Abstract
Malacca is a historical-based tourism destination. Tourism activities attract international and local tourists, together with local residents, which concentrate in Malacca Central especially near the Malacca River. Rapid development through land use and uncontrolled human activities cause contamination occur in Malacca River. Therefore, this research study has been conducted to determine public perception in water resources development. Quantitative approach applied, where questionnaire with Likert scale form are distributed for 400 respondents at Alor Gajah and Malacca Central along and adjacent to Malacca River. Meanwhile, research analysis used is chi square (x2) test with Cronbach’s Alpha is 0.759. Analysis of results showed majority respondents agreed on Malacca River is polluted due to rapid development and human activities. Pollution in the Malacca River causes poisoning, death and extinction of aquatic animals, spreads various infectious diseases, affects soil saturation and plant species, harms local residents through bad odor or acid rain and natural disaster, and destroys the natural environment overall. Hence, government, the private sector, non-governmental organizations (NGOs), and local residents should join and work together to protect the river from destruction.

Introduction
Malacca is tourism destination based on historical tourism and was recognized by UNESCO as a World Heritage Site on July 07, 2008 (UNESCO Official Portal, 2015) (Bernama Official Portal, 2008). Interestingly, Malacca is listed as one of the states that contributes highest economic value to the countries through the tourism industry (Tourism Malaysia Official Corporate Website, 2015). According to the geographical-coordinate, Malacca state is situated at N2°19’35.3” and E102°20’44.5”, referring to World Geodetic System 1984 or WGS84 (Department of Survey and Mapping Malaysia, 2009). The state is surrounded by Negeri Sembilan to the north, Pahang to the east, Johor to the south, and the sea of the Strait of Malacca to the west (Melaka State Government Official Portal, 2015). Malacca can be divided into three districts, namely Alor Gajah, Jasin, Melaka Tengah or Malacca Central, covering 1,650 km2 (Melaka State Government Official Portal, 2015). In other words, Malacca can be access using air transportation or land transportation. The total population in 2010 was 821,110 and this amount increased to 830,900 in 2011 (Melaka State Government Official Portal, 2015). In other words, the population is increased drastically especially the Malacca Central, because most of the local residents are concentrated in the district seeking job opportunities. For example, most of the interesting places to visit are located in the city or Malacca Central, and this has created more job opportunities for local residents and also residents from other states. Therefore, the city of Malacca is packed with people who come, working, and settle there for a long period of time.
Rapid development has occurred in Malacca state, bringing a lot of benefits to the local citizen. However, the development inadvertently has cause several issues and problems in the environment, such as river pollution (Nasbah, 2010). River pollution not only affects local residents carrying out daily activities like fishing, bathing, and washing, but also disturbs them in terms of bad odor, bad scenery, disease spreading, and so on (Nasbah, 2010) (Jabar, 2010) (Hua, 2014). According to a report from Department of Environment (DOE) Malaysia in 2012, 195 out of 473 rivers are considered polluted, including the Malacca River. However, the Malacca River is slightly polluted and is not yet listed as extremely polluted. So, if this issue is not taken seriously, then it will lead to a greater variety of problems to Malacca state, such as in the tourism industry. Referring to research done by Hua and Kusin (2015), there are various human activities carried out along the Malacca River, which starting from upstream river involve with agricultural and livestock activities, middle stream river involve with factories and settlement activities, and downstream river involve with commercial and settlement activities. Therefore, this research study has been conducted to determine the public perception of water resources development in Malacca River.
