This article examines the literature study of the current situation of microplastic pollution in the marine ecosystems of Malaysia. The size, density, types of polymers, colour, and origins of microplastic in the ocean, coastal, and estuarine environments are all discussed in this article. ScienceDirect and Google Scholar search engines were used to collect, analyse, and sort the information. According to the literature search, the bulk of microplastics found in Malaysian ocean samples was between 100 and 5000 micrometres in size. The density of the microplastics discovered ranged from 0.88 g cm3 to 1.01 g cm3, which is lower than the density of seawater. In addition, the types of polymers were polypropylene, polyethylene, polyester, polystyrene, and polyamide. Red and transparent colour were two common colours found in the Malaysian ocean. The sources of microplastic such as industrial activities, anthropogenic activities, agricultural activities, and personal care products. Because microplastics can cause physical and chemical harm to marine species, pollute the natural environment, and negatively affect social and economic sectors, the critical information provided in this article may help government and non-government organizations develop strategic monitoring policies.
Perang modern saat ini telah bergantung pada informasi, peralatan tempur (tank) berperan penting selama masa perang, terlepas dari dimensi laras tank pemeliharaan setelah penembakan masih manual, dilakukan perhitungan dan pemilihan jenis pompa pada perencanaan sistem pembangkit tekanan pompa diperlukan untuk mengalirkan fluida. Metode perhitungan didasarkan pada tahapan perhitungan diameter pipa dan kecepatan fluida, kehilangan karena gesekan dalam pipa. Dari hasil perhitungan yang di lakukan di peroleh hasil diameter pipa 3 mm, head total pompa 1,8840 m, dipilih pompa sentrifugal, daya listrik 436 Watt, factor keamanan adalah 1,2, daya pompa serta kapasitas atau debit pompa dipilih pompa type 2HM5, dengan spesifikasi daya 0,6 HP, daya listrik 550 Watt, 220V/AC 50 Hz, 1 phase, jenis motor capasitor lowara type 2HM5. Kata kunci : Pompa, pipa, leopard.
Pancasila Value as the Final Solution to Eradicating Corruption. The word corruption is a word that is familiar to the people of Indonesia, both the lower, middle and upper classes of society. The perpetrators of corruption are thick-faced, they are not ashamed to wave and throw smiles in front of the camera. And become public consumption on the television. Corruption in Indonesia seems to flourish like mushrooms in the rainy season. This is evidenced by the many corruption cases that occurred on Indonesia. Based on legislation and institutions that prevent and eradicate corruption in Indonesia, Indonesia should be a country free from corruption. However, based on the 2015 corruption perception index released by Transparency International. The country of Indonesia is still in the order of 88 out of 168 countries surveyed. Pancasila has ethical values that are able to regulate the behavior of community life, nation and state in Indonesia. The importance of Pancasila as an ethical system is related to the problems of corruption that have plagued the Indonesian nation so that it can weaken the joints of the life of the nation and state.
To date, there has been limited knowledge on the applicability of the spline interpolation method to estimate coastal water quality parameters. This study aims to assess the performance of the regularised and tension spline interpolation techniques for predicting and mapping the phosphate concentration in the surface water of Pulau Tuba, Langkawi, Kedah. Sampling points were set up randomly along the coastal water of Pulau Tuba in November 2018. Samples were obtained using the Niskin Water Sampler at 1 meter below the surface and immediately transported into the marine technology laboratory. Phosphate levels were determined using an Ultraviolet Visible spectrophotometer and the ascorbic acid technique. The Geographic Positioning System (GPS) was used to record the geolocation of each sampling point. The training set (50%) and the testing set (50%) were chosen randomly based on 20 sampling points. The regularized and tension spline interpolation methods were used for this study. Evaluation of prediction of models was carried out using the Root Mean Square Error (RMSE) statistics. The study found that the tension spline interpolation method better predicted phosphate concentration. The Root Mean Square Error (RMSE) was reported at 0.106 and 0.094 for the regularized and tension spline interpolation methods, respectively. Concerned parties can utilize the study's findings as guidelines for monitoring, managing, and developing strategic strategies for the long-term development of the coastal waters of Pulau Tuba, Langkawi, Kedah.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
