Anugrah Kusumo Pamosoaji,Augie Widyotriatmo,Keum-Shik Hong 제어로봇시스템학회 2010 제어로봇시스템학회 국제학술대회 논문집 Vol.2010 No.10

A motion planning algorithm for a nonholonomic vehicle in triangular regions is investigated. The regions are the result of splitting a larger and complex workspace, and are classified into three classes, that are, empty regions, obstacle-inside regions, and goal regions. The vehicle has to achieve a goal configuration from any initial configuration in the workspace. A set of procedures to generate velocity vector fields by utilizing vector potential functions is proposed. The vector fields are categorized as those generated by the edges of regions, obstacles, and goal points. To deal with some constraints, i.e., maximum velocities, a set of parameter-scaling rules is provided. A state-feedback controller for a unicycle vehicle is used to show that the generated motion plan can be tracked by the vehicle. Simulation results showing the motion planning from different initial configuration are presented.

Purpose - The purposes of this research are: (1) Building and testing a research model that integrates Theory of Reasoned Action (TRA) with fear, perceived risk, and health protocols; (2) Examining the impact of compliance with health protocols on consumer behavior when offline shopping. Research design, data, and methodology - The data collection uses the self-administered survey method, and the questionnaire is distributed online. A total of 504 Indonesian population aged 18 years old or more participate in this research. Data are analyzed using factor analysis, multiple regression, and multiple regression with interaction. Result - This study reveals several findings: (1) Attitude and subjective norm have a significant effect on offline shopping behavior; (2) fear has a direct and indirect effect on offline shopping behavior; (3) the effect of perceived risk on the intensity of offline shopping is determined by compliance with health protocols. Conclusion - This paper discusses the direct influence of attitudes and subjective norms on behavior. This research also integrates fear, perceived risk, and health protocol factors in TRA, which may not have been done much, especially in the COVID-19 pandemic context.

Hardius USMAN,Nucke Widowati Kusumo PROJO 한국유통과학회 2022 Asian Journal of Business Environment (AJBE) Vol.12 No.4

Purpose This research develops the expanded Technology Acceptance Model (TAM) to investigate the relationship between perceived usefulness and perceived ease of use with satisfaction and loyalty by considering the role of sharia compliance, commitment, and trust. Research design, data and methodology: A data source is 300 respondents from a self-administered survey. The target population is Muslims who are customers of Islamic banks, with age at least 18 years, and used e-banking to make payment transactions. The analysis methods are MANOVA and Multiple Linear Regression. Results: The results suggest that intention to use and actual behavior variables are replaced with satisfaction and loyalty. Commitment is not recommended, while trust is an explanatory variable that can be used as an external variable. Conclusions: It is important to increase satisfaction and commitment also concentrate to various aspects of sharia compliance to increase customer’s loyalty to use e-banking. The fulfillment of sharia compliance by Islamic banks will increase the Islamic bank customers loyalty.

Hardius USMAN,Nucke Widowati Kusumo PROJO,Ika Yuni WULANSARI,Thasya FADILLA 한국유통과학회 2021 Asian Journal of Business Environment (AJBE) Vol.11 No.3

Purpose: The purpose of this research is to study the role of life satisfaction, quality consciousness, and religiosity, which are integrated with the TRA Model to explain the switching intention of Muslim consumers to use Halal Cosmetics and Personal Care (HCPC). The second purpose is to investigate the relationship between variables used in this study to provide recommendations to HCPC producers about Muslim consumer behavior in the market. Research design, data, and methodology: The target population in this study is Muslims who live in Greater Jakarta. Data collection is carried out by the self-administered survey method based on the Purposive sampling technique, and the questionnaire is distributed online. The statistical analysis to test the research hypotheses is the Partial Least Squares - Structural Equation Model (PLS-SEM). Results: Life satisfaction, product quality consciousness, and religious commitment have a significant effect on attitude to switching but do not significantly influence the intention of switching to use HCPC. Conclusions: Life satisfaction, quality consciousness, and religiosity that represent individual factors indirectly affect the intention to switch to use HCPC. Thus, religious commitment influences attitude to switching both directly and indirectly.

Sensor-based path generation for unmanned autonomous forklift subject to kinematics and dynamics constraints

Zheming Cao,Anugrah Kusumo Pamosoaji,Keum-Shik Hong 대한기계학회 2009 대한기계학회 춘추학술대회 Vol.2009 No.5

In this paper, we will implement polar polynomial curve (PPC) to produce a continuous-curvature path to guide an unmanned autonomous forklift from an initial to a final position in an unknown environment. Generalized polar polynomials are thus obtained which yields the path for fast motions. Important properties of the polynomials are shown and their use provides a method for computing the best motion consistent with the constraints. The approach is used for a forklift's dynamic model. The simulation result of the approach will be shown.

Diversity of Indonesian offal-based dishes

Indonesia is a home to diverse ethnicities and cultures that have infuenced its culinary tradition. Moreover, Indonesian culinary tradition is shaped by the country’s wealth of natural resources, one of which is ofal (including tripe, lung, intestine, liver, and so on). The utilization of ofal has created myriad recipes of ofal-based dishes (OBDs), resulting in a culinary diversity across the nation. Therefore, this article aimed to identify and create a culinary profle of Indonesian OBDs based on geographical distribution. To strengthen this culinary profle, historical creations of Indonesian OBDs were also elucidated. For centuries, Indonesian OBDs have been shaped by several factors, such as natural resources, history, religio-cultural, and economic backgrounds. For instance, specialties such as momoh (braised ofal) from Central Java and pallubasa (coconut milk-based ofal soup) from South Sulawesi were developed due to religio-cultural and economic reasons, respectively. Although 139 Indonesian OBDs are widely distributed across 23 Indonesian provinces, the foods are mostly concentrated in West Sumatra (31 dishes), Central Java (18 dishes), and East Java (14 dishes). Furthermore, intestine, liver, and tripe are the most commonly used types of ofal as utilized in over 40 dishes; while cattle, water bufalo, and chicken are the most utilized sources of ofal. Meanwhile, pig ofal is only used in the non-Muslim regions of Indonesia. The creation of Indonesian OBDs is also infuenced by foreign cultures. For example, gulai tambusu (intestine curry) from West Sumatra, rabeg (Bantenese-styled mutton curry) from Banten, babat gongso (stir-fried cattle tripe) from Central Java, and the ubiquitous sop buntut (oxtail soup) demonstrate Indian, Arabian, Chinese, and colonial infuences, respectively. However, OBD such as saksang (pork stewed in pig blood), which originated from Batak ethnic group, retains the native culinary features. Additionally, OBDs recipes involve several spices, herbs, and other ingredients that can maintain and improve their organoleptic attributes.
