"Daerah Aliran Sungai DAS Citarum merupakan DAS terbesar di Jawa Barat dan merupakan DAS yang menjadi sumber air minum bagi kawasan urban Bandung, Cimahi, Cianjur, Purwakarta, Bekasi, Karawang dan DKI Jakarta. DAS Citarum bagian hulu berfungsi sebagai daerah konservasi, oleh karena itu indeks kekritisan air di daerah ini perlu diperhatikan agar kebutuhan masyarakat di sepanjang sungai Citarum dapat terpenuhi. Namun, nilai pengamatan seperti indeks kekritisan air dan faktor-faktor yang mempengaruhinya, memuat informasi spasial, oleh karena itu seringkali terdapat keterkaitan spasial antar pengamatannya nilai dari suatu pengamatan di suatu lokasi memiliki keterkaitan dengan nilai dari pengamatan di lokasi sekitarnya sehingga jika dimodelkan dengan model regresi linier maka asumsi keacakan residual seringkali tidak terpenuhi. Salah satu solusinya yaitu dengan memodelkannya menggunakan model regresi spasial. Model regresi spasial merupakan model regresi yang memperhatikan unsur spasial lokasi koordinat data. Tujuan dari studi ini yaitu untuk memodelkan indeks kekritisan air di DAS Citarum hulu menggunakan Spatial Durbin Model SDM dan Spatial Durbin Error Model SDEM . Pengujian autokorelasi residual menggunakan uji Moran's I memberikan hasil bahwa terdapat autokorelasi spasial pada residual model regresi linier, variabel terikat indeks kekritisan air, dan juga pada variabel-variabel penjelas persentase luas hutan, luas kebun, luas perkebunan, dan kepadatan penduduk. Uji likelihood ratio menunjukkan bahwa model SDM dan SDEM lebih baik dari model regresi linier berganda dalam memprediksi indeks kekritisan air di DAS Citarum hulu. Berdasarkan nilai AIC dan R squared pada model SDM dan SDEM diperoleh kesimpulan bahwa model SDM lebih baik dibandingkan dengan model SDEM.

Citarum Watershed is the largest watershed in West Java and serves as the water supply for urban communities in Bandung, Cimahi, Cianjur, Purwakarta, Bekasi, Karawang and Jakarta. Upper Citarum watershed serves as a conservation area, therefore, water criticality index in this area should be noted so that the needs of the communities along the Citarum river can be met. However, the observed values such as the index criticality of water and the factors influencing it, contain spatial information, where an observation at a locations correlates to the observations around it so that the assumption of randomness of the linear regression rsquo s residuals are often not fulfilled. One of the alternative solution is using spatial regression models. Spatial regression model is a regression model that takes into account the element of spatial location coordinate of the data .

The purpose of this study is to model the critical index of water in the upper Citarum watershed using Spatial Durbin Model SDM and Spatial Durbin Error Model SDEM . Residual autocorrelation testing using Moran 39 s I test showed there is significant spatial autocorrelation in the residual of linear regression model, the dependent variable water criticality index, and also the explanatory variables population density, the percentage of forest area, gardens, and plantations. Likelihood ratio test showed that the SDM and SDEM are better than multiple linear regression model in predicting the water criticality index in the upper Citarum watershed. Based on the value of AIC and R2 of the SDM and SDEM models, the SDM model is better than SDEM."

