Abstract

Infrastructure development at PT Gunung Sejahtera Puti Pesona (GSPP), especially roads, has raised the potential for serious workplace accidents. To address this issue, a gabion retaining wall is planned as a preventive solution. The gabion project, designed as soil retention and a road safety barrier, aims to address core issues related to unsafe road conditions and slope landslides. This research provides a significant practical contribution to occupational safety in oil palm plantations, particularly in developing accident risk mitigation methods. Through comprehensive analysis of risk factors and the application of a more effective mitigation approach, this research aims to (1) create a gabion retaining wall model as a road safety barrier in the PT GSPP plantation using BIM software; (2) assess the road safety factors from the gabion model; and (3) determine the cost of work needed through a cost budget calculation. This study employs a quantitative method since the data to be processed consists of ratio data, with a primary focus on assessing the influence between the variables studied. The research produces a gabion design with dimensions of 2x1x1 meters, planned for installation along a 45-meter stretch of road with a slope height of 4 meters. The gabion modeling uses Revit 2023, based on Indonesian National Standards (SNI) 03-0090-1999 and the safety factor calculation (SNI) 03-2446-1991. The project’s Cost Budget Plan (RAB) indicates a total cost of IDR 615,444,891.00. This plan considers SNI standards to ensure road safety and minimize workplace accident risks. Implementing the gabion wall is expected to reduce the risk of dump trucks falling off slopes, thereby enhancing worker safety and ensuring smooth operations.

Abstract

Jalan Transyogi has a interweaving that connects Jalan Buperta with the Cibubur Toll Exit. At this weaving section, vehicles tend to slow down, further compounded by the presence of bus stops on the shoulder of the road, leading to conflicts and congestion. This study aims to analyze the causes of congestion and propose solutions to alleviate it on Jalan Transyog. This research employs a quantitative method, where data is collected through surveys on traffic volume, vehicle types, and speeds during peak and non-peak hours on weekdays, as well as secondary data as supporting information. The data is analyzed using PKJI 2023 and subsequently simulated using the VISSIM in 3D. The results of the analysis show that the ratio of interweaving for the Jalan Transyogi section is 0.48, meaning the link is still feasible. Based on the results of the single line capacity analysis of the influence of the presence of city buses, the degree of saturation (DJ) value was 1.014; travel speed (VT) is 18.62 km/hours, and travel time (WT) is 42 seconds. Calculations reveal that the arrival of one bus causes an additional 41 instances of slowing vehicles due to side friction. These values decreased to a degree of saturation (DJ) of 0.677; travel speed (VT) 21 km/hours; and the average travel time (WT) required is 36 seconds, after the best alternative solution is implemented by eliminating side obstacles and adjusting the operating hours of medium vehicles (KS) so as not to pass through Jalan Transyogi at peak hours, as well as creating a special lane for city buses. This alternative solution can last for 1 year, namely until 2025, and requires a review in the second year to ensure the feasibility requirements for a interweaving on the Jalan Transyogi are still met.

Abstract

Analysis of design flood discharge is required in waterworks planning, especially to determine the amount of design flood discharge in a watershed. The unit hydrograph method is a commonly used method in the calculation of design flood discharge, where this method requires rainfall data in its analysis. Current technology makes it possible to use satellite data as an alternative to data from rain gauge stations whose distribution is very limited. This research aims to obtain the level of suitability of the utilisation of satellite and measured rainfall data which will be used as a solution in predicting the design flood discharge. The rainfall data used in this study uses measured rainfall data from rain gauge stations and PERSIANN-CCS satellite rainfall data. The calculation results from both data will then be validated with the river flood discharge recorded at the Tukad Petanu Hulu Automatic Water Level Recorder (AWLR) Station and seen the level of conformity. This research shows that the design flood discharge in the Tukad Petanu watershed analysed using the Nakayasu Synthetic Unit Hydrograph based on measured rainfall data for 5, 10, 25, 50, and 100-year return periods is 58.16 m3/sec, 67.99 m3/sec, 82.76 m3/sec, 95.88 m3/sec, and 110.81 m3/sec, while based on PERSIANN-CCS satellite rainfall data for the same return period of 93.00 m3/sec, 101.12 m3/sec, 109.42 m3/sec, 113.98 m3/sec, and 117.65 m3/sec, respectively. The design flood discharge in the Tukad Petanu watershed based on measured discharge data at the Tukad Petanu Hulu AWLR Station is 15.75 m3/sec, 24.94 m3/sec, 42.47 m3/sec, 61.28 m3/sec, and 86.63 m3/sec for the same return period, respectively. The design flood discharge in the Tukad Petanu watershed analysed with the Nakayasu Synthetic Unit Hydrograph Method based on measured rainfall data has a better level of fit than the PERSIANN-CCS satellite rainfall data, where measured rainfall data provides lower VE, RE, and RMSE values when compared to PERSIANN-CCS satellite rainfall data.

