Effects of Organic Materials and Rainfall Intensity on the Productivity of Oil Palm Grown under Sandy Soil Condition

Oil palm plantations in Indonesia are cultivated on various types of land, ranging from very suitable  to unsuitable  types. This cultivation method is increasingly vulnerable to drought caused by climate change. Climate change due to global warming negatively affects the management of oil palm plantations in the long term.  The upper-temperature limit for efficient photosynthesis in oil palm leaves is >38 °C. The increase in temperature (2°C above the optimum) and rainfall by 10% is projected to cause a yield decline of up to 30%.  The water shortage is also a major limiting factor for palm oil production. Such vulnerability is predicted to worsen, and thus its negative effects should be explored. The purpose of this study is to reveal the role of organic matter applied as empty bunches (EFB) and the management of Nephrolepis bisserata vegetation in reducing the adverse effects of rainfall on palm oil production on sandy soils. The survey method and observations were carried out for over 3 years on plants aged 14–16 years on blocks. Empty fruit bunches (EFB) of 40 tons/ha/year was applied to each block, and Nephrolepis biserrata  was used as ground cover which planted in path. The parameters observed included the number and average weight of fresh fruit bunches (FFB). The relationship between fluctuations in the conditions of monthly rainfall intensity on oil palm production was determined through regression analysis.  Rainfall strongly influenced the number of FFB, whereas the average weight of FFB remained relatively constant. The application of EFB and management of Nephrolepis biserrata   vegetation facilitates the reduction of drought impacts and increase in oil palm production (15%) as shown in bunch weight and bunch number.  EFB and Nephrolepis biserrata  vegetation can increase soil organic matter content and improve soil water holding capacity

Collection and evaluation of wild and farmed stocks of giant freshwater prawn in Indonesia

Giant freshwater prawn is an important commodity that has been cultured successfully in Indonesia. Freshwater prawn farming has been adopted in several areas of West Java, i.e. Ciamis (Tambaksari, Parigi, Rancah and Pasir Nagara) and Tasikmalaya. Some commercial hatcheries are found in Jogjakarta, a local government hatchery, and seven private hatcheries. In East Java, freshwater prawns are farmed in brackishwater ponds. Freshwater prawn culture has also spread to some areas in Bali, e.g. Gianyar, Klungkung, Buleleng and Tabanan, as well as in Riau, South Sulawesi and South Sumatera. Inspite the development of freshwater prawn culture in Indonesia, some problems like slow growth rate, diseases and low carcass yield (small edible portion) remain unsolved. To address these problems, the Research Institute for Freshwater Aquaculture (formerly RIFF) started numerous genetic improvement programs since 1996 to improve growth rate and increase the animal’s edible portion. The genetically improved giant freshwater prawn stock named GI Macro (or Genetically Improved Macrobrachium), has been distributed to farmers particularly in Java. As reported in Nugroho and Emmawati (2004) and Nugroho et al. (2005), the performance of this stock in the different culture sites varied hence the development of a more suitable genetic base population with the use of other wild-sourced stocks in the continuous selection program was deemed necessary. An assessment of the genetic background of the wild stocks showed genetic divergence between giant freshwater prawns from western and eastern part of Indonesia (Nugroho et al., 2007). A performance evaluation of giant fresh water prawn stocks will be conducted to complement the above results in order to produce high quality giant freshwater prawn seedstock

Modified failure mode and effect analysis (FMEA) model for accessing the risk of maintenance waste

The existence of methodology for ranking and mitigating the risk of non-value added activities in manufacturing strongly support the realization of sustainable manufacturing practice. However, endeavours to create tools and methodology to rank the risk of non-value added activities are mostly devoted on product design and manufacturing and very rarely in maintenance engineering discipline. Motivated by such scarcity, the goal of this study is attempted to develop a modified FMEA (Failure Mode and Effect Analysis) as means to access the criticality of waste in maintenance operations. In an attempt to facilitate decision makers in appraising the criticality of maintenance waste occurrence, an improved model for ranking the risk of maintenance waste mode by using Waste Priority Number (WPN) is proposedAgung Sutrisno, Indra Gunawan, Stenly Tangkuma

Integrating SWOT analysis into the FMEA methodology to improve corrective action decision making

Improving the method for selecting risk-based competing improvement strategies has equal importance with failure risk quantification in the FMEA methodology. Nevertheless, there are few studies which focus on this issue. Furthermore, the influence of factors relating to the business environment which may support or derail improvement efforts is not considered in previous studies. In order to address these limitations, a model is proposed in which the impact of environmental factors is considered by integrating SWOT analysis into the FMEA method in order to support the appraisal of competing risk-based improvement efforts. The impact of SWOT variables is deployed using a decision support model based upon the benefit, cost, opportunity, risk and organisational readiness index (BCOR2) approach in order for the FMEA team to select from competing corrective actions. A case example from industry is provided in which the proposed model is applied. This example illustrates that this new model contributes successfully to good practice by identifying the most appropriate corrective action option to take and improves upon the decisions provided by existing developments of the FMEA methodolog
