“…The experimental design was completely randomized with three replications for each treatment. The experimental tests were performed under variable load conditions (0, 20, 40, 60, 80 and 100%) according to Indian Standard (IS: 10,000, Part VIII), and fuel consumption was measured following Indian Standard (IS: 10,000, Part IV) for each test fuel (Gangwar and Agarwal 2008;Sidibe et al 2020). These tests were conducted in governorcontrolled range.…”

The aim of this study was to find out the thermal and environmental performance of a four-stroke, single-cylinder, direct injection 10-kW CI engine at varying engine load conditions using different test fuels. The formulated fuels, viz. CeO 2 nanoparticles-dispersed water-diesel-biodiesel fuel blend (CNWEDB) and water-diesel-biodiesel fuel blend (WEDB), were prepared using emulsification technique using CeO 2 nanoparticles and water as additives in diesel-biodiesel blend (B20). The measured fuel properties of CNWEDB and WEDB satisfied the criteria of Indian Standard for biodiesel indicating their suitability for use in CI engine. The engine was run at various loads (0, 20, 40, 60, 80 and 100%) randomly to assess its thermal and environmental performance with all test fuels. Thermal performance of CI engine was evaluated by measuring the parameters such as brake thermal efficiency (BTE), brake-specific fuel consumption (bsfc), exhaust gas temperature (EGT) and heat balance for all test fuels. The environmental performance of engine was assessed by measuring CO, HC and NO x emissions for all test fuels. Adding water and CeO 2 nanoparticles into B20 improved BTE of engine by 7.65% over diesel. Also, the minimum heat losses were observed at 80% engine load for CNWEDB indicating a better conversion of fuel energy to useful work. EGT and bsfc of engine reduced with CNWEDB over WEDB and B20 fuels. Engine fueling with CNWEDB emitted 12.82%, 14.46% and 14.20%; and 30.77%, 43.67% and 26.80% lesser concentration of CO, HC and NO x emissions over WEDB and diesel, respectively.Editorial responsibiility: Q.

“…A blend of 80% fossil diesel and 20% Jatropha oil (which is described as a J20 grade) was found to give similar combustion performance and emissions to those corresponding to using pure fossil diesel. In addition, it was found that that the high viscosity of vegetable oils is not essentially responsible cause of degraded combustion performance in a diesel engine, which leads to carbon deposits (unburned matter due to incomplete combustion) in the combustion chamber (Sidibé et al, 2020).…”

<i>Jatropha Curcas</i> as Marginal Land Development Crop in the Sultanate of Oman for Producing Biodiesel, Biogas, Biobriquettes, Animal Feed, and Organic Fertilizer

The present article can be regarded as a compilation of various aspects related to the cultivation and utilization of Jatropha curcas in degraded lands, which may not be very suitable for other crops. The benefits of this plant are not limited to producing biodiesel, but expand to biogas and biobriquettes. So, all three phases of fuel (liquid, gas, solid) are possible outcomes from it. Aside from fuels, the byproduct seedcake resulting from pressing the seeds can be used as a good organic fertilizer that is comparable or even better than chicken manure. After detoxification, this seedcake can be valuable feed for livestock. Along with the positive expectations, the study is balanced by also addressing negative expectations when planting Jatropha curcas for commercial applications. A seeds sample of this plant was successfully germinated in indoor condition, after applying the shell cracking pre-treatment. Special attention is paid to the Sultanate of Oman as a country whose geographic location and vast desert lands may encourage large-scale investment in Jatropha curcas for boosting and diversifying the economy.

“…Renewable biofuels derived from agricultural biomass are much needed as the global supply of fossil fuels is in crisis (Baral et al 2020). Among numerous biomass crops, Jatropha curcas (L.) represents a promising candidate, and therefore a lot of researches has been conducted to maximize its exploitation (Sidibe et al 2020). Due to its hardiness and adaptability to wide agroclimatic conditions, J. curcas is cultivated throughout the world (Ntaribi and Paul 2018).…”

Evaluation of indigenous fungal entomopathogens and aqueous leaf extract of Annona muricata against Polyphagotarsonemus latus infesting Jatropha curcas in Indonesia

Abstract. Puspitarini RD, Afandhi A, Fernando I. 2021. Evaluation of indigenous fungal entomopathogens and aqueous leaf extract of Annona muricata against Polyphagotarsonemus latus infesting Jatropha curcas in Indonesia. Biodiversitas 22: 2648-2655. The broad mite Polyphagotarsonemus latus (Banks) (Acari: Tarsonemidae) has been known to cause a great deal of injury on Jatropha curcas (L.) plantation in Indonesia. Isolation of indigenous fungal entomopathogens from rhizosphere soils, followed by pathogenicity assay was conducted to find an effective isolate for controlling P. latus. Additionally, the potential combination of the selected isolate and soursop (Annona muricata L.) aqueous leaf extract (SLE) was investigated. A total of 24 isolates were obtained by using the insect bait method. Four fungal isolates, namely Paecilomyces sp. 1., Lecanicillium sp., Beauveria sp., and Fusarium sp. 1, showed high conidial viability and were chosen as representatives to assess their pathogenicity against P. latus. Among the tested isolates, Beauveria sp. which had the highest conidial viability among the tested isolates, needed a shorter period to completely kill the tested mites. However, the compatibility test revealed the deleterious effect of SLE on Beauveria sp. SLE at all concentrations showed a very toxic effect on the fungus, therefore the two must be applied separately. Our results provide useful information on the effectiveness of indigenous entomopathogenic fungi Beauveria sp. and aqueous leaf extract of A. muricata as an alternative tool to control the broad mite P. latus on the J. curcas plantation.