The main objective of this research was to develop a model representing the resilience of the socio-hydrological system through polycentric water governance that integrates community resilience to ensure the sustainability of river ecosystem services in the Citarum River Basin. The method used in this study is a mathematical formula to calculate the vulnerability index using secondary data from various institutions managing the Citarum River Basin (CRB). The results of the vulnerability index calculations were used as the basis for determining the resilience of the CRB socio-hydrological system. Furthermore, statistical modeling of structural equation Modelling (SEM) using LISREL software version 8.7 is also used to assess community resilience. Community resilience was analyzed based on primary data from the results of measuring community social capital and the values, beliefs, norms, and pro-environmental behavior of individual community members in the Citarum River Basin. A conceptual model representing the resilience of the socio-hydrological system was built using system dynamics modeling with the VensimPLE software version 9.3.0. The results show that the vulnerability index (VI) in the Citarum River Basin is 1.80 in the upstream zone, indicating that the socio-hydrological system in this zone is moderately vulnerable. In the middle zone, the value of VI is 2.52 and in the downstream zone, it is 2.06, which indicates that the socio-hydrological system in the two zones is significantly vulnerable. This study concludes that to overcome the vulnerability of the socio-hydrological system in the Citarum River Basin, it is necessary to implement a model to increase the resilience of the socio-hydrological system through polycentric water governance interventions. Polycentric water governance supported by collective community action with the strength of social capital and pro-environmental behavior as a form of community resilience will achieve the sustainability of river ecosystem services in the Citarum River Basin.

"Rice fields located in Citarum Hilir watershed of Karawang district are more and more affected by growth of residential and industrial areas. This resulted in the need to have supporting rice fields elsewhere including in the upstream region. ln Citarum Hulu watershed, 19,5% fiom the existing rice fields is non-irrigated with 32,l9% of population work in the agriculture sector. But productivity of' non-irrigated rice fields of Citanim Hulu watershed is still low, which is below 25 kwintal/ha. One of the efforts to increase its productivity is to look at the local climate model. The low productivity may also be caused by factors such as slope and altitude, which are used as variables in Wilayah Tanah Usaha (WTU). Sandy (1985) wrote that growth and death of any plant in Indonesia depend on water. Awarding to Chang (1968) every process in a plant is affected by water. Furthermore, FAO believed that the growth requirement of a rice plant is also depended on water availability. Mohr, Schimdt-Ferguson, and Oldeman made climate classifications based on rainfall in relation with plant needs of irrigation. Spatial climate model and planting time/season are important factors in management of non-irrigated rice fields in Citarum Hulu watershed. These rice fields are nou-unifonnly found in the center down to the south. Rice production varies from 22 to 4l kw/ha where the majority produces 30-40 kw/ha. Productivity model for the northem part is varied, and to the south is more stable with productivity of 30-40 kw/ha. The annual average rainfall in Citarum Hulu watershed is 1770-3458 mm/yr where the majority of the region has in the range of 2000-3000 mm/yr. Maximum monthly rainfall is 558 mm and a minimum of 6 mm on average. Rainfall is high in the months of November to April and dry period is fiom June to August. Mol-rr?s climate classification is around class III - Vb where the majority is in class III-IV. Schmidt-Ferguson?s climate classification for this area is type C to type A, where the majority is in the wet type (A). 0Ideman?s climate classification varies from D3 to Bl where the majority ofthe region is in climate group C-B (humid-wet). ln general, climate model for Citarum Hulu watershed is as follows: in the center (around the city of Bandung) is almost always drier than its surrounding areas, specifically in the northem and southem parts that are mountainous. The distribution of non-irrigated rice fields has a strong correlation with the annual rainfall model of Schimdt-Ferguson and Oldeman, because as an area has more precipitation there tend to be non-irrigated rice fields. But it is not true with Mohr climate. A strong correlation in productivity of non-irrigated rice fields with rainfall model, Mohr, Schmidt-Ferguson, and Oldeman climate models mean that as a region receives more precipitation then 'there is a tendency of higher rice productivity. But there is also a tendency that if an area is extremely wet, the productivity will decrease. Planting season in the Citarum Hulu watershed is from October and May with 4 planting time models: October/February, October/March, November/March, and December/April. In the November/March, planting time is dominant in almost all of the watershed area. Part of the non-irrigated rice fields in Citarum Hulu watershed are still according to the WTU conception, that is 65,87%, which the majority is in the center. As for the rest of this region, they should be converted into protected forest areas (especially in the south) and hard plant agriculture (in the cast). Keywords: DAS Citarum Hulu, non-irrigated rice fields, rainfall, climate model, Mohr, Schmidt-Ferguson, Oldeman, WTU conception, planting time."
