Unpacking Critical Dimensions of Service Quality in Tertiary Institutions in South Africa- The Case of University of Kwa-Zulu Natal


Pages 1-6
Vannie Naidoo

As service marketing has evolved over time, more research has been conducted on quality and how it impacts on the customer. Since tertiary education forms part of service marketing it is important to identify critical dimensions of service quality and understand how it affects the students within the university environment. The new millennials are students that are demanding. Their choice of university is based on how they perceive the university brand and reputation, how they view the quality of the programs on offer at the various faculties and how they view the non-academic, support services provided at the university such as the housing, administration, exams, canteen services to name but a few. To attract the new millennial student the University of KwaZulu- Natal uses excellence in service quality to set itself apart from other universities in South Africa. In this study student perceptions on service quality will be identified and the critical dimensions of quality namely tangibles, reliability, responsiveness, empathy and assurance will be discussed. The SERVQUAL instrument has been adapted to tertiary institution environment and used by the researcher to measured service quality the students within the five campuses of the University of Kwa-Zulu Natal. The findings of the study recorded that students were dissatisfied with the service offerings made to them at the universities five campuses. Possible recommendations to assist in closing the quality gaps found in the critical dimensions of service quality for the student respondents have also been put forward.

Conducting General Meeting of Shareholders when the Terms of all Members of Board of Directors and Board of Commissioners Expired; A Perspective from Indonesian Law


Pages 7-12
Widjaja, Gunawan

The research tried to elaborate all the possibilities in conducting a General Meeting of Shareholders (“GMS”) in a Corporation established under the Law No.40 Year 2017 regarding Corporation (the “Corporation Law”) when the terms of all the members of the Board of Directors (BoD) and Board of Commissioners (BoC) of the Corporation expired. The Corporation Law kept silent on how to conduct a GMS when the terms all the members of the Board of Directors (BoD) and Board of Commissioners (B0C) of the Corporation expired; meanwhile there were many incidents in practice. Therefore in order to make the GMS possible a legal research must be conducted. This research is a normative legal research. It used secondary data, which included primary legal sources, secondary legal sources and tertiary legal sources. Data were collected through literature review and analysis was made using qualitative approach. Findings and analysis indicated that there were several ways to conduct the GMS whenever the terms all the members of the Board of Directors (BoD) and Board of Commissioners (B0C) of the Corporation expired. Finally the researcher also provided recommendation to shareholders to avoid such a situation in the future.

Pages 13-22
Eddy Nurmanto, Dedy Sushandoyo, Togar M. Simatupang

This conceptual paper examines value co-innovation architectures emanated from multiple actors in cooperatives. The study is aimed at providing a theoretical contribution to the literature on value co-innovation particularly on proposing a theoretical framework on how the process of value-based innovation takes place when multiple actors are involved. The study is designed to employ a mixed-research method that combines a qualitative research method and agent-based modeling. The qualitative research method uses a comparative case study approach to investigate how value co-innovation arises from multiple actors including their social complexities, which are reflected in different roles, views and interests of involved actors. The investigation is expected to shed light on how contexts influence value coinnovation architecture of the studied cooperatives. The chosen cases are three cooperatives in the West Java province of Indonesia. Koperasi Peternak Susu Bandung Selatan (KPBS), Koperasi Wirausaha Baru Jawa Barat Sejahtera (WJS) and Koperasi Baru. The agentbased modeling is used to explore and understand dynamics complexity among the actors involved in the process of the value co-innovation. The expected result of the modelling is in a form of several types of value co-innovation architecture including the contexts where they are appropriately applied. The expected results of this study can be used as a guidance for practitioners and policy makers as efforts in creating, delivering, capturing and communicating new values among the involved multiple actors.

Rosa Fitriana


The issue of Corporate Social Responsibility is increasingly discussed in recent decades and Corporate social responsibility disclosure grows widely in Indonesian business even in many other countries. Corporate Social Responsibility shows responsibility and awareness to the entity operate of a company from its economic, social and environmental benefits for all stakeholders. CSR purposes drive company to change the entity goals that contribute to the sustainable development. The researches on corporate social responsibility disclosure find many different results greatly because of differs in company and country. This study is aimed to explain the influence of institutional ownership, profitability, and size company to corporate social responsibility disclosure. This study is a descriptive and statistical analysis technique. There are 30 samples applying purposive sampling technique. The sample in this study is Indonesian manufacture companies listed in 2010-2013 whose annual reports disclose corporate social responsibility activities and can be accessed at Indonesian Stock Exchange website. The results of this study show that there is significant influence between institutional ownership to corporate social responsibility disclosure. Positive significant influence on profitability and size corporate to corporate social responsibility disclosure are found. In this research was suggested for the company, they can make the sustainability report continuously as a responsibility with full realized for sustainable development of the company and have a great division of corporate social responsibility. For the government can have more attention about corporate social responsibility with have an organ that focuses on corporate social responsibility, make a rule about corporate social responsibility disclosure for the company and the sanction for the company that disorderly the rule. For the next researcher can be used the sustainable development of the company, the effectiveness of the corporate social responsibility disclosure as a new variable, then widened the sample with extending the research period or widened the scope of the company.

