Abstract—Application of web-based raw material inventory 

control information system with a bill of materials (BOM) 

using the PHP and MySQL programming language as a 

database, and using the SDLC livestock device engineering 

method with stages of planning, design, implementation, and 

testing. I create a recording application that provides 

information about the availability of raw material reducing the 

error in calculating the amount of raw material based on the 

bill of material. With this application, it can help to purchase 

in determining the number of raw materials needed for 

production based on the master bill of material data. 

Keywords— Inventory, bill of material, information system. 

I. INTRODUCTION 

This The production process is the core activity of a 
manufacturing company. In the production process, they 
require a company to produce a quality product following 
consumer desires. To conduct production activities, good 
raw materials must be available and following the company's 
production needs. Therefore, determining the raw material 
inventory and is a very important activity in a production 
process. 

Planning for the right raw material inventory is very 
supportive in the smooth production process. The smooth 
production process is very important for the company 
because it is very influential on the level of sales and profits 
got by the company. Factors that influence the smooth 
production process are the availability of raw materials that 
will be processed in the production process. 

If raw material inventory is not available with the 
required amount or raw material is late until the company, 
then it will have a bad influence on the company that is 
affecting the company's profits, this is because of costs 
incurred for the company running out of inventory which 
results in lost opportunities benefit because consumer 
demand cannot be served and the production process is 
interrupted. 

In the research the author will conduct that is research on 
controlling raw materials in electronic products in the SIIX 
EMS (Electronic Manufacturing Services) company. The 
main raw materials for the electronic products are PCB 
(printed circuit board), capacitors, resistors, LEDs (Liquid 
Crystal Display) and diodes. Description of raw material into 
finished goods presented by PT. SIPX Ems Indonesia in the 
form of (BOM) bill of materials is a special table that shows 

how raw material changes into finished products. In the bill 
of material will show each product has a composition of any 
raw material and the size or amount needed to make one 
finished product. 

With the problems that occur in controlling the residual 
and the need for the use of raw material production, the 
author intends to analyze the system design Information 
System Inventory Control Material Production Row in P.T. 
SIIX EMS Indonesia. 

II. THEORETICAL BASIS 

A. Information Systems 

In the research process information system design 
requires an understanding of information systems, there are 
several opinions according to experts as follows: 

Information Systems are systems that can be defined by 
collecting, processing, storing, analyzing, distributing, 
information for specific purposes. Like other systems, an 
information system consists of inputs (data, instructions) and 
outputs (reports, calculations) " [3]. 

Information Systems is a system within an organization 
that meets the needs of daily transactions that support the 
organization's operational functions that are managerial with 
the strategic activities of an organization to be able to 
provide certain external parties with the reports needed "[4]. 

In simple information systems of understanding above 
have in common that the information system will produce a 
report, meaning a process that produces a report or data. 

B. System Analysis 

In a study a researcher must find the existing problems 
and solve those problems with certain methods of the system 
running and aims to find out all the problems that occur and 
facilitate in carrying out the next stage through analysis that 
has been made, according to experts the analysis of the 
system can be defined as the following: 

Argues that system analysis is a process of reviewing an 
information system and dividing it into its constituent 
components for later research so that known problems and 
needs that will arise so that it can be reported in full and 
proposed improvements to the system " [5]. 

 Analysis of the system is a method for finding solutions 
to existing system problems by grouping existing

Buana Information Tchnology and Computer Sciences (BIT and CS) 

components into smaller components so that the solutions 
found by system requirements [6]. 

From the above definition, quotations have in common in 
the understanding that analysis is the process of solving the 
problem means that the existing problems will be solved by a 
particular method to get a solution to the problem. 

C. Waterfall 

Someone who conducts research certainly has a method 
of solving problems in a study, one of which is the waterfall 
method of various methods that will also be used by the 
author. This method is a classic method but is still often used 
in research methods, experts are precise about this method as 
follows: 

Waterfall is one method of developing information 
systems that are systematic and sequential, meaning that each 
stage in this method is carried out sequentially and 
continuously [7]. 

The waterfall model as one of the basic theories and as 
required to be studied in the context of the software life 
cycle, is a life cycle that consists of starting the life phase of 
the software before it occurs until post-production [8]. 

The description of the waterfall method defined by the 
experts above can be drawn in outline by the authors of the 
method which is systematically structured from the phase 
before it starts to the phase after the information system 
starts. 

The stages of the waterfall method can be seen in the 
figure below according to [9]. 

 

Fig. 1. Waterfall Model [9]. 

D. Raw Material Inventory 
In a company, every operational manager is required to 

be able to manage and hold inventory to create effectiveness 
and efficiency.  

Inventory of raw materials is Inventory of raw materials 
has an important position in the company because the supply 
of raw materials is a very large influence on the smooth 
production process [13].  

Inventories of raw materials are inventories are stored 
materials or goods that will be used to fulfill certain 
purposes, for example, for use in the production or assembly 
process, for resale, or parts of an equipment or machine". 
From the above understanding, it can be understood that raw 
materials are raw materials, semi-finished materials, and 
materials that will be processed in the production process to 
become a finished product [14]. 

III. RESEARCH METHODS 

In this study, there is further research that contains the 
stages. This framework is the steps or stages that will be 
carried out by researchers in the settlement that will be 
discussed. Is a flow cart picture.

IV. RESULT AND DISCUSSION 

A. Use Case System Diagram 

To illustrate the system activities that will be made, the 
author uses modeling with use case diagrams. The use case 
diagram is used to find out what functions existing in the 
system and anyone who may use these functions. The use 
case diagram for the following raw material inventory 
control systems:

CONCLUSION 

 Based on the analysis that has been done, the authors can 
conclude that consumer satisfaction is a major factor in 
winning increasingly fierce industry competition. Consumer 
satisfaction can be achieved in several ways including 
quality products, competitive prices, and timely delivery. 

Therefore, a company needs to pay attention to the 
control and planning of raw material inventory (Raw 
Material) to achieve the effectiveness and efficiency of data 
processing to maintain smooth production and increase 
customer satisfaction. To be able to optimize the inventory 
function, companies must make plans in the procurement of 
raw materials. The planning must be following the 
production needs for each boast with the existence of a raw 
material control system that has been made, is expected to 
facilitate the admin in conducting raw material relations, 
search for data to make reports, so that the creation of better 
jobs. As for the discussion of the previous chapters 
conclusions can be drawn as follows: 

1. The raw material control system at PT. Six Ems 

Indonesia, especially for calculating raw material 

production needs, still use excel files and different storage 

databases. This causes the operational processes that are 

not yet maximized. 

2. Calculation of raw material requirements in the 

application using the bill of material multiplication. 

3. In the application, a form is provided for request input or 

forecasts from the customer and then automatically 

calculates the raw material production requirements.
