AbstractIn 1885, the Dutch East Indian state began a huge ‘civilisation offensive’ in the field of irrigation focussed on Java. It comprised creating modern irrigation works, regulating irrigation management and planning construction activities. This paper shows the successes and failures of this irrigation programme, which was part of the Dutch ‘colonial project’ as a whole. Particular attention is given to the question of why the colonial state made irrigation affairs one of its special missions. What emerges is that Dutch exploitation interests (sugar) were dominant, though the welfare interests of the native population (rice) clearly became more prominent. Another question to be dealt with is the issue of how the Dutch East Indian state realized its plans. As this paper argues, the engineers of the Public Works Department played a key part, but only in competition and cooperation with other relevant groups.

AbstrakKolonisatie adalah program perpindahan penduduk versi pemerintah Hindia Belanda pada awal abad XX. Program migrasi ini awalnya diberi nama Kolonisatieproof dan dijalankan sesuai dengan tuntutan Politik Etis bersama dengan program edukasi dan irigasi. Meski kelihatannya sebagai program yang peduli terhadap perbaikan kondisi masyarakat pribumi, tetapi sejatinya ketiga program tersebut dilaksanakan untuk kepentingan kolonialisme di Hindia Belanda yang telah sekian lama meraup keuntungan sejak masa VOC dan Hindia Belanda. Pada masa pemerintahan militer Jepang juga dilakukan perpindahan penduduk yang disebut kokuminggakari khusus di wilayah Lampung. Penduduk yang dipindahkan ini adalah para rômusha dari Pulau Jawa. Setelah kemerdekaan Republik Indonesia, program perpindahan penduduk ini dilanjutkan dan disebut transmigrasi. Tidak jauh berbeda dengan kolonisasi, sasaran perpindahan penduduk ini adalah dari daerah-daerah yang dianggap padat penduduknya terutama Pulau Jawa ke daerah lain di Indonesia. Khusus Lampung, pelaksanaan perpindahan penduduk ini sangat bernilai karena daerah ini menjadi pionir proyek di tiga masa pemerintahan. Tujuan penulisan ini adalah untuk mendeskripsikan tiga peristiwa perpindahan penduduk tersebut disertai perbandingan di antara ketiganya. Penulisan ini menggunakan teknik pengumpulan sumber melalui studi kepustakaan dan mengenai dampak yang ditimbulkan dianalisis menggunakan teori integrasi. Abstract In the early twentieth century, the Nederland-Indie government introduced a program Kolonisatie. At the beginning of its implementation, that program was know as Kolonisatieproof. The program is run in accordance with the Ethical Policy along with educational and irrigation program. Although it seems as programs that concerned to the improvement of indigenous peoples, but is actually that programs were implemented for the benefit of the Dutch East Indies's colonialism. In the reign of the Japanese military, migration program also conducted by goverment which known as kokuminggakari, especially in Lampung. The Population which displacement in kokuminggakari's program is the romushas of Java. After the independence of the Republic of Indonesia, this program continued and know as migration and transmigration. In the era of Indonesian independence, the government carried out the similar program with the colonization program. The purpose of this program is to moved the population from the densely region, especially in Java, to moved to other region in Indonesia. In Lampung, the implementation of this migration is very important because the area has become a pioneer project in three periods. The purpose of this research was to describe the migration of three events with a comparison between the three events. This study uses the source collection techniques through the study of literature and the data were analyzed using the theory of integration.

