Abstract

Pemanfaatan beberapa jenis urin ternak sebagai pupuk organik cair dengan konsentrasi yang berbeda pada tanaman kelapa sawit (Elaeis guineensis Jacq.) di pembibitan utama Utilization of livestocks urine as a liquid organic fertilizer with different concentrations on oil palm (Elaeis guineensis Jacq.) in main nursery Abstract. Seedling is an initial stage in the cultivation of oil palm, seed quality will affect the results that will be obtained later. Factor affecting the growth of seedlings of which the availability of nutrients which can be obtained from inorganic and organic fertilizer. Application of inorganic fertilizer without an organic fertilizer balanced can be damage the nature of the soil, necessitating organic fertilizer the urine of livestocks as organic liquid, adding organic liquid fertilizer to the soil, can help the plants to growth because organic liquid fertilizer of livestocks urine contain growth hormone for plants and easily absorbed to the plants. The research was conducted in Experimental Station of Ciparanje, Faculty of Agriculture, Padjadjaran University, Sumedang, from September 2017 to February 2018. Ordo of the soil used is Inceptisol. Precipitation type according to Schmidt and Ferguson's classification of type C with ± 780 meters above sea level altitude. Experiment was using a randomized block design (RBD) with 11 treatments with 3 replications and the number of plants in each plot of 2 plants. The treatment consists the urine of cows, goats and rabbits with some concentration of 40 mL/L of water, 120 mL/L of water and 200 mL/L of water as well as a comparison treatment, control (untreated) and the provision of urea fertilizer 3,3 g/plant. The results showed that the utilization some kinds of cattle urine provides a good effect on plant growth, which is reflected from the dry weight of the plant. Treatment goat's urine concentration 40 mL/L of water and 120 mL/L of water tends to affect on the dry weight shoot, dry weight root, and shoot root ratio on seedling oil palm.

Integrated livestock and oil palm plantation as sustainable agricultural bioindustry in Bangka Island, Indonesia

“…This was due to the farmer used organic fertilizer from livestock (manure and urine) that lead to the increase of productivity (Table 1). Urine from livestock has been reported can give positive effect to the growth of oil palm [16]. Another group of researcher also reported that livestock give several benefit to the palm oil plantation in integration system that lead to the improvement of farmers income in Malaysia.…”

Potential of goat manure as organic fertilizer in North Sumatera

“…The potential of liquid organic fertilizer production from goats in North Sumatera was 502,724,000 L/year (Table 1). Meanwhile, goat urine contains macronutrients of 1.13% N, 0.05% P2O5, 7.9% K2O [3] and other micronutrients. To obtain a better quality of liquid organic fertilizer, goat urine is usually first fermented with microorganisms.…”

“…After 30 days of composting, the nutrient content reached 2.23% N, 1.24% P2O5, and 3.69% K2O [2]. Besides, goats also produce urine which contains nutrients such as 1.13% N, 0.05% P2O5, and 7.9% K2O [3].…”

Respon Pemberian Pupuk Urea dan Urine Sapi terhadap Pertumbuhan Bibit Kelapa Sawit (Elaeis guineensis Jacq.) di Pembibitan Awal

“…Penelitian Alvi et al, (2018) melaporkan kandungan urin sapi memiliki pH 8,25; N-total 0,23%; P2O5 0,07%; dan K2O 1,70% serta pemanfaatan urin ternak sebagai pupuk organik cair pada tanaman kelapa sawit dipembibitan utama tidak memberikan pengaruh terhadap pertumbuhan bibit kelapa sawit. Lubis & Sjofjan, (2016) menyatakan bahwa pemberian urine sapi berpengaruh tidak nyata terhadap tinggi bibit, jumlah daun, diameter bonggol, volume akar, rasio tajuk akar, tetap berpengaruh nyata terhadap bobot kering bibit kelapa sawit dengan konsentrasi urin sapi 60% menunjukkan bobot kering tertinggi.…”
