Abstract

Air pollution can lead to exposure to substances from exhaust gases. Carbon monoxide (CO) and lead (Pb) are harmful substances that can negatively impact the health of outdoor workers. Workers such as street sweepers and waste collectors are particularly susceptible to these exposures due to their daily street activities. Therefore, health assessments, such as hemoglobin (Hb) examinations, are essential. This study involved a literature review, distribution of questionnaires, interviews with the research population, laboratory tests, and analysis of the results. The study included 67 respondents, the majority of whom were male (97%) and in the productive age group of 21–40 years (62.7%). Most respondents worked more than 8 hours daily (91%), increasing their risk of exposure to hazardous substances. The results showed that 65.7% of respondents had normal hemoglobin levels, 32.8% had elevated levels, and 1.5% had low levels. Workers' knowledge about the dangers of Pb and CO (70.1%) showed no significant correlation with hemoglobin levels. However, knowledge remains crucial for encouraging protective behaviors such as the use of personal protective equipment. This study highlights the importance of education and safety training to protect the health of outdoor workers.

Abstract

Tandan Kosong Kelapa Sawit (TKKS) merupakan limbah kelapa sawit yang dapat dikonversi menjadi material karbon bernilai tambah. Hasil konversi karbon disintesis dengan Fe3O4 menjadi nanokomposit yang memiliki potensi sebagai anoda baterai lithium. Penelitian ini bertujuan menentukan metode aktivasi karbon dari TKKS agar memiliki porositas optimal. Karbon yang terbentuk disintesis menjadi nanokomposit dan dikarakterisasi menggunakan XRD, FTIR, serta Adsorpsi-Desorpsi N2 (BET). Hasil sintesis nanokomposit dikarakterisasi dengan XRD dan BET. Hasil karakterisasi menunjukkan karbon dengan porositas terbesar diperoleh melalui aktivasi perendaman KOH (TKP) dengan luas permukaan 852 m²/g dan volume pori 0,64 m³/g. Nanokomposit disintesis dengan rentang variasi massa karbon (NFC-X) 0,25–1,5 g. Karakterisasi menunjukkan porositas terbesar pada NFC-1,25 dengan luas permukaan 1080 m²/g dan volume pori 0,89 m³/g tanpa merusak struktur nano Fe₃O₄, yang dibuktikan dengan tidak berubahnya puncak khas material Fe₃O₄.

Abstract

Dengue Hemorrhagic Fever (DHF) is an infectious disease caused by the dengue virus (DENV), which is transmitted through the bite of Aedes aegypti mosquitoes. These mosquitoes act as the primary vectors carrying the dengue virus. The spread of DHF primarily occurs in tropical and subtropical regions. Mosquito control can be carried out using various methods, one of which is chemical control. However, the long-term use of chemical insecticides may lead to mosquito resistance, highlighting the need for safer alternatives to synthetic insecticides. One such alternative is the use of plant-based extracts. The butterfly pea plant (Clitoria ternatea) has shown potential as a natural larvicide due to its content of flavonoids, tannins, and anthocyanins, which function as antioxidants and are toxic to mosquito larvae. This study aims to determine the potential of Clitoria ternatea flower extract as a natural larvicide against Aedes aegypti larvae. The results of the effectiveness test showed that Clitoria ternatea flower extract has significant larvicidal potential against Aedes aegypti larvae. Observed larval mortality at 24 hours was 22 larvae at 10% concentration, 23 larvae at 50%, and 25 larvae (100%) at 100% concentration. The LC₅₀ value obtained from the test was 36.78%, indicating the extract's potency as a natural larvicide.

Abstract

This study explores the relationship between smoking habits, hemoglobin levels, and awareness of carbon monoxide (CO) risks among street cleaning workers. Smoking is one of the most common sources of CO exposure, which can bind to hemoglobin and reduce oxygen transport in the body. A total of 67 street cleaning workers in West Jakarta were involved in this research, using a descriptive analytic approach. Data were collected through blood tests for hemoglobin levels, as well as interviews and questionnaires to assess smoking habits and knowledge of CO. The findings show that most respondents were light smokers (1–10 cigarettes per day), and 43% had been smoking for less than five years. While 66% of participants had normal hemoglobin levels, 33% had elevated levels, which may reflect the body’s response to reduced oxygen availability. Interestingly, 70% of respondents were aware of the health risks of CO, but knowledge tended to decline among long-term or heavy smokers. This indicates a gap between behavior and risk awareness. The study highlights the need for ongoing health education targeted at outdoor workers to increase understanding of CO exposure and prevent potential health impacts.
