Startup sebagai solusi dari berbagai permasalahan di Indonesia kini mulai mendapatkan sorotan. Tetapi sebagian banyak perusahaan yang mengembangkan startup hanya sedikit mampu bertahan dan berhasil menghasilkan profit. Menurut Forbes, angka kegagalan dalam bisnis mencapai 90%. Oleh karena itu penelitian ini dilakukan dengan tujuan untuk mengetahui faktor atau hambatan sebuah dapat berkembang. P...

Transmission control protocol (TCP) has undergone several transformations. Several proposals have been put forward to change the mechanisms of TCP congestion control to improve its performance. A line of research tends to reduce speed in the face of congestion thereby penalizing itself. In this group are the window based congestion control algorithms that use the size of congestion window to de...

Technology startups are important regional economic engines that recognized as drivers of sustainable growth. Understanding the factors influence their success is interest both to scientific community and practitioners. However, there currently no consensus in literature on how define a technology startup. Startup has multiple dimensions different theoretical approaches empirical contexts. Ther...

The development of innovative water disinfection strategies is of utmost importance to prevent outbreaks of waterborne diseases related to poor treatment of (drinking) water. Recently, the association of silver nanoparticles with the bacterial cell surface of Lactobacillus fermentum (referred to as biogenic silver or bio-Ag(0)) has been reported to exhibit antiviral properties. The microscale b...

First wall and blanket (FW/blanket) design is a crucial element in the performance and acceptance of a fusion power plant. High temperature structural and breeding materials are needed for high thermal performance. A suitable combination of structural design with the selected materials is necessary for D /T fuel sufficiency. Whenever possible, low afterheat, low chemical reactivity and low acti...

l%e partitioning and transmutation concept (P-T) has as a mission the reductio~ by many orders of rnagnitudq of certain undesirable nuclides in the waste streams. Given that only a very small fiction of spent fiel can be “rejected” by a P-T enterp~ a P-T system must therefore be capable of accommodating a wide range of spent fuel characteristics. Variability of nuclide composition (i.e. the fee...

The technical feasibility of applying anaerobic digestion for reduction and stabilization of the organic fraction of solid wastes generated during space missions was investigated. This process has the advantages of not requiring oxygen or high temperature and pressure while producing methane, carbon dioxide, nutrients, and compost as valuable products. High-solids leachbed anaerobic digestion e...

Bio-ethanol reforming was studied using a plasma-catalytic reactor for hydrogen production at low temperature and atmospheric pressure without diluent gas or external heating. The plasma applied was a DC pulse discharge (corona) plasma. The water gas shift (WGS) catalyst was put just below the cathode electrode. The discharge generated heat was effectively used for feed vaporization and theWGS ...

A new process consisting of a landfill bioreactor, partial-nitritation (PN) and the anammox process has been developed for landfill leachate treatment. In this study, the landfill bioreactor exhibited excellent performance in methane-rich biogas recovery, with a specific biogas yield of 0.47 L gas g(-1) COD and methane percentages of 53-76%. PN was achieved in the aerobic reactor by high free a...

In order to achieve high power generation efficiency, facility compactness, safety, and coexistence with fuel tritium in the 3 G Wth class FFHR(Force Free Helical Reactor) plant, optimization, performance operation scenario of system plant model using axial flow type uniaxial supercritical CO2 gas turbine were examined. As a result, following conclusions obtained. (1) The most efficient compact...
