Rifqi Hidayat, Arthanur and Prof. Dr. Ir. Sugeng Prijono, SU and Dr. Kurniawan Sigit Wicaksono, SP., M.Sc (2024) Pengaruh Penempatan Biochar pada Saluran Drainase untuk Perbaikan Kemasaman Air di Lahan Rawa Pasang Surut Tipe Luapan B. Magister thesis, Universitas Brawijaya.
Abstract
Akumulasi unsur beracun hasil oksidasi pirit serta buruknya sistem drainase menyebabkan tingkat kemasaman tanah dan air sangat tinggi pada lahan rawa pasang surut tipe luapan B. Penempatan biochar pada saluran drainase dapat menjadi alternatif mengurangi tingkat kemasaman air di lahan. Tujuan dari penelitian ini adalah untuk (1) Mengevaluasi karakteristik jenis biochar yang ditempatkan pada saluran drainase untuk perbaikan kemasaman air di lahan rawa pasang surut tipe luapan B; (2) Mengevaluasi pengaruh penempatan biochar pada saluran drainase terhadap perbaikan kemasaman air di lahan rawa pasang surut tipe luapan B; dan (3) Mengevaluasi pengaruh jenis biochar terhadap perbaikan kemasaman air di lahan rawa pasang surut tipe luapan B. Penelitian dilaksanakan di Desa Belandean, Barito Kuala pada bulan Oktober 2023 - Maret 2024. Analisis sampel air dilaksanakan di Laboratorium Terpadu BSIP Lahan Rawa. Penelitian menggunakan Rancangan Acak Kelompok dengan 3 ulangan dan perlakuan terdiri dari biochar sekam padi dan biochar tongkol jagung yang ditempatkan pada saluran drainase. Variabel yang diamati yaitu karakteristik bahan baku biochar, kapasitas tukar kation biochar, pH, Al tersedia, Fe tersedia, dan SO 2- tersedia pada air. Data yang terkumpul selanjutnya dilakukan uji T, uji korelasi dan uji regresi. Hasil penelitian menunjukkan bahwa penempatan biochar pada saluran drainase mampu meningkatkan pH di dalam air, yang diikuti dengan penurunan kadar Al tersedia, Fe tersedia, SO 2- tersedia. Penggunaan biochar dari sekam padi menunjukkan peningkatan pH air yang lebih baik dibandingkan dengan tongkol jagung. Bahan baku biochar tongkol jagung lebih memenuhi standar baku SNI, namun penggunaan bahan baku biochar sekam padi memiliki potensi lebih tinggi untuk dikembangkan karena kelimpahannya.
English Abstract
Accumulation of toxic elements from pyrite oxidation and poor drainage systems cause very high soil and water acidity levels in Type B tidal swampland. The application of biochar in drainage channels can be an alternative to reduce the level of water acidity in the land. The objectives of this study were to (1) Evaluate the characteristics of biochar types placed in drainage channels to improve water acidity in Type B tidal swampland; (2) Evaluate the effect of biochar placement in drainage channels on improving water acidity in Type B tidal swampland; and (3) Evaluate the effect of biochar types on improving water acidity in Type B tidal swampland. The research was conducted in Belandean Village, Barito Kuala from October 2023 to March 2024. Analysis of water samples was carried out at the Integrated Laboratory of BSIP Swamp Land. The study used a Randomized Group Design with 3 replications and the treatments consisted of rice husk biochar and corn cob biochar placed in drainage channels. Variables observed were characteristics of biochar raw materials, biochar cation exchange capacity, pH, available Al, available Fe, and available SO 2- in water. The collected data were then subjected to T test, correlation test, and regression test. The results showed that the drainage channel was able to increase the pH in the water, which was followed by a decrease in the levels of available Al, available Fe, available SO 2-. The use of biochar from rice husks showed a better increase in water pH compared to corn cobs. Corn cob biochar raw materials meet SNI standards, but the use of rice husk biochar raw materials has a higher potential to be developed due to its abundance.
