Publisher : APTA and DTIP FTP UGM

Small Medium Enterprises (SMEs) play an important role in the economy of Indonesia. It contributed to the 21.20% of national total economy. Global competition is a challenge and an opportunity for SMEs including agroindustry sector. Therefore, it is needed for strengthening their competitiveness. In the midst of this effort, the raising concern about environment issue has increased. This research aims to determine the alternatives or options in production aspect based on lean and green for small-scale crackers industry. Sustainable Value Stream Mapping (SVSM) was applied to describe the production condition and identify wastes from lean and green point of view. Furthermore, Value Stream Analysis Tools (VALSAT) and Life Cycle Impact Assessment (LCIA) were used to analyze waste throughout the production activity. The results show that the small-scale cracker industry has already implemented synergy of lean and green, however some alternatives for reducing lead time and waste are needed such as demand forecasting and improvement of working methods

Along with prosperity improvement of countries in the tropic, the consumption of wheat-based pro ducts such as breads, cakes, noodles and cookies has increasing tendency in the recent years. Wh eat that is grown usually in the sub-tropic has been investigated intensively for trial cultivation in tropical region. Successful cultivation of wheat in the tropic has been reported but the informatio n on its quality was still very few. This paper reported the quality of wheat grown in the field expe riment at 5 different provinces of Indonesia at an altitude ranged from 1000 up to 1650 meter abo ve sea level. Two samples of wheat from each location were taken and analyzed the physical, che mical, pasting and dough properties. The quality of wheat genotype Dewata was varied dependin g on the planting location. Out of five planting locations, only Jawa Tengah could produce good q uality of wheat. Meanwhile, the wheat from other locations were characterized by weak in pasting and dough properties. Wheat with weak pasting and dough properties could not be used for brea d and noodles’ production. However, they were still suitable to produce cookies and cake

Entering the digital era, shopping activities no longer have to go directly to the seller to get the desired product, including food products such as fast food, beverages, and variou s cooking needs. Currently customers can meet all their needs just simply by accessing a n e-marketplace application developed by the company to order the desired product and t hen the product will be delivered to the courier to the home or where the customer is loca ted. Until 2018 there are at least 10 e-marketplaces in Indonesia that are growing rapidl y and have the most users, of which 6 of them provide food products. The process of deve loping e-marketplace applications has also become interesting to watch as an effort to op timize the marketing of agroindustry products in the digital age. This study wants to find out what attributes on the e-marketplace application platform that affect customers in the decision-making process to choose certain e-marketplace applications. To achieve these goals, the writer uses the Analytical Hierarchy Process (AHP) approach. And the results show that in the decision-making process customers consider 11 attributes contained in t he e-marketplace application platform. Some of them are product search attributes, selle r reputation information, payment methods offered, protection of customer data, and loca tion maps.

This study examines the development of an approach for modeling the response of plant growth to nutrient solution temperature in hydroponic cultivation in a dynamic system. Nutrient solution temperature is one of the essential manipulating factors for plant growth in hydroponic cultivation. Determining the optimal control strategy of nutrient solution temperature during cultivation could lead to maximize the growth of the plant. By identifying the process using a dynamic system, the optimal control strategy can be determined. However, developing a dynamic model of plant growth to nutrient solution temperature is not easy due to physiological behavior between them are quite complex and uncertain. We propose the long short-term memory (LSTM) networks to identify and develop a model of dynamic characteristics of plant growth as affected by the nutrient solution temperature. Chili pepper plants were used to obtain time-series data of plant growth, with five different types of dynamic nutrient solution temperature patterns for system identification. The results showed that the proposed LSTM model provides promising performance in predicting the response of plant growth to nutrient solution temperature in hydroponic cultivation.

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.
