Hydrolysis of Empty Fruit Bunches of Palm Oil (Elaeis Guineensis Jacq.) by Chemical, Physical, and Enzymatic Methods for Bioethanol Production

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.

Elaeis Guineensis Jacq

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. AbstrakPenelitian ini bertujuan untuk mengetahui karakteristik fisik dan produksi kelapa sawit (Elaeis guineensis Jacq) pada berbagai agroekologi lahan. Percobaan dirancang menggunakan Rancangan Acak Kelompok (RAK), dilakukan di kebun rakyat dengan metode survey. Objek yang diteliti adalah tanaman kelapa Sawit yang dibudidayakan di dataran rendah (0-100 m dpl), dataran sedang (100-500 m dpl_, dan dataran tinggi (>500 m dpl). Tanaman yang diambil sebagai sampel adalah tanaman yang berumur 10 tahun (telah berproduksi). Desa-desa yang di survey, ditetapkan sesuai dengan ketinggian tempat. Peubah yang diamati dalam penelitian ini yaitu ; lingkar batang, tinggi batang, panjang pelepah, warna dan ketebalan daun, berat tandan buah segar, umur mulai berproduksi, produksi dan produktivitas, serta tindakan agronomi. Data lain yang diamati adalah suhu dan kemasaman tanah. Untuk melihat perbedaan produksi dan produktivitas kelapa sawit pada tiga jenis agroekologi lahan, data hasil pengamatan lapangan dianalisis menggunakan analisis ragam yang dilanjutkan dengan uji Duncan dengan α 5%. Agroekologi lahan berpengaruh nyata terhadap karakteristik fisik dan produksi kelapa sawit. Produksi tanaman kelapa sawit di daerah dataran sedang lebih tinggi dan berbeda nyata dengan produksi tanaman kelapa sawit daerah dataran tinggi dan daerah dataran rendah. Kata Kunci ; produksi tanaman, karakteristik fisik, kesesuaian lahan, kelapa sawit

Esta pesquisa teve como objetivo avaliar a ﬂutuação populacional de Rhynchophorus palmarum L. (Coleoptera: Curculionidae) em plantios de Elaeis guineensis Jacq, em ecossistemas de savana e floresta no estado de Roraima. A pesquisa foi desenvolvida durante o período de janeiro de 2011 a fevereiro de 2012 nos campos experimentais da Embrapa Roraima: Monte Cristo e Caroebe, numa área de 2 hectares com a cultura da Palma de Óleo, em cada campo. Foram distribuídas armadilhas iscadas com roletes de cana-de-açúcar e feromônio de agregação para captura dos insetos no entorno dos plantios. Ocorreu flutuação de R. palmarum com picos populacionais nos meses de julho e agosto no ecossistema de savana e de abril a setembro no ambiente de floresta. A população de R. palmarum foi menor em meses de baixa precipitação pluviométrica nos dois ambientes avaliados com a Palma de Óleo em RoraimaPopulation Fluctuation of Rhynchophorus palmarum L. (Coleoptera: Curculionidae) in Plantations of Oil Palm in RoraimaAbstract. This research aimed to evaluate the population fluctuation Rhynchophorus palmarum L. (Coleoptera: Curculionidae) in Elaeis guineensis Jacq plantations in forest and savanna ecosystems in the state of Roraima. The research was conducted during the period from January 2011 to February 2012 in the experimental field of Embrapa Roraima: Monte Cristo and Caroebe in an area of 2 hectares with culture Oil Palm in each field. Traps baited with rollers cane sugar and aggregation pheromone for capturing insects in the vicinity of the plantations were distributed. Fluctuation occurred R. palmarum with population peaks in the months of July and August in the savanna ecosystem and from April to September in the forest environment. The population of R. palmarum was lower in months of low rainfall in the two environments assessed with a palm-oil-in Roraima.
