Identification of Genius Loci on the Main Street of Kotagede

2024-04-06T20:26:54+07:00

Kotagede is one of the districts in Yogyakarta with many historical sites. However, because of the dense morphology of the area that is characterised by small alleys, creating an atmosphere gap between the main street and the village tourism kampung. One of Kotagede's attractions, the silver crafts industries, is a sector that utilises much of the main street space in the form of retail shops. This study aims to explore the character of silver craft industry on Kotagede's main streets using the genius loci phenomenological method. Three parameters of image, space and character were used as the unit of analysis to identify the spirit of the area on Mondorakan and Kemasan streets. The results of the literature study and field observations show that both streets function as landmarks and representations of the silver industry sites. The results of the study are expected to be one of the references in the implementation of the revitalisation of tourist areas in Kotagede.

Evaluation on Effective Dimensions of Base Isolators Applied at Existing RC Building due to Earthquakes

Even though, the reinforced concrete (RC) buildings were designed to be earthquake-resistant, but if subjected to the earthquake loads, the buildings will still have the potential to experience damage to collapse. Usually, building damages caused by horizontal earthquake loads is more dominant than vertical earthquakes, so mechanical devices are needed that can dissipate the earthquake energy. One of devices is base isolator. To determine the types of base isolators to be used, so the structural performance evaluation of the base isolators is carried out first. However, the test done in a laboratory with a full scaled requires a large cost. Based on this, in this study, a finite element analysis was done to determine the effective dimension of the base isolators, with type of High Damper Rubber Bearing (HDRB) produced by Bridgestone. HDRB was applied at the existing RC building (namely SMP 5 Muhammadiyah building located in Surabaya) that subjected to the spectral response. The analysis results showed that the HDRB with type HH090X6R provides better performance, where the displacement efficiency reached 90.56% for the x-direction and 95.87% for the y-direction.

Analysis of Secant Pile Reinforcement Due to Lateral Soil Pressure (Case Study: H.M. Yamin Underpass Project).

The city of Medan in Indonesia has a large and dense population. As a result, there is an increase in the number of vehicles that is not proportional to the available road capacity. In particular, the provincial roads, which serve as the main logistic routes to various regions in North Sumatra, often experience congestion due to high volumes of vehicles and numerous intersections. One of the roads affected by traffic congestion is the Jl. H.M. Yamin – Simpang Jl. Jawa. Therefore, the construction of an underpass on this road is planned as a solution to alleviate traffic congestion. In the planning of the underpass construction on the H.M. Yamin – Simpang Jl. Jawa road, Secant Pile retaining walls are planned to be used. In the planning of Secant Pile construction, reinforcement planning is crucial to ensure the strength of the retaining walls. Therefore, this study aims to evaluate the strength and safety of the retaining walls built with Secant Piles and determine the optimal reinforcement to be used in the construction. The analytical calculation results of Secant Pile using empirical formulas obtained a shear force of 126.9 kN and a bending moment of 575.1 kNm. The results are not significantly different from the analysis results with Midas Software, which are a lateral force of 125.4 kN and a bending moment of 482.6 kNm. In the reinforcement calculation, the main reinforcement with a diameter of 22 and shear reinforcement with a diameter of 12 are planned.

Sense of Worship

2024-02-07T08:47:52+07:00

The existence of a place in the concept of worship functions to fulfill the worship needs of every human being and should support a ‘khushu’ atmosphere when worshiping. This atmosphere can be felt through a multisensory approach and believed to be very beneficial for users to form empathy and emotions so they can prepare users physically, mentally and spiritually before carrying out worship. This study aims to determine the maximum and minimum multisensory aspects that work at Salman Mosque ITB and find out their effect on one's devotion to worship. The Salman Mosque of ITB was chosen as the research object because it is considered to be able to describe spatial language in a multisensory manner based on the literature. Therefore, a quantitative research method was carried out through a questionnaire with respondents using the Salman Mosque. The results showed that there were multisensory variables that worked optimally on solemnity including lighting and smell, worked minimally on solemnity of acoustics, and had no effect on solemnity of worship including wayfinding through sensory sliders.

Identifikasi Genius Loci pada Jalan Utama Kawasan Kerajinan Perak Kotagede

2024-01-17T13:56:19+07:00

Kotagede merupakan kecamatan dengan berbagai keragaman situs sejarah di Kota yogyakarta. Namun morfologi daerah yang padat dengan ciri khas gang-gang kecil mengakibatkan adanya jarak antara jalanan utama dengan suasana wisata kampung. Salah satu daya tarik Kotagede yaitu sentra kerajinan perak merupakan sektor yang banyak memanfaatkan ruang jalan utama dalam bentuk toko retail. Kajian ini bertujuan menggali karakter keberadaan kerajinan perak yang tersebar di jalanan utama Kotagede menggunakan metode fenomenologi genius loci. Tiga parameter berupa citra, ruang dan karakter digunakan sebagai unit analisis untuk mengidentifikasi ruh kawasan yang ada pada Jalan Mondorakan dan Kemasan. Hasil dari studi pustaka dan observasi lapangan menunjukkan bahwa kedua jalan tersebut berfungsi sebagai penanda ciri wilayah dan representasi dari lokasi wisata industri perak. Dari hasil kajian diharapkan dapat menjadi salah satu acuan dalam pelaksanaan revitalisasi daerah wisata di Kotagede.
