RISK MANAGEMENT IN MORTAR: ENGINEERING, ECONOMIC, AND ENVIRONMENTAL USE OF STONE POWDER WASTE Setya Winarno International Journal of Geomate, 2025 Investing in construction material risk management, enhanced by advanced technologies and sustainable methodologies, is vital for ensuring material quality, improving efficiency, and maintaining cost competitiveness in construction projects.One of the wastes that requires a sustainable solution is stone fine powder (SFP), a solid by-product of the stone-cutting industry.This research examines the risk management issues associated with construction materials by effectively applying SFP in producing new dry mortar as an alternative to ordinary cement mortar, focusing on their engineering properties, economic aspects, and environmental benefits.The SFP-based mortar was a mixture of ordinary cement, SFP, and water.Research samples were categorized into five cement-SFP ratios, each including five samples.The commercially available dry mortars were tested using the same methodology as the newly investigated mortar.Interviews with industry owners and local community leaders were undertaken to emphasize the manufacture of mortar as a solution to environmental waste challenges.Three primary variables pertain to the risk management of SFP-based mortar manufacturing: optimal proportion of SFP, affordable price of the new mortar, and environmental considerations.The optimum ratio for the newly developed SFP-based mortar is one part cement to two parts SFP, since it satisfies the minimal requirements for shear strength.The economic evaluation has revealed that the price of the new mortar is 15.48% lower than the typical commercial market pricing.Additionally, the new developed mortar is more ecologically sustainable, since it incorporates waste materials, reducing carbon footprint emissions.
Differences in Before and After Temephos Intervention in Bengkulu City: Larvae Free Rate of Aedes spp. Lala Foresta Valentine Gunasari, Rizqita Destilyana, Nikki Aldi Massardi, Dessy Triana Jurnal Presipitasi, 2025 One of the strategies to reduce dengue transmission is to control the population of vectors, such as larval eradication. The use of temephos larvicide (Abate®) is the most widely carried out in the community. An indicator of the success of the larval eradication program is the Larvae Free Rate (LFR) assessment. This study aimed to determine the difference between LFR of Aedes spp. before and after temephos intervention in Bengkulu City. This study is experimental research with one group pre-test and post-test design. The population of this study was all houses in Bengkulu City with a total sample of 670 houses. Sampling was carried out using cluster random sampling techniques in 67 urban villages in Bengkulu City. This research was carried out by conducting a survey of larvae before and after temephos intervention in containers. Sixty-seven urban-villages, in 44 (65,67%) urban-villages was found an increase of LFR after temephos intervention. The average LFR before temephos intervention was 67.61%, while after temephos intervention increased to 82.98%, there was a significant difference between LFR of Aedes spp. before and after temephos intervention in Bengkulu City (p=0.001). Temephos intervention is effective to increase LFR of Aedes spp. in Bengkulu City.
Mapping of the Oviposition Ability, Survival Rate, and Distribution of Dengue Vector in Bengkulu City, Indonesia Lala Foresta Valentine Gunasari, Tsaniyah Pasandra, Nikki Aldi Massardi, Dessy Triana Bio Web of Conferences, 2024 Vector surveillance is pivotal for dengue prevalence. The oviposition ability, survival rate, and distribution of dengue vector species can indicate the population density and are components of mosquito survival strategies. The density of dengue vectors is influenced by altitude, population density, water sources, and vegetation characteristics in their breeding habitats. This study aims to determine the oviposition ability, survival rate, and distribution of dengue vectors in Bengkulu City. This study employed a quantitative method with a descriptive observational design. Data were obtained by collecting Aedes spp. eggs from 67 urban villages in Bengkulu City. The survival rate was determined through colonization, and the distribution of mosquito species was analyzed based on the mosquitoes resulting from colonization. Beringin Raya was identified as the urban village with the highest oviposition ability, while Kandang was identified as the lowest. The highest survival rate of dengue vectors was found in Jalan Gedang, while the lowest was found in Sumber Jaya, Muara Dua, Padang Jati, and Tengah Padang. Aedes aegypti dominated 36 urban villages, while Aedes albopictus dominated 26 urban villages. In conclusion, dengue vectors were distributed across all urban villages in Bengkulu City, with Aedes aegypti being the dominant species.
