Abstract
Solid waste management of the country had been revived through the enforcement of Solid Waste Management
and Public Cleansing Act 2007 (Act 672) started from 1st of September last year. The duty to manage the waste
was transferred to Federal Government. According to the act, the research had been carried out to study the
effectiveness of Municipal Solid Waste management by related parties at residential and commercial area in Batu
Pahat through feedback from public and workers. Collection of data was conducted through distribution of survey
forms, interview sessions, sampling and observation made during waste collection. Gathered data were analyzed
by using statistical software like Microsoft Excel and SPSS (Statistical Package for Social Sciences). Pilot Test,
Reliability Test, Average Index and Level of Agreement were used in data analysis. Study showed public
respondents agreed with waste collection system of study area with value of 𝑥̅ = 3.65. They also agreed with
current issues of waste management with value of 𝑥̅ = 3.84. Whereas 71% of respondents confessed never making
complaint regarding waste collection. Respondents from concession company agreed with waste collection work
procedures with value of 𝑥̅ = 3.80. There were 63% of respondents admitted the frequency level of leachate spill
was sometimes. In conclusion, the effectiveness of the Municipal Solid Waste management in the study area was
satisfactory. Further study can be carried out by considering additional assessment tools such as time motion study
and analysis of solid waste collection routes to get more comprehensive results.

Introduction

Before the existence of the Solid Waste and Public Cleansing Management Act 2007 (Act 672),
solid waste management is a common practice being responsible to Local Authority (LA) in Malaysia
since long ago. However, a fairly well-planned management was started in 1976 through the provisions
of the Local Government Act 1976. It should be understood that according to the existing law at the
time, local authorities only manage solid waste in their administrative areas such as business premises
and houses whereas solid waste management outside of LA’s operation area such as villages in rural
areas was coordinated by the Ministry of Health Malaysia [1].
On average, every Malaysian produces 0.8 kg of waste per day. This amount gets larger if we
take into consideration the people living in the urban. People living this area are estimated to produce
1.5 kg of waste per day. According to statistics released by the Ministry of Housing and Local
Government in 2001, 16,247 tonness of garbage produced daily in Malaysia. Selangor was ahead of
other states with production of 2,955 tonnes of garbage per day. This was followed by Kuala Lumpur
(2,634 tonnes/day), Johor (2,002 tonnes/day), Perak (1,596 tonnes/day) and Kedah (1,383 tonnes/day)
[2]. These statistics show the need for new landfills is becoming critical, while the rate of solid waste
generation is increasing, in line with the increase of population as estimated in Table 1 [3].

Quantity of solid waste generated by the developed countries is greater than the developing
countries. Municipal Solid Waste (MSW) for most of the developed countries, such as Japan, composed
of less organic material compared to other developing countries [4]. MSW production trends per capita
for developed countries like Japan is 1.2 kg per person per day. While developing countries like Nigeria
is 0.55 to 0.58 kg per capita. Japan adopted incineration system as the main method for managing MSW
as well as 3R method (Reduce, Reuse, and Recycle). For developing countries, they used landfill and
open dump site to the dispose MSW with a cheaper cost or no cost at all, compared to the developed
countries. According to the Southern Waste Management (SWM), which is a private company
appointed to manage MSW in Southern Peninsular Malaysia, in a Civil Engineering seminar titled
‘Environmental Preservation Through Recycling,’ on average, each person produces 0.8-1.0 kg of waste
per day and Malaysian generate 18,000 tons of waste per day or 0.6 kg per capita [5].

Literature Review

2.1

Definition of Solid Waste

The term ‘solid waste’ includes material considered worthless to be used and usually discarded
as garbage by the community [3]. Based on the Solid Waste Management and Public Cleansing Act
2007 (Act 672) [6], ‘solid waste’ includes:i)

Any scrap or surplus materials that are not required or rejected products arising from the use
of any process.

ii)

Anything that is required to be disposed due to it is broken, worn out, contaminated or
otherwise damaged.

iii) Any other material under this act or any other written law might required by the authority
for disposal.

2.2

Classification of Solid Waste

The Solid Waste Management and Public Cleansing Act 2007 (Act 672) [6], classified controlled
solid waste is divided into 8 types as shown in Figure 1.

2.2.1 Municipal Solid Waste
Municipal Solid Waste (MSW) contains a useless waste to anyone as well as to the owner of the
material. But the waste may be used or recycled for more useful purpose. The term 'solid' indicates that
the MSW does not have sufficient liquid content to allow it to flow freely (free-flowing). While the
term 'urban' shows MSW is collected in urban areas such as cities, small towns by town council (LA)
or private cleaning company [7].

