Abstract

Perakitan sepatu menggunakan perekat atau lem yang mengandung senyawa organik volatil (diantaranya benzena, toluen, dan xylen. Benzena dan metabolitnya terbukti dalam peningkatan stres oksidatif yang terlihat dari peningkatan malondialdehid (MDA). Penelitian ini bertujuan untuk mengindentifikasi konsentrasi benzena di udara tempat kerja dan hubungan antara benzena di dalam tubuh melalui pengukuran biomarker S-Phenylmercapturic Acid (S-PMA) terhadap stres oksidatif melalui pengukuran kadar plasma MDA pekerja bengkel sandal/sepatu. Penelitian ini menggunakan studi cross-sectional pada sepuluh bengkel sandal/sepatu. Jumlah sampel sebanyak 64 pekerja diambil dengan metode total sampling. Hasil penelitian menunjukkan rata-rata konsentrasi benzena di udara empat kerja masih dibawah NAB yang ditentukan oleh Peraturan Menteri Tenaga Kerja No. 13 Tahun 2011 yaitu 0,002066 ppm dan tidak ada hubungan yang signifikan antara konsentrasi S-PMA dalam urin terhadap kadar MDA plasma darah akan tetapi pekerja yang memiliki konsentrasi S-PMA lebih tinggi berisiko 1,31 kali lebih besar memiliki kadar MDA yang lebih tinggi.

Abstract

HIGHLIGHTSInformation on how climate change can shape Calamus javensis distributions is still lackingThe study used SDM with RCP 8.5 scenario for the years 2050 and 2070Suitable habitats for C. javensis are expected to decline by approximately 46.34%Suitable habitats for C. javensis are expected to be concentrated in western parts of West Java ABSTRACTC. javensis is an endemic rattan plant in West Java. While the information on how climate change can shape C. javensis distributions and how C. javensis can cope climate change conditions is still lacking. This information is required considering that C. javensis is an endemic plant in West Java. Then, the purpose of this study is to model the climate change impact on future C. javensis distributions. The study using species distribution modeling (SDM) covering nine locations across West Java with RCP 8.5 climate change scenario for year 2050 and 2070. The result show under the scenarios of climate change, the only appropriate habitats for C. javensis were concentrated in western parts of West Java. Within time series and climate change scenarios, the suitable habitats categorized as very high suitable for C. javensis were estimated to decline. From 2050 to 2070, suitable habitats for C. javensis will decline by around 46.34% from 1025 to 550 km2 in 2070.

Abstract

Disaster risk is formed by the interaction of hazards with a vulnerable community. Risks arising from intentional hazards are generally more predictable than those from natural and technological causes. Therefore, when a hazard is predictable, a disaster can be prevented. On October 1, 2022, a major disaster occurred at Kanjuruhan Stadium, Malang Regency, East Java, Indonesia, following a Liga 1 Indonesia professional football match between Arema FC and Persebaya, resulting in 712 casualties, including 132 fatalities, 96 serious injuries, and 484 minor injuries. Strengthening the police’s role in disaster prevention at stadiums is essential to minimize the likelihood of similar incidents in the future. This study aims to formulate a disaster prevention strategy from the police role perspective from the case study of the 2024-2025 Liga 1 football match between Persija Jakarta and Dewa United at the Gelora Bung Karno Main Stadium (SUGBK) on September 16, 2024. A qualitative approach was applied through interviews and literature review, analyzed using qualitative SWOT analysis and descriptive analysis. The findings show that Polda Metro Jaya conducted a risk assessment in accordance with existing regulations. The study concludes that the risk assessment performed by the Directorate of Vital Object Protection of Polda Metro Jaya for SUGBK was rated good, ensuring the match could proceed safely. Furthermore, the police play an important role in the disaster prevention strategy at SUGBK. However, current regulation only provides guidelines for risk assessment in sports competitions, and do not yet comprehensively address other mass gatherings such as entertainment or religious events.
