COST ANALYSIS OF WATER RESOURCES MANAGEMENT SERVICES BELANTI II IRRIGATION AREA CENTRAL KALIMANTAN PROVINCE

The Belanti II Swamp Irrigation Area in Pulang Pisau Regency, Central Kalimantan, spans 3,275 Ha. Water management activities, necessitated for sustained irrigation, incur the Water Resources Management Service Fee (BJPSDA), calculated on cost recovery principles. This study aims to (1) Determine the BJPSDA value by considering the economic benefit factor, (2) Assess farmers' Ability To Pay (ATP) and Willingness To Pay (WTP) for BJPSDA, and (3) Evaluate the Belanti II swamp irrigation network and optimization efforts. The BJPSDA in Belanti II is Rp5,625,504,000, with agricultural benefits contributing Rp51,468,721,052.40 (51.86% of NME). The cost is Rp570,151.69/Ha or Rp101/m3. Farmer ATP and WTP for BJPSDA are Rp54/m3. The irrigation system lacks proper water flow regulation structures, but optimization efforts include channel normalization and water control structures. To enhance leaching ability, 500 m3/ha/day of fresh water is needed. Structures like weirs and flap gates regulate water supply during high and low tides, respectively. These initiatives aim to ensure consistent irrigation and sustainable water resource management in Belanti II.


INTRODUCTION
Water management in swampland is not only intended to avoid excessive flooding in the rainy season but must also be intended to avoid drought in the dry season.Water management that merely controls inundation in the rainy season by creating drainage channels will cause drought in the dry season.According to their location and function, channels are divided into four: 1.Primary channels are channels that carry water from the main building to the final building.2. Secondary channels are channels that carry water from the divider channel in the primary channel to the final building.3. Tertiary channels are channels that function to irrigate one tertiary plot, which takes water from secondary channels or primary channels.Quaternary channels are channels in paddy fields and take water directly from tertiary channels.
Irrigation Area (DI) Belanti II Unit Pandih Batu Subdistrict, Pulang Pisau Regency, Central Kalimantan Province has an area of 4,500 ha, functional area of 3,275 ha, primary channel 8.7 km (1 section), secondary channel 221.03 km (100 sections), collector channel 6,000 meters, covering 2 villages, namely Belanti Siam Village with a total of 836 tenant farmers, planting area of 2,096 ha and Gadabung Village with a total of 476 tenant farmers, planting area of 1,179 ha.The assisted farmers in Belanti Siam Village consist of 22 farmer groups (4 PPPA) and in Gadabung Village consist of 12 farmer groups (4 PPPA).
The form of farmers' participation in irrigation management is in the form of fees managed by the Water User Farmers Association (HIPPA) or Water User Farmers Association (P3A).If farmers' participation is taken into account as part of the Water Resources Management Service Fee (BJPSDA), it will be a deduction for government subsidies in the agricultural sector.The role of farmers' BJPSDA in irrigation management in Rawa Belanti II in Pulang Pisau District is currently realized in the form of Irrigation Services Fee (IPAIR) paid by farmers in HIPPA.The amount of IPAIR paid by farmers in DI Rawa Belanti II is currently only an agreement between farmers and HIPPA of Rp 24,000/ha or Rp 56/m3.
According to Sangkawati (2009), to carry out water resources management according to the principles of needs management and increase BJPSDA revenue, it is necessary to conduct research analyzing the correlation between management service fees and beneficiaries in accordance with applicable regulations, joint commitments, and cost contributions to be determined, there must be an understanding of interested parties with criteria that must be met.Anwar & Utomo (2013) in their research explained that the calculation of BJPSDA is influenced by the quality of water services and the value of economic benefits of water users.Meanwhile, the Regulation of the Minister of Public Works No. 18/PRT/M/2015 also explains that the calculation of BJPSDA must take into account the weight of the economic interest value of water users.
This study aims to (1) Determine the value of the Cost of Water Resources Management Services (BJPSDA) irrigation by considering the value factor of economic benefits, (2) Determine the value of Ability to Pay (ATP) and Willingness to Pay (WTP) farmers in making payments Cost of Water Resources Management Services (BJPSDA) irrigation.The results of this study are expected to produce BJPSDA irrigation in accordance with the costs required for the operation and maintenance of irrigation networks and the benefits of irrigation water received by farmers to ensure the quality of irrigation services, while still considering the ability and willingness of farmers as water users to pay BJPSDA, (3) Knowing the condition of the Belanti II swamp irrigation network and the efforts that have been made to optimize water management.