Analysis of the Incidence Rates of Dengue Hemorrhagic Fever Based on Land Cover, NDVI, and NDBI in Bengkulu City in 2018-2021 Lala Foresta Valentine Gunasari, Jonathan Farrel Pricaro, Yulian Fauzi, Dessy Triana Bio Web of Conferences, 2024 In 2022, the incidence rate (IR) of dengue in Indonesia was 34.33%, with environmental factors playing a role in its distribution. Changes in land cover can alter microclimatic conditions, such as rainfall and temperature, which indirectly affect the habitat, breeding, and activity of mosquito vectors This study employed a quantitative method with an ecological approach and a time series model to analyze land cover, the normalized difference vegetation index (NDVI), and the normalized difference built-up index (NDBI) in Bengkulu City between 2018 and 2021. Accuracy tests for each map involved 42 sample points, totaling 504 points overall. The samples were calculated using the overall accuracy and Kappa coefficient formulas assisted by a confusion matrix. Statistical tests, including multiple linear regression and classical assumption tests, were also carried out. The results indicated that the IR of dengue in Bengkulu City decreased from 2018 to 2021. The low-density category of NDVI had a nondirectional influence on the IR of dengue (-0,733), while the moderate-density category of NDVI had a unidirectional influence on the IR of dengue (0,487). NDVI simultaneously influenced the IR of dengue (R2 = 38%). Meanwhile, NDBI and land cover simultaneously and partially did not influence the IR of dengue. An increase in low-density NDVI areas reduced the IR of dengue, while a decrease in moderate-density NDVI areas reduced the IR of dengue (β = - 0.487).
Dengue Hemorrhagic Fever (DHF): Vulnerability Model Based on Population and Climate Factors in Bengkulu City Dessy Triana, Martini Martini, Ari Suwondo, Muchlis Achsan Udji Sofro Achsan Udji Sofro, Soeharyo Hadisaputro, Suhartono Suhartono Journal of Health Science and Medical Research, 2024 Objective: The causes for the increasing number of dengue cases are complex and multifactorial. The approach taken must combine influencing factors, and comprehensive prevention strategy is needed that includes all the components of factors that influence dengue disease to predict the incidence of the disease. This research aimed to analyze the relationship between population and climate components including population density, population density <15 years old, sanitation, temperature, humidity and rainfall, on the incidence rate of Dengue Hemorrhagic Fever (DHF).Material and Methods: This study used a cross-sectional design, with the research sample being all sub-districts in Bengkulu City, Indonesia (67 sub-districts). Data analysis was conducted using structural equation modeling to create a dengue modeling based on population and climate factors, through the SmartPLS application.Results: Population and climate factors had a significant relationship with the incidence rate of dengue, with p-values of 0.018 and 0.000, respectively. Population and climate factors had a percentage effect on the incidence rate of dengue (36.9%).Conclusion: Population and climate factors had an influence of 36.9% on the incidence of dengue. There were many factors affecting the incidence of dengue, so a more comprehensive modeling of the various influencing factors is needed. Dengue modeling is crucial as an early warning system for the early prevention of dengue outbreaks, so that the control strategies implemented can be more effective.
Soil-Transmitted Helminth Infection: The Severity of Anaemia and Learning Concentration Levels Dessy Triana, Galieh Riyasdi Fadhurrohman, Nurul Karima, Besly Sinuhaji, Wahyu Sudarsono Unnes Journal of Public Health, 2022 Soil-Transmitted Helminths (STH) is a worm infection with a prevalence of 1.5 billion people worldwide and is mostly found in preschool and school children. Worm infection can affect the level of concentration and the quality of children's learning which results in less optimal achievement within their potential. The purpose of the research was to determine the correlation between STH infection and anemia and the level of concentration in children grades II-VI of elementary school in Kampung Melayu Sub-district, Bengkulu City. The research conducted using an analytic observational with the cross-sectional design. The research took 215 students as samples with a stratified random sampling method. Feces specimens were examined by using Kato-Katz technique. Haemoglobin levels were measured by using the POCT method and students' concentration levels were tested by using the Bourdon Vos Test. The results showed a significant relationship between STH infection with the occurrences of anemia (p = 0.001; RP = 0.225) and very weak correlation strength between STH infection with the concentration level (p = 0.014; RP = -0.167). Worm infection in preschool and school children can cause anemia and nutrition deficiency which affect their growth and development, cognitive function, concentration levels and learning achievement. Continuous education and coordination with related institutions is necessary to carry out strategies for preventing and treating worms thoroughly.
