Abstract

The continuous operation of airlock machines in wheat milling facilities plays a critical role in the material handling system, especially in the transfer of grain from ships to silo storage. At PT XYZ, the airlock machine has been identified as the equipment with the highest frequency of downtime over a three-month observation period, leading to significant disruptions in production flow and increased corrective maintenance costs. This study aims to analyze the failure modes of the airlock machine using the Failure Mode and Effect Analysis (FMEA) method and to develop preventive maintenance recommendations based on the highest Risk Priority Number (RPN) values. The research adopts a quantitative descriptive approach, involving field observations, interviews with maintenance personnel, historical breakdown analysis, and machine technical documentation review. The FMEA results indicate that the seal, gear, and bearing are the most critical components, with RPN values of 224, 210, and 192, respectively. These components are prioritized for preventive actions such as regular seal replacement, scheduled lubrication, gear inspections, and motor monitoring. Simulation of the proposed maintenance strategy demonstrates a 66.7% reduction in downtime, from 18 hours to 6 hours per month, and a 43.7% reduction in total maintenance costs, from Rp 9,034,500 to Rp 5,087,500 monthly. These results validate the effectiveness of the FMEA method in identifying risk-prone components and optimizing maintenance planning. It is recommended that PT XYZ institutionalize periodic FMEA updates and establish a cross-functional analysis team to continuously monitor and improve equipment reliability.

Abstract

This study aims to analyze the performance and conduct reverse engineering of the Francis Turbine runner at the Tanggari 1 Hydroelectric Power Plant (PLTA Tanggari 1) through 3D scanning and Computational Fluid Dynamics (CFD) simulation. The main objective is to evaluate the turbine's efficiency and identify areas for improvement in the runner geometry. Data from the 3D scan are used to reconstruct a CAD model, which is then numerically tested to predict hydraulic performance. CFD simulations are carried out under various guide vane openings and head variations. The simulation results show a maximum efficiency of 93% at a head of 122.4 meters with a guide vane opening angle of 26° and a flow rate of 8.5 m³/s. The resulting performance curve and hill chart indicate the optimal operating point or Best Efficiency Point (BEP), which serves as a critical reference for turbine operation settings. Flow phenomena such as separation and vortex formation were detected under off-BEP operating conditions, potentially causing pressure fluctuations and vibrations. As a technical recommendation, it is advised to operate the turbine close to the BEP to minimize vibrations and energy losses. Furthermore, the runner geometry obtained from reverse engineering can serve as a basis for component refabrication and the development of new runner designs that are more adaptive to varying load conditions.

Abstract

This study presents an evaluation of the cooling load capacity in the departure apron corridor area at Supadio International Airport using the Cooling Load Temperature Difference (CLTD) method. The objective of the research is to assess whether the current air conditioning (AC) is adequate to meet thermal comfort requirements in a tropical climate characterized by high humidity and strong solar radiation. A detailed field survey was conducted at Gate 3, a glass-dominated corridor that experiences significant heat gain from solar exposure. Empirical data including temperature profiles, material properties, occupancy levels, and equipment specifications were collected over a two-week period using digital instruments. Using the CLTD method, the heat contributions from walls, roof, glass surfaces, occupants, lighting, and air infiltration were quantified. The results revealed that the installed AC (2 PK) only delivers about  of the required cooling load, with the total load estimated at 66,448 BTU/hr. The dominant sources of thermal gain include the roof and east-facing glass panels. The study recommends AC resizing, glass shading implementation, and improved insulation to enhance energy efficiency. This research contributes practical insights for HVAC optimization in airport infrastructure within hot-humid climates.