LITERATURE REVIEW 2.1. Irrigation
Irrigation Anonymous (2002a) is a collection of human efforts in terms of (1) distributing water from water sources, (2) distributing water to channels, (3) then dividing water to the land, (4) flowing it to agricultural/non-agricultural crops, and (5) excess water is released through drains.As for other definitions of irrigation, some say that irrigation Anonymous (2006) is an effort to procure, regulate and dispose of irrigation water to support various agriculture ranging from surface irrigation, swamp irrigation, underground water irrigation, pump irrigation, and pond irrigation.
In order to increase the area of rice fields that have irrigation, irrigation extensification and irrigation intensification activities can be carried out.Extensification and intensification of irrigation include (Iswandari, 2003): a. Maintaining the quality of irrigation so that it is expected that the quality function of irrigation can be improved, at least not decreased.b.Tertiary network construction projects and paddy field printing can be completed immediately so that they can fully support the work of the main irrigation network.c.Immediate rehabilitation of damaged irrigation networks d.Immediate completion of pending irrigation projects 5. Development of new irrigation covering rain-fed rice fields that are considered to have good potential both technically and economically.

Irrigation System
The social physical elements of irrigation systems include Anonymous (2002b) human elements, natural and environmental elements, physical elements, plant elements, and irrigation operation and maintenance techniques.The irrigation system Small & Svendsen (1990) is a unity of social physical elements that are used to distribute water from natural water sources to irrigated land.This irrigated land can be for agricultural crops and nonagricultural crops.
Irrigation system management is needed to help distribute water more effectively and efficiently.The scope of the irrigation system Anonymous (2006) is irrigation infrastructure, irrigation water, irrigation management, irrigation management institutions and human resources.So it can be concluded that the irrigation system can work optimally if there is a strong integration between human resource asset management and non-human resource asset management such as nature, crops, physical irrigation networks.

Water Resources Management Service Fee
The degradation of irrigation infrastructure functions is caused by excessive shifts in groundwater levels, the number of nuisance plants in drainage channels, and sedimentation along irrigation networks.While the causes of degradation of irrigation operation and maintenance include (Sumaryanto, 2006): a.No good progress on farmers' ability to finance irrigation operation and maintenance b.Inefficient institutional system due to free rider and rent seeking practices c.Irrigation institutional design is not in line with user aspirations Reform of the management system in the irrigation system that has been going on for a long time must be immediately implemented and intensively socialized to farmers.Some experts are more inclined to increase the efficiency of irrigation through a supply management approach.But there are also those who think it would be more effective and relevant if the increase in irrigation efficiency through demand management approach.
Indonesian farmers have been using a supply management approach (Sumaryanto, 2006).If Indonesian farmers still use this method in the short-medium term it can still be tolerated although improvements in operational aspects in the field still have to be improved.

105
In the long term, this supply management approach is no longer feasible because it tends to be ineffective and is exacerbated by the decreasing supply of irrigation water with the increasing economic value of irrigation water.Examples of supply management approaches include: 1. Implementation of low flow management system 2. Low flow management 3. Intermittent flow pattern This phenomenon of decreasing water quantity inversely proportional to the increasing economic value of irrigation water has led to the creation of a new approach.This approach is the demand management approach.There are two paths in the demand management approach (Sumaryanto, 2006), among others: a.Output maximization strategy by obtaining maximum output or income through available irrigation water.This strategy is most effectively used in conditions where people do not understand the high economic value of irrigation water.b.The strategy of reducing inputs by reducing the quantity of irrigation water used in producing a certain amount of output.This strategy can be applied when the community's understanding of the economic value of irrigation water is based on economic considerations.Where irrigation water in this case already has a high economic value.Coupled with irrigation system facilities and infrastructure that greatly support the work of farmers.
The condition of the Indonesian people who do not understand and cannot accept the high economic value of irrigation water is more suitable to use a demand management approach through an output maximization strategy.However, there are still weaknesses in the output maximization strategy (Sumaryanto, 2006), namely: a. Implementation is difficult to cover very large irrigation areas, especially when the land involves diverse farming community cultures.b.The accuracy of cropping pattern design and physical infrastructure support is very influential on efficiency.c.This pattern is still considered less aspirational and less popular in the era of democracy

