Controlling Model of Intangible Assets on Secondary Irrigation System Management

The research aims to develop a controlling intangible assets model on secondary irrigation system management. The method used in this research consists of three stages: model development, collecting the data, and testing of models. Two stages were done in model development; the first stage was building the model of controlling intangible assets in irrigation system management using neuro-fuzzy system, which had three sub models: (i) knowledge management, (ii) intangible assets, and (iii) performance of irrigation system. The second stage was evaluating the model at Molek irrigation system in Malang, East Java. Data collection were done by questionnaire and interview on employees of Kepanjen Irrigation Office. Data analysis was done using Adaptive Neuro Fuzzy Inference System. The model was evaluated using correlation coefficient, Mean Absolute Percentage Error and Root Mean Square Error. The result indicated that the model of controlling intangible assets in irrigation system management could predict the intangible assets and performance of irrigation system. The model linked to knowledge management, intangible assets and performance of irrigation system. Knowledge management was described into four main components: (i) learning organization, (ii) principle of organization, (iii) policies and strategies of organization, and (iv) information and communication technology which control intangible assets on irrigation system. Intangible assets consist of moral intelligence, emotional intelligence, creative attitude, and institutional culture which controlling effectiveness of irrigation system. It can be concluded that the controlling model of intangible assets irrigation systems which built with the principles of neuro-fuzzy can predict the intangible assets and irrigation system performance keywords: Model, Intangible Assets, Controlling, Irrigation System.

Irrigation is a socio-cultural society system that dynamically depend on the environmental conditions 1 .In this early information era, the environment conditions are change rapidly because of rapid development of information technology, globalization and democratization 2 .Social and political reforms in 1998 had caused paradigm shift in the irrigation sector 3 .The reformation demand that the management of irrigation need to be done in a transparent, responsible, and equitable ways.To achieve that goal, intangible assets becomes a very important factor.Intangible assets affect the process of management organization 4,5 and the performance of company 6,7 .The physical development must be accompanied with the non-physical development (intangible).
The problems occured in the management of irrigation systems indicate that intangible assets which consist of moral intelligence, emotional intelligence, creative attitude, institutional culture, and farmers participation are decline 3 , whereas the condition of intangible assets were affected by the performance of the irrigation system.
Consequently, the study of controlling intangible assets in management irrigation system is very important.

MATErIALS AND METhoDS
Molek irrigation area with 3.98 ha in total is the main canal service area that channel the irrigation drain water from the Bendung Blobo that dam up the Bantas River and got addition from Palaan River.Administratively, Molek Irrigation Area comes under the scope of Kepanjen Office, irrigate the land in Malang district that covering 4 districts such as Kepanjen, Kromengan, Ngajum, and Sumber Pucung.
This research method consists of three stages: model development, collecting data, and testing of models.The controlling model of intangible assets in the management of irrigation system was The knowledge management has four variables, i.e learning organization, principles organization, policies and organization strategies, information and communication technology.The intangible assets have five variables; moral inteligence, emotional intelligence, creative attitude, institutional culture, and farmers participation.Each of knowledge management variable is associated with the variable of intangible assets.The performance of irrigation system is measured by its effectiveness.The performance of irrigation system effectiveness is a ratio of the planting area with the land area.The relationship between the variables is like neural network, so that the control model of intangible assets in the management of irrigation system using the principle of neuro-fuzzy system 9 .The structure of intangible assets control model in the management of irrigation system is presented in Figure 1.  5) The mathematical model that expressed in equations from 1 to 5 are a linear equations.This is due to the research variables are measured from the average value so that the relation between variables is a straight line.
The data collected by questionnaire and personal interviews in March -June 2015.The research subjects are the employees of Water Resources and Irrigation Office of Kepanjen, Malang.The intangible assets, knowledge management is classified into 5 categories based on the normal distribution model which assumed that scores of subjects in the population is normally distributed.The categorization is relative so the wide interval can be determined by researcher within reasonable limits and acceptable reason such as:

PS I (Nov-Feb) PS II (Mar-jun) PS III (jul-oct)
The controlling model of intangible assets in the irrigation management system was tested its performance at the Molek irrigation area on Malang, East Java.

