The magnetic adsorbents i.e. oil palm frond-magnetic particles (OPF-MP) and oil palm frond activated carbon-magnetic particles (OPFAC-MP) have been prepared by impregnation of iron oxide via co-precipitation method. The magnetic adsorbents and their parent materials were characterized using Fourier transform infrared (FTIR), thermogravimetric analysis (TGA), field emission scanning electron microscopy (FESEM), Brunauer Emmett Teller (BET), Barrett, Joyner & Halenda (BJH) and t-plot method, x-ray diffraction (XRD) and also using vibrating sample magnetometry (VSM) to study their properties and surface chemistry. The activated carbon magnetic adsorbent confers high surface area of 700 m2/g with amorphous structure and magnetic properties of 2.76 emu/g. The OPF-MP and OPFAC-MP were then applied in adsorption study for ions removal of Pb(II), Zn(II) and Cu(II). OPFAC-MP has shown high removal efficiency of 100 % with adsorption capacity up to 15 mg/g of Pb(II), Zn(II) and Cu(II) ions compared to OPF-MP. In addition, the magnetic adsorbents were also compared with their parent materials to observe the effect of magnetic particles. Accordingly, the impregnation of magnetic particles enhances the metal ions adsorption comparing to their parent materials.
Black spot disease is a significant worldwide disease on the rose plant. Due to this infection, the leaves become yellow and eventually fall off. The occurrence of this disease has become a major problem, especially in landscape purpose. Therefore, this research was conducted to isolate fungal species from black spot disease in rose and identify using morphological characteristics. Then, all the isolates were tested for pathogenicity to confirm Koch’s postulates. In this study, four fungal isolates have been successfully isolated from black spot disease in rose namely Rhizoctonia sp. (one isolate), Colletotrichum sp. (two isolates) and Penicillium sp. (one isolate). Based on pathogenicity test result using potato dextrose agar (PDA) plug technique, fungus UMTT27R (Penicillium sp.) showed highly pathogenic on rose’s leaves with disease severity (DS) = 88.89% followed by UMTT13R (Colletotrichum sp.) with DS=72.22%, UMTT21R (Colletotrichum sp.) with DS=66.67% and UMTT4R (Rhizoctonia sp.) with DS=61.11%. Correct identification of fungal pathogens is very important to strategize a proper method to control the black spot disease in rose cultivation.
Many chilli producers in Malaysia are facing a huge problem of anthracnose disease that infect the chilli fruits either at pre- or post-harvest stage. Due to this infection, the chilli fruits become rotten and could be colonized by grey conidial masses which is unfit for human consumption and cannot be sold. This study was aimed to isolate the fungal species associated with anthracnose symptoms collected from several mini-markets near Gong Badak, Terengganu. Pathogenicity test was conducted for all these isolates to evaluate their pathogenic level. Based on the results, five fungal isolates were successfully isolated and morphologically identified as Colletotrichum spp. All these isolates were labelled as UMTT46C, UMTT48C, UMTT50C, UMTT52C and UMTT54C. From these, fungal isolate (UMTT54C) showed the highest pathogenic level with disease severity (DS), 68.9%. Other Colletotrichum spp. recorded percentage of DS ranged from 53.3% to 60%. Identification of fungal isolates and their pathogenic level from the infected chilli is very important to assist in control strategy which can further provide a good protection measure for many chilli producers.
In Islamic transaction, the disputations between two or more parties could affect the roles and responsibilities. Furthermore, when the court received a case from disputed parties, there will be a perception among each of parties of win-lose situation, whereby one party embellished with satisfaction, while the other party will beat in suffering, so the impact is the relationship between two parties are become farther. Therefore, alternative dispute resolution (ADR) in Islamic Finance is suggested in by many Muslim economist and legal experts as a substitute to any further legal activities. This is because it will satisfy many of litigants and it provides a complementary substitute to litigation. The study about ADR in Islamic finance has been done by previous literature. By the way, the implementation of ADR in Islamic financial institutions still needs to be elaborated. Therefore, this paper aims to discuss about updated issues and challenges of implementations of ADR in Islamic finance. This paper found that the ADR in Islamic finance need a model to make the ADR more flexible and eligible with different kinds of conflicts.
