Abstract

Indonesia's increasing population is a crucial problem. According to the Central Bureau of Statistics (2021), Indonesia's population growth in 2020 will increase by 32.56 million people. In line with the need for housing in Indonesia, as a result the available land is decreasing, so many housing developments use partitions. However, partitions on the market still have many drawbacks. Utilization of pineapple leaf fiber as a substitute for fiber and blood clam shell waste as a substitute for cement is certainly a solution to this problem. Where pineapple leaf fiber has a carbon content such as 23.39% cellulose, 42.72% hemicellulose, and 4.03% lignin. Blood clam shells contain Sio2 of 8.252% and CaCO3 ranging from 66-98%. The purpose of this study was to determine the effect of the use of these two materials on the partition characteristics produced through physical tests and mechanical test. Samples were made in laboratory studies with variations of pineapple leaf fiber subs 0%;30%;70%;100% with the number of samples for each mold size being 3 samples. Through the results of tests that have been carried out, the best variation of pineapple leaf fiber substitution is the 70% variation. This test was also carried out by comparing several commercial partitions (gypsum, kalsiboard and GRC).

Abstract

In the implementation of construction projects, materials are a very influential component in determining the cost of a project. Residual material causes wastage and reduces project profits. Research is needed to analyze the implementation of Building Information Modeling (BIM) in efforts to minimize construction material waste. The population of the research is WIKA employees who have implemented BIM in the Jabodetabek area (Jakarta, Bogor, Depok, Tangerang and Bekasi). The research sample was 100 people. The data is processed using the Smart PLS software. The results showed that the implementation of BIM had a positive and significant effect on efforts to reduce residual construction materials. If the implementation of BIM is applied with discipline, stakeholders will have a more complete data source for estimating material needs.

Abstract

The distribution of Culex quinquefasciatus as a vector for several tropical diseases in Indonesia could affect the transmission of various pathogens, including filariasis, West Nile, encephalitis, and Rift Valley fever. The use of insecticides to control mosquito populations is carried out massively. However, this effort is threatened by an increase in mosquito resistance to insecticides, in this case, pyrethroids that target Voltage-gated sodium channel (VGSC) as a complex protein in mosquito nerve cells that plays a role in the movement of sodium ions, where these compounds can have a knockdown effect and lead to death. The existence of a single nucleotide mutation in this specific codon results in knockdown resistance (kdr) in mosquitoes. This study aims to determine whether there is a kdr mutation in the Vgsc-L1014F target using the latest molecular method ETAS-PCR to type tri-allelic variation at Vgsc-1014 in Cx. quinquefasciatus samples collected in three areas in the cities of Surabaya and Sidoarjo, namely Wonocolo, Sukodono, and Wonoayu. The result showed ten male pool samples (C1-C10) of Cx. quinquefasciatus did not carry mutations or present as homozygous wild type (TTT/TTT), with a DNA band size of 181 bp. Hence, this preliminary study could be extended for further research to build vector control monitoring programs.

Abstract

Problems related to the quality of red bricks are still frequently encountered, particularly cracks or damage that occur during the firing process. To minimize these problems, efforts are needed to improve the quality of bricks through material innovation. This study aims to analyze the optimal mixture composition by substituting corn cob ash and adding blood clam shell powder to produce red bricks. Corn cob ash is used as a substitute material to reduce water absorption, with variations of 3%, 4%, and 5%, while blood clam shell powder is added at 5% to enhance compressive strength. The research method used was experimental, where the sample production process was conducted directly at the production site. A total of 21 test specimens were prepared with dimensions of 220 mm × 95 mm × 45 mm. Testing was conducted in accordance with the SNI 15-2094-2000 standard, including testing of physical properties, size, water absorption, density, and compressive strength. The research results showed that the most optimal mixture was found in variation 7, consisting of 95% clay, 5% corn cob ash, and 5% blood clam shell powder. This composition produced bricks with water absorption of 18.06%, density of 1.3 g/cm³, and average compressive strength of 42.98 kg/cm². However, this innovation requires higher production costs compared to conventional red bricks.