Method of Calculation of Irrigation Water Resources Management Service Fee
The method of calculating the service fee for irrigation water resources management is: 1.Even so, farmers as tax subjects still need to be consulted about the impact of these regulations on their purchasing power in their daily lives.This is done in order to create equitable justice for the use of water economic resources.The purchasing power of farmers can be analyzed using several methods, two of which are Ability To Pay and Willingness To Pay.
According to Tamin et al (1999) Ability To Pay (ATP) is the purchasing power of a person or group to pay for services obtained on the basis of ideal considerations.So in this case the ATP analysis approach is based on the allocation of 6 n cost of irrigation water resources management services and income earned by farmers.So to summarize, ATP in this case is the ability of farmers in terms of making payments for the cost of irrigation water used.Tamin et al (1999)is the willingness of users to incur some costs for the use of services used.The approach to the WTP method in terms of the cost of irrigation water resources management services is done on the basis of perceptions of irrigation water users (farmers) on the cost of irrigation water resources management services.Then the factors that affect WTP (Tamin et al., 1999).
Farmers' WTP for IPAIR tariffs in this study was analyzed through a survey by distributing questionnaires with a question format developed from the contingent valuation (CV) method.This CV technique pays more attention to environmental factors.Through CV can help estimate the value of the unity (contingent) of several alternative scenarios surveyed to respondents (Setiawan, 2005).This CV method includes: a. Open ended CV Method This method has been used less frequently because it takes too much attention to the environment.In general, respondents may be confused because they are unfamiliar with it.If this method is used, the results can be inaccurate (the survey results can show that the respondent's WTP is not the maximum).b.Referendum CV Method Through this method, respondents are asked questions with two alternatives.One option can be selected from the two alternatives.Usually, respondents are only given "yes" or "no" answer options.
The WTP value of each respondent is the maximum rupiah that farmers are willing to pay.To get the average value of WTP, the following equation can be used: where: MWTP = average WTP, in rupiah per cubic meter (Rp/m3) n = number of samples WTPi = maximum WTP value of respondent i The basis that can be used in setting tariffs (Tamin et al, 1999) are: 1.In setting the tariff, it is recommended not to exceed the ATP value 2. If the proposed tariff is between the ATP and WTP values, it can be accompanied by improvements in the level of service.3.If the proposed tariff is below the tariff calculation and above the ATP then the difference can be used as a subsidy burden that must be borne by the regulator (government).4. If the tariff of a vehicle type is below ATP and WTP, there is flexibility in setting a new tariff value.This difference can be used to cross-subsidize other vehicles whose tariff calculation exceeds the ATP value.

RESEARCH METHOD 3.1. Location and Time of Research
The research location is the Irrigation Area (DI) Belanti II Unit Pandih Batu Subdistrict, Pulang Pisau Regency, Central Kalimantan Province, which has an area of 4,500 ha Raw Area, 3,275 ha Functional Area, 8.7 km Primary Channel (1 Section), 221.03 km Secondary Channel (100 Sections), 6,000 meters Collector Channel covering 2 villages, namely Belanti Siam Village with a total of 836 families of tenant farmers, 2,096 ha planting area and Gadabung Village with a total of 476 families of tenant farmers, 1,179 ha planting area.The research time was 4 months.

Population
The population of this study are all farmers who are members of HIPPA (Association of Water Using Farmers) ranging from land owners and land tenants in the Belanti II Swamp Irrigation Area, Pandih Batu District, Pulang Pisau Regency, Central Kalimantan Province.

