Abstract

Measuring sea surface height in open waters is very important for understanding tidal patterns and ocean wave dynamics. Most of the instruments currently used are based on pressure or acoustic sensors and are generally placed on the coast, making them less effective for measurements in open waters. This research develops a sea surface height measurement system based on the U-Blox NEO-8M GPS, which is placed on a buoy to obtain real-time elevation data. This system consists of an Arduino Mega 2560, a GPS U-Blox NEO-8M, and a Micro SD storage module. The measurement data were analyzed using the Fourier method to identify the main components constituting the sea surface height. The test results show a Mean Tide Level (MTL) of 4.27 m, a High-Water Level (HWL) of 11.30 m, and a Low Water Level (LWL) of -6.90 m. Fourier analysis revealed eight main components that make up the sea surface height pattern, with the dominant component having a wave period of 4.29 hours and an amplitude of 6 m. The comparison between the measured data and the Fourier model resulted in an average difference of 1.0798 m, likely caused by the influence of satellite signals, multipath, and atmospheric conditions. The results of this study indicate that the GPS NEO-8M can be used as an alternative for monitoring sea surface height in open waters, although it still requires accuracy improvement through signal correction techniques and more precise geoid references.

Abstract

Kotawaringin Barat Regency, Central Kalimantan Province, has six sub-districts, namely Kumai District, Arut Selatan District, Arut Utara District, Pangkalan Lada District, Pangkalan Banteng District, and Kotawaringin Lama District, all of which are areas prone to natural disasters. One of them is forest and land fires. In recent years, there have been many forest and land fires in the Kotawaringin Barat Regency area. Starting in 2022, there were around 75 forest and land fires; in 2023, there were around 201 incidents; and in 2024, there were around 36 incidents, all of which were in the Arut Selatan District and Kumai District. With the occurrence of forest and land fires, most of them in the two sub-districts, namely Kumai and Arut Selatan Districts, this study took the location of Arut Selatan District. The assessment of forest and land fire disaster risks uses spatial analysis methods. To find the weight of hazard, vulnerability, and capacity using secondary data processed with the formula according to the Regulation of the Head of BNPB Number 2 of 2012 concerning disaster risk assessment using the Excel application. The results of the assessment of the risk of forest and land fires in the South are dominated by high classifications of 9 villages/sub-districts with a percentage of 83.8% of the total area. While for the moderate classification of 5 villages/sub-districts with a percentage of 2.7% of the total area and moderate classification of 6 villages/sub-districts with a percentage of 13.5% of the total area. With the high risk of forest and land fires because the percentage of hazards and vulnerabilities is still high and the percentage of capacity is still classified as moderate. For this reason, it is necessary to increase capacity in dealing with forest and land fires to reduce the risk of forest and land fires that occur.

Abstract

This study developed a dynamic, web-based integrated spatial disaster profile database system that is highly vulnerable to various types of natural hazards, using Lebak Regency as a case study. The reference for each profile displayed is the Indonesian Disaster Risk (RBI). The output of this study is a web performance overview consisting of an interactive HTML-based frontend integrated with the backend spatial data management using MongoDB, Python, and JavaScript. This system provides district-level statistical summaries, visualizations with thematic classifications, and an automatic update feature via API simulation. In addition, this system integrates spatial and non-spatial data. Based on the evaluation, this system improves the effectiveness of data collection and utilization, supports evidence-based decision making, and strengthens cross-sector collaboration. The use of a non-relational database architecture optimized for dynamic spatial data with synchronous updates and web-based distribution is a major innovation with the hope of creating a standardized and adaptive disaster information system that can be replicated in other regions with similar risks.

