Abstract

Pangeran Antasari Street plays an important role in serving and passing large number of traf - fics. The traffics, coupled with roadside barriers, cause delays in travel time. The purpose of this study is to analyze the performance of roads that is the level of service as well as the increase in travel costs due to delays. The assessment of the performance of the road section was carried out based on free flow traffics, which is the condition of the traffic flow without experi - encing delays and roadside obstacles. Performance values were obtained through a linear approach between the volume and speed of the vehicle using the Greenshield Model. Calculation of Vehicle Operating Costs (Biaya Operasional Kendaraan or BOK) of light vehicles and heavy vehicles were using a model developed by the Indonesian Research Affiliation Institute of the Bandung Institute of Technology (Lembaga Afiliasi Penelitian Indonesia Institut Teknologi Bandung or LAPI - ITB). Whereas the motorcycle BOK were useing the Road Traffic Services (Di - nas Lalu Lintas Angkutan Jalan or DLLAJ) method. The value of travel time was calculated based on the approach using the data of the City of Bandar Lampung's per capita income di - vided by the average number of working hours per year. The results showed that the service level of the Pangeran Antasari road segment was V / C > 0.8. This means that the road has a service level of D, which is near congested. The cost of congestion caused by traffic delays for the direction of Pangeran Antasari - Gajah Mada is Rp. 625.863.840/year, while for the direc - tion of Gajah Mada - Antasari is Rp. 845.009.609/year.

Abstract

The construction process frequently necessitates the demolition of existing structures, resulting in substantialconstruction waste. A significant portion of this waste comprises demolition debris, particularly from concrete buildingmaterials. This research aims to develop standard concrete by partially substituting conventional coarse and fineaggregates with concrete waste materials. The substitutions involved replacing 25% and 50% of sand and gravel,respectively, by weight, using a K300 concrete mix design. Adopting the SNI 03-2834-2000 method, the mix design for 1cubic meter of concrete comprised cement (528 kg), sand (776.16 kg), gravel (807.04 kg), and water (205 kg). Theresults indicated an average sample weight reduction, with the first sample at 12.91 kg, the second at 12.79 kg, and thethird at 12.77 kg. This weight decrease suggests that using waste as a partial aggregate substitute impacts concretedensity. Compressive strength tests revealed a reduction of 5.98% in the concrete containing a 25% waste mixture, withaverage compressive strength declining from 307.22 kg/cm² to 288.94 kg/cm². A more pronounced reduction occurred inthe 50% waste mixture, where compressive strength decreased by 15.70% (from 307.22 kg/cm² to 259.06 kg/cm²). Thistrend aligns with the understanding that higher waste content correlates with greater mechanical strength reduction, likelydue to the differing physical properties of waste materials, such as lower density, which impact overall concreteperformance, particularly in compressive strength.

Abstract

ABSTRACT The increasing number of new student admissions for the 2023/2024 academic year at the Lampung State Polytechnic has an impact for increasing the number of vehicles that will go through the road or park their vehicles in lecture building. The use of the Joint Lecture Building facilities will be used in early 2023 cannot be separate from the available vehicle parking facilities. Reduce public transportation, which causes students, lecturers, Educational Laboratory Institution, technicians, and other employees switching to use private vehicles. The purpose of this study was to find out how much parking capacity is available for users of the Joint Lecture Building. Methods use by conduct on-site surveys, conducting measurements, calculation of PSU for motorcycles and passenger cars. Based on the survey results, three parking locations were obtained. With an area of Location 1 of 1196,184 m2, Location 2 of 3020,028 m2, and an additional Location 3 of 1319,628 m2. From the land area, then calculate the PSU for Passenger Cars 2.5 m x 5 m and PSU for Motorcycles 0.75m x 2 m. The width of the Alley Lane for 1-way Passenger Cars is at least 6 m and 2-way is at least 8 meters, while for motorcycles is 1.6 meters. Results obtained for Location 1 resulted in 57 PSU for Motorcycles and 27 PSU for Passenger Cars. Location 2 produces 672 PSU for Motorcycles and 47 PSU for Passenger Cars. An additional location 3 resulted in 540 PSU Motorcycles. Thus, the total for Motorcycles is 1244 PSU and Passenger Cars is 74 PSU, for a total of 1343 PSU.

Abstract

The spatial distribution of campus facilities is a critical determinant of the efficiency of spatial planning in higher education institutions. This study examines the spatial distribution pattern of campus public facilities using the Average Nearest Neighbor (ANN) method within a Geographic Information System (GIS) framework. The study was conducted at Lampung State Polytechnic using centroid point data of buildings with a total study area of 202,943.98 m². The analysis yielded a Nearest Neighbor Ratio (NNR) of 0.884, indicating a tendency toward spatial clustering. However, this tendency was not statistically significant at the 95% confidence level (Z-score = ?1.567; p = 0.117 > 0.05), and the building distribution is therefore classified as random. Inter-building distance analysis revealed that the observed mean distance (28.16 m) is approximately 11.6% shorter than the expected distance under a random distribution (31.85 m), suggesting that contextual factors—including land constraints, functional connectivity requirements, incremental development patterns, and utility network efficiency—have collectively influenced building placement. The predominantly random distribution pattern reflects a process of adaptive spatial development conducted without reference to a comprehensive spatial master plan, which may give rise to circulation inefficiencies, utility integration challenges, and suboptimal open space utilization. This study demonstrates that GIS-based spatial statistical analysis affords an objective, quantitative evaluation of campus spatial planning and can serve as a scientific basis for the formulation of more structured, data-driven facility development policies.
