Abstract

UKM Roti H-34 is one of the Small and Medium Enterprises (UKM) in Samarinda City which is engaged in the culinary field that produces unyil bread. The superior product has decreased in sales. Based on this, this study aims to determine the best alternative marketing strategy solutions to increase sales volume and competitiveness based on internal and external factors that affect the company. Marketing strategy analysis is carried out in several stages, the first is using the IFE and EFE matrices. The results obtained on the IFE matrix is 3.779, while the EFE matrix is 2.905. The second stage is the matching stage using the BCG matrix, benchmarking, IE matrix and SWOT matrix. In the BCG matrix, the results show that the market growth rate of -37% of the market share of each competing company is 0.22, 0.23, and 0.25, which indicates that the company is in the dog quadrant. In the IE matrix, it is found that UKM Roti H-34 is in cell IV, a strategy that can be used, namely growth and build. Then formulated a strategy using the SWOT matrix and obtained nine alternative strategies. The final stage is the decision stage to use QSPM for the selection of strategies that can be implemented by UKM Roti H-34. The alternative strategy that is most appropriate to be applied is to use the internet media to carry out online promotions in order to increase sales and the number of consumers with a TAS of 5.447.

Abstract

TPM is an innovative approach to maintenance activities that focus on preventing damage to machines / equipment and preventing the occurrence of defective products related to machines / equipment. The success of implementing TPM can be measured from the Overall Equipment Effectiveness (OEE) value. OEE measures how effectively equipment is used and functions to keep equipment in ideal condition by minimizing six big losses. OEE consists of three main, measurable components: Availability, Performance and Quality. In this study, OEE calculations were carried out on Molding machines at PT. CWI. The results of OEE calculations for the period July 2019 to June 2020 ranged from 45.49% to 74.35%, indicating that the world class benchmark standard (85.0%) has not been achieved. Based on the loss analysis, it was identified that the dominant losses were Idling at 42.2%, Rework at 17.7% and Breakdowns at 17.3%. The three losses have the potential and become the main priority for improvement in the context of increasing OEE.

Abstract

UD.Ridwan is one of the community businesses in West Aceh, precisely in Ujong Kalak, which processes fish waste into animal feed. UD.Ridwan in its business activities has experienced several problems in the part of the supply of raw materials that are not fixed, because the amount of fish waste is not fixed per day. UD. RIDWAN in its production activities, every 1 kg of raw materials used can produce 761 grams of feed product. As a result, the results of feed production are also not fixed, and cannot fulfill orders from consumers, so there is often a mismatch between demand and orders. This will lead to unfulfilled consumer demand and delays in distribution to each distribution center (DC). UD. Ridwan distributes his products to existing DCs, namely: Medan, Banda Aceh, and Lhokseumawe. To fix the losses faced by the company, it is necessary to measure the performance of the supply chain first. There are several models of supply chain performance measurement systems, namely: POA (Performance of Activity) and SCOR (Supply Chain Operation Reference). POA is a model used to measure the performance of activities that are part of the process in the supply chain. Activity performance is measured in various dimensions, namely: costs, time, capacity, capabilities, productivity, utilization and outcomes. Meanwhile, SCOR is basically a model based on a process

Abstract

XYZ Inc. is one of manufacturing companies that produce eco friendly polymer/resin. Five production machines were used to do some production process such as mixing and extracting. Production machine number three often suffered trouble that caused production stop. the purpose of this research is to calculate performace of production machine number three using Overall Equipment Effectiveness (OEE) and analyze the elements that caused failure of production machine number three using Failure Mode and Effect Analysis (FMEA). The data that used in this research was January to December 2019. The result showed that average OEE value is 70,49%, the highest RPN value is 448 on heating process and critical component of production machine number three was heater.

Abstract

PT Frisian Flag Indonesia is a manufacturing company in Jakarta which is engaged in the milk processing industry. PT Frisian Flag Indonesia has not implemented a detailed performance measurement system and only applies a measure of the effectiveness of company performance. The need for Supply chain performance measurement to be able to find out the results of the Supply chain performance of sweetened condensed milk and make improvements to activities that are not optimal. The method used in this research is the AHP-SCOR method and to determine the Supply chain performance score, the Key Performance Indicator (KPI) measurement is used. The results showed 27 valid KPIs using the Snorm De Boer normalization process and the values obtained were: plan was 88,83, make was 93,79, source was 84,545, delivery was 88,149, Return was 38,53. The results of the SCOR model are 81.45. The need for improvements that prioritize performance with the smallest value, namely return.

Abstract

The right production design at a company will get effectiveness and more production efficiency, including the plan for material requirements or raw materials used by the company. In essence, planning to meet the needs of the material in a company is expected to produce an appropriate system to be applied, therefore making the production process smooth. Where this research aims to compile Material Requirement Planning (MRP) with lot-sizing technique, then compare the results to obtain the optimal combination of raw material procurement. The use of time series method on-demand uses past data, namely the last two years and the forecasting results use the additive decomposition method because this method gets a minimum error value. By using POM, the demand prediction for one year is 6951 scores. Meanwhile, the MPS results on the raw material for one year of songkok required 488 pcs of velvet cloth, 1391 kg of pelisir and 6951 scores of bos-bosan.  From the MRP results, the PPB technique is the most optimal for planning the raw material needs of velvet, lining and boredom by ordering the purchase of natural velvet fabric as much as six times, pelisir 1 time and bos-bosan as 6 times.

Abstract

Wastewater is one of the byproducts produced by coal mining companies. The wastewater contains suspended particles as well as heavy metals. Various attempts have been made to treat wastewater before it is discharged into the environment. This is done so that the waste water does not damage the environment. One way to do this is to settle suspended particles in wastewater or what is known as TSS (Total Suspended solite) using the coagulation-flocculation method. The coagulant used in this study is alum Al2 (SO4) 3. This research was conducted to determine the optimum dose or level of addition of alum into wastewater. The addition of alum is carried out in different doses, this is adjusted to the volume and discharge of waste water that is flowed to the WMP (Water Monitoring Point). The optimum dose of adding or using alum Al2 (SO4) 3 into WPM is 0.03 g / L for WMP 11, and 0.05 g/L for WMP 13.
