PEMBERIAN KOMPOS TKKS DAN COCOPEAT PADA TANAH SUBSOIL ULTISOL TERHADAP PERTUMBUHAN BIBIT KELAPA SAWIT (Elaeis guineensis Jacq.)  DI PRE NURSERY

Palm oil (Elaeis guineensis Jacq.) is a plantation crop which is quite important in Indonesia because it accounts for foreign exchange and create employment that is high enough. Palm oil empty fruit bunches (EFB) is estimated at 20% of fresh fruit bunches ( FFB ) and coco in (cocopeat) are very much in Riau as raw material for fertilizer / compost. Subsoil ultisol a bottom layer of soil with sufficient depth within therefore very potential as a medium of palm oil nursery but has a low fertility signified by the nature of physics, chemistry and biology poor. Organic matter such as EFB compost and cocopeat can improve physical, chemical and biological subsoil ultisol. The research aimed to study the effect of EFB compost , cocopeat and a mixture of both the subsoil ultisol medium on the growth of palm oil seedlings in pre nursery. The study was conducted at the experimental station of Agriculture Faculty of the University of Riau from June to August , 2015. Research conducted an experiment using a completely randomized design (CRD) consisting of 6 treatments (K0 : without treatment , K1 : 100 g cocopeat , K2 : 100 g compost EFB , K3 : 50 g compost EFB + 50 g cocopeat , K4 : 75 g of compost EFB + 25 g cocopeat and K5 : 25 g compost cocopeat EFB + 75 g per plant) each repeated 4 times. The results showed treament EFB compost 50 g and cocopeat 50 g produce in the growth palm oil seedlings better than the other treatments on medium subsoil ultisol in pre nursery.

The increase of palm oil production produced waste, which has an impact on the environmental burden. Therefore, the purpose of this article is to predict the amount of palm oil empty fruit bunches produced per month in Indonesia to determine the potential of empty fruit bunches management. The predicted amount of the waste is based on crude palm oil (CPO) forecasts analysis that is processed using exponential triple smoothing. Based on the analysis, it was obtained that the amount of waste of empty fruit bunches proved to be directly proportional to the crude palm oil production. The efficiency of mill operation plays an essential role in CPO production and waste generation. However, this study has less variance on empty fruit bunches production since that quantity derived directly from CPO forecasting results based on fresh fruit bunches processed in the mills. Based on the estimation quantity, the management of palm oil empty fruit bunch as a raw material of fertilizer is sufficient to manage the produced empty fruit bunch. The data can be used to consider the waste palm’s potential management in palm oil mills and national scope.

