Effectiveness of Etanol Extract Bajakah Wood (Spatholobus sp.) on the Growth of Staphylococcus aureus ATCC 25923
Authors: Banjarnahor Rifanny Paruma 
Published: August 2024

Background: Infectious diseases are still an important issue for Indonesia. One of the opportunistic bacteria that causes various infectious diseases is Staphylococcus aureus. There is a need for new alternative treatments that have the same high potential as antibiotics. Bajakah wood (Spatholobus sp.) is a plant that grows abundantly in the tropical forests of Central Kalimantan. This plant has the potential antibacterial potential because it contains secondary metabolite compounds, namely alkaloids, tannins and glycosides.Objective: This study aims to determine the effectiveness of Bajakah wood (Spatholobus sp.) on the growth of S. aureus ATCC 25923 bacteria through antimicrobe sensitivity test.Methods: In this study, three different methods were used, the disc method, the well method and the Whatman paper method using a concentration of 5%; 15%; 25%; 50% and 100% extract.Results: The results showed that the ethanol extract of Bajakah Wood (Spatholobus sp.) had antibacterial activity against S. aureus ATCC 25923 at the lowest concentration, namely 5%. The disk method obtained an average inhibition zone of 11.1 mm, the well method obtained an average inhibition zone of 16.8 mm and the Whatman paper method obtained an average inhibition zone of 10.8 mm.Conclusion: From this study, the ethanol extract of Bajakah wood (Spatholobus sp.) has antibacterial potential against S. aureus bacteria with its secondary metabolite compounds.

The COVID-19 pandemic had a significant impact on various countries, including Indonesia, in particular on the securing of the state budget and state financial stability in anticipation of the systemic and comprehensive impact of the pandemic. This deviation is not in line with the Indonesian constitution, welfare state principles, and even regulations based on the principles of good legislation. This article will examine three aspects of the problem: firstly, the formation of Government Regulation Number 1 of 2020 (Perppu) concerning State Financial Policy and Stability under COVID-19 countermeasures by the formation mechanism; secondly, the constitutionality issue in the drafting of Perppu; and thirdly, the legal issue of Article 27 on the immunity of officials who carry out financial policies. This paper employs a combination of normative legal research methods, including a statutory approach, a legal conceptual approach, a legal fact approach, and a relevant case law approach. The result of the research is that Perppu is a policy in an emergency period that contains a policy of relaxation of the implementation of the APBN is constitutional. The form of deviation that appears from Perppu is that this Perppu implements financial relaxation or sets state financial policies without involving the DPR. This has been constitutionally confirmed by Article 12 of the 1945 Constitution that the government and the DPR must determine state financial policies together. Although the constitutionality of Perppu in terms of fiscal policy is not in question, the provisions of Article 27 of Perppu that are unconstitutional can be cancelled by the Constitutional Court. The legality of Perppu relating to immunity must be implemented by prioritising the principle of good faith in carrying out the duties and functions of each state financial stakeholder during the emergency period.

Abstract
Deep and thick weathered granite crusts widely distributed in Xiangdong area, Hunan Province, due to their special structure, often induce geological disasters such as landslides under the conditions of excavation or atmospheric precipitation. In this article, using the direct shear test, X-ray diffraction test and scanning electron microscope test, the mechanical properties and the response mechanism of the microstructure of the granite residual soil in eastern Hunan area under different states were studied, and the structural damage mechanism of the granite residual soil was analysed. Based on the comprehensive structural potential, the theory characterizes its structure. The results show that the granite residual soil is mainly composed of minerals such as quartz, mica, kaolinite and feldspar, and it also contains a small amount of chlorite and calcite. The damage is mainly reflected in the attenuation of cohesion, while the change of the internal friction angle is small. The microscopic manifestation is the failure of the bridging structure between the aggregates, and the inter-granular pores are interconnected. The difference and shear strength response reflect the susceptibility to disturbance of granite residual soil and reflect that the structural strength has been damaged under the disturbance of human factors.
Tiere als „lebende Artefakte“. Die Erfindung des Rassehundes als kulturelle Kategorie und als materielles Objekt
Authors: Heintz Bettina 
Published: August 2024

Zusammenfassung
Der Aufsatz befasst sich mit der Erfindung des Rassehundes in der zweiten Hälfte des 19. Jahrhunderts. In dieser Zeit etablierte sich eine kategoriale Ordnung, die Hunde neu nach ihrer „Rasse“ klassifizierte. Gleichzeitig entstand ein durch Züchtung hergestelltes „lebendes Artefakt“– der sog. „Rassehund“ –, in dessen Körper die Rassemerkmale physisch eingeschrieben waren. Meine Rekonstruktion der Erfindungsgeschichte des Rassehundes zeigt, dass die Einteilung und Produktion von Tieren nach ihrer Rasse nicht weniger kontingent und kulturell konstruiert ist wie die entsprechende Unterscheidung bei Menschen. Anhand einer Analyse der damaligen Zuchttheorien und ihrer Verschränkung mit den Rasseideologien dieser Zeit dokumentiert der Beitrag den theoretischen Gewinn einer Auffassung, die den Begriff der Tierrasse entbiologisiert, und diskutiert die Folgen, die eine solche Entbiologisierung für die Annahme einer grundsätzlichen Differenz zwischen Menschen und Tieren hat.