Abstract

Highlights: • Vitamin D supplementations in different doses yield different outcomes. • Multi-day vitamin D administration of 1000-6000 IU in patients with COVID-19 has more positive impacts than a single high dose of vitamin D. • Patient morbidity, length of hospitalization, and patient mortality improved with multi-day vitamin D administration. Abstract: This meta-analysis aimed to determine whether there is any optimal dose of vitamin D for morbidity, length of hospitalization, and mortality in patients with COVID-19. We conducted a comprehensive search in three online databases for eligible studies until February 28, 2022. Odds ratio (OR) and standardized mean difference (SMD) were applied as summary statistics of primary outcomes. The study quality of the literatures collected was assesed using the Cochrane risk of bias tool version 2 (RoB 2). Eight randomized clinical trials (RCT) were included in the study. In our analysis, we found that there was no significant difference in morbidity when vitamin D was administered to COVID-19 patients [OR=0.50 (95% CI=0.13-1.96); SMD=-0.14 (95% CI=-0.55-0.28)]. Duration of hospitalization [SMD=-0.12 (95% CI=-0.39-0.15)] and mortality [OR 0.47 (95% CI=0.19-1.17)] of COVID-19 patients in five studies also showed no significant difference compared to patients who do not take vitamin D. However, when we analyzed two other studies, we found that in patients who did not take vitamin D, mortality was lower [SMD=0.43 (95% CI=0.29, 0.58)]. Compared to a single high dose of vitamin D, the multi-day vitamin D administration of 1000-6000 IU in patients with COVID-19 resulted in improved patient morbidity, length of hospitalization, and patient mortality.

Abstract

Dengue fever, caused by the dengue virus (DENV), poses a significant public health challenge, particularly in tropical regions. This study aimed to detect flavivirus presence, DENV serotypes, and knockdown-resistance (kdr) mutations in mosquito samples collected from Mengare Island, Gresik, Indonesia. A cross-sectional experimental design was employed, utilizing reverse transcription polymerase chain reaction (RT-PCR) for flavivirus detection and serotyping, as well as for identifying kdr mutations. Ribonucleic acid (RNA) extraction was performed using the Quick-RNA™ Miniprep Plus Kit (Zymo Research, Irvine, CA, USA), followed by RT-PCR with specific primers for DENV serotypes 1–4 and kdr mutations (V1016G and F1534C). Six adult female Aedes albopictus mosquitoes were analyzed in this study. The results revealed no evidence of flavivirus infection or DENV serotypes in the mosquito samples, as no complementary deoxyribonucleic acid (cDNA) bands corresponding to expected base pair sizes were observed on the agarose gels. Similarly, the analysis of kdr mutations showed that all samples were homozygous wildtype, with no mutations detected at the V1016G or F1534C loci. In conclusion, these findings suggest the absence of active dengue virus transmission or notable insecticide resistance in the studied mosquito population from Mengare Island. This study highlights the importance of continuous monitoring of flavivirus presence and resistance mutations. The variability in kdr mutation frequencies across regions underscores the need for sustained surveillance and effective control measures to mitigate potential outbreaks in high-risk areas such as Mengare Island.

Abstract

Highlights: 1. This study was the first in Gresik, Indonesia, to conduct mass screening of tuberculosis among waste workers, comprising various demographic profiles. 2. Although the tuberculosis screening of the waste workers showed negative results, mass examination using an acid-fast bacilli smear remains crucial to detect latent infections and prevent transmissions. Abstract Tuberculosis is a major source of illness and mortality worldwide. Therefore, tuberculosis screening is important to increase the number of active case-finding in a community. Bacteriological examinations can be used to initiate community-based active case-finding. Waste workers face a high risk of contracting Mycobacterium tuberculosis due to their constant exposure to waste. This study aimed to conduct bacteriological examinations to identify tuberculosis infections among waste workers in Gresik, Indonesia, who were considered a high-risk group. An analytical observational study was carried out throughout September 2023 in the Ngipik subdistrict, Gresik, East Java, Indonesia. The primary study was conducted using a cross-sectional design using interviews, measurements, and sputum examinations for all samples. The screening involved a total of 72 waste workers who had daily contact with various types of sewage and waste, including medical waste. The data were analyzed descriptively because of the constant variable. Following the analysis, the data were presented using a table and a figure. According to the acid-fast bacilli examinations, all of the samples yielded negative results. Nevertheless, this study concludes that it is imperative to carry out mass tuberculosis screening in various settings, specifically among those with a high risk. Mass screening can uncover the potential of latent tuberculosis and, thus, reduce its transmission.