Figure 1: Eight types of controlled solid waste according to Act 672

2.2.2 Residential Solid Waste
According to the Solid Waste Management and Public Cleansing Act 2007 (Act 672),
'Household Solid Waste' that contains any solid waste generated by a household and of a kind that is
normally produced by or disposed by any premises when occupied as a dwelling house and included
garden waste.

2.2.3 Public Solid Waste
Act 672 stated that public solid waste as any solid waste generated by the public place, which is
under the supervision or control of any local authority. Examples of public solid waste is rubbish along
the streets under the maintenance of the Local Authority (LA), landscape waste, playgrounds, beaches
and other recreational areas.

2.3

Sources of Solid Waste Generation

Solid waste generated from the residential, commercial, industrial, institutional, construction,
treatment plants and municipal services. This research is focused on residential and commercial areas
in which both areas are places for major human activities with variety of organic and inorganic waste
that are non-flammable. Organic waste from residential and commercial premises contain substances
that are susceptible to rotting and sometimes smelling. Organic waste consists of materials such as food
waste, various types of paper, plastic, kadbord, textiles, rubber, yard waste (garden/orchard), wood and
products of animal skin. Inorganic material consists of glass, tin, aluminum, cooking utensils, materials
containing iron and ash [8].

2.4

Solid Waste Management

Solid waste management system should be systematically planned and implemented as
population growth and people's lives becoming more advanced. This is due to solid waste disposal rate
depends on population growth as well as quality of life and economy. The increasing amount of solid
waste should be managed so that the impact of management failures do not occur. For implementation
system, a well-planned, organized, efficient, effective and high-tech management are necessary to
ensure well-being of human life and animals as well as the environment present in the earth.

2.5

Storage of Solid Waste

Solid waste produced will be collected and gathered in areas where it will be collected and taken
to a disposal site. Therefore, the waste should be stored while waiting for the process of collection and
disposal of solid waste in other area being completed. Factors to be considered in the process of storage
are [8]: i)

Type of containers

ii)

Location of containers

iii)

Effect of storage on waste content

iv)

Health and aesthetic aspects

2.5.1 Type of Containers
There are various types of container used in throughout the country. Some of these are as follows:

2.6

Solid Waste Collection

Solid waste collection activity is the process of collecting solid waste and take it to storage or
disposal site. Collection is the most important element and it is estimated that almost 80 percent of the
total solid waste management costs incurred for the work of collection of solid waste [9]. Therefore, the
relevant method should be reviewed based on the application and suitability, as well as frequency of
collection and the vehicle used in order to produce a solid waste collection system that effectively and
in accordance with the current situation. Solid waste collection system depends on the location of the
generation, quantity, source and type of waste produced.

2.7

Collection Method

Collection methods affect the quality and quantity of resource recovery and waste disposal
system. There are 4 methods of collection: i)
ii)

Block collection

iii)

Street collection

iv)

2.8

Collection of accumulated storage

House-to-house collection

Solid Waste Management in Malaysia (Legislation and Development)

In 1996, solid waste management in Malaysia was privatized. Although local governments have
lot of manpower and equipment, financial difficulties becoming the challenge to improve quality of
solid waste management. Under the privatization program, the four consortiums have been appointed
and divided into their respective zones, one of them was SWM Environment Sdn. Bhd. assigned to
Johor, Negeri Sembilan and Melaka.
However, the privatization policy has not shown positive results due to the solid waste
management system in Malaysia still inefficient and imperfect. Thus, on August 30, 2007, the Solid
Waste and Public Cleansing Act 2007 was enacted with a focus on management responsibility to the
Federal Government and the privatization of solid waste handling. The Act came into effect on 1st
September 2011. Hence, the role of enforcement of solid waste management was transferred to
Perbadanan Pengurusan Sisa Pepejal dan Pembersihan Awam (PPSPPA) in each state. Besides,
amendments were made to the three policies, namely the Local Government Act 1976, ‘Site, drainage
and Building Act 1974’ and ‘Town and Country Planning Act 1976’ [3].

Methodology

3.1

Methods of Data Collection

3.1.1 Method of Sampling
Public (respondents) involved in this study consists of three group of residents living in selected
neighborhoods of Taman Universiti, Pura Kencana and Evergreen Heights. According to Mr. Izwan
Mohd Amin, Enforcer Assistant of PPSPPA Batu Pahat branch, the number of houses that available in
the three study areas are 1945 units. While the number of shophouses (commercial) are 503 units. Table
2 shows the breakdown of the number of houses and shophouses according to residential area studied.
Thus, in order to get thorough distribution of questionnaires in this study, a total of 80 samples were
selected from three residential areas with the percentage was determined by the total number premises
available in the area. Of the total, 60 respondents were housing residents while 20 respondents are
shophouse owners. Allocation of the number of samples is specified in Table 2 below.

