Abstract

Jalan merupakan prasarana infrastruktur dasar yang dibutuhkan manusia untuk melakukan pergerakan dari suatu lokasi ke lokasi lainya dalam rangka pemenuhan kebutuhan. Pada dasarnya jalan akan mengalami penurunan kualitas strukturalnya sesuai bertambahnya umur jalan, apalagi jika dilalui oleh kendaraan dengan muatan berat dan cenderung melebihi ketentuan. Penelitian ini bertujuan untuk menghitung penurunan umur rencana perkerasan jalan. Penelitian ini dilakukan dengan cara  membandingkan antara total lintasan beban rencana dengan total lintasan beban aktual (dengan dasar asumsi beban rencana sebagai beban kendaraan tidak melanggar dan beban aktual sebagai beban kendaraan melanggar) Tempat yang diteliti adalah suatu ruas jalan yang berada dijalan Daerah Desa Karang Tunggal Kecamatan Tenggarong Seberang Kabupaten Kutai Karta Negara Provinsi Kalimantan Timur. Tipe jalan yang diamati adalah Jalan kolektor IIIB. Hasil analisis yang telah dilakukan, penyebab utama kerusakan jalan adalah dari beban kendaraan yang melebihi ketentuan overload. kerusakan pada kontruksi jalan dapat disebabkan oleh beberapa faktor berikut hasil kesimpulan pada kendaraan ringan dengan JBI 2 ton menjadi 2,622 ton. Pada kendaraan truk dengan JBI 8 ton menjadi 8,513 ton. Karena adanya penyimpangan beban tersebut mengakibatkan pengurangan umur rencana dari 5 tahun menjadi 3,939 tahun.

Abstract

Distribution systems or infrastructure, including access to farm roads, have a strategic role in supporting the efficiency of harvest transportation. Adequate infrastructure will reduce distribution costs, shorten travel time and maintain the quality of the harvest. Farm transportation costs in East Kalimantan are still very high due to inadequate farm roads, this affects the competitiveness of local harvests against other areas which tend to be better than East Kalimantan Province. This study is expected to identify factors that contribute to the high cost of transporting rice harvests in East Kalimantan. In addition, this study aims to provide strategic recommendations in efforts to improve distribution efficiency and the competitiveness of local products.Sistem atau infrastruktur distribusi, termasuk akses jalan usaha tani memiliki peran strategis dalam menunjang efisiensi transportasi hasil panen. Infrastruktur yang memadai akan mengurangi biaya distribusi, mempersingkat waktu tempuh dan menjaga kualitas hasil panen. Ongkos angkut usaha tani di Kalimantan Timur masih sangat tinggi dikarenakan jalan usaha tani yang tidak memadai, hal ini mempengaruhi daya saing hasil panen lokal terhadap daerah lain yang cenderung lebih baik dibanding Provinsi Kalimantan Timur. Penelitian ini diharapkan dapat mengidentifikasi faktor yang berkontribusi terhadap tingginya biaya angkut hasil panen padi sawah di Kalimantan Timur. Selain itu penelitian ini bertujuan untuk memberikan rekomendasi strategis dalam upaya meningkatkan efisiensi distribusi dan daya saing produk lokal.

Abstract

Traffic analysis is important through better management. By analyzing traffic, urban planning can reduce congestion. Population increase in Samarinda increases traffic and causes congestion. Congestion conditions in Samarinda are getting worse because vehicles continues to increase without road improvements, especially on Jalan Pangeran Antasari. The aim of this research is to evaluate the performance of road sections using the PKJI method, providing a visual of the condition using PTV Vissim software. The survey was carried out for 3 days on Monday 26 February 2024, Friday and Saturday 1-2 March 2024 with a time span of 15 minutes with a duration of 1 hour. Held in the morning at (07:00-08:00 WITA), in the afternoon at (12:00-13:00 WITA), in the evening at (17:00-18:00 WITA). Jalan Pangeran Antasari provides a capacity of 6072 pcu/hour. The highest vehicle volume occurred on Saturday with 2418 pcu/hour, indicating that the road section is in type A with free flow conditions without obstacles, the 10-year forecasting traffic volume is 3579 pcu/hour. Based on the Samarinda City Masterplan, vehicles is estimated to grow 4% in 10 years. If the road capacity in the current year (2024) is still used to serve the vehicles that will pass in the next 10 years then the service level shows type B. Even though the level of service has decreased, the existing infrastructure is still adequate. This reduction is not yet critical so that current road and traffic facilities can still handle so there is no need for additional recommendations.

