Seiring dengan target pemerintah dalam peningkatan produksi minyak dan gas di lepas pantai, maka penggunaan bahan kimia dalam kegiatan produksi minyak dan gas semakin meningkat, hal ini memunculkan kekhawatiran akan potensi permasalahan kesehatan pekerja, oleh karenanya perlu dilakukan kajian risiko kesehatan. Penelitian ini bertujuan untuk menganalisis tingkat risiko (risk rating/RR) kesehatan terkait pajanan dari kesebelas bahan kimia utama yang digunakan pekerja, pada proses produksi minyak dan gas di kapal FPSO XYZ tahun 2022. Metode Chemical Risk Assessment (CRA) yang digunakan adalah Stoffenmanager® 8 version 5.0 yang merupakan tools untuk menilai risiko kesehatan jalur pajanan inhalasi dan dermal dari penanganan enam bahan kimia oleh production technician di area kerja topside deck dan lima bahan kimia oleh utility operator di area kerja machinery deck. Hasil CRA menunjukkan bahwa tingkat risiko (RR) jalur inhalasi dimana satu bahan kimia kategori risiko tinggi (1,highest) delapan bahan kimia kategori risiko sedang (2, medium), dan dua bahan kimia risiko rendah (3, lowest). Sedangkan berdasarkan risk characterization ratio (RCR) pajanan inhalasi, ada dua bahan kimia yang diketahui nilai RCR task ≥ 1, yang berarti perkiraan konsentrasi emisi yang dihasilkan saat beraktivitas (task concentration estimation/TCE) terhadap potensi bahaya terhirup oleh production technician dan utility operator saat beraktivitas pada jarak yang dekat dengan sumber emisi, dikategorikan berbahaya atau risiko tidak dapat di tolerir (Unacceptable risk). Untuk tingkat risiko dermal efek lokal (skin local), sembilan bahan kimia masuk kategori risiko tinggi dan dua bahan kimia masuk kategori risiko sedang. Sedangkan tingkat risiko dermal efek sistemik (skin uptake), empat bahan kimia kategori risiko sedang, dan tujuh bahan kimia kategori risiko rendah. Hasil risk rating (RR) menentukan pula prioritas tindakan (Action Priority/AP) pengendalian risiko kesehatan. Rekomendasi pengendalian adalah menurunkan tingkat bahaya (HR) dengan melakukan penggantian bahan kimia (subtitusi) dengan bahan kimia yang lebih rendah tingkat bahayanya bagi kesehatan, dan untuk pajanan dermal (ER), otomatisasi proses penanganan, modifikasi teknik pekerjaan dengan membuat sistem penambahan bahan kimia secara gravitasi, menurunkan jumlah dosis pemakaian namun tetap efektif efisien (workplace-related modifiers), mengurangi waktu dan frekuensi penggunaan bahan kimia tersebut (activity time), penambahan ventilasi lokal (LEV) selain ventilasi mekanik, serta menggunakan baju khusus tahan kimia beserta sarung tangannya atau Chemsuit (control measures modifiers). ......Along with the government's target to increase offshore oil and gas production,  the use of chemicals in oil and gas production activities tends to increase, this raises concerns about potential health problems for workers, therefore it is necessary to conduct a chemical health risk assessment. This study aims to analyze the health risk rating (RR) related to exposure to the eleven main chemicals used by workers in the oil and gas production process on the FPSO XYZ ship in 2022. The Chemical Risk Assessment (CRA) method that is used is Stoffenmanager® 8 version 5.0 which is a tool to assess the health risks of inhalation and dermal exposure lines from the handling of six chemicals by production technicians on the topside deck work area and five chemicals by utility operators on the machinery deck work area. The results of the CRA show that the risk level (RR) for the inhalation route is one chemical in the high-risk category (1,highest), eight chemicals in the medium risk category (2, medium), and two chemicals in the low-risk category (3, lowest). Meanwhile, based on the risk characterization ratio (RCR) of inhalation exposure, there are two chemicals whose RCR task value is ≥ 1, which means the estimated concentration of emissions produced during the activities (task concentration estimation/TCE) against the potential inhalation hazard by production technicians and utility operators when activities at a close distance to the emission source, are categorized as a dangerous or unacceptable risk. For the level of dermal risk of local effects (skin local), nine chemicals are in the high-risk category and two chemicals are in the medium risk category. While the level of risk of dermal systemic effects (skin uptake), four chemicals were in the moderate risk category, and seven chemicals were in the low-risk category. The results of the risk rating (RR) also determine the priority of action (Action Priority/AP) for controlling health risks. Control recommendations are to reduce the level of hazard (HR) by replacing chemicals (substitutions) with lower chemicals levels of danger to health, and for dermal exposure (ER), automation of handling processes, modification of work techniques by making chemical addition systems automatically. gravity, reducing the number of doses used but still being effective and efficient (workplace-related modifiers), reducing the time and frequency of using these chemicals (activity time), adding local ventilation (LEV) in addition to mechanical ventilation, and using special chemical resistant clothing and gloves or Chemical suit (control measures modifiers).

