Dengue hemorrhagic fever (DHF) has become an endemic in major cities in Indonesia. The climate change and poor level of awareness and knowledge of the community in Indonesia have caused an increase in the DHF cases. Outbreaks on January until April 2015, the morbidity rate reached 50.75. In 1996, the Intergovernmental Panel on Climate Change (IPCC) predicted threefold increase in the dengue hemorrhagic fever incidents in Indonesia by 2070, if the environment and community conditions do not improve. This study aims to provide a dynamic model to predict the dynamics of the DHF incidents based on climate variability in the Special Capital Region of Jakarta. The design of this study was ecologic study with hypothesis test, modelling, simulation, and intervention. In collecting the data, interview with respondents and measurement of climate variables were conducted. Interviews with respondents include the level of knowledge, attitudes, and behaviour (PSP) of the community. Measurements of climate factors include rainfall, temperature, humidity and CO2 level in the ambient environment. The DHF system dynamics model simulation shows that the significant effect on the decline of Breeding Places and the decrease of DHF cases were achieved by increasing the participation of the community to actively control water places that are potential for mosquito breeding places.

Solenoids have been made with square and triangular cross-sections. Both kinds of solenoids are made with an iron core and without an iron core. The solenoids specification were 12 cm long and 3.5 cm wide with 220 windings and 900 windings. The iron core specification was 12.5 cm long and 8 mm diameter. The induction voltages both of solenoids have calculated with experiments method in the laboratory. Calculation of induction voltages with the experiment method used the motor as the magnetic drive, full-wave rectifier circuit, neodym magnet, and led lamp. Induction voltage and electric current obtained of each solenoid for range from two cm until ten cm. The closest distance between the solenoid with the motor as magnetic drive and the greater the number of solenoid windings produced the greater the induction voltages. Triangular-sided solenoids with 220 windings produced faster induction voltages than the square-sided solenoid for the same number of windings. While an iron core solenoids produced faster induction voltages than solenoid without an iron core.

A low number in green building development cause the building construction will have an immense direct and indirect impact on future generations. This paper identified the optimum incentive model driving the building efficiency achievement in green building operation and maintenance. Critical factors that influence building consultant and contractor decision in green building design and construction toward the operation and maintenance achievement planned were analysed using partial least square structural equation modelling (PLS-SEM) methods. Precisely, the study modelled the regional policy affecting building efficiency achievement in the developing country. This research already identified the way of green building stakeholders' operations and maintenance in the capital city of Indonesia. Quantitative method using case study analysis already validated for the questionnaire data. The PLS-SEM indicated that sustainable in green building implementation and sustainability has significant causal effects on the regional policy of building the life cycle. Among these factors, tax exemption, expedited permit, and floor to area ratio were significant. The regional policy indicators in green building implementation have the most significant effect on building efficiency achievement.

Role of green building developer and owner in sustainability construction: investigating the relationships between green building key success factors and incentives

引用

IOP Conference Series: Earth and Environmental Science 2020年第1期426卷

Adaptation to the concept of sustainability is a problem in developing countries, especially in terms of the level of knowledge, economic capability, environmental conditions, and regional policies. These four aspects become exogenous variables in this study to examine the role of green building concepts in sustainable concepts in building construction. Qualitative and quantitative methods become a way to prove the hypothesis of this study by using SEM-PLS as an analysis tool. The sample in this study limits the building developers and owners to assess aspects that affect the sustainability of the green building concept and obtain an overview of the incentive models they expect. The results of this study indicate the level of knowledge of building developers and building owners affects the ability of building management to achieve a sustainable concept. Besides, the aspect of sustainability has an impact on the acquisition of both internal and external incentives for developers and building owners. Specific incentive models that developers and owners expect are accelerating licensing and building certification and reducing property tax. The government also supports the provision of property tax compared to value-added tax because it is a controlling tool in implementing green building concepts.

Indonesia and Malaysia are neighboring countries that situated in a tropical area and suitable for weathering, particularly favorable for lateritic deposit. One of laterite deposit is bauxite, where bauxite was formed as a chemical weathering product of metaluminous to peraluminous igneous rocks. The study area is located in the Kuantan area, Pahang State, Malaysia and West Kalimantan Province, Indonesia, which has contrasting tectonic origin and serve a different parent rock of bauxite. This study aims to distinguish the geochemical characteristics of bauxite in West Kalimantan against bauxite in Pahang Province. Method used in this study consists of pitting examination, where samples were collected from surface to maximum 10 m intervals and vertically logged. Samples were analyzed petrographically, XRD and XRF in order to observe the mineralogical composition and chemical compound. Result shows that magmatism in Pahang is dominated by basalt with oxide concentration of Al2O3, Fe2O3, SiO2 and TiO2 respectively ranges from 43.96 - 51.01%, 16.59 - 18.97%, 2.17 - 9.01% and 2.83 - 2.91%. In Indonesia, the parent rock of andesite and diorite (Al2O3 = 48.11 - 53.49%;Fe2O3 = 6.15 - 17.25%) shows higher amount of Al2O3 than that in granodiorit (Al2O3 = 30.10 - 48.68%). It can be inferred that andesite and diorite as bauxite's parent rock found in Kalimantan Barat generates abundant gibbsite and higher proportion of Al2O3 with lesser goethite and hematite (Fe2O3) relative to basalt as bauxite's parent rock in Pahang. © Published under licence by IOP Publishing Ltd.
