The selection of the right cost calculation method is of critical importance when it comes to determining the real product profitability (as well as clients and other calculation objects). Traditional cost calculation methods often provide false information. The literature offers many examples of big companies that have given up traditional methods and applied a new method: activity-based costing (ABC). They discovered that many products that are manufactured generate losses and not profits. Managers, based on incorrect calculations, mistakenly believed in the profitability of each product. Turney (1991) reports on an example of an American manufacturer of over 4,000 different integrated circuits. The cost calculation with the allocation of direct production costs as machinery-hour markup demonstrated a profit margin of over 26% for each product. Implementing ABC showed that the production of more than half of the products was not profitable, and having factored in additional sales and management costs (which accounted for about 40% of the total costs), it was as much as over 75%.

To hold the cost of products sold at a competitive level in face of rising prices, it is necessary that production costs be held to a minimum. The first major field of reduction of production costs is in labor costs. In order to get the most out of dairy equipment labor must be properly used. When the time requirements of a job are reduced by improving the method, the worker must be gainfully employed at some other assignment. There are beneficial changes which provide leisure, add to the comfort of the worker, and reduce the hazards of his work. Changes in plant equipment arrangement may be made even though they are not justified on a purely economical analysis. The paper presents principles, with applications, which can be followed in each plant to improve the work method and decrease time requirements.

With the addition of profits, the company can pay all costs that are sacrificed, so that the company's operational activities are guaranteed and can run well. The problems examined in this study are intended to find out how the comparison of recording costs using the full costing method and variable costing affects the net profit of PT Bhaskara Madya Jaya. Both of these methods simultaneously involve raw materials, direct labor costs and factory overhead costs. What distinguishes the full costing method using fixed factory overhead loads and variable, if the variable costing only adds to the variable overhead load. Production costs that are not included in the raw material and direct labor costs are the overhead of the manufacturing plant itself. Descriptive method with a quantitative approach is the model of this research. With the use of saturated sampling. Documentation is a data collection technique that researchers use. The results of the study and details obtained by comparing the full costing method and variable costing. In detailing the cost of production, the full costing method produced a greater than the costing variable, this is due to the full costing method adding all the elements of costs, variable costs or fixed costs . Then from the results of the breakdown of net income, using the full costing method, the nominal profit is found to be far less than using the variable costing method.

This research aims to identify all production costs incurred in production, to calculate the cost of goods manufactured correctly using the Process Costing Method and decision making for determining the selling price of shoes. The research was taken in one of small-sized enterprises shoe factory in East Karawang. The research method is descriptive comparative with a qualitative approach. The descriptive method is used to describe the production costs incurred in the production process including the raw materials costs, supporting materials costs, labor costs, and factory overhead costs. In this research, the data used are primary and secondary data. The COGM calculation results in show that there is variance calculation between company system and process costing method. It is due to calculations that companies do not identify production costs in detail, therefore the company’s COGM calculation is inaccurate. The COGM calculation appropriately can be the company’s strategy to determine the selling price. so that company profits can continue to increase.

Abstract Babar Island is corn production center in District of Babar Islands. Maize is the dominant food commodities and a major food source for the community. Corn is the dominant crop commodity in Barbar Island and become staple food for the community. The farming are traditional and subsystems to meet farmers household needs and the excess (if any) will be sold but in very limited quantities. However the sales purpose is not commercial but just to meet the households needs that can not be substituted by other goods and only by few farmers if necessary. The farming is carried out on slash and burn dry land by polyculture cropping pattern that is combination of annual and perrenial crops. This study aimed to examine the feasibility and profitability of corn farming in Barbar island, using survey methods with stratified random sampling technique. The results showed that the cost of corn production in Barbar Island, district of Barbar Islands, South West Maluku Regency is consisted of fixed cost and variable cost. The fixed cost components is including : equipment depreciation costs and land rent costs. The variable costs includes : inputs costs (seeds, fertilizers, chemical) and labor costs. Variable costs is the largest cost component for corn farming. Corn farming is profitable and viable, as indicated by the average income Rp.2.647.396 compared to the average cost incurred by farmers Rp.2.520.934 and BC ratio of 1.05. This means that the production costs of Rp.2.520.934 will generate benefit 1.05 times of the cost.

Animal husbandry has a longstanding tradition in Serbia, and the production of milk and dairy products has a rich legacy. Cow?s milk is used in the manufacture of all kinds of dairy products. Annual global cheese production is about 20 million tons, with cattle milk cheeses produced in large-scale processing plants constituting about 80% of that production. In Serbia, leaders of milk production are small family dairy farms, which contribute 92% of total production, while dairies with large capacity dominate in milk processing. There are 211 milk processing plants of varying capacities in Serbia. The largest amounts of milk are processed by dairy plants 'Imlek' and 'Subotica', while 188 small-scale dairies process 20% of total milk. The subject of this paper is the analysis of the economic indicators of production of semi-hard and hard cheeses in small-capacity dairies in Serbia. To determine the level and structure of production costs of dairy products, the analytical calculation method of per unit processing costs has been used. The study has revealed that the cost price of semi-hard and hard cheeses in small-capacity dairies amounts to 3.33 ?/kg. With 90.83% in the structure of total costs of processing the milk into cheese, the cost of raw materials has the largest share, followed by labor costs with 6.54%. For small-capacity dairies to be able to compete with larger dairies, both in product quality and price, it is crucial to continuously monitor and minimize production costs.
