Abstract

The function of Primary arterial street is to serve as road users to connect to the national activity center and for regional activity, which is long-distance travel. On that road, there are so many roads damaged, damaged due to heavy vehicle loads and some high frequencies. The study aims to identify the type of damage and to help in how the maintenance management of this street through system will be managed and systematically stored in the form of databases. The research used Bina Marga methods, assessments of road conditions refer to the Organizing of Urban Road Maintenance Programs issued by the Directorate General of Bina Marga. The survey was divided into 20 segments per 100 meters, the data were obtained from field surveys, with damage data and field photos, and then input data of the street table that use the file formats in ArcGIS software, and later data can be further analyzed. Research shows that the dominant damage happens in grains and patching. Research results on the road of Soekarno-Hatta KM 8-10 have a pretty low rate of damage, shown by the maintenance priorities listed in a regular maintenance program, which means maintenance or repair simply top layer without repairing road structures

Abstract

SPBU KM. 38 is a gas station that distributes subsidized fuel, one of which is diesel. The scarcity and limited availability of fuel, especially diesel fuel, causes many heavy vehicles to queue and cause the traffic loading. This loading has an impact on the performance of the road network around the location, that is Jl. Soekarno Hatta KM. 38. The traffic load due to the diesel queue has a direct impact on the performance of the road network around the location. This study aims to evaluate the service performance of the queuing system and facilities for refueling diesel fuel at SPBU KM. 38 and Knowing the performance of the Jl. Soekarno Hatta KM. 38 based on the MKJI 1997, and the effect of queues for SPBU KM. 38 on road performance. This study uses the Quantitative Research method. Where Quantitative Research has a detailed and measurable characteristic. Based on the results of the study, the highest average time spent waiting in the queue to be served was 0.167 hours≈10.02 minutes. This shows that the facility for refueling diesel fuel is not optimal because the standard time for refueling diesel fuel is 2.5 minutes. The value of the road capacity that has narrowed is 3,072 smp/hour, and the normal road capacity is 3,516 smp/hour. The highest level of service on roads with narrowing occurs on Sundays with service level is D, while on normal roads the highest service levels occur on Mondays and Sundays with service level is C. The queue that occurs causes an increase in the level of service. Therefor it can be concluded that the queue affects the level of service at the research location.

Abstract

Abstrak   Penelitian ini bertujuan untuk menganalisis pengaruh substitusi abu pelepah pisang terhadap kuat tekan beton pada umur 14 dan 28 hari. Abu pelepah pisang diperoleh melalui proses pembakaran pada suhu ±600°C, kemudian disaring hingga lolos saringan 0,075 mm. Variasi substitusi terhadap berat semen yang digunakan adalah 0%, 2,5%, 5%, 7,5%, dan 10%. Pengujian kuat tekan dilakukan pada benda uji silinder berukuran 150×300 mm sesuai SNI 1974:2011. Hasil penelitian menunjukkan bahwa penambahan abu pelepah pisang berpengaruh terhadap peningkatan kuat tekan beton. Nilai kuat tekan tertinggi diperoleh pada variasi 7,5% dengan kuat tekan sebesar 12,87 MPa pada umur 14 hari dan 15,02 MPa pada umur 28 hari, meningkat sebesar 17% dibanding beton normal. Namun, pada kadar 10% terjadi penurunan kuat tekan hingga 13,09 MPa. Hasil ini menunjukkan bahwa abu pelepah pisang dapat dimanfaatkan sebagai bahan substitusi semen hingga kadar optimum 7,5% tanpa menurunkan kekuatan beton. Penelitian ini mendukung konsep green building melalui pemanfaatan limbah biomassa lokal sebagai material ramah lingkungan.   Kata kunci: Abu pelepah pisang, substitusi semen, kuat tekan beton, beton ramah lingkungan, green building     Abstract   This study aims to analyze the effect of banana pseudostem ash substitution on the compressive strength of concrete at the ages of 14 and 28 days. The banana pseudostem ash was produced by burning the dried pseudostems at a temperature of approximately 600°C and sieving the resulting ash through a 0.075 mm sieve. The substitution levels of cement by weight were 0%, 2.5%, 5%, 7.5%, and 10%. Compressive strength tests were conducted on cylindrical specimens measuring 150×300 mm in accordance with SNI 1974:2011. The results show that the addition of banana pseudostem ash positively affects the compressive strength of concrete. The highest compressive strength was obtained at a 7.5% substitution level, with values of 12.87 MPa at 14 days and 15.02 MPa at 28 days, representing a 17% increase compared to normal concrete. However, at a 10% substitution level, the compressive strength decreased to 13.09 MPa. These findings indicate that banana pseudostem ash can be effectively utilized as a partial cement replacement up to an optimum level of 7.5% without reducing concrete strength. This research supports the green building concept through the utilization of local biomass waste as an environmentally friendly construction material.   Keywords: Pseudostem ash, cement substitution, compressive strength, eco-friendly concrete, green building
