This study also involves asset growth variables as control variables. The object of the research is all manufacturing sector companies listed on the Indonesia Stock Exchange (IDX), with observation periods ranging from 2008 to 2013 that issued R&D costs in their financial statements. The results showed that firm size had a positive and significant effect on capital structure, sales growth and asset growth had a positive but not significant effect, and the investment opportunity set had a negative and significant effect on capital structure. The effect of business risk on the capital structure is negative but not significant, while the company's size on business risk is negative but does not have a significant effect, sales growth and business risk are positive and have a significant effect, the investment opportunity set and business risks are positive and have a significant effect. The results also prove that business risk variables are not able to mediate the influence of company size, sales growth, and investment opportunity set in increasing corporate funding decisions

Abstract

Abstrak—Antrean merupakan suatu kejadian yang disebabkan karena tingginya frekuensi pelanggan yang datang dan fasilitas pelayanan yang kurang memadahi. Salah satu solusi untuk melakukan perbaikan untuk mengatasi masalah antrean adalah simulasi. Perbaikan dilakukan untuk meningkatkan kepuasan konsumen serta mengurangi lost sales. Perbaikan dalam model usulan yang dibuat adalah dengan penambahan mesin struk otomatis dengan alasan menurunkan utilitas server kasir. Hasil perbandingan model awal dan model baru adalah menurunnya utilitas dua pekerja sebesar 34,11% dan 54,7%. Jumlah konsumen yang telah dilayani juga bertambah dari 58 ke 71 orang, waktu tunggu menurun dari 4,31 ke 0,18 menit. Analisa biaya menunjukan bahwa keuntungan yang dihasilkan meningkat sehingga membuat model usulan layak dilakukan.  Kata kunci:  Antrean, simulasi, McDonald’s Plaza Marina

Cancer is one of the leading causes of death in the world, there were 14.1 million cancer cases and 8.2 million of them cause deaths occurred in 2012. The data from BPJS, in January-June 2014 were reported for outpatient treatment of cancer ranks second with 88.106 the number of cases, while for inpatient ranks 5th, with the number of 56.033 cases. Of the many types of cancer, breast cancer is a common malignancy and a major cause of death in women. Chemotherapy is a cancer treatment using a drug that destroy cancer cells. Anticancer drugs in question are cytotoxic drug (a chemotherapeutic agent) such as taxol, bleomycin, doxorubicin, 5-flurourasil, chlorambucil. The actifity of cytotoxic drug is not selective, because they are either toxic to cancer cells and normal cells. Other treatments that can be used to terapy of cancer is using natural product. Eurycoma longifolia Jack is one plant native of Indonesia which has anti-cancer potential. One of The compounds that have the ability cytotoxic is euricomanone. This study aims to determine Cytotoxic effects of ethyl acetate fraction ethanol extract of Eurycoma longifolia Jack to T47D cancer cells by the method of MTT. The sample used are the roots of Eurycoma longifolia Jack, as much as 500g sample were extracted with ethanol. The extract obtained is then fractionated using ethyl acetate solvent. The fractions obtained tested cytotoxic ability by the method of 3- (4,5 dimetiltiazol -2-yl) - 2,5 diphenyl tetrazolium bromide (MTT) to determine IC50 value. The yield resulting from the extraction process was 2.99% or 14,95 g. ethyl acetate soluble fraction amounted to 19.73% from the totally extract. MTT assay results showed IC50 ethyl acetate fraction of ethanol extract Eurycoma longifolia Jack at 340 µg / ml

Abstract

Nyeri punggung bawah  miogenik berhubungan dengan  stress / strain otot-otot punggung, tendon dan  ligamen  yang  biasanya  ada  bila  melakukan  aktivitas  sehari-hari  secara  berlebihan,  seperti duduk  lama.  Nyeri  bersifat  tumpul,  intensitas  bervariasi  seringkali  menjadi  kronik,  dapat terlokalisir  atau  meluas  sekitar  glutea.  Nyeri  ini  tidak  disertai  parestesi,  defisit  neurologi.  Bila batuk atau bersin nyeri tidak menjalar ke tungkai.Masalah nyeri pinggang yang timbul akibat lama dan sikap duduk menjadi fenomena yang sering terjadi pada mahasiswa saat ini. Lamanya jumlah jam  kuliah  yang  harus  diikuti  mahasiswa  mengakibatkan  aktivitas  mahasiswa  lebih  banyak dihabiskan  dengan  duduk  dibangku  kuliah  saat  mengikuti  proses  perkuliahan.  Penelitian  ini bertujuan  untuk  mengetahui  apakah  ada  hubungan  lama  dan  sikap  duduk  perkuliahan  terhadap keluhan nyeri punggung miogenik pada mahasiswa. Desain penelitian yang dipakai adalah desain korelasi  dengan  jumlah  sampel  54  orang.  Hasil  analisis  data  statistic  parametric  dengan  metode Correlasi  Bivariat  dengan  bantuan  komputer  Program  SPSS  Versi  10    diperoleh  hasil  output terlihat bahwa besar hubungan atau koefisien korelasi (r) antara lama dan sikap duduk perkiliahan terhadap keluhan nyeri punggung bawah miogenik adalah 0,600 dengan nilai probabilitas = 0,000 <  0,05  maka  H0  ditolak  yang  berarti  bahwa  ada  hubungan  lama  dan  sikap  duduk  perkuliahan terhadap  keluhan  nyeri  punggung  bawah  miogenik  pada  mahasiswa.  Sedangkan  besarnya pengaruh dihitung dari koefisien determinasi (r2) yaitu sebesar 0,360 (0,745 x 0,745) atau sebesar 36%. Dengan demikian dapat disimpulkan bahwa ada hubungan yang signifikan antara lama dan sikap duduk terhadap keluhan nyeri punggung miogenik pada mahasiswa. Kata Kunci : Duduk, Nyeri Punggung Bawah Miogenik, Mahasiswa

Abstract

Aortic insufficiency is a condition where the valve can not close completely so that when blood flow to part of diastole the left ventricle. Total amount of blood flow was 50 cc of the contents of sekuncup. Thus if the contents sekuncup 70 cc and 30 cc flowing again, the circulation remained normal for the ventricle must pump 100 cc of blood (70 cc to 30 cc circulation is flowing again). So the left ventricle has to work more normally resulting  in dilatation and hypertrophy.  This resulted  in shortness of  breath,  decreased activity or limited activity,  heavy dependence in performing everyday  activities,  to provide effective and efficient handling,  then conducted an examination method of examination shortness of  breath with Exertion scale,  the  noise  with auscultation.  Things that  can help to reduce the problems  mentioned  above can  be  done by the  method of Breathing Exercise, exercise therapy, early mobilization.  The  purpose of these modalities is to reduce shortness of breath, prevent the complications of bed rest is pneumonia, improving the ability of heart function and increase the tolerance ability of functional activity and restore the  function  of physiological, psychosocial,  work and get back to optimal can tolerate daily activities.
