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: Faktor Penentu Partisipasi Asuransi Pengangguran: Penerapan Theory of Planned Behaviour
Abstrak: Unemployment is one of the economic disorders that affect the economic growth rate. The recent pandemic outbreak has turned the medical crisis into a global financial downturn, threatening the health and employment of people around the world. Unemployment insurance is intended to assist workers with partial and momentary income replacement, access to skill training, and job placement assistance during their unemployment period. The scheme was launched in Indonesia on March 2021. This study analyzed the intention effect toward participation and the effect of attitude, subjective norms, and perceived behavioral control towards the intention to participate using the Theory of Planned Behaviour. The study used 200 participants of BPJS Ketenagakerjaan in the DKI Jakarta regional office as respondents. Binary logistic regression and SEM analysis are used in this study. The result showed that intention significantly affects participation in unemployment insurance. Attitude toward behavior, subjective norms, and perceived behavioral control positively and significantly influence the intention to participate. Subjective norm is significant as an intervening variable between attitude and perceived behavioral control toward the intention to participate. Thus, strategies focusing on these factors can increase participation in the unemployment insurance scheme.

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.
