GIS And Oil Spill Tracking Model in Forecasting Potential Oil Spill-affected Areas Along Terengganu and Pahang Coastal Area

Oil contamination can occur accidentally or incidentally in the environment as long as petroleum or shipping activities exist. There is a need to take appropriate preventive measures to reduce the negative impact by carefully monitoring the sprinkles and dispersion particles due to the oil spill movement. An expected oil spill originating from the Resak platform is positioned at 49.1 nautical miles from the Kuala Terengganu shoreline. The Dulang platform, positioned at 69.8 nautical miles from the Kuala Terengganu, can pollute the coastline of the Terengganu and Pahang ecosystems. This study aims; (i) make predictions from the direction of oil particle dispersion and (ii) engage the ecosystem to determine the effect of an oil spill on a platform around the coastal area. The combination of the Geographic Information System (GIS) and the Oil Spill Trajectory Model (OSTM) has been used to establish the appropriate response to locate the dense area of the slick. The result from the model running show in Northeast (NE) monsoon season, Terengganu and Pahang, have a high potential to affect. It is highly likely to reach the Terengganu coast area, especially in Dungun. It was predicted that 466 barrels of oil would arrive within four days of the December incident. Moreover, Kemaman and Pekan districts in Pahang also have the highest risk of being exposed to oil pollution during the Northeast Monsoon. This is due to the wind factors, which blow from South to North along the East coast of Malaysia Peninsular with a speed maximum of 13 ms-1 and indirectly carry the oil particles to coastal areas in Terengganu and Pahang

Identification of trends, direction of distribution and spatial pattern of tuberculosis disease (2015-2017) in Penang

In Malaysia, the annual tuberculosis (TB) cases exhibit a consistent upward trend, and Penang has experienced a similar increase since 2011. This research aims to analyze the trend, distribution direction, and spatial patterns of TB in Penang from 2015 to 2017, utilizing data from 4,015 TB cases obtained from the TB/Leprosy Unit of the Penang State Department. The study employs three analytical techniques: descriptive analysis, global Moran's I, and central feature with standard deviation ellipse, which measures the trend by calculating standard distances in the X and Y directions to identify the focus and movement of tuberculosis cases. The findings indicate a higher incidence of tuberculosis in males compared to females, with the age group of 45 to 64 years having the highest number of TB patients in Penang. The aging process contributes to weakened immune systems, facilitating tuberculosis development in this age group. The spatial pattern trends for the three study years (2015 to 2017) are scattered, as revealed by the Moran index, indicating a non-dynamic and clustered pattern of TB cases in Penang.The main center of TB case distribution is identified in the George Town subdistrict, situated in the Northeast district, particularly concentrated in urban areas. Rural areas exhibit lower TB cases. The standard deviation ellipse in the north to east direction suggests a potential risk of TB spread, especially to nearby neighborhoods, in the upcoming years

Faktor kesukaran dalam proses memodelkan sebuah tapak arkeologi menerusi pendekatan geospatial

Selama bertahun-tahun, ahli arkeologi telah bergantung pada peta dan analisis ruangan untuk memahami taburan artifak dan ciri di seluruh tapak arkeologi secara visualisasi. Walau bagaimanapun, pengenalan foto udara, penderiaan jauh digital, sistem maklumat geografi (GIS) dan sistem keletakan global (GPS) telah menyediakan ahli arkeologi dengan alat canggih untuk menganalisis dan menggambarkan taburan dan data arkeologi dengan cara yang inovatif. Oleh yang demikian, analisis geospatial telah mendapat pengiktirafan yang penting sebagai salah satu alat untuk membantu ahli arkeologi. Dengan menyepadukan foto udara, penderiaan jauh, GIS dan GPS ke dalam penyelidikan mereka, ahli arkeologi kini dapat menganalisis kuantiti data yang besar dalam masa yang sama memahami peranan ruangan. Ini telah membolehkan mereka memperoleh pandangan baru tentang taburan dan corak ciri arkeologi tersebut. Artikel ini bertujuan untuk mengkaji faktor kesukaran dalam proses memodelkan sebuah tapak arkeologi menerusi pendekatan geospatial. Antara faktor kepelbagaian yang menimbulkan kesukaran dalam proses memodelkan tapak arkeologi adalah tapak arkeologi, persekitaran, tingkah laku atau kelakukan dan faktor teknikal. Dengan kemajuan teknologi, pendekatan geospatial merupakan kaedah terbaik untuk penyelidikan arkeologi manakala ahli arkeologi perlu berhati-hati dan menimbang faedah dan cabaran yang berkaitan dengan analisis geospatial, memastikan kaedah ini digunakan secara berhemah dan beretika
