 Remote sensing technology such as small format aerial photography (SFAP) from unmanned aerial vehicle (UAV) or drone can be a solution in accelerating the land parcel mapping in Indonesia. This study aims to determine the level of geometric and planimetric accuracy of SFAP data output in land parcel mapping and describe the step of data processing. The results showed that in land parcel mapping, the main SFAP output data is orthophoto. Therefore, the processing should not need to do the dense cloud process, the orthophoto build process can use DEM from sparse cloud for time efficiency and reduce the relief displacement effect. The orthophoto geometry accuracy is CE90 of 0.44, so it is very well used for mapping 1: 2500 scale, while DSM has a LE90 value of 2.80. Planimetry accuracy of the land parcel distance has met the tolerance standard, while planimetry accuracy of the land parcel area there is 1 parcel that does not meet the tolerance standard. However, in general, SFAP can be used as a basis for land parcel mapping in slightly hilly areas such as Bompon watershed.Keywords:     Small format aerial photo, land parcel, geometric accuracy, planimetric accuracy Teknologi penginderaan jauh seperti foto udara format kecil (FUFK) dari pesawat nir awak bisa menjadi solusi dalam percepatan pemetaan bidang tanah di Indonesia. Penelitian ini bertujuan untuk mengetahui tingkat ketelitian geometrik dan planimetrik data keluaran FUFK dalam pemetaan bidang tanah serta mendeskripsikan tahapan-tahapan pengolahan datanya. Hasil penelitian menunujukkan bahwa dalam pemetaan bidang tanah, data keluaran FUFK yang utama adalah ortofoto. Oleh karena itu sebaiknya proses pengolahan tidak perlu melakukan proses dense cloud, proses build orthophoto bisa menggunakan DEM dari sparse cloud untuk efisiensi waktu serta mengurangi efek relief displacement. Ketelitian geometri ortofoto yaitu CE90 sebesar 0,44, sehingga sangat baik digunakan untuk pemetaan skala 1:2500, sedangkan DSM memiliki nilai LE90 sebesar 2,80. Ketelitian planimetrik terhadap jarak bidang tanah telah memenuhi standar toleransi, sedangkan ketelitian planimetrik terhadap luas bidang tanah terdapat 1 bidang yang tidak memenuhi standar toleransi. Walaupun begitu, secara umum FUFK bisa digunakan sebagai dasar pemetaan bidang tanah di wilayah yang sedikit berbukit seperti Sub DAS Bompon.Kata Kunci:  Foto udara format kecil, bidang tanah, ketelitian geometrik, ketelitian planimetrik.

This research was carried out in Wuryantoro Watershed, Wonogiri. The goal of this study is to examine the remote sensing technology capability to obtain the physical characteristics data of watershed in the prediction of runoff coefficient using cook method. The physical characteristics is topography (relief), landcover, water storage, and infiltration. The physical characteristis is interpreted on infrared aerial photography on scale 1 : 10.000 based on element of interpretation i.e. tone, texture, size, shape, pattern, site, and association. The result of the prediction is tested by comparing them with the data of field measurement result. The accuraccy of the result of aerial photo interpretation of physical characteristics of watershed can be obtained as follows 1) the accuracy of the interpretation of landuse 88,5%; 2) the accuracy of slope interpretation 87.67%. The accuracy of prediction of the runoff coeficient 86.9%.

A comprehensive monitoring procedure for TPP ash dumps in the climatic conditions of Siberia is proposed, which involves implementation of two stages. At the global stage, remote sensing technology is used directly from spacecraft in Earth’s orbit, while at the regional stage, an unmanned aerial vehicle and numerical modeling are used. An example of the operations is given, which clearly shows how exactly this procedure will increase efficiency of the TPP ash dump monitoring in the climatic conditions of Siberia and help promptly take measures required to prevent collapse of the ash dump external soil structure, which may result in ash and slag waste outflow and contamination of the adjacent territory.

Abstrak Teknologi penginderaan jauh mengalami perkembangan yang sangat pesat. Salah satunya adalah teknologi akuisisi data dengan menggunakan UAV (Unmanned Aerial Vehicle).  Teknologi UAV dapat dipergunakan dalam berbagai bidang, salah satunya adalah bidang kebencanaan. Tujuan penelitian ini adalah untuk melakukan pemetaan secara cepat kawasan terdampak bencana banjir dan longsor di Kabupaten Bangli, Bali dengan menggunakan teknologi UAV. Metode yang digunakan adalah pemotretan udara dengan UAV, survei lapangan dan analisis laboratorium. Pemotretan udara dilakukan satu hari pasca kejadian longsor dengan ketinggian jelajah pesawat antara 100-120 meter di atas permukaan tanah. Resolusi spasial yang dihasilkan antara 4,5 - 6,5 cm. Wilayah yang berhasil dipetakan adalah wilayah yang terdampak banjir dan longsor di Desa Songan A serta Songan B, wilayah terdampak banjir bandang Yeh Mampeh di Desa Batur Selatan, serta wilayah terdampak longsor di Desa Sukawana dan Desa Awan. Berdasarkan hasil pemotretan udara, dapat diketahui luasan daerah terdampak longsor. Lebih lanjut, strategi rehabilitasi dan rekonstruksi dapat dilakukan dengan menggunakan hasil pemotretan udara.  Abstrak Remote sensing technology is experiencing rapid developments. One of which is in the field of data acquisition that has currently adopted the use of Unmanned Aerial Vehicle (UAV). UAV technology is, for instance, employed in various studies related to disasters. This research aimed to perform a rapid mapping of flood- and landslide-affected areas in Bangli Regency, Bali using UAV technology. The applied methods included UAV-assisted aerial photography, field survey, and laboratory analysis. The aerial photography was conducted one day after the landslide event and at a recording altitude of 100-120 m above the ground. The spatial resolution produced in the photography was 4.5-6.5 cm. The mapped areas were the ones affected by floods and landslides in Songa A and Songa B Villages, flash floods in Yeh Mampeh, Batur Selatan Village, and landslides in Sukawana and Awan Villages. The aerial photography also provided the extent of the landslide-affected areas. Therefore, the post-disaster rehabilitation and reconstruction strategies can be implemented using the results of the aerial photography.

Submarine pipelines must be designed to resist wave and current induced hydrodynamic forces especially in and near the surf zone. They are buried as protection against forces in the surf zone, however this procedure is not always feasible particularly on a movable sea bed. For this reason the characteristics of the sediment transport on the construction site of beaches should be investigated. In this investigation, the application of the remote sensing method is introduced in order to determine and observe the coastal morphology, so that submarine pipelines may be protected against undesirable seabed movement.