Abstract

The Special Capital Region of Jakarta, located on the north coast of Java Island, is a low-lying sedimentary area crossed by 13 rivers, making it highly vulnerable to flooding from river overflows and sea level rise intensified by climate change. Flooding has been a persistent issue since the Dutch colonial era, driven by rapid urban growth, inadequate development management, the emergence of slums, and poor water resource management. Major floods occurred in 2002 and 2007, and annual floods continued until 2020. Several key factors contribute to flooding, including slope, rainfall, and land cover, while in West Jakarta the problem is further exacerbated by land subsidence and sea level rise. To address this, a flood vulnerability analysis was carried out using a GIS-based multi-criteria analysis approach. Unlike the BNPB reference, which considers only slope, rainfall, and land cover, this study incorporated six parameters: land cover, rainfall, drainage density, slope, land subsidence, and sea level rise. Each parameter was weighted based on its contribution to flooding risk, and spatial data were processed through overlay and reclassification to produce a flood vulnerability map. The results categorize West Jakarta into four classes: Not Vulnerable, Slightly Vulnerable, Vulnerable, and Highly Vulnerable. The majority of the area falls into Not Vulnerable (39.62%) and Slightly Vulnerable (36.30%), while only Kembangan District is dominated by the Highly Vulnerable category. Validation was conducted by comparing the vulnerability map with historical flood data from 2016 to 2023. The comparison shows a strong positive correlation between mapped vulnerability levels and the frequency of actual flood events. This alignment confirms the validity of the method and highlights its value for improving flood risk management and mitigation planning in West Jakarta.

Abstract

Coastal ecosystems and small-scale fisheries in Pengudang Village, Bintan, play an essential role in supporting local livelihoods. However, integrated spatial information on benthic habitats, mangroves, and fishing activities remains limited. This study aims to map coastal ecological conditions and fishing grounds while developing an accessible Web-GIS system to support coastal management. A descriptive qualitative approach was employed. Sentinel-2 Level 2A imagery was analyzed using Maximum Likelihood Classification, supported by field surveys, ground truthing, and interviews with 20 active fishers. Mangrove density was assessed using NDVI analysis. Spatial data, combined with fishers’ activity information, were integrated into a Web-GIS developed using the SDLC Waterfall method. The classification generated four dominant benthic habitat classes including seagrass, sand, mixed substrate, and dead coral with algae. NDVI indicated varying mangrove density levels from low to very high. Fishing grounds were concentrated in shallow waters with seagrass and mixed substrates. Fishers predominantly used kelong and bubu, producing 5–20 kg catch per trip. The developed Web-GIS provides interactive maps, layer selection, and spatial search features. The system enhances accessibility to coastal spatial data and supports evidence-based decision-making for sustainable coastal resource management in Pengudang Village.

Abstract

Detecting submarine cables in tropical shallow waters remains challenging due to environmental complexity and the similarity of backscatter signatures to other seafloor objects. This study characterizes the acoustic backscatter response of two types of submarine cables concrete-armored and non-armored in the waters of Tidung Island using a SIMRAD EK-15 and a Furuno FCV-628 echosounder operating at 200 kHz. Data processing was conducted to derive Volume Backscattering Strength (SVc) and Surface Scattering Strength (SS). Measurements of the concrete-armored cable using the Furuno system produced SVc values of −6.701 dB and −5.055 dB, and SS values of −11.855 dB and −9.510 dB, indicating high reflectivity due to the impedance contrast between concrete and seawater. In contrast, measurements of the non-armored cable using the SIMRAD system yielded SVc values of −11.547 dB and −12.600 dB and SS values of −14.612 dB and −15.665 dB, reflecting weaker and more variable returns caused by direct exposure of the cable structure to sediments and hydrodynamic forces. The consistent differences between the two cable types demonstrate that each structure exhibits a distinctive acoustic signature that can be used as a discriminating parameter for mapping. This study provides important empirical evidence by presenting direct acoustic backscatter characterization of submarine cables in Indonesia and demonstrates that commercial echosounders can reliably support infrastructure inspection in shallow-water environments.

