Several studies related to emotion recognition based on Electroencephalogram signals have been carried out in feature extraction, feature representation, and classification. However, emotion recognition is strongly influenced by the distribution or balance of Electroencephalogram data. On the other hand, the limited data obtained significantly affects the imbalance condition of the resulting Electroencephalogram signal data. It has an impact on the low accuracy of emotion recognition. Therefore, based on these problems, the contribution of this research is to propose the Radius SMOTE method to overcome the imbalance of the DEAP dataset in the emotion recognition process. In addition to the EEG data oversampling process, there are several vital processes in emotion recognition based on EEG signals, including the feature extraction process and the emotion classification process. This study uses the Differential Entropy (DE) method in the EEG feature extraction process. The classification process in this study compares two classification methods, namely the Decision Tree method and the Convolutional Neural Network method. Based on the classification process using the Decision Tree method, the application of oversampling with the Radius SMOTE method resulted in the accuracy of recognizing arousal and valence emotions of 78.78% and 75.14%, respectively. Meanwhile, the Convolutional Neural Network method can accurately identify the arousal and valence emotions of 82.10% and 78.99%, respectively. Doi: 10.28991/ESJ-2022-06-02-013 Full Text: PDF

Public Perception and Preference of Loloan Riverbank Recreational Park Sanur. Denpasar is a developing city. Like other developing cities in Indonesia, Denpasar City continues to carry out development in various aspects, one of which is the construction of a recreational park. Servers as a recreational facility and social interaction for the people of Denpasar City. One of the recreational parks being promoted is Recreational Park of Loloan Riverbanks located in Sanur Village. To maximize functionality and improve quality of The Recreational Park Loloan Riverbanks, therefore should be done research on this Recreational Park Loloan Riverbanks to know how perception and preference the community as a user of recreational park. This research used survey method with data collection techniques is observation, interview and questionnaire wich amounted to 30 copies for 30 respondent. Result of people’s perceptions showed Recreational Park of Loloan Riverbanks serves as a cheap recreational place and a cheap sport venue for the people’s of Denpasar City. Result of people’s preference showed addition of recreational park support facilities will lead to increased levels of enjoyment and visitor satisfaction from the Recreational Park of Loloan Riverbank. Public perception and preference of The Recreational Park Loloan Riverbanks used as information and references to the manager or related parties that play a role in managing The Recreational Park Loloan Riverbanks Denpasar City, so that later The Recreational Park Loloan Riverbanks will be liked by the community of Denpasar City.

The ever increasing human population demands more extraction of freshwater to fulfill our basic needs. This put more pressure to the already limited water resource. The previous studies about water governance concludes that local community needs to be actively involved in an integrated water resource management (IWRM) in order to maintain sustainability. Balinese has long been known as community which always preserve water due to their belief in their local wisdom. This article aims to investigate how Balinese local wisdom play its role in the water governance. The social survey study was conducted using descriptive analysis. The data was collected in Badung District of Bali Province with purposive sampling of 100 respondents who live in Badung for the last 10 years and of 17 years old above. The result of the study shows that Balinese may not really aware about Tri Hita Karana and Sad Kertih, but they are practising its principle in their daily life. Balinese respect water as part of nature which must be preserved.
