Abstract

ABSTRAK. Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian campuran abu terbang-kotoran ayam (ATB-KA) terhadap perubahan titik muatan nol (TMN) tanah dan dampaknya terhadap jerapan dan ketersediaan P pada Ultisol. Dua perlakuan yang diuji adalah ATB-KA (w/w 1:1) pada dosis 0, 15, 30, 45 dan 60 ton ha-1, dan pemupukan P pada dosis 0, 87, 174, 261 dan 348 kg P2O5 ha-1.  Perlakuan ini ditata dalam Rancangan Acak Lengkap yang diulang sebanyak tiga kali. Hasil penelitian menunjukkan bahwa aplikasi CATK untuk setiap dosis pemupukan P berkorelasi secara nyata dengan status tanah TMN, pH, muatan negatif, jerapan dan ketersediaan P. TMN berkorelasi positif dengan pH dan muatan negatif. Muatan negatif secara nyata berkorelasi negatif dengan jerapan P, dan berkorelasi positif dengan P tersedia. Modification of PZS of Soil With Variable Charge by Application of Coal Fly Ash-Chicken Manure MixtureABSTRACT. The objective of current research was to study the effect of coal fly ash-chicken manure mixture (FA-CM) on the changes on the soil PZC status and its impact on P sorption and availability in Ultisols. Two treatments - FA-CM mixture (w/w of 1:1) at the rate of 0, 15, 30, 45 and 60 ton ha-1, and P fertilization at the rate of 0, 87, 174, 261 and 348 kg P2O5 ha-1 were tested.  These treatments were arranged according to Factorial Completely Random Design with three replicates. The results showed that the application of FA-CM for each dosages of P fertilizer correlated significantly with the status of soils PZC, pH, negative charge, P sorption and P-available. PZC has possitive correlation with pH and negative charge. Negative charge has a significantly negative correlation with P sorption, and posssitively correlation with P-available.

Abstract

ABSTRACT Changes in Point of Zero Charge and Negative Charge of Coal Fly Ash due to Chicken Manures Addition Fly ash, coal combustion residue of thermal power plants, has been regarded as a problematic solid waste all over the world. Due to the environmental problems created by large-scale fly ash generation, efforts are being made to recycle these materials, such as to improve soil fertility as an ameliorant. In the present study, the possibility to improving the status of point of zero charge (PZC) and negative charge in fly ash (FA) and chicken manure (CM) mixtures was investigated. Fly ash was mixed with chicken manure composition of 0, 25, 75, and 100 % FA (w/w basis) and incubated for 15, 30, 45, and 60 days. Treatments arranged in factorial completely randomized design with 3 replicates. The results showed that the compositions of FA-CM and incubation period significantly affect the status of TMN, negative charge, P sorption and available-P. The mix of 50% FA with 45 days incubation tend to have a lower PZC and P sorption and higher negative charge and P-available. This composition could be use as an amelioran to improve the soils chemical properties in terms to decrease PZC and increase negatif charge, and it is necessary for further research.   Keywords: chicken manure, coal fly ash, point of zero charge, negative charge

Abstract

Sektor pertanian menawarkan potensi sebagai mitigator dampak perubahan iklim. Sistem pertanian terpadu biocyclofarming (BCF) merupakan sistem yang memadukan tanaman-ternak diatur bersinergi sehingga terjadi siklus biologis. Karakteristik sistem BCF terkait dengan mitigasi dampak perubahan iklim adalah: adanya pengembalian limbah organik ke lahan, daur ulang yang memanfaatkan limbah, sistem pertanian tanpa limbah dengan menginstalasi bio-digester yang menghasilkan biogas. Makalah ini membahas sistem pertanian BCF berbasis tanaman jagungternak, dan mengevaluasi dampak aplikasinya terhadap penambatan C dalam tanah dan tanaman serta terhadap penurunan emisi gas CH4. Hasil kajian menunjukkan pengembalian bahan organik ke lahan meningkatkan penambatan CO2 dalam tanah dalam bentuk bahan organic tanah. Peningkatan C organik tanah berdampak positif terhadap kesuburan tanah, produksi biji dan biomas tanaman. Kandungan carbon tanah meningkat dari 2,04% atau setara dengan CO2 tertambat 40,80 ton/ha, menjadi 3,32% atau setara dengan 66,40 ton/ha pada tahun ke-6 aplikasi BCF, terjadi peningkatan carbon dalam tanah sebesar 3,65 ton/ha/th atau setara dengan penambatan 12,28 ton/ha/th gas CO2. Produksi biji jagung meningkat dari 2,1 t/ha menjadi 5,9 t/ha pada tahun ke 5 aplikasi BCF. Total biomasa tanaman meningkat dari 6 t/ha menjadi 16,8 (ton/ha). Sistem daur ulang teknologi BCF yang memanfaatkan limbah dari system usahatani yang satu menjadi input produksi usahatani menghasilkan produk yang menyimpan carbon merupakan teknologi mitigasi penambatan carbon dengan memperlambat konversi carbon menjadi gas CO2 atmosfer. Instalasi biodigester dalam teknologi BCF yang memanfaatkan limbah kotoran ternak guna menghasilkan biogas serta modifikasi ransum pakan pada ternak sapi merupakan teknologi mitigasi yang mampu menurunkan emisi gas CH4 dari kegiatan budidaya ternak sapi

Abstract

The influence of global climate to the Indonesian climate condition has been in serious condition which was already in high intensity. Flood becomes the fenomena in almost all area in Indonesia. In a swamp area, it can obstruct rice plant cultivation. The submerged rice plant create the obstruction of the rice plant photosynthesis and stress after being submerged. So that  an effort is needed to increase  its tolerance and recovery in order the reduction of the unhulled crop can be reduced.   This study was aimed to obtain a method to increase rice stage is vegetative  tolerance and recovery to submergence stress through the arrangement of nitrogen fertilizer aplication and rice variety.  The experimental design used was factorial completely randomized design with six replications. The factor consists of rice varieties (Inpara 3, Inpara 5, IR 64) and  treatment (P): P1: no submergence, all N dosage prior planting; P2: submerged (7-14 DAP), all N dosage prior planting; P3: submerged (7-14 DAP), all N dosage prior planting + (Si+Zn); P4: submerged (7-14 DAP), ½ N dosage prior planting + ½ N dosage 42 DAP + (Si+Zn); P5: submerged (7-14 DAP and 28-35 DAP), all N dosage prior planting; P6: submerged (7-14 DAP and 28-35 DAP), all N dosage prior planting + (Si+Zn); P7:  submerged (7-14 DAP and 28-35 DAP), ½ N dosage prior planting + ½ N dosage 42 DAP + (Si+Zn). The results showed that the arrangement of nitrogen fertilizer application before submerged to rice plant can increase the rice plant tolerance and recovery to the submerged stress.  The increasing of tolerance and recovery can be obtained at the rice variety given ½ N dosage prior planting + ½ N dosage 42 DAP + (Si+Zn).