Abstract

Highlights: • This research analyzed a previously understudied subject in Surabaya, Indonesia, and discovered knockdown resistance (kdr) mutations in Aedes albopictus. • The findings of this study can prompt further research, including bioassay testing and the development of more potent insecticides. Abstarct : Dengue hemorrhagic fever (DHF) has been endemic in Indonesia for decades. Insecticides are necessary to manage the transmission of the dengue virus. However, prolonged use of insecticides can lead to insecticide resistance. This study aimed to examine the genotype of mosquitoes using the allele-specific polymerase chain reaction (ASPCR) method. The ASPCR method was chosen for genotype detection due to its high sensitivity, affordability, and ease of design. Five mosquitoes were collected from human habitation in four different areas of Surabaya, Indonesia, namely Kranggan, Ulul Azmi Mosque, Ploso, and Kalijudan. Among them, three samples were identified as Aedes albopictus (A1, A2, and A5) and two samples were identified as Aedes aegypti (A3 and A4). The frequency of resistant alleles was analyzed using the Hardy-Weinberg package in RStudio version 2023.03.1. This study revealed that two mosquitoes carried homozygous mutant alleles with a band of 113 bp and three mosquitoes carried homozygous wild-type alleles with a band of 93 bp. Cysteine-to-cysteine (C/C) mutations and phenylalanine-to-phenylalanine (F/F) mutations at codon 1534 were observed in Aedes aegypti and Aedes albopictus mosquitoes. The homozygous mutant alleles were found in Kranggan, Surabaya, Indonesia. Further research is required to assess insecticide resistance and knockdown resistance (kdr)-like mutation by collecting more representative samples from larger areas within the region of Surabaya. Nevertheless, this study can be used as a reference for vector control and early prevention of dengue fever.

Abstract

Highlights: 1. Comics centered around tuberculosis offer a novel method tailored for specific audiences, specifically children or those of school age, to learn about the disease. 2. The tuberculosis comics feature the etiology, prevention, and treatment of tuberculosis conveyed through their unique design. 3. Comics can be an innovative promotional method to support the preventive campaign against tuberculosis. Abstract As a tropical country, Indonesia continues to grapple with the prevalence of tuberculosis. This study conducted by the Department of Public Health and Preventive Medicine at Universitas Airlangga, Surabaya, Indonesia, presented a novel approach to prevent tuberculosis through measures tailored to the socio-cultural context of the population. Specifically, this study assessed how effective the use of tuberculosis comics is as an educational tool to inform junior high school students about tuberculosis. This research was quasi-experimental, with a one-group pre-test-post-test design. Seventy junior high school students in Dukun District, Gresik, Indonesia participated in this study. Each participant received a questionnaire consisting of ten questions about tuberculosis. Afterward, tuberculosis education was shared through comics. The post-test was carried out using the same questions as the pre-test. The data were analyzed using the R Program for Windows, version 4.1.3 (Auckland University, New Zealand). The analysis revealed a significant difference between the pre-test and post-test results (p < 0.0001). As indicated by the data, comics proved to be an effective method of educating people about infectious diseases, specifically tuberculosis. Here, we introduce an educational tool designed to revitalize the educational method for disseminating knowledge about infectious diseases. Ultimately, comics can increase students' interest in learning about tuberculosis, including its etiology, prevention, and treatment strategies.
