The Effect of Astronomical Position on Life – Below is information regarding the influence of astronomical position on life, so watch this article to the end to find out more complete and clear information.

Besides having a location geographical, Indonesia also has an astronomical position. For the people of Indonesia, must know. What is the definition of Indonesia's astronomical position?

Often this is a question that is thrown a lot. Astronomical location is the position of an area that can be seen from the earth's imaginary line or latitude and longitude.

Astronomical Location of the Equator

Latitude is a horizontal line and longitude is a vertical line. These two lines have their respective functions, just as the latitude serves to divide the earth into north and south.

While this longitude serves to divide the earth into two parts, namely east and west.

From these two lines, it can provide differences for several regions. In other words, this latitude affects the climate differences that exist in Indonesia. While the division of time is influenced by differences in longitude.

In summary, Indonesia is located at 95 degrees East Longitude to 141 degrees Longitude and 6 degrees North Latitude to 11 degrees South Latitude.

So, to find out more about Indonesia's astronomical location, see the following review.

Astronomical Location of the Equator

As previously explained, Indonesia is located between 6°N-11°S and 95°E-141°East. Indonesia is traversed by the equator or it can be referred to as the 0 degree line.

This line is an imaginary line that divides the earth into two parts, namely north and south. There are several areas in Indonesia that are traversed by the equator, this can be seen from Indonesia's astronomical location.

Such as the Batu Islands in Sumatra, Pontianak in Kalimantan and the Lingga Islands. Apart from that, Sulawesi, Kayoa, Halmahera Islands, and Gebe Island are also areas where the equator passes.

In fact, there are several seas or bays through which the equator passes, such as the Karimata Strait, Tomini Bay, Makassar Strait, Maluku Sea and Halmahera Sea.

Many positive impacts are obtained by several areas traversed by the equator. Like having the same duration of day and night which is 12 hours for a total of 24 hours.

In addition, during the day the sun is directly overhead. This occurs when the equinox or the center of the sun is in a position parallel to the equator. However, this Equinox only occurs twice a year.

Influence on the Climate in Indonesia

Indonesia is in a hemisphere with a tropical climate, this can be seen based on Indonesia's astronomical location which is at 6 degrees LU to 11 degrees LS.

Apart from being a tropical climate, Indonesia also has 2 different climates, namely the monsoon and the sea climate.

Influence on the Climate in Indonesia

So, to find out more about the three climates, see the full review below:

Tropical climate

The tropical climate occurs in an area that is in an astronomical location around 23.5 degrees LU to 23.5 degrees LS.

By being at 6 degrees latitude to 11 degrees latitude, Indonesia is a country with a tropical climate.

By being in that position, Indonesia has the same time of day and night, which is 12 hours.

In addition, the impact of this tropical climate, Indonesia has higher humidity and rainfall.

In fact, this country which has a tropical climate only has two seasons, namely summer and rainy season. Alternation of the two seasons, an average of six months a year.

Monsoon climate

The second climate that Indonesia has is the monsoon climate. This is because every certain period, there is a change in the wind.

We need to know that monsoons are divided into two, namely east monsoons and west monsoons.

It is called the east monsoon because this wind blows from the Australian continent which is in the east to Asia which is in the west. As for the west wind, this is the wind that blows from the Asian Continent to Australia

The occurrence of the west monsoon and monsoon winds, of course, greatly influences the climate in Indonesia.

The rainy season that occurs in Indonesia is due to the west monsoon winds that pass through the Indian Ocean.

Meanwhile, the dry season that occurs in Indonesia is due to the east monsoon wind that passes through the Gibson Desert

Marine Climate

The existence of a marine climate because Indonesia is an archipelago country. In addition, almost 2/3 of Indonesia's territory is water.

With regional conditions like this, high rainfall in Indonesia is higher than other countries.

Influence on Time Distribution in Indonesia

After discussing the influence of astronomical position on the climate in Indonesia, it would be incomplete if we did not discuss the effect of astronomical position on the distribution of time in Indonesia. The division of time in an area is caused by longitude.

Like the line of 0 degrees longitude that crosses the city of Greenwich in England. Thus setting it as the world standard time GMT or Greenwich Mean Time.

Indonesia has a longitude of 95 degrees East to 141 degrees East, so Indonesia's astronomical location causes three different time divisions.

The three times include West Indonesia Time, East Indonesia Time and Central Indonesia Time.

Influence on Time Distribution in Indonesia

So, for more details regarding the division of time in Indonesia, see the full review below:


Indonesia is a large area, so there is a division of time for several regions. Areas that are between 95 degrees East to 105 degrees East enter Western Indonesia Time, such as the islands of Sumatra, Java, Madura, and parts of the western part of Kalimantan.

As the name implies, WIB is used by several regions of Indonesia which are in the western part. WIB, internationally is GMT +7.


The area included in Central Indonesian Time is between 105 degrees BT and 120 degrees BT.

Named Central Indonesian Time, because these areas are in the central part of Indonesia. In other words, this region is between east and west.

The areas that are in the WITA time zone are Sulawesi Island and Bali Island. In fact, the eastern part of the island of Borneo, East Nusa Tenggara and West Nusa Tenggara are also part of Indonesia's Central Time. WITA time, internationally it is often written as GMT +8.


The Indonesian region, which includes Eastern Indonesian Time, is between 120 degrees East to 135 degrees East.

There are quite a few areas included in the WIT time zone, namely Papua Island and the Maluku Islands. If in international time, the WIT time zone is written as GMT +9.

The Influence of Astronomical Position on Life

Astronomical location does not only affect the climate and time division, more than that it also influences the lives of the residents directly.

As previously explained that Indonesia has a tropical climate with high rainfall. However, with a climate like this, Indonesians have been able to adjust.

So, in this explanation, there are several Indonesian people's lives that are caused by astronomical locations. In more detail, here is the review:

Agricultural Activities

As we already know that Indonesia gets more sunshine and high rainfall.

Agricultural Activities

Under these conditions, Indonesians carry out more agricultural activities throughout the year.

In fact, since their ancestors, the people of Indonesia have started farming to make ends meet.

Economic activity

Indonesia has a very stable climate, so it is very comfortable. Of the three climates in Indonesia, there is no significant difference.

Thus, the economic activities of the Indonesian population can last throughout the year and are not limited by climate change.

Social And Culture

Since long ago, more Indonesians have worked as sailors. This is because in Indonesia it is passed by the east monsoon and west monsoon winds.

So do not be surprised if since ancient times, Indonesia has become an international shipping route.

This also has an impact on the culture in Indonesia. Lots of foreign cultures have entered Indonesia and have started to develop.

In addition to the positive impact, there is also a negative impact. With so many foreign cultures coming to Indonesia, people are getting enthusiastic and even forget about local culture.

Architectural Forms of Buildings

The architectural forms of buildings in Indonesia are also influenced by the prevailing climatic conditions. With the current climate, most of the houses in Indonesia have a prism shape on the roof.

The prism-like shape of the roof serves to make it easier to drain water when it rains. This is because rainfall in Indonesia is quite high.


That's a little information about the astronomical position of Indonesia which has a lot of influence on life, one of them.

Broadly speaking, with its astronomical position, Indonesia has 3 time divisions and 3 different climates. In addition, there are only two seasons in Indonesia, namely the dry season and the rainy season.

Thus the article about the Effect of Astronomical Position on Life and don't forget to keep visiting the Infokekinian website.

Because we also have a lot of other information and recommendations which of course will be useful and helpful to current and useful friends.
