Based on an extensive literature review, bio-succinic acid (bio-SA) was produced via fermentation from oil palm fronds (OPF), which was then purified via vacuum filtration, evaporated, crystallised and dried to attain 99.27% purity. The purified bio-SA was then hydrogenated to produce 1,4-butanediol (BDO), prior to polymerisation with bio-SA to produce bio-PBS via esterification. The mass balance analysis performed with SuperPro Designer ® showed a negligible error. The proposed design gained profit in a short period of time based on 24.14% internal rate of return (IRR), 6.33 years dynamic payback period (DPP) and RM3366.31 million net present value (NPV). Direct comparison between simulation data and manual calculations showed <25.00% difference, which proved the dependability of the simulation results. Sensitivity analysis predicted that an increment in either bio-PBS’s production rate or bio-PBS and by-products pricing can increase the value of NPV and IRR. However, the increment in raw material price and fixed capital investment (C FCI ) can lower their values. Collectively, the results highlighted the feasibility of this process on a large scale as it has the potential to generate revenues, ultimately resulting in a sustainable bioplastic industry for packaging applications.","PeriodicalId":16613,"journal":{"name":"Journal of Oil Palm Research","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47816418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Quality oil palm seedlings with superior characteristics can be produced clonally using tissue culture techniques. The selection of explant sources is very important, and one of the explant sources that can be used is the young oil palm leaves. The ability of callogenesis and embryogenesis remains low, and this is thought to be related to endogenous hormones. This study is aimed to identify the types of endogenous hormones in explants of young clonal oil palm leaves and their relationship to callus and embryoid induction. The leaf midribs of six young oil palms were selected as explant sources. Explants were extracted and analysed for endogenous hormone content using high-performance liquid chromatography. The results of the analysis obtained various types of endogenous hormones in four oil palm clones. Zeatin hormones, ABA and IBA were found in two clones. Nine hormones were found in the other two clones, namely zeatin, kinetin, gibberellic acid, IAA, BAP, ABA, IBA, 2,4-dichlorophenoxyacetic acid, and naphthalene acetic acid with various concentrations. Young oil palm leaves with a more complete content of endogenous hormones have the potential to produce embryogenic callus in greater numbers and can produce embryoids to ensure that they can support the production of plantlets using tissue culture technology.","PeriodicalId":16613,"journal":{"name":"Journal of Oil Palm Research","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42858698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study assessed and estimated fish species richness and fish diversity in the tropical oil palm plantation in Terengganu, Peninsular Malaysia, along with their importance, and conservation status. From 57 fish species recorded, 28 species were suitable as ornamentals, 21 species for both food and ornamentals, and four species were considered suitable as ornamentals, food, and sport fishing. About 54 fish species were classified in the Least Concern (LC) category while one species each was classified in the Data Deficient (DD) and Not Evaluated (NE) categories. More species can be recorded by increasing the sampling efforts as suggested by Chao 1 species richness estimator. Tributary Sungai Nerus has the highest fish species diversity and species richness, while Sungai Jeneris has the lowest fish species diversity, species richness, and species evenness. Continuous data collection can determine the true fish species richness and fish diversity in the oil palm plantation, which can help to suggest good management schemes to conserve fish fauna in this agroecosystem.","PeriodicalId":16613,"journal":{"name":"Journal of Oil Palm Research","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2022-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47311732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Exoskeleton technologies are increasingly being explored for performance augmentation and ergonomics intervention in industrial settings. For challenging environments, like the oil palm plantation, the dynamic interactions between user, task and environment is non-trivial. Importantly, an exoskeleton should not impede a worker’s movement and task performance throughout the period of wear. Intrinsically, designing an exoskeleton for oil palm harvesting entails that the dynamic interactions between the harvester, the pole, and surrounding objects is considered early in the design process. We adopted the systems approach to designing an upper limb exoskeleton to assist oil palm harvesters. The proposed design is a slimline passive exoskeleton that provides an assistive force through compression springs in the upper arm region. Structural analysis and a preliminary prototype evaluation were performed for design verification. The weakest component was the back plate. Nevertheless, permanent deformation would only occur when an equivalent of 26 kg load is applied to the exoskeleton arm. Future work includes optimising the design and elucidating its long-term effects on the harvester’s efficiency and field productivity through biomechanical analysis and field tests.","PeriodicalId":16613,"journal":{"name":"Journal of Oil Palm Research","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42671644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considerable conidia production of CPMa1502 on MAYP (Maltose Agar Yeast with Potato Extract) and SMAYR (Sabouraud Maltose Agar with yeast extract and rice extract) agar was observed (1x10 9 conidia cm –2 at 14 days). The isolate was highly tolerant to a wide range of pH (5-9; germination >90%; radial growth rate: 0.95-1.02 mm day –1 ) but moderately tolerant to high temperatures (>35°C). Additionally, the adhesion capacity to D. neivai cuticle and conidial hydrophobicity was strong (114 conidia mm –2 : 72%). Finally, the insecticidal activity of CPMa1502 was greater on larvae than on adults, with a mean lethal concentration (LC 50 ) of 1.8x10 4 conidia mL –1 and a mean lethal time (LT 50 ) of 4.3 days, than on adults.

Thus, the objective of the current study is to evaluate the genetic variability of oil palm breeding populations using AFLP markers. The eight AFLP primer pairs utilised in this study generated 228 bands across 67 populations. As expected, populations created from intercrossing revealed relatively higher levels of genetic diversity compared with those derived from selfings. The dendrogram and Principal Component Analysis (PCA) of the DxD palms indicated a high genetic similarity. Among palms from the TxT/P crosses, the groupings were aligned according to the agency, signifying the accumulation of distinctive sets of alleles, likely due to the different selection pressure imposed by the respective agency. In PCA, the TxT palms, however, revealed a close genetic relationship indicating the need for incorporating new genetic resources to widen the genetic base. Based on the results, it is recommended the introduction of new genetic resources into the dura and tenera / pisifera populations. Additionally, crossing palms from populations of high genetic distances and adopting intercrossing scheme should result in off-springs with considerable diversity for selection gain in future breeding programmes.","PeriodicalId":16613,"journal":{"name":"Journal of Oil Palm Research","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2022-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46381996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As demand for palm oil grows in the international market, the industry has been experiencing mounting pressure to ensure sustainable development. The necessity for sustainable palm oil is amplified with European Union’s requirement for certified and sustainably produced palm oil to enter its market. The commodity is also inundated with anti-palm oil campaigns, which emphasise allegations of unsustainable practices. Collectively, these challenges pose a formidable impact on the palm oil trade. However, there are insufficient studies that review the existing literature on the challenges related to palm oil sustainability. Hence, this article presents a review on the environmental and health sustainability concerns the Malaysian palm oil sector faces when trading in the European market. The findings of the article suggest the development of strategies by multi-stakeholders to improve commodity competitiveness in the international market. One strategy proposed in this article is to engage the media and Non-Governmental Organisations in developing effective communication mechanisms to disseminate a more balanced perspective of the commodity. A positive voice on the existing sustainability measures could help shape an unbiased public opinion on palm oil production, trade, and consumption.","PeriodicalId":16613,"journal":{"name":"Journal of Oil Palm Research","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2022-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45035477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
