Abstract

In Indonesia, it is a common practice for people in the urban area to bring children when riding a motorcycle. This habit raises a safety issue for the children as well as the motorcycle rider. For this reason, an additional child seat that allows the child to sit safely is demanded. This study aims to produce an innovative design of an additional child seat for a motorcycle that is portable, safe, durable, easy to use, and comfortable. The seat is designed so that it can be installed at the front and back sides of the rider in the motorcycle. The proposed model is designed to have a mass of between 0.6 to 3 kilograms. It is equipped with a seatbelt and head-protection pad. To evaluate the structural strength, theoretical analyses of solid mechanics were performed under static and fatigue loading conditions. As a result, the static safety factor of the child seat design for the front position was found to be 3.67. On the other hand, the fatigue safety factor of the child seat design for the front position was found to be 2.26, which is considered an infinite life. For the back position, the fatigue safety factor was found to be 2.36. The proposed design is expected to give a contribution to the development of innovative devices in transportation technology.

Abstract

Currently, the transportation sectors are heading into the advancement of sustainable transportation technology to tackle the issue of unsustainable transportation system which leads to various drawbacks in the future. One of the innovation in sustainable transportation technology is the development of electric vehicle (EV). However, there are noticeable difference between sustainable transportation system and conventional transportation system that requires a massive and synchronous network of related stakeholders to keep innovating and catch up with the progression. On the other side, transportation sector is one of the sector with the massive development that has the consequences of high risk and uncertainty, which leads to the tendency of innovation avoidance. Therefore, the innovation network of EV needs to be nurtured to ensure its sustainability. From the previous study on various sectors, the innovation strategy focuses on two matters: innovation target and actor integration. The latter purpose is required to be conducted in an inclusive manner by engaging people from inside or outside the organization. In the case of innovation in sustainable transportation, the vertical approach plays a significant role in terms of fostering technological advancement. The main solution to reach this objective is through the well-established research ecosystem, which significantly supported by R&D investment by the government. The government takes the role of the innovation strategy implementer to establish a strong research network. Besides as the R&D funder and the hub between researcher and industry, the government also take a role to keep the dynamics of an ecosystem through interaction stimulation, while also engage the innovation results to be relevant with the social, technological, environmental, and economic problems. Moreover, the research center also takes an important role in the ecosystem, such as to engage reiteratively with the industry, become the open-innovation enabler, have the dedicated research agenda, become the multidisciplinary innovation enabler, collaborate with multi-stakeholders, has core research infrastructure, and become the innovation cultural hub. While the country’s industrialization demand keep rising, the research center could consistently become the intermediaries in conducting the research and build the relationship with other non-industry actor. This way, the high risk and uncertainty of innovation could be reduced.

Abstract

Fleece has strong and good fiber characteristics, which are needed to manufacture brake pads. This study aims to analyze the fleece performance as a friction component material in brake pads. The fleece was initially pre-treated by heating for 4 hours at 150°C and cut into 2 mm sizes. The epoxy resin and hardener were mixed with a ratio of 1:1. The 0.5 g pre-treatment fleece was added to the resin mixture, so the total mass of the resin-fleece mixture was 12.5 g. The mixture was then molded into a cube mold (dimensions of 2.5 × 2.5 × 2.5 cm). The brake pad was dried at room temperature for a day. The characterizations were done using the compressive strength and puncture strength test. The results showed that the fleece brake pad has good mechanical characteristics, demonstrated by the pressure of 215 MPa, which can still be held by the surface of the fleece brake pad. The puncture test showed an average puncture of 76.43%. Overall, the fleece shows good performance on the brake pads. Fleece has many minerals that make it as powerful fiber characteristics and prospective as a friction component material on the brake pads. This research is expected to provide new information about organic materials for friction materials in brake pads.

Abstract

This study examined the effect of sustainable infrastructure and service delivery on sustainable tourism in Kashmir Valley through the five main destinations by covering essential stakeholders. At present, tourism potential nations face destination sustainability issues in various junctures of the tourism sector. Therefore, international agencies and nations focus on sustainable tourism through sustainable transport infrastructure, other factors and improved service delivery. Few studies underlined the role of sustainable infrastructure in service quality and their collective impact on sustainability without empirical evidence at the destination level. At this juncture, the current study presents the summaries of empirical investigation of the effect of sustainable transport infrastructure and services delivery on sustainable tourism in Kashmir Valley. For analysis, the Kruskal-Wallis test (non-parametric) is applied to assess the variation in sustainable tourism based upon the performance of sustainable infrastructure and service delivery at destinations. The application of the Kruskal-Wallis independent samples tests duly confirmed the significant results. Sustainable tourism differs by transport infrastructure performance, other elements and service quality of the destinations. Therefore, it is to be stated that poor functioning of transport infrastructure and other basic structures adversely affects service delivery and raises sustainability issues at destinations. It asserts that the comprehensive sustainable transport infrastructure, water supply and drainage, health and sanitation, solid and liquid waste management are highly required to combat environmental issues and ensure sustainability at destinations. The findings of the study have significant policy implications to promote green infrastructure, quality services and development of sustainable tourism at destinations.
