Building inspection is very much required for all buildings especially those historical ones to maintain the structure condition and the safety of the people around. Visual inspection is commonly conducted using manual descriptive information carried out by the inspector personally. The problem with this technique of assessment is that the time needed to write all the defect description on site and to access difficult area can be hazardous. The aim of performing historical building inspection on Tan Swee Hoe’s historical mansion is to evaluate the overall condition of the building with Unmanned Aerial Vehicle (UAV) image assisted inspection and Condition Survey Protocol 1 (CSP1) method. From this drone assisted inspection, it shows that the time spent on site is less than half an hour and the data collected being evaluated with CSP1 method defined that the building is dilapidated. The overall building condition is in red class and require serious attention to avoid any injuries to the visitors. To prevent a possible failure of a building in the coming years, a suitable condition inspection has been carried out to identify the current existing defect so that it would be fixed before further damage to the building and visitors around it.

AbstractFeature point extraction technology has become a research hotspot in the photogrammetry and computer vision. The commonly used point feature extraction operators are SIFT operator, Forstner operator, Harris operator and Moravec operator, etc. With the high spatial resolution characteristics, UAV image is different from the traditional aviation image. Based on these characteristics of the unmanned aerial vehicle (UAV), this paper uses several operators referred above to extract feature points from the building images, grassland images, shrubbery images, and vegetable greenhouses images. Through the practical case analysis, the performance, advantages, disadvantages and adaptability of each algorithm are compared and analyzed by considering their speed and accuracy. Finally, the suggestions of how to adapt different algorithms in diverse environment are proposed.

ABSTRAKAngka kriminalitas yang meningkat menjadi salah satu permasalahan pembangunan di kota Balikpapan. Tindakan kriminalitas seperti pencurian, penculikan anak, tindakan asusila terhadap perempuan dan sebagainya sangat meresahkan warga. Tidak terkecuali untuk warga perumahan Griya Wiyata Asri (GWA) III, RT 19, Kelurahan Karang Joang, Balikpapan. Sejauh ini, pelaksanaan Siskamling terbukti efektif dalam meminimalisir terjadinya tindak kejahatan di perumahan GWA III, terutama pada malam hari. Namun, permasalahan terjadi pada siang hari karena mayoritas warga perumahan masuk dalam kategori produktif, bekerja sehingga berada di luar perumahan, bahkan ada yang di luar kota. Suasana perumahan sangat sepi, sehingga meninggalkan celah tindakan kriminalitas bisa terjadi pada siang hari. Oleh karena itu, dibutuhkan upaya penanggulan atau pencegahan tindak kriminalitas. Untuk membantu upaya pencegahan tindak kriminalitas, dirakitlah sebuah Unmanned Aerial Vehicle (UAV). UAV ini digunakan untuk memantau kondisi di perumahan GWA III. Metode evaluasi dari pengabdian masyarakat tahap awal ini adalah sebatas melalui  observasi hasil pemantauan udara. Dari hasil foto, kejernihan foto dan kondisi perumahan yang dapat diobservasi secara jelas per bingkai foto udara, maka UAV ini berpotensi untuk digunakan sebagai penunjang siskamling dengan permasalahan kurangnya sumber daya manusia pada siang hari di perumahan GWA III ini.     Kata kunci: UAV; siskamling; keamanan. ABSTRACTBalikpapan, a city of oil. Despite this predicate, it suffer from high criminal level. This incude robbery, child kidnapping, female abuse that have been a great concern in many residential in Balikpapan. One of this residence is Griya Wiyata Asri III Residence. In this residence, a neigbourhood security system has been made. In this system, the resident of this residence have a shift to do a night watching. This system have been effective in the night, but in the daylight, because most of the people are in productive age, most of them working outside of this residential, make this residential empty, thus, making an opportunity for criminal to occur. To answer this probem, an unmanned aerial vehicle was built to monitor the condition of the neighbourhood. The evaluation of this preliminary stage of this community service was done merely from the results of the aerial view. This aerial view, it is so clear and can capture well the activity done in the neighbourhood in a one frame. So, this UAV have a potential to be used as aid to the neighbourhood security system which have a problem on lacking some human resources in the daylight. Keywords: UAV; security; neighbourhood.

The new progressive smart technologies announced in the fourth industrial revolution in aviation—Aviation 4.0—represent new possibilities and big challenges in aircraft maintenance processes. The main benefit of these technologies is the possibility to monitor, transfer, store, and analyze huge datasets. Based on analysis outputs, there is a possibility to improve current preventive maintenance processes and implement predictive maintenance processes. These solutions lower the downtime, save manpower, and extend the components’ lifetime; thus, the maximum effectivity and safety is achieved. The article deals with the possible implementation of an unmanned aerial vehicle (UAV) with an infrared camera and Radio Frequency Identification (RFID) as two of the smart hangar technologies for airframe condition monitoring. The presented implementations of smart technologies follow up the specific results of a case study focused on trainer aircraft failure monitoring and its impact on maintenance strategy changes. The case study failure indexes show the critical parts of aircraft that are subjected to damage the most. The aim of the article was to justify the need for thorough monitoring of critical parts of the aircraft and then analyze and propose a more effective and the most suitable form of technical condition monitoring of aircraft critical parts. The article describes the whole process of visual inspection performed by an unmanned aerial vehicle (UAV) with an IR camera and its related processes; in addition, it covers the possible usage of RFID tags as a labeling tool supporting the visual inspection. The implementations criteria apply to the repair and overhaul small aircraft maintenance organization, and later, it can also increase operational efficiency. The final suggestions describe the possible usage of proposed solutions, their main benefits, and also the limitations of their implementations in maintenance of trainer aircraft.
