<em>The State University of Papua (UNIPA) provides human resources for agricultural sector in Tanah Papua through the Department of Agricultural and Agricultural Technology (FAPERTEK). However, in the process of generating these human capitals, many of its alumni could not finish their study within the targeted time frame designed by curriculum used in this department. Thus, this research aims for understanding factors that influencing the study time of FAPERTEK-UNIPA�s alumni. Study time data was obtained through a census from secondary data whereas evaluation of the study time was conducted through a survey to alumni. The evaluation was focus on two sub-systems:� student and the interaction between students and faculties. The result shows that in general alumni at the bachelor (S-1) level and at the diploma (D-3) level finished their study more than 10 semesters and 7 semesters consecutively. Financial problem, difficult and lengthy research topic, communication problem with advisor, many re-taking classes, health problem as well as personal problems were among the reasons for those alumni whose study time exceeds the minimum time as indicated by the curriculum. Academic advisors who are expected to assist students to be able to finish their study within the allotted time have not performed efficiently according to some of respondents. Information provides through this research is expected to be beneficial for enhancing current and future education system in this department.</em>

Energy is one of the main pillars of the state’s economy, which is currently facing serious problems due to depletion of mineral energy resources and the threatening environment. As a result, presently around the world there is a rapid growth and development of energy-efficient technologies and the use of renewable energy sources (RES), providing an increase in energy resources, as well as environmental and social effects. One of the most relevant and promising areas of renewable energy development is the disposal and processing of organic waste in biogas plants, and this is particularly relevant in agricultural regions. In this regard, this paper considers the state and prospects for the development of bioenergy in agricultural regions of Uzbekistan, where half of the population of the republic lives. The potential of organic waste from livestock and poultry farming of the agricultural sector was determined, and it was revealed that the use of biogas plants for the disposal of manure and litter is clearly a profitable production and requires close attention from rural producers. The introduction of biogas technologies for the bulk of agricultural producers is an urgent task, that will ensure not only a solution to the waste problem, but it will also provide a solution to energy, agricultural, environmental and social problems in rural regions of the republic.

The Mathematical Model

A complex of tasks that can be solved using mathematical models of the dependence of consumed energy resources on influencing factors are considered in the article. The main type of model for industrial consumers with a simple relationship between energy and technology, is the one-factor model “consumed energy resource-volume of output”. For industrial consumers with a complex relationship between energy and technology, the mathematical model of the dependence of energy resources on technology is determined by several factors. Methods for assessing the current state of energy efficiency, as well as predicting it for the future in the context of the introduction of energy saving measures and changes in the production program were proposed.
