There are many determining factors for improving business performance including market leadership orientation, investment level, and innovation strategy. Therefore, research is needed on the determining factors of improving the performance of small and medium micro enterprises (MSMEs). The population in this study is MSME of marine fish processing home industry in Bangkalan Regency, Madura, Indonesia. Data collection is through surveys with respondents selected purposively as many as 162 of these MSME entrepreneurs. The research measuring instrument used was a questionnaire with a 1-5 Likert scale. Data from the respondents were then analyzed in SEM, the Lisrel program............

Keywords - Market Leadership Orientation, Investment Level, Innovation Strategy, and Business Performance.

This paper presents an optimal sizing of PV/diesel hybrid micro-grid system (HMGS) with battery energy storage using multi-objective bat algorithm (MOBA). The proposed method aims at finding the configuration, among a set of systems components, which meets the desired system reliability requirements, with the lowest value of levelised cost of energy. Modelling a hybrid PV/diesel/battery system is considered as the first step in the optimal sizing procedure. The second step consists to optimize the sizing of a system according to the loss of power supply probability (LPSP) and the levelised cost of energy (LCOE) concepts. Considering various types and capacities of system devices, the configurations which can meet the desired system reliability are obtained by changing the type and size of the devices systems.........

Keywords - Multi-objective bat algorithm, hybrid micro-grid system, loss of power supply probability, levelised cost of energy.

Binder-jet 3D printing is one of the additive manufacturing (AM) techniques employed in the fabrication of intricate parts, by utilizingmetalpowders. Manyimplementations of AM existfrom areas as diverse as the foodindustry to biomedicalengineering;such a broad-spectrum usage of thistechnologymakesitextremely attractive whencombinedwithitslowcost, reliability, color range, and complexityabilities. [1]. In this work, a method of making metal matrix composite was adopted which involves printing metal samples from gas atomized powder and infiltrating a lower melting metal into the porous sites of the sample.To achieve this, gas atomized structural amorphous metal (SAM) alloy powder was used for Binder-jet 3D printing of the base samples, while Bronze pellets were utilized for unpressurized liquid metal infiltration because of its lower melting temperature and high ductility.The SAM alloy powder was first characterized by Morphologi G3. The samples obtained were characterized by scanning electron microscopy.............

Keywords - Amorphous Metal, Binder-jet printing, Infiltration, Porosity, Density.

Ever since the beginning, wood and its composite has been tremendously used for so many purposes in construction industry, such as beams, columns, piers or wall partitions in building. Therefore, it is imperative to research into the strength, resistance, breakpoint and deflection characteristics of wood composite materials in order to recommend its appropriate usage.

In this work we use a numerical scheme based on fractional step method to solve the initial-boundary value problem arising from the modeling of the plane Couette flow by the eight velocity spatial Broadwell model. We show that the scheme is convergent and we perform a comparison with an exact solution. A good agreement is observed.
