Abstract

Most wheelchairs circulating in Indonesian market are imported from China at affordable prices, but do not fufill the ISO 7176 series standards. SNI 09-4663-1998 about wheelchair is one of medical devices standard. The standard is considered do not covers the quality and user safety, while wheelchair technology is transform rapidly. Mapping and analyzing gap between stakeholder need and SNI 09-4663-1998 is expected to be input of standard review to improve the competitiveness of products. This research using the Zachman Framework approach following FACTS steps. Data collection uses the observation, in-depth interviews and Focus Group Discussion. Data analysis using Inter Rater Reliability (IRR) which to measure the level of agreement of respondents. The results showed that stakeholder technical needs included 7 parameters: stability, maneuverability, mobility, dimensions, strength, durability, and product information. SNI 09-4663-1998 only includes the product strength parameters through a drop test so that the standard needs to be reviewed.

Abstract

The hip joint is one of the most often used joints by humans in their activities. The hip joint can be impaired if an accident or an illness such as osteoarthritis-affected. It makes the patients need to get implants to restore their productivity. The implant must be biocompatible, bioactive, and have high strength and resilience to prevent damage. The implants in this study were made from 304 Stainless Steel. One of the stages in making implants is the electroplating process. The electroplating method implemented is hard chrome. Some operating conditions that are considered to affect the electroplating process and are used as independent variables are the concentration of chromic acid, electrical voltage, and length of coating time. This study aims to Optimization of Electroplating Thickness Quality at Hip Joint Implant. This study uses the Taguchi method to design the experiment and to obtain the optimum electroplating thickness results. ANOVA is used to obtain the influential prediction of the significance level. Process ANOVA was helped Minitab 16. Based on the ANOVA, it is known that the most significant factor for the electroplating thickness is the concentration of chromic acid, the voltage, and the least influential factor is the electroplating time.

Abstract

SPAM (Sistem Pengolahan Air Minum or Drinking Water Treatment System) UNS was established in 2015 to meet the drinking water needs of the UNS academic community by providing 129 dispensers and water tap machines spread across buildings at UNS. A survey conducted by UNS students in 2017 showed that 54 % of students were not sure of the quality of UNS SPAM water. So the service quality questionnaire was distributed to 160 UNS students randomly and it was found that only 3 % of respondents stated that they used SPAM UNS water dispenser very often. Processing results shown the highest gap value is in the reliability dimension, with CTS namely cleanliness and flow of water. From the survey regarding the cleanliness and flow of the water carried out the DPMO value of the process was 332,589 (1, 930 sigma) . Recommendations for improvement are in the form of several SOPs to improve the cleanliness and quality of SPAM UNS water dispenser services.

Abstract

The advancement of science and technology in the world has brought many influences to the changes in people's behavior and habits, one of that is the technology payment system adopted as an electronic payment system. As an electronic payment instrument, OVO cooperates with one of the online-based transportation services, Grab. However, the success of a company can be seen from the quality of service in meeting the satisfaction of the community or customers. The success of the company in providing quality services can be determined by the Service Quality (Servqual) approach, that is a method used to measure service quality from the attributes of each dimension, so that a gap value will be obtained that is the difference between consumers' perceptions of services that has been received in the hope that will be received. The objective to be achieved is to propose a design in the form of alternative solutions for the priority of improving the quality of electronic money OVO services in Grab applications. Data were collected through a questionnaire using non-probability sampling techniques with a total sample of 140 respondents. The study found the main problems, namely in the dimensions of compensation, responsiveness, and Privacy/Security.

Abstract

Background: There is a high demand for wheat flour, but the supply of it is reduced due to high prices and world oats availability because of climate change and conflicts. Cassava is processed through a fermentation process into mocaf flour and can be used as an alternative substitute for wheat flour. However, the availability of cassava has decreased in the last five years. Purpose: This research aims to determine the factors that influence the availability of cassava by considering sustainability. Design/methodology/approach: This research uses primary data from the Mocaf agro-industry and secondary data from the Central Bureau of Statistics website, as well as previous research. Supply chain management is used in this study with a model simulation of a dynamic system. The simulation model begins by creating a Causal Loop Diagram (CLD), building a mathematical model to formulate relationships between related entities, developing a Stock Flow Diagram (SFD), and drawing the model with Stella Software.Findings/Result: The results show that the factors that influence the availability of cassava as raw material for mocaf are harvest growth and an increase in the purchasing price of cassava at the farmer level. The simulation results show a substitution policy of 30% and cassava harvest growth of 1% every year, with the total availability of cassava being 17 million tons. The sustainability factor which refers to the simulation results, namely from the environmental dimension, can reduce CO2 emissions. The social dimension is the absorption of rural labor and home industry labor, utilization of marginal land, increasing income, and realizing food security. The economic dimension is the added value and durability of the mocaf.Conclusion: The factors that influence the availability of cassava as raw material for mocaf are harvest growth and an increase in the purchasing price of cassava at the farmer level. Implementation of the development scenario the availability of cassava can be fulfilled.Originality/value (State of the art): Substitution policy for mocaf and cassava harvest growth can increase the availability of cassava and implementation of the development scenario (substitution policy of 30% mocaf and cassava harvest growth of 1%) the availability of cassava can be fulfilled. Keywords: mocaf, model simulation, cassava, supply chain management, dynamic system

Abstract

Batik Tulis Tengah Sawah is one of the UKM in Pacitan and is engaged in hand-written batik. In the production process, the batik maker makes the canting process while sitting on a short chair (dingklik) made of wood without a backrest. The stove used to melt malam is small and there is no table to put the stove on and it is used by 2 batik makers, so it requires the batik makers to sit obliquely facing the gawangan, causing the batik maker to sit with a slight bow. Therefore, it is necessary to assess the risk level of the work posture of the batik when doing the canting process. The purpose of this study is to evaluate the work posture of the batik maker during doing the canting process so that corrective action can be taken to reduce musculoskeletal complaints and bending posture. The result of this research is that the assessment of the risk level of the work posture of batik in all stages of the canting process activity has a REBA score of 5, which is included in the moderate or medium risk level with actions that need to be corrected.
