Parking problems are very important to study in more depth. If the need for parking space is not sufficient, then the vehicle will park on the roadside (on-street parking), which causes congestion. Traffic jams due to parking on the road shoulder also occurred on Sultan Syahrir Street, South Surakarta Legi Market. This study aims to analyze parking capacity, road saturation degree, parking patterns, and parking revenue. In this study, the method used is quantitative data processing by collecting primary and secondary data by analyzing parking space requirements, calculating parking space capacity, determining parking patterns, and parking income. Static capacity for 2-wheeled vehicles is 96 SRP, and for 4-wheeled vehicles, it is 74 SRP with a road capacity of 3,039.96 pcu/hour. The saturation degree value of Sultan Syahrir Street on Saturday was 0.311 pcu/hour, and on Tuesday it was 0.297 pcu/hour. Based on the table of service levels for Sultan Syahrir Street, it is included in service level B, which means stable flow, limited speed, and volume suitable for roads outside the city. With a 45-degree and parallel parking angle solution, the average revenue for 2 and 4-wheeled vehicles is Rp. 934,000 - Rp. 1,567,500. Suggestions for the Surakarta City regional government to study some problems that exist on Sultan Syahrir Street, such as determining parking angles and road markings, to overcome congestion or divert to alternative routes Road performance and service levels need to be improved so that the arrangement of parking spaces on Sulta Syahrir Street is better.

Pondok Reservoir is one of the small reservoirs in the Bengawan Solo River Basin (DAS) which has an area of 3,450 ha and can hold as much as 29 million m3 of water. Over time, weir operation activities must be in line with weir maintenance activities. In this regard, it is necessary to evaluate the performance of irrigation areas. The method used in this study was observation and direct observation in the field by tracing the irrigation network of the D.I Pondok Reservoir and conducting secondary data analysis. The results of this study indicate that the total number of physical infrastructure assets is 139 consisting of 62 control buildings and 87 auxiliary buildings. The condition of the physical infrastructure of the Pondok D.I Reservoir for the carrier channel is 70.6% in good condition and 29.4% in a slightly damaged state, for regulatory buildings 70% is in good condition, 8.3% is in a slightly damaged condition, and 21.7% is in good condition. severely damaged condition, for supporting buildings 69.6% in good condition, 19% in slightly damaged condition, and 11.4% in severely damaged condition, for drainage and buildings in good condition, and for access/inspection roads 94% in good condition well and the remaining 6% is in slightly damaged condition. Physical infrastructure performance in the Pondok D.I Reservoir was obtained at 68.84% of 100%, meaning that this performance is included in the less criteria and needs attention

Quality is a key factor that brings success in construction, growth, and improvement. Quality is a basic factor in consumer decisions that shapes determining the desired products and services. One of the factors that influences product quality is the quality control method, which will be able to improve the quality of the company's output by reducing the level of defects. The Quality Control Circle (QCC) method is a method that can be used to reduce defects in a relatively short time, can be carried out, and is easily implemented in small teams so that it does not involve all personnel in an organization. Apart from this, QCC can also save costs by improving quality because of its small organizational structure. To be able to survive in the midst of intense competition and the growth of the construction industry, companies must have advantages that other companies do not have. The determining factor of competitiveness is to improve quality. This effort was made by the company by making continuous improvements with the aim of reducing the number of product defects. The author used the quality control cylinder method to reduce defects in structural column work at Gadjah Mada University's Smart Green and Learning Center (SGLC) building project. The focus was on analyzing concrete structural columns to reduce defects and achieve a cost efficiency of 82.87%. Improvements were made to elements of the structural column work method, reducing 80% of defects. The QCC method was used to prevent defects from recurring in the product.

The increase in population Colomadu District which has increased well the development of human activities have encouraged the physical the city development. Development of health facilities in area needs to be carried out in effort support programs to improve public health status. So a 5 storey hospital building was designed in Colomadu District. This structural planning aims to plan building structure that is safe, comfortable, and efficient and know the required budget plan. The results obtained are roof slabs 10 cm thick with x, y reinforcement Ø12 – 200 mm, floor slabs 12 cm thick with x, y reinforcement Ø12 – 150 mm, main beam B1 dimension 300 x 500 mm top reinforcement 2 D19 bottom reinforcement 3 D19 reinforcement shear bar Ø10 – 150 mm, main beam B2 dimension 300 x 450 mm top reinforcement 2 D19 bottom reinforcement 3 D19 shear reinforcement Ø10 – 150 mm, joist beam BA dimension 200 x 300 mm top reinforcement 3 D10 bottom reinforcement 3 D10 shear reinforcement Ø10 – 150 mm, sloof beam TB dimension 250 x 400 mm top reinforcement 3 D16 bottom reinforcement 6 D16 shear reinforcement Ø10 – 150 mm, column K1 dimension 600 x 600 mm longitudinal reinforcement 16 D19 and shear reinforcement Ø10 – 150 mm, is column K2 dimensions 500 x 500 mm longitudinal reinforcement 16 D19 and shear reinforcement Ø10 – 200 mm, bore pile foundation reinforcement dimensions 60 cm depth 8 m with longitudinal reinforcement 10 D22 spiral reinforcement Ø16 – 200 mm, and budget plan with total budget Rp. 13.280.305.901,00.

SOI LEE CHIA; MOHD ZAMRI JAMALUDIN; ABDUL MUIZ ABD RAJAK HAMIM — Tue, 19 Dec 2023 07:57:15 +0700

Asphalt is a mixture of aggregates, bitumen, quarry dust, and cement. As an addition in hot mix asphalt mixtures, recycled tire rubber known as "crumb rubber" is regarded as an environmentally friendly building practice. The laboratory hot mix asphalt design tests were conducted according to Marshall method procedure. In this study, three different crumb rubber contents (10%, 15%, and 20% by weight of bitumen), and three different bitumen contents (4%, 5%, and 6%) with a penetration grade 60/70 were investigated. The Marshall stability value and durability properties were taken into account in a comparison study between the standard and modified asphalt concrete mixtures. The strength and performance of asphalt mixtures tended to improve with the addition of crumb rubber. As some of the test results were within the acceptable range, the findings indicated that crumb rubber is advised for use as an addition in asphalt mixtures. Besides, the durability of asphalt mixtures also needed to be concerned.
