No full textDetection of vehicle type based axle allow to do classify vehicle based on the load that will carried by the vehicle. However at this time, classification of heavy vehicle types based on axles is still carried out by humans. In here research, author use image processing for classification of vehicles class with PCA-K Nearest Neighbour Method. The reason for choosing this algorithm is because previous research use K-Means Clustering have a same formula with K-Nearest Neighbour. The data used is the image captured from the video camera processed by background subtraction method to separate moving object namely vehicle with its background. PCA method is required to obtain eigen vektor from vehicle and reduce its dimensions. Meanwhile, for classification author tries to use classification algorithm of K-Nearest Neighbour. To detect vehicle axles author use Circular Hough Transform method. The Testing Result shows detect vehicle type use PCA-K Nearest Neighbour method with value of K=1 has an accuracy 90%.Deteksi golongan kendaraan berdasarkan gandar memungkinkan untuk melakukan klasifikasi kendaraan berdasarkan beban yang akan di bawa oleh kendaraan tersebut. Namun pada saat ini, klasifikasi jenis kendaraan berat berdasarkan gandar masih dilakukan oleh manusia. Dalam penelitian ini, penulis menggunakan pengolahan citra untuk klasifikasi golongan kendaraan dengan metode PCA-K Nearest Neighbour. Alasan pemilihan algoritma ini adalah karena penelitian sebelumnya menggunakan algoritma K-means Clustering memiliki rumus yang sama dengan K-Nearest Neighbour. Data yang digunakan adalah citra yang ditangkap dari kamera video diproses dengan metode background subtraction untuk memisahkan objek yang bergerak yaitu kendaraan dengan backgroundnya. Metode PCA diperlukan untuk mendapatkan vektor eigen dari kendaraan dan mereduksi dimensinya, sedangkan untuk klasifikasi penulis mencoba menggunakan algoritma klasifikasi K Nearest Neighbours. Untuk deteksi gandar kendaraan penulis menggunakan metode Circular Hough Transform. Hasil pengujian menunjukkan deteksi golongan kendaraan menggunakan metode PCA-K Nearest Neighbours dengan nilai K=1 mendapat akurasi 90%.84 HalamanSkripsi Sarjan
Penggunaan Kaedah Riwāyat Bi Al-Maʿna dalam Pengriwayatan Hadis-Hadis Motivasi di Malaysia: The Use of Riwāyat Bi Al-Maʿna in Narrating Motivational Hadiths in Malaysia
No full textNabi Muhammad SAW merupakan seorang pakar motivasi yang hebat. Penghayatan dan pengamalan terhadap tutur kata dan perbuatannya mendorong setiap individu untuk melakukan kebaikan. Justeru, ramai pemberi motivasi Islam yang menjadikan Nabi Muhammad SAW sebagai qudwah dalam ucapan, pengajian atau modul motivasi yang mereka sampaikan. Bertitik tolak dari itu, kaedah riw?yat al-?ad?th bi al-Ma?na sudah menjadi norma kebiasaan para penceramah motivasi yang menggunakan hadis Nabi Muhammad SAW demi untuk memudahkan sesi penyampaian mereka. Namun, para ulama menggariskan syarat-syarat yang tertentu bagi tujuan tersebut kerana khuatir akan implikasi negatif sekiranya tidak mematuhi syarat-syarat tersebut. Justeru, kertas kerja ini akan mengupas berkenaan perbahasan para ulama hadis berkaitan riw?yat bi al-Ma?na serta menganalisis penggunaan kaedah riw?yat bi al-Ma?na dalam pengriwayatan hadis-hadis motivasi di Malaysia. Metodologi yang digunakan adalah secara kualitatif dengan melakukan analisis kandungan secara tematik terhadap kajian para ulama berkaitan riw?yat bi al-Ma?na serta menganalisis hadis-hadis berkaitan motivasi dalam ceramah rancangan motivasi di Malaysia. Kajian mendapati, penggunaan kaedah riw?yat bi al-Ma?na dalam hadis wujud dan menjadi satu norma kebiasaan bagi para penceramah motivasi. Pada sudut negatifnya, terdapat kesalahan dalam hadis-hadis yang digunakan berpunca daripada ketidak patuhan mereka terhadap syarat-syarat dalam melaksanakan kaedah tersebut. Tambahan pula, para pengkaji turut menghadapi kesukaran untuk melakukan proses takhrij dan penentuan darjat hadis-hadis di Malaysia disebabkan terjemahan Bahasa Melayu yang menyukarkan para pengkaji untuk mencari teks asalnya dalam Bahasa Arab. Pengkaji berharap agar lebih banyak kajian dilakukan berkaitan aplikasi kaedah-kaedah dalam hadis terhadap realiti bagi menjamin kesucian dan keaslian kalam Nabi SAW.
