Published: November 2019

The supply chain is a scapegoat for the fluctuation price of beef. This research was intended to find out whether the supply chain triggers the main increase of beef prices as assumed by various parties. This qualitative descriptive study found that there were three supply chain pathways with the shortest chain that was a producer to consumer. The longest chain were suppliers, producers, consumers, and two intermediaries (blantik and retailer). Long and short of supply chain did not impact on selling prices to consumers and only affected the number of producer profits. Fluctuations in beef prices should not be based on the supply chain because the supply chain is a bridge at the limitations of the parties in the supply chain. There are other determinants that can be the focus of solutions for controlling beef prices.

Authors: Octavia S , Raubaba H S , Simorangkir Y V
Published: November 2019

Concrete is a building material that is generally widely used as a house structure material in Indonesia. This is very possible considering that the concrete forming material consisting of sand, cement, and gravel is a material that is available in nature and is relatively easy to find. But in certain areas such as in Merauke, there are no materials such as gravel and sand so wood and steel are alternative substitutes for concrete. This study aims to analyze and compare two types of semi-permanent houses that use different materials on the main structure, namely wood material, and steel material. This research is qualitative research with the following stages of research, namely determining the home mouse sample, interviewing people who are considered to have competence in the field of architecture and direct field observation. The results showed that in terms of costs, semi-permanent wood houses were relatively cheaper compared to semi-permanent steel houses. In terms of the appearance of the building, steel material has more advantages, namely not shrinking so that cracks that occur on the wall due to shrinkage of the material as happened in semi-permanent homes of wood can be minimized.

The construction of infrastructure on the ground that the carrying capacity is low resulting in a huge drop and lateral movement. Various methods have been developed to overcome these problems, particularly with the method of waste utilization. Therefore, the authors wanted to determine the effect of the use of woven plastic bottle waste on soil with low bearing capacity using experimental research methods. Testing is done by looking at the deformation that occurs in the soft ground without reinforcement and by reinforcement using woven plastic bottles tier 1 and tier 2. From the test results on the ground deformation that is not given retrofitting a load of 4 kN is 45,5mm, whereas by strengthening the use of woven plastic bottles tier 1 and tier 2 with the same load of 4 kN is 41,60mm and 38,20mm, so it can be concluded that the ground by reinforcement ply weaved plastic bottle 1 has increased by 9.38% strength and for woven layer 2 by 19.11% against the vertical deformation that occurs. Judging from the patterns of deformation modeling results is included in the pattern of local shear failure.

Poverty and income inequality remain serious problem in developing countries, and Indonesia is no exception. The number of poor people in Indonesia was 9.82 percent in 2018. This fact shows that poverty level in Indonesia is still need to reduce. The study deals with the role of zakat in social and economic changes in terms of poverty and food security of poor households after receiving zakat. The research employed qualitative methods. The results show that, pattern of zakat aid distributed by the National Zakat Amil Agency (called, BAZNAS) to the poor households in the form of IDR 300,000 (1USD=14, 000 IDR) in cash and/or rice (non-cash); there are two patterns acts of poor households in utilizing zakat (consumptive patterns and productive patterns). It indicates that, some poor households have been giving production capital, and in turn positively affects poverty reduction and food security situation. It implies that zakat is one possible route to reduce poverty and strengthen household’s food security in the country.

Asymptotically Poincaré surfaces in quasi-Fuchsian manifolds
Authors: Quinn Keaton
Published: November 2019

We introduce the notion of an asymptotically Poincaré family of surfaces in an end of a quasi-Fuchsian manifold. We show that any such family gives a foliation of an end by asymptotically parallel convex surfaces, and that the asymptotic behavior of the first and second fundamental forms determines the projective structure at infinity. As an application, we establish a conjecture of Labourie from [J. London Math. Soc. 45 (1992), pp. 549–565] regarding constant Gaussian curvature surfaces. We also derive consequences for constant mean curvature surfaces.

Published: November 2019

How BMP signaling and other body size regulators interact is not clear. We found interactions between Caenorhabditis elegans DBL-1/BMP and ECM, proteins that may modify or secrete DBL-1, and the SET domain protein BLMP-1. DBL-1 signaling may control downstream targets, some through BLMP-1, that affect size either directly or by feeding back on DBL-1 signaling.
Arf-GEF localization and function at myosin-rich adherens junctions via coiled-coil heterodimerization with an adaptor protein
Authors: Zheng Shiyu , West Junior J. , Yu Cao Guo , Harris Tony J. C.
Published: November 2019

Epithelial morphogenesis often depends on regulation of actomyosin networks at adherens junctions. The Arf-GEF Steppke has been implicated in a negative feedback loop that locally down-regulates junctional actomyosin. We find that coiled-coil heterodimerization with the adaptor protein Stepping stone recruits Steppke to myosin-rich adherens junctions to facilitate tissue stretching during Drosophila dorsal closure.
