Abstract

XYZ Sugar Factory is a sugar factory which has problems related to the effectiveness of the machines at the sugar cane milling station. This can be seen in the condition of machines that are outdated and in 2013 the level of machine downtime at milling stations tended to increase and exceeded the standard percentage set by the company for the last 3 months. Measurement of machine performance at this milling station uses the Overall Equipment Effectiveness (OEE) method, which is then carried out by measuring six big losses to determine the amount of efficiency lost. From the six factors, it can be identified which factor of losses has the biggest contribution in influencing the level of machine effectiveness by using the Pareto diagram. The data used were data from 12 May - 10 November 2014. During that period, the availability value was 94.72%, the performance value was 90.31%, and the quality was 96.78%, so that the OEE value was 82.95%, which means has not met the best practice OEE value, which is at least 85%. The main factors that affect the effectiveness of the machine are idling and minor stoppages losses, namely the machine is idle due to the time waiting for the sugarcane to enter and the problem of machines outside the milling station.

Abstract

The improvement strategy of coffee shop was created by first analyzing the quality of product, service, and pricing of coffee shop to determine the customer requirements using questionnaire. 105 customers of Legend Coffee filled the questionnaire. From 30 attributes, 13 of them needed improvement as their performance rating were below their respective importance, thus resulted in low customer satisfaction. Some product quality and service attributes located in the Concentrate Here quadrant, which requires immediate improvement. Based on those results, then strategic improvements will be made with management using QFD. The highest prioritized improvement strategies are increase in human resources with training in accordance with the job description, increase supervision of each division, and clearer preparation and more detailed SOPs. Improvement strategies then developed based on the voice of the customer with a discussion with management.

Abstract

“Bakpia” is one of food agroindustrial products that use mung bean (Vigna radiata) as raw material. Mung bean peel waste is a source of organic materiali and available in abundance in Yogyakarta. One scenario to improve by-products of bakpia is utilize them as raw material of charcoal briquettes, as alternative energy and due to the decline of petroleum reserves and a dramatic explosion in demand for energy, and liquid smoke for food preservation. This study is conducted to evaluate the critical variables that effect on the production of liquid smoke and charcoal of mung bean peel waste on pyrolysis. This study converted by product of “bakpia” to high value product as liquid smoke and charcoal brequettes. To ensure its quality, pyrolysis process in difference in temperature and the time were conducted. Quality liquid smoke is determined by phenol content, acidity, and the pH value. The production of charcoal, pyrolysis treated in addition based on the temperature and duration of operation, also the weight ratio of the adhesive mixture and pressure. Quality parameters of charcoal briquettes based on physic-chemical properties, namely: water content, ash content, volatile content and calorific value assessed, bound-carbon content, density, and performance of combustion. Besides the technical criteria, financial aspects also be taken into consideration their financial feasibility such as; NPV, IRR, PBP and PI. It was found that charcoal production of mung beans peel waste based on temperature and the duration of the pyrolysis 400 °C for 3 hours, with the results of 7.31 % water content , 22.21 % ash content, 57.03 % volatile compound , and 6696,041 cal/g calorific value. Charcoal Quality obtained at 5 % the amount of adhesive, 50 Kg/m2 pressure of pressing, which 4.93 % of ash content, 14.84 % volatile content, 6188.53 cal/g calorific value, 76.37 % bound carbon content, and has a density of 0.63 g/cm3. The performance of combustion, reached in 6th minute and longer burning flame. The financial feasibility of charcoal briquettes and liquid smoke of mung beans peel waste produce PBP of 1.12 years, NPV of IDR 35,947,702, - IRR of 73.6% and PI of 5.15.

Abstract

Instant chocolate drink is chocolate powder in sachet packaging that has been accompanied by additional ingredients and is easy to consume. Sales competition between products has a determining factor in product selection by consumers and needs to be analyzed on factors that influence consumers to buy. This study aims to find out what are the priority attributes of decisionmaking in willingness to buy instant chocolate drinks. The method used in this research is the Analytical Hierarchy Process (AHP) approach, by arranging the problems hierarchically and then weighting and ranking priorities obtained from the results of distributing questionnaires aided by processing using the Super decision 2.0 application. Based on the results, there are seven (7) subattributes that could be influence consumers in buying an instant chocolate drink: originality taste, affordable prices, product quality, additional flavors, packaging visualization, producers of instant chocolate drink should be able to maintain the originality taste because it becomes the final factor in purchasing decisions. Beside the original taste, producers should be able to maintain affordable prices and not experience an increase in sales prices.

Abstract

Tempeh is one of Indonesian traditional food that have been favored by the locals for centuries. Tempeh has a life cycle from the supply of raw materials, production processes, packaging and transportation that have a potential impact on the environment. In this study Life Cycle Assessment (LCA) is used as a tool to evaluate the environmental impact on Global Warming Potential (GMP). The LCA study will be conducted in tempeh industry “Ibu Sujati” located at Pandean Street, Umbulharjo, Yogyakarta. The LCA study will be focused on the energy consumption in production process, including the raw material transportation . The result showed the boiling process which part of production process has the largest GWP value that equals to 0.488388 kg CO2-eq which contributes 78.79% of the total GWP in the system boundaries.