Meanwhile, for sampling of the workers, respondents involved in the study were selected among
the cleaning concession company workers which is SWM Environment Sdn. Bhd. and its subcontractors, A. Rahman Enterprise. Number of workers (garbage collection) of SWM Environment
Batu Pahat branch was 99, while A. Rahman Enterprise was 28 person. Table 3 shows breakdown of
the number of workers of both companies based on routing and tasks. Thus, a total of 40 sets of
questionnaires were distributed equally among the workers of two companies.

3.1.2 Method of Questionnaires
Questionnaire for public respondents is conducted by visits from house to house and from one
shop to another. Another set of questionnaires are distributed among workers from both companies. The
questionnaire designed for public consists of 3 sections, namely Part A) Demographic, Part B) Feedback
on MSW collection system and Part C) Feedback on current issues of MSW management. Questionnaire
for the workers consist of 2 parts, namely Part A) Demographic and Part B) Feedback on MSW working
procedures. 5-points Likert scale are used to assess the level of agreement for each variable presented
in the questionnaire. Score 1 represents "strongly disagree, SD,' score 2 represents ‘disagree, D,' score
3 represents ‘not sure, NS,’ score 4 represents ‘agree, A' and score 5 represents ‘strongly agree, SA'.

3.2

Pre-analysis of Data

Survey instrument (questionnaire) must be verified its validity and reliability as the initial
formation of questionnaires before it can be really used by all respondents. This steps include the Pilot
Study and Reliability Test for the public and worker questionnaires. Statistical software like IBM®
SPSS® Statistics version 21 is used to run the test.

3.2.1 Pilot Study
Pilot study is a small-scale preliminary test conducted before a major study (the real test). It is
intended to check the feasibility or to improve the design of research instruments (questionnaire). It is
carried out to determine the effectiveness and adequacy of sampling. Ten samples are selected for each
group of questionnaire (the public and workers).

3.2.2 Reliability Test
Reliability Test shows the degree of consistency of the data collected. Coefficient of Cronbach
Alpha (α) is a measure of internal consistency. Reliability of an instrument (questionnaire) is low when
α value less than 0.3 and it is not acceptable. Reliability is high when the value of α greater than 0.7,
indicates internal consistency of the index table is high and it is highly acceptable. However, [10] argued

that the value of α between 0.3 and 0.7 is still can be accepted. They also stated that there is a common
agreement that the data is still acceptable if the value of Cronbach α reaches 0.6.

3.3

Data Analysis

The type of data analyzed in this study involved only quantitative data (multiple response and
Likert scale questions). With the aid of statistical analysis software such as Microsoft® Excel 2013 and
IBM® SPSS® Statistics version 21, data analysis can be done and presented in the form of graphical
analysis as well as descriptive like pie and bar charts.

3.3.1 Average Index, ̅
𝒙
Average Index is identified as a tool for determining the level of agreement for each feedback on
waste collection system, current issues of waste management and waste collection working procedure
in order to contribute to effectiveness of Municipal Solid Waste (MSW) management. The data obtained
from the Likert scale were analyzed by using the 'Average Index' method [11]. Value of Average index
for each variable (question/factor) is calculated using the following formula:

Average Index =

∑ 1(𝑥1 ) + 2(𝑥2 ) + 3(𝑥3 ) + 4(𝑥4 ) + 5(𝑥5 )

(1.0)

𝑥1 + 𝑥2 + 𝑥3 + 𝑥4 + 𝑥5

Where, 𝑥1 = Number of respondents for scoring ‘strongly disagree, SD’
𝑥2 = Number of respondents for scoring ‘disagree, D’
𝑥3 = Number of respondents for scoring ‘not sure, NS’
𝑥4 = Number of respondents for scoring ‘agree, A’
𝑥5 = Number of respondents for scoring ‘strongly agree, SA’

3.3.2 Level of agreement
Level of agreement is a measurement for interpreting the average response obtained from the
questions in the questionnaire. It is in the range of Likert scale 1- 5. It can also be used as a generalization
of the opinion for a group of respondents represents studied area. This method can give clues to the
level of agreement on the matters set in each of the questionnaire [12].
Evaluation table as shown in Table 4 is used for assessing the level of agreement for each
question/factor that has been calculated its average index value [13].

