Development of compensation valuation method for marine tourism businesses due to oil spill incident at the sea
Get PDFOne of the functions of the coastal ecosystem is to produce environmental services that can be used for marine tourism. Oil pollution incidents at the sea have caused a decline in the quality of marine tourism objects, thus reducing the number of visitors arriving and then it has implications for decreasing the income of the people who do business at tourist area. The community\u27s claim for immediate compensation payments requires a faster calculation method. The purpose of this research is to develop a method of assessing the economic compensation for marine tourism businesses that are affected by incidents of oil pollution at the sea. The type of this research is descriptive research. The data consists of primary data and secondary data. The steps required in calculating compensation are (1) identifying tourism businesses, (2) building a theoretical concept of compensation, (3) determining the legal basis for calculating compensation, and (4) Designing a compensation formula. The application of the five compensation calculation formulas requires 18 variables. By taking the case of an oil spill incident in the North Sea of Karawang which has an impact on Tanjung Pakis beach tourism, an estimate of the value of compensation (Rp/day) is obtained for the buoy rental service business is Rp 111,323.08, for bathroom services business is Rp 69,504.62, for food/beverage trading business on a small scale is Rp 71,510.77 and for food/beverage trading business on a large scale is Rp 188,569.23. For the next stage, the implementation of compensation needs to be verified against the impacted community and the payment mechanism so that it is right on target

Get PDFLongsor merupakan salah satu jenis pergerakan lereng, dimana pergerakan lereng tersebut termasuk rayapan. Meskipun rayapan tidak berdampak pada resiko korban jiwa, namun pergerakan lereng ini berlangsung secara konstan dan tak terlihat yang berdampak pada kerugian ekonomi. Pada penelitain ini dilakukan suatu pemantauan seri waktu (time-series monitoring) dari tahun 2018 hingga 2020 untuk melihat pergerakan lereng pada daerah penelitian dengan menggunakan metode seri waktu Multi-Temporal Interferometry Synthetic Aperture Radar (MTInSAR) dari data Sentinel 1A/B, yang mencakup Perumahan Trangkil Sejahtera (PTS), Universitas Katolik Soegijapranata (UNIKA), dan Universitas 17 Agustus 1945 (UNTAG) di Kota Semarang, Indonesia. Hasil pengolahan data menunjukkan bahwa terdapat rayapan pada target lokasi, yaitu Perumahan Trangkil Sejahtera dan Selorejo (sebelah Baratdaya UNIKA). Berdasarkan data BPBD 2021, terjadi longsor di Perumahan Trangkil Baru (sebelah Utara PTS) dan talud longsor Sungai Garang sebelah barat Selorejo. Hal ini menunjukkan adanya keterkaitan antara rayapan tahun 2018-2020 dengan kejadian longsor pada tahun 2021. Meskipun penggunaan data satelit memiliki beberapa kekurangan, hasilnya dapat menjadi bahan pertimbangan dalam membangun sistem peringatan dini dan mengurangi kerugian akibat longsor.Landslide is one type of slope movement, where the slope movement includes creep. Although creep movement does not have an impact on the risk of loss of life, this creep movement takes place constantly and invisible which has an impact on economic losses. In this study, a time-series monitoring was carried out from 2018 to 2020 to see the movement of the slopes in the study area using the Multi-Temporal Interferometry Synthetic Aperture Radar (MTInSAR). A time series method from Sentinel 1A/B data, which includes Trangkil Sejahtera Housing (PTS), Soegijapranata Catholic University (UNIKA), and 17 August 1945 University (UNTAG) in Semarang City, Indonesia. The results of data processing indicate that there are slope movement in the target location, namely Trangkil Sejahtera and Selorejo Housing (southwest of UNIKA). Based on BPBD 2021 data, landslides occurred in the Trangkil Baru Housing Center (to the north of PTS) and the Garang River landslide channel west of Selorejo. This shows that there is a link between crawling in 2018-2020 and landslides in 2021. Although the use of satellite data has some drawbacks, the results can be taken into consideration in building an early warning system and reducing losses due to landslides
