Abstract

Gresik urban area is dominated by industrial, housing, trade and services activities. The growth of activities contributes to the land use change from green open spaces into built-up areas. The impact of land use change influence the level of air pollution and CO2 gas emission in Gresik urban area. The previous study briefly shows that this urban area produces 50.37% of the total CO2 gas emissions. The production of CO2 gas emissions should be controlled to reduce the impact of climate change in urban areas such as increasing urban temperature, hydrological cycle anomaly, drought, land degradation and other social and environmental issues. The green open space can recycle the CO2 gas emissions and can increase the absorption capacity of the CO2 gas emissions (bio-capacity). The land cover change for built-up area potentially reduces the absorption of CO2 gas emissions in Gresik urban area. Therefore the identification of the land cover change on CO2 emission absorption becomes an objective of this study. The preliminary study can formulate the strategic steps in the development of Gresik urban area that supports urban greenery and adaptive effort to respond the climate change. The study is conducted in two steps. The first step is to analysis the land cover change based on the Landsat satellite imagery analysis. The second step is to measure the dynamic change of the region's ability(bio-capacity) to absorb CO2 emissions by using ecological footprint analysis. The results show that Gresik urban area has a high development of developed land to the North area, Manyar Sub District. The growth of the developed land is more converting the fishpond land. The green areas in this regiontend to be influenced by farming activities which also convert into fishpond land. Bio-capacity of CO2 gas emission absorption increases from 2003 of 3.548 gha to 5.656 gha but the comparison between bio-capacity of CO2 gas emission absorption and developed land shows the declining tendency in each year. In 2003, the comparison score is 1.59 gha/ha of developed land. In 2014, the score is declining into 1.48 gha/ha or developed land.

Abstract

Pembangunan kawasan kampus Institut Teknologi Kalimantan mengakibatkan perubahan fungsi lahan dan meningkatkan nilai koefisien pengaliran (c). Kondisi ini berbanding lurus dengan peningkatan nilai debit limpasan (hidrologi). Berdasarkan kondisi ini, maka perlu dilakukan evaluasi terkait sistem drainase eksisting pada Fakultas MIPA ITK untuk mengetahui kapasitas saluran dalam mengalirkan debit limpasan (hidrologi) yang terjadi. Dalam penelian ini dilakukan analisis hidrologi untuk menghitung debit puncak pada Fakultas MIPA dengan menggunakan metode rasional dan analisis hidrolika untuk mengetahui kapasitas saluran eksisting dengan menggunakan metode manning. Analisis ini bertujuan untuk mengetahui perbandingan antara debit hidrologi dengan kapasitas saluran Fakultas MIPA. Hasil analisis didapatkan debit limpasan yang terjadi pada Fakultas MIPA memiliki nilai yang bervariasi antara 0,007 m3/detik hingga 0,300 m3/detik. Dalam sistem drainase Fakultas MIPA terdapat 7 saluran tersier, 8 saluran sekunder dan 2 saluran primer yang mengalami kelebihan kapasitas sehingga terjadi luapan. Debit luapan yang terjadi pada kawasan Fakultas MIPA bervariasi mulai dari 0,001 m3/detik hingga 0,163 m3/detik.

Abstract

Kelurahan Selili, Kota Samarinda merupakan suatu kawasan yang memiliki potensi bencana longsor. Berdasarkan pada tahun 2015-2022 bahwa Kelurahan Selili memiliki 16 kejadian longsor dan merupakan lokasi yang memiliki kejadian terbanyak di Kota Samarinda. Dampak kejadian longsor di Kelurahan Selili tersebut mengakibatkan kerugian dan kerusakan serta korban jiwa. Oleh maka dari itu peneliti ingin mengetahui seberapa besar intensitas dampak kejadian longsor di Kelurahan Selili, Kota Samarinda. Metode dalam penelitian ini adalah dengan menggunakan analisis skoring overlay. Adapun Variabel dalam penelitian ini yaitu Jumlah kejadian longsor, jiwa terpapar, kerugian kerusakan rumah, kerugian kerusakan fasilitas umum serta luasan longsor. Setelah dilakukan analisis s maka didapatkan hasil penelitian didapatkan melalui analisis Skoring bahwa intensitas dampak kejadian longsor kelurahan selili terdiri dari intensitas dengan rendah hingga sedang. Intensitas rendah berada pada titik 2-8, titik 10, titik 12, dan titik 14, sedangkan kategori sedang berada pada titik 1, titik 9, titik 11, dan titik 14.
