An Environmental Ergonomics Review of Small Medium Enterprises Workplace Condition in Indonesia

Abstract: Small and medium enterprises (SMEs) have a large contribution to Indonesia's economic growth, however, the productivity of Indonesian SMEs is still relatively low. One of the causes of the low productivity of SMEs in Indonesia is the ergonomics analysis has not yet been applied, especially environmental ergonomics. The owner or company management often does not pay attention to the conditions of the work environment. Besides, there is still very little research in this field. This study is intended to provide an overview of the working conditions of SMEs in Indonesia over the past decade. For this purpose, it was searched for research articles related to environmental ergonomics in Indonesian SMEs published from 2008 to 2018. The search results show that the working environment conditions in SMEs, such as temperature, lighting, noise, relative humidity, air quality, air velocity, and vibration, are almost all outside the specified threshold value. Various efforts need to be made to improve the working conditions of SMEs in Indonesia and encourage SME management to pay more attention to the environmental ergonomics aspects so that the conditions in the workspace of SMEs become healthier, more comfortable, and more productive.

User Interface of Zakat Information System Redesign using Design Thinking Approach. Case Study: KNEKS

Abstract: The realization of the amount of zakat recorded in Indonesia is still very small compared to its potential. This happens because the existing information system has not facilitated and optimized the process of recording zakat in Indonesia by the Badan Amil Zakat Nasional (BAZNAS), Lembaga Amil Zakat (LAZ), and Unit Pengumpul Zakat (UPZ). This research focuses on designing the appearance and features of Sistem Informasi BAZNAS (SiMBA) which is currently the focus of the Komite Nasional Ekonomi dan Keuangan Syariah (KNEKS) in advancing zakat management in Indonesia. The Design Thinking approach is chosen because it is an approach that provides solutions to existing problems and is highly oriented towards user needs (Schallmo, 2018). By using the Empathy Map and Customer Journey Map visualization methods, the Usability Testing scenario test method, and the survey method of the Post-Study System Usability Questionnaire (PSSUQ) in the Design Thinking stage, researcher can provide the most suitable recommendation for the User Interface of the information system to meet the users’ needs.

In the context of national economy, Small and Medium Enterprises (SMEs) has important role, and thus this article tries to elaborate and classify the research of NPD in SMEs, as an effort to gain an insight of this topic. The findings from the study is that dominant research areas on SME's NPD are classified into three major areas: success-failure factors, followed by NPD strategy, and staged process. More emphasis should be put on topics about radical products, ideation and creativity, and the new product development speed.

Exploring Risk and Benefit Factors Affecting User Adoption Intention of Fintech in Indonesia

Abstract: The presence of Fintech as an innovative and disruptive financial service can improve the efficiency and scope of financial services through the application of technology. Fintech is considered to have various benefits. However, based on survey conducted by DailySocial and Otoritas Jasa Keuangan finds that the Fintech adoption rate in Indonesia is still relatively low at around 58.1%, this is in line with a penetration level of Fintech in Asia which Indonesia usage level still in 5% compared to China, Hong Kong, and India. In determining Fintech adoption, users tend to do rational calculations by comparing the perceived benefits and risks and will decide to adopt them when the perceived benefits are greater than the risks received. According to some studies, trust can be mediated to reduce some level of risk, thus this study will also include trust variables in the risk-benefit framework to determine user adoption intention on Fintech services in Indonesia. Based on data collected from 100 Fintech users, this study initially investigated whether perceived benefits and risks significantly impacted Fintech adoption intention. Partial Least Square (PLS-SEM) method is used to estimate the relationship between constructs. As a resulting trust, economic benefit and convenience are proven to significantly influence the user to adopt Fintech. While privacy awareness, financial risk, and legal risk are significantly affected by user trust. The hypothesis testing indicates that security risk has the biggest negative effect and convenience has the biggest positive effect on Fintech adoption intention.

Design Thinking Approach for Mobile Application Design of Disaster Mitigation Management

Abstract: Effective disaster management lead to useful and reliable mitigation program. Mitigation program is an action to reduce the risk to life, property, social and economic activities, etc. from natural disasters. One of the most often disasters that occurred in Indonesia is a tsunami. Tsunami also had a lot of victims, including life victims, house, property, etc. This article focuses on using design thinking method as an approach to developing a mobile application for tsunami disaster management in Indonesia. The first step of the design thinking is empathizing with the user, which we have done by with the victims of the tsunami by interviewing one of the survivors. The second step is defining the user's needs. In the third step, ideation, we are doing brainstorming by using an affinity diagram. After that, we are developing the prototype by developing the beta version of the application to visualize the interfaces. Lastly, in the testing step in validating our mobile application prototype, we visited one of the schools in Banten which had experienced a tsunami disaster. In the end, we are discussing the results including from the pre-test and post-test results from students who had tried our application.

