Abstract

Batam City is one of the cities in the Riau Archipelago Province with the largest population growth. Along with the development of the city and the increase in population, the need for public facilities and infrastructures also need to be developed, such as on Jalan Siliwangi. Jalan Siliwangi is one of the roads in the Batu Besar area, Nongsa sub-district in Batam city which is experiencing problems with the drainage system. Drainage is a technical measure to prevent excess water due to high rainfall intensity and drain it to a collection point. Rainfall intensity is a condition where rain is highly concentrated and occurs at a certain time. This research was conducted to know whether the Siliwangi Road drainage channel is working optimally so that it can accommodate water during high rainfall. This analysis uses the Gumbel method using extreme values. The extreme values of rain intensity that will be taken into account are several return periods, namely 2, 5, 10, 25, 50, and 100 years. The calculated channel discharge using location data is Q = 0.5637 m3/second, while the planned discharge calculated using rainfall data is Q = 2.064 m3/second. From the results of the analysis of the dimensions of the planned canal found in the field, it does not meet the design capacity so waterlogging occurs, where the height and width of the planning canal are larger. By using the frequency distribution formula of the Gumbel and Log Person Type III methods for the calculation and application of parameters related to the analysis of average data, standard deviation, and determining the frequency of rainfall for the T-year return period in the discussion above, it can be concluded that the drainage channel on Jalan Siliwangi Batam unable to prevent inundation or flooding during high rainfall.

Abstract

Batam City is a city with high attractiveness for tourists, both local and foreign tourists. In an effort to support and accommodate tourists visiting the city of Batam, the construction of hotels and apartments has been intensively carried out. Due to limited land, the high rise building model is one of the most effective building models to build. To guarantee high rise building performance, it is necessary to plan well in design from a structural point of view. In this case foundation as one of the elements of the structure is also an important part, so it needs to be planned well too. The bearingXcapacity of theXfoundation and the settlement in the foundation areXtwo important things that need to beXconsidered in foundation planning. In this study, an analysis of the bearing capacity of the foundation using the Meyerhof method and the finite elementXmethod (Plaxis 2D) and foundation settlement analysis using the elastic reduction method and the finite elementXmethod (Plaxis 2D) was carried out on the Mega Techno City Apartment construction project in Batam. The results of this analysis are in the form of bearing capacity based on the Meyerhof method is 3.330,8 kN and 3.351,6 kN based on the finite element method, as for the settlement, 53,1 mm is obtained for the elastic settlement method and 9,64 mm for the finite element method, the settlement still meets the SNI 8640 – 2017 standard. Based on these external differences, it can be used as a reference in conservative design.

Abstract

Design discharge is discharge with a certain return period which is used as a reference or parameter in a water building construction planning. Calculation of the design discharge can be done by using the synthetic unit hydrograph method. The calculation of the planned discharge using the Nakayasu and SCS-CN synthetic unit hydrographs aims to compare the calculation of the maximum discharge in the Pesung Watershed, Batam. The design discharge analysis was carried out without calibrating with AWLR data (observed flow) due to the unavailability of AWLR data at the study site. Thus, in this study using HDRO (high direct runoff) as a comparison. The purpose of this study is to estimate the magnitude of the design flood discharge in the Pesung Watershed, Batam City. The methods used in this calculation of the flood hydrograph is using an empirical formula, namely SCS Synthetic Unit Hydrograph and Nakayasu. The results of the HDRO calculation analysis show that the largest flood discharge occurs in the Nakayasu synthetic unit hydrograph method with details of the SCS synthetic unit hydrograph method, the peak time (Tp) is obtained at 4.46 hours, with a return period flood discharge of 5 – 50 reaching 215,488 – 584,308 m3/ s. Whereas in the Nakayasu synthetic unit hydrograph method, the peak time (Tp) is obtained at 1.47 hours, with a return period flood discharge of 5 – 50 years reaching 360.526 – 986.535 m³/s.

Abstract

Liang Village Beach is an area located in the north of Ambon Island, with great marine tourism potential. However, the coastal part of this village experienced erosion marked by the resignation of the coastline and the erosion of agricultural land. This study aims to find out, analyze erosion and coastline changes using the CERC method. The variables observed are the distribution of sediment particles and the pattern of coastline changes, so that it can be estimated the area affected by sedimentation and erosion in the range of 1, 5, and 10 years in the future. The data used are data on the initial coastline, coastal slope, specific gravity of seawater (1.025 tons/m3.) and gravity of the earth (g) (9.81 m/s2). The wave data required in numerical calculations consist of the height of the rupture wave (Hb), the depth of the ruptured wave (db), the rapid propagation of the ruptured wave (Cb), and the angle of incidence of the ruptured wave ( ). Based on numerical calculations, the change in the coastline of 1 year, 5 years and 10 years is the retreat of the coastline (erosion) that occurred on the coast of Liang Village. The changes that occur are caused by waves that are more dominant for the northwest and north, causing erosion along the coast, therefore there is a need for alternative countermeasures such as Revetment to prevent further erosion and accretion on the coast of Liang Village.

