"[Pajanan debu bedak talk (talcum powder) adalah salah satu kontaminan yang dapat menyebabkan gangguan fungsi paru baik obstruktif, restriktif maupun campuran pada karyawan di tempat kerja. Tujuan penelitian adalah untuk mempelajari hubungan antara pajanan debu respirable talcum powder dengan gangguan fungsi paru dan keluhan subyektif karyawan di PT.XYZ tahun 2015. Penelitian ini menggunakan metode survei yang dilakukan tanpa intervensi, yang bersifat analitik dengan rancangan cross sectional. Besar sampel sebanyak 18 daripopulasi 42 orang yang diambil secara purposive sampling. Variabel yang diamati adalah tingkat pajanan debu respirable talcum powder pada karyawan, umur, lama bekerja, kebiasaan merokok, kebiasaan olah raga, riwayat penyakit paru dan penggunaan APD. Jenis data adalah data primer dan sekunder, dan pengumpulan data dari hasil pengukuran debu, pemeriksaan spirometri, foto thorax, hasil kuesioner dan wawancara responden. Analisis data yang digunakan adalahanalisis univariat, bivariat dan multivariat. Hasil penelitian menunjukan bahwa ada hubungan yang signifikan antara pajanan debu respirable bedak talk dengan keluhan subyektif hidung tersumbat, sakit tenggorokan dan batuk (p<0,05) dan ada hubungan antara kebiasaan merokok dengan sakit tenggorokan dan penggunaan APD dengan keluhan hidung tersumbat dan sakit tenggorokan. Hasil analisis regresi logistik dari tiga variabel pajanan debu bedak talk, kebiasaan merokok dan tidak menggunakan APD menunjukkan bahwa merokok variabelpaling dominan dan beresiko 25 kali mengalami keluhan sakit tenggorokan dibandingkan dengan yang tidak merokok. Disarankan untuk memperbaiki instalasi Local Exhaust Ventilation pada proses bedak, pemantauan dan pengukuran debu bedak talk secara rutin, MCU secara berkala, program promosi kesehatan di tempat kerja, penyediaan APD bagi karyawan dan pelatihan tentang penggunaan dan perawatannya.;Talcum dust (powder) exposure is one of particulate contaminant that can cause pulmonary function disorder either obstructive, restrictive or combination. The research aimed to learn the correlation between respirable dust of talcum exposure with pulmonary function disorder and health subjective complaint from exposedemployees in PT. XYZ, 2015. The research was analytical study with cross sectional design using survey method without any intervention. There were 18 samples from 42 employee of total population by purposive sampling. The observed variables were respirable dust of talcum exposure to employees, age, work length, smoke habits, exercise habits, history of pulmonary disease and PPE usage. The data were generated from primary and secondary data, and collectedfrom respirable dust measurement, pulmonary examination (spirometry test and photo thorax), questionnaires and interview. The data was analyzed by univariate, bivariate and multivariate. The research showed that there was significantly correlated between respirable dust of talcum powder exposure with health subjective complaint of nasal congestion, sore throat and cough (p<0,05) and there was correlation between smoke habits with sore throat and PPE usage with nasal congestion and sore throat. The multiple logistic regression analysis from three variables i.e. respirable dust of talcum powder exposure, smoke habits and PPE usage showed that smoker among employees was the most dominant factor and had risk until 25 times induced health subjective complaint compared with non-smokers. It is recommended to improve Local Exhaust Ventilation for talcumpowder process, periodically Medial Check Up, health promotion program, PPE provision and PPE training to employees.;Talcum dust (powder) exposure is one of particulate contaminant that can causepulmonary function disorder either obstructive, restrictive or combination.

"Polipropilena (PP) merupakan salah satu jenis polimer termoplastik yang dibuat oleh industri polimer hulu dan digunakan dalam berbagai aplikasi. Pada penggunaannya, PP banyak ditambahkan material lain (contoh: talcum) untuk meningkatkan kualitas dan memperbaiki sifat materialnya sesuai kebutuhan. Di Indonesia, PP merupakan salah satu material yang memiliki permintaan yang besar. Namun permintaan tersebut tidak diimbangi dengan produksi yang dilakukan oleh industri polimer hulu yang ada di dalam negeri. Pada tahun 2011, Indonesia menjadi negara pengimpor produk olefin terbanyak di ASEAN. Oleh karena itu, solusi alternatif diperlukan untuk mengatasi masalah ini, salah satunya dengan menggunakan material daur ulang (regrind). Studi ini dilakukan untuk mengkaji karakteristik paduan yang terbentuk dari material regrind polipropilenatalcum (jenis komposit polipropilena yang banyak digunakan dalam industri otomotif) sehingga dapat diketahui apakah material regrind memiliki karakteristik yang tidak kalah baik dibandingkan material fresh-nya. Studi ini didukung dengan sebuah fakta bahwa material regrind polipropilena-talcum 20% memiliki titik leleh yang tidak berbeda jauh dengan temperatur leleh polipropilena (sekitar 176 °C), yaitu pada temperatur 176.4 °C. Studi ini dilakukan dengan membentuk paduan dari material regrind polipropilena-talcum 20% dan 30% dan melalui proses dry mixing dan hot melt mixing. Karakteristik yang dikaji meliputi perubahan morfologi yang terjadi akibat proses regrinding dan pencampuran material, perilaku mekanik (kekuatan tarik dan modulus elastisitas), dan perilaku termal material tersebut.

Polypropylene (PP) is a thermoplastic polymer made by the polymer industry and used in various applications. In the application, PP is added to other material (eg, talcum) to improve the quality and enhance the properties of material. In Indonesia, the PP is one of the materials that have a great demand. But the request is not matched by production undertaken by the existing polymer industry in the country. In 2011, Indonesia became a net importer of most olefin products in ASEAN. Therefore, an alternative solution is needed to solve this problem, such as using recycled materials (regrind).

This study was conducted to examine the characteristics of the alloy is formed from polypropylene-talcum regrind material (polypropylene composites are widely used in the automotive industry) to know whether regrind material characteristics has significant differences compared to the fresh material. This study was supported by the fact that regrind material polypropylene-talcum 20% has a melting point which is not much different from the polypropylene melting temperature (around 176.0 °C), which is at 176.4 °C.

This study was conducted to form alloys of polypropylene regrind material-talcum 20% and 30% and through the process of dry mixing and hot melt mixing. Characteristics examined include morphological changes that occur due to the regrinding and mixing materials, mechanical behavior (tensile strength and modulus of elasticity), and the thermal behavior of the material."

The aim of this study is to identify and understand the requirements and testing of drug substances in the three pharmacopoeias. The method used is a comparison of the testing parameters contained in the monographs of drug substances in the three pharmacopoeias using Microsoft Excel. The results show that there are some similarities and differences in the requirements and testing of drug substances in the three pharmacopoeias. In conclusion, despite some differences, the three pharmacopoeias provide clear guidelines on the testing and quality requirements of drug substances used in Indonesia."