ABSTRAK Kelapa sawit merupakan tanaman perkebunan yang memegang peranan penting dalam industri pangan. Luas perkebunan kelapa sawit di Indonesia pada tahun 2014 mencapai 10 juta Ha. Pertumbuhan yang pesat diikuti dengan produksi crude palm oil (CPO) dan palm karnel oil (PKO) yang juga meningkat, sekaligus produk sampingan berupa limbah. Salah satu limbah pabrik kelapa sawit yang jumlahnya besar adalah tandan kosong kelapa sawit (TKKS). Tandan kosong kelapa sawit merupakan limbah organik yang berpotensi dimanfaatkan dibidang pertanian. Akan tetapi, TKKS memiliki nilai C/N yang cukup tinggi, akibatnya sukar dan lama untuk terdekomposisi. Salah satu cara pemanfaatan TKKS adalah dengan dilakukan pengomposan dengan pengkayaan urea. Diharapkan dengan perlakuan tersebut TKKS akan cepat terdekomposisi dan dapat segera dimanfaatkan oleh tanaman. Penelitian ini bertujuan untuk (1) mengetahui pengaruh pemberian urea terhadap pengomposan TKKS dan (2) mengetahui pengaruh peningkatan dosis urea terhadap kualitas kompos TKKS. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) faktor tunggal dengan 5 perlakuan, yaitu U1 (urea 0 g setara dengan nilai C/N=), U2 (urea 30,9 g setara dengan nilai C/N=), U3 (urea 79,3 g setara dengan nilai C/N=), U4 (urea 176,1 g setara dengan nilai C/N=) dan U5 (urea 466,3 g setara dengan C/N = ) dan 9 ulangan, sehingga diperoleh 45 satuan percobaan. Hasil penelitian menunjukan bahwa pemberian urea berpengaruh sangat nyata terhadap susut bobot, kadar air, nilai pH kompos, C-organik, N-total, P-tersedia, dan nilai C/N, selain itu pemberian urea mengakibatkan terjadi perubahan tekstur dan warna pada kompos TKKS. Pemberian dosis urea 466,3 g mampu meningkatkan kandungan N-total, serta menurunkan nilai C/N dan nilai pH kompos. Pemberian dosis urea 79,3 g atau setara dengan C/N = mampu meningkatkan kandungan P-tersedia dan kadar air, menurunkan susut bobot dan kandungan C-organik, serta menunjukan perubahan tekstur dan warna yang lebih baik. Kata kunci: tanda kosongkelapa sawit (TKSS), kompos, urea ABSTRACT Empty fruit bunches (EFB) is a solid wastes produced in large quantity from palm oil industry. Empty fruit bunches can be used as compost material, additionally difficult to decompose because it contain cellulose, hemicellulose, and lignin, as well as value of ratio C/N is high. Use EFB as compost material through the provision of urea has been done in this research. Urea are expected to reduce the value of ratio C/N and became a starter for microbial decomposers. The purpose of this research were (1) to determine the effect of urea on composting of EFB and (2) to determine the effect of increasing doses of urea to the quality of compost of EFB. This research was used a single factor of Completely Randomized Design (CRD) with 5 treatments, namely U1 (urea 0 g), U2 (urea 30,9 g), U3 (urea 79,3 g), U4 (urea 176,1 g), and U5 (urea 466,3 g), and 9 replications, until result 45 experimental units.

AbstractThis research aims to know the physical characteristics and the palm oil production on a variety of land suitability. Randomized block design by survey method was used in this research that had been carried out in society’s enterprise. The research object was the palm oil crop cultivated in the lowlands (0-100 m above sea level), moderate land (100-500 m above sea level), and the highland (>500 m above sea level). The plant wich is taken as a sample is a plant which was 10 years old (already production). The villages in the survey, set in accordance with the height. The observed variables in this study i.e.; the circumference of the trunk, tall trunk, leaf stem length, color and thickness of the leaf, heavy of fresh fruit bunches, the age of starting production, production and productivity. Other observed data is temperature and soil acidity. To see the difference between production and productivity of palm oil on three ecology types of land, observed data were analyzed using analisys of varians that followed by Duncan test (α = 5%). The land suitability has significant on physical characteristics and palm oil production. Palm oil production in moderate land was significantly higher than those in both the high and lowland. Keywords; crop production, physical characteristics, land suitability, palm oil.

It is necessary to know the effect of excessive salinity in the soil on the growth of the African palm crop. The objective of the work was to evaluate the effect of salinity caused by NaCl on the growth and absorption of nutrients in the oil palm crop in early growth stage. The research was carried out in the laboratories of the University of Cordoba, where the 16 kg experimental units were made up of a mixture of alluvium and rice husk in a ratio of 4: 1. A complete randomized design was used with six treatments and a control (0.0, 0.5, 1.0, 1.5, 2.5, 3.6, and 6.1 cmolc kg-1 Na) and four repetitions. The data were statistically analyzed by analysis of variance and regression. The results report that the salinity in the soil that originates with the application of 2.5 cmolc kg-1 of Na produces in the soil an electrical conductivity (EC) of 1.96 dS m-1. Consequently, a drastic reduction in the quantified biomass of dry mass of stem, leaf, roots, rachis and leaf area originates, and the models that express this trend were adjusted to decreasing linear regressions with their highly significant parameters. Salinity interferes with the absorption of nutritional elements, such as N, K+ and Mg2+, and foliar nitrogen is the nutrient with the highest sensitivity to variations in EC in the soil. Foliar phosphorus (P) and calcium (Ca) concentrations were not affected by salinity levels.
