ANALISIS PENERAPAN PRODUKSI BERSIH PADA INDUSTRI TEMPE

Tempe is one of Indonesia's special foods made from soybeans. This study aims to identify and analyze application of cleaner production to the tempe industry. Analysis of the application of cleaner production is done by the quick scanning method at each stage of the production process and then tested for its technical and economic feasibility (PBP). The analysis results of the application of cleaner production in the tempe industry are tool modification, fuel substitution, use of personal protective equipment, reuse, recycle and reduce. Based on the results of technical and economic feasibility tests, the alternative application of cleaner production in the form of solid waste utilization of soybean husks as animal feed is the first priority scale to be applied to the tempe industry

Percussive tool use by Taï Western chimpanzees and Fazenda Boa Vista bearded capuchin monkeys: a comparison

Percussive tool use holds special interest for scientists concerned with human origins. We summarize the findings from two field sites, Taï and Fazenda Boa Vista, where percussive tool use by chimpanzees and bearded capuchins, respectively, has been extensively investigated. We describe the ecological settings in which nut-cracking occurs and focus on four aspects of nut-cracking that have important cognitive implications, namely selection of tools, tool transport, tool modification and modulation of actions to reach the goal of cracking the nut. We comment on similarities and differences in behaviour and consider whether the observed differences reflect ecological, morphological, social and/or cognitive factors. Both species are sensitive to physical properties of tools, adjust their selection of hammers conditionally to the resistance of the nuts and to transport distance, and modulate the energy of their strikes under some conditions. However, chimpanzees transport hammers more frequently and for longer distances, take into account a higher number of combinations of variables and occasionally intentionally modify tools. A parsimonious interpretation of our findings is that morphological, ecological and social factors account for the observed differences. Confirmation of plausible cognitive differences in nut-cracking requires data not yet available.

Research on Design and Application of Control System in Machine Tool Modification

Technical reform of the used equipment in engineering, not only economizes the purchasing funds of the equipment, but also exploits the potential of the current equipment, at the same time, improves the level of automation of facilities and production quality. In this paper, the mathematics model and the system responding analysis on the mechanism are provided based on the dynamic analysis of mechanism. The design scheme of drilling machine workbench system has been optimized by improving the design and adopting appropriate compensations to system errors.
