Enablers and Barriers for the Transformation of Manufacturing After the COVID-19 Global Crisis

It is obvious that COVID-19, which is one of the main agenda items of humanity, has an effect on global production facilities. It has been tried to create a roadmap for producers to overcome existing and similar crises with proactive solutions. The reflections of the global crisis on production are carefully examined in the study. The epidemic is not limited to a single country, but affects all parts of the world, leaving supply chains and manufacturers in a difficult situation. Just as the concept of the new normal for consumers has come to the fore, the necessity of adapting to the new norm by implementing certain technologies that have been emphasized in recent years is now more clearly felt for manufacturers. The pandemic process experienced and the difficulties and enablers that producers face/will face afterwards are explained in detail under the headings of human resource management, flexibility, sourcing, technology level, logistics.

The Mathematical Models of the Operation Process for Critical Production Facilities Using Advanced Technologies

The paper presents data on the problems of monitoring and diagnosing the technical conditions of critical production facilities, such as torpedo ladle cars, steel ladles. The accidents with critical production facilities, such as torpedo ladle cars, lead to losses and different types of damages in the metallurgical industry. The paper substantiates the need for a mathematical study of the operation process of the noted critical production facilities. A Markovian graph has been built that describes the states of torpedo ladle cars during their operation. A mathematical model is presented that allows determining the optimal frequency of diagnostics of torpedo ladle cars, which, in contrast to the existing approaches, take into account the procedures for preventive diagnostics of torpedo ladle cars, without taking them out of service. Dependence of the utilization coefficient on the period of diagnostics of PM350t torpedo ladle cars was developed. The results (of determining the optimal period of diagnostics for PM350t torpedo ladle cars) are demonstrated. The system for automated monitoring and diagnosing the technical conditions of torpedo ladle cars, without taking them out of service, has been developed and described.

ROLE OF FARMERS GROUPS IN INCREASING SUSTAINABLE RICE PADDY FARMING BUSINESS IN LUBUK BAYAS VILLAGE OF PERBAUNGAN SUBDISTRICT

Farmer groups as a forum for organization and collaboration between members have a very important role in the life of the farming community, because all activities and problems in farming are carried out by groups simultaneously. With the existence of farmer groups, farmers can jointly solve problems which include the fulfillment of agricultural production facilities, technical production and marketing of products. Seeing this potential, farmer groups need to be fostered and empowered further in order to develop optimally. In increasing rice production, it is necessary to preserve the production environment, one of which is through the use of organic fertilizers. Various forms and materials of organic fertilizer can be applied depending on the availability at the farm location. In an effort to improve sustainable farming, The things that are applied are increasing productivity in farming activities and the use of superior seeds, the use of fertilizers, pesticides and the application of cooperation for the manufacture of fertilizers so that group members do not need to buy fertilizer. The existence of institutions/KUD in a village is very helpful for farming communities because these institutions can also take capital loans for farmers so that farmers are able to provide good production facilities, which so far farmers have only relied on outside capital, which is not certain whether they can afford it. continue to cooperate with farmer groups.
