Purposes: The study aimed to translate the Exercise Self-Efficacy Scale (ESES) into Indonesian and test the cultural equivalence, reliability, and validity of the new version for university students. Methods: The cross-sectional study recruited 379 Indonesian university students using convenience sampling. Phase 1, a culturally appropriate version of the ESES was developed in the Indonesian language. Phase 2, the psychometric properties were determined through exploratory factor analysis, bootstrap factor analysis, and confirmatory factor analysis. The internal consistency reliability was tested using Cronbach's a, whereas the stability using intraclass correlation coefficient to assess. Results: The students' ages ranged from 17 to 39 years, and 65.0% were women. For translation equivalence, the mean item content validity indexes ranged from 3.5 to 4, and all items were understandable. The 16-item scale exhibited cross-cultural appropriateness and readability, with a three-factor model explaining 62.3% of the variance in exercise self-efficacy. A bootstrap analysis using 100 resamples further confirmed the three-factor model. The indices of the good-fit model that used the three-factor by two-stage least squares method were satisfactory, with c2/df ¼ 3.3, goodness of fit index = .88, and root mean-square error of approximation = .05 (p < .001). The Cronbach's a was .78, .80, and .92 for factors 1, 2, and 3, respectively. The test–retest reliability was demonstrated with an intraclass correlation coefficient of .91, indicating adequate measurement stability. Conclusion: The 16-item ESES-I has acceptable validity and reliability; however, a broader application of the scale requires further testing in different populations to confirm its external validity.

In this study, the antioxidant activities of juice,peel, and seed parts of pomegranate were investigated by using DPPH scavenging activity, β-carotene bleaching method, reducing power, and metal chelating activity. Sample of pomegranates which are named Punica granatum L. cv. Hicaznar, genotype 19-121, genotype 17-67, and genotype 19-66 obtained from BATEM (West Mediterranean Agricultural Research Institute) in Anlalya. The EC50values of DPPH scavenging activities in peel extracts (PE)had 23.4-fold higher than the juice extracts (JE), and the seed extracts (SE) had 2.3-fold higher than JE. The reducing power in peel extracts was found to be 4.7-fold higher than SE and 10.5-fold higher than the JE. The highest metal chelating capacity (37.22%) was determined in peel, while the lowest (7.151%) in seed. Generally, in peel, the total polyphenol, flavonoid, tannin contents, and in juice, the total polyphenol, anthocyanin, tannin contents,and acidity significantly affected to antioxidant activities.

A Review on Remote Sensing and GIS Applications to Monitor Natural Disasters in Indonesia

Hakim, Wahyu Luqmanul,Lee, Chang-Wook The Korean Society of Remote Sensing 2020 大韓遠隔探査學會誌 Vol.36 No.6

Indonesia is more prone to natural disasters due to its geological condition under the three main plates, making Indonesia experience frequent seismic activity, causing earthquakes, volcanic eruption, and tsunami. Those disasters could lead to other disasters such as landslides, floods, land subsidence, and coastal inundation. Monitoring those disasters could be essential to predict and prevent damage to the environment. We reviewed the application of remote sensing and Geographic Information System (GIS) for detecting natural disasters in the case of Indonesia, based on 43 articles. The remote sensing and GIS method will be focused on InSAR techniques, image classification, and susceptibility mapping. InSAR method has been used to monitor natural disasters affecting the deformation of the earth's surface in Indonesia, such as earthquakes, volcanic activity, and land subsidence. Monitoring landslides in Indonesia using InSAR techniques has not been found in many studies; hence it is crucial to monitor the unstable slope that leads to a landslide. Image classification techniques have been used to monitor pre-and post-natural disasters in Indonesia, such as earthquakes, tsunami, forest fires, and volcano eruptions. It has a lack of studies about the classification of flood damage in Indonesia. However, flood mapping was found in susceptibility maps, as many studies about the landslide susceptibility map in Indonesia have been conducted. However, a land subsidence susceptibility map was the one subject to be studied more to decrease land subsidence damage, considering many reported cases found about land subsidence frequently occur in several cities in Indonesia.

Efficient smoothed particle hydrodynamics method for the analysis of planar structures undergoing geometric nonlinearities

Hakim Naceur,Jun Lin,Daniel Coutellier,Abdel Laksimi 대한기계학회 2015 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.29 No.5

In the present investigation, a new modified smoothed particle hydrodynamics (SPH) method particularly adapted for the analysis ofplanar structures undergoing geometric nonlinearities is introduced and discussed. The problem of inconsistency which is often encounteredin the classical SPH method is alleviated by introducing modifications of the kernel function and its derivatives using an explicitpolynomial feature representation based on the Taylor series expansion. Tensile instabilities arising in the Eulerian-based SPH formulationwhich appear due to large deformations are attenuated by the introduction of a total Lagrangian formulation which is robust for largedisplacements/rotations. The resulting nonlinear problem is solved using the explicit dynamics time integration scheme. The validity ofthe proposed approach is demonstrated through two numerical applications involving geometrical nonlinearities, where the obtainedresults are compared to those obtained using the standard finite element method.

