“…Forest lands are located in the centre surrounded and/or attached to the barren lands. This phenomenon might indicate that deforestation occurs to favour the development of agricultural lands [26,27]. The deforestation hypothesis is backed by the image of the barren lands consisting of downed canopy vegetations that construct the forest lands (Figure 6).…”

“…A previous finding said that exclusivity is a critical key to environmental sustainability [2]. It is critical to limit the number of visitors to maintain local sustainability [26][27][28]. To maintain their economic value while maintaining sustainability, the equilibrium of coastal sustainability and tourism profits needs to be estimated.…”

Coastal tourism is a tourism market segment that is increasing in popularity. The said increase happened due to coastal destinations’ ability to give visitors a tranquil and isolated atmosphere. This trend often triggered excessive coastal developments that could strain and cause irreparable damage to the local coastal ecosystem. Previous findings stated that a local environmental carrying capacity assessment needs to be formulated before a physical development can be exercised. Sekotong is a district in West Lombok that has the potential to be developed as a coastal tourism hub. It is located by the Lombok Strait that has good surfing waves and a beautiful seascape. This region is projected to experience a drastic visitor increase in the coming years. These potentials and increasing visitor number projections could attract physical development interests in the future. This study aims to assess local environmental carrying capacity, especially regarding coastal tourism activities. A quantitative approach utilizing statistical data and remote sensing tools is done to assess the physical and real carrying capacity models. The assessment shows that the study area can endure tourism development that is aimed to satisfy 3.087,57 individuals. This number represents the local ecosystem’s limit to endure future development plans and is expected to be referenced in future physical development plans in Sekotong. This study is also hoped to contribute to local coastal environment sustainability.

“…Unmanned aerial vehicles (UAVs) have received extensive attention from the engineering community due to their promising potential in military and civilian applications, such as disaster rescue [1,2], intelligent surveillance [3,4], smart agriculture [5][6][7][8], aerial photography [9,10], mapping [11], industry inspection [12,13] logistics [14][15][16], forest fire-fighting [16], and crop disease monitoring [17][18][19], etc.. Numerous types of UAVs have been fabricated and developed as research platforms, among which the quadcopters (also called quadrotors) are the most popular type because of their considerable merits including autonomous flight, easy construction, simple maintenance, low cost, onboard vision, vertical take-off and landing [20], hovering ability, and manoeuvrability.…”

Objective of this study is to develop a novel, effective, and robust Sliding Mode Control (SMC) method for quadcopters (also called quadrotors) based on Adaptive Neuro-Fuzzy Inference System (ANFIS) for the purposes of enhancing trajectory tracking performance and realizing safe and reliable flight. In the paper, the ANFIS was combined with SMC technology to propose a scheme of adaptive robust controller, which is composed of three sub-controllers, x position controller, y position controller, and z position (altitude) controller. The proposed method can realize position tracking control of quadcopters in the presence of external disturbances. With the help of ANFIS, an adjustable gain rather than a fixed gain was established for the SMC controller, the optimal output could be attained based on a set of rules, and the position control gain was updated by ANFIS, enabling the SMC to adapt to environmental changes. Through modelling, simulation and comparison, experimental data verified that the proposed ANFIS-SMC controller outperformed conventional SMC controller in terms of convergence speed, robustness, accuracy, and stability with a maximum mean error of 0.125 meters in trajectory tracking. Research findings of this paper could contribute to the development of robust and responsive control strategies for Unmanned aerial vehicles (UAVs) trajectory tracking by providing valuable insights into the design of more effective and efficient control systems for UAVs, particularly in the context of dynamic environmental conditions.