Abstract

Land use changes and inappropriate land use in the Panasen watershed cause sedimentation in Lake Tondano. The influence of sediment-laden flow on the sedimentation process is still a problem that needs to be studied. The occurrence of flooding in the downstream part of the river due to the process of river silting is a problem that has an impact on economic losses, environmental problems and even unresolved social conflicts. This study aims to obtain the factors causing flooding by evaluating the capacity of the Panasen river cross-section in the downstream part and analyzing the influence of the Panasen River sediment flow on the sedimentation process in Lake Tondano. The study was conducted through field observations in the form of river geometry measurements and sediment flow sampling. Secondary data, namely topographic maps, rainfall data and measured discharge data were obtained from related agencies. Various analyses carried out were hydrological analysis, hydraulic analysis and sedimentation analysis. The hydrological analysis used maximum daily rainfall data obtained from the Noongan rainfall station and measured river discharge from the Noongan River AWLR. The magnitude of flood discharge using the HEC-HMS model with calibrated parameters for various return periods of 2, 5, 10, 25, 50 and 100 years were obtained at 50.2 m3/sec, 71.6 m3/sec, 82.1 m3/sec, 91.8 m3/sec, 97.2 m3/sec and 101.4 m3/sec. From the hydraulic analysis, it was obtained that under Q100 and lake tides, all river segments were unable to accommodate flood discharge. The flood water level (overflow) was at 1.2 - 3.1 meters and tended to occur towards the right river bank. The amount of sediment transport was determined after obtaining the dissolved sediment content, which was 6.16 gr/m3, resulted in an average increase in sediment volume to the lake for 30 years of 3,215,104.7 m³ or a thickness of 72.15 mm. The results of the study showed that the amount of sediment entering the lake was quite large, so that management efforts were needed in the Panasen River watershed, namely in the form of land conservation measures and determining appropriate land use.

Abstract

Gandusari - Kampak Road is a class II collector road and 2/2 TT Road Type with a length of 17 km located in Trenggalek Regency, the road is often used by the community to support the economy, tourism, politics, education and others. The large number of motorized vehicle activities has resulted in a decrease in service and quality on the road. The damage to the road disrupts traffic and road users, can be seen visually structural damage, such as surface defects, cracks and release of aggregate grains, so that an overlay is needed to increase structural value and prevent further damage. In this study, the 2017 Road Pavement Design Manual method was used to determine the thickness of the overlay by utilizing empirical data from deflection tests and condition analysis and integrating structural analysis based on traffic loads. This method is a technical guideline issued by the Ministry of PUPR. In the analysis of the thickness of the overlay, deflection data and traffic loads were used as determining variables for the thickness of the overlay. In this study, secondary data was used in the form of Benkelman Beam (BB) deflection and average daily traffic data obtained from the PUPR Office of Trenggalek Regency. Based on the analysis results, the CESA4 value is 4,281,450.00 ESA and CESA5 is 6,950,077.00 ESA. It can be concluded that the thickness of the overlay obtained during the 10-year design life based on the maximum deflection D0 of 0.419 mm produces an overlay thickness of 6 cm. If reviewed based on the deflection curve D200 of 0.248 mm, it produces an overlay thickness of 10 cm. From the results of traffic analysis and prevention of fatigue cracks before the design life, an overlay thickness of 10 cm was taken. This aims to increase the capacity of the structural performance and service life of the old pavement, so that the Gandusari - Kampak road can function safely and comfortably for users. This study focuses on sta 12 + 000 - sta 15 + 000 with an overlay of 10 cm.

