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.

Abstract

The occurrence of flooding in the Batang Sumani area of ​​Solok Regency is caused by several things, including the low slope of the river, the river cross-section which is not wide enough, the topography of the plains, heavy bends along the river and silting due to sedimentation and the vulnerability to flood hazards which is quite high in the watershed area. The influence of the topography of the plains causes inundation on land managed and used by the community. In accordance with technological developments in digital mapping of the earth's surface, the earth's surface can be presented in the form of a three-dimensional map called a Digital Elevation Model (DEM). This DEM is used as a model, analysis and representation of conditions related to the earth's surface. The use of DEM in the process of analyzing inundation caused by surface runoff will help in identifying the coverage of inundation areas and water catchment areas. By using the Simulate water level rise / flooding analysis from the Global Mapper application it is possible to simulate water level rise / flooding which makes it possible to simulate the coverage or spread of water/flooding by increasing the water level to a certain depth and spatial analysis using the Geographic Information System can see the influence of the inundation area on land use managed by the community around the inundation area. So that the location and coverage of the inundation on land use can be obtained. Most of the inundation areas are in garden areas at 37.56%, rice fields at 23.83%, fields at 24.03% and residential areas at 13.67%. There was a significant increase in the water level rise of 2 meters.

Abstract

Flexible Pavement is one of the road pavement constructions. In order for the flexible pavement to have adequate carrying capacity and durability to carry the load acting on it, the pavement is made in layers. The top layer is called the surface layer and below it is an aggregate foundation layer which is placed on top of the compacted subgrade. The material used as an aggregate foundation layer usually consists of crushed stone. However, seeing the abundance of limestone in Bukit Karang Putih, Indarung is expected not only to be used cement manufacture, but can be used as a substitute for the aggregate foundation layer. This research was conducted on the aggregate foundation layer of class A and the aggregate foundation layer of class B. Variations of mixture with limestone substitution in the aggregate foundation layer of class A and class B aggregate are 0%, 10% and 20%. The tests carried out include abrasion, compaction and CBR. The lowest abrasion test results for grade A aggregate foundation layer is 30.69%, while for grade B aggregate foundation layer is 31.79%. The results of the CBR test for class A aggregate foundation layers obtained the highest value for 10% limestone substitution, which is 75%, as well as for class B aggregate foundation layers, the highest value for 10% limestone substitution was 61%. The results of the CBR test that meet the requirements are found in the class B aggregate foundation layer, which is at least 60%.

Abstract

The Padang-Solok road section is one of the national road sections that frequently experiences accidents every year. The aim of this research is to determine the factors that cause accidents on the Jalan Lubuk Paraku Sitinjau Lauik section based on the accident rate, and find out alternative prevention solutions future traffic accidents. This type of research is descriptive research using the Accident Rate method. The factors reviewed are the total number of accidents that occur and the length of the road section studied. An Accident Rate value > 1.0 will be classified as a Black Spot, while a value < 1.0 will be classified as a Black Site. The results of the accident analysis based on the Accident Rate can be identified in three road sections that show a high accident rate, namely more than 1.0. The highest accident rate was on the Panorama 2 – Padang-Solok City Limits road section at 2.37 accidents/km.year. The most dominant factor causing traffic accidents is the human factor. After an inspection was carried out, the brakes failed due to the large number of descents or steep inclines which made the car brakes not function properly. An alternative solution for preventing accidents is to create a temporary stopping place at the Padang - Solok city limits to cool down the engine and car brakes, repair traffic signs that are not yet permanent and create a special brake rescue lane for broken brakes at Panorama 2 and near the rice fields PU Mes.
