ABSTRACT

Keywords: Debit; Water

Needs ; Network Irrigation

Weir Third is one of the dams in Kuningan West Java. Dam Third,

located on Jl. New East Ring Road, Tonjong Hamlet, Sangkanmulya

Village, District Cigandamekar, Regency Kuningan. The distance

from the city of Brass is not enough, more than 13 km towards the

north and less than 24 km from Cirebon city to the south direction.

Dam Third irrigates an area of ± 1,010 Ha, covering two districts:

Regency Kuningan 348 Ha and Cirebon Regency 662 Ha. Buildings

are mainly third in the form of channel parent and channel

secondary. Research objectives This analyzes mark performance

based on condition damage, knowing performance moment this, get

weight component Channels and Buildings Weir Third. The author

uses primary data and secondary data. Primary data is obtained from

field observations, while secondary data is from UPTD SUP

Kalijaga – Cisanggarung. The methods used in the research Are

qualitative nature, descriptive – and inductive. Research results

show that the percentage performance component Channels and

Structures on Dams Third based on conditions and functions,

namely, Channel Primary and Secondary Weir Third with a

percentage condition good 15%, condition medium 50%, condition

damaged 34%, so the average condition channel Primary and

Secondary Weir Third in Moderately Damaged Condition. The

condition of the building on Dam Third is good at 7%, moderate

condition at 85%, and damaged at 9%, so Weir Third's average

condition is good. The result of the analysis calculation of rainfall

rain and comparison of discharge needs with the debit of irrigation

area availability shows that the debit availability river is bigger than

the debit requirement, with thus water needs in irrigation areas being

third in all-sufficient.

Introduction

Weir Third is a dam located in the Regency Kuningan, West Java. Based on

astronomical location, Dam Third is at coordinates 6°88'87.7” S and 108°50'78. 7” E.

Weir Third, located on Jl. New East Ring Road, Tonjong Hamlet, Sangkanmulya Village

, District Cigandamekar , Regency Kuningan . Distance from the city Kuningan is less

than 13 km towards the north and less than 24 km from Cirebon city to the South

direction. Dam Third's channel parent is Weir Third or DI Katiga. Dam Third is capable

of irrigating two sub-districts, Cigandamekar Regency Brass, with a total area of 348 Ha

Performance Analysis of Katiga Dam Irrigation Network Kuningan Regency

Jurnal Indonesia Sosial Teknologi, Vol. 5, No. 11, November 2024 5369

and Subdistrict Sedong Cirebon Regency, with a total area of 662 Ha, and Weir Third is

capable of irrigating the irrigation area with an amount of total of 1010 Ha (Purwanto &

Ikhsan, 2016; Sida & Mustari, 2018).

Referring to the problem, research This discusses performance network irrigation,

especially on Channel Parent, based on the building's aspect conditions and structural

functions. Some parts of the building, Channel Primary and Secondary, will be

investigated more physically and theoretically to produce criteria for Channel Primary

and Secondary (Khaerunisa, 2014; Muhammad Isla & Risti Puspita Sari Hunowu, 2022).

Research purposes This is to analyze the percentage performance channel Katiga

Bending Parent based on condition damage, analyze condition performance Channel

Secondary Weir Third based on evaluation conditions and functions building the

components, and obtain weight component Channel Primary and Secondary Weir The

third one that can be used as indicator performance Channel based on conditions and

functions its components (Alfian, 2010; Farida, 2016; Hrozencik et al., 2021).

Methods

Study location This is located in the Irrigation Area Weir. The third-most specified

is the Channel Parent Weir (Yuniati, 2021). The third one is in Tonjong Hamlet,

Sangkanmulya Village, Sub-district Cigandamekar, Regency Kuningan. The research

was conducted from May to July 2024. The research started with retrieving related data

from channel parent Weir Third in SUP (Service Unit) Kalijaga—Cisanggarung. Then,

the survey was conducted upstream of Channel Parent until the downstream Channel

Secondary Third.

Methods used in the research This method is qualitative, descriptive,

and inductive. Research of this nature is descriptive and intended. It can give a description

and explanation of the data and information obtained during the research, while the

approach is inductive based on thought processes, observations in the field, and empirical

facts.

Then, the upstream survey Channel Parent until the downstream Channel

Secondary Weir Third. Data collection is in the form of primary flats, results observation

directly in the field, and damage, type, and condition of physique channels and buildings.

Weir Third. Secondary data originate from agency-related sources.

Results and Discussion

1. Thiessen Polygon

Based on the River Basin Map, rainfall is the bulk data Rain Station Linggarjati,

Station Cigugur, and Station Ciawigebang. To obtain the area of each station's rainfall

rain and the entire station area's rainfall rain, then use one of the Thiessen polygon

methods as follows:

3. Analysis Debit Andalan

Before calculating the mainstay debit of 80%, namely estimate the large discharge

of flowing water, then sort the debits from the largest to the smallest (Mayasari et al.,

2012). To determine the 80% mainstay debit, here are the details of the debt that has been

sorted:

4. Evaporation Potential (Eto)

The quantities used in the calculation are the evaporation rate, transpiration rate,

and evapotranspiration rate with units of mm/day. The ETo value is used as a reference

to estimate plant water requirements and irrigation management and can be calculated as

follows:

Eto (mm/day) = c x Eto

= 1.10 x 4.55

= 5.01 mm/day

For other calculations, they can be presented in Table 4.

5. Water Requirements

Preparation of land For paddy starting in November

Location taken = 2 mm/day

Land preparation time (T) = 15 days

Saturation = 250 mm

Clean water needs in rice fields (NFR) for paddy can calculated :

NFR = ETc + P + WLR + Re

= 6.56 + 2 + 0 + 0.48

= 9.04 mm/ day

Clean water needs in rice fields (NFR) for secondary crops can calculated :

NFR = Etc – Re

= 3.28 – 0.34

= 2.94 mm/ day

After counting the NFR value of the pattern, the plant obtained NFR Max per year.

Next, determine irrigation water needs with the use of Efficiency total irrigation 0.65 and

its calculation like the following: (Setiadi & Muhaemin, 2018)

Irrigation water requirement = NFR / ( Efficiency x 8.64)

= 10.07 / (0.85 x 8.64)

= 1.37 l/sec/ha

Conclusion

The result of the analysis calculation of rainfall rain area using the Paddy-Paddy-

Secondary Crops, the comparison of the flow rate of water needed with the debit of

Irrigation Area Availability Third, can conclude that the debit availability river is bigger

from the debit requirement, with thus water needs in irrigation areas Weir Third all in all-

sufficient.

From the results analysis condition of the irrigation network, namely with a good

classification of 12%, moderate of 67%, and damage of 21%, it can be concluded that the

condition of the irrigation network in the Katiga Dam irrigation area is slightly damaged.

Then, for the number of management personnel available, only seven people, while the

actual need is 12 people, indicating a shortage of power managers, namely five people,

with a percentage of 42%, so that service to condition channel is not fulfilled enough.

The AKNOP analysis shows that operational and maintenance costs in 2025 will increase

from the previous year, so it can be said that budgeting for Operations and maintenance

in irrigation areas Weir Third is not good enough.
