Improving Green Supply Chain Management in Furniture Industry Through Internet Based Geographical Information System for Connecting the Producer of Wood Waste with Buyer

Although there were stated in theory, in practice, there are some factors that limiting the recycling practices in the furniture industry. These include the geographical location of the waste resources which is restricting the integration of the companies that generate the waste and those that ultimately use it. Based on this condition, the purpose of this study is to develop the application internet based Geographical Information Systems (or internet GIS) as a decision support system in analyzing geospatial data for wood waste collection and transportation in the furniture industry. This application is aimed at encouraging the implementation of green supply chain management (GSCM) practice in the furniture industry through making the process of collecting and transporting the wood waste for recycling process easier. This study has used Software Development Life Cycle (SDLC) process as a tool for designing the proposed application of internet GIS. There were several Small and Medium Enterprises (SMEs) in the furniture industry and collector of wood waste in Jepara and Surakarta district attached in the proposed application as a preliminary of object for the application. This study resulted that, as a decision support system, the implementation of internet of GIS by the SMEs in the furniture industry and collector of wood waste allowing them to describe the geographical location of each party and then, based on the certain criteria, the system will rank the recommended SMEs as the producer of wood waste based on the minimum cost of collecting and transporting the wood waste from each of SMEs.

Vehicle routing problem modelling to minimize a number of vehicle by considering heterogenous fleet vehicle

This paper presents the development of a model of Vehicle Routing Problem (VRP) with heterogenous vehicle fleet size and mix vehicle routing (HFSMVR). The solution is built using a heuristic approach, namely sequential insertion and 1-0 relocation improvement. The model considers aspects of multiple trips, multiple products and compartments, split delivery, and multiple time windows. The model is applied to solve the problem of fuel oil distribution in Nusa Tenggara Timur (NTT). Based on the model of VRP HFSMVR, tankers with capacity of 2.000 kilolitres and 4,700 kilolitres are the solution for the distribution problem that gives minimum of tour quantity, total time of completion, and range of completion time. The results of this study shows that in the case of heterogenous fleet size, selected tankers were varied and not necessarily the ones with largest capacity.

Analysis of frontal protection system on a car

Pedestrian accidents caused by car in Indonesia is quite high. Pedestrian injuries during a collision between a car and a pedestrian can be fatal. In Indonesia, the old cars is still used because there are no regulations which restrict the using of a car based on the production year of vehicles. The old cars do not have some features to protect the pedestrians in the condition of a collision between a car and the pedestrian. The objectives of this study is to determine the effect which occur in the conditions of a collision between a car and a pedestrian by creating a direct collision simulation using a dummy as a form of artificial pedestrians and MPV car as a case study. Direct collision simulation process resulted in injury points on dummy. The injury rate was obtained by the area damaged from direct collision simulation process by calculating the surface area of injury on dummy. The design of the proposed pedestrian protection was to minimize of pedestrian injury suffered by using FAST. The outlining descriptions of the functions on the front part of the car were obtained by brainstorming. The additional function for pedestrian protection that previously did not exist at the front of the car was proposed in the form of Additional Frontal Protection System, e.g. with a height below the average human knee (496 cm) and a material which could absorb the impact was recommended. By applying the Frontal Protection System, the function of the front part of the car will increase so that the value of the car itself will increase consequently.

Usability Evaluation of Anthropomorphic Prosthetic Hand Based on ISO 9241-11

This paper aims at evaluating an anthropomorphic prosthetic hand based on usability concept. It can be controlled for pre-defined five motions. The assessment is conducted by design approach. Users are given the task according to the rules of hand benchmarking in Southampton Hand Assessment Procedure (SHAP) by using Anthropomorphic Prosthetic Hand to perform daily activities. The quantitative data is obtained by a test that based on the criteria of learnability, memorability, satisfaction, efficiency and errors. The qualitative data is obtained by giving USE (Usefulness, Satisfaction and Ease of Use) questionnaires. The recommendation design is prepared by using Quality Function Deployment (QFD) method to combine suggestions from respondents and product developers. Assessment by USE questionnaires shows that the usability level of Anthropomorphic Prosthetic Hand on the aspect of usefulness is 68.3% and 63.8%; satisfaction is 59.5% and 55.6%. The improvement recommendations based on the result of (QFD) are Variant material to connect to the arm, System to connect to arm, Dimension of connecting to arm, Connection information to the arm, and Instructions for the exercise stage. So that improvement is done in accordance with ISO 9241-11: 1998.

The analysis of market knowledge competence effect and research & development (R&D) toward the policy making of new product development

The increasing mobility of people without adequate provision of mass transportation infrastructures makes people choose private transportation like motorcycles. Such circumstances lead the motorcycle manufacturers in Indonesia competing to develop their products to meet the needs of customers. In addition, the new regulation of Central Bank of Indonesia dealing with the credit advances has raised the intense competition of motorcycles industries in Indonesia. One of the ways to win the competition is by developing new and improved products. In developing and improving the products, companies need to consider resource utilization. In this research, researcher utilizes the resources that exist both inside and outside the enterprise such as customer demands, intensity of competition, perception of the importance of market knowledge, importance of market competence, and internal R&D as well as external R&D is expected to develop new products that are superior. The study involved 150 employees as respondents. ...

Effect of speedometer positioning: Distraction and workload while driving

One of the automotive design car developments is speedometer position change. There are two speedometer positions used by the public, i.e. in behind the steer and on the center of dashboard. Speedometer position affects the visual scanning time information on the speedometer (glance). Total Time glances are very influential to distraction and workload while driving. The purpose of this study is to determine the position of the speedometer that minimizes distraction and workload while driving. The type of this research is a real experimental study using real cars on the road. The number of respondents involved was 12 peoples. Distraction data were obtained from the total glances while driving (using cameras). While the workload while driving was obtained from a questionnaire adapted from DALI (Driving Load Activity Index). Based on the analysis of total glances and questionnaires, speedometer on the center of dashboard showed a higher total glances and higher average value of global demand attention, visual demand, as well as stress. Consequently, in order to maintain safety and comfort in driving, the speedometer position in behind the steer is better than on the center of dashboard.

Model simulations of noise pollution due to departures and approaches of passenger aircrafts around Achmad Yani airport Semarang — Indonesia

AchmadYani Airport in Semarang city, Indonesia, is an airport operated by PT AngkasaPura1 which can service 3.2 million passengers annually in 2013. Unfortunately, air transportation can cause numerous environmental damages with serious consequences on population health, such as noise. Noise control of an airport operation can be evaluated its effectiveness through noise contour. As a first step to evaluate the noise control, the objective of this study is to develop a noise contour around AchmadYani Airport by using INM (Integrated Noise Model) and to measure the area of each category based on the Government Ordinance No. 40/2012. In this research, the simulation was conducted on Saturday schedule when the lowest number of aircraft operations was scheduled (44 departures and 44 approaches). According to this study, the area category level I, II, and III using WECPNL (Weighted Equivalent Perceived Noise Level)are 6.774 km2; 2.701 km2; and 1.32 km2, respectively. There are a hospital and six schools located in the area categoryI. Further study is needed to identify possible noise control at AchmadYani Airport.
