The estimation of baseflow is a crucial task for water resources management. This research aimed to calibrate, validate, and evaluate the performance of the digital graphical method to separate baseflow. Two outlets of Brantas watersheds located at Kertosono (±6414,2 km2) and Ploso (± 8844,2 km2) were used for this study. This study used three digital graphics filters known as a local-minimum, fixed-interval and sliding-interval. The methodology consists of (1) data inventory, (2) data processing, (3) calibration, (4) validation, and (5) evaluating of models performance. Daily discharge data were separated into two periods, from 1996 to 2005 for the calibration and from 2006 to 2015 for the validation. Firstly, each method was tested annually by entering parameter values through trial and error. The period from July to September is considered as the peak of dry seasons and used to calibrate. The optimal values of parameters for calibration obtained by Averaging yearly values. Secondly, the optimal values from calibration are then used to test the model during the validation. Furthermore, statistical analysis was used to compare model performance during calibration and validation. Results show that the three methods could be used and perform well; however, the best performance is a local-minimum method.Keywords: Baseflow, separation, graphical-method, digital-filter, Brantas

Precision Agriculture has been a significant issue since the middle of the 1980s. Evapotranspiration is one of the main parameters in precision agriculture to analyze real water needs in the agriculture area and managing water resources. Traditionally evapotranspiration estimates by directly measured methods, i.e., lysimeter, pan-evaporation, eddy covariance, Bowen ratio, soil water, and climate data analysis. These methods are expensive techniques with low spatial representativeness. The utilization of remote sensing technology is expected to be an alternative solution for providing evapotranspiration data with a cost-effective and high spatial representative. This research aims to evaluate the MODIS global evapotranspiration as satellite-based evapotranspiration in estimating evapotranspiration in West Papua. Four (4) statistical parameters, i.e., mean error (ME), root means square error (RMSE), relative bias (RB), and mean bias factor (MBF), are using for evaluation. The research showed that MODIS global evapotranspiration was overestimated in estimating evapotranspiration in West Papua. However, MODIS global evapotranspiration has an acceptable accuracy in estimating evapotranspiration in West Papua indicated by ME = 0.66 mm/day, RMSE = 0.94 mm/day, RB = 0.27, and MBF = 0.81. Therefore, MODIS global evapotranspiration can be used as an alternative solution for providing evapotranspiration data in West Papua with a cost-effective.

The Effect of Altitude on Productivity and Quality of Bean Seeds (Phaseolus vulgaris L). The bean plant (Phaseolus vulgaris L.) is an annual horticultural crop with high economic value. In 2017, East Java experienced a decline in production of 3.80%. The tendency to decline was due to the quality of the seeds. This study was aimedto determine the productivity and quality of the bean seeds coded BU010 at different altitudes and to determine the relationship between height and productivity and quality. The research was conducted at three altitudes, namely Pucanganom Village (395 masl), Tlogosari Village (590 masl), and Sumberwringin Village (740 masl) in Bondowoso Regency. The study used a field experiment that was not randomized and the factors under study were altitude. Five sample points were taken in each location so that there were 15 data. The data obtained were analyzed using ANOVA and continued with correlation analysis with the independent variable in the form of altitude. The results showed that the difference in altitude gave a difference to productivity, namely the variable weight per m2. The height of the place gave a difference in the quality of the seeds, namely the variable weight of 100 seeds, vigor, and viability of the seeds produced. An altitude of 590 masl can be recommended for the development of the bean coded BU010 with the highest productivity which wasdescribed by the weight per m2, namely 7.91 ton ha-1. Seed quality at an altitude of 590 masl hadthe heaviest weight of 100 seeds, 96% viability, 98% seed viability. The relationship between altitude and productivity and seed quality factors was very low to moderate. The correlation value ranged from 0.12 to 0.44. Meanwhile, the relationship between altitude and total N content, rainfall, and temperature was very strong. Altitude had no significant effect on seed productivity and quality, and the weight of 100 seeds had a moderate positive correlation value of 0.4.The results of this study can be used as recommendations for farmers in the cultivation of bean coded BU010.The recommended altitude for the cultivation of beans code BU010 is 590 masl.

