Abstract

The global population growth increased by 0.88% at the end of 2022 compared to the previous year. Jakarta and Singapore, as two densely populated areas in Southeast Asia, need to pay extra attention to the need for infrastructure, including adequate transportation systems. One of the prominent transportation modes in both regions is Mass Rapid Transit (MRT). MRT is an urban rail-based transportation mode aimed at providing regular and sustainable public services. The MRT system excels in capacity, speed, and reliability compared to other transportation modes, as it operates on fully separated tracks. Despite both regions having MRT systems, there are differences in several aspects. This research is conducted using a qualitative method, applying techniques such as the analysis of literature. The differing aspects between the Jakarta MRT and the Singapore MRT are headway (time between trains) and payment methods. The Singapore MRT has a smaller headway compared to the Jakarta MRT. The shorter the time, the better the service. In terms of payment methods, the Singapore MRT predominantly implements a cardless payment system, in contrast to the Jakarta MRT. The Jakarta MRT still offers the purchase of Single Trip Tickets and Multi Trip Tickets.

Abstract

The threat of flood disasters when the rainy season arrives is a big problem currently being faced by the city of Jakarta. The city of Jakarta, which is the nation's capital, has made this city a business center and metropolitan city, so that development of both structures and infrastructure is growing rapidly, as a result of this large amount of development, this will automatically reduce the availability of open land, resulting in less and less rainwater infiltration over time. In addition, rainwater as a source of clean water has been considered wastewater which can cause gloves and must be channeled downstream as quickly as possible so that rainwater is not given the opportunity to seep into the soil through infiltration and percolation processes which are conditions This will have an impact on the availability of water on land becoming less. Based on the problems above, a method is needed to optimize drainage performance in order to overcome flooding and the scarcity of water sources. One of them is using a sustainable drainage concept. This concept aims to reduce inundation due to surface flow and conserve water. The research method used was a survey, data analysis using hydrological and hydraulic analysis. The research case study was carried out at the Central Jakarta State Secretariat housing complex with the results of the analysis of the implementation of 30 infiltration wells with a diameter of 0.8 meters and a well depth of 2.4 meters. From the research results, it was found that one infiltration well can hold 1.2063 m3 of water and the well filling time is 51 seconds. So for 30 wells the reduced rainwater discharge is 36.189 m3 during 51 seconds of rain, while the planned flood discharge during 51 seconds of rain is 38.25 m3 and if the percentage is calculated, the reduced rainwater reaches 94.61%.

Abstract

Abstract Land transportation traffic accidents in Indonesia were affected by the Covid-19 pandemic. During the Covid-19 pandemic, several transportation policies were implemented. An absolute must for implementing transportation safety. During the Covid pandemic in 2019 and 2020, the average number of traffic accidents was 25%, the number of fatalities was 24%, the number of injured victims was 21% and the number of accidents was 25%. In 2021, Indonesian people will begin to face new normal conditions, where all activities run normally in line with the presence of the Covid 19 virus. So that in 2021 and 2022 there will be another increase in the number of traffic accidents, deaths, injuries and accidents. The average figures for 2021 and 2022 for the number of traffic accidents are 26%, the number of fatalities is 26%, the number of injured victims is 23% and the number of accidents is 28%. With the presence of Regulation Number 21 of 2020 concerning PSBB, the number of accidents in Indonesia can be reduced, but the reduction in the accident rate has not occurred significantly. In 2019 the accident rate was 31% and in the year the PSBB policy was implemented the accident rate was 23%, the reduction in the accident rate was only 8%.

Abstract

Self-compacting concrete (SCC) is a type of concrete that has the ability to flow and consolidate itself without the need for vibration. The addictive substance for self-compacting concrete uses chemical plasticizers produced by concrete chemical companies. The nature of the plasticizer material is usually liquid and thick which is used to thin the mixture and increase the workability of the concrete. The research began by creating a mix design including preparation of the need for natural additives. Testing the thinness of the concrete mix can be carried out using a flow test or fresh concrete spread test, where SCC meton meets the criteria if it gets a minimum spread test diameter of 50 cm. Some natural materials that are thick in nature include aloe vera sap, egg white, snail mucus and others. Tests using plasticizer fabricated products from Sika Viscocrete 3000 had the highest Flow values ​​for SCC concrete, followed by Sugar Solution, Allovera, Egg White and Snail Liquid. The results of successive cylindrical concrete compression tests produced average strengths ranging from Sika Viscocrete 23.6 Mpa, Allovera 14.23 Mpa, Snail 13.75 Mpa, Egg White 11.0 Mpa, and Sugar 3.1 Mpa. Fabricated plasticizers have very good results as additional materials for Self Compacting Concrete type concrete, while the natural material that still has potential in terms of flow is sugar solution, while in terms of compressive strength it is allovera.

Abstract

Panti Rahayu “Yakkum” Hospital Purwodadi has provided three parking spaces that are still within the hospital complex. In the parking area, it is currently unknown what the characteristics of parking and how much parking space is needed. This study aims to determine the characteristics of parking, capacity, and the need for existing parking spaces. The research method used is the observation method and literature study. This study was conducted for 3 days, namely Saturday, Sunday, and Monday, starting at 08.00 – 20.00 (12 hours) with a recorded time interval of 15 minutes. The results obtained were 602 vehicles for the highest parking volume for motorcycles and 156 vehicles for cars, the highest parking accumulation for motorcycles was 469 vehicles and 120 vehicles for cars, the parking index for cars was 122.45%, while for motorcycles it was 87.99%, the average duration of parking for motorcycles and passenger cars was 2.5 hours/vehicle and for parking turnover it had the same parking turnover rate between motorcycles and cars, The parking capacity for motorcycles is 1 vehicle, while for cars it is 3 vehicles. The total capacity for motorcycles is 533 SRP, while the capacity for cars is 49 SRP. However, when viewed from the highest incoming vehicle volume, the parking capacity is insufficient to meet the parking needs of patients, visitors and hospital employees. Researchers recommend that Panti Rahayu “Yakkum” Hospital Purwodadi add parking space or build a multi-story building parking lot.

Abstract

This study aims to analyze the results of contour map creation using the closed polygon method through the Surfer 15 program in the area of ​​the Semarang State Polytechnic Directorate Building, which includes the area of ​​the Directorate Building - PKM - SC Building - Cooperation Building. Contour map creation was carried out to determine the topographic conditions and characteristics of the land slope in the area, which affect the planning and development of campus infrastructure. The methods used in this study include collecting coordinate and elevation data in the field, data processing using the closed polygon method to obtain high accuracy in positioning, and land surface modeling with Surfer 15 software. The results of data processing are presented in the form of contour maps and cross-sections and longitudinal sections, which are then analyzed to determine the level of land slope in each measurement segment. From the analysis results, it was found that the topography in the section of the Directorate Building - PKM - SC Building - Cooperation Building showed significant variations in height. Based on the measurement results, the slope of the land in the cross section A–A (Directorate–PKM) is 5.12%, section B–B (Directorate–PKM) is 3.59%, section C–C (Directorate–SC Building) is 7.94%, and the longitudinal section of the Tennis Court–Workshop Building has a slope of 2.44%. These values ​​indicate that the research area has varying elevation differences, with a tendency of gentle to moderate slopes. Overall, the results of this study indicate that the closed polygon method and modeling with Surfer 15 are able to provide an accurate and detailed topographical picture of the land conditions in the Semarang State Polytechnic environment. This land slope information can be used to support spatial planning, drainage, and the development of more efficient and sustainable campus facilities.