Abstract

Indonesia has the many area of the lime production including in the West Sumatra Province. The use of lime as a filler in asphalt mixtures is expected to improve the performance of asphalt mixtures. There are two types of lime used, namely Palupuh and Rao-Rao limestone. This study aims to see the effect of using these 2 types of lime as a filler on Asphalt Concrete-Wearing Course (AC-WC) pavements mixture. The bitumen used is Pen 60/70. Marshall testing was carried out to see the characteristics of the pavement mixture. From Marshall's testing on a pavement without lime, has an optimum asphalt content of 6.015%. Furthermore, with a variation of lime 0%, 25%, 50%, 75%, 100% by weight of filler for both types of lime gave an optimum lime content yield of 50% with an increase in stability of 12.024% and flow of 19.375% for Palupuh lime. Meanwhile, the use of Rao-Rao lime cannot improve the Marshall stability of the AC-WC pavement mixture

Abstract

The increase in world oil prices has led to changes in the price of fuel oil (BBM) in Indonesia. The fuel price change policy impacts various sectors, including the transportation sector. Transportation is one of the basic human needs for moving from one place to another. Various factors are taken into consideration by the community in choosing the mode of transportation to be used. This study aims to analyze the impact of changes in fuel prices on preferences for transportation modes in urban Yogyakarta and to see how people's behaviour changes in mobility. The analytical method used in this research is descriptive and crosstab analysis. Descriptive analysis was used to identify the respondents' characteristics, the journey's characteristics, and the effect of rising fuel prices. Crosstab analysis is used to see the relationship between the characteristics of respondents and the choice of transportation mode before and after the fuel price increase. The data collection method was carried out by distributing questionnaires to the people of Yogyakarta. The choice of transportation mode when fuel oil increases does not change much, whereas in the scenario of changing fuel prices, there is a significant increase. This can be seen from the decrease in car users when there is an increase in the price of fuel oil, while the probability of motorcycle users when the fuel price rises until the fuel price is Rp 12,000 continues to increase, while when the fuel price is Rp 14,000 switch to using public transportation modes, namely the Trans Jogja bus. When the price of fuel oil increases, the frequency of primary trips does not change, while the frequency of secondary trips changes. Transportation costs incurred have increased, and the fuel used has changed; from the first, Pertamax switched to pertalite

Abstract

This study analyzes the road conditions in Sumbawa Regency and plans pavement solutions to address road damage. The data shows that there was no significant improvement in road conditions in 2020 compared to previous years. Good and fair road conditions only accounted for 69.29% of the total road length, while damaged and heavily damaged roads accounted for 6.57% and 24.14% respectively. Jalan Osapsio is one of the roads that has been damaged due to poorly maintained drainage. This research utilizes the Pavement Condition Index (PCI) method to assess the level of road damage and the Component Analysis method to design the pavement thickness. Based on the findings, several road segments exhibit different conditions. There are 13 segments with a Good rating and PCI values of 100 and 98, 1 segment with a Serious rating and a PCI value of 16, and 6 segments with a Failed rating and PCI values of 0. The segments with a Failed rating require urgent pavement reconstruction. Considering the PCI values, it is recommended to construct new pavement with appropriate thickness for the priority segments, namely a 6 cm thick Laston Surface Layer, a 20 cm thick Broken Stone Upper Base Layer, and a 15 cm thick Sirtu/Pitrum Lower Base Layer.This study provides an important contribution in understanding the road conditions in Sumbawa Regency and offers concrete solutions to address the road damage on Jalan Osapsio. The findings and research methodology are expected to serve as a reference for immediate improvements on Jalan Osapsio and provide insights for future research in Sumbawa Regency.

Abstract

In 2021, the population of motorized vehicles in DIY reached 3 million units of which 85% were motorcycles. The growth in the number of motorized vehicles results in increased congestion, pollution, and traffic accidents. To overcome transportation problems in Yogyakarta, in 2008 the government operated BRT (Bus Rapid Transit) based public transportation, Trans Jogja. However, various studies have shown that the load factor of Trans Jogja is very low. This study was conducted to see the characteristics of motorcyclist and latent factors of public transportation services that are prioritized by motorcycle users to switch modes to Trans Jogja. Primary data was obtained online and offline from 455 motorcycle users by answering a research questionnaire consisting of four sections, namely sociodemographic characteristics, travel characteristics and service factors that are prioritized to switch to Trans Jogja. Data analysis was conducted using descriptive methods, crosstab and factor analysis with SPSS. The results of the crosstab analysis show that the sociodemographic characteristics of respondents that correlate with the number of motorcycle ownership are age, income, pocket money, number of family members.Based on the factor analysis of public transport services prioritized by motorcycle users to switch to Trans Jogja, 4 latent factors were obtained, namely Trans Jogja service performance, transit experience, bus facilities and fees and parking.

Abstract

Soft clay has a low bearing capacity, high compressibility and low permeability. This condition causes soft clay soil to have a long settlement time. To overcome this soft soil condition, soil improvement methods are needed. One of the efforts is to use a combination of soil preloading methods, Prefabricated Vertical Drain (PVD), and Prefabricated Horizontal Drain (PHD) methods. Calculating soil settlement with soil improvement is carried out using the Asaoka method, which is a field observation method, and the theoretical method using the Terzaghi method. Based on the calculation results of field observations using the Asaoka method, the average degree of soil settlement is 93.5%. The calculation results of the Asaoka method are recalculated using a back calculation to produce a new parameter value, namely the horizontal consolidation (Ch) value, which is then compared with the Ch value in the previous plan. In the Terzaghi method, the average soil settlement value is 1.205 meters. The results of soil settlement value are used to analyze the height of the embankment based on the load ratio requirement in SNI 8460: 2017, where the load ratio on the ground is ≥ 1.3 times the planned load under service conditions. Based on the monitoring results, a load ratio value of 0.875 was obtained so that the SNI requirements carried out a re-planning of the landfill. Then, proceed with the design of PVD and PHD. The results obtained in planning use triangular PVD patterns with a distance between PVDs of 1 meter.
