Agatha Adhitya Buton — 2026-06-29

ABSTRACT

As one of the modes of land transportation, road transportation in Indonesia dominates and is the most used transportation for transporting goods and services. Highways are an important component in the dynamics of development to grow and improve the development of national development in advancing general welfare as referred to in the Preamble to the 1945 Constitution of the Republic of Indonesia (Noor Mahmudah, 2019). In Indonesia, highway construction continues to be improved, both repair and maintenance efforts, as well as the construction of new roads. This study aims to determine the type of heavy equipment used and calculate the efficiency of heavy equipment productivity in the pile cap work of the Mranggen-Godong flyover construction project. The research method used is descriptive qualitative to explain the results of heavy equipment calculations based on calculation data collected through documentation techniques and literature reviews. Based on the research results, the productivity results of the heavy equipment used in the pile cap and abutment work for the Mranggen-Godong flyover construction project were obtained, namely excavators of 739.615 m3/hour, dump trucks 96.149 m3/hour, bar cutters 8,789.66 kg/hour, bar benders 6,665.65 kg/hour, and concrete mixer trucks 24.001 m3/hour.

EVALUASI PARKIR KENDARAAN (ON THE STREET PARKING) PADA JALAN DR. RADJIMAN KOTA SURAKARTA

Maulana Wakhid Riffani — 2026-06-29

The development of economic activities and the increasing number of motor vehicles in Surakarta City have led to a high demand for parking space, particularly in commercial center areas. One of the emerging problems is the use of road shoulders as parking areas (on-street parking), which has the potential to reduce road performance. Dr. Radjiman Street in Surakarta City is one of the road segments with high parking activity due to its location in a commercial district, frequently causing traffic congestion. This study aims to identify the existing parking conditions, analyze the characteristics of on-street parking, and determine the most appropriate solutions to meet parking demand on Dr. Radjiman Street, Surakarta City. The research method employed was a field survey, with primary data collection including vehicle entry and exit data, parking duration, parking volume, parking accumulation, parking index, parking turnover, and road geometric data. The survey was conducted on Saturdays and Sundays to represent days with high parking activity. The results indicate that the existing parking capacity is insufficient to accommodate four-wheeled vehicles, as reflected by parking index values exceeding 100% during certain hours. This condition leads to excessive use of the roadway, reducing the effective road width and disrupting traffic flow. Based on the analysis, a reorganization of parking patterns with appropriate parking angles, along with the optimization of off-street parking facilities, is required as a solution to reduce on-street parking. It is expected that the findings of this study can serve as a reference for relevant stakeholders in managing and organizing parking facilities to improve traffic performance on Dr. Radjiman Street, Surakarta City.

Infrastructure growth is in line with the growth of human resources, the more the population will require more infrastructure facilities. Construction infrastructure in Indonesia is currently starting to focus on development that leads to the use of structures with lightweight materials and has high resistance. This is inseparable from Indonesia's geographical location which is on the Pacific Ring of Fire which makes Indonesia prone to earthquakes. Therefore, it is necessary to conduct research on lightweight concrete that can overcome these potential hazards. This study used lightweight brick powder, bagasse ash and fly ash in replacing concrete materials. The method used is experimental by creating variations of lightweight concrete by adding lightweight brick powder amounting to 70% of the volume of fine aggregate. The results of the optimal content of bagasse ash use are 10% and fly ash 15% of the total cementitious. Testing of lightweight concrete variations was carried out on concrete aged 7, 14, 21 and 28 days. On lightweight concrete aged 28 days, a comparison was made with normal concrete. The results of the test weight of lightweight concrete aged 7, 14, 21 and 28 were 2.89 kg; 2.83 kg; respectively. 2.80 kg and 2.79 kg. The results of the lightweight concrete compressive strength test at the age of 7, 14, 21 and 28 were 16.54 MPa, 22.27 MPa, 25.25 MPa and 26.74 MPa, respectively. The resulting density ratio was 1743 kg/m3 for lightweight concrete and 2283 kg/m3 for normal concrete. The resulting compressive strength comparison from the creation of lightweight concrete at the age of 28 days from 3 test specimen samples was 26.74 MPa, 27.37 MPa and 26.10 MPa, respectively, while in 3 normal concrete samples the values were 24.19 MPa, 24.83 MPa and 26.10 MPa.

ANALISIS STABILITAS LERENG DENGAN PERKUATAN BRONJONG MENGGUNAKAN SOFTWARE SLOPE/W ANALYSIS 2018 (KM 15+700)

The Grompol River is one of the rivers that crosses the Sragen area. The area around the lower reaches of the Grompol River in Sragen is vulnerable to slope stability problems due to erosion and land subsidence. In overcoming this problem, strengthening gabions is one solution that may be effective. For this reason, it is necessary to analyze slope stability accurately and effectively using software calculations and manual calculations. The software used for the analysis is Slope/W Analysis 2018. The research was carried out by testing low, medium and high tide water levels. The test results with these 12 conditions show the safety of natural slopes given earthquake loads at low water conditions. Safety Factor = 1.511; Medium water conditions Safety Factor = 1.617; High tide conditions Safety Factor = 1.746; Reinforced slopes are subjected to earthquake loads at low water conditions. Safety Factor = 1.910; Medium water conditions Safety Factor = 2.169; High tide conditions Safety Factor = 2.589; Natural slopes are subjected to earthquake loads and evenloads with low tide conditions. Safety Factor= 1.369; Medium water conditions Safety Factor = 1.455; High tide conditions Safety Factor = 1.690; Slopes with reinforcement and even load are given earthquake loads under low water conditions. Safety Factor = 1.653; Medium water conditions Safety Factor = 1.844; High tide conditions Safety Factor = 2.138
