Noise is unwanted sound and can cause health problems, one of which is work fatigue. This study aims to analyze the relationship between noise exposure and fatigue levels of workers at the stamping production station of PT X Plant Jakarta. The study used quantitative research methods with cross-sectional studies. The number of samples in this study are 125 workers. Data of noise is obtained from secondary data of companies that carry out routine measurements through monitoring measurement documents. Worker fatigue data was obtained using primary data through a questionnaire measuring feelings of work fatigue (KAUPK2) which had been tested for validity. Other variables as worker characteristics (age, length of work, shift work, and nutritional status) were also observed in this study. Based on statistical tests using the chi-square test, there was a significant relationship between noise exposure and work fatigue (p-value = 0.033, OR = 2.333). Also obtained significant results with work fatigue, namely age (p-value = 0.029, OR = 2.365) and work shift (p-value = 0.008, OR = 2.865). Based on result of the study, show that noise above NAB increases the workers risk of work fatigue, especially in old age workers and night shift workers

Stunting is a health problem which could affect the child's growth and development permanently. The cause of stunting is not only due to nutritional factors, but also several other factors such as maternal and child health history, environment and socio-economics. The purpose of this study was to determine the relationship of hygiene and sanitation with the incidence of stunting among under five age children in Sampang. This research was a cross sectional study with 207 samples in Sampang using a total sampling technique. Data was from the Riskesdas 2018 by the Indonesian Ministry of Health's Research and Development Agency.
The results showed that there is a significant relationship between hygiene and sanitation, namely the variable of waste management (OR 2,005; 95% CI: 1,037-3,879) and the use of latrines (OR 2,861; 95% CI: 0.973-8,417). A history of Upper Respiratory Track Infection was also significantly related to the incidence of stunting (OR 3.116; 95% CI: 1.071-9.062). Even if there’s no significant result for diarrhea, it showed that there was a risk by 1.9 times (OR 1.953; 95% CI 0.694-5.495). Based on the results of the study, it’s recommended to society improving their knowledge and quality of protection of Clean and Healthy Living, health for mothers and children, as well as improving the guidance and improvement of health-sanitation infrastructure by the Sampang District Health Office.
Environmental problems that can not be avoided in various countries is air pollution. There are many causes of air pollution, one of which is caused by dust particles, especially in PM2,5. PM2,5 is defined as ambient air particles that are up to 2.5 microns in size. Air pollution occurs not only in the ambient air, but also in the indoor air. This study aim to determine the relationship of indoor PM2,5 concentration exposure against lung function impairment of adults living around Industrial Area Tegalratu Village, Ciwandan District, Cilegon. This research uses a cross-sectional study design. Data collection was conducted on April to May 2022. The participants were identified using random sampling method based on inclusion and exclusion criteria that have been set. The number of samples in this study were 200 adults. The analytical results obtained of 124 adults (87.3%) had PM2,5 concentrations in their homes were not qualified to suffer from lung function impairment, while there were 34 adults (58.6%) whose PM2,5 concentrations in their homes were qualified to suffer from lung function impairment. The results of this study found a significant associated between exposure to PM2,5 concentrations of lung function impairment in adults living in industrial areas. Confounding variables that affect exposure to PM2,5 concentrations include the use of mosquito coils, nutritional status, age, disease history, cooking fuels, type of house floor and smoking status. The conclusion of this study found a significant relationship between PM2,5 concentration, age, nutritional status, and type of house floor with the incidence of lung function impairment.
Pencemaran mikroplastik semakin meningkat setiap tahunnya dan berpotensi menimbulkan risiko kesehatan bagi masyarakat. Kebijakan pemerintah terkait pengelolaan mikroplastik menggunakan model ekonomi sirkular dan model 3R (reduce, reuse, recycle) terus dilaksanakan, namun belum menyelesaikan tantangan di lapangan. Sehingga diperlukan alternatif pengelolaan mikroplastik melalui teknologi degradasi menggunakan mikroorganisme. Penelitian ini bertujuan untuk mengembangkan model bioteknologi degradasi mikroplastik berbasis bakteri indigenous berasal dari Tempat Pembuangan Akhir (TPA) Cipayung Kota Depok.