Project is picture of interaction model from various interests in social communication among the stakeholders. Stakeholders interaction factors can be influenced by domination and competencies beside their interpersonal skills. This research based on samples of respondents from East Java and West Sumatra provinces, Indonesia, which have similar social behavior and socio-cultural strength. Subject of research focused on three main project’s stakeholders, which will be analyzed by partial least square-structural equation model (PLS-SEM). The result of analysis shows that domination factor has the greatest influence to infrastructures project implementation. It means that influence of feudalism cultural heritage remain affecting to local people character and work culture. However, respondents from East Java consider competency as a significant variable which influences the infrastructure project success. West Sumatera respondents are the opposite, where competency is not a significant variable to the project success directly. Meanwhile, interpersonal skill can be good mediation variable for domination and competency to the project success in the West Sumatra, but it is not good enough to mediate domination to project success in the East Java. Thus, it can be concluded that West Sumatra respondents have a more feudal interaction style than stakeholders in East Java.

An Irrigated Area is a unit of land that gets water from an irrigation network. Irrigation Networks are channels, buildings, and their complementary buildings that are a single entity necessary for the provision, division, administration, use and disposal of irrigation. The Range Irrigation Area is located in the lowlands of the lower reaches of the Cimanuk river in the northern part of Majalengka Regency from West Java Province. Irrigation Modernization This range is carried out because the irrigation system has not been modernized for decades, causing the performance of water services to be less than optimal. The use of materials for construction that is in the ground or groundwater level, namely by using Corrugated Concrete Sheet Pile (CCSP), Corrugated Concrete Sheet Pile (CCSP) is a concrete used for foundation structures or irrigation canals that function as soil retaining walls. Corrugated Concrete Sheet Pile (CCSP) is one of the products owned by a well-known concrete company, namely WIKA concrete. The type of CCSP used in this project is CCSP W325 B with a length of 9 meters.

In the process of implementing a project, few people find projects that go according to plan. In general, there are projects that are behind schedule, both in terms of time and schedule, but there are also projects that experience acceleration from the originally planned schedule. Project delay is a problem that arises as a result of unplanned construction implementation. Damage to the state due to additional costs and delays is one of the impacts of project delays. The purpose of this research is to track project implementation, identify factors that cause delays, calculate the cost of delays that occur, find root causes and suggest alternative solutions that can be used to anticipate project delays. Monitoring and evaluating delays require an approach that includes the use of Microsoft Project Tracking, Fishbone Charts, and Root Cause Analysis. Alternative methods are used to track performance and analyze delays in public service building projects. The results showed a lack of understanding of human resources in terms of planning/evaluating existing plans, lack of training programs related to the field of work being handled, and poor schedule planning causing a lack of lightning rods, installation in the main building, lighting in changing rooms, grounding systems, central duct/airline, less power cables than needed and original water source using PAM water converted into deep pumping wells.

The number of World Irrigation Heritage Sites (WHIS), selected by the International Commission on Irrigation and Drainage (ICID), have reached 140 as of 2023, and 83 of them are located in Asia, China, Japan and Korea, which accounts for more than 65% of the total1. This shows that the value of the Eastern Irrigation Project is being recognized worldwide. As an irrigation project, the engineering technology used and the effect of irrigation on the people are one of the most concerned topics, but the spiritual value behind the project are less explored. This paper is based on the investigation and comparison of varied Oriental irrigation heritages of China, Japan and Korea in the register, extracting the common Oriental water control culture of the three countries, and proposing the use of such a culture to help the collaboration around heritage protection in East Asia.

Mayang Watersheds frequently hit by floods during the rainy season and drought during the dry season. This study aims to assess the water balance by calculating water resource availability and water demand in the Mayang watershed. The Water Evaluation and Planning (WEAP) model was used as the primary tool for the analysis. The supply of water comes only from precipitation. Demand was calculated based on the water demand for irrigation, domestic, urban, industrial, and livestock uses. The unit of time to calculate the water balance is ten days. It means that each month is divided into three-time steps. Analysis of the WEAP is based on the water demand from 2002 to 2019. The results showed that from 3rd December to 1st May, the Mayang river and its tributaries could supply all demand sites up to 100%. However, unmet demand occurs from 2nd May to 2nd December. The highest first unmet demand occurred in October, with 0.67 million m3. The management of water resources, especially in terms of distribution during the rainy season and dry season, must be considered.

