Abstract

Pallangga District is the district with the second largest population in Gowa Regency, with a population of 133,027 people or 16.84 percent of the total population in Gowa Regency (Gowa Regency Central Statistics Agency, 2023). The rapid development of housing and commerce has made Pallangga District the most populous area apart from the district capital, namely Sungguminasa. This has also led to changes in land use and an increase in traffic volume, causing congestion. The development of housing and commerce has generated travel generation and attraction around the Sungguminasa City Border Road - Takalar Regency Border Road, but this has not been followed by an increase in transportation facilities and infrastructure, especially road capacity. This shows that land use planning and transportation planning have a relationship that mutually influences each other. This research aims to determine the traffic volume on Jalan Batas Kota Sungguminasa-Batas Kota Takalar Km 0-3.41. The research method used is quantitative analysis by conducting traffic volume surveys and using the 2023 Indonesian Road Capacity Guidelines (PKJI, 2023) as a reference. The results of the research show that road capacity and traffic volume influence the occurrence of traffic jams on the Sungguminasa City-Batas City Border Road, Takalar Regency.

Abstract

Flexible pavement is very weak against waterlogging because water can loosen the bond between aggregate and asphalt. Porous Asphalt has lower durability because it has high pores so that it can be passed by water. Poor bonding of asphalt and aggregate will cause stripping. This peeling can cause water absorption which will eventually accelerate road damage. Derbo 401 anti-peeling material is one of the new breakthroughs, in the form of additives that can change the properties of aggregates and asphalt, increase adhesion and bonding, and reduce the negative effects caused by water so as to produce a mixture of asphalt with high adhesion. The purpose of this study was to determine the effect of adding anti-stripping agent type Derbo-401 to the permeability value and to determine the resistance of the porous asphalt mixture with the addition of anti-striping agent type Derbo-401 in the Cantabro test and to determine the microstructure of the porous asphalt mixture. Using the REAM-2008 Specification. Based on the results of the study, the Permeability Coefficient Value of the porous asphalt mixture was 0.254 cm3/sec. the lowest percentage Derbo 0.4%, the lowest Cantabro Loss value at 0.3% addition percentage gets an average value of 6.13%, Has met the required specifications max 15%. The elements that make up the porous asphalt mixture with the addition of Derbo percentage are more in the elements Si (silicon) 19.93%, Ca (calcium) 21.12%, S (sulfur) 8.45%, Fe (ferrum) 8.80%, K (potassium) 2.42% and the other elements are less.

Abstract

The location of this research was carried out in the mining concession area of PT. Vale site Bahudopi at 22 observation points. This research aims to analyze the characteristics of the soil and rock layers of the research area based on the Cone Penetration Test (CPT). The location of this research was carried out in the mining concession area of PT. Vale site Bahudopi at 22 observation points (Figure 1). The method used in this research is descriptive quantitative, namely, research that describes the conditions of a particular project with existing data, where the results obtained are data in the form of numbers. Meanwhile, data analysis uses quantitative descriptive analysis methods. The characteristics of the soil and rock layers of the research area based on the Cone Penetration Test (CPT) are: In the CPT data group in the northern part, it can be seen that the majority of rocks up to a depth of 4 meters have quite low friction sleeve and cone resistance values, namely below 20 kg/cm2. which indicates that the soil thickness is quite high in most parts of the area. In the CPT data group in the Southern part, it can be seen that the majority of rocks can be seen to have experienced several changes in hardness or pressure values, which can be seen from changes in qc and fs/FR values. From this, it can be concluded that the soil around the CPT data collection area is not homogeneous but still shows a tendency to be composed of the same type of rock but differs in friction sleeve and cone resistance values which could be caused by a high level of weathering so that the composition of the soil layers /soil is quite thick.

Abstract

Mamuju Regency, located in West Sulawesi, is a region highly vulnerable to various types of natural disasters, including earthquakes, floods, and landslides. However, following the earthquakes in January and June 2021, the use of Manakarra Stadium as a gathering point for evacuees revealed significant social issues due to the poorly organized placement of facilities. In this context, Manakarra Stadium is being proposed as an integrated disaster evacuation facility, serving not only as a sports venue but also as a center for protection and recovery for the community. This study aims to design Manakarra Stadium as an effective and efficient evacuation facility in the context of disaster risk reduction. Utilizing a data-driven approach and community needs analysis, the proposed design is expected to make a significant contribution to enhancing disaster resilience in the region. The design of this evacuation facility at Manakarra Stadium could serve as a model for both government and community disaster responses in the aftermath of future events.

