The proportion and scale of humans in the building are 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. While in Indonesia, especially in Java and Bali, there is a traditional measurement method for developing 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 use "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 and traditional measurements, which are the local wisdom of the local culture.

As the population increases, the speed of population movement also increases and the availability of proper infrastructure in crowded centers decreases. One of the problems in terms of pedestrian facilities in Indonesia's urban areas is the lack of fulfillment of pedestrian needs, both in terms of quality and quantity. The development of pedestrian facilities in Indonesia has not become a priority comparable to the development of facilities for other modes of transportation. The lack of public understanding of pedestrian path facilities indicates the need for attention from the government in fulfilling the functional needs of pedestrian paths. Because of that it is important to understand the public's perception of the need for pedestrian facilities on Jalan Veteran Lamongan. Distribute questionnaires to the community and then carry out validity and reliability tests so as to produce public perceptions of pedestrian lane facilities on veteran roads, namely pedestrian paths, which need additional attention for facilities and infrastructure. 34% of respondents said there were many deficiencies in the quality of the sidewalks, then 31% said they lacked the quality of facilities for the disabled, then 33% of respondents said they lacked the quality of accessibility, then 31% of respondents felt they lacked the level of completeness of facilities, then 33% respondents said they lacked the level of safety, then as many as 36% of respondents felt they lacked the level of security, and finally 37% of respondents felt they lacked the level of satisfaction.

Asphalt Concrete Wearing Course (AC-WC) is a flexible highway pavement, where this pavement is a combination of: Asphalt, fine aggregate coarse aggregate, and (filler). In this study, the replacement of Portland cement filler was carried out as an experiment with alternative materials, namely rice husk ash and wood sawdust. Where in this research mixture the percentage of cement filler is 2% replaced using 2% SP ash, 2% SK ash, 1% SP ash: 1% SK ash, in terms of Marshall properties In accordance with the standard requirements of General Specifications 2010 (revision 3) Section 6.3 Hot bituminous mix. From the Marshall test results, the highest stability value was 938.71 kg and a flow value of 2.83 mm by substituting 2% SP ash filler, where the resistance was better than the standard 2% cement filler mixture with a stability value of only 889.68 kg . The VIM value obtained was 3.57%, although it met the standard, the VIM value indicated that the 2% rice husk ash filler substitution mixture was not watertight. It can be seen that the high VMA value of 23.30% indicates the large number of cavities in the AC-WC mixture. Where the greater the percentage of VIM and VMA, the lower the adhesiveness of the asphalt mixture by substituting Cement filler using SP ash, as evidenced by the VFA value of only 52.41% which does not meet standard specifications, because the voids created will be filled with air or water. Replacement of 2% SP ash filler obtained a Marshall Quotient value of 333.70 kg/mm which met the specification standard, namely Min 250 kg/mm but higher than the normal 2% cement filler mixture which was only 258.23 kg/mm.

Using alternative materials in construction, such as eggshell fly ash (CT) and rice husk (SP), is increasingly important in reducing environmental impact. This research explores the influence of the proportion of CT and SP mixtures on concrete compressive strength and cracking. Both agricultural waste materials can potentially affect concrete characteristics, including binding ability, strength, and crack resistance. Testing was conducted using ASTM C standards for material and Indonesian national standards for concrete compressive strength and cracking. Variations in composition, 0% (A), 3% CT-5% SP (B), 5% CT-10% SP (C), and 7% CT-15% SP (D) by weight of cement, were performed on a total of 24 specimens. The results show that Concrete C had the highest compressive strength (212.2 kg/cm²), while Concrete D had the lowest compressive strength (165.56 kg/cm²). At 7 days, the highest cracking occurred in Concrete D (28.7 cm), and the lowest in Concrete C (22.3 cm). At 28 days, Concrete A had the highest cracking (26 cm), while Concrete C had the lowest (18.3 cm). This study provides valuable insights for the construction industry to utilize eggshell fly ash and rice husk in improving concrete performance and promoting sustainable development.
