Macroergonomic Approach for Improving the Municipal Waste Management System in Jakarta

 Abstract—To solve the complex problem of the waste management system in Jakarta, there needs to be a comprehensive approach to the system. One of the approaches that could be used to solve this problem is the macro- ergonomic approach, where Macro Ergonomic Analysis and Design (MEAD) is one of its methods. Through this approach, it is known that the main problem of this system is human error in disposing waste. Improving rubbish bins is a solution that could help the problem technically, where New Product Development Processes (NPD Processes) is implemented to develop the rubbish bin. The new design of rubbish bin has some additional features that would decrease human error in disposing waste. This paper will discuss the color coding, signs of waste segregation, differentiation in locating disposal holes, different types of container lids, types of trash bag hooks, the swing feature of the bin, and the ideal information media of a rubbish bin. I. INTRODUCTION Collecting household disposals and industrial waste is one of the most difficult operational problems faced by local authorities in any large city. This problem is also faced by Jakarta, the capital city of Indonesia. With an increasing number of populations due to the rising number of urbanization every year, Jakartas waste volume is rapidly increasing. The volume of waste generated in Jakarta could reach up to 6500 tons per day. To keep the city clean, the governments Cleaning and Landscaping Agency faced some major waste disposal problems, such as public awareness about cleanness, waste- handling facilities, human resources, legacy, periodic targets, and other problems related to open dumping. A solution is needed to overcome this complex problem. This research is done by redesigning the rubbish bin used in Jakarta, as an effective solution for improving Jakartas waste handling system,

Military Vehicle Dashboard Design Using Semantics Method in Cognitive Ergonomics Framework

Indonesia requires innovation and revitalization for the military vehicles that match the performance of the Indonesian Armed Forces TNI in securing the sovereignty of the Republic of Indonesia. Based on this fact, the need for good vehicle use, effective and efficient is necessary, by the fact the Indonesian military vehicles is commonly old that have limited function and ergonomics. The new vehicle purchased from abroad is also less fit for the soldiers ergonomic profile. The study aimed to design one of the main parts that are considered most representative of a military vehicle to fit between the vehicle function and the profile of soldiers. This study aims to design an instrument Human-Machine Interface in the form of a dashboard with semantic methods and evaluated on a military vehicle with a virtual method in order to maximize the functions of the Human-Machine Interaction in the vehicle in order to improve the performance of the military vehicles that will maximize the ability of the military in using their main combat tools

Visual Usability Design of Financial Personal Assistant Application

One of the personal assistant applications that began to bloom in use is a financial personal assistant application. It is an application that can address financial management issues that are often experienced by young people. Development of financial personal assistant application also needs to be considered in terms of its user interface. To design user interfaces on interactive mobile applications with users, a designer must focus on the user experience to make the app attractive and functioning properly. This research combines Kansei Engineering, Data Mining and Personas approach to develop the affective and emotional design on user interface of the financial personal assistant application.

Crowdfunding website design with lean product process framework

The most dominant problem experienced by sub-sector of creative economy in Indonesia is funding. Crowdfunding is a new way to get funding through internet. Based on observations, almost all of the worlds reward-based crowdfunding is intended for creative industry campaigns, so reward-based crowdfunding is believed to help the development of creative industry in Indonesia. The purpose of this research is to get the design of reward-based crowdfunding website that suits user needs in Indonesia. The Lean Product Process approach, which is the development of Lean Startup, is used to get the appropriate website design. There are six stages in the Lean Product Process framework with different methods in each stage. The methods used in this study were Persona, Kano Model, Product Value Proposition, User Stories, User Experience Design Framework, and Usability Testing. This study conducted two iterations. In the first iteration, website design of clickable mockup was obtained, while in the second iteration web site design of interactive prototype was obtained.

Redesign of commuter line train ticket vending machine with user-centered design approach

The increasing number of commuter line train users was followed by the innovation of ticket vending machine that replaced the manual counter. Problems arise when 79% of users find it difficult to use the ticket machine. The purpose of this research is to produce a prototype of ticket machine that gives ease of use and display. User-centered design approach is used to generate a wireframe, mock-up, and prototype. The respondents involved are 20 people that divided into 2 groups according to their technological proficiency scale. Physical wireframe then arranged into a mock-up in accordance to Indonesian anthropometric measurement. The mock-up then arranged into a 1:1 three-dimensional prototype. The results show a safe and convenient workload on posture evaluation and a high-performance score on the usability testing.

Analysis of technology adoption for real-time aspiration delivery system

City problems occurred had driven government of Jakarta to collaborate with service provider in Indonesia to operate application-based Real-Time Aspiration Delivery System (RTADS) for people to report any issues around Jakarta. However, peoples participation in using this application is much lower than expected by the service provider. This research aims to analyze factors affecting technology adoption of RATDS, so strategies for increasing user of RATDS can be developed. The combination of Unified Theory of Acceptance and Use of Technology (UTAUT) and Task-Technology Fit (TTF) is used to be tested by structural equation modeling (SEM). Results show that performance expectancy, effort expectancy, social influence, and task-technology fit significantly affect user adoption of RATDS. Perceived usefulness and persuasion from others play a big role in user acquisition where they are categorized as early adopters. This indicates the performance of the application must be excellence and influence from other people or leadership must be well felt.

Affective Design with Kansei Mining: An Empirical Study from Automotive Industry in Indonesia

Automotive industry delivers a great contribution to Indonesia by accounting high percentage in gross domestic product. As automotive industry is developing, especially for car industry, the competition between car companies is highly increasing. This condition resulted in a situation where products from different car companies having the same standard for quality. Therefore, customers are triggered to consider another factor beside functional specification and quality, which is affective perception. This research focused on how customers of city car in Indonesia evaluate the product from its exterior shape by considering their affective side. Method of this research is Kansei Engineering, specifically its Kansei Words. Data from customers are processed with the method of association rule mining and conjoint analysis. From the output of this research, there are five groups of Kansei Words that represent customers’ affective perception (i.e., classic and sleek, robust and powerful, sporty and formal, cute, and modern). The final output from this research are five recommended designs for city car exterior shape that describe all the Kansei Words above.

A ground reaction force analysis for designing a sustainable energy-harvesting stairway

There are many issues of how energy is currently generated and consumed. These include the cost of harvesting energy, the ever-growing demand for it, and the ever-decreasing reserve of current most applicable energy resources. Numerous ways to exploit new sustainable potential energy sources have been pursued, one of which is to create an energy-harvester; a device that captures free potential energy, scattered around in its environment, and transform it into another form of energy. Using NPD approach, Puspitarini, Suzianti, and Al Rasyid (2016) has developed a conceptual design of an energy-harvesting device, which includes a selection of product specification options and a gear set layout design.
