Abstract

Clay soils characterized as soft soils often cause problems due to their weak bearing capacity and long consolidation time. Rice husk ash, which is one of the wastes derived from burning rice stalks and leaves, can be used to increase the bearing capacity of the soil. This research analyzed the effect of adding rice husk ash as a mixture in soil stabilization at 0%, 8%, 12% and 16%. Based on laboratory testing using soil samples from Jalan Merdeka RT 14 Bawah Alai Balai Agung Village, Sekayu District, South Sumatra. Bawah Alai, Balai Agung Urban Village, Sekayu District, South Sumatra. It is concluded that the effect of rice husk ash makes the shear angle of the soil smaller or reduced. The highest shear angle was obtained when the addition of 8% rice husk ash amounted to 9.373 kPa. When adding 12% and 16% rice husk ash, the shear angle of the soil decreased to 4.651 kPa and 4.288 kPa, respectively. The addition of variation in rice husk ash affects the cohesion value (c), overall it can be said that the value of soil shear angle increases with the lower variation in the soil mixture.

Abstract

Sedimentation is one of the main factors affecting the hydraulic capacity and performance of urban rivers. This study aims to analyze flow capacity and the impact of sedimentation on a river’s ability to convey flow optimally. Flow capacity analysis was conducted using the Frijlink method with a rectangular channel cross-section approach, while sediment distribution and accumulation were analyzed through hydraulic modeling using HEC-RAS software. The analysis results show that the river’s flow capacity is 3,381 m3/s. An evaluation of bed sedimentation indicates that observation point 3 has the highest sedimentation rate, with a sediment discharge of 2.85 × 10-8 m3/s/m and a sedimentation volume of 5.78 × 10-4 m3/s. The HEC-RAS modeling results show that the river’s capacity is unable to accommodate the flow rate optimally under high rainfall conditions, thus potentially causing local flooding or waterlogging.

Abstract

ABSTRAKLapis aus merupakan lapisan perkerasan jalan yang rentan mengalami kerusakan seperti retak (cracking) dan deformasi permanen, sehingga diperlukan inovasi pada campuran material. Penelitian ini bertujuan menentukan kadar aspal optimum (KAO) menggunakan aspal penetrasi 60/70 dengan penambahan crumb rubber (2,5%, 3%, 3,5%) sebagai aditif serta abu tempurung kelapa sebagai filler. Pengujian Marshall digunakan untuk mengevaluasi karakteristik campuran. Hasil penelitian menunjukkan penambahan crumb rubber dan filler berpengaruh signifikan terhadap sifat campuran. Pada kadar 3,5% crumb rubber diperoleh kepadatan 2,514 t/m³ dan VFA 78,038%, sedangkan stabilitas tertinggi 1.572,082 kg dan flow 4,490 mm terjadi pada kadar 3%. Nilai kepadatan dan VFA tinggi menunjukkan rongga udara kecil yang berpotensi menimbulkan bleeding dan rutting. Sebaliknya, kombinasi crumb rubber dan abu tempurung kelapa menurunkan kepadatan serta stabilitas, tetapi meningkatkan VIM 4,998% dan VMA 18,051%, sehingga campuran lebih fleksibel namun berisiko stripping.Kata kunci: crumb rubber, abu tempurung kelapa, ac-wc, marshall test, aditif ABSTRACTThe surface layer is a layer of road pavement that is prone to damage such as cracking and permanent deformation, necessitating innovation in material mixtures. This study aims to determine the optimum asphalt content (OAC) using 60/70 penetration asphalt with the addition of crumb rubber (2.5%, 3%, 3.5%) as an additive and coconut shell ash as a filler. Marshall testing was used to evaluate the characteristics of the mixture. The results show that the addition of crumb rubber and filler significantly affects the properties of the mixture. At a crumb rubber content of 3.5%, a density of 2.514 t/m³ and VFA of 78.038% were obtained, while the highest stability of 1,572.082 kg and flow of 4.490 mm occurred at a content of 3%. The high density and VFA values indicate small air voids that could potentially lead to bleeding and rutting. Conversely, the combination of crumb rubber and coconut shell ash reduces density and stability but increases VIM to 4.998% and VMA 18,051%, making the mixture more flexible but at risk of stripping.Keywords: crumb, rubber, coconut shell ash, ac-wc, marshall test, aditif

Abstract

One of the largest cities, because it is the center of social and economic activities, is Palembang City. The area of ​​Palembang City is around 400.61 km², consisting of 16 sub-districts and 107 villages. In this area, heavy rain has occurred which has caused flooding in this area, especially on Jalan Pipa Raja, Palembang City. One of the causes of flooding in Palembang is due to low land conditions and high tides of the Musi River. In the role of flood control, the lack of public awareness in maintaining the drainage system also worsens waterlogging. Flood control requires extensive and specific engineering knowledge. The structural method used in this study is the retention pond method. The retention pond on Jalan Pipa Jaya in Kemuning District has a capacity of around 328.8 m3/hour. Data for this study were obtained from literature studies, primary data, and secondary data. The results of the study that have been carried out indicate that in modeling using HEC-HMS, it is known that the Pipa Jaya retention pond can accommodate a peak inlet discharge of 161.3 m3/s, with a decrease to 29.7 m3/s.

Abstract

Geopolymer concrete is an environmentally friendly alternative to conventional concrete because it has the potential to reduce carbon emissions. Rice husk ash, an agricultural waste, serves as a source of silica and alumina in the geopolymerization process. This study aims to determine the compressive strength value of geopolymer concrete in each variation and the use of alkali activator ratios between Na2SiO3 and NaOH with ratios of 1:2, 2:2, and 3:2. In the study of the compressive strength characteristics of engineering concrete, the experimental method was used. Based on the study of the compressive strength characteristics of geopolymer concrete made from rice husk ash, normal concrete at the age of 28 days has a compressive strength of 368 kg/cm2, while in the 1st geopolymer concrete at the age of 28 days, a compressive strength of 349 kg/cm2 is obtained. This shows that the compressive strength of the 1st geopolymer concrete has decreased by 5% from normal concrete, in the 2nd geopolymer concrete at the age of 28 days, a compressive strength value of 475 kg/cm2 was obtained, which means that the compressive strength of the 2nd geopolymer concrete has increased by 29% from the compressive strength of normal concrete. This study identified the optimal compressive strength of geopolymer concrete, specifically noting that the second geopolymer concrete reached a value of 475 kg/cm².

Abstract

Environmental safety and order are important aspects of creating a harmonious and prosperous community life. Environmental Security Posts (Pos Kamling) play an important role as a community-based security system in maintaining order and preventing crime. However, residents in RT. 17, Sukamulya Village, Sematang Borang District, Palembang City are facing the problem of the increasing number of vehicle theft cases parked in their home yards. Therefore, this community service activity is carried out with the aim of designing and building a neighborhood watch post as a solution to improve environmental security. The methods used include field surveys, direct observation, and interviews with RT officials and local residents to collect relevant data and information. The results of this service include the preparation of Pos Kamling planning documents, including the calculation of the Budget Plan (RAB), as well as the physical construction of the post until it is ready for use. Beside being a security monitoring center, the neighborhood watch post also serves as a means of social interaction that can strengthen relationships between residents. A Pos Kamling management unit was established after the activity to carry out the patrol SOP, supply the duty schedule, oversee the fast reporting channel, and accept the transfer of DED, RAB, and SOP papers as operational instructions.