<p class="teksabst"><strong>Abstract.</strong><em> </em>Sugarcane (<em>Saccharum officinarum</em> L.) growth and production are greatly affected by water availability. The lack of water availability in sugarcane cultivation can be surmounted by irrigation. In performing irrigation, it is essential to understand the sugarcane crop water requirement and soil texture as they influence the irrigation efficiency. To date, drip irrigation is considered as the most efficient type of irrigation. This study aimed to investigate both agronomic performance and economic benefits of different irrigation methods for sugarcane grown in sandy (in Kediri) and clay (in Pasuruan) soils. The irrigation treatments were surface drip irrigation, sub-surface drip irrigation, and conventional irrigation, while the conventional irrigation through drains was the control treatment. The experimental design was a Randomized Complete Block Design with three replications. In sandy soil, both surface and sub-surface drip irrigation led to better agronomical performance yet the conventional irrigation showed a contrasting result. Sugarcane productivity under surface drip irrigation, sub-surface drip irrigation, and conventional irrigation were 81.29, 110.33, and 69.25 tons ha<sup>-1</sup>, respectively. Meanwhile, in clay soil, there were no prominent differences of agronomic parameters between all irrigation treatments. Sugarcane productivity under surface drip irrigation, sub-surface drip irrigation, and conventional irrigation were 79.03, 60.58, and 78.16 tons ha<sup>-1</sup>,respectively. The water cost used to produce one kg of sugarcane biomass under conventional irrigation, surface drip irrigation, and sub-surface drip irrigation in sandy soil were IDR 169, IDR 103, and IDR 87, while the cost in clay soil were IDR 443, IDR 218, and IDR 293, respectively.<strong></strong></p><strong><em>Abstrak</em>. </strong>Pertumbuhan dan produksi tebu (<em>Saccharum officinarum</em> L.) dipengaruhi oleh ketersediaan air. Kekurangan air dalam budidaya tebu dapat dipenuhi melalui irigasi. Dalam melakukan irigasi, penting untuk mengetahui kebutuhan air tebu dan tekstur tanah karena kedua faktor tersebut mempengaruhi efisiensi irigasi. Hingga saat ini, irigasi tetes merupakan salah satu jenis irigasi yang paling efisien dalam pertanian. Studi ini bertujuan untuk mengetahui performa agronomis serta keuntungan ekonomis berbagai metode irigasi pada tanaman tebu yang ditanam di tanah bertekstur pasir (di Kediri) dan lempung (di Pasuruan). Perlakuan irigasi pada penelitian ini yaitu irigasi tetes permukaan, irigasi tetes bawah permukaan, dan irigasi konvensional, dimana irigasi konvensional yang diberikan melalui parit menjadi perlakuan kontrol. Desain percobaan menggunakan Rancangan Acak Kelompok Lengkap, dengan tiga ulangan. Pada tanah pasir, performa agronomis tebu pada perlakuan irigasi tetes permukaan dan bawah permukaan lebih baik daripada irigasi konvensional. Produktivitas tebu pada irigasi tetes permukaan, irigasi tetes bawah permukaan, dan konvensional di tanah pasir masing-masing sebesar 81,29 ton ha<sup>-1</sup>, 110,33 ton ha<sup>-1</sup> dan 69,25 ton ha<sup>-1</sup>. Pada lokasi percobaan di tanah lempung, tidak ada perbedaan agronomis tebu yang signifikan antar perlakuan irigasi. Produktivitas tebu pada irigasi tetes permukaan, irigasi tetes bawah permukaan, dan konvensional di tanah lempung masing-masing sebesar 79,03 ton ha<sup>-1</sup>, 60,58 ton ha<sup>-1</sup>, dan 78,16 ton ha<sup>-1</sup>. Biaya air yang digunakan untuk memproduksi satu kilogram tebu dengan perlakuan irigasi konvensional, irigasi tetes permukaan, dan irigasi tetes bawah permukaan di tanah pasir masing-masing sebesar IDR 169, IDR 103, dan IDR 87, sedangkan di tanah lempung masing-masing sebesar IDR 443, IDR 218, dan IDR 293.