Penelitian ini merupakan penelitian kuantitatif dengan pendekatan observasional, penilaian risiko kesehatan dan eksperimental. Studi observasional dilakukan untuk mengidentifikasi mikroplastik pada sampel tanah dan air bersih serta mengetahui jenis dan kemampuan isolat bakteri dalam mendegradasi mikroplastik. Pendekatan eksperimental untuk mengembangkan model bioteknologi degradasi mikroplastik berbasis bakteri indigenous.
Hasil penelitian menunjukkan bahwa konsentrasi mikroplastik di tanah TPA Cipayung bervariasi antara 8.400–152.000 partikel/kg, sementara pada air bersih yang dikonsumsi masyarakat berkisar antara 1.889–5.444 partikel/L, dengan variabilitas tingkat risiko kesehatan terkategori Risk Quotient (RQ) > 1. Empat isolat bakteri potensial, yaitu Rummeliibacillus pycnus NBRC 101231, Stenotrophomonas acidaminiphila JCM 13310, Microbacterium arborescens DSM 20754, dan Streptomyces thermolineatus DSM 41451, efektif mendegradasi mikroplastik melalui penurunan berat, perubahan struktur kimia (Fourier Transform Infrared Spectroscopy), serta pembentukan biofilm, lubang dan retakan (Scanning Electron Microscope). Model bioteknologi degradasi mikroplastik dikembangkan dalam bentuk produk liofilisasi biomassa bakteri, menggunakan isolat Rummeliibacillus pycnus NBRC 101231.
Saran yang diajukan adalah perlunya penetapan regulasi batas aman mikroplastik di lingkungan serta mendukung pengembangan bioteknologi degradasi mikroplastik berbasis biomassa bakteri sebagai solusi pengelolaan yang berkelanjutan. Untuk penelitian selanjutnya, diperlukan uji implementasi dan akseptabilitas model bioteknologi ini untuk memastikan efektivitas dan penerimaan di tingkat masyarakat.
Microplastic pollution continues to increase annually, creating potential threats to public health. Government policies related to microplastic management, which rely on circular economy models anda 3R model (reduce, reuse, recycle), are being implemented, but have yet to address the challenges in the field. Therefore, alternative microplastic management strategies that utilize degradation technologies with microorganisms are required. This study aimed to develop a biotechnology model for microplastic degradation based on indigenous bacteria sourced from the Cipacung Landfill, Depok City. This study employed a quantitative approach that combined observational, health risk assessment and experimental methods. Observational study was conducted to identify microplastics in soil and clean water samples, and to determine the types and capabilities of bacterial isolates in degrading microplastics. The experimental approach was applied to develop a biotechnological model for microplastic degradation based on indigenous bacteria.
The study results show that the concentration of microplastics in the soil at the Cipayung Landfill varies between 8.400-152.000 particles/kg, while in clean water consumed by the community, it ranges between 1.889-5.444 particle/L with variability in health risk levels categorized as Risk Quotient (RQ) >1. Four potential bacterial isolates, Rummeliibacillus pycnus NBRC 101231, Stenotrophomonas acidaminiphila JCM 13310, Microbacterium arborescens DSM 20754, and Streptomyces thermolineatus DSM 41451, were effective in degrading microplastics. This was demonstrated through weight reduction, changes in the chemical structure (Fourier Transform Infrared Spectroscopy), and the formation of biofilms, holes, and cracks (Scanning Electron Microscope). Biotechnology model for microplastic degradation was developed in the form of a lyophilized bacterial biomass product, utilizing the isolate Rummeliibacillus pycnus NBRC 101231.
The proposed recommendations include establishing safe limits for microplastics in the environmnent and supporting the development of biotechnology for microplastic degradation based on bacterial biomass as a sustainable management solution. For future research, implementation trials and acceptability assessments of this biotechnology model are needed to ensure its effectiveness and community acceptance.
