Abstract

Inadequate planning, housing, water, sewage, and waste management in urban and semi-urban areas produced ideal conditions for dengue viruses and their mosquito vector Aedes Aegypti to spread throughout the region over the preceding decade. Dengue prevention is primarily focused on vector control (chemical spraying, biological control, physical removal of breeding grounds, and infrastructure enhancement) and community education in the absence of a vaccine. They have not influenced the prevalence of Dengue Hemorrhagic Fever (DHF) Public health surveillance is the systematic and continuous collection of data and information on events, health problems, and conditions that influence the occurrence and spread of disease to plan, implement, and evaluate public health practices. It is crucial in dengue management since it determines the number and distribution of cases, viral serotypes, and severity of disease in a community. The purpose of this article is to examine the use of Geographic Information Systems (GIS) to determine the spatial distribution of the DHF Risk map in the Gorontalo Regency. The GIS system's overlay operation is utilized to combine two maps, namely the DHF hazard map and the DHF vulnerability map. The findings reveal that the Gorontalo Regency is dominated by low-risk classes, with a total area of 99,716.7 ha (46.52%). The GIS approach might be used to assess transmissible DHF risk zoning, which would aid in enhancing DHF and other vector-borne disease surveillance strategies to promote prevention and control efforts.

Abstract

One method of reducing the spread of dengue hemorrhagic fever (DHF) is to provide a map of DHF-prone locations based on spatial analysis. The major way to prevent the spread of DHF is to manage and control its vector by focussing on specific regions of localisation and removing appropriate breeding circumstances. Spatial analysis can detect DHF clusters that are larger than expected based on the underlying data. This research aimed to identify and map DHF vulnerability zones based on many parameters within the scope of the analytical hierarchy and geographical information systems (GIS). We found that the consistency ratio of 0.079 for analytic hierarchy process (AHP) factor weights was judged to be satisfactory. The population density, distance to the road, and distance to health facilities were shown to be the most relevant factors in determining DHF vulnerability. Gorontalo Regency is dominated by low vulnerability classes with an area of 139,493.5 ha or 65.08% of the total area. The GIS-AHP process could be used to assess transmissible DHF vulnerability zonation, which would aid in improving surveillance strategies for DHF and other vector-borne diseases in order to encourage prevention and control actions.

Abstract

Mapping of potential flood hazards is an important element in ensuring proper planning of development and implementing flood disaster mitigation efforts for flooded areas. Therefore, this study was conducted to assess the regional-scale flood hazard areas in Gorontalo District using an AHP-GIS integration technique with the focus on factors such as annual rainfall, elevation, slope, soil type, distance to the water bodies, and land-use. The flood hazard was divided into five classes, ranging from very low to very high, and 13.61% of the total area in Gorontalo Regency is classified as either high or very high. Moreover, the distribution of the hazard was verified and 65 events were recorded to have a level of 90.7% and this indicates the model is reliable to assess flood hazard. The results showed GIS-AHP integration is a promising method to accurately predict flood-hazard areas, especially in those with limited data.

Abstract

Under certain climatic conditions, Aedes aegypti and Aedes albopictus mosquitoes can survive and reproduce optimally so that climate change can significantly change the pattern of disease distribution. This study aimed to model the level of Dengue Haemorrhagic Fever (DHF) hazard in Gorontalo Regency by integrating the Analytical Hierarchy Process (AHP), Geographic Information System (GIS) with climatological and topographic factors. The factors that most influence the level of hazard of DHF are annual rainfall, altitude, and humidity. The results obtained show that Gorontalo Regency is dominated by the hazard level class of 94852.31 ha or 44.25% and the moderate class area of 82553.37 ha or 38.5% of the total area of Gorontalo Regency. These results prove that Gorontalo Regency is very at risk of DHF disease. If this is not handled by the government properly, the moderate class will potentially rise to the high class. The prediction model for the DHF hazard level in this study can be made according to local conditions in the research area which have limited data. Changes in climate variables and periodicity that affect the incidence of dengue can be flexibly adapted to this model. The findings from this study provide valuable insights that have the potential to improve mitigation in public health-related interventions.

Abstract

Several regions across the world are presently experiencing a continuous increase in water scarcity due to the rise in water consumption resulting from population development, agricultural and industrial expansion, climate change, and pollution. Droughts are increasing in recurrence, severity, duration, and spatial extent as a result of climate change. Drought will be one of the most serious threats posed by climate change, often in conjunction with other effects such as rising temperatures and shifting ecosystems. Therefore, this study analyzes the spatial distribution of the Drought Hazard Index (DHI) by integrating AHP-GIS-Remote Sensing in Gorontalo Regency. AHP was used to determine the significance of each map as an input parameter for the DHI, while GIS-Remote Sensing was utilized to supply and analyze all input maps and the study outcome. The DHI assessment consists of four criteria, namely with Normalized Difference Vegetation Index accounting for the highest proportion at 42.9%, followed by Land Surface Temperature (33.6%), Normalized Difference Moisture Index (16.8%), and Topographic Wetness Index (6.7%), with the consistency of the underlying expert opinion measured by the consistency ratio of 0.048. The results indicated that the general hazard of drought in the Gorontalo Regency area was low (43.53%), with 17.87% of the whole area experiencing high hazard. The high class of drought was discovered to be centered in the central region of Gorontalo Regency, which was mostly used for agricultural and economic purposes, thereby enabling policymakers to have evidence to develop management policies suitable for local conditions. Therefore, despite the limits of climatology data, this study established the value of satellite-derived data needed to support policymakers in guiding operational actions to drought hazards reduction.

Abstract

Perkembangan infrastruktur berbanding lurus dengan tingkat kebutuhan akan semen sebagai bahan utama dalam konstruksi bangunan. Industri semen menghasilkan 8-10% dari total emisi CO2 dunia. Penelitian ini bertujuan untuk menemukan alternatif atau penggantian sebagian material beton hijau sehingga meminimalkan dampak lingkungan dari pembuatan beton dan meningkatkan kekuatan beton, salah satunya adalah fly ash. Fly ash dapat digunakan bersama dengan semen portland dalam beton yang berkontribusi terhadap sifat-sifat beton melalui aktivitas hidrolik atau pozzolan, atau keduanya. Hasil pengujian kuat tekan karakteristik beton dengan substitusi parsial semen dengan variasi fly ash (9%, 9.5%, 10%, dan 10.5%) pada umur 28 hari adalah masing-masing 36.70 Mpa, 35.11 Mpa, 33.37 Mpa, dan 30.38 Mpa. Kuat tekan beton meningkat sebesar 5% pada variasi fly ash sebesar 9% dan 9.5% dan menurun sebesar 13% pada variasi fly ash sebesar 10% dan 10.5%. Dari hasil tersebut dapat disimpulkan bahwa semakin besar persentase penggunaan fly ash sebagai subtitusi parsial semen maka semakin menurun kuat tekannya. Jumlah optimum fly ash bervariasi sangat bergantung pada komposisi dan proporsi semua bahan dalam campuran beton (terutama fly ash), kondisi selama penempatan (terutama suhu), praktik konstruksi (misalnya, finishing dan curing) dan kondisi paparan. Dengan demikian, kadar fly ash yang optimal akan bervariasi berdasarkan kasus per kasus.
