The Effect of Rekattidiri Ovitrap Towards Aedes Aegypti Larval Density

Dengue Hemorrhagic Fever (DHF) is a health problem in Indonesia. The entire region of Indonesia at risk of contracting dengue disease. The study aims to prove the effect of modifications ovitrap rekattidiri on the density of larvae (HI: House Index, CI: Container Index and BI: Breteu Index) as well as comparing the differences between the mean larvae trapped between ovitrap Rekattidiri with standard ovitrap. Using a quasi experimental design, time series experimental design with Control group. Population subjects were Aedes aegypti at the endemic sites in Pontianak, West Borneo. The results showed larval density index in the intervention area decreased each ie HI from 26% to 3%, CI of 6.95% to 2.19 %, and BI from 29% to 13%. The number of larvae trapped in ovitrap rekattidiri ie 70% (12,770 larvae) more than the standard ovitrap in the control and intervention, namely: 17% (3,057 larvae) and 13% (2,334 larvae). It is concluded that there are significant modifications Rekattidiri ovitrap against larval density index (HI p-value: 0.025, CI p-value: 0.052, BI value of p: 0.04) and there are differences between the mean larvae trapped in ovitrap Rekattidiri and standard ovitrap with p value: 0.001

Perbedaan Kapasitas Vital Paksa Paru Tenaga Kerja pada Lokasi Pengecoran/ Pencetakan dan Lokasi Pengikiran/Pembubutan di Industri Kerajinan Cor Aluminium “ED” Giwangan YOGYAKARTA.

Background: Dust pollution can be exist at production process on industry, include on “ED” aluminium cast indust, Yogyakarta which is on the production process included foundry and fitting-shop process. Aluminium dust can influence lung function of the worker. The aim of this research was to study the difference of forced vital capacity (FVC) on workers between foundry and fitting-shop in “ED” aluminium cast industry, Giwangan Yogyakarta. Method: This was an observational research using cross sectional design. The population was 15 workers on each location. The data was collected using questionnaire, measuring of lung function and total dust content. The data would be analyzed using Mann-Whitney test. Result: The result showed that the average of total dust content on those location was 0.65 mg/m3 and 2.75 mg/m3 orderly. This was still below the threshold value (10 mg/m3). The measuring of lung function showed that 73.35% of workers in foundry and 66.6% of workers in fitting-shop had FVC decreasing with the average of FVC was 75.80% and 77.27% in order. The statistic test showed that there was no significant difference of FVC between those workers. Conclusion: No significant difference of FVC on workers between foundry and fitting-shop in “ED” aluminium cast industry, Giwangan Yogyakarta

Hubungan Pajanan Benzene dengan Temuan Retikulosit, Kadar Hemoglobin Darah, dan Kadar Fenol dalam Urine Pekerja Industri Sepatu X Jakarta

Benzene exposure through the use of glue could cause serious risks for the human body. One of the target organ of benzene exposure was the bone marrow. Chronic effects of benzene exposure was damage to the blood formed system, such as damaged to the bone marrow, caused a decrease in blood cell counts. Phenol urine could be used as an indicator of exposure to benzene. The purpose of this study was to determine the correlation between benzene exposure by reticulocytes, hemoglobin, and urine phenol shoe industry. This study used a quantitative method with cross sectional approach. Population and sample of 30 people who were determined by the total sampling method. The results of the study by Chi Square test showed that there was no correlation between the concentrations of benzene-reticulocytes (p-value = 1.000), work period-reticulocytes (p-value = 1.000), retikulosit- hemoglobin (p-value = 1.000), the concentration of benzene -hemoglobin (p-value = 0.304), work period-hemoglobin (p-value = 1.000), urine concentrations of benzene-phenol (p-value = 1.000), and work period-phenol urine (p-value = 1.000). Factors that determined the results of the study include the relatively concentrations of benzene, continuity of exposure, phenol urine test was not specific and sensitive. Researchers suggest that the industry owners should always use PPE at work, and conducted periodic health examinations. For further research to measured the concentration of benzene with personal sampling, use a urine test was more specific and sensitive, and use the study cohort in the study area

Faktor-Faktor yang Berhubungan dengan Kejadian Dermatitis Kontak Iritan pada Pekerja Bagian Premix di PT. X Cirebon

Irritant contact dermatitis is a local non-immunologic inflammatory reaction of the skin caused by contact with exogenous or endogenous factors. This disease is characterized by inflammation of the polymorphic skin traits that have broad identification, such as: itching, redness, scaling, vesicles, and crusting papulovesikel. PT X is an industry which is engaged in the production of animal feed in Cirebon City. The production process is divided into several stages, weighing ingredients according to recipe, coarse crushing raw materials, mixing all the ingredients according to recipe, pellet forming and crumble establishment. Before mixing the main ingredient there was a process of weighing chemicals and feed supplement as prescribed in premix company section. The purpose of this research was to analyze the factors associated with the occurrence of irritant dermatitis contact in Premix workers in PT X Cirebon. The type of the research is an observational study with cross sectional approach. The subjects were 40 workers as part of Premix respondents. The results of the chi square test statistic obtained contact with the chemical (p value = 0.0001), years (p value = 1.000), duration of exposure (p value = 0.003), age (p value = 0.003), gender (p value = 0.017), knowledge (p value = 1.000), use of personal protective equipment (p value = 0.369), personal hygiene (p value = 0.689). The conclusion of this study is in contact with chemicals, long exposure, age and gender, associated with the incidence of irritant dermatitis contact. While working life, knowledge, use of personal protective equipment, and personal hygiene are not associated with the incidence of irritant contact dermatiti

Faktor Risiko Peningkatan Ambang Dengar Pekerja Pengelasan (Studi Observasional Pada PT. X Kota Semarang Berdasarkan Umur Dan Riwayat Penyakit)

PT. X is one of the companies engaged in the construction and renovation of buildings that have high noise. Welding workers at PT. X has the risk of exposure to noise from machines cutting and welding metal. The research objective was to analyze the risk factors for the increase in the hearing threshold welding workers at PT. X Semarang based on the age and history of the disease. This study was an observational study with cross sectional analytic. Welding in the working population PT. X as many as 50 people with a sample of 33 people obtained using purposive sampling with inclusion criteria, age 35-70 years old, had no history of hearing, and willing to become respondents. The independent variable in this study is the hearing threshold, while the dependent variable is the age, working life, history of hypertension, history of diabetes mellitus. Methods of data collection using equipment Sound Level Meter to measure noise, Audiometer to measure the hearing threshold, Sphygmanometer to measure blood pressure, Nesco Multicheck to measure blood glucose, and questionnaires. Results of univariate analysis obtained the highest worker age ≤ 40 years (60.6%), working life > 10 years (87.9%), history of hypertension (24.2%), history of diabetes mellitus (21.2%). Bivariate analysis results obtained age (p = 0.435, OR = 0.571), age (p = 0.607, OR = 0.357), and diabetes mellitus (p = 0.203, OR = 4.000) is not a risk factor for the increase in the hearing threshold. While a history of hypertension (p = 0.012, OR = 14.875) is a risk factor for the increase in the hearing threshold. Workers need to maintain health and healthy lifestyle for patients with hypertension that do not have a hearing loss is more severe. In addition, the company is also required to provide a form of earmuff PPE for workers due to occupational noise range 110d
