Abstract

The Dinger Mausoleum is a tomb with a Dutch architectural style that was used to store the body of a Dutch national named Jan Dinger and has been designated as a cultural heritage building by the Batu City Government. This tomb with its status as a cultural heritage must be tried to preserve and preserve its original form in accordance with Law No. 11 of 2010 concerning Cultural Heritage. In this study, conservation efforts were carried out by documenting the tomb in the form of a 3D reconstruction model. Documentation activities are carried out by acquiring data and creating 3D models from Dinger Mausoleums both from the outside (exterior) and from inside (interior) considering that the tomb is in the form of a building which means it has space inside, using close-range photogrammetric methods. The 3D model that has been formed is then analyzed for the level of accuracy of the data acquisition and tomb modeling process. An analysis of the level of suitability in the 4th order class (LoD4) is also carried out because 3D modeling includes the interior of the tomb building. The results of the data acquisition took the form of exterior photos and photos of the interior of the Dinger Mausoleum, and the results of the analysis of the RMSE values were less than 0.2 m, thus fulfilling the Level of Detail 4 criteria (LOD 4).

Abstract

Fishing Potential (PPI) is needed to increase fisheries productivity. Traditionally, fishermen use their senses and hereditary habits to determine PPI. Traditionally, fishermen use the five senses and hereditary habits to determine PPI. This method, in addition to being less efficient, can also lead to over-exploitation if fishing is carried out in the same place continuously. The existence of remote sensing technology can be used to determine PPI faster while considering aspects of approval and spatial distribution. One method of determining PPI is based on remote sensing data, mapping the thermal front area first before determining the PPI through manual interpretation based on pixel located between warm and cold water. Manual interpretation has limitations, it depends on humans and takes a long time. To overcome these limitations, in this study, the Single Image Edge Detection (SIED) method developed by Cayulla and Cornillon was applied in the form of a toolbox thus it could be used automatically. Sea Surface Temperature (SPL) data obtained from MODIS Level 2 (6 April 2018) was subsequently processed using this toolbox and successfully developed 22 PPI points in the southern part of Java Island. Meanwhile, PPI detection using the Temperature Gradient Analysis (TGA) method which is done manually produces 28 points. There are 20 locations of the same point using these two methods. Using the SIED method based on the toolbox can improve data, reduce human error with accuracy 64%.

Abstract

Kabupaten Rembang merupakan salah satu kawasan yang berada di pesisir pantai utara jawa dengan luas sebesar 101.408 ha yang secara geografis terletak pada 6o30’- 7o 6’LS dan 111o – 111o30’ BT dengan garis pantai sepanjang 63 km. Panjangnya garis pantai di Kabupaten Rembang memungkinkan banyaknya aktivitas di wilayah pesisir yang akan berdampak pada banyaknya penggunaan lahan yang tidak sesuai dengan ketentuan semestinya yang banyak mengakibatkan abrasi. Fenomena abrasi yang terjadi pada 30 agustus 2019 di Kecamatan Kragan Kabupaten Rembang yang mengikis pantai sejauh 15 m dengan panjang 1,5 km. Mengingat besarnya ancaman bencana abrasi yang melanda Kabupaten Rembang maka perlu adanya evaluasi penggunaan lahan pada wilayah pesisir terutama di kawasan sempadan pantai. Pada penelitian ini akan dilakukan analisis mengenai kesesuaian kawasan terbangun (Land Use) di area sempadan pantai dengan peta rencana tata ruang wilayah (Land Development). Selanjutnya akan ditampilkan dalam bentuk ArcGIS Online yang akan memudahkan dalam mengakses peta. Hasil dari penelitian yang dilakukan diperoleh empat kelas pada peta rencana tata ruang wilayah yaitu berupa peruntukan pemukiman, industri, sempadan pantai, dan hutan. Selanjutnya luas tertinggi kesesuaian rencana tata ruang wilayah (RTRW) dan kondisi eksisiting adalah untuk kelas industri sebesar 163,497 Ha, pemukiman sebesar 45,798 Ha, sedangkan untuk peruntukan sempadan pantai dan hutan tidak ada luasan yang sesuai dengan rencana tata ruang wilayahnya.

