Flood Mitigation Strategies for Settlement Area in Kediri District
Get PDFMengacu pada IRB (Indeks Risiko Bencana) yang dirilis oleh BNPB pada tahun 2013, menunjukkan bahwa Kabupaten Kediri merupakan salah satu wilayah administratif di Jawa Timur yang memiliki indeks bencana yang tinggi, salah satunya adalah banjir. Berdasarkan data BPS Kabupaten Kediri dari tahun 2012 hingga 2019 terjadi peningkatan jumlah penduduk sebesar 0,5-1%. Pada tahun 2007-2019 jumlah penduduk meningkat sebesar 8% disertai dengan peningkatan jumlah kawasan pemukiman sebesar 25%. UU Nomor 24 Tahun 2007 Pasal 47 menyatakan bahwa untuk mengurangi risiko bencana bagi masyarakat yang tinggal di daerah rawan bencana, yang harus dilakukan adalah melakukan tindakan mitigasi. Hasil penelitian menunjukkan bahwa wilayah dengan indeks kerawanan banjir tinggi berada di Kecamatan Badas, Kras, dan Ringinrejo. Hasil evaluasi lahan pemukiman yang ada di ketiga wilayah tersebut juga berdiri di atas lahan yang tidak sesuai untuk pemukiman dan berdaya dukung rendah. Sehingga didapatkan lima kriteria beserta alternatif strategi mitigasi yang sesuai untuk diterapkan di Kabupaten Kediri khususnya di wilayah pemukiman yang rentan banjir.Referring to the IRB (Disaster Risk Index) released by BNPB in 2013, it shows that Kediri District is one of the administrative areas in East Java that has a high disaster index, one of which is flooding. Based on BPS data from Kediri Regency from 2012 to 2019 there was an increasing the population of 0.5-1%. In 2007-2019 the population increased by 8% accompanied by an increase in the number of residential areas by 25%. UU Number 24 of 2007 Article 47 states that to reduce disaster risk for people living in disaster-vulnerability areas, what must be done is to take mitigation actions. The results showed that areas with high flood vulnerability index were in the Badas, Kras, dan Ringinrejo. The evaluation results of the existing residential land in the three areas also stands on land that is not suitable for settlement and has low carrying capacity. So that five criterias are obtained along with alternative mitigation strategies that are suitable to be applied in Kediri District, especially in flood-vulnerability residential areas

Get PDFPembangunan bandar udara baru dengan konsep aerotropolis di Kulon Progo telah menstimulus pembangunan dan mengubah wajah kawasan dari rural-oriented menjadi urban-oriented. Dampak negatif pertumbuhan yang cepat seperti munculnya fenomena urban sprawl perlu diantisipasi melalui perencanaan tata ruang yang berkelanjutan. Penelitian ini bertujuan untuk mengevaluasi daya dukung berbasis kemampuan lahan pada penggunaan lahan eksisting dan rencana tata ruang. Metode yang digunakan untuk evaluasi daya dukung adalah matching criteria. Hasil analisis menunjukkan bahwa 56,13% wilayah Kulon Progo didominasi oleh kelas kemampuan agak rendah hingga rendah (kelas V-VIII) dengan faktor pembatas utama berupa lereng. Evaluasi keselarasan dengan penutupan/penggunaan lahan 2020 menunjukkan bahwa sebagian besar penggunaan lahan berada pada status selaras (S) dan selaras bersyarat (SB). Penggunaan lahan yang tidak selaras dengan daya dukungnya seluas 8.286,44 ha yang terdistribusi di bagian selatan. Sementara, evaluasi terhadap rencana tata ruang wilayah (RTRW) Kabupaten Kulon Progo menunjukkan bahwa 57% rencana selaras dengan kemampuan lahan. Namun demikian, daya dukung lahan di Kulon Progo dalam kondisi yang cukup baik. Intervensi perencanaan perlu dilakukan untuk wilayah-wilayah yang memiliki status selaras bersyarat dan tidak selaras.The new aerotropolis era due to airport construction in Kulon Progo has stimulated regional development and changed the image of the area from rural to urban-oriented. The negative impact of rapid growth, such as the urban sprawl, can be mitigated through sustainable spatial planning. Therefore, this study aims to evaluate the carrying capacity based on the land capability of both existing and official land use planning. The matching criteria method was used to conduct the capability evaluation. According to the analysis results, 56.13% of the Kulon Progo area was dominated by moderate to low land capability classes (V-VIII) with the main inhibiting factor as slopes. Furthermore, the evaluation of conformity with land use/land cover (LULC) in 2020 showed most land uses were in not conform (NC) and conditionally conform (CC) status. The area of land use that did not conform with its carrying capacity was 8,286.44 ha which was distributed in the southern part. Meanwhile, an evaluation of the official land use planning of the area showed 57% of the plan was conform (C) with land capability. Therefore, the carrying capacity of the land in Kulon Progo is in reasonably good condition. However, planning interventions should be carried out for areas with not conform status
The role and perception of accountants on environmental management accounting in an emerging market: Study on South Africa’s companies.
Get PDFThis research explores the role and views of accountants in environmental management accounting (EMA) and environmental performance. The study relied on a survey of 86 chief finance officers, accountants and finance managers from the top 40 listed South African companies. The chief finance officers, accountants and finance managers confess that they lack understanding on in what way environmental issues can be incorporated into EMA. In addition, the professionals disclose that EMA has not had an ample consideration by their companies. This suggests that a limited involvement by the accountants in EMA in South Africa exists. Hence, the sampled chief finance officers, accountants and finance managers indicated that they are not sure of their potential responsibility. This shows that South African accountants are noticeably absent from participating in EMA. This has been ascribed to EMA being a new branch of accounting, their little aptitude in environmental issues and also the voluntary nature bestowed on EMA practices. Therefore, this paper will increase literature on the views of accountants on EMA from a developing country’s perspective
