Abstract

The behavior of river flow patterns on the condition of the pillar dimensions can affect the geomorphology conditions of the river, namely the unbalanced local scouring between sediment transport and sediment supply so that it will affect the strength of the pillar. This study aims to study the effect of pillar dimensions on scour depth and channel base changes in the pillar area. The method of observation was carried out by simulations using Nays2DH with the same parameters for each test of each dimension with discharge (Q) = 0.5 m3/s, sediment diameter (D50) = 0.35 mm, channel width (B) = 5 m, channel length (L) = 25 m, slope (i) = 0.005 and drainage time (t) = 7200 s. The simulation results show the basic scour pattern of the channel which has the smallest value, the diamond type pillar. Degradation - Basic channel agitation on diamond type pillars, showing a pattern that tends to be evenly distributed compared to semi rounded, rectangle, or octagonal types. Period (t) 7200 s downstream of the pillar, semi rounded type scours change <0.3 m, rectangle type scours changes <0.4 m, octagonal type scours changes <0.4 m, and diamond type scours changes <0.2 m. So the dimensions of the diamond type are more effective in reducing the depth of scour.

Abstract

City parks are again crowded with people after COVID-19 to play, exercise and recreation, and Adipura Muara Enim Park is no exception. The Covid-19 pandemic is not certain to end. For this reason, the facilities available in city parks in the new normal era need to be conditioned so that they can provide optimal services and can support the government's efforts in handling COVID-19. The aim of the research is to analyze the need for infrastructure facilities and get the "level of service" (LOS). The research used a descriptive survey data collection method in the form of observing physical settings, functional aspects and similar research theories and then distributing questionnaires with several variables, namely the level of service facilities, level of activity level, significance and level of ease of achievement. Attitudes were assessed using a Likert scale and the "level of service" (LOS) analysis method. The results showed that the level of service at Adipura Muara Enim Park was F (< 5), that is, there was an accumulation of user activity due to the uneven distribution of facilities. It is necessary to add and adjust the facility design to meet the new normal criteria, including: the addition of an outdoor gym, guard post, information media boards, hand washing facilities, body temperature measuring device, pavement material pattern as a spacer, single seats, vegetation as a barrier between facility.

Abstract

Cement, as a concrete-forming material, is a contributor to CO2 emissions in the world. Reducing cement and substituting fly ash and silica fume as concrete substitution materials in the manufacture of concrete makes green concrete without lowering the quality of the concrete. Concrete in the marine environment is frequently destroyed by severe environmental elements, such as seawater penetration; hence, high-performance concrete materials are required. This research aims to analyze the effect of adding fly ash and silica fume on concrete compressive strength and permeability. The specimens made were then immersed in freshwater and seawater. Analysis of the compressive strength test result shows that the compressive strength values ​​for the samples treated with freshwater or seawater have exceeded the expected compressive strength of 30 MPa. The permeability test on the test object resulted in the supplementary fly ash to the concrete immersed in freshwater having a good value, i.e., the water penetration was below that required by DIN-1045, namely 5 cm. The penetration of concrete with fly ash impressed in seawater is good only in concrete with a 10% fly ash variation. The water penetration value still meets the requirements in concrete with silica fume for all variations with freshwater and seawater treatment.

Abstract

Pemerintah Indonesia telah berupaya untuk mengurangi kemacetan lalu lintas di jalan tol dengan menerapkan sistem transaksi tol non tunai yang berlaku di seluruh jalan tol Indonesia sejak tahun 2017. Namun kepadatan lalu lintas menyebabkan kemacetan lalu lintas di jalan tol di perkotaan sering terjadi. Penelitian ini bertujuan untuk mengetahui faktor-faktor yang mempengaruhi perkembangan sistem transaksi tol dan sejauh mana distribusi kendaraan melalui preferensi pengguna jalan dalam memilih masuk jalan tol atau tidak. Metode penelitian ini menggunakan pendekatan deskriptif kuantitatif. Respondennya adalah pengguna kendaraan golongan I – V yang melintasi Prof.Dr.Ir. Tol Soedijatmo dengan arah perjalanan dari Tol Intra Urban Jakarta. Hasil penelitian menunjukkan penerapan ETC tol contactless cashless dapat menurunkan minat pengguna jalan untuk memasuki jalan tol jika dikenakan denda, namun di sisi lain pengguna jalan masih sangat berminat untuk memasuki jalan tol. Terjadi peningkatan sebaran volume lalu lintas karena jumlah kendaraan menurun seiring dengan berkurangnya minat pengguna jalan untuk memasuki jalan tol akibat kenaikan tarif tol yang semakin tinggi.

Abstract

High domestic consumption of coal, especially in energy sector, has raised concerns on several environmental issues in Indonesia. Large amount of coal combustion product in the form of solid waste, such as fly ash resulting from coal power plant production causes problems in its disposal since its necessity of land occupancy. Over the last decade, many researchers have put effort to solve this disposal concerns by utilizing these materials for various purposes, such as construction materials as part of circular economy. This paper presents the utilization of fly ash for soil stabilization in Surabaya. Firstly, the index properties of soil samples were determined through a series of laboratory soil test including specific gravity, unit weight, moisture content, sieve analysis and Atterberg’s limit tests. Subsequently, standard proctor test was conducted to obtain the maximum dry density and optimum moisture content of the soil samples. Using those parameters, four types of soil stabilized with fly ash samples were prepared with fly ash content based on weight of soil as follows: 0%, 5%, 10%, and 15%. Finally, unconfined compression tests were performed with cylindrical soil samples to assess the unconfined compressive strength of those samples. The results indicate that soil with fly ash content of 10% showing the highest unconfined compressive strength compared to the other variations of 0.90 kg/cm2.

Abstract

Indonesia is geographically located in the Pacific Ring of Fire, Especially on Java Island, which has the densest infrastructure and population and is located between the Indo-Australian plate and the Eurasian plate, causing this area to have many active volcanoes and has a high potential for earthquakes. Therefore, it is necessary to pay the planned earthquake load in planning the building structure design to minimize losses due to the earthquake. This study aims to determine the structure's performance against safeguards, deviations between levels, and structural stability limits against earthquake loads and to review horizontal structural irregularities based on SNI 1726: 2019 regulations in existing buildings at the Simpang Temu MRT Dukuh Atas Jakarta Building. The analysis process was carried out by 3D building modeling using the ETABS software program, analysis based on time history and spectrum response. Time History analysis uses recorded earthquakes of Kobe Japan, ChiChi Taiwan, and El Centro which match the earthquake response spectrum, the results of the analysis based on the program were carried out to compare the two methods used. Based on the results of the analysis, the building is classified into horizontal irregularities with excessive torque ratio > 1.4, average displacement value from the 2nd to 12th floor in the horizontal direction X exceeds the drift value limit. The results of the instability limit for structural stability against displacement based on the P-Delta effect still meet the structural stability limits so it can be stated that the structure is stable and safe.
