A power system can be said to be reliable if it has a high continuity of service. To achieve this, an operational arrangement is required to optimize installed power to supply the load to avoid overloading or over-supply of the system. Modjopanggoong Sugar Factory Tulungagung is one of the sugar producing industries, where the electrical system in this factory uses two power supply, which is using PLN supply and Turbine Generator Boiler (BTG). The use of more than one power supply resulted in an increase in the required electricity production costs. To solve this problem, in this research will be conducted a study to make efficient of electrical energy cost which is done by arranging supply of electric energy, that is using maximum supply of BTG and its deficiency supported PLN supply (alternative I), using PLN maximum supply and its deficiency is supported BTG supply alternative II) and only use PLN supply (alternative III). The results showed that energy efficiency can be done with the regulation of energy supply at the factory, that is in alternative I with savings Rp.430.025.007 (2.1%), alternative II with savings of Rp. 553,984,815 (2.7%), and alternative III with savings of Rp. 2.055.727.407 (10%).

The article substantiates that the effective use of organic waste for further processing today is a prerequisite for the development of agricultural enterprises, their competitive advantages and ensuring energy and environmental security. The basic principles of enterprise waste disposal are identified, which include: maximum use of on-farm resources, ensuring the economic efficiency of the technologies used, and compliance with veterinary and sanitary requirements. The most common methods for processing organic waste of agricultural enterprises, which include energy and non-energy areas, are investigated. The waste from the plant growing industry can be used for energy purposes in two directions: direct burning in order to obtain heat and electric energy, as well as for the production of solid biofuels. Livestock waste can be used to produce another type of biofuel – biogas. The non-energy direction of the use of organic waste from agricultural enterprises provides the production of secondary products (pulp, paper, cardboard), feed, bedding, compost. It is substantiated that the directions of use of crop waste, which is now preferred by agricultural enterprises, are mainly non-energy (like roughage, litter, as fertilizers) and ineffective (such feed is of little value for highly productive animals, enterprises do not comply with the technology of smelling residues, which minimizes positive effect). Various methods of processing waste products (secondary products) of the livestock industry are analyzed: composting, vermicomposting, composting using gumivit, infusion, and biogas production. A comparison of the economic efficiency of traditional and bioenergy manure utilization at a conditional enterprise is made. It is proved that modern methods of manure utilization with biogas production have advantages because they have an environmental effect, can provide energy autonomy due to the refusal to purchase fuel, electricity, it is possible to increase the efficiency of activities through the sale or own use of biological fertilizers, and the sale of other by-products.

The effectiveness of the electric braking system largely depends on how the braking is carried out, whether the braking characteristics that it forms are acceptable for a given vehicle, how simple and reliable the technical solutions embedded in the system are, and where the braking energy is used. With electric braking, it is possible not only to extinguish the electrical energy on the braking resistor, but also to send it back to the storage device and again use it in traction mode. This paper analyzes the most common methods of electric braking used in electric braking systems for traction electric drives that are in operation on vehicles. As the main criterion for evaluating the method of electric braking, its energy indicators are selected. The results of scientific research of the proposed new method of electric braking, which provides better energy performance and new technical solutions for its implementation, are considered. When implementing this method, DC motors are operated by sequential excitation generators. The current in the field windings is regulated by a DC-DC-converter. Energy in the power circuit is accumulated in storage devices and used in traction mode. When the storage devices are filled, the energy in the power circuit is extinguished by the braking resistor, and the energy from the output of the DC-DC-converter is used for own needs. In this case, braking characteristics are formed as in generators of independent excitation. To increase the braking efficiency at low speeds, it is necessary to smoothly regulate the resistance of the braking resistors by shunting them with transistor switches.
