Resilience to Disturbance Despite Limited Dispersal and Self-Recruitment in Tropical Barrel Sponges: Implications for Conservation and Management
TL;DR: This study finds the highest abundance of both barrel sponge species (although they were generally smaller) at a site that has been severely impacted by humans over the last fifty years, suggesting that barrel sponges exhibit environmental adaptation to declining environmental quality and has important implications for the management and conservation of these important reef species.
Journal ArticleDOI
The Influence of Si:Al and Na:Al on the Physical and Microstructure Characters of Geopolymers Based on Metakaolin
TL;DR: In this article, the physicico-mechanical and microstructure properties of geopolymers synthesized from metakaolin activated with sodium silicate solution were investigated using X-Ray diffraction (XRD) and the micro-structure of the paste and the interfacial transition zone (ITZ) between the aggregate and the matrix of a geopolymer were studied by using transmission Electron Microscope (TEM) and scanning Electron microscope (SEM).

Fluorene Removal by Biosurfactants Producing Bacillus megaterium
Nuning Vita Hidayati,Endang Hilmi,Abdul Haris,Hefni Effendi,Michel Guiliano,Pierre Doumenq,Agung Dhamar Syakti +6 more
TL;DR: The results clearly demonstrated that carbon substrates affect biosurfactant production in terms of yield, and that the increase of fluorene removal was due to the presence of the amended crude biosurFactant from MSM-AA and MSM-CO, respectively, after 28 days.
Journal ArticleDOI
Pervaporation membrane based on laterite zeolite-geopolymer for ethanol-water separation
Subaer,Abdul Haris,Andi Irhamsyah,Anita Dewi Permatasari,Susilo Sudarman Desa,Resky Irfanita,Sari Wahyuni +6 more
TL;DR: In this paper, the performance of inorganic membrane made from a zeolite-geopolymer for pervaporation of ethanol-water separation was evaluated using scanning electron microscopy (SEM).
Gamma Ray Radiation Mutant Rice on Local aged Dwarf
Abdul Haris,Kamaruzaman Jusoff +1 more
TL;DR: The results showed that 200 gray dose of radiation with the potential to generate mutants that are shorter and faster harvesting showed that a very low percentage are very large percentage of empty grains with either radiation treatment on the Ase Lapang and Mandoti varieties.
