Glidding System for a Fixed Wing Aircraft Using PID Control Algorithm Budhy Setiawan, Dekki Widiatmoko, Indrazno Siradjuddin, Supriatna Adhisuwignjo, Ferdian Ronilaya, Mokhammad Syafaat State Polytechnic of Malang Abstract In each unmanned vehicle (UAV) task, the power used is limited. UAVs are often forced to land when the battery runs out before the mission is completed. The gliding controller is proposed in this paper so that Fixed Wing Aircraft (FWA) can fly with minimal power and can adjust direction, altitude, zero pitch and zero roll stability. The FWA uses a BMP sensor at the tip of the wing to detect the difference in pressure experienced by both wings, therefore, the direction of the wind can be determined. The information of the wind direction was then used to maintain the desired altitude of the FWA. The PID control algorithm was implemented to stabilize the FWA altitude to keep cruising or flying in a flat position. Real-time experiments using FWA have been conducted. It can be observed that the FWA was able to air with automatic glider mode for almost 2 minutes. Tests carried out include altitude data, roll and pitch movement from BMP120 sensor readings, The glidding performance has been observed with respect to the altitude, roll and pitch errors. It was measured that the altitude, the roll and the pitch errors were 1.74%, 0.23% and 0.34%, respectively.

Exploitation of Natural Materials Energy in Eastern Indonesia and Efforts to Fight for the Sovereignty of Local Communities Frederikus Fios Character Building Development Center, Computer Science Department, School of Computer Science, Bina Nusantara University, Jakarta, Indonesia 11480 Abstract One form of development activities carried out by humans is the exploitation of natural materials energy. Often the activity of exploiting natural material energy is only oriented to human interests, but ignores aspects of sovereignty (autonomy) of nature and the future of members of the local community of exploitation place. This paper shows field observations and literature reviews on the practice of energy exploitation of natural materials in Eastern Indonesia, which lacks attention to the dimensions of the balance of nature and the interests of local communities. Eastern Indonesia has not prospered because it is still struggling to obtain their sovereignty in the exploitation of natural materials in their own land. Often social conflicts arise due to the exploitation of material energy carried out. The research method uses interpretative analysis and philosophical reflection to get meaning. Research found a theoretical model that is useful for overcoming the problem of exploitation that occurs. Those humans must transform themselves into ecological human beings so that they can bring practical benefits to the good of nature and East Indonesia local people towards the vision of sustainable development.

Building Awareness of Eco-Centrism to Protect the Environment Frederikus Fios Character Building Development Center, Computer Science Department, Bina Nusantara University, Jakarta, Indonesia Abstract The environmental crisis that hit the global world has threatened the future of the human being and all living in the world. The root of the environmental crisis today that is due because of the "human factors". Human mindset embodied in various forms of exploitation of the natural act of damaging our environment tragically. Understand anthropocentric is so permeated human thought patterns stimulate human passion to continue to exploit nature without human arbitrarily. Natural objectified and regarded as a place to suck it for the benefit of human. And nature environment needs to be protected by human as moral person. One way to protect nature is not a great design technology, but change the mind set of people from anthropocentric paradigm to eco-centrism awareness in order to protect the environment entity. Using reflection methods especially deconstruction of Derrida, continuously critical of anthropocentric is a must as one way to protect the environment in theoretical thinking frame. Through this frame of thinking, it can constructed the concept of ecological awareness for protecting environment and the good condition to the earth and all reality of life.

Jakarta, Indonesia. cahyadi-setiawan[at]unj.ac.id Abstract After hundreds of years experiencing a dormant period, Mount Sinabung erupted again in August 2010 to the last recorded in June 2018. Within eight years, significant land cover changes were seen in the area around Mount Sinabung. This study aims to analyze changes in affected areas using satellite imagery. The spatial analysis method is used to determine changes in various land cover. High-resolution images before the 2010 eruption and the latest recording images of 2019 are used as analytical material. The analysis shows that the affected area is in east-southeast and south-southeast directions of the peak of Mount Sinabung. In the east-southeast direction, the eruption material reaches 3.5 km and 4 km in the south-southeast with an area more than eleven thousand hectares. Some villages such as Bekerah, Simacem, and Suka Meriah have even been lost covered by material from the eruption of Mount Sinabung. The area is generally covered by pyroclastic materials in the form of ash, sand, lapilli, and bombs. Most of the areas affected by the eruption are plantation areas, then forest areas and settlements areas. Sinabung Eruption in recent years has had a very significant impact on various aspects, one of which is land cover.
