This research aims i) to determine the density profile and calculate the ground state energy of a quantum dot in two
dimensions (2D) with a harmonic oscillator potential using orbital-free density functional theory, and ii) to
understand the effect of the harmonic oscillator potential strength on the electron density profiles in the...

Chlorophyll-a is a pigment that is contained in phytoplankton. Through the photosynthesis process, chlorophyll-a plays
an important role in the global carbon cycle. The purpose of this research is to investigate the effect of global warming
on chlorophyll-a concentration in Indonesian waters. The data used includes the monthly data of sea surface
temperatures...

The diversity of wild banana species (genus Musa, listed in Flora of Java) has been revised. The present taxonomic
study is based on morphological characteristics observed in the herbarium specimens deposited at the Herbarium
Bogoriense (BO), living collections in the Bogor Botanical Garden, the Cibodas Botanical Garden, and during the
explorations done at...

The recycling of residual agricultural biomass using anaerobic digestion allows for the recovery of biomass carbon and
nutrients as sources of energy and fertilizer. The obstacles that are encountered in this process include the
lignocellulosic structure of biomass tissue and its high carbon-to-nitrogen (C:N) ratio. This study evaluates the codigestion
system of pretreated...

A microfungal survey was carried out on the living leaves and litters of Licuala bidentata in Kubah National Park in
Sarawak, Malaysia. A total of 400 leaf segments (200 segments for each leaf type) were plated on two isolation media
(water agar and malt extract agar) for endophytic and saprophytic fungal isolation....

Oxidative DNA damage caused by propyl gallate (PG) and 2,6-di-tert-butyl-p-benzoquinone (BHT-quinone, a
metabolite of butylated hydroxytoluene (BHT)) was analyzed from the 8-hydroxy-2¢-deoxyguanosine (8-OHdG)
formation in calf thymus DNA and DNA base, 2¢-deoxyguanosine (dG). PG in the presence of CuCl2 increased the 8-
OHdG formation in calf thymus DNA by around 9.17 times as...

Polyclonal antibodies of aflatoxin B1 were successfully produced from New Zealand White female rabbits after
immunization by the hapten of aflatoxin B1-carboxymethyl hydroxylamine hemihydrochloride (AFB1-CMO)
conjugated with bovine serum albumin (BSA) as the antigen. The hapten was synthesized using the carbodiimide
method with CMO as a linker. Absorption peaks at 362, 264, and...

Two flavonoid compounds, 5,7,3?,4?-tetrahydroxy-6-geranylflavonol (1) and kaempferol 7-O-β-glucose (2) have been
isolated from the leaves of Macaranga hispida (Blume), Mull.Arg. Isolation and purification were conducted by
chromatography methods and chemical structure characterization was carried out by spectroscopic methods. The
5,7,3?,4?-tetrahydrxyi-6-geranyl flavonol (1) and kaempferol 7-O-glucose (2) had moderate cytotoxic activity against
murine leukemia P-388...

Organic photovoltaic (OPV) devices have lower efficiency, shorter lifetimes, faster degradation, and poorer stability than
inorganic photovoltaics (IPV) in ambient conditions. In this paper, the equivalent electrical circuit of a two-diode model
effectively extracts the model-fit electrical photovoltaic (PV) parameters from degraded OPV devices, especially the
series (Rs) and shunt (Rsh) resistances. The...

Mannan is an abundant polysaccharide that can be found in konjac (Amorphophallus sp.). Mannan can be enzymatically
hydrolyzed using mannanase to produce manno-oligosaccharides which can be used as a prebiotic. The aims of this
research are to determine the production time of mannanase from Streptomyces lipmanii, perform enzyme
characterization, optimize the hydrolysis time,...
