The numerous cases of academic procrastination of students in various universities in Indonesia are worrying. In terms of intervention, there is a proven effective approach to improve students’ skill to cope with academic procrastination. It’s called Guidance and Counseling Gestalt Prophetic (G-Pro). Unfortunately, due to a lack of access, G-Pro needs to be developed. This article will present a new approach called E-Counseling Gestalt Prophetic (E-G-Pro). The author used the Borg and Gall model research and development (R & D) model with three research steps: a preliminary study, model development, and model validity.  Focus group discussion (FGD) has been done to assess the properness of the model. Four parties, each from information and technology expert, Qur'anic Interpretation expert, Islamic education and religiosity expert, guidance and counselor expert, and counselee, were invited to the FGD. Based on internal judgement by experts and users, the E-G-Pro is highly feasible to be applied to help students cope with academic procrastination in Indonesian Islamic Higher Education.

The study was aimed for developing a learning model of Bahasa Indonesia based on local intercultural politeness to improve the foreigners’ communicative competencies. This is Research and Development, started with a preliminary study of intercultural learning concepts and Buginese politeness strategies; the distribution of the needs analysis instruments to the 25 foreigners learning Bahasa Indonesia in Makassar, South Sulawesi, Indonesia; model development, focus group discussions; the model finalization and  product experiment. The interviews and questionnaires data were analyzed by descriptive quantitative and qualitative. The result, a local politeness intercultural learning model consisting of four phases: noticing, comparing, reflecting, and interacting.  1) The foreign learners noticed the use of local politeness markers in Bahasa Indonesia; 2) They compared the similarities and differences between the use of the markers of local politeness and those they found in their native languages; 3) They reflected themselves; 4) They practiced Bahasa Indonesia through direct interactions. The conclusion showed that the t-score = 3.26 > t-table = 2.45 signifying that the model was effective in overcoming the foreign learners’ problems in oral interactions and improving their Bahasa Indonesia communicative competencies.

Abstract This paper presents a one-dimensional analytical model of the ram extrusion process of a powdered material and a procedure for optimizing the shape of the extrusion die. Powdered coal mixed with water and asphalt was used as the extrudate material in the model development. The analytical model relates the pressure at the entrance of the die to the exit pressure of the die. Certain key parameters of the model were obtained from experiments. The comparison of the inlet pressure derived from the analytical model and the value obtained from the experimental procedure shown a good agreement. Optimization algorithms were applied to generate the ideal die shape. The objective is to minimize the power consumed in the extrusion process, while maintaining maximum strength for the extrudates. It is concluded from the study that the model and the optimization procedure developed for the model can be used in extrusion studies of other powdered materials.

Electromechanical Brake

This paper presents a detailed analytical model development which can describe the dynamic behavior of the electromechanical brake-by-wire (BBW) system over the entire operating range. The complete model has 10 degree-of-freedom (DOF) and includes essential nonlinearities such as gear backlashes, Coulomb frictions, and disk gap clearance. Such a full model is reduced to 6 degree-of-freedom model in SIMULINK for simulation study of the effectiveness and the achievable performance of different hardware and controller designs, an invaluable tool in the early design stage of a product. Simulation results show that the model is able to reproduce various nonlinear characteristics including typical structural hysteresis as shown in real brake assembly. The linearized version of the full nonlinear model is then obtained for its modal properties to understand the modes that are critical to the low frequency dynamics of the overall system. The results of the modal analyses are subsequently utilized to obtain two simplified models, one for non-contact mode and the other for the contact mode of operation. The concepts of two simplified models well capture the dynamic characteristics of the system over the frequencies of interest and are being used in the controller (e.g., clamping force control) and estimator (e.g., gap clearance estimation) designs that are under investigation.

Purpose – The purpose of this paper is to show that project success is dependent on the project management approach selected, relative to the challenges posed by the project, and to develop an analytical model for analyzing the performance of the project organization. Design/methodology/approach – The research is based on literature review, model development, interviews, and case studies. Findings – The findings define two different approaches in project management: The prescriptive approach focusses on the formal qualities of the project organization, including governing documentation and procedures. The adaptive approach focusses on the process of developing and improving a project organization, project culture and team commitment. The two approaches have been identified through studies of three different case projects. An analytical model, referred to as the Pentagon model, has been applied for analyzing the performance of the project organization and explaining the project management approach. The model focusses on five different organizational aspects: structure, technologies, culture, social relations and networks, and interaction. Research limitations/implications – The research is limited to megaprojects and to project management success. Practical implications – It is suggested that project teams consider and select their project management approach at project initiation, and accordingly decide on relevant success factors to focus on. The adapted Pentagon model can be applied to develop the project management organization and assess its performance in the course of project delivery. Originality/value – The contribution of the research is the application of the analytical model, and the identification as well as illustration of the prescriptive, vs adaptive management approach.