Pada 2017 di Jawa Timur terjadi penurunan produksi sebesar 3,80%. Kecenderungan penurunan disebabkan kualitas benih. Penelitian ini bertujuan mengetahui produktivitas dan kualitas benih buncis kode BU010 pada berbagai ketinggian tempat yang berbeda serta mengetahui hubungan antara ketinggian terhadap produktivitas dan kualitas. Penelitian dilakukan di tiga ketinggian tempat, yaitu Desa Pucanganom (395 mdpl), Desa Tlogosari (590 mdpl) dan Desa Sumberwringin (740 mdpl) di Kabupaten Bondowoso. Penelitian menggunakan percobaan lapang tanpa pengacakan dan faktor yang diteliti adalah ketinggian tempat. Sebanyak lima titik sampel diambil di masing-masing lokasi, sehingga diperoleh 15 data. Data tersebut kemudian dianalisis menggunakan analisis sidik ragam (ANOVA) dan analisis korelasi dengan variable bebas berupa ketinggian tempat. Hasil penelitian menunjukkan bahwa perbedaan ketinggian tempat memberikan perbedaan terhadap produktivitas yaitu pada variable bobot per m2. Ketinggian tempat memberikan perbedaan pada kualitas benih yaitu pada variabel bobot 100 benih, vigor dan viabilitas benih yang dihasilkan. Ketinggian 590 mdpl dapat direkomendasikan untuk pengembangan buncis kode BU010 dengan produktivitas tertinggi yang digambarkan oleh bobot per m2 yaitu 7,91 ton ha-1. Kualitas benih pada ketinggian 590 mdpl memiliki bobot 100 benih paling berat, vigor 96%, dan viabilitas benih 98%. Hubungan antara ketinggian tempat dengan faktor produktivitas dan kualitas benih sangat rendah hingga sedang. Nilai korelasi berkisar 0,12 - 0,44. Sementara hubungan antara variable ketinggian tempat terhadap kadar N-total, curah hujan, dan suhu adalah sangat kuat. Ketinggian tempat tidak berpengaruh nyata terhadap produktivitas dan kualitas benih, hanya saja bobot 100 benih memiliki nilai korelasi positif sedang yaitu 0,4. Hasil penelitian ini dapat dijadikan rekomendasi bagi petani dalam budidaya buncis kode BU010. Rekomendasi ketinggian tempat untuk budidaya buncis kode BU010 yaitu pada ketinggian 590 mdpl.

DAS bajulmati merupakan DAS kecil (± 173.4 km2) yang berada di wilayah timur pulau Jawa. DAS bajulmati memiliki iklim yang spesifik yaitu relatif kering dengan musim kemarau yang panjang (8-9 bulan selama setahun). Meskipun kondisi iklim yang kurang mendukung, sebagian besar masyarakat bekerja sebagai petani landang. Adanya perluasan lahan pertanian non irigasi/ladang mengakibatkan tutupan vegetasi semakin berkurang. Oleh karena itu, evaluasi DAS bajulmati diperlukan untuk mengetahui dampak perluasan lahan pertanian terhadap laju aliran dan sedimentasi dengan kondisi iklim yang cukup spesifik (kering). Salah satu model evaluasi pengelolaan DAS terhadap perubahan lahan adalah model SWAT (Soil and Water Assessment Tool). SWAT dapat menggambarkan proses hidrologi (erosi dan sedimentasi) unit lahan. data DEM resolusi (10x10 m) sebagai masukan utama untuk proses delinasi DAS. Data tanah, tutupan lahan, dan kontur digunakan untuk menentukan unit lahan/hydrolocal response unit (HRU) DAS. Data curah hujan dan iklim (suhu, kelembaban rata-rata, intensitas matahari, kecepatan angin) diperoleh dari stasiun yang tersebar di wilayah DAS. Semua data diintegrasikan ke dalam SWAT untuk menghitung proses hidrologi, erosi dan sedimentasi. Debit yang diamati digunakan untuk mengkalibrasi keluaran debit hasil SWAT di outlet DAS. Hasil kalibrasi debit menunjukkan nilai Nash-Sutcliffe Efficiency sebesar 0,53 dan validasi sebesar 0,5 serta koefisien determinasi sebesar 0,58 dan 0,78 (memuaskan) dan model dapat digunakan untuk ilustrasi proses hidrologi dalam DAS bajulmati. Analisis tingkat erosi SWAT menunjukkan bahwa 34,46; 39,19; dan 17,83 menunjukkan tingkat erosi sangat ringan sampai kategori sedang. Oleh karena itu, DAS Bajulmati masih dalam kategori aman karena rata-rata erosi berat dan sangat berat dibawah 10%. Nilai sedimentasi tertinggi pada HRU 512 dan SubDAS 23. Wilayah tersebut merupakan wilayah perkebunan dengan tingkat kemiringan diatas 40%.