In the 19th century, in regions that lay outside the agriculture lands along the shores of rivers in the Middle East, dry agriculture that was affiliated with seasonal precipitation was practiced. This situation meant that many productive lands were not farmed. The spread of agriculture production without being dependent on precipitation and an increase in production was only possible with a wide-ranging irrigation project. This paper takes as its basis the Middle East, which was limited in water resources and examines the irrigation projects that were developed for irrigated agriculture and gardening in Jaffa, a seaside Palestinian city; in addition, the concessions that were granted in this context will be examined. If we take into account that the conflicts affiliated with water sources in this region still continue today, the development of an irrigation project in a city like Jaffa, both from the aspect of the direction of state agricultural policies and for evaluating the settlement policies of the Jewish colonies, is extremely important.

Climate change intensifies hydroclimate variability, leading to more frequent and severe drought, which pose significant challenges to water, food, and energy security. Droughts are complex natural hazards that area difficult to predict spatially and temporally. East Java, with its historically extreme droughts and reliance on agriculture, exemplifies these challenges. This study investigates the definition, measurement, driving mechanisms, and historical and future projections of drought occurrences in the region. Notably, a strong correlation is observed between El Niño and drought events, predominantly impacting the northern areas that heavily depend on rice irrigation. East Java’s prolonged dry season and limited rainfall exacerbate the recurring threat of extreme drought. With global warming amplifying these patterns, urgent action is imperative. This paper highlights the need for a comprehensive understanding of drought dynamics to develop effective mitigation and adaptation strategies of agricultural activity. By examining the interplay between climate phenomena, rainfall patterns, and droughts impacts on agriculture, valuable insights are gained to foster sustainable water resource management and build resilience to drought in East Java.

The current challenges of industrial agriculture focus on environmental safety. Water quality is an indicator of environmental sustainability. The cultivation system has an impact on water quality. The aim of this study is to assess the water quality of agricultural systems. Anthropogenically, agricultural activities have an impact on environmental aspects. Identification of agricultural systems is clustered into organic and non-organic agriculture. The agricultural system in Indonesia is regulated based on SNI 6729;2016. Water sampling was carried out at three points, including upstream, middle (irrigation), and downstream (river). Water sampling at each point was repeated three times. Assessment of the physical quality of water using the Combo Quality Meter. Water samples for chemical and biological analysis at the Environmental Laboratory, Perum. Jasa Tirta 1. Determination of water quality standards refers to Government Regulation No. 82 of 2001. In the upstream section, pollution can be seen in the biological oxygen demand (BOD) indicator, with an average of 15.03 mg L-1 for organic and conventional systems. The phosphate indicator averaged 1.96 mg L-1. In the middle section (irrigation), the pollution indicators for BOD, phosphate, and total Coliform parameters were 6.76 mg L-1 for the organic system, 7.37 mg L-1 for the non-organic system, and 1,290 CFU mL-1. In the downstream (river), pollution indicators consist of total suspended solids (TSS), BOD, chemical oxygen demand (COD), and total Coliform. Anthropogenic identification for clustering agricultural systems at the research location uses stratified disproportional sampling. The results of this research provide recommendations for water quality management for sustainable agricultural environmental management.

Abstract East Java has a large amount of arid terrain with a dry environment that could potentially be used for maize cultivation. It hasn’t been managed well, with little irrigation that only depends on rainfall and poor soil fertility. It is possible to grow maize on dry terrain, but first it is important to consider whether socio-economic strategies are effective, affordable, and simple to use. Five land management approaches, including (a) water management, (b) nutrient management, (c) organic matter management, (d) soil amelioration and conservation, and (e) crop integration livestock or institutions, are required to address the major issues of restricted water and low soil fertility. Activities to develop dry climate dry land agriculture are carried out during the dry season (MK 1) 2019 in Kandang Village, Kapongan District, Regency Situbondo in an area of 20 hectares. These activities include research on superimposed planting systems, irrigation, and biocahar as well as display of maize varieties and fertilisation.

