Abstract

Landslide is a natural phenomenon that occurs when the movement of soil and rock on a slope takes place due to the influence of gravity, so that the material moves towards the surrounding lower area. In Indonesia, the incidence of landslides is quite high, and Balikpapan is one of the areas vulnerable to this disaster. This study aims to assess the understanding of high school students in Central Balikpapan regarding landslide disaster mitigation. To achieve this goal, the method used in this research is documentation study from various scientific journals to develop questions which are then distributed through Google Form as a database. The targeted respondents are high school and vocational school students in Central Balikpapan area. The results show that 97.20% of the students know the causes and characteristics of landslides, while the other 2.80% still do not know the causes and characteristics of landslides. These findings provide valuable insights for related institutions in landslide disaster mitigation efforts.

Abstract

Landslides are one of the most common natural disasters in Indonesia and can occur in almost all parts of the country, including in East Kalimantan, especially in Balikpapan City. The region is highly vulnerable to landslides, especially during the very heavy rainy season. This is due to the geographical conditions predisposing to landslides as well as high rainfall, which worsens soil stability. With the high potential risk of landslides, it is important to increase the awareness and understanding of the community, particularly the younger generation, on mitigation measures that can be taken to reduce the impact of this disaster. This research makes use of questionnaire distribution as a tool to analyse the level of awareness and understanding of SMA and SMK students in North Balikpapan regarding landslide mitigation. This approach provides a clearer picture of the extent to which students understand the causes, impacts, and mitigation measures that can be taken in dealing with landslides. The results of this study show that most of the students, 73.50%, agree that they know the main causes of landslides. This indicates that the majority of students have received information about the factors that cause landslides, such as heavy rain, erosion, or human activities that destroy vegetation. However, although this figure is quite high, there are still 26.50% of students who disagree or feel that they do not understand the main causes of this disaster, which reflects a lack of information or awareness among some students. In addition, the majority of SMA and SMK students in North Balikpapan have a good understanding of landslides, including their impacts and mitigation measures after disasters. Nevertheless, there are still a small number of respondents who do not fully understand some important concepts related to landslides, such as the mitigation steps that need to be taken before, during and after a disaster occurs. These findings provide useful insights for relevant parties, especially for schools and educational institutions, to continue improving socialisation and education on landslide mitigation.

Abstract

Landslide is the process of moving rock mass (soil) due to gravity. Landslide occurs due to disturbance of equilibrium of forces acting on the slope, i.e. retaining force and launching force. Balikpapan City has a slope between 15-40%, with an area of 21,305.57 hectares or 42.33% of the total area.  Balikpapan City is classified as an area that rarely experiences landslides. However, several landslide incidents have been reported, so people are encouraged to remain vigilant and take preventive measures.  The aim of this study is to focus on the potential landslide hazard in Balikpapan City and how to mitigate it. Because Balikpapan city has hilly contours with soil types that are easily eroded. The method used in this research is the distribution of questionnaires distributed using Google Form link and sent to 7 schools in Balikpapan city.  Data collection started on 6 November 2024.  The results of this data collection activity include 7 high school/vocational school and Madrasah located in Balikpapan City with a total of 490 respondents, by being given 10 questions containing landslide disaster, it is found that the results of ‘agree’ get the most results in the answers of high school students with an average of 90% each school. With this it can be said that students of SMK and Madrasah know and understand about landslides and are familiar with the causes and impacts of landslides. The contribution given in this research includes a number of crucial steps to improve the understanding and awareness of SMA and SMK students in Balikpapan City about landslide disaster. With these contributions, the research is expected to have a positive effect on increasing the awareness and knowledge of SMA and SMK students in Balikpapan City on the importance of landslide disaster mitigation. The findings provide valuable insights for relevant institutions in addressing landslide disaster mitigation efforts.

Abstract

Infrastructure, Facilities, and Public Utilities (PSU) are physical facilities that play a crucial role in creating a healthy, safe, and affordable residential environment. One of the main aspects of PSU is the construction of neighborhood roads in residential and settlement areas. Risk management is essential to ensuring project success by identifying and mitigating potential risks that may hinder PSU road construction. This study aims to analyze and manage risks in PSU road projects in North Sulawesi using the Severity Index (SI) and Root Cause Analysis (RCA) methods, implementing the analysis with Python, and developing mitigation strategies. Data were collected through interviews and questionnaires with contractors, Commitment Making Officials (PPK), field directors, and project supervisors. To ensure data reliability, each risk variable was tested for relevance before further analysis. The SI method was used to prioritize risks based on their impact, while the RCA method identified the root causes of dominant risks. Python was applied to automate the Severity Index analysis, facilitate the RCA 5 Whys process, and visualize data to enhance efficiency and accuracy. The SI analysis identified 11 dominant risks out of 28, covering natural, material and personnel, cost and time, and environmental risks. Key risks included unpredictable weather, design changes in the field, and project delays. The root causes included a lack of consideration for weather factors, insufficient technical personnel, and ineffective communication. The proposed mitigation strategies include developing contingency plans, increasing technical personnel, and improving coordination among stakeholders. This study helps PSU road construction users and service providers identify, understand, and respond to risks more effectively while also providing Python as a risk management tool to automate risk identification and analysis using the SI and RCA methods for future applications.