How the DOHA Round Could Support the African Industry?

Hakim Ben Hammouda,Stephen Karingi,Nassim Oulmane,Mustapha Sandi Jallab 중앙대학교 경제연구소 2007 Journal of Economic Development Vol.32 No.1

This study provides a quantitative evaluation of the Doha Round in terms of the market access for industrial products and the possible consequences of the trade liberalization process. It analyzes the impact of the reforms put forward by the July Package concluded in Geneva. The tariff reduction scenarios under review fit in with the commitments undertaken in the July Package. All four scenarios reviewed are based on a Girard formula. The first, third and fourth scenarios are ambitious, whereas the second is more conservative. Scenarios 1, 3 and 4 differ in the way they factor in special and differential (S&D) treatment. In terms of impact, the simulations show that a liberalization scenario based on an ambitious, non-linear Girard formula would be a less desirable alternative for Africa. It would allow for increases in the welfare and production of the African countries but would not boost African exports.

ANN Modeling of a Gas Sensor

Hakim BAHA,DIBI Zohir 대한전기학회 2010 Journal of Electrical Engineering & Technology Vol.5 No.3

At present, Metal Oxide gas Sensors (MOXs) are widely used in gas detection because of its advantages, including high sensitivity and low cost. However, MOX presents well-known problems, including lack of selectivity and environment effect, which has motivated studies on different measurement strategies and signal-processing algorithms. In this paper, we present an artificial neural network (ANN) that models an MOX sensor (TGS822) used in a dynamic environment. This model takes into account dependence in relative humidity and in gas nature. Using MATLAB interface in the design phase and optimization, the proposed model is implemented as a component in an electronic simulator library and accurately expressed the nonlinear character of the response and that its dependence on temperature and relative humidity were higher than gas nature.

Cultural Landscape and Ecotourism in Bali Island, Indonesia

Hakim, Luchman,김재은,홍선기 한국생태학회 2009 Journal of Ecology and Environment Vol.32 No.1

This paper describes the role of ethnoecology in supporting tourism. We conducted a case study on the island of Bali (Indonesia), the famous tourism destination. We review the culture, nature and ecotourism prospects of Bali and then extend our discussion to examine the role of indigenous philosophies in building the destination’s image. Bali has a rich culture and natural resources that have been utilized and managed through an indigenous philosophy called Tri Hita Karana. Ethnoecology is widely applied and appreciated in the society and has produced Balinese cultural landscapes that have become significant tourism attractions. There has been a recent increase in tourist desire to explore genuine Balinese culture, so ethnoecology has a significant role in the quest to preserve and conserve such indigenous cultural landscapes. Ethnoecology is a key to ensuring and sustaining the images and authenticity of Bali Island. In this paper, we considered the landscape of rice paddies as a cultural landscape and resource for tourism. The structure and function of paddy terrace landscapes is based on the ethnoecology of Tri Hita Karana; therefore, in order to understand nature and ecotourism in Bali Island, knowledge of indigenous philosophy is indispensable. Cultural landscapes that link human and natural systems are not only places of natural beauty but also provide background information about the history of human adaptations to nature.

Hakime Hulya Orak,Sebnem Selen Isbilir,Hulya Yagar 한국식품과학회 2012 Food Science and Biotechnology Vol.21 No.4

The objective of this study was to compare the antioxidant activities of lyophilized olive leaf water extracts (OLWExtracts) from 21 different olive tree cultivars. The highest total phenolic content (102.69±1.63 μg GAE/mg extract) was found in cultivar ‘Esek Zeytini’ and the lowest content (78.52±2.18 μg GAE/mg extract) was in ‘Uslu’. The highest total flavonoid content (12.47±0.12 μg QE/mg extract) obtained from ‘Frantoio’. According to EC50values, ‘Domat’ have the highest DPPH scavenging activity (EC50 =59 μg/mL), reducing power (EC50 =180 μg/mL),and superoxide radical scavenging capacity (EC50=44 μg/mL). While, ‘Ascolana’ showed the highest metal chelating capacity (EC50=163 μg/mL), ‘Memecik’ showed the highest hydrogen peroxide (H2O2) scavenging capacity. Research results exhibited that OLWExtracts are comparable to synthetic antioxidants. The correlation study showed that while total phenolic content correlated with DPPH scavenging activity and reducing power (p<0.01), total flavonoid content correlated with metal chelating and superoxide radical scavenging capacity (p<0.05).
