ABSTRACT

People need their home helper but do not know where to get reach to someone who has the

services. The example of services needed is plumber, lawnmower, driver, and maid. People who

have the services still promote their services like in the back days using flyers or by passing their

phone number to people. This is not systematic marketing as it only catches a few potential

customers. Here, the Home Helper Near Me System is like a platform for people who need services

(employer) and people who promote their service (worker). This will create a systematic booking

and promoting environment as it only focuses on the home services. The prices are also displayed

at the promoting page so that the employer can fix their budget, or they do not get manipulated by

the service provider. Besides, there is no middleman who will take advantage of this on both sides

because of the transparent prices range stated beforehand.

ABSTRAK

Orang yang sibuk atau orang yang tidak mempunyai kepakaran memerlukan pembantu rumah

untuk membantu mereka membersihkan dan menyelenggara rumah mereka. Contoh servis yang

mereka perlukan adalah seperti tukang paip, pemotong rumput, pemandu dan pembantu rumah.

Orang yang menyediakan servis pula masih menggunakan cara lama yang tidak efektif seperti

mengedarkan risalah atau berkongsi nombor telefon antara kenalan mereka. Hal ini sangat tidak

sistematik kerana hanya dapat menarik jumlah yang sikit pelanggan yang berpotensi. Home

Helper Near Me System adalah satu tapak untuk orang yang memerlukan servis dan orang yang

ingin mempromosikan servis. Dengan adanya tapak ini, sistem tempahan dan promosi servis akan

menjadi lebih sistematik kerana hanya fokus kepada servis berkaitan rumah. Harga juga

dipaparkan di ruangan promosi supaya orang yang memerlukan servis cakna dan boleh semak

bajet mereka dan tidak mudah ditipu oleh orang yang menyediakan servis.Tambahan pula, tiada

orang tengah yang akan mengambil keuntungan daripada kedua belah pihak kerana harga telah

dinyatakan awal dan ianya hanya berlaku di antara orang yang menyediakan servis dan

memerlukan servis.

CHAPTER 1

INTRODUCTION

1.1 Background

Poverty, forced labor, worker’s exploitation and human trafficking is happening around us.

Thus, home helpers near me work as a platform for workers to promote their services to people

who need their services. This will create an ecosystem of inclusive economic growth for the

unorganized workers. Besides, an employee or customer gets to hire and find the nearest worker

through the system. The best thing about the system is that there will be no middlemen in between

to gain the commission between the worker and customer. Customers and workers get to negotiate

the price of the services. With that, workers will have options for employment to find a better

working environment and better salaries and opportunities to improve their life. Moreover, this

platform gives advantage to those who are seeking a job as a part timer. This system is a web-

based system.

2

1.2 Problem Statement

1.2.1 Busy workers find it hard to find workers nearby.

It is not easy to find someone nearby who can help people with their housework. People

are working and need to fix their house problem, but they do not know where to find nearby

workers available. House helpers are different from maids as they do not live or are tried to

working with certain customers. Workers are free to accept any job that customers offer to them.

1.2.2 Employers are not aware of nearby workers.

In every neighborhood, there must be workers who provide their service but not all people

know about it. Some of the workers are still using old methods to promote their services such as

by using flyers or posters. People mostly are not aware of this kind of advertisement as the

technology is already taking over the old method. Promotion through WhatsApp application is still

not enough to make all the neighborhood aware of the service.

3

1.2.3 Middlemen who take opportunity through commission.

When working through middlemen such as agents, workers might be manipulated, and

their salary is not equal to their service. This is because middlemen tend to take opportunities to

take commissions from the worker’s service. Most of the time, customers are not aware who their

house helper is when using agents as middlemen. This can cause unsatisfying service. Customers

also tend to lose an amount of money for an unsatisfying service.

1.2.4 Workers lacking in knowledge to promote their services broadly.

Nowadays, everything involves technology as we are entering the 4.0 industry revolution.

People are using social media and other types of advertisement platforms to promote their product

or service. Not all people have the expertise. For workers who have no expertise in the field might

find it hard to get the job. They might still be using the old way to promote their service and it's

hard to reach their customers.

4

1.3 Objectives

1.3.1 To develop a platform for employers and customers to find a job and find those who serve

services without middlemen in between.

1.3.2 To design a process flow, structure of user interface and database from Home Helper

Near Me System

1.3.3 To test the capabilities of the Home Helper Near Me System and generate a report to the

user.

1.5 Implementing and Planning

Gantt chart is used to describe activities and timescale that involves in implementing this project

as shown in Table 1.1.

