Abstract

The development of an area or region depends on the mobility of transportation facilities and infrastructure. This development is related to the increase in population and activities. These goods transport vehicles are also an indicator of the progress of an area which also drives the economic activities of its people. This research aims to see the magnitude of the influence of self-control in driving goods transportation. This research uses a quantitative descriptive type of research carried out in the Maminasata area which covers the Makassar City area, Regency. Takalar, Parts of Maros Regency and Parts of Gowa Regency. The results of the research show that the driver's self-control is in the moderate category or means that the driver is able to control himself while driving, such as controlling the speed and arranging the travel route to utilize travel time.

Abstract

Regional development is highly dependent on the effectiveness of transportation systems, particularly freight transport, which plays a strategic role in logistics distribution and economic growth. This study aims to describe the interest and behavior of freight vehicle drivers in the Mamminasata Metropolitan Area (Makassar, Gowa, Maros, Takalar), as well as to identify the factors influencing environmentally conscious driving behavior. A descriptive quantitative approach was employed through a survey of 200 drivers of trucks, containers, and heavy vehicles. The results show that drivers’ interest in driving safety is relatively high, while their economic interest falls into the moderate category, indicating a tendency to prioritize short-term income gains despite potential negative impacts on infrastructure and the environment. In terms of behavior, most drivers demonstrate moderate levels, with pre-trip and vehicle control behaviors rated as good, while shifting behavior, tactical behavior, and operational practices still require improvement. These findings highlight the importance of education and policy-based interventions to promote safe, efficient, and sustainable driving behavior, contributing to the development of environmentally friendly freight transport management in metropolitan areas.

Abstract

Indonesia’s mining sector, particularly in areas like Morowali Regency, Central Sulawesi, faces significant geotechnical challenges due to its location in the Pacific Ring of Fire. One of the key concerns in open-pit mining operations is slope instability, which can lead to landslides, threaten worker safety, damage infrastructure, and disrupt production. This study evaluates the slope stability in the Sambalagi site of PT. Wosindo Berkat Abadi using the Morgenstern-Price method, a limit equilibrium approach known for its accuracy in heterogeneous slope conditions. Field data were collected, including slope geometry, geological conditions, material strength, and hydrogeological factors. The safety factor (FK) was calculated based on geotechnical parameters such as cohesion, internal friction angle, and unit weight of the slope materials primarily saprolite and limonite. The actual slope FK value at PIT D was found to be 0.974, below the standard requirement (≥1.3) set by the Ministerial Decree No. 1827K/30/MEM/2018. To improve stability, a revised slope design was proposed, including reducing slope angles to 35°, increasing bench widths to 2 meters, and decreasing slope height per bench to 4 meters. The simulation of this revised geometry showed that it could achieve the required FK value. The study contributes to safer and more efficient mine planning by demonstrating the importance of integrating detailed geotechnical analysis in slope design, especially in tropical high-rainfall mining regions.

Abstract

The rapid growth of road infrastructure in Indonesia has increased the demand of construction materials and at the same time, intensified environmental issues. The study explores the potential application of nickel waste- which is a byproduct readily available to Indonesia in the smelting of nickel- as a partial replacement to coarse aggregate in porous asphalt mixtures. The research not only assesses the technical performance but also the environmental impact of the nickel waste substitution which can be regarded as a contribution to the literature on sustainable management of the construction process and the circular economy. Key parameters such as stability, flow, void content and the Marshall Quotient were tested in the laboratory and were evaluated as per the Bina Marga and SNI requirements. The results refer to the fact that nickel waste may meet a number of technical requirements, reaching an ideal concentration of asphalt into 5.5 0-100 that, at the same time, can provide waste minimization and possible cost-saving benefits. However, due to the fact that nickel slag contains heavy metals, it requires the use of strong environmental risk management, such as leaching control and stabilization technologies. These findings indicate that the use of nickel waste is more than a technical innovation; it is a strategic direction of the ability to become resource-efficient, symbiotic in the industrial industry, and to govern the operation of infrastructure in a sustainable manner. Placing industrial waste in a new category as productive input, this research sheds some light on how policy can be changed, how to innovate in procurements, and how government, industry, and academia can collaborate. The study concludes that the addition of nickel waste to the porous asphalt mixtures could help improve the performance of roads, reduce environmental ecological impacts, and promote the green infrastructure agenda in Indonesia, assuming that there are regulatory protections and a systematic environmental check-up.