Endemicity of dengue with density figure and maya index in Bengkulu city, Indonesia Dessy Triana, Lala Foresta Valentine Gunasari, Helmiyetti Helmiyetti, Martini Martini, Ari Suwondo, Muchlis A. U. Sofro, Miftahul Haniyah, Meilia Andini Open Access Macedonian Journal of Medical Sciences, 2021 BACKGROUND: One of the factors contributing to dengue’s endemicity is the density of the dengue vector, namely, Aedes aegypti as the primary vector and Aedes albopictus as the secondary vector. Bentiring and Kandang Limun villages are high endemic areas of dengue. AIM: This study aimed to determine the relationship between dengue endemicity and density figure (DF) and Maya index (MI) in Bentiring and Kandang Limun villages, Bengkulu city. METHODS: This study used a cross-sectional design. The sampling technique used proportionate stratified sampling. The sampling refers to the guidelines for dengue entomology surveys according to the WHO 1999 criteria. A total of 400 ovitraps were installed, 200 ovitraps inside the house and 200 ovitraps outside the house. RESULTS: The results showed that Bentiring and Kandang Limun villages had a high risk of dengue transmission based on entomological parameters, namely, ovitrap index (OI) 56% and 55% (DF 6), house index (HI) 45% and 44% (DF 6), container index (CI) 23% and 23% (DF 6), and BI 96% and 120% (DF 7 and 8). The areas have a high risk of dengue transmission based on the MI 71% and 76%, respectively. There is a relationship between dengue endemicity and entomological index in Bentiring and Kandang Limun villages, Bengkulu city, with a significance value (p = 0.000) and a powerful correlation (r = 1.000). CONCLUSION: There is a relationship between dengue endemicity and the MI in Bentiring village and Kandang Limun village, Bengkulu city, with a significance value (p = 0.014 and 0.058) and a powerful correlation (r = 0.920 and r = 1.000), respectively. The entomological index and DF are predictors for dengue prevention and control environment to minimize mosquito breeding sites and reduce disease transmission.
ENTOMOLOGICAL PARAMETERS AND CHARACTERIZATION OF INSECTICIDE RESISTANCE IN DENGUE VECTOR AEDES AEGYPTI LARVAE FROM BENGKULU CITY, INDONESIA Dessy Triana, Fitaloca N Siregar, Eka Purnama Wulan Tri Utami, Tatik Suteky, Swandito Wicaksono Malaysian Journal of Public Health Medicine, 2021 In Bengkulu, as in other areas of Indonesia, dengue is one of the most important vector-borne diseases. The primary strategy to control dengue is by reducing the vector population using insecticides. However, applications of insecticides becomes a contributing factor in the development of vector resistance. As there is no effective dengue drug or safe vaccine available, vector control remains the most effective intervention to reduce incidence and prevent transmission and outbreak. This study aimed to determine the entomological parameters and resistance status to temephos of Aedes aegypti larvae from Lingkar Barat village and Jalan Gedang village (dengue endemic areas). This study used cross-sectional and experimental with post-control only design. The sampling refers to the guidelines for dengue entomology surveys according to WHO 1999 criteria. Aedes aegypti eggs were collected by ovitraps and reared to larvae stage. Susceptibility test of larvae to the temephos was estimated using standard WHO. Mortality of larvae Ae. aegypti after 24 hours with multiple concentration of temephos indicative of highly resistant. Entomological parameters for house index (HI), container index (CI) and container pupa index (CPI) in Jalan Gedang village and Lingkar Barat village were estimated: 7%, 12% for HI and 1.97%, 3.43% for CI, and 5%, 2% for CPI, respectively. The proportion of controllable sites is higher than disposable sites, it has a high risk as breeding places for mosquitoes indicates a high potential risk as breeding place and transmission of dengue. Awareness sanitation in the home and surrounding environment must be possessed by each individual community in order to prevent and overcome the incidence of dengue. These data should be of value in formulating dengue control programs.