Abstract

Ciliwung River is one of the 13 major rivers in Jakarta that causes flooding, especially in the East Jakarta area. In an effort to reduce flooding along the Ciliwung River in the DKI Jakarta area, efforts were made to divert part of the Ciliwung River flow during floods to the East Flood Canal channel through the construction of a double pipe tunnel commonly called a sudetan in the Bidara Cina Village area, where the tunnel also passes through the Cipinang River as a diversion of discharge from the Cilwung River. The purpose of this study is to determine the effect of the sudetan pipe tunnel on the water level of Ciliwung River and Cipinang River. In this study, we will model the water level of Ciliwung River and Cipinang River to see the diversion of discharge into the sudetan pipe tunnel to reduce the overflow of water around Ciliwung River and Cipinang River. The method of this research is done by quantitative descriptive method to the value of water level in Ciliwung River and Cipinang River before the sudetan tunnel and after the sudetan tunnel and looking for comparison by using rating curve. The results of this study are based on the modeling analysis of the maximum flood discharge that can be accommodated by the ciliwung river before the existence of the sewer pipe tunnel in Q1 of 323 m3 / s there is an increase after the sewer pipe tunnel which is 539 m3 / s. It can be seen that the use of a sewer pipe tunnel can reduce the flood water level by 4 meters. It can be seen that the use of tunnel pipes can reduce the elevation of flood water up to 4 meters. Obtained for the ciliwung discharge of the return period Q1=323 m3/det Q2=377.66 m3/det Q5=433 m3/det Q10=462.45 Q25=493.52 m3/det Q50=518.83 m3/det Q100=539.62 m3/det.

Abstract

One of the uses of Buton Asphalt is LASBUTAG which is a road surface with a mixture of Asbuton, modifier and aggregate. Currently, heavy oil as a modifier is scarce in the market, so it is necessary to consider other alternatives as a modifier, one of which can be used, namely waste oil motor vehicle or other machinery. The aim of this study is to analyze the ideal modifier variation in Lasbutag blends using Lombah oil and diesel fuel as modifiers. This research is a quantitative research using experimental methods conducted in the laboratory. The use of the modifier with waste oil and diesel fuel for Lasbutag cold mix pavements can meet the Marshall characteristics required in the special Lasbutag specifications. The stability required in the Lasbutag special specifications is met by using a modifier content of 4.2% to 6.8%, VIM can be achieved at different modifier levels between 4.8% and 7.2%, Cavity Parameters Between Mineral Aggregates (VMA) can be achieved using modifiers from 4% to 7.0% and Melt Value (Flux) can be achieved using modifiers from 4% to 6 .2%. The cold-mixed Lasbutag characteristics required in the Lasbutag special specifications can be met using a modifier between 4.8% and 6.2%, so the most ideal modifier is achieved at 5.5%.

Abstract

The durability of concrete can be determined from mixing coarse aggregate, fine aggregate, cement, water, with or without additives. The properties of concrete can be influenced by several things, such as the ratio of the mix, how to mix, how to transport, how to print, and how to compact. To analyze the compressive strength, flexural strength and split tensile strength of concrete submerged in sea water with variations in fineness modulus. The compressive strength results were 35.67Mpa, 31.63Mpa, 29.30Mpa respectively while the compressive strength of concrete with seawater immersion was 36.94Mpa, 36.52Mpa and 30.15Mpa. The split tensile strength results were 2.71Mpa, 2.65Mpa and 1.91MPa respectively, while the split tensile strength of concrete immersing in seawater with the same variations were 3.29MPa, 2.76MPa and 2.12MPa, respectively. The results of flexural strength were 4.22Mpa, 4.21Mpa, and 4.14MPa respectively, while the flexural strength of concrete with seawater immersion with the same variations were 4.27MPa, 4.22MPa, and 4.18MPa, respectively. The effect of fine grain modulus on compressive strength, split tensile strength and resulting flexural strength is very significant, the higher the fineness modulus of the coarse aggregate, the smaller the resulting value.

Abstract

Asbuton, a natural asphalt source on Buton Island in Southeast Sulawesi, is one of Indonesia's potential sources of natural wealth. As a road pavement material, LASBUTAG still has many weaknesses. This is especially true for cold LASBUTAG mixtures, which are only suitable for highways with light traffic. To mix Asbuton in cold conditions, a modifier is needed, the data of which is rare on the market, so other alternatives need to be considered as a modifier. In this research, we will try to use a mixture of waste oil and diesel as a modifier. The use of waste oil in this research is by looking at the development of the volume of waste oil. which continues to increase along with the increase in the number of motorized vehicles and motorized machines. The spread of oil waste is very widespread from big cities to rural areas throughout Indonesia. Waste from lubricating oil is included in B3 waste which needs special treatment in its processing. The aim of this research is to analyze the optimum asphalt content of cold Lasbutag mixtures with modifier materials from waste oil and diesel. From the results of this research, the Optimum Asphalt Content (KAO) in the Lasbutag Wearing Course (WC) mixture was 6.30% of the total mixture weight. Based on regression analysis, asphalt content can produce stability of 704.464 kg, flow of 3.078 mm, Vim of 4.467%, VMA of 17.077% and IKS of 78.763%. These values have met the requirements set out in the 2006 Special Lasbutag specifications.