Sample
The farmers sampled for the study were farmers who were members of HIPPA.The total population of farmers in the Belanti II Swamp Irrigation Area in Pandih Batu Subdistrict, Pulang Pisau Regency is 1,312 farmers, covering 2 villages, namely Belanti Siam Village with 836 families (64%) and Gadabung Village with 476 families (36%).

Research Instruments
The research instrument is a questionnaire, used as a means of communication with respondents to obtain data.The data obtained and collected comes from filling out a questionnaire in the form of an opinion on a statement directly by the respondent, which relates to the variables of project activities.The list of statements used is only intended for objective types of statements with predetermined opinion choices.The ability and purchasing power of farmers to pay for IPAIR can be calculated through the ATP method and the WTP method.The components of the ATP equation can be described as follows: 1. Income (I) 2. Expenditure on irrigation costs (C) 3. Total irrigation water discharge used (D)

Willingness To Pay
According to Tamin et al (1999), Willingness To Pay (WTP) is the user's willingness to pay a certain amount for the use of services used.The approach to the WTP method in terms of the cost of irrigation water resources management services is carried out on the basis of the perceptions of irrigation water users (farmers) of the tariff cost of irrigation water resources management services.Farmers' WTP for IPAIR tariffs in this study was analyzed through a survey by distributing questionnaires with a question format prepared from the contingent valuation (CV) method.Comparative Analysis of ATP and WTP Values Three conclusions can be drawn, namely: 1. ATP value is greater than WTP value Describes the ability of users (farmers in Rawa Belanti II) to pay more than the desire to pay for the service in question.2. ATP value is smaller than WTP value Describes a user's willingness to pay irrigation rates greater than his or her ability to pay.Usually occurs when the utility of the service is relatively very high compared to the low income of the service user.3. ATP value is equal to WTP value Describing between the ability and desire of farmers to pay irrigation tariffs is the same, because there is a balance of user utility with the costs incurred to pay for irrigation services.There are four basic guidelines that can be used in setting tariffs (Tamin et al, 1999), namely: 1) In setting the tariff, it is recommended not to exceed the ATP value 2) If the proposed tariff is between the ATP and WTP values, it can be accompanied by improvements in the level of service.

3)
If the proposed tariff is below the tariff calculation and above the ATP then the difference can be used as a subsidy burden that must be borne by the regulator (government).

4)
If the tariff is below ATP and WTP, there is flexibility in setting the new tariff value.This difference can be used to cross-subsidize other vehicles whose tariff calculations exceed the ATP value.

Value of Economic Benefits (NME)
The profit earned from agricultural activities is the value of agricultural economic benefits (NME).The NME of agriculture can be calculated from the revenue from the sale of agricultural products minus the total production costs incurred.The scope of this research is the Belanti II Unit of Pandih Batu Sub-district, Pulang Pisau Regency, Central Kalimantan Province, which includes 2 villages, namely Belanti Siam Village with a total of 836 tenant farmers, a planting area of 1,500 hectares.2,096 ha and Gadabung Village with 476 tenant farmers, planted area 1,179 ha.The assisted farmers in Belanti Siam Village consist of 22 farmer groups (4 PPPAs) and in Gadabung Village consist of 12 farmer groups (4 PPPAs).Source: Central Kalimantan Provincial Agriculture Office, 2020 The results of Table 3 can be seen that the total area of rice fields in the Belanti II Irrigation Area is 3,275 Ha, with the lowest cropping index in Gadabung which is 146% and the highest in Belanti Siam at 162%.While the highest planting productivity for rice is in Belanti Siam at 3.27 tons / ha and the lowest planting productivity for rice is in Gadabung at 3.19 tons / ha.To determine the value of revenue from agricultural products, it is calculated by multiplying the number of harvests by the selling price of grain.The number of harvests is calculated by multiplying the land area of each region by the planting index and planting productivity as follows: Source: Central Kalimantan Provincial Agriculture Office, 2020 The results of Table 6 can be analyzed that the total economic benefit value of rice is Rp51,468,721,052.40.The lowest economic benefit value of rice is in Gadabung amounted to Rp15,859,359,529.20.The highest economic benefit value of rice paddy is in Belanti Siam at Rp35,609,361,523.20.

