Application of the rules safety and healthy such as Law No. 13 of 2003 Article 87 should be able to protect the rights of labor safety in performing the work to increase production and productivity.

The purpose of this study is to identify the increase in worker productivity and the factors that affect productivity in the implementation of research safety and healthy.

Metode used in this study is a survey method whereby the data collection interview method is used, for the processing of research data used in the calculation of productivity, namely the work result / working time.

The conclusion, time obtained is the implementation of rule safety and healthy in the project affect worker productivity and the factors that affect worker productivity is human resources, equipment, working methods, and environmental conditions."

"ABSTRAKTujuan: Mengetahui batasan nilai PSA untuk memprediksi adanya metastasis tulang pada pasien kanker prostat di RS Sardjito. Metode: Penelitian retrospektif, dengan mengumpulkan rekam medis pasien kanker prostat telah dilakukan bone scintigraphy di RS Sardjito tahun 2006 - 2011.Hasil: Dari 83 pasien kanker prostat yang telah dilakukan bone scintigraphy, terdapat 55 pasien (66%) mengalami metastasis tulang dan terdapat 28 pasien (34 %) yang tidak mengalami metastasis tulang. Dari 55 pasien yang mengalami metastasis tulang, terdapat 11 pasien (20 %) dengan PSA kurang dari 20 ng/ml dan terdapat 44 pasien (80 %) yang memiliki PSA lebih dari 20 ng/ml. Cut-off point PSA 17.65 ng/ml memiliki sensitivitas terbesar yaitu 85.5% dan spesifisitas 53.6%.Kesimpulan: Pemeriksaan bone scintigraphy dianjurkan pada pasien dengan PSA > 17.65 ng/ml, sedangkan pada pasien dengan PSA < 17.65 dianjurkan pada pasien dengan gejala klinis nyeri tulang.

ABSTRACTObjective: Prostate cancer shows a strong predilection to spread to the bones, with bone metastases identified at autopsy in up to 90 % of patients dying from prostate cancer. Serum prostate specific antigen (PSA) concentration has been widely applied as a biomarker to diagnose and monitor prostate cancer. Technetium-99m methylene diphosphate (Tc—99m MDP) whole body bone scintigraphy is currently a well-accepted diagnostic procedure for bone metastasis in malignancy. The aim of this study was to establish a useful serum PSA cut-off value to predict the presence of bone metastasis in men with prostate cancer. Material and Methods: Consecutive male patients diagnosed with prostate cancer were retrospectively analyzed. All of the subjects had received Tc-99m MDP whole body bone scintigraphy and had their serum PSA concentration measured at Sardjito Hospital, Yogyakarta. The proper cut-off value was established based on statistical analysis in order to predict the possibility of bone metastasis among prostate cancer patients.Results: In total, 83 consecutive male patients with prostate cancer were enrolled, and 55 patients (66 %) were confirmed by scintigraphic findings to have bone metastases. A serum PSA concentration of 17,65 ng/ml gave the best sensitivity (78,33 %) and specificity (65,21 %). The positive predictive value, negative predictive value were 85,45 % and 53,57 %, respectively (p<0,05).Conclusion: A cut-off value of 17,65 ng/ml appears to be an appropriate benchmark for stratifying metastatic bone disease in prostate cancer patients at Sardjito Hospital, Yogyakarta, such that if a patient with newly diagnosed prostate cancer and without any skeletal symptoms has a serum PSA concentration of less than 17,65 ng/ml,we suggest that they would not need to undergo bone scintigraphy."

"ABSTRAKMetode Magnetotellurik MT merupakan metode geofisika yang cukup efektif untuk memetakan kondisi distribusi resistivity bawah permukaan dengan baik, khususnya pada sistem panas bumi. Namun, metode ini sangat sensitif terhadap noise. Noise tersebut bisa timbul akibat aktivitas mekanik seperti vibrasi dan aktivitas kelistrikan seperti aliran listrik pada powerline yang berada didekat titik pengukuran. Untuk mengeliminasi noise ini digunakan filter digital yang terdiri dari despike filter dan notch filter. Despike filter digunakan untuk mengeliminasi spike noise yang bersifat irreguler, sedangkan notch filter untuk harmonic powerline noise yang bersifat reguler. D dapat digunakan pada data impedansi MT. Filter ini dibangun dalam program MTFilter yang dapat mengolah dan memfilter data time series MT hingga didapatkan kurva resistivitas dan fase dalam domain frekuensi. Hasil pengolahan data dan inversi menunjukan bahwa teknik pengeliminasian noise menggunakan filter digital ini dapat meningkatkan kualitas data.

ABSTRACTMagnetotelluric MT method is known as effective geophysical method to mapping the condition of the subsurface resistivity distribution, especially in the geothermal system. However, this method is very sensitive to noise. The noise can occur due to mechanical activity such as vibration and electrical activity such as powerline electric current near the point of measurement. To eliminate this noise is used digital filter consisting of despike filter and notch filter. Despike filters are used to eliminate irregular spike noise, while the notch filters for harmonic powerline noise are regular. D can be used on MT impedance data. This filter is built into MTFilter program which can process and filter the time series data of MT to get the resistivity and phase curve in the frequency domain. The result of data processing and inversion shows that noise elimination technique using digital filter can improve data quality."

"ABSTRAKTujuan penelitian untuk menganalisis implementasi kebijakan tntang standar tarifINA-CBGs program JKN. Penelitian ini menggunakan metode kualitatif denganmelakukan wawancara mendalam. Informan penelitian melibatkan aktor pemangkukepentingan antara lain Pusat Pembiayaan Jaminan Kesehatan P2JK KementerianKesehatan, BPJS Kesehatan, asosiasi profesi, dan asuransi kesehatan swasta. Hasilpenelitian menunjukkan bahwa RS swasta merupakan pihak yang belum siap dalammelakukan implementasi kebijakan tarif INA-CBGs karena besaran tarif dirasakanbelum mencukupi beban operasional dan pemeliharaan sarana dan prasarana RS.Setiap aktor pemangku kepentingan telah memiliki agenda sendiri dalam rangkamembuat implementasi kebijakan tarif INA-CBGs menjadi semakin lebih baik,termasuk IDI yang mempersiapkan standar mutu pelayanan medis untuk diusulkanke Kemenkes. Penelitian ini menyimpulkan bahwa kebijakan tarif INA-CBGsmemerlukan perumusan yang ke arah lebih baik.

ABSTRACTThe purpose of this research is to analyze the implementation of INA CBGs tariff policy of JKN program. This research used qualitative method by conducting in depth interview. The research informants involved stakeholder actors such as Center of Health Financing and Insurance P2JK Ministry of Health, BPJS Health, professional associations, and private health insurance. The results showed that private hospitals were not ready in implementing the tariff policy of INA CBGs because the tariff is not sufficient to meet the operational and maintenance expense of hospital facilities and infrastructure. Each of stakeholder has iown agenda in order to improve the implementation of t he INA CBGs tariff policy, including IDI preparing the quality standard of medical services that should be proposed to the Ministry of Health. This research concluded that INA CBGs tariff policy requires better formulation. The Ministry of Health should consider increasing the INA CBGs tariff as per the expectations of professional organizations and prepare thecalculation of CBGs based on performance. "
