging experience different than younger people. Sleep patterns in elderly decreases according with increasing age and degenerative processes that occur in physiological. Aroma of jasmine is the one of method to increase sleep needs, but giving the aroma of jasmine with nursing intervention that called aromacare to reduce sleep disorder is never investigated. Method: This study used quasy experiment pretest and posttest design. The population were elderly with sleep disorder in Tresna Werdha Puspakarma Service Home Elderly Mataram. The samples were recruited using purposive sampling, total samples were 14 respondents, according to inclusion and exclusion criteria. The independent variable was aromacare of jasmine and the dependent variable was sleep in elderly. Data were collected using structure questionnaire. Data were analyzed by using wilcoxon sign rank test and mann whitney test to fulfillment adequacy of sleep based on quantity, paired t test and independent t test to fulfi llment adequacy of sleep on quantity with significance α ≤ 0.05. Result: Result showed that aromacare of jasmine increase of fulfi llment of the need of sleep in quality (p < 0.016) and also effect the need of sleep in quantity (p < 0.001). Discussion: It can be concluded that aromacare of jasmine has significantly effect on sleep need of the elderly. Further research should measure the effect of aromacare of jasmine on fulfillment of the need of sleep with the rate of melatonin and EEG (Electro Encephalo Gram)

Geochemistry and geobarometry of Eocene dykes intruding the Ladakh Batholith

We present further distinguishing characteristics among Eocene dykes found along the Southern margin of the Ladakh batholith (NW-India). Coupled evidence from field structures and Nd-Sr isotope data showed that there are two broad dyke provinces extending over 50 km: between Leh and Tunglung, an 'eastern', ENE-trending family with higher crustal assimilation; between Tunglung and Hemis Shugpachan, the ...postprin