Abstract The development of Kediri City in various sectors, such as industry, agriculture, and population growth, also increases water. The utilization of groundwater is still a major mainstay in this area. The utilization of groundwater includes the construction of production wells for irrigation and raw water. The aquifer susceptibility should be considered during groundwater exploitation to minimize a negative impact on the environment. This research aims to analyze the susceptibility of the aquifer to pumping in Kediri City, which is helpful for planning and making decisions in the management of groundwater resources. The determination of aquifer susceptibility is based on aquifer response characteristics, aquifer storage characteristics, allowable subsidence of groundwater level, and depth to the groundwater table. Based on those parameters, it can be concluded that the aquifer susceptibility on groundwater utilization in Kediri City is at moderate and high levels. Areas with moderate aquifer susceptibility are located on the west side of Kediri City, and high aquifer susceptibility is in the middle to the eastern side of Kediri City.

The aim of this study is to evaluate the efficiency of East Java rice production in 2018. This study uses a model for measuring the efficiency of stochastic frontier analysis (SFA). Empirical results of these findings indicate that the efficiency of rice production in East Java in 2018 was said to be very efficient in several districts and towns affected by the variable dry milled grain / GKG and irrigation variables, although there are still some districts and towns that cannot be said to be productive. Additionally, the explanatory variable of population growth affects the technical inefficiency of East Java rice production in 2018. Based on the results of this study's review, the practical implications for the government must continue to work to increase the scale and impact of efficiency on rice production, particularly on adding irrigated land to rice commodities, so that rice production can increase to the maximum and domestic food needs can be satisfied. Since the population of Indonesia continues to rise significantly, and rice is in fact a staple food for the people of Indonesia, rice production needs to be increased to ensure national social security. For this reason, it is necessary for the government to pay more attention to policies regarding the use and addition of paddy fields in order to keep optimum domestic rice production.

The performance assessment of a small-scale irrigation project plays a vital role in evaluating its effectiveness and addressing potential shortcomings in achieving desired outcomes. This study aims to provide a comprehensive analysis of the Jato small-scale irrigation project, assessing its performance based on various criteria and indicators. The study evaluates the project's infrastructure maintenance and system efficiency. The designed command area of the scheme is seventy-five (75 ha) but the current irrigated area of the scheme is sixty (60ha) only. To achieve the objectives, primary and secondary data were collected. To gather both primary and secondary data, data-gathering techniques include surveys, interviews, field observations, and meteorological data. Before, during, and after an irrigation event, while farmers were carrying out their regular irrigation practices, several field characteristics were measured and/or observed. These data included the type of crop, irrigation water discharge in the canal, and field size. A survey concerning the availability of water was also carried out among farmers. CROPWAT 8.0 Software was used to organize the crop pattern of the study area along with other relevant data, including soil, climate, rain crop, and crop pattern. Water flow measurement results of the Jato small-scale irrigation scheme at the head, middle, and tail of the lined & unlined main canal were found to be 53.6l/s, 45.4 l/s, and 29.9l/s respectively. The average water flow measurement result of the scheme is 43l/s which reduced from required flow by 18.15l/s. From the analyses of the water balance indicators, the canal conveyance efficiency, canal conveyance loss, application efficiency, and overall efficiency were found to be 70%, 30%, 70%, and 50% respectively. The overall average main canal conveyance efficiency and water conveyance loss were below the recommended values. The studies have shown that the effective infrastructure, irrigation ratio, and water surface elevation ratio of the scheme were found to be 66.7%, 80%, and 66% respectively. However, there were certain areas for improvement identified, such as the need for better coordination among project stakeholders and enhanced maintenance practices to ensure the long-term functionality of irrigation infrastructure.