rESuLTS AND DISCuSSIoNS
The agriculture land follows the patterns of planting seasons; planting season I (PS I), planting season II (PS II), and planting season III (PS III).Each of planting seasons use 4 months period so it is expected that the water availability can be utilized in a fair and equitable way.
Most of residents in the Molek irrigation area worked as farmers.The irrigation management of Molek irrigation area generally in good condition because the farmers can fished throughout the year (except in the downstream of PS III).
Table 1 showed that during planting season (PS I), from upstream to downstream in the agricultural lands of Molek irrigation area are planted with rice, which means land condition at PS I is sufficient with water.Rice also planted at PS II in upstream and middle regions, but in the downstream areas were planted with corn crop.This implies that the PS II irrigation water current began to decline and the water availability is not sufficient in downstream area for rice cultivation.
The farmers in the downstream area use the existing irrigation water for the crops cultivation with rotation system so that the land can beutilized to improve their welfare.At PS III from upstream to the middle of agriculture land in Molek irrigation area also planted with rice, while the downstream area is in fallow condition.This implies that the PS III irrigation water flow decreased and there was no enough water for rice cultivation at downstream area.All farmers in Molek irrigation area (except in the downstream), use the existing irrigation water for rice cultivation with rotation system.The timing and amount of water is determined by Kuwowo, a villager which responsible for managing the irrigation.
The knowledge management of secondary irrigation system which represented by employees of Water Resources and Irrigation of Kepanjen Office, Malang is presented in Table 2.
Table 2 showed that 66.7% employees have very poor learning organization level.This implies that the employees are mature person, shared vision, systems of thinking, mental models, and very poor of team learning.Approximately 11.1% employees have a very poor level principles organization.They are less understand about objectives formulation, labor division and delegation of power, authority ranges, levels of supervision, unified command and responsibilities and coordination.Around 33.3% employees have sufficient level of policy and strategy organization.They have a unified and integrated plan linking organizational excellence with environmental challenges, which are designed to ensure that the main organization purpose can be achieved through appropriate implementation by the organization.Most employees (77.8%) have a very poor level of understanding and use of information and communication technology.
Intangible asset of secondary level irrigation system which represented by employees of Kepanjen Water Resources and Irrigation, Malang, consists of moral intelligence, emotional intelligence, creative attitudes, and institutional culture which presented in Table 3.
Table 3 showed that all employees (100%) have a good moral intelligence.The employees have a good willingness to integrate the universal values into their behavior, responsible for committed acts and understand the consequence, trying not to harm the others, and compassionate.Around 92,6% employees have emotional intelligence in good category.Most of employees have a good ability to understand their emotions appropriately and accurately in a variety of situations, managing emotions well, striving to achieve the goals with quite enthusiastic attitude, passion, strong self-confidence, positive thinking and understand the emotion of other action that appear and interact positively with others.
Approximately, 74.8% employees have creative attitude in good category.Most of the employees have a good ability to use their ideas to solve a problem, finding a wide variety of ideas to solve problems outside the usual categories, providing a unique or extraordinary response, and the direction of the idea expressed in detail to make it into reality.About 77.2% employees have institutional culture in good category.The employees' behavior of Molek irrigation system in secondary level have been in line with the institution's goals, decisions are taken by consensus, thinking in order to achieve similar goals, the existence of family relationship, the farmers welfare is a priority that has the spirit of continuous learning progress, reward for achievement employees and making decision based on empirical data.The effectiveness of the secondary level of Molek irrigation area in 2014 is presented in Table 4.
Table 4 showed that the most of the land in the secondary channel services (96.3%) have a very good level of effectiveness.Most of the areas are able to be planted well.
The controlling model of intangible assets in irrigation system management has two sub models; relationship model between knowledge management with intangible assets and relationship model of intangible assets with irrigation system performance.
The relationship between knowledge management consists of a learning organization (LO), the principle of organization (PO), the policy and strategy (PS), information and communication technology (ICT) with intangible assets tertiary level of irrigation system which consist of moral intelligence (MI), emotional intelligence (EI), creative attitude (CA), institutional culture (IC) is expressed in the equation 9  4 showed that the correlation coefficient (r) between intangible assets predictions with actual intangible assets value at 0.67-0.89.This implies that the relationship between predictions intangible assets with actual intangible assets is strong.The error model in predicting intangible assets have a small value which indicated by MAPE (0.06-0.12) and MRSE value (2.21-4.38).MAPE value showed the deviation of the actual data against the average.The smaller of RMSE value indicates good score (Table 5).
The relation between intangible assets consisting of moral intelligence, emotional intelligence, creative attitudes, cultural institutions with the effectiveness of the irrigation system of secondary level expressed in equation 13.EF = 0.00002498+0.002143MI+0.001068EI+0.00109CA+0.001008IC

…(13)
The correlation coefficient (r) between the effectiveness of irrigation systems predictions with the actual effectiveness of irrigation systems was 0.76, which means that the relationship between the Error models in predicting the effectiveness of small irrigation systems shown by MAPE value is 0.02 and 0.15 for MRSE.MAPE value showed the deviation data of predictions with actual system, while MRSE indicate deviation data of actual with the value so that the model is adequate.
