The behavioural theory of the firm (BTOF) claims that firms’ performance feedback is significant for strategic decision-making. Building upon this, we shift our focus from widely researched topic financial to sustainability performance. We theorize environmental (i.e. relative aspirations) influences their reshoring decisions. Based on a sample publicly traded manufacturing multinational enterp...

This study aims was to analyse the effect of substitution commercial ration with fermented reject water kale on economic performance super rooster native chickens. The material used 80 heads 5 week old a complete randomized design (RAL) 4 treatments replications each replication consisted treatment tried R0: 100% ration, R1: 90% + 10% kale, R2: 80% 20% 70% 30% kale. variables observed were prod...

Here we used dilute oxalic acid to pretreat a kraft bleached Eucalyptus pulp (BEP) fibers to facilitate mechanical fibrillation in producing cellulose nanofibrils using disk milling with substantial mechanical energy savings. We successfully applied a reaction kinetics based combined hydrolysis factor (CHFX) as a severity factor to quantitatively control xylan dissolution and BEP fibril deploym...

The electronic absorption spectra, ground-state geometries and electronic structures of symmetric and asymmetric squaraine dyes (SQD1-SQD4) were investigated using density functional theory (DFT) and time-dependent (TD-DFT) density functional theory at the B3LYP/6-311++G** level. The calculated ground-state geometries reveal pronounced conjugation in these dyes. Long-range corrected time depend...

The Circular Economy introduced new research challenges to be faced. Linear and circular supply chain comparisons require general methodologies obtain significant scalable results. A two-step methodology is here proposed facilitate the interpretation of results during a Life Cycle Assessment (LCA). Firstly, an LCA analysis has been conducted on four single-use - Polypropylene (PP), Polylactic a...

The demand for fresh catfish in Bogor Regency is very high, causing farmers to take this business opportunity produce more catfish. Feed contributes about 60% of operational cost, therefore reduce the production farmer uses black soldier fly (maggot) as a supplementary feed their cultured. This research aims analyze cultivation using maggot at fish-farmers group TPS3R Kayumanis Bogor, West Java...

The interaction between the rotor and stator is a major source of high amplitude pressure fluctuation flow-induced vibration in multistage centrifugal pumps. detrimental to reliable operation sensitivity severe if number stages more. In present experimental study, vertical submersible pump used measure level at Best Efficiency Points (BEP) determine influence stage operating speed on fluctuatio...
