Identifikasi Hama Kutu Putih pada Bibit Sengon (Falcataria Moluccana (Miq.) Barneby And J.W Grimes) di Persemaian Puslitbang Kehutanan
Commercial and community plantation of sengon commonly know as Moluccan albizia (Falcataria moluccana (Miq.) Barneby and J.W Grimes) requires qualified transplant, but the supply of such transplant seed is constrained by mealybug pest attack in the nursery. The purpose of this study is to identify the mealybug species that attack Moluccan albizia seeds. Observation of the symptoms mealybug attack in the nursery and identification of mealybug species has been performed in the nursery of Forest Research Center, Bogor. The results were mealybug that attack nursery was Ferrisia virgata belong to the famili Pseudococcidae, the Order Hemiptera. White mealybug colonized the stems and leaves of seeds. The leaves fall and plant wilted when the attack become serous. Predator Curinus coerulus and Coccinella repanda was suggested to be used to control mealybug

High Performance PbS Quantum Dot/Graphene Hybrid Solar Cell with Efficient Charge Extraction.
Hybrid colloidal quantum dot (CQD) solar cells are fabricated from multilayer stacks of lead sulfide (PbS) CQD and single layer graphene (SG). The inclusion of graphene interlayers is shown to increase power conversion efficiency by 9.18%. It is shown that the inclusion of conductive graphene enhances charge extraction in devices. Photoluminescence shows that graphene quenches emission from the quantum dot suggesting spontaneous charge transfer to graphene. CQD photodetectors exhibit increased photoresponse and improved transport properties. We propose that the CQD/SG hybrid structure is a route to make CQD thin films with improved charge extraction, therefore resulting in improved solar cell efficiency

The Evolution of Compact Binary Star Systems
We review the formation and evolution of compact binary stars consisting of
white dwarfs (WDs), neutron stars (NSs), and black holes (BHs). Binary NSs and
BHs are thought to be the primary astrophysical sources of gravitational waves
(GWs) within the frequency band of ground-based detectors, while compact
binaries of WDs are important sources of GWs at lower frequencies to be covered
by space interferometers (LISA). Major uncertainties in the current
understanding of properties of NSs and BHs most relevant to the GW studies are
discussed, including the treatment of the natal kicks which compact stellar
remnants acquire during the core collapse of massive stars and the common
envelope phase of binary evolution. We discuss the coalescence rates of binary
NSs and BHs and prospects for their detections, the formation and evolution of
binary WDs and their observational manifestations. Special attention is given
to AM CVn-stars -- compact binaries in which the Roche lobe is filled by
another WD or a low-mass partially degenerate helium-star, as these stars are
thought to be the best LISA verification binary GW sources.Comment: 105 pages, 18 figure
