Abstract

Surabaya City is the second-largest city based on the population in Indonesia that is affected by the development of urban planning in the city. The development of the urban areas affected the increase of socio-economic development and peri-urban demographics but often took over land or green open spaces. It is an unavoidable possibility of air pollution due to the imbalance between oxygen producers and existing oxygen users. It is necessary to calculate the prediction of green open space requirements using the Gerarkis Method, which predicts green open spaces based on oxygen demand by using the number of residents, motor vehicles, livestock, industrial factories, and hotels. With the Gerarkis Method, the prediction of the need for green open space in Surabaya City for 2010–2020 is 22,088.89 hectares to 31,950.84 with the increased majority value in the area, except in 2015 and 2020, due to decreased users. This method proves that the need for oxygen produced from plants is increasing, making Surabaya City needs more green open space to make Surabaya City livable.

Abstract

River as the boundary is listed in the 1915 Netherland-British Agreement with its Annex Map without any clear coordinates. This is an obstacle in tracing boundaries in the real river because where river is dynamic, changes in the river shape and river bank can occur in more than 100 years. Multi-temporal Landsat satellite imagery processed with a combination of bands (color composite) is used to observe the position of the river bank from 1989 to 2019 with visual interpretation and manual digitization. As a result, over 30 years there was a shift in the Sikapal river bank with an average of 11.4 m on the right side (Indonesia) and 15 m on the left side (Malaysia). The average shift of the Tamboe river bank is the right side 25.1 m and on the left side 8.8 m. The shift is relatively small because around the Sikapal and Tamboe rivers banks are overgrown by mangrove forests which can slow down the rate of erosion. River banks in 1989, 1999, 2009 and 2019 were used as a basis for delimitation of the Indonesia-Malaysia boundary using a three-stage approach. As a result, there are differences in the shape of the boundary line although it is small. However, the river area of Indonesia and Malaysia still has a proportional ratio of 1: 1.03 in 1989, 1999, 2009 and 2019. Although the ratio is the same, the area of the river has increased by 0.08-0.11 km2.

Abstract

Selat Sunda memiliki peran oseanografi yang strategis karena menghubungkan Laut Jawa dengan Sumatera melalui Selat Sunda. Metode yang digunakan meliputi pemanfaatan data batimetri GEBCO dan data arus reanalysis CMEMS periode 1993–2020, ekstraksi profil vertikal arus zonal dan meridional hingga kedalaman 60 m, serta analisis korelasi Pearson antara kecepatan arus dan kedalaman dengan tujuan untuk menganalisis kontribusi kedalaman dasar laut terhadap karakteristik arus laut musiman secara spasial dan vertikal di Selat Sunda, serta mengkaji hubungan linier antara kedalaman dan kecepatan arus pada skala multi-musim. Hasil penelitian menunjukkan bahwa variasi kedalaman laut memberikan pengaruh signifikan terhadap dinamika arus musiman, ditunjukkan oleh korelasi negatif yang konsisten antara kedalaman dan kecepatan arus pada seluruh musim. Pada musim JJA, pengaruh Muson Tenggara menghasilkan lapisan campuran yang tebal hingga sekitar ±40 m dengan struktur arus yang relatif homogen dan magnitudo tertinggi (≈0,7–0,8 m/s). Sebaliknya, musim DJF memperlihatkan struktur arus yang lebih kompleks dan bersifat baroklinik, ditandai oleh pembalikan arah antara lapisan permukaan dan lapisan bawah. Secara keseluruhan, interaksi antara morfologi dasar laut, sistem monsun, dan proses hidrodinamika regional memainkan peranan penting dalam membentuk variabilitas arus di Selat Sunda. Temuan ini memiliki implikasi penting bagi pengembangan kajian oseanografi fisis serta dapat menjadi dasar ilmiah dalam mendukung perencanaan keselamatan pelayaran, pengelolaan wilayah pesisir, dan mitigasi risiko kelautan di Selat Sunda.
