A Systematic Review of Participatory Approaches in Flood Risk Management: Methods and Applications
Get PDFFlood risk management (FRM) increasingly integrates participatory approaches to enhance resilience and effectiveness by engaging local communities and stakeholders. This systematic review synthesizes findings from 22 peer-reviewed articles published between 2015 and 2024, highlighting the tools, stakeholders, levels of participation, outcomes, and challenges associated with participatory FRM. The review identifies key engagement tools such as participatory mapping, community workshops, and digital platforms, noting their varied effectiveness in different contexts. Stakeholder involvement spans residents, government agencies, and NGOs, with diverse contributions enhancing the contextual relevance and acceptance of FRM strategies. Levels of participation range from consultative to collaborative and fully empowering, with higher engagement linked to more resilient and adaptive outcomes, albeit requiring more resources and time. Outcomes demonstrate that participatory approaches improve community preparedness, enhance flood management plans, and integrate local knowledge effectively. However, challenges persist, including resource constraints, stakeholder conflicts, and communication barriers, necessitating adaptive management and innovative engagement strategies. The findings underscore the need for policymakers and practitioners to prioritize participatory methods to develop inclusive and robust FRM frameworks. Future research should focus on scalable participatory models, the integration of advanced technologies, and the evaluation of long-term impacts on community resilience, providing a roadmap for the enhanced application of participatory approaches in diverse contexts
Pengaruh Penyelenggaraan Major Greening Event “Kampung Surabaya Hebat” terhadap Pembangunan Multidimensi Kota Surabaya
Get PDFPenyelenggaraan event kota pada skala besar maupun kecil (Giga-Mega-Major event) berpotensi menjadi solusi inovatif untuk mengatasi permasalahan perkotaan seperti kemiskinan, kekumuhan, dan ketimpangan infrastruktur, serta menjadi instrumen untuk meningkatkan kualitas perencanaan kota dan kesejahteraan masyarakat dengan memaksimalkan potensi pembangunan di segala aspek. Pengaruh event dapat ditingkatkan dengan memahami tujuan event, skala, kondisi kebutuhan kota, serta dampaknya di masa depan. Penelitian yang ada cenderung berfokus pada percepatan kontribusi sosial-ekonomi melalui penyelenggaraan event skala besar seperti Pertandingan Olimpiade, Piala Dunia FIFA atau World Expo. Event lokal juga dapat memberikan pengaruh transformasi secara berkelanjutan. Namun, hingga kini, pengaruh tersebut belum tereksplorasi. Penelitian ini berupaya memahami kontribusi major greening event Kampung Surabaya Hebat (KSH) sebagai even lokal terhadap pembangunan Kota Surabaya. Penelitian ini dilakukan dengan menganalisis 94 kampung dari 31 kecamatan di Kota Surabaya, menggunakan variabel pengukuran pengaruh event yang komprehensif serta melibatkan beragam pihak. Data yang diperoleh diolah dengan pendekatan metode campuran, diawali dengan Multivariate Analysis – Structural Equation Model (SEM – PLS) untuk mengetahui kontribusi dalam variabel event, dengan event sebagai variabel mediasi. Kemudian, Content Analysis dilakukan untuk mengungkap pengaruh KSH terhadap pembangunan Kota Surabaya. Hasil penelitian menunjukkan bahwa KSH mempengaruhi pembangunan multidimensi Kota Surabaya, baik secara langsung maupun tidak langsung, sebagai salah satu sub kegiatan pembangunan yang memfasilitasi keterlibatan berbagai aktor. Model konstruk KSH yang terbentuk menjelaskan kontribusi KSH terhadap pembangunan Kota Surabaya. KSH berpengaruh secara positif terhadap pertumbuhan ekonomi sektor informal, serta mendorong modal sosial dan menumbuhkan kesadaran dan kepedulian masyarakat terhadap kegiatan pembangunan. Selain itu, KSH juga turut mengubah citra dan kondisi lingkungan perkampungan, serta membantu memastikan keberlanjutan program pembangunan di masyarakat
Vertical Axis Wind Turbine-Flettner Rotor Integration as Hybrid Propulsion Power on a Model Ship
