Penerapan Algoritma Apriori untuk Menemukan Hubungan Data Murid dengan Nilai Sekolah
Murid merupakan salah satu komponen terpenting dari sebuah sekolah, karena tanpa adanya murid maka sekolah tidak dapatmelaksanakan kegiatan pembelajaran. Setiap murid pada sebuah sekolah memiliki data yang didapatkan pada saat awalmasuk dan juga nilai sekolah yang merupakan hasil pembelajaran. Namun, data-data tersebut belum diketahuiketerhubungannya sehingga dibutuhkan sebuah metode untuk mengolahnya. Melalui penelitian ini, sebuah metode DataMining yaitu Association dengan Algoritma Apriori digunakan untuk mencari hubungan antara data murid dengan nilaisekolah. Data murid merupakan data awal masuk murid yang terdiri dari tempat dan tahun lahir, agama, dan tahun masuk.Nilai minimal support yang digunakan sebesar 20% dan nilai confidence merupakan parameter yang menentukan seberapabesar hubungan antara data murid dengan nilai sekolah. Nilai confidence terbesar diperoleh dari hubungan antara agamaKristen dengan nilai sekolah ↑77-82 sebesar 54,5%. Penelitian ini dilakukan pada SD Kristen Kalam Kudus IV Alam Raya
Chiral aspects of hadron structure
Chiral loop corrections for hadronic properties are considered in a
constituent quark model. It is emphasized that the correct implementation of
such corrections requires a sum over intermediate hadronic states. The leading
non-analytic corrections are very important for baryon magnetic moments and
explain the failure of the sum rule
predicted by the
constituent quark model.Comment: 10 pages, latex, 2 ps figures, to appear in Phys. Lett.
Sex-Specific Effects of Respiratory Muscle Endurance Training on Cycling Time Trial Performance in Normoxia and Hypoxia.
Objectives: We tested the hypotheses that respiratory muscle endurance training (RMET) improves endurance cycling performance differently in women and men and more so in hypoxia than in normoxia. Design: A prospective pre-post cross-over study with two testing conditions. Methods: Healthy and active women (seven, 24 ± 4 years, mean ± standard deviation [SD]) and men (seven, 27 ± 5 years) performed incremental cycling to determine maximum oxygen consumption (VO <sub>2peak</sub> ) and power output (W <sub>peak</sub> ) and on different days two 10-km cycling time trials (TTs) in normoxia and normobaric hypoxia (FiO <sub>2</sub> , 0.135, ~3,500 m equivalent), in a balanced randomized order. Next they performed supervised RMET in normoxia (4 weeks, 5 days/week, 30 min/day eucapnic hyperpnea at ~60% predicted maximum voluntary ventilation) followed by identical post-tests. During TTs, heart rate, ear oximetry reading, and W <sub>peak</sub> were recorded. Results: The VO <sub>2peak</sub> and W <sub>peak</sub> values were unchanged after RMET. The TT was improved by 7 ± 6% (p < 0.001) in normoxia and 16 ± 6% (p < 0.001) in hypoxia. The difference between normoxic and hypoxic TT was smaller after RMET as compared with that before RMET (14% vs. 21%, respectively, p < 0.001). All effects were greater in women (p < 0.001). The RMET did not change the heart rate or ear oximetry reading during TTs. Conclusion: We found a greater effect of RMET on cycling TT performance in women than in men, an effect more pronounced in hypoxia. These findings are congruent with the contention of a more pronounced performance-limiting role of the respiratory system during endurance exercise in hypoxia compared with normoxia and more so in women whose respiratory system is undersized compared with that of men
Unexpected Effect of Internal Degrees of Freedom on Transverse Phonons in Supercooled Liquids
We show experimentally that in a supercooled liquid composed of molecules
with internal degrees of freedom the internal modes contribute to the frequency
dependent shear viscosity and damping of transverse phonons, which results in
an additional broadening of the transverse Brillouin lines. Earlier, only the
effect of internal modes on the frequency dependent bulk viscosity and damping
of longitudinal phonons was observed and explained theoretically in the limit
of weak coupling of internal degrees of freedom to translational motion. A new
theory is needed to describe this new effect. We also demonstrate, that the
contributions of structural relaxation and internal processes to the width of
the Brillouin lines can be separated by measurements under high pressure
Renormalization Group Study of the soliton mass on the (lambda Phi^4)_{1+1} lattice model
We compute, on the model on the lattice, the soliton
mass by means of two very different numerical methods. First, we make use of a
``creation operator'' formalism, measuring the decay of a certain correlation
function. On the other hand we measure the shift of the vacuum energy between
the symmetric and the antiperiodic systems. The obtained results are fully
compatible.
We compute the continuum limit of the mass from the perturbative
Renormalization Group equations. Special attention is paid to ensure that we
are working on the scaling region, where physical quantities remain unchanged
along any Renormalization Group Trajectory. We compare the continuum value of
the soliton mass with its perturbative value up to one loop calculation. Both
quantities show a quite satisfactory agreement. The first is slightly bigger
than the perturbative one; this may be due to the contributions of higher order
corrections.Comment: 19 pages, preprint DFTUZ/93/0
Rumah Sakit Khusus Jantung Di Kota Batu
Penyakit Jantung menjadi salah satu pembunuh terbesar dalam beberapa tahun terakhir baik di Indonesia maupun di dunia. Khususnya di daerah Malang Raya, lebih dari 34% dari jumlah pasien yang berobat di Rumah Sakit se-Malang Raya merupakan penderita penyakit jantung pada tahun 2011. Dalam menanggapi hal ini, Pemerintah Kota Batu berencana membangun Rumah Sakit Khusus Jantung di Kota Batu, tepatnya di Tlekung, daerah Jalan Hassanudin. Rumah Sakit Khusus Jantung di Kota Batu, dirancang berdasarkan standar operasional pelayanan penyakit jantung, dimulai dari tata letak antar intalasi, sampai ke waktu tempuh yang dijadikan acuan dalam merencanakan alur sirkulasi pada rumah sakit khusus jantung. Sirkulasi menjadi penting dalam perancangan rumah sakit khusus jantung, karena kebutuhan akan kecepatan penanganan pada penyakit jantung menjadi hal utama yang harus di perhatikan. Oleh karena itu, sirkulasi menjadi poin utama dalam perancangan rumah sakit khusus jantung di Kota Batu