Abstract

Kabupaten Bandung Barat adalah salah satu kabupaten di Provinsi Jawa Barat dengan potensi gerakan tanah yang tinggi, sehingga sangat rentan terhadap kejadian tanah longsor. Hal ini dipicu oleh kondisi topografi yang beragam dan memungkinkan kejadian ini akan terus terjadi di masa depan. Salah satu metode yang sering digunakan dalam pemetaan kerentanan tanah longsor adalah frequency ratio. Metode ini bertujuan untuk mengidentifikasi wilayah rentan tanah longsor berdasarkan data kejadian longsor di masa lalu yang pada gilirannya dapat dijadikan parameter untuk mitigasi bencana longsor. Metode ini diaplikasikan menggunakan aplikasi GIS dengan data-data sekunder seperti DEM, peta tutupan lahan, data curah hujan, peta geologi, dan peta klasifikasi tanah. Data tersebut merepresentasikan faktor-faktor yang memengaruhi tanah longsor yaitu kemiringan lereng, elevasi, arah kemiringan lereng, tutupan lahan, curah hujan, jenis tanah, jarak sesar, dan batuan geologi. Faktor-faktor tersebut ditumpangtindihkan menjadi peta raster (20 m) dan menghasilkan nilai frequency ratio. Nilai tersebut diklasifikasikan menjadi 5 zona kerentanan longsor yaitu tidak rentan, sedikit rentan, cukup rentan, rentan, dan sangat rentan. Hasil penelitian ini menunjukkan terdapat 7 faktor pengkondisi tanah longsor yang memengaruhi kerentanan tanah longsor. Hasil uji akurasi ini menghasilkan peta kerentanan tanah longsor dengan nilai akurasi sebesar 79,7% sehingga dapat diterapkan dalam upaya mitigasi tanah longsor. West Bandung regency is one of the districts in West Java Province with high potential for land movement, making it very vulnerable to landslide events. This is triggered by diverse topographic conditions and allows these events to continue to occur in the future. One of the methods often used in mapping landslide vulnerabilities is frequency ratio. This method aims to identify landslide-prone areas based on data on past landslide events that in turn can be used as parameters for landslide disaster mitigation. This method is applied using GIS application with secondary data such as DEM, land cover map, rainfall data, geological map, and land classification map. The data represents factors that affect landslides, namely slope, elevation, slope direction, land cover, rainfall, soil type, fault distance, and geological rocks. These factors are overlayed into raster maps (20 m) and produce frequency ratio values. These values are classified into 5 landslide vulnerability zones that are not vulnerable, slightly vulnerable, vulnerable enough, vulnerable, and highly vulnerable. The results of this study showed there are 7 factors of landslide conditioning that affect the vulnerability of landslides. This accuracy test resulted in a landslide vulnerability map with an accuracy value of 79.7% so that it could be applied in landslide mitigation efforts.

Abstract

Tanggal 22 Juni 2018 terjadi bencana banjir bandang yang disebabkan oleh tanah longsor di kawasan lereng Gunung Raung di Kecamatan Songgon. Bencana ini menyebabkan ratusan orang mengungsi dan merusak 328 unit rumah. Adanya bencana tersebut, diperlukan analisis terhadap penyebab terjadinya tanah longsor serta melakukan pencegahan dan mitigasi dengan pemetaan potensi tanah longsor. Penelitian ini menggunakan metode analisis Sistem Informasi Geografis (SIG) dan pembobotan Analytical Hierarchy Process (AHP) dengan narasumber pegawai Badan Penanggulangan Bencana Daerah Kabupaten Banyuwangi dan Dosen Teknik Geofisika ITS. Parameter penyebab tanah longsor yang digunakan mengacu pada Permen PU No. 22/PRT/M/2007, parameter tersebut antara lain kemiringan lereng, kondisi tanah, batuan penyusun lereng, kondisi hidrologi, curah hujan, kerentanan gerakan tanah dan tutupan lahan. Hasil dari penelitian ini didapatkan bahwa dengan metode AHP, kerentanan gerakan tanah mempunyai pengaruh lebih besar terhadap tanah longsor dengan bobot sebesar 34%, diikuti dengan parameter lain yaitu kemiringan lereng 17%, jenis tanah 14%, curah hujan 14%, jenis batuan 12%, kerapatan sungai 5% dan tutupan lahan 4%. Selanjutnya, didapatkan tiga kelas potensi tanah longsor yaitu potensi rendah sebesar 9.527,09 Ha, potensi sedang sebesar 8.410,19 Ha dan potensi tinggi sebesar 3.283,23 Ha dengan daerah yang berpotensi tinggi terhadap potensi tanah longsor yaitu Desa Bayu dan Desa Sumberarum di Kecamatan Songgon.On June 22 2018, there was a flash flood disaster caused by landslides on the slopes of Mount Raung in Songgon Sub-District. This disaster caused hundreds of people to flee and damaged 328 housing units. The existence of this disaster requires an analysis of the causes of landslides as well as prevention and mitigation by mapping the potential for landslides. This research uses Geographical Information System (GIS) analysis method and weighting of Analytical Hierarchy Process (AHP) with the resource persons of the Banyuwangi Regional Disaster Management Agency and Geophysical Engineering lecturers-ITS. The parameters that cause landslides used refer to Permen PU No. 22 / PRT / M / 2007, these parameters include slope, soil conditions, rock making up slopes, hydrological conditions, rainfall, soil movement vulnerability and land cover. The results of this study found that with the AHP method, soil movement susceptibility has a greater effect on landslides with a weight of 34%, followed by other parameters, namely 17% slope, 14% soil type, 14% rainfall, 12% rock type. , 5% river density and 4% land cover. Furthermore, three classes of landslide potential were obtained, namely low potential of 9,527.09 hectares, medium potential of 8,410.19 hectares and high potential of 3,283.23 hectares with areas that have high potential for landslides, namely Bayu Village and Sumberarum Village in Songgon Sub-District.