Abstract

The challenge of significantly increasing waste generation is not exclusive to metropolitan areas but is also faced by small cities, including Biak Numfor Regency, particularly within the population centers of Biak Kota and Samofa Districts. This study employs Material Flow Analysis (MFA) to map waste flows and evaluate technological interventions based on primary sampling data referring to SNI 3964:2025. The analysis reveals a waste composition dominated by organics (41.25%) and plastics (26.18%). Simulation results indicate that Scenario II, deploying six units of Material Recovery Facilities (TPS 3R), effectively meets National Medium-Term Development Plan of the Republic of Indonesia (RPJMN) 2029. Furthermore, Scenario III, which integrates TPS 3R with a Refuse Derived Fuel (RDF)-based Integrated Waste Processing Site (TPST), successfully suppresses landfill residue to below 10%, aligning with the National Long-Term Development Plan of the Republic of Indonesia (RPJPN) 2045. It is concluded that the proposed integrated infrastructure is technically feasible for achieving national reduction mandates. However, practical implementation requires fundamental operational reforms, specifically rigorous source segregation and modernized collection logistics to maintain feedstock quality and facility performance.

Abstract

The increase in population, consumption, and technology use has led to a surge in electronic waste, a serious environmental issue. In Indonesia, e-waste management is still primarily handled by the informal sector, with limited regulation and technology, posing risks to the environment and public health. Gunung Anyar District was selected as the study area for this research to analyze household electronic waste flows and the role of the informal sector on urban mining, using Material Flow Analysis (MFA). Potential household e-waste generation was estimated through questionnaires and interviews with 100 households, while additional surveys of the informal sector, TPSSS B3 (Hazardous and Toxic Waste Storage and Management Facility), and waste banks were conducted to trace distribution pathways. Informal sector actors were surveyed using snowball sampling. The potential household e-waste generation in Gunung Anyar is 303.957,35 kg/year. Most e-waste is stored in homes or sold to collectors, with only a small fraction entering waste banks and TPSSS B3. Collectors, both dismantlers and non-dismantlers, act as key nodes in informal urban mining by channeling metal fractions to industries and other collectors, while generating substantial residues that end up at transfer stations and landfills. Although donations and repairs extend product lifespans, a large share of e-waste remains underutilized and environmentally hazardous. These findings highlight the need for stricter regulation and more structured systems to integrate informal actors and reduce environmental and public health impacts.

Abstract

Flash flood susceptibility in upstream watersheds is influenced not only by rainfall intensity but also by the spatial configuration of physiographic characteristics and land use. The Banyuputih Watershed in East Java has experienced recurrent flash floods, emphasizing the need for spatial assessment to support effective mitigation planning. This study develops a flash flood susceptibility map using a GIS-based multi-criteria approach integrated with logistic regression. The analyzed factors include DEM-derived topographic parameters (elevation, slope, Topographic Position Index (TPI), Topographic Wetness Index (TWI), and plan curvature), Hydrologic Soil Group (HSG), rainfall, river density, land cover, and NDVI. The relative influence of each factor was determined from logistic regression coefficients. The results classify the watershed into five susceptibility levels: very low, low, moderate, high, and very high. High to very high susceptibility zones are spatially limited and mainly concentrated in upstream and parts of midstream areas characterized by flow-convergent topography and less protective land cover. Most of the watershed is dominated by very low to moderate vulnerability, indicating that flash flood potential is spatially localized. The resulting map provides a scientific basis for watershed management, land-use planning, and targeted nature-based mitigation strategies.

Abstract

The Semajid River Basin (DAS) faces complex environmental problems, including flooding during the rainy season, drought during the dry season, increased river sedimentation, and uncontrolled land use changes. This study aims to assess the performance of the Semajid Watershed in accordance with the Minister of Forestry Regulation Number 61 of 2014 on Monitoring and Evaluation of Watershed Performance, and to formulate strategies to improve watershed performance through land-cover optimization scenarios. The watershed performance assessment includes criteria for land, water management, socio-economics, building investment value, and space utilization. The evaluation results show that the Semajid Watershed performance value is 113.75, which indicates that the watershed is in the category of needing to be saved. The application of the additional land cover scenario has a significant impact on improving the criteria for vegetation cover and protected areas. The Percentage of Permanent Vegetation Cover (PPV) increased from 5.5% (very high recovery category) to 32.44% (low recovery category), while the value of the protected area criteria decreased from 68.64 to 9.37, indicating an improvement in the ecological condition of the watershed. Although the watershed's carrying capacity increased to 107.5, the Semajid watershed remains in need of restoration. Therefore, restoration of the Semajid watershed requires integrated management that sustainably integrates technical and non-technical efforts.