Table 1: Gantt Chart

1.6 Limitations

This system involves admin, customer, and worker. Only the admin can view, report and

manage the system. Customers as a user only can view workers near them, contact the worker and

book their service. Customers need to log in or register to the system before proceeding in booking

the services. Workers can update their services, expected salaries, and receive messages from

employers.

8

1.7 Expected result

The expected results of the project are facilitating each party- CUSTOMER, ADMIN and

WORKERS in the Home Helper Near Me system can manage booking services, manage user

accounts, and manage update accounts.

1.8 Organizations of the Thesis

The thesis is organized in six chapters, including the introductory chapter which discusses

the background, problem statement, objectives, scopes, implementing and planning, limitation and

expected results. The remaining of the chapters is as follows:

Chapter 2 discusses literature review. This system is being studied by comparing the existing

application, to identify the advantages and improve the disadvantages and implement in this

system.

Chapter 3 describes the methodology process involved in this system. The chapter discusses what

method of sdlc is being applied to the system, how the system design and modelling, the entity

relationship diagram, and data dictionary of the Home Helper Near Me system.

Chapter 4 will discuss overall about the system including interface and its function. This chapter

also discusses the testing and result from the system. Testing is conducted to test the functionality

of each of the modules in the system. This chapter will verify the home helper near me system

correctly developed and meet their requirement specification. The interface of this system uses the

template from Bootstrap, but the developer needs to edit the coding to make sure the interface

follows the user requirement.

Chapter 5 will discuss project contribution, project constraints, and recommendations that can be

taken to improve the functionality of the system in the future.

2.3 Global Positioning System (GPS)

GPS positioning is based on trilateration, which is the method of determining position by

measuring distances to points at known coordinates. At a minimum, trilateration requires 3 ranges

to 3 known points. GPS point positioning, on the other hand, requires 4 “pseudoranges” to 4

satellites. This raises two questions which are what are pseudoranges and how do we know the

position of the satellites?

Pseudoranges is the time that the signal is transmitted from the satellite is encoded on the

signal, using the time according to an atomic clock onboard the satellite. Time of signal reception

is recorded by the receiver using an atomic clock. A receiver measures difference in these times:

Pseudorange = (time difference) × (speed of light)

We know the position of the satellites with a signal is transmitted from each satellite in

the direction of the Earth. This signal is encoded with the Navigation Message, which can be read

by the user’s GPS receivers. The Navigation Message includes orbit parameters (often called the

“broadcast ephemeris”), from which the receiver can determine satellite coordinates (X,Y,Z).

These are Cartesian coordinates in a geocentric system, known as WGS-84, which has its origin

at the Earth's center of mass, Z axis pointing towards the North Pole, X pointing towards the Prime

Meridian (which crosses Greenwich), and Y at right angles to X and Z to form

15

a right-handed orthogonal coordinate system. Ephemeris Algorithm is an algorithm which

transforms the orbit parameters into WGS-84 satellite coordinates at any specified time.

Some GPS receivers also calculate accumulated delta-ranges (ADR) which keep track of

the distance changes between the user and the satellites. They are much more precise than code-

based pseudoranges, but in contrast to them they have ambiguous starting value and cannot be

used for standalone positioning. ADRs are usually used for smoothing pseudoranges, in

differential GPS or for attitude determination. These methods and applications, however, are out

of the scope of this paper and therefore AD observables are not considered here. Both

pseudoranges and delta-ranges contain significant components connected with the clock errors,

due to the lack of synchronism of a relatively low-quality GPS receiver clock with high-accuracy

clocks installed in satellites. These components represent additional variables of bias and drift

which must be estimated along with the user’s position and velocity. Fortunately, the receiver

clock bias is common to all the observed pseudoranges and the clock drift is common to all the

observed delta-ranges. Therefore, their estimation is relatively simple.

The pseudoranges and delta-ranges from the user to the i-th GPS satellite are non-linearly related

to the user’s position and velocity by the following equations;

ρᵢ -pseudorange between the user and the i-th satellite,

ṗi -delta-range between the user and the i-th satellite,

16

rᵢ = [ Xᵢ Yᵢ Zᵢ]ᵀ -position of the i-th satellite,

rᵤ = [ 𝓍 𝑦 𝓏]ᵀ -user’s position,

vᵢ = [ V𝓍i V𝑦i V𝓏i]ᵀ -velocity of the i-th satellite,

vᵤ = [ V𝓍 V𝑦 V 𝓏]ᵀ -user’s velocity,

b -bias in the GPS receiver clock scaled in distance units [m],

d -drift in the GPS receiver clock scaled in velocity units[m/s],

εpi -pseudorange measurement error,

εṗi -delta-range measurement error

It is necessary to solve a set of the above equations to calculate the position and velocity of the

user, formulated for several visible and tracked GPS satellites. The GPS positioning is realised in

the Cartesian ECEF (WGS-84) coordinate frame . There exist numerous concepts of PVT

estimation, which can be divided into single-point solutions and kinematic solutions algorithms.

