Abstract

An unsignalized intersection is the meeting point of several road approaches without traffic signal control. The vehicle control mechanism is implemented through traffic signs and priority rules. Problems arise when traffic volume increases. Vehicles will cross each other, so conflicts between vehicles are becoming more frequent. The unsignalized intersection on Jl. Dr. Sutomo is a four-leg intersection with traffic flow levels that continue to increase. The purpose of this study is to analyze the performance of the unsignalized intersection using the method of The Indonesian Road Capacity Guidelines (PKJI) 2023. Data collection was carried out through field surveys for three days. Observations were conducted during peak hours, namely in the morning from 07:00 to 09:00 WIB, at midday from 12:00 to 14:00 WIB, and in the afternoon from 16:00 to 18:00 WIB. The results show that the unsignalized intersection on Jl. Dr. Sutomo, Baturaja City, has a capacity of 3446 passenger car unit (PCU)/hour. The highest traffic flow occurred on Monday at 08:30–08:45 WIB at 2932 PCU/hour with a degree of saturation of 0.85. Vehicles experienced a travel delay of 94.52 seconds/PCU and the vehicle queue probability ranged from 29% to 57%. This condition places the intersection at Level of Service C. Vehicles are dominated by higher traffic flows on the major road, with stable movements. There is an increase in internal movement friction, which causes traffic density to be at a moderate level. This condition makes drivers experience difficulty in increasing speed and overtaking each other. Keywords: unsignalized intersection, degree of saturation, delay

Abstract

Sustainable clean water provision in post-disaster permanent housing (huntap) is a fundamental prerequisite for public health recovery and socio-economic restoration. However, comprehensive evaluations of operational management systems for water distribution from a socio-technical perspective remain scarce in disaster literature. Objective: This study analyzes the operational management system of clean water distribution in Huntap Talise, Palu City, following the 2018 multi-hazard disaster, examining infrastructure performance, user satisfaction, and institutional dynamics.  The research employed an explanatory sequential mixed-method design. Quantitative data were collected through surveys of 88 randomly selected households (Slovin formula, α=10%) and analyzed using the Relative Rank Index (RRI) and Spearman's Rho correlation test. Qualitative data were gathered through field observations, in-depth interviews, and focus group discussions, and were then analyzed thematically.  The study revealed dissonance between technical capacity and operational reality. The inflow discharge (22.22 L/sec) theoretically meets the total demand (520,500 L/day). However, RRI identified three critical deficiencies: 24-hour flow continuity (RRI=0.3045), speed of disturbance repair (RRI=0.3227), and disruption frequency (RRI=0.3295). Correlation analysis showed continuity strongly associated with reduced disruptions (r=0.581; p<0.001). Qualitatively, institutional pathologies emerged: ambiguous management status, lack of preventive maintenance, and a design that depends on limited household tank capacity. Conversely, voluntary contribution compliance reached 97%, indicating robust social capital.  This study confirms that post-disaster water system effectiveness is determined not solely by technical sufficiency, but by governance quality and institutional responsiveness. A socio-technical approach integrating institutional strengthening, operational professionalization, and the utilization of social capital is essential for achieving water system resilience in post-disaster permanent housing.  Keywords: Clean Water Distribution, Post-Disaster Permanent Housing, Operational Management, Community Satisfaction, Infrastructure Resilience, Socio-Technical Analysis
