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

Coronary heart disease (CHD) continues to be a leading cause of hospital readmissions, especially among elderly individuals with low educational attainment and limited understanding of health information. This research aimed to evaluate how cardiac care management influences the frequency of hospital readmission in patients diagnosed with CHD. Employing a quasi-experimental method with a one-group pretest-posttest design, the study involved 100 participants at Jombang Hospital, chosen through purposive sampling. Information regarding readmission rates was gathered before and after the intervention using structured questionnaires and assessed through the Wilcoxon signed-rank test. Before receiving the intervention, 25% of patients had been readmitted more than twice, while none avoided readmission altogether. Following the management program, only 5% experienced multiple readmissions, and 25% reported none. The statistical outcome demonstrated a significant difference (p = 0.002), proving that cardiac care interventions consisting of educational support, family involvement, and consistent follow-up effectively decreased patient readmission. Most participants were aged between 61 and 75, male, and had only completed elementary school, all of which are factors associated with poor disease self-management. This trial confirms that integrated cardiac care management greatly improves the outcomes of recovery and decreases the risk of rehospitalization in CHD patients.

Abstract

Background: Hypertension is amongst the top 10 non-communicable diseases and is the leading cause of premature death worldwide. Multiple factors contribute to the occurrence of hypertension. Risk factors include modifiable ones, such as lifestyle, smoking habits, sleeping patterns, caffeine consumption, physical activity, high-sodium diet, and stress levels. On the other hand, factors such as gender and age are non-modifiable. A primary survey in Kalirejo, Lawang, showed that hypertension is the leading health issue. This research aims to analyze the association between body mass index, physical activity level, and stress level with hypertension in Kalirejo, Lawang.Method: This research is a correlative analytical descriptive study using the cross-sectional method that involves 99 residents aged ≥ 45 years old in Kalirejo. Results: This study revealed that the largest age group in Kalirejo is elderly people, with most respondents being female, non-smokers, and with no family history of hypertension. A majority of the respondents consume caffeine and use minimal salt. The largest BMI distribution is within the normal category (41.4%). High physical activity is found to be more frequent (45.5%), and stress level is primarily low (62.6%). Bivariate analysis shows a significant association between BMI and hypertension (p<0.05). Meanwhile, physical activity and stress levels are irrelevant to the occurrence of hypertension. This study discovered that there is a significant association between BMI and hypertension, and a non-significant association between physical activity and stress level with hypertension, respectively, among pre-elderly and elderly residents in Kalirejo.
