STUDYING THE HUMAN SCALE AND PROPORTIONALITY OF GREAT MOSQUE IN JAWA TIMUR, INDONESIA



 STUDYING THE HUMAN SCALE AND PROPORTIONALITY OF GREAT MOSQUE 
IN JAWA TIMUR, INDONESIA


The proportion and scale of humans in the building is one of the invoices in shaping the beauty and effectiveness of the function of the building. In architecture there is a golden ratio as a reference for calculating the proportions of a shape, in Indonesia, especially in Java and Bali, there is a traditional measurement method in making a building, using body anatomy measurements. This study uses the Golden Ratio and Traditional Measurement methods to analyze the dimensions of the prayer room at the Great Mosque in East Java with case studies of the Lamongan Great Mosque, Tuban Great Mosque, and Gresik Jamee Mosque. The results obtained from this study for the dimensions of the existing prayer room with the largest percentage approaching the golden ratio are the prayer room of the Great Mosque of Lamongan (82%) and the smallest is the Jami Gresik Mosque (61.8%). While the dimensions of the prayer room need adjustments to be more effective in meeting the human scale in performing prayers, traditional measurement methods that approach modern measurements are using "kilan" and "hasta". From these results, it is hoped that in the future, mosque planning can pay attention to the proportions and dimensions of the human scale, both with modern measurement methods and traditional measurements which are local wisdom of the local culture.

 

Proportion, Human scale, Great Mosque of East Java, Golden Ratio, Traditional Measurement.


INTRODUCTION

 

In architecture, the size of the building is very important, especially the size compared to the proportion of humans as residents and users of the building [1].  Humans instinctively follow and imitate the natural surroundings as a reference in making a building.

The proportion of good and correct sizes in addition to getting comfort in carrying out activities, also getting the beauty of the facade in terms of building visualization [2].

The theory about the reference size of the building can refer to the golden ratio which is applied to classical buildings during the renaissance, can also refer to ergonomics [3] and anthropometry [4] of the perpetrators of these building activities [5].

This article was published in the following journal: https://ejournal.uin-malang.ac.id/index.php/JIA/article/view/17382



In architecture, scale and proportion are very important, proportion refers to the harmonious relationship between one part and another, while scale refers to the size of one with the other [6].

Research in the field of human proportion and scale has been found, usually using qualitative and quantitative methods, the difference between architectural research and other fields lies in the desired method and purpose, in the field of mathematics [7] research on human proportions and scale in this building uses this method. quantitative because the focus point is on the dimensions and size of a part of the building in other words the goal is to find the "proportion of ratio", while architecture uses qualitative methods because the focus point is on the quality of the scale proportion to the function of the building and the beauty it produces, in other words, the goal is to find a "proportion of beauty" [8].

In traditional Javanese and Balinese architecture [9], [10] there are measurement methods with limbs as a determinant of the dimensions of their buildings, units of measurement that use body anatomy, including; Depa (a unit of length based on the length of the hand from the tip of the finger), Hasta (a unit of length based on the tip of the finger to the tip of the elbow), Kilan (a unit of length based on the length of the little finger to the thumb when stretched), Tapak (a unit of length based on the sole from heel to toe), Kaki (Unit of measure based on two fists with the junction of the two thumbs extending) [11], which is explained in the table as follows:

This Javanese Traditional Unit of Measure, when synchronized with modern anthropometry in literature such as the Architect Data book [13], the activities of praying people can be adjusted to traditional measurements, for example the type of activity carried out in the prayer room is performing prayers, the most important of which is standing, bowing. , prostrate, sitting cross-legged, which has dimensions, among others: for an adult human standing 87.5 cm, bowing 87.5 cm, sitting cross-legged + 75 cm and prostrating 120 cm.

The dimensions of people standing praying who can close the shaft or line of prayer are 55-60 cm, with a prostration room of 120-130 cm [15]. It can be concluded that to make the activity of standing in prayer can form a tight line. The Great Mosque is a relic of local wisdom in the field of architecture in Indonesia, especially in Java [16], the Great Mosque and 3 other elements, namely Alun-Alun [17], Pendhopo, and the Market are one unit in the "Catur Gatra Tunggal" [18]. The Great Mosque itself has the characteristics of traditional Javanese architecture, which uses the "Soko Guru" wood structure building technology as the main structure [19]So from the narrative above, we get a research gap to analyze the dimensions of space with references from the west, namely the golden section and references from traditional Javanese measurement units that use body measurements so that an ideal proportion can be produced according to the human scale.

The purpose of this research is to study whether the application of the concept of the golden ratio and the use of the human scale in this case the method used is the traditional measurement which is applied to the size of the room, shape, and proportion, especially in the prayer room.

METHODS

To determine the human scale and proportions in the object of study, namely the 3 Great Mosques in East Java, Indonesia, the Great Mosque of Tuban, the Great Mosque of Lamongan, and the Jamee Mosque of Gresik, the golden ratio method, and traditional Javanese unit measurements were used.

This method is aimed at the plan of the mosque, especially in the main prayer room, which emphasizes the dimensions of the prayer room.