Abstract

Landslide mitigation is a crucial effort in reducing the negative impacts of disaster, particulary ini high-risk aras such as South Balikpapan. This study aims to evaluate the awareness level of elementary school in South Balikpapan regarding landslide mitigation using a questionnaire covering three main aspects: understanding the causes of landslide, evacuation steps, and mitigation procedures. Data were collected from 578 students in grades 4-6 and analyzed descriptively. The result show that most students have a good understanding of the causes of landslide (70%), but only 35% of students understand the correct evacuation steps. Mitigation socialization is also lacking, with 73% of students stating they have never received formal socialization in school. This study recommends conducting regular disaster simulation and integrating mitigation materials into the curriculum to enhance student awareness. These findings provide strategic insight for educational institutions and stakeholders in landslide mitigation efforts.

Abstract

Landslides are the movement of soil structures and rock mixtures that move down lower areas around them. Indonesia is one of the countries with a high level of natural disasters, landslides. Balikpapan is one of the areas prone to natural disasters, especially landslides. This study aims to determine the extent of understanding of high school students in South Balikpapan regarding landslide disaster mitigation. The methodology of this study uses several methods, including document studies from relevant scientific journals as references and materials in formulating questions that will be entered into Google Form as a data collection tool. In this case, we chose high school students in South Balikpapan to be respondents regarding the knowledge of high school students in South Balikpapan regarding landslide disaster mitigation, considering that the Balikpapan area is a hilly area which is one of the factors causing landslide disasters. From the results of the research conducted, there are varying data regarding students' understanding of landslide disaster mitigation. The data obtained were 453 students from 4 schools in South Balikpapan. From the data it shows that there are 337 students who have received information or socialization about landslide prevention and 116 students have never received information or socialization about landslide prevention. The conclusion of the study shows that there are still some students who do not receive information or socialization about landslide disaster mitigation. This finding provides knowledge for educational institutions or related parties in efforts to mitigate landslide disasters.

Abstract

The Palasari Dam is a rock fill structure with a flood storage capacity of 10.37 million m³ and encompasses a catchment area of 40.75 km². In recent years, catastrophic climate changes have caused considerable variations between drought and intense rainfall, heightening the danger of dam failure owing to abrupt increases in water volume. This study is to assess the anticipated flood flow in the Palasari Watershed utilizing the Soil Conservation Service-Curve Number (SCS-CN) methodology within the HEC-HMS software. The utilized data include maximum annual rainfall from the CHIRPS satellite for the years 2004 to 2023, land use information retrieved from the Indonesia Geospatial Portal, and soil type data derived from HWSD v.2 (FAO). Simulations were performed for recurrence intervals of 5, 10, 25, 50, 100, and 1000 years, in addition to the Probable Maximum Flood (PMF). Validation indicates that the SCS approach in HEC-HMS yields greater flood discharge predictions than the Nakayasu method utilized in the 2018 Special Study of the Palasari Dam. The minimum discharge recorded at a 5-year return period was 64.60 m³/second, whilst the maximum discharge reached during the Probable Maximum Flood (PMF) was 710.70 m³/second. A notable discrepancy is evident in QPMF, with the SCS method documenting a discharge of 710.70 m³/second, surpassing the Nakayasu method's output of 686.07 m³/second. The SCS-CN method demonstrates a more conservative approach in calculating flood discharge, hence enhancing the safety margin in dam planning. Conversely, HEC-HMS offers advantages in assessing lag time and its integration with GIS, rendering it a more pragmatic method for water resource management in Indonesia. This research significantly enhances the formulation of Emergency Action Plans (EAP), especially in the context of dam failure analysis, aimed at mitigating risks associated with high flooding.
