"ABSTRAKNowadays cloud computing is one of the most popular processing models. More and more different kinds of workloads have been migrated to clouds. This trend obliges the community to design algorithms which could optimize the usage of cloud resources and be moreefficient and effective. The paper proposes a new model of workload allocation which bases on the complementarity relation and analyzes it. An example of a case of use is shown and an increase in the workload execution is presented."

"Penelitian pada 2 lokasi di area PT Antam (Persero) Tbk UBPP Logam Mulia yang terdiri atas area Peleburan dan Pemurnian Perak menunjukkan indeks WBGT indoor antara 29.8℃ sampai dengan 32,25℃. Setelah dilakukan analisis indeks WBGT, beban kerja dan pola kerja berdasarkan Permenaker No. 13 Tahun 2011, didapatkan hasil bahwa dari 23 responden yang menjadi subyek penelitian, 22 responden (95,7%) termasuk kelompok berisiko mengalami pajanan tekanan panas. Seluruh responden (100%) merasakan temperatur lingkungan tempat mereka bekerja panas serta 70% responden merasa tidak nyaman (terganggu) dengan kondisi tersebut. Seluruh responden yang menjadi subyek penelitian pernah mengalami keluhan akibat pajanan tekanan panas tetapi dengan frekuensi yang berbeda-beda. Berdasarkan keluhan-keluhan yang dirasakan responden didapatkan bahwa 78,3 % responden mengalami gejala Heat Exhaustion, 17,4% responden mengalami gejala Heat Cramps, dan 4,3% Responden mengalami Heat Rash. Dan jenis keluhan yang sangat sering (setiap hari) dirasakan pekerja adalah banyak mengeluarkan keringat (78,3%) dan merasa cepat haus (69,6%), sedangkan jenis keluhan yang hampir tidak pernah dirasakan oleh pekerja adalah merasa ingin pingsan (78,3%).

Research on 2 location at PT Antam (Persero) Tbk UBPP Precious Metal consisting of Smelting Area and Silver Refining Area show WGBT index indoor 29.8℃ until 32,25℃. After WGBT index analysis, workloads and work pattern based on Permenaker No. 13 Tahun 2011, from 23 respondents who become subject of this research showed result 22 respondents (95,7%) belong to group which have a risk to get heat pressure exposure. All respondents (100%) feel temperatures on their work environment so hot and 70% respondents feel not uncomfortable (annoyed) with that condition. All respondent on this research had complaints due to heat pressure exposure with different frequency.

Based on respondents complains show that 78,3 % respondents get symptom Heat Exhaustion, 17,4% respondents get symptom Heat Cramps, and 4,3% respondents get symptom Heat Rash. The most complaint (everyday) felt by worker are worker always sweating (78,3%) and get thirsty easily (69,6%), other complaints which almost never felt by worker is faint (78,3%)."