Abstract

Flood disasters are one of the major issues frequently occurring in Manado City, Indonesia, particularly during the rainy season. These floods are influenced by various factors, including changes in land use, deforestation in upstream river areas, river sedimentation, inadequate drainage systems, and extreme rainfall. Climate change also significantly impacts the hydrological cycle, including the intensity, frequency, and distribution of rainfall. Manado City is highly vulnerable to increased rainfall intensity, especially during specific months. Therefore, analyzing rainfall pattern changes over the past 50 years is crucial for a deeper understanding of their impacts. This study aims to identify trends in rainfall pattern changes in the Manado region and its surroundings over the last 50 years. The analysis focuses on several variables, including annual average rainfall, maximum daily rainfall, the number of rainy days per year, months with maximum daily rainfall, and average monthly rainfall. Rainfall data were obtained from three observation stations: Sam Ratulangi Meteorological Station, North Sulawesi Climatology Station, and Bitung Maritime Meteorological Station. Statistical analysis was conducted using linear regression and the Mann-Kendall Trend method to determine data trends. The analysis results indicate that the annual average rainfall trend has increased at all observation stations. Maximum daily rainfall shows a significant increasing trend at North Sulawesi Climatology Station, while the increases at the other two stations are not significant. The number of rainy days per year also shows an increasing trend at all stations, though not significantly. The distribution of maximum daily rainfall frequency tends to occur at the beginning of the year (January) and the end of the year (December), with decreasing frequency in the following months until mid-year. This distribution pattern forms a "U" or "V" shape at Sam Ratulangi Meteorological Station and North Sulawesi Climatology Station, whereas at Bitung Maritime Meteorological Station, rainfall patterns are more evenly distributed throughout the year. Additionally, average monthly rainfall shows an increasing linear trend in almost all months at all observation stations. This study contributes to the understanding of rainfall pattern changes, which can serve as a basis for spatial planning, disaster mitigation, and the adaptive design of infrastructure to cope with climate change in urban areas such as Manado.

Abstract

Buildings or structures in Indonesia are highly vulnerable to earthquakes, especially in seismic zone 5. Podium-type buildings consist of two main parts: the podium and the tower. This type of building is used due to its advantages of better stability, resulting from a wider base, efficient land use, and good seismic performance. Therefore, this study aims to analyze the structural behavior of three types of buildings: non-podium structures, centrically supported podium towers, and eccentrically supported podium towers. The analysis is conducted using the response spectrum analysis method to examine various structural behaviors, including comparisons of base shear forces, inter-story drift, and the P-Delta effect. The analysis results show that the base shear force of the non-podium structure is 18,463.26 kN, which is higher than that of the centrically supported podium tower at 10,661 kN and the eccentrically supported podium tower at 10,661 kN. In terms of inter-story drift in the x-direction, the eccentrically supported podium tower (model 3) has a displacement of 64.405 mm, exceeding the permissible limit of 61.538 mm. Meanwhile, the non-podium structure (model 1) has a displacement of 60.658 mm, and the centrically supported podium tower (model 2) has 56.408 mm, both meeting the permissible drift limits. For the maximum P-Delta values, Model 1 is 0.0964, Model 2 is 0.05844, and Model 3 is 0.0722, all of which comply with the P-Delta effect limits. The findings of this study are expected to provide a deeper understanding of the differences in structural performance between non-podium structures, centrically supported podium towers, and eccentrically supported podium towers, which can be used as a reference for designers in selecting a structurally safe system by increasing stability against lateral loads.

Abstract

Road functionality is a critical factor affecting the safety and smooth mobility of road users. To ensure that roads meet technical requirements, an evaluation of road functionality is conducted to assess their condition and identify necessary improvements for safe and comfortable operation. This study aims to evaluate the road functionality of the Lamongan – Gedeg boundary road segment from km 26+290 to km 44+470 using the star rating method based on the Technical Guidelines for Road Functionality No. 06/P/BM/2024. This road segment is a class II collector road with provincial road status and a primary road network system, playing a crucial role in supporting mobility between regions in the Mojokerto area. The research method is descriptive qualitative, involving field surveys and the completion of star rating assessment forms for each 18.18 km road segment divided into 182 sections. The assessment results show an average star rating score of 5.10, corresponding to a star category of 3 («««). Out of all evaluated segments, there are 18 segments in category 5 stars, 111 segments in 4 stars, 45 segments in 3 stars, and 8 segments in 2 stars. Segments with 2- and 3-star ratings indicate the need for technical interventions to improve road safety. Recommendations for improvement include addressing eight common damage types, such as marking repairs, adding signage, resurfacing, and installing guardrails and delineators. As part of the implementation, a Detailed Engineering Design (DED) and Budget Plan (RAB) were developed amounting to IDR 1,542,089,883.00. The findings of this study are expected to serve as technical references for local governments and stakeholders in planning road safety improvements and as a scientific basis for road functionality evaluation.

