Abstract

A drainage system is a series of activities designed to drain water from an area or area, including surface water and ground water. Drainage systems are also an important part of urban areas. A well-organized urban area must have a drainage system that functions well, so that it does not cause standing water which can disrupt community activities, especially those related to environmental health. On the Pengging-Banyudono road, Ngaru-ngaru Village, Banyudono District, Boyolali Regency, which is a residential area and sales kiosk, there are still several problems with the drainage system which is not functioning properly and must be addressed immediately. If the rainfall is high enough, it will cause water to pool on the body and shoulders of the road, which can cause water channels to become blocked and disrupt residents' activities. So it is necessary to evaluate drainage channels and handle waterlogging on Jalan Pengging-Banyudono, Boyolali Regency. This research aims to determine the existing drainage system and evaluate the capacity of the drainage channel. From monitoring, there is sedimentation, sedimentation and changes in the cross-sectional dimensions of the channel which trigger blockage of water flow. Meanwhile, the analysis results show that the channel capacity is unable to accommodate the existing flood discharge. In the existing channel, the channel discharge (Qs) is 0.0081m3/second, smaller than the 25 year flood discharge (0.2783 m3/second). This means that the existing channel capacity is not able to accommodate flood discharge. The results of calculating the dimensions of the new channel, obtained the most economical channel dimensions with a channel width of 1.2 m and a channel height of 1.2 m.

Abstract

In the current era of globalization, the need for concrete is increasing, triggering challenges to create good quality concrete. High- quality concrete innovation is developed through the improvement of concrete constituent materials and the addition of added materials. In this study, pozzolan material was used, namely silica fume and marble powder as filler. This concrete is Reactive Powder Concrete, where the constituent material of concrete is nanometer in size and removes coarse aggregate. The method used is experimental. The test specimen used is cylindrical concrete measuring 10 cm x 20 cm. This study aims to determine the optimum level of use of silica fume and marble powder with a variation in 0% levels; 5%; 10%; 15%; 20%; 25%; 30%; 35%; 40%; 45%; and 50%. The results of the study showed the optimum content of silica fume 15% of the total cementitious, and the optimum content of marble powder 30% of the total fine aggregate which obtained compressive strength of 12.74 MPa and 12.10 MPa at the age of 7 days. Then 16 pieces of RPC concrete were made with a test life of 7, 14, 21, and 28 days. Test specimens are given two treatment methods, namely steam curing and immersion. Of the two treatments applied, steam curing produces high initial compressive strength, with a maximum compressive strength of 66.24 MPa at 7 days old. While immersion treatment can produce high final compressive strength in RPC concrete which produces the highest compressive strength of 103.82 MPa at 28 days old.

Abstract

The Jlantah Dam is located in Jatiyoso District, Karanganyar Regency, Central Java. This dam construction has a total storage capacity of 10.97 million cubic meters, with a height of 70 meters from the riverbed, a length of 404 meters, a width of 12 meters, and a crest elevation of +690 meters. The purpose of this study is to examine the slope stability before reinforcing with retaining walls, the slope stability after reinforcement, and the sliding stability, overturning stability, and bearing capacity of the retaining walls. According to SNI 8640:2017, geotechnical design requirements define the slope safety factor. If the safety factor (SF) is more than 1.5, the slope is considered safe, whereas if the safety factor (SF) is less than 1.5, the slope is considered unsafe. The results of the slope stability analysis using PLAXIS 2D V20 software without retaining wall reinforcement show an SF = 1.253. The slope with reinforcement achieved an SF = 1.640. Using Geo5 2020 software with the Bishop method, the SF is 1.70, and with the Fellenius method, the SF is 3.36. For the retaining wall stability using the manual method, the sliding stability SF = 3.90, the overturning stability FS = 7.05, and the bearing capacity of the retaining wall FS = 12.25. Meanwhile, using Geo5 software, the sliding stability FS = 2.51, the overturning stability FS = 1.81, and the bearing capacity of the retaining wall FS = 3.36.

Abstract

National road projects usually use flexible pavement types because they can adapt to diverse soil conditions and are comfortable to use. In the construction project for JLS Lot 1A Brumbun – P. Sine, there is soft soil condition at STA 4+050 with low CBR value, while at STA 5+315, the CBR is high due to excavation of soft rock. However, throughout the planned road, only one thickness design of the pavement is used. The location also has subsoil that often experiences water seepage, causing saturation and potentially leading to consolidation and ground settlement. Therefore, a study was designed to analyze the effect of variations in CBR values on pavement thickness and provide recommendations for pavement thickness that can prevent ground settlement due to saturated soil, considering the thickness of the layers based on field CBR values using MDPJ 2017, Pt T-01-2002-B, and MDPJ 2024. The data collection method used secondary data from the project and conducted a literature study, resulting in the finding that the CBR of the subgrade can affect the thickness of the pavement in terms of the foundation layer thickness. Recommendations for the thickness of the flexible pavement layers using the MDPJ 2024 method are 4 cm for AC-WC, 14.5 cm for AC-BC, 20 cm for Class A LPA, 15 cm for Class B LPA, and a cement stabilization thickness of 20 cm for CBR <10% and a stabilization thickness of 15 cm for CBR >10%

Abstract

One type of mortar used in the process of making walls and plastering is lime mortar. In this study, marble waste will be utilized to increase quality. The use of waste marble as a substitute for a portion of the weight of cement can produce a plastic mortar, making it easy to work with and the mortar is more watertight. Because marble waste has a fairly high calcium content, it is hoped that it will be able to become a binder and can reduce cement during the mortar making process. This study discusses the effect of mortar with marble waste substitution of 0%, 20%, 25% and 30% by weight of cement. Compressive strength testing was carried out at the age of 3, 7, 14, 21 and 28 days. From the test results it can be seen that for all variations of mortar there has been an increase in both the bulk density of the mortar and the compressive strength of the mortar at each age, but has no effect on the addition of the value of the unit weight or compressive strength on the normal mortar, with the optimum value found in the addition of marble waste powder of 25% results in a compressive strength of 15.33 MPa with a bulk density of 2.04 gram/cm3. Judging from the compressive strength obtained based on SNI 03-6882-2002 concerning mortar specifications, for all variations of mortar including type S lime mortar.