Workplace Design Process at Indonesian Manufacturing SMEs

Abstract: The workplace design process must not be ignored to get a good workplace. A good workplace can support occupational health and safety and comfort of workers while doing work so that it is expected to increase their work productivity. Unfortunately, the environmental conditions of workspaces in most SMEs (small and medium enterprises) in Indonesia do not meet the standards. Besides, production machinery, raw materials, and finished goods are placed irregularly which has the potential to inhibit material transfer. This study is aimed at obtaining an overview of the workplace design process carried out in Indonesian manufacturing SMEs as a first step to finding a suitable workplace design process model for manufacturing SMEs in Indonesia.

The Use of Response Surface Method To Optimize The Ultrasound-assisted Extraction of Moringa Leaves

Abstract: The Ultrasound-assisted extraction is one of the breakthrough in extraction techniques which offered the modest and more effective outcome based on several research influenced by some variables such as temperature, power and frequency, intensity, extraction time, preparation process, type and quantity of solvent. The objective of this study was to assess the effect of the three parameters including extraction time, solvent-to-solid ratio, and ethanol concentration each of which consists of three levels on the percentage of yield, total phenolic content and total flavonoid by using the Response Surface Method (RSM). This research used an ultrasound equipment which was set at frequency 20 kHz, amplitude 32% and the 0,5 of intensity. The experimental design of this research employed 40 runs of Response Surface Method constructed by Central Composite Design (CCD). The output showed that that the percentage of yield about 0.37-9.86%, the total phenolic compound ranged from 27.361-59.907 mg GAE/ml and the total flavonoid result varied from 5.568-67.384 mg/ml. In addition, the more ethanol concentration used the more phenolic and flavonoid content generated, however the yield production decreases. On the other hand the higher the solvent-to-solid ratio creates the high yield yet this variables showing no impact towards two other responses. The result of this study also revealed that extraction time has no effect on all the responses.

Designing Theoretical Framework for Measuring Burnout related to Academic System Amongst University Student

Abstract: Universities have an important role in enhancing the education of a nation, which aligned with efforts to create qualified graduates. In relation to this circumstance, universities generally establish several standards (apart from the national standards established by the Ministry) in their academic systems such as standard of competency, study allocation for each semester, teaching and learning processes, teaching period and any other related standards depend on faculty and/department within the universities. However, those established standards create the amount of demand and/study burden, particularly for students. This paper aims to develop a design framework and present the responsible factors that related to academic systems, by the questionnaires that are designed for monitoring the effect of the academic systems on student burnout during their study. This paper focusing on the relation of student burnout toward the academic system which is analyzed with Partial Least Square (PLS) method. It is expected that the output framework from this paper will contribute in evaluating the academic system on higher education and can be a guide for developing a better academic system within the department university hence improving the quality of student outcomes and prevent burnout.

Technology readiness level assessment of lithium battery in Indonesia for national electric vehicle program

Abstract: Based on the energy consumption and emissions from the transportation section, Indonesia started the National Electric Vehicle Program (Molina) in 2012. The electric vehicle (EV) is made up of a few main components, one of them is the battery. Lithium battery is the main choice for the EV storage system because it is lightweight, has a high storage capacity and electrical conductivity, doesn’t have memory effect, and has a relatively long life cycle. Indonesia’s Ministry of Research and Technology (Kemenristek) initiated the National Consortium of Lithium Battery that focuses on both upstream and downstream research to develop EV lithium batteries domestically. This research aims to assess the technology readiness of EV lithium battery in Indonesia using the Technology Readiness Levels (TRL) method and to identify action items to improve technology readiness using the Importance-Performance Analysis. Results showed that EV lithium battery in Indonesia achieved TRL 5 and action items were derived through a focus group discussion with experts from academicians, the government, and industry.

Improvement of new product development process by evaluating the existing development approach: Lesson learned from pharmaceutical and ICT companies

Abstract: The article discusses the implementation of the NPD process design method, while at the same time considering the existing product development applied by the company, to have early development improvement ideas. It is involving nationwide companies from two industries: pharmaceutical and ICT-related. The approach is using the PDP Design Method and SWOT analysis (as part of the ’existing design process’ analysis). The result shows that using the approach, the improved design ideas are obtained: agility of the process, development time reduction with concurrent approach, lean initiatives, and evaluation of process iterations. Future research can be done related to the analysis of existing product development in the PDP Design Method and the usage of other tools to study the issue. It is also interesting to study this approach for companies that don’t have a "formal" product development process yet.