Abstract

The rapid population growth in Klungkung Regency, accompanied by an increase in motor vehicle ownership, has accelerated the development of transportation in the region. Although traffic density in Klungkung is lower than that in larger cities, traffic accidents continue to occur. Therefore, identifying accident-prone areas and the contributing factors is essential. This study aims to analyze black sites and black spots, as well as to identify the factors influencing traffic accidents in Klungkung Regency. The research utilizes secondary data obtained from the Klungkung Police Department. The analysis begins with problem identification, data collection, and the application of Z-Score and Accident Equivalent Number (AEK) methods to identify black sites. Black spots are identified using the Upper Control Limit (UCL) method, followed by an analysis of accident-contributing factors. The findings reveal that 79.3% of accidents involve motorcycles, with an estimated economic loss of IDR 646,725,000. The dominant type of accident (44.71%) is loss of vehicle control, while 23% of incidents occur on Sundays, and 32.23% of the offenders are between 16 and 25 years old. Four black sites were identified: Prof. Dr. Ida Bagus Mantra Road, Raya Sampalan Road, Ngurah Rai Road, and Raya Klumbu Tokah Pakeh Road. In addition, six black spots were found: STA 0+000–0+500, STA 2+000–2+500, STA 3+000–3+500, STA 4+000–4+500, STA 5+000–5+500, and STA 7+000–7+500. Contributing human factors include careless behavior, drowsiness, sudden braking, and mobile phone use while driving. Vehicle-related causes involve brake failure, faulty lights, worn tires, and missing mirrors. Accidents are more likely to occur under clear weather conditions due to a reduced perception of risk, which can lead drivers to lower their vigilance and violate traffic regulations. This study offers an integrated analytical approach to identifying black sites and black spots while examining key accident factors. The findings are expected to support targeted strategies and serve as a reference for policymakers and traffic safety authorities in developing more effective prevention measures.

Abstract

Concrete is the most commonly used primary construction material, so increasing demand for raw materials can encourage continuous mining of coarse aggregates, which risks causing natural resource scarcity and environmental damage such as landslides. Thus, alternative materials are needed that are still rarely used but according to applicable standards. Based on this, the author took the initiative to utilize concrete waste as a substitute for coarse aggregate in making new concrete. The concrete waste used comes from ready mix test objects of PT X located in Surabaya, which produces around 8m³ of test object waste that is disposed of every month. The contribution in this study is to reduce concrete waste that pollutes the environment and evaluate whether concrete waste with similar quality can exceed the compressive strength of normal concrete. Therefore, this study aims to analyze the utilization of ready-mix concrete waste stone from PT X located in Surabaya as a substitute material for coarse aggregate in concrete mixtures with a focus on its effect on compressive strength. This study uses a quantitative method through laboratory testing with cylindrical concrete samples with a diameter of 15 cm and a height of 30 cm, totaling 36 samples. These samples will be used for concrete compressive strength tests at the ages of 7, 14, and 28 days. There are two substitution variations, namely 0% and 100%, and two planned qualities, namely Fc 25 MPa for a mixture with K-300 quality concrete waste substitution, and Fc 30 MPa for a mixture with K-400 quality concrete waste substitution. The optimum compressive strength value for the design quality f'c 25 was obtained at 21.26 MPa with 0% coarse aggregate substitution, which is 4.78% higher than 100% coarse aggregate substitution. Meanwhile, for the design quality f'c 30, the optimum value was recorded at 24.59 MPa with 0% coarse aggregate substitution, which is 10.9% higher than 100% coarse aggregate substitution. These results indicate that the compressive strength obtained has not been able to achieve the planned compressive strength target and also the use of concrete waste stone as a substitute for coarse aggregate is highly discouraged.

Abstract

This study was motivated by the high volume of traffic passing through the intersection of Jalan Garuda - Jalan Rajawali - Jalan Raya Betro, which has the potential to cause congestion and reduce the performance of the intersection. The objectives of the study were to analyze the highest number of vehicles crossing the intersection each day, evaluate the performance of the intersection when given a traffic signal (APILL), and determine the appropriate alternative improvements to reduce congestion at that location. The method used is the Pedoman Kapasitas Jalan Indonesia manual (PKJI) 2023 to measure capacity (C), degree of saturation (DJ), delay (T), and queue opportunitie (PA). The results of the analysis show that the highest traffic volume occurred on Thursday, February 20, 2025, at 15:00-16:00 WIB with a total of 2,016 smp/hour, resulting in a capacity (C) of 2,209 smp/hour with a degree of saturation (DJ) of 0.91 and a delay (T) 16 seconds/hour and queue opportunitie (PA) upper limits at 66% and lower limit at 33% so that the level of service (LOS) is in category E, which means unstable motion, stalled vehicles. Then after applying the APILL signal it is estimated that it can increase the capacity (C) 3520 smp/hour, with the degree of saturation (DJ) being 0.75, and the average delay (T) decreasing to 7.52 seconds/hour, and shortening the queue length (PA) to 33 meters so that the level of service (LOS) is in category D. The contribution of this research is to provide valid and data-driven recommendations for intersec