Abstract

. In the increase in construction projects using lightweight bricks, the amount of waste generated has also increased. To address this issue, this research evaluates the use of lightweight brick waste as a replacement for Mahakam sand in the production of paving blocks according to SNI 03-0691-1996. The experimental method was used with control test objects without lightweight brick waste and test objects with varying amounts of lightweight brick waste. The mixture composition was 1pc:6ps with a water-cement ratio of 0,35, and lightweight brick waste constituting 0%, 25%, 50%, 75%, and 100% of the sand weight. The Paving blocks were made using manual compaction tools. Compressive strength testing was conducted at 3, 7, and 28 days, while absorption testing was done by soaking for 1 day. The results showed that paving blocks with 50% lightweight brick waste had the highest compressive strength at 28 days, reaching 47,81 MPa, classified as class A. The addition of lightweight brick waste also increased the water absorption of the Paving blocks, with the lowest absorption in the 25% mixture at 2,17%, also classified as class A. These findings demonstrate the potential for using lightweight brick waste in the production of environmentally friendly paving blocks.

Abstract

Transportation as an activity of moving something from one place to another. The existence of various community activities causes the emergence of traffic movements. The more activities that take place, the more traffic generated. So that adequate infrastructure is needed to create a smooth movement. As the number of vehicles increases, the strength of the pavement decreases which results in road damage. Pavement in good condition in Samarinda City in 2020 decreased by around 6.3%, while roads in severely damaged conditions increased by almost 100% from 2015. Damage to pavement reduces the capacity of the previously planned roads. This affects the level of service on these roads, so it is necessary to compare the analysis of service levels with and without any damage. The research was conducted by surveying Ir. Sutami road, City of Samarinda with a length of 150 m. Primary data include the number of vehicles, road geometric data and documentation of road damage. The analytical method uses MKJI 1997. The volume of vehicles passing through Ir. Sutami as much as 1228.4 smp/hour on holidays and 3510.35 smp/hour on weekdays which are dominated by motorbikes. Road capacity Ir. Sutami in a condition without any damage, namely 6079.92 smp/hour which produces a V/C ratio of 0.58 with a service level of A, while currently the Ir. Sutami road with some damage such as holes and peeling so that the capacity decreased to 5251.067 smp/hour with a V/C ratio of 0.67.

Abstract

Piles are used as the foundation for a building's construction when the underlying soil beneath the structure lacks sufficient bearing capacity to support the weight of the construction and its load, or when hard soil with enough bearing capacity lies at a significant depth. Retaining walls are a type of civil construction built to withstand the lateral active pressure of soil or water. Therefore, the construction of a retaining wall must be planned and designed to safely counter potential forces that could cause structural failure. The purpose of this writing is to understand the implementation of mini pile foundations and retaining walls concerning the stability control of the retaining wall against sliding, overturning, and soil-bearing capacity. The observational method used involves collecting secondary and primary data. The mini pile foundations are driven to a specified depth, with each pile segment being 4.0 meters long, and this piling activity aligns with the plan. The retaining wall used is a cantilever retaining wall with concrete quality K-300 f’c 25 MPa, where the successive heights, upper width, and bottom width of the retaining wall are 4.5 m, 0.3 m, and 2.7 m, respectively.

Abstract

This study investigated volumetric analysis on asphalt concrete mixtures containing fly ash filler and glass powder waste filler, focusing on the response to local inundation of seawater. This study investigated volumetric analysis on asphalt concrete mixtures containing fly ash filler and glass powder waste filler, focusing on response to local inundation of seawater which includes Stability, Flow, VIM, VMA, and VFB. In the 4-day seawater puddle model cycle, 12 specimens were made: 3 fly ash fillers, 3 glass powder waste fillers, and 3 normal asphalt, tested for 5 hours and 10 hours. This study explores the impact of fillers and inundation cycles on asphalt concrete characteristics. To realize the model of seawater puddles, in cylindrical specimens PVC retaining rings of the same diameter as the specimen (100 mm) are used tightly covered with silicone on the specimen surface. Filler with glass powder has low hygroscopic properties, which can help reduce moisture absorption in asphalt mixture beyond filler with fly ash. This can reduce the risk of changes in mechanical properties due to high water content. This study can provide an analysis of how well the asphalt mixture is able to withstand moisture and the extent to which glass powder filler and fly ash filler affect the absorbency of the mixture.

Abstract

The development of construction encourages increased development so as to create innovations in the development, one of which is used of road pavement materials which were originally dominated by asphalt, has now varied with paving blocks. Using waste as a mixture in making paving blocks is an alternative to creative and innovative products. In this case making paving blocks with brick waste, the waste increases along with the number of lightweight brick enthusiasts. The purpose article is to determine the strength value of paving blocks made from brick waste and tenggarong sand as a mixture of lightweight brick waste. The mixing ratio of cement and sand used was 1:6 with variations in the mixture of lightweight brick waste 0%, 25%, 50%, 75% and 100%. The tests carried out were water absorbtion and compressive strength. Data collection by testing in the laboratory on the materials used are sand tenggarong, cement three wheels and CLC lightweight brick waste. The results show that the most optimal percentage of the use of brick waste is at a percentage of 25% at the age of 28 days has a compressive strength value of 28.85 Mpa thus included in the quality of class B (parking lot). While the other percentages do not match between the compressive strength and the absorbtion value that has been determined. Research on compressive strength and water absorbtion of paving blocks can be the basis for further research such as testing the wear of paving blocks using brick waste as a mixture.