Abstract

Slums are one of the biggest challenges in sustainable urban development. In the midst of the government's efforts to run a program to handle slum organizations, the issue of miscarriage after physical intervention often goes unnoticed. This study aims to stop the slum management program in Tegal Sari Mandala II Village, with a Mixed Methods approach that combines linear multiple quantitative regression analysis and a qualitative descriptive approach.The results show that community participation has a significant effect on poverty programs, while infra-structure quality has not shown a statistically strong relationship. Qualitative findings support these results, where residents feel more attached to the programs they have followed in the past. Meanwhile, a number of infrastructures that are not in accordance with needs are considered less effective in supporting sustainability. This study concludes that the desire of the program is not only determined by technical aspects, but also by social, institutional, and cultural factors that are intertwined. Strategic recommendations include strengthening participation, improving design based on local needs, and integration with spatial policies.

Abstract

The existence of Final Waste Processing Sites (TPA) in urban areas often presents a dilemma between the need for waste management infrastructure and its environmental and social impacts on surrounding communities. This study aims to examine the impact of the TPA Terjun in Medan City on patterns of land use change and the socioeconomic conditions of nearby residents. The method used is quantitative, involving a survey of 150 respondents, and multiple linear regression analysis to test the influence of two independent variables namely, the characteristics of the TPA and public perception and response on community perceptions of environmental impacts. The results indicate that both independent variables have a significant simultaneous effect on public perception, with a model significance value of 0.022. Partially, the physical characteristics of the TPA have a significantly positive influence, while community perceptions and responses also contribute meaningfully. However, the low coefficient of determination (R² = 0.009) suggests that many other factors outside the model also influence perceptions of environmental impact. This study highlights the importance of a holistic approach in spatial planning and urban environmental management, particularly in relation to public facilities such as TPAs. Community participation, infrastructure quality, and zoning certainty are crucial factors in maintaining the balance between the functional needs of the city and the desired quality of the microenvironment.

Abstract

Slum settlements developing around Final Disposal Sites (TPA) represent a complex phenomenon that affects the quality of the urban living environment. In Karo Regency, the proximity of the TPA to residential areas has raised various issues such as air pollution, declining sanitation quality, and limited community participation in spatial planning processes. This study aims to analyze the influence of Distance to the TPA (X1), Length of Residence (X2), Community Participation (X3), Perception of TPA Impact (X4), and Household Income (X5) on the Quality of Slum Settlements (Y). A quantitative approach was applied using a multiple linear regression model, based on primary data from 200 respondents residing in areas affected by the TPA. The analysis revealed that, simultaneously, the four independent variables (X1–X4) significantly influence settlement quality, whereas household income does not show a significant effect. Partially, Distance to the TPA and Length of Residence have negative effects, while Perception of TPA Impact has a positive effect. Interestingly, Community Participation shows a negative influence, indicating ineffective engagement in environmental management. The R² value of 0.016 suggests that the model explains only a small portion of the variation, yet the F-test significance supports the overall model's relevance. Recommendations from this study include the importance of establishing a minimum 300-meter buffer zone between the TPA and residential areas, implementing sanitary landfill methods to replace open dumping systems, forming environmentally-based community forums with advocacy strength, and conducting community-based waste management training focusing on high-risk households. Strengthening participatory approaches through integration into village and sub-district spatial planning is essential for managing environmental impacts collaboratively and sustainably.

Abstract

Tourism is a sector strategy in encouraging regional economic growth, cultural preservation, and improving community welfare. Binjai City, as one of the buffer areas of Medan Metropolitan, has a number of areas that have the potential to be developed into leading tourist destinations. However, un-til now there has been no directed and integrated development strategy for areas that have this potential.This research aims to identify and analyze the potential for the development of leading tourist areas in Binjai City through the Mixed Methods approach, which is a combination of qualitative and quantitative methods. The focus of the study is directed at three strategic areas, namely Taman Merdeka Binjai, the Binjai Grand Mosque Area, and the Jalan Veteran Culinary Village, which have strong historical, so-cio-cultural, and local economic potential but have not been optimally exploited.Data was collected through a survey of 150 respondents consisting of tourists, MSME actors, local communities, and government officials, as well as in-depth interviews with 12 key informants. The re-sults of the quantitative analysis showed that the attractiveness of the area and community support re-ceived the highest score in respondents' perception, while infrastructure and the use of digital technolo-gy are aspects that still require special attention. Qualitative analysis supports these findings, where vari-ous technical and institutional constraints are still found that hinder sustainable development.The results of data integration show that the potential for the development of leading tourist areas in Binjai City is quite high in terms of location, cultural value, and support from the local community. However, to realize a competitive region, strategic interventions are needed in the form of improving the quality of infrastructure, digitizing promotions, and collaboration between sectors. Policy recommenda-tions are filled with institutional capacity strengthening, community empowerment, and the establish-ment of tourism development programs based on local and sustainable potential.

