Abstract

The bamboo strips and oil palm trunk veneers were laid-up together alternately using phenol formaldehyde (PF) adhesive to form composite lumber with two different types of layer orientation. The composite lumber was hot pressed at two different pressing times. Physical properties test, such as cold water and hot water delamination, as well as mechanical properties test, such as flexural and compression were conducted according to a specific standard. Results showed that longer pressing time has increased all properties, except flexural and compression. Cross orientation has increased the bonding strength behaviour between bamboo strips and oil palm trunk veneers, thus influenced the low delamination percentage and good modulus of elasticity value. It is observed that the different failure behaviour was influenced by different types of layer orientation, especially in compression and physical properties. Different pressing times had not influenced any difference of failure modes.

Abstract

This paper discusses the results from the initiative that has been undertaken to utilize residues from oil palm re‐plantation, particularly the oil palm trunk (OPT) for the production of laminated veneer lumber (LVL). Efficient use of such residues is vital in order to minimize the environmental burdens associated with the disposal of the oil palm residues, thus ensuring the future growth of Malaysian palm oil industry. The bending and compression strength of the OPT LVL produced were accessed and compared with Malaysian oak (formerly known as rubberwood), timber species that is commonly used in the manufacture of furniture in Malaysia. Properties of OPT LVL were found almost comparable to solid Malaysian oak in terms of bending and compression strength. Combination of OPT veneers with several layers of Malaysian oak veneers during the process of LVL manufacturing has resulted in the improvement in bending and compression strength of the LVL as compared to those produced entirely from OPT. In addition, such practice also produced LVL board with far less variation in strength properties as compared to solid OPT properties. With further research and development embarked upon the gluability of the OPT materials, the overall performance of the OPT LVL could be improved for commercial utilization of OPT wastes in the near future. Development higher value‐added by‐products from oil palm industry residues, would benefit the industry through reduction of the overall environmental burden and would place it on a new environmentally sustainable platform.

Abstract

Purpose

The purpose of this paper is to develop strategies for potential environmental impacts as a result of institutional arrangement and development of oil palm downstream industry both regionally and nationally.

Design/methodology/approach

The research location is in the areas potential for oil palm plantation development, either by plasma through BUMN and BUMS or self-supporting by the society. The research location will be divided into two parts, namely, the land area and the coastal area. The Riau land areas are Regency of Kampar, Rokan Hulu, and Kuantan Singingi, while Riau coastal areas are Regency of Pelalawan, Siak, Bengkalis, Indragiri Hilir, Indragiri Hulu and Rokan Hilir. Both research areas have different productivity due to the different soil fertility levels. The sustainability level of oil palm plantation from the socio-economic and environmental aspects is analyzed using the multi-dimensional scaling approach modified into Rapid Appraisal-Index Sustainability of Palm Oil Management.

Findings

In Riau Province, the development of oil palm is quite rapid. This is reasonable for several reasons which include the following supporting factors: the geographical condition of the Riau region is very supportive; the high demand for palm oil derivative products; the existence of market guarantee for oil palm farmers; the higher income oil palm generates than other plantation crops; and the relatively flat area. Most of the problems faced by oil palm farmers are the use of less good seeds, the length of the fruit laying at the location of the plantation, the inadequate production road, the relatively far distance to palm oil mill (POM) (National Agency of Drug and Food Control), the tendency of determining the unilateral revenue of the POM, the collectively measurement of revenue and the general revenue information. The development of oil palm plantations has created an entrepreneurial capability for farmers who are able to capture business opportunities in the agricultural sector, especially the plantation sub-sector.

Originality/value

The originality of this paper shows the comprehensively control strategy, potential of environmental impact and palm oil plantation. The method used for data collection was rapid rural appraisal method because accurate information is needed in a limited time as it relates to decisions related to village development that must be taken immediately. The study area was conducted in Riau Province because Riau Province is one of the biggest palm oil producers in Indonesia. The study sites will be divided into two, namely, the land area and the coastal area.

Abstract

Purpose

This study aims to determine the optimum model of oil palm empty bunches (OPEB) management, to determine the optimal number of OPEB in waste management, which is then recommended to the company, and to know the achievement of various goals/targets with limited availability of resources.

Design/methodology/approach

This research uses quantitative and qualitative approaches. Quantitative approach is done by processing the data for financing and profit analysis in OPEB waste management which is then used for resource approach. A qualitative approach is undertaken for weighing purposes in the analytic hierarchical program (AHP) analysis. The research location was determined purposively in the crude palm oil mill of PT. Pundi Lahan Khatulistiwa in Ambawang, Kubu Raya Regency.

Findings

In order that the optimal settlement can achieve the goal/target of minimal environmental pollution, low cost and profit gain, the amount of OPEB that must be managed by the company is 311 tons prioritized for productive plants compost of 66.67 tons, organic fertilizer of 11 tons and mushroom growing media of 233.33 tons. Consequently, the company's cost of IDR 4.000.000.000 still spares IDR 2.004.694.000. The OPEB management as oyster mushroom promises a relatively high profit compared to other OPEB managements even though the cost is not the least.

Originality/value

This research is one of the few studies that examines the waste management model of palm oil empty bunches, mainly located in West Kalimantan, Indonesia. Originality is seen from the use of optimization analysis tools with integration of AHP with goal programming.

Abstract

IT is nearly three and a half centuries since John Donne, preaching in St. Paul's Cathedral, of which he had recently become Dean, said: ‘Some men, by the benefit of this light of Reason, have found out things profitable and use‐ful to the whole world; as in particular Printing, by which the learning of the whole world is communicable to one another, and our minds and inventions, our wits and compositions, may trade and have commerce together, and we may participate of one another's understandings, as well as of our Clothes, Wines, Oyles and other Merchandize.’

Abstract

Purpose

There is growing evidence of a knowledge gap in the association of maintenance with production activities in bottling plants. Indeed, insights into how to jointly optimise these activities are not clear. In this paper, two optimisation models, Taguchi schemes and response surface methodology are proposed.

Design/methodology/approach

Borrowing from the “hard” total quality management elements in optimisation and prioritisation literature, two new models were developed based on factor, level and orthogonal array selection, signal-to-noise ratio, analysis of variance and optimal parametric settings as Taguchi–ABC and Taguchi–Pareto. An additional model of response surface methodology was created with analysis on regression, main effects, residual plots and surface plots.

Findings

The Taguchi S/N ratio table ranked planned maintenance as the highest. The Taguchi–Pareto shows the optimal parametric setting as A4B4C1 (28 h of production, 30.56 shifts and 37 h of planned maintenance). Taguchi ABC reveals that the planned maintenance and number of shifts will influence the outcome of production greatly. The surface regression table reveals that the production hours worked decrease at a value of planned maintenance with a decrease in the number of shifts.

Originality/value

This is the first time that joint optimisation for bottling plant will be approached using Taguchi–ABC and Taguchi–Pareto. It is also the first time that response surface will be applied to optimise a unique platform of the bottling process plant.
