Abstract

Geopolymer concrete is a type of concrete that utilizes waste materials as a substitute for Portland cement. One of the most commonly used waste materials in geopolymer concrete is class F fly ash. Based on experimental research, class F fly ash has the potential to act as a binding material in geopolymer concrete mixtures. Several studies have indicated a significant relationship between class F fly ash and the strength and durability of geopolymer concrete. However, other studies have not supported this statement. To address this issue, a literature review was conducted to examine the performance of fly ash-based geopolymer concrete in terms of strength and durability. The data used in this study were derived from 25 research journals, comprising a total of 126 specimens. These specimens were categorized based on the results of strength and durability tests. Strength was evaluated using compressive strength tests, while durability was assessed through water absorption, exposure to elevated temperatures, and exposure to chemical substances. The study focused on analyzing the effect of fly ash percentages on the strength and durability of geopolymer concrete. The analysis methods applied in this study included visual graphics and regression statistics. Based on the findings of the collected data, it was concluded that fly ash, as a precursor, does not have a significant effect on either the strength or durability of geopolymer concrete.

Abstract

With the provision of feeder mode (Feeder) train, which consists of Feeder Train and Commuter Line Bandung Raya, it will provide several alternatives for passengers who will continue their trip to the center of Bandung City. Under existing conditions, the Feeder Train experienced a significant increase in interest compared to the Commuter Line Bandung so that there is a gap in the probability of Feeder Train passengers with Commuter Line Bandung Raya. This is what makes researchers feel the need to analyze passengers' preferences in choosing the next mode of transportation and get an understanding of what factors influence the choice of transportation and sensitivity to the model. The number of samples from this study amounted to 96 respondents with data analysis methods using logistic regression analysis and binary logit difference analysis. Based on the results of logistic regression analysis, the following difference utility function model is obtained: PFeeder = 1/(1+ e^(-(0.442 + (X1) + 0.122 (X2) + 0.023 (X3) + 0.020 (X4) + (X5))) with PFeeder = Probability of Feeder Train, PCL = Probability of Comline Baraya, X1 = cost, X2 = frequency, X3 = travel time, X4 = headway, X5 = capacity. From the model, a higher probability of choosing Feeder Train is obtained with a probability value of 61% and the probability value of Commuter Line Bandung Raya is 39%. In other words, respondents still tend to choose Feeder Train to be used as a further mode of transportation, with influencing factors based on test results with high significance, namely cost, time and headway. From the results of the sensitivity analysis of the cost, travel time and headway variables, the cost variable is the most sensitive variable if there is a change in value on the attribute compared to the travel time and headway variables.

Abstract

Dewatering is required to control the flow of groundwater and to lower the position of the groundwater table during excavation. In planning the dewatering system, parameters related to the flow of water in the soil are required. One of these is the conductivity value, which can be obtained from pumping tests. The sand layer found on the ground surface, which is saturated of water, is referred to as an unconfined aquifer. In this study, conductivity analysis of unconfined aquifer was conducted in PIK2 area using 3 conventional methods which are, Thiem (1906) method and curve matching method of Boulton (1963) and Neuman (1972). Conductivity values obtained from conventional calculations are then analyzed using the help of a program based on the 3D finite difference method Modflow to obtain a pattern of groundwater level decline or can also be called a depression cone. In sandy soil in the PIK2 reclamation area, conductivity values of 5.90×10-5 m/s to 8.08×10-5 m/s were obtained Neuman's method can produce better conductivity values in unconfined aquifers, as shown by the results of the water table profile from the 3D Modflow analysis.

Abstract

Sarang Tawon water purifier uses filtration principle which is done repeatedly through certain filter media that are arranged in layers. The water quality as the filtration result is influenced by the filtration system and the type of filter media used and the duration of purifying process. The factor of thickness and filter media density were neglected until causing problem in the duration of water purifying process. This research aimed to find out the influence of thickness difference and filter media density of Sarang Tawon water purifier towards the parameter of Total Dissolved Solids (TDS) and pH. The experimental method was applied by testing the thickness of zeolite stone filter media combination, ginger coral, and coconut fiber from the Sarang Tawon water purifier with radius 4R/3, R, and 2R/3 where R=3 inches. The density variations of coconut fiber filter media were 20%, 40%, 60%, 80% and 100%. The research results showed that the thickness of filter media in Sarang Tawon water purifier tool with radius 4R/3 with coconut fiber filter media density was 80% owning the ability to increase the highest pH value. There was increase of TDS parameter in each trial caused by the dissolved of ginger coral filter media, but it did not show significant number. TDS parameter resulted by the tool with radius 2R/3 with density variation of coconut fiber filter media amounted 80% showed a relatively stable value.

