Abstract

Waste are commonly generated during the utilization of raw materials. Therefore, they are become important to consider lean manufacturing to achieve the overall business objectives. PT XYZ is a major company in processing pine resin and its derivatives, including gum rosin, turpentine and rosin ester, mainly used as featured commodities. During production, a certain amount of unwanted materials in the form of defect and in the form of work-in-process (WIP) that caused waiting wastes are obtained, particularly at the rosin ester floor. This study aims to identify the waste types and their dominant factors that caused waste occurred in PT XYZ, as well as recommend improvement strategies in boosting production efficiency. Based on the identification results, two dominant wastes occurred in the form of defects and waiting. The defect and scrap portions were prevalent in gum rosin drops, flakes, brushed dust and products that did not fulfill color and size specifications at 63.72 kg/shift that equal to 2,08% scrap rate per shift. Meanwhile, waiting waste refers to work-in-process (WIP) on Oleo Pine Resin (OPR) storage and delay interval for a complete sampling process. The WIP circumstance was also observed at the packaging workstation. Furthermore, repairing tank leaks, allocating special workers to flaking workstations, extending workers’ supervision, combining flake cooling and transportation processes, procuring cooling conveyors and increasing the quantity of esterification reactors were recommendations for optimum production. These proposed activities have the capacity to enhance the process cycle efficiency (PCE) value from 4.65 to 6.34%.

Abstract

There are five types of cotton waste produced by the Spinning Division of PT. Sri Rejeki Isman Tbk: dropping, flat strip recyclean, flat strip c, air waste, and fan open end, which has a smaller trash content. The research objective is to determine the potential utilization of cotton waste as the basic material for white oyster mushroom planting media, to determine effect of planting media formula on the growth of white oyster mushroom, and to determine the best formula for white oyster mushroom planting media. Utilization of cotton waste are examined by 5 formulas: control with 100% sengon wood powder + 200 gram bran + 10 gram lime (S0), 50% dropping + 50% sengon wood powder + 200 gram bran + 10 gram lime (S1a), 75% dropping + 25% sengon wood powder + 200 gram bran + 10 gram lime (S1b), 50% fan open end + 50% sengon wood powder + 200 gram bran + 10 gram lime (S2a) and 75% fan open end + 25% sengon wood powder + 200 gram bran + 10 gram lime (S2b). This study uses a 5x3 Completely Randomized Design (CRD 5x3) and is then analyzed using the One Way Anova test and the Least Significant Difference (LSD) test. The best formula was chosen for planting media based on the highest score in Zero-One Integer Programming. Parameters observed on the planting media are changes in the content of cellulose and lignin, while on the fungal growth is the form of mycelium fulfillment time; the number of fruit bodies; hood width; wet weight, and stem length. This study indicates that cotton waste can be used as a base material for white oyster mushroom planting media, where the best formula is S2b. During fungal growth, in the planting media with formula S2b, cellulose degradation occurs from 66.7% to 60.8%, and lignin degradation occurs from 10.5% to 6.6%. In addition to the media, formula S2b produces mushrooms with growth characteristics including mycelium fulfillment time of 28.33±1.53 days, the number of fruit bodies 17.67±8.96, hood width 5.76±0.87 cm, wet weight 143.33±26.27 grams, and stalk length 4.52±0.55 cm.

Abstract

Coffee consumption in Indonesia has increased significantly with the increase in coffee shops. According to data obtained from the data books in 2020, coffee consumption has increased by nearly 400,000 tons. The increasing number of coffee shops in Indonesia, particularly the Sleman Regency is due to the pandemic and changes in consumer behavior. Therefore, the purpose of this research was to determine the impact of consumer behavior on the purchasing decisions at Coffee Shops based on the personal, social, psychological, and cultural factors as well as the marketing mix and its improvement during the pandemic. In this research, 10 local coffee shops in the Sleman regency were used and consumers between the ages of 17 and 27 years who had purchased coffee drink products and made transactions in the past six months were selected. The respondents comprised 157 people, and the analysis was carried out using two methods: Partial Least Square Structural Equation Modelling (PLS-SEM) and Importance Performance Analysis (IPA). PLS-SEM was used to analyze the relationship between consumer behavior factors and purchasing decisions while the IPA method was used to analyze the most effective marketing mix during the pandemic. According to the result, the factors that influence the decision to purchase coffee are the psychological factors and marketing mix while personal, cultural, and social factors had no significant effect on the coffee purchasing decisions during the pandemic. Consequently, the marketing mix that needs to be focused on is price adjustment on the drink purchased.

Abstract

Companies need an Occupational Safety and Health (OSH) culture based on a new life guidance during the Covid-19 pandemic. The application of OSH at So Good Food Dairy Company is moderate, though there are no control measures to minimize this risk. This study further aimed to analyze the application of OSH in the workplace and determine the implementation of the OSH Management System (OSHMS). Furthermore, it focused on identifying the probability of accidents at each workstation and proposed risk mitigation plans and anticipatory steps. Questionnaires were then administered to collect primary data from 62 respondents at the So Good Food Dairy Company’s processing, filling, packing, and storage workstations. Similarly, secondary data were obtained from documented information about the company’s OSH. All the respondents provided valid answers with a Cronbach alpha value of 0.9671, considered very reliable. Moreover, the questionnaire responses showed that So Good Food Dairy Company was rated highly by workers. Failure Mode and Effects Analysis (FMEA) was used to identify the factors causing work accidents and Risk Priority Number (RPN), while recommendations for improvement were made based on the Hazard Identification Risk Assessment & Risk Control (HIRARC) principles. A total of 12 probability accidents were observed in processing, four in filling and packing, and six in storage. Therefore, this study proposes an OSH design that includes an OSHMS planning based on clauses ISO 45001:2018 and ISO/PAS 45005:2020. Additionally, seven OSH programs and a risk mitigation road map using the Pareto Chart principle to set priorities were recommended.

Abstract

The natural ripening of ambon kuning, a typical banana widely consumed in Indonesia, tends to produce a non-uniform yellowish peel color of the fruits. Some degreening techniques using calcium carbide or ethepon, although improving the peel color appearance, may pose a safety risk compared to ethylene degreening, a technique using ethylene gas, a gas naturally produced by the fruit. This study aimed to determine the effect of ethylene degreening on changes in peel color, physical quality, and chemical content of ambon kuning and determine the combination of treatment that produces the best results. Taguchi design, with two levels for each of the three treatment factors (ethylene gas concentrations of 185.2 and 277.8 ppm, storage temperatures of 16±1 and 29±1 °C, and gas exposure time of 48 and 72 hours) was applied to banana samples stored in a hermetic bag in a temperature-controlled container. Grey Relational Analysis (GRA) was applied to get the best results considering multiple performance measures: peel color (measured as lightness L*-, green -a*-, and yellow b*-values), hardness of peel and pulp, total dissolved solids, total chlorophyll, and total carotenoids contents. The best results were obtained when degreening was carried out with a gas concentration of 185.2 ppm at a storage temperature of 16±1 °C for 48 hours.
