A review on water pricing problem for sustainable water resource

2017-05-19 , Tan Kim Hek , Mohammad Fadzli Ramli , Iryanto I.

A report that presented at the World Forum II at The Hague in March 2000, said that it would be water crisis around the world and some countries will be lack of water in 2025, as a result of global studies. Inefficient using of water and considering water as free goods which means it can be used as much as we want without any lost. Thus, it causes wasteful consumption and low public awareness in using water without effort to preserve and conserve the water resources. In addition, the excessive exploitation of ground water for industrial facilities also leads to declining of available freshwater. Therefore, this paper reviews some problems arise all over the world regarding to improper and improving management, policies and methods to determine the optimum model of freshwater price in order to avoid its wasteful thus ensuring its sustainability. In this paper, we also proposed a preliminary model of water pricing represents a case of Medan, North Sumatera, Indonesia.

Connected car has become one of emerging technology in the automotive industries today. This development preludes a rise in vehicular communication studies that primarily targets radio channel modelling on vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication mode. Considering vehicular obstruction, vast channel propagation studies have focused more on V2V mode while others consider the typical urban scenarios consisting of high traffic volumes of moving vehicles. Due to challenging propagation mechanisms and high complexity in such areas, radio propagation models applied in simulators assume an obstacle-free environment rather than considering the least effect imposed by metal obstruction on communication signal. Besides, there are limited studies pertaining to metal obstruction that considers several under-explored environments such as actual parking lots, junctions and other road infrastructure support. As such, this paper demonstrates signal attenuation analysis caused by the presence of metal objects in low density over obstacle-free environment on actual parking lot via V2I mode. Two scenarios such as LOS and NLOS conditions consisting of obstacle-free, cars and buses as static metal objects are evaluated. The aim of this research is to characterize signal strength caused by metal blockage on radio wave propagation predicated on the presence of vehicles as a subject of obstruction in comparison to obstacle-free vehicular environment. The validity of data is shown through received signal strength indicator (RSSI) and approximation analysis (RMSE) to demonstrate the efficiency of obtained measurements. The results demonstrated that Log-normal shadowing model yields the best fit to low-density metal obstruction scenario with smallest RMSE of 4.78 under bus obstruction whereas 5.72 under car obstruction.

Modeling and simulation of vehicle routing problem based on clustering locations

2017-05-01 , Rosniza Mohd Nor , Mohammad Fadzli Ramli , Mohammad Huskhazrin Kharuddin

This paper aims to minimize the travelling time of vehicle routing problem that satisfies the customers’ demands and other constraints by implementing the clustering locations. Mathematical modeling represents the real problem under study and simulation of the distribution products was developed by using a simulation package in order to predict the changes. By adjusting the routes, customers demand and current location of customers, it helps to reduce the traveling and distribution time for vehicles. As a result, by implementing the clustering locations of vehicle routing problem, we predict the company will reduce the traveling time by 50% for the route 1 and 2 and 17% for route 3.

Problematic review on water tariff-pricing model and its relation with environment and climate change

2021-07-21 , Mohammad Fadzli Ramli , Hek T.K. , Hamzah Abdul Hamid , Mohd Syafarudy Abu

The issue of water security, environment degrade and climate change has becoming more severe today and emergence actions are needed to mitigate the problem. The variability in climate change affected the water resources thus contributes to unstable and uneconomic water price. This problem is worsened by environmental and pollution impact thus led to irrational water tariff and price. Existing model only considers econometric values, but environmental and climate change is neglected from overall structure of water tariff and price. Furthermore, the non-structured water pricing model fails to educate water consumers about excessive use and water scarcity. Therefore, water tariff and pricing mechanisms need to accommodate the changing in environmental degradation and climate change for more rationale and relevant water tariff and price.

Design and development of stingless beehive air pollutant monitoring system

2021-12 , Mohammad Fadzli Ramli , Azizi Harun , Rizalafande Che Ismail , Ndzi, David Lorater , Turner, Jamie Siregar Cynthia , Rohani S Mohamed Farook , Mohd Nazrin Md Isa , Sohiful Anuar Zainol Murad

Currently, the presence and levels of air pollution in most stingless bee farms are not measured periodically nor there are proper monitoring levels that can be attributed to hive productivity. Long-term measurement and monitoring of air pollution for hive productivity and honey yield have not been performed. Therefore, this research proposes long-term and real-time air pollution measurement and monitoring techniques that are important for correlation analysis and parameter modeling. By using air pollution detection sensors through a wireless sensor network topology in stingless bee farms, details of pollutant presence and levels will be available in real-time over a long period of time for hive productivity correlation analysis. With such deployment using IoT -based systems, data can be easily accessed from anywhere thus ensuring data continuity. This paper describes a preliminary study on the design, development, and testing of real-time air pollution measurement and monitoring systems capable of determining the health status of stingless bee nests in mixed livestock crop farms. The goal of this research is to help beekeepers/users maintain control and be able to take quick action on the hive from the information obtained.

This study aims to analyze the variability of defects in the production line in XX Food Industries Sdn. Bhd., using p-chart control and fishbone diagram. This company produce a food spices products whether it is well within the control or not and looking for the factors that causing to the defect products. Data collection and information obtained from interviews and documentation for the number of products and production defects for three months in XX Food Industries. The methods used to analyze products quality control by using p-chart, one of the statistical process control and fishbone diagram to determine the cause of defects products. The defects that usually occur in the production line are types of packaging defects such as leaking sachets, eyemark on the sachet sealing, and less product fill in the sachet that cause lightweight sachet. Results showed that products quality control in XX Food Industries Sdn. Bhd. is still controlled by the largest type of defects that are leaking with defects percentage 46.3 and with 36.28% percentage of defects caused by eyemark. Then, followed by defect caused by lightweight is 17.5%. Factors causing defects products are human, machine, work methods, and materials. In this case unskilled worker and the material of the plastic wrapping for the spices packet are primary cause of defects products. This study is useful in providing useful information in identifying causes for rejection or defect analysis. This research also helpful in proposing optimal solution to be implemented for productivity and quality improvement.
