Judul: Faktor Penentu Program Kembali Bekerja (RTW) untuk Karyawan Kecelakaan Kerja di Indonesia
Abstrak: Work accidents can determine the quality of safety in the workplace, which contributes to national economic development. It is estimated that GDP losses from work injuries are 3.94% annually. Globally, 374 million non-fatal work accidents and 2.78 million people died related to work injuries. Asia Pacific region is the highest work injury compared to other regions worldwide, with 1.1 million deaths. The region contributes the highest work injury from South-East Asia. Indonesia is the most fatal injury, which 15.973 fatal accidents per 100.000 workers (20.9%). It is essential to reactivate work-injured persons to be productive. This study aims to examine the RTW rate, analyze the internal and external factors in the RTW program, and estimate factors affecting the probability of the RTW program for the work-injured employee. The RTW participant data were obtained from BPJS Ketenagakerjaan, with 195 participants following this program due to fatal work injuries in 2020-2021. This study is a cross-sectional and quantitative approach. The RTW rate uses the calculation of the RTW patient. The crosstabulation is used to analyze the RTW's internal and external factors. The logistic regression model estimates the factors affecting the probability of the RTW for a work-injured employee. The result is 75.90% of participants could work after following this program. The participant dominated by younger age (18-29 years), lower working years (0-5 years), male (86%), upper limb amputation (55%), work in the secondary sector (63%), paying a lower rate of insurance (51%), and having work accident in the workplace area (68%). The factor positively influences the success of the RTW program, such as lower and upper amputation (OR=2.474), working in the secondary sector (OR=2.409), following the RTW program in 2020 (OR=2.184), and paying a lower insurance premium rate (OR=3.260). The rate of the RTW in Indonesia is relatively high, with more than three-quarters of participants able to work. Several groups need more attention by providing information about the work environment and road hazards. This finding can be a reference for developing the RTW program to increase the assistance to high-risk patients for not able to work after the RTW program.

Judul: Analisis Risiko Kesehatan dan Keselamatan Kerja di Modern Rice Milling Plant (MRMP) Karawang dengan Pendekatan HIRARC
Abstrak: Implementasi Kesehatan dan Keselamatan Kerja (K3) menjadi penting bagi industri untuk melindungi kesehatan dan keselamatan pekerja, meningkatkan produktivitas, serta mencegah biaya terkait kecelakaan kerja. Penelitian ini bertujuan mengidentifikasi, menganalisis, dan menyusun tindakan pengendalian risiko di MRMP Karawang dengan menggunakan pendekatan Hazard Identification, Risk Assessment, and Risk Control (HIRARC). Potensi bahaya yang telah diidentifikasi berjumlah 26 yang dikelompokkan dalam jenis potensi bahaya mekanik, fisika, kimia, biologi, dan ergonomi. Risiko yang telah teridentifikasi sejumlah 30 yang kemudian dinilai dengan metode semi-kuantitatif berdasarkan pedoman AS/NZS 4360:2004. Tingkat risiko paling prioritas untuk ditindaklanjuti adalah kategori High Risk yaitu kebakaran yang disebabkan korsleting listrik ataupun bara abu burner dan terjatuh dari ketinggian silo. Pengendalian risiko yang digunakan paling banyak mengenai pengendalian administratif, yaitu terkait penerapan prosedur kerja yang aman dan sehat di setiap area kerja, serta penggunaan Alat Pelindung Diri (APD) yang sesuai., The implementation of Occupational Health and Safety (OHS) is crucial for industries to protect the health and safety of workers, enhance productivity, and prevent costs associated with workplace accidents. This study aims to identify, analyze, and develop risk control measures at MRMP Karawang using the Hazard Identification, Risk Assessment, and Risk Control (HIRARC) approach. A total of 26 potential hazards were identified, categorized into mechanical, physical, chemical, biological, and ergonomic hazards. A total of 30 identified risks were assessed using a semi-quantitative method based on the AS/NZS 4360:2004 guidelines. The highest priority risks for mitigation were classified as High Risk, which included fire caused by electrical short circuits or Burner ash embers, and falls from the height of the silo. The predominant risk control measures were administrative controls, particularly the implementation of safe and healthy work procedures in every work area, and the use of appropriate Personal Protective Equipment (PPE).

Judul: Hydrothermal Synthesis of Biphasic Calcium Posphate
Abstrak: Biphasio calsium phosphate (BCP), which was a mixture of hydroxypatite (HA) and tricalcium phosphate (TCP), was synthesized by hydrothermal method followed by sintering process. Hydroxyapatite was produced by using natural calcium source CaO from hen's eggshell and (NH4)2HPO4 as phosphate souce, other hydroxyapatite sample was produce by using synthetic calcium source Ca(OH) and H3PO4 as phosphate source.
