This SME produces several handicraft products such as storage baskets with various variants, and furniture. The process of ordering raw materials for SMEs is carried out when there is a demand for incoming products with the order quantity based on the raw material needs in meeting product demand. This study intends to provide recommendations for improving raw material governance to overcome demand fluctuations during the lead time and reduce the total cost of supply chain inventory by implementing an integrated inventory system. To meet the study aim, the EOQ Probabilistic P system (Period Review Method) is utilized. The P inventory model is distinguished into two models namely model P with backorder and model P with lost sales. Next, the Purchase Cost (Ob) and Procurement Costs are applied to the P model. The research method comprises through 3 stages: the pre-field stage, field stage, and the advanced stage (laboratory analysis, data analysis, and reporting). Given the results regarding banana and mendong raw materials supply, it can be observed that for banana raw materials, the reorder time interval that can generate the minimum total inventory cost for banana raw materials is 0.1470 years or 53 days with a total cost of IDR 263,721,081.72. Moreover, it is seen that the suggested model generates the minimum total cost of supply chain inventory compared to the SME policy and the individual model, which justifies the economic feasibility of this model.

One of the competitiveness that supports the development of this sector is a business engaged in the packaging process. Several research studies show that packaging has a major influence on product marketability. However, not all packaging processes are managed by the product manufacturers themselves, but are left to other organizational partners. PBX is one of the organizations engaged in product packaging management. When carrying out the production process, operators experience complaints of musculoskeletal disorders, which have an impact on decreased performance and the risk of injury to operators. This is certainly a bad impact for the PBX. The REBA method is used to carry out analysis and efforts to improve work methods. This method was chosen because this method can help analyze potential injuries based on the operator's body when carrying out a work operation. The results obtained in the initial cond...

However, delivery issues are there all the time. This was experienced by a noodle culinary SME that experienced delays in the delivery of various noodle raw materials and noodle toppings which caused noodle sales activities to be disrupted. In addition, these raw materials have a lifespan (without preservatives) so they must be delivered according to a predetermined schedule and hours. This research will solve this problem by minimizing delays through finding the shortest mileage delivery route. Because each delivery location has its own schedule and time window, the Nearest Neighbor method by paying attention to the time window is used. Based on the calculation results, each distribution route with the shortest distance was obtained, as evidenced by a reduction in the middle route by 0.23 km and the northern route by 5.88 km. In addition, this proposed delivery route was able to save fuel consumption on the middle route by...

The collaboration increases the supply chain’s visibility, which leads to cost efficiency. It may also contribute to enhancing the supply chain’s green performance. This paper presents a supply chain inventory model to guide managers in making optimal inventory decisions considering the logistics cost and carbon emissions. A vendor supplies products under a vendor-managed inventory; hence, it is responsible for the logistics activities. The effect of product deterioration and quality problems are also considered, in which the vendor performs a 100% quality inspection. A carbon price is imposed on total emissions from production and logistics activities under a cap-and-trade regulation. The result is inventory decisions regarding the optimal delivery quantity as well as the delivery frequencies that minimize the total costs. The reduction in t...

They are the most productive terrestrial ecosystems on earth with high priorities for biodiversity conservation. These forests store a substantial amount of carbon in biomass and soil, and they also regulate the transfer of carbon into the atmosphere as carbon dioxide (CO2). Indonesia is having the third tropical forest area in the world after Brazil and Congo. Over 50 years forest has been felled both legally as well as illegally. High rate of forest degradation resulted from unsustainable forest management, rampant illegal logging, forest area encroachment, conversion and natural disaster. All urges rapid improvement of management system of Indonesia’s forest resources (Holmes, 2002). Forest certification is one tool that can support the achievement of sustainable forest management goal. Under current operation of join certification protocol between the Forest Stewardship Council (FSC) and the Indonesian Ecolabelling Institute ...

The problem to solve is to deliver loads to a number of outlets based load requirement. The objective function to minimize is the distance saving and traveling time of the resulted route started from depot to the outlets and return to the original depot. Problem to solve is generating a distribution route in a week considering traffic condition for each day. The original Clarke and Wright saving algorithm is modified such that the resulted routes (from a depot to some outlets) accommodates some constraints such as the maximum allowable traveling time, maximum number of delivery shifts, and maximum number of vehicles. The algorithm is applied to a distributor company with nine outlets, two vehicles, and two delivery shifts. In addition, the traffic condition on the outlet-to-outlet and the depot-to-outlet routes is considered. The simulation of the proposed algorithm sh...

The performance of a supply chain is determined by the human that is involved in the process of planning and operation. Supply chain planning involves activities such as demand forecasting, developing various plans that includes production plan, procurement plan, and distribution plan. Supply chain operations are essentially executing such supply chain processes such as procurement, production, transportation, and warehousing. In all of the above processes, the roles of human are critical, although the specific roles played from one process to another are different. Human performance problems identified in real operational events often involve operators performing actions that are not required for accident response. Analyses of the major failure/accidents during recent decades have concluded that human errors on part of operators, designers or managers have played a major role. On the other hand, the effecti...