Adi Budipriyanto, Budisantoso Wirjodirdjo, Nyoman Pujawan, Saut Gurning

Berth, quay crane and yard are the main resources of the port that determine the level of service quality provided to shipping lines. In this paper, berth, quay crane and yard allocations are considered simultaneously. Scenarios are made to determine the effect of these factors. The scenario is based on the combination of each level of each factor. Each scenario is simulated to measure the response assessed based on turnaround time.The authors develop a simulation model to investigate the impact of berth, crane, and yard allocation simultaneously. Simulation model was developed to see the impact of simultaneous allocation and collaborative strategy, especially the impact on waiting and turnaround time. The authors develop 16 scenarios from a combination of berth, quay crane, yard and strategy. Author uses two terminals in Jakarta, Indonesia, is the Koja container terminal (TPK Koja) and Jakarta International Container Terminal (JICT).The results show that simultaneous-collaborative allocation can reduce waiting and ship turnaround time. Simultaneous-collaborative strategy reduces waiting time and turnaround time significantly, improving service level to shipping lines.

To study the effect of friction temperature on transfer film formation in organic brake pads, friction tests which were comprised of 100 consecutive braking under constant temperature of 300℃, 400℃, 500℃ and 600℃, respectively, were conducted. The organic pad material was manufactured to contain 15% of fiber material which included aramid fiber and mineral fiber, 14% phenol resin with abrasive component of 9% Fe3O4, and lubricating component of 8.5% SnS2. Counterpart disks used in the friction tests were collected to examine the formation of transfer film on the disk surface. The transfer film formation turned out to be very dependent on friction temperature, and the film thickness as well as the fraction of area that is covered with transfer film increased with increase in temperature. The chemical composition of the transfer film assured that the film material was mostly from the pad. The active formation of transfer film at 500℃ and 600℃was believed to be due to thermal decomposition of phenol resin or aramid fibers which constitute the pad material. Friction test results showed that the friction coefficients tended to decrease with repeated braking, which was probably due to successive development of transfer film with repeated braking. Thus, the role of transfer film turned out to lower the friction coefficients, which is in accordance with the result of our previous researches.

KwangHo Song, Yoo-Sung Kim

Automatic pornography detection is important to make a safe and clean online contents distribution environment. In this paper, therefore, we propose the new pornographic video detection scheme using video descriptor which made by re-trained convolutional neural network (CNN) by transfer learning which used for image descriptor generation. This model use a part of re-trained CNN architecture, VGG-16, to generate image descriptor of video frame. In subsequently, single video descriptor is made by fusing image descriptors by pooling method on each video. Based on these video descriptor, we train support vector machine (SVM) to classify the pornographic frames. As a result, the average accuracy is 99.6% and this is a higher figure from at least 3% up to 7% more than other previous works.

In this paper, the construction process of the INHA Vehicle Database which can be used for developing of a Vehicle Maker & Model (VMM) Classifier is introduced. In order to develop a vehicle detector and/or VMM Classifier with the machine learning technology for the public participated social security service or Intelligent Transportation System, a large volume of vehicle images and ground-truth data acquired from various surveillance cameras and environments should be obtained. For such purpose, fixed CCTV cameras, dash-cams attached to operating vehicles, and smartphones are being utilized for recording vehicle videos. From these vehicle videos, about 162,000 vehicle images and ground-truth data are being created in a month using INHA-VAS(Video Annotation System), for the INHA Vehicle Database. Constructed database will contain twice more of the actual vehicle images compare to other vehicle databases previously constructed.

Untreated tofu wastewater is an organic waste that has very high COD and TSS, 7771,3 mg/L and 840,5 mg/L respectively. This high pollution parameters may endanger the environment if the wastewater is discharged to it. In order to prevent that damage, these pollution parameters have to be reduced with an effective treatment. In this research, a tofu wastewater was treated using a combination method of plasma electrolysis and coagulation-flocculation with 1% chitosan solution as the coagulant. Coagulation-flocculation method was used for wastewater pretreatment because it could reduce the high pollution parameters in tofu wastewater while plasma electrolysis could reduce them to their smallest concentration. The best chitosan volume for reducing TSS to 74,4% was 20 mL while the best volume for lowered COD to 16,8% was 40 mL. Plasma electrolysis was the next step for tofu wastewater degradation, it could drop the value of COD of tofu wastewater to 36% during 60 minutes process at 2000 mg/L as the initial concentration of the wastewater.
