Coconut plants are common in Indonesia, which is the second largest copra producer in the world. Coconut dregs has never been used before, as result it is one of large wastes in Indonesia. The main problems of coconut dregs were the content of crude fiber and crude fat which are high and low crude protein. Special attention was needed to improve the nutritional content by using fermentation technology. Fermentation was used in this study by using bacteria which had derived from the coconut plant itself called pliek u, isolate (YNH11). This study was conducted for 3 months starting from April to July 2018 at the Animal Production Laboratory and the Laboratory of Animal Food Nutrition Sciences Faculty of Agriculture, University of North Sumatra. This research was designed using a Completely Randomized Design (CRD) factorial pattern of 3 x 3, with 3 replications where remarked as factor 1 was the various levels of bacterial inoculum YNH11 from pliek u and factor 2 was the duration of fermentation (incubation). the parameters measured were water content, dry ingredient , crude protein, crude fiber, crude fat, and ash content using proximate analysis. The results showed that coconut pulp fermentation using bacterial origin of pliek u (isolate YNH11) with the level of inoculum administration and fermentation time had an effect on the measured parameters. it eventually increased water content and crude protein, meanwhile it decresed crude fiber, crude fat, dry ingredient, and ash content as well.

Authors: Ginting S
Published: October 2021

There is large potential for exporting meat goats and so gaining more economic benefit from raising this animal. There are several  constraints faced by the goat producers or  traders in fulfilling the potential demand of the market. Developing a more intensive goat production system is urgently needed in order to increase the capacity of the stock supply while at the same time the goat population is developing to make the system sustainable in the long term.

In intensive goat production system feed play a central component  in achieving  the maximum economic efficiency of the production, since under such production system the feed could contributed  up to 70% of the total  production cost. To reach a high  efficiency in  feed utilization for goat production system  there are at least two feeding system that  could be considered. Feeding system and feed management is aldo critical to be developed intensively to be more well adaptive. Feed budget or feeding standard are some alternative feeding approach for intensive goat production system and feeding strategy and feed  technology are important in  optimizing the level of productivity of goats during each phase of its life cycle and production.

The article is devoted to the definition of approaches to the analysis of changes in the content and nature of work, which occur in the current stage of post-industrial society and are determined by the implementation of areas within the concept of sustainable economic development. The starting point of the study was the use of the method of scientific abstraction in the analysis of labor, on the basis of which it is shown the expediency at the theoretical level to consider human economic activity in the perspective of two aspects. This approach made it possible to clearly distinguish between the concepts of "content" and "nature" of work. Show that the set of labor functions and operations, which are derived from the technical basis of production, technical-technological and organizational-economic relations, form the inner essence of the content of labor. And socio-economic relations between people by their participation in production processes, which are primarily determined by property relations, act as an economic category and determine the external form of labor, ie its nature. It is established that between these characteristics of labor there is always, under each specific conditions of development of social production, a close connection and interaction, which necessitates the simultaneous, comprehensive study of their essence. The paper presents a historical view of the analysis of the content and nature of work by scientists of the Soviet period, which was carried out within the formational approach and aimed at substantiating the advantages of the socialist nature of work over capitalist. To achieve this task, the results of the assessment of the content of labor were set aside, detached from the nature of labor, because the technical and technological basis of production in the countries of the socialist camp lagged far behind that formed in developed capitalist countries. Based on the realities of today, considerable attention in the article is paid to the impact of innovation and information and communication technologies on the content and nature of industrial labor. Particular attention is paid to the study of the processes of intensifying the use of intellectual resources of employees, strengthening the creative nature of work, increasing the focus of man on the need for constant replenishment of knowledge, finding them an applied nature.
EUROPEAN EXPERIENCE OF FUNCTIONING OF CLUSTERS IN THE FIELD OF ENERGY EFFICIENCY AND RENEWABLE ENERGY: LESSONS OF INNOVATIVE DEVELOPMENT
Authors:   State University Luhansk Taras Shevchenko National University, Suvorov Mykhailo
Published: October 2021

In the modern world, attention to the use of renewable energy sources (RES) is increasing. This is primarily due to significant investments in the exploration and development of new oil and gas fields, the approaching threshold of exhaustion of these energy resources and, as a result, the end of the era of cheap oil. In addition, the use of these non-renewable energy sources is largely associated with an increase in carbon dioxide emissions into the atmosphere and an aggravation of environmental problems. According to the energy development strategy of the European Union, energy cluster projects are designed to form and develop ties between the countries. The European Union clusters focus on the following areas: energy, nutrition and health, marine and other industries. The energy cluster includes: wind energy, biomass energy, bioenergy conversion, offshore wind energy, innovative energy ecosystem. The energy cluster of the European Union unites energy companies, promoting the integration of science and technology, creating conditions for the development of competition and cooperation between enterprises in commercial activities. For many years, clusters have been the leading form of providing for regions in the world. And the field of renewable energy is no exception here. We emphasize that this area has It has a pronounced innovation orientation and is able to become a locomotive of innovative processes in Ukraine. Forming and developing clusters in the field of RES, the regions of Ukraine can significantly accelerate their own innovative development and modernize the regional economy. Therefore, the study of foreign experience in the functioning of such clusters is extremely relevant. The high capital intensity of innovative processes in the electric power industry, combined with the significant investment potential of domestic energy companies, make it possible to consider the industry as one of the largest customers for the creation of innovative technologies. The activation of these processes in the energy sector determines the need for systematic management of the joint development of energy enterprises and related industries and areas of activity. The implementation of this approach should be facilitated by the formation and development of energy clusters. The article examines the foreign experience of creating such innovative structures in the industry.
