Abstract

Increasing plastic waste in Indonesia make residents around Brontokusuman Waste Bank RW 20-22 Yogyakarta produce ecobrick.  Ecobrick is one way of handling plastic waste by packing clean and dry plastic into a plastic bottle to specified density.  The problem nowadays is nostandard operating procedure (SOP) for the ecobrick production.  Therefore, this study aims to develop SOP for ecobrick production to be systematic and structured so as to maintain product quality and consistency both in terms of aesthetics and product weight.  This research was conducted using qualitative methods, like observation, interviews with actors and SOP experts, and documentation.  Then, data analysis method by Miles and Huberman was carried out, such as reduction, evaluation and conclusion.  This research also presents preparation of initial SOP design, simulation of initial SOP production and problem identification, then improvement, final SOP design and simulation.  The result is SOP production of standardized aesthetic and weightecobrick.

Abstract

Work posture analysis plays an important role in providing safe and productive workplace, through minimizing musculoskeletal symptoms or disorders. The postural analysis can be conducted through observation, direct, and self-report method. Each has their advantages and disadvantages. Purpose of this study is to compare obervation and self-report analysis in the context of degre of agreenes. One rater observes and gives rating to the fifteeen work postures in an automotive service company using Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment (RULA). In addition, six workers in the automotive service company also fill out the Nordic questionnaire as a self-report of musculoskeletal symptoms or disorders. Descriptive analysis is conducted to compare the musculoskeletal symptoms using both observer and self-report analysis. Results show that RULA is slighlty better than REBA in accordance to the Nordic questionnaire’ result. Implications of the result is discussed.

Abstract

Shrimp agro-industry is one of the food processing industries, which converts raw shrimp into high-value shrimp processed products. The production system used in shrimp agroindustry to respond market demand is a hybrid make to stock (MTS) and make to order (MTO). The decision to determine which products will be stored as supply sources and which products are made to fulfill orders is a critical decision that must be made on the MTS-MTO hybrid system. The concept of customer order decoupling point (CODP) is used to identify material flow points that connect a product with different consumers. This study aims to present a conceptual model in the MTS-MTO hibrid system based on customer order decoupling point (CODP) which is adjusted to product characteristics, production characteristics and market characteristics in the shrimp agroindustry. The results of the study are presented in a business process model template that describes the order of decisions for storing products or making products to fulfill orders and conceptual models in the form of diagrams named the CODP conceptual model on shrimp agroindustry.

Abstract

Value added is an indicator of the economic strength of a business. There are several ways to increase added value, namely by processing into new products, preserving, making attractive packaging, and improving the quality of a product. Most of the yield of purple cassava in the Karangnyar area is still sold in the form of raw products and has not been much processed, so the added value is still low. This study identified various processed cassava products, analyzed the added value of processed products, analyzed the added value of purple cassava supply chain and proposed the development of purple cassava. The method used to calculate the added value is the Hayami method. The results of the study showed that there were three alternatives of processed products of purple color namely bakpia, thymus and wingko. The biggest added value of processed products is wingko with an added value of Rp. 26,561 and a ratio of 64%. The highest value supply chain added is UMKM Murakabi network with an added value of Rp. 19,152 and a ratio of 70%, while the network with added value the lowest is a retailer network with an added value of Rp 6,257 and a ratio of 28%. These results indicate that the development of purple cassava business should be done by processing purple cassava in the form of wingko.

Abstract

Pallet Industries have an important role in supporting the smooth supply chain activities. Research on risk control in the pallet industry's inbound logistics is still not widely implemented. The risk caused by activities and process of raw materials procurement in the wood pallet industry is a crucial problem that must be immediately assisted to find a model solution. This study presents a new model in risk management by applying a socio-technical system approach to identifying, evaluating, and determining risk control strategies. A case study on an wood pallet industry in East Java was presented to validate the risk management model. Results of the risk assessment show that the highest risk was loss of raw material (R23). This risk was included in the safety perspective, so transferring risk to an insurance company was recommended to mitigate the risk. The results of this study were expected to help the pallet industry in minimizing losses due to risks in the inbound logistic process.

Abstract

CV Valasindo is furniture industry that produces a wide range of wood product.The production process in CV. Valasindo is devided in two areas, preparation of materials area and production area. This research is focused on work posture of the production area’s workers. The production area itself consists of work stations such as assembly, construction and finishing. The production area  was chosen because on the production process in this area is still done manually by the operator. Additionally, on the production area is also still present a series of no ergonomic work posture, both on the work station construction, assembly and finishing. The purpose of this research is to identify a work posture on the production area and doing an improvement to lowers the risk of musculoskeletal injuries. Based on the results of the assessment work posture against 18 work stations at the production area, the seat assembly work station it is known that has the highest risk of musculoskeletal injuries with a score of REBA 9, OWAS 3 as well as score NBM 75. Based on work by posture assessment method of QEC, REBA, OWAS and reinforced with method NBM then the improvement will be focused on work station assembly seat. In this study, the improvements done by designing a working facility in the form of tables and chairs work. Based on the results of the design work facilities have been simulated and the result is the risk of musculoskeletal injuries that used to be high risk decrease to be low