• Single-point PVT Estimations Methods

The simplest methods of PVT calculation are single-point solutions algorithms, processing

only pseudoranges. They include ordinary-least-squares (OLS) and weighted-least-squares (WLS)

methods which iteratively estimate the user’s position and receiver clock bias.

• Kinematic PVT Estimation Methods

Single-point methods do not use information from previous steps of data processing, as for any

new portion of observables, a new PVT solution is calculated. Going a step further, it is possible

17

to model the user’s motion and use this model for prediction of position and velocity as well as

clock errors at the next era, based on the navigation solution from the previous epoch. This way,

information from historical measurements is preserved in new solutions and the estimated data are

less subject to rapid changes of satellite geometry or accuracy of measurements. The new

observables in this concept are used for correction of the previous solution, thus even if less than

four GPS satellites are tracked, the new estimates can still be obtained. In such a case, the matrix

H in OLS or WLS would become rank-deficient and no solution would be calculated. There exist

models of motion applicable to diverse types of users (platforms or vehicles). They can be divided

into two groups, i.e. dynamics models and kinematics models. Properly formulated dynamics

models are more accurate than the kinematics but they are expressed by a set of complicated

nonlinear differential equations and require good knowledge of the platform’s size, weight,

geometry and parameters of environment (e.g. air density, temperature ,etc.). Thus, they are

cumbersome in use, especially in GPS receivers, which can be fitted to any type of platform. The

kinematics models are simpler and more universal. For this reason, they are better suited for use

in GPS receivers. The kinematics models are based on first-order, linear differential equations,

expressing relationships between the user’s position, velocity, acceleration and so on. Such models

are driven by Gaussian white noises, representing uncertainties in the model and connected with

unknown navigate forces (unknown actions of the driver/pilot/operator) as well as unknown

influences of the environment, e.g. random gusts of wind etc. Typical models used for this purpose

are models: P (like Position), PV (like Position/Velocity) and PVA (like Position/

Velocity/Acceleration). They contain different numbers of state variables and are suitable for

platforms of different level of maneuverability. The best suited model is the P model for almost

18

stationary or very slowly and randomly moving platforms, such as sea buoys, tethered balloons,

etc., which assumes that the position changes are caused by random disturbances,

physically caused by waves, wind gusts etc. Such a model is given as follows:

Where;

ṙᵤ - the user’s position

u - represents random velocity, modelled as a vector of zero-mean Gaussian white noises.

2.4 Conclusion

This chapter reviewed the comparison of the existing applications. The technique used in

this system is Global Positioning System (GPS) Technique. This includes two methods which are

single-point PVT estimation methods and kinematic PVT estimation method.

CHAPTER 3

METHODOLOGIES

3.1 Introduction

Project methodology is the systematic, theoretical analysis of the methods applied and

encompasses concepts such as paradigm, theoretical model, phases and quantitative or qualitative

techniques. While software development methodology is often considered as a subset of Software

Development Life Cycle (SDLC). Which splitting the work into the phases of activity for better

planning and management for home helper near me development.

20

3.2 Methodologies

Software development life cycle (SDLC) is a framework that defines the steps involved in

the development of software at each phase. It covers the detailed plan for building, deploying, and

maintaining the software. There are few types of model in the Software Development Life Cycle

(SDLC). Home Helpers Near me are more suitable on spiral models. This model starts with the

planning phase and ends with the evaluation phase.

3.2.1 SDLC phases are:

Requirement gathering

Requirement analysis is the most important and fundamental stage in SDLC. It is

performed by the senior members of the team with inputs from the customer, the sales department,

market surveys and domain experts in the industry. This information is then used to plan the basic

project approach and to conduct product feasibility study in the economical, operational and

technical areas.

Planning

Planning for the quality assurance requirements and identification of the risks associated

with the project is also done in the planning stage. The outcome of the technical feasibility study

is to define the various technical approaches that can be followed to implement the project

successfully with minimum risks.

21

Design

In this phase, the requirements gathered in the SRS document are used as an input and

software architecture that is used for implementing system development is derived.

Implementation

Implementation/Coding starts once the developer gets the Design document. The Software

design is translated into source code. All the components of the software are implemented in this

phase.

Testing

Testing starts once the coding is complete and the modules are released for testing. In this

phase, the developed software is tested thoroughly, and any defects found are assigned to

developers to get them fixed.

