Analisis Perbandingan Metode Perkalian Array dan Booth

Di era komputasi digital sekarang ini, optimasi sistem komputasi yang terdiri dari berbagai operasi matematika merupakan salah satu topik bahasan yang penting. Diantara operasi matematika, perkalian merupakan operasi dasar yang memiliki komplesitas, area, dan konsumsi daya paling tinggi dibandingkan operasi lainnya. Pada makalah ini, dibandingkan dua jenis teknik implementasi perkalian yang sampai saat ini masih terus dikembangkan, yaitu perkalian array dan perkalian Booth. Perbandingkan keduanya meliputi frekuensi clock maksimum yang dapat diterapkan, komplesitas, dan kecepatan proses komputasi. Perbandingan dilakukan dengan acuan perkalian signed binary dengan lebar data 4 bit dan 8 bit. Hasil analisa dan implementasi pada FPGA menunjukkan hasil bahwa perkalian array mempunyai keunggulan pada kecepatan proses komputasi, sedangkan perkalian Booth mempunyai kelebihan dalam hal komplesitas rangkaian

Comment on "Quantum Key Distribution in the Holevo Limit"

In a Letter, Cabello proposed a quantum key distribution (QKD) Protocol which attended to Holevo limit. In this comment, we show that Eve could use a simple plan to distinguish among quantum keys, without being detected by Alice and Bob. In following, we show that our approach is not restricted to Cabello Protocol. With attention to our Eavesdropping approach, it seems that Mor's arguments for no-cloning principal for orthogonal states is not general enough to avoid eavesdropping.Comment: REVTeX4, 1 page, no figure, A.

Studying the Formulation of Shallot (Allium Ascalonicum L.) Ethanol Extract Gel as Treatment of Excision Wounds in Rats

Onion bulbs (Allium ascalonicum L.) contain alkaloid compounds and saponins which can accelerate the wound healing process. Therefore, a study was conducted on the wound healing effect of excision of ethanol extract of onion bulbs (Allium ascalonicum L.) in the form of a gel against mice (Rattus novergicus). The purpose of this research was to study the stability of the preparation as well as the effectiveness and optimum concentration in excision wound healing from the ethanolic extract of shallot (Allium ascalonicum L.) in gel dosage form. The concentration variants used were 5%, 10%, and 20%. The method used was sample extraction by maceration and wound gel was made in 3 concentrations, namely 5%, 10%, and 20% then a stability test was carried out on the preparation by cycling test method at 4⁰C and 40⁰C for 6 cycles. Besides that, gel base was also used as a negative control and octadine® gel as a positive control, then the back skin of a rat (Rattus novergicus) was injured using a surgical knife. The results of the observation of the stability of the wound gel preparation were stable both at 4⁰C and at 40⁰C. Reduction of the length of the wound at the beginning of the treatment until the wound was completely closed showed that the ethanol extract gel preparation of shallot bulbs (Allium ascalonicum L.) could reduce and heal cuts in rats with a concentration of 20% which showed the most effective wound healing effect.Onion bulbs (Allium ascalonicum L.) contain alkaloid compounds and saponins which can accelerate the wound healing process.

Kelayakan Hutan Rakyat dalam Skema Perdagangan Karbon : Kawasan Hutan Rakyat Kampung Calobak, Desa Tamansari, Kecamatan Tamansari, Kabupaten Bogor, Propinsi Jawa Barat

The rate of Indonesian forest destruction caused by deforestation and forest degradation contribute greatly to climate change and global warming. Development of Community Forest could be potential in carbon sequestration and then go into Carbon Trading Scheme. Initiative to get the incentives for the management of Community Forests through carbon trading in the voluntary carbon market is a concrete step to participate in the adaptation and mitigation of climate change and gain maximum benefit from the ecosystem of the forest resources. Thus, based on the guidelines of LEI certification decision, the Calobak community forest management get the title of "DO NOT PASS". The assessment resulted that the community forest in Calobak under the Plan Vivo Standards only able to meet the four indicators of the 37 indicators or data that should be available

Magnetic properties and relaxation of the magnon populations in the super lattice [Fe/GaAs]

In the present work we study the properties of elementary excitations in a magnetic super lattice [Fe/GaAs] which is described in framework of the ferromagnetic Heisenberg system where the exchange and the dipolar interactions, the magneto-crystalline and surface anisotropies are all taking into account. The corresponding Hamiltonian is treated by the Green’s function method. The analytical expressions of the excitation spectrum and the magnetization per spin are obtained when the exchange is present alone. A good adjustment of calculated magnetization with the experimental results is obtained for various magnetic layer thickness . The deduced exchange integrals are in agreement with previous studies. The combined effect of dipolar interactions and surface anisotropy is studied numerically

Currently being implemented under the Merdeka Curriculum as a character education initiative is The Pancasila Student Profile Strengthening initiative. Finding out how the Pancasila Student Profile may promote national character and the methods teachers use to implement it to assist students develop moral character are the goals of this research. Class V of SDN Pasirkamuning I Kec. Telagasari Kab. Karawang was the site of this study. This kind of investigate, which portrays how teaches actualized the Pancasila Understudy Profile and the methodologies they utilized to do so, is subjective in nature. Three methods of gathering data are employed: documentation, interviews, and observation. The Project for Strengthening Pancasila Student Profiles employed project-based learning and habituation, which emphasizes character development in students, as techniques employed by instructors, according to observational data. Teachers have done a good job of implementing the strategy, according to research findings. Teachers must be imaginative in their lesson planning in order to apply this strategy effectively. The family and social surroundings, in addition to the function of the instructor, have a significant effect in how children grow as individuals
