    Authors: Sri Supatmi, Rongtao Hou, Irfan Dwiguna Sumitra

    DOI: 10.1155/2019/6203510

    Abstract

    An experimental investigation was conducted to explore the fundamental difference among the Mamdani fuzzy inference system (FIS), Takagi-Sugeno FIS, and the proposed flood forecasting model, known as hybrid neurofuzzy inference system (HN-FIS). The study aims finding which approach gives the best performance for forecasting flood vulnerability. Due to the importance of forecasting flood event vulnerability, the Mamdani FIS, Sugeno FIS, and proposed models are compared using trapezoidal-type membership functions (MFs). The fuzzy inference systems and proposed model were used to predict the data time series from 2008 to 2012 for 31 subdistricts in Bandung, West Java Province, Indonesia. Our research results showed that the proposed model has a flood vulnerability forecasting accuracy of more than 96% with the lowest errors compared to the existing models. © 2019 Sri Supatmi et al.

    The Contribution of Stress Management and Good Employee Performance Towards the Success of a Company

    Abstract

    Introduction:

    Today, factors which drive a company’s success are basically workers’ personality and one of the factors affecting work is self-management, which includes stress management. It is this factor which can later influence the performance of a worker within a company.

    Aims:

    In this case, the present study aimed to examine the contribution of personal stress management to an employee’s performance and how such influence may affect a company’s success. The main focus of this study was to evaluate stress management and its effect on employees’ performance. This study took place in Bandung at organization X and we applied a descriptive survey method as the most appropriate means of the study. The participants were purposively selected comprising 34 employees.

    Conclusion:

    The results revealed that there are many stress factors employees endure though they don’t significantly affect performance, but still influence most of their decisions to leave the company due to continuous dissatisfaction. It is therefore recommended that such a company should establish a most appropriate strategy to prevent stress within its employees.

  • Predictors of Life Aspirations’ Fulfillment as an effort of Social Workers to Improve the Living Standards of Rural Community

    Authors: Dewi Kurniasih ; Yudi Rusfiana

    DOI: –

    Abstract

    With prevalent poverty, poor health conditions, limited economic possibilities, and limited access to education, rural people are deprived of most of life’s fundamental essentials. Several social organizations have recognized these potential problems and are attempting to improve rural communities. Considering the importance of social organizations in enhancing the living standards of rural communities, the current study investigates the role of social workers, i.e., rural familiarity and interest, social connections, and place integration, in enhancing community participation and satisfaction, thereby enabling individuals to realize their life goals. A quantitative research approach was utilized to collect data from 480 socially low-income families in rural communities in the Indonesian provinces of South Kalimantan and Banjarmasin. By statistically evaluating the obtained data, it was shown that social workers’ traits were vital in providing rural communities with employment prospects by beginning various programs to encourage their involvement and contentment with such projects and activities. Their higher degree of happiness and participation led to realizing their life goals. This study contributes to the existing sociology literature by giving empirical evidence about the role of social workers in enhancing the fulfillment of life aspirations in rural communities, resulting in higher living standards. © 2022, Oxbridge Publishing House.

  • An Autonomous Parking System using the Hybridization of the Rapidly-Exploring Random Trees Star and Ant Colony System

    An Autonomous Parking System using the Hybridization of the Rapidly-Exploring Random Trees Star and Ant Colony System

    Authors: Muhammad Aria ; Jana Utama

    DOI: https://doi.org/10.37934/araset.31.1.291297

    Abstract

    One key autonomous driving car application that can be utilized to address the problem of parking spaces is autonomous parking. The goal of this study is to develop a path planning algorithm that can swiftly create a path for autonomous parking in a variety of car parking settings. The method employed is a mix of Rapidly Exploring Random Tree Star and Ant Colony Systems (RRT-ACS). The RRT-ACS method can quickly provide an ideal path. The reed sheep planner technique is also used to provide a smooth curving path that non-holonomic vehicles can follow. The performance of the RRT-ACS algorithm-based autonomous parking system is compared to that of the RRT*-connect and informed RRT*-connect algorithms. The simulation tests were performed in common parking settings such as parallel parking and vertical parking. The test results reveal that the suggested autonomous parking system outperforms other comparative algorithms. It is possible to infer that a route planning algorithm capable of rapidly designing a path for automatic parking in a variety of car parking circumstances has been successfully built. These findings may have ramifications for self-driving cars equipped with advanced driver support systems.

    Keywords: Autonomous system, RRT-ACS, parking