Abstract
Prophet Muhammad SAW was a motivational expert. By practicing his words and actions will encourage individual to do good. For such reason, many Islamic motivators take him as a qudwah in delivering their speeches, teachings or motivation modules. From that point, the method of narrating hadith with meaning has become the norm of Islamic motivational speakers in order to facilitate their delivery sessions. However, the Islamic Scholars did outline certain conditions for that purpose, fearing the negative implications if the speakers do not comply with those conditions. Therefore, this paper will examine the discussion of hadith scholars that related to riw?yat bi al-Ma?na as well as analyse the use of the method in the narration of motivational hadiths in Malaysia. The methodology in this paper is qualitative by conducting thematic content analysis on the study of scholars related to riw?yat bi al-Ma?na as well as analysing the hadiths taken from motivational talks in Malaysia. This study found that the use of riw?yat bi al-Ma?na in hadith exists and becomes a common norm for motivational speakers. However, there are some errors in the presented hadiths due to their non-compliance with the outline conditions. Furthermore, the researchers faced such difficulties in takhrij and determining the degree of hadith due to its translation in Malay language that makes it harder to identify the original text in Arabic. They are also hoping that more studies can be done regarding the practical of hadith in reality to ensure the Prophet Muhammad SAW’s words

No full textPurpose- The purpose of this study is to find the location of errors in students' Arabic speaking skills and then overcome these errors with the error analysis method, and this research focuses more specifically on showing the analysis of verbal errors.
Design/Methodology/Approach- The method used in this research is descriptive qualitative, data obtained from interviews, observations, and documentation at the Pondok Pesantren Nurul Jadid Probolinggo. This study used a sample of 7th grade students with a total of 30 students.
Findings— During the process of learning Arabic, especially speaking Arabic skills, students are not able to distinguish and pronounce the sounds of Arabic letters properly and correctly. This causes phonemic errors that occur in the students of the Nurul Jadid Probolinggo Islamic Boarding School during the Arabic learning process. There are many phonetic errors that are often found in speaking Arabic, including errors in pronouncing the letters. Arabic has long vowels and consonants that other languages like Indonesian don't have. There are even sounds that are close together and sounds that are firm are characteristics of Arabic which are often problematic in learning Arabic.
Research Limitation/Implications- Therefore the author divides from the mistakes made by the students to overcome them. This research could not be deeper because of the limited time given, even so this research got satisfactory results and it is hoped that it can help develop the maharah kalam learning process at the Nurul Jadid Islamic Boarding School Probolinggo
Prognostic factors for premature cardiovascular disease mortality in Malaysia: a modelling approach using semi-parametric and parametric survival analysis with national health and morbidity survey linked mortality data
No full textAbstract Background Cardiovascular disease (CVD) is the leading cause of premature mortality worldwide. Despite existing research on CVD risk factors, the study of premature CVD mortality in Malaysia remains limited. This study employs survival analysis to model modifiable risk factors associated with premature CVD mortality among Malaysian adults. Method We utilised data from Malaysia’s National Health and Morbidity Survey (NHMS) conducted in 2006, 2011, and 2015, linked with mortality records. The cohort comprised individuals aged 18 to 70 during the NHMS interview. Follow-up extended to 2021, focusing on CVD-related premature mortality between ages 30 and 70. We employed six survival models: a semi-parametric Cox proportional hazard (PH) and five parametric survival models, which were Exponential, Weibull, Gompertz, log-normal and log-logistic distributions using R software. The age standardized incidence rate (ASIR) of premature CVD mortality was calculated per 1000 person-years. Results Among 63,722 participants, 886 (1.4%) experienced premature CVD mortality, with an ASIR of 1.80 per 1000 person-years. The best-fit models (based on AIC value) were the stratified Cox model by age (semi-parametric) and the log-normal accelerated failure time (AFT) model (parametric). Males had higher risk (Hazard Ratio, HR = 2.68) and experienced 49% shorter survival time (Event Time Ratio, ETR = 0.51) compared to females. Compared to Chinese ethnicity, Indians, Malays, and other Bumiputera had higher HR and lower survival times. Rural residents and those with lower education also faced increased HRs and reduced survival times. Diabetes (diagnosed: HR = 3.26, ETR = 0.37; undiagnosed: HR = 1.63, ETR = 0.63), hypertension (diagnosed: HR = 1.84, ETR = 0.53; undiagnosed: HR = 1.46, ETR = 0.68), and undiagnosed hypercholesterolemia (HR = 1.31, ETR = 0.80) increased risk and decreased survival times. Additionally, current smoking and abdominal obesity elevated risk (HR = 1.38, 1.60) and shortened survival (ETR = 0.81, 0.71). Conclusion The semi-parametric and parametric survival models both highlight the considerable impact of socioeconomic status and modifiable risk factors on premature CVD mortality, underscoring the imperative for targeted interventions to effectively mitigate these effects