Irrigation Water Resources Management Service Fee
The institution that manages activities in DI Belanti II is the Public Works Office of Central Kalimantan Province.In this study, secondary data on the cost of water resources management services in the form of data on the Real Needs of Operation and Maintenance Costs (AKNOP) obtained from the Public Works Office of Central Kalimantan Province.Recapitulation of the Real Needs of Operation and Maintenance (AKNOP) of Irrigation Areas as follows: The recapitulation of the real need for water resources management costs in DI Belanti II based on Table 7 was found to be Rp 5,625,504,000.

BJPSDA Irrigation Value
The units of economic benefit value and the volume or production produced are as follows: The value of BJPSDA is done by multiplying the percentage weight of the economic benefit value by the total cost of water resources management, then divided by the volume or production produced, as follows: BPJSDA Agriculture: The recapitulation of the real need for water resources management costs in DI Belanti II based on Table 7 was found to be Rp 5,625,504,000.The management cost for irrigation according to the NME weight is 51.86% multiplied by the total management cost of Using the help of the SPSS program, the corrected correlation coefficient is obtained from the Corrected Item-Total Correlation as follows: What is the water demand on the land Are you always fulfilled?P4 0,869 If the water needs of the land have not been P5 0,870 met, then is there any form of action?followup from the irrigation manager?Are there alternative water sources when land water needs are not met?P6 0,866 What is the rate of irrigation fees paid P7 0,860 has been commensurate with the service?
Source: Data processing results, 2022 From table 12, it is obtained that all α values> 0.6, then Ho is rejected, meaning that all questionnaire variables are quite reliable or consistent in performing their measuring functions.

c. Respondent Characteristics
The questionnaire was distributed to farmers who are members of HIPPA as a research sample of 307 farmers in the Belanti II Swamp Irrigation Area in Pandih Batu Sub-district, Pulang Pisau District, covering 2 villages, namely Belanti Siam Village with 195 tenant farmers 64% and Gadabung Village with 112 tenant farmers 36%.
The characteristics of respondents include nine criteria, namely age, gender, region, marital status, number of family members, latest education, length of farming, land size, and land status.Respondent characteristics are presented in descriptive form as follows: 1) Characteristics of respondents based on age  Table 13 and Figure 2 show the frequency of the highest to lowest age ranges are respondents 41 -50 years 125 people (41%), 51 -60 years 69 people (22%), 31 -40 years 59 people (19%), 61 -70 years 38 people (12%), more than 70 years 12 people (4%), 20 -30 years 4 people (2%), the age of the youngest respondent was 28 years and the oldest was 76 years.

Figure 10. Composition of Respondent Characteristics Based on Land Status
Source: Data processing results, 2022 Figure 10 shows the composition of respondents with land status of 77% owned and 23% rented.
IPAIR Base Rate in Belanti II The form of farmers' participation in irrigation management is in the form of fees managed by the Water User Farmers Association (HIPPA) or Water User Farmers Association (P3A).If farmers' participation is accounted for as part of the Water Resources Management Service Fee (BJPSDA), it will be a deduction from government subsidies in the agricultural sector.The role of BJPSDA farmers in irrigation management in DI Rawa Belanti II Pulang Pisau Regency is currently realized in the form of Irrigation Services Fee (IPAIR) paid by farmers in HIPPA.The amount of IPAIR paid by farmers in DI Rawa Belanti II is currently only an agreement between farmers and HIPPA of Rp 24,000/ha or Rp 56/m3.

