Does Natural Disasters Have an Impact on Poverty in East Java, Indonesia?
Dwi Budi SANTOSO(Dwi Budi SANTOSO ),Dynda Fadhlillah AULIA(Dynda Fadhlillah AULIA ) 한국유통과학회 2023 The Journal of Asian Finance, Economics and Busine Vol.10 No.1
There is a strong association between poverty levels and the probability of natural disasters. East Java, however, exhibits a distinct pattern. While the rate of poverty is declining, natural disasters are becoming more severe. Considering that East Java is an area with a high risk of natural disasters and a high poverty rate, this study aims to estimate the effect of environmental preservation and the magnitude of the impact of disasters as measured by the Disaster Risk Index (IRBI) on poverty. The 3SLS model is used on secondary data from 38 districts/cities from 2015 to 2021 as an analytical database. Based on the estimation results, there are 3 findings in this study: (i) the role of government, population development, and economic activity have a strong influence on nature conservation; (ii) nature conservation has a strong influence on disaster risk; and (iii) the disaster risk index has a strong effect on poverty. As a result, areas with a high level of disaster risk have a slower rate of poverty reduction. The role of this research is to show the need for the government’s role in improving the quality of natural disaster mitigation anticipation, economic activity, and the role of the population in a sustainable manner.
The connected size Ramsey number for pair of matchings and small paths

The connected size Ramsey number of a graph G and H, denoted by ^rc(G;H) is the smallest integer ^rc such that there is a connected graph F of ^rc edges with the property that any red-blue coloring of the edges of F yields either a red subgraph G or a blue subgraph H: In this paper, we consider the connected size Ramsey number for a pair of a matching and a path. In particular, we derive an upper bound of ^rc(tK2; Pn) for n; t 2: We also determine the exact values of ^rc(tK2; Pn); for some xed n and t:

Purpose: This study examines the effects of several brand variables on customer satisfaction and brand loyalty. Research design, data, and methodology: The survey was conducted on a community with 302 city residents in Greater Jakarta as consumers of lighting products. The constructs were arranged based on several independent variables such as brand experience, brand relationships, and brand trust on customer satisfaction and brand loyalty. Customer satisfaction was positioned as an intervening variable to examine the effects on brand loyalty. Results: The consumer's experience determines the attitude and satisfaction at the next action. Brand experience significantly influences customer satisfaction and brand loyalty. Meanwhile, a brand association related to the benefits of the product concerned so that the relationship also affects customer satisfaction and brand loyalty. However, the brand relationship does not affect brand trust. Consumers do not readily believe without experience. Conclusion: The consumer's experience significantly influences satisfaction and brand loyalty, both direct and indirect. Brand relationships affected customer satisfaction and had a direct effect on brand loyalty. Likewise, brand trust has a direct effect on brand loyalty. The findings' implications emphasize the importance of brand owners to provide positive, memorable experiences to the consumers.

<P>A facile and green method to produce reduced graphene oxide (RGO) nanosheets based on supercritical alcohols is described. The obtained RGO nanosheets exhibited a high carbon-to-oxygen ratio (up to 11.89, determined by X-ray photoelectron spectroscopy), high electronic conductivity (up to 10 600 S m<SUP>−1</SUP>), and high lithium storage capacity with good cyclability (652 mA h g<SUP>−1</SUP> at a 50 mA g<SUP>−1</SUP> after 40 cycles) when tested as an anode material.</P> <P>Graphic Abstract</P><P>A green method to produce reduced graphene oxide nanosheets in supercritical alcohols is described. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c1gc15678k'> </P>
Characteristics of the Savonius Wind Turbine Using Multiple Guide Vanes

This paper aims at identifying the characteristics of the Savonius Wind Turbine using a guide vane, which functions as the steering mechanism and reduces the negative torsion on the returning blade. The addition of the guide vane did not influence the turbine’s capacity in receiving wind direction. The number of guide vanes varied from 4, 8, and 16 with an angle of 45°. The testing was conducted in a wind tunnel at the wind speeds of 4 ㎧, 5 m/s and 6 ㎧. The turbine with the additional 16 guide vanes gave the best result. The static torsion increased by 84%, dynamic torsion increased by 57%, and the coefficient of power increased by 58% a t the speed of 4 ㎧.
Effect of initial morphology on field performance in white jabon seedlings at Bogor, Indonesia
Budi Budiman,Dede J. Sudrajat,이돈구,김용식 한국산림과학회 2015 Forest Science And Technology Vol.11 No.4
Reforestation programs should be supported by adequate forest nursery techniques. Seedlings used for reforestation programs in Indonesia were based on the height of seedlings ready to be planted in the field without basic knowledge of seedling morphology. White jabon (Anthocephalus cadamba [Roxb.] Miq.), a potentially fast-growing multipurpose tree species, has been extensively planted for land rehabilitation and reforestation programs. The objective of this study was to determine the influence of seed viability and initial morphology (diameter and height classes) of A. cadamba seedlings on field survival and growth after planting at Parungpanjang Research Station, Bogor, Indonesia. Correlations were found between seedling characteristics at initial stages and survival or growth in the field: seed viability and seedling height; seedling diameter or survival rate in the field; and seedling height growth in both the nursery and field. Thus, more viable seeds may predict better seedling height growth, seedling diameter growth, and higher survival in the field after planting. The morphology class of H2D4 (height 20< 30 cm, diameter > 4.5 mm) was a good diameter and height class because of good sturdiness quotient of 5.47 and also high total dry weight of 3.05 g.

Modifications in the structural and magnetic properties of co-precipitated cobalt ferrite nanoparticles can be accomplished by varying the annealing time periods during the synthetic process. Experimental results show that high-purity cobalt ferrite nanoparticles are obtained using a co-precipitation process. The dependence of the crystallite sizes on the annealing time was successfully demonstrated using XRD and SEM. Finally, vibrating sample magnetometer analyses show that the magnetic properties of the cobalt ferrite nanoparticles depend on their relative particle sizes.
