Natural minerals such as zeolite are local natural resources in the various regions in Indonesia which has application as a filler, bleaching agent, or dehydration agent. It also has function as green catalysts material for biomass conversion into bio-fuel. The trend movement of green and sustainable chemistry research that designing environmentally friendly chemical processes from renewable raw materials...
In behavior based robotics, development of behavior coordination method is very important. Fuzzy behavior coordination (FBC) can be used here, but it still have weaknesses, because it can result in slow robot movement, too long time to reach the target and fail to avoid trap. In this paper, modification of FBC, by combining it with subsumption architecture, is proposed to overcome those weaknesses...
This paper proposes hybridization of fuzzy Q-learning and behavior-based control for autonomous mobile robot navigation problem in cluttered environment with unknown target position. The fuzzy Q-learning is incorporated in behavior-based control structure and it is considered as generation of primitive behavior like obstacle avoidance and target searching. The simulation result demonstrates that the...
The research of legged robot was rapidly developed. It can be seen from recent ideas about new systems of robot movement that take ideas from nature, called biology inspired. This research focused on five legs robot that inspired from sea star (phylum echinodermata). For cluttered environment, it is necessary to uses more than one learning module to control navigation of five legs robot. This paper...
AbstractThis study examined the photosynthetic acclimation of pre-existing Shorea johorensis (Dipterocarpaceae) seedlings to the change in conditions that occurs at the time of logging in Central Kalimantan, Indonesia. The hypothesis was that the seedlings would be unable to acclimate beyond partially open conditions after canopy disturbance caused by logging, therefore limiting the potential for...