Menopause menyebabkan hipoestrogenisme dan mengakibatkan penuaan kulit. Fitoestrogen dari biji T. foenum-graecum (klabet) diharapkan dapat mengatasi penuaan kulit pascamenopause. Penelitian ini bertujuan untuk mengetahui konsentrasi optimal ekstrak klabet dalam menstimulasi sekresi COL1A1 dan COL3A1, cara kerjanya melalui jalur reseptor estrogen α (REα) atau REβ, dan peran klabet dalam mengurangi kerutan serta meningkatkan ketebalan kulit wajah.

Studi in vitro menggunakan human dermal fibroblast (HDF) tua yang diperoleh dari kultur sel fibroblas kulit perempuan pascamenopause dan HDF muda dari prepusium, dilakukan di Laboratorium Universitas YARSI. Sekresi COL1A1 dan COL3A1 diperiksa dengan ELISA lalu ditambah antagonis REa dan b. Penelitian in vivo merupakan uji klinis acak tersamar ganda berdurasi 12 minggu, di RSCM, Januari–November 2019. Subjek 50 perempuan pascamenopause yang dibagi dua: kelompok perlakuan mendapat krim klabet 5% dan kelompok plasebo mendapat krim dasar. Skor kerutan dahi, crow’s feet, dan nasolabial diukur dengan skoring atlas skin aging Bazin dan tebal dermis dengan high resolution ultrasound (HRU) 18 MHz.

Ekstrak klabet 2 µg/mL merupakan konsentrasi optimal dalam meningkatkan sekresi COL1A1 dan COL3A1 pada HDF tua dan muda dibandingkan tanpa perlakuan dan 5 nM estradiol. Uji inhibisi menunjukkan hambatan REα 50%; REβ dan RE α,β sampai 75%. Penurunan skor kerutan dahi, crow’s feet, dan nasolabial berbeda bermakna pada kedua kelompok minggu ke-4, ke-8, dan ke-12.  Peningkatan selisih skor kerutan dahi, crow’s feet, dan nasolabial tidak bermakna pada kedua kelompok antara baseline, minggu ke-4, ke-8, dan ke-12. Ketebalan dermis meningkat bermakna pada minggu ke-4 dibandingkan baseline. Pada minggu ke-8 dibandingkan minggu ke-4 dan pada minggu ke-12 dibandingkan minggu ke-8, ketebalan dermis menurun bermakna pada kedua kelompok. Peningkatan selisih ketebalan dermis pada minggu ke-4 dan ke-8 tidak bermakna.

Simpulan: Ekstrak klabet 2 µg/mL meningkatkan COL1A1 dan COL3A1 lebih banyak dibandingkan kelompok tanpa perlakuan dan estradiol 5 nM. Klabet bekerja terutama melalui REβ. Penurunan skor kerutan kulit dan peningkatan ketebalan kulit wajah tidak bermakna dibandingkan plasebo. Diduga, krim klabet konsentrasi 5% tidak tepat untuk mengurangi kerutan dan menambah ketebalan kulit. Perlu penelitian lebih lanjut untuk mengetahui konsentrasi optimal klabet sebagai terapi penuaan kulit wajah pascamenopause.

Hypoestrogenism in menopause leads to skin aging, for which phytoestrogen originated from the seeds of T. foenum-graecum (fenugreek) is expected to be a solution. This study aims to show the effect of phytoestrogen from fenugreek extract in stimulating COL1A1 and COL3A1 through its mechanism of action on estrogen receptor (ER) ERa or ERb and its role in diminishing facial wrinkles and increasing dermal thickness.

The in vitro study was carried out in YARSI University Laboratory throughout March 2017–March 2018. This study looks into the effect of fenugreek extract on collagen level secretion in old and young human dermal fibroblast (HDF) compared to control. The in vivo study was a randomized, double-blind, 12-week trial conducted in RSCM from January–November 2019. Fifty postmenopausal women divided into two groups: the intervention group was given 5% fenugreek cream while the placebo group was given base cream.

The in vitro study showed that a concentration of 2 mg/mL was the optimal dose to stimulate COL1A1 and COL3A1 secretion in both old and young HDF compared to control (no treatment) and 5 nM estradiol. The inhibition test demonstrated suppression of ERa by 50%; ERb and ERa,b by up to 75%, indicating that the fenugreek activates both receptors, especially ERb. However, the success of the in vitro study did not translate into the in vivo study. Both the intervention group and the placebo group were able to achieve statistically significant in facial wrinkle scores from all focus areas without any significant disparity between both groups at all timepoints. Dermal thickness of facial skin showed similar results for both groups with significant improvements in the 8^thweek compared to baseline and significant decrease by the 12^thweek.

Conclusion: Fenugreek extract with a concentration of 2 mg/mL increased COL1A1 and COL3A1 secretion more potently compared to control and estradiol 5 nM. However, the decrease in facial skin wrinkles scores and the increase in dermal thickness were not significant compared to placebo. We suspect that a concentration of 5% was not adequate for the expected antiaging effects. Further studies are necessary to determine a more appropriate fenugreek concentration to permit clinical use as a postmenopausal antiaging therapy.