There are several ways to measure the golden ratio, the first is to compare two different sizes a and b. Two quantities a and b (with conditions a > b) are said to have a golden ratio if the comparison between the two quantities is the same as the total ratio of the two (a +b) with the maximum value in between (“a” in this case). The golden ratio will be obtained if the long part divided by the short part is equal to the length of the original line divided by the long part. A golden ratio is an irrational number with a value of 1.61803398874989484820… whose digits continue to increase without a certain pattern [20]. However, the equation a/b = (a + b) /a as in the example of dividing the line above must always be fulfilled.

The second way is by simulating a rectangular line that can be narrated as follows:

Lines A and B are the longest lines in a certain area, to find the width of the field that corresponds to the golden section, do with [21]:

1.       Divide the lines A-B in half,

2.       Then make a diagonal from the midpoint to the outermost corner on side B,

3.       The resulting line is rotated in the direction of lines A-B, and is marked with point C,

4.      The intersection of the lines B-C is the ideal width according to the calculation of the golden section.

 

Following these two methods, it is used as a method to find the ideal dimension based on the golden section.

While the third method uses traditional Javanese measurement units based on anthropometry of certain body parts (anatomy) and has the following units [11]:

 

1.       Depa                 = + 1,70 m

2.       Hasta                = + 0,4 m

3.       Kilan                  = + 0,2 m

4.      Tapak               = + 0,28 m

5.       Kaki                   = + 0,3 m

 

The traditional dimensions will be used to analyze the dimensions of the prayer rooms in the Lamongan Great Mosque, Tuban Great Mosque, and  Gresik Jamee Mosque.

If the anthropometric human body measurements as in figures 1 and 2 are converted to Traditional Size units, they will become a unit in table 2:

The next step is the body size of the activities in the prayer (figures 1 and 2) will be compared with the existing dimensions of the prayer room, intending to know the ideal dimensions that can be suggested in the prayer room at the Great Mosque so that the main activities in the prayer room are more effective and appropriate with need.

 DISCUSSION
CASE STUDY

The Great Mosque Of Lamongan

The Great Mosque of Lamongan was built around 1908 AD [22], the initial building of the mosque is in the middle, with a size of 18.5 x 21 m, then a prayer room expansion building in the west with a size of 15.8 x 21 m, and a new building in the south. 47 x 18 m. The location of the tower is in the east, has a main door on the east side as the main door for male and female worshipers, while on the south side the entrance is for male worshipers.


The Great Mosque of Tuban

The Great Mosque of Tuban was built in 1894 [24] the first renovation was carried out using the services of a Dutch architect, B.O.W.H.M. Toxopeus [25], the initial building is in the center with a European architectural style, with the dimensions of the prayer room 23.1 x 20.9 m. Then the prayer area is added by adding to the left and right sides of the initial prayer room, so that it has dimensions of 47.85 x 23.1 m. in the east there are 4 towers and an expansion of the mosque in the form of a porch with a membrane umbrella roof covering


The Jamee Mosque of Gresik

The Jamee Mosque of Gresik, built-in 1756 [26], has the dimensions of the main prayer room 20x20 m and has a floor height of 1.6 m, with the addition of the building on the porch on the mezzanine floor with a height of 2.9 m from street level.


Floor Plan Analysis Through human Scale Study With Golden Ratio

The Great Mosque Of Lamongan

The Lamongan Great Mosque has a main prayer room in the initial building with dimensions of 18.5 x 21 m. according to the golden section analysis.


The plan of the Great Mosque has the longest side of 21 m, if using line analysis, it is found that the appropriate dimension of the golden section is 12.97 m. and if using the ratio then 21/12.97 = 1.619 which is close to the value of the golden section ratio. This is also by the additional prayer room because it has the same dimensions as the long side, which is 21 m.

The Great Mosque of Tuban

In the plan of the main prayer room of the Great Mosque of Tuban with the longest side of 23.1 m, if analyzed using the intersection of the golden section, the ideal dimension is 23.1 x 14.25 which is found in figure 15 which is green.

 In an additional prayer room with the longest side being 14.6 m, the ideal dimensions for the floor plan are 14.6 m x 9.02 as shown in figure 16 green squares.

The ratio between the main prayer room plan calculated based on the golden section is 23.1/14.25 = 1.621 and that of the additional prayer room 14.6/9.02 = 1.618. The result of the division is close to the golden ratio of 1.618.

The Jamee Mosque of Gresik

At the The Jamee Mosque of Gresik, it has a square plan shape, with dimensions of 20 x 20 m, by analysis using a square side that has a length of 20 m, the following analysis is obtained:

From the results of the intersection of the analysis lines of the golden section, it was found that the ideal dimension for the 20 m long side is 12.36 m. in other words the ratio between 20/12.36 is 1.618 which is close to the golden ratio.

 

Floor plan analysis through human scale study with anthropometry and traditional measurements

 

Analysis using anthropometrics is used to find the ideal dimensions based on the size of the human body, it is known from the literature study above that the needs of individuals in the prayer room for their activities require dimensions of 80 cm x 120 cm, as shown in Table 3.