Purpose: This study aims to determine the factors influencing the successful implementation of quality improvement projects. Theoretical framework: This research will focus on finding critical success factors for quality improvement projects and prioritizing improvements to improve the performance and success of quality improvement project implementation. Design, Methodology and Approach: The research used Smart PLS-SEM and Importance Performance Analysis (IPA). Smart PLS-SEM was first used to determine critical success factors for Quality Improvement Projects (QIPs). Furthermore, IPA was used to determine the position of each factor based on its importance and achievements. Findings: The result showed all dimensions and indicators significantly affect the success of quality improvement projects. The dimension with the highest outer loading value is the quality performance measurement dimension. The next step is measured using the IPA method to determine the critical factors for project success. The results of the IPA analysis show that quality control and leadership are crucial factors in the success of quality improvement projects in the second quadrant. At the same time, the factor that prioritizes improvement is quality assurance (first quadrant). Research, Practical & Social implications: Research, Practical, and Social Implications: The research implies that quality control and leadership are critical success factors for quality improvement projects. Leadership plays an essential role in implementing quality improvement projects, and leadership commitment is an important key to the success of these projects. In addition, there is a requirement for support from leadership regarding resource allocation. This resource allocation includes labor, costs, information systems, machines, and tools. Another factor that is critical to the success of these projects is quality control. Implementation of quality control has a vital role during the quality improvement project process and after the project. With quality control, the product suits the specifications and standards and meets the targets and standards set.

Indonesia is one of the countries with high biodiversity of freshwater fishes. One freshwater fish with a wide distribution in Asia with high economic potency for ornamental fish is dwarf snakehead. However, research on genetic characterization of dwarf snakehead from Indonesia is very limited. Therefore, this research aimed to compare genetic characterization of the dwarf snakehead from rice field irrigation at Donomulyo Village (Malang, East Java) and from Keji River (Magelang, Central Java). This study used a PCR method with universal primers: 16Sar and 16Sbr. The data obtained in this study were then analyzed using DNASTAR, BLAST, Mesquite, MEGA, DnaSP, and NETWORK. The results revealed the genetic distance between dwarf snakehead from rice field irrigation at Donomulyo Village and from Keji River was 1.36%. The divergence of GC content, haplotype number, variables sites, haplotype diversity, and nucleotide diversity in both populations exist. The results of this study are expected to arrange 16S mitochondrial DNA Library of dwarf snakehead from Indonesia which is useful for a reference in the conservation and utilization and management of dwarf snakehead in their habitat.

The majority of tourism objects in East Java still rely on artificial and nature-based tourism. As a result, there is an impression that the potential in the society in art and culture has not been optimized for the tourism industry. This service was intended in the context of optimization through exploring the potential of art and culture to support the tourism industry in East Java. This service also aimed to produce mapping data on the potential of cultural arts in the context of creating a directory of arts and culture in Malang Raya. Malang Raya will be used as a pilot project before it can be developed throughout East Java. The data collection method was focused on field studies based on the study of the PPKD (Pokok Pikiran Kebudayaan Daerah) documents for each region, while focus group discussions (FGDs) and field observations were also conducted. The results of the community service program showed that the potential of Malang Raya culture and arts could be compiled online and included in the PPKD mapping document.