Methodology
Since this research study involves public perception, the method to collect the data is based on a quantitative approach, namely a questionnaire. In the questionnaire, it can be divided into two parts, namely part A (demographic profile) and part B (public perception in water resources development). The questionnaire used is in the Likert Scale form, with 5 points (1-Strongly Disagree, 2-Disagree, 3-Normal, 4-Agree, 5-Strongly Agree), akin to a ‘close-ended’ approach. In other words, the questions will provide answers for respondents to choose with no need to give any comments. The sampling area for this research study is the Malacca River, especially respondents that live along and near the river. There are only two districts involved, namely Alor Gajah and Malacca Central, because the Malacca River only spans these two district (Melaka State Government Official Portal, 2015). The sample size was set at 400 respondents (Krejcie and Morgan, 1970), which is the appropriate number for the total population in Malacca State of 830,900 (Melaka State Government Official Portal, 2015). The analysis used in this research study is chi-square (x2) analysis, and the value of reliability test (or Cronbach’s Alpha) is 0.759; this means that the items are satisfactory, suitable, and eligible for use in this analysis study.
Results and Discussions
Analysis for demographic profile and public perception in water resources development are shown in table 1, 2, and 3.

The analysis used in this research study is chi-square (x2) analysis, and the value of reliability test (or Cronbach’s Alpha) is 0.759; this means that the items are satisfactory, suitable, and eligible for use in this analysis study.
Results and Discussions
Analysis for demographic profile and public perception in water resources development are shown in table 1, 2, and 3.
Next, analysis for respondent’s perception on water resources is shown in Table-2. In the opinion of respondents, they strongly agree that water is the habitat of aquatic life (45%). However, respondents assumed that Malacca River is dirty (47.3%) due to industrial wastes that dump into river to cause river to become black color, with a smelly or bad odor, and contaminated (45.8%). When a river is polluted, it can cause disease, poisoning, and death in aquatic animals, and become a habitat to dirty animals (46.5%). Contaminated river water can cause aquatic animal’s species to extinction (42.8%). So, a majority of respondents strongly agreed that polluted water in river will affect the ecosystem (47.8%). At the same time, evaporation of polluted water from the river will cause air pollution (bad odor) (53.3%) and when raining, surface water runoff not only can cause groundwater to get contaminated (47.8%), but may also cause river water contamination to increase (49%). On the other hands, polluted water can cause the loss of soil nutrients and weaken the soil structure, which can lead to erosion and sedimentation of river basin (44.8%), and affect the plants species (41%).
According to table 3, respondent’s perception through employment on water resources development can be divided into three categories, namely variable A, variable B, and variable C. The analysis used in this part is chi-square (x2) test. In variable A, there is significant correlation (x2 = 38.501, df = 15, P < 0.05) between employment (government: 13 strongly agree; private: 38 strongly agree, self-employed: 57 strongly agree, 14 agree, 1 normal; retirees: 33 strongly agree, 8 agree, 1 normal; student: 32 strongly agree, 8 agree; others: 1 strongly agree) with factors that cause water pollution in the Malacca River. Next, variable B showed a significant correlation (x2 = 31.796, df = 15, P < 0.05) between employment (government: 14 strongly agree; private: 41 strongly agree; self-employed: 48 strongly agree, 19 agree, 1 normal; retirees: 28 strongly agree, 11 agree, 1 normal; student: 35 strongly agree, 10 agree; others: 1 strongly agree) with the impact of water pollution in the Malacca River. Lastly, variable C proved that there is a significant correlation (x2 = 35.930, df = 15, P < 0.05) between employment (government: 16 strongly agree, 9 agree; private: 45 strongly agree; self-employed: 69 strongly agree, 42 agree, 2 normal; retirees: 25 strongly agree, 9 agree, 1 normal; student: 24 strongly agree, 9 agree; others: 1 strongly agree) and impact on the environment due to water pollution in the Malacca River.
