Abstract

Tujuan penelitian ini untuk memperoleh hasil analisis dampak lingkungan dalam audit tata ruang di sebagian Kecamatan Kasihan Kabupaten Bantul. Kecepatan pertumbuhan alih fungsi lahan dan perkembangan sebaran bangunan fisik seperti permukiman, industri, jasa dan niaga yang tidak terkendali dan tidak sesuai dengan peruntukan pemanfaatan ruang, menjadi suatu permasalahan yang dihadapi di sebagian wilayah penelitian. Kasus yang sering dijumpai terutama pada kawasan bantaran sungai, yang seharusnya dilindungi, dimanfaatkan sebagai permukiman, bangunan wisata, industri, perkantoran dan niaga. Demikian pula pada kawasan konservasi atau ruang terbuka hijau sebagai sumber air dan penyimpan sumber air permukaan dapat berubah menjadi kawasan hunian.Desakan-desakan terhadap alam, juga dapat menyebabkan maraknya bencana alam. Sehingga audit tata ruang diperlukan untuk mengetahui kesesuaian pemanfaatan ruang. Metode yang digunakan dalam penelitian ini dengan menggunakan analisis spasial dan analisis dampak lingkungan. Analisis spasial digunakan untuk mengetahui ketidaksesuaian pemanfaatan ruang, sedangkan analisis dampak lingkungan digunakan untuk mengetahui dampak lingkungan atas adanya ketidaksesuaian pemanfaatan ruang yang dihasilkan dari analisis spasial tersebut. Hasil yang diperoleh yaitu terdapat ketidaksesuaian pemanfaatan ruang dengan potensi dampak yang ditimbulkan yakni berupa: peningkatan jumlah timbulan air limbah, peningkatan timbulan sampah, perubahan debit banjir.

Abstract

A tsunami is a disaster that can be hardly estimated. It is a significant concern UN since more than 60% of the world's population lives in coastal areas prone to tsunamis, including Indonesia. The county community with complex and dynamic plate requires mastering of mitigation strategies as a tsunami preventive effort. Understanding the vulnerable elements in risky areas is critical. However, the magnitude of potential disasters cannot be minimized. This study analyzes the tsunami vulnerability in Bantul, Special Region of Yogyakarta (DIY). The analysis was based on a description of assessment parameters such as land use, the physical condition of the area, social conditions, and availability of infrastructure. The results show that social vulnerability had the most significant impact.

Abstract

The establishment of Kulon Progo as a strategic zone must consider the threat of coastal disasters besides aspiring economic growth and development. By employing Unmanned Aerial Vehicles for data acquisition, this research modeled flood inundation and developed theoretical contributions on tsunami hazard, vulnerability, capacity, and risk, as well as a procedural planning system for reconfiguring land use that emphasized the mitigation aspects. This study found that the tsunami hazard index in Glagah Village was in a low category, dominated by vacant land and sandy land, accounting for up to 25.38% of the total area. Besides, vulnerability and risk in Glagah Village were mostly in a moderate index, while its capacity was categorized as high since the village already had an evacuation route, a notable tsunami early warning system, and was equipped with safety gear. By combining the index values for hazard, vulnerability, and capacity, the tsunami disaster risk in Glagah Village was categorized as moderate. Spatial planning in Glagah Village recommended that the main facilities related to community activities, such as transportation and housing, be located in areas not exposed to the tsunami. This plan allows everyone to evacuate themselves while being reinforced by a security warning system that stays on alert. Furthermore, detailed spatial maps are expected to be useful as instruments for tsunami disaster mitigation at the pre-disaster stage by recommending better land use configurations.

Abstract

Kawasan Titik Nol adalah kawasan yang sangat penting dan strategis bagi KotaYogyakarta. Kawasan tersebut menjadi sentra perekonomian, destinasi wisata, cagar budaya, serta kawasan pendidikan. Tingginya intensitas kegiatan termasuk besarnya kunjungan wisatawan juga membawa dampak negatif bagi lingkungan Kawasan Titik Nol, dan salah satunya adalah pencemaran udara. Penelitian dilaksanakan untuk mengetahui tingkat pencemaran udara, khususnya konsentrasi SO2 dan memprediksi sebaran konsentrasi SO2 di daerah ini mengunakan software AERMOD. AERMOD merupakan model dispersi spasial kualitas udara. Sampel udara diambil menggunakan midged impinger. Pengaruh kecepatan angin, kelembaban, suhu terhadap konsentrasi SO2 dianalisis dan kemudian dimodelkan. Hasil penelitian kualitas udara melebihi ambang batas baku mutu yang ditentukan oleh Pemerintah. Hasil SO2 pada hari pertama di titik-titik sampel adalah 879,9 µg/m3 (titik A), 903,9 µg/m3 (titik B dan C) dan pada pengambilan sampel hari kedua sebesar 849,6 µg/m3 (titik A), 755,9 µg/m3 (titik B), 778,8 µg/m3 (titik C), 774,5 µg/m3 (titik D). Prediksi Sebaran SO2 di Yogyakarta menggunakan software AERMOD dan hasil dari windrose sejauh 100 m sampai dengan 600 m ke arah timur dari sumber polutan.
