Yusuf Islam
Bagaimana hidup sekarang (setelah Islam)?
Menukar sesuatu yang bersifat sementara
kepada yang kekal abadi !!!.. Menjadi orang yang dipuja oleh peminat?
Transform yang dipuja kepada yang memuja yaknibilamana saya berkomunikasi dengan Allah swt didalam solat.
Minat dengan muzik?
Transform muzik yang diminati dengan hibur tangisanak-anak dirumah.

2. Productivity Index
The productivity index (P.I) can be more orless than 1.
P.I > 1 = business running efficiently
P.I < 1 = business running inefficiently

4. Material Requirement
Planning
Step I : Identify and list down the rawmaterials required
Step II : Prepare the bill of materials
Step III: Calculate the quantity of rawmaterial required
Step IV: Identify supplier

Step I
Identify and list all the raw materialsrequired to manufacture the productor provide the service.
Restaurant:the raw materials requireddepend on the menu for the day
Cleaning service:the materials requiredinclude consumable items like detergents
and scrubbing pads.Retail business:fresh goods, sundry goods,
canned goods.

Step II
Prepare a bill of
materials required fora unit of product.
Ingredient Amount required for100 cookies
Flour 2 kg
Margarine 0.5 kgSugar 1 kg
Eggs 4 units
Water 0.5 litre
7/31/2019 C8 Operation Management
13/37
Therefore, the bill of materials
for a unit of cookies will be:
Ingredient Amount Required/Cookies
Flour 0.02 kg
Margarine 0.005 kg
Sugar 0.01 kgEggs 0.04 of an eggs
(1 egg for 25 cookies)
Water 0.005 litre
7/31/2019 C8 Operation Management
14/37
Step III
Estimate the raw material requirementby multiplying the bill of materials withthe total number of cookies to be
produced monthly.
The number of units to be producedmust be based on the sales forecast in
the marketing plan.
7/31/2019 C8 Operation Management

Example:
If the forecast demand per month is 50,000units of cookies.
If the amount of stock at the end of themonth is 5% of the amount.
nthcookies/mo500,52
500,2000,50)000,50%(5000,50
7/31/2019 C8 Operation Management
16/37
The materials required for the month:
Ingredient Amount Required/Month
Flour 0.02kg/unit x 52,500 = 1050kg
Margarine 0.005kg/unit x 52,500 = 2025kg
Sugar 0.01kg/unit x 52,500 = 525kg
Eggs 0.04/unit x 52,500 = 2100 units
Water 0.005litre/unit x 52,500 = 262.5 litre

Step IV
Identify supplier
Look through yellow pages/publications bytrade associations, and seek quotations
from suitable suppliers.
1. Price and discountoffered
2. Quality of materials
3. Sales terms & conditionse.g payment terms
4. After sale service andwarranty
5. Lead time i.e the timebetween orders anddelivery
6. Delivery terms e.g freetransportation
7. Reliability of supplier

Capacity Planning
The capacity of any productionoperation refers to the amount ofoutput that can be produced within a
specified time.
It is a method to calculate machineryand manpower requirements so that
production demand based on salesforecast can be met.
7/31/2019 C8 Operation Management
19/37
Based on monthly sales forecast, thedaily production capacity can bedetermine by dividing it by the number
of working days per month.
This capacity should be divided by thenumber of working hours per day to
give the capacity per hour.

If sales forecast is 520 units of tudung per
month.
If working days per month is assumed to be
26 days per month, the daily production rateis:

Activity: Tudung cutting
If one cutter can cut 1 tudung in 1/3 hour, thereciprocal of this is:
= the cutters capacity to cut per hour
= 3 tudung per hourTherefore, the number of cutter required is:
= Production capacity per hour/cutters capacityper hour
= 5/3 = 1.67 (needs 2 cutters)
7/31/2019 C8 Operation Management
23/37
Determine the number of workers required
If one tailor can sew 1 tudung in hour,
then his hourly capacity is:
= 1/0.5 hr
= 2 tudung per hour
Therefore, the number of tailors required is:
= 5/2= 2.5 tailors (3 tailors) and also, at least 3
sewing machines + 1 (standby)
7/31/2019 C8 Operation Management
24/37
If one tailor requires a working spaceof 8 ft by 10 ft, than the total spacerequired for 4 tailors is:
= 8ft x 10 ft x 4 tailors
= 320 square ft

5. Layout
Layout refers to the arrangement ofmachinery, equipment, workers and otherfacilities used in the operation.
The arrangement should be made in such away that the production of goods andservices can be done efficiently.
It should take into consideration the
integration of several factors including workstation, tool room, store, office, prayer roomand toilet.

Types of layout
Layout based on product
The design is done according to the
sequence of activity to produce the
product.

Layout based on marketingThe layout is designed to utilise the
available space to display goods.
Example: retailed shop and bookshop. Arrangement of goods are interactive
Goods are easily accessible and convenientfor the customers
It is easy for the entrepreneur to protect goodsfrom theft
The entrepreneur can maximize the return ofinvestment form the space used.

6. Physical Location
It is crucial to choose the right locationfor the business because a strategiclocation can contribute to the success
of the business.
The choice of location will depend onthe following factors:
Distance from the source of raw materials
Availability of manpower
