Konstelasi Relasi Antar Aktor dalam Gerakan Penolakan Tambang Emas di Desa Pace Kecamatan Silo Kabupaten Jember 2016
This study aimed to analyze the movements and actors in the resistance movement of gold mining in the Pace village Subdistrict Silo, Jember regency. This research was using the Qualitative method include in-depth interviews and field in research studies,In addition collecting documents related to this research. This research had resulted, in finding the relationships between actors prone to be a trigger of conflict and led to the refusal movement made by the village community of Pace. Conflict of individuals who had an influence that made this conflict had became a mass conflict involving the community at large. Meantime, besides individual behalf, the state also had behalf for mining through PT Antam. The presence of the state in gold mining in the Pace village had become new chapter to the people who reject gold mining in the Pace village
Effect of rainfall patterns on concentration of CO2, soil temperature and matric suction for acidic barren soil
This study is based on field monitoring of a soil-atmosphere toward on acidic barren
soil. CO2 in the cavity are dependent on climatic parameters, mainly on the outdoor
temperature during rainfall. Observations were taken over a longer period of time. Maximum
CO2 values in the barren slope are reached in the warmest months and are in accordance with
soil CO2 values. The maximum CO2 concentration in the barren slope is 3022 ppm on average,
while the minimum is 2438 ppm. To describe the field findings, CO2 production and diffusion
experiments related to the soil behavior were developed. The results showed that the soil CO2
production increases as the soil temperature and matric suction increase. The relationship
between the gas diffusion coefficient and soil water suction is necessary data (i.e water
evaporation or CO2 evolution above the soil surface)
Infectious diseases epidemic threats and mass gatherings: Refocusing global attention on the continuing spread of the Middle East Respiratory syndrome coronavirus (MERS-CoV)
Media and World Health Organization (WHO) attention on Zika virus transmission at the 2016 Rio Olympic Games and the 2015 Ebola virus outbreak in West Africa diverted the attention of global public health authorities from other lethal infectious diseases with epidemic potential. Mass gatherings such as the annual Hajj pilgrimage hosted by Kingdom of Saudi Arabia attract huge crowds from all continents, creating high-risk conditions for the rapid global spread of infectious diseases. The highly lethal Middle Eastern respiratory syndrome coronavirus (MERS-CoV) remains in the WHO list of top emerging diseases likely to cause major epidemics. The 2015 MERS-CoV outbreak in South Korea, in which 184 MERS cases including 33 deaths occurred in 2 months, that was imported from the Middle East by a South Korean businessman was a wake-up call for the global community to refocus attention on MERS-CoV and other emerging and re-emerging infectious diseases with epidemic potential. The international donor community and Middle Eastern countries should make available resources for, and make a serious commitment to, taking forward a "One Health" global network for proactive surveillance, rapid detection, and prevention of MERS-CoV and other epidemic infectious diseases threats
Antibacterial Activity as Inhibitors Pathogen Bacterial on Pond Shrimp of Extract Marine Biota Collected From Maspari Island, South Sumatera, Indonesia
Marine biota has variety of bioactive compound that is potential to be an antibacterial for shrimp ponds diseases. Some of marine biota has potential as antibacterial i.e. soft coral Sarcophyton sp., Sponge Aaptos sp., seaweeds Sargassum sp. and Halimeda sp. and mangroves Avicennia sp. and Rhizophora sp. species. This study is purposed to find the most potential marine biota as antibacterial. The research method was as follows; sampling, sample identification, extraction and antibacterial activity test. The results is soft coral and sponge extract Sarcophyton sp. has bioactivity against of shrimp bacteria pathogen such as Vibrio spp2. bacteria for around 6.3±0.1 mm, while Aaptos sp. has bioactivity against Vibrio spp1. bacteria for around 7.9+0.1 mm, Vibrio spp2. bacteria for around 7.2± 0.1 to 7.9±0.1 mm, Vibrio spp6. bacteria for around 7.5±0.2 mm, Escherichia coli for around 7.2±0.1 mm and Staphylococcus aureus for around 15.9±0.2 mm. Seaweed extract activity found only of Sargassum sp. which has antibacterial activity against for around 7.1±0.0 mm for Vibrio spp6. and mangrove species activity has Rhizophora sp. extract which has bioactivity against Vibrio spp4. were 7.3±0.1 mm and E. coli bacteria were 6.7±0.1 mm. The most potential marine biota as antibacterial is showed on sponge Aaptos sp.. with an inhibitory zone for around 15.9±0.2 mm (for S. aureus bacteria)

Magnetic table for levitating food for entertainment
In this paper, we discuss our work towards a new dining platform that uses magnetic levitating food and magnetic utensils in an initial prototype device. The ultimate goal of the project is a complete table with dynamic levitating food, but the current implementation is a set of levitating magnets that can be encased in food hovering over static locations. We investigated different weights and shapes of 3-D printed objects to mimic food and found that the levitating magnets are strong enough to support lightweight food. This magnetic levitating table can produce a playful and entertaining dining experience by moving and rotating to stay in place. The key novelties of this paper are the integration of food with a magnetic levitating table for playful interactions and novel dining experiences
Analyzing three-player quantum games in an EPR type setup
We use the formalism of Clifford Geometric Algebra (GA) to develop an
analysis of quantum versions of three-player non-cooperative games. The quantum
games we explore are played in an Einstein-Podolsky-Rosen (EPR) type setting.
In this setting, the players' strategy sets remain identical to the ones in the
mixed-strategy version of the classical game that is obtained as a proper
subset of the corresponding quantum game. Using GA we investigate the outcome
of a realization of the game by players sharing GHZ state, W state, and a
mixture of GHZ and W states. As a specific example, we study the game of
three-player Prisoners' Dilemma.Comment: 21 pages, 3 figure
Intelligent evacuation management systems: A review
Crowd and evacuation management have been active areas of research and study in the recent past. Various developments continue to take place in the process of efficient evacuation of crowds in mass gatherings. This article is intended to provide a review of intelligent evacuation management systems covering the aspects of crowd monitoring, crowd disaster prediction, evacuation modelling, and evacuation path guidelines. Soft computing approaches play a vital role in the design and deployment of intelligent evacuation applications pertaining to crowd control management. While the review deals with video and nonvideo based aspects of crowd monitoring and crowd disaster prediction, evacuation techniques are reviewed via the theme of soft computing, along with a brief review on the evacuation navigation path. We believe that this review will assist researchers in developing reliable automated evacuation systems that will help in ensuring the safety of the evacuees especially during emergency evacuation scenarios
