Relationship between Waste Cover Area with Physical and Chemical Characteristics of Mangrove Ecosystem in Pulau Dua Nature Reserve, Serang, Banten
Full text linkPulau Dua Nature Reserve has undergone significant changes to its land, affecting its physical and chemical properties. Additionally, the increasing problem of scattered plastic waste raises concerns about its negative impact on the ecosystem. This study aims to analyze the physical and chemical characteristics of Pulau Dua Nature Reserve and examine the relationship between the proportion of plastic waste cover area and environmental parameters. Microclimate, soil, and plastic waste proportion area data, especially plastic, were collected at 34 points using systematic random sampling, while water salinity was measured using accidental sampling because the pools for measuring salinity were not spread throughout the research area. A comparative analysis based on literature review and previous studies with mangrove ecosystems indicates that Pulau Dua’s mangrove vegetation is under threat from various environmental factors. Among these, the proportion of plastic waste cover area has the strongest correlation as moderate positive correlation with bulk density in Pearson Correlation Matrix. Independent Sample T-test comparing plastic waste cover area proportion based on bulk density class confirms that class 4 significantly affects bulk density. In conclusion, several physical and chemical parameters in Pulau Dua Nature Reserve do not align with optimal conditions for mangrove vegetation. The most related factors to plastic waste cover area proportion are bulk density because the indication is that areas covered with plastic waste are areas that are frequently passed by humans, thus increasing the bulk density of the soil. Value of bulk density will significantly different when proportion of plastic waste cover more than 2.5% based on Independent Sample T-test

Striking a Balance Between Nature and Development: Investigating Private Green Spaces using ENVI-met
Full text linkThis research investigated the significant effects of private green spaces on air temperatures in Bekasi City. Previous analyses suggested that green spaces could lower air temperatures. Meanwhile, private green spaces, consisting of front and back yards, are a significant part of the concept. Software simulation (ENVI-met) was used to compare several housing scenarios for the tropical monsoon climate of Bekasi City. The scenarios consisted of housing configurations with the same unit size and number in an area of (49 x 49) m2. The results showed that the average air temperature reduction was mostly insignificant. On December 21, the scenarios with the highest and lowest average air temperatures differed by 0.42 ℃ at noon. In this context, the scenario with the most area of green space did not possess the lowest air temperature, due to the increase in building and pavement areas. Wind, sun position, surface area, and type of exposed area affected the outdoor air temperature. Further research could be conducted on innovations, especially regarding building and pavement materials to mitigate air temperature increases
Optimasi Kapasitas Aircraft Parking dengan Menggunakan Metode Kombinasi No-Fit Polygon
No full textOptimasi kapasitas area parkir diperlukan untuk memaksimalkan pemanfaatan ruang, mencegah blocking pada taxiway yang mengganggu operasional MRO, dan mengurangi resiko terjadinya tabrakan antar wingtip pada saat terjadi kepadatan di area parkir. Namun, penerapan metode No-Fit Polygon (NFP) yang dikembangkan pada penelitian sebelumnya masih menghasilkan pola parkir pesawat yang saling tumpang tindih dan kurang optimal. Oleh karena itu, penelitian ini mengusulkan metode kombinasi No-Fit Polygon untuk mengatasi masalah tersebut. Penelitian ini diawali dengan membuat model grafis pesawat dan membuat NFP antara 2 pesawat menggunakan persamaan geometri berdasarkan data geometri pesawat. NFP yang dihasilkan kemudian dikombinasikan dan kapasitas area parkir dioptimalkan menggunakan Mixed Integer Linear Programming (MILP) dengan pemrograman Python berdasarkan geometri area parkir pesawat yang digunakan. Hasil optimasi menunjukkan pesawat dengan luas yang lebih kecil dapat ditempatkan dengan jumlah lebih banyak dibandingkan dengan pesawat dengan luas yang lebih besar, sehingga kapasitas area parkir meningkat sebanyak 3.75% dari 8 menjadi 11 pesawat tanpa safety margin. Penelitian ini menyimpulkan bahwa metode kombinasi NFP dapat digunakan untuk memaksimalkan pemanfaatan area parkir tanpa terjadi tumpang tindih meskipun tanpa penambahan safety margin
Examining the Correlation between Contractual Elements and Construction Project Performance; A Comprehensive Study of Case Studies in Educational Building Projects
Full text linkBuildings constitute the primary infrastructure supporting the effective execution of learning activities within higher education environments. The quality of these buildings is a paramount concern for all stakeholders involved. However, ensuring high-quality construction remains a challenge in building projects. Improving project performance requires construction contract documentation that comprehensively outlines the rights and responsibilities of the parties involved in the project. This research aims to identify the characteristics and relationships among contractual aspects, contract management, and project performance, focusing on improving the quality of construction projects, particularly within higher education institutions. This research applies an exploratory qualitative approach to achieve that goal. The data used results from structured interviews with stakeholders from five universities as study objects. The data processing stages consist of open coding, axial coding, and selective coding, as well as exploring the relationship between research variables using regression analysis. The study revealed three primary project characteristics in higher education institutions: contractual aspects, contract management, and project performance. Key elements within these groups include contract standards, organizational factors, and contract control. Notably, a significant negative correlation between contracts and project performance indicates that issues within contract-related aspects and management adversely impact project outcomes. The findings underscore the importance of effectively managing the involvement of multiple stakeholders in construction projects. Collaborative management between stakeholders and project management is essential for ensuring project success, particularly in quality monitoring, adherence to timelines, and profitability