Abstract

Infrastructure development leads to the cutting of slope dan additional construction loads on crest. Although the impact of slope cutting and additional construction loads on slope stability has been taken into account, several processes that follow, such as increased pore water pressure caused by rainwater seepage and the occurrence of cracks on the ground surface, can trigger slope failure. This article presents a stability analysis of a natural slope that has been cut to make room for the construction of a new road below the existing road. The stability analysis shows that the slope is in a stable condition before (FoS = 1.694) and after the construction (FoS = 1.423). However, the slope collapsed after heavy rain for 3 days on July 20th – 22nd, 2022. The failure plane starts at the crest of the slope, which is in the middle of the existing road, and ends at the toe. Seepage analysis carried out due to rain infiltration by considering the position of the crack as the starting point of the landslide plane, shows that there is an increase in pore water pressure in the slope, and the FoS decreases to 0.973. Remedial work carried out after a failure includes realigning the existing road, strengthening the toe of the slope with a retaining structure, covering the slope surface with vegetation, and arranging surface drainage.

Abstract

Bundaran HI bus stop is one of the public transportation system infrastructures where this bus stop is one of the busiest due to the change in transportation modes. Currently, the bus stop looks more modern, narrow, crowded, and uncomfortable for service users. This is used for commercial purposes as a place for taking pictures and tourism. The research objective is to analyze the influence of facilities and service quality on BRT passenger loyalty, to determine the level of customer satisfaction that influences BRT services and to determine the perception of BRT users towards the revitalization of the bus stop. The method chosen is quantitative with data collected through a questionnaire survey of 442 respondents. The analysis method uses descriptive statistics and inferential statistics. Non-parametric statistical tests with Mann Whitney. While the customer satisfaction test uses a Likert scale. The results of the Mann Whitney test study where the Asymp.Sig. (2 tailed) value of 0.032 is smaller than the probability of 0.05, meaning that there is an influence of facilities and service quality on service user loyalty. A satisfaction level of 25% means dissatisfied/less good. Public perception of the revitalization of the Bundaran HI bus stop is negative. The recommendations for the government do not need to be built excessively and luxuriously, so that it does not become an example for other big cities. There is need to be a typical bus stop whose functions and benefits can be imitated, such as getting used to reading literature while waiting for the bus to arrive.

Abstract

Assessment of Beach Damage in Teluk Ambon Sub-district and Prioritisation of Handling. In the management of coastal areas, the assessment of the level of damage to coastal protective buildings is an initial planning step in controlling, preventing, protecting and restoring damage to land, infrastructure and public infrastructure in coastal areas. Assessment or evaluation of the level of coastal damage is needed to find locations of coastal damage that require immediate action. This research was conducted to assess the level of coastal damage and prioritize the handling of coastal protection buildings along the Teluk Ambon sub-district which consists of 8 districts / villages which are then divided into several segments. Each segment was separated by the estuary or edge of the coastal protection structures under review. This study starts by collecting data on damage to coastal structures, analyzing it, then weighing the level of damage and determining the priority of handling. The assessment was conducted in reference to the Circular Letter of the Minister of Public Works No. 08/SE/M/2010 on Guidelines for Beach Damage Assessment and Prioritization of Handling. The coastal damage parameters analyzed include damage/failure of coastal buildings with EA-2 code. The results showed that there were no beach buildings that suffered very heavy (ASB), very heavy (AB) and heavy (B) damage. Coastal buildings that experienced moderate damage (S) with less priority (D) were located in segment 4b of Laha Village. Coastal structures that suffered minor damage with no priority are in segments 1 to 4 of Hunuth Village, segments 1 to 5 of Poka Village, segments 1 to 3 of Rumah Tiga Village, Segments 1 and 2 of Wayame Village, segments 1 to 8 of Hative Besar Village, segments 1 to 4 of Tawiri Village, and segments 1 to 4a of Laha Village.