A fundamental CFD investigation of offshore structures for artificial coral reef development
No full textRigs-to-Reefs (R2R) is an alternative for oil and gas industry for decommissioning purpose. The program will benefit marine life as an artificial reef for a sustainable solution to promote ecosystem growth. For any oil platform considered for reefing, an extensive study on the suitability and performance of the artificial reef is essential. These studies will evaluate the stability and relevance of the structure as an artificial reef when deployed on the seabed. This paper presents the research on dynamic response and flow characteristics of a conceptual proposed R2R platform. The Computational Fluid Dynamics (CFD) simulation is intended to study the dynamic responses and flow characteristics analysis of a jacket oil platform for optimal settlement and growth of corals. Artificial reef performances were evaluated by calculating the performance indices of the upwelling and back eddy profile. It was found that the upwelling efficiency index is higher at current direction normal to the platform due to the higher frontal area exposed to the incoming flow. Meanwhile, back eddy efficiency index shows a significant low value for all directions. The CFD results presented will be discussed in terms of the possibility of better performance of an artificial reef which considering engineering and biological aspects
Factors associated with the severity of hypertension among Malaysian adults
No full textHigh blood pressure is a worldwide problem and major global health burden. Whether alone or combined with other metabolic diseases, high blood pressure increases the risk of cardiovascular disease. This study is a secondary data analysis from the National Health and Morbidity Survey 2015, a population-based study that was conducted nationwide in Malaysia using a multi-stage stratified cluster sampling design. A total of 15,738 adults ≥18-years-old were recruited into the study, which reports the prevalence of hypertension stages among adults in Malaysia using the JNC7 criteria and determinants of its severity. The overall prevalence of raised blood pressure was 66.8%, with 45.8% having prehypertension, 15.1% having Stage 1 hypertension, and 5.9% having Stage 2 hypertension. In the multivariate analysis, a higher likelihood of having prehypertension was observed among respondents with advancing age, males (OR = 2.74, 95% CI: 2.41–3.12), Malay ethnicity (OR = 1.21, 95% CI: 1.02–1.44), lower socioeconomic status, and excessive weight. The factors associated with clinical hypertension (Stages 1 and 2) were older age, rural residency (Stage 1 OR = 1.22, Stage 2 OR = 1.28), Malay ethnicity (Stage 2 OR = 1.64), diabetes (Stage 2 OR = 1.47), hypercholesterolemia (Stage 1 OR = 1.34, Stage 2 OR = 1.82), being overweight (Stage 1 OR = 2.86, Stage 2 OR = 3.44), obesity (Stage 1 OR = 9.01, Stage 2 OR = 13.72), and lower socioeconomic status. Almost 70% of Malaysian adults are at a risk of elevated blood pressure. The highest prevalence was in the prehypertension group, which clearly predicts a future incurable burden of the disease. Public health awareness, campaigns through mass and social media, and intervention in the work place should be a priority to control this epidemic.</div
Oxidation Behavior of AlxHfNbTiVY0.05 Refractory High-Entropy Alloys at 700–900 °C
No full textPublisher Copyright: © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.Refractory high-entropy alloys (RHEA) are considered as potential candidates for new-generation energy-related high-temperature applications. However, the poor high-temperature oxidation resistance of RHEAs, resulting in phenomena such as significant weight gain, scale spallation, pesting, and even complete oxidation, limits their applications. In this study, the oxidation behavior of AlxHfNbTiVY0.05 (x = 0.75; 1; 1.25) high-entropy alloys was investigated at 700–900 °C. The isothermal oxidation tests showed that the oxidation resistance of AlxHfNbTiVY0.05 RHEA is strongly influenced by temperature and time. In addition, accelerated oxidation, known as pesting, was observed to occur at 700 °C for all alloys; while, partial spallation was observed at 800 °C for the Al1 and Al1.25 alloys. Detailed analyses of oxidation kinetics have been carried out for the oxidation test series at 900 °C. The mechanism behind disintegration was investigated and attributed to accelerated internal oxidation followed by the formation of voluminous Nb2O5, TiNb2O7, and fast-growing AlNbO4, and is also thought to be related to the partial evaporation of V2O5.Peer reviewe
