Abstract

Oil palm is a very significant industrial plant in producing vegetable oils that require high levels of nutrients in its cultivation. Cultivation of oil palm yield can produce industrial waste, the oil palm empty trunks (TKKS) which have the potential to supply nutrients to oil palm land. The placement of empty trunks at various depths is expected can give effect to the population of Oryctes rhinoceros L pre-adult stage and chemical soil properties. This research was conducted on oil palm plantation in PT. Perkebunan Nusantara V Sei Galuh Tapung, Kampar, Riau from July to October 2017. The aim of this research is to examine the effect of empty trunks placement against the Oryctes rhinoceros L population development and chemical soil properties. This research was done using a randomized experiment design complete with the treatment of the depth empty trunks placement (placement of oil palm empty trunks on the ground at the depth of 10 cm, 20 cm, and 30 cm) which is repeated four times. The observed parameters include the population of infestation of Oryctes rhinoceros L (population of eggs, larvae and pupae) and soil chemical properties (soil pH, C-organic, N-total, P-total and K-total). The results showed that empty trunks placed below the surface at various depths affected the Oryctes rhinoceros L population. Placement of TKKS depth in the soil cannot be infested by Oryctes rhinoceros L. Placement of empty trunks at the depth of the soil tends to increase pH (from very acidic categories to acidic categories) and total K (from the low category to very high category), is not effected on C-organic and N-total and can reduce P-total (from the very high category to the high category) if compared to the placement of empty trunks on the ground.Key words : Chemical Soil properties, Oryctes rhinoceros L., Oil palm Empty trunks, Soil depth

Abstract

The wider the area of oil palm plantations in Indonesia, the more palm oil mills will process more oil palm fruit bunches and produce waste one of them is liquid waste. The amount of liquid waste that is more and more if not treated properly will cause environmental pollution. The research aim to study the effect of liquid waste of oil palm factory (LWOPF) with biopori method to the growth of immature oil palm plant. The experiment was conducted in oil palm plantation of Agricultural Faculty of Riau University from May to July 2017. The experiment was arrange drandomized complete design consisting of 13 treatments (without LWOPF; 5; 7.5 and 10 liters LWOPFeachapplied in 1, 2, 3 and 4 biopore/plants), each repeated three times.The parameters observed were plant height, number of midrib, length of midrib, number of leaves, width and length of leaves. The results showed that the application ofLWOPF dose 7.5 liters applied in 4 biopore holes / plants increased addition the number of midrib and the leaves, the width and length of the leaves compared to without LWOPF and the highest than another treatment, but the addition of plant high increased at doses 7.5 liters in 3 biopore/plant and highest than another treatment.Key words : Liquid Wastes of Oil Palm Factory, Biopore Holes, Oil Palm Plants

Abstract

Fertility of peat land is very poor and makes it not suitable for crop without any high input.  This condition was indicated by the very high soil acidity ( low pH), low availability of macro (N, K, Ca and P), and micro (Cu, Zn, Mn and Bo) nutriens and high cation exchange capacity (CEC) but low base saturation (BS), the presence of toxic organic acid. The main organic acids, as a result of lignin biodegradation and the sources of C-release, are of aromatic group consisting mainly of derivate phenolic acids. The peat soil material was taken at depths from 0 to 30 cm, with weathering rate saprik and dregs from Indah Kiat Pulp and Paper at Perawang, Riau. These experiments using split plot design, the main plot is the condition of the water (unsaturated and saturated) and the subplot is ameliorant dregs consisting of 4 levels (0, 10, 15 and 20 ton ha-1), each combination was repeated 4 times. The activities were focused on the interaction of water condition and ameliorant dregs, and its influences to growth and yield of rice, C-emission (CO2 and CH4). The results showed that the aplication of dregs improves plant growth and increase the yield of rice (weight of dry milled grain) compared without dreg both at unsaturated condition and saturated conditions. The Cabon-release in the forms of CO2 and CH4 fluxes in saturated conditions is smaller than unsaturated conditions. The application dreg 10 t ha-1 increase the number of productive tillers and the weight of milled rice about 35 and 75% compared without dreg on saturated condition, whereas the increase is greater unsaturated conditions about 63 and 80%. The application of dregs 10 t ha-1 in saturated condition can reduce CO2 and CH4 emissions about 18.19% and 93.71% compared without dreg, otherwise the application dreg 10-20 t ha-1 increase the production of CO2 and CH4 in unsaturated conditions.

Abstract

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.
