The article deals with the main problems of port elevators, which lead to incomplete use of their capacities. They include: the problem of reducing the capacity factor of the elevator capacity, the problem of lack of rhythm of grain picking operations, the problem of inconsistency with railway transport, the problem of storage of different crops and crops of different quality, the problem of loss of time during the shipment of grain to the ship. The necessity of detailed planning of port elevators' operations by the determination of flows of work passing through the system, as well as the control of their implementation, is proved. The graphical model of implementation of the operational function of the port elevator is suggested, which will allow to coordinate its operations and to check the possibility of their implementation during the departure period of the ship. This model establishes the order of operations, as well as the main planning documents that regulate them. The use of a technological map of the implementation of the operational function for describing the list and sequence of basic operations for the formation of a ship batch and its shipment, conditions and requirements for their implementation, as well as information about the equipment used, is suggested. The graphical model and the technological map of the implementation of the port elevator's operational function provide information on the rational sequence and coherence of the operations' planning for the formation of the ship party and its shipment, which reduces the time loss, provides the opportunity to coordinate the work of the elevator with its transportation system.

The article presents the results of research on the determination of rational technological parameters for the production of culinary products using dry mixtures and emulsions based on animal raw materials for additive technologies. It was found that when making products using mixtures and emulsions based on broiler chicken meat, as well as a combination of broiler chicken meat and pork, pork and beef (ratio 1:1) rational height of the layer, which makes it possible to ensure stability and safety of the product shape (with a fixed diameter of the opening of the culinary syringe – 7 mm and the optimal length of the layer - 100 mm), is from 14–21 mm (with a layer width of 7 mm) and up to 133–154 mm (with a layer width of 98 mm), which allows for improved structural and mechanical (SSL – 1090.7–1099.9 Pa) and functional and technological indicators of these products (WHC – 92.7–97.5%). The rational sequence of application and the duration of chopping of the main and auxiliary raw materials for the manufacture of emulsions, the duration of preparation (3 minutes), the degree of hydration (1:2 – 1:3) and the temperature of water for the reduction of dry mixtures (60±1° C) were established, which made it possible to develop technological schemes for the production of culinary products using additive technologies.

Capacity of railway blocks and sections is one of the most important parameters of railway transport operation. The purpose of the study is to find a universal parameter of railway blocks and sections capacity that would allow maximum use of the reserves available. This paper proposes to use “partial capacity filling factors”, which are defined as the ratio of the changed capacity factor to the existing value, as a relative indicator. The methodology of application of this indicator has been elaborated, examples of calculations have been provided. There are nomograms in the paper that allow determining the maximum number of trains that can be passed through the section taking into consideration all conditions of operation.

A concrete placing boom is the final element of concrete mixture pipeline transportation system. It is designed to deliver the concrete mixture for discharging where and when required, therefore, similar to cranes, it must be equipped with at least two mechanisms: boom extension and rotation. The mechanisms can be both manually and hydraulically actuated, hence, booms are differentiated between mechanical (manually controlled) and hydraulically or electrically controlled. This article aims at describing the areas for using various categories of concrete placing booms.

Pasar Loa Kulu beroperasi setiap hari mulai pukul 06.00  – 17.00 WITA dan dikelola oleh Unit Pengelola Pasar. Pengelolaan sampah di pasar ini belum terkelola dengan baik sehingga perlu adanya pengelolaan. Tujuan dari penelitian ini adalah mengetahui karakteristik sampah dengan merancang dan merekomendasikan pengelolaan sampah pada sistem pemilahan, pewadahan, pengumpulan, dan pengangkutan sampah. Sistem pemilahan dan pewadahan dilakukan dengan menghitung jumlah timbulan dengan hasil rata-rata 540,62 kg/hari dan karakteristik sampah berupa sampah organik sebanyak 492,95 kg/hari dan anorganik 47,66 kg/hari. Direkomendasikan dengan memberikan bak sampah berdasarkan karakteristik agar tidak tercampur. Sistem pengumpulan dilakukan dengan mengumpulkan sampah dari bak sampah hingga ke truk dan ditentukan alternatif rute pengumpulan sampah. Dibuat 3 alternatif rute pada bak sampah belakang dan rute optimum berada pada rute 1. Bak sampah depan dari 2 rute alternatif dipilih rute 2 sebagai rute optimum. Sistem pengangkutan dilakukan penentuan alternatif rute yang efektif dan efisien dengan menggunakan perangkat lunak Arcgis 10.1. Sistem pengangkutan direncanakan dibuat celah pada bak truk sampah antara sampah organik dan anorganik dan dibuat 3 rute alternatif dari Pasar hingga ke TPA Bekotok. Sehingga dipilih rute 1 sebagai rute yang efektif dan efisien.Kata kunci: Pasar, Pemilahan, Pewadahan, Pengangkutan, Pengumpulan. Loa Kulu market operate every day starting at 06.00–17.00 WITA and managed by Unit Market Managers. Waste management in the market has not managed well by  market manager so that required management. The purpose of this research is knowing characteristic garbage to design and recommends waste management on system sorting, containers, collection, and disposal. The system sorting and containers done by counting the number of  pileup with the results average 540,62 kg/day and characteristic of the waste in from organic waste as many as 492, 95 kg/day and inorganic 47,66 kg/day. Recommended by giving a garbage based on characteristic that not mixed. Collection system done with gathering trash from garbage bins to dump truck and determined alternative routes garbage collection. Made 3 alternative routes garbage bins back and route steady be on a route 1. Gabage bins in front of 2 alternative route chosen route 2 as steady route. Transportation system done determination of an effective and efficient by using software Arcgis 10.1. Transportation system planned made a gap in the dump trucks between organic waste and inorganic and made 3 alternative route from market to landfill Bekotok. So chosen route 1 as the route effective and efficient.Keywords: Collection, Containers, Market, Sorting, Transportation.
