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

Sustainable irrigation management plays a crucial role in supporting efficient and environmentally friendly agriculture. This study aims to identify the existing condition of the irrigation network, analyze the performance index of the tertiary irrigation system, and explain the concept of sustainable irrigation management in the Lamasi Irrigation Area. The study was conducted at Lamasi Dam, Batusitanduk Village, Walenrang Sub-district, Luwu Regency, using a quantitative descriptive approach. Secondary data were obtained from maps and irrigation network schemes of the Public Works Department of South Sulawesi Province, while primary data were collected through field surveys related to the physical condition of irrigation channels and structures. Performance analysis used irrigation performance index indicators and the ePAKSI application. The results showed a reliable discharge of 10 m³/second with 78 water user farmer associations. Irrigation performance was classified as good with a value of 84.83%, while the tertiary irrigation network condition index was 73.30% (moderate category) as found in this study, with a damage level of 21–40% requiring regular maintenance. The conclusion indicates the need for improved network maintenance and strengthening collaboration between stakeholders based on information technology.
