Plants get stressed shortly after submerged, to improve the recovery and subsequent metabolic processes as well as internal repairs required plant availability of adequate carbohydrate reserves after submerged. Giving fertilization treatment after being submerged is an effort to improve plant recovery after being submerged. This study was aimed to obtain the best fertilization to increase rice recovery to submergence stress through the fertilization after being submerged. The experimental design used was factorial completely randomized design with three replications. The factor consists of rice varieties (Inpara 3 dan IR 64) and treatment (N): Without soaking, basic fertilization (N1), submerged 7-14 DAP (fertilization of N, P2O5, K2O (N2), and fertilization of N, P2O5, K2O + (Si + Zn) (N3), as well as fertilization of N, P2O5, K2O + PPC micro (N4)) given 7 days after submerged, the submerged 7-14 and 28-35 DAP (N, P2O5, K2O (N5), and fertilization of N, P2O5, K2O + (Si + Zn) (N6) and fertilization of N, P2O5, K2O + PPC micro (N7)) given 7 days after the first submerged. The results showed that the growth and grain yield decreased with more frequent of rice plants in stress submerged condition. Fertilization can improve recovery after being submerged rice plants, where the best recovery obtained on varieties of rice plants treated with fertilization of N, P2O5 and K2O + PPC micro 7 days after being submerged.

The objective of this research was to study the effect of nutrient fertilization on the growth and development of nepenthes (Nepenthes mirabilis). The research was conducted from October 2011 until March 2012 at Sukarami village, Palembang, Indonesia. Factorial randomized block design with two treatment factors was applied. The first factor was NPK fertilizer dosage which consisted of three levels: Po = no fertilizer, P1 = 5 g, P2 = 10 g. The second factor was number of ants: S0 = none, S1 = 20, S2 = 40, S3 = 60. The results indicated that NPK fertilizer application of 5-10 g to the planting media could increase plant growth and development, particularly in plant height, stem girth, and leaf number of N. mirabilis. Giving 60 ants per plants into nepenthes pitcher could yield the largest pitcher number, 3-4 pitcher per plant. Combination of 5 g NPK and 20 ants, similarly, combination of 10 g NPK and 0 ants resulted in the largest leaf increment (10-11 leaves). Combination of 0 NPK and 60 ants resulted in the largest pitcher number (3-4 pitcher per plant).

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

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
