Abstract

AbstractThis research aims to determine the range of parameter value and to select the appropriate method for baseflow separation. Seven (7) recursive-digital-filters (RDF) and two (2) graphical methods were used for this study. Discharge data from 6 watersheds in the administrative area of UPT PSDA Pasuruan in East Java were used to test those nine (9) algorithms. Firstly, each method was calibrate using daily discharge data for each year (annually) to separate baseflow. Then, optimal parameter values are obtained by averaging the annual values. Calibration process produce optimal parameters value for each watershed. Furthermore, validation are effectued using optimal parameter values from Pekalen watershed’s to other watersheds. The result show that optimal parameter values from Pekalen could be used to separate baseflow in other watersheds. Results also recommend two algorithems (EWMA filter and fixed interval) to be used more frequently for baseflow seperation on this region.AbstrakPenelitian bertujuan untuk menentukan nilai range parameter dan memilih metode pemisahan yang dapat direkomendasikan untuk diterapkan pada DAS-DAS di wilayah provinsi Jawa Timur. Tujuh (7) metode berbasis filter atau Recursive-Digital-Filter (RDF) dan dua (2) jenis metode berbasis grafis digunakan dalam penelitian ini. Data debit harian (dari 1996 sd 2005) yang berasal dari 6 DAS pada wilayah UPT PSDA Pasuruan dipilih sebagai sampel pengujian. Kalibrasi dilakukan menggunakan data debit musimkemarau (bulan Juli - September) pada tiap tahun-nya dan diperoleh kisaran nilai parameter untuk tiap metode pada masing-masing DAS. Proses validasi dilakukan dengan menggunakan nilai parameter DAS Pekalen, untuk menentukan baseflow pada DAS lain. Hasil penelitian menunjukkan bahwa nilai parameter dari DAS Pekalen dapat digunakan untuk menentukan aliran dasar (baseflow) pada DAS lain. Penelitian juga merekomendasikan filter EWMA dan metode grafis interval tetap (fixed interval) untuk digunakan di wilayah UPT PSDA Pasuruan.

Abstract

Coffee pulp and water hyacinth are a biomass source that can be used to feeding material for biogas production as energy an anaerobic digester. But coffee pulp and water hyacinth contain lignin. The Alkaline or base hydrolysis is a method of the solving chemical structure of lignin compounds using a strong acid and base. The focus of research investigated the base hydrolysis with NaOH in coffee pulp and water hyacinth an anaerobic process for organic material reduction. The research design in laboratory conduct of organic materials reduction on coffee pulp and water hyacinth used Completely Random Design (CRD). Anaerobic treatments were without hydrolysis (H1), only the coffee pulp with hydrolysis (H2), only water hyacinth with hydrolysis (H3) and all with hydrolysis (H4). The highest NaOH concentration for lignin reduction on the base hydrolysis was 60 ppm. The analysis of variants with significantly (p<0.05) showed all treated differently. Anerobic treatment of the coffee pulp and water hyacinth (H4) had the highest value organic material reduction. The efficiency of organic material reduction i.e. C/N, BOD and COD was in sequence namely 64.22 ± 0.02; 75.23 ± 0.02 dan 52.55 ± 0.04.