The main reason for Malacca River to be polluted is due to increasing land use area, rapid development in the urban area, and increasing of human activities without control. For example, various factories, commercial, and settlement activities are concentrated at particular urban areas which will cause the river to be polluted. When the industrial and excretory wastes are discharged into the river without treatment, this will change the water to become black, and have a bad or smelly odor, and appear dirty and polluted. These problems do not end at that point, but will lead to other issues. Where pollution exists in the Malacca River, these problems will affect the nature of water bodies through loss of oxygen in water, which in turn will affect the whole ecosystem in an environment. For example, when there is a lack of oxygen in water bodies plus with chemical wastes, this will cause aquatic animals to be poisoned and die. Once the fish are dead, this will cause other predators like snakes to die due to a limited food source. Therefore, a majority of the self-employed and retirees are in agreement, because local residents that conduct business are located near the Malacca River and are always exposed to the current situation, always watch the changing water quality and noting changes in color and lack of fish swimming in the river. Retired local residents staying for a long time in Malacca believe that the river water quality is changing to become dirty and that it is not the same as before. For example, previously local residents used river water for washing and bathing, but now there are no people that dare to approach the river due to contamination.
Next, once the water in river is polluted, it will bring with it a lot of disease, for example diarrhea, fever, infectious disease, skin disease, and so on. These problems could happen because when untreated chemical wastes from industrial are released into river, the reaction between the chemical wastes and river water will cause other dangerous solvents which encourage the growth of bacteria. This bacterium will affect the aquatic animals’ lives and cause death. If the river pollution situation worsens, then this will affect the fish species and cause extinction. This situation provides benefits as a habitat to dirty animals in Malacca River. At the same time, polluted water in river can be evaporated and exist in moisture or gas, which can lead to air pollution (example bad odor). This air pollution can mix with other gases in the clouds, which bring acid rain to the Earth surface. Since acid rain can spread in a larger area, this may increase the percentage of water pollution especially towards the Malacca River. Hence, this is the reason for self-employed respondents agreeing that they can smell a bad odor every day when running the business. In their opinion, the bad smell harms people, especially tourists that are uncomfortable to travel due to the bad odor. This situation will cause their business to decline and affect the economic status. This is followed by the majority of retirees who also agreed that when animals are dead, they bring diseases together with chemical wastes dumped by industrial businesses. So, when polluted water is exposed to hot season and it may cause evaporation process to occur, which not only brings a bad odor but also acid rain.
Lastly, when the rain falls to the Earth’s surface, the water will be absorbed into the soil to form groundwater. So, if the rain is acid rain, this will cause underground pollution which will be absorbed by plants. It definitely will cause the plants species to become wilted. Not only that, the polluted surface water from acid rain will also cause the loss of soil nutrient and weaken the soil structure once it is absorbed into the soil. Therefore, the soil structure is weakened, which may lead to erosion of river basin and sedimentation, and this can bring natural disasters like floods, landslides, and so on. Again, it is possible for the majority of self-employed and retirees respondents to agree because when raining, before the water surface runoff enters the river, it will erode the river bank and transport the sediment together entering the river which cause river to become more shallow. When this happens, all materials included in the soil erosion from the river bank will be transported and deposited in the river, leading to a decrease in the quantity of water in the river. So, these actions can lead to a nature disaster, such as a flashflood. When there is extreme raining at urban area, most of respondents with business near the Malacca River will have a little worry and concern for flashfloods because they have experience with natural disasters. Therefore, the majority of respondents are hoping that the flashflood will not happen again because this incident can bring bad experiences and trauma to local residents.
Conclusion
This research study has shown that local residents are well informed about water resources development in Malacca state, especially for the Malacca River. Most of respondents are agreed that Malacca River is polluted due to rapid development on land use and uncontrolled human activities. When the Malacca River is polluted, it will cause various problems to happen that affect aquatic animals such as poisoning, death, and possible extinction. Pollution will also affect ecosystems, spread various dangerous diseases, affect the quality of human life through bad odor and acid rain, cause groundwater to be polluted and decrease quantity of freshwater for drinking, affect plant species and weaken the soil structure through causing the loss of soil nutrient, as well as lead to natural disasters for local residents. Therefore, the government, private sector, non-governmental organizations (NGOs), and local residents should work together to protect the river from destruction and be responsible for the river, which in turn will also affect human quality of life.
