Abstract

Background: The strengthening of health behavior intentions in disaster mitigation poses an urgent challenge to be addressed. There is a need to enhance health behavior preparedness in facing disaster threats, considering that the city of Palu is located in an earthquake-prone zone and has a history of being affected by earthquakes. This research aims to study health behavior and mental health in relation to disaster vulnerability, based on a case study of Huntap in the Tondo area, Palu City, Central Sulawesi, using the Theory of Planned Behavior (TPB) approach. Method: The type of research used is a mixed-method approach with a sequential explanatory model. Data collection utilizes questionnaires and observation sheets, supplemented by interview methods in the qualitative approach. Result: This study shows that the chi-square test results indicate a significant relationship between attitude, subjective norms, behavioral control, and mental health (<0.05) with health behavior. Meanwhile, in-depth interviews revealed barriers to health behavior, such as respondents' attitudes towards preparedness efforts and inadequate access to information and health workers. There is a pressing need for mental health interventions to improve preparedness. Moreover, there is a need for mental health interventions to improve mental health in promoting disaster preparedness efforts. Conclusion: This study concludes that mental health related to disaster vulnerability among the Huntap Tondo community is still lacking, which will impact disaster preparedness. Mental health interventions are essential to enhance preparedness and reduce disaster-related losses. Therefore, mental health interventions are needed to enhance preparedness for disasters and take action to reduce disaster losses and damage.

Abstract

In present study, video images technique is used to investigate the transformation of the directional wave spreading in shallow water. The technique is based on time series of the pixel brightness on video images. The Bayesian Directional Method is conducted in estimating the directional wave spectrum for evaluating the change of the directional wave spreading in the surf zone area. Video image data recorded at Hasaki beach in Japan are used in the analysis. Estimation of principle direction and spreading parameter in the surf zone regions indicated that principle directions at peak frequency are not strongly affected by wave breaking process. In contrast, the broadenings of directional spreading were observed when the waves start breaking on the sand bar and toward the shore area.

Abstract

The problems in port infrastructures related with climate change, especially sea level rise, have continued to receive a high level of attention. Knowledge of climate change should become a major interest for engineer, stakeholders, and decision makers or the port authorities in port industry for developing mitigation and adaptation strategies in the future. The objective of this paper is to measure sea level change in the Indonesian sea from satellite altimetry. In this study, satellite altimetry mission of Jason-2 are used to obtain altimetry data from NOAA server databse. These data are processed by using software Basic Radar Altimetry Toolbox (BRAT). Analysis of sea level change is done for 4 years period from 2009 to 2012 in 4 locations, which are Medan, Pemangkat, Ambon, and Manokwari. The results showed that the highest sea level rise is in Manokwari 14.10 mm/year, and the lowest is in Ambon with trend of sea level rise 1.17 mm/year.

Abstract

This study investigates the capabilities of optical remote sensing to monitor bathymetry in nearshore area using video images. The technique is designed to extract wave number components based on variation of intensity of brightness at each pixel in the images using cross-spectral correlation approach. This approach is based on pixel array analysis that utilizes a nonlinear inverse method 'Levenberg-Marquardt’. The technique is applied to the data collected at Hasaki beach in Japan from August to December 2006. The results indicate that the cross-spectral correlation approach have the capability to derive wave number estimate from time series data of video images with small rms errors (0.0342-0.0421). Also, the estimate of nearshore bathymetry is proved reasonable accurate near shoreline and breaking area where the differences between estimated and survey water depth are less than 10-30 cm.

Abstract

This study aims to analyze global wave climates of present and future time by using the WAM model. The analysis is performed based on wind climate data from the JMA/MRI-AGCM3.2 climate change projection. We analyze two 6-hourly wind data sets, covering two periods: the present climate ranging from 1979-2003 and future climate extending from 2075-2099. These wind data are used to implement the WAM model for producing the outputs of wave characteristics. Subsequently, the outputs from each period were used to study global wave climate in the future. The analysis showed that the wave climate is strongly dependent on the geographical position of regions from mid to high latitude and low latitude. This includes regions where the climate induced changes for present to future climate. The largest increases of significant wave height which reached approximately 5% occur in the southern parts of the Indian, Pacific and Atlantic Oceans and in the Antarctic Ocean. The decreases in the same magnitude around 5% occur especially in the North Atlantic Ocean.

Abstract

Sea level rise, as one of the consequences of global climate change, has significantly impacted oceanographic dynamics, particularly wave characteristics. One of the most critical affected parameters is significant wave height, which directly influences maritime safety, the sustainability of fisheries, the stability of coastal infrastructure, and the risk of coastal erosion and tidal flooding. As an archipelagic nation with the second-longest coastline in the world, Indonesia is highly vulnerable to such changes. Therefore, understanding the spatial and temporal trends in significant wave height is essential to support effective adaptation and mitigation policies in coastal regions. This study aims to analyze the trend of increasing significant wave height in Indonesian waters using ERA5 reanalysis data from the European Centre for Medium-Range Weather Forecasts (ECMWF) over the period from 1980 to 2020. The trend analysis was conducted using non-parametric statistical methods, namely the Mann-Kendall test to detect statistically significant trends and Sen’s Slope Estimator to quantify the rate of change. A significance level of 0.05 was applied in the analysis. The results indicate a significant upward trend in significant wave height across several Indonesian maritime regions. Conversely, the northern waters of Central Java and the northern region of Masalembu Island exhibited no statistically significant trend across seasons. The Banda Sea and southern Papua experienced significant increases during the dry season (JJA) and the second transitional season (SON), with a peak rate of 1.70 cm/year. In the southern waters of Lombok Island, positive trends were observed in the wet season (DJF) and the first transitional season (MAM), with rates reaching 1.46 cm/year. The highest trend was recorded in the southern waters of Java during the wet season (DJF), at 1.72 cm/year. These findings suggest that most Indonesian waters are experiencing significant changes in wave characteristics as a result of climate change, highlighting the urgency for long-term oceanographic monitoring and the integration of wave data into coastal development and climate adaptation strategies.

Abstract

Chayote for farmer groups is currently only a commodity that is directly marketed, but with an abundance of production it makes farmers lose money due to lack of demand and difficult marketing places, so there is a need for innovation in suppressing the abundance of chayote production in preventing spoilage. This service aims to provide community understanding and skills in processing chayote plants into healthy food to improve the immune system. The methods of the activities carried out are: Counseling on the importance of diversification (diversification) of processed chayote products into biscuits made from chayote flour, to increase product added value, product shelf life and increase community income of chayote farmer groups. The results achieved from the training in making dodol and chayote-based brownies can improve the health and welfare of the people of Gumbasa sub-district, Sigi Regency, especially PKK women in Pandere village. The results of this service activity can increase community knowledge and skills, in mobilizing potential resources in the form of chayote owned by the community to increase income and community welfare based on technological innovation and local wisdom.
