Abstract

Rainfall is hydrology event that occurred seasonal in every year. There are two seasons occurred in Indonesia, dry season and rainy season. The analysis of rainfall characteristics plays a significant role to predict the rainfall occurrence and probability of flash flood. In this paper, rainfall analysis using Hydrognomon v.4.0 will provide hydrology data information, such as rainfall intensity and time series. The highest maximum rainfall of 526 mm (in 2010) has a return period of about 11 years. This means that rainfall of this magnitude can be expected to occur once every 11 years. The maximum rainfall of 425 mm (2013) has a return period of about 5.5 years, indicating a more frequent occurrence than the highest rainfall. Thus, it makes data trend rainfall with higher values tends to have longer return periods, indicating infrequent intensity. However, rainfall with lower intensity tends to have shorter return periods and occurring more frequently.

Abstract

Traffic safety is a critical concern on urban roads, including Jalan Mayjend Sungkono in Malang City, which experiences high accident rates. This study aims to analyze the influence of geometric road design and user behavior on traffic accidents from 2008 to 2020. Factors such as varying road widths, steep slopes, inadequate signage, and limited pedestrian facilities were identified as major contributors to traffic hazards. Additionally, risky driving behaviors and the dominance of motorcycles and private cars highlight safety challenges. The research employed a quantitative descriptive-analytical method. Primary data was collected through field surveys measuring geometric elements such as curve radius, superelevation, and grade. Secondary data on accident rates were sourced from police records. A polynomial regression analysis was conducted to determine the relationship between geometric factors and accident frequency. The coefficient of determination (R²) values for elements such as clear zones (57%), grade (50.04%), and superelevation (36%) indicated their significant impact on accident rates. Traffic patterns revealed peak hours during 6:00–9:00 AM and 4:00–7:00 PM, with weekend surges due to recreational activities. Results show that geometric improvements, particularly in clear zones and road grade, could substantially reduce accidents. Behavioral factors, such as speeding and abrupt stops by public transport, also exacerbate risks. Pedestrian safety remains a concern due to the lack of adequate crossings and sidewalks, especially near schools and markets. This study underscores the importance of integrated interventions involving road design enhancements and stricter traffic regulation enforcement to improve safety on Jalan Mayjend Sungkono.

Abstract

Rainfall is an essential component of climatology that should be consistently analyzed over extended periods. Availability of complete rainfall data is one of the most important parts in relation to Hydrology and Water Resources. The ideal data is  that in accordance with what is needed. However, in practice, incomplete records are often encountered, this can be caused by several things, including equipment damage, employee negligence, equipment replacement, and natural disaster. This situation causes certain parts of the time series data to contain empty data, it is necessary to pay attention to the pattern of the distribution of rain and the surrounding stations. In this paper, there are three rainfall stations analyzed, these are BBMKG Region I, Sampali station, and Belawan station. Unfortunately, there are two missing rainfall data in 2001 and 2006 in Belawan station. Therefore, this paper uses the Normal Ratio Method and the Inversed Square Distance Method to complete the rainfall data and compare the two methods. From the result, there are different values from the two methods, the value is smaller using the Normal Ratio Method. It can be caused by the influence of distance factors on inversed square distance.
