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.

Environmental impact analysis of batik natural dyes using life cycle assessment

The use of natural dyes for batik dyeing is fewer than synthetic dyes because of its limitations in the application such complexity in manufacture and usage. For ease of use, natural dyes need to be processed into instant products. Extract of natural dyes are generally produced in liquid form that are less practical in long-term use. Dye powder obtained by drying the liquid extract using spray dryer. Production process of liquid natural dye is simpler and require less energy but need more energy for transporting. It is important to know which type of natural dyes should be produced based on their environmental impact. This research aim to compare environmental impact between liquid and powder natural dyes and also to find relative contribution of different stage in life cycle to total environmental impact. The appropriate method to analyze and compare the environmental impacts of powder and liquid natural dyes is Life Cycle Assessment (LCA). The “cradle to grave” approach used to assess environmental impact of powder and liquid natural dyes of Jalawe rind throughout production process of natural dyes, distribution and use of natural dyes for coloring batik. Results of this research show that powder natural dyes has lower environmental impacts than liquid natural dyes. It was found that distribution, mordanting and packaging of liquid dyes have big contribution to environmental impact.The use of natural dyes for batik dyeing is fewer than synthetic dyes because of its limitations in the application such complexity in manufacture and usage.

Risk analysis using AS/NZS 4360:2004, Bow-Tie diagram and ALARP on construction projects of Banyumanik Hospital

The Determination of risk is an uncertain event. Risks can have negative or positive impacts on project objectives. A project was defined as a series of activities and tasks that have a purpose, specifications, and limits of cost. Banyumanik Hospital Development Project is one of the construction projects in Semarang which have experienced some problems. The first problem is project delays on building stake. The second problem is delay of material supply. Finally, the problem that occurs is less management attention to health safety as evidenced by the unavailability of PPE for the workers. These problems will pose a risk to be a very important risk management performed by contractors at the Banyumanik Hospital Development Project to reduce the impact that would be caused by the risk borne by the provider of construction services. This research aim to risk identification, risk assessment and risk mitigation. Project risk management begins with the identification of risks based on the project life cycle. T...

Analysis of the community website usability using Koohang's model based on task performance comparison result

Kaskus.co.id is one of the biggest community site which ranks 1st in Indonesia and 257 positions for the world in 2010. As time went on, many other similar sites with kaskus.co.id that is able to meet the needs of Indonesian social-networking communities such as forum.detik.com. This gives the impact of a decline in the number of access to the site kaskus.co.id and shift its rank. The results of the interview against the user community site kaskus.co.id is there are some shortcomings on the site, i.e. the process of posting the increasingly complicated, too many ads that cover the main content, and the difficulty of organizing pictures. The purpose of the research is to determine the value of usability of the community site kaskus.co.id as Indonesias largest sites which ranks 1st in Indonesia in 2010. There are 22 indicators divided into 3 indicators for task performance and 19 indicators Koohang model. Task performance is used to find out the level of site performance directly while the indicator of Koohans models used for qualitative questionnaire assessment. The determination of the value of usability of the site kaskus.co.id obtained using WEBUSE with merit conversion scale. The whole valuation WEBUSE respondents will be processed to earn points for each questionnaire indicators and the level usability of the community site kaskus.co.id. The results of this study in the form of value of usability of the sites, the analysis of the 19 indicators that affect the value of usability and indicators guide the creation of community sites. In this kaskus.co.id case, we obtained information that kaskus.co.id has a moderate level of usability.
