Development of the irrigation district (DI) in Nabire district
began in 1972/1973 until 2014 the government carried out
6400 ha. The purpose of this study is to evaluate the
performance of the wells and networks of the irrigation areas
of the caliber. The results of this study show that the
performance of Nabire's wells and irrigation networks that
have been awakened is still low and requires attention with
an overall value of 64.74% consisting of the performance
value of the physical Prasarana 24.34%, plant productivity
of 9.86%, the supporting networks 3.33%, the Organization
of Personnel 9.18%, Documentation 2.74% and P3A/GP3A
/ IP3A 5.37% This indicates that the existing operating and
maintenance system is still very poorly by the Regulation of

Introduction
In the era of reform and regional autonomy, the problem that has been faced by the
government in carrying out food security improvement programs is the damage to
irrigation network infrastructure as a system that functions to supply water to agricultural
land in the regions (Permadi, Anwar, & Purnomo, 2019). In general, this damage is caused
by natural disasters and less optimal irrigation management of irrigation infrastructure
(Wanyama et al., 2017). The lack of optimal irrigation management is in the form of weak
operation and maintenance (OP) activities carried out by irrigation managers. Irrigation
network OPs, especially dam OPs, are always less prioritized than rehabilitation,
improvement, and new development activities (Putu Indah Dianti Putri, Suputra, &
Nuraga, 2022). To support the fulfillment of the community's water needs, and to support
national food security in the agricultural sector, the government has implemented various
programs, including the irrigation dam construction program and its facilities. The
irrigation dam construction program is intended to meet the needs of agricultural water

and water in existing communities and support the mission of strengthening rice self-
sufficiency is also directed to support the government's efforts to improve farmers'
welfare, create jobs, improve the quality of the environment, especially in rural areas and
alleviate poverty (Hamakonda, Taus, Lea, & Ludji, 2022).
As a result, the damage to irrigation infrastructure occurs little by little without
realizing it until the stage of heavy damage which causes the performance of the irrigation
system to decline. The government's problems in optimizing OP activities are caused by
the limited data on the condition of irrigation networks that are relevant to the current
conditions provided by irrigation managers, especially irrigation networks that have a
very large area. (Mulyandari, Handoyo, Mawandha, & Kesuma, 2022). Nabire Regency
is one of the rice field centers and the second largest after Merauke Regency in Papua
Province (Papua TPH Office, 2014; BPS Papua, 2015). From this district, West Nabire
District (Kampung Bumi Raya), Makimi District (Kampung Biha), and Wanggar District
(Kampung Bumi Mulia) were determined as the largest irrigated rice field centers and
those that carried out regular planting for at least the last two years. The development of
Irrigation Areas (DI) in Nabire Regency began with the entry of the transmigration
program in Girimulyo Village in 1972/1973, transmigration in Wonorejo in 1976/1978,
and transmigration in Kalibumi in 1980 with a rainfed rice field system. Meanwhile, the
development of new technical irrigation began with the construction of the Kalibumi Dam
which began in 1996, and the development of primary and secondary networks in
Kalibumi Kanan covering an area of 4,400 ha. Then in 2014, the Ministry of Public Works
and Public Housing through the Directorate General of Water Resources of the Papua
River Regional Center built the Kalibumi Kiri irrigation network which will serve 2,000
ha of agricultural land. (Setyawati, Zulkarnain, & Darmaputra, 2014).
However, the performance condition of the dam and irrigation network in Kalibumi
Kanan has not been able to serve all planned agricultural land. Therefore, the performance
assessment of the Dam and Irrigation Network must continue to be carried out to find out
the problems that cause the performance of the dam and irrigation network to decline so
that maintenance steps or actions can be taken to maintain the function of the dam and
irrigation network of the Kalibumi Irrigation Area. (Ramdhani, 2020).
Research related to the performance of dams and irrigation networks has been
carried out by previous researchers, namely:
Nurmala, Nurdiyanto, 2018. Analysis of bending performance of Soka Hilir,
Dukupuntang District, Cirebon Regency. The Soka Hilir Dam was built in 1925 and is
located in Sindangjawa Village, Dukupuntang District, Cirebon Regency. At the
beginning of the construction of this dam served an irrigation area of 461 Ha, but currently
only 258 Ha is irrigated by the dam. This is due to the mutation of the area that causes the
narrowing of the irrigation area. Factors that affect the irrigation system at the Soka Hilir
Dam include increased sedimentation in the river, as well as damage to facilities and
infrastructure that results in ineffective and efficient irrigation water management and a
lack of balance between available discharge and required discharge. (Puro, Mulyo, &
Balapadang, 2020).
Evaluation of the Performance of Dams and Irrigation Networks in the Kalibumi
Irrigation Area in Nabire Regency
Indonesian Journal of Social Technology, Vol. 5, No. 12, December 2024 5621
The purpose of this study is to analyze the condition and function of the irrigation
network, analyze the institutional personnel and human resources that manage, analyze
the hydrology of the river, available discharge and demand discharge, analyze planting
patterns, analyze O&P costs, and analyze the performance priorities of the Soka Hilir
Dam based on the AHP (Analytic Hierarchy Process) method. (Eka Wulandari Srihadi
Putri, Harisuseno, & Purwati, 2015).
The conclusion obtained from the results of the analysis is that the condition and
function of the Soka Hilir Dam irrigation area network are classified as moderate,
institutional personnel are only 3 people short of the required discharge, mainstay
discharge can meet the demand discharge, all alternative planting patterns can be fulfilled
by mainstay discharge, O&P costs have increased in 2017 and decreased in 2018, Priority
determination using the AHP method which is more than 5 prioritized is Maintenance
Costs for dams and irrigation areas with a weight of 56.55%.
The objectives of this research are:
1. Analyzing the performance of dams and irrigation networks in the Kalibumi irrigation
area of Nabire Regency
2. Analyze the appropriate Operation and Maintenance system based on the results of the
performance assessment of the dam and network carried out
3. Determine strategies and policies for improving the performance of the dam and
network.
Method
This research is located in the Kalibumi Irrigation Area. The Kalibumi Dam is
included in the area of Kampung Bumi Raya, Wanggar District, Nabire Regency.
Geographically, the Kalibumi Dam is located at 1350 25 E and 3024' – 30 28' LS, which
is southwest of the city of Nabire and can be reached by land by motorized vehicle for ±
30 minutes. The irrigation network used for research is the Kalibumi Kanan Irrigation
Network with a planned service area of 4,400 hectares. (Sugiyono, 2016).
The method that will be carried out in this study uses a descriptive research method
with a combination of qualitative and quantitative research methods (mixed methods).
The data taken are primary data and secondary data.
1. Primary data
The primary data collected is the result of measurement surveys and observations
in the field which contain information on the condition of dams and irrigation networks
as well as interviews with users and managers of dams and irrigation networks in
Kalibumi.
2. Secondary data
Secondary data are document data related to dams and irrigation networks in
Kalibumi (network scheme and building scheme) as well as other irrigation area identity
data related to dam management and irrigation networks such as water availability, raw
area, functional area, and potential area. Secondary data related to network schemes and
