Examples of Simple Appropriate Technology Tools – Surely the term technology is familiar to us. The development of the times makes humans continue to innovate in creating technology, where technology is made to make it easier for humans to do a job.
Now, talking about technology, on this occasion, we will discuss information about appropriate technology. What is appropriate technology? Appropriate technology began to become famous when there were various environmental protection movements in 1970 and the oil crisis in 1973.
People began to think about technologies that were more environmentally friendly and socially friendly to use (at least more environmentally friendly than factory technology at that time).
These technological tools will be used to ease human work while still saving existing resources, easy to manufacture and easy to maintain by humans.
To make it easier for you to understand, here we share some examples of appropriate technology tools that can be used in everyday life.
A. Definition of Appropriate Technology
In general, appropriate technology can be defined as technology that is appropriate to the conditions in which the technology is used / applied, both from social, economic and cultural aspects, so that local people can easily participate and can meet their needs effectively.
B. Examples of Simple Appropriate Technology Tools.
1. Rotten Egg Detector
This tool, which is shaped like a flashlight, was created by a junior high school student in the archipelago, Magelang. This flashlight is equipped with a light sensor and calibrator that is built into the flashlight.
When the flashlight is pointed at the egg and it penetrates, the detector will show a green light which means the egg is in good condition. Conversely, when the light is directed at the egg and it is not translucent, the detector will show a red light which means the egg is rotten.
2. Automatic Onion Slicer
This tool is simply assembled using motor components with an electricity of less than 200 volts.
This machine includes a chopping knife that will cut the onions to the same thickness. This machine is suitable for business food stalls, or home factories.
3. Egg Incubators
This one tool can be made using used goods, namely cardboard. How to make it simple and easy. Other materials you also need are rice husks, adhesive, water container, cable and a 5 watt yellow light.
How to make it, make a hole in the cardboard in each piece of cardboard with 4 holes 1cm in diameter. Install the lamp on the top of the cardboard. Then, cover the cardboard with rice oak as a base and place a small water container in the corner of the cardboard to keep the cardboard moist. Place it on a flat surface. The egg incubator is ready to use.
4. Mosquito Exterminator Tool
This tool is a simple tool made using used bottles, black / plastic cloth, water, brown sugar and yeast. The way to make it is, cut the bottle in half.
Dissolve brown sugar with water, let it cool. Enter into the bottom of the bottle that has been cut then add yeast. Do not enter it so that the yeast and sugar produce maximum carbon dioxide.
Place the top of the bottle upside down like a funnel, then cover the body of the tool using a black cloth / plastic bag. Place it in some corner of the house or a place that is infested with mosquitoes. Easy right?
5. Refrigerator Without Electricity
This energy-friendly refrigerator is made from a Styrofoam container that will hold your vegetables and fruit fresh for up to 7 days. How to use it is easy.
Put the vegetables and fruit in the biscuit tin, then put it in the sterofoam. Add clean sand and salt to cover the surface of the can. Then close the sterofoam.
For maximum results, place the sterofoam in a place that is not exposed to direct sunlight.
6. Organic Waste Composter
Organic waste can be used as compost for plants. In fact, the tool for converting organic waste into compost is one of the most effective technologies that can be made at home.
Simply prepare used buckets, large paralon pipes, small paralon pipes and hard fiber for the base and filter from compost material. The method is quite easy.
Make a hole in all parts of the pipe and fiber thoroughly. Then make a hole in the side of the bucket until it penetrates into the other part, insert a small pipe pipe.
Then make a hole in the bottom of the bucket, and put a large paralon into it so that it penetrates the bottom of the bucket to drain the compost water. Place the fiber base into the bucket. Punch some of the bottom of the bucket and a simple composter is ready to use.
7. Soil Fertility Measurement Tool
There are many factors that make farmers fail to harvest, one of which is farmers’ ignorance of the fertility element in their soil. But there is one simple, efficient technology that farmers can make to measure the fertility of their land.
The material that must be prepared is a pipe paralon, lampholders, electric cables, chokes and metal plates such as nails.
How to make it easy. First, connect one end of the light fixture to the bicycle spokes and the other end to a 2 meter long cable, the other end of the wire to the power jack.
If the connection is secure, install a 100 watt light bulb. How to use it is easy. Take a handful of soil to be tested, mix with mineral water.
Plug the tip of the soil fertility tester into the container, the brighter the light bulb, the more fertile the soil being tested.
8. Filter (filter) Water
Another appropriate technology is a water filter that can be used to filter dirty water into clean, usable water. This tool is of course very useful for areas that lack clean water.
The materials that must be prepared are a bucket, gravel for the first filter, coconut husk as the second filter, palm fiber as the next filter, charcoal as the fourth filter and sponge as the last filter.
Also prepare a pipe pipe and a reservoir as a container for clean, filtered water. The manufacturing step is the first, make a hole in the bucket at the bottom and install the pipe as a water outlet.
Enter the sponge, palm fiber, charcoal, coconut husk, and gravel in sequence with the same composition. Put dirty water from the top of the bucket and see that cleaner water will come out of the pipe pipe.
To filter clean water, you can do it over and over again until the water is really suitable for use.
9. Vacum Cleaner From Used Bottles
Vacum cleaner is no longer a foreign thing that is difficult to find in society. In fact, the vacuum cleaner can be made simpler and uses used materials.
Materials that must be prepared are used mineral bottles, used cans, dynamo, glue, motorbike batteries and sufficient cloth. How to make it is not complicated.
First, cut the bottle in half, making a hole at the bottom of the bottle. Cut the can into a circle smaller in diameter than the bottle and make a fan blade. Glue the propeller to the dynamo and place it on the bottom of the bottle where the glue has been holes.
Also glue the cloth that is used as a filter for dirt that will be sucked in. Then, unite the top of the bottle and add a handle to make it easier for you to use a vacuum cleaner.