Data Analysis and Results

4.1

Analysis of Questionnaires from the Public

Figure 3 shows a total of 60 respondents (75%) are the people living in residential area, while
20 respondents (25%) are occupants of commercial premises in the housing area. Out of 60 respondents
who occupied residential units, 12 (15%) are from Taman Universiti, 13 (16:25%) from Pura Kencana
and 35 (43.75%) from Evergreen Heights. Number of respondents from commercial premises at Taman
Universiti are 11 (13.75%), followed by Pura Kencana, 4 (5%) and Evergreen Heights, 5 respondents
(6.25%).

Figure 3: Distribution of respondents according to the type
of premises in the three residential area
Feedback on waste collection system shows that respondents agree with all the factors that
contribute to the effectiveness of waste collection by the average value, 𝑥̅ = 3.65. They agreed that the
collection is done quickly and smoothly and the frequency of collection is satisfactory. But the residents
still not aware about the function of PPSPPA as a monitoring board for solid waste collection operations
in their neighborhoods.
Figure 4 shows the highest number of respondents (32 people) are those who argue that the
frequency of waste collection failure is rarely happened. There are 4 respondents that argue frequency
of failure of solid waste collection is very often, whereas those who are not sure about this are 5
respondents.

Figure 4: The frequency of failure of solid waste collection in the study area

Feedback on current issues of waste management shows that respondents agreed with all the
issues that contribute to the effectiveness of waste collection by the average value, 𝑥̅ = 3.84. The issue
they most agree with is 'waste not collected will produce bad odor and affect the surrounding view.’
This result also consistent with the study [5], that proved the frequent problems complained by public
are smelling, waste being scattered all around the place and clogged drainage systems, all of these
problems really affect the view.
Figure 5 shows the majority of respondents (57 people) claimed that they never make a complaint
regarding waste collection. The rest of them, (23 respondents) ever had a complaint, with the highest
number of respondents are 11, chose to make a complaint to the local authority, while complaints to the
concession company, others and PPSPPA are 7, 4 and 1 respectively. These statistics prove there are
no serious problems regarding waste collection within the studied area. But they should aware of the
proper channel to make complaints at the present time is PPSPPA.

Analysis of the Questionnaires from the Workers

Figure 6 shows the highest number of respondents comprised of workers from SWM
Environment Sdn. Bhd which is 20 respondents (57.1%), while the number of respondents from the A.
Rahman Enterprise is 15 respondents (42.9%). The distribution number of respondents based on the
collection scheme area in the study as shown in Figure 7, with a total of 20 respondents (57.1%)
assigned for waste collection at Evergreen Heights, 9 respondents (25.7%) at Taman Universiti and
lastly, 6 respondents (17.1%) at Pura Kencana.

Feedback on work procedures of waste collection shows that respondents agreed with all the
procedures that contribute to the effectiveness of waste collection by the average value, 𝑥̅ = 3.80. The
work procedure they most agree with is collection is being made just for correct waste types and at
approved premises only. They also agree the workers manage to avoid garbage leachate spills from
happening. This is due to the spills are serious matter concerned by the public. Daily Express on October
18, 2012 reported there was a complaint from the public regarding the effects of leachate spills left
behind shops in Damai, Kota Kinabalu. Collection workers were warned not to repeat such things by
municipality [14].
Figure 8 shows the majority of respondents, 22 (62.9%) admitted the leachate spills were
'sometimes' happened, 6 respondents (17.1%) claimed it was 'often/always' and 'rarely' respectively.
None of the respondents claimed the spill 'never' happened. Lastly, only 1 respondent (2.9%) said ‘not
sure/do not know’ about the spills frequency. These results indicate there is still room for improvement
in this solid waste collection service.

Conclusion

The first objective is to study the effectiveness of the Municipal Solid Waste (MSW) management
is achieved through the response of questionnaire from the public. Most of respondents who live in the
house and shop premises (commercial) give positive feedback towards the collection system. They
agreed and satisfied with waste collection system available.
The second objective of this study, which is to assess the level of competency of workers in
performing MSW collection is achieved through questionnaire from the workers. Most of the
respondents from the two companies give positive feedback to work procedures stated in questionnaire.
They agreed with the work procedures that contribute to the effectiveness of waste collection.
The third objective is to identify and evaluate the effectiveness of MSW collection method. It is
achieved through observation, surveys and interviews conducted towards PPSPPA, MPBP, SWM
Environment and A. Rahman Enterprise throughout the study. Solid waste collection methods in the
study area are from house to house (also from shophouse to another shophouse) and it make use of
compactor truck. Its effectiveness is satisfactory and on schedule.
In conclusion, the effectiveness of solid waste management in the study area is contributed by
the various parties such as concession/ contrator, PPSPPA enforcer and the resident themselves, hence
it is satisfactory enough.
