MITIGASI BENCANA TANAH LONGSOR DI DESA TANAH ABANG UTARA KECAMATAN TANAH ABANG KABUPATEN PALI
Landslides are natural disasters caused by slope instability resulting from geomorphological, hydrological, and human activity factors. This phenomenon can occur suddenly or gradually, causing significant impacts on infrastructure, safety, and community access. In North Tanah Abang Village, Tanah Abang District, PALI Regency, the landslide risk is quite high due to steep topography, erosion of the Lematang River, and human activities such as deforestation and sand mining. Risk analysis through parameters such as geology, topography, rainfall, and land use indicates a moderate to high danger level in this area. Effective mitigation efforts include structural approaches like terracing and retaining walls, as well as non-structural approaches such as reforestation, community education, and land use regulation. The implementation of early warning systems is also a crucial step in reducing the impacts and losses caused by landslides. Through these measures, it is expected that the landslide disaster risk in this region can be minimized and community preparedness improved.

STUDI PENGGUNAAN AGREGAT HALUS PASIR DAN AGREGAT KERIKIL ALAM SUNGAI BATANGHARI TERHADAP KUAT TEKAN BETON
Abstract View: 194 PDF Download: 161Concrete is a widely used construction material due to its high strength and durability. The quality of concrete is greatly influenced by the characteristics of the aggregates that make up 60–70% of the concrete volume. This study aims to analyze the effect of fine sand aggregate and coarse natural gravel aggregate from the Batanghari River on the compressive strength of concrete. Three sample variations were used, namely: AA (Mendapo Quarry and Kasang Quarry aggregates), BB (RBE Quarry and Sengeti Quarry aggregates), and AABB (a combination of AA + BB). The test specimens were cylindrical in shape, measuring 15×30 cm with a design quality of 20 MPa. Compressive strength testing was carried out at the ages of 7, 14, and 28 days according to SNI 1974:2011. The test results at 7 days of age were 5.436 MPa for AA samples, 5.067 MPa for BB samples, 5.879 MPa for AABB samples, at 14 days of age 16.080 MPa for AA samples, 13.389 MPa for BB samples, 14.829 MPa for AABB samples and at 28 days of age 20.907 MPa for AA samples, 17.403 MPa for BB samples and 22.036 MPa for AABB samples which produced the highest compressive strength. The combination of aggregates provides better gradation, low porosity, and higher density. The natural aggregates of Batanghari River are proven to be suitable for use in medium quality concrete.

Abstract View: 172 PDF Download: 140Peat soil is a soil that physically and technically does not meet the requirements and conditions in construction work. This study aims to evaluate the improvement of soil carrying capacity using cement stabilization methods, focusing on the value of California Bearing Ratio (CBR) unsoaked. Tests are carried out in laboratories to analyze the physical and mechanical properties of the soil. This research is intended to address the significant subsidence problem that can occur in road construction built on peat soil. The results showed that the CBR value of native soil was 3.00%. After the addition of 4% cement, the CBR value increases to 3.25%. At the addition of 6% cement, the CBR value fell to 2.50%, while at the addition of 8% cement, the CBR value reached 4.17%. It can be concluded that the greatest increase in the value of CBR occurs in the addition of 8% of cement. Thus, soil stabilization methods using cement mixtures can increase the CBR value of peat soils.

Abstract View: 200 PDF Download: 127This study aims to analyze the impact of side friction on traffic performance along MP Mangkunegara Street, Palembang City, using the PKJI 2023 method and the Greenshields model. Observed side friction factors include parked/stopped vehicles, pedestrians, entering/exiting vehicles, and street vendors, with a very high intensity reaching 811.8 events/hour on Saturday and 890.4 events/hour on Tuesday. These conditions contribute to a significant reduction in free-flow speed and road capacity. Based on the Greenshields model analysis, the free-flow speed (Vf) decreased significantly from 38.833 km/h to 26.028 km/h, while the jam density (Dj) increased from 69.90 smp/km to 158.128 smp/km. Although the maximum flow (Qmax) increased due to rising density, the speed at maximum capacity declined. The peak-hour degree of saturation ranged from 0.44 to 0.78, indicating a level of service between B and D.