Abstract

Sustainable management of coastal spaces is a major challenge in urban-coastal planning, especially in vulnerable areas such as Medan Belawan. This study aims to identify and analyze the influence of six independent variables on the sustainability of coastal space management. The variables studied included Microecological Inequality, Inclusivity of Coastal Asset Ownership, Adaptive Preparedness to Climate Risks, Inter-Functional Spatial Connectivity, Local Institutional Accountability, and Communal Social Resilience. The method used is a quantitative approach with a multiple linear regression model on primary data obtained through surveys, field observations, and in-depth interviews with 150 respondents.The results showed that five of the six variables had a significant effect on the sustainability of coastal space management. The most dominant variable was Local Institutional Accountability, followed by Asset Inclusivity, Ecological Inequality, Social Resilience, and Adaptive Readiness. Meanwhile, Connectivity between Spatial Functions does not have a significant impact. The regression model shows an R² value of 0.539 which means that 53.9% of the variation in coastal space management can be explained by these six variables.These findings imply the importance of strengthening participatory governance, equitable distribution of space access, and building community's adaptive capacity as a cornerstone for contextual and sustainable coastal spatial planning. Strategic recommendations are directed at institutional reform, community-based planning, and micro-ecological conservation in urban-coastal areas.

Abstract

This study aims to analyze the influence of domestic wastewater management and space utilization control on pests in river-equivalent areas in Lalat Regency. The main problem raised is the low effectiveness of environmental management in the corresponding area due to the increase in domestic activities and its weakness in spatial planning. The approach used is quantitative with multiple linear regression methods. Primary data were obtained through questionnaires to 200 respondents, and secondary data were obtained through documentation studies and field observations. The results of the analysis showed that simultaneously, the five independent variables (environmental management, space availability, community participation, government supervision, and environmental infrastructure) had a significant effect on the habitat in the corresponding area (p = 0.046). Partially, only waste management (p = 0.016) and community participation (p = 0.042) had a significant effect. A determination coefficient (R²) value of 7.5% indicates that the desires of a region are also influenced by other external factors. Based on these findings, it is recommended that the need to improve the household waste management system through the construction of communal WWTP and improve the quality of household septic tanks, as well as community empowerment through the establishment of environmental forums and sustainable sanitation education to support spatial control and poverty in commensurate areas.

Abstract

The Community-Based Sanitation Program (PAMSIMAS) is a government initiative aimed at improving community access to proper sanitation facilities, particularly in rural areas. This study aims to evaluate the effectiveness of the program in Tanjung Aman Village, Wampu District, Langkat Regency. A qualitative approach was used with a phenomenological method, focusing on the experiences and perceptions of local residents and village officials regarding program implementation. Data were collected through in-depth interviews, field observations, and documentation, involving 15 informants comprising residents, sanitation cadres, and village officials. The findings show that technically, the sanitation facilities function well; however, sustainability in usage faces challenges such as low community participation, weak maintenance systems, and the absence of binding local regulations. Community perception of the program is generally positive, particularly regarding improvements in environmental cleanliness and comfort in using the facilities, yet unequal access remains a significant issue. The study concludes that the success of PAMSIMAS largely depends on collaboration among the community, local cadres, and village policies. Strategic recommendations include the formulation of Village Regulations, regular training for cadres, and the establishment of a community-based sanitation management institution. With this approach, the program is expected to operate sustainably and provide long-term benefits to rural communities.