Retesting, regression testing is done until the point at which the software is as per the

customer’s expectation. Testers refer to SRS document to make sure that the software is as per the

customer’s standard.

22

Figure 1: Spiral model

3.2.2 Spiral model phases are:

Planning phase

Problem was identified that the needs of home helpers are crucial in residential areas where it is

hard to find a trusted helper to help them. In the planning phase, the requirements are studied and

gathered to proceed to the next phase without complication.

Risk Analysis Phase

In this phase, requirements of the home helper near me system are studied, and brainstorming

sessions are done to identify the potential risks. Once the risks are identified , risk mitigation

strategy is planned and finalized. The output of this phase would be in a document which highlights

all the risks and its mitigation plans.

23

Developing and Testing Phase

In the developing and testing phase, actual development, and testing if the software takes

place. It includes testing, coding, and deploying systems at customer sites.

Evaluation Phase

Customers evaluate the home helper near me system and provide their feedback and

approval in this phase. Also, it includes identifying and monitoring risks such as schedule slippage

and cost overrun.

3.4 System Design and Modelling

System design and modelling is a systematic approach that is required for a coherent and

well-running system. Bottom-Up or Top-Down approach is required to take into account all related

variables of the system. A designer uses the modelling languages to express the information and

knowledge in a structure of system that is defined by a consistent set of rules and definitions. The

designs can be defined in graphical or textual modelling languages. Some of the examples of

graphical modelling languages are context diagram, entity relationship diagram and data

dictionary.

26

3.4.1 Framework Design

Figure 2 below shows the flow of how the admin, workers, and employers used the system.

The system must host on a web server, which will be configured to compile on command. It will

contain a database, which stores all data, which will be accessible by the user. To access the

system, all users need a web browser. Users need to login into the system to enable them to manage

it.

Figure 2: Framework Design

27

3.4.2 Context Diagram

A context diagram or a level 0 data-flow diagram, is drawn in order to define and clarify

the boundaries of the software system. It identifies the flows of information between the system

and external entities. The entire software system is shown as a single process. The context diagram

for the home helper near me system is shown in Figure 3 below.

Figure 3: Context Diagram

28

3.5 Data Flow Diagram

3.5.1 Data Flow Diagram (DFD) Level 1

A data flow diagram (or DFD) is a graphical representation of the flow of data through an

information system. It shows how information is input to and output from the system, information

sources and destinations, and where it's stored. Home helper near me system used three entities

which are admin, employers, and workers. There are nine total processes which are managed

accounts, view worker nearby, deals, rating, contact, service, agreement, and report. The admin

has one major process which is managing accounts. The employer has five major processes which

are view worker nearby, deals, rating, contact and report while the workers has four major

processes which are contact, service, agreement, and report. The data flow diagram is shown in

Figure 4 below.

Figure 5 below shows the level 1 Data Flow Diagram for process 3.0 which is dealt.

Employers need to enter the location, service, and date. Then, they can view the available worker

by the location, service and date to proceed for booking. Employers also can make cancellation by

inserting the booking id.

31

3.6 Entities Relationship Diagram (ERD)

An entity relationship diagram (ERD) shows the relationships of entity sets stored in a

database. These entities can have attributes that define its properties. By defining the entities, their

attributes, and showing the relationships between them, an ER diagram illustrates the logical

structure of databases.

3.7 Data Dictionary

A data dictionary contains metadata for example data about the database. The data

dictionary is especially important as it contains information such as what is in the database, who

is allowed to access it, where is the database physically stored etc. The users of the database

normally don't interact with the data dictionary, it is only handled by the database administrators.

CHAPTER 4

IMPLEMENTATION AND RESULT

4.1 Introduction

This chapter will discuss overall about the system including interface and its function. This

chapter also discusses the testing and result from the system. Testing is conducted to test the

functionality of each of the modules in the system. This chapter will verify the housemaid selection

system correctly developed and meet their requirement specification. The interface of this system

uses the template from Bootstrap, but the developer needs to edit the coding to make sure the

interface follows the user requirement.

37

4.2 Implementation of Home Helper Near Me

Home Helper Near Me is developed using several languages. For the interface, Html website

template and SB Admin have been used. For the programming language, this system used PHP

(Hypertext Preprocessor) language. PHP is widely used because it is an open source for general-

purpose scripting language, can be embedded into HTML and it suits for Web development. This

system used HTML5, PHP and JavaScript for the validation. Validation is important to make sure

users have a minimum chance to make mistakes when inserting data. Open Source database is also

used in this system and the database is 43 MySQL version 5.6.26 - MySQL Community Server

(GPL). Apache used to run local host servers and the apache version is 2.4.16. Visual studio used

for writing and editing the code.
