CHAPTER I

INTRODUCTION

1.1 Background

Chilli is plant which include to genus capsicum. Chilli is easy to find in

Indonesia country. This plant which is general different flavors and none for

people of indonesia. Chili itself cannot be separated from Indonesian food, such as

padang food. Padang food typically use chili in each dish.

Figure 1.1 Red Chilli

Chili is a popular spices, known for their function as a food flavouring and also

medicinal benefiting properties. As the most commodities in demand and sought

after, chili always fluctuated in it’s development. Here are a few tables and chart

about chili, it’s price, consumption, and various other problems that often occur.

From the figure above, sumatra region occupy second rank in 2012 after

Java region. Table 4.36 looking about the chili consumption in Indonesia from

2008 until 2012.

From the table above, we know the average consumption is high. But,

there are some chili’s type which decrease from year to another year.

Table 4.35 shows world grade for chili production. There are top 10

according to the FAOSTAT.

From the table above, we can see Indonesia is one of country that have

contribute for chili production in the world. The first rank is placed by China

while Indonesia in 4th rank.

One problem which often occurs in plantation chili is a way to harvest chilli.

Chili grew up in the boughs chili and taken to the way quoted use our hands.

Another way to take chili is to use scissors. However, the two ways are still need a

long period of time and skills to a good chili quoted quickly. Other problems is

the number chili that fell in vain to the ground. This makes farmers loss because

many chili banished.

Figure 1.2 Farmer harvest chilli by hands

For that reason we design chili handcutters tool that allows farmers chili in

harvest chili quickly without any chili that fell to the ground. This device combine

quotes chili with its fore- and scissors. With this device production rate will

increase and increase farmers' welfare chili.

1.2 Problems

1. How to design chilli handcutters

2. How to make the system of chilli handcutters

1.3 Outcomes

1. Chilli handcutters able to be solution for harvesting chilli in Indonesia

2. These tools can increase production rates of chilli

2.2 Function Analysis Method

In Function Analysis Method the functions must be separated into

sub-functions. For chili handcutter following by :

1. Chili is cutted by chili handcutters.

2. We separate chili and its stem.

3. For collecting the chili, we use chili collector.

4. Chili is collected.

2.3 Designing of Chili Handcutter

For designing this device, there are some steps to realize the device.

The steps are : Making Concept, Design Specification, Positioning,

and Engineering Drawing. For easy to understand, we make the

flowchart below :

2.3.1 Making Concept

For making concept, we just adopt the principle of scissor to

cutting the chili. After that using sack for collecting the chili. We using

objective tree diagram for making the concept.

1. Easy to use : - Using human energy

- Simple design

2. Cheap : - Knife

- Sack

- Wire

3. Easy to maintenance : - Simple construction

2.3.2 Design Specification

Chili Handcutter using cheap material and also easy to

manufacture. So, there are some general specification for our device :

1. Knife

2. Spring

3. Fiber

4. Wire

5. Sack

2.3.3 Positioning

For determining the position of device is depend on the function of

parts. So, we make a positioning like this figure below :

For detail design we refer to the positioning part, as we can see in