Get PDFNatural energy is something that can be utilized as an alternative energy besides fossil fuel energy. Considering that the need for fossil fuel energy is decreasing, the purpose of this research is to propose a utilization of natural energy in the form of wind. The implication of the use of this alternative energy in the hybrid power function is that the integration of vertical axis wind turbines and Flettner rotors is chosen as the main driving energy of the model ship that fully utilizes wind energy. The performance evaluation stages in this experiment include design and simulation for the turbine-Flettner rotor, and trials on a model ship using a monohull type hull. The objective of this research is to obtain the optimum performance of the combined vertical-axis wind turbine-Fletner rotor in supporting hybrid propulsion power on a model ship. The power required by Flettner is 0.695 Watt and the turbine rotate at a minimum angular velocity of 40 rpm. The highest contribution of the Flettner rotor at ship service speed 1 knot and ship total resistance of 0.01 kN reached 26,20%
Performance of Split Air Conditioner with Capillary Pipe Variations with R32 Refrigerant on Ships
Get PDFThe hot temperature on the ship will interfere with the comfort of the crew, so an air conditioning machine is needed to cool down. Hot conditions make air conditioning needed on the ship as a means of cooling when the ship sails. Split AC performance is very necessary so that the temperature released remains optimal. Split air conditioners have many components, for example, capillary pipes, capillary pipes play a very important role in obtaining low temperatures. Therefore, it is necessary to research variations in the length and diameter of capillary pipes. As a pressure-lowering device and regulating the amount of refrigerant liquid flowing, the length and diameter of capillary pipes greatly affect the cooling process. If you find the right and right variation, you will get a temperature lower than the standard Therefore, to get extra cooling for split air conditioners, research is proposed on the effect of variations in the length of capillary pipes on the work performance of split air conditioner machines using R32 refrigerant for ship accommodation room. To know the effect of cooling more extra because with changes in capillary pipes further maximize cold temperatures by using additional capillary pipe length. This study uses an experimental method with a split air conditioner 0.5 Hp as the main object and variations in capillary pipe length. the temperature after the capillary pipe is varied is lower than the standard, namely the standard achievement of 55.9 for a variation of 72 cm, which is 26.4, and the last variation of 159 cm, which is 29
Failure Tree Analysis of CNC Plasma Cutting Machine for Occupational Safety on Shipyard
Get PDFThe advancement of ship production technology in Indonesia involves the implementation of modern techniques integrating computer-based design and production facilities, such as Computer-Aided Manufacturing (CAM) for operating production machines utilizing Computer Numerical Control (CNC). One specific type of CNC machine utilized in ship production is the plasma cutting CNC machine. Despite being crucial to production, these machines frequently encounter failures that impede the production process. Through prior failure analyses conducted by the company, it has been identified that the dust collector air hose component exhibits the highest failure rate with six distinct failure modes. This article conducts qualitative and quantitative analyses of the causes of failure in the air hose dust collector of CNC plasma cutting machines using the Fault Tree Analysis (FTA) method. FTA is employed as a method to ascertain the fundamental causes of the event. The analysis results are utilized to provide recommendations for controlling objectives related to occupational safety. Six failure trees are generated, comprising a total of 28 basic causes. The most frequently occurring types of basic causes are associated with workers, methods, and materials. The probability of occurrence for the minimal cut set of each failure tree has been successfully computed. These calculations reveal that all top events possess probability values exceeding 76%. Specifically, the event of the dust collector air gap breaking has the highest probability value, reaching 99.88%, which is a composite of 15 basic causes. Control recommendations are provided in the form of substitution, engineering solutions, and administrative controls