3) Total irrigation water discharge used (D)
Questionnaire results from 307 samples obtained the smallest irrigation water use per planting period of 275 m3.The largest irrigation water use per planting period was 610 m3.Then the average irrigation water use per planting period was 363 m3.The frequency and composition of the percentage of respondents using water for each planting period is as follows.Source: Data processing results, 2022 Table 24 and Figure 13 show that the highest to lowest frequency of irrigation water use range for each cropping period is 301 -600 m3 240 people (78%), 0 -300 m3 65 people (21%), more than 600 m3 2 people (1%).
The calculation of individual ATP can be calculated using the equation: An example of individual ATP calculation for the 1st respondent is: The calculation of the second respondent up to 307 can be done in t h e same way using the equation.Furthermore, the frequency distribution of ATP is as follows: Table 25 shows that respondents who were able to pay Irrigation Water Service Fees (IPAIR) of Rp1/m3 to Rp20/m3 were 90 people (29%), who were able to pay IPAIR Rp21/m3 to Rp40/m3 were 103 people (34%), 3383 people (27%), those able to pay IPAIR of Rp41/m3 to Rp60/m3 as many as 22 people (7%), and those able to pay IPAIR of more than Rp80/m3 as many as 9 people (3%).The results of table 26 can be described that 10% of respondents were able to pay Rp110.00/m3, 20% of respondents were able to pay Rp100.00/m3 , 30% of respondents were able to pay Rp86.24/m3 , 40% of respondents were able to pay Rp73.11/m3 , 50% of respondents were able to pay Rp62,14/m3 , 60% respondents were able to pay Rp49.77/m3 , 70% respondents were able to pay Rp39.04/m3 , 80% respondents were able to pay Rp29.68/m3 , 90% respondents were able to pay Rp17.27/m3 , 100% respondents were able to pay Rp10.36/m3.

Willingness To Pay (WTP)
Willingness To Pay (WTP) is the user's willingness to pay a certain amount for the use of services used.The WTP approach to the cost of irrigation water resources management services was carried out on the basis of irrigation water users' perceptions of the cost of irrigation water resources management services through a questionnaire distribution survey as follows: Source: Data processing results, 2022 Table 27 shows that: a.There are 98 farmer respondents who are aware of irrigation fees b.There are 73 respondents who have paid irrigation fees, meaning that there is still an information gap to farmers about the importance of discipline in paying irrigation fees to HIPPA.c.There were 211 farmer respondents who used the pump system in meeting irrigation water needs so far.So more than 50% of farmer respondents have to spend more money and energy to irrigate their fields.

Comparative Analysis of ATP and WTP Values
A comparison of ATP and WTP values can be seen in the following: of revenue for BJPSDA irrigation (%) D = Quantity of irrigation water utilized by farmers (m)³ Willingness To Pay (WTP) according to Figure 1.Flowchart of Research Design can be used in determining the sample size with the following formula: where: n = sample size N = population size e = 5% sample selection error percentage The simple random sampling method was used in the sample selection with the following details: a. Belanti II irrigation area only has 1 irrigation network in the Belanti II Swamp Irrigation Area of Pulang Pisau Regency.b.The sample of farmers who became the research sample were farmers who were members of HIPPA in the Belanti II Swamp Irrigation Area of Pulang Pisau District, totaling 1,312 farmers.With the Slovin formula, the number of farmer samples obtained was 307 farmer samples.The calculation of the farmer sample is as follows: Based on the number of samples, obtained: a. Number of farmer respondents Belanti Siam Village = 307 x 64% = 195 respondents b.Number of farmer respondents Gadabung Village = 307 x 36% = 112 respondents 2) Reliability TestThe questionnaire reliability test used is the Cronbach's Alpha test.The Cronbach's Alpha test steps are as follows: a) Determine the reliability test hypothesis Ho: α ≤ 0.6: the questionnaire is not reliable H1: α > 0.6: the questionnaire is reliable.b)Test statisticsWhere: α : Cronbach's Alpha value k : number of statement variables S2 : the variance value of each variable statement S2 : variance value of the total variable statement c) If α ≤ 0.6, the questionnaire is not reliable If α > 0.6, the questionnaire is reliable3.7.Respondent CharacteristicsAfter testing the validity and reliability of the questionnaire, the questionnaire was distributed.The questionnaires were distributed to 2 villages in Belanti II District, Pulang Pisau Regency, with a total sample size of 307 respondents.Respondent characteristics were divided into ten criteria.1.
