The construction sector is ranked first as the most dangerous occupation in the world and is an area with a high risk of occupational accidents. According to BPJS Ketenagakerjaan data in 2019, cases of work accidents in Indonesia 2017 increased in 2018. The purpose of this study was to determine the relationship between age, OHS knowledge, OHS supervision, unsafe act, and unsafe condition for building construction project workers at PT. X. This research was quantitative study with a cross-sectional study design. The sampling technique used simple random sampling where the sample amounted to 109 workers. The results of the research analysis using the chi-square statistical test showed that the variables of age (p-value = 0,662), OHS knowledge (p-value 0,003), OHS supervision (p-value 0,001), unsafe act (p-value 0,002), unsafe condition (p-value 0,000) with a significance limit of α = 0,05. It can be concluded that there is an associated between OHS knowledge, OHS supervision, unsafe act, and unsafe condition with work accidents and there is no associated between age with work accidents. It is recommended that companies provide education to workers in the form of providing OHS knowledge through the toolbox meeting program and periodically monitoring of conditions in the work field.

Tujuan penelitian ini menganalisis hubungan lingkungan kerja dengan gejala Sick Building Syndrome pada pegawai BPJS Kesehatan Kota Depok tahun 2019. Penelitian menggunakan metode kuantitatif dengan desain studi cross sectional. Sampel dalam penelitian ini berjumlah 70 orang pegawai BPJS Kesehatan Kota Depok. Variabel lingkungan fisik diperoleh berdasarkan hasil pengukuran lingkungan, sedangkan variabel lingkungan non fisik dan karakteristik individu menggunakan kuesioner. Analisis data menggunakan uji Chi Square dan uji Fisher’s Exact. Hasil penelitian menunjukkan terdapat hubungan antara pencahayaan (p=0,001), umur (p=0,006), kondisi psikososial (0,025), kebiasaan merokok (p=0,025), dan riwayat penyakit (p=0,038) dengan gejala SBS. Variabel yang tidak berhubungan dengan gejala SBS adalah iklim kerja (p=0,191), hubungan kerja pegawai dan atasan (p=0,447), hubungan kerja antar pegawai (p=1,000), jenis kelamin (p=0,506), dan masa kerja (p=1,000). Gejala SBS yang paling banyak adalah kantuk.

The furniture industry was one of many industries that are necessities part of human life. The purpose of this study was to analyze the relationship between age, length of work, hours of work, OSH knowledge, unsafe action, and unsafe condition with workplace accidents in furniture industry workers in the Duren Sawit Subdistrict in 2020. The method used in this study was a quantitative analysis method with a cross-sectional study design. The sample in this study were 57 workers. The result obtained using the chi-square test was the variable age, hours of work, and unsafe condition found the value of p-value>0,05 or there was not any relationship. The variable length of work, OSH knowledge, and unsafe action obtained value of p-value<0,05 or there was a relationship. The recommended action for workers and shop owners is to increase awareness in using PPE when working, always maintain cleanliness and implement OSH behavior in the workplace, always obey the rules and remind each other if there are workers who do not obey the rules, and always maintain tidiness at the place and make workplace cleaning efforts more routine.

One of the photokeratitis risk factors is acute reversible radiation of ultraviolet (UV) rays, which injure the cornea's epithelial tissue. Informal welding workers are susceptible populations to UV rays exposure. This study aimed to confirm the influence of UV radiation exposure on photokeratitis complaints in welding workers in Cimanggis, Depok, West Java. A cross-sectional study was conducted from February to June 2019 and used to select 100 welding workers purposively. A semi-structured questionnaire was used to determine photokeratitis complaints, age, education level, eye protection, safety knowledge, and work period; the UV radiation measured by A UV meter. Data were analyzed using a logistic regression test. We found the proportion of photokeratitis to be 84.0%, with 76.0% of UV radiation exceeding the Threshold Limit Values (TLV). The logistic regression test showed a significant effect of UV radiation on photokeratitis after controlling confounding variables (education level, eye protection, safety knowledge, and welding distance) (p-value = 0.006; AdjOR = 7.236; 95% CI: 1.74–30.07). It can be concluded that UV radiation, more than TLV, constitutes the primary risk factor for photokeratitis complaints. Risks for photokeratitis were influenced by low education level, poor eye protection, limited safety knowledge, and welding distance ≤ 45 cm.

An initial survey that had been done  found that the location of the settlement where residents of cipayung lived was very close to the location of the Cipayung Landfill.