The size converted in traditional depot units is rounded up, because in traditional units it cannot be divided into more detailed measurements because it only relies on body parts. So that the size becomes simpler as in Table 4.


The Great Mosque Of Lamongan

The Great Mosque of Lamongan has dimensions of a prayer room with dimensions of 21 m and 18.85 m for the prayer room in the middle and 21 m x 15.8 m for the prayer room on the west side, meaning that 21 m dimensions are used to count the number of people in a row (shaft). while at 18.85 m and 15.8 m, it is used to calculate the number of rows (shafts). So it can be concluded in Table 5 below:

From table 5, it can be calculated that the long side of the central prayer room of the Great Lamongan mosque has dimensions of 18.85 m, it is obtained 15.71 rows (shafts) with 35 people to be able to stand and 26.25 people in a sitting position in each row (shaft). . If to be able to complete the number of rows, it can be recommended dimensions from 18.85 to 19.20, so that the dimensions of the prayer room become 21 m x 19. 20 m. which can accommodate 16 rows (shaft) and 35 people for each row (shaft) figure 18.

As for the western prayer room, which has dimensions of 15.8 m, there are 13.17 rows (shafts) with 35 people standing and 26.25 people sitting in each row (shaft). If to complete the line, the recommended prayer room dimensions are 21 m x 15.6 m.


While in table 6. It is explained that the conversion of the dimensions of the prayer room to traditional units that are close to the size according to the literature is to use the measurement method with cubits and kilns, which can get 35 people in one row (shaft) in both the central and western prayer rooms, 13, 17 rows (shafts) for the west prayer room and 15.71 rows (shafts) in the central prayer room.

 

The Great Mosque of Tuban

At the Great Mosque of Tuban, the dimensions of the prayer room are 23.1 m x 20.9 m. with the sense that 20.9 m is used to calculate the number of rows (shafts), while on the side of the dimension 23.1 m is used to count people in rows (shafts). And the additional prayer room has dimensions of 13.5 m x 14.6 m, with a side of 14.6 m to determine the number of people in each row and 13.5 m to determine the number of rows. The calculation of the number of rows and the number of people in each row can be concluded from table 7 below.


Table 7 shows that the main prayer room can accommodate 38.35 people in each row, and can make 17.42 rows in the prayer room, while the additional room can accommodate 24.33 people in each row and can make 11.25 people. line in the prayer room. The results of the above analysis can produce recommendations for effective dimensions for the prayer room, the main prayer room is 23.4 m x 21.6 m which can accommodate 39 people in each row (shaft) and 17 rows (shaft). While the additional prayer room on the right and left sides of the ideal dimension is 15 m x 14.4 m which can accommodate 25 people in each row and 12 rows (shaft), which can be simulated in figure 19.

In table 8 it is known that the traditional measurement method that is close to the dimensions of activity needs is using cubits and kilns, in the main prayer room produces 38.5 people in one row (shaft) and produces 17.42 rows and in the additional prayer room, it produces 24.33 people. in each row (shaft) and 11.25 rows (shaft) in the room.

 

The Jamee Mosque of Gresik

 

The Jamee Mosque of Gresik has the dimensions of a prayer room with dimensions of 20 m and 20 m, meaning that 20 m has the same dimensions to calculate the number of rows (shafts) and the number of people in each row.

From the analysis in table 9, it is found that the prayer room can accommodate 33.33 people in each row (shaft) and can form 16.67 rows (shaft).

The recommended dimensions for the room to be effective are 20.4 m x 20.4 m so that it can accommodate 34 people and make 17 rows (figure 17).

in table 10 it is known that the traditional measurement method is the same as the previous mosque, namely using cubits and kilns, in the main prayer room produces 33.33 people in one row (shaft) and produces 16.67 rows.

 

CONCLUSION

In addition to being adapted to the function of the activity in the mosque, the beauty of the design in it, the human scale, and proportions greatly affect the size of the prayer room, from the research above.

The dimensions of the plan which refers to the golden ratio of the rectangular plan, having the longest and shortest sides when divided will produce an irrational number of 1.618. In Table 11 it is found that the one with the largest percentage for the golden ratio is the western prayer room at the Lamongan Great Mosque with 82%. While the smallest is the Jami Gresik Mosque Prayer Room, which is 61.8%.

The floor plans of the Great Mosque of Lamongan, the Great Mosque of Tuban, and The Jamee Mosque of Gresik, have dimensions that do not meet the criteria of the comparison of the golden ratio and human scale. If referring to the golden ratio and human scale, the adjustment of the dimensions of the prayer room plan is contained in table 12:

The traditional measurement method in the mosque's prayer room is more effective using "hasta" and "kilan", this is because the results of the division of the number of prayer rooms are almost the same as the distribution using modern measurements found in the literature, while for "depo" and "kaki" have the same results. the division of the number of prayer rooms is less and “pecak” has the result of dividing the number of prayer rooms more.
