Lead is one of the toxic chemicals causing dangerous air pollution in the environment and its very dangerous for human health whose toxicity lasts for a lifetime because lead accumulates in the human body. Lead is one of the components of the battery that is needed as the basic material for making batteries. Used batteries can be recycled by melting the lead contained in the plates into black bars that can be reused as raw material for making new batteries. This research was aimed to assess the magnitude of emerging health risk of ambient air Pb exposure to residence at smelter batteries area. This study uses a design of public health risk analysis or also called Public Health Assessment. The subject of this study is the human population at risk of being exposed to Pb in this case the people living around the former battery smelter in Cinangka Village. The highest concentration of Pb measured in the former battery smelting area was 0,91 μg/Nm3 and the lowest concentration was 0,04 μg/Nm3. The biggest intake realtime received by individual was 12,64 × 10-5 mg/Kg/day. The results of the calculation of individual RQ were found that 10,9% (11 respondents) who had a non-carcinogen risk and needed risk management actions. Most of the respondents were experienced one of the symptoms of respiratory problems as much as 86,1%. Further research on particle toxicology evaluation is recommended.

Kusta masih menjadi masalah kesehatan masyarakat di Indonesia, termasuk di Kabupaten Bekasi. Desa Mekarwangi merupakan salah satu wilayah dengan kasus kusta yang cukup tinggi dan telah ditetapkan sebagai Desa Siaga Bebas Kusta pertama di Kabupaten Bekasi. Penelitian ini bertujuan untuk menganalisis faktor risiko yang berhubungan dengan kejadian kusta di wilayah kerja Puskesmas Desa Mekarwangi, Kabupaten Bekasi, tahun 2026. Penelitian ini menggunakan desain observasional analitik dengan pendekatan case control. Sampel penelitian terdiri atas 75 responden, yaitu 25 kasus kusta dan 50 kontrol dengan perbandingan 1:2. Data diperoleh melalui wawancara menggunakan kuesioner serta observasi kondisi lingkungan rumah. Analisis data dilakukan secara univariat, bivariat dengan uji chi square, dan multivariat menggunakan regresi logistik biner. Analisis multivariat menunjukkan bahwa faktor dominan yang berhubungan dengan kejadian kusta adalah riwayat kontak erat (OR=66,77; 95% CI=10.46—426.14). Hasil ini menunjukkan bahwa responden yang memiliki riwayat kontak erat dengan penderita kusta memiliki peluang 66,77 kali lebih besar mengalami kusta dibandingkan responden yang tidak memiliki riwayat kontak erat dengan penderita kusta lainnya. Penelitian ini menyimpulkan bahwa riwayat kontak erat menjadi faktor utama yang berhubungan dengan kejadian kusta di wilayah kerja Puskesmas Desa Mekarwangi. Penguatan pelacakan kontak, active case finding, dan edukasi masyarakat perlu diprioritaskan dalam program pencegahan dan pengendalian kusta.
Leprosy remains a public health problem in Indonesia, including in Bekasi Regency. Mekarwangi Village is one of the areas with a relatively high number of leprosy cases and has been designated as the first Leprosy-Free Alert Village in Bekasi Regency. This study aimed to analyze the risk factors associated with leprosy incidence in the working area of Mekarwangi Public Health Center, Bekasi Regency, in 2026. This study used an analytical observational design with a case-control approach. The study sample consisted of 75 respondents, including 25 leprosy cases and 50 controls with a 1:2 ratio. Data were collected through interviews using questionnaires and observations of household environmental conditions. Data analysis was conducted using univariate analysis, bivariate analysis with the chi-square test, and multivariate analysis with binary logistic regression. The multivariate analysis showed that the dominant factor associated with leprosy incidence was close contact history (OR=66.77; 95% CI=10.46–426.14). This finding indicates that respondents with a history of close contact with leprosy patients had 66.77 times higher odds of developing leprosy than respondents without a history of close contact with leprosy patients. This study concludes that close contact history is the main factor associated with leprosy incidence in the working area of Mekarwangi Public Health Center. Strengthening contact tracing, active case finding, and community education should be prioritized in leprosy prevention and control programs.
Diarrhea is an communicable disease and ranks the second cause of death for children under-five in the world. In Indonesia, especially West Java, which is an endemic area for diarrhea, Bogor is one of the districts with a fairly high prevalence of diarrhea in children under-five. Purwasari Community Health Center is a health center with the highest cases of diarrhea in children under-five in Bogor Regency. This study aims to analyze the risk factors (characteristics of children under-five, characteristics of mothers, and sanitation facilities) for the incidence of diarrhea in children under-five in the Purwasari Public Health Center, Bogor Regency in 2022. This study used a case-control research design with a sample of 53 cases and 53 controls. Data analysis was performed using chi-square test and logistic regression predictive model. The results showed that there was a relationship between exclusive breastfeeding (0,28; 0,11-0,67), measles immunization (0,18; 0,08-0,42), knowledge (0,16; 0,07-0,38), toddler stool disposal behavior (0,18; 0,07-0,46), and latrine facilities (0,32; 0,14-0,72) with the incidence of diarrhea in children under-five. The variable that is predicted to have the most influence on the occurrence of diarrhea under five in the working area of the Purwasari Health Center is the knowledge variable (9,76; 2,78 - 34,21).