Knowledge Sharing Strategy for Indonesian Millennial Workforce

Abstract: In a competitive business environment, many companies struggle to align their resources to improve their performance. The resources should become one of the company's competitive advantage. One of those competitive advantages is knowledge assets. Knowledge assets can be developed by optimizing human resource management because not all companies want to invest funds to develop a knowledge management system. Initiation of knowledge sharing behavior among workforces is considered to be one of the most efficient ways. In Indonesia, it is predicted that 46% of workforces in 2020 are millennials. Many previous studies have looked at millennial behavior in the work environment, and they are considered to potentially inhibit the development of the company's knowledge assets due to a high turnover rate. This paper is aimed to explore the factors that promote or discourage knowledge sharing behavior of millennials workforce. Factors studied included psychological, organizational culture, cognitive abilities, technological facilities, and so forth. The PLS method is used to explore these factors. A strategy has been developed as a recommendation for companies to initiate a knowledge sharing culture.

Knowledge Management Framework in New Product Development Projects of Automotive Industries

Abstract: In recent year, industries are faced to the challenges with a dynamic environment. The consumer preferences are subject to changes quickly. New regulations and the climate of competitions among companies stimulate changes at the market placed product. New product development teams are challenged to accelerate their work to shorten product time-to-market. This is due to the product life cycle is getting shorter and to avoid change of preference before the product launched. The new product team's knowledge of the character of the previous product is needed to accelerate the process of developing new products. The involvement of supplier and user in preparing new product should not be forgotten. The knowledge they have about previous products must also be collected. Users may have complaints on the previous product, while suppliers may have difficulties in creating the supply. This paper proposes a knowledge management framework in developing new product in order to improve product quality and shorten time-to-market with involvement of user and supplier perspective. A model was developed based on literature review and expert interview. The proposed model has three dynamic processes: knowledge creation, knowledge diffusion, and knowledge storage. A design structured matrix (DSM) was created to analyze the relationship between stages in the framework. Experts state that the knowledge gained at the end of each project is reused as input to the next project. To test the framework, a case study is planned in an automotive company. Further research is suggested to validate the proposed framework in different industries.

Influence Factor Analysis on Building Material Certification System with Ecolabel in Indonesia

Abstract: These past few years in Indonesia the concept of environmentally friendly products started to become a trending topic among the professionals. One of these indicators is when the Ministry of Industry issued a regulation called "Standar Industri Hijau" hereinafter abbreviated as SIH in 2015. SIH stated that a production process of a product should be environmentally friendly and efficient. Not only green, but the company that wants to adopt SIH should also have a clear social responsibility program. Another regulation is issued by the Ministry of Environmental and Forestry. This regulation is known as "Standar Nasional Indonesia Ekolabel" or simply called "SNI Ekolabel", a regulation that more focuses on the product. But there is a new problem that arises, that becomes a concern through all those professionals. The amount of companies that could adopt or follow those standards is still quite small. Many said that those standards are too rigorous to adopt. Seeing this problem, some of the professionals with the endorsement of some company, establish a Non-Governmental Organization called Green Product Council Indonesia. Green Product Council Indonesia is an NGO that publishes an environmentally friendly certification scheme known as Green Label Indonesia, a less rigorous standard for environmentally friendly products, especially a building material and product. But still, the number of companies that already have been certified to these standards is small in number. Therefore the goal of this research is to analyze the barriers that preventing or the factors that influencing a company to certify its products with ecolabel in Indonesia. The methodology which will be used in this research is the Structured Equation Model (SEM).

Biomechanics analysis on the human gait to attribute the energy floor design with inverse dynamics model approach

Abstract: Currently, the building and construction industry play an important role. However, development practices recognized as one of the main contributors to environmental problems especially in the production of electrical energy. Faculty of Engineering Universitas Indonesia (FT UI) is one of the largest on-campus electrical consumption of the UI. Because of that, needs an alternative energy to reduce the operational costs of the FT UI. One of them is with utilization of Ground Reaction Force (GRF) on the activity of walking as an alternative at FT UI. Based on the results of previous study, the value of GRF and the potential energy of human gait (walking) on the floor height change as deep as 5 cm yield the greatest value. Therefore, the need for analysis of biomechanics in human gait as design attributes of energy floor (elevation changes on the floor) with inverse dynamics model to find out the level of comfort on the human gait to the floor height of the dynamic factor by doing the calculation of knee and ankle joint moments. Based on the results that the average value of joint moment male Indonesian that walked on the dynamics floor has a value of 5 cm smaller that static floor. In summary, the comfort level can be summed up in the joint segment of the leg and foot were still comfortable conditions when walking on the dynamics floor of 5 cm.
