Introduction : LVH is an important cardiovascular risk factors in hypertensive patients.Accuracy of ECG criterias was relatively low in diagnosis LVH. Cornell product criteria are the criteria used in the diagnosis LVH in obesity because of easier application. The aim of this study was Determine the accuracy of the Cornell product and sokolow lyon in the detection of left ventricular hypertrophy in obese hypertensive patients at Adam Malik General Hospital.Methods : This cross sectional study from September to October 2015 on 61 cardiology policlinic patients and we did anamnesis, measurement of blood pressure, height, body weight, BMI, BSA, ECG and Echocardiography.Result : From61 patients admitted to cardiology policlinic, we found 34 male and 27 female. The result of echocardiography revealed 38 of hypertensive patients have LVH (62.3%). Sensitivity, specifity and accuracy of different ECG criteria for diagnosis LVH ranged from 31.6% (Cornell product and Romhilt estes) to 47.4% (Cornell Voltage), 65.2%(Cornell Voltage) to 95.8%(Sokolow Lyon), 50% (Cornell Product and Romhilt Estes)to 61.7% (Sokolow Lyon). Positive predictive value were ranged from 75% (Cornell & Romhilt Estes) to 92.9% (Sokolow Lyon) andNegative predictive value were ranged from 42.2%(Cornell Product and Romhilt estes) to 46.8% (Sokolow lyon).Conclusion :The accuracy of ECG criteria Cornell Product no better than lyon Sokolow criteria in terms of assessing LV hypertrophy in hypertensive patients with obesity.Key word : Leftventricular hypertrophy, Cornel product, sokolow lyon, hypertensive obese

Misalkan H adalah graf tak terhubung dan c adalah pewarnaan-k titik pada H yang menginduksi partisi Π = {C1, C2, · · · , Ck} dari V (H). Kode warna dari titik v ∈ V (G) adalah (d(v, C1), d(v, C2), · · · , d(v, Ck)) dengan d(v, Ci) = min{d(v, x)|x ∈ Ci} dan d(v, Ci) < ∞ untuk 1 ≤ i ≤ k. Pewarnaan c dikatakan pewarnaan k-lokasi jika semua kode warna dari semua titik di H berbeda. Bilangan kromatik lokasi dari graf tak terhubung H yang dinotasikan sebagai χ 0 L (H), adalah bilangan bulat terkecil k sedemikian sehingga H mempunyai k-pewarnaan lokasi. Pada tulisan ini akan dibahas bilangan kromatik lokasi graf tak tehubung dengan graf lintasan dan lima graf bintang ganda sebagai komponen-komponennya.Kata Kunci: Bilangan Kromatik Lokasi, Graf tak Terhubung, Graf Lintasan, Graf Bintang Ganda

This study aims to determine financial performance by analyzing the financial statements of PT. Unilever Tbk, listed on the Indonesia Stock Exchange (IDX) for 2017-2021. The data used in this study comes from the company's financial statements in the form of balance sheets and income statements of PT. Unilever Tbk for the period 2017- 2021 using descriptive quantitative research methods. By using the components of financial performance, in this case, related to the ratio of liquidity, profitability, solvency and activity ratios. From the results of the calculation of the financial values of PT. Unilever Tbk shows that the ratios that have met the standards or the ratios are considered good are the solvency ratio, namely the debt to equity ratio; the profitability ratio, namely the return on investment and return on equity; and the ratio activity, namely the ratio of total assets turn over. While the value of the ratio considered not good or the ratio number does not meet industry standards is the Liquidity ratio, namely the current ratio and the quick ratio; solvency is the debt to assets ratio, and activity is the fixed assets turnover ratio.

Pemeliharaan dan penanganan mesin yang tidak tepat dapat menyebabkan menurunnya tingkat produktivitas dan efisiensi mesin. PT XYZ merupakan perusahaan yang bergerak dalam bidang pembuatan Crumb rubber. Permasalahan pada PT XYZ terdapat pada banyaknya downtime yang terjadi pada mesin Creeper serta kurang maksimalnya jumlah produksi yang menyebabkan kurangnya efektivitas total mesin keseluruhan (OEE) pada mesin Creeper. Untuk dapat meningkatkan produktivitas mesin maka perlu diketahui nilai efektivitas mesin perhintungan Overall Equipment Effectiveness (OEE). Faktor yang mempengaruhi dalam perhitungan nilai OEE adalah Availability Ratio, Performance Effeciency Ratio, dan Rate Of Product. Setelah didapatkan nilai OEE maka dapat diidentifikasi penyebab permasalahan yang terjadi dengan menggunakan Fishbone diagram. Hasil penelitian menunjukan bahwa nilai OEE pada mesin Creeper 87,24% nilai efektivitas ini telah memenuhi nilai standar OEE yaitu 85%. Upaya yang dapat dilakukan untuk meningkatkan efektifitas mesin dengan cara Preventive Maintenance secara berkala untuk menjaga performasi mesin.
