Reference excerpt

The National Monument (Indonesian: Monumen Nasional, abbreviated Monas) is a 132 m (433 ft) obelisk in the centre of Merdeka Square, Central Jakarta. It is the national monument of the Republic of Indonesia, built to commemorate the struggle for Indonesian independence. This monument is crowned with a flame covered in gold leaf which symbolizes the burning spirit of struggle of the Indonesian people. Construction began in 1961 under the direction of President Sukarno, and the monument was opened to the public in 1975. The monument and the museum are open daily from 08:00 to 16:00 Western Indonesia Time (UTC+7) throughout the week except for Mondays when the monument is closed. Since April 2016, the monument is also open during night time, from 19:00 to 22:00 on Tuesdays to Fridays, and from 19:00 to 00:00 on Saturdays and Sundays.

Background

After the Indonesian government returned to Jakarta from Yogyakarta in 1950 following the Dutch recognition of Indonesian independence, President Sukarno began to contemplate the construction of a national monument comparable to the Eiffel Tower on the square in front of the Presidential Palace. On 17 August 1954, a National Monument Committee was established and a design competition was held in 1955. This attracted 51 entries, but only one design, by Friedrich Silaban, met any of the criteria determined by the committee, which included reflecting the character of Indonesia in a building capable of lasting for centuries. A repeat competition was held in 1960, but once again, none of the 136 entries met the criteria. The chairman of the jury team then asked Silaban to show his design to Sukarno. However, Sukarno did not like the design as he wanted the monument to be in the form of a linga and yoni. Silaban was asked to design such a monument, but his design was for a monument so large that it would have been unaffordable given the economic conditions at the time. Silaban refused to design a smaller monument, suggesting that construction be delayed until the Indonesian economy improved. Sukarno then asked the architect R.M. Soedarsono to continue with the design. Soedarsono incorporated the numbers 17, 8 and 45, representing the 17 August 1945 Proclamation of Indonesian Independence, in the dimensions of the monument.

Construction

The construction of Monas proceeded in three stages. The first period, from 1961/1962–1964/1965 began with the official start of construction on 17 August 1961 with Sukarno ceremonially driving in the first concrete pile. A total of 284 piles were used for the foundation block. A further 360 piles were driven in for the museum foundations, with work being completed in March 1962. The walls of the museum in the base were completed by October. Construction of the obelisk then commenced and was finished in August 1963. Work in the second stage, from 1966 to 1968, was delayed by shortages of funding and the aftermath of the 30 September Movement coup attempt.

In the final phase, from 1969 to 1976, the dioramas for the historical museum were added. Problems remained once construction was complete, and work was needed to solve problems with water leaking into the museum. Monas was officially opened to the public on 12 July 1975. The location of Monas is known as Merdeka Square.

Description

Design

The towering monument encapsulates the philosophy of Lingga and Yoni. Lingga resembles an alu rice pestle and Yoni resembles a lesung rice mortar, two important traditional Indonesian tools. Lingga and Yoni also symbolize harmony, balance, fertility and eternal life with the lingga phallic symbol, representing masculinity, positive elements, and daytime and the Yoni the female organs symbol, representing femininity, negative elements, and night. It also resembles the bloom of the famous Amorphophallus titanum, native to Indonesia. Indeed, fiberglass Amorphophallus and Rafflesia sculptures were once installed around the monument. The monument consists of a 117.7m obelisk on a 45m square platform at a height of 17m, the goblet yard. The obelisk itself is clad with Italian marble. The northern pond measuring 25×25 m was designed to cool water for the air conditioning system of Monas as well as to enhance the beauty of the surrounding area. To the north, there is a statue of Indonesia national hero Prince Diponegoro by Italian sculptor Cobertaldo.

Reliefs of Indonesian history

In the outer yard surrounding Monas there are reliefs of Indonesian history. The story begins in the northeastern corner and describes events during eras such as the Singhasari and Majapahit empires. The reliefs extend along the four walls showing the European colonialization of the Indonesian archipelago, various popular local uprisings, modern Indonesian organizations in the early 20th century, the Japanese occupation in World War II, the Proclamation of Independence, and post-independence developments. The reliefs were made from molded cement although several of the statues are damaged and have decayed due to weathering.

The National History Museum The Indonesian National History Museum has a display of dioramas in the large marble-lined hall below Monas. There are a total of 51 dioramas around the walls and in the centre of the hall. The dioramas begin in the northeastern corner, displaying the scenes from Indonesian history from the beginning during the earliest days of Prehistoric Indonesia, the construction of Borobudur, the Sriwijaya and Majapahit eras, followed with events from the period of European colonization and uprisings against Dutch East Indies Company and Dutch East Indies rule. The dioramas continue well into the 20th century showing the Japanese occupation, the proclamation of Indonesian independence in 1945, the struggle for independence of Indonesian revolution, and on to events during the New Order era of Suharto's regime.

Worked examples

Example 1 — a first encounter with National Monument (Indonesia)

Start with the simplest possible case. Write down what National Monument (Indonesia) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to National Monument (Indonesia) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about National Monument (Indonesia) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of National Monument (Indonesia)

In research
National Monument (Indonesia) appears in mathematics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses National Monument (Indonesia) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
National Monument (Indonesia) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1975 establishments in Indonesia, Aftermath of the Indonesian National Revolution, Buildings and structures completed in 1975, so understanding it makes those chapters shorter.
In everyday life
Look for National Monument (Indonesia) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
