Abstract

ABSTRACTBedadung stream, located at Rambipuji, Balung, Wuluhan, and Puger, is downstream where dilution of organic wastes occurred and affects its water quality. Microorganisms decompose organic wastes and lead to depletion of dissolved oxygen in the water. The aim of this research was to analyze the deoxygenation rate of Bedadung downstream. The raw data was obtained by measuring stream flows and its water quality parameters (Temperature, DO and BOD) at 5 observed stations. The laboratory analysis consisted of BOD5 and long-term BOD2,4,6,8,10. Increasing the value of BOD for 10 days had a tendency of polynomial pattern order 3 with a coefficient of determination R 0.8987 – 0.9781. The 10 days BOD reactions were used to determine deoxygenation constant K (using least square method) with the result of ranged value 0.043 – 0.372 /day and Ultimate BOD 1.487 – 8.683mg/L. The values of deoxygenation rate at 5 stations were 0.182, 7.997, 7.236, 2.192, and 1.083 mg/L.day. The deoxygenation values were had a similar tendency with the amount of organic waste in the water column and its reduction rate due to the decomposition process.Keywords: Bedadung, BOD, Deoxygenation Rate, DOABSTRAKSungai Bedadung yang terletak di Kecamatan Rambipuji, Balung, Wuluhan dan Puger, merupakan sungai bagian hilir dimana zat pencemar organik bercampur, sehingga mempengaruhi kualitas perairan. Pencemar organik tersebut didekomposisi oleh mikroorganisme perairan sehingga menurunkan DO perairan. Tujuan penelitian ini adalah untuk mengkaji deoksigenasi Sungai Bedadung hilir. Data primer diperoleh dari pegukuran debit dan kualitas air (Temperatur, DO, dan BOD) di 5 (lima) titik pantau. Pengamatan BOD5 dan BOD2,4,6,8,10 dilakukan secara laboratorium. Peluruhan nilai BOD selama 10 hari cenderung memiliki tren polinomial dengan koefisien determinan berada pada nilai 0,8987 – 0,9781. Nilai peluruhan digunakan untuk menentukan nilai K (menggunakan metode least square) dan BOD ultimat. Nilai K di lima titik pantau menunjukkan rentang nilai 0,043 – 0,372 /hari dan BOD ultimat 1,487 – 8,683 mg/L. Sedangkan laju deoksigenasi di lima titik pantau menunjukkan nilai berturut-turut 0,182; 7,997; 7,236; 2,192; dan 1,083 mg/L./hari. Besar nilai deoksigenasi sangat ditentukan oleh banyaknya kandungan pencemar organik dalam air dan kecepatan reaksinya saat proses dekomposisi.Kata Kunci: Bedadung, BOD, Laju Deoksigenasi, DO

Abstract

ABSTRACT Agricultural waste is an organic material source. The organic matter was processed as compost. Compost block was one of composting technology developments. It has functioned as a planting medium. The type and size of raw materials are essential in the composting process. The purpose of this study was to examine variations in types and sizes of organic materials for compost blocks on the composting process and as a growth medium for chili plants. This study used a completely random design with two variables. The first variable was the variation of raw material type, i.e., coffee husk and pulp, tobacco petiole, and rice husk. The second variable was the variation of raw material size, i.e., 10, 40, and 80 mesh. The research data were analyzed using the analysis of variance test conducted with the Duncan test. The research data test show that compost from rice husks had the most C/N value of 19.71. The raw material on optimally composting refers to temperature and humidity parameters as rice husk. The most effective compost block as a planting medium is a rice husk with the size of 40 mesh. The variance analysis result showed the rice husk treatment with the size material of 0.06 cm had significant differences in the three parameters of vegetative growth of plants, i.e., plant growth rate, leaf growth rate, and leaf area. Keyword: composting, coffee husk and pulp,tabbaco petiole, rice husk, organic matter   ABSTRAK Limbah pertanian merupakan salah satu sumber bahan organik. Bahan organik tersebut berpotensi digunakan sebagai kompos. Kompos blok merupakan salah satu pengembangan teknologi pengomposan. Kompos ini digunakan sebagai media tanam. Jenis dan ukuran bahan baku berperan penting pada proses pengomposan. Tujuan dari penelitian ini adalah mengkaji variasi jenis dan ukuran pada bahan-bahan organik untuk kompos blok terhadap proses pengomposan dan sebagai media pertumbuhan tanaman cabai. Penelitian ini menggunakan rancang acak lengkap dengan dua variabel. Variabel pertama adalah jenis bahan baku kompos meliputi kulit kopi, limbah tangkai daun tembakau, dan sekam padi. Variabel kedua adalah variasi ukuran dengan menggunakan ayakan 10, 40, dan 80 mesh. Data hasil pengukuran dianalisis menggunakan uji Analysis of Variance yang dilanjutkan dengan uji Duncan. Hasil pengujian unsur hara menunjukkan bahwa kompos dari sekam padi memiliki nilai C/N sebesar 19,71. Pengomposan bahan yang berjalan optimal berdasarkan parameter suhu dan kelembaban adalah sekam padi. Kompos blok yang paling efektif sebagai media tanam berdasarkan parameter laju jumlah daun adalah limbah sekam padi ukuran 40 mesh. Hasil uji Analysis of Variance menujukkan bahwa pelakuan ukuran sekam padi sebesar 0,06 cm memiliki perbedaan nyata terhadap tiga parameter pertumbuhan vegetatif tanaman, yaitu laju tinggi tanaman, laju jumlah daun, dan luas daun.
