Metode pengendalian gulma yang tidak efektif akan menyebabkan dinamika gulma ke jenis yang lebih sulit dikendalikan dan tertundanya matang sadap 2-3 tahun. Penelitian ini untukÂ mengkaji pertumbuhan gulma dan tanaman karet akibat pengaruh berbagaiÂ interval pengendalian dan aplikasi herbisida pada kebun karet TBM. Penelitian dilaksanakan dari Januari 2013 sampai Juni 2014.Â Rancangan penelitian Split Plot,Â petak utamaÂ adalah perlakuan intervalÂ pengendalian gulma dan perlakuan herbisida sebagai anak petak dengan ulangan 3 kali. Hasil penelitian menunjukkan bahwa pertumbuhanÂ gulma daun lebarÂ lebih dominanÂ (SDR 52,76%) dari gulma sempit (SDR 47,24%) di awal penelitian (pra perlakuan). Bobot kering dan penutupan gulma lebih rendah, padaÂ interval pengendalian lebih singkat. Bobot kering gulma antar petak perlakuan berbeda nyataÂ pada Juni dan Desmber 2013.Â Bobot kering dan penutupan gulma terendahÂ pada perlakuanÂ glifosat + metil metsulfuronÂ yang tertinggi pada perlakuan ditebas dan kontrol. Bobot kering dan penutupan gulma selalu berbeda nyata antara perlakuan glifosat + metil metsulfuron dengan perlakuan ditebas dan kontrol. Perlakuan herbisida campuran parakuat + metil metsulfuron menghasilkan pertumbuhan lilit batang karet lebih baik (17,9 cm) dibandingÂ perlakuan glifosat + metil metsulfuron (16,9 cm). Pertumbuhan lilit batang tanaman karetÂ sangat dipengaruhiÂ bobot keringÂ gulma dengan nilai koefisien diterminasiÂ R2 Â = 0,82. Dapat disimpulkan bahwa perlakuan herbisidaÂ glifosat + metil metsulfuron lebih efektif menekan pertumbuhan gulma danÂ pertumbuhanÂ lilit batangÂ karet sangat dipengaruhi bobot keringÂ gulma yang membentuk pola hubungan pertumbuhan negatif.

An integrated farming system is one of the alternatives for climatic change mitigation. This paper reports the application of corn-cattle based integrated farming system in Agrotechno Park Center of Palembang, and discusses its impact on CO2 fixation and the reduction of methane emissions. The study was based on the data of the first 6 yr from 2003 until 2009. The CO2 fixed in the soil and plants was determined based on the content of organic C which was multiplied by the index of 3.67. The methane gas produced by Balinese cattle and its dung was observed and modified into feed rations. The results showed that soil organic C increased from 40.80 tons C/ha in the 1st yr to 66.40 tons C/ha in the 6th yr. In addition, there was organic C fixation equivalent to 93.95 tons of CO2e. Corn biomass increased from 6.67 tons/ha to 18.66 tons/ha, equivalent to an increase in the fixation of atmospheric CO2e as much as 19.80 tons CO2e/ha. The supplementation of 60%-80% grass fodder with concentrate lowered the concentration of methane gas in cattle breathing by 28.7%, from 617 ppm to 440 ppm, while the methane emissions from cattle manure decreased by 31%, from 1367 mL/head/d to 943 mL/head/d. Installing a bio digester that generates biogas served to accommodate methane gas emissions from cattle dung and used it for bioenergy. Composting reduced the formation of methane gas from cattle manure through a regular process of turning over that gives aeration and forms aerobic condition in the heap of cattle dung. Recycling produces a variety of organic products that store carbon for a longer period of time and slowed the conversion of organic C into CO2. This study showed that the diverse activities of an integrated crop-cattle farming could be an alternative solution to climatic change mitigation.Key words: integrated farming, mitigation, organic C, methane, recycling

Weed is one of limiting factors in the direct-seeded rice cultivation. Cost incurred by farmers to control weeds is still quite high. Various techniques of weed control need to be evaluated to obtain the most effective weed control in tidal land. The experiment was conducted in tidal land fields in the Telang Â Sari village Tanjung Lago Sub District Banyuasin District during November 2012âˆ’March 2013. The experiment was arranged in a split plot design with planting density (K) as main plot and weeding methods (P) as sub plot. Five levels of planting density at 20, 40, 60, 80 and 100 kg rice seed/ha and four levels of weeding methods (manual weeding, dimethyl amine herbicide, penoxulam, and no weeding) were used in the experiment. The treatment was repeated 3 times and applied in 4Ã—3m plot. Components of plant growth and yield of rice plants were measured and analyzed using Microsoft Excel and SPSS 17.0. The results showed that methods of weed control did not significantly affect plant height, plant biomass at 4 weeks after seeding and number of tillers, but significantly affect number of empty grain and filled grain per panicle. Both planting density and method of weed control significantly affect yield, but no significant interaction between treatments. Planting density did not significantly affect plant biomass from age 8 weeks after seeding. Yield of planting density at 80 kg seed/ha was not significantly different from the yield of 40âˆ’60 seed/ha. Method of weed control was significantly affecting the rice yield. Weed control can increase crop yields by 37.7%.

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).
