Abstract

Pencemaran udara yang disebabkan oleh emisi gas kendaraan bermotor menjadi masalah lingkungan utama di Kota Malang, terutama pada ruas-ruas jalan yang mengalami kemacetan parah. Penelitian ini bertujuan untuk menganalisis pengaruh kemacetan lalu lintas terhadap kualitas udara dengan mengukur konsentrasi polutan udara, yaitu NO2, CO, dan SO2, di beberapa ruas jalan utama seperti Jalan Gatot Subroto, Jalan Panglima Sudirman, Jalan Trunojoyo, dan Jalan Untung Suropati. Metode yang digunakan adalah penelitian deskriptif kuantitatif dengan pengukuran langsung selama 12 jam dari jam 06.00 hingga 18.00 WIB, menggunakan alat pengukur kualitas udara. Hasil penelitian menunjukkan bahwa konsentrasi polutan seperti NO2, CO, dan SO2 masih berada dalam kategori baik menurut Indeks Standar Pencemar Udara (ISPU) 2020, meskipun terjadi fluktuasi yang signifikan pada jam-jam puncak kemacetan. Penelitian ini juga menunjukkan bahwa faktor lingkungan seperti ruang terbuka hijau dan kondisi cuaca mempengaruhi penurunan konsentrasi polutan. Implikasi dari penelitian ini adalah perlunya pengelolaan lalu lintas yang lebih efisien dan peningkatan ruang terbuka hijau untuk mengurangi dampak pencemaran udara akibat kemacetan.

Abstract

Accelerating the duration of construction projects has the potential to increase costs, so an analytical approach is needed to balance time and costs efficiently. This study analyzes the application of the Time–Cost Trade Off (TCTO) method in project scheduling optimization by evaluating the relationship between time acceleration and total cost changes. The study uses data on normal duration and accelerated duration, direct costs, and additional costs due to overtime. The analysis methods include the Critical Path Method (CPM) to identify critical activities and TCTO-based crashing analysis to determine economical acceleration alternatives. The results show that the normal project duration is 151 days with a total cost of IDR 1,634,386,623.07. The application of 2 hours of overtime resulted in a duration of 131 days with a total cost of IDR 1,811,132,883.32, while 3 hours of overtime reduced the duration to 123 days with a total cost of IDR 1,817,213,981.61. These findings indicate that accelerating the project duration has an impact on increasing costs, so the selection of an acceleration scenario needs to consider the trade-off between time reduction and additional costs as the basis for project scheduling decisions.

Abstract

Therefore, from the performance results of the Dinoyo intersection and the Sardo intersection of Malang city which refers to the 2023 Indonesia Road Capacity Guidelines, and the air quality is guided by the Regulation of the Minister of Environment and Forestry No. 14 of 2020, the degree of saturation for 3 days of observation is still more than 0.85 with the service level E due to the service level is still poor, so it is necessary to plan improvements at the Dinoyo intersection of the signalized intersection with geometric widening while in The unsignaled junction of the Sardo junction is planned with road geometry on each arm of the road. The largest delay value is 24.175 sec/smp so that the level of intersection service produced is at least D., while at the Sardo junction the degree of saturation for 3 days of observation is still more than 0.85 with service levels B and C. and the air quality is measured at 06.00 – 07.00 with a delay value of 39.765 sec/smp, then the particulate concentration obtained NO2 is the ISPU value of 21.170 (18 ppm),  SO2 ISPU value: 47.866 (19 ppm), C0 ISPU value: 15.609 (1090 ppm). The results of the air quality analysis show that the CO air quality parameter has a great influence on the environmental profile and the decline in public health due to air pollution due to high gas emissions from high vehicle volumes. https://hardtechgroup.net/menelusuri-dimensi-slot-petualangan-di-kasino-online-indonesia/ https://xoompages.com/zeus-slot-gacor-memahami-rahasia-kemenangan-di-permainan-kasino-online/ https://barcelonajerseys.net/panduan-lengkap-slot-gacor-menyelami-strategi-dan-taktik-untuk-menang-di-kasino-online/ https://wedoassignmenthelp.com/menemukan-slot-gacor-hari-ini-strategi-dan-tips-untuk-memaksimalkan-kemenangan-anda-di-kasino-online/ https://freepostarticles.com/sejarah-terkini-dan-relevansi-martha-di-dunia-kasino-online/ https://onestylishday.com/menelusuri-dimensi-tersembunyi-dalam-permainan-slot-di-kasino-online-indonesia/ https://www.budapestresources.com/mengenal-fenomena-slot-gacor-rahasia-di-balik-kesuksesan-permainan-kasino-online/ https://thelimitsofcontrol-laura.com/panduan-lengkap-zeus-slot-gacor-untuk-pemain-online-casino-di-indonesia/ https://maquinasdecosertop.com/slot-gacor-hari-ini-menyelami-dunia-mesin-slot-yang-menguntungkan/ https://whitecrack.com/sejarah-martha-evolusi-di-dunia-kasino-online/