PROJECT-BASED STUDENTS WORKSHEET TO ENHANCE STUDENTS' PANCASILA PROFILE IN HYBRID LEARNINGThe COVID-19 pandemic has had a changing impact on various aspects of life. One of them is the aspect of education which so far tends to be carried out in a conventional classical manner, which must develop towards digitalization. Therefore, this article discusses community service with the aim of improving the skills of teachers in schools under the auspices of YPK East Java in making project-based worksheets with hybrid learning to strengthen the profile of Pancasila students. The method adopted is empowerment through training and mentoring for teachers in schools under the auspices of YPK East Java with three stages namely preparation, implementation and follow-up. Based on an analytical study, the results of community service activities showed a positive impact on improving the skills of teachers in schools under the auspices of YPK East Java in making project-based worksheets with hybrid learning. Thus, teachers in schools have skills in implementing learning that is able to support strengthening the profile of Pancasila students.Pandemi COVID-19 memberikan dampak perubahan pada berbagai aspek kehidupan. Salah satunya yaitu aspek pendidikan yang selama ini cenderung dilaksanakan secara klasikal konvensional harus berkembang ke arah digitalisasi. Oleh karena itu, artikel ini membahas tentang pengabdian masyarakat dengan tujuan meningkatkan keterampilan guru-guru di sekolah yang ada di bawah naungan YPK Jatim dalam pembuatan LKPD berbasis project dengan hybrid learning untuk penguatan profil pelajar Pancasila. Metode yang ditempuh yaitu pemberdayaan melalui pelatihan dan pendampingan pada guru-guru di sekolah yang ada di bawah naungan YPK Jatim dengan tiga tahapan yaitu persiapan, pelaksanaan, dan tindak lanjut. Berdasarkan kajian analisis, hasil kegiatan pengabdian kepada masyarakat menunjukkan dampak positif pada peningkatan keterampilan guru di sekolah yang ada dibawah naungan YPK Jatim dalam membuat LKPD berbasis project dengan hybrid learning.

Desmanthus virgatus (L.) Willd. is an alien plant from Tropical America and reported present in Dutch East Indies in 1855. Nonetheless, the existence of its wild population is yet to be known, which caused by lack of record in Flora of Java vol. I. Hence the research conducted to report the existence of Desmanthus virgatus in Java. The research also conducted as a part of Alien Flora of Java compilation project. Field observation conducted in West Java (Bekasi, Bogor, Sumedang) and Central Java (Batang) by using the explorative method. Observation results showed the existence of Desmanthus virgatus wild population in Bekasi, Sumedang, and Batang. Therefore, the species can be stated as a new record of alien species for Flora of Java. Desmanthus virgatus presumably already escaped from cultivation and able to form its wild population in the nature.

Riparian vegetation habitats in irrigation canals provide various ecosystem regulatory services for human life, one of them was providing natural enemies for agricultural pests. This study aims to analyze the abundance of natural enemies at the paddy field, then to figure out the interaction between the riparian vegetation and natural enemies based on four different locations of tertiary irrigation canals at Slamet Village. Arthropods were observed by visual control and yellow pan trap methods. Whereas, riparian vegetation sampling points were determined by purposive sampling. The measured riparian vegetation and natural enemies were described by the important value index (INP), abundance, Shannon-Wiener diversity index (H'), evenness (E), dominance index (Id), and taxa richness (TR). The interaction between the riparian vegetation and natural enemies was analyzed by the PAST 3.20 program. The results showed that the first location of irrigation canals had the highest Shannon-Wiener Index value, taxa richness, evenness, and the lowest dominance value of riparian vegetation with respectively 4.97; 37 species; 0.93; and 0.02. Moreover, it was following with the highest value of natural enemies taxa richness (16 species), total abundance (4450 individuals), H' index (2.37), evenness (0.59), and low dominance index (0.27). Arthropods that act as natural enemies that were commonly found in this location came from the Formicidae, Coenagrionidae, and Coccinelidae families, while the most common pests found are from the Acrididae families. The opposite of that, the fourth location had the highest value of dominance index of riparian vegetation and pest arthropods (0.15; 0.84), H’ index of pest (2.31), taxa richness of pest (0.77), and the total abundance of pest arthropod (942 individuals). Pests that inhabit this location came from the Acrididae, Drosophilidae, Tephritidae, and Aphididae families
