Abstract

Environmental pollution caused by heavy metals can be found in various media, both soil, water and air, and these components occur in very small particles. The selected study locations are located near areas with intensive industrial activities, in the coastal areas of southern China and other industrial areas in Sidoarjo Regency, East Java, Indonesia. In both locations there are similarities, in terms of the characteristics of the soil industry with the parameters of heavy metals Pb, Cd, Zn, Cu. The difference lies in the depth of the soil sample taken. In China, soil samples were taken at the soil surface (0-20) cm and below the soil surface (20-40) cm, while in Sidarjo Regency only at the soil surface (0-20). ) cm. The number of samples taken in South China is greater than in Sidoarjo. Comparing the results of the South China and Sidoarjo industrial areas, it was found that there were differences in the heavy metal content in polluted soil, that heavy metals are produced from natural and anthropogenic sources such as natural weathering, fertilizer application, and transportation. The origin of Hg, Cd, Ni, and Pb probably comes from human activities such as excessive use of pesticides and fertilizers, while Pb probably comes from vehicle exhaust. The heavy metal content of Cadmium (Cd) is dominant in the soil of South China, while in Sidoarjo, East Java, Indonesia, the content of heavy metals is mainly Lead (Pb) and Mercury (Hg).

Abstract

Aedes aegypti mosquitoes are known vectors for Dengue Fever (DF). This disease is caused by the Dengue virus, necessitating control measures that do not harm public health. One such measure is the use of ginger powder (Zingiber officinale) as a larvicide against Aedes aegypti larvae, the vector of DF. This experimental study employed a Completely Randomized Design with statistical analysis using the F-test. Four treatment concentrations and one control were tested: 5 grams, 10 grams, 15 grams, and 20 grams, with three repetitions for each treatment, observed over a 4-hour period. The study aimed to determine the effect of ginger powder (Zingiber officinale) as a larvicide on Aedes aegypti larvae. The average larval mortality at a concentration of 5 grams was 4.3 larvae, 7.6 larvae at 10 grams, and 10 larvae at both 15 grams and 20 grams. The F-test results showed that at the 1% level, Fht > Ftb. Duncan's Multiple Range Test indicated that the effective concentration was 15 grams, at which all Aedes aegypti larvae died within 4 hours. The utilization of ginger powder (Zingiber officinale) as a larvicide, with varying amounts of powder, resulted in different larval mortality rates. The higher the concentration of ginger powder (Zingiber officinale), the higher the larval mortality rate of Aedes aegypti.

Abstract

As a tropical country, Indonesia has various plants that can be utilized for human needs. One such plant is Bintaro (Cerbera manghas). Bintaro contains secondary metabolites that can be used as a bioinsecticide. These secondary metabolite compounds can degrade if dried at high temperatures. This study focused on optimizing the drying temperature of Bintaro fruit seeds (Cerbera manghas) using a tray dryer to produce bioinsecticide. The research employed a Completely Randomized Design (CRD) with four different drying temperature treatments: 40°C, 50°C, 60°C, and 70°C. The ethanol extracts from Bintaro seeds produced at each temperature treatment were tested for their effectiveness as a bio-insecticide against Aedes aegypti mosquitoes. The results indicated that the optimal drying temperature for Bintaro seeds, which provided the best bioinsecticide effectiveness, was 50°C.

Abstract

Background: Filariasis patients can be a source of transmission if their blood still contains microfilariae. One of the Polymerase Chain Reaction (PCR) methods used is High Resolution Melting (HRM), using primary specificity testing. Purpose: To test the specificity of SLX primer. The samples used for this test were isolates of Salmonella., Klebsiella, Pseudomonas, negative and positive controls for Brugia malayi and Wuchereria bancrofti. Method: The design in this study is a quasi-experiment by testing the specificity of SLX primer using HRMbased real-time PCR based on the Cycle Threshold (CT) value observed through the amplification curve. Result: The real-time PCR results showed that no CT was released in the bacterial samples, and there was a CT value in the positive control. The results of this study indicate that specific SLX primer can be used in identifying microfilariae. Conclusion: SLX primer have a reasonable specificity because they cannot detect the existence of microorganisms in the samples other than microfilariae.

Abstract

Background: The presence of filarial worms in the lymph nodes can result in acute symptoms, such as inflammation of the lymph nodes and ducts, particularly in the groin region. As part of the life cycle of filariasis, symptomatic or asymptomatic patients with microfilariae in their blood can transmit the disease via mosquito bites. The inspection of microfilariae that is currently being developed uses Polymerase Chain Reaction (PCR) to carry out a unique DNA search technique. Purpose: Identify the type of microfilaria present in filariasis patients using Quantitative PCR High- Resolution Melting (qPCR-HRM) and conventional PCR techniques. Method: This study involved the examination of 19 samples using the qPCR-HRM method. Subsequently, the results that were considered positive for microfilaria underwent further testing using conventional PCR. Result: The results of the examination using these two methods revealed the presence of Brugia malayi and Wuchereria bancrofti microfilariae with peak melting temperatures ranging from 78.2 – 78.7 °C and 80.8 – 81.2 °C, and fragment sizes of 199 bp and 227 bp, respectively. Conclusion: Based on the results of the identification from these two methods, it is evident that microfilariae of Brugia malayi and Wuchereria bancrofti can be detected using both conventional and qPCR-HRM methods.

Abstract

Environmental factors are the biggest determinant of the incidence of Upper Respiratory Tract Infection (URI). Physical parameters of a house that do not meet the requirements increase the risk of Upper Respiratory Tract Infection, especially in children under five. This study aims to analyze the physical parameters of air quality (temperature, lighting, humidity, and ventilation) in the house with the incidence of Upper Respiratory Tract Infection in infants in the Regional Technical Implementation Unit of North Pontianak Public Health Center in 2018. The method used is analytic observation using the Cross-Sectional approach. The population in this study was 2884 children under five with a sample of 93 children under five. The analysis was performed with the Chi-Square test with a 95% confidence level. The results showed that there was a significant relationship between temperature and the incidence of URIs (p-value = 0.002 OR values ​​= 6.648), humidity with URI events (p-value 0.035 OR values ​​= 3.625), lighting with URI events (p-value = 0,000 OR value = 15.037), and there is no significant relationship between ventilation and the incidence of URI (p-value 0.383 OR value = 2.112).
